The absorption component includes a plurality of connecting pipes 12 connected to the lower side of the air collecting pipe body 1, the lower side of the plurality of connecting pipes 12 is connected to a dust adsorption box 13, the inner bottom wall of the dust adsorption box 13 is covered with a water body 14, and the front end surface of the upper side of the dust adsorption box 13 is inlaid with an air intake fan 16.

[0023] Among them, the upper side of the first rotating shaft 2 passes through the left side of the air collecting pipe body 1 and extends to the outside, the outer wall of the top of the first rotating shaft 2 is fixedly sleeved with a handle, and the outer wall of the right side of the second rotating shaft 6 is fixedly sleeved with a first bearing 11, and the inner walls of the lower sides of the two support frames 5 are rotatably sleeved with second bearings, and the inner wall on the right side of the first bearing 11 is fixedly sleeved with the inner wall of the exhaust duct of the exhaust fan 10, and multiple exhaust holes 7 are arranged horizontally and equidistantly, and multiple air holes are opened on the front and rear opposite surfaces of the lower baffle plate 9, and the multiple air holes are connected to the connecting pipe 12. The front end face of the dust adsorption box 13 is inlaid with two observation windows 17, and the two observation windows 17 are tempered glass. The surface of the suction fan 16 close to the dust adsorption box 13 is bolted with a dustproof net 15, and the left and right sides of the dust adsorption box 13 are respectively connected with a water injection pipe and a drainage pipe.

[0024] It should be noted that the water inlet pipe and the drain pipe on the left and right sides of the dust adsorption box 13 can drain and inject water to the water body 14 inside the dust adsorption box 13 at any time. The upper end of the water body 14 and the dust adsorption situation can be observed in conjunction with the observation window 17, which is convenient for the subsequent water injection and drainage. When not in use, sealing covers are required to be used to cover the inside of the water inlet pipe and the drain pipe respectively. When the water body 14 is injected, it cannot be higher than the bottom of the dustproof net 15 to avoid the water body 14 from damaging the internal parts of the intake fan 16.

[0025] The working principle of the above embodiment is:

[0026] The first rotating shaft 2 utilizes the meshing of the first bevel gear 3 and the second bevel gear 4 to drive the second rotating shaft 6 to rotate in a circular shape inside the air collecting pipe body 1 to clean and absorb the dust attached to the inner wall of the air collecting pipe body 1. During the rotation of the second rotating shaft 6, the first bearing 11 on the right side can prevent the exhaust pipe of the exhaust fan 10 from rotating synchronously. When the brush 8 passes through the surface of the baffle 9 respectively, the baffle 9 can resist the brush 8 and separate the brush 8 from one side of the baffle 9 with the continuous rotation force. At the same time, the brush 8 will also shake to separate the dust on the surface and let it fall naturally. In order to improve the separation of dust on the surface of the brush 8, it is also necessary to use the exhaust fan 10 to generate Wind energy is discharged into the second rotating shaft 6 and discharged from the exhaust hole 7 to the outer side of the brush 8 to improve the dust separation efficiency. At this time, the suction fan 16 needs to be turned on. The suction force generated by the suction fan 16 passes through the connecting pipe 12 from the air holes opened on the surface of the lower baffle 9, and absorbs the suction force generated by the dust and naturally falls into the water body 14 inside the dust adsorption box 13 or the surface of the dustproof net 15. When the suction fan 16 is turned off, the dust naturally falls to the upper surface of the water body 14, thereby increasing the overall weight of the dust. Observe the observation window 17 at any time to check the dust situation. When a lot of dust is collected, the water body 14 needs to be discharged and new water body 14 needs to be injected.
