Description

Technical Field

[0001] This invention belongs to the field of generator set technology, specifically relating to a high-efficiency energy-saving generator set. Background Technology

[0002] A generator set, also commonly known as a generator, is an independent device that converts other forms of energy (such as the chemical energy of fuels, wind energy, solar energy, etc.) into electrical energy. The generator set we usually refer to specifically means a complete set of equipment consisting of an engine (providing mechanical energy), a generator (converting mechanical energy into electrical energy), and a control system. Its core working principle is that the prime mover (engine) burns fuel (such as diesel, gasoline, natural gas) to generate rotational mechanical energy, which drives the generator (AC generator) through the main shaft. The rotor magnetic field inside the generator cuts the stator coils, generating electrical energy based on the principle of electromagnetic induction.

[0003] For generator sets, "high efficiency" means minimizing losses in the process of converting the chemical energy of fuels (such as diesel and natural gas) into usable electrical energy. It directly relates to operating costs, fuel consumption, environmental impact, and long-term economic benefits.

[0004] Energy-saving generator sets refer to generator sets with the lowest overall energy consumption and the highest energy utilization rate throughout the entire operating cycle.

[0005] The authorized publication number "CN209067341U" describes a "high-efficiency energy-saving diesel generator set, including a base, support frame, diesel engine, spiral duct, solar panel, air intake pipe, purification tank, and drying chamber. Four casters are evenly distributed below the base, each equipped with a brake pedal. A support frame is installed above the base, and the support frame is fixedly connected to the base by welding. The generator set is installed on the left side above the base, the diesel engine on the right side of the generator set, and the purification tank on the right side of the water tank. This invention uses an inlet pipe and spiral duct for water cooling of the generator set. The heat emitted by the generator set preheats the cold water in the spiral duct, improving waste heat utilization. The preheated water enters the water tank through a micro-pump, where the waste heat from the diesel engine exhaust continues to heat the water. The heated water can then be used for daily life and production, making it more energy-efficient and environmentally friendly."

[0006] The aforementioned patent utilizes a water inlet pipe and a spiral conduit for water cooling of the generator set. The heat emitted by the generator set preheats the cold water in the spiral conduit, improving waste heat utilization. The preheated water is then pumped into a water tank by a micro-pump, where it is further heated by the waste heat from the diesel engine exhaust. This heated water can then be used for daily life and production, making it more energy-efficient and environmentally friendly. A purification tank is included to purify the exhaust gas produced by the diesel engine, which is then treated through a filter and drying chamber before being discharged, preventing air pollution. A fan and a booster pump are installed to ensure more complete and efficient combustion of diesel fuel in the engine. Solar panels are also included to charge the battery, providing power for the daily use of the diesel generator set, further enhancing energy efficiency and environmental friendliness. However, the waste heat generated during diesel power generation cannot be recovered for power generation, limiting the diesel utilization efficiency of the generator and preventing further improvement in power generation efficiency. Furthermore, it lacks an automatic adjustment function for power generation based on temperature differences, making temperature difference power generation unsuitable for the same diesel engine under different load conditions. Therefore, we propose a high-efficiency energy-saving generator set. Summary of the Invention

[0007] The purpose of this invention is to provide a high-efficiency and energy-saving generator set, which aims to provide both hot and cold poles for thermoelectric power generation by exporting hot water from the cooling cylinder liner of the diesel engine and guiding the cold air produced by the compressor into the same space, thereby providing a temperature difference for thermoelectric power generation. Then, the waste heat emitted by the diesel generator is used to generate electricity, thereby improving the diesel utilization efficiency of the diesel power generation process. At the same time, by automatically adjusting the rotation of the thermoelectric generator, the thermoelectric generator can adapt to different loads and the power generation needs of the waste heat emitted by the diesel engine.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In this solution, the hot circulation component removes hot water from the diesel engine's cooling cylinder liner, and the cold circulation component guides the cold air produced by the compressor into the same space, providing both hot and cold poles for thermoelectric power generation, and providing a temperature difference for thermoelectric power generation. Then, the waste heat dissipated by the diesel generator is used to generate electricity. At the same time, the heat pipe is used to introduce the high-temperature air generated during the compressor's cooling process into the diesel engine, providing high-pressure gas to the diesel engine's fuel injectors. The warm air can also improve the atomization and combustion rate of diesel in the diesel engine, thereby increasing the diesel combustion efficiency of the diesel engine. Under the same output power, the amount of diesel burned is reduced, thereby saving diesel consumption of the diesel generator and improving the diesel utilization efficiency of the diesel generator process.

