Description

Technical Field

[0001] The invention belongs to the field of engine systems, and in particular relates to a piston motion controller. Background Art

[0002] At present, in the domestic and foreign engine markets, the main engines are steam turbine engines, diesel engines, gasoline engines, gas engines, electric motors and nuclear engines. However, the use of steam turbine engines, diesel engines, gasoline engines and gas engines requires the combustion of a large amount of fossil energy such as coal, oil and natural gas. 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 coal, oil and natural gas resources. 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 serious Disease epidemics seriously threaten human safety and survival; although nuclear engines are a clean power system, they consume expensive nuclear materials, and once a nuclear leak or nuclear explosion occurs, it will cause great losses and damage to life, property and ecological environment in the surrounding areas; hydroelectric power generation, wind power generation, solar power generation, etc. can produce a large amount of electricity to provide energy for motors, but hydroelectric power generation, wind power generation, solar power generation are directly affected by factors such as weather, climate, season, day and night alternation and natural environmental conditions, resulting in unstable electricity produced by these power generation systems, low power quality, and high construction costs of these power generation facilities. Therefore, humans are in urgent need of exploring and applying new engine technologies and equipment with high stability, high efficiency, high cleanliness, high quality, low resource consumption and low construction cost. Against the above background, the inventors have invented a submerged piston cooperative drive engine and a power generation and control method. The submersible piston cooperative drive engine is an engine that fully utilizes the stable, clean, and permanently usable energy of gravitational potential energy and buoyancy potential energy, and effectively converts the gravitational potential energy and buoyancy potential energy into a cooperative driving force, creating an engine that outputs high-quality power stably, continuously, and efficiently. Among them, the inventor invented the key core technology and equipment of the submersible piston, and the precise control of the submersible piston operation cycle is the key to the submersible piston cooperative drive engine to generate high-quality power. To this end, the inventor invented a piston motion controller to achieve locking and releasing control of the submersible piston, ensuring the accurate stopping and accurate starting of the submersible piston movement.

[0003] Through scientific and technological literature retrieval and investigation and research, although some researchers have explored and experimented with methods and devices for generating power using gravity and buoyancy, these methods and devices are too simple and fail to solve the technical problem of effectively converting gravitational potential energy and buoyancy potential energy into a synergistic driving force, and have not solved the efficiency problem of power generation and the stability, reliability and sustainability of power, making these research results lack innovation and practicality. So far, no gravity and buoyancy engine has been truly put into commercial application. At present, no researchers at home or abroad have been found to conduct research similar to the submerged piston synergistic drive engine, nor have any researchers been found to study the submerged piston. Therefore, no research and application similar to the piston motion controller has been found. Summary of the invention

[0004] In order to solve the above problems, the technical problem to be solved by the present invention is to provide a piston motion controller, which realizes the locking and releasing control of the submersible piston, ensures the accurate stopping and starting of the submersible piston movement, and makes the submersible piston cyclic motion have good stability, reliability and continuity.

[0005] The technical solution of the present invention is:

[0006] A piston motion controller is used in a submersible piston cooperative drive engine and is linked with a piston fixed angle control switch. Two piston motion controllers and two piston fixed angle control switches are installed in the piston cylinder of each submersible piston cooperative drive engine. A piston motion controller and a piston fixed angle control switch form a group and are fixedly mounted on the same base on the inner wall of the two ends of the piston cylinder. The base is fixedly mounted on the two ends of the piston cylinder and the end support mechanism. The piston motion controller includes a piston control top, a piston control column, a control column limit plate, a control column sleeve, a sleeve spring, a control column stop frame, a clamping crank arm, a crank arm sliding sleeve, a crank arm control ring, a crank arm rotating shaft, a crank arm support column, a crank arm connecting shaft, a crank arm pulley, a crank arm spring and a base, wherein:

[0007] The piston control top is a pancake-shaped mechanism fixed on the top of the piston control column and corresponding to and colliding with the submersible piston top of the submersible piston, and controlling the movement range of the piston control column. A high-strength and high-wear-resistant buffer layer is installed at the contact portion between the piston control top and the submersible piston top. Under the collision pressure of the submersible piston, when the piston control top contacts the collar of the control column stopper, the piston control top and the piston control column stop moving.

[0008] The piston control column is located in the control column sleeve and is connected to the fixed piston control top and the columnar mechanism that bears the impact pressure of the submerged piston;

[0009] The control column sleeve is a cylindrical mechanism that supports and stabilizes the piston control column to move up and down. A sleeve spring is installed at the bottom of the control column sleeve. The sleeve spring is used to release the impact of the submerged piston on the piston control column and provide an initial thrust for the submerged piston to start moving. The control column sleeve is fixed on the base, and the base is fixed on the piston cylinder end and the end support mechanism of the submerged piston cooperatively driving the engine;

[0010] The control column limit plate is a disc-shaped component fixedly mounted on the piston control column. The control column limit plate is limited by the control column stop frame. When the piston control column moves upward, the control column limit plate moves upward accordingly. When the control column limit plate contacts the collar of the control column stop frame, the piston control column stops moving.

