Technical Field
[0001] This invention relates to the technical field of internal combustion engines and generators, and more particularly to an integrated rotary piston gas turbine generator set. Background Technology
[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system and a control system, driven by a water turbine, steam turbine, diesel engine, or other power machinery. It converts the energy generated by water flow, airflow, fuel combustion, or nuclear fission into mechanical energy, which is then transferred to a generator. The generator then converts this mechanical energy into electrical energy, which is output to electrical equipment. Existing generator sets for range-extended electric vehicles, electric agricultural machinery and tractors, fully electric boats, heavy-duty electric aircraft, and engineering sites without mains power are complex in structure, large in size and weight, and expensive, and urgently need to be upgraded or replaced.
[0003] In range-extended electric vehicles (REEVs), the range extender's operating speed and power are completely decoupled from the vehicle's overall speed, thus not being limited by vehicle speed. Automotive drive systems can be categorized into diesel engines, gasoline engines, electric motors, and hybrid systems. Common gasoline and diesel engines are reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement to output power. However, reciprocating piston internal combustion engines use a single type of fuel and suffer from problems such as large mass and significant space occupation during piston reciprocating motion.
[0004] An aircraft engine, also known as a flight engine, is a device that converts the thermal energy or other forms of energy of fuel into mechanical energy to provide power for aircraft such as airplanes and helicopters. It is a highly complex and precise thermodynamic machine that provides the power required for aircraft to fly. It has the advantage of being lightweight, but due to its low efficiency and high price, it is difficult to apply directly to electric vehicles.
[0005] In general, existing reciprocating piston engines used in automobiles, airplanes, ships, and tractors are relatively efficient and inexpensive, but their biggest drawback is their large size and heavy weight, limiting their application range. Aero engines (mostly used in aircraft, but also in ships and tanks) are essentially gas turbines. Compared to reciprocating piston engines, they lack pistons and other piston-like components, making them a type of rotary engine (turbomachinery). They can be made smaller and lighter for the same output power, but their disadvantages are lower efficiency and higher cost. At the same output power, reciprocating piston engines (generator sets) can achieve an efficiency of around 40%, while gas turbines (generator sets) struggle to reach 30%. Gas turbines weigh less than half that of reciprocating piston engines, and their price is about ten times that of reciprocating piston engines. Therefore, there is an urgent need for a high-efficiency, small-sized, lightweight, and low-cost generator set. Summary of the Invention

[0055] In addition to the above, the present invention also has the following embodiments:
[0056] In a further embodiment of the present invention, an integrated rotary piston gas turbine generator set is disclosed, which consists of three parts: a generator, an internal combustion engine, and a turbine.
[0057] In a further embodiment of the present invention, the integrated rotary piston gas turbine generator set is a whole. All fixed parts of the whole are defined as the stator part, which is a component of the integrated rotary piston gas turbine generator set. All rotatable parts of the whole are defined as the rotor part, which is a component fixed on a crankshaft.

The rotating piston is also known as the blade rotor body 405.
[0059] In a further embodiment of the present invention, which relates to the field of internal combustion engine and generator technology, the invention proposes a method where the combustion of gas or oil in a cylinder generates heat to drive a rotating piston rotor 405, which in turn drives a turbine rotor 5. The rotational force of the rotor 405 and the turbine rotor 5 drives a compression system to ensure the intake and pressure of the combustion chamber, and drives a coaxial generator to produce electricity. By replacing the reciprocating piston of the existing reciprocating piston internal combustion engine with a rotating piston and using the turbine rotor 5 for turbocharging, the mass and size of the engine are reduced. A rotating piston gas turbine generator set with the same power output has a volume of only about 1 / 3 to 1 / 2 that of an existing internal combustion engine generator set, and its efficiency is higher than that of a gas turbine generator set with the same power output. It has a simple structure, is easy to manufacture, inexpensive, reliable in operation, robust and durable, and has high operating efficiency, making it more suitable for high-speed operation.
[0060] In a further embodiment of the present invention, a rotary piston replaces the reciprocating piston of the existing reciprocating piston internal combustion engine, and a turbine rotor 5 is used for turbocharging. Compared with the existing internal combustion engine, the volume and mass of the rotary piston gas turbine generator set are halved, while the power generation efficiency is the same.
