Abstract

The invention discloses an automatic explosion-proof device for an underground coal mine. The automatic explosion-proof device comprises a transmission mechanism, a trigger mechanism is fixedly mounted on the outer surface of one end of the transmission mechanism, a gas storage cylinder group is fixedly mounted on the outer surface of one end of the trigger mechanism, and a horn group is fixedly mounted on the outer surface of one side of the gas storage cylinder group. According to the automatic explosion-proof device for the underground coal mine, when explosion occurs due to dangerous gas or coal dust in an underground, the shock wave transmission mechanism receives an explosion shock wave signal, a transmission rod is rapidly pushed to do horizontal movement, the trigger mechanism in the explosion-proof device is started to pierce a blocking piece in the gas storage cylinder group, and high-pressure gas stored in the gas storage cylinder group is instantaneously sprayed out, so that a dry powder extinguishing agent stored in the horn group is quickly sprayed out under the action of the thrust of the high-pressure gas, and therefore a flame propagation path is covered in a large area, an explosion-proof dry powder barrier is formed, the effects of extinguishing flames and inhibiting explosion are achieved, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of coal mine explosion-proof technology, in particular to an automatic explosion-proof device for coal mines. Background technique [0002] The responsibility for safety production in coal mines is heavier than Mount Tai, and coal and gas explosions are one of the primary hazards faced in the production process of coal mines. Therefore, ensuring safe production in coal mines has always been clearly stipulated in relevant national standards. In mines with explosion hazards, in order to isolate or prevent explosion propagation, prevent secondary explosions from causing greater damage, effectively and reliably reduce explosion losses, and reduce casualties, it is usually necessary to install mechanical explosion-proof devices in underground tunnels. [0003] The existing coal mine automatic explosion-proof device is not purely mechanically started, the structure is complicated, the processing procedures are many, and the...
