By arranging the waterproof plate 4 and the drainage grooves 5, the waterproof plate 4 is an anti-seepage material made of high molecular polymer as the basic raw material, which can prevent liquid leakage, and the drainage grooves 5 can facilitate the discharge of rainwater.

[0026] The outer surface of the first fixed frame 301 is slidably connected to the inner wall of the limit frame 2, and the inner wall of the waterproof board 4 is threadedly connected with four bolts 6. The bottom end of each bolt 6 penetrates the waterproof board 4 and extends to the inside of the limit frame 2. By setting the bolts 6, the waterproof board 4 can be easily fixed to the surface of the limit frame 2, so as to stably perform waterproofing work.

[0027] The inner wall of the first fixed frame 301 is fixedly connected with a sound insulation board 304, and the outer surface of each bolt 6 is slidably connected with a gasket 7, and the bottom surface of each gasket 7 is in contact with the upper surface of the waterproof board 4. By providing the gasket 7, a certain protection effect can be played for the waterproof board 4 to avoid damage caused by the squeezing of the bolt 6.

[0028] The inner wall of the first fixed frame 301 is fixedly connected with a sound absorbing plate 305, the inner wall of the limit frame 2 is slidably connected with a support plate 302, and the inner wall of the limit frame 2 is threadedly connected with four threaded wires 10, and the bottom end of each threaded wire 10 passes through the limit frame 2 and extends to the inside of the top body 1. By setting the threaded wires 10, the limit frame 2 can be fixed on the surface of the top body 1, so that it can stably perform the limiting work, thereby improving the stable working effect of the internal device.

[0029] The upper surface of the support plate 302 is in contact with the bottom surface of the first fixed frame 301, and five groups of honeycomb silencers 306 are fixedly connected to the inner wall of the support plate 302. An insulation board 8 is arranged inside the first fixed frame 301, and the outer surface of the insulation board 8 is fixedly connected to the inner wall of the first fixed frame 301. By setting the insulation board 8, the insulation board 8 is a kind of insulation board 8 made of polystyrene material, which is a lightweight insulation material with good thermal insulation performance.

The sound insulation board 304 is firmly fixed. When raindrops hit the waterproof board 4, the sound insulation board 304 can block part of the noise generated by the raindrops hitting the waterproof board 4. At the same time, part of the noise penetrates the sound insulation board 304 and continues to diffuse inward. Under the action of the sound absorbing board 305, part of the noise can be absorbed, thereby reducing the overall intensity of the noise. After the noise is subjected to the first step of silencing treatment, a small amount of noise will enter the honeycomb silencer 306. The noise can be continuously refracted and rebounded inside the honeycomb silencer 306, thereby further reducing the intensity of the noise. At the same time, a small amount of low-intensity noise will be further absorbed by the sound-absorbing cotton 307 after passing through the honeycomb silencer, thereby effectively eliminating the noise and preventing the noise from affecting the people in the room.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
