A wind-resistant capacitive snowfall measurement method

Abstract

The invention provides a wind-resistant capacitive snowfall measurement method, which includes a measuring device and a working process. The measuring device includes a rotating shaft, and the rotating shaft is connected to a measuring barrel through a suspension bearing. A capacitor is arranged next to the rotating shaft, and the capacitor is fixed On the rotating shaft and the measuring barrel, the measuring barrel is a square barrel structure with both ends transparent. The inner side of the measuring barrel is provided with two pairs of capacitor plates parallel to the left and right and parallel to the front and rear. The bottom of the measuring barrel is fixed by a fixing frame. The wind power tail rudder is equipped with rotor blades. The total amount of snow in the cylinder, the included angle of falling, wind speed and time are obtained through the measuring device, and then the total amount of snowfall is obtained through calculation and statistics. The invention adopts the design of a transparent measuring barrel, which is exquisite in design, can effectively solve the problem of excessive measurement error of the collection type in the windy area, and has high measurement accuracy and fast speed, and is very suitable for real-time monitoring and data accumulation of snowfall in large-scale water resource surveys .

Description

technical field [0001] The invention relates to a wind-resistant capacitive snowfall measurement method, which belongs to the technical field of land resource investigation and hydrological measurement. Background technique [0002] The investigation of water resources storage and changes is one of the major tasks of national security. Snowfall in mountainous areas is one of the key contents of the investigation of water resources storage and changes. The water sources of many rivers come from the melting alpine snow. However, due to the diversity of snowfall forms, the strong wind and air flow make the snowfall in the collection tank not regular, and even the negative pressure formed by the air flow field can cause the snow in the tank to fly out. The situation is relatively serious, which seriously affects the national resource strategy security and water use planning. Snowfall observation is also one of the contents of surface meteorological observation, which provides i...

AI Technical Summary

Problems solved by technology

At present, most of the hydrological surveys use the method of manual weighing of collection tanks to measure snow volume. However, improved rain and snow measurement equipment, laser, radar and other methods are affected by temperature, landform environment, wind field and other aspects. The impact is large, because there is a large error, it is not suitable for mountain measurement
