[0034] The parts and specific details of the photovoltaic support hoisting structure of the offshore photovoltaic of the present disclosure will be described in detail as follows:

The first truss 111 is the main structure of the first cross beam 11, and the first truss 111 can be a support beam structure formed by multiple rod members through welding, riveting or bolt connection, and the first truss 111 can be a steel truss or an aluminum alloy truss. The first truss 111 can be made of high-strength alloy steel or aluminum alloy material to ensure sufficient load-bearing capacity and wind pressure resistance. The cross-sectional shape of the first truss 111 can be rectangular, I-shaped or polygonal to reduce weight while enhancing the stability and bending resistance of the structure.

[0039] The first fixed portion 112 and the second fixed portion 113 are respectively arranged at two ends of the first truss 111, and the first fixed portion 112 and the second fixed portion 113 can serve as key nodes connecting the first cross beam 11 and the first sling 2. The materials of the first fixed portion 112 and the second fixed portion 113 can be metal, alloy or stainless steel, etc., and the first fixed portion 112 and the second fixed portion 113 can both be in block shape and can be respectively welded with the end faces of the end portions of the first truss 111, or the first truss 111, the first fixed portion 112 and the second fixed portion 113 can be an integral structure.

[0040] The second cross beam 12 can include a second truss 121, and a third fixed portion 122 and a fourth fixed portion 123 respectively arranged at two ends of the second truss 121. The second truss 121 is the main structure of the second cross beam 12, and the second truss 121 can be a support beam structure formed by multiple rod members through welding, riveting or bolt connection, and the second truss 121 can be a steel truss or an aluminum alloy truss. The second truss 121 can be made of high-strength alloy steel or aluminum alloy material to ensure sufficient load-bearing capacity and wind pressure resistance. The cross-sectional shape of the second truss 121 can be rectangular, I-shaped or polygonal to reduce weight while enhancing the stability and bending resistance of the structure.

[0041] The third fixed portion 122 and the fourth fixed portion 123 are respectively arranged at two ends of the second truss 121, and the third fixed portion 122 and the fourth fixed portion 123 can serve as key nodes connecting the second cross beam 12 and the first sling 2. The materials of the third fixed portion 122 and the fourth fixed portion 123 can be metal, alloy or stainless steel, etc., and the third fixed portion 122 and the fourth fixed portion 123 can both be in block shape and can be respectively welded with the end faces of the end portions of the second truss 121, or the second truss 121, the third fixed portion 122 and the fourth fixed portion 123 can be an integral structure.

[0042] In an exemplary embodiment of the present disclosure, please continue to refer to Figure 1 and Figure 2As shown, the first truss 111 and the second truss 121 are each provided with a plurality of reinforcing portions 8, for example, the reinforcing portions 8 can be sleeved in the first truss 111 or the second truss 121, thereby enhancing the support strength of the first truss 111 and the second truss 121. The plurality of reinforcing portions 8 can be distributed at equal intervals along the length direction of the first truss 111 or the second truss 121, and the reinforcing portions 8 can be located in the main stress area of the first truss 111 and the second truss 121.

[0043] The shape and size of the reinforcing portion 8 are matched with the cross-sectional shape and size of the truss (for example, the first truss 111 or the second truss 121) cooperating therewith. For example, the cross section of the first truss 111 and the second truss 121 is rectangular, the reinforcing portion 8 can be rectangular, and the length of each side of the reinforcing portion 8 is equal to the length of each side of the first truss 111. For example, the reinforcing portion 8 can include a plurality of rectangular plates, which can be embedded in the first truss 111 or the second truss 121, and welded with the frame of the first truss 111 or the second truss 121; or the reinforcing portion 8 can include a plurality of rod portions, which can surround the rectangular reinforcing portion 8, and each rod portion of the rectangular reinforcing portion 8 is connected between different rod members of the first truss 111 or the second truss 121 distributed adjacent to each other.

[0044] In some embodiments of the present disclosure, the reinforcing portion 8 and the main body of the first truss 111 or the second truss 121 can be connected by welding or bolt connection, etc., to ensure that they can form an integral whole and jointly bear external loads.

