During detection, the rotation of the servo motor 4 is controlled to drive the rotation of the turbine blades 5, thereby driving the gas flow. After the air at the detection position is filtered through the filter, it is extracted to the position of the gas detector 6, detected by the gas detector 6, and finally discharged from the breathable net 17. The gas detector 6 transmits the detected gas components to the corresponding monitoring instrument through the explosion-proof cable for display.
