Problems solved by technology

However, the complex marine environment will have an adverse effect on the stability of offshore wind power pile foundations, which in turn will cause huge damage to offshore wind turbines
Especially the most widely used monopile foundation is extremely vulnerable to water flow and wave erosion, and the stability of wind turbines is seriously threatened
[0003] The currently commonly used riprap protection is prone to secondary erosion, and the closer to the pile diameter, the deeper the erosion

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] Such as Figure 1 to Figure 2 As shown, a honeycomb anti-scour and sedimentation promoting structure for offshore wind power monopile foundation is composed of a honeycomb device 1 and an anchoring system 2 . The honeycomb device is formed by hot pressing of polymer materials, and the honeycomb cells are provided with through holes 11, and the adjacent honeycomb cells are closely connected by ultrasonic welding seams 12 to form a whole. The honeycomb device forms a flexible network structure through the tension of the anchor system 2 and is fixed on the seabed surface near the offshore wind power monopile foundation. The coverage area of ​​the honeycomb installation is slight...

Abstract

The invention discloses a honeycomb type scour prevention and siltation promotion structure for an offshore wind power single pile foundation. The honeycomb type scour prevention and siltation promotion structure comprises a honeycomb device and an anchoring system, the honeycomb device is of a flexible structure formed by welding a plurality of honeycomb lattice chambers through ultrasonic waves, and holes are formed in the side face of each honeycomb lattice chamber. During use, pulling force is applied to the honeycomb device through the anchoring system, so that the honeycomb device is unfolded around the offshore wind power single pile foundation to be in a grid state.

Description

technical field [0001] The invention relates to the technical field of offshore wind power engineering, in particular to a honeycomb anti-scour and silt-promoting structure used for offshore wind power single pile foundations. Background technique [0002] In recent years, offshore wind power has become a research hotspot in the direction of clean energy development in various countries. my country has a long coastline and numerous islands. my country has also included offshore wind power as an important part of strategic emerging industries. However, the complex marine environment will have an adverse effect on the stability of offshore wind power pile foundations, which in turn will cause huge damage to offshore wind turbines. Especially the most widely used monopile foundation is extremely vulnerable to water flow and wave erosion, and the stability of wind turbines is seriously threatened. [0003] The currently commonly used riprap protection is prone to secondary eros...
