[0058] The present invention provides a multi-piston-driven vortex expansion output device. To make the objectives, technical solutions, and effects of the present invention clearer and more definite, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0059] The present invention is described in detail below with reference to the accompanying drawings:

[0060] Referring to Figure 1 , this embodiment provides a multi-piston-driven vortex expansion output device, which includes a power output and air intake mechanism 1, a primary gas storage tank 2, a speed change mechanism 3, a cam multi-piston compression mechanism 4, a heat exchanger 5, a secondary gas storage tank 6, and a vortex expansion output mechanism 7. The above-mentioned power output and air intake mechanism 1, speed change mechanism 3, and cam multi-piston compression mechanism 4 are coaxially arranged from top to bottom. The primary gas storage tank 2 is arranged between the power output and air intake mechanism 1 and the speed change mechanism 3, and the primary gas storage tank 2 is connected to the intake end of the cam multi-piston compression mechanism 4 through a pipeline.

[0061] The above-mentioned power output and air intake mechanism 1 is used to absorb gas and store the gas in the primary gas storage tank 2, and at the same time provide power for the cam multi-piston compression mechanism 4 to compress the gas entering the cam multi-piston compression mechanism 4 from the primary gas storage tank 2 to obtain high-pressure gas.

[0062] The outlet end of the above-mentioned cam multi-piston compression mechanism 4 is connected to the inlet end of the secondary gas storage tank 6 through the heat exchanger 5. The outlet end of the secondary gas storage tank 6 is connected to the vortex expansion output mechanism 7 through a pipeline. The above-mentioned heat exchanger 5 is connected to the industrial waste heat discharge end, that is, the industrial waste heat can heat the high-pressure gas compressed by the cam multi-piston compression mechanism 4 to form high-temperature and high-pressure gas and store it in the secondary gas storage tank 6. Then, the high-temperature and high-pressure gas enters the vortex expansion output mechanism 7 from the secondary gas storage tank 6, and the thermal energy is converted into mechanical energy for output.

[0063] Specifically, referring to Figures 2-4 , the above-mentioned power output and air intake mechanism 1 includes a power output component 11 and an air intake component 12, and the air intake component 12 is connected to the primary gas storage tank 2 and can suck gas into the primary gas storage tank 2. The power output component 11 is connected to the cam multi-piston compression mechanism 4 through the speed change mechanism 3 and can provide power for the cam multi-piston compression mechanism 4 to compress gas.

[0064] Among them, the above-mentioned power output component 11 includes a sealed cavity 111 and a servo motor 112 fixedly installed above the sealed cavity 111 and capable of forward and reverse rotation. The output end of the servo motor 112 is provided with a power output shaft 113, and a horizontal bevel gear 114 is fixedly arranged on the power output shaft 113. On both sides of the power output shaft 113, there are vertical bevel gears 115 meshing with the horizontal bevel gear 114. Both the horizontal bevel gear 114 and the vertical bevel gears 115 are arranged in the sealed cavity 111 and located in the middle of the sealed cavity 111, that is, in the middle sealed chamber of the following sealed cavity;

[0065] There are 2 groups of the above-mentioned air suction components 12, which are respectively located on both sides of the power output component 11. Each group of air suction components 12 includes a filter suction head 121 arranged above the sealed cavity 111 and on the side of the servo motor 112. Between the filter suction head 121 of each group of air suction components and the sealed cavity, and between the sealed cavity 111 and the first-stage gas storage tank 2, they are connected through pipelines; in addition, each group of air suction components 12 also includes an air suction pump arranged inside the sealed cavity 111 and on the side of the sealed cavity. The above-mentioned air suction pump is connected to the vertical bevel gear 115 on the same side through a horizontal connecting shaft. Specifically, the above-mentioned air suction pump includes an air suction pump drive gear 122 key-connected to the horizontal connecting shaft, an air suction pump cam structure 123 meshing and driving with the air suction pump drive gear, an air suction pump cylinder barrel 124, and an air suction pump piston 125 arranged inside the air suction pump cylinder barrel. The other end of the above-mentioned air suction pump piston 125 is connected to the air suction pump cam structure 123; in addition, the above-mentioned air suction pump cylinder barrel 124 is fixedly arranged at the inner bottom of the sealed cavity, and on one side of the above-mentioned air suction pump cylinder barrel 124, there is an air suction pump cylinder air inlet 126 which is communicated with the sealed cavity. One end of the above-mentioned air suction pump cylinder barrel 124 close to the first-stage gas storage tank is provided with an air suction pump cylinder air outlet and is communicated with the first-stage gas storage tank through a pipeline. And one-way valves are arranged in both the air suction pump cylinder air inlet and the air suction pump cylinder air outlet to control the gas inlet and outlet directions; in addition, the left and right sides of the above-mentioned sealed cavity 111 are separated, including a left sealed chamber, a middle sealed chamber and a right sealed chamber. The air suction pumps of the 2 groups of air suction components are respectively arranged in the left sealed chamber and the right sealed chamber.

