1. An anti-rolling damping device for floating wind turbines, comprising a support plate (1) and buoys (3) arranged above the support plate (1), where the buoys (3) are movably connected with a fixed frame (2) for fixing a wind turbine, and a bottom of the fixed frame (2) is fixedly arranged on the support plate (1); lower ends of the buoys (3) are connected with an upper surface of the support plate (1) through a damping assembly, and the damping assembly includes a piston cylinder (4) fixedly arranged on the support plate (1), a piston plate (8) is slidably arranged in the piston cylinder (4), a piston rod (9) is arranged at one end of the piston plate (8) far from the support plate (1), and the piston rod (9) extends out of the piston cylinder (4), and is fixedly connected with the buoys (3), and a plurality of first through holes (10) are arranged on a side wall of the piston cylinder (4) near a lower part; the buoys (3) sink with waves, and the piston plate (8) slides downward in the piston cylinder (4), so that the water in the piston cylinder (4) is discharged through the plurality of first through holes (10), and resistance of the piston plate (8) sliding downward is increased.
