[0002] Combustible gas monitoring devices are widely used in flammable and explosive places where combustible gas leakage may occur, such as oil depots, chemical plants, gas stations, gas stations, and liquefied gas stations. Through the built-in high-stability semiconductor gas sensor, it can effectively monitor the leakage of combustible gas and issue an alarm through the alarm.

The utility model includes a fixing seat and a fixing rod, and the fixing rod is fixedly connected to the rear wall of the fixing seat. The utility model selects four groups of gas sensors as the same gas sensors required according to the site requirements. When a combustible gas leak occurs in the site, the diffusion direction diffuses to the four groups with the leak point as the center. When the device is contacted, since the four groups of air intake pipes are set in different directions, the air intake on the side of the leak point is the first to enter the air. By consulting the monitoring log of the device, it is possible to quickly know the group of air intakes that first detects that the combustible gas exceeds the preset value, so that the direction of the leak point can be quickly locked, saving a lot of time for maintenance work. The four groups of gas sensors are respectively selected as oxygen sensors, coal gas sensors, liquefied petroleum gas sensors and natural gas sensors, which can monitor the concentrations of four gases at the same time, and have a wide monitoring range.
