Abstract

The invention provides a coal mine safety monitoring device, and relates to the field of coal mine safety monitoring. The device comprises a support component, the support component comprises a bottomplate, a support pipe is fixedly connected onto the bottom plate, telescopic guide rail components are arranged on two sides of the top of the support pipe, and swing plate components are rotatably connected onto the telescopic guide rail components. The swing plate components are connected with a control line, the control line is provided with a control interface, and the control interface is provided with a monitoring sub-assembly and a support-free detection assembly. The monitoring sub-assembly or the support-free detection assembly is installed on the control interface, multi-point long-distance and high-low concentration monitoring of methane at different positions is achieved, meanwhile, the device is foldable in design, convenient to store and move and wide in equipment monitoringrange, and the monitoring efficiency is effectively improved.

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, large mine dust, large 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 and the space is small, so the traditional monitoring equipment is inconvenient to move and carry. Moreover, during the monitoring process, because methane is more hydrogen than air and affected by wind, the concentration of methane at different altitudes is different. Traditional monitoring equipment can only monitor methane concentration in horizontal positions, and th...
