Control techniques for controlling a pitch angle of blades of a floating wind turbine during a shutdown operation are provided. A control technique includes obtaining a floater angular displacement of a floating platform coupled with a tower of the floating wind turbine; increasing the pitch angle of the blades at a first pitch adjustment rate from initiation of the shutdown operation until an acceleration of a rotor of the floating wind turbine has peaked; maintaining the pitch angle of the blades substantially constant from when the acceleration of the rotor has peaked until the floater angular displacement changes from positive to negative or has peaked to preserve thrust of the rotor and to dampen a moment of a base of the tower; and increasing the pitch angle of the blades at a second pitch adjustment rate when the floater angular displacement changes from positive to negative or has peaked.

The utility model relates to the technical field of navigation marks, in particular to an anti-drifting navigation mark connecting structure which comprises a floating platform part, the inner wall of the floating platform part is connected with the outer wall of a driving part in a clamped mode, the top end of the driving part is fixedly connected with the bottom of a warning part, and the bottom of the warning part is fixedly connected with the top of the floating platform part. The top of the floating platform piece is fixedly connected with the bottom of the winding piece, sea wind blows windmill pieces to rotate, the windmill pieces drive a generator to rotate through a rotating disc to generate electricity, electricity generated by the generator is stored in a storage battery and supplies power to a warning lamp, the windmill pieces rotate to drive a rotating plate to rotate, the rotating plate drives a rotating rod to rotate, and the rotating rod drives a protective cover to rotate. When the protective cover rotates, the warning lamp can be prevented from being impacted by external force, the service life of the warning lamp is prolonged, the situation that the warning lamp is broken or cannot be normally used is avoided, meanwhile, the warning lamp is driven to rotate so that lamplight can be more striking, and convenience is brought to use of people.
