Abstract
The utility model belongs to the field of hydrology and meteorology and relates to a rain gauge at an equal time interval, in particular to a device for measuring rainfall in different time intervals. The rain gauge comprises a primary rain bucket, a case, a middle connecting pipe, a secondary rain bucket, a water distribution conduit, a stepping motor control device and a rain glass, wherein the primary rain bucket is inserted into the case and connected with the middle connecting pipe, the secondary rain bucket is arranged below the middle connecting pipe, the lower part of the secondary rain bucket is connected with the water distribution conduit, both ends of the water distribution conduit are closed, a downward opening is arranged at the remote end, and the rain glass is arranged below the opening. The rain gauge has the advantages that: 1. the equal time interval division of the rainfall is realized through the manner of a stepping motor; and 2. As long as the rain glasses are sufficient, the time division can be quite precise by replacing the rain glass and shortening the retention time of each step of the stepping motor.

Background technology
At present in meteorological and hydrology field, the rain gage that uses is generally tipping-bucket rain-gauge, rainfall enters tipping bucket by a funnel, tumble once behind the tipping bucket chengman rainwater, the amount that tipping bucket fills with rainwater is determined, the number of times of tumbling of rain gage record tipping bucket writes down total rainfall (CN2562196) with this.Further, by 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, graduated cylinder water level difference, the promotion float 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.This numerical value obtain the rainfall intensity that can understand 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 sample after the dividing of whole rainfall by the period, in order to analyze the moisture source between different flush periods and conflux at times after the water body whereabouts, and then improve the partition problem of current flux graph from the physical mechanism aspect.
Summary of the invention
Period rainfall rain sample meters such as the utility model are 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, obtain the rainwater sample of different precipitation period simultaneously.
Particularly period rain glass such as the utility model comprises: 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 hole of opening downwards, 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 be, all rain cups are formed centrally a circle in rain glass, and the hole of dividing the water conduit far-end to open downwards faces each rain cup.
The utlity model has following advantage:
1, first by utilize stepper motor driven mode realize rainfall etc. the period cut apart;
2, as long as the quantity of rain cup is enough, by changing rain cup and shorten per residence time in step of 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.
