Embodiment Construction

[0027] Wherein, the water pipe 13 is provided with a water valve 131, and the air pipe 12 is provided with an air pipe spring switch 121. Specifically, the air pipe spring switch 121 includes a handle switch 1211, a spring 1212 and a pull rod 1213. The handle switch 1211 is an existing The switch for controlling the on-off of the air pipe 12, through the improvement of the handle switch 1211, a pull rod 1213 can be hinged on the air pipe 12, and the spring 1212 is connected between the pull rod 1213 and the air pipe 12. At this time, due to the existence of the spring 1212 If you want to conduct the air duct 12 through the handle switch 1211, you must first overcome the tension of the spring 1212 so that the pull rod 1213 is in a horizontal position, and then drive the handle switch 1211 to guide the air duct by applying a downward force to the pull rod 1213 12, that is, the air duct spring switch 121 conducts the air duct 12; when the downward force applied to the pull rod 121...

Abstract

The invention provides a compressed-air automatic spraying device and system. The automatic spraying device comprises a spray head, an air pipe, a water pipe and a water storage device, wherein, the water storage device is respectively connected with the air pipe, the water pipe and the spray head; the water pipe is equipped with a water valve; the air pipe is equipped with an air pipe spring switch; and the air pipe spring switch is connected to the outer wall of the water storage device through a rope. The compressed-air automatic spraying device and system provided by the invention have the advantages of overcoming the defect of the prior art that gas explosion is easily caused when an electric control automatic spraying device or an acoustic control automatic spraying device is applied to a working environment of a coal mine with higher gas content, and achieving the purpose of regularly and safely performing automatic spray by virtue of compressed air.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a compressed air automatic spraying device and system. Background technique [0002] For the special working environment of coal mine underground, the construction progress is often affected due to the large amount of dust, so the spray device which plays the role of dust prevention is indispensable. At present, there are multiple spraying devices underground in coal mines, and multiple spraying devices can form a spraying system. However, since each spraying device needs to be manually opened and closed, and there are a large number of spraying devices, if all of them are manually operated, it will take a lot of time. manpower and time. [0003] In the prior art, the automatic spraying device can effectively save manpower and time, but since the automatic spraying device mostly relies on the electric control or sound control system, when the electric control or sound ...
