A conjugate double-cavity shuttle plate rotor engine mainly comprises a stator, a rotor and a shuttle plate. The stator consists of a stator cylinder and two end covers, the rotor consists of a cylindrical shaft and a coaxial cylinder with larger diameter and shorter length, and two shuttle plate grooves symmetrical to the shaft center are formed in the rotor; the shuttle plate is composed of two similar rectangular plates with the same shape and the same quality and is arranged in the shuttle plate groove of the stator. The two end covers are in mirror symmetry structure. Two conjugated cavities on two sides of the stator are formed on the inner surface of one stator cylinder, two inner surfaces which are mutually conjugated after the two stator end covers are installed, two side surfaces of one stator and the surface of the rotor shaft. An air inlet ignition cavity is designed and manufactured in one radial direction and the axial direction of the stator end cover, a fluid discharge cavity is designed and manufactured on the other side of the stator end cover, the spark plug ignites mixed gas sprayed into the air inlet cavity, and deflagration gas pushes the shuttle plate to further push the rotor to further drive the rotor shaft to rotate to output kinetic energy.
The present invention relates to a gas engine (internal combustion engine) and a fluid engine (similar to a water turbine). In particular to a space structure device which realizes the conversion of gas detonation into rotor kinetic energy output or the conversion of water potential energy (or other pressure fluid) into kinetic energy output by a conjugate double cavity, a rotor and a shuttle plate (or a shuttle pendulum) arranged on the rotor.
The traditional engine adopts the mode of a cylinder piston and a crankshaft connecting rod for transmission, because the piston is compressed to the bottom of the cylinder, when a spark plug ignites and explodes to do work, the piston connecting rod and the crankshaft are almost on the same straight line, the efficiency of useful work done by the thrust force generated by the explosion on the piston at the moment is almost zero by analyzing the principle of force, the engine can only do a small amount of useful work by depending on the angle generated by the crankshaft and the angle generated by the crankshaft and the inertia of an inertia flywheel, and along with the increase of the angle, when the included angle between the piston connecting rod and the crankshaft is a right angle, the kinetic energy generated by the explosion when oil-gas mixed gas in the cylinder is ignited by the spark plug can be completely acted on the power output of the engine to generate an extreme value of the useful work, but the analysis from the mechanical angle still has an opposite direction acting force along the power transmitted by the connecting rod, the friction force between the piston and the cylinder is increased to consume a part of energy, and in any case, the cylinder, the piston, the connecting rod and the crankshaft can not work in a right angle state for all the time, and certainly, the energy generated by the oil gas explosion in the cylinder can not be completely acted on the output of the engine to generate useful work, so that larger energy is consumed by the impact and the friction among the piston, the connecting rod and the crankshaft. The heat efficiency of the traditional cylinder piston engine which is mainstream all over the world at present is 30-38%, and the highest fuel utilization rate (heat efficiency) is only 41%. Moreover, because the angle between the traditional piston connecting rod and the crankshaft is constantly changed, the energy transfer efficiency is too low, the piston can only be made to be very large by increasing the kinetic energy of the piston, and meanwhile, the size and the weight are greatly increased by adding the inertia flywheel, so that the whole machine becomes heavy and embarrassed.
For a long time, the engine size and the number of parts are reduced, the running reliability of the engine is improved, the thermal efficiency of the engine is improved, and the production cost and the use cost are reduced, so that the engine is the target and pursuit of engine engineers. Although some progress is made in the above-mentioned aim, the components of the cylinder, piston, connecting rod and crankshaft are all indispensable and any revolutionary progress cannot be made due to the inherent principle and structural condition of the traditional engine. The wankel rotary engine (triangle rotary engine) breaks the monopoly of the traditional gas engine for many years, and has the advantages that compared with a four-stroke piston engine, the rotary engine has fewer moving parts. The birotor engine mainly has three moving parts: two rotors and an output shaft. Even the simplest four-cylinder piston engine has at least 40 moving parts including pistons, connecting rods, camshafts, valves, valve springs, rocker arms, timing belts, timing gears, and crankshafts, among others. The reduction of moving parts means a higher reliability of the rotary engine. This is why some aircraft manufacturers, including airbuses, prefer to use rotary engines rather than piston engines. It has a number of drawbacks: high manufacturing cost, difficult lubrication, high maintenance difficulty of maintenance cost, short service life, large pollution caused by insufficient combustion and the like.
