Description

Technical Field

[0001] The invention belongs to the field of engine systems, and in particular relates to a piston fixed angle control switch and a submersible piston fixed angle control method. 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 burning of a large amount of fossil energy such as coal, oil and natural gas. The use of electric motors requires the consumption of a large amount of electricity, and more than 70% of electricity comes from thermal power plants. The production of this electricity also requires the burning 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, seriously threatening human safety and survival; although nuclear engines are a clean power system, nuclear engines require the consumption of expensive nuclear materials, and once nuclear leakage and other incidents occur, it will cause great losses and damage to life, property and ecological environment in the surrounding areas; hydropower, wind power, solar power, etc. can produce a large amount of electricity to provide energy for electric motors, but hydropower, wind power, solar power, etc. are directly affected by factors such as weather, climate, season, day and night changes and natural environmental conditions, resulting in instability of the electricity produced by these power generation systems and low quality of electricity. In addition, the construction cost of these power generation facilities is very high. Therefore, mankind urgently needs to explore and apply 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 submersible piston cooperative drive engine and a power generation and control method. The submersible piston cooperative drive engine is a kind of energy that makes full use of stable, clean and permanently usable energy such as gravitational potential energy and buoyancy potential energy, and by effectively converting gravitational potential energy and buoyancy potential energy into cooperative driving force, it creates an engine that outputs high-quality power stably, continuously and efficiently. Among them, the inventors invented the key core technology and equipment of the submersible piston. Realizing precise control of the operating cycle of the submersible piston is the key to the submersible piston cooperative drive engine to generate high-quality power. To this end, the inventors have invented a piston motion controller to achieve locking and release control of the submersible piston. At the same time, the inventors have invented a piston fixed angle control switch to achieve precise control of the operating cycle of the submersible piston.

[0003] Through scientific and technological literature retrieval and investigation and research, although some researchers are exploring and experimenting with methods and devices for generating power using gravity and buoyancy, these methods and devices are too simple and fail to effectively solve the technical problem of converting gravitational potential energy and buoyancy potential energy into a synergistic driving force, and do not solve 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 and abroad have conducted 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 fixed angle control switch 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 fixed angle control switch and a submersible piston fixed angle control method. The piston fixed angle control switch realizes precise control of the start of the submersible piston according to the set start angle, ensuring that the submersible piston has an accurate cyclic motion period, so that the cyclic motion of the submersible piston has good stability, reliability and continuity.

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

[0006] A piston fixed angle control switch is used in a submersible piston cooperative drive engine and is linked with a piston motion controller. Two piston fixed angle control switches and two piston motion controllers are installed in the piston cylinder of each submersible piston cooperative drive engine. A piston fixed angle control switch and a piston motion controller form a group and are fixed on the same base on the inner wall of the two ends of the piston cylinder. The base is fixed on the two ends of the piston cylinder and the end support mechanism. The piston fixed angle control switch includes a circulation pipeline, a gravity ball, a gravity ball starting platform, a circulation pipeline support column, a gravity drive arm, a gravity ball blocking plate, a gravity arm support column, a transmission arm, a transmission arm support column, a starting arm, a starting arm support column, a connecting shaft, a supporting shaft, a stable control spring and a base, wherein:

[0007] The circulation pipeline is an annular tubular structure that carries and controls the gravity ball to make a unidirectional circulation movement, and controls the gravity ball to collide with the gravity drive arm according to the set submerged piston starting angle, including a circulation pipe body, a baffle bridge, a gravity ball starting platform, a gravity drive arm opening and a circulation pipe support column. The circulation pipe body is equipped with a gravity ball starting platform and a pipe section with a gravity drive arm opening as the main pipe body, and the other pipe section is the auxiliary pipe body. The main pipe body and the auxiliary pipe body constitute a complete and continuous circulation pipe body. The pipe wall close to the geometric center of the circulation pipe body is the inner pipe wall, and the pipe arm located outside the inner pipe wall is the outer pipe wall. The circulation pipe body is supported by the circulation pipe. The support column is fastened and supported, and the circulation pipeline support column is installed and fixed on the base, and the base is installed and fixed on the ends of the piston cylinder of the submerged piston cooperative driving engine and the end support mechanism; the present invention has created two circulation pipelines, namely the baffle bridge type circulation pipeline and the gravity driven circulation pipeline, and a piston fixed angle control switch can select one of the two circulation pipelines; the baffle bridge is installed in the baffle bridge type circulation pipeline, and is used to control the gravity ball to do unidirectional circulation movement. The present invention has created two baffle bridges, namely the gear controlled baffle bridge and the impact-pressure baffle bridge, and one baffle bridge can select one of the two baffle bridges;

[0008] The gravity ball is a spherical component that performs unidirectional circulation movement in the circulation tube body, and uses the angle between the piston cylinder of the engine and the vertical line of the engine center axis to be the starting angle according to the set submerged piston cooperative driving engine, and uses its own gravity and the impact force of free fall to collide with the gravity driving arm, and the gravity driving arm drives the piston motion controller to release the submerged piston through various transmission mechanisms connected thereto, so that the submerged piston starts to move;

[0009] The gravity ball starting platform is a circular arc groove straight platform mechanism that carries and controls the gravity ball to start falling and hit the end of the gravity drive arm according to the set submerged piston starting angle. When the piston cylinder rotates to the set submerged piston starting angle, the gravity ball starting platform is just in a horizontal state. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform and hits the end of the gravity drive arm.

[0010] The gravity driving arm is a rod-shaped mechanism that bears the impact of the gravity ball and uses the lever principle to pry the transmission mechanism connected thereto. One end of the gravity driving arm is located in the rectangular opening of the circulation tube body and bears the impact of the gravity ball. The other end is connected to the transmission arm through a connecting shaft. The middle part of the gravity driving arm is supported by a gravity arm support column. The gravity driving arm and the gravity arm support column are connected by a support shaft. The gravity arm support column is installed and fixed on the base. The support shaft includes a bearing, a bearing shaft and a bearing support seat. The inner ring of the bearing is fixed in series on the bearing shaft. Both ends of the bearing shaft are fixed on two bearing support seats. The bearing support seat is fixed on the end of the gravity arm support column. The gravity driving arm is fixed on the outer ring of the bearing and can rotate around the bearing.

[0011] The transmission arm is a rod-shaped mechanism that uses the lever principle to transmit driving force and change the direction of the driving force. One end of the transmission arm is connected to one end of the gravity driving arm through a connecting shaft, and the other end is connected to the starting arm through a connecting shaft. The middle part is supported by a transmission arm support column. The transmission arm and the transmission arm support column are connected by a support shaft. The transmission arm support column is installed and fixed on the base.

[0012] The starting arm is a rod-shaped mechanism that drives the piston movement controller of the submersible piston to cooperate with the driving engine to release the submersible piston and allow the submersible piston to start moving. One end of the starting arm is connected to one end of the transmission arm through a connecting shaft, and the other end is connected to the crank arm control ring of the piston movement controller. The middle part is supported by a starting arm support column. The starting arm and the starting arm support column are connected by a supporting shaft, and the starting arm support column is installed and fixed on the base; the various support columns can be connected and reinforced with cross bars to form a whole, so as to improve the supporting strength and stability of all supporting mechanisms; in the process of the piston cylinder of the submersible piston cooperatively driving the engine rotating, when the piston cylinder rotates to the set submersible position, the piston cylinder is connected to the submersible position. When the floating piston starts at an angle, the gravity ball on the gravity ball starting platform immediately starts to fall and hits the end of the gravity drive arm. The end of the gravity drive arm immediately starts to move downward, and the other end of the gravity drive arm starts to move upward, pulling the end of the transmission arm to move upward, and the other end of the transmission arm moves downward, and drives the end of the starting arm to move downward, so that the other end of the starting arm drives the crank arm control ring of the piston motion controller together with the crank arm sliding sleeve to move upward, and instantly drives the two clamping crank arm clamping ends of the piston motion controller to open outward, releasing the submerged floating piston, and the submerged floating piston moves rapidly to the other end of the piston cylinder under the initial thrust of the piston motion controller sleeve spring and the buoyancy of the liquid;

[0013] The connecting shaft is a connecting mechanism that can transmit driving force and allow the end of the driving arm to slide and rotate freely along the end of the force-bearing arm without separating from the force-bearing arm. The connecting shaft includes a linear bearing, a linear bearing sleeve rod, a sleeve rod column, a bearing and a bearing shaft rod. The linear bearing is sleeved on the end of the force-bearing arm so that the linear bearing can slide back and forth along the end of the force-bearing arm. The linear bearing sleeve rod is fixed on the outer ring of the linear bearing. The end of the linear bearing sleeve rod is made into two parallel sheet-like sleeve rod columns. Holes are opened on the two sleeve rod columns. The bearing is placed between the two sleeve rod columns and fixed to the inner ring of the bearing with a bearing shaft rod in series. The bearing shaft rod is fixed to the openings of the two sleeve rod columns in series. The curved arm end of the driving arm is connected and fixed to the outer ring of the bearing. When the driving arm end applies driving force to the force-bearing arm end, the driving arm end can slide and rotate on the force-bearing arm end.

[0014] The stable control spring is a spring having one end connected and fixed to a transmission arm or a gravity drive arm near the connecting shaft and the other end connected and fixed to two or more springs on a base. When the gravity ball does not collide with the gravity drive arm, the stable control spring always pulls the gravity drive arm extending into the rectangular opening of the circulation tube body to the upper part of the rectangular opening by stretching. On the one hand, the gravity drive arm, the transmission arm and the start arm are in a stable initial state. On the other hand, the crank arm control ring of the piston motion controller together with the crank arm sliding sleeve and the clamping crank arm are in a stable initial state through the control of the start arm. When the gravity ball collides with the gravity drive arm, the gravity drive arm smoothly drives each transmission mechanism to work, and the stable control spring does not affect the collision and downward movement of the gravity ball and the movement of each transmission mechanism. After the gravity ball collides with the gravity drive arm, the stable control spring pulls the gravity drive arm and all the transmission mechanisms connected thereto to return to the initial state, thereby ensuring the stability and reliability of the piston fixed angle control switch and each transmission mechanism of the piston motion controller.

[0015] Regarding the circulation pipeline, the present invention has created two types of circulation pipelines, namely, the baffle bridge type circulation pipeline and the gravity driven type circulation pipeline, wherein:

[0016] The baffle bridge type circulation pipeline is a circulation pipeline in which the baffle bridge controls the gravity ball to perform stable and accurate unidirectional circulation movement. The baffle bridge type circulation pipeline includes a circulation pipe body, a baffle bridge, a gravity ball starting platform and a circulation pipe support column. The plane of the circulation pipe body is parallel to the rotation plane of the piston cylinder of the engine driven by the submerged piston. The cross-sectional inner diameter of the circulation pipe body is larger than the diameter of the gravity ball. The cross-sectional shape and size of each pipe section of the entire circulation pipe body are different. The circulation pipe body is supported and fixed by two or more circulation pipe support columns, and the circulation pipe support columns are installed and fixed on the base. The pipe wall of the circulation pipe body supporting the rolling of the gravity ball is a semicircular arc pipe wall, and the curvature radius of the semicircular arc pipe wall is larger than the curvature radius of the gravity ball. Since the gravity ball is in the circulation The gravity ball moves in the liquid of the circulating tube body. Except for the semicircular tube wall supporting the rolling of the gravity ball and the tube section where the gravity ball starting platform is located, holes are opened on the other tube walls of the circulating tube body. When the gravity ball moves in the circulating tube body, the liquid in the circulating tube body can flow out from the tube wall holes, thereby reducing the liquid resistance of the gravity ball when it moves in the circulating tube body; when the piston cylinder of the engine driven by the submerged piston rotates clockwise, the gravity ball also circulates in the circulating tube body in the clockwise direction. When designing and manufacturing the circulating tube body, a rectangular hole must be cut in the middle of the left tube wall of the main tube body, and one end of the gravity drive arm is placed in the rectangular hole. The end of the gravity drive arm can move up and down in the rectangular hole; the baffle bridge is to control the gravity The force ball performs unidirectional circulation motion in the circulation pipe body, and acts as a bridge for the gravity ball, allowing the gravity ball to roll from the outer tube wall of the circulation pipe body to the inner tube wall of the circulation pipe body. The baffle bridge type circulation pipe has two baffle bridges, which are respectively installed on the upper and lower parts of the circulation pipe body; when the submerged piston cooperates to drive the piston cylinder of the engine to rotate in the vertical plane, the baffle bridge type circulation pipe also rotates in the vertical plane. When the piston cylinder rotates to the right side of the horizontal plane below the center axis of the engine, the gravity ball has run to and stopped on the gravity ball starting platform. When the piston cylinder rotates to the submerged piston starting angle, the gravity ball starting platform just rotates to a horizontal state. As the piston cylinder rotates further, the gravity ball immediately begins to fall from the gravity ball starting platform under the action of its own gravity, and hits the gravity ball. At the end of the driving arm, the other end of the gravity driving arm drives each transmission mechanism, so that the piston motion controller releases the submerged piston and allows the submerged piston to start moving. At this time, as the gravity driving arm in the circulation tube body tilts downward, the gravity ball continues to roll rapidly downward along the circulation tube body; when the piston cylinder of the submerged piston cooperatively drives the engine to rotate in the counterclockwise direction, the installation method of the baffle bridge type circulation pipeline is a mirror image installation method of the baffle bridge type circulation pipeline rotating in the clockwise direction; the baffle bridge type circulation pipeline is suitable for submerged piston cooperatively driven engines in all working environments, especially for engines and mobile engines in vibration and tilt environments, the baffle bridge type circulation pipeline can ensure the stability and accuracy of the gravity ball controlling the start of the submerged piston;