[0045] In some embodiments of the present disclosure, the first connecting rod 13 and the second connecting rod 14 can be connected between the first cross beam 11 and the second cross beam 12. The first connecting rod 13 and the second connecting rod 14 can be arranged at intervals and distributed in parallel. The materials of the first connecting rod 13 and the second connecting rod 14 can be high-strength and corrosion-resistant materials, and can be connected between the first cross beam 11 and the second cross beam 12 by welding, bolt connection or hinging, etc. For example, the first connecting rod 13 can be connected between the first fixed portion 112 and the third fixed portion 122, and at the same time, the second connecting rod 14 can be connected between the second fixed portion 113 and the fourth fixed portion 123.

[0046] In some embodiments of the present disclosure, the first cross beam 11, the second cross beam 12, the first connecting rod 13 and the second connecting rod 14 can form a rectangular beam body 1. The first cross beam 11 and the second cross beam 12 can be supported by the first connecting rod 13 and the second connecting rod 14. The design of the first connecting rod 13 and the second connecting rod 14 not only helps to maintain a stable distance between the first cross beam 11 and the second cross beam 12, preventing the first cross beam 11 and the second cross beam 12 from being displaced laterally due to wave impact or wind force, but also provides additional support when the first cross beam 11 and the second cross beam 12 are subjected to bending force, thereby helping to enhance the bending moment and fatigue resistance of the entire beam body 1. In some embodiments of the present disclosure, length adjustment devices can also be provided on the first connecting rod 13 and the second connecting rod 14, so as to adjust the distance between the first cross beam 11 and the second cross beam 12 according to actual needs, so as to adapt to photovoltaic supports of different sizes and weights.

[0047] Please continue to see Figure 2 As shown, a plurality of first lifting belts 2 can be connected to the same side of the beam body 1 (for example, the side of the beam body 1 away from the sea surface). The first lifting belts 2 can be in the form of strips or flat belts, and the material thereof can be high-strength and corrosion-resistant material, so as to resist the erosion of harsh marine environment and the irradiation of ultraviolet rays. For example, the first lifting belts 2 can be steel ropes or cables, and in order to further enhance the durability thereof, a waterproof and corrosion-resistant coating can be coated on the surface of the first lifting belts 2. The plurality of first lifting belts 2 can be distributed along the circumference of the beam body 1, so as to ensure the stability during hoisting and avoid potential safety hazards caused by excessive force on a single point.

[0048] Please continue to see Figures 1-3 As shown, the ends of the plurality of first lifting belts 2 away from the beam body 1 can be connected to the same point (i.e., the connection point 7). The connection point 7 of each first lifting belt 2 can be a reinforced lifting ring or lifting bracket, and the material thereof can be high-strength stainless steel, so as to ensure that it can withstand the combined force of all the first lifting belts 2. Each first lifting belt 2 can be connected to the connection point 7 by using an adjustable locking device, such as a screw buckle or a quick release buckle. Such a design not only allows the tension of the first lifting belts 2 to be adjusted as needed, but also allows the hoisting state to be quickly released in an emergency, thereby facilitating a quick response to sudden marine conditions.

[0049] In an exemplary embodiment of the present disclosure, the lengths of each of the first lifting belts 2 are equal, and the orthogonal projection of the connection point 7 of each first lifting belt 2 away from the beam body 1 on the beam body 1 is located at the center of the beam body 1. Such a design ensures uniform force distribution during hoisting, avoids deformation of the beam body 1 or instability of the hoisting system caused by uneven force distribution, helps to improve the stability and safety during hoisting, and allows the entire hoisting system to uniformly bear the weight of the hoisted object, thereby avoiding potential risks caused by uneven force distribution.

[0050] It should be noted that the length of the first sling 2 can be accurately calculated according to the weight, size of the object to be hoisted (for example, the photovoltaic support) and the safety margin in the hoisting process, and the length of the first sling 2 needs to ensure that all the first slings 2 can maintain the same tension during hoisting, so as to avoid any single point force being too large and ensure the stability and safety of the entire hoisting system.

