Description

technical field [0001] The invention relates to the technical field of explosion isolation, suppression, prevention and fire extinguishing equipment for coal mines, in particular to a data monitoring system for mechanical explosion-proof devices in coal mines. Background technique [0002] The responsibility for safe 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. [0003] In the prior art, in mines with gas or coal dust 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 machinery in underground tunnels. type explosion-proof device, but the mechanical explosion-proof ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in mines with gas or coal dust 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 machinery in underground tunnels. type explosion-proof device, but the mechanical explosion-proof device in the prior art mainly uses compressed high-pressure nitrogen as the driving source of the fire extinguishing agent. If the high-pressure gas cylinder in the device leaks and the pressure drops, the normal operation of the mechanical explosion-proof device cannot be guaranteed. At the same time, there is a lack of data monitoring of the on-site fire. Once an explosion occurs, if the mechanical explosion-proof device cannot effectively block the continuation of the explosion, it will bring a devastating blow to mine production and endanger the lives of miners. Difficulties in rescue work

[0004] However, the general supporting data monitoring system is basically laid through lines during use. Generally speaking, there is only one data monitoring substation for monitoring, which may easily lead to incomplete monitoring, making the relative harm of underground operations impossible to real-time Monitoring the pressure data of mechanical explosion-proof devices cannot increase the fire monitoring function and send out alarm signals in time. Therefore, we propose a data monitoring system for mechanical explosion-proof devices in coal mines
