[0028] A limit block 12 is fixedly installed on the bottom of the inner wall of the mounting frame 9, and the limit block 12 is slidably connected to the dustproof net 11. A first spring clamp 13 is installed on the top of the mounting frame 9, and an L-shaped plate 14 is installed on the first spring clamp 13. A positioning hole 15 is opened on the dustproof net 11, and the positioning hole 15 is adapted to the L-shaped plate 14. The dustproof net 11 is limited by the L-shaped plate 14 to ensure that it does not move. The limiting operation is relatively quick and also facilitates subsequent disassembly operations.

The power connection method of each electrical device is an existing mature technology, which is a well-known technology for people in this field and will not be described in detail here.

[0035] When the diesel generator set body 2 is in use, the vibration generated by the operation of the diesel generator set body 2 is absorbed and the reaction force is slowed down by the shock absorber 4 and the seismic isolation pad 3, so as to reduce the impact of the reaction force on the diesel generator set body 2, thereby performing a shock reduction operation on it. While reducing shock, the diesel generator set body 2 can also achieve noise reduction. At the same time, due to the characteristics of its material, the buffer sponge 5 can effectively absorb the elastic force transmitted by the shock absorber 4, thereby playing a role in shock reduction and buffering, thereby improving the shock reduction and noise reduction effect of the diesel generator set body 2. At the same time, the sound-absorbing sponge 7 can perform noise reduction on the diesel generator set body 2.

At the same time, the dustproof net 11 intercepts external dust to ensure that it will not be discharged into the sound insulation box 6. When it is necessary to clean the dustproof net 11, first operate the first spring clamp 13 so that the first spring clamp 13 drives the L-shaped plate 14 to slide, so that the L-shaped plate 14 slides away from the positioning port 15, and then the dustproof net 11 can be removed. Then, operate the second spring clamp 16 so that the second spring clamp 16 drives the limit frame 17 to slide, so that the limit frame 17 slides away from the dustproof net 11, and then the dustproof net 11 can be removed for cleaning.
