Dustproof device and dustproof method for sensing probe

Abstract

The invention belongs to the field of dust proofing of gas sensing probes and discloses a dustproof device and a dustproof method for a sensing probe. The device comprises the sensing probe, a filter curtain, a shutter primary roller, a shutter secondary roller, a micromotor and a timing controller. Two ends of the filter curtain are connected with the shutter primary roller and a shutter secondary roller respectively, and an output of the timing controller is connected with the micromotor which is connected with the shutter primary roller. The method includes: mounting a dustproof device in the front of the sensing probe, controlling the shutter primary roller to rotate by the timing controller of the dustproof device to roll the filter curtain jammed by dust into the shutter primary roller, and updating the shutter from the cleaned filter curtain on the roller to the front of a gas inlet of the sensing probe to guarantee the environmental gas to enter the sensing probe without obstructions. The dustproof device and the dustproof method for the sensing probe have the advantages that the dustproof filter curtain of the probe can be replaced automatically, the dustproof problem of sensing probes for mine environmental gases such as gas, carbon dioxide and oxygen is solved, reliability in environmental safety monitoring is guaranteed, and the dustproof device and the dustproof method is suitable for dust on gas monitoring probes in other ground dust environments.

Description

technical field [0001] The invention relates to a dustproofing method and device for a gas sensing probe, in particular to a dustproofing method and device for a sensing probe. technical background [0002] At present, mine ambient gas sensing probes are installed underground in coal mines containing gas, carbon dioxide, and oxygen to detect the mine ambient gas. In the environment, the dust in the high-concentration dust environment will gradually block the air inlet of the monitoring probe, so that the monitoring probe cannot normally monitor the ambient gas in the coal mine, and the gas monitoring probe loses its monitoring function. At present, there is no other solution except to replace the gas monitoring probe regularly. Contents of the invention [0003] The object of the present invention is to provide a dust-proof method and device for a sensing probe to solve the problem that the dust in a high-concentration dust environment blocks the air inlet of the monitori...
