The first cavity 11 is a closed cavity, and the first cavity 11 is used to provide buoyancy for the buoy 1, so that the buoy 1 can float on the water surface. In addition, the buoy 1 also has redundant buoyancy to support the cylindrical member to float on the water surface.

[0041] The air inlet and outlet pipe 13 is arranged at the top of the second cavity 12, and is used to introduce air into the second cavity 12 or exhaust air from the second cavity 12, so as to adjust the air pressure in the second cavity 12 and the size of the buoyancy of the buoy 1.
