FLOATING SUPPORT STRUCTURE FOR AN OFFSHORE WIND TURBINE

摘要

PURPOSE: A floating foundation for a wind power generator is provided to prevent the generation of excessive tensile force by adjusting the height of a buoyancy member according to seawater level change. CONSTITUTION: A floating foundation for a wind power generator comprises a columnar buoyancy member(10), a platform(20), a ballast(30), a flange(40), a mooring wire(50), an elevating device(600) and a balancing buoyancy member. One part of the columnar buoyancy member is submerged in sea surface. The platform is installed on the columnar buoyancy member in order to support a wind power generator. The ballast is arranged on the lower part of the columnar buoyancy member in order to control the draft of the columnar buoyancy member. The flange is installed in the circumference of the columnar buoyancy member. The elevating device moves up and down between the platform and the flange according to the outer circumference of the columnar buoyancy member.
