Laser ranging sensor protection cover and laser range finder

Abstract

The invention discloses a laser ranging sensor protection cover, and relates to the technical field of an optical electronic instrument. The protection cover comprises a cover body and a bottom support seat, wherein the cover body comprises a groove-shaped lower bottom, an arc-shaped upper cover covering the upper part of the lower bottom, a laser panel fixedly arranged at the front end part of the lower bottom, and a rear cover fixedly arranged at the rear end part of the lower bottom; the lower bottom comprises a base plate and side plates which are arranged at two sides of the base plate and are integrally formed with the base plate; a hole is formed in the laser panel and laser can run through the hole; and a drainage device is arranged on the base plate of the lower bottom. The laser ranging sensor protection cover has the following beneficial effects that by replacing a conventional integral glass panel with the laser panel with the hole, the laser can run through the hole without barriers, so that the actual range of a sensor is improved, the interference degree of sunlight is reduced, and the waterproof performance of the protection cover is taken into consideration as well.

Problems solved by technology

[0002] At present, with the development of optical technology and electronic technology, long-distance high-precision laser range finders have gradually been applied to slope monitoring systems, but with the in-depth application of this technology, more and more application problems have emerged , such as the problem that the waterproof performance of the equipment is difficult to reconcile with the light transmission of the waterproof structure. In the prior art, in order to ensure the waterproof performance of the laser rangefinder, a shell is installed outside the laser rangefinder sensor, and the shell at the front end of the laser rangefinder uses glass to isolate rainwater. , although the waterproof performance of the instrument is guaranteed, the actual range of the laser sensor is greatly reduced, and the range is reduced from 150 meters to about 60 meters. Considering the road width, slope angle, height and other issues, the monitoring distance is usually 100 meters The above results in unsatisfactory application of the laser range finder in the slope monitoring system; if a laser range finder with a larger range is selected, the cost of use will be greatly increased

At the same time, because the laser rangefinder is an optical instrument, it is seriously affected by sunlight. The existing laser rangefinder usually cannot obtain monitoring data during the day, resulting in a drop of more than half of the monitoring time, which is not conducive to field application; the existing laser rangefinder Due to the impact of sunlight and waterproof structures on the distance meter, after the monitoring effect is affected, special reflective markers must be set at the monitored points, resulting in some difficult-to-reach high slope areas that cannot be monitored using this technology
