Description

Technical Field

[0001] The present invention belongs to the field of generators, and in particular relates to a submersible piston generator set and a power generation method with high stability, high efficiency, high quality, high cleanliness, no resource consumption and low construction cost. Background Art

[0002] At present, the international energy crisis is getting worse and worse, and most countries in the world are facing energy shortages. In particular, with the continuous burning of a large amount of fossil energy, the emission of greenhouse gases such as carbon dioxide continues to increase, leading to the phenomenon of global warming, which has caused frequent natural disasters and major epidemics, seriously threatening human survival and security. Countries around the world are seeking new energy to replace fossil energy. Hydropower, wind power, solar power, etc., as clean energy, have been widely used in many countries. However, since hydropower is affected by factors such as season, weather, precipitation in flood and dry seasons, catchment area and reservoir capacity, and natural environmental conditions, wind power is affected by wind size, weather conditions, seasonal changes and natural environment, and solar power is affected by sunshine time, day and night changes, weather and seasonal changes, geographical location and natural environment, these power generation systems have unstable power production, low power quality, and even have a certain impact on the ecological environment. Moreover, the construction cost of these power generation facilities is very high. Therefore, mankind urgently needs to explore and use new energy, new power generation technology and equipment with high stability, high efficiency, high quality, high cleanliness, no resource consumption, and low construction cost.

[0003] Through scientific and technological literature retrieval and investigation and research, although some researchers are exploring the technology of using gravity and buoyancy to generate electricity, the existing gravity and buoyancy power generation technology simply uses the interaction force between gravity and buoyancy. The methods and technologies are too simple and do not solve the problems of gravity and buoyancy synergistic driving technology and equipment, nor the problems of power generation stability and power generation efficiency, resulting in small power generation, low power generation efficiency, low power stability, and poor power quality. As a result, these technical achievements lack innovation and practicality, and cannot achieve industrial development and large-scale production. So far, no gravity and buoyancy power generation technology and equipment has been truly put into commercial application in the market.

[0004] It is under the above social needs and background technology that the inventors, after long-term in-depth research and development and prototype testing, created the theory of cold static energy, created methods, technologies and equipment for generating electricity using cold static energy, invented the submersible piston generator set, and constructed a power generation system with high stability, high efficiency, high quality, high cleanliness, no resource consumption and low construction cost. Summary of the invention

[0005] The present invention provides a submersible piston generator set and a power generation method, which effectively solve the technical and equipment problems in the coordinated driving technology of gravity potential energy and buoyancy potential energy, and create a submersible piston generator set with high stability, high efficiency, high quality, high cleanliness, no resource consumption and low cost. The entire power generation process does not require the consumption of any fossil energy and nuclear materials such as coal, oil, and natural gas, does not generate any wastewater, exhaust gas, or waste emissions, and does not require the use of unstable natural forces such as wind, river water, lake water, waves, tides, geothermal energy, and solar energy, thereby ensuring the stability, continuity and high quality of power generation and truly creating a green, clean, and sustainable power production system.

[0006] The technical solution of the present invention is as follows:

It is the torque differences and torque differences generated by the submersible pistons or submersible piston strings and the gravity torque differences and torque differences generated by the liquid that continuously and stably drive the piston cylinder and the gravity box to rotate, and drive the engine rotating disk and the engine The central shaft rotates, and the driving wheel on the central shaft of the engine drives the power input wheel of the multi-stage gearbox to rotate. After the multi-stage gearbox changes speed, the power output wheel of the multi-stage gearbox outputs the speed and power required by the generator, driving the generator rotor winding to rotate and generate electricity; at the same time, the charging driving wheel of the multi-stage gearbox drives the charging generator rotor winding to rotate and generate electricity.

[0009] The support mechanism system further includes a rotating wheel rim, a starting and braking disc, a rotating wheel rim fixing bracket, a circular sheet-like stirrup, a rotating wheel rim supporting platform, a center axis outer edge hub platform, an engine center axis, a center axis bracket and an engine base. The rotating wheel rim is two circular ring bodies located on both sides of the outer end of the piston cylinder. The center of the rotating wheel rim is the center of the engine center axis. The two rotating wheel rims are connected and fixed by a number of parallel, horizontal and evenly distributed beams of the same length to form a whole. The starting and braking discs are two circular sheet-like ring bodies installed and fixed on the outer edge of the rotating wheel rim. The outer edge of the starting and braking discs is a gear structure. The rotating wheel rim fixing bracket is a support rod that connects and fixes the two rotating wheel rims to the center axis outer edge hub platform at equal distances. The middle part of all the rotating wheel rim fixing brackets is connected and reinforced by one or more circular sheet-like stirrups. The center axis outer edge hub platform is tightly connected to the engine center axis. The engine center axis is in a horizontal state. The engine center axis is supported by the center axis brackets on both sides of the engine rotating disk. The support, the central axis bracket is installed and fixed on the engine base, the engine base and the generator set base are the same base, the rotating wheel rim support platform, the central axis outer edge hub platform and the rotating wheel rim fixed bracket constitute the piston cylinder support platform, each submerged piston cooperative driving engine has a number of evenly distributed piston cylinder support platforms, each piston cylinder and the gravity boxes at both ends are installed and fixed on the piston cylinder support platform, each piston cylinder and the gravity box are filled with an equal amount of liquid, each piston cylinder has a submerged piston or a submerged piston string, two piston motion controllers and two piston fixed angle control switches, the rotating wheel rim, the starting and braking discs, the rotating wheel rim fixed bracket, the circular sheet stirrups, the rotating wheel rim support platform, the central axis outer edge hub platform, the piston cylinder and the gravity boxes at both ends, the liquid in the piston cylinder and the gravity box, the submerged piston or the submerged piston string, the piston motion controller, the piston fixed angle control switch, and the engine central axis constitute the engine rotating disk, and the engine rotating disk is the engine's rotating mechanism system and power generation system;

[0010] The piston cylinder and the gravity box are cylindrical closed boxes, with a gravity box at each end of the piston cylinder. The gravity box and the piston cylinder form an angle of 90 degrees or other angles, which is also called a "double elbow gravity box". The gravity box located at the rotating wheel rim end is the outer gravity box, the piston cylinder end located at the rotating wheel rim end is the outer end, the gravity box located at the hub platform end of the outer edge of the central axis is the inner gravity box, and the piston cylinder end located at the hub platform end of the outer edge of the central axis is the inner end. The outer gravity boxes at both ends of the piston cylinder are in opposite directions to the inner gravity boxes, and the piston cylinder and the gravity boxes at both ends are through-connected. The liquid can flow freely between the piston cylinder and the gravity boxes at both ends without seeping outward. Leakage, the length, shape, volume and capacity of each piston cylinder, each outer gravity box and each inner gravity box are exactly the same, the weight of the liquid in each piston cylinder and the gravity boxes at both ends is also exactly the same, each piston cylinder and the gravity box are evenly distributed in their rotation planes, ensuring that the engine rotating disk is completely balanced, a piston sliding groove parallel to each other is installed on the inner wall on both sides of each piston cylinder, and the submersible piston or submersible piston string performs a cyclic reciprocating motion under the constraint of the two parallel piston sliding grooves, and a piston motion controller and a piston fixed angle control switch are installed at the ends of the piston cylinder respectively, which are used to control the locking and starting of the submersible piston or the submersible piston string;

[0011] The liquid in the piston cylinder and the gravity box is used to carry the submerged piston or the submerged piston string to do the buoyancy movement. The length, shape, volume, capacity of the piston cylinder and the length, volume and weight of the submerged piston or the submerged piston string determine the volume and weight of the liquid in the piston cylinder and the gravity box. The liquid level of the liquid injected into the piston cylinder and the gravity box along the vertical direction of the piston cylinder must ensure that after the submerged piston or the submerged piston string floats out of the liquid surface, the piston motion controller can lock the submerged piston or the submerged piston string, that is, the liquid level of the liquid in the piston cylinder is just The piston motion controller can lock the height of the submerged piston or the submerged piston string just after the submerged piston or the submerged piston string floats out of the liquid surface, thereby ensuring that the submerged piston or the submerged piston string can perform cyclic reciprocating motion along the piston cylinder under the coordinated action of the liquid buoyancy and its own gravity in the piston cylinder; when the submerged piston cooperates with the engine to run, it is necessary to first inject an equal amount of liquid into all the piston cylinders and the gravity box. The liquid injected into the piston cylinder and the gravity box is clean water at room temperature. In special cases, oil, alcohol or other special liquids can also be used;

[0012] The submersible piston and submersible piston string are composed of a gravity body and a closed hollow float. The gravity body is placed in the middle position of the closed hollow float and fixed. The submersible piston is designed and made into a "shuttle" shape, that is, the two ends of the submersible piston are respectively designed and made into a cone, a hemispherical or a semi-ellipsoidal shape to reduce the liquid resistance of the submersible piston when it moves in the liquid; two or more groups of bearing pulleys are installed on the outer walls of both sides of the submersible piston along the direction of movement, and each group of bearing pulleys consists of three pulleys. A completely parallel groove-shaped, "L"-shaped or "T"-shaped piston sliding groove is installed on the inner walls of both sides of the piston cylinder. The submersible piston is installed on two parallel piston sliding grooves. The bearing pulleys on both sides of the plug are clamped in the middle of the parallel tracks of the two piston sliding grooves, so that the submerged floating piston can slide cyclically along the parallel tracks of the piston sliding grooves without leaving the piston sliding grooves; in order to efficiently utilize the stable, continuous and clean energy of buoyancy potential energy and gravity potential energy, the buoyancy potential energy and gravity potential energy can be effectively converted into a coordinated driving force, and the coordinated driving force can be converted into a rotational power, when designing and manufacturing the submerged floating piston, the liquid buoyancy of the submerged floating piston is always greater than its own gravity, so that the submerged floating piston always has the ability to float in the liquid in the piston cylinder. After an equal amount of liquid is injected into each piston cylinder and the gravity box, the submerged floating piston is in the coordinated action of the liquid buoyancy and its own gravity. The parallel track along the piston sliding groove continuously performs cyclic reciprocating motion, so that the submerged pistons on the left and right sides of the vertical line of the engine center axis produce torque difference and torque difference; at the same time, the liquid located in the piston cylinder and the gravity boxes at both ends of the piston cylinder continuously circulates, so that the liquid in the piston cylinder and the gravity box on the left and right sides of the vertical line of the engine center axis produces gravity torque difference and torque difference. It is the torque difference and torque difference generated by the submerged piston and the gravity torque difference and torque difference generated by the liquid that drive the piston cylinder and the gravity box to rotate, and drive the engine rotating disk and the engine center axis to rotate, and output power to the outside. The submerged piston string is a string body composed of two or more independent submerged pistons connected in series and tightly connected. The submerged piston string They are uniformly installed on the piston sliding groove, and as a whole, they perform cyclic reciprocating motion along the parallel track of the piston sliding groove under the coordinated action of the liquid buoyancy and their own gravity. The entire submersible piston string is designed and manufactured into a "shuttle shape", and the two submersible piston connecting parts are the same shape as the middle part of the submersible piston and are tightly connected, so that the connecting part of the two submersible pistons becomes a smooth columnar body, so as to reduce the liquid resistance when the submersible piston string moves in the liquid; compared with a single submersible piston, the submersible piston string can increase the weight of the driving mechanism, thereby increasing the torque difference and torque difference of the submersible piston strings on the left and right sides of the vertical line of the engine center axis, and improving the output power of the engine driven by the submersible pistons;

[0013] Regarding the starting and braking control system, after the same amount of liquid is injected into each piston cylinder and the gravity box, the weight of the engine rotating disk is greatly increased, and the inertia of the engine rotating disk is greatly increased. When the submerged piston generator set is started and stopped, it is necessary to provide auxiliary driving force for the start of the engine rotating disk and effectively brake the shutdown of the engine rotating disk. The starting and braking system is a control system for controlling the start and braking of the engine rotating disk, including a starting and braking controller and a starting and braking disk. The starting and braking controller includes a motor, a motor intelligent switch, a starting gear, a starting gear connecting mechanism, a brake pad, a brake pad driving mechanism, a starting button and a brake button. The motor and the motor intelligent switch are installed and integrated in the lower part of the starting and braking controller box, the starting gear connecting mechanism, the starting gear, the brake pad driving mechanism and the brake pad are installed and integrated in the upper part of the starting and braking controller box, and the starting button and the brake button are installed and fixed on the control panel of the intelligent control system. The intelligent control system is connected to the starting and braking system through a control cable, and is linked with the starting and braking system. Control. Each starting and braking disc is controlled by two symmetrically installed starting and braking controllers, which are installed and fixed on the base of the generator set. The motor of the starting and braking controller is powered by a battery. When the submersible piston generator set needs to be started, first open the electronic lock of the generator set, and then press the start button. The intelligent control system controls the motor start through the intelligent switch of the motor of the starting and braking controller. The motor first pulls the brake pad drive mechanism, so that the two brake pads on the brake pad drive mechanism are separated from the starting and braking discs, and the clamping effect of the brake pads on the starting and braking discs is released. Then, the motor pushes the starting gear through the starting gear connection mechanism to engage with the outer edge gear of the starting and braking disc, and assists in driving the starting and braking disc to rotate. The starting and braking discs drive the engine rotating disc and the engine center axis to rotate, so that the engine speed quickly reaches the set speed; when the speed sensor of the intelligent control system detects that the engine speed reaches the set speed, the intelligent control system controls the motor of the starting and braking controller to pull the starting gear connection mechanism, The starting gear is separated from the outer gear of the starting and brake disc, and the motor is controlled to be turned off through the motor intelligent switch; when the submersible piston generator set needs to be shut down, the brake button is pressed, and the intelligent control system controls the motor to start through the motor intelligent switch of the starting and brake controller. The motor pushes the brake pad drive mechanism to drive the two brake pads on the brake pad drive mechanism in a disc brake mode to slowly clamp and brake the starting and brake discs until the engine rotating disc stops rotating. At this time, when the speed sensor of the intelligent control system detects that the engine stops rotating, the intelligent control system controls the two brake pads to continue to clamp the starting and brake discs, and controls the motor to be turned off through the motor intelligent switch. Finally, the generator set electronic lock is locked. The generator set electronic lock refers to an electronic lock that cannot start the generator set after the submersible piston generator set is locked using the generator set electronic lock;

[0014] The intelligent control system is a control system for monitoring, controlling and providing fault warning for the entire power generation system composed of a submerged piston cooperatively driven engine, a multi-stage gearbox, a generator, a battery and a charging generator, including controlling the start and brake of the submerged piston cooperatively driven engine, monitoring the speed of the engine and the multi-stage gearbox, monitoring the battery power, controlling the start and stop of the charging generator, monitoring the voltage, current and power of the generator, monitoring the temperature of the generator and measuring the power generation. The intelligent control system includes a control box, a main board, a control panel, a display screen, a speed sensor, a voltage sensor, a current sensor, a temperature sensor, a control cable and a power cable. The control panel is equipped with a start button, a brake button, an electronic lock of the generator set, a safety operation control system, and a start button. The green indicator light for safe operation, the red indicator light for fault warning and the alarm buzzer are on; the display screen displays the frequency, voltage, current, power, power generation and generator temperature, battery charge data and working status of the charging generator; when the submersible pistons cooperate to drive the engine, multi-stage gearbox, generator, battery and charging generator to operate normally, the green indicator light for safe operation will light up and the red indicator light for fault warning will go out; when the starting and braking system fails, the engine speed is abnormal, the generator operating status is abnormal, or the battery or charging generator is abnormal, the green indicator light for safe operation will go out, the red indicator light for fault warning will light up and the alarm buzzer will beep to remind the staff to immediately check the fault and take countermeasures. The control box of the intelligent control system is installed and fixed on the base of the generator set.