The water turbine is mainly a mixed flow type (Francis water turbine), and the water energy conversion rate can reach 95 percent at most. Although mature, if the efficiency can be further improved to more than 96%, the method also contributes to the progress of the whole society.
SUMMERY OF THE UTILITY MODEL
The utility model aims to abandon traditional cylinder piston connecting rod crankshaft engine (hereinafter traditional engine) power production transmission mode and hydraulic turbine power production transmission mode thoroughly, use the utility model discloses a conjugate two-chamber shuttle board rotor internal combustion engine and conjugate two-chamber shuttle board rotor fluid engine (following unite two into one and be called for short conjugate two-chamber shuttle board rotor engine for short, or be called for short this engine) replace them, because the utility model discloses an engine or water transfer machine mainly comprise stator, rotor, three major assembly of shuttle board, therefore spare part quantity, volume and the weight of engine have been more than five than traditional engine less, just because of the structural component is minimum, complete machine reliability and life have very big improvement, manufacturing cost more can greatly reduced. Namely, the fuel thermal efficiency of the engine and the potential energy utilization rate of the hydraulic power generation water can be greatly improved, and the purposes of using a small amount of parts, extremely low space occupancy rate and production and use cost to achieve the utility model are achieved.
In order to achieve the above purpose, the utility model discloses technical scheme as follows:
the utility model discloses a conjugate two-chamber shuttle plate rotary engine mainly by three major parts: stator, shaft rotor, shuttle plate (or shuttle pendulum) and accessories. Other accessories are the same as conventional piston cylinder engine accessories such as intake valves, spark plugs, etc.
1. A stator: as shown in fig. 7, 9 and 10, the stator is composed of the stator housing of fig. 7 and two end covers of fig. 9 and 10. The middle of each end cover is provided with a central shaft hole 8 matched with a shaft rotor, each end cover is divided into two thickness areas, namely a thick area and a thin area, in the axial direction of the shaft hole, the two thickness areas are in smooth transition, transition surfaces are 3 and 9, and smooth transition curved surfaces 3 and 9 are in transition with a radial direction as a vertical line, so that the curved surfaces can be in sliding fit with the end surface 1 or 3 of a shuttle plate (shown in figure 11) (or a shuttle pendulum, which is briefly described below by replacing the shuttle plate with the shuttle plate or the shuttle pendulum) in movable fit, and meanwhile, the sealing can be effectively realized. An air inlet ignition deflagration cavity 7, an exhaust cavity 4 and an exhaust hole 5 are manufactured on each end cover transition surface 3 and 9. Fig. 9 a cavity is formed between the thin area faces 2, transition faces 3, 9 of the end caps of fig. 10 and the rotor end faces 3, 6 of the fig. 8 rotor, while the thick partial surfaces 6 of the end caps contact the rotor end faces 3, 6 of the fig. 8 rotor to implement a slip fit. The thick and thin parts of the two end covers are rotated by 180 degrees and then are installed in a matching way, so that a conjugate cavity is formed in the stator end cover, the rotor is installed, and due to the isolation of the rotor, the conjugate cavity between the two end covers of the stator is separated by the rotor to form a conjugate double-cavity structure. An air inlet valve (an air inlet one-way valve similar to a traditional engine) and an electric spark plug are respectively arranged at the positions of the stator corresponding to the air inlet ignition deflagration cavities of the two end covers, and an exhaust hole is respectively arranged in the exhaust cavity corresponding to the end cover.
2. Shaft rotor: referring to fig. 8, a rotor 3, 6 with a certain width is manufactured and installed outside a rotating shaft 2 with a diameter matched with the central hole of the end cover of the stator, and the rotor 3, 6 is respectively provided with an opening 4, 7 which is parallel to the axis and is called a shuttle plate opening or a shuttle plate groove at the position symmetrical to the rotor axis. The size of the gap of the opening is just required to achieve the size of the movable fit between the shuttle plate mentioned below.
3. A shuttle plate: referring to fig. 11, the plate (or pendulum) is designed to fit snugly into the two radially symmetrical shuttle slot (or gap) dimensions of the shaft rotor, and can be moved back and forth in the corresponding opening of the shaft rotor in the direction of the opening. This plate is called a shuttle plate.
