For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] Example:

[0038] Reference Figure 1-6The utility model provides a coal mine dust reduction device: comprising a water storage tank 1, a first installation bin 2 and a second installation bin 3 arranged on the top of the water storage tank 1, the first installation bin 2 and the second installation bin 3 are both provided with a heat dissipation mesh port 4 on their sides, a water pump 5 is installed on the inner wall of the first installation bin 2, a water inlet of the water pump 5 is fixedly connected to a water pump pipe 6, one end of the water pump pipe 6 is fixedly connected to a telescopic pipe 7, one end of the telescopic pipe 7 is fixedly connected to a moving pipe 8, a surface of the moving pipe 8 is fixedly connected to a matching wheel 9, and the moving pipe 8 is fixedly connected to a matching wheel 9. A filter head 10 is fixedly connected to one end, a connecting plate 11 fixedly connected to the water tank 1 is fixedly connected to the surface of the water pump 6, a movable plate 12 is slidably connected to the side of the water tank 1 and located below the connecting plate 11, a guide rod 13 slidably connected to the movable plate 12 is fixedly connected to the center of the lower surface of the connecting plate 11, a spring 14 is provided on the surface of the guide rod 13 located between the movable plate 12 and the connecting plate 11, an anti-slip plate 15 is fixedly connected to one end of the guide rod 13, and a drain pipe 27 is fixedly connected to the water outlet of the water pump 5. The bottom inner wall of the water storage tank 1 is fixedly connected with a filter plate 28, and one end of the drainage pipe 27 is connected to the bottom of the filter plate 28. The way to reduce dust in the coal mine is to spray water, so there is often water accumulation on the underground road surface. The water storage tank 1 is moved to the water accumulation position, and after the matching wheel 9 abuts against the flat ground, the normal state of the spring 14 is in a compressed state. When the matching wheel 9 moves on the underground road surface and encounters potholes and bumps, the moving pipe 8 drives the moving plate 12 to slide up and down, thereby causing the spring 14 to deform, and the telescopic tube 7 is extended and retracted to cooperate, so that The movable pipe 8 is not easy to collide with the underground road surface, and at the same time, the matching wheel 9 can always fit with the underground road surface, so that the movable pipe 8 can be close to the underground road surface. After reaching the water accumulation position, the water pump 5 is started. The water pump 5 uses the filter head 10, the movable pipe 8, the telescopic tube 7, and the water pumping pipe 6 to pump water, and the pumped water is discharged into the bottom of the filter plate 28 through the drain pipe 27. The filter head 10 filters the water, which is not easy to absorb debris to damage the water pump 5. The filter plate 28 blocks it to reduce the impurities entering the top of the filter plate 28.

[0039] A spray pump 16 is fixedly connected to the inner wall of the second installation bin 3, a water supply pipe 18 is fixedly connected to the water inlet of the spray pump 16, a branch pipe 17 with an electromagnetic valve arranged inside is fixedly connected to the surface of the water supply pipe 18, a flange 19 is fixedly connected to one end of the branch pipe 17, a hose 20 is fixedly connected to the water outlet of the spray pump 16, a wear-resistant layer is arranged on the surface of the hose 20, a water guide seat 21 is fixedly connected to one end of the hose 20, a water distribution pipe 22 is fixedly connected to the surface of the water distribution pipe 22, atomizing nozzles 23 distributed at equal intervals are fixedly connected to the surface of the water storage tank 1, and a mounting frame 24 is fixedly connected to the upper surface of the water storage tank 1 A waterproof motor 25 is fixedly connected to the surface of the mounting frame 24, and a rotating rod 26 fixedly connected to the water distribution pipe 22 is rotatably connected to the inner wall of the mounting frame 24. The output end of the waterproof motor 25 is fixedly connected to the rotating rod 26. In the normal state, the solenoid valve inside the branch pipe 17 is closed, and the spray pump 16 draws water from the water storage tank 1 through the water supply pipe 18. The spray pump 16 then sprays the water from the atomizing nozzle 23 through the hose 20, the water guide seat 21 and the water distribution pipe 22 to increase the humidity inside the mine. The water vapor in the mine gathers around the dust particles, which increases the mass and diameter of the dust particles, which is conducive to the collision between the dust particles. When dust particles collide with each other, the rebound force is reduced due to the water vapor surrounding the surface, and the dust particles will gradually settle down and fall. The waterproof motor 25 intermittently rotates forward and reverse, so that the water guide seat 21 drives the water distribution pipe 22 to rotate, and then the atomizing nozzle 23 swings up and down. Compared with the spraying area of ​​the fixed atomizing nozzle 23, the coverage area generated by the swinging atomizing nozzle 23 when spraying water is larger. Water is added to the inside of the water storage tank 1 through the branch pipe 17, and the water supply pipe is connected through the flange 19.

[0040] Working principle: The spray pump 16 draws water from the water tank 1 through the water supply pipe 18, and then sprays the water from the atomizing nozzle 23 through the hose 20, the water guide seat 21 and the water distribution pipe 22 to increase the humidity inside the mine. The water vapor in the mine gathers around the dust particles, increasing the mass and diameter of the dust particles, which is conducive to the collision between the dust particles. When dust particles collide with each other, due to the water vapor surrounding the surface, the rebound force is reduced, and the dust particles will gradually settle down to reduce dust. When there is a lot of water on the underground road surface, the water storage tank 1 is moved to the water accumulation position. After the matching wheel 9 abuts against the flat ground, the normal state of the spring 14 is in a compressed state. When the matching wheel 9 moves on the underground road surface and encounters potholes and bumps, the moving pipe 8 drives the moving plate 12 to slide up and down, thereby causing the spring 14 to deform, and the telescopic tube 7 is telescoped to cooperate, so that the moving pipe 8 is not easy to collide with the underground road surface. At the same time, the matching wheel 9 can always fit with the underground road surface, so that the moving pipe 8 can be close to the underground road surface. After reaching the water accumulation position, the water pump 5 is started. The water pump 5 uses the filter head 10, the moving pipe 8, the telescopic pipe 7, and the water pumping pipe 6 to pump water, and the pumped water is discharged into the bottom of the filter plate 28 through the drain pipe 27. The filter head 10 filters the water, which is not easy to inhale large objects to damage the water pump 5. The filter plate 28 is blocked to reduce impurities entering the top of the filter plate 28.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
