A dust-proof structure for laser remote sensing detector

Technical Field

The utility model relates to the technical field of methane laser remote sensing detectors, in particular to a dustproof structure of a laser remote sensing detector.

Background Art

The methane laser remote sensing detector is used to detect methane leaks at long distances. It can be used for detection in places that people cannot enter. The methane laser remote sensing detector also needs to provide dust protection for the probe and data display screen to avoid affecting the detection results and hindering people from viewing the detection data. With the changes in technology, people's requirements for the dust-proof structure of methane laser remote sensing detectors are getting higher and higher.

In order to protect the front-end probe of existing methane laser remote sensing detectors, a dust cover is usually installed at the front end of the probe. The operator needs to remove it manually when using it. However, the removed dust cover is easy to be lost during use due to its small size as an independent individual. Therefore, we propose a dustproof structure for laser remote sensing detectors.
