Anti-condensation nivometer with self-accumulated-snow-removal function

Abstract

The invention discloses an anti-condensation nivometer with the self-accumulated-snow-removal function. The nivometer comprises an outer barrel body, a clamping piece is arranged on the outer barrel body, a filtering layer and a polygonal roller are arranged in the clamping piece, and a spoon-shaped fan is arranged on the upper portion of the filtering layer; a funnel body is arranged below the filtering layer, and a water scraper is attached to the funnel body and connected with the lower portion of the filtering layer; a collecting container is arranged below the funnel body, a net-shaped tray is arranged below the filtering layer, a snow removal device is arranged on the net-shaped tray, a spring piece is arranged between the filtering layer and the net-shaped tray, the water scraper is provided with a grinding and scraping part, and a quick lime layer is arranged on the inner wall of the outer barrel body. Compared with the prior art, because tree leaves and other impurities are blocked by the filtering layer, the tree leaves and other impurities are prevented from blocking the nivometer; because the filtering layer rotates and shakes on the polygonal roller, it can be avoided that snow water is accumulated in impurities falling onto the filtering layer, snow can enter the nivometer faster through the snow removal device, and condensation blocking is avoided; the grinding and scraping part can rub the quick lime layer when rotating along with the water scraper, broken dust of quick lime flies out and makes contact with water, heat is generated, and internal icing is prevented.

Description

technical field [0001] The invention relates to a rain gauge or a snow water storage device for meteorological research, in particular to a self-cleaning and anti-condensation snow gauge. Background technique [0002] The snow measuring device is a special device used to collect snowfall. It is used to measure the snowfall amount per unit time in the area. The previous snow measuring device has a simple structure and a single function. There is no special treatment at the snow water collection port of the collecting device. There will be various problems, such as the evaporation and loss of snow water, the splashing or flying of snow water, and under wind and rain conditions, it will blow leaves, paper scraps and other debris to the collector bottle, resulting in blockage or interference with the collection capacity. , the above problems will more or less affect the accuracy of snow water collection and measurement. [0003] The invention with the patent number 2013102380...

Problems solved by technology

The significance of adding this technical feature is: in the experiment, it is found that increasing the height of the water storage device can indeed increase the water storage capacity of the water storage device when the rain intensity is large, but when the rain intensity is large, the water level of the water storage device rises, and the water pressure also decreases. The increase will lead to an increase in the flow rate of rainwater in the funnel outlet hole, which will increase the water output of the funnel hole and also cause measurement errors. The technical solution to this problem is to make a limit ring on the inner wall of the funnel mouth, and install a rubber ring on the limit ring , the aperture of the rubber ring is equivalent to the aperture of the water outlet of the funnel, so when the heavy rain is strong and the water level rises, the rising water pressure will also crush the rubber ring on the limit ring, and t