[0011] The control column retaining frame is a mechanism composed of two grooved rods and sleeve rings at their ends. One end of the two grooved rods is symmetrically connected and fixed to the outside of the control column sleeve, and the other end is symmetrically connected and fixed to the sleeve ring. The sleeve ring of the control column retaining frame is located between the piston control top and the control column limit plate. A linear bearing is installed in the sleeve ring. The piston control column is connected in series in the linear bearing of the sleeve ring and can slide up and down freely in the linear bearing. When the piston control column moves downward, the sleeve ring of the control column retaining frame blocks the piston control top and the piston control column stops moving. When the piston control column moves upward, the sleeve ring of the control column retaining frame blocks the control column limit plate and the piston control column stops moving. This makes the control column retaining frame limit the movement range of the piston control column, thereby ensuring the stability and reliability of the movement of the piston control column.

[0012] The clamping crank arms are two curved rod-shaped mechanisms for clamping and controlling the submerged floating piston. The shape, size, length and weight of the two symmetrically installed clamping crank arms are the same. The bending parts of the two clamping crank arms are supported and connected by the crank arm rotating shafts at the ends of the two crank arm support columns, respectively. The clamping crank arms can rotate around the crank arm rotating shafts, and the two crank arm support columns are fixed on the base. The ends of the clamping crank arms located on both sides of the piston control column are respectively connected to the crank arm connecting shafts on both sides of the crank arm sliding sleeve. When the crank arm sliding sleeve slides up and down along the piston control column, the clamping ends of the two clamping crank arms are opened and closed to realize the release and locking of the submerged floating piston. Crank arm pulleys are installed at the clamping ends of the two clamping crank arms to stably and freely lock and release the submerged floating piston. The present invention has designed and developed two types of clamping crank arms, namely, connecting rod type clamping crank arms and linear bearing type clamping crank arms. A piston motion controller can select one of the above two types of clamping crank arms. There are two ways for the clamping crank arm to clamp the submersible piston, namely, the submersible piston end clamping method and the submersible piston shoulder clamping method. The submersible piston end clamping method is a method of locking and releasing the submersible piston by clamping the piston clamping grooves at both ends or the neck of the submersible piston, and the submersible piston shoulder clamping method is a method of locking and releasing the submersible piston by clamping the piston clamping grooves at the shoulders of the submersible piston;

[0013] The crank arm sliding sleeve comprises a linear bearing and a crank arm connecting shaft symmetrically installed on both sides thereof, the crank arm connecting shaft comprises a bearing, a bearing shaft and a bearing support seat, the inner ring of the bearing is serially fixed to the middle part of the bearing shaft, the two ends of the bearing shaft are mounted and fixed on two support frames at the ends of the bearing support seat, the other end of the bearing support seat is connected and fixed to the bearing sleeve of the linear bearing, the linear bearing is serially connected to the piston control column and can slide up and down along the piston control column, the ends of the two clamping crank arms are connected to the outer rings of the bearings of the two symmetrically installed crank arm connecting shafts and can rotate around the bearings;

[0014] The crank arm control ring is a ring-shaped component installed and fixed on the crank arm sliding sleeve and used to drive the clamping crank arm to release the submerged floating piston. The starting arm of the piston fixed angle control switch is connected to the crank arm control ring. When the submerged floating piston needs to start moving, the starting arm drives the crank arm control ring together with the crank arm sliding sleeve to move toward the submerged floating piston. The clamping crank arm connected to the crank arm sliding sleeve opens the two clamping ends of the clamping crank arm through the lever action, releases the submerged floating piston, and allows the submerged floating piston to start moving.

[0015] The crank arm spring is symmetrically installed and fixed between two clamping crank arms close to the piston control column and the corresponding lower part of the crank arm support column or the base. The crank arm spring always pulls the clamping ends of the two clamping crank arms to clamp the submersible piston, so that the submersible piston cannot escape the control of the piston motion controller.

[0016] The piston control column is a columnar structure that bears and slowly releases the impact pressure generated on the piston control top when the submerged piston quickly floats up in the piston cylinder, and provides initial thrust when the submerged piston starts to move. The thickness and shape of various parts of the entire piston control column can be different. The lower end of the piston control column is placed in the control column sleeve, and a linear bearing is installed in the control column sleeve. The piston control column, as a smooth straight column, can slide up and down stably and flexibly in the matching linear bearing.

[0017] The control column sleeve is a straight cylindrical structure that supports and stabilizes the piston control column. A sleeve spring is installed at the bottom of the control column sleeve. When the submerged piston contacts and squeezes the piston control top at a certain speed, the buffer layer of the piston control top slowly releases the instantaneous impact of the submerged piston. At the same time, the piston control top and the piston control column immediately move toward the bottom of the control column sleeve and squeeze the sleeve spring, so that the elastic potential energy of the sleeve spring increases rapidly. When the clamping crank arm releases the submerged piston, the sleeve spring applies an initial thrust to the submerged piston through the piston control column under the action of the accumulated elastic potential energy, so that the submerged piston quickly leaves the piston control top. The control column sleeve is also tightly connected to the control column retaining frame to ensure the stability of the control column retaining frame.

