Embodiment Construction

[0039] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0040] The invention provides a floating wind power generation platform. Among them, the power of a single fan unit is above 3MW. The floating wind power generation platform has excellent motion performance, is friendly in construction and relatively economical in cost. The floating wind power platform is suitable for sea areas with a water depth of more than 30m, especially for medium water depths of 30m to 50m, and has high adaptability in both mild and harsh sea conditions. Its working sea areas can be, for example, the South my country Sea and the Ea...

Abstract

The invention provides a floating type wind power generation platform. The floating type wind power generation platform comprises a floating type foundation and a fan unit. The floating foundation comprises three buoyancy units, three truss units and a fan base arranged on one or two of the buoyancy units. Each buoyancy unit comprises a stand column and a swash deep cabin fixed to the bottom of the stand column. Ballast tanks are arranged in the stand column and the swash deep tank; the section size of the top of the stand column is larger than that of the bottom of the stand column, and any first position and any second position located above the first position in the height direction of the stand column meet the conditions that the section size of the stand column at the second positionis larger than or equal to that of the first position; the swash deep cabin is used as a vertical damping structure; the section size of the swash deep cabin is larger than that of the stand column. The draught fan unit is installed on the draught fan base, and the height of the swash deep cabin of the buoyancy unit where the draught fan unit is located is larger than that of the swash deep cabinof the buoyancy unit where the draught fan unit is not arranged. The wind power generation device has good movement performance, and the power generation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation equipment, in particular to a floating wind power generation platform. Background technique [0002] At present, offshore wind power development is mainly concentrated in shallow water areas, so wind power platforms mainly use fixed foundations such as single piles or jackets. With the gradual reduction of offshore resources, the development of offshore wind power resources is gradually moving towards deep water. As the water depth increases, the construction and installation costs of traditional fixed foundations will increase significantly, so it is suitable for floating foundations with greater water depths It will become the main basic form of future offshore wind power development. [0003] Although a variety of floating wind power foundations have been developed, these floating foundations are still in the conceptual stage, or cannot be applied to medium water depths ...
