The reel 72 drives the lifting rope 73 to rotate in the opposite direction to unwind the lifting rope 73 wound thereon, and the lifting rope 73 drives the lifting block 74 to move away from the driving motor 71, that is, the lifting block 74 moves away from the top of the offshore integrated platform 100. Under the action of the four lifting blocks 74, the aquaculture cage 50 moves toward the bottom of the offshore integrated platform 100, thereby achieving the purpose of sinking the aquaculture cage 50.

[0074] In some embodiments of the present disclosure, the top of the aquaculture cage 50 is connected to four lifting blocks 74 through four cables 76, and the four cables 76 are respectively connected to the four corners of the top of the aquaculture cage 50 to ensure that the aquaculture cage 50 is evenly stressed.

[0077] In some embodiments of the present disclosure, the vertical wind turbine group 30 includes: a plurality of vertical wind turbines 31, and the rotation axis of each vertical wind turbine 31 is parallel to the height direction of the offshore integrated platform 100. The plurality of vertical wind turbines 31 are arranged in an isosceles triangle array, wherein the center line L3 of the isosceles triangle array is perpendicular to the main wind direction of the target sea area, so as to constrain the flow field divergence behavior of the middle area between two adjacent vertical wind turbines 31 on the side of the isosceles triangle, increase the flow field velocity in the middle area between two adjacent vertical wind turbines 31, form a synergistic effect, and improve the power generation efficiency of the vertical wind turbine group 30.

The multiple vertical wind turbines 31 in this embodiment are of the same size and model.

[0079] In this embodiment, due to the limited space of the outer floating deck 17, on the basis of ensuring the power generation efficiency of the vertical wind turbine group 20, the number of vertical wind turbines 31 is set to three, and the three vertical wind turbines 31 are arranged in an isosceles triangle, and the base midline L3 of the isosceles triangle is consistent with the main wind direction of the target sea area. Specifically, in the isosceles triangle composed of three vertical wind turbines 31, the base is L1, the waist is L2, and the base midline is L3, wherein the length direction of the base midline L3 is parallel to the main wind direction of the target sea area, that is, the length direction of the base L1 is perpendicular to the main wind direction of the target sea area. And the two vertical wind turbines 31 located on the base L1 are in the upwind direction, and the remaining vertical wind turbine 31 is located on the base midline L3, which is in the downwind direction.

[0080] When the main wind direction of the target sea area is parallel to the base midline L3 of the isosceles triangle formed by the three vertical wind turbines 31, the flow field divergence behavior in the middle area between the two vertical wind turbines 31 on the base L1 is constrained, and the flow field velocity in the middle area increases, forming a synergistic effect, thereby improving the overall power generation efficiency of the vertical wind turbine group 20.

[0081] In order to make full use of the synergistic effect between the two vertical wind turbines 31 on the base L1 of the isosceles triangle, the directions of the two vertical wind turbines 31 on the base L1 are set to be opposite, that is, one of the vertical wind turbines 31 rotates clockwise and the other vertical wind turbine 31 rotates counterclockwise, thereby achieving the purpose of further improving the power generation efficiency of the vertical wind turbine set 20.

[0082] In some embodiments of the present disclosure, the distance between the two vertical wind turbines 31 constituting the base L1 of the isosceles triangle is greater than the sum of the radii of the two vertical wind turbines 31. Since the three vertical wind turbines 31 of the isosceles triangle in this embodiment have the same size, the base L1 of the isosceles triangle is greater than 2R. Specifically, the size range of the base L1 of the isosceles triangle is 2.5 to 3.5 times the radius of the vertical wind turbine 31, that is, the size range of L1 is 2.5R to 3.5R, so as to maximize the synergy between the two vertical wind turbines 31 on the base L1.

[0083] In some embodiments of the present disclosure, the length of the base midline L3 of the isosceles triangle is greater than the sum of the radii of the two vertical wind turbines 31. Specifically, the length of the base midline L3 of the isosceles triangle ranges from 2.4 to 6 times the radius of the vertical wind turbine 31, that is, the size of the base midline L3 of the isosceles triangle ranges from 2.4R to 6R, so as to maximize the synergy between the two vertical wind turbines 31 on the base L1 and the remaining one vertical wind turbine 31.

[0084] It should be noted that the distance between two vertical wind turbines refers to the distance between the rotation axes of the two vertical wind turbines.

[0085] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