[0018] The clamping crank arm is a bent rod-shaped mechanism for clamping and controlling the start and stop state of the submerged piston. The present invention creates two types of clamping crank arms, namely, a connecting rod type clamping crank arm and a linear bearing type clamping crank arm, wherein:

[0019] The connecting rod type clamping crank arm refers to adding a connecting rod between the end of the clamping crank arm and the crank arm sliding sleeve, the two ends of the connecting rod are connected to the crank arm connecting shaft, and the crank arm rotating shaft located at the bending part of the clamping crank arm is moved up to the upper part of the bending part of the clamping crank arm, so that when the crank arm sliding sleeve moves up and down, the distance between the crank arm rotating shaft and the crank arm connecting shaft of the crank arm sliding sleeve can be changed by the connecting rod drive, so as to achieve the purpose of effectively closing and opening the clamping ends of the two clamping crank arms;

[0020] The linear bearing type clamping crank arm refers to dividing the clamping crank arm between the crank arm rotating shaft and the crank arm sliding sleeve into two sections, and inserting the two sections of the clamping crank arm into the same linear bearing, so that when the crank arm sliding sleeve moves up and down, the two sections of the clamping crank arm can be freely extended and retracted in the linear bearing, thereby changing the length of the clamping crank arm between the crank arm rotating shaft and the crank arm sliding sleeve, and achieving the purpose of effectively closing and opening the clamping ends of the two clamping crank arms;

[0021] The clamping crank arm is a mechanism that uses the lever principle to convert the vertical movement of the crank arm sliding sleeve into the horizontal movement of the clamping end of the clamping crank arm. When the crank arm sliding sleeve moves up and down, the length of the clamping crank arm between the crank arm rotating shaft and the crank arm sliding sleeve changes continuously. The connecting rod type clamping crank arm and the linear bearing type clamping crank arm just solve the problem of the continuous change of the length of the clamping crank arm, so that the clamping ends of the two clamping crank arms can be effectively closed and opened. A piston motion controller can select one of the connecting rod type clamping crank arm and the linear bearing type clamping crank arm.

[0022] The crank arm shaft is a rotating mechanism that connects and supports the clamping crank arm and is installed at the end of the crank arm support column. The crank arm shaft includes a bearing, a bearing shaft and a bearing support seat. The bearing shaft is a cylindrical rod-shaped component, and its diameter is exactly the same as the diameter of the inner edge of the bearing inner ring. The bearing shaft is inserted into the bearing inner ring and is tightly connected to the bearing inner ring. The two ends of the bearing shaft are supported and fixed by two bearing support seats at the end of the crank arm support column. A circular hole with exactly the same diameter as the outer edge of the bearing outer ring is cut on the clamping crank arm or at the turning part of the clamping crank arm. The circular hole of the clamping crank arm is inserted into the outer ring of the bearing and is tightly connected to the outer ring of the bearing, so that the clamping crank arm can rotate under the support of the bearing.

[0023] The crank arm spring is a spring whose one end is connected and fixed to the clamping crank arm near the crank arm connecting shaft, and the other end is connected and fixed to the crank arm support column near the base or the base. One or more crank arm springs are symmetrically installed between each clamping crank arm and the corresponding crank arm support column or base, but the mechanical properties, length, size, shape and weight of the crank arm spring installed on one clamping crank arm are the same as those of the crank arm spring installed on the corresponding other clamping crank arm; the crank arm spring always pulls the clamping end of the clamping crank arm to tightly grasp the piston clamping groove of the submersible piston, so that the submersible piston remains in a stopped state, but the combined elastic force of all the crank arm springs in the movement direction of the crank arm sliding sleeve must be smaller than the piston fixed angle control switch starting arm. The driving force applied to the crank arm control ring enables the starting arm of the piston fixed angle control switch to drive the clamping ends of the two clamping crank arms to open and release the submerged piston, allowing the submerged piston to start moving; if the combined elastic force of all the crank arm springs in the movement direction of the crank arm sliding sleeve is greater than the driving force applied to the crank arm control ring by the starting arm of the piston fixed angle control switch, the starting arm of the piston fixed angle control switch cannot drive the crank arm sliding sleeve to move, thereby, the clamping ends of the two clamping crank arms cannot open, and the submerged piston cannot start moving.

[0024] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0025] (1) The present invention creates a method of combining a piston control top and a piston control column to bear the impact pressure of the submerged piston, and designs a control column sleeve to stabilize the piston control column, so that the piston control top, the piston control column, the control column sleeve and the submerged piston are located on the same straight line, forming a linear control system centered on the piston control column, which has good effectiveness, accuracy and stability in adapting to and controlling the linear impact movement of the submerged piston, and has good flexibility in the connection and coordinated movement of other control mechanisms.

[0026] (2) The present invention creates a key mechanism of a control column sleeve and a sleeve spring. When the submersible piston quickly collides with the piston control top and the piston control column, the sleeve spring can not only slowly release the instantaneous impact force exerted by the submersible piston, but more importantly, under the impact of the submersible piston, the sleeve spring accumulates a large amount of elastic potential energy. When the submersible piston starts to move, the sleeve spring provides an initial driving force to the submersible piston under the action of the accumulated elastic potential energy, allowing the submersible piston to start quickly. In this way, the kinetic energy of the submersible piston is fully and effectively utilized, energy loss is avoided, the operating speed and efficiency of the submersible piston are greatly improved, and the speed of the engine driven by the submersible piston is improved.

[0027] (3) The present invention creates a limiting system in which three mechanisms, namely, a piston control top, a control column limit plate and a control column retaining frame, cooperate with each other. After accurately calculating the range of up and down movement of the piston control column, the positions of the piston control top, the control column limit plate and the control column retaining frame are accurately installed, so that the piston control column moves within the range between the piston control top and the control column limit plate, thereby greatly improving the accuracy, stability and reliability of the movement of each control mechanism.

