Description
Technical field
The utility model relates to a kind of rain gage, and particularly a kind of bitubular Weighing type rain gage is applicable to industries collection rainfall amounts such as the hydrology, meteorology, ocean, environmental protection, military affairs, agricultural, railway, aviation.Be particularly useful for requiring at heavy rainfall the industry of continuous coverage high precision, instant rainfall information.
Background technology
At present, most tipping bucket type, hydrocone type or the Weighing type rain gages of adopting of domestic collection rainfall amount.Wherein, the structure of tipping-bucket rain-gauge is made up of rain container, bucket tipping gear, sebific duct, water receiver and shell.During work, rainwater falls into the water receiving funnel by rain container, flows into tipping bucket through bell mouth, when water accumulating volume reach a certain height, and during as 0.1 millimeter, tipping bucket out of trim and toppling over.And tipping bucket is toppled over each time, all makes the switch connection circuit, carries a pulse signal to register, and recorder trace deposits in the internal storage location, the rainfall amount measurement can be got off and so forth.But when running into heavy rain and extra torrential rain, tipping-bucket rain-gauge can be slow because of the tipping bucket slewing rate of bucket tipping gear, even have little time to topple over, and causes rainfall data to be lost.And the record rainfall value precision only be 0.1mm, rainfall intensity measurement range 0～4mm/min.Also there is shortcomings such as need often safeguarding, change recording chart in tipping-bucket rain-gauge.Siphon rainfall recorder is made up of rain container, float chamber, recording clock, U trap etc., the groundwork principle is when the rainfall in the float chamber reaches a certain amount of, produces siphonic effect, automatically rainwater is discharged, cycle index like this, whole process all is recorded on the self-recording paper automatically.Its shortcoming is when draining, inevitably with that period of draining, is generally less than 14 seconds rainfall amount and also together discharges, and causes error.The precision of siphon rainfall recorder also only is 0.1mm, rainfall intensity measurement range 0～4mm/min.Need change self-recording paper every day in addition, more loaded down with trivial details.The Weighing type rain gage mainly is that the rainfall to monotubular carries out weighing, can't meet the demands when heavy or torrential rain.
Summary of the invention
For the rainfall data that overcomes rain gage existence commonly used is lost, precision is not high, the shortcoming that operation note is frequent, the utility model provides a kind of bitubular Weighing type rain gage, this rain gage can be during heavy or torrential rain continuous acquisition rainfall or at instantaneous collection rainfall, not only data are not lost, and precision reaches 0.01mm.
The utility model achieves the above object by the following technical programs: a kind of bitubular Weighing type rain gage is provided, adopt LOAD CELLS, use for reference the principle of electric bridge, by the rainwater weight in two precipitation gauges of weighing in turn, convert relevant rainfall value simultaneously to, reach the purpose of real time record rainfall.
A kind of bitubular Weighing type rain gage, this rain gage is by rain container, following mouth, water trap, the water trap pallet, water trap tray support post, first precipitation gauge, second precipitation gauge, first LOAD CELLS, second LOAD CELLS, the 3rd LOAD CELLS, the rain gage base, drainpipe, the precipitation gauge base, LOAD CELLS back-up block and rain gage urceolus are assembled, the water trap of an inverted V-shaped is installed in described Xia Zui bottom, described water trap the right and left is respectively equipped with first precipitation gauge and second precipitation gauge, described first precipitation gauge is installed on the 3rd LOAD CELLS, nozzle is over against the left side bypass channel of water trap, second precipitation gauge is installed on first LOAD CELLS, nozzle is over against the right bypass channel of water trap, first LOAD CELLS is installed on the LOAD CELLS back-up block, on connect second precipitation gauge bottom, second LOAD CELLS is installed on the LOAD CELLS back-up block, second LOAD CELLS is located between first LOAD CELLS and the 3rd LOAD CELLS, described the 3rd LOAD CELLS is installed on the LOAD CELLS back-up block, on connect first precipitation gauge bottom.
Described water trap is to become the inverted v-shaped bypass channel to be welded by two, is fixed on the guide rail of water trap pallet.
Described water trap adopts its move left and right of Single-chip Controlling step motor drive.
Described second LOAD CELLS is unloaded.
When raining, rainwater flows to water trap from rain container through following mouth, water trap is precisely controlled its move left and right by single-chip microcomputer, rainwater earlier from water trap while flowing into same precipitation gauge, when this precipitation gauge reaches certain rainfall, water trap moves to another side, and rainwater is injected another precipitation gauge, and so multiple weighing is returned in circulation.After water trap is shifted to another side, claimed the precipitation gauge of weight promptly to start the water pump draining.Software weighs up the weight of precipitation gauge according to LOAD CELLS, compare various parameters again, remove various disturbing factors, according to corresponding relation as second LOAD CELLS of criteria factor, convert the rainfall value to and deposit in the internal memory, in order to timed sending data or reading of data at any time.
Characteristics of the present utility model are:
1, adopts three and be high precision, high-resolution LOAD CELLS, can monitor rainfall intensity scope 0～15mm/min.
2, adopt high resolving power standard LOAD CELLS LOAD CELLS as a comparison, can realize calibration automatically, solve since temperature is floated or drift to the influence of weighing results, the that time that is simultaneously beginning to weigh, sensor can be removed the peel, comprise sand and dust, worm ant, foreign material etc., this also is a high assurance of whole weighing precision.
3, can gather the rainfall value of heavy or torrential rain uninterruptedly, in real time, accurately react instantaneous rainfall value.
4, need not self-recording paper, very little maintenance.
