Problems solved by technology

However, each type of rain gauge has certain defects in accuracy or operability, and it is not perfect. For example, the measurement accuracy of the tipping bucket rain gauge is limited by the intensity of rainfall. The heavier the rain, the more inaccurate the measurement; and the siphon rain gauge The rain gauge needs frequent on-site record measurement and replacement of recording paper, which brings inconvenience to field monitoring; the ultrasonic rain gauge is affected by the density, concentration, temperature, pressure and other factors of the medium, and its measurement accuracy is relatively low. Low
In addition, various existing rain gauges are easily blocked by impurities during field use, thus affecting the accuracy of rainfall measurement.

Embodiment 1

[0016] Such as figure 1 As shown, the present invention includes a housing 1, a water container 3, a siphon 6 and a filter cover 7 installed on the top of the housing 1. A funnel 2 is also installed under the top opening of the housing 1, and the water container is connected below the funnel 2. 3; The bottom of the water container 3 is connected to a pressure sensor 4, the pressure sensor 4 is connected to the data collector, and a siphon 6 is also provided on the side of the water container 4. When it starts to rain, the external rainwater enters the water container through the funnel after passing through the top filter cover, and the water level in the water container gradually rises. When the rainfall reaches the height of the siphon point, the water in the water container will pass through the siphon tube. When the water is discharged, the water level in the water container will decrease accordingly. When it starts to rain and the rainfall does not reach the height of th...

Embodiment 2

[0018] This embodiment is preferably as follows on the basis of Embodiment 1: In order to avoid external debris from gathering on the filter cover and affecting the filtering effect of the filter cover, the filter cover 7 is a hemispherical structure with the spherical surface facing outwards to cover the entire housing 1 opening. Due to the hemispherical structure of the filter cover, the impurities falling on the filter cover are not easy to stack and can quickly fall to the ground, thus ensuring the filtering effect of the filter cover.

Embodiment 3

[0020] This embodiment is preferably as follows on the basis of the above embodiments: the housing 1 includes a top cover, a middle storage cavity and a base, wherein the cover, storage cavity and base are sequentially connected as an integral structure, The width of the cover body is larger than that of the containing cavity, and covers the entire containing cavity below. The cover body can protect the entire storage cavity, prevent rainwater from entering the gap formed by the storage cavity and the cover body, and ensure accurate measurement results.

[0021] Since the residual water column in the siphon will affect the accuracy of the measurement results, in order to ensure that the rain reaches the siphon point, it can siphon normally without dripping, and when the siphon is finished, there will be no remaining water column in the tube. The arc range is between 29°-31°.

[0022] The inner diameter range of the macro suction pipe 6 is between 6-7mm.

Abstract

The present invention discloses an improved pluviometer, comprising housing, a water container, a siphon and a filtering cover installed at the top of the housing. A funnel is arranged below the opening at the top within the housing, and the water container is located under the funnel and connected with the funnel; a pressure sensor is connected with the bottom of the water container and is connected with a data acquisition unit, and the siphon is arranged at the side of the water container. By employing the structure provided by the invention, the improved pluviometer has low power dissipation and high measurement accuracy, the remote transmission may be realized without blocking impurities, and the accuracy of the measurement is ensured.

Description

technical field [0001] The invention relates to the field of geological disaster monitoring, in particular to an improved rain gauge. Background technique [0002] my country is a mountainous country. Mountains, plateaus and hills account for 69% of the country's land area. A large number of geological disasters such as collapses, landslides and mudslides occur every year. One of the main inducing factors for disasters such as collapses, landslides and mudslides is rainfall. Therefore, how to obtain real-time and accurate rainfall data is particularly important for the early warning of geological disasters. The rain gauge is an instrument commonly used by meteorological and social departments to measure precipitation. It is generally divided into two methods: manual measurement and sensor measurement. . The sensor measurement can be subdivided into various types of rain gauges. However, each type of rain gauge has certain defects in accuracy or operability, and it is not per...