[0015] The support mechanism system is a support system that supports and fixes all piston cylinders and gravity boxes and the entire engine, wherein the rotating wheel rim, rotating wheel rim fixing bracket, rotating wheel rim support platform, center shaft outer edge hub platform, engine center shaft, center shaft bracket and generator set base are the supporting structural main body of the support mechanism system; the rotating wheel rim fixing bracket is both a supporting mechanism for the rotating wheel rim and a fixing mechanism for the piston cylinder and the gravity box, one end of the rotating wheel rim fixing bracket is connected and fixed to the rotating wheel rim, and the other end is connected and fixed to the center shaft outer edge hub platform, the middle part of all rotating wheel rim fixing brackets is fastened and reinforced with one or more circular sheet-like stirrups, the circular sheet-like stirrups and the rotating wheel rim are concentric circle mechanisms, the rotating wheel rim support platform is formed by laying steel plates on two rotating wheel rims and their crossbeams, and the center shaft outer edge hub platform is a regular polygonal box centered on the center line of the engine center axis, tightly connected to the engine center axis Fixed connection, the two sides of the regular polygon box are made of regular polygon steel plates, and steel plates are laid and fixed between each side of the steel plates on both sides of the regular polygon to enhance the supporting strength and rigidity of the hub platform on the outer edge of the central axis. Each side plane of the regular polygon box corresponds to a piston cylinder, the outer end of the piston cylinder and the outer gravity box are installed and fixed on the rotating wheel rim support platform, the inner end of the piston cylinder and the inner gravity box are installed and fixed on the hub platform on the outer edge of the central axis, and the middle part of the piston cylinder is connected and fixed by a rotating wheel rim fixing bracket; the engine center shaft is the rotating shaft that carries the submerged piston to drive the engine power output, and is supported by the center shaft brackets on both sides of the engine rotating disk. The engine center shaft and the center shaft bracket are connected and supported by high-strength bearings to ensure the stability, accuracy and lubricity of the rotation of the engine center shaft; the generator set base is a mechanism that carries the submerged piston to drive the engine, the starting and braking controller, the multi-stage gearbox, the generator, the battery, the charging generator and the intelligent control system.

[0016] The piston cylinder and gravity box can be a balanced structure and an unbalanced structure. The piston cylinder and gravity box of the balanced structure means that each piston cylinder and each gravity box have the same thickness, caliber, shape, and length, and the piston cylinder and the gravity box have the same thickness and caliber. The outer gravity box and the inner gravity box at both ends of the piston cylinder have the same volume and capacity, and the piston cylinder is perpendicular to the plane of the hub platform on the outer edge of the central axis. The piston cylinder and gravity box of the balanced structure have good operating stability. On the premise of ensuring that the length, shape, volume, and capacity of each piston cylinder, the outer gravity box, and the inner gravity box are exactly the same and the weight of the liquid in each piston cylinder and gravity box is exactly the same, the piston cylinder and the gravity box can also be designed and manufactured into a piston cylinder and gravity box of an unbalanced structure. The unbalanced structure of the piston cylinder and gravity box means that the thickness of the two ends of the piston cylinder and the gravity box can be different. They can be designed as a piston cylinder with a large end and a small end and a gravity box with a large end and a small end. Moreover, the thickness and shape of the piston cylinder and the gravity box can be different. The volume and capacity of the outer gravity box and the inner gravity box at both ends of the piston cylinder can also be different. Moreover, the piston cylinder and the plane of the hub platform on the outer edge of the central axis may not be perpendicular. All the piston cylinders together with the outer gravity box can be installed at the same inclination angle in the direction of rotation, forming an unbalanced structural state. The unbalanced structure piston cylinder and gravity box have good operating stability, and can increase the gravity moment difference and torque difference of the liquid in the piston cylinder and the gravity box, thereby increasing the engine speed and output power.

[0017] The cross-sectional shape of the piston cylinder and the gravity box can be designed to be square, rectangular, polygonal, circular, elliptical or other suitable shapes. The piston cylinder and the gravity box can be made of iron, aluminum, stainless steel, metal alloy materials, acrylic (polymethyl methacrylate), PVC (polyethylene), PET (polyethylene terephthalate), resin, glass, ceramic materials or other suitable high-strength lightweight materials.

[0018] The shape of the gravity body in the middle of the submersible piston is determined according to the shape of the piston cylinder, and can be made into a cube, a cuboid, a polygonal column, a polyhedron, a cylinder, an elliptical cylinder and other suitable shapes. The gravity body of the submersible piston can be made of iron, stainless steel, lead, copper, high-density metal, high-density rock or other suitable high-density materials. The closed hollow buoy of the submersible piston can be made of iron, aluminum, light alloy, acrylic (polymethyl methacrylate), PVC (polyethylene), PET (polyethylene terephthalate), resin, ceramic or other suitable high-strength and light materials.

[0019] The engine rotating disk is a rotating mechanism system and power generation system of the engine driven by the submerged pistons. It is a completely balanced rigid body composed of a rotating wheel rim, a starting and braking disc, a rotating wheel rim fixing bracket, a circular sheet stirrup, a rotating wheel rim supporting platform, a hub platform at the outer edge of the central axis, a piston cylinder, an outer gravity box, an inner gravity box, equal amounts of liquid in the piston cylinder and the gravity box, a submerged piston or a submerged piston string, a piston motion controller, a piston fixed angle control switch, and an engine central axis. The entire engine rotating disk will not deform or shake during rotation. After an equal amount of liquid is injected into each piston cylinder and the gravity box, the submerged pistons in all piston cylinders perform cyclic reciprocating motion in turn under the coordinated action of the liquid buoyancy and their own gravity. This causes the submerged pistons on the left and right sides of the vertical line of the engine's central axis to produce torque differences and torque differences, and causes the submerged piston to apply a greater torque to the piston cylinder on the side with the greater torque, thereby driving the piston cylinder and the gravity box to rotate, and driving the engine rotating disk and the engine's central axis to rotate, and outputting power to the outside; at the same time, the liquid in all the piston cylinders and gravity boxes circulates in their respective piston cylinders and gravity boxes in turn, causing the liquid in the piston cylinders and gravity boxes on the left and right sides of the vertical line of the engine's central axis to produce a gravity moment difference and torque difference, and the liquid applies a greater torque to the piston cylinder and gravity box on the side with the greater gravity moment, and together with the submerged piston drives the piston cylinder and the gravity box to rotate, and drives the engine rotating disk and the engine's central axis to rotate, and outputs power to the outside.

[0020] The piston motion controller is a controller that directly controls the locking and starting of the submersible piston, ensuring that the submersible piston performs uniform and regular reciprocating motion. Each piston cylinder has two piston motion controllers, which are respectively installed and fixed on the inner walls at both ends of the piston cylinder. Each piston motion controller corresponds to one end of the submersible piston. When the submersible piston moves from one end of the piston cylinder to the other end, the piston motion controller at the other end of the piston cylinder immediately and automatically locks the submersible piston, controlling the submersible piston to stop moving. During the rotation of the engine rotating disk, when the submersible piston needs to start moving, the piston motion controller releases the submersible piston under the control of the piston fixed angle control switch, and the submersible piston starts to float under the action of the buoyancy of the liquid.

[0021] The piston fixed angle control switch is a switch controller that controls the opening state of the piston movement controller and allows the submerged piston to start moving according to the set angle between the piston cylinder and the vertical line of the engine center axis. Each piston cylinder has two piston fixed angle control switches, which are respectively installed and fixed on the inner walls at both ends of the piston cylinder, and are integrated with the piston movement controller. According to the speed requirement of the submerged piston to cooperatively drive the engine, the angle between the piston cylinder and the vertical line of the engine center axis is set as the starting angle of the submerged piston movement. The starting angle includes the starting angle above the horizontal plane of the engine center axis and the starting angle below the horizontal plane of the engine center axis. When the engine rotating disk rotates in a clockwise direction, when the piston cylinder rotates to the set starting angle below the horizontal plane of the engine center axis, the piston fixed angle control switch located at the outer end of the piston cylinder drives the piston movement controller to release the submerged piston, and the submerged piston located at the outer end of the piston cylinder opens. When the piston is rotated to the set starting angle above the horizontal plane of the engine central axis, the piston fixed angle control switch located at the inner end of the piston cylinder drives the piston motion controller to release the submerged floating piston, and the submerged floating piston located at the inner end of the piston cylinder starts to do the upward movement and quickly reaches the outer end of the piston cylinder, and the piston motion controller located at the outer end of the piston cylinder immediately locks the submerged floating piston, and the submerged floating piston at the inner end of the piston cylinder starts to do the upward movement and quickly reaches the outer end of the piston cylinder, and the piston motion controller at the outer end of the piston cylinder immediately locks the submerged floating piston, and the submerged floating piston is locked and released cyclically and regularly, which ensures that the submerged floating piston has a stable and accurate cyclic reciprocating motion cycle, and ensures that the submerged floating piston cooperates to drive the engine with a stable and accurate speed; when the engine rotating disk rotates in the counterclockwise direction, the piston fixed angle control switch is controlled in the same way; the piston fixed angle control switch and the piston motion controller are integrated and installed.

[0022] The multi-stage gearbox is a gearbox that is designed to meet the speed requirements of the generator and the charging generator and accurately regulate the output speed of the submerged piston cooperatively driven engine. The multi-stage gearbox includes a power input wheel, a power input wheel shaft, a multi-stage speed gear combination, a power output wheel, a power output wheel shaft, a charging drive wheel, a charging drive wheel shaft, a speed controller, and a gearbox housing. When the submerged piston generator set is working, the output speed and output power of the submerged piston cooperatively driven engine are calculated and determined, and according to the speed requirements of the generator and the charging generator, the speed controller adjusts the speed ratio of the multi-stage gearbox so that the output speed of the multi-stage gearbox meets the speed requirements of the generator and the charging generator. The multi-stage gearbox is installed and fixed on the base of the generator set.

[0023] Regarding the power generation method of the submersible piston generator set, the specific power generation method is as follows:

[0024] (1) Inject an equal amount of liquid. Inject an equal amount of liquid into each piston cylinder and gravity box to ensure that each piston cylinder and gravity box are filled with the same weight of liquid, so that each piston cylinder and gravity box have the same weight and the engine rotating disk remains in a completely balanced state; because the liquid buoyancy of the submerged piston is always greater than its own gravity, the submerged piston always has the ability to float in the piston cylinder injected with liquid;

[0025] (2) The rotation direction of the engine rotating disk is controlled by the direction indicated by the external gravity box. When all the external gravity boxes are installed in the clockwise direction, the submerged piston in the piston cylinder only makes a circular reciprocating motion along the piston cylinder and cannot change the rotation direction of the engine rotating disk. At the same time, the liquid in the external gravity box and the piston cylinder on the left side of the vertical line of the engine center axis always flows to the internal gravity box, so that the force arm of the center of mass of the liquid in all gravity boxes and the piston cylinder on the left side of the vertical line of the engine center axis is reduced. Since the weight of the liquid in each gravity box and the piston cylinder is the same and fixed, the sum of the gravity moment vectors of the center of mass of the liquid in all gravity boxes and the piston cylinder on the left side of the vertical line of the engine center axis is reduced; at the same time, the liquid in the internal gravity box and the piston cylinder on the right side of the vertical line of the engine center axis always flows to the external gravity box, so that the force arm of the center of mass of the liquid in all gravity boxes and the piston cylinder on the right side of the vertical line of the engine center axis is increased, so that The vector sum of the gravity moments of all gravity boxes and the center of mass of the liquid in the piston cylinder on the right side of the vertical line of the engine center axis increases, which makes the vector sum of the gravity moments of all gravity boxes and the center of mass of the liquid in the piston cylinder on the right side of the vertical line of the engine center axis much greater than the vector sum of the gravity moments of all gravity boxes and the center of mass of the liquid in the piston cylinder on the left side, so that the gravity boxes on the left and right sides of the vertical line of the engine center axis and the center of mass of the liquid in the piston cylinder produce gravity moment difference and torque difference. It is this gravity moment difference and torque difference that makes the liquid exert a greater torque on the side with a larger gravity moment, that is, the piston cylinder and the outer gravity box on the right side of the engine center axis, thereby driving the piston cylinder and the gravity box to rotate in the clockwise direction, and driving the engine disk and the engine center axis to rotate in the clockwise direction; conversely, when all the outer gravity boxes are installed in the counterclockwise direction, the engine rotating disk and the engine center axis rotate in the counterclockwise direction. Therefore, the direction indicated by the outer gravity box is the rotation direction of the engine rotating disk and the engine center axis;

