Description

Technical Field

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

[0002] Engines are the main source of power for various industries such as industry, agriculture, and services. In the domestic and foreign engine markets, there are steam turbine engines, diesel engines, gasoline engines, gas engines, electric motors, and nuclear engines. The use of steam turbine engines, diesel engines, gasoline engines, and gas engines requires the combustion of a large amount of coal, oil, and natural gas resources. The use of electric motors consumes a lot of electricity, and more than 70% of electricity comes from thermal power plants. The production of this electricity also requires the combustion of a large amount of fossil energy such as coal, oil, and natural gas. As a result, a large amount of greenhouse gases such as carbon dioxide are continuously emitted, and the phenomenon of global warming continues to intensify, resulting in frequent natural disasters and major epidemics, which seriously threatens human survival and safety. Countries around the world are seeking new power sources to replace traditional power. Although many countries have developed clean electricity such as hydropower, wind power, and solar power, hydropower is affected by weather, precipitation during the wet and dry seasons, catchment area and reservoir capacity, and natural environmental conditions; wind power is affected by wind force, weather and seasonal changes, and natural environmental conditions; and solar power is affected by sunshine time, day and night changes, weather and seasonal changes, and natural environmental conditions. As a result, the electricity produced by these power generation systems is unstable, the quality of electricity is not high, and the construction cost of these power generation facilities is very high; although the power generated by nuclear engines is very stable, it consumes expensive nuclear materials, and once a nuclear leak or nuclear explosion occurs, it will cause great losses and damage to life, property, and the ecological environment in the surrounding areas. Therefore, humans urgently need to explore and apply new engine technologies and equipment that are highly stable, efficient, clean, high-quality, resource-free, and low-cost to build.

[0003] Through scientific and technological literature retrieval and investigation and research, although some researchers are exploring experiments to convert gravity and buoyancy into power, the existing technology for converting gravity and buoyancy into power simply uses the interaction force between gravity and buoyancy. The method is too simple and does not solve the problem of coordinated driving of gravity and buoyancy, let alone the stability and efficiency of power generation, resulting in low power stability and low efficiency of power generation. As a result, these technical achievements lack innovation and practicality, and cannot achieve industrial development and large-scale production. So far, there is no technology and equipment on the market that converts gravity and buoyancy into power that has been truly put into commercial application.

[0004] It is under the above social needs and background technology that the inventors have created the theory of cold static energy and the method and technology of cold static energy conversion after long-term in-depth research and development and prototype testing, and created the submerged piston cooperative driving technology, engine starting and braking technology and intelligent control technology that effectively convert gravitational potential energy and buoyancy potential energy into cooperative driving force, which greatly improves the stability, reliability, sustainability and power generation efficiency of the power system. On this basis, a highly stable, efficient, clean, high-quality, resource-free and low-cost submerged piston cooperative driving engine and power generation and control method were invented. The present invention can fully realize industrial development and large-scale production. Summary of the invention

[0005] In fact, any object at any location on the earth has stable and unchanging gravitational potential energy, and gravitational potential energy is everywhere, always available, inexhaustible, and inexhaustible; in a closed container of a certain volume and shape, the liquid always has an upward buoyancy on the object in the liquid, and the buoyancy is stable and unchanging. The direction of gravity is always vertically downward, while the direction of buoyancy is always vertically upward, maintaining the opposite direction of gravity. Gravitational potential energy and buoyancy potential energy are not affected by weather and seasonal changes, day and night changes, and natural environmental conditions. Therefore, by cleverly and effectively utilizing the synergistic driving effect of gravitational potential energy and buoyancy potential energy, we can continuously obtain stable, efficient, and high-quality power.

[0006] The present invention provides a submersible piston cooperative drive engine and a power generation and control method, which effectively solves the technical and equipment problems of the cooperative drive of gravity potential energy and buoyancy potential energy, and constructs a stable, clean and sustainable new power system. The entire power generation and use 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, does not require the use of unstable natural forces such as wind, river water, lake water, waves, tides, geothermal energy, and solar energy, and is not affected by changes in the natural environment. It also ensures the stability, continuity, and high quality of the power, truly realizing energy conservation, environmental protection, green development, and sustainable development.

[0008] A submersible piston cooperative drive engine includes a support mechanism system, a plurality of piston cylinders and gravity boxes at both ends thereof, equal amounts of liquid in each piston cylinder and the gravity box, a plurality of submersible pistons or a submersible piston string, a plurality of piston motion controllers, a plurality of piston fixed angle control switches, a starting and braking system and an intelligent control system, wherein:

[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, and the center axis bracket is installed It is installed and fixed on the engine base; the rotating wheel rim support platform, the center axis outer edge hub platform and the rotating wheel rim fixed bracket constitute the piston cylinder support platform, each submersible piston cooperative driving engine has a number of evenly distributed piston cylinder support platforms, and 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 submersible piston or a submersible piston string, two piston motion controllers and two piston fixed angle control switches, and the volume, shape and weight of each submersible piston or submersible piston string located in the piston cylinder are exactly the same, and the rotating wheel rim, the starting and braking disc, the rotating wheel rim fixed bracket, the circular sheet stirrups, the rotating wheel rim support platform, the center 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 submersible piston or the submersible piston string, the piston motion controller, the piston fixed angle control switch, and the engine center 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 flowing 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 gravity box 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, and a piston sliding groove parallel to each other is installed on the inner wall on both sides of each piston cylinder. The submersible piston or submersible piston string performs 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 on the inner wall at both ends of the piston cylinder to control the locking and starting of the submersible piston or 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 perform the buoyancy movement. The length, shape, volume, capacity of the piston cylinder and the length and volume 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, that is, the liquid level of the liquid in the piston cylinder is just the height that allows the piston motion controller to lock the submerged piston or the submerged piston string 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 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;

[0012] The submersible piston and submersible piston string are composed of a gravity body and a closed hollow floating body. The gravity body is placed in the middle position of the closed hollow floating body 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. 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 bearing pulleys on both sides of the submersible piston are clamped in the middle of the parallel tracks of the two piston sliding grooves, so that the submersible piston can slide cyclically along the parallel tracks of the piston sliding groove without leaving the piston sliding groove; in order to efficiently utilize the buoyancy potential energy and gravity potential energy, which are stable, clean and permanently usable energies, the buoyancy potential energy and gravity potential energy are effectively converted into The buoyancy of the submerged piston is transformed into a synergistic driving force, and the synergistic driving force is transformed into rotational power. When designing and manufacturing the submerged piston, the liquid buoyancy on the submerged piston is always greater than its own gravity, so that the submerged 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 piston continuously performs a circular reciprocating motion along the parallel track of the piston sliding groove under the synergistic effect of the liquid buoyancy and its own gravity, so that the submerged pistons on the left and right sides of the vertical line of the engine center axis produce a torque difference and a 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 a gravity torque difference and a 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 submersible piston string is formed by connecting two or more independent submersible pistons in series and tightly connected. The submersible piston string is uniformly installed on the piston sliding groove, and as a whole, it performs cyclic reciprocating motion along the parallel track of the piston sliding groove under the coordinated action of the liquid buoyancy and its 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 two submersible piston connecting parts become 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 engine drive 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 central axis, and improving the speed and output power of the engine driven by the submersible piston cooperatively;

[0013] Regarding the starting and braking 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 cooperates to drive the engine to start and stop, 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 submerged piston cooperatively driven engine, 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 control cables, and is linked to the starting and braking system. Each starting and braking disc is controlled by two symmetrically installed starting and braking controllers, which are fixed on the engine base.

