Semi-submersible floating type wind turbine foundation structure

Abstract

The invention provides a semi-submersible floating type wind turbine foundation structure which comprises an offshore wind power generation assembly and a floating assembly. The floating assembly comprises a center buoy and foundation buoys, the floating assembly further comprises anti-wave flat plates arranged on the center buoy and the foundation buoys, and through holes are formed in the anti-wave flat plates. According to the semi-submersible floating type wind turbine foundation structure, the anti-wave flat plates are arranged on the center buoy and the foundation buoys, the anti-wave flat plates can break waves and absorb energy, scouring of sea waves to the floating assembly is weakened, impact energy in the waves is consumed, impact force of the sea waves to a tower column is weakened, and fatigue damage to the tower column is reduced. Motion response of the offshore wind power generation assembly under the coupling action of wind, waves and flow can be greatly reduced, the stability of the offshore wind power generation assembly is enhanced, fatigue damage caused by sea wave scouring to the center buoy and the foundation buoys of the offshore wind power generation assembly is reduced, and the service life of a whole offshore wind turbine is prolonged.

Description

technical field [0001] The invention relates to the technical field of offshore fan protection basic equipment, in particular to a semi-submersible floating fan basic structure. Background technique [0002] As people's awareness of environmental protection continues to increase, more and more green new energy sources are developed and utilized, thereby reducing carbon emissions. The sea is rich in wind energy resources, which is the main direction of new energy development and utilization. At present, offshore wind power development is mainly concentrated in shallow water areas, and wind turbines mostly use fixed foundations. With the deepening of development, offshore wind power development will develop in offshore deep water areas. As the development water depth increases, the fixed wind turbine foundation gradually loses its superiority, and the floating foundation becomes the ideal wind turbine support foundation. [0003] The mooring system of the floating foundatio...
