Description

Pluviometer

Technical field

This utility model relates to rainwater detection, in particular it relates to a kind of pluviometer。

Background technology

Pluviometer be a kind of meteorologist and hydrologist for measuring the instrument of the precipitation in somewhere in a period of time, most pluviometer is all using millimeter as measuring unit, and sometimes measurement result also can using inch or centimetre as unit。Common are siphon rainfall recorder, weighing type rain gauge, tipping-bucket rain-gauge, solid rain-accumulating gauge, simple and easy pluviometer, numeral pluviometer etc., the frequency observed then can change according to different demands。

It is higher that existing pluviometer is primarily present when raining heavyly (rainfall > 4mm/ minute) error, and conventional tipping-bucket rain-gauge even cannot measure。

Utility model content

The purpose of this utility model is to provide a kind of pluviometer, and its detection more accurately, reliably, is measured wider。

To achieve these goals, this utility model provides a kind of pluviometer, including influent hopper, water inlet pipe, drain pipe, entering water electromagnetic valve, drain solenoid valve, water storage container and contactless liquid level sensor, the upper end of described water inlet pipe is connected to described influent hopper, lower end is connected to the bottom of described water storage container, described entering water electromagnetic valve is arranged on described water inlet pipe, described drain solenoid valve is arranged on described drain pipe, described drain pipe is connected to the bottom of described water storage container, and described contactless liquid level sensor is positioned at the top of described water storage container。

Preferably, described contactless liquid level sensor is supersonic level sensor or radar level transmitter。

Preferably, the lower tilt of described water inlet pipe is connected to the bottom of described water storage container。

Preferably, this pluviometer also includes shell, and described water storage container is positioned at the inside of this shell, and described influent hopper is connected on this shell, and described drain pipe is communicated to the outside of this shell。

In pluviometer of the present utility model, the lower end of water inlet pipe is connected to the bottom of water storage container, and therefore when water inlet, the liquid level in water storage container is substantially without fluctuation, thus testing result is more accurately and reliably。Additionally, water inlet pipe and outlet pipe are respectively provided with entering water electromagnetic valve and drain solenoid valve, when liquid level in water storage container reach a certain height, entering water electromagnetic valve can be automatically controlled close, drain solenoid valve is opened, being bled off by the Water in Rainwater Drainage collected in water storage container, therefore this pluviometer is applicable to the measurement of various rainfall scopes such as from light rain to extra torrential rain。

Other feature and advantage of the present utility model will be described in detail in detailed description of the invention part subsequently。

Accompanying drawing explanation

Accompanying drawing is used to offer and is further appreciated by of the present utility model, and constitutes a part for description, is used for explaining this utility model, but is not intended that restriction of the present utility model together with detailed description below。In the accompanying drawings:

Fig. 1 is the udometric structural representation that this utility model preferred implementation provides；

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail。It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains this utility model, it is not limited to this utility model。

This utility model relates to a kind of pluviometer, including influent hopper 1, water inlet pipe 7, drain pipe 8, entering water electromagnetic valve 3, drain solenoid valve 6, water storage container 5 and contactless liquid level sensor 4, the upper end of described water inlet pipe 7 is connected to described influent hopper 1, lower end is connected to the bottom of described water storage container 5, described entering water electromagnetic valve 3 is arranged on described water inlet pipe 7, described drain solenoid valve 6 is arranged on described drain pipe 8, described drain pipe 8 is connected to the bottom of described water storage container 5, and described contactless liquid level sensor 4 is positioned at the top of described water storage container 5。

In pluviometer of the present utility model, the lower end of water inlet pipe 7 is connected to the bottom of water storage container 5, and therefore when water inlet, the liquid level in water storage container 5 is substantially without fluctuation, thus testing result is more accurately and reliably。Additionally, water inlet pipe 7 and outlet pipe 8 are respectively provided with entering water electromagnetic valve 3 and drain solenoid valve 6, when liquid level in water storage container 5 reach a certain height, entering water electromagnetic valve 3 can be automatically controlled close, drain solenoid valve 6 is opened, being bled off by the Water in Rainwater Drainage collected in water storage container 5, therefore this pluviometer is applicable to the measurement of various rainfall scopes such as from light rain to extra torrential rain。

Preferably, contactless liquid level sensor 4 can be supersonic level sensor or radar level transmitter。

Preferably, the bottom of water inlet pipe 7 can tilt to be connected to the bottom of water storage container 5, therefore in water inlet pipe 7 will not water, measurement effect is more accurate。

It addition, pluviometer of the present utility model can also include shell 2, water storage container 5 is positioned at the inside of shell 2, and influent hopper 1 is connected on shell 2, and drain pipe 8 is communicated to the outside of shell 2。By this shell 2, it is possible to internal water storage container 5, contactless liquid level sensor 4, entering water electromagnetic valve 3 and drain solenoid valve 6 etc. are protected, and influent hopper 1 can also be affixed on shell 2。Drain pipe 8 is communicated to the outside of shell 2, and the rainwater in water storage container 5 is directly discharged to outside。

Preferred implementation of the present utility model is described in detail above in association with accompanying drawing; but; this utility model is not limited to the detail in above-mentioned embodiment; in technology concept of the present utility model; the technical solution of the utility model can being carried out multiple simple variant, these simple variant belong to protection domain of the present utility model。Additionally, can also carry out combination in any between various different embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally。
