However, different sea depths and different turbine models have significant differences in the requirements for platform buoyancy configuration, structural dimensions, etc., which usually require different platforms to be customized for different needs, resulting in customized designs of "one turbine, one model; one site, one model".

[0040] like Figures 1-7 As shown in the embodiment of this application, the floating wind power platform includes a central column 100, side columns 200, and pontoons 300. The central column 100 is used to support the power generation components, and the side columns 200 are connected to the central column 100 through the pontoons 300. The pontoons 300 are formed by splicing at least two modular components 310. The modular components 310 can be adjusted in size along at least one direction, so that the overall size of the pontoons 300 can be adjusted. The buoyancy configuration and structural size of the platform can be adjusted by adjusting the size of the pontoons 300, so that the platform can adapt to the needs of different sea depths and different turbine models, thereby improving the applicability of the platform and reducing manufacturing costs.

[0041] In some embodiments, the pontoon 300 can be formed by sequentially splicing together two, three, four or more modular components 310, so that the size of the pontoon 300 can be adjusted according to the number of modular components 310 along the distribution direction of the modular components 310 to accommodate different distances between the central column 100 and the side column 200. The number of modular components 310 can be selected according to actual needs, and this application embodiment does not limit this.

[0042] In this application, such as Figure 1 As shown, the power generation component can be a wind turbine 600, which captures wind energy to generate wind power.

[0043] like Figures 4-5 As shown, the module component 310 includes a first connecting plate 311, a second connecting plate 312, and a connecting rounded corner plate 313.

[0044] There are two first connecting plates 311, which are distributed vertically opposite each other, so that the two first connecting plates 311 form the top and bottom surfaces of the float 300 respectively. Since the central column 100 supports the wind turbine 600, the alternating loads generated by the yaw, torsion, pitch and other forces of the wind turbine 600 during operation are transmitted to the float 300 through the central column 100 to form shear force, axial force and bending moment loads. The first connecting plates 311 bear the shear force, axial force and bending moment loads transmitted to the float 300, and the buoyancy configuration can be adjusted by adjusting the size of the first connecting plates 311.

[0045] There are two second connecting plates 312, which are distributed opposite each other on both sides, so that the two second connecting plates 312 form the side wall of the float 300, and together with the first connecting plate 311, they bear the loads such as shear force, axial force and bending moment transmitted to the float 300.

[0046] There are four connecting rounded corner plates 313. The four connecting rounded corner plates 313 are connected to the first connecting plate 311 and the second connecting plate 312 in sequence to form a modular component 310, and to form a smooth transition structure between the first connecting plate 311 and the second connecting plate 312, thereby reducing the risk of local stress concentration and hydrodynamic separation caused by geometric abrupt changes.

[0047] In this application, the connecting rounded corner plate 313 is connected to the first connecting plate 311 and the second connecting plate 312 through a standardized structure to improve the applicability of the connecting rounded corner plate 313 and the convenience of the assembly process, while also making the connecting rounded corner plate 313 applicable to different platforms.

[0048] In some embodiments, the connecting rounded corner plate 313 is connected to the first connecting plate 311 and the second connecting plate 312 via flanges.

[0049] In some other embodiments, the rounded corner plate 313 is connected to the first connecting plate 311 and the second connecting plate 312 by bolts.

[0050] In some other embodiments, the rounded corner plate 313 is welded to the first connecting plate 311 and the second connecting plate 312 after beveling.

[0051] Of course, the connecting rounded corner plate 313 can also be bonded and fixed to the first connecting plate 311 and the second connecting plate 312 with epoxy resin splicing adhesive. In actual situations, the connection method can be selected according to the requirements, and this application embodiment does not limit this.

[0052] like Figures 4-5 As shown, the cross-section of the first connecting plate 311 is π-shaped, which allows the vertical plates of the two first connecting plates 311 to abut against each other. After being assembled into the module component 310, the two abutting first connecting plates 311 can form a reinforcing plate to improve the structural strength of the pontoon 300.

[0053] The second connecting plate 312 is a flat plate structure. It is connected to the first connecting plate 311 and the second connecting plate 312 by connecting rounded corner plate 313, so that the module component 310 forms a hollow structure. In practice, some seawater can be filled into the hollow pontoon 300 to lower the overall center of gravity of the platform and improve the stability of the platform.

[0054] In some embodiments, such as Figures 4-5As shown, the first connecting plate 311 can be sized to be adjusted along the first direction. Specifically, multiple sizes of the first connecting plate 311 can be made so that the different sizes of the first connecting plates 311 along the first direction are different, and they can be spliced ​​into modular components 310 of different sizes.

[0055] like Figures 4-5 As shown, the second connecting plate 312 can be sized to be adjusted along the second direction. Specifically, multiple sizes of second connecting plates 312 can be manufactured so that different second connecting plates 312 have different sizes along the second direction, and can be spliced ​​into modular components 310 of different sizes.

[0056] Since the first connecting plate 311 can be adjusted in size along the first direction, the second connecting plate 312 can be adjusted in size along the second direction, and the connecting rounded corner plate 313 can be a constant size, the connecting rounded corner plate 313 can be made into a standard part to reduce the manufacturing cost caused by the complex manufacturing process of the connecting rounded corner plate 313, and further reduce the manufacturing cost.