[0014] The intelligent control system is a control system for starting and braking the submerged piston cooperatively driven engine, monitoring the rotation speed of the engine and the multi-stage gearbox, and monitoring the running state of the driven equipment, including a control box, a main board, a control panel, a display screen, a start button, a brake button, an engine electronic lock, a green indicator light for safe operation, a red indicator light for fault warning, an alarm buzzer, a speed sensor, relevant sensors for monitoring the running state of the driven equipment, a control cable, a power cable and an external power supply; when the submerged piston cooperatively driven engine, the multi-stage gearbox and the driven equipment are running normally, the green indicator light for safe operation is on and the red indicator light for fault warning is off; when a fault occurs in the starting and braking system, the rotation speed of the engine or the multi-stage gearbox is abnormal, or the running state of the driven equipment is abnormal, the green indicator light for safe operation is off, the red indicator light for fault warning is on, and the alarm buzzer emits a buzzing sound; the control box of the intelligent control system is installed and fixed on the engine base; the motor, the intelligent control system and the sensor in the starting and braking controller are provided with power by the external power supply.

[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 axis outer edge hub platform, engine center axis, center axis bracket and engine base are the main support structures of the support mechanism system. The rotating wheel rim fixing bracket is both a support 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 axis 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, and 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; the center axis outer edge hub platform is a regular polygonal box centered on the center line of the engine center axis, which is fastened to the engine center axis. The two sides of the regular polygonal box are made of regular polygonal steel plates, and each side of the two regular polygonal steel plates is made of The steel plate is laid and fixed 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 of the piston cylinder is connected and fixed by the rotating wheel rim fixing bracket; the engine center axis is the rotating shaft that carries the submerged piston to drive the engine power output, and is supported by the center axis brackets on both sides of the engine rotating disk. The engine center axis and the center axis bracket are connected and supported by high-strength bearings; the engine base is a mechanism that carries the submerged piston to drive the engine, the starting and braking controller, the intelligent control system, the multi-stage gearbox, and the driven equipment. The driven equipment refers to generators, transportation equipment, and industrial equipment that require rotating power.

[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 mean that the thickness of the piston cylinder and the gravity box at both ends are the same, and the thickness of the piston cylinder and the gravity box are also the same. 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 and each 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 gravity box can also be designed and manufactured into a piston cylinder and gravity box of an unbalanced structure. The piston cylinder of the unbalanced structure The cylinder and the gravity box mean 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 piston cylinders together with the outer gravity box can be installed at the same inclination angle in the direction of rotation to form 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 and manufactured into a 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 high-strength and 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 designed and manufactured into a cube, a cuboid, a polygon, 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 materials with large specific gravity. The airtight hollow buoyancy body of the submersible piston can be made of iron, aluminum, light alloy, acrylic (polymethyl methacrylate), PVC (polyethylene), PET (polyethylene terephthalate), resin, ceramic or other high-strength 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-like stirrup, a rotating wheel rim supporting platform, a center axis outer edge hub platform, a piston cylinder, an outer gravity box, an inner gravity box, liquids 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 center 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 the piston cylinders perform cyclic reciprocating motion in turn under the coordinated action of the liquid buoyancy and their own gravity, so that the engine center axis is vertically moved. The submerged pistons on the left and right sides of the straight line continuously generate torque difference and torque difference, and make the submerged piston apply greater torque to the piston cylinder and gravity box on the side with greater torque, thereby driving the piston cylinder and gravity box to rotate, and driving the engine rotating disk and the engine center axis to rotate, and output 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, 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 moment difference and torque difference, and the liquid applies greater torque to the piston cylinder and gravity box on the side with 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 center 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. There are two piston motion controllers in each piston cylinder, which are respectively installed and fixed on the inner walls at both ends of the piston cylinder. The piston motion controller at each end 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 the submersible piston no longer moves. 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. There are two piston fixed angle control switches in each piston cylinder, 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 for the submerged piston to start moving, and 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 activity located at the outer end of the piston cylinder is activated. 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 begins to do the floating 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 begins to do the floating 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] Regarding the power generation and control method of the submersible piston cooperatively driven engine, the specific method is as follows:

[0023] (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; since the liquid buoyancy of the submerged piston is always greater than its own gravity, after injecting liquid into each piston cylinder, each submerged piston always has the ability to float upward;

[0024] (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. If the gravity moment is large, the sum of the gravity moment vectors of the center of mass of the liquid in all gravity boxes and piston cylinders increases, which makes the sum of the gravity moment vectors of the center of mass of the liquid in the gravity box and piston cylinder on the right side of the vertical line of the engine center axis much larger than the sum of the gravity moment vectors of the center of mass of the liquid in the gravity box and piston cylinder on the left side, thus causing the piston cylinder and the liquid in the gravity boxes on the left and right sides of the vertical line of the engine center axis to produce gravity moment difference and torque difference. It is this gravity moment difference and torque difference that causes the liquid to exert a greater torque on the side with a larger gravity moment, i.e., the piston cylinder and the outer gravity box on the right side of the vertical line 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;

[0025] (3) Control the power generation of the engine. The number, length, shape, structure, volume, capacity of the piston cylinder and gravity box, the weight of the liquid in the piston cylinder and gravity box, the volume and weight of the submerged piston, and the starting angle of the submerged piston movement determine the output power, speed and power of the submerged piston cooperatively driven engine. The specific method of controlling the power generation of the engine is:

