Suspended track type movable fire-extinguishing explosion-proof device

Abstract

The invention relates to the field of mine fire, gas and derived disaster protection equipment, in particular to a suspended track type movable fire-extinguishing explosion-proof device. The device comprises a motion execution system, wherein the motion execution system is suspended on a track and can move along the track; a carrier, wherein the carrier is arranged in the motion execution system,a cavity is formed in the carrier, and an openable box door is arranged at the bottom side of the carrier; and a fire extinguishing system, wherein the fire extinguishing system comprises a fire extinguishing agent heat preservation layer arranged in the cavity. The suspended track type movable fire-extinguishing explosion-proof device of the invention can monitor the conditions of gas concentration, temperature and the like in a mine in real time; after detecting that a fire occurs in the mine, fire extinguishing treatment is carried out through the stored dry water-carbon dioxide hydrate fire extinguishing agent; and after the fire extinguishing treatment, if the gas concentration in a roadway is too high, a self-suction explosion-proof system is started to suck the gas into the storagecavity to form hydrate with the water solution, so that the concentration of the gas in the roadway is reduced, and gas explosion in the mine is avoided.

Description

Technical field [0001] The invention relates to the field of mine fire, gas and its derivative disaster protection equipment, in particular to a suspended rail type mobile fire extinguishing and explosion-proof device. Background technique [0002] Coal mine gas accidents and fire accidents in our country are the main disasters that directly threaten the safety of coal mines, severely affect the safety of coal mines, and restrict the healthy and stable development of our coal industry. [0003] In order to effectively curb the occurrence of gas disasters, real-time and continuous monitoring of gas concentration is particularly important to achieve the purpose of controlling gas concentration, reducing coal mine gas accidents, and ensuring coal mine safety production. The methods commonly used to detect gas concentration in underground mines mainly include: setting a gas concentration sensor at a designated location in the mine and a portable portable gas detector to detect the conc...

AI Technical Summary

Problems solved by technology

The methods commonly used to detect gas concentration underground mainly include: installing gas concentration sensors at designated locations in the mine and manually carrying portable gas detectors to detect the concentration. However, these methods for detecting gas concentration cannot achieve real-time and continuous detection, and have limitations. error

The fire extinguishing methods commonly used in the underground mainly include fixed-point grouting, high-level drilling water injection, spraying inhibitors, gel injection, drilling foam injection, and application of liquid carbon dioxide fire extinguishing devices. However, using these technologies to implement fire extinguishing is complicated. poor timeliness

[0004] It can be seen that the detection of gas concentration in existing mines cannot achieve real-time detection and continuous detection in a large area, and the fire accident cannot be detected in time and the disaster situation can be effectively controlled in an early stage.
