The utility model discloses a pressure type rain gauge, which comprises a rain catcher (1). A pressure sensor (2) is arranged at the bottom of the inner chamber of the device (1), and the pressure sensor (2) is connected with the controller (3) through a data line; the pressure sensor (2) is a gauge pressure sensor. The utility model adopts a rain receiver with a standard caliber, and accurately observes the precipitation in real time by measuring the pressure at the bottom of the inner chamber of the rain receiver in real time and transferring the obtained data to the controller for calculation. Realize the storage, display and transmission functions of metering data; and have the characteristics of simple structure, low cost and wide application range, and are suitable for popularization and use.
Description
Technical field
The utility model relates to the rainfall metering outfit, specifically departments such as a kind of meteorology and the hydrology pressure type rain gage that is used for measuring the amount of rainfall.
Background technology
At present, both at home and abroad traditional udometer mainly adopts three kinds of forms: the first is with a leak formula iron sheet rain receiver processed, the udometer that glass cylinder is formed, this kind udometer is subjected to man's activity big, be easy to generate data error, and rain receiver employing ironwork, get rusty easily, tenure of use is limited, needs often to change; It two is that funneling rain receiver connects a plastic catheter, rainwater is introduced indoor, the mode that measures the amount of rainfall again, the plastic tube of this kind udometer tans by the sun to break easily throughout the year and causes rainwater to overflow, and udometer adopts glass to make, easily artificial the damage; It three is the modes of observing and predicting of tipping bucket type udometer, and this kind udometer because tipping bucket can be subjected to inertia effect, somersault occurs when rainfall intensity is big, causes measured value to increase.Simultaneously above-mentioned udometer does not have the modes such as storage, demonstration, transmission of continuous data; And because the structure limitation of instrument itself is prone to the inaccurate situation of measurement.
The utility model content
The purpose of this utility model is the defective at prior art, provide a kind of simple in structure, cost is low and measure promptly and accurately the pressure type rain gage.
The purpose of this utility model solves by the following technical programs:
A kind of pressure type rain gage comprises rain receiver, it is characterized in that described rain receiver is the cylinder mode that internal diameter is 200mm, and the intracavity bottom of rain receiver is provided with pressure transducer, and pressure transducer links to each other with controller by data line.
Described pressure transducer is gauge pressure transducer.
Described rain receiver adopts duroplasts to make.
The utility model has following advantage compared to existing technology:
The utility model adopts the rain receiver of standard bore, and by the pressure of rain receiver intracavity bottom being measured in real time and the data that obtain being passed to the mode that controller carries out computing quantity of precipitation being carried out real-time monitored accurately, controller also can be realized storage, demonstration and the propagation function of continuous data.
The utlity model has simple in structure, cost is low and advantage of wide range of application, suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: the 1-rain receiver; The 2-pressure transducer; The 3-controller.
Embodiment
Be further described below in conjunction with accompanying drawing and the utility model of embodiment.
As shown in Figure 1: a kind of pressure type rain gage, comprise the rain receiver 1 that duroplasts is made, and rain receiver 1 is the drum type brake normal structure that internal diameter is 200mm, is placed with pressure transducer 2 at the intracavity bottom of rain receiver 1, and pressure transducer 2 links to each other with controller 3 by data line; Wherein pressure transducer 2 is gauge pressure transducer.
The utility model adopts the rain receiver 1 of standard bore, and by the pressure of rain receiver 1 intracavity bottom being measured in real time and the data that obtain being passed to the mode that controller 3 carries out computing quantity of precipitation is carried out real-time monitored accurately, prior built-in computing formula in the controller 3: H=P/ ρ g, wherein ρ=1.0kg/m
3, g=9.8N/kg, namely the product of ρ g is a steady state value, therefore the pressure P that obtains in real time according to pressure transducer 2 can directly calculate quantity of precipitation H.Controller 3 also can be realized storage, demonstration and the propagation function of continuous data in addition; And have simple in structure, cost is low and advantage of wide range of application, suitable promoting the use of.
The technology that the utility model does not relate to all can be realized by prior art.