[0026] When designing and manufacturing the submersible piston, the liquid buoyancy on 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, and the movement state of each submersible piston is accurately controlled by the piston motion controller and the piston fixed angle control switch. Under the coordinated action of the liquid buoyancy and its own gravity, all the submersible pistons perform uniform and regular cyclic reciprocating motion in their respective piston cylinders in turn; when the engine rotating disk rotates clockwise, 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 below the engine center axis, the piston fixed angle control switch drives the piston motion controller to release the submersible piston, and the submersible piston quickly When the submerged piston reaches the end of the piston cylinder at the end of the hub platform at the outer edge of the center shaft, the piston movement controller at the end of the piston cylinder at the end of the hub platform at the outer edge of the center shaft automatically locks the submerged piston, thereby reducing the force arm of the submerged piston's center of mass and also reducing the torque of the submerged piston's center of mass. As the engine rotating disk continues to rotate, all submerged pistons on the left side of the vertical line of the engine's center shaft are locked at the end of the hub platform at the outer edge of the center shaft, thereby minimizing the torque vector sum of all submerged pistons on the left side of the vertical line of the engine's center shaft. At the same time, when the submerged piston on the left side above the horizontal plane of the engine's center shaft approaches the left side of the upper vertical line of the engine's center shaft, the piston fixed angle control switch drives the piston to move. The piston motion controller releases the submerged piston, and the submerged piston moves rapidly toward the rotating wheel rim. When the submerged piston reaches the end of the piston cylinder at the rotating wheel rim end, the piston motion controller at the end of the piston cylinder at the rotating wheel rim end automatically locks the submerged piston, increasing the force arm of the submerged piston's center of mass and the torque of the submerged piston's center of mass. As the engine rotating disk continues to rotate, all the submerged pistons on the right side of the vertical line of the engine's central 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's central 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's central axis. It is the existence of this torque difference and torque difference that The submerged piston applies a greater torque to the piston cylinder and the gravity box on the side with a large torque, thereby driving the piston cylinder and the gravity box to rotate continuously and stably, and driving the engine rotating disk and the engine central axis to rotate, and output power to the outside; at the same time, during the continuous rotation of the engine rotating disk, the liquid in each piston cylinder and the gravity box circulates continuously and regularly, 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 central axis produces a gravity moment difference and a torque difference. This gravity moment difference and torque difference causes the liquid to apply a greater torque to the piston cylinder and the gravity box on the side with a large torque, driving the piston cylinder and the gravity box to rotate, and driving the engine rotating disk and the engine central axis 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 and the rotational torque of the liquid in the piston cylinder and the gravity box.When the engine rotating plate rotates counterclockwise, 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 and liquid weight of 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 liquid weight of the piston cylinder and the gravity box and the volume and weight of the submersible piston are determined, the engine speed can be accurately controlled by controlling the starting angle of the submersible piston movement. The specific method of engine speed control 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, by calculating the liquid 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 engine speed: according to the one-way running time of the submerged piston in the piston cylinder, set the angle between the piston cylinder and the vertical line of the engine center axis as the starting angle for the submerged piston to start moving. When the engine rotating disk rotates in the clockwise direction, 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 controls the piston movement controller to release the submerged piston, and the submerged piston will float upward from the rotating wheel rim end and move quickly 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, causing the speed of the engine rotating disk to decrease. At the same time, 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 controls the piston movement controller to release the submerged piston. The submerged piston will float upward from the rotating wheel rim end and move quickly 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, causing the speed of the engine rotating disk to decrease. 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 controls the piston motion controller to release the submerged piston, and the submerged piston will float upward from the inner gravity box and move rapidly toward the rotating wheel rim. At this time, the torque of the submerged piston will increase, forming an opposite torque, which reduces the speed of the engine rotating disk. It can be seen that when the starting angle of the submerged piston movement is smaller, the submerged piston is released to allow the submerged piston to start moving, and the engine speed is higher. When the starting angle of the submerged piston movement is larger, the submerged piston is released to allow the submerged piston to start moving, and the engine speed is lower. Therefore, according to the engine speed requirements, the reciprocating motion cycle of the submerged piston can be accurately controlled by controlling the starting angle of the submerged piston movement through the piston fixed angle control switch and the piston motion controller, thereby controlling the engine speed to meet the requirements of the multi-stage gearbox and the driven equipment 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 cooperatively driven 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, 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 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 piston cylinders on one side of the vertical line of the engine center axis. After the number of piston cylinders, the length of the force arm of the mass center of the submerged piston, and the gravity of the mass center of the submerged piston are determined, the torque difference of the submerged piston 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 power calculation formula P 活 =ΔM 活 ×N / 9549, where P 活 is the power generated by the reciprocating motion of the submerged piston, and N is the engine speed. The engine speed can be determined according to the engine speed control method. Therefore, the engine power driven by the submerged piston can be calculated by the engine power calculation formula;

[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, 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 vertical line 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 vertical line of the engine center axis and the vertical line of the engine center axis is increased. This causes a gravity moment difference between 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 F is the gravity moment difference between the piston cylinder on the left and right sides of the vertical line of the engine central axis and the center of mass of the liquid in the gravity box, 液 is the gravity of each piston cylinder and the center of mass of the liquid in the gravity box. The gravity of each piston cylinder and the center of mass of the liquid in the gravity box is 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 i-th piston cylinder on the left side of the vertical line of the engine center axis and the center mass of the liquid in the gravity box 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 structure, volume, capacity of the piston cylinder and the gravity box and the weight of the liquid in the piston cylinder and the gravity box are determined, 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 mass of the liquid in the gravity box 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 and the gravity box, N is the engine speed. According to the engine speed control method, the engine speed can be determined. Therefore, 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) Start the engine rotating disc. Open the engine electronic lock and press the start button. The intelligent control system controls the motor to start through the motor intelligent switch in the start and brake controller. The motor first pulls the brake pad drive mechanism so that the two brake pads on the brake pad drive mechanism leave the start and brake disc, releasing the clamping effect of the brake pad on the start and brake disc. Then, the motor pushes the start gear to engage with the outer gear of the start and brake disc through the start gear connection mechanism, assisting the start and brake disc to rotate, and driving the engine rotating disc and the engine center axis 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 outer gear of the start and brake disc, and turns off the motor.

[0035] (7) Continuously and stably output power. When the engine speed reaches the set speed, all the submerged pistons continuously 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 the piston cylinder and the gravity box continuously and regularly circulates in their respective piston cylinders and the gravity box, 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 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 jointly 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 multi-stage gearbox power input wheel 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 driven equipment, driving the driven equipment to work;

[0036] (8) The coaxial series operation method increases the output power of the engine. In the actual use of the submersible piston cooperatively driven engine, when the output power of a submersible piston cooperatively driven engine cannot meet the power requirement of the driven equipment, the present invention creates a coaxial series operation method to increase the output power of the engine. The coaxial series operation method is to accurately calculate the output power of the submersible piston cooperatively driven engine and the power requirement of the driven equipment, and then connect two or more submersible piston cooperatively driven engines with the same speed and the same rotation direction in series on a rotating shaft to form a series engine group, and drive a rotating shaft to rotate by two or more submersible piston cooperatively driven engines together, thereby effectively increasing the output power of the series engine group and meeting the power requirement of the driven equipment. In order to ensure that two or more submersible piston cooperatively driven engines operate in coordination, it is necessary to ensure that the two or more engines connected in series on the same rotating shaft should have the same 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.

