Abstract
The self-adaptive ship collision preventing device for the water level of the offshore wind turbine with the single pile foundation mainly comprises an outer-layer thin-wall steel plate structure, a soft rubber spacer structure and a self-weight balance floating body structure. The ship collision preventing device is a gravity and buoyancy self-balancing combined structure and can generate self-adaptive adjustment vertical motion along the single-pile foundation of the wind turbine along with the change of water level. The beneficial effects are that: the outer layer thin-wall steel plate structure can dissipate the collision energy of the ship by utilizing the plastic deformation of the structure; the soft rubber spacer layer structure can effectively reduce the ship collision force transmitted to the tower structure; the arrangement height range of the ship collision preventing device in the area with large tidal level change can be effectively saved by utilizing the water level self-adaptive design scheme of the self-weight balance floating body structure; the device has reasonable structural design and convenient construction, does not influence the structural design of the original wind turbine, and is suitable for the ship collision prevention design of the single-pile offshore wind turbine foundation structure which is built and planned to be newly built.