[0017] The gravity-driven circulation pipeline is a circulation pipeline that allows the gravity ball to stably and accurately perform unidirectional circulation movement under the driving force of the gravity ball's own gravity, by constructing a circulation pipe body shape that is adapted to the unidirectional circulation movement of the gravity ball, constructing a pipe wall shape for the rolling of the gravity ball, and controlling a gravity ball stabilizer. The gravity-driven circulation pipeline includes a circulation pipe body, a gravity ball starting platform, a gravity ball stabilizer, and a circulation pipe support column; the circulation pipe body refers to a circulation pipe body that adapts to the gravity ball to perform unidirectional circulation movement along the circulation pipe body in the opposite direction to the rotation of the piston cylinder under the driving force of its own gravity during the rotation of the piston cylinder. The main pipe body of the circulation pipe body is a straight pipe, and the auxiliary pipe body is an arc pipe. The main pipe body and the auxiliary pipe body of the circulation pipe body can be on the same The main body and the auxiliary body are in the same plane, or they may not be in the same plane. The circulation pipe body plane of the main body and the auxiliary body in the same plane is parallel to the rotation plane of the piston cylinder. The main body and the auxiliary body in not the same plane are staggered, so that the tube wall slope of the entire auxiliary body becomes gentle during the rotation of the piston cylinder, thereby slowing down the movement speed of the gravity ball in the circulation pipe body, ensuring the stability of the gravity ball movement. The cross-sectional inner diameter of the circulation pipe body is larger than the diameter of the gravity ball. The cross-sectional shape and size of each pipe section of the entire circulation pipe body are different. The circulation pipe body is supported and fixed by two or more circulation pipe support columns, and the circulation pipe support columns are installed and fixed on the base; the tube wall section of the circulation pipe body supporting the rolling of the gravity ball is The semicircular tube wall has a curvature radius greater than that of the gravity ball. Since the gravity ball moves in the liquid of the circulation tube body, holes are opened on other tube walls of the circulation tube body except for the semicircular tube wall supporting the rolling of the gravity ball and the tube section where the gravity ball starting platform is located. When the gravity ball moves in the circulation tube body, the liquid in the circulation tube body can flow out from the tube wall holes, thereby reducing the liquid resistance of the gravity ball when it moves in the circulation tube body. When the piston cylinder of the engine driven by the submerged piston rotates in the clockwise direction, the gravity ball circulates in the counterclockwise direction in the circulation tube body. At this time, the auxiliary tube body of the circulation tube body is located on the right side of the main tube body. When the circulation tube body is designed and manufactured, it must be located on the main tube body. A rectangular opening is cut in the middle of the left tube wall, and one end of the gravity driving arm is placed in the rectangular opening, and the one end of the gravity driving arm can move up and down in the rectangular opening; a plurality of gravity ball stabilizers are installed in the circulation tube body, and the gravity ball stabilizer is a stabilizing mechanism that can flexibly rotate in the direction of movement of the gravity ball, and is installed on the inner wall of the upper part of the circulation tube body and is located above the gravity ball. When the gravity ball passes through the gravity ball stabilizer, the gravity ball stabilizer will control the movement speed of the gravity ball to prevent the gravity ball from moving too fast under the action of its inertia. When the gravity ball moves to the gravity ball starting platform, the gravity ball stabilizer controls the gravity ball to start falling from the gravity ball starting platform only when the gravity ball starting platform rotates to a horizontal plane;When the piston cylinder rotates clockwise in the vertical plane, the gravity-driven circulation pipeline also rotates clockwise in the vertical plane. When the piston cylinder rotates to below the horizontal plane on the right side of the engine center axis, the gravity ball has run to and stopped on the gravity ball starting platform. When the piston cylinder rotates to the submerged piston starting angle, the gravity ball starting platform just rotates to a horizontal state. As the piston cylinder rotates further, the gravity ball immediately begins to fall from the gravity ball starting platform under the action of its own gravity, and hits the end of the gravity drive arm. The other end of the gravity drive arm drives each transmission mechanism, so that the piston motion controller releases the submerged piston and allows the submerged piston to start moving. At this time, as the gravity drive arm in the circulation pipe body tilts downward, the gravity ball continues to roll rapidly downward along the circulation pipe body. When the gravity ball rolls to the bottom of the circulation pipe body, as the piston cylinder continues to rotate, the gravity ball moves along the right side of the circulation pipe body. The auxiliary pipe body continues to move counterclockwise. When the piston cylinder rotates again to the right side of the engine central axis, the gravity ball moves to and stops on the gravity ball starting platform again. In this way, the gravity ball drives the piston motion controller to release the submerged piston stably and accurately through the gravity drive arm and the transmission mechanism connected thereto, so that the submerged piston can perform stable and accurate reciprocating motion. When the submerged piston cooperates with the piston cylinder of the engine to rotate counterclockwise, the installation method of the gravity-driven circulation pipeline is a mirror image installation method of the gravity-driven circulation pipeline rotating clockwise. The gravity-driven circulation pipeline is more suitable for engines in a static environment. For engines installed and fixed in a machine room, the gravity-driven circulation pipeline can ensure the stability and accuracy of the gravity ball controlling the submerged piston to start, and the production, installation and maintenance are simple and convenient. ;

[0018] The baffle bridge is a control mechanism installed in the baffle bridge type circulation pipeline and controls the gravity ball to make a one-way circulation movement. The present invention has created two types of baffle bridges, namely, a gear-controlled baffle bridge and a collision-type baffle bridge, wherein:

[0019] The gear-controlled baffle bridge includes a baffle, a baffle gear, a gear shaft, a bearing, a transmission rack, a rack connecting plate, a connecting plate shaft, a connecting plate supporting spring and a baffle support frame. Two gear-controlled baffle bridges are installed in the circulation tube body, namely, a goal baffle bridge and a return baffle bridge. The baffle bridge close to the gravity ball starting platform and allowing the gravity ball to move to the gravity ball starting platform through the baffle bridge is the goal baffle bridge, and the baffle bridge installed at the lower part of the circulation tube body and allowing the gravity ball to move toward the goal baffle bridge is the return baffle bridge; the baffle bridge on both sides of the baffle The supporting rod at the lower end is symmetrically connected and fixed on the chord of the two baffle gears. The centers of the two baffle gears are respectively installed with gear shafts. The gear shafts are respectively connected and fixed on the two inner rings of the bearings. The two outer rings of the bearings are respectively connected and fixed on the lower part of the inner wall of the circulation tube body. The connecting line between the centers of the two baffle gears is horizontal. The two baffle gears are meshed with the two transmission racks. The two transmission racks are installed and fixed on the ends of the connecting rods on both sides of the rack connecting plate. The two sides of the rack connecting plate are supported by the connecting plate shafts. The shafts are connected and fixed on the two inner rings of the bearings respectively, and the two outer rings of the bearings are connected and fixed on the lower part of the inner wall of the circulation tube body respectively; two or more connecting plate support springs are installed at the lower part of the other end of the rack connecting plate, and the elastic force of all the connecting plate support springs is less than the gravity of the gravity ball. When the gravity ball does not pass through the baffle bridge, the supporting elastic force of the connecting plate support springs makes the rack connecting plate and the baffle always overlap. When the gravity ball passes through the baffle bridge, the rack connecting plate and the baffle are in an overlapped state, so that the gravity ball can smoothly pass through the groove. When the gravity ball passes over the baffle and rolls on the rack connecting plate, under the gravity of the gravity ball, one end of the rack connecting plate moves downward and compresses the connecting plate support spring, and at the same time pries the transmission rack at the other end to move upward, the transmission rack drives the baffle gear to rotate, and the baffle gear drives the baffle to stand up and close to the baffle support frame, sealing the pipe opening to prevent the gravity ball from rolling back into the main pipe body. When the gravity ball leaves the baffle bridge, under the support of the connecting plate support spring, the rack connecting plate and the baffle return to the overlapping state;As the circulating pipe body rotates with the piston cylinder, when the gravity ball starting platform rotates to a horizontal state, the gravity ball begins to fall, and after hitting the gravity driving arm, it moves toward the direction of the ball return baffle bridge. When the gravity ball passes over the baffle of the ball return baffle bridge and rolls on the rack connecting plate, the gravity ball pushes one end of the rack connecting plate to move downward, and the baffle of the ball return baffle bridge immediately stands up and seals the pipe opening. As the circulating pipe body continues to rotate, the gravity ball uses the grooved baffle as a bridge to roll from the outer pipe wall of the circulating pipe body to the inner pipe wall. As the circulating pipe body continues to rotate, the gravity ball continues to The gravity ball continues to move in the auxiliary pipe body and passes over the baffle of the goal baffle bridge and rolls on the rack connecting plate of the goal baffle bridge. At this time, the gravity ball pushes the rack connecting plate downward, and the baffle of the goal baffle bridge immediately stands up and presses against the baffle support frame to close the pipe opening. As the circulation pipe body continues to rotate, the gravity ball rolls back to the grooved baffle and uses the grooved baffle as a bridge to roll to the gravity ball starting platform. At this time, a V-shaped groove body with an opening upward is formed between the grooved baffle and the gravity ball starting platform. The gravity ball stops at the bottom of the V-shaped groove body and continues to rotate with the circulation pipe body. , the gravity ball starting platform rotates to a horizontal state, the gravity ball begins to fall, and after hitting the gravity driving arm, it moves toward the direction of the ball return baffle bridge; the baffle is a grooved grid plate with straight sides, which can allow the gravity ball to move stably on the straight arc grooves on both sides of the baffle, that is, the baffle is formed by orthogonally connecting and fixing a plurality of grooved straight plates with grooves on both sides and a plurality of arc-shaped plates with arcs on both sides, forming a grooved grid plate with grooves on both sides, the width of the middle grooved straight plate is greater than the width of each grooved straight plate on both sides, and the rack connecting plate is composed of a plurality of grooves A grooved grid plate is formed by orthogonally connecting and fixing a plurality of arc-shaped plates, and the width of the grooved straight plate in the middle is greater than the width of each grooved straight plate on both sides, so that the gravity ball can roll stably on the grooved baffle plate and the grooved rack connecting plate. The construction of the grid-shaped baffle plate and the grid-shaped rack connecting plate can reduce the liquid resistance when the baffle plate and the rack connecting plate rotate, and the cross-sectional curvature radius of the baffle plate and the rack connecting plate is greater than the curvature radius of the gravity ball; the gear-controlled baffle bridge is more suitable for a high-power submerged piston cooperative drive engine with a heavy gravity ball;

[0020] The impact-type baffle bridge comprises an impact baffle, an impact baffle rotating shaft, a bearing, a torsion spring and a baffle support frame. Two impact-type baffle bridges are installed in the circulation tube body, namely, a goal baffle bridge and a return ball baffle bridge. The baffle bridge close to the gravity ball starting platform and allowing the gravity ball to move to the gravity ball starting platform through the baffle bridge is the goal baffle bridge, and the baffle bridge installed at the lower part of the circulation tube body and allowing the gravity ball to move toward the goal baffle bridge is the return ball baffle bridge; the impact baffle is a straight grooved grid plate made of light hard wear-resistant material, the curvature radius of the cross section of the impact baffle is greater than the curvature radius of the gravity ball, one end of the impact baffle is connected and fixed on the impact baffle rotating shaft, and a miniature torsion spring is connected in series at each end of the impact baffle rotating shaft, and one end of the torsion spring is connected The cam is fixed on the impact baffle, and the other end is connected and fixed on the inner wall of the circulation pipe body. The torsion spring can assist the impact baffle to close the pipe opening. The ends of the impact baffle rotating shaft are connected and fixed on the two inner rings of the bearings in series. The two outer rings of the bearings are installed and fixed on the inner wall of the pipe wall of the circulation pipe body. The impact baffle can rotate around the impact baffle rotating shaft and the bearings. In the process of the circulation pipe body rotating with the piston cylinder, when the gravity ball starting platform rotates to a horizontal state, the gravity ball starts to fall from the gravity ball starting platform, and moves to the lower part of the main body of the circulation pipe body after hitting the gravity driving arm, and rolls to the bottom of the main body after hitting the impact baffle of the return ball baffle bridge. At this time, as the circulation pipe body continues to rotate, the main body gradually tends to a horizontal state. In this process, the return ball baffle bridge The impact baffle of the ball baffle bridge rotates to the baffle support frame in advance under the action of its own gravity and the elastic force of the torsion spring to close the pipe mouth, and the gravity ball begins to roll back to the impact baffle, and uses the groove-shaped impact baffle as a bridge to roll from the outer tube wall of the circulation tube body to the inner tube wall. As the circulation tube body continues to rotate, the gravity ball quickly moves along the auxiliary tube body to the goal baffle bridge, and hits the impact baffle of the goal baffle bridge and then moves to the bottom of the auxiliary tube body. As the circulation tube body continues to rotate, the impact baffle of the goal baffle bridge rotates to the baffle support frame in advance under the action of its own gravity and the elastic force of the torsion spring to close the pipe mouth, and the gravity ball begins to roll back to the impact baffle, and uses the groove-shaped impact baffle as a bridge to roll from the outer tube wall of the circulation tube body to the gravity ball starting platform. When the collision baffle rotates in the liquid of the circulation tube body, the collision baffle needs to be made into a water-permeable mesh plate to reduce the liquid resistance when the collision baffle rotates. The collision baffle is formed by orthogonally connecting and fixing a plurality of grooved straight plates and a plurality of arc-shaped rods to form a semicircular grooved mesh plate. The width of the grooved straight plate in the middle is greater than the width of each grooved straight plate on both sides, so that the gravity ball can roll stably on the grooved straight plate. The collision baffle is made of high-strength, lightweight and wear-resistant material.The impact-type baffle bridge is more suitable for the small-power submersible piston cooperative drive engine of the light-weight gravity ball, and is simple and convenient to produce, install and maintain. ;

