The threaded rod 14 is threadedly connected to the brush plate 13, and the brush plate 13 is in contact with the observation window 4.

[0023] A soundproofing plate cover 2 is fixedly installed on the inner wall of the box body 1 to perform the first soundproofing on the generator set main body 29, and then a sound-absorbing cotton board 3 is fixedly installed on the inner wall of the soundproofing plate cover 2 to perform the second soundproofing on the generator set main body 29. When the generator set main body 29 is working, the sound effect is rebounded by the sound-absorbing cotton board 3 to achieve the soundproofing effect. An observation window 4 is fixedly installed on the outer wall of one side of the box body 1 to observe the operation of the generator set main body 29 in the box body 1. After the device has been used for a long time, a lot of dust is attached to the surface of the observation window 4. The grooves 6 are opened on one side of the opposite surface of the fixed plate 5 fixedly installed on both sides of the outer wall of the observation window 4. The motor 9 fixedly installed at the bottom end of the groove 6 is opened, thereby driving the screw rod 10 fixedly installed at the output end of the motor 9 to rotate, and the slider 8 passes through the top end of the screw rod 10 and is rotatably connected to the top end of the groove 6, so that the screw rod 10 rotates while the screw rod 10 and the slider 8 are screwed together. The slider 8 is connected with the groove, and the slider 8 slides in the groove, thereby driving the slider 8 to reciprocate up and down, so that the long board 11 fixedly installed between the two sliders 8 can reciprocate up and down, so that the brush plate 13 connected in the second groove 12 opened on the side of the long board 11 close to the box body 1 is slidably connected, and the threaded rod 14 threadedly connected to the side of the long board 11 away from the box body 1 is threadedly fixed to the brush plate 13 and the long board 11, so that it drives the brush plate 13 to slide against the surface of the observation window 4, so as to clean the dust on the surface of the observation window 4. When the brush plate 13 needs to be disassembled for cleaning for a long time, the threaded rod 14 threadedly connected to the side of the long board 11 away from the box body 1 is rotated, so that the brush plate 13 slides through the second groove 12 opened on the side of the long board 11 close to the box body 1, so that the brush plate 13 slides out for disassembly, so as to clean and replace the brush plate 13.

[0024] like Figure 1-3 As shown, a hinge 15 is fixedly installed on one side of the box body 1 away from the observation window 4, a metal door 16 is fixedly installed on one side of the hinge 15, a U-shaped block 17 is fixedly installed on one side of the box body 1, a clamping block 18 is fixedly installed on one side of the metal door 16 close to the U-shaped block 17, and a handle is fixedly installed on one side of the metal door 16 close to the clamping block 18, the clamping block 18 is engaged with the U-shaped block 17, and a latch is arranged between the U-shaped block 17 and the clamping block 18, and the latch is pulled out of the U-shaped block 17 and the clamping block 18 by toggling the latch arranged between the U-shaped block 17 and the clamping block 18, thereby pulling the handle fixedly installed on one side of the metal door 16 fixedly installed on one side of the box body 1, so that the metal door 16 is pulled open through the hinge 15, and when pulled open, the clamping block 18 fixedly installed on one side of the metal door 16 is separated from the U-shaped block 17, so that the metal door 16 is pulled open, so that the staff can enter the box body 1 to inspect and repair the generator set main body 29.

[0025] like Figure 4-6 As shown, a connecting groove 19 is provided on one side of the box body 1, and a heat sink 20 is fixedly installed on one side of the connecting groove 19 inside the box body 1, and the heat sink 20 is connected to the connecting groove 19, and a heat sink 21 is fixedly installed inside the connecting groove 19, and heat dissipation holes 22 are provided on the surface of the heat sink 21, and a fixing frame 23 is fixedly installed on the bottom end of the heat sink 20, and an electric fan 24 is fixedly installed on one side of the fixing frame 23, and ventilation holes 25 are provided on one side of the heat sink 20 near the electric fan 24, and the box body 1 is ventilated through the heat dissipation holes 22 provided on the heat sink 21 fixedly installed inside the connecting groove 19 opened on one side of the box body 1, and the electric fan 24 is connected to an external power supply to start the electric fan 24, so that the electric fan 24 rotates and blows air to the ventilation holes 25, so as to cool down the generator set main body 29 in the box body 1, and prevent the generator set main body 29 from being damaged due to excessive temperature caused by long-term use and inability to dissipate heat, thereby damaging the internal components of the generator set main body 29.

[0026] Working principle: When the generator set body 29 is working, the first sound insulation board cover 2 is used to silence the generator set body 29, and then the second sound insulation board 3 is used to silence the generator set body 29. When the generator set body 29 is working, the sound is rebounded by the sound-absorbing cotton board 3 to achieve the effect of sound insulation. When the generator set body 29 generates vibration during operation, the spring 27 in the box body 1 is used to buffer the generator set body 29 to prevent the parts from falling off due to excessive vibration during operation. The operation of the generator set body 29 in the box body 1 is observed through the observation window 4. After the device has been used for a long time, there is a lot of dust attached to the surface of the observation window 4. By turning on the motor 9, the screw rod 10 is driven to rotate, thereby driving the slider 8 to reciprocate up and down, and the long plate 11 reciprocates up and down. The brush plate 13 slides against the surface of the observation window 4, so as to clean the dust on the surface of the observation window 4. When the brush plate 13 needs to be removed for cleaning for a long time, the threaded rod 14 is rotated. The brush plate 13 is thereby slid through the second slide groove 12, so that the brush plate 13 is slid out for disassembly, and the brush plate 13 is cleaned and replaced. When the generator set body 29 is working and generates heat, the box body 1 is ventilated through the heat dissipation holes 22 opened on the box heat dissipation plate 21, and the electric fan 24 is connected to an external power supply, and the electric fan 24 is started to blow air through the ventilation holes 25 inside the heat dissipation box 20, so that the generator set body 29 in the box body 1 is cooled down, so as to prevent the generator set body 29 from being overheated due to long-term use. The heat cannot be dissipated, causing damage to the internal components of the generator set body 29. When the generator set body 29 is to be repaired and inspected, the pin set between the U-shaped block 17 and the card block 18 is toggled, the pin is pulled out of the U-shaped block 17 and the card block 18, and the handle is pulled to open the metal door 16 through the hinge 15. When opening, the card block 18 fixedly installed on one side of the metal door 16 is separated from the U-shaped block 17, thereby opening the metal door 16, making it convenient for staff to enter the box 1 to inspect and repair the generator set body 29.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
