Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically to a silent generator set adapted to high-altitude, cold, and high-temperature environments. Background Technology

[0002] With the diversification of energy demands, generator sets, as core equipment for emergency power supply and power supply in remote areas, are now widely used in extreme environments such as plateaus, deserts, and polar regions. Among these, silent generator sets, due to their low noise pollution advantage, are increasingly in demand in scenarios requiring noise control, such as outdoor operations, emergency power supply in scenic areas, plateau scientific research stations, and high-temperature mining areas. However, existing silent generator sets exhibit numerous technical deficiencies when adapting to both high-altitude and high-temperature extreme environments, severely impacting their operational stability, reliability, and ease of maintenance, making it difficult to meet the needs of use in extreme environments.

[0003] In high-altitude, frigid environments, the air often contains sand, dust, and snow particles, causing rapid clogging of the filter mesh. Similarly, in high-temperature environments, the high dust content in the air and the accelerated adsorption and accumulation of dust on the filter surface also easily lead to clogging. Once the filter is clogged, the cooling airflow circulation inside the generator set is obstructed, preventing the timely dissipation of heat generated by the engine and generator. This causes abnormally high internal temperatures, resulting in unstable operation. After long-term operation in extreme environments, generator sets require regular maintenance, cleaning, or replacement. However, existing silent generator sets, to ensure quiet operation, often use an integrated enclosed enclosure structure. The enclosure and internal components, as well as the connections between components, are mostly secured with bolts and welds. During maintenance, operators must use various tools to gradually disassemble multiple components such as the enclosure side panels, internal mounting brackets, and protective covers. This cumbersome and time-consuming disassembly process not only reduces maintenance efficiency but also increases operating costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a silent generator set adapted to high-altitude, cold, and high-temperature environments, solving the problems of easy clogging of the air inlet filter and poor maintenance convenience of existing generator sets.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a silent generator set adapted to high-altitude, cold, and high-temperature environments, comprising a base plate and side plates disposed at both ends of the base plate. An air inlet is provided on the side plate. A slide rail is fixedly connected to the end of the side plate away from the base plate. A moving block is slidably connected within the slide rail. A threaded rod is rotatably connected within the slide rail and threadedly connected to the moving block. A filter screen is fixedly connected within the air inlet. A brush plate is fixedly connected to the end of the moving block near the base plate, with the brush bristles abutting against the filter screen. An adjusting pipe is fixedly connected to the other end of the side plate and communicates with the air inlet. Multiple flaps are evenly rotatably connected within the adjusting pipe. An adjusting groove is provided on the adjusting pipe. A spur gear is fixedly connected to one end of the flap located in the adjusting groove. A toothed plate is slidably connected within the adjusting groove, with the teeth of the spur gear meshing with the teeth of the toothed plate. The movement of the toothed plate causes the flaps to flip.

[0006] Preferably, two tracks are fixedly connected to the upper surface of the base plate, a cross plate is fixedly connected between the two tracks, a rotary motor is fixedly connected to the lower surface of the cross plate, and a pull plate is fixedly connected to the output end of the rotary motor.

[0007] Preferably, two symmetrical sliding grooves are provided on the horizontal plate, and a sliding seat is slidably connected in the sliding groove. The two ends of the pulling plate are rotatably connected to hinge plates, and the hinge plates are rotatably connected to the sliding seats. A pin is fixedly connected to the end of the sliding seat near the track.

[0008] Preferably, one end of the two side plates is fixedly connected to a back plate, the other end of the side plates is provided with a mounting hole, and a heat pipe and a temperature sensor are fixedly connected to the end of the back plate near the power generation device.

[0009] Preferably, a slider is slidably connected within the track, and a support plate is fixedly connected to the ends of two sliders away from the base plate. Shock-absorbing pads are installed on the support plate near the four corners, and a power generation device is fixedly connected to the upper surface of the plurality of shock-absorbing pads.

[0010] Preferably, the two side plates are fixedly connected to a top plate at the ends away from the bottom plate, and an exhaust vent is provided on the top plate, with an air collection box fixedly connected inside the exhaust vent.

