Description
Technical Field
[0001] This invention relates to the field of diesel generator technology, and in particular to a diesel generator set with noise reduction and vibration damping functions. Background Technology
[0002] Diesel generator sets, as common emergency power supply equipment, are widely used in various scenarios such as construction, field operations, and emergency rescue. In actual use, generator sets generate significant noise and vibration during operation, and continuously generate heat. If heat cannot be dissipated in time, it will affect the normal operation and service life of the unit. Therefore, existing diesel generator sets are usually equipped with sound insulation structures and heat dissipation devices to reduce noise pollution and ensure stable operation of the unit.
[0003] Existing diesel generator sets mostly use simple noise reduction structures through the casing. Although they can block some noise, the noise can easily spread outward through the air intake and exhaust channels, resulting in limited sound insulation. To address the above problems, this invention proposes a diesel generator set with noise reduction and vibration damping functions. Summary of the Invention
[0004] This invention provides a diesel generator set with noise reduction and vibration damping functions, which solves the shortcomings of existing technologies where noise can easily spread outward through the air intake and exhaust channels and the sound insulation effect is limited.
[0005] This invention provides the following technical solution:
[0006] A diesel generator set with noise reduction and vibration damping function includes a soundproof enclosure for mounting the generator set, and air inlets are provided on both sides of the soundproof enclosure for air intake inside the soundproof enclosure;
[0007] The air inlet section includes multiple air inlet pipes and an air diffuser box. The air inlet pipes are bent at right angles and are fixedly inserted through the top side of the soundproof shell with one end open downwards. The air diffuser box is fixed between the inner walls of both sides of the soundproof shell and is located on one side of the soundproof shell. The other end of each air inlet pipe is fixedly connected to the air diffuser box. The inner walls of both the air inlet pipes and the air diffuser box are fixed with sound insulation cotton. Multiple connected air guide frames are fixed on the side of the air diffuser box away from the air inlet pipes.
[0008] The exhaust fan is located at the top of the soundproof enclosure and is used to extract air from inside the enclosure.
[0009] Furthermore, the exhaust unit includes an exhaust pipe fixedly connected to the top of the soundproof shell, a connecting exhaust pipe fixed to one side of the exhaust pipe, a through shaft rotatably connected to one side of the exhaust pipe, and a set of exhaust fan blades fixed to one end of the shaft.
[0010] Furthermore, a motor is fixedly connected to the top of the soundproof shell, and pulleys are fixedly connected to one end of the motor output shaft and the circumference of the rotating shaft. The two pulleys are driven by a belt.
[0011] Furthermore, the top of the soundproof shell is provided with a cooling mechanism for cooling the incoming air. The cooling mechanism includes a cooling shell, which is fixed to the top of the soundproof shell. A sloping surface is provided at the bottom of one end of the cooling shell. The cooling mechanism also includes circulation components provided on both sides of the soundproof shell for circulating cooling water.
[0012] Furthermore, the circulation assembly includes an outlet pipe, a water tank, a water pump, and a water collection pipe. The outlet pipe is fixedly inserted through the top of the soundproof shell and one end is fixedly connected to the cooling shell. The other end of the outlet pipe is located inside the air diffuser box and has multiple connected heat exchange pipes fixed on its side. The water collection pipe is fixedly inserted through the bottom of the air inlet pipe and one side is fixedly connected to multiple heat exchange pipes. The water tank and the water pump are both fixed to the bottom inner wall of the soundproof shell. The bottom of the water collection pipe is fixedly connected to the surface of the water tank. The pump's pumping end is fixedly connected to the water tank. The pump's outlet end is fixedly connected to an inlet pipe. The top of the inlet pipe is fixedly connected to the cooling shell and located above the slope.
[0013] Furthermore, a semiconductor cooler is fixedly installed at the bottom of the slope, with the cooling end of the semiconductor cooler in contact with the slope.
[0014] Furthermore, a duct is fixedly connected to the top of the soundproof shell, the middle sections of the two water pipes are located inside the duct, and an exhaust pipe is fixedly connected to one side of the middle section of the duct, with the exhaust pipe and the exhaust pipe being fixedly connected.
[0015] Furthermore, multiple heat-conducting rings are fixed around the circumference of the water supply pipe, and all the heat-conducting rings are located inside the air duct.