[0028] (4) The present invention adopts an end clamping method and a shoulder clamping method to lock and release the submersible piston, and creates a complete clamping system consisting of a clamping crank arm, a crank arm sliding sleeve, a crank arm control ring, a crank arm rotating shaft, a crank arm support column, a crank arm connecting shaft, a crank arm spring and a crank arm pulley. The method is simple, effective and flexible. The submersible piston is locked and released by clamping, and is linked with the piston fixed angle control switch to achieve accurate control of the submersible piston, greatly improving the smoothness and stability of the entire control process; the present invention creates two types of clamping crank arms, namely a connecting rod type clamping crank arm and a linear bearing type clamping crank arm, which provide more choices for the piston motion controller of the submersible piston cooperative drive engine of different powers.

[0029] (5) The piston motion controller created by the present invention is a purely mechanical control system. The real-time linkage between the piston motion controller and the piston fixed angle control switch realizes the automation and precision of the submersible piston control, and the performance is very stable and reliable. The entire piston motion controller does not use any electromagnetic control device and electronic components, is not affected by the performance of any electromagnetic control device and electronic components, and does not consume any electric energy. Therefore, the present invention has good practicality.

The materials and components 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 and components from other countries. Therefore, there are no trade barriers to the industrial development of the present invention.

DETAILED DESCRIPTION

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0039] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a piston motion controller, which is applied to a submersible piston cooperative drive engine and is linked with a piston fixed angle control switch. Two piston motion controllers and two piston fixed angle control switches are installed in the piston cylinder of each submersible piston cooperative drive engine. A piston motion controller and a piston fixed angle control switch form a group, which are fixedly mounted on the same base on the inner wall of the two ends of the piston cylinder, and the base is fixedly mounted on the two ends of the piston cylinder and the end support mechanism; the piston motion controller includes a piston control top 1, a piston control column 2, a control column limit plate 3, a control column sleeve 4, a sleeve spring 5, a control column stop frame 6, a clamping crank arm 7, a crank arm sliding sleeve 8, a crank arm control ring 15, a crank arm rotating shaft 9, a crank arm support column 10, a crank arm connecting shaft 11, a crank arm spring 12, a crank arm pulley 13 and a base 14, wherein:

[0040] See also Figure 1 and Figure 2 The piston control top 1 is a pancake-shaped mechanism installed and fixed on the top of the piston control column 2 and corresponds to and collides with the submerged piston top of the submerged piston, and controls the movement range of the piston control column 2. A high-strength and high-wear-resistant buffer layer is installed at the contact portion between the piston control top 1 and the submerged piston top. Under the collision pressure of the submerged piston, when the piston control top 1 contacts the collar of the control column stop frame 6, the piston control top 1 and the piston control column 2 stop moving;

[0041] See also Figure 1 and Figure 2 The piston control column 2 is located in the control column sleeve 4 and is connected to the fixed piston control top 1 and the columnar mechanism that bears the impact pressure of the submerged piston;

[0042] See also Figure 1 and Figure 2 The control column sleeve 4 is a cylindrical mechanism that carries and stabilizes the piston control column 2 to move up and down. A sleeve spring 5 is installed at the bottom of the control column sleeve 4. The sleeve spring 5 is used to release the impact of the submerged piston on the piston control column 2 and provide an initial thrust for the submerged piston to start moving. The control column sleeve 4 is fixed on the base 14, and the base 14 is fixed on the piston cylinder end and the end support mechanism of the submerged piston cooperative driving engine;

[0043] See also Figure 1 and Figure 2 The control column limit plate 3 is a disc-shaped component installed and fixed on the piston control column 2. The control column limit plate 3 is limited by the control column stop frame 6. When the piston control column 2 moves upward, the control column limit plate 3 moves upward accordingly. When the control column limit plate 3 contacts the collar of the control column stop frame 6, the piston control column 2 stops moving.

[0044] See also Figure 1 and Figure 2 The control column retaining frame 6 is a mechanism composed of two grooved rods and their end sleeve rings. One end of the two grooved rods is symmetrically connected and fixed to the outer side of the control column sleeve 4, and the other end is symmetrically connected and fixed to the sleeve ring. The sleeve ring of the control column retaining frame 6 is located between the piston control top 1 and the control column limit plate 3. A linear bearing is installed in the sleeve ring. The piston control column 2 is connected in series in the linear bearing of the sleeve ring and can slide up and down freely in the linear bearing. When the piston control column 2 moves downward, the sleeve ring of the control column retaining frame 6 blocks the piston control top 1, and the piston control column 2 stops moving. When the piston control column 2 moves upward, the sleeve ring of the control column retaining frame 6 blocks the control column limit plate 3, and the piston control column 2 stops moving. This makes the control column retaining frame 6 limit the movement range of the piston control column 2, thereby greatly improving the stability and reliability of the movement of the piston control column 2.

