Description

Technical Field

[0001] The utility model belongs to the field of hydrological measurement equipment, in particular to a river section measurement device. Background Art

[0002] River section measurement is an important part of studying the evolution of riverbeds, river regulation and flow measurement. It usually involves measuring and recording parameters such as river width, depth and flow rate. Currently, the commonly used river section measurement methods include suspended depth sounding, manual measurement, bottom sonar measurement and other methods. The test accuracy of suspended depth sounding is not high, and bottom sonar measurement is not convenient to carry out in smaller rivers. When encountering narrow rivers, river section measurement devices are usually set up on both sides of the river, and sonar detection probes are lowered into the river for manual detection. However, the height of most commonly used measurement devices cannot be adjusted. When the heights on both sides of the river are inconsistent, it is difficult to adjust the measurement devices to the same height and keep them level on both sides of the river, resulting in inaccurate measured data and large errors. The measured data is difficult to use and carry out subsequent work. Utility Model Content
