The netting component includes a number of nettings connected end to end. Among them, two adjacent nettings are near-monopile nettings, and the other nettings are far-monopile nettings. The two near-monopile nettings are connected by the monopile foundation. The near-monopile netting is connected to the adjacent far-monopile netting and the two adjacent far-monopile nettings are connected by auxiliary piles. Grooves are arranged vertically on the monopile foundation and / or the auxiliary piles. A number of connecting pieces are arranged at upper and lower intervals at both ends of the netting, and the connecting pieces are snapped into the grooves of the corresponding monopile foundation or auxiliary pile.

[0007] Further, the groove is an arc-shaped clamping groove, and its arc is greater than 180°. The connecting piece is a sphere and is press-fitted into the groove.

[0008] Further, an operation and maintenance passage is arranged at the upper end of the netting component.

[0009] Further, one end of the operation and maintenance passage is connected to the monopile foundation, and the other end is supported on the auxiliary pile.

[0010] Further, two grooves are arranged on the monopile foundation and are respectively connected to the connecting pieces on two adjacent nettings.

[0011] Furthermore, two grooves are provided on the auxiliary pile and are respectively connected to the connecting members on two adjacent net cages.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1) The present utility model combines the single-pile foundation of offshore wind power with the offshore aquaculture cage, and proposes a structure of an offshore wind power single-pile foundation aquaculture cage based on an auxiliary pile, realizing the integrated development of offshore wind power and the offshore ranch structure, which can give play to their respective advantages, realize the sharing of resources such as electricity and operation and maintenance, and create additional economic value;

[0014] 2) The cage structure of the present utility model is simple, fully utilizes the single-pile foundation and the auxiliary pile to provide support for the aquaculture cage, the cost of the cage structure is low, and the construction is convenient;

[0015] 3) In view of the fixing requirement of the net cage on the pile foundation, the present utility model proposes a net cage fixing method based on grooves, and this fixing method is convenient for construction and easier to disassemble;

[0016] 4) The present utility model forms an integral body of the single-pile foundation and the cage. The existence of the single-pile foundation can reduce the oncoming flow and the downstream flow velocity, playing a shielding effect, which is helpful for the growth of fry in the cage and can improve the flow velocity adaptability of the cage; at the same time, the existence of the net cage can also reduce the flow velocity around the single-pile foundation to a certain extent, thereby alleviating the pile foundation scouring phenomenon and playing a role in preventing scouring.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 and Figure 2, An offshore wind power monopile foundation aquaculture cage structure based on auxiliary piles, comprising a netting component, a monopile foundation 1 and a number of auxiliary piles 2. The netting component includes a number of nets 3 connected end to end. Among them, two adjacent nets 3 are near-monopile nets, and the other nets are far-monopile nets. The two near-monopile nets are connected by the monopile foundation 1. The near-monopile net is connected to the adjacent far-monopile net and the two adjacent far-monopile nets are connected by the auxiliary piles 2. Grooves 5 are arranged vertically on the monopile foundation 1 and the auxiliary piles 2. A number of connecting pieces 6 are arranged at upper and lower intervals at both ends of the net 3, and the connecting pieces 6 are snapped into the grooves 5 of the corresponding monopile foundation 1 or auxiliary pile 2.

[0022] Continue to refer to Figure 1 , In an embodiment of the present invention, an operation and maintenance passage 4 is arranged at the upper end of the netting component. One end of the operation and maintenance passage 4 is connected to the monopile foundation 1, and the other end is supported on the auxiliary pile 2. The operation and maintenance passage 4 enables personnel to board the wind turbine.

[0023] Continue to refer to Figure 2 , In an embodiment of the present invention, the groove 5 is an arc-shaped card slot, the arc of which is greater than 180°. The connecting piece 6 is a sphere, made of rubber or other elastic materials. The connecting piece 6 is press-fitted into the groove 5.
