A snow melting rate measuring instrument

Abstract

The invention discloses a snow melting rate measuring instrument, which comprises an upper snow accumulation measuring device and a lower snow melting water collection measuring device. The snow accumulation measuring device includes an inner ring nesting ring, an outer ring nesting ring and an integral nesting ring ring, the inner ring nesting ring and the outer ring nesting ring are set as concentric circles, the integral nesting ring is arranged below the inner ring nesting ring and the outer ring nesting ring, and the integral nesting ring is provided with an integral nesting inner ring and The overall nested outer ring, the overall nested inner ring corresponds to the nested ring of the inner ring, the overall nested outer ring corresponds to the nested ring of the outer ring, the bottom of the overall nested inner ring is provided with an inner ring bottom, and the overall nested The bottom of the outer ring is provided with an outer ring bottom; the snowmelt water collection measurement device includes an outer ring base and a water collection tank. A water collection pan and a weighing device are arranged in the water collection tank. The weighing device is located at the bottom center of the water collection tank. The bottom end of the water collecting vessel is set on the weighing device, the top of the water collection vessel corresponds to the integral nested inner ring, and the top of the outer ring base corresponds to the integral nested outer ring.

Description

technical field [0001] The invention relates to the technical field of snow melting research experimental devices, in particular to a snow melting rate measuring instrument. Background technique [0002] Snow melting is a complex process affected by the external energy obtained by snow. Topography, slope, slope aspect, surface vegetation type, altitude, and rainfall during snowmelt are also important factors affecting snowmelt. The snow melting rate measuring instrument is a measuring facility for indirectly quantitatively measuring the influence of external factors on the snow melting rate, and there are few related instruments in the world at present. Accurate measurement of snow thickness and weight is the key to determining snow accumulation and snow melting rate. The traditional method is to select a standard sample plot and calculate snow density and melting rate by measuring snow depth and snow weight, but this method is difficult to obtain The process data of snow m...

Accurate measurement of snow thickness and weight is the key to determining snow accumulation and snow melting rate. The traditional method is to select a standard sample plot and calculate snow density and melting rate by measuring snow depth and snow weight, but this method is difficult to obtain The process data of snow melting, and control experiments cannot be carried out. In addition, it is affected by external factors, such as the spatial distribution of snow depth in the sample plot, wind blowing snow, etc., resulting in large errors
