A Weighing Rain Gauge Structure Suitable for Freezing Rain Precipitation Measurement

Abstract

The present invention proposes a weighing type rain gauge structure suitable for freezing rain precipitation measurement, including a casing, an inner cylinder arranged in the casing, an inner cylinder support, a freezing rain collection plate, a precipitation collection bucket, and a load cell for the precipitation collection bucket and the total load cell, the shell and the inner cylinder are movably connected at the top to form a water receiving port, the precipitation collection bucket is arranged on the load cell of the precipitation collection bucket, and the outlet of the inner cylinder is located directly above the precipitation collection bucket, The weighing sensor of the precipitation collecting bucket is arranged on the said overall weighing sensor, and the said inner cylinder is also arranged on the said overall weighing sensor through said inner cylinder support; The inner cylinder is located directly below the water receiving port, and the diameter of the freezing rain collection plate is larger than that of the water receiving port. The invention can significantly improve the accuracy of freezing rain precipitation measurement, and provide reliable scientific data for scientific research on freezing rain disasters.

Description

technical field [0001] The invention relates to a rain gauge, in particular to a weighing rain gauge structure suitable for freezing rain precipitation measurement. Background technique [0002] Precipitation measurement is an important part of surface meteorological observation and an important part of atmospheric water cycle monitoring. Precipitation measurement is aimed at the liquid or solid (after melting) water that falls from the sky to the ground, and measures the accumulation depth of precipitation on the horizontal surface that has not evaporated, infiltrated, or lost within a certain period of time, that is, the amount of precipitation. Instruments used for precipitation measurement include the following main categories: rain gauges, tipping bucket rain gauges, siphon rain gauges, and weighing rain gauges. [0003] The rain gauge is composed of a rain gauge and a measuring cup, and the rain gauge includes a water receiver, a water storage bottle and a water stora...