[0066] In the above-mentioned power output air suction mechanism, when the servo motor rotates forward and backward, it can drive the air suction pump drive gear of the air suction component to rotate through the power output shaft, the horizontal bevel gear and the vertical bevel gear, so as to drive the air suction pump piston to move up and down along the air suction pump cylinder barrel through the air suction pump cam structure to realize the air suction and exhaust processes, that is, to suck the gas from the filter suction head through the sealed cavity, the air suction pump cylinder air inlet and the air suction pump cylinder air outlet into the first-stage gas storage tank; and at the same time when sucking the gas, the filter suction head can filter the gas to reduce the content of impurity particles in the sucked gas.

[0067] In addition, when the above-mentioned suction pump operates, since the gas first enters the sealed cavity through the filter suction head and then enters the suction pump cylinder through the air inlet of the suction pump cylinder, an air flow is formed around the suction pump cylinder, which can play a role in dissipating heat and cooling the cylinder pump, ensuring that the cylinder pump can work continuously for a long time. To further improve the heat dissipation effect, the materials of the suction pump cylinder and the sealed cavity can be selected as heat-dissipating materials.

[0068] Specifically, referring to Figure 5 , the above-mentioned speed-changing mechanism 3 includes a telescopic mechanism 31 and a speed-changing fixed frame 32. Among them, one end of the telescopic mechanism 31 is connected to the power output shaft 113, and the other end of the telescopic mechanism 31 is coaxially connected to a first power transmission shaft 34 through a first clutch 33; the telescopic mechanism 31 includes a telescopic shaft 3101 and a telescopic cylinder, the telescopic cylinder is coaxially and fixedly installed inside the telescopic shaft 3101, one end of the telescopic shaft 3101 is connected to the power output shaft 113, and one end of the piston rod of the telescopic cylinder is connected to the first power transmission shaft 34;

[0069] A central sun gear 35 is connected to the above-mentioned first power transmission shaft 34 by a key. On both sides of the central sun gear 35, there are first planetary gears 36 meshing externally. And below the central sun gear 35 and located on the outer ring surrounding the central sun gear 35, there is a first internal gear ring 37 that can mesh with or disengage from the lower part of the central sun gear (when the telescopic mechanism extends, the central sun gear can mesh with the first internal gear ring, and when the telescopic mechanism retracts, the central sun gear disengages from the first internal gear ring). Above the central sun gear 35 and surrounding the outer rings of the two first planetary gears 36, there is a second internal gear ring 38 that meshes with the two first planetary gears 36. The above-mentioned second internal gear ring 38 is fixedly connected to the first internal gear ring 36 through a connecting arm; and above each first planetary gear 36, there is a second clutch 39 coaxially arranged, and at the top of the second clutch 39, there is a second planetary gear 310 coaxially arranged;

[0070] In addition, at one end of the above-mentioned first internal gear ring 37 away from the central sun gear 35, there is a third clutch 311, at the other end of the third clutch 311, there is a second power transmission shaft 312, and at the end of the second power transmission shaft 312 away from the third clutch 311, there is a third planetary gear 313 connected by a key. On both sides of the third planetary gear 313, there are fourth planetary gears 314 meshing externally, and the centers of the fourth planetary gears 314 are all penetrated by a third power transmission shaft 315;

[0071] There is a fifth planetary gear 316 meshing externally with the second planetary gear 310, and there is a sixth planetary gear 317 meshing externally with the fourth planetary gear 314. The fifth planetary gear 316 and the sixth planetary gear 317 are connected by a fourth power transmission shaft 318;

[0072] In addition, the above-mentioned variable-speed fixing frame 32 is cylindrical and internally provided with several fixing layers. The above-mentioned first power transmission shaft 34, second power transmission shaft 312, third power transmission shaft 315, fourth power transmission shaft 318, and first clutch 33, second clutch 39, and third clutch 311 are all fixed on the variable-speed fixing frame 32 through bearings.

[0073] Referring to Figure 6 and Figure 7 , the above-mentioned first, second, and third clutches each include a first clutch connection end 319, a second clutch connection end 320, a slider 321, and a scroll spring 322. The first clutch connection end 319 and the second clutch connection end 320 are butted to form a cylindrical body, and the slider 321 and the scroll spring 322 are arranged inside the cylindrical body; and several wedge-shaped protrusions are arranged on the side of the first clutch connection end 319 close to the slider at intervals. The slider 321 is a hollow cylinder and several arc-shaped protrusions are arranged on the outer ring of the slider. The arc-shaped protrusions of the slider 321 can be clamped or loosened with the wedge-shaped protrusions of the first clutch connection end 319. A slide rod that can extend into the central hole of the slider is arranged on the side of the second clutch connection end 320 close to the slider; in addition, several scroll springs 322 are arranged, and the several scroll springs 322 are arranged on the side of the slider 321 close to the second clutch connection end 320, and the several scroll springs 322 are evenly arranged around the central hole of the slider.

