Problems solved by technology

[0003] However, most of the current gas concentration monitoring and early warning devices are fixed, and the air inlet can only face one direction. However, the gas flow direction in the tunnel is not fixed. When the gas leaks but the gas flows to the air inlet that does not pass through the monitoring device, the The device will not be able to monitor and warn the gas leakage in a timely and accurate manner, which may easily cause safety accidents, and the gas concentration monitoring and early warning devices currently on the market, when performing safety monitoring and early warning work in the mine, because the mine environment is more complex, in When the device body moves, it is easy to collide with the surrounding mine walls, which will cause the device body to easily break down during the working process

Abstract

The invention discloses a gas concentration monitoring and warning device for coal mine gas extraction. The gas concentration monitoring and warning device comprises a gas concentration monitoring and warning device main body, wherein a connecting block is rotatably connected to one side of the gas concentration monitoring and warning device main body, a soft rubber block is fixedly connected to the lower surface of the gas concentration monitoring and warning device main body, a lifting mechanism is arranged on the back face of the gas concentration monitoring and warning device main body, a protection mechanism is arranged on one side of the gas concentration monitoring and warning device main body, and an air inlet mechanism is arranged on the top of the gas concentration monitoring and warning device main body. The gas concentration monitoring and warning device has the beneficial effects that the multi-directional air intake monitoring of gas concentration is facilitated, and faults cannot be caused to the device main body due to collision during movement.

Description

Technical field [0001] The present invention relates to a gas concentration monitoring early warning device, specifically a gas concentration monitoring early warning device for coal mine gas extract, belonging to the field of gas technology. Background technique [0002] In the coal mine, pay attention to safety is the most important, while the coal mine often runs through the gas area, so the monitoring of gas concentration in the coal mine is extremely important. The gas concentration monitoring and early warning device is specifically for monitoring Early Was Concentration. [0003] However, the current gas concentration monitoring and the early warning device are mostly fixed, and the air outlet can only be directed toward one direction, but the gas flow direction in the tunnel is not fixed, when gas leaks but the gas flows without the air opening of the monitoring device, The device cannot monitor and early warning in time and accurate, it is easy to cause safety accidents,...
