The invention relates to the technical field of
coal mine
flame-retardant devices, in particular to a
coal mine
flame-retardant explosion-proof device. The
coal mine
flame-retardant explosion-proof device comprises a high-pressure gun, a trigger device, a trigger rod and an spraying device, the high-pressure gun is arranged on one side of the trigger device, the spraying device is arranged on the other side of the trigger device, the explosive-proof device is installed at the top in a coal
mine tunnel through a hanging device, fire extinguishing
powder is arranged in the spraying device, the trigger rod is installed at the top in the coal
mine tunnel through the hanging device, a trigger plate is arranged at one end of the trigger rod, and the other end of the trigger rod is installed on the trigger device. According to the device, the high-pressure gun is arranged outside the spraying device, more fire extinguishing
powder can be stored in the spraying device, and compared with the prior art, no cavity is generated in the center when the fire extinguishing
powder is sprayed out, so that the fire extinguishing powder is uniformly distributed in a tunnel, the high-pressure gun does not occupy the space in the spraying device, sealing of the fire extinguishing powder is facilitated, powder leakage or damp is prevented, and regular replacement of the fire extinguishing powder is facilitated.