[0021] The gravity-driven arm is a zigzag rod-shaped mechanism with one end located in the rectangular opening of the circulation pipe body and the other end connected to the end of the transmission arm, and the middle part is supported by the gravity arm support column. The gravity-driven arm has two construction and support methods, namely, the gravity-driven arm construction and support method based on the baffle bridge circulation pipeline and the gravity-driven arm construction and support method based on the gravity-driven circulation pipeline, wherein:

[0022] The gravity drive arm construction and support method based on the baffle bridge type circulation pipeline is as follows: since the auxiliary pipe body of the circulation pipe body is located on the left side of the main pipe body with the rectangular opening, and the other end of the gravity drive arm is also located on the left side of the main pipe body with the rectangular opening, when both are located on the left side of the main pipe body, the gravity drive arm leaving the rectangular opening is separated into two drive arms and made into an annular gravity drive arm, and the auxiliary pipe body on the left side is sleeved inside the annular gravity drive arm so that the gravity drive arm can make up and down tilting movements, and the other end of the gravity drive arm is combined to form a drive arm, and the end connected to the transmission arm is made into a short rod perpendicular to the gravity drive arm, and the gravity drive arm is supported by a gravity arm support column, which can be installed inside or outside the circulation pipe body. The two support methods make the arm lengths of the gravity drive arms on both sides of the fulcrum of the gravity arm support column different, and the specific support point selection needs to be calculated and determined according to the arm length requirements of the gravity drive arms on both sides of the support point;

[0023] The gravity-driven arm construction and support method based on the gravity-driven circulation pipeline is as follows: the auxiliary tube body of the circulation tube body is located on the right side of the main tube body with a rectangular opening, and the other end of the gravity-driven arm is located on the left side of the main tube body with a rectangular opening, and the two are in opposite directions. Therefore, the gravity-driven arm is a straight, complete rod-shaped mechanism, and the end connected to the transmission arm is made into a short rod perpendicular to the gravity-driven arm. The middle part of the gravity-driven arm is supported by the gravity arm support column, and the specific support point selection needs to be calculated and determined based on the arm length requirements of the gravity-driven arm on both sides of the support point.

[0024] The end rod section of the gravity driving arm located in the rectangular opening of the circulation tube body is evenly provided with a plurality of small holes. Since the gravity driving arm rotates in the liquid of the circulation tube body, when the gravity ball hits the end of the gravity driving arm, the gravity driving arm quickly tilts downward. At this time, the liquid in the circulation tube body flows out from all the small holes. On the one hand, the resistance of the liquid to the downward tilting movement of the gravity driving arm is reduced. On the other hand, the liquid emerging from the small holes directly pushes the gravity ball to leave the gravity driving arm, thereby accelerating the falling speed of the gravity ball. At the same time, a gravity ball blocking plate is fixedly installed on the gravity driving arm located in the rectangular opening of the circulation tube body. The gravity ball blocking plate is close to the inner side of the rectangular opening of the circulation tube body to prevent the gravity ball from accidentally leaving the circulation tube body. The gravity ball blocking plate is an arc-shaped sheet straight plate. The curvature radius and arc direction of the gravity ball blocking plate are the same as the curvature radius and arc direction of the tube wall inside the circulation tube body.

[0025] The gravity ball starting platform is a groove-shaped straight platform mechanism that controls the gravity ball to start falling and collide with the end of the gravity driving arm according to the set submerged piston starting angle. The gravity ball starting platform is close to the goal baffle bridge, and its surface is designed and manufactured into an arc-shaped groove-shaped straight surface. The lines connecting the two sides of the gravity ball starting platform perpendicular to the upper edge of the arc groove are in a horizontal state, and the curvature radius of the arc groove is variable. The curvature radius of the arc groove close to the goal baffle bridge is close to the curvature radius of the gravity ball, thereby increasing the contact area between the gravity ball and the arc groove, and the curvature radius of the arc groove in the direction of the gravity ball rolling down gradually increases, thereby reducing the contact area between the gravity ball and the arc groove, thereby ensuring the stability of the gravity ball when it stops on the gravity ball starting platform, and ensuring that the gravity ball can fall quickly. At the same time, high-strength and wear-resistant anti-vibration and anti-skid materials are laid on the gravity ball starting platform to ensure the stability and accuracy of the gravity ball rolling on the platform; the starting position of the gravity ball is based on the position of the set submerged floating piston starting angle, that is, the starting angle of the submerged floating piston is the angle between the piston cylinder of the submerged floating piston cooperative driving engine and the vertical line of the engine center axis as the starting angle. When the piston cylinder rotates to the set starting angle, the gravity ball starting platform is just in a horizontal state. When the piston cylinder rotates further, the gravity ball immediately starts to fall and hits the gravity drive arm. The other end of the gravity drive arm drives the transmission mechanism connected thereto to control the piston motion controller to release the submerged floating piston, so that the submerged floating piston starts to move.

[0026] A method for controlling a submersible piston at a fixed angle is disclosed. The fixed angle control of the submersible piston is to periodically collide with a gravity drive arm according to a set starting angle and starting position of the submersible piston by a gravity ball. The gravity drive arm drives a piston motion controller to release the submersible piston through a transmission mechanism connected thereto, so that the submersible piston starts to move, thereby realizing periodic reciprocating motion of the submersible piston, and achieving the purpose of controlling the speed of the submersible piston to coordinately drive the engine. The specific control method is as follows:

[0027] (1) Calculate and determine the number and weight of the submersible pistons. The speed and power of the submersible piston cooperative drive engine are determined by the number, length, shape, capacity of the piston cylinders, the height and weight of the liquid in the piston cylinders and the gravity box, and the volume and weight of the submersible pistons. After the design speed and design power of the submersible piston cooperative drive engine are determined, first calculate and determine the number, length, shape, capacity of the piston cylinders, and the height and weight of the liquid in the piston cylinders and the gravity box. Then, the number and weight of the submersible pistons can be calculated and determined;

[0028] (2) Design and establish that the buoyancy of the submersible piston immersed in the liquid is greater than its own weight. When designing and manufacturing the submersible piston, by calculating the volume, buoyancy, and gravity of the submersible piston and all other mechanisms and components, the buoyancy of the submersible piston in the liquid is designed to be greater than its own weight, so that the submersible piston always has the ability to float in the liquid in the piston cylinder;

[0029] (3) Calculate and determine the effective length and one-way motion time of the submerged piston in the piston barrel. Based on the length of the piston barrel and the distance from the piston control top of the piston motion controller installed at both ends of the piston barrel to the inner wall of the piston barrel end, the effective length of the submerged piston in the piston barrel can be calculated and determined. Based on the buoyancy calculation formula and the physical kinematics formula, the one-way motion time of the submerged piston in the piston barrel when the piston barrel is perpendicular to the horizontal plane or at other angles to the horizontal plane can be calculated and determined, providing a basis for determining the starting angle when the submerged piston starts to move. The one-way motion time of the submerged piston in the piston barrel determines the speed of the engine. If the one-way motion time of the submerged piston in the piston barrel cannot meet the design speed requirement of the engine, it is necessary to recalculate and adjust the volume of the submerged piston, that is, change the liquid buoyancy of the submerged piston until the design speed requirement of the engine is met;

[0030] (4) Calculate the starting angle for the submersible piston to start moving. After calculating and determining the one-way movement time of the submersible piston in the piston cylinder, the rotation angle of the piston cylinder during the one-way movement time of the submersible piston can be calculated based on the speed of the engine driven by the submersible piston. The principle is to maximize the torque difference between the submersible piston on the left and right sides of the vertical line of the engine center axis, and the angle between the piston cylinder and the vertical line of the engine center axis is used as the starting angle when the submersible piston starts moving. The position of the piston cylinder in the vertical rotation plane is determined, and the position of the piston cylinder is used as the starting position for the submersible piston to start moving.

[0031] (5) Setting the horizontal position of the gravity ball starting platform. The horizontal position of the gravity ball starting platform is the position corresponding to the set starting angle of the submerged floating piston when the piston cylinder rotates. That is, when the piston cylinder rotates to the position corresponding to the starting angle of the submerged floating piston, the gravity ball starting platform is just in a horizontal state. As the piston cylinder rotates further, the gravity ball immediately begins to fall from the gravity ball starting platform and hits the gravity drive arm. The gravity drive arm drives the clamping ends of the two clamping crank arms of the piston motion controller through the transmission mechanism connected thereto to release the submerged floating piston, allowing the submerged floating piston to start floating upward.

[0032] (6) Calculate and determine the arm lengths of the gravity drive arm, transmission arm, and start arm, and the movement distance of the crank arm control ring. The gravity drive arm is connected to the transmission arm and the start arm, and the middle of each transmission mechanism is supported by a support column. The start arm is connected to the crank arm control ring of the piston motion controller, and drives the crank arm control ring together with the crank arm sliding sleeve to move in the direction of the submerged piston, drives the clamping end of the clamping crank arm to release the submerged piston, and allows the submerged piston to start moving. This requires the calculation and determination of the arm lengths at both ends of each support point of the gravity drive arm, transmission arm, and start arm, as well as the distance that the crank arm control ring and the crank arm sliding sleeve need to drive the clamping end of the clamping crank arm to release the submerged piston, based on the principles of accuracy, efficiency, and effort saving, so that the driving force can be effectively transmitted and driven between the gravity drive arm and the transmission mechanism connected thereto;

[0033] (7) Calculate and determine the weight of the gravity ball. The gravity of the gravity ball is used to drive the gravity drive arm and the transmission mechanism connected thereto, and overcome the elastic tension of the stabilizing control spring and the crank arm spring of the piston motion controller. After determining the arm length and movement distance of the gravity drive arm and the transmission mechanism connected thereto, as well as the elastic tension of the stabilizing control spring and the crank arm spring, the weight of the gravity ball can be calculated and determined, allowing the gravity ball to successfully complete the driving task;

[0034] (8) Automatically control the start-up and unidirectional circulation of the gravity ball. The gravity ball is a spherical component that performs unidirectional circulation in the circulation pipe body and collides with the gravity drive arm. The piston fixed angle control switch can adopt a baffle bridge type circulation pipe or a gravity drive type circulation pipe. When the baffle bridge type circulation pipe is adopted, when the piston cylinder rotates to the position corresponding to the starting angle of the submerged piston, the gravity ball starting platform is just in a horizontal state, and the gravity ball is located on the gravity ball starting platform. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform, and after colliding with the gravity drive arm, it continues to move to the bottom of the circulation pipe body and passes over the baffle of the ball return baffle bridge. At this time, the baffle is erected and closes the pipe. The piston cylinder continues to rotate, and the gravity ball begins to roll back and enters the auxiliary pipe body of the circulation pipe body through the grooved baffle plate. As the piston cylinder continues to rotate, the gravity ball moves toward the goal baffle plate bridge and crosses the baffle plate of the goal baffle plate bridge. At this time, the baffle plate stands up and closes the pipe opening. As the piston cylinder continues to rotate, the gravity ball begins to roll back and moves to the bottom of the groove between the grooved baffle plate of the goal baffle plate bridge and the gravity ball starting platform. When the piston cylinder rotates to the position corresponding to the starting angle of the submerged piston, the gravity ball immediately begins to fall from the gravity ball starting platform and hits the gravity drive arm. Under the control of the baffle bridge type circulation pipeline, the gravity ball always It is able to stably and accurately perform unidirectional circulation movement, and according to the set submersible piston starting angle, it collides with the gravity drive arm to control the periodic circulation movement of the submersible piston; when a gravity-driven circulation pipeline is adopted, when the piston cylinder rotates to the position corresponding to the submersible piston starting angle, the gravity ball starting platform is just in a horizontal state, and the gravity ball is located on the gravity ball starting platform. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform, and continues to move toward the bottom of the circulation pipe body after colliding with the gravity drive arm. As the piston cylinder continues to rotate, the gravity ball reaches the bottom of the circulation pipe body and begins to enter the auxiliary pipe on the other side. As the piston cylinder continuously rotates, the gravity ball moves along the auxiliary tube body and moves again to the bottom of the groove at the joint of the groove-shaped auxiliary tube body and the gravity ball starting platform. The gravity ball stabilizer controls and stabilizes the movement speed of the gravity ball from beginning to end. When the piston cylinder rotates to the position corresponding to the submerged piston starting angle, the gravity ball immediately starts to fall from the gravity ball starting platform and hits the gravity drive arm. Under the control of the gravity-driven circulation pipeline, the gravity ball can always stably and accurately perform unidirectional circulation movement, and hit the gravity drive arm according to the set submerged piston starting angle, so as to control the periodic circulation movement of the submerged piston.