4. The working principle of the engine is as follows: as shown in fig. 1-6, after one shuttle 12, 15 is installed in each of two radially symmetrical shuttle slot (or gap) of the shaft rotor 13, it is assembled into two end covers 4, 10 of the stator, and the shaft rotor 13 is rotated, and the two shuttle 12, 15 will do reciprocating motion along the axial direction in the conjugated dual cavities 2, 14 between the two end covers 4, 10 in addition to the synchronous rotation with the rotor 13. In turn, the shuttle plates 12 and 15 are pushed tangentially along the rotor 13 in one direction, and the shaft rotor 13 is pushed tangentially by the shuttle plates 12 and 15 to rotate in the force-bearing direction. The above-mentioned driving force can be that the gas-oil mixture deflagration gas ignited by sparking plug 7, 17 (equivalent to the gas-oil mixture deflagration gas ignited by sparking plug in piston cylinder does work) does work, at this moment, the function of the shuttle plate 12, 15 pushed by deflagration gas is equivalent to the piston function in traditional engine. It exerts the acting force directly and acts on the rotor 13 of the shaft rotor, and rotor 13 and rotor shaft 3 are the rigid body of relative fixation, therefore this thrust produced by above-mentioned shuttle plate 12, 15 is acted on the rotor shaft 3 directly and exported and do work directly, the utility model can be called as the conjugate double-chamber shuttle plate rotor internal combustion engine at this moment; if the ignition system is removed, the driving force is changed into other fluids, such as high-pressure water, high-pressure oil, high-pressure air and the like, and the engine can be called as a corresponding conjugate double-cavity shuttle plate rotor fluid engine. The engine is generally called a conjugate double-cavity shuttle plate rotor engine.
5. The working principle is described in detail: as in fig. 1-6, the first ignition does work: when fuel oil (or gas) and air mixed gas are input into 2 air inlets 5 and 18 of the assembled engine and are ignited and detonated by spark plugs 7 and 17, no matter which position of the two shuttle plates 12 and 15 in the stator, huge thrust can be applied to one or both of the two shuttle plates 12 and 15 to push the rotor 13 to rotate so as to drive the rotor shaft 3 to rotate and do work outwards. When the shuttle plates 12 and 15 pushed by the deflagration gas do work and the rotor 13 rotates to be close to 180 degrees, the shuttle plates 12 and 15 start to rotate to pass through exhaust holes (4 in figures 9 and 10) which are made in advance on the end cover of the stator, and the deflagration gas is exhausted from the corresponding exhaust holes 8 and 9. At this time, the other shuttle plate 15, 12 enters the preset deflagration position 6, 20 again, enters another round of ignition deflagration and enters the next working output process. And (3) performing ignition work for the second time and the nth time: an angle position indicating trigger matched with the stator 1 is designed and manufactured at a designated position on the rotor shaft 3 and used for accurately positioning the ignition time and angle, so that the rotor shuttle plates 12 and 15 are pushed by deflagration gas to rotate at the same position of each revolution to do work. Similarly, when the shuttle plates 12 and 15 pushed by the deflagration gas do work and the rotor rotates to close to 180 degrees, the shuttle plates 12 and 15 start to rotate to pass through exhaust holes (4 positions in fig. 9-10) which are pre-manufactured on the stator end covers 4 and 10, and the deflagration gas is exhausted from the exhaust holes. At this time, the other shuttle plate 15, 12 enters the preset deflagration position 6, 20 again, and the other round of ignition deflagration pushes the shuttle plate 15, 12 to enter the next working output process. The continuous circulation forms a three-step action work-doing cycle of 'air inlet/ignition deflagration-pushing shuttle plate to rotate around the shaft center to drive the rotating shaft to do work and output kinetic energy-exhaust' which is specific to the engine. The purpose of outputting the maximum and most stable kinetic energy of the engine can be realized by accurately setting the position of the optimal trigger at the angle on the rotating shaft. The engine has no energy loss except for the slight friction consumption of the sliding fit between the matching surface of the shuttle plate and the opening of the rotor, the sliding fit between the shuttle plate and the inner wall surface of the conjugate double-cavity of the end cover of the stator and the rolling fit of the bearing between the rotor shaft and the shaft hole of the stator. Therefore, the fuel utilization rate can be increased to more than 50-60 percent or even higher. This is a revolution of the history of oil and gas engines.

