Semi-submersible floating foundation for offshore wind power generation and cage culture

Abstract

The invention discloses a semi-submersible type floating foundation for offshore wind power generation and cage culture. The semi-submersible type floating foundation comprises stand column units, transverse supporting assemblies, a truss structure and a culture cage, wherein the stand column unit comprises a heaving plate and a stand column, and the stand column is arranged on the heaving plate and filled with concrete; the transverse supporting assembly comprises a first transverse supporting rod and a second transverse supporting rod, the first transverse supporting rod is connected with the two adjacent heaving plates, the second transverse supporting rod is connected with the two adjacent stand columns, and the first transverse supporting rod and the second transverse supporting rod are both filled with concrete; and the truss structure is connected between the first transverse supporting rod and the second transverse supporting rod, a culture space is defined by the stand column units, the transverse supporting assemblies and the truss structure, and the culture cage is installed in the culture space. According to the semi-submersible floating foundation for offshore wind power generation and cage culture, the steel-concrete structure is used as fixed ballast, so that the draft of the floating foundation is increased, the steel consumption of the overall structure is reduced, meanwhile, the rigidity and strength of the local structure are enhanced, the material use cost is reduced, and the income is increased.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a semi-submersible floating foundation for offshore wind power generation and cage culture. Background technique [0002] With the gradual saturation of wind resource exploitation in inland and offshore areas and the further increase in national energy demand, coupled with the high construction costs of offshore and deep-sea wind power and the development of composite industries, the offshore wind power industry has begun to try to integrate deep-sea aquaculture. and other industries to carry out research on composite industries, from the intertidal offshore area to the deep sea area. The shallow sea is closer to the coast, which is likely to have an impact on offshore fish farming and channel planning. Compared with shallow sea wind power, deep sea wind power has abundant wind resource reserves and stable wind resources. It has the advantages of high wind speed, lo...

Problems solved by technology

[0004] At present, the main form of the semi-submersible is a column-stable structure, and the main bodies are connected by cross-bracing trusses. Usually, the cross-bracing trusses are composed of many struts, which not only increases the complexity of the entire floating foundation structure, but also Increased construction and post-maintenance costs, many strut structures make the structure fatigue problem prominent, at the same time, in order to ensure the stability of the entire floating wind power structure, the floating foundation needs to reach a certain draft, and the all-steel floating foundation requires greater external ballast
