Description

Technical Field

[0001] The present invention relates to the technical field of internal combustion engines and generators, and particularly to an integrated rotary piston gas turbine generator set. Background Art

[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, and is driven by a water turbine, steam turbine, diesel engine or other power machinery. It converts the energy generated by the flow of water, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, and then the generator converts it into electrical energy and outputs it for use on electrical equipment. The existing generator sets for range-extended electric vehicles, electric drive agricultural machinery and tractors, all-electric drive ships, heavy-duty electric aircraft and engineering sites without mains power are complex in structure, large in size and heavy in weight, and high in price, and there is an urgent need for upgrading.

[0003] The operating speed and power of the range extender of a range-extended electric vehicle are completely decoupled from the vehicle, and are not restricted by the vehicle's driving speed. The vehicle drive equipment can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids. Common gasoline engines and diesel engines belong to reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement and output power externally. However, reciprocating piston internal combustion engines use a single fuel, have a relatively large mass, and occupy a relatively large space during the reciprocating movement of the piston.

[0004] An aeroengine, also known as an aircraft engine, is a device that converts the thermal energy of fuel or other forms of energy into mechanical energy and provides power for aircraft, helicopters and other aircraft. It is a highly complex and precise thermal machine and is an engine that provides the power required for aircraft flight. It has the advantage of being light in weight. However, due to its low efficiency and high price, it is difficult to be directly applied to electric vehicles.

[0005] Generally speaking, the existing reciprocating piston engines used in automobiles, airplanes, ships and tractors have relatively high working efficiency and relatively low price. Their biggest problems are large volume and heavy weight, and their application scope is limited. An aeroengine (mostly used in airplanes, and can also be used on ships or tank vehicles) is essentially a gas turbine. Compared with a reciprocating piston engine, it has no piston and other parts, and is a rotary engine (impeller machinery). It can be made relatively small in volume and light in weight under the same output power. Its disadvantages are low working efficiency and high price. Under the same output power, the efficiency of a reciprocating piston engine (generator set) can reach about 40%, and the efficiency of a gas turbine (generator set) is difficult to reach 30%. The weight of a gas turbine is less than one-half of that of a reciprocating piston engine, and the price of a gas turbine is about 10 times that of a reciprocating piston engine. Therefore, there is an urgent need for a generator set with high efficiency, small volume, light weight and low cost. Summary of the Invention

[0055] The present invention further has the following implementation manners on the above basis:

[0056] In a further embodiment of the present invention, the present invention discloses an integrated rotary piston gas turbine generator set, which is composed 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 the fixed parts of the whole are defined as the stator part, and the stator part is a component of the integrated rotary piston gas turbine generator set. All the rotatable parts of the whole are defined as the rotor part, and the rotor part is a component fixed on a crankshaft. The crankshaft is composed of an intake-side eccentric shaft 410 and an eccentric main shaft 404. The intake-side eccentric shaft 410 and the eccentric main shaft 404 are fixedly connected by a pin. One end of the crankshaft on the rotor part is rotatably connected to the intake-side bearing seat 413 of the stator part through two rolling bearings 415, and the other end of the crankshaft on the rotor part and the turbine seat 3 of the stator part are rotatably connected through a rolling bearing 415. It is an integrated structure that connects the stator part, the rotor part, the intake-side end cover 411 and the exhaust-side end cover 403 together through three bearings.

[0058] In a further embodiment of the present invention, an integrated rotary piston gas turbine generator set includes a stator part. Inside the stator part, there are a generator stator frame 202, a combustion chamber cylinder block 401, a silicon steel core coil 201, an intake-side bearing cover 414, an intake-side end cover 411 and an intake-side bearing seat 413. The silicon steel core coil 201 is composed of a generator iron core and a coil. The intake-side end cover 411 installs and positions the large gear ring 412 of the planetary gear set. Front and rear rolling bearings 415 are respectively installed on the intake-side bearing seat 413 and the turbine seat 3. The rolling bearings 415 carry the rotor part. The rotor part is composed of a compressor rotating blade 101 on the same crankshaft, a generator permanent magnet 103 on the shroud 102, a turbine rotor 5, a rotary piston rotating on the crank segment and a positioning planetary gear set gear shaft 406. The rotary piston is the blade rotor body 405.