The specific implementation mode is as follows:
the technical solution of the present patent will be further described in detail with reference to specific examples.
Example 1: referring to fig. 1-12, the conjugate dual chamber shuttle plate rotor engine of the present invention is mainly divided into three major parts, the first part is a stator, which is a metal cylinder like the part marked with numeral 1 in fig. 7, and two additional stator end covers with the same structure and mirror symmetry are formed as fig. 9 and fig. 10; the second part is a rotor which is formed by adding two shuttle plate openings (shuttle plate grooves) on a shaft, such as the shaft marked with the number 2 in fig. 8, on the rotor, and two remaining parts of the rotor after the rotor is opened with the numbers 4 and 7 are marked with the numbers 3 and 6 in fig. 8; the third part is two pieces of the shuttle plate shown in fig. 11. Firstly, the stator end cover in fig. 9 is installed at the left end of the stator shown in fig. 7, then two shuttle plates are installed in the corresponding openings 4 and 7 on the rotor shaft shown in fig. 8 as shown in fig. 12, then the assembly sub-component in fig. 12 is assembled in the stator with the left end cover just installed, finally the stator right end cover in fig. 10 is installed at the right end of the assembly body, and the total assembly body of the invention shown in fig. 1 and fig. 3 is obtained. As for the accessories such as the air inlet component, the electric spark plug, the air outlet and the like in the general assembly body, the drawing is expressed only for the purpose of expressing the principle of the utility model, and the drawing and the expression are also realized because of the relationship. The structure principle and the working principle of the conjugate double-cavity shuttle plate rotor engine are as follows: in fig. 1-6, the stator end cover 4 and the end cover 10 mounted in the stator 1, each having a thickness region and a transition region between the thickness regions, as shown in fig. 9 and 10, in their two transition regions 3 and 9, respectively, there are an inlet cavity 7 and an outlet cavity 4 and an outlet hole 5, the inlet cavity 7 of the end cover corresponding to the inlet openings 2 and 6 in the stator housing shown in fig. 7, and the spark plug mounting positions 5 and 9, the outlet cavity 4 and the outlet hole 5 of the end cover corresponding to the outlet holes 7 and 3 in the stator housing shown in fig. 7, while the smaller end face 6 of the thicker portion of the stator end cover in fig. 9-10, corresponding to 3 and 6 in one of the two end faces of the rotor shown in fig. 8, respectively, is attached to the other face, so that the thin face 2 of the stator end cover in fig. 9 and 10 together with the two transition bevels 3 and 9 are attached to the two end faces 3 (fig. 8) and 5 (fig. 12) of the rotor, in addition, 2 conjugated cavities 2 and 14 which are axially symmetrical at 180 degrees are formed between the axial surface 1 of fig. 12 and the inner cylindrical surface 1 of fig. 7, and are separated by the shuttle plates 12 and 15, and the left and right conjugated cavities 2, 6 or 20, 14 separated by the two shuttle plates are always partially in the air inlet area and partially in the air outlet area. Therefore, no matter where the shuttle plates 12 and 15 are located, the first air intake ignition can push the shuttle plates to further push the rotor shaft to rotate to do work and output kinetic energy. While the length of the shuttle plates 12 and 15 is the width of the stator 13 plus the distance from the inside of the thinnest portion of the stator end cap 4 or 10, e.g., surface 2 of fig. 9-10, to the left (or right) surface of the rotor (i.e., to the 3/6 surface of fig. 8 or 5 surface of fig. 12), this length of the shuttle plate is also the distance between the transition radial slices of the two stator end caps 4 and 10 seen in fig. 1. In this way, regardless of the angle to which rotor 13 is turned, shuttles 12, 15 always contact and seal the chambers 2 and 6 separated by the two end caps in the conjugate double chamber, as shown in fig. 1 and 5. The utility model discloses the operation principle describes: when observing fig. 1-6, people control the air inlet nozzles 5 and 18 to inject the air-fuel mixture into the corresponding air inlet cavities 6 and 20 made of the left end cover and the right end cover and ignite with the electric spark plugs 7 and 17, the explosion gas at the moment expands rapidly in the cavities 6 and 20, pushes the shuttle plates with the numbers 12 and 15 to push the rotor with the number 13 