[0074] In addition, the installation directions of the first clutch and the third clutch are the same, and the installation directions of the first clutch and the second clutch are opposite.

[0075] In the above speed-changing mechanism, when the servo motor rotates forward and the telescopic mechanism is in the retracted state, the first clutch connects the telescopic mechanism to the first power transmission shaft, the central sun gear rotates, the central sun gear meshes with the first planet gear externally to transmit torque, and at the same time the first planet gear meshes with the second internal gear ring internally. At this time, the second clutch connects the second planet gear to the first planet gear, and the third clutch disconnects the first internal gear ring from the second power transmission shaft. Furthermore, the second planet gear drives the fifth planet gear, the fourth power transmission shaft and the sixth planet gear to rotate to transmit the torque to the second power transmission shaft, thereby providing power for the cam multi-piston compression mechanism; when the servo motor rotates forward and the telescopic mechanism is in the extended state, the first clutch connects the telescopic mechanism to the first power transmission shaft, the central sun gear rotates, and the central sun gear meshes with the first internal gear. At this time, the second clutch disconnects the second planet gear from the first planet gear, and the third clutch connects the first internal gear ring to the second power transmission shaft. Furthermore, the central sun gear meshes with the first internal gear to transmit the torque to the second power transmission shaft, thereby providing power for the cam multi-piston compression mechanism; when the servo motor rotates in reverse, the first clutch disconnects the telescopic mechanism from the first power transmission shaft, and the speed-changing mechanism does not output torque. Through the above speed-changing mechanism, different transmission speed adjustments can be achieved. In addition, when the servo motor rotates in reverse, since the speed-changing mechanism does not output torque, only the power output air intake mechanism absorbs gas and stores it in the first-stage gas storage tank at this time, and the cam multi-piston compression mechanism does not compress either.

[0076] Specifically, referring to Figure 8 and Figure 9 , the above-mentioned cam multi-piston compression mechanism 4 includes a first piston cylinder 41, a second piston cylinder 42 and a cam assembly located between the first and second piston cylinders. The cam assembly can compress the gas in the first and second piston cylinders; and the intake ends of the first piston cylinder 41 and the second piston cylinder 42 are connected to the first-stage gas storage tank 2 through a plurality of intake pipes 8. The bottom of the first piston cylinder 41 and the top of the second piston cylinder 42 are connected through a plurality of first-stage exhaust pipes 43. The bottom of the second piston cylinder 42 is connected to the heat exchanger 5 through a plurality of second-stage exhaust pipes. The high-pressure gas in the first and second piston cylinders finally converges into the heat exchanger 5 through the second-stage exhaust pipes for heat exchange. And one-way valves are provided on the above-mentioned intake pipes, first-stage exhaust pipes and second-stage exhaust pipes. The above-mentioned heat exchanger 5 specifically adopts a shell-and-tube heat exchanger. There is no direct mixing between the industrial waste heat and the high-pressure gas, and the high-pressure gas pressure will not be reduced. Under the action of the temperature difference, the heat of the industrial waste heat exchanges heat with the low-temperature high-pressure gas generated by the cam multi-piston compression mechanism, thereby outputting high-temperature high-pressure gas.

[0077] The above-mentioned cam assembly includes a multi-piston power input shaft 44 connected to the second power transmission shaft 312, a track cam 45 key-connected to the multi-piston power input shaft 44, and a plurality of piston connecting rods 46 arranged around the outer ring of the track cam. Cam compression pistons 47 are provided at both ends of each piston connecting rod, and the cam compression pistons at both ends of each piston connecting rod 46 respectively extend into the first piston cylinder 41 and the second piston cylinder 42;

[0078] In addition, a piston fixing frame 48 with a plurality of fixed support brackets is also arranged around the outer ring of the track cam 45, and the middle part of each piston connecting rod 46 is connected to the corresponding fixed support bracket of the piston fixing frame 48;

[0079] A wavy cam track 49 is provided on the outer ring of the above-mentioned track cam 45. A track sphere facing the track cam 45 and tangent to the cam track is provided at the connecting part of each piston connecting rod 46 and the fixed support bracket, and the track sphere can move along the wavy cam track 49.

