| description | An underground coal mine gas concentration monitoring and alarming security system comprises a box body, a controller, a gas concentration sensor, an audible and visual alarm and an automatic dust cleaning mechanism. The controller is located in the box body, and a control panel is vertically forward; the gas concentration sensor is located below the controller in the box body, the measuring face of the gas concentration sensor faces downwards horizontally, and the gas concentration sensor is electrically connected with the controller. The audible and visual alarm is fixedly mounted at the top end of the outer part of the box body and is electrically connected with the controller; and the automatic dust cleaning mechanism is arranged in the box body and is matched with a control panel of the controller and a measuring surface of the gas concentration sensor for use. By specially arranging the automatic dust sweeping mechanism, dust sweeping on the surfaces of the gas concentration sensor and the controller in |
