Description
Technical Field
The invention relates to the field of marine aquaculture, in particular to a platform integrating a self-submerged aquaculture net cage and a floating wind turbine generator.
Background
The national demand for clean energy will increase greatly, and the continuous compression of the arrangement space of offshore wind farms will make the offshore wind farms extend to the deep and distant sea to become a trend.
The offshore fishery culture causes serious pollution in China along the coast for many years, and the problem of reducing the ocean pollution caused by the offshore fishery culture is raised to the national level. The proposal of a plurality of opinions about accelerating the green development of aquaculture industry which is jointly issued by ten committees in rural areas of agriculture is explicitly provided: support the development of deep-sea green culture and encourage the construction of large-scale intelligent deep-sea culture fishery; the research and development and the popularization and the application of large-scale cultivation equipment which enters the sea deeply are encouraged. The fishery breeding will move to deep open sea 15 sea away from the bank;
if the offshore wind turbine and the marine culture are independently arranged, the offshore wind turbine and the marine culture occupy limited sea areas respectively, conflicts between the offshore wind turbine and the marine culture in the use of the sea areas can be caused, and the waste of the use of marine resources can be caused.
The ocean farming needs an effective water body, namely an underwater part, which can be provided by the equipment, and the offshore wind power and offshore wind power generation operation needs an overwater space. Although the two devices are in the same place in the use of the operation sea area, the two devices are relatively independent in the operation mode or space, and if one device can be developed to combine the functions of the two devices, the manufacturing materials of the two devices can be greatly reduced, and the construction cost of the two devices can be reduced.
Therefore, the offshore wind power platform and the aquaculture net cage equipment which can meet the requirements of offshore wind power generation and offshore aquaculture simultaneously are necessary for comprehensively developing and utilizing ocean resources, reducing the comprehensive cost of the equipment and improving the operation efficiency.
The netting of the conventional floating aquaculture net cage platform is directly installed on a floating hull structure internationally, and under severe sea conditions such as typhoon, the floating aquaculture net cage platform has very good sea mobility due to the platform, and the influence of large sea waves on the floating aquaculture net cage platform is very small, but the influence of large waves on aquaculture water in the aquaculture net cage can be reduced due to the condition, or the water in the aquaculture net cage has large fluctuation, and the fluctuation is very unfavorable for marine aquaculture, even death of aquaculture fishes can be caused.
In addition, when a red tide disaster occurs in the aquaculture sea area, algae on the sea surface can occupy the water body in the conventional aquaculture net cage, so that the water body in the aquaculture net cage is reduced, the oxygen content in the water body is reduced, and the cultured fishes in the aquaculture net cage die.

The marine wind power and ocean farming conflict between the offshore wind power and the ocean farming caused by the fact that the offshore wind power and the ocean farming occupy limited sea areas respectively due to the fact that the offshore wind power and the ocean farming are independently arranged and waste in ocean resource use is avoided. The whole platform is required to descend when sea waves come in the traditional structure, but a fan cannot descend, so that the technical difficulty is high. The invention only enables the net cage to descend, and the floating structure can ensure that the fan is above the sea surface, thereby solving the technical problem.
The self-submerging aquaculture net cage is arranged on a floating hull structure frame of a floating generator set platform, and can submerge to an underwater position with the minimum influence of wind waves under the condition of typhoon or severe sea conditions, so that the large wave load generated by the wind waves on the aquaculture net cage is reduced, the aquaculture water in the aquaculture net cage is always complete, and the problem that the fish die due to the fact that the aquaculture water in the aquaculture net cage is reduced due to the waves is avoided. When a red tide disaster occurs at sea, the aquaculture net cage can automatically submerge to a position where the red tide affects the aquaculture net cage to the minimum, the oxygen content of the aquaculture water body and the aquaculture water body of the aquaculture net cage is increased, and the living environment of fish in the aquaculture net cage is improved.
