Description
Technical field
The present invention relates to a kind of full-automatic tilting bucket rain titrator, particularly relate to a kind of measuring error for detecting tilting bucket rain exactly, to adjust tipping bucket size, the full-automatic tilting bucket rain titrator measured the amount of rainfall exactly, belongs to the hydrology, meteorologic survey fixture technology field.
Background technology
Atmospheric precipitation measurement is the important step of earth water circulation monitoring, it is the important component part that water resource utilizes, also be many-sided important factor in order such as climate change, geologic hazard, flood damage early warning and environmental assessment, scholar seeks multiple method and carries out accurate measurement to rainfall amount in the industry.
Tipping-bucket rain-gauge measuring principle: the metering unit mainly symmetrical tipping bucket of tipping-bucket rain-gauge, when the water yield that tipping bucket contains reaches certain quantitative value, during suitable 0.1 millimeter of precipitation, tipping bucket overturning, one block of little magnet steel is housed in the middle part of tipping bucket, and there is tongue tube magnet steel upper end.When tipping bucket stirs, magnet steel scans tongue tube, dry-reed contact is closed once instantaneously because of magnetization, sends a circuit turn-on pulse, represent the rainfall amount of 0.1mm.Therefore, whether the capacity of tipping bucket is accurate, directly affects the measuring accuracy of tilting bucket rain.
But nature precipitation intensity is change, and tipping bucket gage work is dynamic process.When raininess is very large, enter the current of tipping bucket as note, 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), in t1 ~ t2 this period △ t, the water yield △ W of the many meterings of tipping bucket is tipping bucket metering dynamic error △ E1, and it is relevant with the factor such as mounted angle φ, raininess of tipping bucket.According to the data display that quality testing department provides, the tilting bucket rain of 0.2mm is when raininess is 4mm/min, and when φ=12 °, survey △ t=0.16 second, △ W=0.32 gram, dynamic measurement error delta E1 reaches-5%.
The error of tilting bucket rain is mainly derived from the rainfall intensity of change, natural precipitation intensity changes at 0.01 ~ 4mm/min mostly, in order to improve measuring accuracy, tipping bucket inclination angle can be adjusted when equipment dispatches from the factory, distribute error, little, large raininess two ends error is distributed symmetrically, tipping bucket size being adjusted to raininess is that 2mm/min time error is minimum, make measurement result when raininess is less than 2mm/min, error is positive deviation, when raininess is greater than 2mm/min, error be negative bias from, total preciptation measuring result error can partial offset.
Tipping-bucket rain-gauge application choice: tilting bucket rain, for monitoring rainfall amount, has dissimilar tilting bucket rain in the market, but tilting bucket rain is used widely with its cheap and reliable and stable characteristic.Specify the precipitation station not needing data on rain day in SL21-2006 rainfall observation criteria, can use 0.2mm tilting bucket rain, the area that Multi-year average precipitation is greater than 800mm can use 0.5mm tilting bucket rain.Although hydrology expert have studied the rain gage of a lot of other types, as Ultrasonic Rain Gauge, float-type rain gage, weighing type rain gauge, siphon rainfall recorder, adding the result that mechanism part brings is that cost improves and reliability reduction.So tipping-bucket rain-gauge is still the rain gage being widely used in automatic monitoring at present both at home and abroad, tipping-bucket rain-gauge reliable operation, structure is simple, is easy to that rainfall amount is converted to electric signal and exports, be convenient to long-distance transmissions.
Tipping-bucket rain-gauge calibration method: for improving the measuring accuracy of tilting bucket rain, needs the accuracy of annual 2 calibrating tilting bucket rains.The precision of current assay tipping-bucket rain-gauge is all artificial calibrating, has two kinds of methods: the first is suitable for the man-made injection instrument drainage metering method of laboratory or indoor, and this method is with artificial at the uniform velocity water filling, measures tipping bucket actual displacement as measurement basis.For the rain gage being arranged on field and using, cannot at the uniform velocity water filling in rain gage, rain gage freeing port overhead highly only 20mm, also cannot collect water discharge.Second method is artificial water supply's checking method, and this method first measures water injection rate, simulates certain raininess and slowly, equably injects tipping bucket from funnel, metering upset number of times.This method to measure water discharge, but key issue is pouring speed must strict control quantitatively, at the uniform velocity.Especially it should be noted that will control raininess is sure not excessive, more must not fall suddenly, suddenly because error in dipping increases sharply with the increase of raininess.Therefore this method to simulate little, in, large three kinds of raininess are also very difficult.
Field tilting bucket rain calibration can only adopt second method: artificial water supply's checking method, the raininess measuring 314g Fluid Dynamics 0.5mm/min, 2mm/min and 4mm/min with 10mm standard graduated cylinder special in hydrometeorology injects tipping bucket from funnel equably, not only raininess is uncontrollable, the remaining water yield in tipping bucket cannot be estimated especially, therefore, calibration accuracy cannot ensure.
