A portable high-sensitivity short-duration weak precipitation metering device

Abstract

The invention provides a portable high-sensitivity short-term weak precipitation metering device. The device includes a rainwater collector with a portable foldable configuration design, a rainwater collecting bottle and a water collecting outlet component. The folding structure is similar to an inversely umbrella-shaped structure, the water collecting outlet component is connected with the rainwater collecting bottle, and rainwater is led from the rainwater collector into the rainwater collector. The device is portable, can be used for high sensitivity measurement of short-term weak precipitation, can improve the sensitivity and accuracy of precipitation measurement, and is especially suitable for ground distributed type accurate monitoring of short-term weak precipitation in artificial precipitation operation in a Tianhe project.

Description

technical field [0001] The invention relates to a portable high-sensitivity short-time weak precipitation metering device, which is particularly suitable for ground distributed and accurate monitoring of short-time weak precipitation in the process of artificial rainfall enhancement in the Tianhe Project. Background technique [0002] In the atmospheric water vapor flux field, there are not only local strip structures with higher flux intensity than the surrounding areas, but also a water vapor transport network structure with relatively high flux in the entire water vapor flux field, forming global and regional water vapor Transport main channel. The concept of Tianhe is beneficial to our understanding of the water vapor transport in the atmosphere, and is of great value to the study of the statistical characteristics of the long-term evolution of the earth's water cycle and its interaction with the surface water cycle. At present, the concept of Tianhe has promoted the sc...

Problems solved by technology

[0004] However, in the prior art, it is generally a cylinder with a diameter of 20 cm, and the rain collection area is too small, and the sensitivity and accuracy of rainfall measurement within 1 hour are low, especially for light rain and moderate rain

In addition, in order to maintain the shape and area of ​​the barrel mouth, the barrel must be hard. If the diameter is large, the size and weight will be large, which is not easy to carry.

In addition, in the prior art rain gauge, in order to ensure the measurement accuracy, the diameter of the rain gauge is often made relatively small, which brings the defect that the water collection area is too small

Generally used to measure long-term precipitation and cannot be used to measure short-term weak precipitation

[0005] During the artificial rainfall enhancement operation of the Tianhe Project, light rain and moderate rain often occur, which belong to short-term weak precipitation, and it is difficult to rely on the existing standard rain gauge to accurately measure the distribution of surface rain intensity
