Offshore wind turbine anti-scouring structure and setting method thereof

Abstract

The invention provides an offshore wind turbine anti-scour structure and a setting method thereof, and the offshore wind turbine anti-scour structure comprises a tire bracket and a tire which are arranged around a pile in a sleeving manner in order to weaken a submerged current, a flat tire which is arranged in order to weaken a horseshoe-shaped vortex, a vertical tire which is embedded at a certain depth, and a conical arc-shaped structure tire which is arranged in order to weaken a trailing vortex, the three structures provide support with one another, so that the pile can be effectively protected. The anti-scouring structure has the advantages of being safe, environmentally friendly, simple in structure, easy to install, convenient to construct, low in construction cost and the like.

Description

technical field [0001] The invention belongs to the technical fields of ocean engineering and offshore wind power, and in particular relates to an anti-scouring structure of an offshore wind turbine and a setting method thereof. Background technique [0002] At present, the world is facing major changes in new energy technologies, and developing clean and low-carbon energy and addressing climate change has become a new trend. Whether it is offshore or onshore wind power, as a clean energy source, more and more attention has been paid by the scientific and commercial circles. For offshore power generation, the pile foundation needs to solve the problem of anti-current, wave erosion, which causes the sand around the pile to be hollowed out, resulting in instability and corrosion of the pile by sea ions. In the early days, concrete or sand and gravel were usually placed in a certain range, but in order to maintain the anti-scouring effect, sand and gravel must be continuously ...

AI Technical Summary

Problems solved by technology

Although the above two anti-scouring technical solutions have all turned waste into treasure and rationally utilized discarded tires, there are common shortcomings in the two. The anti-scouring parts laid flat on the seabed have limited anti-scouring effects, and the surge of ocean currents When encountering a complex flow field, the tire laying method cannot play a good role

[0004] In the publication number CN104213586A, the Chinese patent titled "A Pile Foundation Erosion Protection Measure Method" proposes to reduce the erosion of the pile foundation by the water flow by setting the piles in front of the pile and the retaining ring around the pile group. However, the front row of piles has certain requirements on the seabed environment around the pile foundation, and if discarded tires are used as retainers, the diameter of the pile foundation is also limited to a certain extent. This technical solution cannot be applied to large piles. base

[0005] To sum up, the existing anti-scour protection works for offshore pile foundations rationally utilize waste tires, and at the same time, there are deficiencies in the anti-scour effect and universality.
