Description
Technical field
The utility model relates to a kind of water curtain control device, is specifically related to a kind of underground coal mine induction type self-purging water curtain control device.
Background technology
Down-hole mining work plane, main product dirt operation is coal cutting, a large amount of afloat coal dust and rock dirt is there is in underground coal mine work plane air, serious harm is caused to the personal safety of underground labour, therefore driving face air entering and returning lane, the main large lane of air intake and driving face all increase and are provided with the distinguished and admirable water curtain of purification, and effectively reduce mine dust concentration, driving face normal condition needs twice water curtain, together work plane about 30 meters, together after 50 meters.The water curtain at 50 meters of at work, because away from work plane, is inconvenient to manage, and often occurs the situation violating the regulations of not boiling water curtain.
Utility model content
The utility model overcomes the deficiency that prior art exists, and it is simple, convenient that technical problem to be solved there is provided a kind of structure, automatically controls, avoids the underground coal mine induction type self-purging water curtain control device of violation operation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of underground coal mine induction type self-purging water curtain control device, comprise: the static pressure water pipe being arranged on down-hole, 127V power line and cables of heading machine, described static pressure water pipe is communicated with bypass duct, the outlet of described bypass duct is connected with atomization water curtain, described bypass duct is provided with electromagnetic valve, described cables of heading machine is provided with start-stop sensor, described electromagnetic valve is connected with explosion-proof electric control box respectively with start-stop sensor, the power input of described explosion-proof electric control box is connected with the junction box on 127V power line.
Preferably, described bypass duct is also provided with stop valve and strainer, described stop valve and strainer are all positioned at the front end of electromagnetic valve.
The utility model structure is simple, easy to use, start-stop sensor, electromagnetic valve is adopted to realize automatically controlling, start-stop sensor detects the electric current of cables of heading machine, the generation current when development machine starts, and start-stop sensor passes signal is to explosion-proof electric control box, explosion-proof electric control box controls to open electromagnetic valve, realize water mist spray, simple to operate, convenient control, without the need to labor management, avoid the violation operation that human negligence causes.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of underground coal mine induction type of the utility model self-purging water curtain control device.
In figure: 1 is static pressure water pipe, 2 is 127V power line, and 3 is cables of heading machine, and 4 is bypass duct, and 5 is atomization water curtain, and 6 is electromagnetic valve, and 7 is start-stop sensor, and 8 is explosion-proof electric control box, and 9 is stop valve, and 10 is strainer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment that the utility model is done is described further.
As shown in Figure 1, a kind of underground coal mine induction type self-purging water curtain control device, comprise: the static pressure water pipe 1 being arranged on down-hole, 127V power line 2 and cables of heading machine 3, described static pressure water pipe 1 is communicated with bypass duct 4, the outlet of described bypass duct 4 is connected with atomization water curtain 5, described bypass duct 4 is provided with electromagnetic valve 6, described cables of heading machine 3 is provided with start-stop sensor 7, described electromagnetic valve 6 is connected with explosion-proof electric control box 8 respectively with start-stop sensor 7, the power input of described explosion-proof electric control box 8 is connected with the junction box on 127V power line 2.
In addition, described bypass duct 4 is also provided with stop valve 9 and strainer 10, described stop valve 9 and strainer 10 are all positioned at the front end of electromagnetic valve 6.
During concrete use, development machine starts, cables of heading machine 3 generation current, start-stop sensor 7 detects the electric current in cables of heading machine 3, and transmission of signal is to explosion-proof electric control box 8, explosion-proof electric control box 8 Controlling solenoid valve 6 is opened, and the water in static pressure water pipe 1 is along bypass duct 4 to atomization water curtain 5, realize spraying, wherein stop valve 9 normally duty be normally open.Whole process is simple, convenient, automatically controls, without the need to labor management, avoids the violation operation that human negligence causes.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; but the utility model is not limited to above-described embodiment; in the ken that those of ordinary skill in the art possess; the various changes can also made under the prerequisite not departing from the utility model aim, also should be considered as protection domain of the present utility model.