[0061] In a further embodiment of the present invention, the integrated rotary piston gas turbine generator set proposed in this patent generates heat by burning gas or oil in the cylinder to drive the blade rotor 405 to rotate, which in turn drives the turbine rotor 5 to rotate. The rotational force of the blade rotor 405 and the turbine rotor 5 drives the compression system to ensure the intake and pressure of the combustion chamber, and drives the coaxial generator to generate electricity. By replacing the reciprocating piston of the existing reciprocating piston internal combustion engine with a rotary piston and using the turbine rotor 5 for turbocharging, the mass is reduced while the engine size is reduced. The rotary piston gas turbine generator set with the same power is only about 1 / 3 to 1 / 2 the size of the existing internal combustion engine generator set, and the efficiency is higher than that of the gas turbine generator set with the same power. It has a simple structure, is easy to manufacture, is inexpensive, reliable in operation, robust and durable, and has high operating efficiency, making it more suitable for high-speed operation.
[0062] In a further embodiment of the present invention, based on the cycloidal curve equation, a series of rotary piston propulsion systems with different numbers of combustion chambers are given, such as... Figures 13 to 16 As shown, compared to existing internal combustion engine units, this design increases the pressure in the gas turbine combustion chamber without a linkage mechanism. The generator rotor blades 101 and the compressor impeller shroud 102 are integrated into one unit, and the generator rotor 1, generator stator 2, and intake side end cover 411 are connected together by two rolling bearings 415. This integrated structure solves the problems of complex structure, large size, heavy weight, and high price of existing power generation equipment, making it more suitable for high-speed operation and use in mobile equipment.
[0063] In further embodiments of the present invention, such as Figures 13 to 16 As shown, based on the cycloidal equation constrained by the gear ratio of the internal and external gears in a specific positioning planetary gear set (n:n-1, n≥3 integers), multiple regular polygons with 3 sides, 4 sides, 5 sides, etc., and corresponding petal shapes with 2 petals, 3 petals, 4 petals, etc., can be derived. The number of petals is also called the number of leaves, which equals the number of sides minus one. Regular polygons and petal shapes can be used as the stator and rotor of the rotary piston engine 4, respectively. The regular polygons can be placed sideways on the stator, and the petal shapes can be placed sideways on the rotor, such as... Figures 5 to 8 As shown, the petal-shaped blades can also be placed on the stator, and the regular polygonal blades on the rotor. Because of the even number of power strokes, an even number series of blades (2, 4, 6...) is preferred. One combustion chamber is placed on each side or vertex of the corresponding regular polygon, so the number of combustion chambers equals the number of sides, i.e., an odd number of combustion chambers (3, 5, 7...). Placing the combustion chambers on the stator side offers more advantages.
[0064] In a further embodiment of the present invention, preferably, the end face of the combustion chamber cylinder 401 is a regular polygon, the end face of the blade rotor 405 is petal-shaped, and the number of blades of the blade rotor 405 is equal to the number of sides of the combustion chamber cylinder 401 minus one.
[0065] In a further embodiment of the present invention, preferably, the generator rotating blades 101 and the compressor impeller shroud 102 are integrated into one unit.
[0066] In a further embodiment of the present invention, preferably, a rolling bearing 415 is installed inside the turbine housing 3, and the turbine housing 3 and the eccentric main shaft 404 are rotatably connected by the rolling bearing 415. The turbine-side rolling bearing 415 is placed in the lower temperature zone outside the turbine.
[0067] In a further embodiment of the present invention, a turbine rotor 5 is provided between the turbine-side rolling bearing 415 and the exhaust-side end cover 403. The turbine-side rolling bearing 415 is mounted on the eccentric main shaft 404 and is as far away from the blade rotor body 405 as possible. The exhaust-side end cover 403 is provided with a plurality of exhaust ports 420. By increasing the distance between the turbine-side rolling bearing 415 and the exhaust-side end cover 403, the turbine-side rolling bearing 415 is placed in the lower temperature zone outside the turbine, reducing the temperature influence on the turbine-side rolling bearing 415 and extending the service life of the turbine-side rolling bearing 415.
