Tipping bucket type rain gauge

Abstract

The invention discloses a tipping bucket type rain gauge. The gauge comprises a base, a gantry support fixedly arranged on the base and integrally formed, a support fixedly arranged at the top of thegantry support, a rain bearing funnel having the bottom penetrating through the support and fixedly installed on the support, a plurality of tipping buckets and metering buckets installed on the gantry support in a turnover mode, a rainfall induction mechanism fixedly installed on the gantry support, an output terminal connected and matched with the rainfall induction mechanism and one-point positioning mechanisms. The tipping buckets are installed on the gantry support in a turnover mode from top to bottom from the position below an outlet in the bottom of the rain bearing funnel through a plurality of pairs of tipping bucket supporting points, and longitudinal positioning grooves and the one-point positioning mechanism are further installed at the installation positions of the metering buckets of the gantry support. And the rainfall induction mechanism is located between the metering buckets and the tipping buckets above the metering tipping buckets, measures and counts rainfall andtransmits a result to the output terminal for final output of a rainfall numerical value. The gauge has the advantages of small rainfall metering error, high precision and simple structure.

Description

technical field [0001] The invention relates to the field of rainfall monitoring, in particular to a tipping bucket rain gauge. Background technique [0002] The structure of the existing tipping bucket rain gauge is generally composed of a bracket, a tipping bucket, a measuring tipping bucket and a counting tipping bucket. The assembly is relatively complicated. The structure of the bracket is also relatively complicated. When measuring heavy rainfall, because most of the existing rain gauges use a single tipping bucket design, a large amount of rainwater entering the tipping bucket for a short time may cause the tipping bucket to fail to be turned over correctly and in time, resulting in The rainwater in the bucket is lost, so the rain gauge cannot measure the rainwater currently entering the tipping bucket, which eventually leads to inaccurate rainfall measurement and poor precision. In terms of precision adjustment, most of the existing tipping bucket rain gauges use lef...