[0026] (3) Control the power generation of the engine. When designing and manufacturing the submersible piston, the liquid buoyancy of the submersible piston is always greater than its own gravity, so that the submersible piston always has the ability to float in the liquid in the piston cylinder. When the engine rotating disk rotates in the clockwise direction, when the submersible piston located on the right side below the horizontal plane of the engine center axis approaches the right side of the vertical line at the lower part of the engine center axis, the piston fixed angle control switch drives the piston motion controller to release the submersible piston, and the submersible piston located at the rotating wheel rim end moves rapidly toward the hub platform on the outer edge of the center axis under the action of the liquid buoyancy. When the submersible piston reaches the hub platform on the outer edge of the center axis, the piston motion controller automatically locks the submersible piston, reducing the force arm of the submersible piston and also reducing the torque of the submersible piston. As the engine rotating disk continues to rotate When the engine is rotated, all the submerged pistons on the left side of the vertical line of the engine center axis are locked at the hub platform end of the outer edge of the center axis, so that the moment vector sum of all the submerged pistons on the left side of the vertical line of the engine center axis is minimized; at the same time, when the submerged piston on the left side above the horizontal plane of the engine center axis approaches the left side of the upper vertical line of the engine center axis, the piston fixed angle control switch drives the piston motion controller to release the submerged piston, and the submerged piston moves rapidly toward the rotating wheel rim under the action of the buoyancy of the liquid. When the submerged piston reaches the end of the rotating wheel rim, the piston motion controller automatically locks the submerged piston, so that the submerged piston The increase in the force arm of the floating piston also increases the torque of the submerged piston. As the engine rotating disk continues to rotate, all the submerged pistons on the right side of the vertical line of the engine center axis are locked at the rotating wheel rim end, making the moment vector sum of all the submerged pistons on the right side of the vertical line of the engine center axis the maximum. This creates the maximum torque difference and torque difference between the submerged pistons on the left and right sides of the vertical line of the engine center axis. It is the continued existence of this torque difference and torque difference that causes the submerged piston to apply a greater torque to the piston cylinder on the side with greater torque, thereby driving the piston cylinder and the gravity box to move evenly and regularly. It rotates regularly, and drives the engine rotating disk and the engine central axis to rotate, outputting power to the outside; at the same time, during the continuous rotation of the engine rotating disk, the liquid in each piston cylinder and gravity box circulates continuously and regularly, causing the piston cylinders and the liquid in the gravity box on the left and right sides of the vertical line of the engine central axis to produce gravity moment difference and torque difference. This gravity moment difference and torque difference causes the liquid to apply greater torque to the piston cylinder and gravity box on the side with greater torque, driving the piston cylinder and gravity box to rotate, and driving the engine rotating disk and the engine central axis to rotate, outputting power to the outside. It can be seen that the power generated by the submerged piston cooperatively driving the engine is the vector sum of the rotational torque of the submerged piston and the rotational torque of the liquid in the piston cylinder and gravity box; when the engine rotating disk rotates in the counterclockwise direction, the same power output can be obtained;

[0027] (4) Control the engine speed. The speed of the engine driven by the submersible piston is determined by the number, length, shape, volume, capacity of the piston cylinder and the gravity box, the weight of the liquid in the piston cylinder and the gravity box, the volume and weight of the submersible piston, and the starting angle when the submersible piston starts to move. After the number, length, shape, volume, capacity of the piston cylinder and the gravity box, the weight of the liquid therein, and the volume and weight of the submersible piston are determined, the engine speed can be accurately controlled by controlling the starting angle at which the submersible piston starts to move. The specific engine speed control method is as follows:

[0028] Calculate the one-way running time of the submersible piston in the piston cylinder: Since the liquid buoyancy of the submersible piston is always greater than its own weight, after the volume and weight of the submersible piston, the effective length of the submersible piston in the piston cylinder for cyclic reciprocating motion, and the liquid level height of the piston cylinder and the gravity box are determined, the liquid buoyancy and self-weight of the submersible piston can be accurately calculated first, and then, after calculating the resistance of the submersible piston in the liquid, the time required for the submersible piston to move from one end of the piston cylinder to the other end can be accurately calculated;

[0029] Control the speed of the engine: according to the one-way running time of the submerged piston in the piston cylinder, the angle between the piston cylinder and the vertical line of the engine center axis is set as the starting angle of the submerged piston movement. When the engine rotating disk rotates in the clockwise direction, when the piston cylinder located on the right side of the vertical line of the engine center axis rotates to any angle below the horizontal plane of the engine center axis, the piston fixed angle control switch drives the piston motion controller to release the submerged piston. Under the action of the buoyancy of the liquid, the submerged piston will float upward from the rotating wheel rim end and move rapidly toward the hub platform on the outer edge of the center axis. At this time, the torque of the submerged piston will decrease, so that the speed of the engine rotating disk will decrease; at the same time, when the piston cylinder located on the left side of the vertical line of the engine center axis rotates to any angle above the horizontal plane of the engine center axis, the piston fixed angle control switch drives the piston motion controller to release the submerged piston. Under the action of the buoyancy of the liquid, the submerged piston will float upward from the hub platform end on the outer edge of the center axis and move rapidly toward the rotating wheel rim. At this time, the torque of the submerged piston will increase, forming an opposite torsion force, so that the speed of the engine rotating disk will decrease. It can be seen that when the starting angle of the submersible piston movement is larger, the submersible piston is released to allow the submersible piston to start the upward movement, and the engine speed is smaller. When the starting angle of the submersible piston movement is smaller, the submersible piston is released to allow the submersible piston to start the upward movement, and the engine speed is greater. Therefore, according to the speed ratio of the multi-stage gearbox and the speed requirement of the generator, the starting angle of the submersible piston movement can be calculated and determined. According to the determined starting angle of the submersible piston movement, the movement of the submersible piston can be controlled by the piston fixed angle control switch and the piston motion controller, so that the reciprocating motion cycle of the submersible piston can be accurately controlled, thereby controlling the engine speed to meet the generator's requirements for the engine output speed; when the engine rotating disk rotates counterclockwise, the engine speed control method is the same as the above method;

[0030] (5) Calculate and determine the power of the engine. The power of the submerged piston cooperative drive engine is the sum of the power generated by the reciprocating motion of all submerged pistons and the power generated by the circulating flow of liquid in all piston cylinders and gravity boxes. The specific power calculation method is as follows:

[0031] For the submerged piston, according to the torque calculation formula M 活 =F×L, where M 活 is the moment of the submerged piston mass center, F is the gravity of the submerged piston mass center, and L is the vector distance between the submerged piston mass center and the vertical line of the engine center axis. According to the engine power generation method, the torque difference ΔM generated by the submerged pistons in the piston cylinders on the left and right sides of the vertical line of the engine center axis 活 for: Among them, F 活is the gravity of the center of mass of the submerged piston in each piston cylinder. The gravity of the center of mass of the submerged piston in each piston cylinder is equal. 右i is the vector distance between the mass center of the submerged piston in the ith piston cylinder to the right of the vertical line of the engine center axis and the vertical line of the engine center axis, L 左i is the vector distance between the mass center of the submerged piston in the ith piston cylinder on the left side of the vertical line of the engine center axis and the vertical line of the engine center axis, and n is the number of submerged pistons on one side of the vertical line of the engine center axis; after the number, length, shape, volume, capacity of the piston cylinders and the volume and weight of the submerged pistons are determined, the torque difference of the submerged pistons in the piston cylinders on the left and right sides of the vertical line of the engine center axis can be calculated. According to the engine speed control method, the engine speed can be determined. According to the engine power calculation formula P 活 =ΔM 活 ×N / 9549, where P 活 is the power generated by the reciprocating motion of the submerged piston, N is the engine speed, and the engine power calculation formula can be used to calculate the engine power driven by the submerged piston;

[0032] For the liquid in the piston cylinder and gravity box, according to the torque calculation formula M 液 =F×L, where M 液 is the gravity moment of the center of mass of the liquid in the piston cylinder and the gravity box, F is the gravity of the center of mass of the liquid in the piston cylinder and the gravity box, and L is the vector distance between the center of mass of the liquid in the piston cylinder and the gravity box and the vertical line of the engine center axis. When all the external gravity boxes rotate in the clockwise direction, the liquid in the external gravity box and the piston cylinder on the left side of the vertical line of the engine center axis always flows to the internal gravity box, which reduces the vector distance between the center of mass of the liquid in the piston cylinder and the gravity box on the left side of the engine center axis and the vertical line of the engine center axis; at the same time, the liquid in the internal gravity box and the piston cylinder on the right side of the vertical line of the engine center axis always flows to the external gravity box, which increases the vector distance between the center of mass of the liquid in the piston cylinder and the gravity box on the right side of the engine center axis and the vertical line of the engine center axis. This results in a gravity moment difference between the center of mass of the liquid in the piston cylinder and the gravity box on the left and right sides of the vertical line of the engine center axis, that is, Among them, ΔM 液 is the gravity moment difference between the piston cylinder on the left and right sides of the vertical line of the engine center axis and the center of mass of the liquid in the gravity box, F 液 is the gravity of the center of mass of the liquid in each piston cylinder and gravity box. If the volume and weight of the liquid in each piston cylinder and gravity box are the same, then the gravity of the center of mass of the liquid in each piston cylinder and gravity box is also equal. 右i is the vector distance between the i-th piston cylinder on the right side of the vertical line of the engine center axis and the center of mass of the liquid in the gravity box and the vertical line of the engine center axis, L 左iIt is the vector distance between the center of mass of the liquid in the i-th piston cylinder and gravity box on the left side of the vertical line of the engine center axis and the vertical line of the engine center axis. n is the number of piston cylinders on one side of the vertical line of the engine center axis. After the number, length, shape, volume, capacity of the piston cylinder and gravity box and the volume and weight of the liquid in the piston cylinder and gravity box are determined, the gravity moment difference between the center of mass of the liquid in the piston cylinder and gravity box on the left and right sides of the vertical line of the engine center axis can be calculated. According to the engine speed control method, the engine speed can be determined. According to the engine power calculation formula P 液 =ΔM 液 ×N / 9549, where P 液 is the power generated by the circulation of the liquid in the piston cylinder and the gravity box, N is the engine speed, and the power generated by the circulation of the liquid in the piston cylinder and the gravity box can be calculated by the engine power calculation formula. Therefore, the power P of the engine driven by the submerged piston is P = P 活 +P 液 When all the external gravity boxes rotate counterclockwise, only the engine rotating disk rotates counterclockwise, and the engine power is the same;

[0033] Applying the above engine power calculation formula to calculate the power of the submerged piston cooperative drive engine is a theoretical calculation method. In fact, the power of the submerged piston cooperative drive engine is affected by the liquid resistance when the submerged piston circulates back and forth in the liquid between the piston cylinder and the gravity box, the friction of the cylinder wall when the liquid circulates in the piston cylinder and the gravity box, the friction between the engine center axis and the bearing, and the air resistance when the engine rotating disk rotates in the air. Therefore, the actual power of the submerged piston cooperative drive engine can be measured by referring to the diesel engine torque measurement method and power measurement method;

[0034] (6) Increasing the output power of the engine by coaxial series operation of submersible piston cooperatively driven engines. When the output power of a submersible piston cooperatively driven engine cannot meet the power requirement of the generator, two or more submersible piston cooperatively driven engines with the same rotation speed and rotation direction can be connected in series on a rotating shaft to form a series engine group, based on the power requirement of the generator and the output power of a single submersible piston cooperatively driven engine. The two or more submersible piston cooperatively driven engines jointly drive a rotating shaft to rotate, thereby effectively increasing the output power of the series engine group to meet the power requirement of the generator. In order to ensure the cooperative operation of two or more submersible piston cooperatively driven engines, it is necessary to ensure that the two or more engines connected in series on the same rotating shaft should have the same rotation speed and the same rotation direction, thereby ensuring that the two or more engines can drive a rotating shaft to rotate synchronously at the same frequency;

[0035] (7) Start the engine rotating disc. When starting the submersible piston generator set, first open the generator set electronic lock, then press the start button, the intelligent control system controls the motor in the start and brake controller to start, the motor first pulls the brake pad drive mechanism, so that the two brake pads are separated from the start and brake discs, releasing the clamping effect of the brake pads on the start and brake discs, then the motor pushes the start gear through the start gear connection mechanism to engage with the start and brake disc outer gear, assisting in driving the start and brake disc to rotate, and driving the engine rotating disc and the engine center shaft to rotate, so that the engine speed quickly reaches the set speed, at this time, the intelligent control system controls the start gear to separate from the start and brake discs, and turns off the motor;

[0036] (8) Drive the generator rotor winding to rotate and generate electricity. After the engine rotating disk reaches the set speed, all the submerged pistons in their respective piston cylinders continuously and stably perform cyclic reciprocating motion, so that the submerged pistons on the left and right sides of the vertical line of the engine center axis continuously generate torque difference and torque difference; at the same time, the liquid in all piston cylinders and gravity boxes continuously and regularly circulates in their respective piston cylinders and gravity boxes, so that the liquid in the piston cylinders and gravity boxes on the left and right sides of the vertical line of the engine center axis continuously generates gravity torque difference and torque difference. The torque difference and torque difference generated by the submerged pistons and the gravity torque difference and torque difference generated by the liquid continuously drive the piston cylinder and gravity box to rotate, and drive the engine rotating disk and the engine center axis to rotate. The driving wheel on the engine center axis drives the power input wheel of the multi-stage gearbox to rotate. After the multi-stage gearbox is changed in speed, the speed required by the generator is output, and the generator rotor winding is driven to rotate and generate electricity, providing users with stable and high-quality electricity.

[0037] Regarding the method of connecting the submersible piston cooperatively driven engine to drive the multi-stage gearbox and the generator, first of all, it is explained that there are two ways to install the submersible piston cooperatively driven engine on the base of the generator set, namely the vertical installation method and the parallel installation method. The installation method in which the central axis of the submersible piston cooperatively driven engine is perpendicular to the center line of the base of the generator set is the vertical installation method; the installation method in which the central axis of the submersible piston cooperatively driven engine is parallel to the center line of the base of the generator set is the parallel installation method. Under the above two installation methods, there are 6 methods for connecting and driving the submersible piston cooperatively driven engine with the multi-stage gearbox and the generator:

[0038] (1) Belt connection drive method. After accurately calculating the speed ratios among the drive pulley on the central shaft of the submerged piston cooperative drive engine, the power input pulley and power output pulley of the multi-stage gearbox, and the pulley on the generator shaft, a drive pulley of a corresponding radius is installed on the central shaft of the submerged piston cooperative drive engine, a power input pulley and a power output pulley of a corresponding radius are installed on the power input shaft and the power output shaft of the multi-stage gearbox, and a pulley of a corresponding radius is installed on the generator shaft. When the submerged piston cooperative drive engine is running, the drive pulley on the central shaft of the engine is connected to the power input pulley of the multi-stage gearbox through a belt, and drives the power input pulley of the multi-stage gearbox to rotate. After the multi-stage gearbox changes speed, the power output pulley of the multi-stage gearbox is connected to the pulley on the generator shaft through a belt, and drives the generator shaft and rotor winding to rotate to generate electricity, thereby providing electricity to users.

