A cooling system for a shafting and a control method therefor, and a wind turbine are provided. The cooling system includes a cold air supply unit and a rotating-shaft air blow box. The rotating-shaft air blow box is mounted on an inner surface of the stationary shaft and in the shape of a circular ring-shaped box, multiple first air blow openings are uniformly distributed in a surface, facing the rotating shaft, of the rotating-shaft air blow box in a circumferential direction, to blow cold air from the cold air supply unit to the rotating shaft. Each first air blow opening is in the shape of a slit to form a jet.

A movement inhibiting apparatus for a floating offshore wind turbine and a floating base with the apparatus. The movement inhibiting apparatus for the floating offshore wind turbine comprises at least one layer of an annular shake-reducing panel placed horizontally and surrounding the floating base. A plurality of shake-reducing fins is further arranged on the shake-reducing panel. The plurality of shake-reducing fins comprises a first set of shake-reducing fins arranged on one side of the shake-reducing panel and the shake-reducing fins of the first set are spaced apart vertically around the floating base. The movement inhibiting apparatus for the floating offshore wind turbine can effectively inhibit the movement of the floating wind turbine and is of low cost.
