[0029] Working principle:
[0030] When using the utility model, during the installation process, the protective ring 2 is fixed by the fixing block 1, the circular ring 8 clamps the third groove 21 on the fixing ring 22 and is fixed by the bolt 9, the water tank body 4 is fixed at the top, and the upper end of the support rod 24 supports the water tank body 4, and the lower end is fixed on the ground. Before the underground mining work starts, water is slowly injected into the water tank body 4 through the water injection pipe 3, the electric slide rail 20 drives the sliding block 23, and the sliding block 23 moves the mobile sprayer 19 through the extension block 12. At the same time, the second water pipe 6 located at the upper end of the extension block 12 moves at the same time, and the second water pipe 6 drives the lubrication block 402 and the water tank inner shell 403 to move at a 40-degree angle every 20 seconds to spray water mist. At the same time, the motor 13 drives the long plate 14, and the long plate 14 drives the fixed cylinder 15 to move. As the two fixed cylinders 15 rotate, the long cloth strip 16 located between the two fixed cylinders 15 also rotates. Under the action of the water mist, the long cloth strip 16 becomes moist, which greatly improves its ability to absorb dust, thereby further removing dust. When underground mining begins, smoke and dust gradually rise under the action of the mining machine. After the dust sensor 10 senses the dust, it sends a signal to control the electric slide rail 20 to move the mobile sprayer 19 to the designated location for sensing the smoke and spray water to reduce dust until the dust sensor 10 has no induction. When the mining work is carried out on a large scale, most of the dust sensors 10 send signals, at which time the mobile sprayer 19 stops working, and all the water mist sprayers 11 located under the ring 8 start working to reduce dust until the dust sensor 10 senses and disappears.