[0039] (2) Gear connection drive method. After accurately calculating the speed ratio of each gear, a drive gear of corresponding radius is installed on the central shaft of the submerged piston cooperative drive engine, a power input gear and a power output gear of corresponding radius are installed on the power input shaft and the power output shaft of the multi-stage gearbox respectively, and a gear of corresponding radius is installed on the generator shaft. When the submerged piston cooperative drive engine is running, the engine central shaft drive gear meshes and drives the power input gear of the multi-stage gearbox to rotate. After the multi-stage gearbox changes speed, the power output gear of the multi-stage gearbox meshes with the gear on the generator shaft, driving the generator shaft and the rotor winding to rotate to generate electricity and provide electricity to users.

[0040] (3) The connection drive method of first belt and then gear. After accurately calculating the speed ratio of each pulley and gear, a drive pulley of corresponding radius is installed on the central shaft of the submerged piston cooperative drive engine, a power input pulley of corresponding radius is installed on the power input shaft of the multi-stage gearbox, a power output gear of corresponding radius is installed on the power output shaft of the multi-stage gearbox, and a gear of corresponding radius is installed on the generator shaft. When the submerged piston cooperative drive engine is running, the engine central shaft drive pulley is connected through a belt and drives the power input pulley of the multi-stage gearbox to rotate. After the multi-stage gearbox changes speed, the power output gear of the multi-stage gearbox engages with the gear on the generator shaft, driving the generator shaft and the rotor winding to rotate to generate electricity and provide electricity to users.

[0041] (4) The connection drive method of first gear and then belt. After accurately calculating the speed ratio of each gear and pulley, a drive gear of corresponding radius is installed on the central shaft of the submerged piston cooperative drive engine, a power input gear of corresponding radius is installed on the power input shaft of the multi-stage gearbox, a power output pulley of corresponding radius is installed on the power output shaft of the multi-stage gearbox, and a pulley of corresponding radius is installed on the generator shaft. When the submerged piston cooperative drive engine is running, the engine central shaft drive gear meshes and drives the power input gear of the multi-stage gearbox to rotate. After the multi-stage gearbox changes speed, the power output pulley of the multi-stage gearbox is connected to the pulley on the generator shaft through a belt, driving the generator shaft and the rotor winding to rotate to generate electricity and provide electricity to users.

[0042] (5) Belt direct connection drive method. After accurately calculating the speed ratio between the driving pulley on the central shaft of the submerged piston cooperative drive engine and the pulley on the generator shaft, if the engine output speed is consistent with the speed required by the generator, there is no need for a multi-stage gearbox for speed change processing. The driving wheel on the central shaft of the engine directly connects and drives the driven wheel on the generator shaft and the generator rotor winding to rotate and generate electricity. A driving pulley of corresponding radius is installed on the central shaft of the submerged piston cooperative drive engine, and a pulley of corresponding radius is installed on the generator shaft. When the submerged piston cooperative drive engine is running, the engine central shaft driving pulley is connected to the pulley on the generator shaft through a belt, driving the generator shaft and the rotor winding to rotate and generate electricity, thereby providing electricity to users.

[0043] (6) Gear direct connection drive method. After accurately calculating the speed ratio between the driving gear on the central shaft of the submerged piston cooperative drive engine and the gear on the generator shaft, if the engine output speed is consistent with the speed required by the generator, there is no need for a multi-stage gearbox for speed change processing. The driving wheel on the central shaft of the engine directly connects and drives the driven wheel on the generator shaft and the generator rotor winding to rotate and generate electricity. A driving gear of corresponding radius is installed on the central shaft of the submerged piston cooperative drive engine, and a gear of corresponding radius is installed on the generator shaft. When the submerged piston cooperative drive engine is running, the engine central shaft driving gear directly engages with the gear on the generator shaft, driving the generator shaft and rotor winding to rotate and generate electricity, thereby providing electricity to users.

[0044] The present invention provides the above six connection and driving methods. Users can choose the connection and driving method they need according to the purpose and actual use requirements of the submersible piston generator set, thereby greatly improving the practicality of the submersible piston generator set.

[0045] Compared with the existing generator sets, power generation technologies and power generation methods, the present invention has the following advantages and significant effects due to the adoption of the above technical solutions:

[0046] (1) The present invention creates a submerged piston cooperatively driven power generation technology and equipment, which greatly improves the efficiency and benefits of the cooperatively driven power generation of gravity potential energy and buoyancy potential energy, and effectively improves the power generation capacity and power generation. Thus, the synergistic driving force generated by the stable, clean, and permanently usable gravity potential energy and buoyancy potential energy becomes an important driving force for power production, creating a new power generation system and a new power production method with high stability, high efficiency, high quality, high cleanliness, no resource consumption, and low construction cost.

[0047] (2) The present invention creates a piston cylinder based on a balanced structure and an unbalanced structure and an outer gravity box and an inner gravity box with opposite directions at both ends, a submerged piston, a piston motion controller, a piston fixed angle control switch, and an engine rotation direction control method, a speed control method and a power control method, thereby creating a complete set of pioneering support systems, components, equipment and systems based on a power generation system, which greatly improves the efficiency of converting gravitational potential energy and buoyancy potential energy into rotational power, effectively guarantees the power production efficiency and the stability, reliability, continuity and high quality of the submerged piston generator set, comprehensively improves the function and performance of the submerged piston generator set, and thus effectively guarantees the originality and practicality of the submerged piston generator set.

[0048] (3) The present invention creates a submersible piston generator set including a submersible piston cooperative drive engine, a multi-stage gearbox, a generator, a battery, a charging generator, and an intelligent control system. This groundbreaking generator set not only has a strong power generation capacity and complete power generation functions, but also, by creating an auxiliary power system including a multi-stage gearbox with a charging drive wheel, a charging generator and a battery, it can provide power for the control motor, intelligent control system and DC equipment of the submersible piston generator set, thereby realizing the unification of power production and self-power supply of the submersible piston generator set. Compared with the functions and performance of existing small diesel generators, gasoline generators and gas generators, the submersible piston generator set has the advantages of more comprehensive functions, more efficient operation and more convenient use.

[0049] (4) The present invention creates a power control method for a single submersible piston cooperatively driven engine, a coaxial series operation method for two or more submersible piston cooperatively driven engines with the same rotation speed and the same rotation direction, and a connection and driving method for six types of submersible piston cooperatively driven engines with a multi-stage gearbox and a generator. Therefore, it is possible to design and produce submersible piston generator sets of various powers and models, and well meet the needs of various users for submersible piston generator sets of different powers and models.

[0050] (5) The present invention creates a submersible piston cooperatively driven engine starting and braking technology and equipment. On the one hand, it greatly improves the starting and braking efficiency of the submersible piston cooperatively driven engine; on the other hand, it provides a strong guarantee for the starting, shutdown, maintenance and maintenance of the submersible piston generator set.

[0051] (6) The present invention creates an intelligent control system for a submersible piston generator set, which realizes the automation and intelligence of monitoring, control, and fault warning of the entire generator set, making the operation control and operation of the entire power generation system very simple and convenient.

[0052] (7) The submersible piston generator set only needs stable gravitational potential energy and buoyancy potential energy, and has high power generation efficiency, good stability, strong sustainability, high power quality, and low power generation system cost. Moreover, the submersible piston generator set does not need to consume any material resources during the entire life cycle of power production, does not produce any harmful emissions, and is not affected by any natural environmental changes. In addition, according to the user's requirements for the output power of the generator set, submersible piston generator sets of various powers and models can be designed and manufactured to meet the user's needs for various powers and models of generator sets. Therefore, the present invention has good novelty, creativity and practicality, and the present invention can be fully put into commercial application and industrial development, and has broad market prospects.

[0053] (8) Compared with steam turbine generator sets, diesel generator sets, gasoline generator sets and gas generator sets, these fossil energy generator sets need to burn a large amount of coal, oil and natural gas resources, produce a large amount of greenhouse gas emissions, cause environmental pollution, and the cost of electricity production is very high. The power generation process of the submersible piston generator set does not require the consumption of any fossil energy such as coal, oil, natural gas, nor does it produce any harmful substances or environmental pollution. It only requires stable gravitational potential energy and buoyancy potential energy. Therefore, the industrialization of the results of the present invention plays an important role in gradually reducing and replacing diesel generator sets, gasoline generator sets and gas generator sets, reducing greenhouse gas emissions and environmental pollution, and accelerating the realization of carbon peak and carbon neutrality goals.

[0054] (9) Compared with hydropower stations, the construction and operation of hydropower stations require a large amount of continuous water supply, the construction of dams and the flooding of a large amount of land, causing many residents to relocate, and the construction cost is very high. The power generation of hydropower stations is affected by the precipitation in the dry and wet seasons, seasonal and climate changes, and natural environmental conditions. Moreover, hydropower stations cannot be built in many areas without sufficient water sources. Submersible piston generator sets do not require a large amount of land, nor do they require a large amount of water supply, and the construction cost is low. Therefore, compared with hydropower stations that are mainly based on unstable water flow impact, submersible piston generator sets have strong advantages.

[0055] (10) Compared with wind power stations and solar power stations, these power generation methods are directly affected by weather, climate, seasons, day and night changes and natural environmental conditions, resulting in low stability of power production, low power quality, small power generation, and even impact on the surrounding ecological environment. In addition, the construction cost is high. Submersible piston generator sets are not affected by weather, climate, seasons, day and night changes and natural environmental conditions, nor will they have any impact on the surrounding ecological environment. In addition, they have good power generation stability, high power generation efficiency, good power quality, and large power generation, which will be very popular among users.

[0056] (11) Compared with small nuclear power plants, small nuclear power plants are very expensive, and the nuclear materials used for power generation are very expensive. In particular, once a nuclear power plant has a nuclear leak or nuclear explosion, it will cause great losses and impacts on the lives, property and ecological environment of the surrounding areas. During the operation of the submersible piston generator set, it does not need to consume any nuclear materials or other substances, nor does it have any harmful radiation or safety hazards. Therefore, the submersible piston generator set is a very safe power source.

[0057] (12) All technologies and intellectual property rights included in the present invention are independent intellectual property rights. The materials, components, equipment, and systems required for the industrial development of the present invention are designed and manufactured by the inventors themselves and produced by domestic manufacturers. There is no need to introduce any technology, materials, components, equipment, and systems from other countries. Therefore, there are no trade barriers to the industrial development of the present invention. Looking at the existing power generation methods, power generation technologies, and generator equipment, the present invention, as a set of subversive original technological achievements, will completely change the global energy structure and strongly promote the world energy revolution and industrial transformation after its large-scale industrial development.

DETAILED DESCRIPTION

[0065] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages, features and significant effects of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, which are only used to clearly and conveniently assist in explaining the purpose of the embodiments of the present invention.

[0066] See also Figure 1The present invention provides a submersible piston generator set, which is a small and medium power generator set, including a submersible piston cooperative driving engine, a multi-stage gearbox 19, a generator 20, an intelligent control system 21, a charging generator 26, a battery 27 and a generator set base 16. After the same amount of liquid is injected into each piston cylinder 1 and the gravity box of the submersible piston cooperative driving engine, the submersible piston 4 or the submersible piston string located in the piston cylinder 1 is in the coordinated action of the liquid buoyancy and its own gravity, and performs a cyclic reciprocating motion in each piston cylinder 1 in turn.

It is the torque differences and torque differences generated by the submerged pistons 4 or the submerged piston strings and the gravity torque differences and torque differences generated by the liquid that continuously and stably drive the piston cylinder 1 and the gravity box to rotate. , and drives the engine rotating disk and the engine center shaft 7 to rotate, the driving wheel on the engine center shaft 7 drives the power input wheel of the multi-stage gearbox 19 to rotate, and after the multi-stage gearbox 19 changes speed, the power output wheel of the multi-stage gearbox 19 outputs the speed and power required by the generator, driving the generator rotor winding to rotate and generate electricity; at the same time, the charging driving wheel of the multi-stage gearbox 19 drives the rotor winding of the charging generator 26 to rotate and generate electricity.