[0068] In a further embodiment of the present invention, the integrated rotary piston gas turbine generator set with the same power output has a volume that is only 1 / 3 to 1 / 2 that of an internal combustion engine generator set, and its efficiency is higher than that of a gas turbine generator set with the same power output. It simplifies the structure, reduces size and weight, is inexpensive, and is easy to maintain. It is more suitable for high-speed operation and use in mobile equipment.
[0069] In a further embodiment of the present invention, the combustion chamber of the integrated rotary piston gas turbine generator set can burn fuels such as gasoline, diesel, aviation kerosene, alcohol, natural gas, and hydrogen without structural modifications. In particular, hydrogen combustion can achieve near-zero emissions, and compared with fuel cells, the requirements for hydrogen purity are not high.
[0070] In a further embodiment of the present invention, a rotary piston replaces the reciprocating piston of a conventional reciprocating piston internal combustion engine, and a turbine rotor 5 is used for turbocharging. The rotary piston rotor body 405 is as follows: Figures 9 to 12 As shown, the combustion chamber cylinder block 401 and the rotary piston have a simple structure and are easy to manufacture in simple 2D.
[0071] In a further embodiment of the present invention, a generator rotor 1 and a generator stator 2 are provided on the intake side of the rotary piston engine 4. The generator rotor 1 is driven to rotate in the generator stator 2 by the rotary piston engine 4. A silicon steel core coil 201 is provided in the generator stator 2. The permanent magnet 103 on the generator rotor 1 continuously cuts the magnetic field lines to realize the power generation function.
[0072] In a further embodiment of the present invention, a combustion chamber is provided inside the rotary piston engine 4, that is, multiple partitioned combustion chambers are provided between the inner wall of the combustion chamber cylinder 401 and the outer wall of the vane rotor 405. Fuel is injected into the combustion chamber through the fuel injector 417 and ignited by the spark plug 416, driving the vane rotor 405 to rotate. The vane rotor 405 drives the eccentric position of the eccentric main shaft 404 to move within the engine housing 418. The gear shaft 406 and the large gear ring 412 mesh, causing the gear shaft to... 406 moves along the internal teeth of the large gear ring 412. Under the action of the large gear ring 412, the blade rotor body 405 and the eccentric main shaft 404 rotate synchronously but in opposite directions. The blade rotor body 405 drives the eccentric main shaft 404 to rotate. The intake side eccentric shaft 410 and the eccentric main shaft 404 are connected and fixed by a pin. The generator rotor 1 is mounted on the intake side eccentric shaft 410, and the turbine rotor 5 is mounted on the eccentric main shaft 404. The generator rotor 1 and the turbine rotor 5 are located on the same axis. Figure 20 As shown, the rotary piston engine 4 and the turbine rotor 5 drive the generator rotor 1 to rotate synchronously.
[0073] In a further embodiment of the present invention, the generator rotor 1 is composed of rotating blades 101 and a surrounding belt 102. Permanent magnets 103 are arranged along the surrounding belt 102 for generating electricity. The rotating blades 101 rotate with the intake side eccentric shaft 410, continuously inputting air into the rotary piston engine 4, thereby increasing the working efficiency of the rotary piston engine 4.
[0074] In a further embodiment of the present invention, the rotary piston engine 4 employs an eccentric main shaft 404, on which a vane rotor 405 is mounted. A gear shaft 406 is mounted on the vane rotor 405, and a large gear ring 412 is mounted on the intake side end cover 411. The gear shaft 406 and the large gear ring 412 mesh. After the vane rotor 405 rotates and drives the eccentric portion of the eccentric main shaft 404 to move within the engine housing 418, the movement is achieved through the gear shaft 406 and the large gear ring 412. Figures 5 to 8 The equation of motion for the cycloid is shown in the figure.
[0075] In a further embodiment of the present invention, the exhaust-side end cap 403 and the eccentric main shaft 404 are sealed by the exhaust-side small cover 409.
[0076] In a further embodiment of the present invention, the combustion chamber is connected to the outer wall of the blade rotor body 405, thereby increasing the working efficiency of the rotary piston engine 4.
