Problems solved by technology

However, the existing offshore wind power pile foundation is unstable, which may easily cause accidents of offshore wind power generators.
Specifically, due to the action of waves and tidal currents, the offshore wind power pile foundation will scour the sediment around the foundation and form scour pits, which will affect the stability of the pile foundation; at the same time, near the seabed surface The water flow mixed with sand will continuously scour the pile foundation, corrode and damage the surface of the pile foundation, and in severe cases, it will cause the collapse of the offshore wind turbine unit
In order to solve the above problems, the existing method is to use the riprap protection method, but the riprap protection is greatly affected by the terrain, the stability of the pile foundation cannot be guaranteed, and the maintenance cost and workload are large

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0027] Such as Figure 1 to Figure 5 As shown, the anti-scouring device for offshore wind power piles in this embodiment includes the anti-scouring cover 2 and the elastic pressing member 3 . Among them, the anti-scour cover 2 is set at the position of the pile foundation 1, forming an anti-scouring space at the position of the pile foundation 1, which can effectively reduce the erosion damage to the pile foundation 1 caused by waves and tidal currents, and avoid the impact of the riprap protection from the terrain Large phenomenon, it can be applied to complex terrain, wide adaptability, easy installation and operation, low maintenance cost; anti-scourh enclosure cover 2 includes a cover plate 21 and an enclosure frame 22, and the enclosure frame 22 is arranged...

Abstract

The invention provides an anti-scouring device for offshore wind power piles. The device comprises an anti-scouring cover for reducing scouring of wave and tidal current to a wind power pile foundation and an elastic pressing part for preventing collapse of the seabed surface. The anti-scouring cover is disposed at the position of the pile foundation and comprises a cover plate and a surrounding frame disposed under the cover plate, wherein the elastic pressing part is disposed between the cover plate and the seabed in a compression mode. The anti-scouring device has the advantages of ensuringthe stability of the pile foundation and being wide in adaptability and convenient to operate and install.

Description

technical field [0001] The invention relates to the field of offshore wind power piles, in particular to an anti-scouring device for offshore wind power piles. Background technique [0002] Offshore wind turbines are a clean and environmentally friendly way of generating electricity, and the offshore wind power pile foundation is the key to supporting the entire offshore wind turbine. However, the existing offshore wind power pile foundation is unstable, which may easily cause accidents of offshore wind power generators. Specifically, due to the action of waves and tidal currents, the offshore wind power pile foundation will scour the sediment around the foundation and form scour pits, which will affect the stability of the pile foundation; at the same time, near the seabed surface The water flow mixed with sand will continuously scour the pile foundation, corrode and damage the surface of the pile foundation, and in severe cases, it will cause the collapse of the offshore ...