[0045] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The clamping crank arms 7 are two curved rod-shaped mechanisms for clamping and controlling the submerged floating piston. The two symmetrically installed clamping crank arms 7 have the same shape, size, length and weight. The curved parts of the two clamping crank arms 7 are supported and connected by the crank shafts 9 at the ends of the two crank support columns 10. The clamping crank arms 7 can rotate around the crank shafts 9. The two crank support columns 10 are fixed on the base 14. The ends of the clamping crank arms 7 located on both sides of the piston control column 2 are respectively connected to the crank connecting shafts 11 on both sides of the crank sliding sleeve 8. When the crank sliding sleeve 8 slides up and down along the piston control column 2, the clamping ends of the two clamping crank arms 7 are opened and closed to realize the release and locking of the submerged floating piston. Crank pulleys 13 are installed at the clamping ends of the two clamping crank arms 7 to stably and freely lock and release the submerged floating piston. The present invention has designed and developed two types of clamping crank arms, namely, a connecting rod type clamping crank arm and a linear bearing type clamping crank arm. A piston motion controller can select one of the above two types of clamping crank arms. There are two ways for the clamping crank arm 7 to clamp the submersible piston, namely, the submersible piston end clamping method and the submersible piston shoulder clamping method. The submersible piston end clamping method is a method of locking and releasing the submersible piston by clamping the piston clamping grooves at the ends or neck of the submersible piston. The submersible piston shoulder clamping method is a method of locking and releasing the submersible piston by clamping the piston clamping grooves at the shoulders of the submersible piston.

[0046] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The crank arm sliding sleeve 8 includes a linear bearing and a crank arm connecting shaft 11 symmetrically installed on both sides thereof. The crank arm connecting shaft 11 includes a bearing, a bearing shaft and a bearing support seat. The inner ring of the bearing is connected and fixed in series to the middle of the bearing shaft. Both ends of the bearing shaft are fixed to two support frames at the ends of the bearing support seat. The other end of the bearing support seat is connected and fixed to the bearing sleeve of the linear bearing. The linear bearing is connected in series to the piston control column 2 and can slide up and down along the piston control column 2. The ends of the two clamping crank arms 7 are connected to the outer rings of the bearings of the two symmetrically installed crank arm connecting shafts 11 and can rotate around the bearings.

[0047] See also Figure 3 and Figure 4 The crank arm control ring 15 is a ring-shaped component fixed on the crank arm sliding sleeve 8 and used to drive the clamping crank arm 7 to release the submerged floating piston. The starting arm of the piston fixed angle control switch is connected to the crank arm control ring 15. When the submerged floating piston needs to start moving, the starting arm drives the crank arm control ring 15 together with the crank arm sliding sleeve 8 to move toward the submerged floating piston. The clamping crank arm 7 connected to the crank arm sliding sleeve 8 opens the two clamping ends of the clamping crank arm 7 through the lever action, releases the submerged floating piston, and allows the submerged floating piston to start moving.

[0048] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The crank arm spring 12 is symmetrically installed and fixed between two clamping crank arms 7 close to the piston control column 2 and the corresponding lower part of the crank arm support column 10 or the base 14. The crank arm spring 12 always pulls the clamping ends of the two clamping crank arms 7 to clamp the submerged floating piston, so that the submerged floating piston cannot escape the control of the piston motion controller.

[0049] See also Figure 1 and Figure 2 The piston control column 2 is a columnar structure that bears and slowly releases the impact pressure generated by the submerged piston on the piston control top 1 when the submerged piston quickly floats up in the piston cylinder, and provides an initial thrust when the submerged piston starts to move. The thickness and shape of each part of the entire piston control column 2 can be different. The lower end of the piston control column 2 is placed in the control column sleeve 4, and a linear bearing is installed in the control column sleeve 4. The piston control column 2, as a smooth straight column, can slide up and down stably and flexibly in the matching linear bearing.

[0050] See also Figure 1 and Figure 2The control column sleeve 4 is a straight cylindrical structure that carries and stabilizes the piston control column 2. A sleeve spring 5 is installed at the bottom of the control column sleeve 4. When the submerged piston contacts and squeezes the piston control top 1 at a certain speed, the buffer layer of the piston control top 1 slowly releases the instantaneous impulse of the submerged piston. At the same time, the piston control top 1 and the piston control column 2 immediately move to the bottom of the control column sleeve 4 and squeeze the sleeve spring 5, so that the elastic potential energy of the sleeve spring 5 increases rapidly. When the clamping crank arm 7 releases the submerged piston, the sleeve spring 5 applies an initial thrust to the submerged piston through the piston control column 2 under the action of the accumulated elastic potential energy, so that the submerged piston quickly leaves the piston control top 1. The control column sleeve 4 is also tightly connected to the control column retaining frame 6 to ensure the stability of the control column retaining frame 6.

[0051] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The clamping crank arm 7 is a bent rod-shaped mechanism for clamping and controlling the start and stop state of the submerged piston. The present invention creates two types of clamping crank arms 7, namely, a connecting rod type clamping crank arm 7 and a linear bearing type clamping crank arm 7, wherein:

[0052] See also Figure 3 The connecting rod type clamping crank arm 7 means that a connecting rod 16 is added between the end of the clamping crank arm 7 and the crank arm sliding sleeve 8, and the two ends of the connecting rod 16 are connected to the crank arm connecting shaft 11, and the crank arm rotating shaft 9 located at the bending part of the clamping crank arm 7 is moved up to the upper part of the bending part of the clamping crank arm 7, so that when the crank arm sliding sleeve 8 moves up and down, the distance between the crank arm rotating shaft 9 and the crank arm connecting shaft 11 of the crank arm sliding sleeve 8 can be changed by driving the connecting rod 16, so as to achieve the purpose of effectively closing and opening the clamping ends of the two clamping crank arms 7;

