Description

Technical Field

[0001] The present invention relates to an engine, and particularly to a rotary high-pressure gas power engine that utilizes the pressure of high-pressure steam or gas as power.

Background Art

[0002] Currently, engines play an extremely important role in automobiles, industrial machinery, and other fields that require power. Generally, conventional engines, whether internal combustion engines or external combustion engines, achieve a complete power cycle by performing a plurality of strokes through the engagement between members such as cylinders, pistons, crankshafts, and valves.

[0003] The invention of the steam engine in the 18th century initiated the First Industrial Revolution and led mankind into the era of mechanical production. This demonstrated the importance of the steam engine for human civilization. However, since the motion mechanism of conventional steam engines is reciprocating motion, not only is the structure and manufacture of the engine extremely complex, but also the heat conversion efficiency of the engine's work is significantly reduced. Therefore, conventional steam engines have been abolished.

[0004] Although conventional steam engines have been abolished, due to the characteristic that water expands 1,700 times in volume when vaporized, steam power is still used in industries such as nuclear power generation, thermal power generation, and geothermal power generation, such as converting thermal energy into electrical energy using steam turbines. Since steam turbines utilize steam in an open manner, they cannot effectively utilize the pressure generated by the large expansion of steam, resulting in a very low thermal efficiency.

[0005] Currently, the AI era has arrived and a large amount of power sources are required. Therefore, it has been found that the most important issue at present is how to provide an advanced steam power generation device with a simple structure and a significantly improved thermal efficiency.

[0009] Possible embodiments of the present invention will be described below with reference to examples, but these examples are not intended to limit the scope of protection of the present invention.

[0010] Referring to Figures 1 to 11, an embodiment of the present invention is shown, in which the rotary high-pressure gas-powered engine of the present invention includes a stator mechanism 10, a rotor 20, a spindle 30, a plurality of pistons 40, and a plurality of air covers 50.

[0011] The stator mechanism 10 includes two stators 11A and 11B and two stator oil seals 17, each of which includes one guide annular groove 111 and two stator slots 16 extending annularly inside and outside the guide annular groove 111, the guide annular grooves 111 of the two stators 11A and 11B forming a rail 12 corresponding to the axial direction, the two stator oil seals 17 fitted between the stator slots 16 of the two stators 11A and 11B, and a bearing 18 fitted in the center of each of the two stators 11A and 11B. The rotor 20 is rotatably mounted between the two stators 11A and 11B and includes a plurality of cylinders 21 and a plurality of ventilation holes 22, with a plurality of grooved holes 212 penetrating the cylinder wall 211 of each cylinder 21, and the plurality of ventilation holes 22 opening onto the outer circumferential surface of the rotor 20 and communicating with the interior of each of the plurality of cylinders 21. The spindle 30 is provided with a plurality of axial ventilation slots 31 corresponding to the cylinders 21, and the spindle 30 is inserted through the stator mechanism 10 and the rotor 20 and moves in synchronization with the rotor 20, preferably the rotor 20 is provided with rotor slots 231, and the spindle 30 is provided with axial projections 32 protruding from the spindle, the axial projections 32 being inserted into the rotor slots 231 and rotating the rotor 20 in synchronization with the spindle 30. Each of the multiple pistons 40 has a piston oil seal 44 circumferentially provided at its upper and lower ends. Each of the multiple pistons 40 is housed in the multiple cylinders 21 and is provided with a piston shaft rod 41 that protrudes axially from the multiple grooves 212 and moves along the rail 12. Each of the pistons 40 and each of the piston oil seals 44 moves in an engine oil passage system formed by the space between the cylinder walls 211 of each cylinder 21, the space between the two stator oil seals 17 of the stator mechanism 10, and the multiple grooves 212 communicating with each other.Each of the multiple air covers 50 is mounted on the stator mechanism 10 so as to be radially movable and elastically recoverable, and covers the outer circumferential surface of the rotor 20, with a gas injection space S formed between each air cover 50 and the outer circumferential surface of the rotor 20, and each air cover 50 includes a gas passage 51 for transporting high-pressure gas that communicates with the gas injection space S. When the gas injection space S communicates with the multiple vents 22, the high-pressure gas is introduced into the gas injection space S via the gas passage 51 of each air cover 50, enters the multiple cylinders 21 through the multiple vents 22, pushes the multiple pistons 40 radially inward, and rotates the rotor 20 relative to the stator mechanism 10. If the gas injection space S is not in communication with the plurality of vent holes 22, the piston shaft rods 41 of the plurality of pistons 40 move along the rail 12, moving the plurality of pistons 40 radially outward and discharging the high-pressure gas inside the plurality of cylinders 21 through the plurality of vent holes 22.

