Description
Technical field
It is more particularly to a kind of to be used to detect tipping bucket exactly the present invention relates to a kind of full-automatic tilting bucket rain titrator
Udometric measurement error, to adjust tipping bucket size, accurately measures the full-automatic tilting bucket rain titrator of rainfall, category
In the hydrology, meteorologic survey fixture technology field.
Background technology
Atmospheric precipitation measurement is the important step of earth water circulation monitoring, is the important component that water resource is utilized,
It is many important factor in order such as climate change, geological disaster, flood damage early warning and environmental assessment, scholar seeks in the industry
A variety of methods carry out accurate measurement to rainfall.
Tipping-bucket rain-gauge measuring principle：The metering unit of tipping-bucket rain-gauge is mainly symmetrical tipping bucket, when turning over
When the water contained that struggles against reaches certain quantitative value, during suitable 0.1 millimeter of precipitation, tipping bucket is overturned, equipped with one piece small in the middle part of tipping bucket
There is tongue tube magnet steel, magnet steel upper end.When tipping bucket is stirred, magnet steel is scanned to tongue tube, and making dry-reed contact, moment closes because of magnetization
Unification time, sends out a circuit turn-on pulse, represents 0.1mm rainfall.Therefore, whether the capacity of tipping bucket is accurate, direct shadow
Ring the measuring accuracy of tilting bucket rain.
However, nature precipitation intensity is change, tipping bucket gage work is dynamic process.When raininess is very big, enter
The current of tipping bucket are as noted, and without stop, when reaching weight (volume) of design code, tipping bucket begins turning (t1), but at this moment
Rainwater still ceaselessly injects tipping bucket, until rainwater flows into another tipping bucket (t2), is measured in this period of t1~t2 △ t tipping bucket more
Water △ W be tipping bucket metering dynamic error △ E1, its mounted angle with tipping bucketThe factors such as raininess I are relevant.According to quality inspection
The data that department provides show, 0.2mm tilting bucket rain when raininess is 4mm/min, whenSurvey △ t=0.16
Second, △ W=0.32 gram, dynamic measuring error delta E1 reaches -5%.
The error of tilting bucket rain is mainly derived from the rainfall intensity of change, and natural precipitation intensity is mostly in 0.01~4mm/
Min changes, in order to improve measurement accuracy, and tipping bucket inclination angle can be adjusted when equipment is dispatched from the factory, and distributes error, makes small, big raininess two ends
Error is distributed symmetrically, and error is minimum when tipping bucket size is adjusted into raininess for 2mm/min, measurement result is less than 2mm/ in raininess
During min, error is positive deviation, when raininess is more than 2mm/min, and error is negative bias can be with from, total preciptation measuring result error
Partial offset.
Tipping-bucket rain-gauge application selection：Tilting bucket rain is used to monitor rainfall, there is different types of in the market
Tilting bucket rain, but tilting bucket rain is used widely with its cheap and reliable and stable characteristic.SL21-2006 rainfall is seen
Regulation does not need the precipitation station of rain day data in gauge model, and 0.2mm tilting bucket rains can be used, and Multi-year average precipitation is more than
0.5mm tilting bucket rains can be used in 800mm area.It is such as super although hydrology expert have studied numerous other types of rainfall gauge
Sound wave pluviometer, float-type rainfall gauge, weighing type rain gauge, siphon rainfall recorder, adding the result that mechanism part brings is
Cost is improved and reliability reduction.So, tipping-bucket rain-gauge is still to be widely used in automatic monitoring both at home and abroad at present
Rainfall gauge, tipping-bucket rain-gauge reliable operation is simple in construction, it is easy to which that rainfall is converted into electric signal output, is easy to remote
Transmission.
Tipping-bucket rain-gauge calibration method：To improve the measurement accuracy of tilting bucket rain, it is necessary to annual 2 calibratings tipping bucket rain
The accuracy of gauge.The precision of current assay tipping-bucket rain-gauge is all artificial calibrating, there is two kinds of methods：One is being applicable experiment
Room or the artificial recharge instrument drainage metering method of interior, this method are, with manually at the uniform velocity water filling, to measure tipping bucket actual displacement
It is used as measurement basis.For being already installed on the rainfall gauge that field is used, it is impossible at the uniform velocity water filling, rainfall gauge into rainfall gauge
Discharge outlet from the ground height only 20mm, can not also collect displacement.Second method is artificial water supply's checking method, and this method is
Water injection rate is first measured, certain raininess is simulated and slowly, equably injects tipping bucket, metering upset number of times from funnel.This method is
Displacement need not be measured, but key issue is that pouring speed must be controlled strictly quantitatively, at the uniform velocity.Especially it should be noted that to control raininess
It is sure not excessive, must not more falls suddenly suddenly, because error in dipping increases sharply with the increase of raininess.Therefore this method will be simulated
It is small, in, big three kinds of raininess be also extremely difficult.
Field tilting bucket rain calibration can only use second method：Artificial water supply's checking method, with special in hydrometeorology
10mm standard graduated cylinders measure 314g Fluid Dynamics 0.5mm/min, 2mm/min and 4mm/min raininess and equably injected from funnel
Tipping bucket, not only raininess is uncontrollable, and the remaining water in tipping bucket is even more to estimate, therefore, and calibration accuracy can not ensure.
