An electronically controlled linkage spraying device

Abstract

The invention belongs to the technical field of underground recovery accessories, and particularly relates to an electronic control linkage sprayer. The electronic control linkage sprayer comprises ashell, an external connection bolt, a switch shell and a switch; the left side wall of the shell is in threaded connection with the external connection bolt, the right side wall of the shell is fixedly connected to the switch shell through screws, the right side wall of an inner cavity of the switch shell is fixedly connected to the switch through screws, and the right side wall of the inner cavity of the outer shell is fixedly connected with an electronic communicating device through screws. According to the electronic control linkage sprayer, accessories are combined to be used, and the electronic control linkage sprayer is formed by modifying an electronic control water spray valve and an interlocking contact in the switch. When the device is turned on, a contactor in the switch moves to drive the interlocking contact to close, the water spray valve is automatically opened after a loop is formed and sprays water, a manual button is used in a matched manner to achieve active and electric dual-way operation, the mist spraying effect is achieved, meanwhile, labor cost input and material cost investment can be reduced every year, the overall constructing cost is effectively reduced,the structure is simple, and implementation is easy.

Description

technical field [0001] The invention relates to the technical field of underground mining accessories, in particular to an electronically controlled linkage spraying device. Background technique [0002] A complete set of switches that are used to connect and break the normal current of the carrying line in underground coal mines, and can connect and break the carrying abnormal current within a certain period of time under specified abnormal circuit conditions (such as short circuit), and have obvious fractures in the primary circuit device. It is generally used as a main distribution switch, feed-out switch or branch switch in the power grid with a rated voltage of 1140V and below, and can also control large-capacity motors to start infrequently. [0003] Among them, underground mining is a step in mining. [0004] Spraying devices are installed at the front, rear, reloading machine, and belt conveyor reloading point of the underground recovery work. After using the autom...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of electronically controlled linkage type spraying device, to solve the problem that the front and back slides, reloading machine, and belt conveyor reloading points of the underground recovery work proposed in the above-mentioned background technology are all equipped with spraying devices. , although the automation is realized in the use effect, the vibration and loss of the internal parts of the sensor lead to a very high failure rate, which brings a lot of manual investment to the maintenance work, and the cost of the internal electrical components is also extremely expensive, and the overall economic waste is large, and only Relying on electric drive, in an emergency, the linkage of the device cannot be realized, which reduces the flexibility of operation