[0035] (9) Automatically control the submersible piston to reciprocate periodically. The piston fixed angle control switch and the piston motion controller are respectively installed on the inner wall at both ends of the piston cylinder. When the submersible piston cooperates with the rotating disk of the engine to rotate clockwise, when the piston cylinder rotates to the position corresponding to the submersible piston starting angle below the horizontal plane on the right side of the engine center axis, the gravity ball starting platform of the piston fixed angle control switch located at the outer end of the piston cylinder is just in a horizontal state, and the gravity ball is located on the gravity ball starting platform. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform and hits the gravity drive arm. The gravity drive arm drives the transmission mechanism connected to it to control the piston motion controller to release the submersible piston located at the outer end of the piston cylinder, and the submersible piston floats upward quickly. When the submersible piston moves to the locking position of the piston motion controller at the inner end of the piston cylinder, the piston motion controller immediately automatically locks the submersible piston, causing the submersible piston to stop moving. As the piston cylinder continues to rotate, when the piston cylinder rotates to the position corresponding to the submersible piston starting angle above the horizontal plane on the left side of the engine center axis, the piston at the inner end of the piston cylinder is locked. The gravity ball starting platform of the piston fixed angle control switch is just in a horizontal state, and the gravity ball is located on the gravity ball starting platform. As the piston cylinder rotates further, the gravity ball immediately begins to fall from the gravity ball starting platform and hits the gravity drive arm. The gravity drive arm drives the transmission mechanism connected thereto to control the piston motion controller to release the submerged floating piston located at the inner end of the piston cylinder, and the submerged floating piston quickly floats upward. When the submerged floating piston moves to the locking position of the piston motion controller at the outer end of the piston cylinder, the piston motion controller immediately automatically locks the submerged floating piston, so that the submerged floating piston stops moving. 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. The submerged floating pistons in all piston cylinders perform cyclic reciprocating motion in their respective piston cylinders in turn, so that the submerged floating pistons on the left and right sides of the vertical line of the engine central axis produce torque difference and torque difference, thereby driving the piston cylinder together with the engine rotating disk and the engine central axis to rotate and output power to the outside. When the submersible piston cooperates to drive the rotating disk of the engine to rotate counterclockwise, the control method of the periodic reciprocating motion of the submersible piston is the same as the control method when the rotating disk of the engine rotates clockwise.

[0036] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0037] (1) The present invention creates a submersible piston fixed angle control method, which uses the angle between the piston barrel of the submersible piston cooperatively driving the engine and the vertical line of the engine center axis as the starting angle for the submersible piston to start moving, and the position corresponding to the submersible piston starting angle as the starting position of the submersible piston. When the piston barrel rotates to the submersible piston starting position, the piston fixed angle control switch controls the piston motion controller to release the submersible piston, allowing the submersible piston to start moving. On the one hand, this control method greatly improves the stability, accuracy and reliability of the submersible piston motion control; on the other hand, by controlling the change of the submersible piston starting angle, the cyclic reciprocating motion period of the submersible piston can be regulated, thereby adjusting the speed of the submersible piston cooperatively driving the engine, which greatly improves the flexibility and adaptability of the submersible piston cooperatively driving the engine.

[0038] (2) The present invention creates a method for automatically controlling the start of a submersible piston by using a gravity ball. The start of the submersible piston is controlled by the unidirectional circular motion of the gravity ball and the collision with the gravity drive arm according to a set start angle, thereby realizing the automation of the start of the submersible piston and ensuring the stability and accuracy of the start of the submersible piston.

[0039] (3) The present invention creates a baffle bridge type circulation pipeline and a gravity driven circulation pipeline. The baffle bridge type circulation pipeline is suitable for submersible piston cooperatively driven engines in all working environments, especially for engines in vibration and tilting environments and mobile engines. The baffle bridge type circulation pipeline can ensure the stability and accuracy of the gravity ball controlling the start of the submersible piston; the gravity driven circulation pipeline is more suitable for engines in a static environment. For engines installed and fixed in a machine room, the gravity driven circulation pipeline can ensure the stability and accuracy of the gravity ball controlling the start of the submersible piston, and it is simple and convenient to produce, install and maintain. Therefore, the creation of the baffle bridge type circulation pipeline and the gravity driven circulation pipeline greatly improves the ability of the submersible piston cooperatively driven engine to adapt to various working environments.

[0040] (4) The present invention creates a gear-controlled baffle bridge and a collision-type baffle bridge. The gear-controlled baffle bridge is more suitable for a high-power submersible piston cooperatively driven engine with a heavy gravity ball, and the collision-type baffle bridge is more suitable for a low-power submersible piston cooperatively driven engine with a light gravity ball, and is simple and convenient to produce, install and maintain. The creation of the gear-controlled baffle bridge and the collision-type baffle bridge well meets the needs of submersible piston cooperatively driven engines of different powers.

[0041] (5) The present invention creates a method for controlling the stability of each transmission mechanism of a piston fixed angle control switch and a piston motion controller by using a stabilizing control spring. The stabilizing control spring is connected and fixed between a transmission arm or a gravity drive arm and a base. When the gravity ball does not collide with the gravity drive arm, the stabilizing control spring always pulls the gravity drive arm extending into the rectangular opening of the circulation tube body to close to the upper part of the rectangular opening by stretching. On the one hand, the gravity drive arm, the transmission arm and the start arm are always in a stable initial state. On the other hand, the crank arm control ring of the piston motion controller together with the crank arm sliding sleeve and the clamping crank arm are in a stable initial state through the control of the start arm. When the gravity ball collides with the gravity drive arm, the gravity drive arm smoothly drives each transmission mechanism to work, and the stabilizing control spring does not affect the collision and downward movement of the gravity ball and the movement of each transmission mechanism. After the gravity ball collides with the gravity drive arm, the stabilizing control spring pulls the gravity drive arm and all the transmission mechanisms connected thereto to return to the initial state. This method well ensures the stability and reliability of each transmission mechanism of the piston fixed angle control switch and the piston motion controller.

[0042] (6) The piston fixed angle control switch created by the present invention is a purely mechanical control system. The real-time linkage between the piston fixed angle control switch and the piston motion controller realizes the automation and precision of the submerged and floating 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 electrical 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.

[0058] See also Figure 1 and Figure 2 The gravity ball 3 performs unidirectional circulation in the circulation tube body 1, and the angle between the piston cylinder of the engine and the vertical line of the engine center axis is set as the starting angle, and uses its own gravity and the impact force of the free fall to hit the gravity drive arm 4. The gravity drive arm 4 drives the piston motion controller to release the submerged piston through various transmission mechanisms connected thereto, so that the submerged piston starts to move.

[0059] See also Figure 1 and Figure 2The gravity ball starting platform 15 is a circular arc groove straight platform mechanism that carries and controls the gravity ball 3 to start falling and hit the gravity drive arm 4 according to the set submerged piston starting angle. When the piston cylinder rotates to the set submerged piston starting angle, the gravity ball starting platform 15 is just in a horizontal state.

[0065] See also Figure 1 and Figure 7 Regarding the circulation pipeline, the present invention has created two types of circulation pipelines, namely, the baffle bridge type circulation pipeline and the gravity driven circulation pipeline, wherein:

[0066] See also Figure 1 , Figure 2 and Figure 6The baffle bridge type circulation pipeline is a circulation pipeline in which the baffle bridge 2 controls the gravity ball 3 to perform a stable and accurate unidirectional circulation movement. The baffle bridge type circulation pipeline includes a circulation pipe body 1, a baffle bridge 2, a gravity ball starting platform 15 and a circulation pipe support column 10. The plane of the circulation pipe body 1 is parallel to the rotation plane of the piston cylinder of the engine driven by the submerged piston. The inner diameter of the cross section of the circulation pipe body 1 is larger than the diameter of the gravity ball 3. The cross-sectional shape and size of each pipe section of the entire circulation pipe body 1 are different. The circulation pipe body 1 is supported and fixed by two or more circulation pipe support columns 10, and the circulation pipe support columns 10 are installed and fixed on the base 11; the pipe wall of the circulation pipe body 1 supporting the rolling of the gravity ball 3 is a semicircular arc pipe wall, and the semicircular arc The curvature radius of the semicircular tube wall is greater than the curvature radius of the gravity ball 3; since the gravity ball 3 moves in the liquid of the circulation tube body 1, in addition to the semicircular tube wall supporting the rolling of the gravity ball 3 and the tube section where the gravity ball starting platform 15 is located, there are openings on the other tube walls of the circulation tube body 1. When the gravity ball 3 moves in the circulation tube body 1, the liquid in the circulation tube body 1 can flow out from the tube wall openings, thereby reducing the liquid resistance of the gravity ball 3 when it moves in the circulation tube body 1; when the piston cylinder of the engine driven by the submerged piston rotates in the clockwise direction, the gravity ball 3 also circulates in the circulation tube body 1 in the clockwise direction. When designing and manufacturing the circulation tube body 1, a hole must be cut in the middle of the left tube wall of the main tube body. The rectangular hole is used to place one end of the gravity-driven arm 4 in the rectangular hole, and the end of the gravity-driven arm 4 can move up and down in the rectangular hole; the baffle bridge 2 is a control mechanism for controlling the gravity ball 3 to make a one-way circulation movement in the circulation pipe body 1, and serves as a bridge for the gravity ball 3, allowing the gravity ball 3 to roll from the outer wall of the circulation pipe body 1 to the inner wall of the circulation pipe body 1. The baffle bridge type circulation pipeline has two baffle bridges 2, which are respectively installed at the upper and lower parts of the circulation pipe body 1; when the submerged piston cooperates to drive the piston cylinder of the engine to rotate in the vertical plane, the baffle bridge type circulation pipeline also rotates in the vertical plane. When the piston cylinder rotates to below the horizontal plane on the right side of the engine center axis, the gravity ball 3 has run to and stopped on the gravity ball starting platform 15, and then the piston cylinder rotates to the right side of the engine center axis. When the piston cylinder rotates to the submerged piston starting angle, the gravity ball starting platform 15 just rotates to a horizontal state. As the piston cylinder rotates further, the gravity ball 3 immediately starts to fall from the gravity ball starting platform 15 under the action of its own gravity, and hits the end of the gravity drive arm 4. The other end of the gravity drive arm 4 drives each transmission mechanism, so that the piston motion controller releases the submerged piston and allows the submerged piston to start moving. At this time, as the gravity drive arm 4 in the circulation pipe body 1 tilts downward, the gravity ball 3 continues to roll rapidly downward along the circulation pipe body; when the piston cylinder of the submerged piston cooperates with the driving engine to rotate counterclockwise, the installation method of the baffle bridge type circulation pipeline is a mirror image installation method of the baffle bridge type circulation pipeline rotating in the clockwise direction;