[0016] Furthermore, a through slide rod is slidably connected between the two sides of the cooling shell, and multiple connecting frames are fixed around the circumference of the slide rod. A lever frame is fixedly connected between the connecting frames, and the lever frame contacts the inclined surface. A drive disk is fixedly connected to one end of the rotating shaft, and an eccentrically mounted drive shaft is fixedly connected to one side of the drive disk. A connecting rod is rotatably connected between the drive shaft and the slide rod.
[0017] Furthermore, multiple rubber pads are fixedly connected to the bottom of the soundproof shell.
[0018] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.
[0019] In this invention, by setting up and using a right-angle bent air inlet pipe and a diffuser box with sound insulation cotton fixed on the inner wall, the air inlet path forms a tortuous maze shape. The noise generated by the generator set is physically attenuated by multiple refractions and impacts during propagation. At the same time, the sound insulation cotton absorbs some of the noise, and together with the sound insulation shell, it effectively reduces the overall operating noise and improves the working environment.
[0020] In this invention, by setting and using a semiconductor cooler, a lever frame, and a cooling shell ramp surface, the semiconductor cooler directly cools the ramp surface, and the lever frame reciprocates to move the cooling water flowing along the ramp surface, so that the cooling water is in full contact with the low-temperature ramp surface, which greatly improves the cooling efficiency of the cooling water, provides low-temperature protection for subsequent air cooling, and ensures stable heat dissipation of the generator set.
[0021] In this invention, by setting up and using the air duct, heat conduction ring, air extraction pipe, and air extraction unit together, the air extraction unit draws air from the air duct to form an airflow when exhausting air. The heat conduction ring increases the contact area between the water supply pipe and the air, so that the airflow can quickly carry away the heat of the cooling water in the water supply pipe, thereby achieving initial cooling of the cooling water and improving the overall efficiency of the circulating cooling system.

[0033] Example 1
[0034] Reference Figures 1-6A diesel generator set with noise reduction and vibration damping function includes a soundproof shell 1 for mounting the generator set 4. The generator set 4 is fixedly installed inside the soundproof shell 1 for power generation. In order to reduce the transmission of vibration generated by the generator set 4 to the outside during operation, multiple rubber pads 2 are fixedly connected to the bottom of the soundproof shell 1. The rubber pads 2 are evenly distributed at the four corners and the middle of the bottom of the soundproof shell 1. The rubber pads 2 absorb vibration energy through their own elastic deformation, thereby reducing the vibration amplitude during overall operation.
[0035] Both sides of the soundproof enclosure 1 are equipped with air inlets to introduce cool air into the enclosure, ensuring the heat dissipation needs of the generator set 4 during operation. Each air inlet consists of multiple air inlet pipes 7 and a diffuser box 8. The air inlet pipes 7 have a right-angle bend structure and are fixedly inserted through the top side of the soundproof enclosure 1. During installation, ensure that the connection between the air inlet pipe 7 and the soundproof enclosure 1 is sealed to prevent air leakage or noise leakage. One end of the air inlet pipe 7 is open downwards, and the other end is fixedly connected to the diffuser box 8. The connection is also sealed by welding or flange connection to ensure airtightness. The diffuser box 8 is fixed to the inner walls of both sides of the soundproof enclosure 1. The air inlet pipe 7 and the air diffuser box 8 are both fixed with sound insulation cotton on the inner walls of the air inlet pipe 7 and the air diffuser box 8. The sound insulation cotton is made of high temperature resistant and flame retardant material and is fixed by adhesive. It covers the entire inner wall of the air inlet pipe 7 and the air diffuser box 8. The sound insulation cotton can play a sound insulation role. At the same time, the air inlet path is tortuous and forms a maze. The noise is physically attenuated after multiple refractions and impacts of the baffle, reducing the overall noise. On the side of the air diffuser box 8 away from the air inlet pipe 7, there are multiple connected air guide frames 9. The air guide frames 9 are set up vertically. The position of different air guide frames 9 can be determined according to the different heat-generating parts of the generator set 4, so as to play a targeted heat dissipation role.
