Problems solved by technology

Due to the large length of offshore wind power single piles, they are easily affected by extreme sea conditions and erosion. The marine environment where offshore wind turbines are located is complex. The scour pit is formed by local scouring, and the existence of the scour pit weakens the pile-soil effect on the periphery of the single pile foundation, which is detrimental to the stability of the single pile foundation
[0003] Existing engineering technical solutions are difficult to solve this problem, especially not sustainable, which makes the basic operation and maintenance of wind power difficult and risky

Abstract

The ecological protection offshore wind power system comprises a plurality of wind turbine generators used for wind power generation, a plurality of shellfish culture towers are arranged on the upstream portions of the wind turbine generators, and a plurality of seaweed culture devices are arranged on the upstream portions of the shellfish culture towers; the shellfish culture tower and the seaweed culture device are both of a floating structure. Foundation protection of an offshore wind power plant area is achieved through a marine ranch, and meanwhile the balance of income and expenditure is achieved through a mixed breeding mode so that sustainability can be achieved; the invention innovatively provides a novel shellfish culture mode which is combined with a raft type annular seaweed culture mode, so that the space can be developed and utilized to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and in particular relates to a technology for ecological protection of wind power foundation based on offshore pastures. Background technique [0002] Offshore wind power generation has become one of the effective and practical new renewable energy sources today. The monopile foundation is widely used due to its simple structure, small footprint and high bearing capacity. The proportion of single pile foundations to the total amount of offshore wind power is as high as 60%. above. However, the single pile foundation faces a very important problem in some areas, that is, the scour problem of the pile foundation. Due to the large length of offshore wind power single piles, they are easily affected by extreme sea conditions and erosion. The marine environment where offshore wind turbines are located is complex. Under local scouring, scour pits are formed, and the existence of scour pit...
