Problems solved by technology

As far as the existing offshore wind farms in China are concerned, the auxiliary berthing structure of single-pile foundation and multi-pile foundation is not yet mature. The usual practice is that the ladder of the wind turbine foundation is directly connected to the foundation pile legs, and it is easy for the operation and maintenance ship to directly hit it when docking. On the ladder and the foundation pile legs, it is easy to

Embodiment Construction

[0013] refer to Figure 1 to Figure 3 , an offshore wind turbine foundation anti-collision structure, including foundation legs 1, the foundation legs 1 generally have 3-8 pieces, the foundation legs 1 are installed with anti-collision devices, and the anti-collision devices include The upper circular tube ring 4 and the lower circular tube ring 5 of the foundation pile leg 1, a number of vertical circular tubes 6 are arranged between the upper circular tube ring 4 and the lower circular tube ring 5, and the vertical circular tubes 6 are A rubber sleeve 7 is installed, and the rubber sleeve 7 can buffer the collision force. The two ends of the vertical circular pipe 6 are directly welded on the upper circular pipe ring 4 and the lower circular pipe ring 5 .

[0014] Between the upper circular pipe ring 4 and the lower circular pipe ring 5, there are vertical support pipes 8 equal in number to the foundation legs 1, and the two ends of the vertical support pipes 8 are directly ...

Abstract

The invention discloses an offshore wind turbine foundation anti-collision structure which comprises foundation pile legs, wherein anti-collision devices are mounted on the foundation pile legs; the anti-collision devices comprise upper circular tube rings and lower circular tube rings, which are fixed on the foundation pile legs; a plurality of vertical circular tubes are arranged between the upper circular tube rings and the lower circular tube rings; rubber sleeves are mounted on the vertical circular tubes. The foundation pile legs are not collided when operation and maintenance ships berth; because of the anti-collision device, impact force, generated when the operation and maintenance ships berth is reduced; the potential safety hazard to offshore wind plant maintenance personnel during landing on a wind turbine is reduced to the minimum extent, so that the working security is improved; negative influences on the offshore wind turbine foundation, generated when a ship berthing structure is collided by ships is reduced, and thus the security and reliability of the wind turbine foundation within the service life are improved.

Description

technical field [0001] The invention relates to wind power equipment, in particular to a wind turbine foundation auxiliary structure of an offshore wind farm. Background technique [0002] At present, my country's offshore wind power generation is still in its infancy, and most of the foundation and auxiliary structures of offshore wind turbines are blank. As far as the existing offshore wind farms in China are concerned, the auxiliary berthing structure of single-pile foundation and multi-pile foundation is not yet mature. The usual practice is that the ladder of the wind turbine foundation is directly connected to the foundation pile legs, and it is easy for the operation and maintenance ship to directly hit it when docking. On the ladder and the foundation pile legs, it is easy to cause local deformation of the foundation pile legs, which shortens the service life of the wind turbine foundation and increases the maintenance cost in the later period. [0003] In addition,...