[0059] In a further embodiment of the present invention, this invention patent relates to the technical fields of internal combustion engines and generators. It is proposed that by burning gas or oil in the cylinder to generate heat to push the rotary piston blade rotor body 405 to rotate and then push the turbine rotor 5 to rotate, the rotational forces of the blade rotor body 405 and the turbine rotor 5 drive the compression system to ensure the intake air and pressure of the combustion chamber, and drive the coaxial generator to generate electricity. The rotary piston replaces the reciprocating piston of the existing reciprocating piston internal combustion engine, and uses the turbine rotor 5 for turbocharging. While reducing the mass, the volume of the engine is also reduced. For a rotary piston gas turbine generator set with the same power, the volume is only about 1 / 3 to 1 / 2 of that of the existing internal combustion engine generator set. 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, has a low price, is reliable in operation, is durable, and has a relatively high operating efficiency, and is more suitable for high-speed operation.

[0060] In a further embodiment of the present invention, a rotary piston is used to replace 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 set, the volume and mass of the rotary piston gas turbine generator set are halved, and the power generation efficiency is the same.

[0061] In a further embodiment of the present invention, an integrated rotary piston gas turbine generator set proposed in this patent generates heat by burning gas or oil in a cylinder to push the blade rotor body 405 to rotate, and then pushes the turbine rotor 5 to rotate. The rotational forces of the blade rotor body 405 and the turbine rotor 5 drive the compression system to ensure the intake air and pressure of the combustion chamber, and drive a coaxial generator to generate electricity. By using a rotary piston to replace the reciprocating piston of the existing reciprocating piston internal combustion engine and using the turbine rotor 5 for turbocharging, the mass is reduced while the volume of the engine is decreased. For a rotary piston gas turbine generator set with the same power, the volume is only about 1 / 3 to 1 / 2 of that 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, has a low price, is reliable in operation, is durable, and has a relatively high operating efficiency, and is more suitable for high-speed operation.

[0062] In a further embodiment of the present invention, according to the cycloid curve equation, a series of rotary piston propulsion systems with different numbers of combustion chambers are given, such as Figures 13 to 16 shown. Compared with the existing internal combustion engine set, the pressure of the gas turbine combustion chamber is increased without a connecting rod mechanism. The generator rotating blade 101 and the compressor impeller shroud 102 are integrated into one body, and an integrated structure that connects the generator rotor 1, the generator stator 2, and the intake side end cover 411 together through two rolling bearings 415. It solves the problems of the existing power generation equipment such as complex structure, large volume, heavy weight, and high price, and is more suitable for high-speed operation and for mobile equipment.

[0063] In a further embodiment of the present invention, as Figures 13 to 16 shown, according to the cycloid equation defined by the tooth number ratio (n:n - 1, n≥3 integer) of the internal and external gears of a specific positioning planetary gear set, multiple regular polygons such as 3-sided, 4-sided, 5-sided... and corresponding petal shapes such as 2-petal, 3-petal, 4-petal... can be obtained. The number of petals is also called the number of leaves, and the number of leaves is equal to the number of sides minus one. The regular polygon and the petal shape can be used as the stator and rotor of the rotary piston engine 4 respectively. The regular polygon can be placed on the stator side and the petal shape on the rotor side, as Figures 5 to 8 shown, or the petal shape can be placed on the stator side and the regular polygon on the rotor side. Due to the evenness of the power stroke, an even series with the number of leaves = 2, 4, 6... is preferably selected. One combustion chamber is arranged on each side or vertex of the corresponding regular polygon, so the number of (combustion) chambers is equal to the number of sides, that is, the number of combustion chambers = 3, 5, 7... odd numbers. It has more advantages to place the combustion chamber on the stator side.

[0064] In a further embodiment of the present invention, preferably, the end face of the combustion chamber cylinder block 401 is a regular polygon, the end face of the vane rotor body 405 is petal-shaped, and the number of vanes of the vane rotor body 405 is equal to the number of sides of the combustion chamber cylinder block 401 minus one.

[0065] In a further embodiment of the present invention, preferably, the generator rotating blade 101 and the compressor impeller shroud 102 are integrated into one body.

