A kind of rain, snow and sandstorm measuring device and measuring method

Abstract

The invention discloses a rain, snow and sandstorm measuring device, comprising a chassis (14) and a protective shell (2) for covering the chassis (14); the top of the protective shell (2) is provided with an adapter (1 ), the outlet of the adapter (1) is facing the inlet of the storage barrel (3), the bottom of the storage barrel (3) is provided with a filter (4) for passing rainwater, and the filter (4) A tipping bucket (5) is arranged at the water outlet, and a magnetic steel (7) is arranged on the tipping bucket (5), and a reed switch (6) is arranged on a bracket close to the magnetic steel (7), and the tipping bucket (5) ) is facing the water inlet of the water storage bucket (8), and the storage bucket (3) and the water storage bucket (8) are integrally connected and located on the load cell (10). The invention can distinguish liquid precipitation and solid precipitation, judge the weight gain caused by sandstorm, and the liquid precipitation in the water storage tank is not affected by evaporation, and the precipitation measurement accuracy can be improved.

Description

technical field [0001] The invention relates to an atmospheric precipitation measuring device and a measuring method, in particular to a measuring device and a measuring method capable of distinguishing between liquid precipitation, solid precipitation and sandstorms and improving the precision of precipitation measurement, belonging to the technical fields of hydrology and meteorological measurement. Background technique [0002] Atmospheric precipitation measurement is an important link in the monitoring of the earth's water cycle, an important part of water resource utilization, and an important influencing factor in many aspects such as climate change, geological disasters, flood disaster warning, and environmental assessment. Scholars in the industry have sought various methods to analyze precipitation Make precise measurements. [0003] At present, the weighing rain gauge currently used at home and abroad, the measuring principle of the weighing rain gauge is: the weig...

AI Technical Summary

Problems solved by technology

[0005] (1) Energy consumption for heating. In winter, the long-term heating of the rain and snow gauge keeps the temperature at 8°C, which consumes a lot of electricity;

[0006] (2) The surface of the barrel of the instrument is very large, which will cause evaporation and affect the measurement accuracy;

[0007] (3) It is impossible to distinguish between liquid precipitation, solid precipitation and sandstorms, resulting in erroneous measurement values;

[0008] (4) It is necessary to add antifreeze and evaporation suppression oil, which will cause errors and cause environmental pollution;

[0009] (5) Weighing rain gauges require manual drainage and, therefore, cannot be used in unattended telemetry stations
