[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] See Figure 1 and Figure 2 The floating power generation device shown in the figure includes a floating structure 1 and an energy capture device 2 disposed on the floating structure 1. The floating structure 1 includes a main area 11 and multiple extension areas 12. The multiple extension areas 12 extend outward from the main area 11 to increase the effective load-bearing area of ​​the floating structure 1. The energy capture device 2 includes a main wind energy capture device 21, an auxiliary wind energy capture device 22, multiple solar energy capture devices 23 and multiple hydropower capture devices 24. The main wind energy capture device 21 is arranged in the main area 11, and the auxiliary wind energy capture device 22, solar energy capture device 23 and hydropower capture device 24 are arranged in the extension areas 12.

[0027] The floating power generation device of the present invention includes a floating structure 1 and an energy capture device 2. The main body area 11 is used to house the main wind energy capture device 21, and the extension area 12 is used to house the auxiliary wind energy capture device 22, the solar energy capture device 23, and the hydropower capture device 24. The arrangement of the extension area 12 not only increases the load-bearing area of ​​the floating structure 1 but also improves the load-bearing strength of the entire floating power generation device. Furthermore, because the load-bearing area of ​​the floating structure 1 is increased, it can support multiple types of energy capture devices 2, thus improving the versatility of energy capture.

[0028] It should be noted that the main body area 11 has a top surface, a bottom surface, and a peripheral surface connecting the top and bottom surfaces, wherein the top and bottom surfaces are arranged opposite to each other. The bottom and peripheral surfaces of the main body area 11 are located below the sea surface, while the top surface is exposed above the sea surface to support the main wind energy capture device 21. The main body area 11 can be a cylindrical structure, a cubic structure, a frustum structure, a truncated cone structure, etc.

[0029] The main area 11 may include a main platform 111, which is located on the top surface of the main area 11 to form a structure that carries the main wind energy capture device 21.

[0030] The shape of the main platform 111 is adjusted according to the shape of the main body area 11. For example, when the main body area 11 is a cylindrical structure, the main platform 111 as a whole is cylindrical.

[0031] The main platform 111 may form part or all of the top surface of the main body area 11. When the main platform 111 forms the entire top surface of the main body area 11, the main platform 111 is a complete plate structure. When the main platform 111 forms only part of the top surface of the main body area 11, the top surface of the main body area 11 is a structure combining the main platform 111 and a frame to reduce the weight of the main body area 11. Specifically, the main body area 11 may also include a plurality of first connecting beams 113 located on the top surface of the main body area 11. The first connecting beams 113 extend outward from the main platform 111 to form a top frame structure.

[0032] To understand this solution, the first connecting beam 113 has a first end connected to the main platform 111 and a second end extending in all directions. The first end of the first connecting beam 113 and the main platform 111 are either an integral structure or a separate structure. In the case where the first connecting beam 113 and the main platform 111 are an integral structure, the main platform 111 and the multiple first connecting beams 113 are processed from a single sheet metal. In the case where the first connecting beam 113 and the main platform 111 are separate structures, the main platform 111 and the first end of the first connecting beam 113 are connected by welding or by fasteners.

[0033] Multiple first connecting beams 113 are evenly arranged on the outer periphery of the main platform 111. This can be understood as the distance between the first ends of any two adjacent first connecting beams 113 being equal.

[0034] In the diagram, the main platform 111 has a hexagonal structure, and there are six first connecting beams 113. One first connecting beam 113 is located at each corner of the main platform 111, thus forming six top frame structures around the main platform 111. Furthermore, the top frame structures are trapezoidal. It should be noted that the main platform 111 is a steel structure, and its surface has an anti-corrosion coating.

[0035] The above mainly describes the structure of the main platform 111. In some examples of this invention, the circumferential surface of the main body area 11 can be a closed structure or an open structure. Specifically, the main body area 11 may also include a second connecting beam 114. The second connecting beam 114 is located on the circumferential surface of the main body area 11 to form the circumferential surface of the main body area 11. The second connecting beam 114 can extend along the height direction of the main body area 11 to support the main body area 11 in the height direction, or it can be arranged at an angle relative to the circumferential direction of the main body area 11, or it can extend along the circumferential direction of the main body area 11. The height direction is perpendicular to the circumferential direction.