[0080] In the above-mentioned cam multi-piston compression mechanism, when the second power transmission shaft transmits power to the multi-piston power input shaft, the multi-piston power input shaft can drive the track cam to rotate, and then a plurality of piston connecting rods arranged around the outer ring of the track cam move up and down along the cam track, thereby driving the pistons to move up and down to compress the gas in the first and second piston cylinders to obtain high-pressure gas. Then, the high-pressure gas is discharged to the heat exchanger through the secondary exhaust pipe of the cam multi-piston compression mechanism, and after heat exchange, high-temperature and high-pressure gas is obtained and stored in the secondary gas storage tank. Specifically, referring to Figures 10-11 The above-mentioned scroll expansion output mechanism 7 includes a scroll housing, and the scroll housing includes an upper scroll housing 71 and a lower scroll housing 72 separated by a partition.

[0081] Among them, a stationary scroll plate 73 is fixedly arranged at the bottom of the above-mentioned lower scroll housing 72, and a scroll air inlet 74 communicated with the air outlet end of the secondary gas storage tank 6 is arranged at the bottom of the stationary scroll plate 73;

[0082] A moving scroll plate 75 matched with the stationary scroll plate is arranged in the middle and lower part of the lower scroll housing 72 and above the stationary scroll plate 73. The scroll teeth of the stationary scroll plate 73 are internally engaged with the scroll teeth of the moving scroll plate 75; and a notch is formed at the bottom of the moving scroll plate 75 and a gasket is arranged in the notch;

[0083] An annular special-shaped ball fixing frame 76 is arranged in the upper middle part of the lower vortex housing 72 and above the moving vortex disk 75. A number of holes are arranged around the circumference of the special-shaped ball fixing frame 76, and each hole is installed with a special-shaped ball 77. The inner diameter of the hole is larger than the ball diameter of the special-shaped ball. And a plurality of support springs are arranged inside each special-shaped ball 77. Elastic gaskets are arranged above and below each special-shaped ball 77. The elastic gasket below the special-shaped ball is embedded in the top of the moving vortex disk, and the elastic gasket above the special-shaped ball is embedded in the bottom of the partition between the upper and lower vortex housings.

[0084] In addition, a crankshaft 78 is arranged at the center of the top of the above-mentioned moving vortex disk 75. The crankshaft 78 passes through the center of the special-shaped ball fixing frame 76 and extends out of the vortex housing. And a balance weight 715 is installed on one side of the above-mentioned crankshaft, which can reduce the centrifugal force of the crankshaft rotation.

[0085] Four coils 79, four permanent magnets 710 and four Hall elements 711 are arranged in the upper middle part of the above-mentioned upper vortex housing 71. And the four coils, permanent magnets and Hall elements are symmetrically distributed about the crankshaft. In addition, an annular strong magnet 712 is arranged on the top surface of the above-mentioned moving vortex disk, and the strong magnet 712 is arranged inside the inner circle of the special-shaped ball fixing frame 76.

[0086] In addition, a vortex exhaust port 713 is further arranged at the bottom of the above-mentioned lower vortex housing. The vortex exhaust port 713 is connected to one of the intake pipes 8 through a return pipeline 714 and is communicated with the intake end of the cam multi-piston compression mechanism 4 through the intake pipe 8. That is, the gas at the intake end of the cam multi-piston compression mechanism not only comes from the gas inhaled into the first-stage gas storage tank by the power output suction mechanism, but also comes from the high-pressure gas discharged through the return pipeline from the vortex exhaust port in the vortex expansion output mechanism. Of course, the gas inhaled by the power output suction mechanism is the main source.

[0087] In the above-mentioned vortex expansion output mechanism, when the high-temperature and high-pressure gas enters the closed cavity formed by the meshing of the stationary vortex disk and the moving vortex disk from the vortex intake port, it can push the moving vortex disk to translate and rotate, and the crankshaft connected to the moving vortex disk outputs torque, thereby converting the energy of the high-temperature and high-pressure gas into mechanical energy. When the pressure of the incoming high-temperature and high-pressure gas increases, the coil current can be increased by controlling the Hall element, so that the repulsive force between the permanent magnet and the strong magnet increases, and the back pressure of the moving vortex disk can be increased. At this time, the special-shaped ball can undergo a small deformation but does not change the translational rotation of the moving vortex disk, thereby reducing the radial leakage, and vice versa.

[0088] In addition, in this embodiment, when connecting the secondary gas storage tank 6 to the scroll expansion output mechanism 7, the connection is made sequentially through an air filter pressure reducing valve 9 and a high-temperature and high-pressure two-way valve 10, and a pressure gauge is connected to the air filter pressure reducing valve 9; the high-temperature and high-pressure gas obtained by compression through the cam multi-piston compression mechanism 4 and heat exchange in the heat exchanger 5 can be stored in the secondary gas storage tank 6. When the pressure gauge monitors that the gas pressure reaches the set value, the high-temperature and high-pressure two-way valve opens to discharge the high-temperature and high-pressure gas into the scroll expansion output mechanism, and the scroll expansion output mechanism converts the energy of the high-temperature and high-pressure gas into mechanical energy for output.

[0090] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