[0057] In this way, by adjusting the size of the first connecting plate 311 in the first direction and the size of the second connecting plate 312 in the second direction, different sizes of modular components 310 can be obtained. By splicing different numbers of modular components 310, the size of the pontoon 300 can be adjusted in the length, width and height directions to meet different needs.

[0058] like Figures 3-5 As shown, prestressed tendon channels 314 are provided in the first connecting plate 311, the connecting rounded corner plate 313, and the second connecting plate 312. After assembling the first connecting plate 311, the connecting rounded corner plate 313, and the second connecting plate 312 into a modular component 310, adjacent modular components 310 are bonded and fixed together, and prestressed tendons are passed through the prestressed tendon channels 314 to achieve the splicing of multiple modular components 310 to form a float 300, thereby improving the overall structural strength of the float 300 and ensuring the stability of the platform.

[0059] like Figures 6-7 As shown, a bevel is provided on the module assembly 310 located at the edge of the pontoon 300 and connected to the central column 100 and the side column 200, so that the module assembly 310 can be welded and fixed to the central column 100 and the side column 200 after being positioned by the bevel, so as to realize the connection between the central column 100, the side column 200 and the pontoon 300.

[0060] It is understandable that, such as Figures 2-3 , Figures 6-7As shown, in actual practice, after the pontoon 300 is assembled, it is first welded to the connecting module of the central column 100 and the connecting module of the side column 200. Then, the connecting module is installed on the central column 100 and the side column 200 respectively. Therefore, after the size of the pontoon 300 is adjusted, the size of the connecting module can be adjusted according to the pontoon 300 to ensure the stability of the connection and the stable operation of the platform.

[0061] like Figure 1 As shown, a first damping plate 410 and a second damping plate 420 are welded between the central column 100 and the side column 200. There is an interlayer hollow space between the first damping plate 410 and the second damping plate 420, so that the float 300 is located between the first damping plate 410 and the second damping plate 420. The first damping plate 410 and the second damping plate 420 form an energy dissipation system that bears hydrodynamic loads.

[0062] In this application, a first damping hole is formed on the first damping plate 410, and a second damping hole is formed on the second damping plate 420. The projections of the first damping hole and the second damping hole in the vertical direction do not coincide at least partially, forming a staggered opening to prevent the fluid from forming a "straight-through flow channel" during heave motion. When the platform undergoes heave motion, the fluid needs to pass through the first damping hole in the upper layer firstly, and then undergo deflection, backflow, and redistribution in the interlayer space before it can pass through the second damping hole in the lower layer. The flow path is significantly lengthened, and the local pressure difference and vortex dissipation are enhanced, thereby improving the equivalent heave damping.

[0063] In some embodiments, the centers of the first damping orifice and the second damping orifice may not coincide to form a staggered distribution.

[0064] In some other embodiments, the regions of the first damping orifice and the second damping orifice may be offset radially or circumferentially to form a misaligned distribution.

[0065] In some embodiments, the first damping hole is one or more combinations of a circular hole, an oblong hole, a slotted hole, and a polygonal hole, which can be selected according to the actual situation. This application embodiment does not limit this.

[0066] In some embodiments, the second damping hole is one or more combinations of a circular hole, an oblong hole, a slotted hole, and a polygonal hole, which can be selected according to the actual situation. This application embodiment does not limit this.

[0067] The equivalent heave damping can be further improved by using various combinations of the first damping orifice and the second damping orifice.

[0068] In this application, there are at least three side columns 200, which are evenly distributed along the circumference of the central column 100, and there are also at least three pontoons 300, so that the pontoons 300 correspond one-to-one with the side columns 200.

[0069] For example, such as Figure 1 As shown, there are three side columns 200 and three pontoons 300, and the included angle between adjacent side columns 200 is 120° to ensure the overall stability of the platform.

[0070] Of course, in other embodiments, there may be four, five or more side columns 200, which can be selected according to the actual situation. This application embodiment does not limit this.

[0071] like Figure 1 As shown, the floating wind power platform provided in this application embodiment also includes a mooring cable 500. The mooring cable 500 is connected to the lower surface of the side column 200 or the edge of the buoy 300, and the platform is anchored through the mooring cable 500. Specifically, one end of the mooring cable 500 is connected to the lower surface of the side column 200 or the edge of the buoy 300, and the other end is connected to the seabed anchoring foundation. Each side column 200 or buoy 300 is connected to at least two mooring cables 500, and the at least two mooring cables 500 extend radially to form multi-point mooring, which can effectively limit the horizontal position and yaw motion of the platform.

[0072] For example, two, three or more mooring cables 500 may be connected to each side post 200 or buoy 300, which can be selected according to actual needs. This application embodiment does not limit this.

[0073] In this application, the mooring cable 500 can be a steel chain, synthetic fiber cable or composite cable, and can be selected according to the water depth and sea conditions. This application does not limit this.

[0074] The floating wind power platform provided in this application embodiment forms a pontoon 300 by splicing modular components 310. By adjusting the size of the first connecting plate 311 in the first direction and the size of the second connecting plate 312 in the second direction, modular components 310 of different sizes and specifications can be obtained. By splicing different numbers of modular components 310, the pontoon 300 can be adjusted in length, width, and height. The buoyancy configuration and structural dimensions of the platform can be adjusted by adjusting the size of the pontoon 300, so that the platform can adapt to the needs of different sea depths and different turbine models, thereby improving the applicability of the platform and reducing manufacturing costs.

[0075] The above description of the embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
