The water mist sprayed by the atomizing nozzle 42 is used to entrain the dust, thereby achieving a dust prevention effect; even if the water mist is blown by the wind, the water mist can still activate the effect of entraining dust, thereby reducing the radiation of mine dust to the surrounding area.

[0021] Furthermore, the windward plate 31 is slidably installed on the slide groove 32, and the windward plate 31 can be fixed on the slide groove 32; the sliding installation of the windward plate 31 allows the windward plate 31 to be fine-tuned or adaptively adjusted according to the direction and intensity of the wind; ensuring that no matter how the wind direction changes, the adjusted windward plate 31 can effectively capture the wind force and drive the mounting base 2 and the water spray assembly to rotate, so that the atomizing nozzle 42 is always aligned with the wind flow, thereby improving the dust prevention effect.

[0022] Preferably, both the slide groove 32 and the windward plate 31 are provided with mounting holes 33; and the slide groove 32 is provided with a plurality of mounting holes 33; bolts 34 are passed through the slide groove 32 and the mounting holes 33 of the windward plate 31 to fix the slide groove 32 and the windward plate 31 together; the mounting holes 33 are used to adjust the position of the windward plate 31 in the slide groove 32, and the bolts 34 are used to fix the windward plate 31 in the slide groove 32.

[0023] Furthermore, the support arm 41 is hinged to the mounting base 2; thus, even if the device is installed in various places in the mine at different heights, it can still face the operation center.