to move to the direction along the stress direction of the shuttle plates, namely the tangential direction of the tangent circle vertical to the axial direction of the shaft rotor 13, and drives the rotor shaft 3 to do the same-direction circular motion. That is, the rotor shaft 3 is simultaneously subjected to the pushing rotation work of the opposite symmetrical thrust of the shuttle plates 12 and 15, and outputs power (the rotation direction is clockwise rotation in fig. 5, and counterclockwise rotation in fig. 6, and actually the two thrust forces are opposite on the tangent circle of the rotor, but the rotation directions of the pushing rotors are the same). In the process, the shuttles 12 and 15 are limited and influenced by the conjugate change of the inner curved surfaces (surfaces 2, 3, 6 and 9 in fig. 9 and 10) of the stator end covers 4 and 10 along with the rotation of the rotating shaft, and move left and right relative to the axial direction of the stator, so that the areas of deflagration thrust surfaces, which are received by the shuttles 12 and 15, are changed, maintained and reduced, and the outgoing power is increased, extremum and attenuated. However, because the change of kinetic energy in the three stages is relatively small and the time alternation is very rapid, two changes progress exist in each rotation of the rotor, so statistically, the three-stage dynamic energy output device can output a relatively stable power average peak value for people to use. If a plurality of rotors 13 are manufactured on the same shaft, a corresponding number of shuttle plates and a plurality of groups of stator end covers 4 and 10 are installed, and each group of end covers rotate in the axial direction to designate the installation angle which is accurately calculated, a multi-double-cavity conjugate rotor engine (corresponding to a multi-cylinder engine unit of a traditional engine) is formed, the volume is only slightly axially lengthened, and the volume is simple and can be ignored compared with the huge volume of the traditional multi-cylinder engine. Therefore, the output power is more stable and stronger.
Example 2: the present invention provides a conjugate dual chamber shuttle plate rotary engine, as shown in fig. 1-12, if the spark plugs 7, 17 on the stator 1 are removed and the mounting holes 5, 9 (fig. 7) are removed, a fluid engine is formed. The original positions of the air inlet nozzles 5 and 8 are changed into fluid inlets for inputting fluid, such as high-pressure air, high-pressure hydraulic oil, high-pressure water (including river water with drop potential) and the like, so that the shuttle plates 12 and 15 can be pushed to drive the rotor 13 to further drive the rotor shaft 3 to rotate to do work and output kinetic energy. Can be used for replacing various fluids such as a water turbine and the like to convert kinetic energy and the like.
Example 3: the conjugate double-cavity shuttle plate rotor engine of the utility model can deform the shuttle plate to be a shuttle pendulum, taking a figure 1 and a figure 3 as an example, 12 and 15 shuttle plates are removed and are changed into two shuttle pendulums, the shuttle pendulum is composed of a large cylindrical surface and a small cylindrical surface, the middle of the cylindrical surfaces are tangentially connected by two transition planes or curved surfaces, the small cylindrical surface is in front of the rotating direction of the rotating shaft of the shaft rotor, the large cylindrical surface is behind the rotating direction of the rotating shaft of the shaft rotor, the axes of the two cylindrical surfaces point to the axis of the rotating shaft of the shaft rotor, the large cylindrical surface can swing back and forth left and right by the axis of the small cylindrical surface, when swinging to the inner surface of the left end cover is contacted, the right side of the cylindrical surface of the large cylindrical surface is just level with the right side of the rotor, otherwise, the shuttle pendulum also takes the small shuttle pendulum cylinder as the center, the intersecting edge of the left surface of the cylindrical surface and the transition plane or the curved surface is just flush with the left surface of the rotor, so that the large cylindrical surface of the shuttle pendulum can have the same function as the shuttle plate in the embodiment 1 when the rotor rotates to any angle, and the large cylindrical surface swings to the inner part of the conjugate cavity to have the same effect as the shuttle plate; meanwhile, the opening on the rotor is also made into a structure and a shape matched with the shuttle pendulum.
