[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1 to 6 As shown, an embodiment of the present invention discloses an integrated offshore wind power device, including a floating platform 100 , a wind power generation component 200 , a support truss 300 and a breeding cage 400 .

[0036] Among them, an installation space is provided inside the floating platform 100, and the installation space is connected to the outside of the floating platform 100; the wind power generation component 200 is used for wind power generation; the support truss 300 is arranged above the floating platform 100 to support the wind power generation component 200; the aquaculture cage 400 is arranged in the installation space of the floating platform 100.

[0037] When using the integrated offshore wind power device provided by the present invention, the support truss 300 is set above the floating platform 100, and the wind power generation component 200 is supported by the support truss 300. Compared with the existing single thick tube tower support, the shielding effect of the wind power generation component 200 is effectively reduced, and the wind energy utilization rate is improved; the aquaculture cage 400 is set in the installation space inside the floating platform 100. Since the installation space is connected to the outside of the floating platform 100, the seawater outside the floating platform 100 can enter the aquaculture cage 400, so as to facilitate aquaculture in the aquaculture cage 400.

[0038] It can be seen that the integrated offshore wind power device provided by the present invention realizes the co-structural integrated development of offshore wind power and offshore aquaculture by increasing the occupation of the vertical space of the ocean, thereby reducing the development cost of offshore wind power, and on the other hand improves the comprehensive utilization of offshore vertical resources, thereby improving the comprehensive utilization rate of offshore resources.

[0039] It should be understood that the floating platform 100 may be a cubic structure, a cylindrical structure, a polygonal prism structure, or the like, and any shape that can meet the requirements of use falls within the scope of protection of the present invention. Furthermore, the floating platform 100 may be connected to the outside of the floating platform 100 through a hollow structure or a connecting pipe, and any structure that can achieve communication with the outside of the floating platform 100 falls within the scope of protection of the present invention.

[0040] Optionally, the floating platform 100 provided in an embodiment of the present invention has a cubic structure, and the side walls and bottom of the cubic structure are provided with openings connected to the outside of the floating platform 100, so as to facilitate seawater to enter the aquaculture cages 400 inside the floating platform 100 for aquaculture.

[0041] In addition, a buffer structure 500 is provided on the upstream side of the aquaculture cage 400 to reduce the impact load of the ocean current on the aquaculture cage 400 and prevent the aquaculture cage 400 from being reduced in volume or damaged under the impact of the ocean current.

[0042] It should be noted that the above-mentioned buffer structure 500 can be a baffle, an elastic buffer or a specific form of buffer structure 500, etc. As long as the structure type can meet the buffering requirements, it falls within the protection scope of the present invention.

[0043] Alternatively, as Figure 1 and Figure 3 As shown, a fixing bracket 101 is provided at the opening portion of the side wall of the floating platform 100, and the above-mentioned buffer structure 500 is a cone structure. The bottom surface of the cone structure is arranged parallel to the side wall of the floating platform 100, and the bottom surface of the cone structure is connected to the fixing bracket 101 to fix the cone structure on the upstream side of the aquaculture cage 400. The ocean current is diverted through the side of the cone structure to reduce the phenomenon of the ocean current directly impacting the aquaculture cage 400, effectively reduce the load of the ocean current on the aquaculture cage 400, and prevent the aquaculture cage 400 from being reduced in volume or damaged under the impact of the ocean current.

[0044] The cone structure provided by the present invention can be in the shape of a triangular pyramid, a circular cone or a polygonal pyramid. As long as the structural form can meet the use requirements, it falls within the protection scope of the present invention; optionally, the cone structure provided in the embodiment of the present invention is a quadrangular pyramid structure.

[0045] Furthermore, the present invention does not impose any specific restrictions on the number and size parameters of the above-mentioned cone structures. In practical applications, the number and size parameters of the cone structures can be adaptively adjusted according to factors such as the specific marine environment and the size of the aquaculture cage 400. As long as the number and size parameters can meet the use requirements, they are within the protection scope of the present invention.

[0046] like Figures 1 to 3As shown, the support truss 300 includes a first truss 301, a second truss 302, a third truss 303 and a fourth truss 304. The floating platform 100 has a cube structure. The first truss 301, the second truss 302, the third truss 303 and the fourth truss 304 are respectively arranged at four right-angled areas on the top of the cube structure; the first truss 301 and the second truss 302 are located on one side of the wind turbine assembly 200 to support one end of the wind turbine assembly 200, and the third truss 303 and the fourth truss 304 are located on the other side of the wind turbine assembly 200 to support the other end of the wind turbine assembly 200, so as to reduce the obstruction of the wind rotor of the wind turbine assembly 200 and improve the utilization rate of wind energy.

[0047] Furthermore, the floating platform 100 is fixed to the seabed via a single point mooring assembly 600 , so that the floating platform 100 can rotate around the underwater mooring point according to the wind direction and the ocean current direction.

[0048] Specifically, if Figure 1 As shown, the single-point mooring assembly 600 includes a single-point mooring component 601, a mooring line 602 and an anchoring foundation 603. The mooring line 602 connects the floating platform 100 and the single-point mooring component 601. The single-point mooring component 601 is fixed to the seabed through the anchoring foundation 603, so that the above-mentioned floating platform 100 can rotate around the single-point mooring component 601 according to the wind direction and the current direction.

[0049] like Figures 4 to 6 As shown, the aquaculture cage 400 includes an inner net 401 and an outer net 402 arranged on the outside of the inner net 401. The outer net 402 is rigidly fixed to the floating platform 100 to prevent attacks from large fish such as sharks and whales through the outer net 402; the inner net 401 is flexibly fixed to the floating platform 100 through a cable 4011 to culture fish through the inner net 401.

[0050] In addition, the floating platform 100 provided by the present invention is further provided with an azimuth propeller 700 to assist in adjusting the orientation of the floating platform 100 through the azimuth propeller 700, so as to facilitate the wind power generation assembly 200 to capture wind energy.
