Accumulated snow parameter measurement instrument and using method

Abstract

The invention aims to solve the technical problem of how to simply and efficiently measure accumulated snow parameters. An accumulated snow parameter measurement instrument comprises a host and a measurement scale, wherein the measurement scale comprises a main control shaft, measurement rods, a dielectric constant sensor and a temperature sensor; scales are arranged on the outer side of the measurement scale; the measurement scale is hollow; the main control shaft is vertically inserted into the measurement scale from top to bottom; the main control shaft is cylindrical; a vertical gear is arranged on the outer side of the main control shaft; a pair of measurement rods are arranged on the measurement scale at regular intervals; each pair of the measurement rods are located at the same horizontal height and are horizontally embedded into reserved holes in the measurement scale; the main control shaft is clamped between the measurement rods; the vertical gear matched with a main controlshaft gear is arranged on a contact surface between the measurement rods and the main control shaft; the dielectric constant sensor and the temperature sensor are respectively located at outer ends of the pair of measurement rods; lead wires are used for connecting the sensors with the host. According to the accumulated snow parameter measurement instrument, the accumulated snow parameters can bemeasured by vertically inserting the measurement scale into the bottom of the accumulated snow without the need of digging pits and vertically sectioning; the accumulated snow parameter measurement instrument is simple to operate.

Description

technical field [0001] The invention relates to the field of scientific research on snow cover, in particular to the measurement of snow cover parameters. Background technique [0002] Snow parameters are important parameters in snow hydrological models and snow quantitative remote sensing. Therefore, the measurement of snow parameters is very important in snow scientific research. At present, the snow parameter measurement device is mainly the Snow Fork snow characteristic analyzer. [0003] Snow Fork can measure electrical parameters such as resonance frequency, attenuation and 3-dB bandwidth, and use these measurements to accurately calculate the dielectric constant, and then calculate the snow layer density and liquid water content through semi-empirical equations. There are two main problems: 1. It needs to dig pits and vertical sections when using it, especially when the snow depth is large, the measurement process is time-consuming and labor-intensive, and a simple s...

Problems solved by technology

There are two main problems: 1. It needs to dig pits and vertical sections when using it, especially when the snow depth is large, the measurement process is time-consuming and labor-intensive, and a simple snow parameter measurement device is urgently needed; 2. A snow depth inserted into the measuring rod can only measure the data of one point, and the measurement efficiency is low
