[0002] River flow measurement is an important task for water conservancy departments, and the surface velocity of a river section is usually determined using the buoy flow measurement method. Existing buoy flow measurement methods calculate the surface velocity by placing a marker floating on the water surface and using the time it takes for the buoy to move at a fixed distance.

[0003] Application number "CN202222153603.8" describes a channel surface current velocity and direction observation buoy that supports multiple measurement methods. It includes a float for drifting; an instrument compartment for holding measuring instruments is mounted on the top of the float via an equipment bracket; and a counterweight is fixed to the bottom of the equipment bracket, passing through the float and secured via a detachable connecting pipe. This observation buoy can support multiple different measurement methods to measure channel surface current velocity and direction, and its simple structure and ease of use effectively improve measurement efficiency.

[0004] The above-mentioned equipment also has some problems in use: the buoy does not have anti-collision function, which makes it easy for the device to be damaged internally when it encounters reefs or schools of fish in the water, resulting in significant economic losses. It has poor stability and protection function in use, and its top is not sealed. During long-term use and rain, rainwater can enter the GNSS equipment through the gaps and cause damage. Utility Model Content
