Description
Technical Field
[0001] This utility model relates to the field of coal mine safety monitoring technology, specifically a coal mine tunnel safety monitoring device. Background Technology
[0002] Coal mines are unique working environments. During coal mining, gases such as methane, which are flammable and explosive, are released from the ore seams. Currently, air monitoring devices are installed in mine tunnels, with built-in methane concentration sensors to monitor the concentration of methane circulating in the air. To facilitate connection to cables at the bottom of the tunnel and for easy maintenance, these existing methane concentration monitoring devices are mostly fixed directly to the bottom of the mine tunnel. Through a probe of a fixed length extending outwards, they can only monitor the concentration of methane in the air circulating at the bottom of the tunnel.
[0003] Based on the above, the inventors have discovered the following problem: When using the current mine tunnel safety monitoring device, the methane concentration sensor does not have a height adjustment function, resulting in a relatively limited monitoring location and affecting the monitoring accuracy.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a safety monitoring device for coal mine tunnels, in order to achieve a more practical value. Utility Model Content
