Shallow draught floating type wind generating set foundation platform

Abstract

The invention discloses a shallow draught floating type wind generating set foundation platform which is of a triangular barge type and comprises a hull and a mechanical cabin arranged in the hull. The hull is divided into a hull upper part and a hull lower part; the mechanical cabin at the upper part of the hull comprises chain lockers, an electromechanical equipment cabin, an electrical equipment cabin and an empty cabin; the three chain locker bodies are arranged at the three vertex angles of the hull respectively. The mechanical cabin on one side of one chain locker is sequentially provided with an electromechanical equipment cabin, an electrical equipment cabin and an electromechanical equipment cabin; a mechanical cabin on the other side of the chain locker is an electromechanical equipment cabin; the rest cabins are empty cabins; a mechanical cabin in the middle of the upper portion of the hull is a wind power control equipment cabin, and a wind turbine generator installation base is fixed to the upper portion of the wind power control equipment cabin. The foundation platform adopts a triangular barge type as the foundation platform, has the characteristics of simple structure, shallow draft, stable floating, safety in use and the like, and is particularly suitable for being used in an offshore shallow water environment.

Description

technical field [0001] The invention relates to a base platform of a generator set, in particular to a base platform of a shallow-draft floating wind power generator set. Background technique [0002] The existing floating foundations used for marine resources development mainly include four types: column-stabilized semi-submersible foundations, damping pool foundations, single-column foundations, and tension leg foundations. The column-stabilized semi-submersible foundation is composed of multiple stabilizing columns providing buoyancy and diagonal braces between the stabilizing columns. The interior of the stabilizing columns is provided with a ballast tank, and the bottom of the stabilizing columns is provided with a heave structure; Mooring positioning equipment and other equipment. The foundation of the damping pool is a square barge-shaped platform, with a square moon pool in the center, and wind power generators, mooring and positioning equipment and other equipment ...

AI Technical Summary

Problems solved by technology

However, in the existing floating foundations, the column-stabilized semi-submersible foundation has limited buoyancy provided by the column, and the design draft is increased to form sufficient buoyancy to meet the needs of floating foundations and marine resource development equipment, so it is mostly used in deep waters in the offshore ;The damping pool foundation adopts a square hull type, and the square is not a stable shape, resulting in large main scale, large frontal area, and large environmental loads such as wind, wave and current, which exacerbates the difficulty of developing shallow water mooring systems; single column foundation and tension leg The foundations are typical deep-draft floating platforms used in deep water, which are not suitable for shallow waters along the coast of islands, and the structural form is not conducive to the simultaneous arrangement of wind turbines, wave energy generation devices and mariculture facilities on the foundation.

Therefore, the existing floating foundation cannot meet the needs of the development of my country's coastal marine resources.