[0025] 2. In this scheme, when the multiple arc-shaped thermocouples are axially deflected, the lead screw pushes the slider to reciprocate within the track through the sliding engagement with the slider. The slider then pushes two reciprocating rods to extend and retract at the side end of the track, so that the two reciprocating rods can push the telescopic rod to reciprocate within the regulating box. Utilizing the self-locking function of the lead screw and slider, the axial deflection angle of the multiple arc-shaped thermocouples is effectively limited, thereby controlling the contact area between the multiple arc-shaped thermocouples and the heat source to be constant. This ensures that the output current of the power generation generated by the multiple arc-shaped thermocouples in series is constant when the temperature inside the inner box is constant, thus meeting the power generation needs of a fixed load.

[0026] 3. In this solution, when a single arc-shaped thermocouple is axially deflected, the telescopic rod pushes and pulls the driven rod to deflect it, and the driven rod pushes and pulls the driving rod to deflect it. The driving rod drives the arc-shaped frame to axially deflect around the condenser tube, changing the contact area between the arc-shaped thermocouple and the heating side of the condenser tube. By changing the area of ​​the arc-shaped thermocouple in contact with the heat source, the power generation of a single arc-shaped thermocouple is controlled. As the temperature inside the inner chamber decreases, the contact area between each arc-shaped thermocouple and the heat source increases, or as the temperature inside the inner chamber increases, the contact area between each arc-shaped thermocouple and the heat source decreases. This allows the power generation of multiple arc-shaped thermocouples to remain constant within a specific temperature range, avoiding damage to other power generation components caused by voltage fluctuations.

[0027] 4. In this scheme, when multiple arc-shaped thermocouples are axially deflected, two reciprocating rods push the telescopic rod to move back and forth within the regulating box. The guide block guides the movement of the telescopic rod through sliding cooperation with the rail groove. At the same time, the fixed sleeve provides auxiliary support to the other end of the telescopic rod, so that the telescopic rod pushes and pulls multiple driven rods synchronously within the regulating box, thereby achieving synchronous deflection of multiple arc-shaped thermocouples. This ensures synchronous current changes during the series power generation process of multiple arc-shaped thermocouples, avoids overload burnout of a single arc-shaped thermocouple when it has not moved, and reduces the maintenance difficulty of the generator set.

At the same time, the warm air can improve the atomization and combustion rate of diesel in the diesel engine 2, thereby increasing the diesel combustion efficiency of the diesel engine 2. Under the same output power, the amount of diesel burned is reduced, thereby saving the amount of diesel used by the diesel generator. By exporting the hot water in the cooling cylinder liner of the diesel engine and guiding the cold air produced by the compressor into the same space, cold and hot poles are provided for thermoelectric power generation, and temperature difference is provided for thermoelectric power generation.

The lead screw 21 pushes the slider 22 to reciprocate within the track 18 through sliding engagement with the slider 22. The slider 22 reciprocates by pushing and pulling the two reciprocating rods 23. The two limiting blocks 20 guide and restrict the movement of the slider 22 through sliding engagement with the two limiting grooves 19, thereby limiting the extreme range of movement of the slider 22. The two reciprocating rods 23 push and pull the telescopic rod 15, causing the telescopic rod 15 to reciprocate within the lead screw 21, thereby axially deflecting the multiple arc-shaped temperature differential plates 39. At this time, the lead screw 21 pushes the slider 22 to reciprocate within the track 18 through the sliding engagement with the slider 22. The slider 22 then pushes the two reciprocating rods 23 to extend and retract at the side end of the track 18, so that the two reciprocating rods 23 can push the telescopic rod 15 to reciprocate within the regulating box 12. Utilizing the self-locking function of the lead screw 21 and the slider 22, the axial deflection angle of the multiple arc-shaped temperature differential plates 39 is effectively limited, thereby controlling the contact area between the multiple arc-shaped temperature differential plates 39 and the heat source to be constant. This ensures that the output current of the power generation generated by the multiple arc-shaped temperature differential plates 39 in series is constant under the condition that the temperature inside the inner box layer 5 is constant, thus adapting to the power generation needs of a fixed load.

[0061] The guiding assembly includes a telescopic rod 15, a rail groove 16, a guide block 17, and a fixing sleeve 41. The telescopic rod 15 is disposed between the inner walls of the regulating box 12. One end of the telescopic rod 15 extends through to the side end of the regulating box 12, and the other end of the telescopic rod 15 is connected to two reciprocating rods 23. The rail groove 16 is opened at the top of the telescopic rod 15. The guide block 17 slides between the inner walls of the rail groove 16 and is fixedly connected to the inner wall of the regulating box 12. The fixing sleeve 41 wraps around the circumferential surface of the telescopic rod 15 and is fixedly connected to the inner wall of the regulating box 12.

