AI Technical Summary
Current underground well gas monitoring relies on manual opening of the cover for inspection, which poses a safety risk of gas leakage and cannot monitor water levels in real time, resulting in insufficient detection accuracy and safety.
A gas monitoring device comprising a frame, a main housing, a combustible gas sensor, a water immersion electrode, and a servo motor was designed. The main housing is automatically raised and lowered by a lead screw driven by the servo motor. Combined with the real-time detection of the combustible gas sensor and the water immersion electrode, the controller analyzes the data and links the alarm and wireless communication module to achieve high-precision monitoring and remote early warning.
It enables high-precision monitoring and remote early warning of gas and water accumulation in well chambers, improving the safety and operation and maintenance efficiency of underground well chamber operations, and avoiding the safety risks and detection delays of manual inspections.
