Abstract

The invention relates to a double-bucket and double-siphon weighing rain gauge used for observing amount of precipitation. The rain gauge comprises a small water-holding bucket 1, a weightometer 2, an ejector sleeve crutch 3, a supporting spring 4, a siphon 5, a big water-holding bucket 6, the weightometer 7, the siphon 8, a spring fixed end 12, a spring 13, a stop tube holder 14 and a siphon guide slot 15. The rain gauge is characterized in that the ejector sleeve crutch 3 can float up and down along with the increase and decrease of rainwater in the small water-holding bucket 1 so as to trigger the siphon process of the big water-holding bucket 6. The rain gauge is provided with a hysteresis distance so as to ensure that the siphon of the big water-holding bucket and the small water-holding bucket does not occur at the same time. Before the siphon of the small water-holding bucket 1, the amount of precipitation is determined by the metering increment of the weightometer 2 in a unit time. In the siphon process of the small water-holding bucket 1, the amount of precipitation is determined by the increment of the metering summation of the weightometer 1 and the weightometer 2 in the unit time. The rain gauge has simple structure, low cost, high reliability, high measuring precision and absolute timeliness, and can be widely applied to precipitation observation in the hydrological and meteorological fields.

Description

technical field [0001] The invention relates to a rain gauge for detecting precipitation, in particular to a novel weighing rain gauge capable of continuous, uninterrupted and high-precision detection with the structural features of double barrels and double siphons. Background technique [0002] Precipitation observation is an important part of meteorological and hydrological observations, and it is also the focus of scientific research in many fields. The spatiotemporal distribution data of large-scale precipitation is an important content of the global precipitation database and an important information for verifying the global circulation model, while the regional precipitation data is the basic information for analyzing and diagnosing the variation of the climate system in the region. Real-time rainfall data is the main source of atmospheric science research and disaster prevention information during typhoons. The spatial density of the rainfall observation network form...
