Description

Self-cleaning visibility sight

Technical field

The utility model relates to the technical field of visibility observation instruments, in particular to a self-cleaning visibility observation instrument.

Background technique

In the context of the development of intelligent meteorology, real-time observation data of automatic meteorological observation systems have been closely linked to short-term forecasts and public services. Therefore, high-quality ground observation data is the basis for developing high-level meteorological operations. At present, existing automatic weather observation stations can achieve basic observation tasks by observing visibility. However, the visibility observers of most automatic weather observation stations use optical components to collect visibility. Impurities such as rain, snow, dust, etc. will affect the lens of the visibility observer. Causes pollution, resulting in inaccurate visibility data.

To address the above problems, one existing solution is to add a cleaning device to spray cleaning fluid into the lens to flush impurities on the surface of the lens. Since the cleaning fluid cannot dry quickly, it is easy to leave water stains on the surface of the lens, affecting the visibility of the observer. Accuracy, and when the weather gets cold, the water on the lens surface easily condenses into frost, which affects the use of the lens, so the cleaning method of spraying cleaning fluid is not suitable for winter.

Another existing solution is to install a protective cover in front of the lens to prevent impurities from entering the lens and reduce contamination on the surface of the lens. However, when working for a long time, it is inevitable that some impurities will enter the lens.

Another solution is to install a protective cover in front of the lens through a flip mechanism. When the visibility observer is working, open the protective cover to expose the lens. When the visibility observer stops working, close the protective cover to prevent impurities from contaminating the lens. Due to the high collection frequency of the visibility observer, data is usually collected every 15 to 60 seconds. Therefore, the flipping mechanism needs to frequently open and close the protective cover, and the parts are easily damaged. At the same time, if the protective cover is not opened in time, it will affect the collection of visibility data, resulting in Visibility data is inaccurate.
