Description

[Technical field]

[0001] The utility model relates to the technical field of fire extinguishing in mining areas, in particular to a mine-used explosion-proof and intrinsically safe distributed temperature measuring and fire extinguishing host machine. [Background Technology]

[0002] During the coal mining process, flammable gases such as methane inherent in the coal seam are released as the coal and rock are broken and gather inside the mine to form an explosive mixture. In addition, fires may also be caused by static electricity, friction, lightning, etc. during the mining process. If the fire gets out of control, it will cause serious consequences, such as coal mine accidents, casualties, property losses, etc.

[0003] In order to avoid these hazards, coal mine fire extinguishing devices have the characteristics of rapid response, efficient cooling, comprehensive coverage, safety and reliability. Traditional coal fire extinguishing devices usually use smoke sensors to monitor the smoke generated during the combustion process, but in some cases, the flame cannot produce enough smoke for the sensor to monitor, resulting in missed fire detection or delay. In addition, the "smoke" signal monitored by the sensor is not necessarily caused by the fire. This false alarm may also cause trouble and inference errors to the staff, reducing the accuracy and reliability of monitoring. Therefore, it will be of great significance if a flameproof and intrinsically safe distributed temperature measurement fire extinguishing host specifically for mining areas can be provided. [Contents of the utility model]