[0037] Regarding the method of connecting the submersible piston cooperatively driven engine to drive the multi-stage gearbox and the driven equipment, first of all, there are two ways to install the submersible piston cooperatively driven engine on the engine base, 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 engine base 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 engine base 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 driven equipment:

[0038] (1) Belt connection drive method. After accurately calculating the speed ratio between the driving 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 rotating shaft of the driven equipment, a driving 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 rotating shaft of the driven equipment. When the submerged piston cooperative drive engine is running, the driving 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 rotating shaft of the driven equipment through a belt, and drives the pulley on the rotating shaft of the driven equipment to rotate, thereby driving the driven equipment to work;

[0039] (2) Gear connection drive method. After accurately calculating the speed ratio between 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 rotating shaft of the driven equipment. When the submerged piston cooperative drive engine is running, the drive gear on the central shaft of the engine 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 and drives the gear on the rotating shaft of the driven equipment to rotate, thereby driving the driven equipment to work;

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 rotating shaft of the driven equipment. When the submerged piston cooperative drive engine is running, the drive pulley on the central shaft of the engine is connected by 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 meshes and drives the gear on the rotating shaft of the driven equipment to rotate, thereby driving the driven equipment to work;

After accurately calculating the speed ratio between 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 rotating shaft of the driven equipment. When the submerged piston cooperative drive engine is running, the drive gear on the central shaft of the engine 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 through a belt and drives the pulley on the rotating shaft of the driven equipment to rotate, thereby driving the driven equipment to work;

[0042] (5) Belt direct connection drive method. After accurately calculating the speed ratio between the drive pulley on the central shaft of the submerged piston cooperative drive engine and the pulley on the rotating shaft of the driven equipment, if the output speed of the submerged piston cooperative drive engine is consistent with the speed required by the driven equipment, there is no need for a multi-stage gearbox for speed change processing. A drive 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 rotating shaft of the driven equipment. When the submerged piston cooperative drive engine is running, the drive pulley on the central shaft of the engine is connected through a belt and drives the pulley on the rotating shaft of the driven equipment to rotate, thereby driving the driven equipment to work;

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

[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 cooperative drive engine, thereby greatly improving the practicality of the submersible piston cooperative drive engine.

[0045] Since the present invention adopts the above technical solution, it has the following advantages and significant effects compared with the prior art:

[0046] (1) The present invention creates a submersible piston cooperative driving method and technology that effectively converts gravitational potential energy and buoyancy potential energy into cooperative driving force, and creates a submersible piston cooperative driving engine that can continuously provide highly stable and high-quality power supply, thereby making the stable, clean and permanently usable cooperative driving force converted from gravitational potential energy and buoyancy potential energy a new and important power source.

[0047] (2) The present invention creates a complete set of piston cylinders and gravity boxes, submerged pistons, piston motion controllers, piston fixed angle control switches, starting and braking systems, intelligent control systems and groundbreaking support mechanism systems and components, as well as engine rotation direction control methods, speed control methods and power control methods based on the balanced structure and unbalanced structure of the power system. Through the use of the above equipment, systems, support mechanism systems, components and methods, on the one hand, the efficiency of converting gravitational potential energy and buoyancy potential energy into cooperative driving force is greatly improved, and the stability, reliability and sustainability of engine power generation are comprehensively improved; on the other hand, through the creation and application of engine rotation direction control methods, speed control methods and power control methods, a complete set of groundbreaking engine output direction, output speed and output power control technologies are constructed, which greatly improves the function and performance of the submerged piston cooperative drive engine, and can construct submerged piston cooperative drive engines of various speeds and various powers, which well meets the needs of various users for engines of different powers and different models, thereby effectively ensuring the originality and practicality of the submerged piston cooperative drive engine.

[0050] (5) The submersible piston cooperatively driven engine only requires stable gravitational potential energy and buoyancy energy, and has high efficiency, good stability and sustainability in power generation. In addition, the submersible piston cooperatively driven engine has a low cost. At the same time, according to the purpose and power requirements of the submersible piston cooperatively driven engine, a series of submersible piston cooperatively driven engine products of various powers and models can be designed and manufactured. Therefore, the present invention can be fully put into commercial application and industrial development, and has broad market prospects.

[0051] (6) Compared with existing steam turbine engines, diesel engines, gasoline engines, and gas engines, these engines need to burn a large amount of coal, oil, and natural gas resources, generating a large amount of greenhouse gas emissions and environmental pollution. The submerged piston cooperatively driven engine does not need to consume any fossil energy, but only requires stable gravitational potential energy and buoyancy potential energy, and does not produce any harmful substance emissions or environmental pollution. Therefore, the industrialization of the results of the present invention plays an extremely important role in gradually reducing and replacing engines that use fossil energy as the main body, reducing greenhouse gas emissions and environmental pollution, and accelerating the realization of carbon peak and carbon neutrality goals.

[0052] (7) Compared with electric motors, electric motors need to consume a lot of electricity to generate power, and the electricity comes from thermal power plants, hydropower stations, wind farms and solar power stations. Thermal power plants also need to burn a lot of coal, oil and natural gas resources, resulting in a lot of greenhouse gas emissions and environmental pollution. Hydropower, wind power, solar power, wave and tidal power, geothermal power and other power generation methods are directly affected by weather, climate, season, day and night, geographical location and natural environmental conditions, resulting in unstable power and low power quality. The submersible piston cooperative drive engine neither consumes any fossil energy nor is affected by weather, climate, season, day and night, geographical location and natural environmental conditions. The power generated has good stability, continuity and high quality, and the power generation and use process will not have any impact on the surrounding ecological environment. In contrast, the submersible piston cooperative drive engine has unique advantages.

[0053] (8) Compared with nuclear power engines, nuclear power engines consume expensive nuclear materials and produce radioactive nuclear waste. In particular, once a nuclear leak or nuclear explosion occurs, it will cause great loss and damage to life, property and the ecological environment in the surrounding areas. During operation, the submersible piston cooperative drive engine does not consume any nuclear materials, nor does it have any nuclear radiation or safety hazards. It is a very safe and reliable power system.