[0036] The top of the soundproof shell 1 is provided with an exhaust section for drawing out the air inside the soundproof shell 1 after it has been heated by heat dissipation, forming an air circulation loop. The exhaust section includes an exhaust pipe 18, which is fixedly connected to the top of the soundproof shell 1. An exhaust pipe 19 is fixedly connected to one side of the exhaust pipe 18. The exhaust pipe 19 extends to one side of the soundproof shell 1 to facilitate the exhaust of hot air to a location away from the work area. A through shaft 20 is rotatably connected to one side of the exhaust pipe 18. A set of exhaust fan blades 21 is fixed to one end of the shaft 20. The fan blades 21 are located inside the exhaust pipe 18. The rotation of the fan blades 21 generates airflow to draw out the air inside the soundproof shell 1.
[0037] To drive the rotating shaft 20 to rotate, a motor 24 is fixedly connected to the top of the soundproof shell 1. The motor 24 is a stepper motor with stable speed adjustment capability. One end of the output shaft of the motor 24 and the circumference of the rotating shaft 20 are both fixedly connected to pulleys 30. The two pulleys 30 are on the same horizontal plane and are connected by belt drive. Through the rotation of the output shaft of the motor 24, the rotating shaft 20 is driven to rotate synchronously by the cooperation of the pulleys 30 and the belt, thereby driving the fan blades 21 to rotate to achieve the ventilation operation, thereby dissipating heat inside the soundproof shell 1.
[0038] To improve the heat dissipation effect of generator set 4, a cooling mechanism is provided on the top of the soundproof shell 1 to pre-cool the air entering the soundproof shell 1. The cooling mechanism includes a cooling shell 3, which is fixed on the top of the soundproof shell 1. A ramp 5 is provided at the bottom of one end of the cooling shell 3. The ramp 5 slopes from one end of the cooling shell 3 to the other end to facilitate the flow of coolant along the ramp 5. The cooling mechanism also includes circulation components provided on both sides of the soundproof shell 1 to realize the circulation of cooling water and ensure continuous cooling effect.
[0039] The circulation assembly consists of an outlet pipe 11, a water tank 10, a water pump 14, and a water collection pipe 23. The outlet pipe 11 is fixedly inserted through the top of the soundproof shell 1, with one end fixedly connected to the cooling shell 3 and the other end extending into the air diffuser box 8. Multiple interconnected heat exchange pipes 12 are fixedly attached to the side of the outlet pipe 11 within the air diffuser box 8. The heat exchange pipes 12 are inclined to contact the air entering the air diffuser box 8. The water collection pipe 23 is fixedly inserted through the bottom of the air inlet pipe 7, with one side fixedly connected to the multiple heat exchange pipes 12, for collecting the cooling water after heat exchange. The water tank 10 and the water pump 14 are both fixed to the bottom inner wall of the soundproof shell 1. The water tank 10 is located on one side of the soundproof shell 1 and is used to store cooling water. The water pump 14 is arranged adjacent to the water tank 10. The bottom of the water collection pipe 23 is fixedly connected to the surface of the water tank 10. After heat exchange, the cooling water flows into the water tank 10 through the water collection pipe 23 for storage. The water pump 14 is fixedly connected to the water tank 10 through a pipe. The water pump 14 is fixedly connected to the water inlet pipe 13. The top of the water inlet pipe 13 is fixedly connected to the cooling shell 3, and the connection is located above the slope surface 5. Through the action of the water pump 14, the cooling water in the water tank 10 is drawn into the cooling shell 3 and flows along the slope surface 5 to achieve heat dissipation.
[0040] Example 2
[0041] Reference Figures 1-6Based on Example 1, an improved diesel generator set with noise reduction and vibration damping function is provided. To further improve the cooling effect of the cooling water, a semiconductor cooler 6 is fixedly installed at the bottom of the slope 5. The cooling end of the semiconductor cooler 6 is in close contact with the slope 5. Through the cooling effect of the semiconductor cooler 6, the slope 5 is cooled, thereby cooling the cooling water flowing along the slope 5 and improving the cooling efficiency.
