Embodiment Construction

[0015] Such as Figure 1-Figure 2 As shown, an intelligent fire extinguishing device for an underground roadway of the present invention includes a monitoring system 1, an alarm system 2, a fire extinguishing system 3 and a control system 4, the monitoring system 1 is installed in the middle of the roadway roof 5, and the fire extinguishing system 3 and the alarm system 2 are installed in the On the upper part of the two sides 6 of the roadway, the control system 4 is respectively connected to the monitoring system 1, the fire extinguishing system 3 and the alarm system 2 through control cables. The monitoring system 1 is used to monitor the temperature change of the coal wall of the underground roadway in real time and judge whether there is spontaneous combustion happened.

[0016] The monitoring system 1 adopts the combination of temperature measurement method and gas analysis method. The environment of the underground roadway is complex, and the purity of the collected ga...

Abstract

An intelligent fire extinguishing device for an underground roadway, including a monitoring system, an alarm system, a fire extinguishing system and a control system. The system and the alarm system are connected separately, and the monitoring system is used to monitor the temperature change of the coal wall of the underground roadway in real time and judge whether there is spontaneous combustion. The present invention adopts the combination of temperature measuring method and gas analysis method to comprehensively judge whether spontaneous combustion occurs to improve the accuracy, and the azimuth memory function can also accurately judge the area where it occurs, and integrates monitoring and fire extinguishing to realize accurate fire extinguishing in a short time, which is more reflected The intelligence of the device. The invention integrates the monitoring and prevention of coal spontaneous combustion, realizes accurate, rapid and intelligent fire extinguishing from multiple aspects, thereby reducing economic losses and ensuring the safety of underground workers.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to an intelligent fire extinguishing device for an underground roadway. Background technique [0002] Fire is one of the five major disasters in coal mines, which accounts for a considerable proportion of coal disasters in our country. Coal spontaneous combustion is common in most coal mines in my country. It is difficult to detect coal spontaneous combustion in traditional coal mines. It not only loses a lot of high-quality coal resources every year, but also poses a certain threat to the safety of underground production. The mines with spontaneous coal combustion in my country account for 56% of the total number of mines; the fires caused by coal spontaneous combustion account for 90% of the total number of mine fires. At present, there is no fire extinguishing device in the underground tunnel of the coal mine, and it is difficult to put out the fire after a ...
