Gas explosion-proof detector for underground operation and use method thereof

Abstract

The invention discloses a gas explosion-proof detector for underground operation, which comprises a bottom plate. The top of the bottom plate is fixedly provided with a top plate through supporting legs, the top of one side of the top plate is provided with an alarm, the top of the top plate is also provided with a trigger mechanism used for triggering the alarm to give an alarm, and the trigger mechanism comprises a mounting rotating shaft; the mounting rotating shaft is rotatably imounted on the front wall of the top plate, a cam is fixed to the outer wall of the mounting rotating shaft, a trigger piece is fixed to the outer wall of the protruding edge of the cam, a trigger switch is fixed to the position, close to the outer wall of the cam, of the front face of the top plate, and when the cam rotates, the trigger piece can make intermittent contact with the trigger switch. Through cooperation of the structures, the effect that the alarm degrees of detected gas with different concentrations are different is achieved, meanwhile, the effect that gas with different concentrations can be treated differently can be achieved, the anti-explosion effect is achieved, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a gas explosion-proof detector for underground operations. Background technique [0002] Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of coal accumulation by ancient plants. In a high-temperature, high-pressure environment, while coal is formed, gas continues to be generated due to physical and chemical effects. my country's coal mine gas accidents and fire accidents are the main disasters that directly threaten the safe production of mines, seriously affecting the safe production of coal mines. The healthy and stable development of my country's coal industry. [0003] Existing gas detection usually detects the concentration of gas by manually carrying a portable gas detector, or through a gas concentration sensor, but these detection methods can only play a role in detection. At this time, the gas cannot be ...

Problems solved by technology

[0003] Existing gas detection usually detects the concentration of gas by manually carrying a portable gas detector, or through a gas concentration sensor, but these detection methods can only play a role in detection. At this time, the gas cannot be processed immediately, which may lead to accidents, the limitation is poor, and it is impossible to remind people at what stage the gas concentration is at this time through the change alarm, and the real-time performance is poor.
