Abstract
The invention discloses a rainfall monitoring device which comprises a water storage chamber (1) and a rain cup (2) communicated with the water storage chamber (1). A floating block (4) is arranged in the water storage chamber (1), an induction pole plate (5) is arranged on the floating block (4) and provided with a capacitive displacement sensor (6), the capacitive displacement sensor (6) is connected with a signal processing controller (7) which is connected with a displayer (8), a drain pipe is arranged on the bottom of the water storage chamber (1) and provided with a drain solenoid valve (9), and a water inlet solenoid valve (10) is arranged on a communicating pipeline between the water storage chamber (1) and the rain cup (2). By the adoption of the structure, too much or too little rainwater can be prevented from existing in the water storage chamber, the fact that floating block is always in a floating state can be ensured, the increasing amount of the rainwater in the water storage chamber is identical to the upward floating amount of the floating block, and thus measuring precision is guaranteed.
Description
Technical field
The present invention relates to the rainfall monitoring field, specifically a kind of rain fall monitor.
Background technology
Precipitation measurement comprises the observation of quantity of precipitation and precipitation intensity.Quantity of precipitation referred in a certain period, dropped to ground liquid state or solid-state (after melting) precipitation, the degree of depth that accumulates at surface level without evaporation, infiltration and loss from sky.Quantity of precipitation is got a decimal take mm as unit.Weather station observation per minute, the time, the daily precipitation amount.The amount of pure mist, dew, frost, freezing fog, blowing snow, ice needle is by processing without precipitation, when itself and precipitation are accompanied its amount of also not deducting when seeing.Precipitation intensity refers to the quantity of precipitation of unit interval, usually measures the maximum precipitation in 5 minutes, 10 minutes and 1 hour.
At present, a kind of rainwater measurement mechanism based on bivalve capacitance-grid type rain sensor is arranged, mainly comprise adaptor, water storage room, floating block, induction pole plate, signal processing controller and display, its principle is to utilize in the water storage room floating block to answer pole plate with rainfall rising dynamic, make and hold the electric capacitance change that the grid displacement transducer produces, the principle through being converted to displacement measurement records quantity of precipitation.This metering system is directly perceived, and precision is high, but has a problem, just begun when the rainwater in the water storage room is very few, floating block can't be floating, along with the increase floating block of rainfall just slowly floats, this moment, corresponding amount of floating was not the recruitment of rainwater, therefore had certain error.
Summary of the invention
The invention provides a kind of rain fall monitor, solved in the past based on the rainwater measurement mechanism of bivalve capacitance-grid type rain sensor when measuring rainfall, it is very few that rainwater easily appears in the water storage room, bring the problem of error to measurement.
The present invention is that the technical solution problem is achieved through the following technical solutions: the rain cup that comprises water storage room and be communicated with water storage room, be provided with floating block in the water storage room, floating block is provided with the induction pole plate, the induction pole plate is provided with and holds the grid displacement transducer, hold on the grid displacement transducer and be connected with signal processing controller, be connected with display on the signal processing controller, described water storage room bottom is provided with drainpipe, described drainpipe is provided with drain solenoid valve, and the connecting pipe between described water storage room and the rain cup is provided with entering water electromagnetic valve.Rainwater enters in the water storage room by the rain cup, and along with increasing of rainwater, floating block slowly floats, and the induction pole plate is floating slowly also, make and hold the electric capacitance change that the grid displacement transducer produces, through being converted to displacement measurement, and after signal is processed output on display; After measurement was complete, drain solenoid valve can be opened automatically, and the rainwater in the water storage room is discharged a part, in order to measuring next time, when certain position is arrived in water storage room's draining, drain solenoid valve meeting autoshutdown, avoid the rainwater in the water storage room very few situation to occur, make floating block be in floating state always; When the excessive rainfall in the water storage room, entering water electromagnetic valve also can autoshutdown.
Further, the shape of cross section of described rain cup is circular, and the diameter length on rain cup top is greater than the diameter length of bottom.Up big and down small structure is conducive to rainwater-collecting, makes simultaneously fast as far as possible the entering in the water storage room of rainwater.
Further, the bottom of described rain cup is communicated with the side wall lower ends of water storage room.Rainwater in the rain cup as much as possible all enters in the water storage room, and what enter is the bottom of water storage room, can reduce like this rainwater concussion in the water storage room, avoids responding to pole plate and floats excessive.
Further, the top of described rain cup is provided with adaptor, and described adaptor is communicated with the rain cup.Adaptor mainly is for improving the rainwater-collecting effect.
Further, the top of described water storage room is provided with osculum, and the induction pole plate inserts in the water storage room by osculum, and is fixedly connected with floating block.Osculum can reduce the evaporation of rainwater, also the induction pole plate is had certain position-limiting action, prevents from responding to the pole plate double swerve, and the induction pole plate can only be moved up and down.
The present invention compared with prior art has the following advantages and beneficial effect: the present invention has increased entering water electromagnetic valve, drain solenoid valve by the basis at former rain measurement mechanism, avoided the rainwater in the water storage room too much or very few situation to occur, guarantee that floating block is in floating state all the time, make the rainwater recruitment in the water storage room consistent with the float-amount of floating block, thereby guarantee the precision of measurement.