[0070] See also Figure 3 and Figure 4 The liquid in the piston cylinder 1 and the gravity box is used to carry the submerged piston 4 or the submerged piston string to do the buoyancy movement. The length, shape, volume, capacity of the piston cylinder 1 and the length, volume and weight of the submerged piston 4 or the submerged piston string determine the volume and weight of the liquid in the piston cylinder 1 and the gravity box. The liquid level height of the liquid injected into the piston cylinder 1 and the gravity box along the piston cylinder 1 must ensure that after the submerged piston 4 or the submerged piston string floats out of the liquid surface, the piston motion controller 5 can lock the submerged piston 4 or the submerged piston string, that is, the liquid level height of the liquid in the piston cylinder 1 is just enough to After the submersible piston 4 or the submersible piston string floats out of the liquid, the piston motion controller 5 just locks the height of the submersible piston 4 or the submersible piston string, thereby ensuring that the submersible piston 4 or the submersible piston string can perform a circular reciprocating motion along the piston cylinder 1 under the coordinated action of the liquid buoyancy and its own gravity in the piston cylinder 1; when the submersible piston cooperates with the engine to run, it is necessary to first inject an equal amount of liquid into all the piston cylinders 1 and the gravity box. The liquid injected into the piston cylinder 1 and the gravity box is clean water at room temperature. In special cases, oil, alcohol or other special liquids can also be used;

[0071] See also Figure 3 and Figure 4, a submersible piston 4 and a submersible piston string, the submersible piston 4 is the driving mechanism of the engine, which is composed of a gravity body and a closed hollow floating body, the gravity body is placed in the middle position inside the closed hollow floating body and fixed, the submersible piston 4 is designed and made into a "shuttle" shape, that is, the two ends of the submersible piston 4 are respectively designed and made into a cone, a hemispherical or a semi-ellipsoidal shape to reduce the liquid resistance of the submersible piston 4 when it moves in the liquid, two or more groups of bearing pulleys are installed on the outer walls on both sides of the submersible piston 4 along the direction of movement, each group of bearing pulleys consists of three pulleys, and a completely parallel groove-shaped, "L"-shaped or "T"-shaped piston sliding groove is installed on the inner walls on both sides of the piston cylinder 1, the submersible piston 4 is installed on two parallel piston sliding grooves, and the bearing pulleys on both sides of the submersible piston 4 are clamped in the middle of the parallel tracks of the two piston sliding grooves, so that the submersible piston 4 can slide cyclically along the parallel tracks of the piston sliding groove without leaving the piston sliding groove. In order to efficiently utilize the stable, continuous and clean energy of buoyancy potential energy and gravity potential energy, effectively convert the buoyancy potential energy and gravity potential energy into a coordinated driving force, and then convert the coordinated driving force into a rotational power, when designing and manufacturing the submerged floating piston 4, the liquid buoyancy on the submerged floating piston 4 is always greater than its own gravity, so that the submerged floating piston 4 always has the ability to float in the liquid of the piston cylinder 1. After an equal amount of liquid is injected into each piston cylinder 1 and the gravity box, the submerged floating piston 4 continuously performs a circular reciprocating motion along the parallel track of the piston sliding groove under the coordinated action of the liquid buoyancy and its own gravity, so that the submerged floating pistons 4 on the left and right sides of the vertical line of the engine center axis 7 produce a torque difference and a torque difference; at the same time, the liquid located in the piston cylinder 1 and the gravity boxes at both ends of the piston cylinder 1 continuously circulates, so that the piston cylinders on the left and right sides of the vertical line of the engine center axis 7 1 generates a gravity moment difference and a torque difference with the liquid in the gravity box. It is the torque difference and the torque difference generated by the submerged piston 4 and the gravity moment difference and the torque difference generated by the liquid that drive the piston cylinder 1 and the gravity box to rotate, and drive the engine rotating disk and the engine central axis 7 to rotate, and output power to the outside; the submerged piston string is composed of two or more independent submerged pistons 4 connected in series and tightly connected. The submerged piston string is uniformly installed on the piston sliding groove, and as a whole, under the synergistic effect of the liquid buoyancy and its own gravity, it performs a cyclic reciprocating motion along the parallel track of the piston sliding groove; the entire submerged piston string is designed and manufactured into a "shuttle shape", and the connecting parts of the two submerged pistons 4 are the same shape as the middle part of the submerged piston 4, and are tightly connected, so that the connecting parts of the two submerged pistons 4 become a smooth columnar body, so as to reduce the liquid resistance when the submerged piston string moves in the liquid. Compared with a single submersible piston 4, the submersible piston string can increase the weight of the driving mechanism, thereby increasing the torque difference and torque difference of the submersible piston string on the left and right sides of the vertical line of the engine center axis 7, and improving the speed and output power of the submersible piston cooperatively driven engine;

[0072] See also Figure 1 and Figure 2Regarding the starting and braking control system, after an equal amount of liquid is injected into each piston cylinder 1 and the gravity box, the weight of the engine rotating disk is greatly increased, and the inertia of the engine rotating disk is greatly increased. When the submersible piston generator set is started and shut down, it is necessary to provide auxiliary driving force for the starting of the engine rotating disk and effectively brake the shutdown of the engine rotating disk.

The intelligent control system 21 controls the motor to start through the motor intelligent switch. The motor first pulls the brake pad drive mechanism to make the two brake pads leave the starting and brake discs 14, releasing the clamping effect of the brake pads on the starting and brake discs 14. Then, the motor pushes the starting gear to engage with the outer edge gear of the starting and brake discs 14 through the starting gear connection mechanism, and assists in driving the starting and brake discs 14 to rotate. The starting and brake discs 14 drive the engine rotating disk and the engine center axis 7 to rotate, so that the engine speed quickly reaches the set speed. When the speed sensor of the intelligent control system 21 detects that the engine speed reaches the set speed, the intelligent control system 21 controls the motor to pull the starting gear connection mechanism so that the starting gear engages with the starting and brake discs 1 4's outer gear is separated, and the motor is turned off by controlling the motor intelligent switch; when the submersible piston generator set needs to be shut down, the brake button 23 is pressed, and the intelligent control system 21 controls the motor to start through the motor intelligent switch, and the motor pushes the brake pad drive mechanism to drive the two brake pads on the brake pad drive mechanism in a disc brake manner to slowly clamp and brake the starter and brake disc 14 until the engine rotating disc stops rotating.

[0075] See also Figure 3 and Figure 4 The piston cylinder 1 and the gravity box can be a balanced structure or an unbalanced structure. The piston cylinder 1 and the gravity box of the balanced structure mean that the thickness, length, shape, volume and capacity of each piston cylinder 1, each outer gravity box 2, and each inner gravity box 3 are the same, and the thickness and caliber of the piston cylinder 1 and the gravity box are also the same. The outer gravity box 2 and the inner gravity box 3 at both ends of the piston cylinder 1 have the same volume and capacity, and the piston cylinder 1 is perpendicular to the plane of the hub platform 9 on the outer edge of the central axis. The piston cylinder 1 and the gravity box of the balanced structure have good running stability. Figure 3It is a plan view of the construction of a piston cylinder 1 and a gravity box of a balanced structure. Under the premise of ensuring that the length, shape, volume, and capacity of each piston cylinder 1 and gravity box are exactly the same and the weight of the liquid in each piston cylinder 1 and gravity box is exactly the same, the piston cylinder 1 and gravity box can also be designed and manufactured into a piston cylinder 1 and gravity box of an unbalanced structure. The unbalanced structure of the piston cylinder 1 and gravity box means that the thickness of the two ends of the piston cylinder 1 and gravity box can be different. It can be designed as a piston cylinder 1 with a large end and a small end, and a gravity box with a large end and a small end. Moreover, the thickness and caliber of the piston cylinder 1 and the gravity box can be different. The volumes and capacities of the outer gravity box 2 and the inner gravity box 3 at both ends of the piston cylinder 1 may be different, and the plane of the piston cylinder 1 and the hub platform 9 at the outer edge of the central axis may not be perpendicular.

[0078] See also Figure 2The engine rotating disk is a rotating mechanism system and power generation system of the engine driven by the submerged pistons. It is a completely balanced rigid body composed of a rotating wheel rim 13, a starting and braking disc 14, a rotating wheel rim fixing bracket 10, a circular sheet stirrup 11, a rotating wheel rim supporting platform 12, a central axis outer edge hub platform 9, a piston cylinder 1, an outer gravity box 2, an inner gravity box 3, an equal amount of liquid in the piston cylinder 1 and the gravity box, a submerged piston 4 or a submerged piston string, a piston motion controller 5, a piston fixed angle control switch 6, and an engine central axis 7. The entire engine rotating disk will not deform or shake during rotation; after an equal amount of liquid is injected into each piston cylinder 1 and the gravity box, the submerged pistons 4 located in all piston cylinders 1 circulate back and forth in sequence under the coordinated action of the liquid buoyancy and their own gravity. The movement causes the submerged pistons 4 on the left and right sides of the vertical line of the engine center axis 7 to produce torque difference and torque difference, and causes the submerged piston 4 to apply a larger torque to the piston cylinder 1 on the side with the larger torque, thereby driving the piston cylinder 1 and the gravity box to rotate, and driving the engine rotating disk and the engine center axis 7 to rotate, and output power to the outside; at the same time, the liquid located in all the piston cylinders 1 and the gravity box circulates in their respective piston cylinders 1 and gravity boxes in turn, causing the liquid in the piston cylinders 1 and the gravity box on the left and right sides of the vertical line of the engine center axis 7 to produce a gravity moment difference and torque difference, and the liquid applies a larger torque to the piston cylinder 1 and the gravity box on the side with the larger gravity moment, and together with the submerged piston 4, drives the piston cylinder 1 and the gravity box to rotate, and drives the engine rotating disk and the engine center axis 7 to rotate, and outputs power to the outside.

[0079] See also Figure 2 , Figure 3 and Figure 4 The piston motion controller 5 is a controller that directly controls the locking and starting of the submersible piston 4 to ensure that the submersible piston 4 performs uniform and regular reciprocating motion. Each piston cylinder 1 has two piston motion controllers 5, which are respectively installed and fixed on the inner walls at both ends of the piston cylinder 1. The piston motion controller 5 at each end corresponds to one end of the submersible piston 4. When the submersible piston 4 moves from one end of the piston cylinder 1 to the other end, the piston motion controller 5 located at the other end of the piston cylinder 1 immediately and automatically locks the submersible piston 4, controlling the submersible piston 4 to stop moving. During the rotation of the engine rotating disk, when the submersible piston 4 needs to start moving, the piston motion controller 5 releases the submersible piston 4 under the control of the piston fixed angle control switch 6, and the submersible piston 4 starts to float under the action of the buoyancy of the liquid.

[0080] See also Figure 2 , Figure 3 and Figure 4, the piston fixed angle control switch 6 is a switch controller that controls the opening state of the piston motion controller 5 and allows the submerged piston 4 to start moving according to the set angle between the piston cylinder 1 and the vertical line of the engine center axis 7. Each piston cylinder 1 has two piston fixed angle control switches 6, which are respectively installed and fixed on the inner walls at both ends of the piston cylinder 1 and are integrated with the piston motion controller 5. According to the speed requirement of the submerged piston to cooperatively drive the engine, the angle between the piston cylinder 1 and the vertical line of the engine center axis 7 is set as the starting angle of the movement of the submerged piston 4, and the starting angle includes the starting angle above the horizontal plane of the engine center axis 7 and the starting angle below the horizontal plane of the engine center axis 7; when the engine rotating disk rotates in the clockwise direction, when the piston cylinder 1 rotates to the set starting angle below the horizontal plane of the engine center axis 7, the piston fixed angle control switch 6 located at the outer end of the piston cylinder 1 drives the piston motion controller 5 to release the submerged piston 4, and the submerged piston 4 located at the outer end of the piston cylinder 1 starts When the piston cylinder 1 rotates to the set starting angle above the horizontal plane of the engine central axis 7, the piston fixed angle control switch 6 located at the inner end of the piston cylinder 1 drives the piston motion controller 5 to release the submerged floating piston 4. The submerged floating piston 4 located at the inner end of the piston cylinder 1 starts to do the floating movement and quickly reaches the outer end of the piston cylinder 1. The piston motion controller 5 located at the outer end of the piston cylinder 1 immediately locks the submerged floating piston 4. The submerged floating piston 4 is locked and released cyclically and regularly, which ensures that the submerged floating piston 4 has a stable and accurate cyclic reciprocating motion cycle, and ensures that the submerged floating piston cooperates to drive the engine with a stable and accurate speed; when the engine rotating disk rotates in the counterclockwise direction, the piston fixed angle control switch 6 is controlled in the same way; the piston fixed angle control switch 6 is integratedly connected and installed with the piston motion controller 5.

[0081] See also Figure 1 The multi-stage gearbox 19 is a gearbox that accurately regulates the output speed of the submerged piston cooperative drive engine in order to meet the speed requirements of the generator 20 and the charging generator 26. The multi-stage gearbox 19 includes a power input wheel, a power input wheel shaft, a multi-stage speed gear combination, a power output wheel, a power output wheel shaft, a charging drive wheel, a charging drive wheel shaft, a speed controller, and a gearbox housing. When the submerged piston generator set is working, the output speed and output power of the submerged piston cooperative drive engine are calculated and determined, and according to the speed requirements of the generator 20 and the charging generator 26, the speed controller adjusts the speed ratio of the multi-stage gearbox 19, so that the output speed of the multi-stage gearbox 19 meets the speed requirements of the generator 20 and the charging generator 26; the multi-stage gearbox 19 is installed and fixed on the base of the generator set.

[0082] See also Figure 1 and Figure 2, explain in detail the power generation method of the submersible piston generator set. The power generation method of the submersible piston generator set is as follows:

[0083] (1) Inject an equal amount of liquid. Inject an equal amount of liquid into each piston cylinder 1 and the gravity box to ensure that each piston cylinder 1 and the gravity box are filled with the same weight of liquid, so that each piston cylinder 1 and the gravity box have the same weight and the engine rotating disk remains in a completely balanced state; because the liquid buoyancy exerted on the submerged piston 4 is always greater than its own gravity, the submerged piston 4 always has the ability to float in the piston cylinder 1 injected with liquid.

[0084] (2) The rotation direction of the engine rotating disk is controlled by the direction indicated by the external gravity box 2. When all the external gravity boxes 2 are installed in the clockwise direction, the submerged piston 4 in the piston cylinder 1 only makes a circular reciprocating motion along the piston cylinder 1 and cannot change the rotation direction of the engine rotating disk; at the same time, the liquid in the external gravity box 2 and the piston cylinder 1 on the left side of the vertical line of the engine center axis 7 always flows to the internal gravity box 3, so that the force arm of all the piston cylinders 1 on the left side of the vertical line of the engine center axis 7 and the center of mass of the liquid in the gravity box is reduced. Since the weight of each piston cylinder 1 and the liquid in the gravity box is the same and fixed, the vector sum of the gravitational moment of all the piston cylinders 1 on the left side of the vertical line of the engine center axis 7 and the center of mass of the liquid in the gravity box is reduced; at the same time, the liquid in the internal gravity box 3 and the piston cylinder 1 on the right side of the vertical line of the engine center axis 7 always flows to the external gravity box 3, so that all the piston cylinders 1 on the right side of the vertical line of the engine center axis 7 and the center of mass of the liquid in the gravity box As the force arm increases, the vector sum of the gravity moments of all piston cylinders 1 and the mass center of the liquid in the gravity box increases, which makes the gravity moment of the piston cylinder 1 on the right side of the vertical line of the engine center axis 7 and the mass center of the liquid in the gravity box much greater than the gravity moment of the piston cylinder 1 on the left side and the mass center of the liquid in the gravity box. Therefore, the piston cylinders 1 on the left and right sides of the vertical line of the engine center axis 7 and the mass center of the liquid in the gravity box produce gravity moment difference and torque difference. It is this gravity moment difference and torque difference that makes the liquid exert a greater torque on the side with a larger gravity moment, that is, all piston cylinders 1 and the outer gravity box 2 on the right side of the vertical line of the engine center axis 7, thereby driving the piston cylinder 1 and the gravity box to rotate in the clockwise direction, and driving the engine disk and the engine center axis 7 to rotate in the clockwise direction; conversely, when all the outer gravity boxes 2 are installed in the counterclockwise direction, the engine rotating disk and the engine center axis 7 rotate in the counterclockwise direction. Therefore, the direction indicated by the outer gravity box 2 is the rotation direction of the engine rotating disk and the engine center axis 7.

