Floating foundation of offshore wind-driven generator

Abstract

The invention discloses a floating foundation of an offshore wind-driven generator, comprising at least one floating foundation unit; the floating foundation unit comprises a tower column, a wind-driven generator, a plurality of float bowls, a connecting rod, a square support, a first supporting rod and a second supporting rod; the wind-driven generator is arranged at the upper end of the tower column; the plurality of float bowls are uniformly distributed at the periphery of the tower column, the lower ends of the adjacent float bowls are fixedly connected through the square support, and the upper ends of the adjacent float bowls are fixedly connected through the connecting rod; the upper ends of the float bowls are fixedly connected with the middle part of the tower column through the first supporting rod, and the square support fixed at the lower ends of the float bowls is fixedly connected with the lower end of the tower column through the second supporting rod; and the square support is located below the surface of seawater, and the lower ends of the float blows are fixedly connected with the seabed. The floating foundation disclosed by the invention is favorable in stability and capable of adjusting the position of the center of the gravity and the resonant frequency of the wind-driven generator and reducing the unbalance degree of bulk movement of the floating foundation in waves. Changed power combination is realized through a plurality of floating foundations so that different power utilization requirements are met.

Description

technical field [0001] The invention relates to offshore wind power generation equipment, in particular to a floating foundation for an offshore wind power generator. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Currently, most wind power projects are on land. With the development of wind power technology, offshore wind power has gradually become a new field of wind power development. Because offshore wind resources are abundant and will not be restricted by land use. Because the wind resources at sea are much better than those on land, and the wind resources in far sea areas are better than those in shallow sea areas in the coastal zone, it is an inevitable direction for wind power to go to the far sea. The current offshore wind power projects are mostly located in offshore areas, using fixed foundations. Floating foundations are an inevitable choice for the development ...

Problems solved by technology

However, the stability of the single floating foundation of this patent is poor, and each unit is connected by elastic thin cables, which is prone to collisions, resulting in easy damage to the floating foundation
