Abstract

The invention relates to the technical field of coal mine safety monitoring, in particular to a coal mine safety monitoring apparatus, comprising a fixing housing, a fixed disc, a fixing support mechanism, a winding mechanism, a monitoring mechanism, an alarm mechanism , a rotating mechanism and a forcing mechanism. The fixing housing for mounting equipment is fixedly connected to the top end of afixing pillar; the fixing housing also for mounting monitoring equipment is arranged at the top of the fixed disc; the forcing mechanism for powering for the rotation of a rotary disc is arranged inthe fixing disc and connected to a first gear; the winding mechanism for winding and unwinding cables is arranged on the fixing housing; the monitoring mechanism for monitoring methane concentration and oxygen concentration in a mine is arranged on the fixing housing, the rotary disc and the fixed disc. The coal mine safety monitoring apparatus is capable of monitoring methane concentrations and oxygen concentrations in horizontal ranges of different heights and radiuses on a vertical line, and has better warning capacity.

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...