[0085] (3) Control the power generation of the engine. When designing and manufacturing the submersible piston 4, the liquid buoyancy of the submersible piston 4 is always greater than its own gravity. The submersible piston 4 always has a tendency to float upward in the liquid of the piston cylinder 1. Each submersible piston 4 is precisely controlled by the piston motion controller 5 and the piston fixed angle control switch 6. Under the coordinated action of the liquid buoyancy and its own gravity, all the submersible pistons 4 perform uniform and regular cyclic reciprocating motion in their respective piston cylinders 1. When the engine rotating disk rotates clockwise, when the submersible piston 4 located below the horizontal plane of the engine central axis 7 approaches the right side of the vertical line at the lower part of the engine central axis 7, the piston fixed angle control switch 6 drives the piston motion controller 5 to release the submersible piston 4, and the submersible piston 4 quickly moves toward the direction of the hub platform 9 on the outer edge of the central axis. When the submersible piston 4 moves to the end of the hub platform 9 on the outer edge of the central axis, the piston motion controller 5 automatically locks the submersible piston 4, so that the force arm of the submersible piston 4 is reduced, and the torque of the submersible piston 4 is also reduced. As the engine rotating disk continues to rotate, the position All the submerged floating pistons 4 on the left side of the vertical line of the engine central axis 7 are locked at the end of the hub platform 9 on the outer edge of the central axis, so that the moment vector sum of all the submerged floating pistons 4 is minimized; at the same time, when the submerged floating piston 4 located above the horizontal plane of the engine central axis 7 approaches the left side of the upper vertical line of the engine central axis 7, the piston fixed angle control switch 6 drives the piston motion controller 5 to release the submerged floating piston 4, and the submerged floating piston 4 quickly moves toward the rotating wheel rim 13. When the submerged floating piston 4 moves to the end of the rotating wheel rim 13, the piston motion controller 5 automatically locks the submerged floating piston 4, so that the force arm of the submerged floating piston 4 increases. The torque of the submerged piston 4 is also increased. With the continuous rotation of the engine rotating disk, all the submerged pistons 4 located on the right side of the vertical line of the engine center axis 7 are locked at the end of the rotating wheel ring 13, so that the moment vector sum of all the submerged pistons 4 is maximized, which results in the maximum torque difference and torque difference between the submerged pistons 4 on the left and right sides of the vertical line of the engine center axis 7. It is the existence of this torque difference and torque difference that causes the submerged piston 4 to apply a greater torque to the piston cylinder 1 on the side with a larger torque, thereby driving the piston cylinder 1 and the gravity box to rotate evenly and regularly, and driving the engine to rotate. The rotating disk and the engine center axis 7 rotate to output power to the outside; at the same time, during the continuous rotation of the engine rotating disk, the liquid in each piston cylinder 1 and the gravity box circulates continuously and regularly, so that the piston cylinder 1 on the left and right sides of the vertical line of the engine center axis 7 and the liquid in the gravity box produce a gravity moment difference and a torque difference. The gravity moment difference and torque difference produced by the liquid cause the liquid to apply a greater torque to the piston cylinder 1 and the gravity box on the side with a larger torque, driving the piston cylinder 1 and the gravity box to rotate, and driving the engine rotating disk and the engine center axis 7 to rotate, and output power to the outside.It can be seen that the power generated by the submerged piston cooperatively driving the engine is the vector sum of the rotational torque of the submerged piston 4 and the rotational torque of the piston cylinder 1 and the liquid in the gravity box; when the engine rotating disk rotates counterclockwise, the same power output can be obtained;.

[0086] (4) Control the engine speed. The speed of the engine driven by the submersible piston is determined by the number, length, volume, capacity and liquid weight of the piston cylinder 1 and the gravity box, the volume and weight of the submersible piston 4, and the starting angle of the submersible piston 4 when the submersible piston 4 moves. After the number, length, volume, capacity and liquid weight of the piston cylinder 1 and the gravity box and the volume and weight of the submersible piston 4 are determined, the engine speed can be accurately controlled by controlling the starting angle of the submersible piston 4. The specific engine speed control method is as follows:

[0087] Calculate the one-way running time of the submersible piston 4 in the piston cylinder 1: Since the liquid buoyancy of the submersible piston 4 is always greater than its own weight, after the volume and weight of the submersible piston 4, the effective length of the submersible piston 4 in the piston cylinder 1 for cyclic reciprocating motion, and the liquid level height of the piston cylinder 1 and the liquid in the gravity box are determined, the liquid buoyancy and its own weight of the submersible piston 4 can be accurately calculated first, and then, after calculating the resistance of the submersible piston 4 in the liquid, the time required for the submersible piston 4 to move from one end of the piston cylinder 1 to the other end can be accurately calculated;

[0088] Control the engine speed: according to the one-way running time of the submerged piston 4 in the piston cylinder 1, set the angle between the piston cylinder 1 and the vertical line of the engine center axis 7 as the starting angle for the submerged piston 4 to start moving. When the engine rotating disk rotates clockwise, when the piston cylinder 1 located on the right side of the vertical line of the engine center axis 7 rotates to any angle below the horizontal plane of the engine center axis 7, the piston fixed angle control switch 6 drives the piston movement controller 5 to release the submerged piston 4, and the submerged piston 4 will float upward from the rotating wheel rim 13 end and quickly move toward the hub platform on the outer edge of the center axis. 9, at this time, the torque of the submerged piston 4 will decrease, so that the speed of the engine rotating disk will decrease; at the same time, when the piston cylinder 1 located on the left side of the vertical line of the engine central axis 7 rotates to any angle above the horizontal plane of the engine central axis 7, the piston fixed angle control switch 6 drives the piston movement controller 5 to release the submerged piston 4, and the submerged piston 4 will float upward from the end of the hub platform 9 on the outer edge of the central axis, and quickly move toward the rotating wheel rim 13. At this time, the torque of the submerged piston 4 will increase, forming an opposite torsion force, so that the speed of the engine rotating disk will decrease. It can be seen that when the starting angle of the submerged piston 4 movement is larger, the submerged piston 4 is released to allow the submerged piston 4 to start moving, and the speed of the engine will be smaller. When the starting angle of the submerged piston 4 movement is smaller, the submerged piston 4 is released to allow the submerged piston 4 to start moving, and the speed of the engine will be greater. Therefore, according to the speed requirement of the generator 20 and the speed ratio of the multi-stage gearbox 19, the starting angle of the movement of the submerged piston 4 can be calculated and determined. According to the determined starting angle of the movement of the submerged piston 4, the movement of the submerged piston 4 can be controlled by the piston fixed angle control switch 6 and the piston movement controller 5, so that the reciprocating motion cycle of the submerged piston 4 can be accurately controlled, thereby controlling the speed of the engine to meet the requirements of the generator 20 for the engine output speed; when the engine rotating disk rotates in the counterclockwise direction, the engine speed control method is the same as the above method;

[0089] (5) Calculate and determine the power of the engine. The power of the submerged piston cooperative drive engine is the sum of the power generated by the reciprocating motion of all the submerged pistons 4 and the power generated by the circulating flow of the liquid in all the piston cylinders and the gravity box. The specific power calculation method is as follows:

[0090] For the submersible piston 4, according to the torque calculation formula M 活 =F×L, where M 活 is the moment of the center of mass of the submerged piston 4, F is the gravity of the center of mass of the submerged piston 4, L is the vector distance between the center of mass of the submerged piston 4 and the vertical line of the engine center axis 7, according to the engine power generation method, the torque difference ΔM generated by the submerged piston 4 on the left and right sides of the vertical line of the engine center axis 7 活 for: Among them, F 活is the gravity of the mass center of the submerged piston 4 in each piston cylinder 1. The gravity of the mass center of the submerged piston 4 in each piston cylinder 1 is equal. 右i is the vector distance between the mass center of the submerged piston 4 in the i-th piston cylinder 1 on the right side of the vertical line of the engine center axis 7 and the vertical line of the engine center axis 7, L 左i is the vector distance between the mass center of the submerged piston 4 in the i-th piston cylinder 1 on the left side of the vertical line of the engine center axis 7 and the vertical line of the engine center axis 7, n is the number of the submerged piston 4 on one side of the vertical line of the engine center axis 7, after the number of piston cylinders 1, the effective length of the reciprocating motion of the submerged piston 4 in the piston cylinder 1, and the volume and weight of the submerged piston 4 are determined, the torque difference between the mass centers of the submerged piston 4 in the piston cylinder 1 on the left and right sides of the vertical line of the engine center axis 7 can be calculated, and the engine speed can be determined according to the engine speed control method, and according to the engine power calculation formula P 活 =ΔM 活 ×N / 9549, where P 活 is the power generated by the cyclic motion of the submersible piston 4, N is the engine speed, and the engine power driven by the submersible piston 4 can be calculated by the engine power calculation formula;

[0091] For the piston cylinder 1 and the liquid in the gravity box, according to the torque calculation formula M 液 =F×L, where M 液 is the gravity moment of the piston cylinder 1 and the center of mass of the liquid in the gravity box, F is the gravity of the center of mass of the liquid in the piston cylinder 1 and the gravity box, and L is the vector distance between the center of mass of the liquid in the piston cylinder 1 and the gravity box and the vertical line of the engine center axis 7. When all the outer gravity boxes 2 rotate in the clockwise direction, the liquid in the outer gravity box 2 and the piston cylinder 1 on the left side of the vertical line of the engine center axis 7 always flows to the inner gravity box 3, so that the vector distance between the center of mass of the liquid in the piston cylinder 1 and the gravity box on the left side of the engine center axis 7 and the vertical line of the engine center axis 7 is reduced, and the gravity moment of the center of mass of the liquid is also reduced; at the same time, the liquid in the inner gravity box 3 and the piston cylinder 1 on the right side of the vertical line of the engine center axis 7 always flows to the outer gravity box 3, so that the vector distance between the center of mass of the liquid in the piston cylinder 1 and the gravity box on the right side of the engine center axis 7 and the vertical line of the engine center axis 7 is increased, and the gravity moment of the center of mass of the liquid is also increased, which causes a gravity moment difference between the liquid in the piston cylinder 1 and the gravity box on the left and right sides of the vertical line of the engine center axis 7, that is, Among them, ΔM 液 is the gravity moment difference between the piston cylinder 1 and the center of mass of the liquid in the gravity box on both sides of the vertical line of the engine central axis 7, F 液 is the gravity of the center of mass of each piston cylinder 1 and the liquid in the gravity box. The volume and weight of the liquid in each piston cylinder 1 and the gravity box are the same and fixed, so the gravity of the center of mass of the liquid is also equal. L 右iis the vector distance between the i-th piston cylinder 1 on the right side of the vertical line of the engine center axis 7 and the center of mass of the liquid in the gravity box and the vertical line of the engine center axis 7, L 左i is the vector distance between the i-th piston cylinder 1 on the left side of the vertical line of the engine center axis 7 and the center mass of the liquid in the gravity box and the vertical line of the engine center axis 7, n is the number of piston cylinders 1 on one side of the vertical line of the engine center axis 7, after the number, length, shape structure, volume of the piston cylinder 1 and the gravity box and the weight of the liquid in the piston cylinder 1 and the gravity box are determined, the gravity moment difference between the piston cylinder 1 and the center mass of the liquid in the gravity box on the left and right sides of the vertical line of the engine center axis 7 can be calculated, according to the engine power calculation formula P 液 =ΔM 液 ×N / 9549, where P 液 is the power generated by the circulation of the liquid in the piston cylinder 1 and the gravity box, N is the engine speed, and the engine speed can be determined according to the engine speed control method. Therefore, the power generated by the circulation of the liquid in the piston cylinder 1 and the gravity box can be calculated by the engine power calculation formula. Therefore, the power P of the engine driven by the submerged piston is P 活 +P 液 ; When all the external gravity boxes rotate counterclockwise, only the engine rotating disk rotates counterclockwise, and the engine power is the same;

[0092] (6) Increasing the output power of the engine by coaxial series operation of the submerged piston cooperatively driven engine. When the output power of a submerged piston cooperatively driven engine cannot meet the power requirement of the generator 20, two or more submerged piston cooperatively driven engines with the same rotation speed and the same rotation direction can be connected in series on a rotating shaft to form a series engine group, based on the power requirement of the generator and the output power of a single submerged piston cooperatively driven engine. The two or more submerged piston cooperatively driven engines jointly drive a rotating shaft to rotate, thereby effectively increasing the output power of the series engine group to meet the power requirement of the generator 20. In order to ensure the cooperative operation of two or more submerged piston cooperatively driven engines, it is necessary to ensure that the two or more engines connected in series on the same rotating shaft should have the same rotation speed and the same rotation direction, thereby ensuring that the two or more engines can drive a rotating shaft to rotate synchronously at the same frequency;

[0093] (7) Start the engine rotating disk. When the submersible piston generator set is started, the generator set electronic lock 24 is turned on, the start button 22 is pressed, and the intelligent control system 21 controls the motor in the start and brake controller 17 to start. The motor first pulls the brake pad drive mechanism, so that the two brake pads on the brake pad drive mechanism are separated from the start and brake disk 14. Then, the motor pushes the start gear to engage with the outer gear of the start and brake disk 14 through the start gear connection mechanism, and assists in driving the start and brake disk 14 to rotate, driving the engine rotating disk and the engine center shaft 7 to rotate, so that the engine speed quickly reaches the set speed. At this time, the intelligent control system 21 controls the start gear to separate from the start and brake disk 14, and turns off the motor;

[0094] (8) Drive the generator rotor winding to rotate and generate electricity. After the engine rotating disk reaches the set speed, all the submerged pistons 4 continuously perform cyclic reciprocating motion in their respective piston cylinders 1, so that the submerged pistons 4 on the left and right sides of the vertical line of the engine center axis 7 continuously generate torque difference and torque difference; at the same time, the liquid in all the piston cylinders 1 and the gravity box continuously and regularly circulates in their respective piston cylinders 1 and the gravity box, so that the liquid in the piston cylinders 1 and the gravity box on the left and right sides of the vertical line of the engine center axis 7 continuously generates gravity moment difference and torque difference. The torque difference and torque difference generated by the submerged pistons and the gravity moment difference and torque difference generated by the liquid continuously and stably drive the piston cylinder 1 and the gravity box to rotate, and drive the engine rotating disk and the engine center axis 7 to rotate. The driving wheel on the engine center axis 7 drives the power input wheel of the multi-stage gearbox 19 to rotate. After the multi-stage gearbox 19 changes speed, the power output wheel of the multi-stage gearbox 19 outputs the speed and power required by the generator 20, drives the rotor winding of the generator 20 to rotate and generate electricity, and provides stable and high-quality electricity for users.

