Example Embodiment
[0042] Example one
[0043] like figure 1As shown, the semi-submersible wind power based platform includes an infrastructure platform, a fan tower 4, a wind turbine 5, a umbilical cable 9 and a positioning system; the infrastructure platform includes a column 1, a horizontal floating box 2, a central floating box 3. Connect the floating box 6 and the slider 7, the central floating box 3 on the top of the infrastructure platform is connected to the fan tower 4, and the top of the infrastructure platform supports the facility of the balancing device, three columns 1 perpendicular to the water surface, column 1 There is a horizontal floating box 2 between the center floating box 3, and the lower portion of the three columns 1 is connected by connecting the floating box 6. The bottom of the base structure is in the form of a positive triangular structure, and the bottom of the center floating box 3 is connected to the umbilical cord connected to the undergarment power line. Cable 9; t...
Example Embodiment
[0052] Example 2
[0053] like Figure 9 As shown, the installation method of the semi-subtiled wind power base platform includes the following steps:
[0054] S1, as an anchoring device 10 at the bottom of the anchor chain (anchor system 8), pre-adopted a pile or mounting suction anchor.
[0055] S2, after the pile or suction anchor is installed, the anchor chain and the cable are arranged along the predetermined route in the seabed, and after completing the anchor chain, do the corresponding marker and discard the cable.
[0056] S3, the infrastructure platform is built within the dock, which has caused the infrastructure platform to float.
[0057] S4, using a crane on the shore to install the fan tower 4, the cabin and the wind wheel (wind turbine 5), and the fanding foundation is formed with the infrastructure platform.
[0058] S5, the installed fan foundation
[0059] S6, connect pre-laying anchor chains and infrastructure platforms: Each anchor chain needs to be restored to...

Abstract
The invention relates to a semi-submersible wind power generation foundation platform which comprises a foundation structure platform, a fan tower, a wind generating set, an umbilical cable and a positioning system. A center part at the top of the foundation structure platform is a center buoyancy tank, the upper portion of the center buoyancy tank is connected with the fan tower, and the wind generating set is arranged at the top of the fan tower. A stand column perpendicular to the water surface is arranged outside the central buoyancy tank at the top of the foundation structure platform, and a horizontal buoyancy tank is arranged between the stand column and the central buoyancy tank; the lower portions of the adjacent stand columns are connected through connecting buoyancy tanks, and heaving plates are arranged at the bottom ends of the stand columns. The bottom of the foundation structure platform is of a regular triangle structure. The bottom of the central buoyancy tank is connected with the umbilical cable connected with a seabed power line. The foundation platform has the beneficial effects that the foundation platform is simple and reasonable in structure, the wind generating set has symmetry relative to arrangement of the foundation structure platform, interchangeability of structural components and an anchoring system is high, standardization of the foundation platform structure is facilitated, and the construction cost is reduced.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to an offshore semi-submersible wind power generation foundation platform and an installation method thereof. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. With the development of onshore wind power resources, the high-quality wind power resources that can be developed in China are gradually decreasing. The potential development of offshore wind power is huge, and the coastal areas are economically developed and have a large energy demand. Therefore, it is necessary to actively develop offshore wind power projects. [0003] The advantages of offshore wind power: First, the offshore wind speed is relatively high and the annual utilization rate is high. The second is that the sea area is vast, allowing large-scale wind turbines, and the power generation capacity of a sing...
