Explosion-proof protection structure for dangerous gas environment of laser radar

Abstract

An explosion-proof protection structure for a dangerous gas environment of a laser radar comprises a first outer cover and a second outer cover, the first outer cover and the second outer cover are fixedly connected through bolts, an installation frame is welded to the outer surface of the first outer cover, and notches are formed in the positions, located on the two sides of the installation frame, of the outer surface of the first outer cover. The technical key point is that the outer surface of the laser radar is provided with a radar shell and is combined with a first outer cover for use,so that multi-layer protection of the laser radar is realized; the rubber inner sleeve in the radar shell is tightly attached to the outer surface of the laser radar and buffers impact force from theoutside, and the explosive-proof protection effect is achieved. The glass cover, the glass inner plate and the glass pressing plate are used in a combined mode and are all made of explosion-proof glass materials, so that the explosion-proof effect can be achieved while normal use of the laser radar is prevented from being affected. And meanwhile, the glass cover is spirally mounted, so that the position of the glass inner plate is fixed, and subsequent replacement operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of laser radar, in particular to a flameproof protection structure for a dangerous gas environment of laser radar. Background technique [0002] Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of targets. Its working principle is to send a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, the relevant information of the target can be obtained, such as Target distance, azimuth, height, speed, attitude, and even shape parameters, so as to detect, track and identify aircraft, missiles and other targets. [0003] Lidar is also used in a wide range of fields, and can perform various detection operations in hazardous gas environments; however, the use of lidar in such a dangerous environment requires the use of protectiv...

Problems solved by technology

[0003] Lidar is also used in a wide range of fields, and can perform various detection operations in hazardous gas environments; however, the use of lidar in such a dangerous environment requires the use of protective mechanisms, and the existing protective mechanisms of lidar can only achieve single Layer protection, it is easy to be damaged when it is impacted by the outside world; at the same time, the laser radar is an electrical component, which needs to be connected to the power supply, and if the joint group connected to the wire end in the mine is arced, it is easy to occur when it comes into contact with the flammable gas outside. explosion hazard
