Based on the embodiments in the present invention, all other embodiments of the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
Examples
As shown in fig. 1 and 2, the present embodiment provides a rain gauge capable of measuring surface runoff, which may include: the water collecting device 1 is arranged on the ground surface 6 and is provided with a corresponding water collecting area for collecting rainwater and surface runoff; the drainage device 2 is buried in the soil on the ground, is connected with the water collecting device 1 and is suitable for leading collected rainwater or surface runoff into the detection device 3; the detection device 3 is suitable for respectively detecting precipitation and surface runoff; the attitude detection module is used for detecting the embedding attitude of the rain gauge; and the processor module is electrically connected with the detection device 3 and the attitude detection module and compensates the detected surface runoff data according to the embedded attitude.
The rain gauge realizes the collection of rainwater and surface runoff through the water collecting device 1, realizes the function of detecting rainfall and surface runoff through the detecting device 3, achieves the effect that the rainfall and the surface runoff can be monitored simultaneously, can effectively compensate the surface runoff data by combining the embedding posture, and improves the accuracy of the surface runoff detection data.
In the present embodiment, the water collecting device 1 includes: a rainwater collection area 11 and a runoff collection area 12; the rainwater collecting area 11 is a platform part, and a runoff collecting part 121 is arranged in the runoff collecting area 12; the platform part and the runoff collecting part 121 are of an integrated structure, and have the advantages of small structure and flexible installation; the platform part is provided with a rainfall funnel 111; in order to prevent rainwater on the surface of the platform part from entering the rainwater funnel 111, the opening edge of the rainwater funnel 111 is provided with a rainwater discharge groove 112, and the rainwater discharge groove 112 extends toward the edge of the platform part to form a drainage channel to be discharged to the outside of the water collecting device 1.

As shown in fig. 3, when the ground surface 6 has a certain slope α and the installation inclination angle corresponding to the rain gauge is also α, due to the fact that the inertia effect of the slope water flow is too large, a part of the slope water flow F rushes through the surface of the runoff water collection area as shown in F1 in fig. 3, at this time, the amount of water actually entering the runoff water collection area is greatly different from the horizontal burying condition of the surface runoff monitoring unit, and it is highly likely that the slope water flow rushes through the runoff water inlet 123, so that the amount of water actually entering the runoff water inlet 123 is not increased according to the expected condition, and only a part of the water enters the runoff water inlet 123, as shown in F2, and accurate surface runoff data cannot be obtained.
Therefore, the inclination angle of the rain gauge is detected by the posture detection module; the processor module compensates the surface runoff according to the inclination angle so as to obtain actual flow data of the surface runoff under the slope condition.
The corresponding relation between the runoff compensation coefficient k and the embedded inclination angle of the rain gauge and the actual surface runoff can be obtained through a limited experiment, and a database is established. And multiplying the actually measured surface runoff by the runoff compensation coefficient to obtain the actual flow data F of the surface runoff.
| Mounting inclination angle alpha | Flow compensation coefficient k | Surface runoff F2 |
| Attitude detection module actual measurement | Obtained from experimental data, in particular, values of coefficients corresponding to particular flow rates, inclination angles obtained in the experiment | Obtained by actual measurement |
The actual flow data is F = k × F2.