[0053] See also Figure 4 The linear bearing type clamping crank arm 7 refers to dividing the clamping crank arm 7 between the crank arm rotating shaft 9 and the crank arm sliding sleeve 8 into two sections, and inserting the two sections of the clamping crank arm 7 into the same linear bearing 17, so that when the crank arm sliding sleeve 8 moves up and down, the two sections of the clamping crank arm 7 can be freely extended and retracted in the linear bearing 17, thereby changing the length of the clamping crank arm 7 between the crank arm rotating shaft 9 and the crank arm sliding sleeve 8, and achieving the purpose of effectively closing and opening the clamping ends of the two clamping crank arms 7;

[0054] See also Figure 3 and Figure 4The clamping crank arm 17 is a mechanism that uses the lever principle to convert the vertical movement of the crank arm sliding sleeve 8 into the horizontal movement of the clamping end of the clamping crank arm 7. When the crank arm sliding sleeve 8 moves up and down, the length of the clamping crank arm 7 between the crank arm rotating shaft 9 and the crank arm sliding sleeve 8 changes continuously. The connecting rod type clamping crank arm and the linear bearing type clamping crank arm just solve the problem of the continuous change of the length of the clamping crank arm, so that the clamping ends of the two clamping crank arms 7 can be effectively closed and opened. A piston motion controller can select one of the connecting rod type clamping crank arm and the linear bearing type clamping crank arm.

[0055] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The crank arm shaft 9 is a rotating mechanism for connecting and supporting the clamping crank arm 7, and is installed at the end of the crank arm support column 10. The crank arm shaft 9 includes a bearing, a bearing shaft and a bearing support seat. The bearing shaft is a cylindrical rod-shaped component, and its diameter is exactly the same as the diameter of the inner edge of the bearing inner ring. The bearing shaft is inserted into the bearing inner ring and is tightly connected to the bearing inner ring. The two ends of the bearing shaft are supported and fixed by two bearing support seats at the end of the crank arm support column 10. A circular hole with a diameter exactly the same as the outer edge of the bearing outer ring is cut on the clamping crank arm 7 or at the turning part of the clamping crank arm 7. The circular hole of the clamping crank arm 7 is inserted into the outer ring of the bearing and is tightly connected to the outer ring of the bearing, so that the clamping crank arm 7 can rotate under the support of the bearing.

[0056] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The crank arm spring 12 is a spring whose one end is connected and fixed to the clamping crank arm 7 near the crank arm connecting shaft 11, and the other end is connected and fixed to the crank arm support column 10 near the base 14 or the base 14. One or more crank arm springs 12 are symmetrically installed between each clamping crank arm 7 and the corresponding crank arm support column 10 or base 14, but the mechanical properties, length, size, shape and weight of the crank arm spring 12 installed on one clamping crank arm 7 are the same as those of the crank arm spring 12 installed on the corresponding other clamping crank arm 7. The crank arm spring 12 always pulls the clamping end of the clamping crank arm 7 to tightly grasp the piston clamping groove of the submerged floating piston, so that the submerged floating piston remains in a stopped state, but the combined elastic force of all the crank arm springs 12 in the movement direction of the crank arm sliding sleeve 8 must be less than the piston fixed angle control opening. The driving force applied by the starting arm of the piston fixed angle control switch to the crank arm control ring 15 enables the starting arm of the piston fixed angle control switch to drive the clamping ends of the two clamping crank arms 7 to open and release the submerged piston, allowing the submerged piston to start moving; if the combined elastic force of all the crank arm springs 12 in the movement direction of the crank arm sliding sleeve 8 is greater than the driving force applied by the starting arm of the piston fixed angle control switch to the crank arm control ring 15, the starting arm of the piston fixed angle control switch cannot drive the crank arm sliding sleeve 8 to move, thereby, the clamping ends of the two clamping crank arms 7 cannot be opened, and the submerged piston cannot start moving.

[0057] The working process of the present invention is further described below:

[0058] The angle between the piston cylinder of the engine driven by the submersible piston and the vertical line of the engine center axis is set as the starting angle for the submersible piston to start moving. When the piston cylinder rotates in the clockwise direction, the submersible piston in the piston cylinder also rotates in the clockwise direction. When the piston cylinder rotates to the position corresponding to the starting angle below the horizontal plane on the right side of the engine center axis, the starting arm of the piston fixed angle control switch located at the outer end of the piston cylinder instantly drives the crank arm control ring 15 of the piston motion controller together with the crank arm sliding sleeve 8 to move in the direction of the submersible piston. The sliding sleeve 8 instantly drives the clamping crank arms 7 on both sides thereof to open outwards, so that the clamping ends of the two clamping crank arms 7 leave the crank arm clamping grooves of the submerged piston. Under the elastic thrust of the sleeve spring 5 and the buoyancy of the liquid, the submerged piston quickly moves toward the inner end of the piston cylinder. When the submerged piston reaches the locking position of the clamping crank arms 7 of the piston motion controller at the inner end of the piston cylinder, the two clamping crank arms 7 of the piston motion controller immediately and automatically lock the submerged piston, and the submerged piston stops moving. As the piston cylinder continues to rotate, when the piston cylinder rotates to the left side of the center axis of the engine, the submerged piston stops moving. When the position corresponds to the starting angle above the horizontal plane, the starting arm of the piston fixed angle control switch located at the inner end of the piston cylinder instantly drives the crank arm control ring 15 of the piston motion controller together with the crank arm sliding sleeve 8 to move toward the submerged piston. The crank arm sliding sleeve 8 instantly drives the clamping crank arms 7 on both sides thereof to open outward, so that the clamping ends of the two clamping crank arms 7 leave the crank arm clamping grooves of the submerged piston. The submerged piston moves rapidly toward the outer end of the piston cylinder under the elastic thrust of the sleeve spring 5 and the buoyancy of the liquid. When the submerged piston reaches the piston at the outer end of the piston cylinder, When the motion controller clamps the crank arm 7 in the locking position, the two clamping crank arms 7 of the piston motion controller immediately and automatically lock the submerged piston, and the submerged piston stops moving; during the continuous rotation of the piston cylinder, the submerged pistons in each piston cylinder are controlled by the piston motion controller and the piston fixed angle control switch, and reciprocate in their respective piston cylinders in turn, so that the submerged pistons on the left and right sides of the vertical line of the engine center axis produce torque difference and torque difference, thereby driving the piston cylinder together with the engine rotating disk and the engine center axis to rotate and output power to the outside. When the piston cylinder rotates in the counterclockwise direction, the working process of the piston motion controller is the same.