[0011] Preferably, the end of the regulating pipe away from the side plate is fixedly connected to an air guide pipe, the air guide pipe is connected to the air collection box, and the output end of the air collection box has two symmetrical placement slots, in which a fan is fixedly connected.

[0012] Preferably, a water tank is fixedly connected to the other end of the back plate, and a heat-conducting pipe passes through the back plate and is connected to the water tank.

[0013] Preferably, a locking plate is inserted into the mounting hole, and a panel is fixedly connected to the end of a plurality of locking plates away from the mounting hole. A mounting groove is provided on the panel, and a sealing ring is fixedly connected in the mounting groove.

[0014] Preferably, a fixing frame is fixedly connected to the end of the side plate away from the adjusting tube, and a plug rod is slidably connected to the fixing frame. A spring is sleeved on the outer wall of the plug rod, and the plug rod is inserted into the locking plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This invention monitors the temperature inside the device using a temperature sensor on the backplate. When the device is detected to be in a low-temperature environment, the toothed plate drives the flap to rotate and close the regulating pipe. The heating device in the water tank heats the circulating water in the heat pipe, ensuring that the device is always at the optimal operating temperature. When a high-temperature state is detected, the toothed plate drives the flap to actively open the regulating pipe to the maximum air intake state. A metal heat collection cover is installed on the side of the air duct near the power generation device to transfer heat to the air duct. The heat is then quickly discharged from the device by the fan rotation, which can improve the adaptability of the device.

[0017] 2. This invention uses a brush plate to remove dust and impurities from the filter screen surface, preventing impurities from clogging the filter screen holes and causing air inlet blockage. Simultaneously, an independently designed heat dissipation duct prevents dust and impurities from entering the device and affecting its heat dissipation. A fan rotating in the opposite direction blows the cleaned dust and impurities away from the filter screen, preventing impurities from clogging the mesh again during air intake. Shock-absorbing pads installed at the four corners of the power generation device reduce noise generated by its vibration. Sound-absorbing cotton on the inner wall of the device absorbs noise generated by the device. An ultra-thin ceramic fiber felt composited around the heat pipe attenuates the slight noise generated by the heat pipe's vibration. Through multiple noise reduction treatments, the noise level during device operation is reduced.

[0018] 3. This invention uses a rotary motor to drive a slide block to move along a slide groove. When the device needs to be repaired, multiple rods can be pulled simultaneously to disengage the rods from the locking plate, allowing the panel to be removed. Then, by pulling the pull plate, two pins can be pulled out of the slide block to release the device from the lock, allowing the generator to be moved out along the track. This allows for quick disassembly of the generator and improves the convenience of maintenance. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] refer to Figures 1-7 The diagram illustrates a silent generator set adapted to high-altitude, cold, and high-temperature environments, comprising a base plate 11 and side plates 4 disposed at both ends of the base plate 11. Specific embodiments are shown below:

[0029] Example 1

[0030] An air inlet 35 is provided on the side plate 4. A slide rail 3 is fixedly connected to the end of the side plate 4 away from the bottom plate 11. A moving block 37 is slidably connected inside the slide rail 3. A threaded rod 36 is rotatably connected inside the slide rail 3, and the threaded rod 36 is threadedly connected to the moving block 37. A filter screen 2 is fixedly connected inside the air inlet 35. A brush plate 38 is fixedly connected to the end of the moving block 37 near the bottom plate 11, and the bristles of the brush plate 38 abut against the filter screen 2. Wind speed sensors pre-installed on both sides of the filter screen 2 monitor the wind speed of the filter screen 2. When an abnormal wind speed is detected, the drive motor matching the threaded rod 36 drives the threaded rod 36 to rotate, thereby cleaning the dust and impurities on the surface of the filter screen 2 and preventing dust and impurities from clogging the mesh of the filter screen 2, which would reduce the air intake of the air inlet 35.

