Abstract
The utility model provides a rain gauge, which is mainly composed of a shell body, a water receiving device, a funnel, a float chamber, a float, a recorder, etc. The utility model is characterized in that a water inlet of the float chamber (3) is provided with a water feeding electromagnetic valve (5), and a water outlet of the float chamber (3) is provided with a draining electromagnetic valve (6); the working stroke of the float (4) is provided with an upper limit switch (7) and a lower limit switch (8), wherein, the water feeding electromagnetic valve (5) is a normally opened magnetic valve, the draining electromagnetic valve (6) is a normally closed electromagnetic valve, and the upper limit switch and the lower limit switch are connected with the working circuits of the water feeding electromagnetic valve and the draining electromagnetic valve.
Description
The utility model relates to a kind of rain gage.
Existing rain gage is mainly by raingauge receiver, funnel, float chamber, float, recording clock, compositions such as U trap, the rainwater that raingauge receiver receives flows into float chamber through funnel, rising drive float rising along with water level in the float chamber, the rising of float drives recording clock record rainfall, U trap begins to put the water in the float chamber when float rises to certain altitude, the process that discharges water approximately needs more than ten second, discharge water finish the back float chamber begin the water storage of a new round again, float also drives the record that recording clock begins a new round, but in the process that U trap discharges water through raingauge receiver, the rainwater that funnel flows into float chamber but flows out float chamber without being recorded directly through U trap, and the loss of this part rainwater causes udometric measuring error bigger.
The purpose of this utility model provides the less rain gage of a kind of measuring error.
To achieve these goals, technical solution of the present utility model is such: a kind of rain gage, mainly constitute by housing, raingauge receiver, funnel, float chamber, float, registering instrument etc., wherein the water inlet at float chamber is provided with entering water electromagnetic valve, water delivering orifice at float chamber is provided with drain solenoid valve, upper limit position switch and lower position switch are set on the impulse stroke of float, wherein entering water electromagnetic valve is a normally open solenoid valve, drain solenoid valve is a normally closed solenoid valve, and the upper and lower limit bit switch is being controlled the operating circuit that connects entering water electromagnetic valve and drain solenoid valve.
Owing to set up in the above-mentioned technical solution, lower position switch and water inlet, drain solenoid valve, when float chamber in water storage, in the process that float rises, entering water electromagnetic valve is often opened, drain solenoid valve is normally closed, Nei rainwater goes on record through the motion of float during this period of time, run into upper limit position switch to make solenoid valve operating circuit closure be the entering water electromagnetic valve closure when float rises to the limes superiors position, drain solenoid valve is opened, the rainwater of float chamber is through the drain solenoid valve emptying, the rainwater that is connect in evacuation procedure outside float chamber, has therefore been avoided measuring error by the entering water electromagnetic valve retaining.Also decline synchronously of discharge float along with rainwater, the solenoid valve operating circuit is disconnected is that entering water electromagnetic valve is opened, the drain solenoid valve closure when float drops to the smallest limit position and runs into lower position switch, at this moment what connect in evacuation procedure is flowed into float chamber again by the entering water electromagnetic valve retaining rainwater float chamber outside and goes on record, and has therefore realized not having free from error rainwater measurement.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is a udometric structure principle chart provided by the utility model.
Wherein: 1, raingauge receiver; 2, funnel; 3, float chamber; 4, float; 5, entering water electromagnetic valve; 6, drain solenoid valve; 7, upper limit position switch; 8, lower position switch; 9, induction ruler; 10, sensor; 11, signal Processing electrical equipment; 12, display.
As shown in Figure 1, when rainwater is received by raingauge receiver 1 and flows in the process of float chamber 3 through funnel 2, entering water electromagnetic valve 5 is in normally open, drain solenoid valve 6 is in normally off, collected rainwater is recorded instrument through the upward movement of float 4 and notes in during this period of time, even make solenoid valve operating circuit closure entering water electromagnetic valve 5 closures when float 4 rises to the limes superiors position and promotes upper limit position switch 7, drain solenoid valve 6 is opened, rainwater in the float chamber 3 is discharged through drain solenoid valve 6, the rainwater that raingauge receiver 1 is connect in evacuation procedure is kept off outside float chamber 3 by entering water electromagnetic valve 5, along with rainwater is discharged from outside the float chamber 3, float 4 also descends synchronously, even solenoid valve operating circuit disconnection entering water electromagnetic valve 5 is opened when float 4 drops to the smallest limit position and promotes lower position switch 8, drain solenoid valve 6 closures, float chamber 3 begins to receive rainwater again, float 4 rises thereupon and drives registering instrument record rainfall, so repeats the purpose that above process can realize accurately measuring amount of rainfall.
In order to make udometric recording means more accurate, advanced, the utility model also adopts recording means as shown in Figure 1 to substitute original recording clock, promptly by fixed installation induction ruler 9 on float 4, induction ruler 9 and the motion of float 4 synchronization liftings, near induction ruler 9 sensor 10 is housed fixedly, sensor 10 maintains static, the motion of float 4 is being with the relative sensors 10 of induction ruler 9 to produce displacements, and the size of displacement is converted into the measurement data that signal processing circuit 11 that the electric signal warp links to each other with sensor 10 and display 12 are expressed as rainwater.
Sensor 10 in Fig. 1 adopts capacitor grid transducer, can certainly adopt the sensor of other type.
