Problems solved by technology
[0002] With the development of science and technology, coal mine underground workers need safety officers in the team to detect the underground gas concentration before they start work. The existing detection device is to fix the gas sensor on the outer wall of the helmet, which is convenient for safety officers to walk around and detect at any time. , but the long-term location of the gas sensor on the outer wall of the helmet not only increases the space occupied by the device, but also the gas sensor is easily damaged by collision, which affects its service life. Therefore, we propose an automatic gas alarm device for underground coal mines

The invention discloses an automatic alarm device for underground gas of a coal mine, and belongs to the technical field of underground alarms of coal mines. A control cabinet is mounted at the top ofa battery box. A clamping plate is hinged to the outer wall of the left side of the battery box. The top of the control cabinet is connected with the outer wall of the left side of a helmet through awire. An illumination lamp is mounted at the bottom of the outer wall of the right side of the helmet. A storage groove is formed in the outer wall of the right side of the helmet. A sealing plate ismounted at the right end of a horizontal plate. An alarm lamp and a micro gas sensor are mounted on the left side and the right side of the top of the horizontal plate. An adjustment bolt matched with an adjustment bolt hole is mounted on the outer wall of the front side of the helmet. According to the automatic alarm device for the underground gas of the coal mine, a compression spring is compressed or stretched to drive the horizontal plate to move left and right, and then the alarm lamp and the micro gas sensor can be stored in an inner storage cavity or out of the inner storage cavity, sothat the space occupied by the device is reduced, and meanwhile, the service life of the alarm lamp and the micro gas sensor are effectively prolonged.
Description
technical field [0001] The invention relates to the technical field of underground coal mine alarms, in particular to an automatic underground gas alarm device for coal mines. Background technique [0002] With the development of science and technology, coal mine underground workers need safety officers in the team to detect the underground gas concentration before they start work. The existing detection device is to fix the gas sensor on the outer wall of the helmet, which is convenient for safety officers to walk around and detect at any time. , but the long-term location of the gas sensor on the outer wall of the helmet not only increases the occupied space of the device, but also the gas sensor is easily damaged by collision, which affects its service life. Therefore, we propose an automatic gas alarm device for underground coal mines. Contents of the invention [0003] The object of the present invention is to provide a coal mine underground gas automatic alarm device...