[0054] (9) 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 foreign manufacturers. Therefore, there are no trade barriers to the industrial development of the present invention. Looking at the existing engine technology and equipment, the present invention, as a set of subversive original scientific and technological achievements, will completely change the power structure of mankind after its large-scale industrial development, and strongly promote the world power revolution and industrial transformation.

[0065] See also Figure 3 and Figure 4The piston cylinder 1 and the gravity box are cylindrical closed boxes, with a gravity box at each end of the piston cylinder 1. The gravity box and the piston cylinder 1 form an angle of 90 degrees or other angles, which is also called a "double elbow gravity box".

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; when designing and making the submersible piston 4, always The liquid buoyancy exerted on the submerged piston 4 is made greater than its own gravity, so that the submerged 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 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 piston 4 on the left and right sides of the vertical line of the engine center axis 7 produces 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 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 produces a gravity torque difference and a torque difference, and it is the torque difference and torque difference generated by the submerged piston 4 and the gravity torque difference and 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 center axis 7 to rotate, and output power to the outside. The submersible piston string is formed by connecting two or more independent submersible pistons 4 in series and tightly connected. The submersible piston string is uniformly installed on the piston sliding groove, and as a whole, it performs cyclic reciprocating motion along the parallel track of the piston sliding groove under the coordinated action of the liquid buoyancy and its own gravity; the entire submersible piston string is designed and manufactured into a "shuttle shape", and the connecting parts of the two submersible pistons 4 are the same shape as the middle part of the submersible piston 4 and are tightly connected, so that the connecting parts of the two submersible pistons 4 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 4, the submersible piston string can increase the weight of the engine drive 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 central axis 7, and improving the speed and output power of the submersible piston cooperatively driven engine;

[0068] See also Figure 1 and Figure 2, the starting and braking system is described in detail. After the same amount of liquid is injected into each piston cylinder 1 and the gravity box, the weight and inertia of the engine rotating disk are greatly increased.

When the submerged piston cooperatively drives the engine, the multi-stage gearbox 19, and the driven device 20 operate normally, the green indicator light for safe operation is on, and the red indicator light for fault warning is off. When the starting and braking system fails, the speed of the engine or the multi-stage gearbox is abnormal, or the operating status of the driven device 20 is abnormal, the green indicator light for safe operation is off, the red indicator light for fault warning is on, and the alarm buzzer emits a buzzing sound. The control box of the intelligent control system 21 is installed and fixed on the engine base 16. The motor, the intelligent control system 21, and the sensor in the starting and braking controller are powered by an external power supply.

[0071] See also Figure 3 and Figure 4 The piston cylinder 1 and the gravity box can be a balanced structure or an unbalanced structure. Figure 3 It is a plane diagram of a piston cylinder 1 and a gravity box of a balanced structure. Figure 4It is a plan view of the construction of a piston cylinder 1 and a gravity box of an unbalanced structure. The piston cylinder 1 and gravity box of a balanced structure means that the thickness of the piston cylinder 1 and the gravity box at both ends are the same, and the thickness of the piston cylinder 1 and the gravity box are also the same. The piston cylinder 1 is perpendicular to the plane of the hub platform 9 on the outer edge of the central axis, and 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. The piston cylinder 1 and the 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 1 and each gravity box are exactly the same, and the weight of the liquid in each piston cylinder 1 and the gravity box is exactly the same, the piston cylinder 1 and the gravity box can also be designed and manufactured into a piston cylinder 1 and a gravity box of an unbalanced structure. The piston cylinder 1 and the gravity box of an unbalanced structure refers to the piston cylinder 1 The thickness of each end of the gravity box can be different, and the piston cylinder 1 can be designed to be large at one end and small at the other end, and the gravity box can be large at one end and small at the other end. Moreover, the thickness and shape of the piston cylinder 1 and the gravity box can be different, and the volume and capacity of the outer gravity box 2 and the inner gravity box 3 at both ends of the piston cylinder 1 can also be different. Moreover, the piston cylinder 1 and the plane of the hub platform 9 on the outer edge of the central axis may not be perpendicular. All the piston cylinders 1 together with the outer gravity box 2 can be installed at the same inclination angle in the direction of rotation to form an unbalanced structural state. The unbalanced structure piston cylinder 1 and gravity box have good operating stability, and can increase the gravity moment difference and torque difference between the piston cylinder 1 and the liquid in the gravity box, thereby increasing the engine speed and output power.

[0072] See also Figure 3 and Figure 4 The cross-sectional shapes of the piston cylinder 1 and the gravity box can be designed to be square, rectangular, polygonal, circular, elliptical or other suitable shapes.

[0074] See also Figure 1 and Figure 2The engine rotating disk is a rotating mechanism system and power generation system of the engine driven by the submerged piston. 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, liquids 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 each piston cylinder 1 perform cyclic reciprocating motion in turn under the coordinated action of the liquid buoyancy and its own gravity. , which 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, driving the engine rotating disk and the engine center axis 7 to rotate, and outputting power to the outside; at the same time, the liquids located in all the piston cylinders 1 and the gravity box circulate in their respective piston cylinders 1 and gravity boxes in turn, causing the liquids 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.

[0075] See also Figure 2 and Figure 3 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, and the submersible piston 4 no longer moves. 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 coordinated action of the liquid buoyancy and its own gravity.

[0076] See also Figure 2 and Figure 3, 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. 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 a 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, ensuring that the submerged floating piston 4 has a stable and accurate cyclic reciprocating motion cycle, and ensuring that the submerged floating piston cooperates to drive the engine with a stable and accurate speed; when the engine rotating disk rotates counterclockwise, the piston fixed angle control switch 6 is controlled in the same way, and the piston fixed angle control switch 6 is integratedly connected and installed with the piston motion controller 5.

[0077] See also Figure 1 and Figure 2 , the power generation and control method of the submersible piston cooperative drive engine is described in detail, and the specific method is as follows:

[0078] (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; since the liquid buoyancy of the submerged piston 4 is always greater than its own gravity, after injecting an equal amount of liquid into each piston cylinder 1, each submerged piston 4 always has the ability to float upward;

[0079] (2) The rotation direction of the engine rotating disk is controlled by the direction indicated by the outer gravity box 2. When all the outer 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 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 force arm of the center of mass of the liquid in all gravity boxes and the piston cylinder 1 on the left side of the vertical line of the engine center axis 7 is reduced. Since the weight of the liquid in each gravity box and the piston cylinder 1 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 1 on the left side of the vertical line of the engine center axis 7 is 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 2, so that the center of mass of the liquid in all gravity boxes and the piston cylinder 1 on the right side of the vertical line of the engine center axis 7 is reduced. As the lever arm increases, the sum of the gravity moment vectors of the center of mass of the liquid in all gravity boxes and piston cylinder 1 increases, which makes the sum of the gravity moment vectors of the center of mass of the liquid in the gravity box and piston cylinder 1 on the right side of the vertical line of the engine center axis 7 much larger than the sum of the gravity moment vectors of the center of mass of the liquid in the gravity box and piston cylinder 1 on the left side, thus causing gravity moment difference and torque difference in the liquid in the gravity boxes and piston cylinder 1 on the left and right sides of the vertical line of the engine center axis 7. It is this gravity moment difference and torque difference that causes the liquid to exert a greater torque on the side with a larger gravity moment, i.e., the piston cylinder 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;

