Device for sampling parameters of environment outside underground shelter in coal mine and non-coal mine

Abstract

The invention relates to a device for sampling parameters of an environment outside an underground shelter in a coal mine and a non-coal mine, which is used for sampling parameters of the environment outside an underground mobile lifesaving cabin or a fixed refuge cave in the coal mine and the non-coal mine. The device comprises an air circulation pipe, a gas sampling structure, a multi-parametersensor structure and a sampled signal outputting device; the air circulation pipe is arranged outside the movable lifesaving cabin or the fixed refuge cave; and a sensor used for sampling is arrangedin the mobile lifesaving cabin or the fixed refuge cave and used for sampling air convected through the air circulation pipe in the mine. The sampling device disclosed by the invention solves the problem that the multi-parameter sensor for measuring the parameters of the environment outside the mobile lifesaving cabin or the fixed refuge cave cannot be used normally because the sensor is easy to be damaged by the impact force and the explosion force from the underground explosion and other disasters in the coal mine and the non-coal mine and can guarantee that the sensor is not destroyed in underground explosion and other disasters, but can still normally measure the environmental parameters.

Description

technical field [0001] The invention relates to the field of underground safety equipment for coal mines and non-coal mines, in particular to an environmental parameter sampling device for underground shelters of coal mines and non-coal mines. Background technique [0002] Coal mines and non-coal mines are high-risk industries with a high accident rate. At present, shelters are provided underground in coal mines and non-coal mines to provide a self-rescue shelter for those who cannot evacuate in time when an underground accident occurs. This underground refuge includes a mobile rescue cabin and a fixed refuge chamber. [0003] Since the shelters set up underground in coal mines and non-coal mines need to sample their external environmental parameters, the existing mobile rescue cabins or fixed refuge chambers sample the external environmental parameters directly through mobile rescue cabins or fixed shelters. It is realized by installing sensors outside the chamber. Howev...

AI Technical Summary

Problems solved by technology

However, the sensors directly installed outside the underground mobile rescue cabin or the fixed refuge chamber are easily damaged by the impact force and explosive force when disasters such as underground explosions occur, so that it cannot play its due role, and affects the mobile rescue cabin in the event of an explosion. Downhole application range

[0004] It can be seen that the above-mentioned existing mobile rescue cabin or fixed shelter outdoor environmental parameter sampling device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
