Abstract

A coal mine safety monitoring device, which relates to the field of coal mine safety monitoring, comprises a support assembly, the support assembly includes a base plate, a support pipe is fixedly connected to the base plate, and two sides of the top of the support pipe are provided with telescopic guide rail assemblies, so the A swing plate assembly is rotatably connected to the telescopic guide rail assembly, a control wire is connected to the swing plate assembly, a control interface is provided on the control wire, and a monitoring subassembly and an unsupported detection assembly are installed at the control interface. The invention installs monitoring sub-assemblies or unsupported detection assemblies at the control interface to realize the concentration monitoring of methane at multiple points, long distances, and at different heights. At the same time, the device is foldable design, which is convenient for storage and movement, and has a wide range of equipment monitoring and improved monitoring efficiency. effectively improve.

Description

technical field [0001] The invention relates to the technical field of coal mine safety monitoring, in particular to a coal mine safety monitoring device. Background technique [0002] The underground coal mine is a special working environment, with flammable, explosive, combustible and corrosive gases, humidity, water spray, large mine dust, large power grid voltage fluctuations, serious electromagnetic interference, narrow space, and long monitoring distance. Therefore, the mine monitoring system is different from the general industrial monitoring system. [0003] However, the monitoring distance of the mine is long, the idle space is small, and the traditional monitoring equipment is inconvenient to carry. Moreover, during the monitoring process, due to the fact that methane is stronger than air hydrogen and is affected by wind, the concentration of methane at different heights is different. Traditional monitoring equipment can only monitor the methane concentration in ...
