The invention belongs to the technical field of gas, and relates to a coal mine underground gas monitoring and protecting device. The coal mine underground gas monitoring and protecting device comprises a shell, wherein a cover plate is arranged on the front surface of the shell, a rotating shaft is fixedly connected to the bottom end of the cover plate, and the cover plate is rotationally connected with the shell through the rotating shaft; and a fixing plate is fixedly connected to the top end of the cover plate, a fixing bolt is fixedly connected to the front surface of the fixing plate, a rotary knob is rotationally connected to the middle of the front surface of the shell, a torsional spring is fixedly connected to the front end of the outer surface of the rotary knob and fixedly connected with the shell, and connecting rods are rotationally connected to the top end and the bottom end of the front surface of the rotary knob. By arranging the cover plate, covering and popping can be conveniently achieved through the rotating shaft; and meanwhile, fixing is achieved through the rotary knob and the fixing rod, and the situation that when the shell is not used, a display screen on the shell is accidentally collided, scratches or damage is caused, and then normal use of the whole device is affected is avoided.
Description
technical field [0001] The invention belongs to the technical field of gas monitoring and relates to an underground gas monitoring and protection device in coal mines. Background technique [0002] The safety of coal mines cannot be ignored. Through the monitoring of mine gas, the real-time dynamic changes of gas can be grasped, so that relevant technical personnel can make appropriate technical treatment to prevent the gas concentration from exceeding the limit, so as to avoid gas accidents such as gas exceeding the limit and gas explosion. Accurate and effective monitoring of gas is one of the important measures to ensure safe production in coal mines and prevent gas explosion accidents, and it is also the basic basis for studying the law of gas gushing and evaluating the effect of gas control. [0003] At present, the display screen on the existing coal mine underground gas monitoring device is exposed during use and non-use, which is easy to cause scratches or unnecessar...