[0080] (3) Controlling the power generation of the engine. The number, length, shape, structure, volume, capacity of the piston cylinder 1 and the gravity box, the weight of the liquid in the piston cylinder 1 and the gravity box, the volume and weight of the submerged piston 4, and the starting angle of the submerged piston 4 determine the output power, speed and power of the engine driven by the submerged piston. The specific method of controlling the power generation of the engine is:

[0081] 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 the ability to float in the liquid of the piston tube 1. The movement state of 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 tubes 1. When the engine rotating disk rotates clockwise, when the submersible piston 4 located below the horizontal plane of the engine center axis 7 approaches the right side of the lower vertical line of the engine center 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 center axis. When the submersible piston 4 reaches the end of the hub platform 9 on the outer edge of the center axis, the piston motion controller 5 located at the inner end of the piston tube 1 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 submersible piston 4 located below the horizontal plane of the engine center axis 7 is located on the right side of the vertical line of the lower part of the engine center axis 7. All the submerged pistons 4 on the left side of the vertical line of the engine center axis 7 are locked at the end of the hub platform 9 on the outer edge of the center axis, so that the moment vector sum of all the submerged pistons 4 on the left side of the vertical line of the engine center axis 7 is minimized; at the same time, when the submerged piston 4 located above the horizontal plane of the engine center axis 7 approaches the left side of the upper vertical line of the engine center axis 7, the piston fixed angle control switch 6 drives the piston motion controller 5 to release the submerged piston 4, and the submerged piston 4 quickly moves toward the rotating wheel rim 13. When the submerged piston 4 reaches the end of the rotating wheel rim 13, the piston motion controller 5 located at the outer end of the piston cylinder 1 automatically locks the submerged piston 4, so that The increase in the force arm of the submerged piston 4 also increases the torque of the submerged piston 4. As the engine rotating disk continues to rotate, 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 rim 13, so that the moment vector sum of all the submerged pistons 4 on the right side of the vertical line of the engine center axis 7 is the largest. This creates the largest 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 It rotates regularly and drives the engine rotating disk and the engine center axis 7 to rotate, and outputs 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 and the liquid in the gravity box on the left and right sides of the vertical line of the engine center axis 7 produce a gravity moment difference and a torque difference. This gravity moment difference and torque difference causes the liquid to apply a greater torque to the piston cylinder 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;.

[0082] (4) Controlling the engine speed. The speed of the engine driven by the submersible piston is determined by the number, length, volume, capacity of the piston cylinder 1 and the gravity box, the weight of the liquid in the piston cylinder 1 and the gravity box, the volume and weight of the submersible piston 4, and the starting angle when the submersible piston 4 moves. After being determined by the number, length, volume, capacity of the piston cylinder 1 and the gravity box, the weight of the liquid in the piston cylinder 1 and the gravity box, and the volume and weight of the submersible piston 4, the engine speed can be accurately controlled by controlling the starting angle of the movement of the submersible piston 4. The specific method of engine speed control is as follows:

[0083] Calculate the one-way running time of the submerged piston 4 in the piston cylinder 1: Since the liquid buoyancy force on the submerged piston 4 is always greater than its own weight, after the volume and weight of the submerged piston 4, the effective length of the submerged piston 4 in the piston cylinder 1 for cyclic reciprocating motion, and the liquid level heights of the piston cylinder 1 and the liquid in the gravity box are determined, the liquid buoyancy force and its own weight on the submerged piston 4 can be accurately calculated first, and then, by calculating the liquid resistance on which the submerged piston 4 moves in the liquid, the time required for the submerged piston 4 to move from one end of the piston cylinder 1 to the other end can be accurately calculated;

[0084] 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 central axis 7 as the starting angle of the submerged piston 4 movement. When the submersible piston cooperates to drive the engine to rotate in the clockwise direction, 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 controls the piston motion controller 5 to release the submersible piston 4, and the submersible piston 4 will float upward from the outer gravity box 2 and move rapidly toward the hub platform 9 on the outer edge of the center axis. At this time, the torque of the submersible piston 4 will decrease, causing the speed of the engine rotating disk to decrease; at the same time, when the piston cylinder 1 located on the left side of the vertical line of the engine center axis 7 rotates to any angle above the horizontal plane of the engine center axis 7, the piston fixed angle control switch 6 controls the piston motion controller 5 to release the submersible piston 4, and the submersible piston 4 will float upward from the inner gravity box 3 and move rapidly toward the rotating wheel rim 13. At this time, the torque of the submersible piston 4 will increase, forming an opposite torsional force, causing the speed of the engine rotating disk to decrease. It can be seen that when the starting angle of the movement of the submerged piston 4 is smaller, the submerged piston 4 is released to allow the submerged piston 4 to start moving, and the engine speed is greater. When the starting angle of the movement of the submerged piston 4 is larger, the submerged piston 4 is released to allow the submerged piston 4 to start moving, and the engine speed is smaller. Therefore, according to the engine speed requirement, the reciprocating motion cycle of the submerged piston 4 can be accurately controlled by controlling the movement starting angle of the submerged piston 4 through the piston fixed angle control switch 6 and the piston motion controller 5, thereby controlling the engine speed to meet the requirements of the multi-stage gearbox 19 and the driven equipment 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;

[0085] (5) Calculate and determine the power of the engine. The power of the engine driven by the submerged pistons 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 1 and the gravity box. The specific power calculation method is as follows:

[0086] 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, and 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iis 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 piston cylinders 1 on one side of the vertical line of the engine center axis 7, after the number of piston cylinders 1, the length of the force arm of the mass center of the submerged piston 4 and the gravity of the mass center of the submerged piston 4 are determined, the torque difference of the submerged piston 4 in the piston cylinders 1 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 活 =ΔM 活 ×N / 9549, where P 活 is the power generated by the reciprocating motion of the submersible piston 4, and N is the engine speed. The engine speed can be determined according to the engine speed control method. Therefore, the engine power driven by the submersible piston can be calculated by the engine power calculation formula;

[0087] 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 outer gravity box 2 and the liquid in the piston cylinder 1 on the left side of the vertical line of the engine center axis 7 always flow 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 vertical line of the engine center axis 7 and the vertical line of the engine center axis 7 is 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 2, 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 vertical line of the engine center axis 7 and the vertical line of the engine center axis 7 is increased, which makes the piston cylinder 1 and the liquid in the gravity box on the left and right sides of the vertical line of the engine center axis 7 produce a gravity moment difference, that is, Among them, ΔM 液 is the gravity moment difference between the piston cylinder 1 and the liquid in the gravity box on the left and right sides of the vertical line of the engine central axis 7, F 液 is the gravity of each piston cylinder 1 and the center of mass of the liquid in the gravity box. The gravity of each piston cylinder 1 and the center of mass of the liquid in the gravity box is equal. 右i is the vector distance between the i-th piston cylinder 1 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 7, L 左iis 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, capacity 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 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.

