One end of the water cylinder 4 is fixedly connected with a connecting pipe 5. Inside the water cylinder 4, there are several spray pipes 6 and several straight pipes 7 fixedly connected. The spray pipes 6 and the straight pipes 7 are staggered and distributed on one side of the water cylinder 4. On the outer surface of the support rod 1, there is a dust collection net 8. On the outer surface of the support rod 1, there is a cleaning device 2. The cleaning device 2 includes a sliding rod 22 and an H-shaped rod 27. At the top of the sliding rod 22, there are several semi-circular blocks 23 fixedly connected. The semi-circular blocks 23 are linearly distributed on one side of the top of the sliding rod 22. One side of the semi-circular block 23 is attached to one side of the water cylinder 4. On one side of the support rod 1, there is a screw rod 24 rotatably connected. The outer surface of the screw rod 24 is threadedly connected with the inner wall on one side of the sliding rod 22. On the outer surface of the support rod 1, there is a chute 21 and two rectangular grooves 26. The outer surface of the sliding rod 22 slides inside the inner wall of the chute 21. On one side of the top of the support rod 1, there are two magnetic blocks 25 fixedly connected. The H-shaped rod 27 is made of stainless steel material that can be adsorbed by a magnet. On both sides of the inner wall of the H-shaped rod 27, there are several hard brushes 28. The two ends of the H-shaped rod 27 slide inside the inner walls of the two rectangular grooves 26 respectively. By setting the semi-circular blocks 23, when using the dust-proof device, the outer surface of the H-shaped rod 27 contacts the magnetic block 25 on one side of the support rod 1 and is magnetically attracted to fix the H-shaped rod 27 on one side of the top of the support rod 1. Connect the water supply pipeline to the connecting pipe 5 to make water enter the inside of the water cylinder 4. Rotate the screw rod 24 to control the sliding rod 22 to move on the outer surface of the screw rod 24 and the inner wall of the chute 21, and adjust the horizontal position of the sliding rod 22 so that the semi-circular blocks 23 at the top of the sliding rod 22 are located outside each straight pipe 7 on the outer surface of the water cylinder 4 to seal the outside of the straight pipe 7. Through the action of external equipment, the water inside the water cylinder 4 is sprayed out through the spray pipes 6 to collect the dust in the air on the surface of the dust collection net 8. When it is necessary to clean the dust collection net 8, rotate the screw rod 24 to control the sliding rod 22 to move so that the semi-circular blocks 23 on the outer surface of the sliding rod 22 are located outside each spray pipe 6 on the outer surface of the water cylinder 4 to seal the outside of the spray pipe 6. Subsequently, the water inside the water cylinder 4 will flow vertically downward through the straight pipes 7. Then, pull the H-shaped rod 27 to control the H-shaped rod 27 to slide downward inside the inner wall of the rectangular groove 26, and scrape off the wet dust on the surface of the dust collection net 8 through the hard brushes 28 on both sides of the inner wall of the H-shaped rod 27 to clean the surface of the dust collection net 8, as much as possible to avoid the dust blocking the holes on the surface of the dust collection net 8 and affecting the dust collection effect of the dust collection net 8. By setting the cleaning device 2, by adjusting the position of the semi-circular blocks 23, the water inside the water cylinder 4 flows vertically downward, and then by pulling the H-shaped rod 27 to slide inside the inner wall of the rectangular groove 26 and using the hard brushes 28 to scrape off the wet dust on the surface of the dust collection net 8 to clean the surface of the dust collection net 8, as much as possible to avoid the dust blocking the holes on the surface of the dust collection net 8 and affecting the dust collection effect of the dust collection net 8.

When the side of the semicircular block 23 provided with the rubber semicircular sheet 29 is attached to the outer side of the water cylinder 4 to seal the straight pipe 7 or the nozzle 6, the sealing effect is better and it is not easy to leak. The end of the screw rod 24 away from the frame rod 1 is fixedly connected with a disc 210, and one side of the disc 210 is rotatably connected with a grip rod 211. Holding the outer surface of the grip rod 211 to push the disc 210 can more conveniently control the rotation of the screw rod 24 to adjust the position of the sliding rod 22.

[0031] Reference Figures 2-4 As shown, in the present embodiment: a positioning rod 212 is fixedly connected to one side of the frame rod 1, and one end of the sliding rod 22 slides on one side of the positioning rod 212. When the screw rod 24 is rotated to control the movement of the sliding rod 22, the end of the sliding rod 22 away from the slide groove 21 will slide on one side of the positioning rod 212. The positioning rod 212 can further limit the angle between the sliding rod 22 and the frame rod 1 to avoid shaking of the sliding rod 22 when moving. A pull rope 213 is fixedly connected to the bottom end of the H-shaped rod 27. The pull rope 213 is a rope with a certain elasticity. When the H-shaped rod 27 needs to be used to clean the surface of the dust collecting net 8, the pull rope 213 can be pulled to more conveniently pull the H-shaped rod 27 from one side of the magnetic block 25.
