Abstract

The invention discloses a truss inhaul cable type floating offshore wind turbine generator structure. The structure comprises ballast tanks arranged in a triangular shape, mooring systems are fixedlyconnected to all corners of the ballast tanks, truss type structures are fixedly connected to the upper portions of the ballast tanks through first stay cables, and the truss type structures are connected through transverse inhaul cables; and a mounting platform is fixedly connected to a certain elevation above the truss type structures through a plurality of inclined struts, the upper surface ofthe mounting platform is fixedly connected with the bottom end of a fan tower, and a fan is fixedly connected to the top end of the fan tower. By means of the special truss structure types, the wave load borne by the structure near a water plane is reduced, the requirement of the structure for restoring force is lowered, then the appearance size of the structure is reduced, and the steel consumption is reduced; and by means of the special inhaul cable design, the steel consumption of the fan tower at the upper portion is effectively reduced, the design of lower floating body connecting transverse supports and connecting inclined supports is effectively omitted, the dead weight is reduced, and the construction cost is saved.

Description

Technical field [0001] The present invention relates to the technical field of offshore wind power development equipment, and more particularly to a trussed zostroof floating sea wind power unit structure. Background technique [0002] my country is in a crucial stage of the transition energy, wind energy as a renewable clean energy technology matures, costs continue to decline, it plays a pivotal role in my country's new energy development. Compared with the on-site wind power, sea wind power generation has a unique advantage. The sea has a rich resources and wind speed and wind direction; the sea wind farm has no land resources; the single-machine capacity is large, suitable for large-scale development. At present, the development of close-sea fixed wind power has basically realized industrialization, and some early establishment of near-seafood electric fields are in the middle and later development stage. However, for floating wind power development facing the water depth of ...
