Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

Referring to Fig. 1, the present embodiment adopts the following technical solutions: a rainfall runoff measuring device, comprising a rainwater sampling tank 1, a runoff flow transmitter 2, a multi-parameter data collector 3, a display 4 and a control button 5 and a solar power storage Device 6, a plurality of rainwater sampling tanks 1 are all connected to the multi-parameter data collector 3 through the runoff flow transmitter 2, and the multi-parameter data collector 3 is provided with a display 4 and a control button 5. The multi-parameter data collector 3 is also provided with a solar energy storage device 6.

It should be noted that a weighing rain gauge 11 is arranged at the bottom of the rainwater sampling tank 1 .

In addition, the rainwater sampling tank 1 is a stainless steel tank.

In this embodiment, multiple samples are taken from the rainwater sampling tank 1 for runoff measurement, and the data can be collected in time by the multi-parameter data collector 3 for analysis and processing.

The rainfall runoff measurement equipment in this specific embodiment can automatically monitor and record the rainfall flow process of surface slope runoff plots, and is mainly used in monitoring and recording specific small watershed yield, water flow sediment concentration, river basin sediment yield/sediment delivery, and field runoff plots 1. Indoor artificial simulation of the changes of the above-mentioned relevant parameters on the rainfall slope with the amount of rainfall, the duration of rainfall, and the intensity of rainfall.

The specific embodiment has high degree of automation and convenient management. Compared with the existing runoff measurement method, the measurement accuracy is high and the structure is simple.

The above is a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
