Laser sensing probe and filter mesh enclosure thereof

Abstract

The invention relates to a laser sensing probe and a filter mesh enclosure thereof. The filter mesh enclosure comprises a mesh enclosure body, a filter net and a foam metal plate; the mesh enclosure body is a barrel running through from top to bottom, wherein the upper end of the mesh enclosure body is in threaded connection with the laser sensing probe, the lower end is provided with a baffle plate, the filter net and the foam metal plate are detachably arranged in the mesh enclosure body, and the filter net is closely fit to the upper surface of the baffle plate; a washer is also arranged between filter net and the foam metal plate; and the upper surface of the foam metal plate and the inner side wall of the mesh enclosure body are fixed by virtue of a C-shaped snap spring. The laser sensing probe is simple in structure and convenient to use; and under the real working condition, the laser sensing probe can be protected, so that dust and water vapor can be prevented from being aggregated on a laser optical path in a severe environment, which influences the normal work of the probe.

Description

technical field [0001] The invention belongs to the technical field of laser sensor accessories, and in particular relates to a laser sensor probe and a filter net cover thereof. Background technique [0002] Laser sensors can be used to detect the concentration of dangerous gases such as methane, etc., and are used in coal, petrochemical, electric power, metallurgy and other special fields where gas outburst or leakage may occur and pose a major threat to people's property and life safety. However, as the product is used for a long time, due to poor working conditions, dust will more or less accumulate on the laser optical path, affecting the optical path structure, resulting in a decrease in detection accuracy and sensitivity, and in severe cases, the laser probe will also be damaged. total failure. Contents of the invention [0003] The present invention aims to provide a laser sensing probe and its filter screen cover, which are simple in structure and easy to use. ,...