[0067] See also Figure 7 and Figure 8The gravity-driven circulation pipeline is a circulation pipeline that is driven by the gravity ball's own gravity, and through the construction of the circulation pipe body 1 shape that adapts to the unidirectional circulation movement of the gravity ball 3, the construction of the pipeline wall shape for the rolling of the gravity ball 3, and the control of the gravity ball stabilizer 18, the gravity-driven circulation pipeline makes the gravity ball 3 stably and accurately perform unidirectional circulation movement. The gravity-driven circulation pipeline includes a circulation pipe body 1, a gravity ball starting platform 15, a gravity ball stabilizer 18, and a circulation pipe support column 10; the circulation pipe body 1 refers to a circulation pipe that adapts the gravity ball 3 to perform unidirectional circulation along the circulation pipe body 1 in the opposite direction of the rotation of the piston cylinder under the drive of its own gravity during the rotation of the piston cylinder. The main body of the circulation pipe body 1 is a straight pipe, and the auxiliary pipe body is an arc-shaped pipe. The main body and the auxiliary pipe body of the circulation pipe body 1 can be in the same plane or not. The plane of the circulation pipe body 1 in which the main body and the auxiliary pipe body are in the same plane is parallel to the rotation plane of the piston cylinder. The main body and the auxiliary pipe body in which they are not in the same plane are staggered, so that the wall slope of the entire auxiliary pipe body becomes gentle during the rotation of the piston cylinder, thereby slowing down the movement speed of the gravity ball 3 in the circulation pipe body 1, ensuring the stability of the movement of the gravity ball 3. The inner diameter of the circulation pipe body 1 is larger than the diameter of the gravity ball 3. The cross-sectional shape and size of each pipe section of the entire circulation pipe body 1 are different. The circulation pipe body 1 is supported and fixed by two or more circulation pipe support columns. The circulation pipe support column 10 is installed and fixed on the base 11; the pipe wall cross-section of the circulation pipe body 1 supporting the rolling of the gravity ball 3 is semicircular, and the curvature radius of the semicircular pipe wall is greater than the curvature radius of the gravity ball 3; because the gravity ball 3 moves in the liquid of the circulation pipe body, in addition to the semicircular pipe wall supporting the rolling of the gravity ball 3 and the pipe section where the gravity ball starting platform 15 is located, holes are opened on the other pipe walls of the circulation pipe body 1, and the gravity ball 3 moves in the circulation pipe body. When the circulation tube body 1 moves, the liquid in the circulation tube body 1 can flow out from the orifice of the tube wall, thereby reducing the liquid resistance of the gravity ball 3 when it moves in the circulation tube body 1; when the piston cylinder of the engine driven by the submerged piston rotates clockwise, the gravity ball 3 circulates in the circulation tube body 1 in the counterclockwise direction. At this time, the auxiliary tube body of the circulation tube body 1 is located on the right side of the main tube body. When the circulation tube body 1 is designed and manufactured, a rectangular orifice must be cut in the middle of the left tube wall of the main tube body, and one end of the gravity drive arm 4 is placed in the rectangular orifice. One end of the gravity drive arm 4 can move up and down in the rectangular orifice;Several gravity ball stabilizers 18 are installed in the circulation pipe body 1. The gravity ball stabilizer 18 is a stabilizing mechanism that can flexibly rotate in the direction of movement of the gravity ball 3. It is installed on the inner wall of the upper part of the circulation pipe body 1 and is located above the gravity ball 3. When the gravity ball 3 passes through the gravity ball stabilizer 18, the gravity ball stabilizer 18 will control the movement speed of the gravity ball 3 to prevent the gravity ball 3 from moving too fast under its inertia. When the gravity ball 3 moves to the gravity ball starting platform 15, the gravity ball stabilizer 18 controls the gravity ball 3 to move only when the gravity ball 3 When the starting platform rotates to the horizontal plane, it starts to fall from the gravity ball starting platform 15; when the piston cylinder rotates clockwise in the vertical plane, the gravity-driven circulation pipeline also rotates clockwise in the vertical plane. When the piston cylinder rotates to the right side of the engine center axis below the horizontal plane, the gravity ball 3 has run to and stopped on the gravity ball starting platform 15. When the piston cylinder rotates to the submerged piston starting angle, the gravity ball starting platform 15 just rotates to the horizontal state. As the piston cylinder rotates further, the gravity ball 3 immediately falls under the action of its own gravity. The gravity ball 3 starts to fall from the starting platform 15 and hits the end of the gravity drive arm 4. The other end of the gravity drive arm 4 drives each transmission mechanism, so that the piston motion controller releases the submerged piston and the submerged piston starts to move. At this time, as the gravity drive arm 4 in the circulation tube body 1 tilts downward, the gravity ball 3 continues to roll rapidly downward along the circulation tube body 1. When the gravity ball 3 rolls to the bottom of the circulation tube body 1, as the piston cylinder continues to rotate, the gravity ball 3 continues to move counterclockwise along the auxiliary tube body on the right side of the circulation tube body 1. When the piston cylinder rotates again When it reaches the right side of the horizontal plane below the central axis of the engine, the gravity ball 3 moves to and stops on the gravity ball starting platform 15 again, and moves back and forth in this way. The gravity ball 3 drives the piston motion controller to release the submerged piston stably and accurately through the gravity drive arm 4 and the transmission mechanism connected thereto, so that the submerged piston can perform a stable and accurate reciprocating motion in a cycle; when the submerged piston cooperates with the piston cylinder of the engine to rotate in the counterclockwise direction, the installation method of the gravity-driven circulation pipeline is a mirror image installation method of the gravity-driven circulation pipeline rotating in the clockwise direction. ;

[0068] See also Figure 1 , Figure 2 and Figure 6 The baffle bridge 2 is a control mechanism installed in the baffle bridge type circulation pipeline and controls the gravity ball 3 to make a one-way circulation movement. The present invention has created two types of baffle bridges, namely, a gear-controlled baffle bridge and a collision-type baffle bridge, wherein:

[0069] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The gear-controlled baffle bridge includes a baffle 19, a baffle gear 20, a gear shaft 21, a bearing, a transmission rack 22, a rack connecting plate 23, a connecting plate shaft 24, a connecting plate support spring 25 and a baffle support frame 26. Two gear-controlled baffle bridges are installed in the circulation tube body, namely, a goal baffle bridge and a return baffle bridge. The baffle bridge close to the gravity ball starting platform 15 and allowing the gravity ball 3 to pass through the baffle bridge 2 and enter the gravity ball starting platform 15 is the goal baffle bridge, and the baffle bridge installed at the lower part of the circulation tube body and allowing the gravity ball 3 to move toward the goal baffle bridge is the return baffle bridge; the lower ends of the baffles 19 on both sides are The support rod is symmetrically connected and fixed on the chord of the two baffle gears 20. The centers of the two baffle gears 20 are respectively installed with gear shafts 21. The gear shafts 21 are respectively connected and fixed on the two inner rings of the bearings. The two outer rings of the bearings are respectively connected and fixed on the lower part of the inner wall of the circulation pipe body 1. The line between the centers of the two baffle gears 20 is horizontal. The two baffle gears 20 are meshed with the two transmission racks 22. The two transmission racks 22 are installed and fixed on the ends of the connecting rods on both sides of the rack connecting plate 23. The two sides of the rack connecting plate 23 are supported by the connecting plate shafts 24. The two connecting plate shafts 24 are respectively connected The rack connecting plate 23 is fixed on the inner rings of the two bearings, and the outer rings of the two bearings are respectively fixed on the lower part of the inner wall of the circulation pipe body 1; two or more connecting plate support springs 25 are installed at the lower part of the other end of the rack connecting plate 23, and the elastic force of all the connecting plate support springs 25 is less than the gravity of the gravity ball 3. When the gravity ball 3 does not pass through the baffle bridge 2, the supporting elastic force of the connecting plate support springs 25 makes the rack connecting plate 23 and the baffle 19 always in a coincident state. When the gravity ball 3 passes through the baffle bridge 2, since the rack connecting plate 23 and the baffle 19 are in a coincident state, the gravity ball 3 passes smoothly from the grooved baffle 19 When the gravity ball 3 passes over the baffle 19 and rolls on the rack connecting plate 23, under the gravity of the gravity ball 3, one end of the rack connecting plate 23 moves downward and compresses the connecting plate support spring 25, while prying the transmission rack 22 at the other end to move upward, and the transmission rack 22 drives the baffle gear 20 to rotate, and the baffle gear 20 drives the baffle 19 to stand up and close to the baffle support frame 26, sealing the pipe opening to prevent the gravity ball 3 from rolling back into the main pipe body. When the gravity ball 3 leaves the baffle bridge 2, under the support of the connecting plate support spring 25, the rack connecting plate 23 and the baffle 19 return to the overlapping state;In the process of the circulation pipe body rotating with the piston cylinder, when the gravity ball starting platform 15 rotates to a horizontal state, the gravity ball 3 begins to fall, and after hitting the gravity driving arm 4, it moves toward the direction of the return ball baffle bridge. When the gravity ball 3 passes over the baffle 19 of the return ball baffle bridge and rolls on the rack connecting plate 23, the gravity ball 3 pushes one end of the rack connecting plate 23 to move downward, and the baffle 19 of the return ball baffle bridge immediately stands up and seals the pipe mouth. With the continuous rotation of the circulation pipe body, the gravity ball 3 uses the grooved baffle 19 as a bridge to roll from the outer pipe wall of the circulation pipe body 1 to the inner pipe wall. With the continuous rotation of the circulation pipe body 1, the gravity ball 3 continues to move in the auxiliary pipe body and The ball 3 passes over the baffle 19 of the goal baffle bridge and rolls on the rack connecting plate 23 of the goal baffle bridge. At this time, the gravity ball 3 pushes the rack connecting plate 23 to move downward, and the baffle 19 of the goal baffle bridge immediately stands up and rests against the baffle support 26 to close the pipe opening. As the circulation pipe body 1 continues to rotate, the gravity ball 3 rolls back onto the grooved baffle 19 and uses the grooved baffle 19 as a bridge to roll onto the gravity ball starting platform 15. At this time, a V-shaped groove body with an opening upward is formed between the grooved baffle 19 and the gravity ball starting platform 15, and the gravity ball 3 stops at the bottom of the V-shaped groove body. As the circulation pipe body 1 continues to rotate, when the gravity ball starting platform 15 rotates to When in the horizontal state, the gravity ball 3 starts to fall, and after hitting the gravity drive arm 4, it moves toward the ball return baffle bridge; the baffle 19 is a grid plate with straight arc grooves on both sides, which can allow the gravity ball 3 to move stably on the straight arc grooves on both sides of the baffle 19, and the rack connecting plate 23 is a straight arc groove grid plate. The cross-sectional curvature radius of the baffle 19 and the rack connecting plate 23 is greater than the curvature radius of the gravity ball 3. The gravity ball 3 rolls along the arc grooves of the baffle 19 and the rack connecting plate 23. Since the baffle 19 and the rack connecting plate 23 rotate in the liquid of the circulation tube body 1, it is necessary to make the baffle 19 and the rack connecting plate 23 capable of A water-permeable mesh plate is provided to reduce the liquid resistance when the baffle 19 and the rack connecting plate 23 rotate. The baffle 19 is formed by orthogonally connecting and fixing a plurality of grooved straight plates with grooves on both sides and a plurality of arc-shaped plates with arcs on both sides, forming a grooved mesh plate with grooves on both sides. The width of the grooved straight plate in the middle is greater than the width of each grooved straight plate on both sides. The rack connecting plate 23 is formed by orthogonally connecting and fixing a plurality of grooved straight plates and a plurality of arc-shaped plates, forming a grooved mesh plate. The width of the grooved straight plate in the middle is greater than the width of each grooved straight plate on both sides, so that the gravity ball 3 can stably roll on the grooved baffle 19 and the grooved rack connecting plate 23;

[0070] See also Figure 6The impact-type baffle bridge includes an impact-type baffle 27, an impact-type baffle rotating shaft 28, a bearing, a torsion spring and a baffle support 26. Two impact-type baffle bridges are installed in the circulation tube body 1, namely, a goal baffle bridge and a return baffle bridge. The baffle bridge close to the gravity ball starting platform 15 and allowing the gravity ball 3 to move to the gravity ball starting platform 15 through the baffle bridge 2 is the goal baffle bridge, and the baffle bridge installed at the lower part of the circulation tube body and allowing the gravity ball 3 to move toward the goal baffle bridge is the return baffle bridge; the impact baffle is a straight groove-shaped grid plate, the curvature radius of the cross section of the impact baffle 27 is greater than the curvature radius of the gravity ball 1, one end of the impact baffle 27 is connected and fixed on the impact baffle rotating shaft 28, and the impact baffle A miniature torsion spring is connected in series at each end of the plate shaft 28, one end of the torsion spring is connected and fixed to the impact baffle 27, and the other end is connected and fixed to the inner wall of the circulation pipe body 1. The torsion spring can assist the impact baffle 27 to close the pipe opening. The ends of the impact baffle shaft 28 are connected and fixed in series on two inner rings of bearings, and the two outer rings of bearings are installed and fixed on the inner wall of the inner wall of the circulation pipe body. The impact baffle 27 can rotate around the impact baffle shaft 28 and the bearings; in the process of the circulation pipe body rotating with the piston cylinder, when the gravity ball starting platform 15 rotates to a horizontal state, the gravity ball 3 starts to fall from the gravity ball starting platform 15, and after impacting the gravity driving arm 4, it moves to the lower part of the main body of the circulation pipe body. The gravity ball 3 moves and hits the impact baffle 27 of the ball return baffle bridge and then rolls to the bottom of the main pipe body. At this time, as the circulation pipe body 1 continues to rotate, the main pipe body gradually tends to a horizontal state. In this process, the impact baffle 27 of the ball return baffle bridge rotates to the baffle support frame 26 in advance under the action of its own gravity and the elastic force of the torsion spring, closing the pipe mouth. The gravity ball 3 begins to roll back onto the impact baffle 27, and uses the groove-shaped impact baffle 27 as a bridge to roll from the outer pipe wall of the circulation pipe body 1 to the inner pipe wall. As the circulation pipe body continues to rotate, the gravity ball 3 moves along the auxiliary pipe body to the goal baffle bridge, hits the impact baffle 27 of the goal baffle bridge and then moves to the bottom of the auxiliary pipe body. As the circulation pipe body continues to rotate, the gravity ball 3 moves to the goal baffle bridge along the auxiliary pipe body, hits the impact baffle 27 of the goal baffle bridge and then moves to the bottom of the auxiliary pipe body. Rotation, the impact baffle 27 of the ball baffle bridge rotates to the baffle support 26 in advance under the action of its own gravity and the elastic force of the torsion spring, closing the pipe mouth, and the gravity ball 3 begins to roll back onto the impact baffle 27, and uses the groove-shaped impact baffle 27 as a bridge to roll from the outer wall of the circulation pipe body to the gravity ball starting platform 15. At this time, a V-shaped groove body with an opening upward is formed between the groove-shaped impact baffle 27 and the gravity ball starting platform 15, and the gravity ball 3 stops at the bottom of the V-shaped groove body. As the circulation pipe body 1 continues to rotate, when the gravity ball starting platform 15 rotates to a horizontal state, the gravity ball 3 begins to fall, and after impacting the gravity driving arm 4, it moves in the opposite direction to the ball return baffle bridge;Since the impact baffle 27 rotates in the liquid of the circulation tube body, the impact baffle 27 needs to be made into a water-permeable mesh plate to reduce the liquid resistance when the impact baffle 27 rotates. The impact baffle 27 is made of a plurality of grooved straight plates and a plurality of arc plates connected and fixed orthogonally to form a grooved mesh plate. The width of the middle grooved straight plate is greater than the width of each grooved straight plate on both sides, so that the gravity ball 3 can roll stably on the grooved straight plate; the impact baffle 27 is made of high-strength, lightweight, and wear-resistant material. ;

