Embodiment 1

[0033] Such as Figure 1-3 As shown, the present embodiment provides a dust suppression spray device 1, including a rotating member 11, a power generating device 12, an electric control valve 13 and a spray assembly 14, the rotating member 11 is connected to the power generating device 12, and the generating device 12 is connected to the above-mentioned The electric control valve 13 is electrically connected, and the output end of the electric control valve 13 is connected with the spray assembly 14 .

[0034] In this embodiment, when in use, the input end of the electric control valve 13 is connected to the infusion pipeline, and the rotating member 11 rotates to drive the power generation device 12 to generate electricity, so that the power generation device 12 generates electric energy, so that the electric control valve 13 obtains an electric signal, and the electric signal makes The electric control valve 13 is opened, so that the liquid in the infusion pipeline enters th...

Embodiment 2

[0036] Such as Figure 1-3 As shown, this embodiment is based on the above-mentioned embodiment 1, and the above-mentioned rotating member 11 is a driving wheel, and the rotating shaft of the above-mentioned driving wheel is connected to the above-mentioned power generation device 12 through transmission.

[0037]In this embodiment, the rotating member 11 is a driving wheel, and the driving wheel has a simple structure. Directly controlling the rotation of the driving wheel can make the generator generate electricity, thereby controlling the opening of the electric control valve 13 to reduce dust.

[0038] Using the driving wheel as the rotating member 11, on the premise of realizing its rotating function, on the one hand, the cost is low, and the operation is simple; on the other hand, the structure is simple, and the overall weight is light, easy to carry, and easy to install.

[0039] In some implementations of this embodiment, an acceleration gear set 111 may be provided b...

Embodiment 3

[0043] Such as Figure 1-3 As shown, this embodiment further includes an energy storage device 16 on the basis of some of the above-mentioned embodiments, and the energy storage device 16 is electrically connected between the above-mentioned power generation device 12 and the above-mentioned electric control valve 13 .

[0044] In this embodiment, the energy storage device 16 can store the electric energy generated by the power generation device 12 in the energy storage device 16, and then the energy storage device 16 will provide an electric signal to the electric control valve 13, so that the electric control valve 13 can be opened, so that During the dust removal process of the device, the excess electric energy generated by driving the generator through the driving wheel will be stored in the energy storage device 16. When the driving device stops rotating and the power generation device 12 stops generating electricity, the energy storage device 16 can still continue to gen...

Abstract

The invention provides a dust-falling spraying device and a dust-falling spraying system for a mine, and relates to the technical field of dust-falling spraying. The dust-falling spraying device comprises a rotating part, a power generation device, an electric control valve and a spraying assembly, wherein the rotating part is in transmission connection with the power generation device, the power generation device is electrically connected with the electric control valve, and the output end of the electric control valve is connected with the spraying assembly. Dust which is generated during operation is effectively settled by using external mechanical energy, and the use and the control are relatively simple. According to the dust-falling spraying system for the mine, under the mine, mechanical energy of a conveying device can be effectively utilized to automatically control the dust-falling spraying device, coal dust or dust which is generated in the conveying process can be settled, the concentration of the coal dust under the mine is reduced, explosion is avoided, and on the other hand, the physical health of workers can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of dust-reducing spraying, in particular to a dust-reducing spraying device and a dust-reducing spraying system for mines. Background technique [0002] In underground mining and blasting mining operations, the fine particles formed by the crushing of coal and rock during the blasting process form coal dust and rock dust respectively. Airborne dust enters the respiratory organs of the human body with human breathing, and the larger dust particles are trapped in the respiratory tract and are easily discharged from the body, while most of the dust with a particle size of less than 5 microns can enter the human lungs and cause various types of pneumoconiosis ; The coal dust generated by the coal seam in most coal mines is explosive. When the coal dust is suspended in the air and reaches a certain concentration, the coal dust can explode under the action of a high-temperature heat source. Existing dust suppress...
