Description

A kind of rain meter suitable for heavy rainfall
Technical field
The utility model relates to a kind of rainfall gauge, especially a kind of rain meter suitable for heavy rainfall belongs to meteorology The technical field of monitoring.
Background technique
Precipitation is the significant process of global water and energy circulation, due to having led to it with violent spatial-temporal characteristics As one of the meteorological element for being most difficult to observe at present.
Currently, there are many ways to measurement precipitation, rainfall gauge is often meteorological as a kind of direct Rainfall estimation instrument Scholar and hydrologist are used to measure the precipitation in somewhere in a period of time.There are many kinds for rainfall gauge in the prior art, often Such as tipping-bucket rain-gauge, siphon rainfall recorder seen.
A kind of instrument of the tipping-bucket rain-gauge as measurement rainfall can inevitably go out due to designing defect itself Existing error.When heavy rainfall, rainfall impact force can be such that tipping bucket overturns in advance, cause measurement result bigger than normal, and rainfall intensity is bigger, accidentally Difference is bigger, is not suitable for heavy rainfall.
Siphon rainfall recorder is made of water container, float-type, siphon pipe, recording clock, water-storing bottle etc..Siphon pipe is not easy clearly It washes, installation trouble, and is easy to happen failure, will lead to biggish measurement error, need often to be checked.
Utility model content
Purpose of utility model: in view of the above problems, the object of the present invention is to provide a kind of suitable for the new of heavy rainfall Type rainfall gauge also can accurately measure the amount of rainfall in heavy rainfall weather.
Technical solution: a kind of rain meter suitable for heavy rainfall, including rainfall bucket, in the rainfall bucket from top to bottom It is disposed with rainfall sensing device, prestores container, measurement container, controller, the opening for prestoring container and measuring container Direction is identical as the opening direction of the rainfall bucket, and the three bottom offers discharge outlet, the row for prestoring container respectively The mouth of a river is corresponding with the measurement aperture position of container, and No.1 solenoid valve is provided in the discharge outlet for prestoring container, described It measuring and is provided with No. two solenoid valves in the discharge outlet of container, the rainfall sensing device is set to the opening of the rainfall bucket, Described to prestore outside of containers and rainfall bucket sealing fixation, the measurement container is fixed on the controller and sets inside it It is equipped with liquidometer, the controller is set to rainfall bucket bottom, and equipped with power module and counting on the controller Module, the rainfall sensing device, No.1 solenoid valve, No. two solenoid valves, liquidometers are associated with the controller signals respectively.
The principles of the present invention are: when rainfall, rainwater enters rain gage bucket, rainfall sensing device by the opening of rainfall bucket Rainfall signal is sent to controller, controller distinguishes signal control No.1 solenoid valve opening, No. two solenoid valves are closed, and rainfall passes through The discharge outlet for prestoring container flows into measurement container, makes the continuous rising for measuring liquid level in container, when liquid level rises to liquidometer When preset critical value, liquidometer sends pulse signal to controller, and controller signals control the closing of No.1 solenoid valve, No. two electricity Magnet valve is opened, and is started to discharge water and is recorded number by the counting module that it is carried, and after n seconds, signal controls No. two electricity to controller again Magnet valve is closed, No.1 solenoid valve is opened, again water inlet measurement, to repeat process of intaking-discharge water, and is recorded by counting module The number that discharges water in entire rainfall.After rainfall stops, rainfall sensing device sends rain and stops signal to controller, and controller is again The residual liquid level data in measurement container are collected by liquidometer, finally, the controller closing of signal control No.1 solenoid valve, two again Number solenoid valve opening discharges water, and signal controls No. two solenoid valves closings again after n second, and rainfall gauge is made to return back to original state.Drop During rain, rainfall value measured by rainfall gauge is that the preset liquid level critical value of liquidometer is put multiplied by what counting module was measured Waterside number is along with the residual liquid level in measurement container.Wherein, duration n second to discharge water can be according to measurement container and No. two electricity The aperture of magnet valve, which is tested, to be obtained.When the utility model collects rainfall, under the protection for prestoring container, measurement container not will receive by force The impact of rainfall is suitable for heavy rainfall weather.
