[0002] In the development of ocean resources, there is no direct structural connection between offshore aquaculture and offshore wind farms, and both are simply placed in a certain area of the offshore wind farm site directly or indirectly. There is a lack of relevant structural linkage between the two, and each occupies a certain sea area, resulting in great waste.

[0003] The existing offshore aquaculture net cage is customized according to a certain scale, which is not convenient to expand after installation, and lacks a certain adjustability. In addition, in order to improve stability, a corresponding foundation pile needs to be further added, causing resource waste and cost increase.

[0004] The single pile foundation is the most widely used offshore wind turbine foundation at home and abroad. The single pile foundation uses a steel pipe pile with a diameter of about 8-10m. The steel pipe pile is driven into the seabed to a certain depth by a pile hammer to bear the load generated by the work of the wind turbine. According to relevant regulations, the sea area of the offshore wind turbine single pile foundation is calculated according to the circular area with a radius of 50m extending outward from the center point of the tower to the outer edge line point of the wind turbine foundation. There is a lot of unused sea area around the single pile foundation, and the space volume is considerable. If it can be reasonably utilized, it will generate great economic value.

[0005] Therefore, it is necessary to design a fish net cage based on offshore wind turbine single pile foundation. CONTENT OF THE UTILITY MODEL