[0012] In this embodiment, when liquid water is heated to 100°C and turns into steam, its volume expands by approximately 1,700 times. Utilizing this property as a power source yields the most efficient engine. Each air cover 50 is elastically resilient to cover the outer surface of the rotor 20, minimizing steam release. Furthermore, the pressure of the steam inside each air cover 50 pushes it outward, significantly reducing frictional resistance between each air cover 50 and the rotor 20 during operation. As a result, frictional energy loss between mechanical parts becomes extremely low. Therefore, this rotary high-pressure gas-powered engine provides industry with a highly effective and thermally efficient power source.

[0013] The stator mechanism 10 further includes a plurality of bolts 13 and a plurality of bolt sleeves 14. These two stators 11A and 11B each further include a plurality of through holes 112. The plurality of bolt sleeves 14 abut between these two stators 11A and 11B. The plurality of bolts 13 pass through the plurality of through holes 112 of these two stators 11A and 11B and the plurality of bolt sleeves 14, whereby the distance between these two stators 11 is made constant. Also, when the plurality of bolts 13 pass through the plurality of through holes 112 of these two stators 11A and 11B, the guide annular grooves 111 of these two stators 11 accurately correspond to form a rail, and play a role in accurately restricting the plurality of air covers 50.

[0014] The rotor 20 includes a rotor body 23 and an annular member 24 provided around the rotor body 23. The rotor body 23 includes the plurality of cylinders 21. The annular member 24 includes the plurality of vent holes 22 and corresponds to a cylinder head. In such an engagement configuration, processing, manufacturing, and assembly are facilitated. Further, an annular slot 213 is provided at the outer edge of the top of the cylinder 21. A seal ring 214 is accommodated in the annular slot 213 between the rotor body 23 and the annular member 24. The seal ring 214 seals the gap between the rotor body 23 and the annular member 24, so that the gas in the power stroke of the cylinder 21 does not leak from the gap. Preferably, the annular member 24 includes a plurality of concave holes 241 distributed at intervals in the circumferential direction, and oil can be injected from the oil injection hole 54 of the air cover to the concave holes 241. The concave holes 241 have an oil storage function and ensure a sufficient lubrication effect between the air cover oil seals 52 on both sides of the bottom of the air cover 50 and the rotor 20. For example, on both sides of the annular member 24, the concave holes 241 (for example, small circular holes) are provided every 3 mm at the locations where they contact the plurality of air covers 50, and the depth of each concave hole 241 is 1 mm. However, the shape, interval, depth, etc. of the plurality of concave holes 241 may vary according to the design needs.

[0015] The stator 11B is provided with an oil supply hole 114, to which an oil supply pipe 116 opening upward is connected. Since the oil supply pipe 116 opens upward, lubricating oil is introduced into the engine by gravity. The oil supply hole 114 is provided between these two stator oil seals 17 and is used for injecting lubricating oil. The lubricating oil enters the cylinder 21 through the groove hole 212, then enters between the stator 11A and these two stator oil seals 17. The stator 11A is provided with an oil drain hole 115, to which an oil drain hole pipe 117 opening downward is connected. Finally, the lubricating oil flows into the rotary high-pressure gas-powered engine 1 through communicating with the oil drain hole pipe 117 via the oil drain hole 115 of the stator 11A. By sealing the engine oil passage system, sufficient lubricating oil is ensured to lubricate the moving parts of the rotary high-pressure gas-powered engine 1 during the operation of the engine.

[0016] In this embodiment, the rotary high-pressure gas-powered engine 1 further includes a plurality of air cover shaft rods 60 and a plurality of tension springs 70. Each of these two stators 11 includes a plurality of stator holes 113. Each of the plurality of air cover shaft rods 60 is inserted into the plurality of stator holes 113 so as to be movable in the radial direction. Each of the plurality of tension springs 70 is connected between the stator mechanism 10 and the plurality of air cover shaft rods 60. Specifically, both ends of each tension spring 70 are respectively hung on the air cover shaft rod 60 and the positioning hook member 15 of the stator mechanism 10. Thereby, when the high-pressure gas pressure decreases, in order to avoid insufficient air pressure, each air cover 50 tends to move closer to the outer peripheral surface of the rotor 20.

[0017] In this embodiment, each stator hole 113 extends radially over the stator mechanism 10. An air cover oil seal 52 is further provided around the end face of the annular recess of each air cover 50, and the air cover oil seal 52 contacts the outer circumferential surface of the rotor annular member 24. A portion of the air cover oil seal 52 is firmly fixed within the air cover slot 53 of the air cover 50 with an adhesive material (e.g., a strong adhesive), and the air cover 50 is pushed outward by the high-pressure steam inside the air cover 50, but each air cover shaft rod 60 is limited to the slightly longer space of the stator hole 113. Because the diameter of the stator hole 113 is larger than the outer diameter of the air cover shaft rod 60, the high-pressure steam cannot completely escape from the constraint of each air cover 50. Therefore, when friction occurs between the air cover 50 and the rotor during the operation of the rotary high-pressure gas-powered engine 1, the steam pressure is increased, forming an air cushion or air film between the air cover 50 and the annular member 24, resulting in extremely low frictional resistance.

