Description

Underground water curtain device

Technical Field

The application relates to the technical field of underground fire control, in particular to an underground water curtain device.

Background

The mine is usually provided with a whole underground coal mine production system, and the underground coal mine production system belongs to an unopened area, so that dense smoke formed once the fire is generated can not be timely dissipated, the largest mine disaster after the national construction is carried out in 1960, a plurality of workers are always left in the mine due to sucking underground toxic gas in the mountain western coal mine explosion, if toxic and harmful floating substances of smoke can be reduced, a guarantee is provided for the life safety of underground workers, and the modern mine system is provided with a mature ventilation system, but the arrangement is complex due to the fact that the whole area is required to be considered, and the complex system is easy to stop in case of accident, so that the life of workers is threatened.

Disclosure of Invention

In order to solve the above-mentioned problem, the present application provides a downhole water curtain device.

The application provides an underground water curtain device adopts following technical scheme:

the utility model provides an underground water curtain device, includes well, main pipe, a plurality of shunt tubes, fire alarm device and electric gate valve in the pit, the main pipe is hugged closely the well and is laid, and a plurality of shunt tubes are installed respectively on the main pipe, the shunt tube other end transversely sets up at the well top, every all install a plurality of shower nozzles on the shunt tube, electric gate valve installs at the main pipe front end, fire alarm device in the pit is connected with electric gate valve electricity.

The utility model further defines the technical scheme that:

preferably, the water diversion pipe is a DN25 water pipe, and the height of the water diversion pipe from the ground is 3m.

Preferably, a pressure reducing valve is arranged on the water main, and a pressure gauge is arranged behind the pressure reducing valve.

Preferably, the outlet pressure value of the pressure reducing valve is in the range of 0.5-1.0MPa.

Preferably, the spray heads are respectively arranged at two sides of the water diversion pipe and are uniformly distributed along the water diversion pipe.

In summary, the present application includes the following beneficial technical effects: the utility model is arranged outside two channels of an oil depot (a place where fire disaster is easier to happen underground), when fire disaster happens in a well, the underground fire disaster alarming device starts the electric gate valve, so that the spray heads at the upper part of the well start spraying water, the effect of reducing toxic and harmful floating substances in smoke is achieved, and because the underground fire disaster alarming device spreads over the whole well, no matter where fire disaster happens underground, the spray heads can spray water in time, the water quantity sprayed by the spray heads is far insufficient for extinguishing fire, the effect of reducing toxic and harmful floating substances in smoke is mainly achieved, and the survival rate of underground workers in the face of fire disaster is improved.

Description of the embodiments

The present application is described in further detail below in conjunction with figures 1-3.

The embodiment of the application discloses an underground water curtain device, refer to fig. 1-3, including well 1, main water pipe 2, a plurality of shunt tubes 3, fire alarm device 4 and electric gate valve 5 in the pit, main water pipe 2 is hugged closely well 1 and is laid, a plurality of shunt tubes 3 are installed respectively on main water pipe 2, the other end of shunt tube 3 transversely sets up at the top of well 1, shunt tube 3 is DN25 water pipe, shunt tube 3 is 3m from ground height, shunt tube 3 adopts DN25, i.e. the internal diameter is the water pipe of 25mm, on the one hand because its suitability has guaranteed if the water pipe goes wrong, can change in the first time, on the other hand because shunt tube 3 needs to supply a plurality of shower nozzles 6, so need the internal diameter thick, just can guarantee that every shower nozzle 6 can both have water to spout;

each water diversion pipe 3 is provided with a plurality of spray heads 6, the spray heads 6 are respectively arranged on two sides of the water diversion pipe 3 and are uniformly distributed along the water diversion pipe 3, the spray heads 6 are arranged on two sides, harmful substances in the air can be more comprehensively settled, the water diversion pipe 3 is 3m away from the ground, and most underground workers cannot be influenced by the water diversion pipe 3 or the spray heads 6;

the electric gate valve 5 is arranged at the front end of the main water pipe 2, the main water pipe 2 is provided with a pressure reducing valve 7, the rear of the pressure reducing valve 7 is provided with a pressure gauge 8, the outlet pressure value range of the pressure reducing valve 7 is 0.5-1.0MPa, under normal conditions, the water supply pressure needs to be controlled within 0.5-1.0MPa, if the pressure is too high, the spray head 6 is easy to wear, so that the water spraying quantity is not uniform;

the underground fire alarm device 4 is electrically connected with the electric gate valve 5, and the underground fire alarm device 4 mainly plays roles of monitoring fire and alarming, for example, an SPY fire source detector can serve as the task, and when the electric gate valve 5 is triggered by high-temperature flame, an electric signal is transmitted to the electric gate valve 5, so that the spray head 6 sprays water, the content of floaters in smoke generated by the fire is reduced, and the survival rate of underground workers in the case of the fire is improved.
