Floating type wind power foundation with steel-concrete mixed structure

Abstract

The invention discloses a steel-concrete mixed structure floating type wind power foundation, and relates to the technical field of offshore wind power generation. The system comprises a buoy, a transition section, a transverse support steel pipe, an inclined support steel pipe, a heaving plate and a horizontal coupling beam. The buoys are made of concrete materials, prestressed tendons are arranged in the radial directions of the buoys, and upper joints of the buoys are reinforced through inner and outer double-layer steel pipes. The upper part of the transition section is connected with the bottom of the tower drum through a flange; the lower part of the transition section is welded with the steel pipe in the buoy; the transverse supporting steel pipe is used for being connected with the buoy and penetrating the transverse supporting steel pipe into the buoy. The inclined strut steel pipe is used for connecting the buoy and the horizontal coupling beam, and the two ends of the inclined strut penetrate into the buoy and the horizontal coupling beam; the heaving plate is a concrete plate at the bottom of the buoy; and the horizontal coupling beam is used for connecting a heaving plate below the buoy. The system gives full play to the advantages of steel and concrete, is reasonable in stress form, reliable in connection and low in manufacturing cost, and has wide engineering application prospects.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation, in particular to a novel floating foundation for offshore wind turbines suitable for deep-sea areas. Background technique [0002] As a renewable energy, wind energy has many advantages such as abundant storage, clean and pollution-free, and widely distributed. It will play an important role in improving the energy structure, maintaining a green ecological environment, and reducing the greenhouse effect in the future. In recent years, my country's wind power technology has also made great progress. The whole wind turbine has achieved a leap-forward development from 100kW to MW, and has initially mastered the integration technology of 5MW and 6MW. With the gradual saturation of the development of wind power resources in intertidal and offshore areas and the gradual increase in energy demand, it is an inevitable trend for offshore wind power generation to move from intertidal...

Problems solved by technology

[0005] In addition, due to the large fluctuations in the price of steel structure materials and the high unit price, the use of pure steel structure to design and manufacture the foundation of floating wind turbines will have a large difference in cost due to the different production capabilities of each region.