[0071] See also Figure 1 and Figure 7 The gravity-driven arm 4 is a zigzag rod-shaped mechanism with one end located in the rectangular opening of the circulation pipe body 1 and the other end connected to the end of the transmission arm 6, and supported in the middle by the gravity-driven arm support column 5. The gravity-driven arm 4 has two construction and support methods, namely, the gravity-driven arm construction and support method based on the baffle bridge circulation pipeline and the gravity-driven arm construction and support method based on the gravity-driven circulation pipeline, wherein:

[0072] See also Figure 1 and Figure 2 The gravity drive arm 4 of the baffle bridge type circulation pipeline is constructed and supported in this way. Since the auxiliary pipe body of the circulation pipe body 1 is located on the left side of the main pipe body with a rectangular opening, and the other end of the gravity drive arm 4 is also located on the left side of the main pipe body with a rectangular opening, when both are located on the left side of the main pipe body, the gravity drive arm 4 leaving the rectangular opening is divided into two drive arms and made into an annular gravity drive arm 4, and the auxiliary pipe body on the left side is sleeved in the annular gravity drive arm 4, so that the gravity drive arm 4 can be tilted up and down. For oblique movement, the other end of the gravity-driven arm 4 is combined to form a driving arm, and the end connected to the transmission arm 6 is made into a short rod perpendicular to the gravity-driven arm 4. The gravity-driven arm 4 is supported by a gravity-driven arm support column 5. The gravity-driven arm support column 5 can be installed inside the circulation pipe body 1 or outside the circulation pipe body 1. The two supporting methods make the arm lengths of the gravity-driven arm 4 on both sides of the fulcrum of the gravity-driven arm support column 5 different. The specific support point selection needs to be calculated and determined according to the arm length requirements of the gravity-driven arm 4 on both sides of the support point;

[0073] See also Figure 7 and Figure 8The gravity-driven arm 4 of the gravity-driven circulation pipeline is constructed and supported in such a way that the auxiliary pipe body of the circulation pipe body 1 is located on the right side of the main pipe body with a rectangular opening, and the other end of the gravity-driven arm 4 is located on the left side of the main pipe body with a rectangular opening, and the two are in opposite directions. Therefore, the gravity-driven arm 4 is a straight, complete rod-shaped mechanism, and the end connected to the transmission arm 6 is made into a short rod perpendicular to the gravity-driven arm 4. The middle part of the gravity-driven arm 4 is supported by the gravity arm support column 5. The specific support point selection needs to be calculated and determined based on the arm length requirements of the gravity-driven arm 4 on both sides of the support point.

[0074] See also Figure 2 and Figure 8 The end rod section of the gravity driving arm 4 located in the rectangular opening of the circulation tube body 1 is evenly provided with a plurality of small holes. Since the gravity driving arm 4 rotates in the liquid of the circulation tube body, when the gravity ball 3 hits the end of the gravity driving arm 4, the gravity driving arm 4 quickly tilts downward. At this time, the liquid in the circulation tube body 1 flows out from all the small holes. On the one hand, the resistance of the liquid to the downward tilting movement of the gravity driving arm 4 is reduced. On the other hand, the liquid emerging from the small holes directly pushes the gravity ball 3 away from the circulation tube body 1. The gravity driving arm 4 is opened to accelerate the falling speed of the gravity ball 3; at the same time, a gravity ball blocking plate 17 is installed and fixed on the gravity driving arm 4 located in the rectangular opening of the circulation tube body 1, and the gravity ball blocking plate 17 is close to the inner side of the rectangular opening of the circulation tube body 1 to prevent the gravity ball 3 from accidentally escaping from the circulation tube body 1. The gravity ball blocking plate 17 is an arc-shaped straight plate, and the curvature radius and arc direction of the gravity ball blocking plate 17 are the same as the curvature radius and arc direction of the inner tube wall of the circulation tube body 1.

[0075] See also Figure 1 , Figure 2 , Figure 7 and Figure 8The gravity ball starting platform 15 is a groove-shaped straight platform mechanism that controls the gravity ball 3 to start falling and collide with the end of the gravity driving arm 4 according to the set submerged piston starting angle. The gravity ball starting platform 15 is close to the goal baffle bridge, and its surface is designed and made into an arc-shaped groove-shaped straight surface. The lines connecting the two sides of the gravity ball starting platform 15 perpendicular to the upper edge of the arc groove are in a horizontal state. The curvature radius of the arc groove is variable. The curvature radius of the arc groove close to the goal baffle bridge is close to the curvature radius of the gravity ball 3, increasing the contact area between the gravity ball 3 and the arc groove. The curvature radius of the arc groove in the direction of the gravity ball 3 rolling down gradually increases, reducing the contact area between the gravity ball 3 and the arc groove, so as to ensure the stability of the gravity ball 3 when it stops on the gravity ball starting platform 15, and to ensure that the gravity ball 3 can fall At the same time, a high-strength and wear-resistant anti-vibration and anti-skid material is laid on the gravity ball starting platform 15 to ensure the stability and accuracy of the gravity ball 3 rolling on the platform; the starting position of the gravity ball 3 is based on the position of the set submerged piston starting angle, that is, the starting angle of the submerged piston is the angle between the piston cylinder of the submerged piston cooperative driving engine and the vertical line of the engine center axis as the starting angle. When the piston cylinder rotates to the set starting angle, the gravity ball starting platform 15 is just in a horizontal state. When the piston cylinder rotates further, the gravity ball 3 immediately starts to fall and hits the gravity drive arm 4. The other end of the gravity drive arm 4 drives the transmission mechanism connected thereto to control the piston motion controller to release the submerged piston, allowing the submerged piston to start moving.

[0076] A method for controlling a submersible piston at a fixed angle is disclosed. The fixed angle control of the submersible piston is performed by periodically colliding a gravity drive arm 4 with a gravity ball 3 according to a set starting angle and starting position of the submersible piston. The gravity drive arm 4 drives a piston motion controller to release the submersible piston through a transmission mechanism connected thereto, so that the submersible piston starts to move, thereby realizing periodic reciprocating motion of the submersible piston, and achieving the purpose of controlling the submersible piston to coordinately drive the engine speed. The specific control method is as follows:

[0077] (1) Calculate and determine the number and weight of the submersible pistons. The speed and power of the submersible piston cooperative drive engine are determined by the number, length, shape, capacity of the piston cylinders, the height and weight of the liquid in the piston cylinders and the gravity box, and the volume and weight of the submersible pistons. After the design speed and design power of the submersible piston cooperative drive engine are determined, first calculate and determine the number, length, shape, capacity of the piston cylinders, and the height and weight of the liquid in the piston cylinders and the gravity box. Then, the number and weight of the submersible pistons can be calculated and determined;

[0078] (2) Design and establish that the buoyancy of the submersible piston immersed in the liquid is greater than its own weight. When designing and manufacturing the submersible piston, by calculating the volume and buoyancy of the submersible piston and the gravity of the gravity body 3 of the submersible piston and all other mechanisms and components, the buoyancy of the submersible piston in the liquid is designed to be greater than its own weight, so that the submersible piston always has the ability to float in the liquid of the piston cylinder;

[0079] (3) Calculate and determine the effective length and one-way motion time of the submerged piston in the piston barrel. Based on the length of the piston barrel and the distance from the piston control top of the piston motion controller installed at both ends of the piston barrel to the inner wall of the piston barrel end, the effective length of the submerged piston in the piston barrel can be calculated and determined. Based on the buoyancy calculation formula and the physical kinematics formula, the one-way motion time of the submerged piston in the piston barrel when the piston barrel is perpendicular to the horizontal plane or at other angles to the horizontal plane can be calculated and determined, providing a basis for determining the starting angle when the submerged piston starts to move; the one-way motion time of the submerged piston in the piston barrel determines the speed of the engine. If the one-way motion time of the submerged piston in the piston barrel cannot meet the design speed requirement of the engine, it is necessary to recalculate and adjust the volume of the submerged piston, that is, change the liquid buoyancy of the submerged piston until the design speed requirement of the engine is met;

[0080] (4) Calculate the starting angle for the submersible piston to start moving. After calculating and determining the one-way movement time of the submersible piston in the piston cylinder, the rotation angle of the piston cylinder during the one-way movement time of the submersible piston can be calculated based on the speed of the engine driven by the submersible piston. The principle is to maximize the torque difference between the submersible piston on the left and right sides of the vertical line of the engine center axis, and the angle between the piston cylinder and the vertical line of the engine center axis is used as the starting angle when the submersible piston starts moving. The position of the piston cylinder in the vertical rotation plane is determined, and the position of the piston cylinder is used as the starting position for the submersible piston to start moving.

[0081] (5) Setting the horizontal position of the gravity ball starting platform 15. The horizontal position of the gravity ball starting platform 15 is the position corresponding to the set starting angle of the submerged floating piston when the piston cylinder rotates, that is, when the piston cylinder rotates to the position corresponding to the starting angle of the submerged floating piston, the gravity ball starting platform 15 is just in a horizontal state. As the piston cylinder continues to rotate, the gravity ball 3 immediately starts to fall from the gravity ball starting platform 15 and hits the gravity drive arm 4. The gravity drive arm 4 drives the two clamping crank arms of the piston motion controller through the transmission mechanism connected thereto to release the submerged floating piston, allowing the submerged floating piston to start floating.

[0082] (6) Calculate and determine the arm lengths of the gravity drive arm 4, the transmission arm 6, and the start arm 8 and the movement distance of the crank arm control ring. The gravity drive arm 4 is connected to the transmission arm 6 and the start arm 8, and the middle part of each transmission mechanism is supported by a support column. The start arm 8 is connected to the crank arm control ring of the piston motion controller, and drives the crank arm control ring together with the crank arm sliding sleeve to move in the direction of the submerged piston, drives the clamping end of the clamping crank arm to release the submerged piston, and allows the submerged piston to start moving. This requires the calculation and determination of the arm lengths at both ends of each support point of the gravity drive arm 4, the transmission arm 6, and the start arm 8 and the distance that the crank arm control ring and the crank arm sliding sleeve drive the clamping end of the clamping crank arm to release the submerged piston based on the principles of accuracy, efficiency, and labor saving, so that the driving force can be effectively transmitted and driven between the gravity drive arm 4 and the transmission mechanism connected thereto;

[0083] (7) Calculate and determine the weight of the gravity ball 3. The gravity of the gravity ball 3 is used to drive the gravity drive arm 4 and the transmission mechanism connected thereto, and overcome the elastic tension of the stabilizing control spring 14 and the crank arm spring of the piston motion controller. After determining the force arm length and movement distance of the gravity drive arm 4 and the transmission mechanism connected thereto, as well as the elastic tension of the stabilizing control spring 14 and the crank arm spring, the weight of the gravity ball 3 can be calculated and determined, so that the gravity ball 3 can successfully complete the driving task;

[0084] (8) Automatically control the start-up and unidirectional circulation of the gravity ball 3. The gravity ball 3 is a spherical component that performs unidirectional circulation in the circulation pipe body 1 and collides with the gravity drive arm 4. The piston fixed angle control switch can adopt a baffle bridge type circulation pipeline or a gravity drive type circulation pipeline. When the baffle bridge type circulation pipeline is adopted, when the piston cylinder rotates to the position corresponding to the starting angle of the submerged piston, the gravity ball starting platform 15 is just in a horizontal state, and the gravity ball 3 is located on the gravity ball starting platform 15. As the piston cylinder rotates further, the gravity ball 3 immediately starts to fall from the gravity ball starting platform 15, and after colliding with the gravity drive arm 4, it continues to move to the bottom of the circulation pipe body 1 and passes over the baffle of the ball return baffle bridge. At this time, the baffle is erected and closed. The pipe opening is closed. As the piston cylinder continues to rotate, the gravity ball 3 begins to roll back and enters the auxiliary pipe body of the circulation pipe body through the grooved baffle. As the piston cylinder continues to rotate, the gravity ball 3 moves toward the goal baffle bridge and crosses the baffle of the goal baffle bridge. At this time, the baffle is erected and the pipe opening is closed. As the piston cylinder continues to rotate, the gravity ball begins to roll back and moves to the bottom of the groove between the grooved baffle of the goal baffle bridge and the gravity ball starting platform 15.