[0059] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.

Claims

1. A piston motion controller, used in a submersible piston cooperative drive engine, characterized in that: It includes a piston control top, a piston control column, a control column limit plate, a control column sleeve, a sleeve spring, a control column retaining frame, a clamping crank arm, a crank arm sliding sleeve, a crank arm control ring, a crank arm rotating shaft, a crank arm support column, a crank arm connecting shaft, a crank arm pulley, a crank arm spring and a base, wherein: The piston control top is a pancake-shaped mechanism fixed on the top of the piston control column and corresponding to and colliding with the submersible piston top of the submersible piston, and controlling the movement range of the piston control column. A high-strength and high-wear-resistant buffer layer is installed at the contact portion between the piston control top and the submersible piston top. Under the collision pressure of the submersible piston, when the piston control top contacts the collar of the control column stopper, the piston control top and the piston control column stop moving. The piston control column is located in the control column sleeve and is connected to the fixed piston control top and the columnar mechanism that bears the impact pressure of the submerged piston; The control column sleeve is a cylindrical mechanism that supports and stabilizes the piston control column to move up and down. A sleeve spring is installed at the bottom of the control column sleeve. The sleeve spring is used to release the impact of the submerged piston on the piston control column and provide an initial thrust for the submerged piston to start moving. The control column sleeve is fixed on the base, and the base is fixed on the piston cylinder end and the end support mechanism of the submerged piston cooperatively driving the engine; The control column limit plate is a disc-shaped component fixedly mounted on the piston control column. The control column limit plate is limited by the control column stop frame. When the piston control column moves upward, the control column limit plate moves upward accordingly. When the control column limit plate contacts the collar of the control column stop frame, the piston control column stops moving. The control column retaining frame is a mechanism composed of two grooved rods and sleeve rings at their ends. One end of the two grooved rods is symmetrically connected and fixed to the outside of the control column sleeve, and the other end is symmetrically connected and fixed to the sleeve ring. The sleeve ring of the control column retaining frame is located between the piston control top and the control column limit plate. A linear bearing is installed in the sleeve ring. The piston control column is connected in series in the linear bearing of the sleeve ring and can slide up and down freely in the linear bearing. When the piston control column moves downward, the sleeve ring of the control column retaining frame blocks the piston control top and the piston control column stops moving. When the piston control column moves upward, the sleeve ring of the control column retaining frame blocks the control column limit plate and the piston control column stops moving. This makes the control column retaining frame limit the movement range of the piston control column. The clamping crank arms are two curved rod-shaped mechanisms for clamping and controlling the submerged floating pistons. The two symmetrically installed clamping crank arms are of the same shape, size, length and weight. The curved parts of the two clamping crank arms are respectively supported and connected by the crank shafts at the ends of the two crank support columns. The clamping crank arms can rotate around the crank shafts. The two crank support columns are fixed on the base. The ends of the clamping crank arms on both sides of the piston control column are respectively connected to the crank connecting shafts on both sides of the crank sliding sleeve. When the crank sliding sleeve slides up and down along the piston control column, the clamping ends of the two clamping crank arms open and close to loosen and lock the submerged floating piston. The ends of the clamping ends are all equipped with crank pulleys so as to stably and freely lock and release the submersible piston. The clamping crank arms include connecting rod type clamping crank arms and linear bearing type clamping crank arms. A piston motion controller can select one of the two clamping crank arms. There are two ways for the clamping crank arms to clamp the submersible piston, namely, the submersible piston end clamping method and the submersible piston shoulder clamping method. The submersible piston end clamping method is a method of locking and releasing the submersible piston by clamping the piston clamping grooves at the two ends or neck of the submersible piston. The submersible piston shoulder clamping method is a method of locking and releasing the submersible piston by clamping the piston clamping grooves at the shoulders of the submersible piston. The crank arm sliding sleeve is composed of a linear bearing and crank arm connecting shafts symmetrically installed on both sides, and is connected in series to the piston control column. It is a motion mechanism that can slide up and down along the piston control column. The two crank arm connecting shafts are symmetrically installed and fixed on the bearing sleeves of the linear bearings. The two clamping crank arm ends are respectively connected to the two crank arm connecting shafts and can rotate around the crank arm connecting shafts. The crank arm control ring is a ring-shaped component installed and fixed on the crank arm sliding sleeve and used to drive the clamping crank arm to release the submerged floating piston. The starting arm of the piston fixed angle control switch is connected to the crank arm control ring. When the submerged floating piston needs to start moving, the starting arm drives the crank arm control ring together with the crank arm sliding sleeve to move toward the submerged floating piston. The clamping crank arm connected to the crank arm sliding sleeve opens the two clamping ends of the clamping crank arm through the lever action, releases the submerged floating piston, and allows the submerged floating piston to start moving. The crank arm spring is symmetrically installed and fixed between two clamping crank arms close to the piston control column and the corresponding lower part of the crank arm support column or the base. The crank arm spring always pulls the clamping ends of the two clamping crank arms to clamp the submersible piston, so that the submersible piston cannot escape the control of the piston motion controller.

