Description
Technical field
The utility model is related to the hydrology to verify utensil, particularly a kind of hydrological telemetering tipping bucket for being used to calibrate telemetering rain ga(u)ge
Rainfall gauge calibration instrument.
Background technology
Rainfall observation data is the important component of hydrological data, is to be related to climate change, geological disaster, flood calamity
Various important factor in order such as evil early warning, water resource utilization and environmental assessment, are widely used in hydrology automatic telemetry and rain
It measures in data collection solid-state memory system.Gradually substitution is traditional for tipping-bucket rain-gauge in China, rainfall observation instrument at present
Rain gauge and siphon rainfall recorder, be widely used in remote gauged rainfall.Tipping-bucket rain-gauge reliable operation, it is simple in structure, it can
Rainfall is converted into electric signal output, realizes remote transmission.Precipitation holds rain mouth by stack shell top, into tipping bucket, works as tipping bucket
When interior water reaches specified amount, tipping bucket can be because its own gravity be voluntarily overturn.Magnet steel is arranged at tipping bucket top, in rainfall gauge fixing bracket
On highly sensitive tongue tube is installed, in tipping bucket switching process, magnet steel leaves, generation is once turned over immediately close to tongue tube
Turn to generate a signal.Respectively there are one positioning screws for left and right below tipping bucket, adjust height, change tipping bucket angle of inclination, you can
Change the overturning amount of tipping bucket each time.Tipping bucket is overturn into runoff investigation into required value, such as 0.1 mm, 0.2 mm, 0.5 mm, 1.0
The corresponding weight of mm rainfall, then each signal represent the rainfall of 0.1 mm, 0.2 mm, 0.5 mm, 1.0 mm, realize that precipitation is distant

Accuracy.
2nd, tilting bucket rain itself is there are design defect, when the rainwater weight of upper small room metering reaches the setting sensibility reciprocal of instrument
When, by theoretically, upper small room should stop intaking immediately, and fall to do by the rainwater of metering rapidly, and at the same time, lower tipping bucket turns
It changes tipping bucket into, starts to accept rainwater, carry out the metering of the second bucket, be so repeated.And in fact, when tipping bucket is converted
Between be spaced, rainwater still continuous small room injection upwards, and the water within this time is just without passing through the metering of tipping bucket
It being included in practical precipitation, thus negative error has occurred, and with the increase of raininess, the water that this part is included in more is bigger,
Thus error is bigger.
3rd, the rating method of existing telemetering tilting bucket rain calibration instrument is when carrying out verification process, and water injects the upper of tipping bucket
Small room, when connect rainwater volume reaches predetermined value, upper small room is overturned by gravity, and from water receiving status transition to waiting shape
State；Lower small room then transits to water receiving state from wait state, and lower tipping bucket is converted into tipping bucket, and overturning every time exports preset value,
And so on, examine tipping bucket metering rainfall aggregate-value and be actually implanted into water difference whether coincidence loss range.Calibration process
Measure as cumulative precipitation, calibration process is very cumbersome, takes longer, and can not realize that monobucket is calibrated, may cause left small room with
Right small room difference in volume is excessive, increases rainfall gauge measurement error.
Accurate precipitation data can provide reliable basis for hydrologic forecast, calculating, analysis, be water resource utilization, disaster
Various important components such as early warning and environmental assessment, so the error problem of tipping-bucket rain-gauge will directly affect precipitation
The quality of data.Therefore in use, udometric measurement accuracy should be continuously improved, the application is aiming at problems above
And propose.