When the submersible piston cooperates to drive the piston cylinder of the engine to rotate in the vertical plane, the baffle bridge circulation pipeline also rotates in the vertical plane. When the piston cylinder rotates to the right side of the horizontal plane below the central axis of the engine, the gravity ball has run to and stopped on the gravity ball starting platform. When the piston cylinder rotates to the starting angle of the submersible piston, the gravity ball stops at the starting platform. The ball starter platform just rotates to a horizontal state. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starter platform under the action of its own gravity and hits the end of the gravity drive arm. The other end of the gravity drive arm drives each transmission mechanism, so that the piston motion controller releases the submerged piston and starts the submerged piston to move. At this time, as the gravity drive arm in the circulation pipe body tilts downward, the gravity ball continues to roll rapidly downward along the circulation pipe body. When the submerged piston cooperates with the piston cylinder of the engine to rotate counterclockwise, the installation method of the baffle bridge type circulation pipeline is a mirror image installation method of the baffle bridge type circulation pipeline rotating in the clockwise direction. The gravity-driven circulation pipeline is a circulation pipeline that is driven by the gravity ball's own gravity, through the construction of a circulation pipe body shape that adapts to the unidirectional circulation movement of the gravity ball, the construction of a pipe wall shape for the rolling of the gravity ball and the control of a gravity ball stabilizer, so that the gravity ball can stably and accurately perform unidirectional circulation movement. The gravity-driven circulation pipeline includes a circulation pipe body, a gravity ball starting platform, a gravity ball stabilizer and a circulation pipe support column. The circulation pipe body refers to a circulation pipe body that adapts to the gravity ball to perform unidirectional circulation movement along the circulation pipe body in the opposite direction to the rotation of the piston cylinder under the drive of its own gravity during the rotation of the piston cylinder. The main pipe body of the circulation pipe body is a straight pipe, and the auxiliary pipe body is an arc pipe. The main pipe body and the auxiliary pipe body of the circulation pipe body may be in the same plane or not. The plane of the circulation tube body where the main tube body and the auxiliary tube body are in the same plane is parallel to the rotation plane of the piston cylinder, and the main tube body and the auxiliary tube body that are not in the same plane are staggered, so that the tube wall slope of the entire auxiliary tube body becomes gentle during the rotation of the piston cylinder, thereby slowing down the movement speed of the gravity ball in the circulation tube body, ensuring the stability of the gravity ball movement, the cross-sectional inner diameter of the circulation tube body is larger than the diameter of the gravity ball, and the cross-sectional shape and size of each tube section of the entire circulation tube body are different.

The stabilizing mechanism which can flexibly rotate in the direction of the ball's movement is installed on the inner wall of the upper part of the circulation pipe body and is located above the gravity ball. When the gravity ball passes through the gravity ball stabilizer, the gravity ball stabilizer will control the movement speed of the gravity ball to prevent the gravity ball from moving too fast under the action of its inertia. When the gravity ball moves to the gravity ball starting platform, the gravity ball stabilizer controls the gravity ball to start falling from the gravity ball starting platform only when the gravity ball starting platform rotates to the horizontal plane. When the piston cylinder rotates clockwise in the vertical plane, the gravity-driven circulation pipeline also rotates clockwise in the vertical plane. When the piston cylinder rotates to below the horizontal plane on the right side of the engine center axis, the gravity ball has run to and stopped on the gravity ball starting platform. When the piston cylinder rotates to the submerged piston starting angle,The gravity ball starting platform just rotates to a horizontal state. As the piston cylinder rotates further, the gravity ball immediately begins to fall from the gravity ball starting platform under the action of its own gravity and hits the end of the gravity drive arm. The other end of the gravity drive arm drives each transmission mechanism, causing the piston motion controller to release the submerged piston and start the submerged piston to move. At this time, as the gravity drive arm in the circulation tube body tilts downward, the gravity ball continues to roll rapidly downward along the circulation tube body. When the gravity ball rolls to the bottom of the circulation tube body, as the piston cylinder continues to rotate, the gravity ball continues to roll along the auxiliary tube body on the right side of the circulation tube body.

The gravity ball drives the piston motion controller to release the submerged piston stably and accurately through the gravity drive arm and the transmission mechanism connected to it, so that the submerged piston can perform stable and accurate reciprocating motion. When the submerged piston cooperates to drive the engine's piston cylinder to rotate counterclockwise, the installation method of the gravity-driven circulation pipeline is a mirror image installation method of the gravity-driven circulation pipeline rotating clockwise.

3. The piston fixed angle control switch according to claim 2, characterized in that: The baffle bridge is installed in the baffle bridge type circulation pipeline, and is used to control the gravity ball to make a one-way circulation movement. It includes two types of baffle bridges, namely, a gear-controlled baffle bridge and a collision-type baffle bridge, wherein: The gear-controlled baffle bridge includes a baffle, a baffle gear, a gear shaft, a bearing, a transmission rack, a rack connecting plate, a connecting plate shaft, a connecting plate supporting spring and a baffle bracket. Two gear-controlled baffle bridges are installed in the circulation tube body, namely, a goal baffle bridge and a return ball baffle bridge. The baffle bridge close to the gravity ball starting platform and allowing the gravity ball to move to the gravity ball starting platform through the baffle bridge is the goal baffle bridge, and the baffle bridge installed at the lower part of the circulation tube body and allowing the gravity ball to move toward the goal baffle bridge is the return ball baffle bridge. The support rods at the lower ends of both sides of the baffle are symmetrically connected and fixed on the chords of the two baffle gears, and the gear shafts are respectively installed at the centers of the two baffle gears. The gear shafts are respectively connected and fixed on the two inner rings of the bearings, and the two outer rings of the bearings are respectively connected and fixed on the circulation tube body. At the lower part of the inner wall of the tube body, the line between the centers of the two baffle gears is horizontal, the two baffle gears are meshed with the two transmission racks, and the two transmission racks are installed and fixed to the ends of the connecting rods on both sides of the rack connecting plate. The two sides of the rack connecting plate are supported by the connecting plate rotating shaft, and the two connecting plate rotating shafts are respectively connected and fixed to the two bearing inner rings, and the two bearing outer rings are respectively connected and fixed to the lower part of the inner wall of the circulation tube body, and two or more connecting plate support springs are installed at the lower part of the other end of the rack connecting plate. The elastic force of all the connecting plate support springs is less than the gravity of the gravity ball. When the gravity ball does not pass through the baffle bridge, the supporting elastic force of the connecting plate support spring makes the rack connecting plate and the baffle always in an overlapping state. When the gravity ball passes through the baffle bridge, since the rack connecting plate and the baffle are in a state of gravity The gear train of the gearbox is in a closed state, so that the gravity ball passes smoothly through the grooved baffle. When the gravity ball passes over the baffle and rolls on the rack connecting plate, under the gravity of the gravity ball, one end of the rack connecting plate moves downward and compresses the connecting plate supporting spring, while prying the transmission rack at the other end to move upward. The transmission rack drives the baffle gear to rotate, and the baffle gear drives the baffle to stand up and close to the baffle support frame, sealing the pipe opening to prevent the gravity ball from rolling back into the main pipe body. After the gravity ball leaves the baffle bridge, under the support of the connecting plate supporting spring, the rack connecting plate and the baffle return to the overlapping state. In the process of the circulating pipe body rotating with the piston cylinder, when the gravity ball starting platform rotates to a horizontal state, the gravity ball begins to fall, and after hitting the gravity driving arm, it moves toward the direction of the return ball baffle bridge. When the gravity ball passes over the baffle of the ball return baffle bridge and rolls on the rack connecting plate, the gravity ball pushes one end of the rack connecting plate to move downward, and the baffle of the ball return baffle bridge immediately stands up and seals the pipe opening. As the circulation pipe body continues to rotate, the gravity ball uses the grooved baffle as a bridge to roll from the outer pipe wall of the circulation pipe body to the inner pipe wall. As the circulation pipe body continues to rotate, the gravity ball continues to move in the auxiliary pipe body and passes over the baffle of the goal baffle bridge and rolls on the rack connecting plate of the goal baffle bridge. At this time, the gravity ball pushes the rack connecting plate to move downward, and the baffle of the goal baffle bridge immediately stands up and presses against the baffle support frame to close the pipe opening. As the circulation pipe body continues to rotate, the gravity ball rolls back to the grooved baffle, and uses the grooved baffle as a bridge to roll to the gravity ball starting platform. At this time,A V-shaped groove body with an opening upward is formed between the groove-shaped baffle plate and the gravity ball starting platform. The gravity ball stops at the bottom of the V-shaped groove body. As the circulation tube body continues to rotate, when the gravity ball starting platform rotates to a horizontal state, the gravity ball begins to fall, and after hitting the gravity driving arm, it moves toward the direction of the ball return baffle bridge. The baffle plate is a groove-shaped grid plate with both sides being straight, which can allow the gravity ball to stably move on the straight arc grooves on both sides of the baffle plate, that is, the baffle plate is formed by orthogonally connecting and fixing a plurality of groove-shaped straight plates with both sides being grooved and a plurality of arc-shaped plates with both sides being arc-shaped, forming a baffle plate with both sides being straight. The groove-shaped groove grid plate, the width of the middle groove straight plate is greater than the width of each groove straight plate on both sides, the rack connecting plate is formed by orthogonally connecting and fixing a plurality of groove straight plates and a plurality of arc-shaped plates, forming a groove grid plate, the width of the middle groove straight plate is greater than the width of each groove straight plate on both sides, so that the gravity ball can roll stably on the groove baffle plate and the groove rack connecting plate, the construction of the grid baffle plate and the rack connecting plate can reduce the liquid resistance when the baffle plate and the rack connecting plate rotate, and the cross-sectional curvature radius of the baffle plate and the rack connecting plate is greater than the curvature radius of the gravity ball;, The impact-type baffle bridge includes an impact baffle, an impact baffle rotating shaft, a bearing, a torsion spring and a baffle support. Two impact-type baffle bridges are installed in the circulation tube body, namely, a goal baffle bridge and a return ball baffle bridge. The baffle bridge close to the gravity ball starting platform and allowing the gravity ball to move to the gravity ball starting platform through the baffle bridge is the goal baffle bridge, and the baffle bridge installed at the lower part of the circulation tube body and allowing the gravity ball to move toward the goal baffle bridge is the return ball baffle bridge. The impact baffle is a straight grooved grid plate made of light hard wear-resistant material. The curvature radius of the cross section of the impact baffle is greater than the curvature radius of the gravity ball. One end of the impact baffle is connected and fixed to the impact baffle rotating shaft. A miniature torsion spring is connected in series at each end of the impact baffle rotating shaft. One end of the torsion spring is connected and fixed to the impact baffle. The other end is connected and fixed on the inner wall of the circulation pipe body. The torsion spring can assist the impact baffle to close the pipe opening. The ends of the impact baffle rotating shaft are connected and fixed on the two inner rings of the bearings in series. The two outer rings of the bearings are installed and fixed on the inner wall of the pipe wall in the circulation pipe body. The impact baffle can flexibly rotate around the impact baffle rotating shaft and the bearings. In the process of the circulation pipe body rotating with the piston cylinder, when the gravity ball starting platform rotates to a horizontal state, the gravity ball starts to fall from the gravity ball starting platform, and moves to the lower part of the main body of the circulation pipe body after hitting the gravity driving arm, and rolls to the bottom of the main body after hitting the impact baffle of the return ball baffle bridge. At this time, as the circulation pipe body continues to rotate, the main body gradually tends to a horizontal state. In this process, the impact baffle of the return ball baffle bridge is under its own weight. The gravity ball begins to roll back to the impact baffle plate, and uses the groove-shaped impact baffle plate as a bridge to roll from the outer tube wall of the circulation tube body to the inner tube wall. As the circulation tube body continues to rotate, the gravity ball quickly moves along the auxiliary tube body to the goal baffle plate bridge, and hits the impact baffle plate of the goal baffle plate bridge and then moves to the bottom of the auxiliary tube body. As the circulation tube body continues to rotate, the impact baffle plate of the goal baffle plate bridge, under the action of its own gravity and the elastic force of the torsion spring, first rotates to the baffle plate support frame to close the pipe mouth. The gravity ball begins to roll back to the impact baffle plate, and uses the groove-shaped impact baffle plate as a bridge to roll from the outer tube wall of the circulation tube body to the gravity ball starting platform. At this time, the groove-shaped impact baffle plate and the gravity ball starting platform are connected. A V-shaped groove body with an opening upward is formed in the middle, and the gravity ball stops at the bottom of the V-shaped groove body. As the circulation tube body continues to rotate, when the gravity ball starting platform rotates to a horizontal state, the gravity ball begins to fall, and after hitting the gravity driving arm, it moves toward the ball return baffle bridge. Since the impact baffle rotates in the liquid of the circulation tube body, it is necessary to make the impact baffle into a water-permeable grid plate to reduce the liquid resistance when the impact baffle rotates. The impact baffle is formed by a number of grooved straight plates and a number of arc-shaped rods orthogonally connected and fixed to form a semicircular grooved grid plate. The width of the middle grooved straight plate is greater than the width of each grooved straight plate on both sides, so that the gravity ball can roll stably on the grooved straight plate. The impact baffle is made of high-strength, lightweight and wear-resistant material.