[0062] In this invention, the telescopic rod 15 moves by reciprocatingly pushing multiple sets of connecting rod assemblies. The rail groove 16 accommodates the sliding of the guide block 17. The guide block 17 guides the telescopic rod 15 to reciprocate through sliding engagement with the rail groove 16. The fixing sleeve 41 provides auxiliary support for the other end of the telescopic rod 15. When the multiple arc-shaped temperature difference plates 39 are axially deflected, the two reciprocating rods 23 push the telescopic rod 15 to reciprocate within the adjusting box 12. The guide block 17, through sliding engagement with the rail groove 16, guides the telescopic rod 15 to reciprocate. The movement of the telescopic rod 15 is guided, while the fixed sleeve 41 provides auxiliary support to the other end of the telescopic rod 15, so that the telescopic rod 15 pushes and pulls multiple driven rods 13 synchronously within the regulating box 12, thereby achieving synchronous deflection of multiple arc-shaped thermocouples 39. This ensures synchronous current changes during the series power generation process of multiple arc-shaped thermocouples 39, preventing overload burnout of a single arc-shaped thermocouple 39 when no displacement occurs, and reducing the maintenance difficulty of the generator set.

[0063] The linkage assembly includes an arc-shaped frame 11, a driven rod 13, a driving rod 14, and bearings 29. Two bearings 29 are provided. The arc-shaped frame 11 is rotatably connected to the inner wall of the sleeve 9 through the two bearings 29. The arc-shaped frame 11 is fitted onto the circumferential surface of the condenser tube 10. The top of the arc-shaped frame 11 extends to the top of the sleeve 9. The extended end of the arc-shaped frame 11 is located between the inner walls of the regulating box 12, and the arc-shaped frame 11 is connected to the arc-shaped temperature difference plate 39. The driving rod 14 is fixedly connected to the top extended end of the arc-shaped frame 11. The driven rod 13 is rotatably connected to the bottom of the telescopic rod 15, and the driven rod 13 is rotatably connected to the driving rod 14.

[0064] In this invention, in each linkage assembly, two bearings 29 support the arc-shaped frame 11, which in turn supports and fixes the arc-shaped thermocouple 39. Simultaneously, the arc-shaped frame 11 transfers the cooling capacity from the condenser tube 10 to the arc-shaped inner surface of the thermocouple 39. The driving rod 14 drives the arc-shaped frame 11 to rotate axially, and the driven rod 13 pushes and pulls the driving rod 14 to rotate it. When rotating a single arc-shaped thermocouple 39 axially, the telescopic rod 15 pushes and pulls the driven rod 13 to rotate, and the driven rod 13 pushes and pulls the driving rod 14 to rotate. The driving rod 14 drives the arc-shaped frame 11 to rotate around the condenser tube 10. Axial deflection changes the contact area between the arc-shaped thermocouple 39 and the heating side of the condenser tube 10. By changing the contact area of ​​the arc-shaped thermocouple 39 with the heat source, the power generation of a single arc-shaped thermocouple 39 is controlled. As the temperature inside the inner chamber 5 decreases, the contact area between each arc-shaped thermocouple 39 and the heat source increases; or as the temperature inside the inner chamber 5 increases, the contact area between each arc-shaped thermocouple 39 and the heat source decreases. This ensures that within a specific temperature range, the power generation of multiple arc-shaped thermocouples 39 remains constant regardless of temperature changes, thus preventing voltage fluctuations from damaging other power generation components.

[0065] The drive assembly includes a driven gear 24, a driving gear 25, a gear cover 26, and a servo motor 27. The gear cover 26 is sleeved on the extension end of the lead screw 21 and is fixedly connected to the side end of the regulating box 12. The driven gear 24 is fixedly connected to the extension end of the lead screw 21 and is located between the inner walls of the gear cover 26. The servo motor 27 is fixedly connected to the inner wall of the regulating box 12 and its output end extends to the inner wall of the gear cover 26. The driving gear 25 is fixedly connected to the extension end of the servo motor 27 and is located between the inner walls of the gear cover 26. The driving gear 25 meshes with the driven gear 24.

[0066] In this invention, the gear cover 26 is used to seal and protect the driven gear 24 and the driving gear 25. The driven gear 24 is used to drive the lead screw 21 to rotate, and the servo motor 27 is used to drive the driving gear 25 to rotate. The driving gear 25 drives the driven gear 24 to rotate through meshing with the driven gear 24. When the multiple arc-shaped temperature difference plates 39 are axially deflected, the servo motor 27 is powered on and started. The output end of the servo motor 27 drives the driving gear 25 to rotate. The driving gear 25 drives the driven gear 24 to rotate through meshing with the driven gear 24. The driven gear 24 then drives the lead screw 21 to rotate, thereby providing power for the axial deflection of the multiple arc-shaped temperature difference plates 39.

[0067] The positioning component includes an infrared rangefinder 40, which is fixedly connected to the side end of the telescopic rod 15 and is located between the inner walls of the adjustment box 12.

