Description

Technical Field

[0001] The utility model relates to the technical field of gas detectors, in particular to a gas detector for coal mines. Background Art

[0002] Mining gas detectors, also known as mining gas meter, are suitable for measuring the concentrations of carbon monoxide (C0), oxygen (O2) and nitrogen dioxide (NO2) in underground mine working environments. The detector has an electrochemical gas sensor element inside, which displays the monitored gas concentration in real time on a color LCD screen; if the detected gas exceeds the set alarm value, it will warn of the danger through a light alarm.

[0003] The current gas detectors used in coal mines are usually handheld and carried to the coal mine detection area for detection. However, the handheld gas detector needs to occupy one hand of the person, which is inconvenient to pick up other items, and the handheld gas detector is easy to slip. Some gas detectors are currently provided with bolt mounting holes. When in use, the gas detector is installed in the detection area through the fixing bolts. When the gas detector is directly installed on the wall, it is more troublesome to operate when disassembling and repairing. In addition, the usage methods of these two gas detections are relatively simple. For this reason, we propose a gas detector for coal mines. Utility Model Content