[0088] (6) Start the engine rotating disc. Open the engine electronic lock 24, press the start button 22, and the intelligent control system 21 controls the motor to start through the motor intelligent switch in the start and brake controller 17. The motor first pulls the brake pad drive mechanism so that the two brake pads on the brake pad drive mechanism leave the start and brake disc 14, releasing the clamping effect of the brake pad on the start and brake disc 14. Then, the motor pushes the start gear to engage with the outer gear of the start and brake disc 14 through the start gear connection mechanism, assisting the start and brake disc 14 to rotate, and driving the engine rotating disc and the engine center shaft 7 to rotate. In a very short time, the engine speed reaches the set speed. At this time, the intelligent control system 21 controls the start gear to separate from the start and brake disc 14, and turns off the motor;

[0089] (7) Output power continuously and stably. When the engine speed reaches the set speed, all the submerged pistons 4 continuously perform cyclic reciprocating motion in their respective piston cylinders, 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 the piston cylinder 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 cylinder 1 and the gravity box on the left and right sides of the vertical line of the engine center axis 7 continuously generates gravity torque difference and torque difference. The torque difference and torque difference generated by the submerged piston 4 and the gravity torque difference and torque difference generated by the liquid jointly 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 driven device 20, driving the driven device 20 to work.

[0090] (8) The coaxial series operation method increases the output power of the engine. In the actual use of the submersible piston cooperatively driven engine, when the output power of a submersible piston cooperatively driven engine cannot meet the power requirement of the driven device, the present invention creates a coaxial series operation method to increase the output power of the engine. The coaxial series operation method is to accurately calculate the output power of the submersible piston cooperatively driven engine and the power requirement of the driven device 20, and then connect two or more submersible piston cooperatively driven engines with the same speed and the same rotation direction in series on a rotating shaft to form a series engine group, and drive a rotating shaft to rotate by two or more submersible piston cooperatively driven engines together, thereby effectively increasing the output power of the series engine group and meeting the power requirement of the driven device 20. In order to ensure that two or more submersible piston cooperatively driven engines operate in coordination, it is necessary to ensure that the two or more engines connected in series on the same rotating shaft should have the same 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.

[0098] 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 cooperative drive engine, thereby greatly improving the practicality of the submersible piston cooperative drive engine.

[0099] See also Figure 1, further illustrating the working process and technical effect of the submersible piston cooperative drive engine. After each piston cylinder 1 and the gravity box are injected with an equal amount of liquid, when the submersible piston cooperative drive engine needs to be started, first turn on the engine electronic lock 24 on the control panel of the intelligent control system 21, and then press the start button 22. The intelligent control system 21 controls the motor start through the motor intelligent switch in the start and brake controller 17. The motor first pulls the brake pad drive mechanism so that the two brake pads on the brake pad drive mechanism leave the start and brake disc 14, releasing the clamping effect of the brake pad on the start and brake disc 14. Then, the motor pushes the start gear through the start gear connection mechanism to engage with the outer gear of the start and brake disc 14, and assists in driving the start and brake disc 14 together with the engine rotating disc and the engine. The central axis 7 of the engine rotates, 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 has reached 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 the motor is controlled to be turned off through the motor intelligent switch; after the engine rotating disc reaches the set speed, each submerged piston 4, under the coordinated action of the liquid buoyancy in the piston cylinder 1 and its own gravity, performs a cyclic reciprocating motion in its respective piston cylinder 1 in turn, so that the submerged pistons 4 on the left and right sides of the vertical line of the central axis 7 of the engine continuously generate torque difference and torque difference; at the same time, the submerged pistons 4 located between the piston cylinder 1 and the outer gear of the starting and brake disc 14 are The liquid in the gravity box circulates continuously and regularly in the respective piston cylinders 1 and the gravity box, so that the piston cylinders 1 on the left and right sides of the vertical line of the engine central axis 7 and the liquid in the gravity box generate gravity moment difference and torque difference. It is the torque difference and torque difference generated by the submerged piston 1 and the gravity moment difference and torque difference generated by the liquid that jointly drive the piston cylinder 1 and the gravity box to rotate, and drive the engine rotating plate and the engine central axis 7 to rotate. The driving wheel 18 of the engine central 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 driven device 20, driving the driven device 20 to work. When the driving engine needs to stop, press the brake button 23 on the control panel of the intelligent control system 21. The intelligent control system 21 controls the motor to start through the motor intelligent switch in the starting and braking controller 17. The motor drives the brake pad driving mechanism and adopts a disc braking method to push the two brake pads on the brake pad driving mechanism to slowly clamp and brake the starting and braking disc 14 until the engine rotating disc stops smoothly. When the speed sensor of the intelligent control system 21 detects that the engine has stopped, the intelligent control system 21 controls the two brake pads on the brake pad driving mechanism to continue to clamp the starting and braking disc 14, and controls the motor to be turned off through the motor intelligent switch, and then locks the engine electronic lock 24.During the operation of the submersible and floating piston cooperatively driven engine, it 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 will not cause any impact on the surrounding ecological environment.

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 piston motion controller at each end 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 the submersible piston no longer moves. 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.

8. The submersible piston cooperative drive engine according to claim 1, characterized in that: 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. There are two piston fixed angle control switches in each piston cylinder, 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 for the submerged piston to start moving. 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 activity located at the outer end of the piston cylinder is activated. When the piston cylinder 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. The submerged floating piston located at the inner end of the piston cylinder begins to do the upward movement and quickly reaches the outer end of the piston cylinder. The piston motion controller located at the outer end of the piston cylinder immediately locks the submerged floating piston. 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 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 for connection and installation.