2. The piston motion controller according to claim 1, characterized in that: The piston control column is a columnar structure that bears and slowly releases the impact pressure generated on the piston control top when the submerged piston quickly floats up in the piston cylinder, and provides initial thrust when the submerged piston starts to move. The thickness and shape of various parts of the entire piston control column can be different. The lower end of the piston control column is placed in the control column sleeve, and a linear bearing is installed in the control column sleeve. The piston control column, as a smooth straight column, can slide up and down stably and flexibly in the matching linear bearing.

3. The piston motion controller according to claim 1, characterized in that: The control column sleeve is a straight cylindrical structure that supports and stabilizes the piston control column. A sleeve spring is installed at the bottom of the control column sleeve. When the submerged piston contacts and squeezes the piston control top at a certain speed, the buffer layer of the piston control top slowly releases the instantaneous impact of the submerged piston. At the same time, the piston control top and the piston control column immediately move toward the bottom of the control column sleeve and squeeze the sleeve spring, so that the elastic potential energy of the sleeve spring increases rapidly. When the clamping crank arm releases the submerged piston, the sleeve spring applies an initial thrust to the submerged piston through the piston control column under the action of the accumulated elastic potential energy, so that the submerged piston quickly leaves the piston control top. The control column sleeve is also tightly connected to the control column retaining frame to ensure the stability of the control column retaining frame.

4. The piston motion controller according to claim 1, characterized in that: The clamping crank arm is a bent rod-shaped mechanism for clamping and controlling the start and stop state of the submerged piston. The clamping crank arm includes a connecting rod type clamping crank arm and a linear bearing type clamping crank arm, wherein: The connecting rod type clamping crank arm refers to adding a connecting rod between the end of the clamping crank arm and the crank arm sliding sleeve, the two ends of the connecting rod are connected to the crank arm connecting shaft, and the crank arm rotating shaft located at the bending part of the clamping crank arm is moved up to the upper part of the bending part of the clamping crank arm, so that when the crank arm sliding sleeve moves up and down, the distance between the crank arm rotating shaft and the crank arm connecting shaft of the crank arm sliding sleeve can be changed by the connecting rod drive, so as to achieve the purpose of effectively closing and loosening the two clamping crank arms; The linear bearing type clamping crank arm refers to dividing the clamping crank arm between the crank arm rotating shaft and the crank arm sliding sleeve into two sections, and inserting the two sections of the clamping crank arm into the same linear bearing, so that when the crank arm sliding sleeve moves up and down, the two sections of the clamping crank arm can be freely extended and retracted in the linear bearing, thereby changing the length of the clamping crank arm between the crank arm rotating shaft and the crank arm sliding sleeve, and achieving the purpose of effectively closing and loosening the two clamping crank arms.

5. The piston motion controller according to claim 1, characterized in that: The crank arm shaft is a rotating mechanism that connects and supports the clamping crank arm and is installed at the end of the crank arm support column. The crank arm shaft includes a bearing, a bearing shaft and a bearing support seat. The bearing shaft is a cylindrical rod-shaped component, and its diameter is exactly the same as the diameter of the inner edge of the bearing inner ring. The bearing shaft is inserted into the bearing inner ring and is tightly connected to the bearing inner ring. The two ends of the bearing shaft are supported and fixed by two bearing support seats at the end of the crank arm support column. A circular hole with exactly the same diameter as the outer edge of the bearing outer ring is cut on the clamping crank arm or at the turning part of the clamping crank arm. The circular hole of the clamping crank arm is inserted into the outer ring of the bearing and is tightly connected to the outer ring of the bearing, so that the clamping crank arm can rotate under the support of the bearing.

6. The piston motion controller according to claim 1, characterized in that: The crank arm spring is a spring whose one end is connected and fixed to a clamping crank arm near the crank arm connecting axis, and the other end is connected and fixed to a crank arm support column near the base or on the base. One or more crank arm springs are symmetrically installed between each clamping crank arm and the corresponding crank arm support column or base, but the crank arm spring installed on one clamping crank arm and the crank arm spring installed on the corresponding other clamping crank arm have the same mechanical properties, length, size, shape and weight. The crank arm spring always pulls the clamping end of the clamping crank arm to tightly clamp the piston clamping groove of the submersible piston, so that the submersible piston remains in a stopped state, but the combined elastic force of all the crank arm springs in the direction of movement of the submersible piston is less than the driving force applied to the crank arm control ring by the starting arm of the piston fixed angle control switch, so that the starting arm of the piston fixed angle control switch can drive the clamping ends of the two clamping crank arms to open, and release the submersible piston, allowing the submersible piston to start moving.
