Abstract
The invention discloses an equivalent-time rainfall rain sample meter, belongs to the fields of hydrology and meteorology and particularly relates to a device for measuring the rainfall according to period of time. The equivalent-time rainfall rain sample meter comprises a primary rain receiving hopper, a casing, a takeover tube, a secondary rain hopper, a water-dividing catheter, a stepped motor control device and a rainfall measuring cup, wherein the primary rain receiving hopper is inserted into the casing and is connected with the takeover tube; the secondary rain receiving hopper is arranged below the takeover tube; the lower part of the secondary rain receiving hopper is connected with the water-dividing catheter; two ends of the water-dividing catheter are closed; a downward-opening hole is arranged at the far end of the water-dividing catheter; and the rainfall measuring cup is arranged below the downward-opening hole. The invention has the advantages that: firstly, the equivalent-time division of rain can be realized by a stepping motor for the first time; and secondly, the time division is quite fine by replacing the rainfall measuring cups and shortening the each-step stay time of the stepping motor as long as the number of the rainfall measuring cups is enough.
Description
Technical field
The present invention waits period rainfall rain appearance meter to belong to the hydrology and meteorological field, relates in particular to a kind of device that measures the amount of rainfall at times and gather rain appearance.
Background technology
At present in meteorological and hydrology field; The rain gage that uses is generally tipping-bucket rain-gauge; Rainfall gets into tipping bucket through funnel, tumbles once behind the tipping bucket chengman rainwater, and the amount that tipping bucket fills with rainwater is confirmed; The number of times of tumbling of rain gage record tipping bucket writes down total rainfall (CN2562196) with this.Further, through the metering method of tipping bucket being improved and having been occurred: digital tilting bucket rain CN2070909; Precipitation station CN1455269 high precision tilting bucket rain.
The float-type rain gage is appearring again aspect the long-term self-recording rainfall amount; Mainly be to put float in the graduated cylinder; Precipitation converges in the graduated cylinder, and the graduated cylinder water level is different, promotes float and moves up and down; Be recorded on the recording chart and mainly comprise: (CN86205416) float-type rain gage, (CN2406229) rain gage of continuous working (CN2155025).Formed after further improving such as horizontal rain gage (CN2266139); Measuring cup type (CN2099323), digital integrated circuit telemetering rain ga(u)ge (CN2031105), hydrocone type pluviograph (CN2099323; CN87210894; CN2534565), the rain gage that water quality etc. are monitored simultaneously (CN2591649), bearing type rain gage (CN2553390).
Udometric pattern is varied, but still can not satisfy following two kinds of needs.
1, aspect meteorological, can't obtain rainfall value at times automatically.Rainfall value at times can be well understood to whole rainfall at regular intervals, for example the rainfall amount of 1h or 1min.The understanding of this numerical value can be understood the rainfall intensity of each period of rainfall exactly.
2, aspect the hydrology; The rainfall meeting of different periods has different isotopic contents; With separately sampling of one section rainfall; Can obtain isotopic content in the rain appearance after the dividing of whole rainfall by the period, in order to analyze the moisture source between different flush periods with conflux at times after the water body whereabouts, and then from the physical mechanism aspect partition problem of improvement current flux graph.
Summary of the invention
The present invention waits period rainfall rain appearance meter just according to above Demand Design, and its purpose is to provide a kind of rain gage, can obtain different time rainfall value at interval, obtains the rainwater sample of different precipitation period simultaneously.
Particularly the present invention waits the period rain glass to comprise: the one-level bucket for receiving rain, and shell, middle adapter, the secondary bucket for receiving rain divides water conduit, stepping motor control apparatus, rain cup; Wherein the one-level bucket for receiving rain inserts shell and joins with middle adapter, and middle adapter below is the secondary bucket for receiving rain, and secondary bucket for receiving rain below joins with dividing water conduit, divides the water conduit closed at both ends, and far-end has a downward bend pipe, and its below is a rain cup.
The water conduit below was connected with stepping motor control apparatus in described minute.
Described stepping motor control apparatus comprises: stepper motor, controllor for step-by-step motor, single-chip microcomputer, power supply adaptor.
Described power supply adaptor comprises: transformer and accumulator.
Described rain cup is a plurality of, changes its size and number as required, and the size of rain cup and the control mode of number are that all rain cups are formed centrally a circle in rain glass, divide the downward bend pipe of water conduit far-end to face each rain cup.
Working method particularly of the present invention is following:
A, user select bigger rain cup or the less higher rain cup of precision according to the needs of oneself;
B, select time set that angle step pitch and per step of stepper motor stop in described single-chip microcomputer according to selected rain cup with to the requirement of rainfall segmentation;
C, when beginning to rain, start single-chip microcomputer in motor program, the MCU driving controllor for step-by-step motor turned round according to preset angle step pitch and per residence time in step;
D, stepping motor control apparatus drive and divide the water conduit rotation, divide water conduit in each rain cup, to fill rainwater by periods such as the time ground that is provided with;
When E, rainfall finished or do not finish, the rainwater appearance of taking out in the rain cup was carried out quantitatively or physicochemical analysis;
F, replacing rain cup finish up to rainfall.
The present invention has following advantage:
1, first through utilize stepper motor driven mode realize rainfall etc. the period cut apart;
2, as long as the quantity of rain cup is enough, through changing the rain cup and the per residence time in step that shortens stepper motor, this time cut apart can accomplish very fine;
3, for utilizing isotope assay, confluxing situation about analyzing at times provides rainfall data basis.
