[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] The offshore wind-solar power generation device of the embodiment of the present invention comprises a floating assembly 1, a connecting assembly 2 and a power generation assembly 3. The floating assembly 1 is suitable for floating on the water surface. The floating assembly 1 comprises a first floating column 11, a second floating column 12, a third floating column 13 and a connecting column 14. The first floating column 11, the second floating column 12 and the third floating column 13 extend in the up-down direction and are arranged at intervals. Two adjacent floating columns are connected by the connecting column 14 to form an installation space 15 between the upper end and the lower end of the first floating column 11, the second floating column 12 and the third floating column 13. The connecting assembly 2 comprises a turret and a connecting member 21. The turret is installed in the first floating column 11 so that the first floating column 11 can rotate relative to the turret axis. The upper end of the connecting member 21 is connected to the turret, and the lower end of the connecting member 21 is suitable for connecting to the anchor assembly. The power generation assembly 3 is installed on the floating assembly 1, and the power generation assembly 3 is used to follow the change when the position of the floating assembly 1 changes.

[0030] Specifically, Figure 1-Figure 2 As shown, the first buoy column 11, the second buoy column 12 and the third buoy column 13 are arranged in parallel. When the float assembly 1 floats on the water, the upper ends of the first buoy column 11, the second buoy column 12 and the third buoy column 13 are located on the water surface, and the lower ends of the first buoy column 11, the second buoy column 12 and the third buoy column 13 are located below the water surface. The first buoy column 11 and the second buoy column 12 are connected by a connecting column 14, the second buoy column 12 and the third buoy column 13 are connected by a connecting column 14, and the third buoy column 13 and the first buoy column 11 are connected by a connecting column 14 to form an installation space 15. On the projection plane orthogonal to the up and down directions, the projection of the outer contour of the float assembly 1 is a triangle.

[0031] The axial direction of the turret is consistent with the up and down direction. The turret is installed in the first buoy column 11 and is rotatably connected to the first buoy column 11, so that the first buoy column 11 can rotate relative to the axial direction of the turret, and then the buoy assembly 1 rotates around the turret. The position of the turret is fixed by connecting the connecting piece 21 with the turret and the anchor assembly, and then the mooring of the first buoy column 11 is achieved through the connection between the turret and the first buoy column 11, and the first buoy column 11 is fixed in the sea.

[0032] Optionally, the connection member 21 is a tension leg or a mooring cable, and the tension leg is used in this embodiment.

[0033] The offshore wind-solar power generation device of the embodiment of the present invention connects the first floating column 11, the second floating column 12 and the third floating column 13 through the connecting column 14 to form a floating assembly 1, and a turret is arranged in the first floating column 11. The turret is connected to the anchor assembly by a connecting piece 21, which is convenient for fixing the floating assembly 1. Since the first floating column 11 is rotatable relative to the axial direction of the turret, under the action of wind load and wave load, the first floating column 11 can rotate with the wind and waves, so that the first floating column 11 is always located upstream of the second floating column 12 and the third floating column 13 in the direction of wind flow, thereby reducing the load on the floating assembly 1, thereby reducing the strength requirements of the floating assembly 1 in other directions and reducing the cost of the power generation device.

[0034] Furthermore, in this embodiment, the first buoy column 11 is moored to the target sea area by using tension legs, and the mooring radius is small, which can reduce the sea area used and improve the utilization rate of the sea area.

[0035] Furthermore, in the embodiment of the present invention, by arranging the power generation component 3 on the floating component 1, since the floating component 1 can rotate with the main wind direction, the first floating column 11 is always facing the main wind direction, which can increase the wind energy received by the power generation component 3 and improve the power generation efficiency.

[0036] In some embodiments, the connecting column 14 includes a first connecting column 141, a second connecting column 142 and a third connecting column 143, the two ends of the first connecting column 141 are respectively connected to the first floating column 11 and the second floating column 12, the two ends of the second connecting column 142 are respectively connected to the second floating column 12 and the third floating column 13, and the two ends of the third connecting column 143 are respectively connected to the third floating column 13 and the first floating column 11.

[0037] Specifically, Figure 1-Figure 3 As shown, the first connecting column 141 is arranged between the first floating column 11 and the second floating column 12 to realize the connection between the first floating column 11 and the second floating column 12. The second connecting column 142 is arranged between the second floating column 12 and the third floating column 13 to realize the connection between the second floating column 12 and the third floating column 13. The third connecting column 143 is arranged between the third floating column 13 and the first floating column 11 to realize the connection between the third floating column 13 and the first floating column 11. By setting the first connecting column 141, the second connecting column 142 and the third connecting column 143, the end-to-end connection of the first floating column 11, the second floating column 12 and the third floating column 13 is realized, so that the installation space 15 is formed, and the connection stability of the floating assembly 1 is improved.