[0068] In this invention, the infrared rangefinder 40 emits an infrared laser to the lead screw 21 to detect the reciprocating movement distance of the telescopic rod 15 in the regulating box 12 in real time, and calculates the axial deflection angle of the multiple arc-shaped temperature differential plates 39 based on the deflection angle corresponding to the reciprocating movement distance. The contact area between the multiple arc-shaped temperature differential plates 39 and the heat source on one side of the condenser tube 10 is calculated by the deflection angle of the multiple arc-shaped temperature differential plates 39, which facilitates the overall calculation of the rated power generation.

[0069] A generator 3 is fixedly connected to the top of the base frame 1, and the generator 3 is connected to the output end of the outer casing layer 4.

[0070] In this invention, the generator 3 is used to drive the rotation of the rotor inside the outer casing layer 4, and the outer casing layer 4 is used to convert mechanical energy into electrical energy.

[0071] A method for using a high-efficiency, energy-saving generator set includes the following steps:

[0072] S1. Waste heat collection:

[0073] During the diesel power generation process, the waste heat generated by diesel combustion in the diesel engine cylinder liner is conducted and absorbed by the water in the cooling cylinder liner, which heats the water in the cooling cylinder liner. The heated water is then introduced into the inner tank layer 5 through the hot water pipe 7 to heat the water in the inner tank layer 5. The heat collected by the cooling cylinder liner is circulated and guided to the inner tank layer 5 by the one-way pump connected in series with the hot water pipe 7, thus realizing the collection of waste heat during the operation of the diesel engine 2.

[0074] S2, Recirculating Cooling:

[0075] While collecting waste heat, the compressor 32 is powered on and started. The compressor 32 compresses the air, and a small portion of the compressed air, along with the heat generated during the air compression process, is introduced from the heat pipe 34 into the fuel injector of the diesel engine 2 to provide power for diesel injection in the diesel engine 2. At the same time, the diesel is preheated to improve the combustion efficiency of the diesel. Meanwhile, the cold air generated by the compressor 32 is introduced into the diffuser 37 through a cold pipe 33. The cold air is then distributed to multiple condenser pipes 10 through a diffuser 37 and a throttle valve 38 to conduct cooling to multiple arc-shaped frames 11. At the same time, it is concentrated again from another diffuser 37 and a throttle valve 38 into another cold pipe 33, and then flows back to the compressor 32 from the other cold pipe 33. During this process, the refrigerant circulates in the two cold pipes 33, the two diffusers 37, the two throttle valves 38, and the multiple condenser pipes 10 to provide cooling to the multiple arc-shaped frames 11, thereby achieving circulating cooling of the arc-shaped inner surface of multiple arc-shaped temperature differential plates 39.

[0076] S3, Fixed-quota power generation:

[0077] The inner curved surfaces of the multiple arc-shaped thermocouples 39 receive the cooling energy conducted by the multiple arc-shaped supports 11, while the outer curved surfaces of the multiple arc-shaped thermocouples 39 receive the heat conducted by one side of the multiple condenser tubes 10. This causes the P / N junctions in the multiple arc-shaped thermocouples 39 to generate electricity due to thermoelectricity. At this time, the servo motor 27 is started by powering on. The output of the servo motor 27 drives the drive gear 25 to rotate. The drive gear 25 drives the driven gear 24 to rotate through meshing with the driven gear 24. The driven gear 24 drives the lead screw 21 to rotate. The lead screw 21 pushes the slider 22 to reciprocate within the track 18 through sliding engagement with the slider 22. The slider 22 drives two reciprocating rods 23 to move. The two reciprocating rods 23 drive the telescopic rod 15 to reciprocate within the regulating box 12. The telescopic rod 15 pushes and pulls multiple driven rods 13 to move. Multiple driven rods 13 push and pull multiple active rods 14, which in turn drive multiple arc-shaped frames 11 to rotate axially. The arc-shaped frames 11 drive multiple arc-shaped thermocouples 39 to rotate axially, adjusting with the temperature change inside the inner chamber 5. This changes the contact area between the multiple arc-shaped thermocouples 39 and the heat source on one side of the condenser tube 10, ensuring that the thermoelectric current generated by the multiple arc-shaped thermocouples 39 is constant. At the same time, during the axial deflection of the multiple arc-shaped thermocouples 39, the self-locking function of the lead screw 21 and the slider 22 effectively limits the axial deflection angle of the multiple arc-shaped thermocouples 39, thereby controlling the contact area between the multiple arc-shaped thermocouples 39 and the heat source to be constant. This ensures that the output current of the multiple arc-shaped thermocouples 39 in series is constant when the temperature inside the inner chamber 5 is constant, adapting to the power generation needs of a fixed load and achieving rated power generation.
