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, the various existing rain gauges can only realize the function of rainfall measurement. If an internal failure occurs, it is not easy to repair, and the entire rain gauge can only be replaced, and the cost of use is relatively high.

Embodiment 1

[0018] Such as figure 1 As shown, the present invention includes a housing 1, a water container 3, a siphon 6 and a camera 7, the internal water container 3 of the housing 1 is connected to the top of the housing 1 through a funnel 2, and the water container 3 The pressure sensor 4 is also connected below; the pressure sensor 4 and the camera 7 are connected to the data collector 5 inside the casing 1;

[0019] When it starts to rain, the external rainwater hits the top of the shell, enters the water container through the funnel, 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 flow through the siphon. 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 the siphon point, the rainfall during this period can be converted from the voltage data transmitted by the ...

Embodiment 2

[0021] This embodiment is preferably as follows on the basis of Embodiment 1: In order to ensure that the rain gauge can work stably in the field, supply sufficient electric energy, and realize normal operation, the data collector 5 is also connected to a solar panel 8 .

[0022] In order to facilitate the observation of changes in information such as the water level inside the rain gauge from the outside, a liquid level line is also provided on the inspection port 9 .

Embodiment 3

[0024] 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.

[0025] 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°.

[0026] The camera 7 is a camera 7 that rotates in all directions and has no dead angle. It can more...

Abstract

The invention discloses a rainfall detection device which comprises a housing, a water container, a siphon and a camera. The water container inside the housing is connected with the top of the housing through a funnel, and the lower portion of the water container is further connected with a pressure sensor. The pressure sensor and the camera are simultaneously connected to a data acquirer located inside the housing. An access hole is further formed in the side face of the housing. By the adoption of the structure, the rainfall change situation can be detected, the change situation of a surrounding geological disaster can be also monitored, and transfer is performed remotely to facilitate later reasonable taking of recourse measures according to the situations of the rainfall and the surrounding geological disaster. In addition, due to the fact that the access hole is further specially formed for the rainfall detection device, later local overhaul is facilitated, and the using cost is reduced.

Description

technical field [0001] The invention relates to the field of geological disaster monitoring, in particular to a rainfall detection device. 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 no...