[0031] An adjusting pipe 15 is fixedly connected to the other end of the side plate 4, and the adjusting pipe 15 is connected to the air inlet 35. Multiple flaps 39 are evenly rotatably connected inside the adjusting pipe 15. An adjusting groove 40 is opened on the adjusting pipe 15. A spur gear 42 is fixedly connected to one end of the flap 39 located in the adjusting groove 40. A toothed plate 41 is slidably connected inside the adjusting groove 40, and the teeth of the spur gear 42 mesh with the teeth of the toothed plate 41. The flap 39 is rotated by the movement of the toothed plate 41. A back plate 5 is fixedly connected to one end of both side plates 4. The end of the back plate 5 near the generator 26 is fixed. A heat pipe 24 and a temperature sensor 23 are connected. The ends of the two side plates 4 away from the bottom plate 11 are fixedly connected to the top plate 6. An exhaust port 7 is opened on the top plate 6. An air collection box 22 is fixedly connected inside the exhaust port 7. An air guide pipe 14 is fixedly connected to the end of the regulating pipe 15 away from the side plate 4. The air guide pipe 14 is connected to the air collection box 22. Two placement slots 43 are symmetrically opened at the output end of the air collection box 22. A fan 10 is fixedly connected inside the placement slots 43. A water tank 16 is fixedly connected to the other end of the back plate 5. The heat pipe 24 passes through the back plate 5 and is connected to the water tank 16. The ambient temperature of the power generation device 26 is monitored by temperature sensor 23. When in a high-altitude or cold environment, the processor controls the movement of the toothed plate 41, causing multiple flaps 39 to flip synchronously, thus closing the regulating pipe 15. At this time, the heating rod in the water tank 16 heats the circulating water in the heat pipe 24, increasing the internal temperature of the device. Simultaneously, the fan 10 is turned off to ensure the power generation device 26 operates at a suitable temperature. The heating power of the heating rod in the water tank 16 is automatically adjusted based on the monitoring data from temperature sensor 23. When the device is used in a high-temperature environment, temperature sensor 23 monitors the internal temperature of the device. The controller monitors the temperature and moves the toothed plate 41 according to the monitoring results, adjusts the rotation angle of the flap 39, and thus adjusts the air intake. A metal heat collection cover is installed on the side of the air duct 14 near the power generation device 26 to transfer heat into the air duct 14. The speed of the fan 10 is adjusted synchronously. The water cooling components in the water tank 16 reduce the temperature of the circulating water, thus reducing the temperature inside the device. At the same time, an independent heat dissipation air duct is used to prevent dust and impurities from the outer wall from entering the device. The reverse rotation of the fan 10 blows the dust and impurities cleaned from the filter screen 2 away from its surface, preventing dust and impurities from adhering to the filter screen 2 and causing it to block again during air intake.

[0032] Example 2

[0033] Two rails 12 are fixedly connected to the upper surface of the base plate 11. A horizontal plate 28 is fixedly connected between the two rails 12. A rotary motor 29 is fixedly connected to the lower surface of the horizontal plate 28. A pull plate 30 is fixedly connected to the output end of the rotary motor 29. Two sliding grooves 31 are symmetrically opened on the horizontal plate 28. A slide block 32 is slidably connected in the sliding groove 31. Hinges 33 are rotatably connected to both ends of the pull plate 30, and the hinges 33 are rotatably connected to the slide block 32. The end of the slide block 32 closest to the rail 12 is fixedly connected to... There is a pin 34, and the other end of the side plate 4 has a mounting hole 8. A locking plate 18 is inserted into the mounting hole 8. The ends of multiple locking plates 18 away from the mounting hole 8 are fixedly connected to a panel 1. The panel 1 has a mounting groove 17. A sealing ring 9 is fixedly connected in the mounting groove 17. The end of the side plate 4 away from the adjusting tube 15 is fixedly connected to a fixing bracket 19. A plug rod 20 is slidably connected to the fixing bracket 19. A spring 21 is sleeved on the outer wall of the plug rod 20, and the plug rod 20 is inserted into the locking plate 18.

