Offshore wind turbine foundation structure and lightweight design method

Abstract

The invention discloses an offshore wind turbine foundation structure and a lightweight design method. The offshore wind turbine foundation structure comprises a jacket; the bottom of the jacket is fixed to four piles, the top of the jacket is provided with a transition block, and a wind turbine tower is arranged on the transition block; the jacket comprises four pile legs and a cross structure; and the cross structure is arranged among the pile legs and comprises five layers, including X-shaped structures and K-shaped structures. The offshore wind turbine foundation structure has the advantages that a traditional installation structure of the jacket is changed, a continuum structure is directly optimized by establishing a continuum model, a reasonable truss-type structure with a reasonable force transfer path is obtained, the overall stress is more uniform while the structural weight of the jacket is reduced, and the working safety coefficient is improved.

Description

technical field [0001] The invention relates to the field of wind power generation basic equipment, in particular to an offshore wind turbine basic structure and a lightweight design method. Background technique [0002] With the introduction of green economy and the vigorous development of new offshore energy in recent years, new requirements have been put forward for the design of wind turbine infrastructure: to improve structural performance and reduce manufacturing costs. For the design and manufacture of traditional offshore wind turbine infrastructure, in order to ensure the normal progress of resource mining and the safety of staff, the platform is often designed conservatively, bulky and heavy, and the overall force is uneven; correspondingly, the cost of production and installation is low. high. In the past, the optimization of the platform structure was often based on the original platform, with limited modifications to the size and location of the wind turbine in...

Problems solved by technology

For the design and manufacture of traditional offshore wind turbine infrastructure, in order to ensure the normal progress of resource mining and the safety of staff, the platform is often designed conservatively, bulky and heavy, and the overall force is uneven; correspondingly, the cost of production and installation is low. high

In the past, the optimization of the platform structure was often based on the original platform, with limited modifications to the size and location of the fan base structure, and the optimization effect was not particularly obvious.