[0042] A duct 15 is fixedly connected to the top of the soundproof shell 1. The duct 15 is horizontally distributed. The middle sections of the two water inlet pipes 13 are inserted into the duct 15. One side of the middle section of the duct 15 is fixedly connected to an exhaust pipe 17. The other end of the exhaust pipe 17 is fixedly connected to an exhaust pipe 18. When the exhaust pipe 19 exhausts air, the air in the duct 15 is drawn in through the exhaust pipe 17, so that air flow is formed in the duct 15. This airflow then cools the water inlet pipes 13 located in the duct 15, achieving a preliminary cooling effect on the cooling water. To improve the heat exchange efficiency between the water inlet pipes 13 and the air, multiple heat-conducting rings 16 are fixed around the circumference of the water inlet pipes 13. The heat-conducting rings 16 are all located in the duct 15. The heat-conducting rings 16 are made of copper and have good thermal conductivity. By increasing the contact area with the air, the preliminary cooling effect is improved.
[0043] A through-type slide rod 28 is slidably connected between the two sides of the cooling shell 3. A sliding sleeve is provided at the connection between the slide rod 28 and the cooling shell 3 to reduce friction during sliding. Multiple connecting brackets 29 are fixed around the circumference of the slide rod 28 and are evenly distributed along the length of the slide rod 28. A lever bracket 22 is fixedly connected between the connecting brackets 29. The lever bracket 22 contacts the inclined surface 5 inside the cooling shell 3. A drive disk 25 is fixedly connected to one end of the rotating shaft 20. An eccentrically mounted drive shaft 26 is fixedly connected to one side of the drive disk 25. The drive shaft 26 is rotatably connected to the slide rod 28. When the rotating shaft 20 rotates, the connecting rod 27 drives the drive disk 25 to rotate synchronously. When the drive disk 25 rotates, it drives the connecting rod 27 to move through the eccentrically set drive shaft 26. The connecting rod 27 then drives the slide rod 28 to move back and forth between the two sides of the cooling shell 3. When the slide rod 28 moves, it drives the paddle frame 22 to move back and forth synchronously through the connecting frame 29. During the movement, the paddle frame 22 paddles the cooling water flowing along the slope surface 5, so that the cooling water can fully contact the slope surface 5, avoid local accumulation of cooling water and affect the cooling effect, and further improve the cooling efficiency of the cooling water.
[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of generator set 4, semiconductor cooler 6, motor 24 and water pump 14 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0045] The working principle and usage process of this technical solution are as follows: In this invention, a controller is set on the outside of the soundproof shell and a temperature sensor (not shown in the figure) is set inside. The controller adopts a PLC controller. The output terminal of the controller is electrically connected to the motor 24, the water pump 14 and the semiconductor cooler 6 respectively. When in use, the diesel generator set 4 inside the soundproof shell 1 is responsible for generating electricity. During use, the motor 24 is started. The motor 24 drives the shaft 20 to rotate through the pulley 30 and the belt. The shaft 20 drives the fan blade 21 to rotate. The fan blade 21 draws air from inside the soundproof shell 1. The outside air enters the air diffuser box 8 through the air inlet pipe 7 and then enters the soundproof shell 1, thereby cooling the generator set 4. Since the air inlet pipe 7 and the air diffuser box 8 are both fixed with sound insulation cotton, they can achieve the effect of sound insulation. At the same time, the air inlet path is tortuous and forms a maze shape. The noise is physically attenuated after multiple refractions and impacts of the baffle, reducing the overall noise.
[0046] To improve the cooling effect, during operation, the water pump 14 is started, and the water pump 14 draws coolant from the water storage tank 10. The coolant enters the cooling shell 3 through the water inlet pipe 13, flows along the slope surface 5 to dissipate heat, and then enters the heat exchange tube 12 through the water outlet pipe 11, thereby cooling the air entering the air diffuser box 8 and improving the heat dissipation effect of the generator set 4. Finally, the cooling water falls into the water storage tank 10 through the water collection pipe 23.
[0047] When the cooling water dissipates heat, the semiconductor cooler 6 can be activated to cool the cooling water passing through the slope 5. When the rotating shaft 20 rotates, the drive disc 25 drives the drive shaft 26 to rotate. The drive shaft 26 drives the slide bar 28 to move back and forth through the connecting rod 27. The slide bar 28 drives the paddle frame 22 to move through the connecting frame 29. The paddle frame 22 paddles the cooling water so that the cooling water can fully contact the slope 5 and improve the cooling effect.
[0048] When exhausting air, the exhaust duct 19 also draws air from the air guide duct 15 through the air extraction duct 17, thereby causing air to circulate and achieving the effect of initially cooling the cooling water in the water collection duct 23.
[0049] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
