Problems solved by technology

However, deep-sea offshore wind power generally adopts floating offshore wind power foundations. Floating offshore wind power has high technical content and high investment costs, resulting in relatively low benefits. This has caused great pressure on my country's offshore wind power grid parity and sustainable development.

Abstract

The invention discloses a floating type offshore wind power foundation structure with an additional net cage. The structure comprises a floating type foundation mechanism. According to the structure,deep sea floating type offshore wind power and the aquaculture net cage are combined, the contradiction between offshore wind power development and fishery aquaculture is solved, meanwhile, ocean resources can be saved and utilized easily, and the economic benefits of the two industries are improved. A semi-submersible floating type foundation mode is adopted, the system can be suitable for installation of a ten-megawatt offshore wind turbine generator, the investment of the whole system is not sensitive to the water depth, and the system can be suitable for a sea area with the water depth ranging from 80 m to 1500 m. A floating foundation mechanism is adopted at the upper part; the lower part adopts a separated design of a ballast tank mechanism; according to the structure, the motion response of the floating type draught fan under the wave flow effect can be effectively reduced, damage caused by too large stress at the joint is avoided through the flexible connection mode, meanwhile,the ballast box is made of reinforced concrete materials, and the cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of offshore wind power and aquaculture facilities, in particular to a floating offshore wind power foundation structure with combined design of deep-sea floating offshore wind power foundation and aquaculture net cage with additional net cages. Background technique [0002] Offshore wind power, as a renewable energy source, is an important part of my country's energy structure. Now my country's offshore wind power has entered a stage of large-scale development, and there is a trend of increasing single-unit capacity and deeper and deeper development water depth. The trend of offshore wind power The deep sea is inevitable for the development of the industry. And at the national level, it clearly proposed to support the development of offshore wind power in deep seas. The state clearly proposed to "encourage the construction of offshore wind farms in deep seas". Develop customized ocean energy power ge...