[0038] In some embodiments, at least one of the first connecting column 141, the second connecting column 142 and the third connecting column 143 includes a top connecting column 144, a bottom connecting column 145 and a diagonal brace, the top connecting column 144 and the bottom connecting column 145 are arranged in parallel in the up and down directions, and the diagonal brace is located between the top connecting column 144 and the bottom connecting column 145.

[0039] Specifically, Figure 1-Figure 2 As shown, the first connecting column 141, the second connecting column 142 and the third connecting column 143 all include a top connecting column 144, a bottom connecting column 145 and a diagonal brace. For the convenience of description, the first connecting column 141 between the first floating column 11 and the second floating column 12 is taken as an example for description. The top connecting column 144 is arranged horizontally, one end of the top connecting column 144 is connected to the upper end of the first floating column 11, and the other end of the top connecting column 144 is connected to the upper end of the second floating column 12. One end of the bottom connecting column 145 is connected to the lower end of the first floating column 11, and the other end of the bottom connecting column 145 is connected to the lower end of the second floating column 12. The diagonal brace is arranged obliquely, one end of the diagonal brace is connected to the first floating column 11, and the other end of the diagonal brace is connected to the second floating column 12. The rigidity between the first floating column 11 and the second floating column 12 is improved by the arrangement of the diagonal brace.

[0040] Optionally, the cross-section of the floating column is circular, and the cross-sections of the top connecting column 144 and the bottom connecting column 145 are rectangular, so as to facilitate the connection between the top connecting column 144 and the bottom connecting column 145 and the floating column.

[0041] In some embodiments, the diagonal brace includes a first diagonal brace 146 and a second diagonal brace 147, and the first diagonal brace 146 and the second diagonal brace 147 are arranged crosswise, one end of the first diagonal brace 146 is connected to the upper end of one of the two adjacent floating columns, and the other end of the first diagonal brace 146 is connected to the lower end of the other of the two adjacent floating columns, one end of the second diagonal brace 147 is connected to the lower end of one floating column, and the other end of the second diagonal brace 147 is connected to the upper end of another floating body.

[0042] Specifically, Figure 1-Figure 2 As shown, the diagonal brace of the first connecting column 141 between the first floating column 11 and the second floating column 12 is also described as an example. The upper end of the first diagonal brace 146 is connected to the upper end of the second floating column 12, the lower end of the first diagonal brace 146 is connected to the lower end of the first floating column 11, the upper end of the second diagonal brace 147 is connected to the upper end of the first floating column 11, and the lower end of the second diagonal brace 147 is connected to the lower end of the second floating column 12.

[0043] The connection between the diagonal brace and the upper end of the floating column is located below the connection between the top connecting column 144 and the floating column, and the connection between the diagonal brace and the lower end of the floating column is located above the connection between the bottom connecting column 145 and the floating column, which facilitates the connection between the diagonal brace and the floating column.

[0044] In some embodiments, Figure 3-Figure 4 As shown, the floating assembly 1 also includes a frame beam 16, which is located in the installation space 15, one end of the frame beam 16 is connected to the top connecting column 144 between the first floating column 11 and the second floating column 12, and the other end of the frame beam 16 is connected to the top connecting column 144 between the first floating column 11 and the third floating column 13. The frame beam 16 is arranged at the upper end of the floating assembly 1. Through the arrangement of the frame beam 16, the top connecting column 144 between the first floating column 11 and the second floating column 12 and the top connecting column 144 between the first floating column 11 and the third floating column 13 are connected, which can improve the structural strength of the floating assembly 1.

[0045] In some embodiments, the offshore wind-solar power generation device further includes a bracket 4 , a plurality of frame beams 16 , the plurality of frame beams 16 are arranged at intervals and include a first frame beam 161 and a second frame beam 162 arranged in sequence and staggered, and the bracket 4 is mounted on the first frame beam 161 .

[0046] Specifically, Figure 3-Figure 4 As shown, the first frame beam 161 and the second frame beam 162 are evenly spaced between the first floating column 11 and the second floating column 12, and starting from the top connecting column 144 between the second floating column 12 and the third floating column 13, the plurality of frame beams 16 are sequentially the first first frame beam 161, the first second frame beam 162, the second first frame beam 161, the second second frame beam 162, the third first frame beam 161 and the third second frame beam 162. By installing the bracket 4 on the first frame beam 161, the installation of the photovoltaic module 31 is facilitated.

