Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings.

[0026] See figure 1 To Figure 5, the tendons for the tension leg floating platform of the present invention, the upper end of the floating platform 10 horizontally and evenly lead out four balance legs 11, the outer end of each balance leg 11 and the seabed foundation pile 20 Connect a tendon between.

[0027] The tendon of the present invention includes a main anchor chain 30, multiple auxiliary anchor chains 50 and an anchor chain adjustment mechanism; among them:

[0028] The main anchor chain 30 is formed by connecting a plurality of geared ordinary main anchor chain rings; the auxiliary anchor chain 50 is all formed by connecting a plurality of geared ordinary auxiliary anchor chain rings;

[0029] The lower end of the main anchor chain 30 is connected to the subsea foundation pile 20, and the upper end of the main anchor chain 30 is fixed at the center of the bottom surface of a tran...

Abstract

The invention discloses a tendon used for a tension leg floating type wind power platform. The tendon comprises a main anchor chain, multiple auxiliary anchor chains and an anchor chain adjustment mechanism. The lower end of the main anchor chain is connected to a seabed foundation pile, and the upper end of the main anchor chain is fixed to the center of the bottom face of a transfer platform. The lower ends of the multiple auxiliary anchor chains are evenly distributed and fixed to the top face of the transfer platform, and the upper ends of the multiple auxiliary anchor chains penetrate into penetrating holes formed in the outer end of the same balancing leg. The anchor chain adjustment mechanism comprises an anchor chain rough adjustment mechanism and anchor chain fine adjustment mechanisms. The smallest adjustment travel of the anchor chain rough adjustment mechanism each time is the length of two auxiliary anchor chain rings. Each anchor chain fine adjustment mechanism corresponds to one auxiliary anchor chain to be installed at the outer end of the balancing leg, clamps the corresponding auxiliary anchor chain penetrating through the corresponding penetrating hole of the balancing leg and adjusts the length of the auxiliary anchor chain. The adjustment travel of each anchor chain fine adjustment mechanism each time is the length of 0 to 2 auxiliary anchor chain rings. The problem that a tendon of a tension leg floating type platform is uneasy to replace is solved.

Description

Technical field [0001] The invention relates to a tendon used for a tension leg floating wind power platform. Background technique [0002] At present, offshore wind farms that have been built in China use offshore wind turbines with fixed offshore foundations. With the development of offshore wind farms, the offshore distance and water depth of wind farms continue to increase, and various traditional fixed foundations have been unable to meet the requirements of deep-sea wind energy development. The construction of wind farms will gradually develop into deeper waters. If a fixed foundation is used in offshore wind farms in far-reaching waters, its own weight and construction cost will increase significantly with the depth of the water, so it is not suitable for far-reaching sea environments. Floating wind turbines use floating foundations and mooring systems to adapt to larger water depths. Compared with fixed offshore wind turbines, the manufacturing and installation costs are...
