Embodiment 1
[0029] Such as figure 1 , figure 2 As shown, this embodiment provides a variable cross-section three-column offshore floating wind power foundation, which mainly includes a bottom structure 1 , a central column 2 and a circumferential column 3 . In this embodiment, the structure provided with three said circumferential columns 3 is taken as an example for illustration, but in the actual application process and within the scope of protection of this scheme, it is not limited to only three said circumferential columns 3 Column 3.
[0030] Wherein, the bottom structure 1 includes a structural shell made of metal material, where the metal material can be selected as a steel structure material, so as to effectively improve the structural strength and corrosion resistance. The interior of the structural shell is filled with concrete to provide ballast force, thereby lowering the center of the floating wind power foundation, so that the bottom node 1 sinks below the waterline surf...

The invention belongs to the technical field of ocean engineering, and provides a variable-cross-section three-stand-column type offshore floating wind power foundation which comprises a bottom structure, a center stand column arranged on the bottom structure and a plurality of circumferential stand columns arranged on the bottom structure around the center stand column. Contact sections intersecting with the water surface are arranged on the circumferential stand columns, the sectional area of the middle of each contact section is smaller than the sectional areas of the tail ends of the two ends of the contact section in the axial direction of the circumferential stand columns, and the sectional areas of the contact sections are gradually increased from the middle to the tail ends of the two ends. According to the floating type wind power foundation, the wave load and dynamic response of waves to the floating wind power foundation can be effectively reduced, and the seakeeping and power generation benefits of floating wind power are improved.
Description
technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a variable-section three-column offshore floating wind power foundation. Background technique [0002] At present, the development and utilization of offshore wind energy is gradually moving from shallow seas to deep seas. The development and utilization of wind energy in shallow seas often use fixed offshore wind turbines, but in deep seas where the water depth is greater than 50m, fixed wind turbines are no longer applicable due to poor economy and stability, while floating wind power is better because of its economy and stability. It has become an important trend in the development and utilization of deep sea wind energy. However, in the face of the complex and harsh deep sea environment, floating wind power puts forward higher requirements on the seakeeping and stability of the platform foundation. To meet this requirement, it is necessary to design a ...