[0095] See also Figure 1 , and the method of connecting the submersible piston cooperative driving engine to drive the multi-stage gearbox 19 and the generator 20 is described in detail.

[0103] See also Figure 1, further illustrating the working process and technical effects of the submersible piston generator set. After an equal amount of liquid is injected into each piston cylinder 1 and the gravity box, when the submersible piston generator set needs to be started, first open the generator set electronic lock 24, then press the start button 22, the intelligent control system 21 controls the motor to start through the motor intelligent switch, the motor first pulls the brake pad drive mechanism, so that the two brake pads on the brake pad drive mechanism leave the starting and brake disc 14, and release the clamping effect of the brake pad on the starting and brake disc 14, then the motor pushes the starting gear through the starting gear connection mechanism to engage with the outer edge gear of the starting and brake disc 14, and assists in driving the starting and brake disc 14 to rotate, and the starting and brake disc 14 drives the engine rotating disc and the engine center shaft 7 to rotate, so that the engine speed quickly reaches the set Speed, when the speed sensor of the intelligent control system 21 detects that the engine speed reaches the set speed, the intelligent control system 21 controls the motor to pull the starting gear connection mechanism, so that the starting gear is separated from the outer gear of the starting and brake disc 14, and controls the motor to be turned off through the motor intelligent switch; then, all the submerged pistons 4, under the coordinated action of the liquid buoyancy and their own gravity, and under the control of the piston motion controller 5 and the piston fixed angle control switch 6, continuously reciprocate along the piston cylinder 1, so that the submerged pistons 4 on the left and right sides of the vertical line of the engine center axis 7 continue to generate torque difference and torque difference; at the same time, all the liquids in the piston cylinder 1 and the gravity box continuously circulate in the piston cylinder 1 and the gravity box. The piston cylinder 1 on the left and right sides of the vertical line of the engine center axis 7 and the liquid in the gravity box continuously generate gravity moment difference and torque difference.

There is no need to use unstable natural forces such as wind, river water, lake water, waves, tides, geothermal heat, and solar energy. It is not affected by changes in the natural environment. It only needs to rely on the synergistic driving force generated by gravitational potential energy and buoyancy energy to stably, efficiently, and continuously produce and output high-quality electricity. ;

The gravity box located at the rotating wheel rim end is the outer gravity box, the piston cylinder end located at the rotating wheel rim end is the outer end, the gravity box located at the hub platform end of the outer edge of the central axis is the inner gravity box, and the piston cylinder end located at the hub platform end of the outer edge of the central axis is the inner end. The outer gravity boxes at both ends of the piston cylinder are in opposite directions to the inner gravity boxes, and the piston cylinder and the gravity boxes at both ends are through-connected. The liquid can flow freely between the piston cylinder and the gravity boxes at both ends without seeping outward. Leakage, the length, shape, volume and capacity of each piston cylinder, outer gravity box and inner gravity box are exactly the same, the weight of the liquid in each piston cylinder and the gravity boxes at both ends is also exactly the same, and each piston cylinder and gravity box are evenly distributed in their rotation planes, ensuring that the engine rotating disk is completely balanced, a piston sliding groove parallel to each other is installed on the inner wall on both sides of each piston cylinder, and the submersible piston or submersible piston string performs a cyclic reciprocating motion under the constraint of the two parallel piston sliding grooves, and a piston motion controller and a piston fixed angle control switch are installed and integrated at the ends of the piston cylinder to control the locking and starting of the submersible piston or the submersible piston string; The liquid in the piston cylinder and the gravity box is used to carry the submerged piston or the submerged piston string to do the buoyancy movement. The length, shape, volume, capacity of the piston cylinder and the length, volume and weight of the submerged piston or the submerged piston string determine the volume and weight of the liquid in the piston cylinder and the gravity box. The liquid level of the liquid injected into the piston cylinder and the gravity box along the piston cylinder must ensure that after the submerged piston or the submerged piston string floats out of the liquid surface, the piston motion controller can lock the submerged piston or the submerged piston string, thereby ensuring that the submerged piston or the submerged piston string can perform a cyclic reciprocating motion along the piston cylinder under the synergistic effect of the buoyancy of the liquid in the piston cylinder and its own gravity. When the submerged piston cooperates with the engine to drive the engine to run, it is necessary to first inject an equal amount of liquid into all the piston cylinders and the gravity box. The liquid injected into the piston cylinder and the gravity box is clean water at room temperature. In special circumstances, oil, alcohol or other special liquids can also be used. The submersible piston and submersible piston string are the driving mechanism of the engine, which are composed of a gravity body and a closed hollow float. The gravity body is placed in the middle position of the closed hollow float and fixed. The submersible piston is designed and made into a "shuttle" shape, that is, the two ends of the submersible piston are respectively designed and made into a cone, a hemispherical or a semi-ellipsoidal shape to reduce the liquid resistance of the submersible piston when it moves in the liquid. Two or more groups of bearing pulleys are installed on the outer walls of both sides of the submersible piston along the direction of movement, and each group of bearing pulleys consists of three pulleys. A completely parallel groove-shaped, "L"-shaped or "T"-shaped piston sliding groove is installed on the inner walls of both sides of the piston cylinder. The submersible piston is installed On the two parallel piston sliding grooves, the bearing pulleys on both sides of the submerged piston are clamped in the middle of the parallel tracks of the two piston sliding grooves, so that the submerged piston can slide cyclically along the parallel tracks of the piston sliding grooves without leaving the piston sliding grooves. When designing and manufacturing the submerged piston, the liquid buoyancy of the submerged piston is always greater than its own gravity, so that the submerged piston always has the ability to float in the liquid of the piston cylinder. After the same amount of liquid is injected into each piston cylinder and the gravity box, the submerged piston continuously performs cyclic reciprocating motion along the parallel tracks of the piston sliding grooves under the coordinated action of the liquid buoyancy and its own gravity, so that the central axis of the engine is vertically supported. The submerged pistons on the left and right sides of the straight line generate torque difference and torque difference. At the same time, the liquid located in the piston cylinder and the gravity boxes at both ends of the piston cylinder continuously circulates, causing the liquid in the piston cylinder and the gravity box on the left and right sides of the vertical line of the engine center axis to generate gravity torque difference and torque difference. It is the torque difference and torque difference generated by the submerged piston and the gravity torque difference and torque difference generated by the liquid that continuously drive the piston cylinder and the gravity box to rotate, and drive the engine rotating plate and the engine center axis to rotate, and output power to the outside. The submerged piston string is composed of two or more independent submerged pistons connected in series and tightly connected. The submerged piston string is uniformly installed on the piston sliding groove and acts as a whole. The submersible piston string is designed and manufactured into a "shuttle shape", and the two submersible piston connecting parts are in the same shape as the middle part of the submersible piston, and are tightly connected, so that the two submersible piston connecting parts become a smooth columnar body, so as to reduce the liquid resistance of the submersible piston string when it moves in the liquid. Compared with a single submersible piston, the submersible piston string can increase the weight of the driving mechanism, thereby increasing the torque difference and torque difference of the submersible piston strings on the left and right sides of the vertical line of the engine central axis, and improving the speed and output power of the engine driven by the submersible pistons in cooperation; The starting and braking system is a control system for controlling the starting and braking of the engine rotating disk, including a starting and braking controller and a starting and braking disk. The starting and braking controller includes a motor, a motor intelligent switch, a starting gear, a starting gear connecting mechanism, a brake pad, a brake pad driving mechanism, a starting button, a brake button and a generator set electronic lock.

When the submersible piston generator set needs to be started, the electronic lock of the generator set is opened, and the start button is pressed. The intelligent control system starts the motor by controlling the intelligent switch of the motor of the starting and braking controller. The motor first pulls the brake pad drive mechanism, so that the two brake pads on the brake pad drive mechanism are separated from the starting and braking discs, releasing the brake pads from the starting The motor then pushes the starting gear through the starting gear connection mechanism to engage with the outer gear of the starting and brake disc, and assists in driving the starting and brake disc to rotate. The starting and brake discs drive the engine rotating disc and the engine center axis to rotate, so that the engine speed quickly reaches the set speed. When the speed sensor of the intelligent control system detects that the engine speed reaches the set speed, the intelligent control system controls the motor of the starting and brake controller to pull the starting gear connection mechanism, so that the starting gear is separated from the outer gear of the starting and brake disc, and controls the motor to shut down through the motor intelligent switch. When the submersible piston generator set needs to stop, press the brake Button, the intelligent control system starts the motor by controlling the motor intelligent switch of the starting and braking controller. The motor pushes the brake pad drive mechanism, and drives the two brake pads on the brake pad drive mechanism in a disc braking manner to slowly clamp and brake the starting and braking discs until the engine rotating disc stops rotating. At this time, when the speed sensor of the intelligent control system detects that the engine stops rotating, the intelligent control system controls the two brake pads to continue to clamp the starting and braking discs, and controls the motor to be turned off through the motor intelligent switch. Finally, the generator set electronic lock is locked.

8. The submersible piston generator set according to claim 2, characterized in that: The engine rotating disk is a rotating mechanism system and power generation system of the engine driven by the submerged pistons. It is a completely balanced rigid body composed of a rotating wheel rim, a starting and braking disc, a rotating wheel rim fixing bracket, a circular sheet stirrup, a rotating wheel rim supporting platform, a hub platform at the outer edge of the central axis, a piston cylinder, an outer gravity box, an inner gravity box, equal amounts of liquid in the piston cylinder and the gravity box, a submerged piston or a submerged piston string, a piston motion controller, a piston fixed angle control switch, and an engine central axis. The entire engine rotating disk will not deform or shake during rotation. After an equal amount of liquid is injected into each piston cylinder and the gravity box, the submerged pistons in all piston cylinders perform cyclic reciprocating motion in turn under the coordinated action of the liquid buoyancy and their own gravity. This causes the submerged pistons on the left and right sides of the vertical line of the engine's central axis to produce torque differences and torque differences, and causes the submerged piston to apply a greater torque to the piston cylinder on the side with the greater torque, thereby driving the piston cylinder and the gravity box to rotate, and driving the engine rotating disk and the engine's central axis to rotate, and outputting power to the outside. At the same time, the liquid in all the piston cylinders and gravity boxes circulates in their respective piston cylinders and gravity boxes in turn, causing the liquid in the piston cylinders and gravity boxes on the left and right sides of the vertical line of the engine's central axis to produce a gravity moment difference and torque difference, and the liquid applies a greater torque to the piston cylinder and gravity box on the side with the greater gravity moment, and together with the submerged piston drives the piston cylinder and gravity box to rotate, and drives the engine rotating disk and the engine's central axis to rotate, and outputs power to the outside.

The submersible piston generator set according to claim 2, characterized in that: The piston motion controller is a controller that directly controls the locking and starting of the submersible piston, ensuring that the submersible piston performs uniform and regular reciprocating motion. Each piston cylinder has two piston motion controllers, which are respectively installed and fixed on the inner walls at both ends of the piston cylinder. Each piston motion controller corresponds to one end of the submersible piston. When the submersible piston moves from one end of the piston cylinder to the other end, the piston motion controller located at the other end of the piston cylinder immediately and automatically locks the submersible piston and controls the submersible piston to stop moving. During the rotation of the engine rotating disk, when the submersible piston needs to start moving, the piston motion controller releases the submersible piston under the control of the piston fixed angle control switch, and the submersible piston starts to float under the action of the buoyancy of the liquid.

10.

The starting angle includes the starting angle above the horizontal plane of the engine center axis and the starting angle below the horizontal plane of the engine center axis. When the engine rotating disk rotates in a clockwise direction, when the piston cylinder rotates to the set starting angle below the horizontal plane of the engine center axis, the piston fixed angle control switch located at the outer end of the piston cylinder drives the piston movement controller to release the submerged piston, and the submerged piston located at the outer end of the piston cylinder opens. When the piston is rotated counterclockwise, the piston fixed angle control switch is controlled in the same way, and the piston fixed angle control switch is integrated with the piston motion controller and connected to the piston motion controller.

The multi-stage gearbox is installed and fixed on the base of the generator set.

