Coal mine rapid and automatic flame-retardant explosion-proof device and automatic detection control system thereof

Abstract

The invention relates to the technical field of coal mine flame-retardant devices, in particular to a coal mine rapid and automatic flame-retardant explosive-proof device and an automatic detection control system thereof. The coal mine rapid and automatic flame-retardant explosive-proof device comprises a high-pressure gas storage bin, an eruption powder storage bin, a trigger assembly and the automatic detection control system, the trigger assembly penetrates through the eruption powder storage bin, the high-pressure gas storage bin is arranged outside the eruption powder storage bin, a piston is arranged in the high-pressure gas storage bin, the trigger assembly comprises a transmission rod, the piston is connected with the transmission rod, and the high-pressure gas storage bin, the eruption powder storage bin and the trigger assembly are installed at the top in a coal mine tunnel through a hanging device. According to the coal mine rapid and automatic flame-retardant explosive-proof device, a shock wave receiving part directly transmits the impact force to the piston through the transmission rod, so that the fire extinguishing powder is ejected, the triggering mode is more direct, the triggering time is shorter, and the purposes of flame retardance and explosion suppression can be quickly achieved.

Description

technical field [0001] The invention relates to the technical field of flame retardant devices in coal mines, in particular to a rapid automatic flame retardant and explosion-proof device for coal mines and an automatic detection and control system thereof. Background technique [0002] In coal mines, explosions are generally divided into two categories, namely gas explosions and coal dust explosions. Regardless of whether it is a gas explosion or a coal dust explosion, its hazards are generally divided into four categories: first, high temperature. Mine fires, burnt equipment, burnt personnel; second, high pressure, the gas pressure after the gas explosion is 7 to 10 times the gas pressure before the explosion through experiments and theoretical calculations, and the theoretical pressure of the coal dust explosion can reach 735kPa, which can damage equipment, Push down the frame, causing roof fall and casualties; third, toxic and harmful gas, the concentration of carbon mo...

Problems solved by technology

[0005] However, there are some problems in the above-mentioned device: (1) The impact force of the shock wave needs to be transmitted layer by layer and finally reach the piston, so that the fire extinguishing powder is sprayed out. The eruption time is not conducive to flame-retardant and explosion-proof; (2) The high-pressure gas in the high-pressure tank needs to go backward to the sealing vent hole first, and then turn back to impact the fire extinguishing powder, so that the time from the triggering of the device to the spraying of the fire extinguishing powder is too long, which is not conducive to The fire extinguishing powder is quickly and evenly distributed in the roadway, which affects the fire extinguishing effect; (3) the high-pressure tank occupies a large amount of space in the storage bin, which reduces the reserve of fire extinguishing powder, and the flame-retardant and explosion-proof effect is not good; (4) the high-pressure tank is in storage. The warehouse takes up a lot of space. When the device is triggered to spray fire extinguishing powder, a cavity will be formed in the central part, and the distribution of fire extinguishing powder will be uneven, which will affect the effect of flame retardant and explosion proof; (5) The device can only deal with single Explosion in one direction cannot prevent explosion and combustion in another direction
