Weighing system includes the pan of steelyard and weighing sensor, weighing sensor links to each other with the pan of steelyard, the rainwater sensor is installed to the funnel lower extreme, the utility model discloses measuring accuracy is high, and simple structure can reduce and overhaul the number of times, suitable using widely.
Description
Technical field
The utility model relates to rainwater field of measuring technique, particularly relates to a kind of weighing type rain gauge of tipping bucket drainage pattern.
Background technology
Rain gage is a kind of instrument of the quantity of precipitation being used for measuring somewhere in a period of time, and the rain gage used at present is generally divided into Weighing type and tipping bucket type two kinds.Tipping-bucket rain-gauge, with left and right tipping bucket, namely overturns after the quantity of precipitation in a tipping bucket reaches the counterweight of tipping bucket, and another tipping bucket starts water receiving and overturns and so forth, calculates quantity of precipitation by calculating tipping bucket upset number of times in certain hour.Weighing type rain gauge utilizes a container attaching rainwater, utilizes weighing apparatus to calculate the rainwater weight of attaching in certain hour, can obtain quantity of precipitation through conversion.Tipping-bucket rain-gauge, due to tipping bucket mechanical axis viscous, tipping bucket indoor institute rain will be toppled over and totally need the time longer, and each residual water yield is inconsistent, have impact on the accuracy of measurement at tipping bucket.Tipping-bucket rain-gauge flows to tipping bucket again in order to the funnel Accumulated Rainwater improving precision and need bore less, and the little funnel of bore, easily by blockings such as foreign material sandstone, causes rain gage to lose efficacy.Weighing type rain gauge is owing to lacking drain function, and can only utilize bucket splendid attire rainwater, the bucket after filling can reach 20 kilogram weights, differentiate faint rainfall amount very high for the accuracy requirement of system, causes the cost of weighing type rain gauge higher.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing equipment, the utility model provides a kind of will weighing and to be combined with tipping bucket, and the timely draining of energy also ensures the weighing type rain gauge of the tipping bucket drainage pattern of measuring accuracy.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of tipping bucket drainage type weighing rain gauge, comprise weighing system, tipping bucket bracing frame, tipping bucket and funnel, described tipping bucket is arranged on below funnel, it is characterized in that: the tipping bucket bracing frame that described tipping bucket is installed by bottom is connected with weighing system, in the water delivering orifice of described tipping bucket, be provided with residual water aqua storage tank.
Wherein, described residual water aqua storage tank is curved inwardly by water delivering orifice and is formed.
Wherein, the water delivering orifice section shape of described tipping bucket can have arc, square, prismatic, infolding shape, many prismatics.
Wherein, described weighing system comprises the scale pan and LOAD CELLS, and described LOAD CELLS is connected with the scale pan.
As the further improvement of such scheme, described funnel lower end is provided with rain sensor.
The beneficial effects of the utility model:
The weighing type rain gauge of a kind of tipping bucket drainage pattern of the utility model, adopts tipping bucket and weighs the structure combined, and the draining in time of tipping bucket energy, ensures that the weight range measured is less, ensure measuring accuracy further.The change of tipping bucket water delivering orifice shape makes tipping bucket after toppling over rainwater, deliberately can retain a bit residual water, to ensure the end that is swift in motion toppling over rainwater, improve measuring accuracy.The utility model structure is simple, is suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is the utility model preferred embodiment structural representation;
Fig. 2 to Fig. 6 is the tipping bucket water delivering orifice section shape schematic diagram of the better different embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
With reference to accompanying drawing 1 to accompanying drawing 6, the weighing type rain gauge of a kind of tipping bucket drainage pattern of the utility model, comprise weighing system, tipping bucket bracing frame 4, tipping bucket 3 and funnel 1, the tipping bucket bracing frame 4 that described tipping bucket 3 is installed by bottom is connected with weighing system, residual water aqua storage tank is provided with in the water delivering orifice 8 of described tipping bucket 3, described residual water aqua storage tank is curved inwardly by water delivering orifice 8 and is formed, with reference to accompanying drawing 2 to accompanying drawing 6, tipping bucket water delivering orifice 8 section shape of different embodiment is respectively arc, square, prismatic, infolding shape, many prismatics.Described weighing system comprises the scale pan 5 and LOAD CELLS 6, described LOAD CELLS 6 is connected with the scale pan 5, described LOAD CELLS measures the total weight of the scale pan, tipping bucket bracing frame, tipping bucket and rainwater, described tipping bucket 3 is arranged on below funnel 1, described funnel 1 lower end is provided with rain sensor 9, and weighing system is fixed on pedestal 7.
Rainwater flows in tipping bucket 3 after funnel 1 place collects, central dividing plate 2 is divided into two tipping bucket rooms tipping bucket 1, rainwater flows into a tipping bucket room tailheaviness and shifts, when the indoor rainwater weight of this tipping bucket is greater than setting weight, tipping bucket 3 loses original balance and is toppled over away by rainwater, and then rainwater flows into another tipping bucket room, when rainwater weight is greater than setting weight, again there is center of gravity transfer cause out of trim and rainwater is toppled over away, so go round and begin again.Described tipping bucket drainage type weighing rain gauge can not stop when rain flows into stir action.The water delivering orifice 8 of described tipping bucket 3 is provided with the residual water aqua storage tank that water delivering orifice 8 is bent to form, this curved design deliberately retains the quantity of residual of non-quantitative after making tipping bucket 3 topple over rainwater, and can ensure that the action toppling over rainwater can terminate rapidly, when data acquisition, this residual amount is counted in rain gage original weight, facilitates the calculating of rainfall data.The funnel 1 that the weighing type rain gauge of described tipping bucket drainage pattern collects current no longer requires minor diameter, and described funnel 1 can, by enlarged-diameter to 6-8mm, can effectively prevent foreign material from blocking funnel.Described rain sensor 9 is arranged on funnel 1 lower end, and its effect prevents LOAD CELLS 6 from reporting by mistake when little rainfall or temperature significantly change.In the rain gage course of work, weight data is constantly collected and stored in the data-carrier store of LOAD CELLS, the software of described LOAD CELLS 6 completes the process of image data, the packet gathered contains temperature compensation and the data breakpoint process of tipping bucket moment of sensor, ensure that the accuracy of data.
More than that better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