9. A method for generating and controlling power of a submersible piston cooperatively driven engine according to any one of claims 1 to 8, characterized in that: The specific method of generating and controlling the power of the submerged and floating piston-driven engine 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, after injecting an equal amount of liquid into each piston cylinder, each submerged piston always has the ability to float upward; (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. Large, then the vector sum of the gravity moments of all gravity boxes and the center of mass of the liquid in the piston cylinder increases, which makes the gravity moment of the gravity box 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 greater than the gravity moment of the gravity box and the center of mass of the liquid in the piston cylinder on the left side. As a result, 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 vertical line 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. The submersible piston always has the ability to float upward in the liquid in the piston cylinder. The movement state of each submersible piston is accurately controlled by the piston motion controller and the piston fixed angle control switch. Under the coordinated action of the liquid buoyancy and its own gravity, all the submersible pistons perform uniform and regular cyclic reciprocating motion in their respective piston cylinders. When the engine rotating disk rotates in a clockwise direction, 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 Under the action of liquid buoyancy, it moves rapidly toward the direction of the hub platform on the outer edge of the center axis. When the submerged piston reaches the hub platform end on the outer edge of the center axis, the piston motion controller automatically locks the submerged piston, thereby reducing the force arm of the submerged piston and also reducing the torque of the submerged piston. As the engine rotating disk continues to rotate, all the submerged pistons on the left side of the vertical line of the engine center axis are locked at the hub platform end on the outer edge of the center axis, thereby minimizing the moment vector sum of all the submerged pistons on the left side of the vertical line of the engine center axis. 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. The submerged piston rapidly moves toward the center axis under the action of liquid buoyancy. It moves in the direction of the rotating wheel rim. When the submerged piston reaches the end of the rotating wheel rim, the piston motion controller automatically locks the submerged piston, which increases the force arm of the submerged piston and 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 end of the rotating wheel rim, so that the moment vector sum of all the submerged pistons on the right side of the vertical line of the engine center axis is maximized. 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 a larger torque, thereby driving the piston cylinder and the gravity box to rotate continuously and stably, and driving the engine to rotate. The large disk and the central axis of the engine rotate to output power to the outside. At the same time, during the continuous rotation of the engine rotating large disk, the liquid in each piston cylinder and gravity box circulates continuously and regularly, causing the piston cylinders on the left and right sides of the vertical line of the engine central axis and the liquid in the gravity box to produce a gravity moment difference and a 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 a larger torque, driving the piston cylinder and the gravity box to rotate, and driving the engine rotating large disk and the engine central axis to rotate, outputting power to the outside. Therefore, 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 the gravity box. When the engine rotating large 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 of the submersible piston movement. The specific method of controlling the engine speed 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 gravity box are determined, the liquid buoyancy and self-weight of the submersible piston can be accurately calculated first. Then, by calculating the liquid 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. Control the engine speed. According to the one-way running time of the submerged piston in the piston cylinder, set the angle between the piston cylinder and the vertical line of the engine center axis as the starting angle for the submerged piston to start moving. When the engine rotating disk rotates in the clockwise direction, 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 controls the piston movement controller to release the submerged piston, and 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, 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 controls the piston movement controller to release the submerged piston, and 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, reducing the speed of the engine rotating disk. The platform end of the wheel hub floats upward and moves rapidly in the direction of the rotating wheel rim. 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 smaller, the submerged piston is released to allow the submerged piston to start moving, and the engine speed will be greater. When the starting angle of the submerged piston movement is larger, the submerged piston is released to allow the submerged piston to start moving, and the engine speed will be smaller. Therefore, according to the engine speed requirement, the starting angle of the submerged piston movement is controlled by the piston fixed angle control switch and the piston motion controller, so as to accurately control the cyclic reciprocating motion cycle of the submerged piston, thereby controlling the engine speed to meet the requirements of the multi-stage gearbox and the driven equipment 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 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 piston cylinders on one side of the vertical line of the engine center axis. After the number of piston cylinders, the length of the force arm of the mass center of the submerged piston, and the gravity of the mass center of the submerged piston are determined, the torque difference of the submerged piston 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 power calculation formula P 活 =ΔM 活 ×N / 9549, where P 活 is the power generated by the reciprocating motion of the submerged piston, and N is the engine speed. The engine speed can be determined according to the engine speed control method. Therefore, the engine power driven by the submerged piston can be calculated by the engine power calculation formula; 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 in the clockwise direction, 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 vertical line 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 vertical line of the engine center axis and the vertical line of the engine center axis is increased. This causes a gravity moment difference between 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 F is the gravity moment difference between the piston cylinder on the left and right sides of the vertical line of the engine central axis and the center of mass of the liquid in the gravity box, 液 is the gravity of each piston cylinder and the center of mass of the liquid in the gravity box. The gravity of each piston cylinder and the center of mass of the liquid in the gravity box is 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 i-th piston cylinder on the left side of the vertical line of the engine center axis and the center mass of the liquid in the gravity box 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 structure, volume of the piston cylinder and the gravity box and the weight of the liquid in the piston cylinder and the gravity box are determined, the gravity moment difference between the piston cylinder 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 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 and the gravity box, N is the engine speed. According to the engine speed control method, the engine speed can be determined. Therefore, 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 in the counterclockwise direction, only the engine rotating disk rotates in the counterclockwise direction, and the engine power is the same; (6) Start the engine rotating disk, turn on the engine electronic lock, press the start button, and the intelligent control system controls the motor to start through the motor intelligent switch in 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 leave the starting and braking disk, releasing the clamping effect of the brake pad on the starting and braking disk. Then, the motor pushes the starting gear to engage with the outer gear of the starting and braking disk through the starting gear connection mechanism, assisting the driving of the starting and braking disk to rotate, and driving the engine rotating disk and the engine center axis to rotate, so that the engine speed quickly reaches the set speed. At this time, the intelligent control system controls the starting gear to separate from the outer gear of the starting and braking disk, and turns off the motor; (7) Output power continuously and stably. When the engine speed reaches the set speed, all the submerged pistons continuously perform 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 the piston cylinder and the gravity box continuously and regularly circulates in their respective piston cylinders and the gravity box, 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 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 jointly 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 changes speed, the power output wheel of the multi-stage gearbox outputs the speed and power required by the driven equipment, driving the driven equipment to work; (8) The coaxial series operation method increases the output power of the engine. When the output power of a submerged piston cooperatively driven engine cannot meet the power requirement of the driven equipment, two or more submerged piston cooperatively driven engines with the same speed and rotation direction can be connected in series on a rotating shaft to form a series engine group. 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 and meeting the power requirement of the driven equipment. 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 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.

10. A method for connecting a multi-stage gearbox and a driven device by using a submersible piston cooperatively driven engine as described in any one of claims 1 to 8, characterized in that: There are two ways to install the submersible piston cooperatively driven engine on the engine base, namely vertical installation and parallel installation.
