Automatic cleaning device and method for lens of outdoor optical facility

Abstract

The invention relates to an automatic cleaning device and method for a lens of an outdoor optical facility. The device comprises a protecting cover which is arranged on the top part of the optical facility, and an electric windscreen wiper arranged on the front end lens of the optical facility, wherein the cross section of the protecting cover is arc-shaped; bulges are axially arranged at intervals at two sides of the upper surface of the protecting cover; collecting grooves are respectively axially formed in the bottom parts of two sides of the protecting cover and used for collecting water flowing from gaps between the bulges; water storing grooves are formed in the bottom parts of the front ends of the collecting grooves; nozzles are arranged at the bottom parts of the water storing grooves and are respectively positioned at the upper side of the lens; a liquid level switch is arranged at an inlet of each nozzle and can be turned on to trigger the electric windscreen wiper to work. The device is simple in structure and practical, can automatically clean the lens of the outdoor optical facility, and prevents the lens from being polluted and failed to normally use.

Description

technical field [0001] The invention relates to an automatic lens cleaning device and method for outdoor optical facilities. Background technique [0002] With the development of society, the improvement of safety awareness and the need to protect public property, people's personal and property safety, all places are vigorously promoting safe cities, safe communities, safe border defense, safe forest areas, safe oceans, safe mining areas, etc., a large number of installations High-definition video surveillance is installed, and it is equipped with a fill light to clean the image at night, achieving a relatively ideal effect and effectively deterring criminals. [0003] However, most of the camera shields and fill light (projector) lamp shields currently on the market or in actual use do not have a wiper cleaning device, so that after wind and sun, the dust and dirt will affect the perspective effect of the lens at the front of the shield. , the rear end cannot get a clear i...

AI Technical Summary

Problems solved by technology

[0003] However, most of the camera shields and fill light (projector) lamp shields currently on the market or in actual use do not have a wiper cleaning device, so that after wind and sun, the dust and dirt will affect the perspective effect of the lens at the front of the shield. , the back end cannot get a clear image

[0004] Although the current camera protective cover has a wiper device, it is not designed to be used with water and can only be "dry scraped". In this way, the dry scraping will affect the imaging effect of the camera and become blurred.

[0005] In the uninhabited field or the camera is erected at a high place, even if there is a designed water storage tank, it is inconvenient to add water or manually scrub and maintain
