Tilting pluviometer for hydrogeology experiments

Abstract

The invention relates to a tilting pluviometer for hydrogeology experiments. The tilting pluviometer for hydrogeology experiments includes a number one precipitation gauge, a number two precipitationgauge and a fixed pedestal, wherein the fixed pedestal is arranged at the bottom end of the apparatus body; an upper end fixed base is arranged at and supported by the upper end of the fixed pedestal;two sampling cup holding tubes are symmetrically arranged at the upper side of the upper end fixed base; the number one precipitation gauge is arranged at the middle position of the upper side of theupper end fixed base; a number one precipitation gauge outer tube is arranged at the outer side of the number one precipitation gauge; the number two precipitation gauge is fixedly arranged at the upper side of the upper end fixed base at one side of the number one precipitation gauge; and number two drainpipes are correspondingly arranged at two sides of a number two precipitation gauge outer tube. The size of the number two precipitation gauge provided by the tilting pluviometer for hydrogeology experiments is the half of the size of the number one precipitation gauge; and the number two precipitation gauge and the number one precipitation gauge are completely the same in the internal structural design, and for the structural design, two precipitation gauge tools with different size canbe used to measure in the same region, and then an average value is taken, thus being convenient for improving the measuring accuracy.

Description

technical field [0001] The invention relates to the technical field of hydrological rainfall measurement equipment, in particular to a tipping bucket type rain gauge for hydrogeological experiments. Background technique [0002] A rain gauge, or rain gauge, rain gauge) is an instrument used by meteorologists and hydrologists to measure the amount of precipitation in an area over a period of time (measuring snowfall requires a snow gauge). The common ones are siphon type and tipping bucket type. On December 18, 1994, China's first optical rain gauge came out. [0003] Among them, the tipping bucket rain gauge is a telemetry rainfall instrument composed of a sensor and a signal recorder. Clock, control circuit board and other components. Its working principle is: rainwater enters the water receiver from the water receiving port at the top, falls into the water receiving funnel, and flows into the tipping bucket through the funnel mouth. And every time the tipping bucket fa...
