Abstract

The invention relates to a laser sensor probe and its filter screen cover, wherein the filter screen cover includes a screen cover body, a filter screen and a foam metal sheet; the screen cover body is a cylindrical body connected up and down, and its upper end is connected to the The probe is threadedly connected, the lower end is provided with a baffle, the filter screen and the foam metal sheet can be detachably set in the net cover body, and the filter screen is close to the upper surface of the baffle; there is also a filter screen and the foam metal sheet Gasket; the upper surface of the metal foam sheet and the inner side wall of the net cover body are fixed by a C-shaped snap spring. The structure is simple and easy to use. Under actual working conditions, it can protect the laser sensor probe to a certain extent, and avoid the situation that the normal operation of the probe is affected due to the accumulation of dust and water vapor on the laser optical path in harsh environments.

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. ,...