[0018] Preferably, each air cover 50 includes at least one oiling hole 54 that opens facing the outer circumferential surface of the rotor annular member 24, and each piston 40 includes an annular recess 42 for oil storage. More specifically, each air cover 50 includes a plurality of oiling holes 54, which are located outside the air cover oil seal 52, and each oiling hole 54 is connected to an oil source via an oil pipe 56 by an oiling nozzle 55. As each piston 40 moves within the cylinder 21, oil is present in the annular recess 42 of each piston 40, and the large amount of oil allows for effective heat dissipation in addition to sufficient lubrication. Furthermore, the bottom of each piston 40 further includes a cavity 43, thus reducing weight.

[0019] As the recessed hole 241 of the annular member 24 passes through the opening of the oil injection hole 54, oil enters the recessed hole 241 of the annular member 24, thereby maintaining lubrication of the air cover oil seal 52 during operation, reducing frictional resistance and frictional wear. Because the size of the recessed hole 241 is small and the compressed air cover oil seal 52 expands to cover the recessed hole 241, oil leakage is avoided and the lubrication effect is well maintained over a long period of time.

[0020] In a preferred embodiment of the present invention, the rail 12 has four identical strokes within 360 degrees, so that the rotating spindle 30 can simultaneously receive the operating force from the four power strokes; however, the rail 12 may have two or three identical strokes (see Figures 12 and 13) or any other number of strokes within 360 degrees.

[0021] The operation of the rotary high-pressure gas-powered engine 1 is described below. When each of the air cover shaft rods 60 is at the power stroke initiation point C corresponding to the rail 12 radially upstream of the rotor 20, high-pressure gas begins to be transported to the air cover 50 at an advance point A prior to the power stroke initiation point C. At this time, the piston 40 is limited by the rail 12 and does not move. As the piston shaft rod 41 moves along the rail 12 until it corresponds to the power stroke initiation point C, and the piston shaft rod 41 begins to slide downward along the rail 12, each of the cylinders 21 is pushed by the high-pressure gas. Therefore, the stroke between the advance point A and the power stroke initiation point C is not considered a power stroke and only causes each of the cylinders 21 to be subjected to pressure early. When the plurality of vents 22 move until they correspond to the exhaust point B, the high-pressure gas in each of the cylinders 21 is discharged to the outside through the plurality of vents 22. In other words. When the vent holes 22 of the rotor 20 move to correspond to the stroke range of the forward point A, each cylinder 21 begins to receive pressure. When the vent holes 22 of the rotor 20 move to correspond to the power stroke start point C, the power stroke begins. When the vent holes 22 of the rotor 20 move to correspond to the exhaust point B, the exhaust stroke begins.

[0022] Furthermore, in the stage where the piston 40 slides downward along the rail 12, if the air pressure inside the air cover 50 is sufficient to push the piston 40, the piston shaft rod 41 slides downward along the inside 121 of the rail for the power stroke of the rail 12. If the air pressure inside the air cover 50 is insufficient to push the piston 40 downward (for example, engine stall), the piston shaft rod 41 moves along the outside 122 of the rail for the power stroke of the rail 12 due to the action of centrifugal force.

[0023] Furthermore, the ventilation slots 31 communicate with each cylinder 21, and when the engine is operating and the piston 40 moves downward along the radial direction of the engine, the air below the piston 40 is expelled through the ventilation slots 31. When the piston 40 moves upward along the radial direction of the engine, outside air enters each cylinder 21 through the ventilation slots 31.

[0024] Furthermore, in addition to being used as an industrial power source, the rotary high-pressure gas-powered engine 1 of the present invention can also be used to heat chilled water to high-temperature hot water using a solar water heater, or to supply non-corrosive water to a boiler through heat exchange using high-temperature hot spring water from geothermal sources. In this case, when the boiler is slightly heated and the hot water reaches 100°C, the hot water vaporizes and generates high-pressure steam. This high-pressure steam enters the air cover 50 via a gas transport pipe, operating the rotary high-pressure gas-powered engine 1 of the present invention to generate electricity, thus creating a very inexpensive power source. Moreover, since this rotary high-pressure gas-powered engine uses high-pressure gas in a sealed environment and can almost completely utilize the pressure generated by the large expansion of the high-pressure gas only within the sealed space, this high-pressure gas-powered engine is expected to have significantly improved thermal efficiency and is a promising means of solving the energy challenges facing humanity.
