Abstract
The utility model provides a twice measuring rainfall device. The device is characterized in that the rainfall which is lower than 2 mm during the rainfall at one time is only measured by a first sensitive overturning skip with a small measuring value of a measuring mechanism, and an electrical signal is output to be carried out with the recording. The rainfall which is larger than 2 mm is measured by the first overturning skip, and then enters a second overturning skip with a large measuring value to be measured, and then the electrical signal is also output to be carried out with the recording. Therefore, the measuring accumulated error of the first sensitive overturning skip with a small measuring value can be eliminated, and thus, the purposes of both measuring out the micro rainfall, and raising the measurement precision of the rainfall with a large rainfall intensity can be achieved.
Description
The utility model relates to the instrument of meteorological observation, the tipping-bucket rain-gauge sensor.
The metering mechanism of the sensor of existing tipping-bucket rain-gauge, although of all kinds in form, and in fact all be to have only a tipping bucket to play the metering effect.Requiring resolving power is the tipping-bucket rain-gauge of a measurement structure of 0.1 millimeter rainfall, also can't reach the rainfall degree at present and be not more than and measure rainfall in the 4mm/ branch scope, measuring error is no more than ± and 3% level.Therefore, though tipping-bucket rain-gauge has simple in structure, reliable operation, be convenient to wired or wireless electric signal and be delivered to many-sided advantages such as distant place register writes down, yet, because measuring error is too big, measuring accuracy is not by far up to the mark, and this rain gage great majority are only measured rain condition the unmanned weather station and used.Now, the measuring accuracy of the tipping-bucket rain-gauge of theoretical verified once metering can not reach the level that climatology requires.
The purpose of this utility model is the tipping-bucket rain-gauge sensing device that a kind of high-precision secondary measurement will be provided.
The purpose of this utility model is achieved in that whole metering mechanism is placed in the tube of metal garden, collects rainwater by collection rain bucket (15).The rainwater of collecting enters the bidirectional measuring tipping bucket (2) of metering mechanism, and the rainwater of turning down through the bidirectional measuring tipping bucket enters unidirectional metering tipping bucket (6) again.Each tipping bucket configuration one cover Armco magnetic iron (10) and (9) steel spring pipe, whenever stirring once all has electric signal to export recording mechanism to.
The rain gage sensing device that the utility model provides, not only improved the sensitivity (0.05mm just has counting, record reflection) of measuring trace of rainfall, and can improve the mensuration precision effectively, rainfall density is not more than in the 4mm/ branch scope, measuring error is no more than ± and 1%, reached the standard of GB high-class product grade.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is udometric front view
Fig. 2 is the side view of Fig. 1
The utility model is hung in the common rainfall garden tube (13) by link plate (12).During rainfall, collect rainwater by the collection rain bucket (15) of rain gage bucket, rainwater enters Bidirectional tipping (2) right side through upper hopper (14), and tipping bucket (2) can be around axle (18) left-right rotation.When amount of rainfall reached 0.05mm, tipping bucket was toppled over to the right; Rainwater improves the left side into tipping bucket (2), and when amount of rainfall reached 0.05mm, tipping bucket was toppled over left.Regulate timing screw (1) and can change amount of rainfall.The rainwater warp that tipping bucket (2) both sides are turned down funnel (3) down enters temporary bucket (4), and temporary struggle against (4) can be rotated around axle (16).The unidirectional tipping bucket (6) that rainwater is let slip a remark and entered metering mechanism through temporary bucket again.Tipping bucket (6) counterbalance (8) plays the counterweight function of suitable balance, and when amount of rainfall reached 2mm, tipping bucket (6) fell to the left, and when corner reached the 80 degree left and right sides, rainwater had all fallen in the bucket.Under the weight effect of counterweight, tipping bucket (6) back overturns, and restores to the original state.The amount of rainfall of counterweight fine setting (7) scalable tipping bucket (6).In tipping bucket (6) switching process left, the driving lever (5) of the temporary bucket of the roller on the tipping bucket (11) collision, temporary bucket is toppled over to the right, the rainwater that following funnel (3) gets off is temporary in the bucket (4), tipping bucket is to the right in the turning course, roller (11) collides driving lever (5) again, makes the temporary extensive original state of turning left back that struggles against, and enters again in the tipping bucket (6) through the temporary rainwater that struggles against.Single, double to tipping bucket (2) with Armco magnetic iron (10) is housed respectively above (6), steel spring pipe (9) is housed on the support, corresponding with it.The every overturning of tipping bucket is once exported an electric signal to counting, recording mechanism.
Claims (3)
1, a kind of tipping bucket type secondary measurement rain gage sensor, form by collection rain bucket, tipping bucket, output electric signaling device, of the present utility model being characterised in that, the rainwater of turning down through bidirectional measuring tipping bucket (2) enters unidirectional metering tipping bucket (6) again, and two tipping buckets all have device (9) and (10) of output electric signal.
2, rain gage sensor according to claim 1, it is characterized in that being equipped with on the unidirectional metering tipping bucket (6) roller (11), adorn a driving lever (5) on the temporary bucket (4), roller (11) collision driving lever (5) makes temporary bucket toward reverse turn during unidirectional metering tipping bucket (6) upset.
3, rain sensor according to claim 1 is characterized in that, the variable of unidirectional metering tipping bucket (6) is greater than the variable of bidirectional measuring tipping bucket (2).
