The core component of tipping-bucket rain-gauge is the tipping bucket of two small rooms, is a tipping bucket machinery bistable mechanism.In the course of the work, rainfall flows into a small room of tipping bucket via rain container, and increase with the water yield, centre-of gravity shift, tipping bucket unstability, just overturns rapidly, is confided all by the rainwater of undertaking; Meanwhile, the tipping bucket of opposite side starts to accept rainwater, so circulates.Tipping bucket often overturns once, can send a pulse signal.Tipping bucket small room to accept rainwater long-pending to the water yield accepted and the pulse number sent during starting rapidly upset, be the rainfall amount that tipping-bucket rain-gauge records.
The moment that note small room starts to accept rainwater is t
1, tipping bucket unstability, the moment starting upset is rapidly t
2, tipping bucket turn to horizontal level, namely rain container stop to this small room water filling start simultaneously to the moment of another small room water filling be t
3, t
1to t
2the water yield that period rain container injects small room is W, t
2to t
3the water yield that period rain container flows out is Δ W.According to the principle of work of tipping-bucket rain-gauge, t
1to t
3once, recording rainfall is t in period tipping bucket upset
1to t
2the rainfall W of period injection small room, and the rainfall amount of reality is t
1to t
3the gross rainfall (W+ Δ W) that period flows out from rain container.Therefore, Δ W/ (W+ Δ W) is the course of action error of tipping-bucket rain-gauge.
Assuming that t
1to t
3period raininess is constant, then the water flow Q of rain container is constant, and W can be expressed as Q (t
2-t
1), Δ W can be expressed as Q (t
3-t
2).The size of W only depends on the design of small room itself, has nothing to do with raininess.Raininess increases, and Q increases, (t
2-t
1) reduce, Q (t
2-t
1) constant, namely sensibility reciprocal W is constant.Δ W is then relevant with raininess.(t
3-t
2) size only depends on the design of tipping bucket itself, have nothing to do with raininess, Q then increases with the increase of raininess, Q (t
3-t
2) then increase with the increase of raininess, namely Δ W increases with the increase of raininess.Therefore, the course of action error delta W/ (W+ Δ W) of tipping-bucket rain-gauge increases with the increase of raininess.
In the practical application of tipping-bucket rain-gauge, the volume of tipping bucket, sensibility reciprocal, resolution are all fixing, and raininess is change.Raininess within the specific limits time, tipping-bucket rain-gauge can normally work and variable meets accuracy requirement.When raininess is excessive, error increases, and causes the result of " heavy rain indeterminacy " to occur, records rainfall amount and be less than actual rainfall amount; When raininess is too small, tipping bucket may can not overturn, and causes the situation of " drizzle is non-inductive " to occur, records rainfall number of times and be less than actual rainfall number of times.
Summary of the invention
The utility model overcomes deficiency of the prior art, and provide one and utilize the tipping bucket of small one and large one two " parallel connection " forms to carry out surveying the double skip rain gage of rain, this vibrational power flow ensures the measuring accuracy to rainfall amount under the raininess condition of different size.
