Problems solved by technology

[0003] As a special type of platform, the floating wind power platform is fundamentally different from conventional marine structures. Unfavorable factors such as the large weight of the wind turbine itself, the high center of gravity, the wind receiving area and the large wind inclination moment make the overall layout and configuration of the floating wind power platform Design is more technically challenging than traditional floating platforms

Embodiment Construction

[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] figure 1 It is a schematic diagram of a Spar type 5MW offshore floating wind power generation platform provided by an embodiment of the present invention, as figure 1 As shown, the platform includes a 5MW wind turbine 1, a central column 2, a buoyancy chamber 3, a ballast chamber 4, a damping plate 5, and struts.

[0028] Optionally, the struts include main struts 6 and auxiliary struts 7 .

[0029] The 5MW wind turbine 1 is arranged above the platform and connected with the central column 2 .

[0030] The central column 2 and the buoyancy chamber 3 are directly connected to form the main buoyant body of the platform.

[0031] The central column 2 and the buoyancy chamber 3 form the main floating body of the platform to provide a supporting foundation for the 5MW wind turbine 1, providing buoyancy and structural strength.

Abstract

The invention discloses a spar type 5MW marine floating wind power generation platform and relates to the field of wind energy utilization. The spar type 5MW marine floating wind power generation platform comprises a 5MW fan, a central column, a buoyancy tank, a ballast tank, a damping plate and a supporting rod; the 5MW fan is placed above the platform and connected with the central column; the central column is directly connected with the buoyancy tank to form a main floating body of the platform; the central column is arranged above the buoyancy tank; the section dimension of the central column is less than that of the buoyancy tank; the ballast tank is arranged under the buoyancy tank; the buoyancy tank is connected with the ballast tank through the supporting rod; and a damping plateis arranged between the buoyancy tank and the ballast tank. Wind power generation in deep ocean is realized, and the safety and stability of the floating wind power generation platform are improved.

Description

technical field [0001] The invention relates to the field of wind energy utilization, in particular to a Spar-type 5MW offshore floating wind power generation platform. Background technique [0002] At present, although the development and utilization of offshore wind power has a certain scale, it is mainly developed based on offshore fixed wind farms. This kind of wind farm mainly uses single piles or jacket foundations to fix wind turbines on the seabed. However, the application of these two schemes in sea areas with a water depth of more than 50 meters will lead to a sharp increase in engineering difficulty and manufacturing costs. Sea areas with a water depth of more than 50 meters have the characteristics of higher wind speed and better wind quality, higher power generation efficiency, and greater development potential. [0003] As a special type of platform, the floating wind power platform is fundamentally different from conventional marine structures. Unfavorable fa...
