Abstract

The invention discloses an anti-flushing device of an offshore wind power pile foundation. The anti-flushing device comprises an anti-flushing main body and a plurality of flexible elements; the flexible elements comprise fixed ends and energy dissipation ends; the flexible elements are fixed to the anti-flushing main body through the fixed ends; and the anti-flushing main body is fixed to a seabed. Compared with the prior art, according to the anti-flushing device of the offshore wind power pile foundation, through modes such as frictional resistance, impact, vortex, deflecting flow, diffusion and aeration between a water flow and fiber cloth strips, a rapid flow or a main flow is transformed into an evenly-diffused slow flow as soon as possible, and thus the effects of collision mixing and friction shear stress between energy dissipation and diffusion are achieved.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to an anti-scouring device for offshore wind power pile foundations. Background technique [0002] According to the latest data, offshore wind power generation is a clean and environmentally friendly power generation method, and all countries are vigorously promoting it. Wind power generation is second only to hydropower generation and accounts for 16% of the global renewable resource power generation. my country's offshore wind power installed capacity is also growing year by year. In the context of the global focus on developing a low-carbon economy, offshore wind power has the potential to become a game-changing renewable energy power. In densely populated coastal areas, gigawatt-scale offshore wind farms can be quickly established, which also makes offshore wind power one of the most important technologies to reduce carbon emissions in energy production in a cost-effective ma...