[0034] The panel 1, side panel 4, back panel 5, top panel 6, and bottom panel 11 together form a sealed structure. The generator 26 has an independent air intake channel and an exhaust channel. The above-mentioned sealed structure will not affect the normal operation of the generator 26. When the generator 26 needs to be removed for maintenance, multiple plug rods 20 are pulled simultaneously to release the plug rods 20 from the locking plate 18, thus completing the disassembly of the panel 1. The rotating motor 29 drives the pulling plate 30 to rotate, so that the pulling plate 30 pulls the slide block 32 and the pin 34 along the slide groove 31, so that the pin 34 is pulled out from the positioning hole of the slider 27, releasing the locking state of the slider 27, thus completing the disassembly of the generator 26. Moving it along the track 12, the generator 26 can be taken out for maintenance, which can greatly improve the convenience of maintenance of the generator 26.

[0035] Example 3

[0036] A slider 27 is slidably connected inside the track 12. A support plate 13 is fixedly connected to the ends of two sliders 27 away from the base plate 11. Shock-absorbing pads 25 are installed near the four corners of the support plate 13. A generator 26 is fixedly connected to the upper surface of multiple shock-absorbing pads 25. Sound insulation cotton is installed on the inner wall of the aforementioned sealed structure. The shock-absorbing pads 25 installed at the four corners of the generator 26 are used to reduce the noise generated by its vibration. The ultra-thin ceramic fiber felt composite on the outside of the air duct 14 can attenuate the slight noise generated by the vibration of the air duct 14. The thickness of the ultra-thin ceramic fiber felt is less than 2 mm, so it does not affect the heat conduction of the air duct 14 while providing sound insulation. A honeycomb sound insulation plate is installed at the end of the flap 39 near the air duct 14. During the rotation of the flap 39, the noise generated inside the device is absorbed and reduced. Through multiple noise reduction treatments, the noise during device operation can be reduced.

[0037] The working principle of this invention is as follows: A sealed structure is formed by the panel 1, side panels 4, back panel 5, top panel 6, and bottom panel 11. Sound insulation cotton is installed on the inner wall of the sealed structure. Shock-absorbing pads 25 are installed at the four corners of the power generation device 26 to reduce noise generated by its vibration. The ultra-thin ceramic fiber felt composite on the outside of the air duct 14 can attenuate the slight noise generated by the vibration of the air duct 14. A honeycomb sound insulation board is installed at one end of the flip plate 39 near the air duct 14, absorbing and reducing noise generated inside the device during the rotation of the flip plate 39. When it is necessary to remove the power generation device 26... During maintenance, multiple insert rods 20 are pulled simultaneously to release them from the locking plate 18. The rotary motor 29 drives the pulling plate 30 to rotate, causing the pulling plate 30 to simultaneously pull the slide block 32 and the pin 34 along the slide groove 31. This allows the pin 34 to be pulled out of the positioning hole in the slider 27 and moved along the track 12 to remove the generator 26 for maintenance. Wind speed sensors pre-installed on both sides of the filter screen 2 monitor the wind speed of the filter screen 2. When an abnormal wind speed is detected, the drive motor of the threaded rod 36 drives the threaded rod 36. The device rotates to clean dust and impurities from the surface of filter 2. In high-altitude, cold environments, the processor controls the movement of the toothed plate 41, causing multiple flaps 39 to flip synchronously, closing the regulating pipe 15. At this time, the heating rod in the water tank 16 heats the circulating water in the heat pipe 24, increasing the internal temperature of the device. Simultaneously, based on the monitoring data from the temperature sensor 23, the heating power of the heating rod in the water tank 16 is automatically adjusted. When the device is used in a high-temperature environment, the temperature sensor 23 monitors the internal temperature, and the controller... Based on the monitoring results, the toothed plate 41 is moved to adjust the rotation angle of the flap 39, thereby adjusting the air intake. A metal heat collection cover is installed on the side of the air duct 14 near the power generation device 26 to transfer heat into the air duct 14. The speed of the fan 10 is adjusted synchronously. The water cooling components of the water tank 16 reduce the temperature of the circulating water. At the same time, an independent heat dissipation air duct is used to prevent dust and impurities from the outer wall from entering the device. The reverse rotation of the fan 10 blows the dust and impurities cleaned from the filter screen 2 away from its surface, preventing dust and impurities from adhering to the filter screen 2.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