[0047] In some embodiments, the power generation component 3 includes a photovoltaic component 31, one end of the photovoltaic component 31 is connected to the bracket 4, and the other end of the photovoltaic component 31 is connected to the second frame beam 162 or the top connecting column 144 between the second floating column 12 and the third floating column 13.

[0048] Specifically, Figure 3-Figure 4As shown, one end of the first photovoltaic assembly 31 is mounted on the top connecting column 144 between the second floating column 12 and the third floating column 13, the other end of the first photovoltaic assembly 31 is mounted on the first first frame beam 161, one end of the second photovoltaic assembly 31 is mounted on the first first frame beam 161, the other end of the second photovoltaic assembly 31 is mounted on the first second frame beam 162, one end of the third photovoltaic assembly 31 is mounted on the first second frame beam 162, the other end of the second photovoltaic assembly 31 is mounted on the second first frame beam 161, and so on until all photovoltaic assemblies 31 are completed. Since the photovoltaic assembly 31 is installed at an angle, the photovoltaic assembly 31 has a certain installation angle, which improves the power generation efficiency of the photovoltaic assembly 31.

[0049] Optionally, the installation angle of the photovoltaic assembly 31 can be determined according to the geographical location of the sea area where the photovoltaic assembly 31 is arranged, and a suitable height of the bracket 4 can be set to increase the power generation of the photovoltaic assembly 31.

[0050] Furthermore, in this embodiment, the photovoltaic components 31 are installed by using the installation space 15 between the first floating column 11, the second floating column 12 and the third floating column 13, so as to improve the utilization rate of the sea area and further improve the power generation efficiency.

[0051] In some embodiments, Figure 1-Figure 2 As shown, the power generation assembly 3 includes a wind turbine assembly 32 , and the wind turbine assembly 32 includes a first wind turbine 321 and a second wind turbine 322 . The first wind turbine 321 is installed on the second floating column 12 , and the second wind turbine 322 is installed on the third floating column 13 .

[0052] Compared with the method of installing wind turbines on three floating columns, in this embodiment, the first wind turbine 321 is installed on the second floating column 12, and the second wind turbine 322 is installed on the third floating column 13. Since the second floating column 12 and the third floating column 13 are always located downstream of the first floating column 11 in the wind flow direction, the first wind turbine 321 and the second wind turbine 322 can absorb wind energy at the same time, avoiding the influence of the wind turbine installed on the first floating column 11 on the wind turbines on the downstream second floating column 12 and the third floating column 13, thereby increasing the power generation of the wind turbine assembly 32.

[0053] Furthermore, in this embodiment, a photovoltaic module 31 and a wind turbine module 32 are simultaneously arranged on the floating body component 1. By adjusting the capacity ratio of the photovoltaic module 31 and the wind turbine module 32, a smooth fluctuation of the power generation can be achieved, which is more friendly to the power grid. The capacity of the photovoltaic module 31 and the wind turbine module 32 can be configured according to the output characteristics so that the total output fluctuation is minimized. The electric energy generated by the photovoltaic module 31 and the wind turbine module 32 can be transmitted through a submarine cable, which saves costs. In addition, the photovoltaic module 31 is installed in the installation space 15 on the upper part of the floating body component 1, which reduces the development cost of a single energy source.

[0054] In some embodiments, Figure 1-Figure 2 As shown, the first fan 321 and the second fan 322 are vertical axis fans, and the first fan 321 and the second fan 322 rotate in opposite directions. When the first fan 321 and the second fan 322 absorb wind energy, the first fan 321 and the second fan 322 rotate. Since the rotation axes of the first fan 321 and the second fan 322 are in a vertical direction, and the first fan 321 and the second fan 322 rotate in opposite directions, an acceleration area is formed between the first fan 321 and the second fan 322, and the synergistic effect between the vertical axis fans is used to improve the power generation and power generation efficiency.

[0055] Of course, in other embodiments, the rotation directions of the first fan 321 and the second fan 322 may also be set to be the same.

[0056] In some embodiments, the first fan 321 and the second fan 322 are horizontal axis fans, and the first fan 321 and the second fan 322 have the same rotation direction. Since the rotation axes of the first fan 321 and the second fan 322 are in the horizontal direction, by setting the rotation directions of the first fan 321 and the second fan 322 to be the same, the first fan 321 and the second fan 322 can absorb wind energy at the same time, thereby improving power generation efficiency.