[0036] Given that the top surface of the main body area 11 includes the main platform 111 and the first connecting beam 113, the periphery of the main body area 11 includes a plurality of second connecting beams 114. Parts of the plurality of second connecting beams 114 are connected to the second ends of the adjacent first connecting beams 113, and together with the remaining second connecting beams 114, they form a side frame structure.

[0037] In this example of the invention, the peripheral surface of the main body area 11 also includes a side plate 112, which is located in the middle of the side frame structure.

[0038] To further optimize the above solution, in some embodiments of the present invention, there is an opening on the periphery of the main body area 11, so that the part of the main body area 11 located below the sea surface can be used to arrange net cages to form a fish farming area, thereby further expanding the function of the floating power generation device.

[0039] The extension area 12 extends radially from the main body area 11 to increase the load-bearing area and load-bearing strength of the floating structure 1. The extension area 12 surrounds the main body area 11 and includes multiple connecting rods 121 and multiple floats 122. The connecting rods 121 connect the circumference of the main body area 11 to the floats 122.

[0040] In some examples, a connecting rod 121 is provided with one or more pontoons 122. In the illustration, a connecting rod 121 is provided with two pontoons 122. Therefore, the extension area 12 is divided into two extension areas 12, namely the first extension area A and the second extension area B, wherein the first extension area A is located between the second extension area B and the main body area 11. The division between the first extension area A and the second extension area B is the boundary of the pontoons 122.

[0041] In some examples, of the two pontoons 122 on all connecting rods 121, the pontoons 122 closer to the main body area 11 are generally on the same circle, and the pontoons 122 farther from the main body area 11 are generally on the same circle.

[0042] Furthermore, in order to reduce the interference caused by the arrangement of the energy capture device 2 on adjacent pontoons 122, the distance between the pontoon 122 closer to the main body area 11 and the main body area 11 shall not be less than 20m.

[0043] In some examples, the distance between two floats 122 on the same connecting rod 121 is not less than 20m.

[0044] To improve the service life of the extension area 12, the extension area 12 is made of corrosion-resistant material.

[0045] Furthermore, the aforementioned floating structure 1 may also include an anchoring structure, through which the floating structure 1 can be positioned in the sea area. The anchoring structure may be set in the main area 11 and / or the extension area 12.

[0046] The energy capture device 2 of the present invention includes a main wind energy capture device 21, an auxiliary wind energy capture device 22, a plurality of solar energy capture devices 23 and a plurality of hydropower capture devices 24.

[0047] To increase the energy density captured by the aforementioned energy capture device 2, the main wind energy capture device 21 is located in the main area 11 and has the highest height, used to capture wind energy at higher locations. The auxiliary wind energy capture device 22, located in the extension area 12, has a lower height than the main wind energy capture device 21 and is used to capture wind energy at lower locations.

[0048] Auxiliary wind energy capture device 22, solar energy capture device 23 and hydro energy capture device 24 are arranged in the extension area 12, and they can be arranged in a regular pattern or arbitrarily.

[0049] In the diagram, solar energy capture devices 23 are arranged on pontoons 122 in the first extension zone A, with one solar energy capture device 23 arranged on each pontoon 122; auxiliary wind energy capture devices 22 are arranged on pontoons 122 in the second extension zone B, with one auxiliary wind energy capture device 22 arranged on each pontoon 122; and hydropower capture devices 24 are arranged below pontoons 122 in the second extension zone B, with one auxiliary wind energy capture device 22 arranged on each pontoon 122.

[0050] Of course, in some other examples of the present invention, a water energy capture device 24 may also be arranged below the buoy 122 located in the second extension area B to further improve the energy capture density of the floating power generation device.

[0051] It should be noted that the above-mentioned extension area 12 is divided into two extension areas 12 according to the arrangement of the floats 122. In some examples of the present invention, the number of floats 122 can be further increased, or the number of floats 122 can be further reduced to arrange one extension area 12.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. 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 the invention. Therefore, the invention 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.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
