When high-pressure gas in the inner cavity of the floating body structure 3 enters the hollow circular tube support 9, the high-pressure gas drives the piston 10 to move up and down along the tube wall of the inner cavity of the hollow circular tube support 9, the piston 10 drives the crankshaft 12 to do circular motion through the connecting rod 11, the crankshaft 12 drives the blade rotor 14 to do circular motion together with the crankshaft, and then the blades are driven to generate reverse airflow through rotation, so that the effect of wind blocking is achieved.
