However, although the above method reduces the noise generated during the operation of the diesel generator, the installation of the noise reduction device will make it difficult for the temperature of the diesel generator set to dissipate during operation. After long-term operation, the temperature is high, which may seriously cause damage to the diesel generator set. Summary of the invention

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 A diesel generator with a temperature control function includes a diesel generator body 4, which is installed in a sound insulation device to reduce the noise of the diesel generator body 4. The sound insulation device includes a base 1, and a sound insulation box 2 is installed on the top of the base 1. The diesel generator body 4 is installed in the sound insulation box 2. The outer walls of both sides of the sound insulation box 2 are provided with installation grooves 5, and a plurality of through holes 2 are provided in the installation grooves 5 for heat dissipation.

[0023] The temperature control device includes a heat collecting box 3, which is installed on the top of the sound insulation box 2. Second permanent magnets 16 are fixedly connected to both sides of the inside of the heat collecting box 3. A slide bar 13 is fixedly connected to the top of the second permanent magnet 16. The slide bar 13 is slidably matched with the first permanent magnet 14. A compression spring 15 is sleeved on the slide bar 13 between the first permanent magnet 14 and the second permanent magnet 16. The first permanent magnet 14 and the second permanent magnet 16 attract each other, and the elastic force of the compression spring 15 is less than the magnetic force of the two, causing the compression spring 15 to be compressed.

[0024] Slots 10 are provided on both sides of the collector box 3, and a connecting rod 11 is slidably fitted in the slot 10. One end of the connecting rod 11 is fixedly connected to the first permanent magnet 14, and the other end is fixedly connected to a rack 12. A plurality of rotating shafts 7 are rotatably installed in the mounting groove 5, and the rotating shafts 7 correspond to the through holes 6 one by one. A cover plate 8 is fixedly connected to the rotating shaft 7, and the cover plate 8 can be sealably connected to the through hole 6. A gear 9 is fixedly connected to one end of the rotating shaft 7, and the rack 12 is meshed with the gear 9. The collector box 3 is used to collect the heat generated when the diesel generator 4 is working. When the collector box 3 collects heat, the internal temperature will gradually increase, and then the temperature of the first permanent magnet 14 and the second permanent magnet 16 will gradually increase. As the temperature of the two increases, the magnetic force between the two will gradually decrease. When the magnetic force between the first permanent magnet 14 and the second permanent magnet 16 is less than the elastic force of the compression spring 15, the first permanent magnet 14 moves upward under the elastic force of the compression spring 15, thereby driving the rack 12 to move upward. The upward movement of the rack 12 drives the gear 9 to rotate, and the gear 9 drives the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the cover plate 8 to rotate, thereby making the through hole 6 conductive, and the heat in the heat insulation box 2 is lost from the through hole 6 to control the temperature in the sound insulation box 2 and prevent the temperature in the sound insulation box 2 from being too high.

[0025] Due to the increase of heat in the soundproof box 2, its pressure will also increase. When the through hole 6 is connected, the high-temperature gas in the soundproof box 2 will be discharged from the through hole 6. In order to prevent the airflow from generating noise through 6, a silencer is provided in the soundproof box 2. The silencer includes a shell 17 and a noise reduction pipe 20. The shell 17 is fixedly connected to the inner side walls of the soundproof box 2. The through hole 6 is connected to the shell 17. Sound insulation cotton 18 is provided in the shell 17. A pipe 19 is connected to the shell 17. The pipe 19 is connected to the noise reduction pipe 20. The top of the noise reduction pipe 20 is connected to an air intake pipe 21. The air intake pipe 21 is connected to an air collecting hood 30. A plurality of buffer plates 22 are spaced apart on both sides of the inside of the noise reduction pipe 20. A buffer spring 23 is fixedly connected between two adjacent buffer plates 22. The buffer plate 22 can be slidably fitted in the noise reduction pipe 20. An hourglass-shaped air guide pipe 24 is provided in the noise reduction pipe 20 below the buffer plate 22. When the through hole 6 is opened, the high-temperature gas in the sound insulation box 2 will enter the air intake pipe 21 from the air collecting hood 30. After entering the noise reduction pipe 20, the airflow is affected by the buffer plate 22 and the buffer spring 23 to slow down the flow rate of the airflow and reduce the noise. When passing through the through hole 6, the noise generated will be absorbed by the sound-absorbing cotton 18.

[0026] Guide rods 27 are fixedly connected to both sides of the noise reduction tube 20 below the air guide tube 24, and a slide tube 28 is slidably matched on the guide rod 27. A sound insulation board 25 is fixedly connected to the slide rod 28. A wavy sound absorbing structure 26 is provided on the sound insulation board 25, and a return spring 29 is sleeved on the slide tube 28. When the airflow passes between the sound insulation boards 25, it is affected by the sound absorbing structure 26, and its flow velocity and airflow vibration will be further reduced, thereby further improving the sound reduction function.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
