Compared with the prior art, the utility model discloses utilize the sensor to detect, when main transport tunnel belt feeder and belt conflagration, smog or the flammable toxic gas condition such as exceed standard in the pit along the line take place, the water spray forms the cascade separation intensity of a fire through the spraying water installation of putting out a fire and spreads, prevents that the condition of a fire from expanding rapidly, wins the time for the further organization of colliery fire extinguishing relief, falls to the minimum with the loss.
Description
Technical Field
The utility model relates to a prevention and cure mine conflagration technical field specifically indicates a colliery main shaft belt catastrophe automatic alarm fire extinguishing system.
Background
Coal is the key point of the national energy development strategy, the underground coal resources in China are rich, and the construction of a high-efficiency underground emergency disaster relief system is an important technical approach for realizing safe and high-efficiency exploitation of the underground coal resources; coal mine fire is one of main disasters of mines, and the life safety of underground personnel is seriously threatened by poisonous and harmful gas, gas and dust explosion generated by coal mining.
When a fire disaster occurs, if the fire behavior can be controlled in the shortest time, the influence range of the fire disaster is reduced to the lowest, the effect of achieving twice the result with half the effort is certainly achieved, the main well belt is the key point of fire prevention and extinguishing of the whole mine, the fire behavior of the main well belt is controlled, the spread of the fire disaster can be reduced, and the loss caused by the fire disaster is reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, and provide a colliery main shaft belt catastrophe automatic alarm fire extinguishing system.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the automatic alarm and fire extinguishing system for the coal mine main well belt disaster is arranged on the coal mine main well belt and comprises a plurality of substations and a main station, wherein the substations and the main station are transmitted through communication lines; a water pressure control box and a water valve are arranged on one side of the substation, the water pressure control box is connected with the water valve through a water pipe, and the outlet side of the water valve is connected with a fire extinguishing spraying and sprinkling device; the substation is connected with a temperature sensor, a smoke sensor and an infrared probe through transmission lines, and the temperature sensor, the smoke sensor and the infrared probe are located above a coal mine main well belt.
Further, the space between the substations is 30 m.
Further, the substation and the master station are powered through a 127V alternating current power line.
