Background technology
Rainfall gauge (rainfall recorder or rain glass, rain gage) is that a kind of meteorologist and hydrologist are used for
Measure the instrument of the precipitation in somewhere in a period of time (measurement of snowfall then needs to use snow weighing gauge).It common are siphon
Three kinds of formula, tipping bucket type and Weighing type.
The remote gauged rainfall instrument that tipping-bucket rain-gauge is made of inductor and signal recorder, inductor by Sheng rain device,
Upper tipping bucket, counts the compositions such as tipping bucket, dry reed switch at metering tipping bucket；Logger is by counter, record pen, recording clock, control circuit board
Deng composition.Its working principle is that：Rainwater enters Sheng rain device by the mouth of a river of holding of the top, falls into water receiving funnel, is flowed into through bell mouth
Tipping bucket, when water accumulating volume reach a certain height (such as 0.1 millimeter), tipping bucket disequilibrium overturns.And tipping bucket is toppled over each time, all
Make switch connection circuit, conveys a pulse signal to logger, logger control recording pen gets off rainfall record, so past
Rainfall measurement can be got off again.
The rate that the tipping bucket that is filled with water of tipping-bucket rain-gauge stirs when rainfall is excessive can be accelerated, and may lead to tipping bucket in this way
In water all import tipping bucket in the water receivers of tipping bucket lower ends not yet and be put into next water receiving work, cause the metering of rainfall
There is error；And tipping-bucket rain-gauge structure is relatively complicated, and water velocity is slow, and there are the asking not to the utmost of water row in tipping bucket
Topic；And the tipping bucket of tipping-bucket rain-gauge is constant volume design, so the measurement accuracy of tipping-bucket rain-gauge is fixed from according to drop
Rainfall variation is adjusted.