12. A method for generating electricity using the submersible piston generator set according to any one of claims 1 to 11, characterized in that: The specific power generation method is as follows: (1) Inject an equal amount of liquid into each piston cylinder and gravity box to ensure that each piston cylinder and gravity box are filled with the same weight of liquid, so that each piston cylinder and gravity box have the same weight and the engine rotating disk remains in a completely balanced state. Since the liquid buoyancy of the submerged piston is always greater than its own gravity, the submerged piston always has the ability to float upward in the piston cylinder injected with liquid; (2) The rotation direction of the engine rotating disk is controlled by the direction indicated by the external gravity box. When all the external gravity boxes are installed in the clockwise direction, the submerged piston in the piston cylinder only makes a circular reciprocating motion along the piston cylinder and cannot change the rotation direction of the engine rotating disk. At the same time, the liquid in the external gravity box and the piston cylinder on the left side of the vertical line of the engine center axis always flows to the internal gravity box, so that the force arm of the center of mass of the liquid in all the gravity boxes and the piston cylinder on the left side of the vertical line of the engine center axis is reduced. Since the weight of the liquid in each gravity box and the piston cylinder is the same and fixed, the sum of the gravity moment vectors of the center of mass of the liquid in all the gravity boxes and the piston cylinder on the left side of the vertical line of the engine center axis is reduced. At the same time, the liquid in the internal gravity box and the piston cylinder on the right side of the vertical line of the engine center axis always flows to the external gravity box, so that the force arm of the center of mass of the liquid in all the gravity boxes and the piston cylinder on the right side of the vertical line of the engine center axis is increased. The vector sum of the gravity moments of the liquid mass center of all gravity boxes and the piston cylinder on the right side of the vertical line of the engine center axis increases, which makes the vector sum of the gravity moments of the liquid mass center of all gravity boxes and the piston cylinder on the right side of the vertical line of the engine center axis greater than the vector sum of the gravity moments of the liquid mass center of all gravity boxes and the piston cylinder on the left side, so that the gravity boxes on the left and right sides of the vertical line of the engine center axis and the liquid mass center of the piston cylinder produce gravity moment difference and torque difference. It is this gravity moment difference and torque difference that makes the liquid exert a greater torque on the side with a larger gravity moment, that is, the piston cylinder and the outer gravity box on the right side of the engine center axis, thereby driving the piston cylinder and the gravity box to rotate in the clockwise direction, and driving the engine disk and the engine center axis to rotate in the clockwise direction. Conversely, when all the outer gravity boxes are installed in the counterclockwise direction, the engine rotating disk and the engine center axis rotate in the counterclockwise direction. Therefore, the direction indicated by the outer gravity box is the rotation direction of the engine rotating disk and the engine center axis. (3) Control the power generation of the engine. When designing and manufacturing the submersible piston, the liquid buoyancy of the submersible piston is always greater than its own gravity, so that the submersible piston always has the ability to float in the liquid in the piston cylinder. When the engine rotating disk rotates in a clockwise direction, when the submersible piston located on the right side below the horizontal plane of the engine center axis approaches the right side of the vertical line at the lower part of the engine center axis, the piston fixed angle control switch drives the piston motion controller to release the submersible piston. The submersible piston located at the rotating wheel rim end moves rapidly toward the hub platform at the outer edge of the center axis under the action of the liquid buoyancy. When the submersible piston reaches the hub platform at the outer edge of the center axis, the piston motion controller automatically locks the submersible piston, so that the submersible piston can float upward. The force arm of the floating piston is reduced, which also reduces the torque of the submerged floating piston. As the engine rotating disk continues to rotate, all the submerged floating pistons on the left side of the vertical line of the engine center axis are locked at the end of the hub platform on the outer edge of the center axis, so that the moment vector sum of all the submerged floating pistons on the left side of the vertical line of the engine center axis is minimized. At the same time, when the submerged floating piston on the left side above the horizontal plane of the engine center axis approaches the left side of the upper vertical line of the engine center axis, the piston fixed angle control switch drives the piston motion controller to release the submerged floating piston. The submerged floating piston on the end of the hub platform on the outer edge of the center axis moves rapidly toward the rotating wheel rim under the action of liquid buoyancy. When the submerged floating piston reaches the end of the rotating wheel rim, the piston motion controller automatically locks the submerged floating piston. The plug increases the force arm of the submerged piston and also increases the torque of the submerged piston. As the engine rotating disk continues to rotate, all the submerged pistons on the right side of the vertical line of the engine central axis are locked at the rotating wheel rim end, so that the moment vector sum of all the submerged pistons on the right side of the vertical line of the engine central axis is the largest. This creates the largest torque difference and torque difference between the submerged pistons on the left and right sides of the vertical line of the engine central axis. It is the continued existence of this torque difference and torque difference that causes the submerged piston to apply a greater torque to the piston cylinder on the side with a larger torque, thereby driving the piston cylinder and the gravity box to rotate evenly and regularly, and driving the engine rotating disk and the engine central axis to rotate, outputting power to the outside, and at the same time, in the engine During the continuous rotation of the engine rotating disk, the liquid in each piston cylinder and gravity box circulates continuously and regularly, causing the liquid in the piston cylinders and gravity boxes on the left and right sides of the vertical line of the engine central axis to produce gravity moment difference and torque difference. This gravity moment difference and torque difference causes the liquid to apply a greater torque to the piston cylinder and gravity box on the side with greater torque, driving the piston cylinder and gravity box to rotate, and driving the engine rotating disk and the engine central axis to rotate, outputting power to the outside. It can be seen that the power generated by the submerged piston cooperatively driving the engine is the vector sum of the rotational torque of the submerged piston and the rotational torque of the liquid in the piston cylinder and gravity box. When the engine rotating disk rotates counterclockwise, the same power output can be obtained; (4) Controlling the speed of the engine. The speed of the engine driven by the submersible piston is determined by the number, length, shape, volume, capacity and weight of the liquid in the piston cylinder and the gravity box, the volume and weight of the submersible piston, and the starting angle when the submersible piston starts to move. After the number, length, shape, volume, capacity and weight of the liquid in the piston cylinder and the gravity box and the volume and weight of the submersible piston are determined, the speed of the engine can be accurately controlled by controlling the starting angle when the submersible piston starts to move. The specific engine speed control method is as follows: Calculate the one-way running time of the submersible piston in the piston cylinder. Since the liquid buoyancy of the submersible piston is always greater than its own weight, after the volume and weight of the submersible piston, the effective length of the submersible piston in the piston cylinder for cyclic reciprocating motion, and the liquid level height of the piston cylinder and the liquid in the gravity box are determined, the liquid buoyancy and its own weight of the submersible piston can be accurately calculated first. Then, after calculating the resistance of the submersible piston in the liquid, the time required for the submersible piston to move from one end of the piston cylinder to the other end can be accurately calculated. To control the speed of the engine, according to the one-way running time of the submerged piston in the piston cylinder, the angle between the piston cylinder and the vertical line of the engine center axis is set as the starting angle of the submerged piston movement. When the engine rotating disk rotates clockwise, when the piston cylinder on the right side of the vertical line of the engine center axis rotates to any angle below the horizontal plane of the engine center axis, the piston fixed angle control switch drives the piston movement controller to release the submerged piston. Under the action of the buoyancy of the liquid, the submerged piston will float upward from the rotating wheel rim end and move rapidly toward the direction of the hub platform on the outer edge of the center axis. At this time, the torque of the submerged piston will decrease, thereby reducing the speed of the engine rotating disk. At the same time, when the piston cylinder on the left side of the vertical line of the engine center axis rotates to any angle above the horizontal plane of the engine center axis, the piston fixed angle control switch drives the piston movement controller to release the submerged piston. Under the action of the buoyancy of the liquid, the submerged piston will float upward from the hub platform end on the outer edge of the center axis and move rapidly. The submerged piston moves in the direction of the rotating wheel rim at a high speed. At this time, the torque of the submerged piston will increase, forming an opposite torsional force, which reduces the speed of the engine rotating disk. It can be seen that when the starting angle of the submerged piston movement is larger, the submerged piston is released to allow the submerged piston to start the upward movement, and the engine speed will be smaller. When the starting angle of the submerged piston movement is smaller, the submerged piston is released to allow the submerged piston to start the upward movement, and the engine speed will be larger. Therefore, according to the speed ratio of the multi-stage gearbox and the speed requirement of the generator, the starting angle of the submerged piston movement can be calculated and determined. According to the determined starting angle of the submerged piston movement, the movement of the submerged piston can be controlled by the piston fixed angle control switch and the piston movement controller, so as to accurately control the cyclic reciprocating motion cycle of the submerged piston, thereby controlling the engine speed to meet the generator's requirements for the engine output speed. When the engine rotating disk rotates counterclockwise, the engine speed control method is the same as the above method. (5) Calculate and determine the power of the engine. The power of the engine driven by the submerged and floating pistons is the sum of the power generated by the reciprocating motion of all the submerged and floating pistons and the power generated by the circulating flow of the liquid in all the piston cylinders and the gravity box. The specific power calculation method is as follows: For the submerged piston, according to the torque calculation formula M 活 =F×L, where M 活 is the moment of the submerged piston mass center, F is the gravity of the submerged piston mass center, L is the vector distance between the submerged piston mass center and the vertical line of the engine center axis, according to the engine power generation method, the torque difference ΔM generated by the submerged piston in the piston cylinder on the left and right sides of the vertical line of the engine center axis 活 for: Among them, F 活 is the gravity of the center of mass of the submerged piston in each piston cylinder. The gravity of the center of mass of the submerged piston in each piston cylinder is equal. 右i is the vector distance between the mass center of the submerged piston in the ith piston cylinder to the right of the vertical line of the engine center axis and the vertical line of the engine center axis, L 左i is the vector distance between the mass center of the submerged piston in the ith piston cylinder on the left side of the vertical line of the engine center axis and the vertical line of the engine center axis, n is the number of submerged pistons on one side of the vertical line of the engine center axis. After the number, length, shape, volume, capacity of the piston cylinders and the volume and weight of the submerged pistons are determined, the torque difference of the submerged pistons in the piston cylinders on the left and right sides of the vertical line of the engine center axis can be calculated. According to the engine speed control method, the engine speed can be determined. According to the engine power calculation formula P 活 =ΔM 活 ×N / 9549, where P 活 is the power generated by the reciprocating motion of the submerged piston, N is the engine speed, and the engine power calculation formula can be used to calculate the engine power driven by the submerged piston; For the liquid in the piston cylinder and gravity box, according to the torque calculation formula M 液 =F×L, where M 液 is the gravity moment of the center of mass of the liquid in the piston cylinder and the gravity box, F is the gravity of the center of mass of the liquid in the piston cylinder and the gravity box, L is the vector distance between the center of mass of the liquid in the piston cylinder and the gravity box and the vertical line of the engine center axis. When all the outer gravity boxes rotate clockwise, the liquid in the outer gravity box and the piston cylinder on the left side of the vertical line of the engine center axis always flows to the inner gravity box, so that the vector distance between the center of mass of the liquid in the piston cylinder and the gravity box on the left side of the engine center axis and the vertical line of the engine center axis is reduced. At the same time, the liquid in the inner gravity box and the piston cylinder on the right side of the vertical line of the engine center axis always flows to the outer gravity box, so that the vector distance between the center of mass of the liquid in the piston cylinder and the gravity box on the right side of the engine center axis and the vertical line of the engine center axis is increased. This causes a gravity moment difference between the center of mass of the liquid in the piston cylinder and the gravity box on the left and right sides of the vertical line of the engine center axis, that is, Among them, ΔM 液 is the gravity moment difference between the piston cylinder on the left and right sides of the vertical line of the engine center axis and the center of mass of the liquid in the gravity box, F 液 is the gravity of the center of mass of the liquid in each piston cylinder and gravity box. If the volume and weight of the liquid in each piston cylinder and gravity box are the same, then the gravity of the center of mass of the liquid in each piston cylinder and gravity box is also equal. 右i is the vector distance between the i-th piston cylinder on the right side of the vertical line of the engine center axis and the center of mass of the liquid in the gravity box and the vertical line of the engine center axis, L 左i It is the vector distance between the center of mass of the liquid in the i-th piston cylinder and gravity box on the left side of the vertical line of the engine center axis and the vertical line of the engine center axis. n is the number of piston cylinders on one side of the vertical line of the engine center axis. After the number, length, shape, volume, capacity of the piston cylinder and gravity box and the volume and weight of the liquid in the piston cylinder and gravity box are determined, the gravity moment difference between the center of mass of the liquid in the piston cylinder and gravity box on the left and right sides of the vertical line of the engine center axis can be calculated. According to the engine speed control method, the engine speed can be determined. According to the engine power calculation formula P 液 =ΔM 液 ×N / 9549, where P 液 is the power generated by the circulation of liquid in the piston cylinder and gravity box, N is the engine speed, and the power generated by the circulation of liquid in the piston cylinder and gravity box can be calculated by the engine power calculation formula. Therefore, the power P of the engine driven by the submerged piston is P = P 活 +P 液 , when all the external gravity boxes rotate in the counterclockwise direction, only the engine rotating disk rotates in the counterclockwise direction, and the engine power is the same; (6) The output power of the engine is increased by the coaxial series operation method of the submerged piston cooperatively driven engine. When the output power of a submerged piston cooperatively driven engine cannot meet the power requirement of the generator, two or more submerged piston cooperatively driven engines with the same rotation speed and the same rotation direction can be connected in series on a rotating shaft to form a series engine group according to the power requirement of the generator and the output power of a single submerged piston cooperatively driven engine. The two or more submerged piston cooperatively driven engines jointly drive a rotating shaft to rotate, thereby effectively increasing the output power of the series engine group to meet the power requirement of the generator. However, it must be ensured that the two or more submerged piston cooperatively driven engines connected in series on the same rotating shaft should have the same rotation speed and the same rotation direction, so as to ensure that the two or more engines can drive a rotating shaft to rotate synchronously at the same frequency; (7) Start the engine rotating disk. When the submersible piston generator set is started, first open the generator set electronic lock, then press the start button, and the intelligent control system controls the motor in the start and brake controller to start. The motor first pulls the brake pad drive mechanism to separate the two brake pads from the start and brake discs, releasing the clamping effect of the brake pads on the start and brake discs. Then, the motor pushes the start gear through the start gear connection mechanism to engage with the start and brake disc outer edge gear, assisting in driving the start and brake disc to rotate, and driving the engine rotating disk and the engine center shaft to rotate, so that the engine speed quickly reaches the set speed. At this time, the intelligent control system controls the start gear to separate from the start and brake disc outer edge gear, and turns off the motor; (8) Drive the generator rotor winding to rotate and generate electricity. After the engine rotating disk reaches the set speed, all the submerged pistons continuously and stably perform circular reciprocating motion in their respective piston cylinders, so that the submerged pistons on the left and right sides of the vertical line of the engine center axis continuously generate torque difference and torque difference. At the same time, the liquid in all piston cylinders and gravity boxes continuously and regularly circulates in their respective piston cylinders and gravity boxes, so that the liquid in the piston cylinders and gravity boxes on the left and right sides of the vertical line of the engine center axis continuously generate gravity moment difference and torque difference. The torque difference and torque difference generated by the submerged pistons and the gravity moment difference and torque difference generated by the liquid continuously drive the piston cylinder and the gravity box to rotate, and drive the engine rotating disk and the engine center axis to rotate. The driving wheel on the engine center axis drives the power input wheel of the multi-stage gearbox to rotate. After the multi-stage gearbox is changed in speed, it outputs the speed and power required by the generator, drives the generator rotor winding to rotate and generate electricity, and provides users with stable and high-quality electricity.