The two support methods make the arm lengths of the gravity drive arms on both sides of the fulcrum of the gravity arm support column different, and the specific support point selection needs to be calculated and determined according to the arm length requirements of the gravity drive arms on both sides of the support point; The gravity-driven arm construction and support method based on the gravity-driven circulation pipeline is as follows: the auxiliary tube body of the circulation tube body is located on the right side of the main tube body with a rectangular opening, and the other end of the gravity-driven arm is located on the left side of the main tube body with a rectangular opening, and the two are in opposite directions. Therefore, the gravity-driven arm is a straight, complete rod-shaped mechanism, and the end connected to the transmission arm is made into a short rod perpendicular to the gravity-driven arm. The middle part of the gravity-driven arm is supported by the gravity arm support column, and the specific support point selection needs to be calculated and determined based on the arm length requirements of the gravity-driven arm on both sides of the support point.

On the one hand, the resistance of the liquid to the downward tilting movement of the gravity driving arm is reduced. On the other hand, the liquid emerging from the small holes directly pushes the gravity ball to leave the gravity driving arm, thereby accelerating the falling speed of the gravity ball. At the same time, a gravity ball blocking plate is fixedly installed on the gravity driving arm located in the rectangular opening of the circulation tube body. The gravity ball blocking plate is close to the inner side of the rectangular opening of the circulation tube body to prevent the gravity ball from accidentally leaving the circulation tube body.

The lines connecting the two sides of the gravity ball starting platform perpendicular to the upper edge of the arc groove are in a horizontal state, and the curvature radius of the arc groove is variable. The curvature radius of the arc groove close to the goal baffle bridge is close to the curvature radius of the gravity ball, thereby increasing the contact area between the gravity ball and the arc groove, and the curvature radius of the arc groove in the direction of the gravity ball rolling down gradually increases, thereby reducing the contact area between the gravity ball and the arc groove, thereby ensuring the stability of the gravity ball when it stops on the gravity ball starting platform, and ensuring that the gravity ball can fall quickly. At the same time, high-strength and wear-resistant anti-vibration and anti-skid materials are laid on the gravity ball starting platform to ensure the stability and accuracy of the gravity ball rolling on the platform. The starting position of the gravity ball is based on the position of the set submerged piston starting angle, that is, the starting angle of the submerged piston is the angle between the piston cylinder of the submerged piston cooperative driving engine and the vertical line of the engine center axis. When the piston cylinder rotates to the set starting angle, the gravity ball starting platform is just in a horizontal state. When the piston cylinder rotates further, the gravity ball immediately starts to fall and hits the gravity drive arm. The other end of the gravity drive arm drives the transmission mechanism connected to it to control the piston movement controller to release the submerged piston, and the submerged piston starts to move.

7. A method for controlling a submersible piston fixed angle, characterized in that: The fixed angle control of the submersible piston is to use the gravity ball to periodically collide with the gravity drive arm according to the set starting angle and starting position of the submersible piston. The gravity drive arm drives the piston motion controller to release the submersible piston through the transmission mechanism connected thereto, so that the submersible piston starts to move, thereby realizing the periodic reciprocating motion of the submersible piston, and achieving the purpose of controlling the submersible piston to coordinately drive the engine speed. The specific control method is as follows: (1) Calculate and determine the number and weight of the submersible pistons. The speed and power of the submersible piston cooperative drive engine are determined by the number, length, shape, capacity of the piston cylinders, the height and weight of the piston cylinders and the liquid in the gravity box, and the volume and weight of the submersible pistons. After the design speed and design power of the submersible piston cooperative drive engine are determined, first calculate and determine the number, length, shape, capacity of the piston cylinders, and the height and weight of the piston cylinders and the liquid in the gravity box. Then, the number and weight of the submersible pistons can be calculated and determined; (2) Design and establish that the buoyancy of the submersible piston immersed in the liquid is greater than its own weight. When designing and manufacturing the submersible piston, the buoyancy of the submersible piston in the liquid is designed to be greater than its own weight by calculating the volume, buoyancy, and gravity of the submersible piston and all other mechanisms and components, so that the submersible piston always has the ability to float upward in the liquid in the piston cylinder; (3) Calculate and determine the effective length and one-way motion time of the submerged piston in the piston cylinder. According to the length of the piston cylinder and the distance from the piston control top of the piston motion controller installed at both ends of the piston cylinder to the inner wall of the piston cylinder end, the effective length of the submerged piston in the piston cylinder can be calculated and determined. According to the buoyancy calculation formula and the physical kinematics formula, the one-way motion time of the submerged piston in the piston cylinder when the piston cylinder is perpendicular to the horizontal plane or at other angles to the horizontal plane can be calculated and determined, providing a basis for determining the starting angle when the submerged piston starts to move. The one-way motion time of the submerged piston in the piston cylinder determines the speed of the engine. If the one-way motion time of the submerged piston in the piston cylinder cannot meet the design speed requirement of the engine, it is necessary to recalculate and adjust the volume of the submerged piston, that is, change the liquid buoyancy of the submerged piston until the design speed requirement of the engine is met; (4) Calculating the starting angle of the submersible piston at the beginning of its movement. After calculating and determining the one-way movement time of the submersible piston in the piston cylinder, the rotation angle of the piston cylinder during the one-way movement time of the submersible piston can be calculated based on the rotation speed of the engine driven by the submersible piston. The principle is to maximize the torque difference between the submersible piston on the left and right sides of the vertical line of the engine center axis, and the angle between the piston cylinder and the vertical line of the engine center axis is used as the starting angle when the submersible piston starts to move. The position of the piston cylinder in the vertical rotation plane is determined, and the position of the piston cylinder is used as the starting position for the submersible piston to start moving. (5) Setting the horizontal position of the gravity ball starting platform. The horizontal position of the gravity ball starting platform is the position corresponding to the starting angle of the submerged floating piston when the piston cylinder rotates to the set position. That is, when the piston cylinder rotates to the position corresponding to the starting angle of the submerged floating piston, the gravity ball starting platform is just in a horizontal state. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform and hits the gravity driving arm. The gravity driving arm drives the two clamping crank arms of the piston motion controller through the transmission mechanism connected thereto to release the submerged floating piston, so that the submerged floating piston starts to float upward. (6) Calculate and determine the arm lengths of the gravity drive arm, the transmission arm, and the start arm, and the movement distance of the crank arm control ring. The gravity drive arm is connected to the transmission arm and the start arm, and the middle part of each transmission mechanism is supported by a support column. The start arm is connected to the crank arm control ring of the piston motion controller, and drives the crank arm control ring together with the crank arm sliding sleeve to move toward the submerged piston, drives the clamping end of the clamping crank arm to release the submerged piston, and allows the submerged piston to start moving. This requires calculating and determining the arm lengths of the gravity drive arm, the transmission arm, and the start arm at both ends of each support point, and the distance that the crank arm control ring and the crank arm sliding sleeve need to move to drive the clamping end of the clamping crank arm to release the submerged piston, based on the principles of accuracy, efficiency, and effort saving, so that the gravity drive arm and the transmission mechanism connected thereto can effectively transmit driving force and effectively drive. (7) Calculate and determine the weight of the gravity ball. The gravity of the gravity ball is used to drive the gravity drive arm and the transmission mechanism connected thereto, and overcome the elastic tension of the stabilizing control spring and the crank arm spring of the piston motion controller. After determining the force arm length and movement distance of the gravity drive arm and the transmission mechanism connected thereto, as well as the elastic tension of the stabilizing control spring and the crank arm spring, the weight of the gravity ball can be calculated and determined, so that the gravity ball can successfully complete the driving task; (8) Automatically control the start-up and unidirectional circulation of the gravity ball. The gravity ball is a spherical component that performs unidirectional circulation in the circulation pipe body and collides with the gravity drive arm. The piston fixed angle control switch can adopt a baffle bridge type circulation pipe or a gravity drive type circulation pipe. When the baffle bridge type circulation pipe is adopted, when the piston cylinder rotates to the position corresponding to the starting angle of the submerged piston, the gravity ball starting platform is just in a horizontal state, and the gravity ball is located on the gravity ball starting platform. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform, and after colliding with the gravity drive arm, it continues to move to the bottom of the circulation pipe body and crosses the ball return baffle bridge. The baffle of the goal baffle bridge is erected, and at this time, the baffle is erected and the pipe mouth is closed. As the piston cylinder continues to rotate, the gravity ball begins to roll back and enters the auxiliary pipe body of the circulation pipe body through the grooved baffle. As the piston cylinder continues to rotate, the gravity ball moves toward the goal baffle bridge and crosses the baffle of the goal baffle bridge. At this time, the baffle is erected and the pipe mouth is closed. As the piston cylinder continues to rotate, the gravity ball begins to roll back and moves to the bottom of the groove between the grooved baffle of the goal baffle bridge and the gravity ball starting platform. When the piston cylinder rotates to the position corresponding to the starting angle of the submerged piston, the gravity ball immediately begins to fall from the gravity ball starting platform and hits the gravity drive arm, Under the control of , the gravity ball can always stably and accurately perform unidirectional circulation movement, and collide with the gravity drive arm according to the set submersible piston starting angle to control the submersible piston to periodically circulate. When a gravity-driven circulation pipeline is adopted, when the piston cylinder rotates to the position corresponding to the submersible piston starting angle, the gravity ball starting platform is just in a horizontal state, and the gravity ball is located on the gravity ball starting platform. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform, and continues to move to the bottom of the circulation pipe body after colliding with the gravity drive arm. As the piston cylinder continues to rotate, the gravity ball reaches the bottom of the circulation pipe body and begins to enter another The auxiliary tube body on the side, as the piston cylinder continuously rotates, the gravity ball moves along the auxiliary tube body, and moves again to the bottom of the groove at the joint of the groove-shaped auxiliary tube body and the gravity ball starting platform. The gravity ball stabilizer controls and stabilizes the movement speed of the gravity ball from beginning to end. When the piston cylinder rotates to the position corresponding to the submerged piston starting angle, the gravity ball immediately starts to fall from the gravity ball starting platform again and hits the gravity drive arm. Under the control of the gravity-driven circulation pipeline, the gravity ball can always stably and accurately perform unidirectional circulation movement, and hit the gravity drive arm according to the set submerged piston starting angle, so as to control the submerged piston to cyclically move; (9) The submersible piston is automatically controlled to reciprocate periodically. On the inner walls of both ends of the piston cylinder, an integrated piston fixed angle control switch and a piston motion controller are respectively installed. When the submersible piston cooperates with the rotating disk of the engine to rotate clockwise, when the piston cylinder rotates to the position corresponding to the submersible piston starting angle below the horizontal plane on the right side of the engine center axis, the gravity ball starting platform of the piston fixed angle control switch located at the outer end of the piston cylinder is just in a horizontal state, and the gravity ball is located on the gravity ball starting platform. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform and The gravity driving arm is hit and pressed, and the gravity driving arm drives the transmission mechanism connected thereto to control the piston movement controller to release the submerged floating piston at the outer end of the piston cylinder, and the submerged floating piston floats upward rapidly. When the submerged floating piston moves to the locking position of the piston movement controller at the inner end of the piston cylinder, the piston movement controller immediately and automatically locks the submerged floating piston, causing the submerged floating piston to stop moving. As the piston cylinder continues to rotate, when the piston cylinder rotates to the position corresponding to the submerged floating piston starting angle above the horizontal plane on the left side of the engine central axis, the gravity ball starting platform of the piston fixed angle control switch at the inner end of the piston cylinder is just in a horizontal state, and the gravity ball starting platform of the piston fixed angle control switch at the inner end of the piston cylinder is just in a horizontal state. The ball is located on the gravity ball starting platform. As the piston cylinder rotates further, the gravity ball immediately starts to fall from the gravity ball starting platform and hits the gravity drive arm. The gravity drive arm drives the transmission mechanism connected to it to control the piston motion controller to release the submerged floating piston at the inner end of the piston cylinder. The submerged floating piston quickly floats upward. When the submerged floating piston moves to the locking position of the piston motion controller at the outer end of the piston cylinder, the piston motion controller immediately automatically locks the submerged floating piston to stop the submerged floating piston from moving. The submerged floating piston is locked and released cyclically and regularly, ensuring that the submerged floating piston has a stable and accurate cyclic reciprocating motion. The submersible pistons in all piston cylinders perform reciprocating motion in their respective cylinders in turn, so that the submersible pistons on the left and right sides of the vertical line of the engine's central axis produce torque differences and torque differences, thereby driving the piston cylinder together with the engine's rotating disk and the engine's central axis to rotate and output power to the outside. When the submersible pistons cooperatively drive the engine's rotating disk to rotate counterclockwise, the control method for the submersible pistons' periodic reciprocating motion is the same as the control method when the engine's rotating disk rotates clockwise.
