Description

Technical Field

[0001] The utility model relates to the technical field of flow velocity measurement, and more specifically, to a device for measuring the flow velocity of a river water flow. Background Art

[0002] Measuring the flow velocity of river water is an important task in hydrological measurement, and is of great significance to river management, flood prevention and disaster reduction, water resource protection and utilization. Flow meters are commonly used equipment for measuring water flow velocity, including buoy type, electromagnetic type, Doppler type and other types. These instruments can be installed on ships or fixed brackets to obtain flow velocity data by directly measuring the speed of the water flow.

[0003] In the existing measurement method, staff use handheld radio current meters to measure the water flow velocity near the bank of the river. However, this measurement method can only measure the water flow velocity near the bank and cannot measure the water flow velocity at deeper depths, resulting in low accuracy of the measurement results and reduced adaptability and practicality of the measuring device. At the same time, the existing measuring instruments are not easy to install and disassemble with the supporting components, and thus it is not easy to move and maintain the measuring instruments, which reduces the convenience during use.