[0066] In a further embodiment of the present invention, preferably, a rolling bearing 415 is installed in the turbine housing 3, and the turbine housing 3 and the eccentric main shaft 404 are rotatably connected through the rolling bearing 415, and the turbine-side rolling bearing 415 is placed in the relatively low-temperature area 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 installed on the eccentric main shaft 404 and is as far away from the vane rotor body 405 as possible. A plurality of exhaust ports 420 are provided on the exhaust-side end cover 403. By lengthening 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 relatively low-temperature area 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, for the same power, the volume of the integrated rotary piston gas turbine generator set is only 1 / 3 to 1 / 2 of that of the internal combustion engine generator set, the efficiency is higher than that of the gas turbine generator set with the same power, the structure is simplified, the volume and weight are reduced, the price is cheap, and the maintenance is convenient. It is more suitable for high-speed operation and for mobile devices.

[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, alcohols, natural gas, and hydrogen without structural modification. In particular, when burning hydrogen, it can achieve near-zero emissions. Compared with fuel cells, the requirement for hydrogen purity is not high.

[0070] In a further embodiment of the present invention, the reciprocating piston of the existing reciprocating piston internal combustion engine is replaced by a rotary piston, and the turbine rotor 5 is used for turbocharging. The rotary piston vane rotor body 405 is as Figures 9 to 12 shown. The combustion chamber cylinder block 401 and the rotary piston have a simple structure and are easy to manufacture in simple 2D.

After fuel is injected into the combustion chamber through the fuel injector 417 and ignited by the spark plug 416, the vane rotor body 405 is driven to rotate. The vane rotor body 405 drives the eccentric position of the eccentric main shaft 404 to move within the engine housing 418. The gear shaft 406 meshes with the large gear ring 412, causing the gear shaft 406 to move along the internal teeth of the large gear ring 412. Under the action of the large gear ring 412, the vane rotor body 405 and the eccentric main shaft 404 rotate synchronously and in opposite directions.

Permanent magnets 103 are arranged along the shroud 102 for power generation.

The vane rotor body 405 and the gear shaft 406 are connected by a flat key 407. After the rotary piston engine 4 operates, the fuel injector 417 sprays fuel into the combustion chamber within the combustion chamber cylinder block 401 and ignites it through the spark plug 416, pushing the vane rotor body 405 to rotate within the combustion chamber cylinder block 401. During the rotation of the vane rotor body 405, air is introduced into the combustion chamber through the intake chamber on its intake side, and the air within the combustion chamber is compressed by the next vane of the vane rotor body 405. After spraying fuel through the fuel injector 417 and igniting it through the spark plug 416, the burned exhaust gas 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 within the turbine housing 3.

[0079] In a further embodiment of the present invention, the vane rotor body 405 is sleeved at an eccentric position of the eccentric main shaft 404 through a bushing 408, enabling the vane rotor body 405 to compress the combustion chamber within 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 directions of the eccentric main shaft 404 and the vane rotor body 405 are opposite.

[0080] In a further embodiment of the present invention, the generator rotor 1 is composed of rotating blades 101, a shroud 102, and permanent magnets 103.

A crankshaft is formed by the eccentric main shaft 404 and the intake-side eccentric shaft 410. Both ends of the crankshaft are located on the same axis. The rotating blade 101 is installed 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, the generator rotor 1 is driven to rotate. 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 induction lines to realize the power generation function. At the same time, the rotating blade 101 driving the generator rotor 1 rotates, continuously inputs air into the rotary piston engine 4, and increases the working efficiency of the rotary piston engine 4.

[0082] In a further embodiment of the present invention, the vane rotor body 405 is sleeved on the eccentric main shaft 404 through a bushing 408. By providing the bushing 408, the eccentric main shaft 404 can freely rotate within the vane rotor body 405.

[0083] In a further embodiment of the present invention, the rotary piston gas turbine power generation 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 realize the power generation function. At the same time, air is input into the rotary piston engine 4 through the rotating blade 101 of the generator rotor 1, increasing the working efficiency of the rotary piston engine 4. The rotary piston is used to replace the reciprocating piston of the existing reciprocating piston internal combustion engine, and the turbine rotor is used for turbocharging, simplifying the structure, reducing the volume and weight. Its volume is only 1 / 3 to 1 / 2 of that of the internal combustion engine power generation set, and the efficiency is higher than that of the gas turbine power generation set with the same power, solving the problems of the existing power generation equipment such as complex structure, large volume, heavy weight, and high price.

[0084] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
