However, with the continuous promotion of offshore marine development, the trend of the fusion and coordination development of the marine ranch and other marine modes is more and more obvious under the conditions that various marine modes occupy the sea space, the marine contradiction is more and more prominent, and the ecological protection is more and more strict. In recent years, offshore wind power in China is developed rapidly, the development technology is basically mature, equipment is upgraded continuously, and the offshore wind power is developed in a large scale. The offshore wind power suction cylinder foundation can effectively exert the advantages of a pile foundation and a traditional cylindrical structure through a connecting structure, and solves the engineering problems of short bedrock buried depth, short construction window period and the like. The suction tube foundation structure is utilized to provide convenient conditions for arrangement of marine ranching facilities, mutual influence between a wind power foundation and cultivation facilities is reduced, layered three-dimensional development of a sea area is achieved, and the suction tube foundation structure is a new challenge for exploring the fusion development of a marine ranching and an offshore wind power station.

SUMMERY OF THE UTILITY MODEL

Based on the technical characteristics: the four offshore wind power suction cylinder foundations are respectively positioned at four corners of the space and are uniformly distributed to form a unit sea area.

Based on the technical characteristics: the shellfish raft frame is rectangular, four mooring lines are uniformly arranged on one side, the mooring lines at the corner points of the rectangle are overlapped, twelve mooring lines are counted, and the offshore wind power suction cylinder foundation is connected with the shellfish raft frame through the twelve mooring lines.

Based on the technical characteristics: one end of each of the three mooring lines is connected to one position, and the mooring lines are tied to the mooring anchors at the tops of the adjacent suction cylinders.

The utility model has the beneficial effects that:

1. the mooring anchor at the top of the suction cylinder can be built in a land area environment, the mooring line can be fixed on the mooring anchor in advance and sinks to the seabed along with the hoisting of the wind-power foundation of the suction cylinder, and the offshore operation time can be effectively shortened while the mooring safety is ensured.

2. The mooring anchor is fixed on the sea bottom through the suction tube, and compared with other offshore wind power foundations (such as single piles, high pile bearing platforms, jackets and the like), the whole cylinder body is firmly fixed on the sea bottom due to the fact that the top cover of the suction tube is in complete contact with the surface of the sea bed, the top cover of the suction tube replaces a foundation main body to be provided with mooring points, the additional load generated on the wind power foundation due to movement of the shellfish algae raft culture equipment can be effectively reduced, meanwhile, the damage to the foundation main body due to mooring pulling can be reduced, and therefore the safe and stable operation of the wind power foundation is guaranteed.

3. The shellfish raft frame is arranged in the middle sea area surrounded by the offshore wind power suction cylinder foundation, so that sea surface area can be saved, and the fusion development of an offshore pasture and an offshore wind power plant is realized.
