Problems solved by technology

Due to the harsh environment of high winds and large waves at sea, the foundation of the floating wind turbine will sway and vibrate due to the impact of wind load and wave load, which will easily damage the foundation of the floating wind turbine; at the same time, the swing vibration of the foundation of the floating wind turbine will be transmitted to the offshore wind turbine. , it is also easy to cause greater damage to offshore wind turbines

Abstract

The invention provides an offshore floating wind turbine foundation and relates to offshore wind power generation technology so as to effectively reduce swing vibration of the floating wind turbine foundation caused by wind loads and wave loads. The offshore floating wind turbine foundation comprises buoyancy tanks, an upright column and supporting frames used for connecting the buoyancy tanks and the upright column and further comprises damping devices, wherein the damping devices are arranged inside the buoyancy tanks, swing along with the buoyancy tanks and absorb the swing energy of the buoyancy tanks. The offshore floating wind turbine foundation is mainly applied to supporting of a floating type offshore wind power generation unit.

Description

technical field [0001] The invention relates to offshore wind power generation technology, in particular to offshore floating wind turbine foundations. Background technique [0002] In the deep sea area far away from the mainland, there are many high-quality wind resources that can be developed and utilized, and the market prospect is broad. When developing wind resources in these deep sea areas, if the current practice generally adopted by offshore wind turbines in shallow sea areas is followed, it is necessary to use various penetrating pile structures fixed on the seabed to fix the foundation of offshore wind turbines. , the basic cost of fixed wind turbines for offshore wind turbines has risen sharply, so the construction cost of fixed offshore wind turbines is higher than that of floating offshore wind turbines. [0003] Therefore, in order to enable the construction of offshore wind turbines to develop in deep sea areas, it is necessary to develop economical and pract...
