[0002] One ventilation and three preventions is the abbreviation of several important technologies involved in coal mine safety production. "One ventilation" refers to mine ventilation, and "three preventions" refer to gas prevention and control, coal dust prevention and control, and mine fire prevention and control. At present, during coal mining, a large amount of fine dust will be generated in the underground working environment. These dusts will cause serious pollution to the working environment. Therefore, it is necessary to set up various spray facilities underground. The spray facilities can spray water mist to capture the dust in the environment and achieve the purpose of reducing dust. However, the current spray facilities have a short spraying distance, the sprayed water mist and dust have a short combination time, and most of the spray heights are fixed, which makes it inconvenient to spray at different heights.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0020] A dust prevention and control wind and water mixed spray, comprising a fixed pole 1, a forward and reverse motor 101 is installed on the top of the fixed pole 1, the driving end of the forward and reverse motor 101 passes through the interior of the fixed pole 1 and is connected to a rotating screw 102, the outer side of the rotating screw 102 is threadedly connected to a screw slide 103, and the front of the screw slide 103 is connected to a spraying main pipe 2;

[0021] Side mounting plates are installed on the left and right sides of the fixed pole 1, and assembly through holes are symmetrically opened inside the side mounting plates. Both ends of the rotating screw rod 102 are rotatably connected to the inside of the fixed pole 1 through bearing seats. A slide groove extending along the height direction of the fixed pole 1 is opened on the front side of the fixed pole 1, and the connection between the screw rod slide 103 and the slide groove is a sliding connection.

[0022] In this embodiment, please refer to Figure 2 The left end of the rear side of the spray main pipe 2 is connected to a water hose 201, and a water valve 202 is installed in the middle section of the water hose 201. The front side of the spray main pipe 2 is connected to multiple groups of spray branches 203 with the same intervals, and the front end of each group of spray branches 203 is connected to an atomizing nozzle 204. The top of the atomizing nozzle 204 is connected to a fixed support plate 205, and a wind cover 206 is installed on the top of the fixed support plate 205. A blower fan 207 is installed at the rear end of the wind cover 206. The right side of the fixed support plate 205 is connected to a side connecting frame 208, and a dust concentration detection sensor 209 is installed on the front side of the side connecting frame 208;

[0023] A control switch is installed on the outer side of the fixed pole 1, and the control switch is connected to the forward and reverse motor 101, the water valve 202, the blowing fan 207, and the dust concentration detection sensor 209 through wires, and the connection method is electrical connection. The wind hood 206 is installed above the atomizing nozzle 204 in an inclined state.

[0024] The working process of the utility model is as follows: the height of the dust distribution can be detected under the detection of the dust concentration detection sensor 209, and then the height of the spray main pipe 2 is adjusted according to the place where the dust gathers, and the forward and reverse motors 101 are started to drive the rotation of the rotating screw 102, so that the screw slide 103 moves up and down.