[0077] In a further embodiment of the present invention, the spring radial seal 402 is used to separate the combustion chamber, and a spring plate is provided thereon to facilitate the rotation of the blade rotor 405 within the combustion chamber cylinder 401.
[0078] In a further embodiment of the present invention, the blade rotor body 405 is as follows: Figures 9 to 12 As shown, the intake side has an intake chamber communicating with its outer wall, and the exhaust side has an exhaust chamber communicating with its outer wall. The blade rotor 405 is sleeved on the eccentric main shaft 404 through the bushing 408, and the gear shaft 406 is sleeved on the eccentric main shaft 404. The blade rotor 405 and the gear shaft 406 are connected by a flat key 407. After the rotary piston engine 4 is running, the fuel injector 417 injects fuel into the combustion chamber in the combustion chamber cylinder 401 and ignites it through the spark plug 416, which drives the blade rotor 405 to rotate in the combustion chamber cylinder 401. During the rotation of the blade rotor 405, air is introduced into the combustion chamber through the intake chamber on its intake side, and the next blade of the blade rotor 405 compresses the air in the combustion chamber. After fuel is injected through the fuel injector 417 and ignited by the spark plug 416, the exhaust gas after combustion is discharged through the exhaust chamber on its exhaust side. At the same time, the discharged exhaust gas is used to drive the turbine rotor 5 to rotate in the turbine mount 3.
[0079] In a further embodiment of the present invention, the blade rotor body 405 is sleeved on the eccentric position of the eccentric main shaft 404 through the bushing 408, so that the blade rotor body 405 can compress the combustion chamber in the combustion chamber cylinder block 401 during rotation. At the same time, the gear shaft 406 meshes with the large gear ring 412 assembled on the intake side end cover 411, realizing the rotation of the eccentric main shaft 404, and the rotation direction of the eccentric main shaft 404 is opposite to that of the blade rotor body 405.
[0080] In a further embodiment of the present invention, the generator rotor 1 is composed of rotating blades 101, a surrounding belt 102, and permanent magnets 103. The rotating blades 101 are mounted on the intake-side eccentric shaft 410, and the outer edge of the rotating blades 101 is connected to the surrounding belt 102. A plurality of permanent magnets 103 are mounted around the surrounding belt 102, such as... Figure 17 and Figure 18 As shown.
[0081] In a further embodiment of the present invention, the eccentric main shaft 404 and the intake side eccentric shaft 410 are connected by pins. The eccentric main shaft 404 and the intake side eccentric shaft 410 form a crankshaft with both ends located on the same axis. The rotating blades 101 are mounted on the intake side eccentric shaft 410. After the crankshaft is driven to rotate by the rotary piston engine 4 and the turbine rotor 5, it drives the generator rotor 1 to rotate. The generator stator 2 is provided with a silicon steel core coil 201. The permanent magnet 103 on the generator rotor 1 continuously cuts the magnetic field lines to achieve the power generation function. At the same time, it drives the rotating blades 101 of the generator rotor 1 to rotate, continuously inputting air into the rotary piston engine 4 and increasing the working efficiency of the rotary piston engine 4.
[0082] In a further embodiment of the present invention, the blade rotor body 405 is sleeved on the eccentric main shaft 404 by a bushing 408, and the eccentric main shaft 404 can rotate freely within the blade rotor body 405 by setting the bushing 408.
[0083] In a further embodiment of the present invention, the rotary piston gas turbine generator set consists of three parts: a generator, an internal combustion engine, and a turbine. The generator rotor 1 is driven to rotate within the generator stator 2 by the rotary piston engine 4 and the turbine rotor 5 to achieve the power generation function. At the same time, air is input to the rotary piston engine 4 through the rotating blades 101 of the generator rotor 1, increasing the working efficiency of the rotary piston engine 4. By replacing the reciprocating piston of the existing reciprocating piston internal combustion engine with a rotary piston and using the turbine rotor for turbocharging, the structure is simplified and the volume and weight are reduced. Its volume is only 1 / 3 to 1 / 2 of that of an internal combustion engine generator set, and its efficiency is higher than that of a gas turbine generator set of the same power. This solves the problems of complex structure, large size, heavy weight, and high price of existing power generation equipment.

Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