[0051] The diameter (or width and thickness) of the first sling 2 is large enough to disperse the pressure in the hoisting process, reduce the stress concentration of the contact surface between the first sling 2 and the beam body 1 or the hoisted object, and prevent the first sling 2 from being worn or broken due to long-term stress. Specifically, the diameter or width of the first sling 2 can be tens of millimeters to hundreds of millimeters, and the specific value depends on the specific requirements and design standards of the hoisting system.

[0052] In an exemplary embodiment of the present disclosure, as shown in Figure 2 and Figure 4 The photovoltaic support hoisting structure of the offshore photovoltaic power station of the present disclosure can further include at least four first arc-shaped shackles 4, which can be made of high-strength alloy materials and have strong load-bearing capacity and corrosion resistance. Please continue to refer to Figure 4 As shown in the figure, the first arc-shaped shackle 4 can include a first fixed plate 41 and a first connecting plate 42 arranged on the first fixed plate 41, and the first connecting plate 42 can be arranged perpendicular to the first fixed plate 41. The first connecting plate 42 can be provided with a first connecting hole 421, which can penetrate the first connecting plate 42 along the thickness direction of the first connecting plate 42. The shape of the first connecting hole 421 can be circular, oval, polygonal or irregular, and the shape of the first connecting hole 421 is not specially limited here.

[0053] The first arc-shaped shackle 4 can serve as a connecting bridge between the beam body 1 and the first sling 2. For example, each first sling 2 is connected with a different first arc-shaped shackle 4, that is, the first sling 2 can be connected with the beam body 1 through the first arc-shaped shackle 4, and at this time each first sling 2 can independently bear part of the weight of the hoisted object and uniformly transmit the force to the beam body 1 through the first arc-shaped shackle 4.

[0054] In some embodiments of the present disclosure, the four first arc-shaped shackles 4 can be arranged on the first fixed portion 112, the second fixed portion 113, the third fixed portion 122 and the fourth fixed portion 123 in the beam body 1, respectively. For example, the first fixed plates 41 of the four first arc-shaped shackles 4 can be fixed on the first fixed portion 112, the second fixed portion 113, the third fixed portion 122 and the fourth fixed portion 123, respectively, by welding or bolt connection or the like. Each first sling 2 can be connected with the first connecting hole 421 of a different first arc-shaped shackle 4.

[0055] Please continue to refer to Figure 2 andFigure 3 As shown, a plurality of second lifting belts 3 are connected to the side of the beam body 1 away from the first lifting belt 2 and are distributed along the circumference of the beam body 1, and the second lifting belts 3 are used for detachable connection with the photovoltaic support. The second lifting belts 3 can be flat belts or ropes, so as to reduce wind resistance during hoisting and ensure sufficient strength and flexibility.

[0056] The material of the second lifting belts 3 can be high-strength, wear-resistant and corrosion-resistant synthetic fiber material (such as polyester fiber, nylon, etc.) or high-strength steel wire rope, so as to ensure stable performance in a harsh marine environment.

[0057] In some embodiments of the present disclosure, one end of each second lifting belt 3 can be connected to the beam body 1, and the end of each second lifting belt 3 away from the beam body 1 is provided with a corresponding connecting device, such as a buckle, a hook 61 or a quick release buckle, so as to be quickly and reliably connected with the corresponding interface on the photovoltaic support. When hoisting the photovoltaic support, each second lifting belt 3 can work cooperatively to stably hoist the photovoltaic support and keep the photovoltaic support in a balanced state through the pulling force at different positions.

[0058] In some embodiments of the present disclosure, in order to monitor the tension of each second lifting belt 3 in real time, a tension indicator or sensor can be installed on the second lifting belt 3, so as to timely find and adjust any imbalance or overload. In the present disclosure, a protective sleeve or wear-resistant pad can also be added at the position where the second lifting belt 3 contacts the photovoltaic support, so as to reduce friction and wear, thereby protecting the photovoltaic support and the second lifting belt 3 from damage.

[0059] In an exemplary embodiment of the present disclosure, the number of second lifting belts 3 is at least four, and the four second lifting belts 3 can be connected at the positions of the four corners of the rectangular beam body 1. During hoisting of the photovoltaic support, the photovoltaic support can be connected by the at least four second lifting belts 3 at the same time, and each second lifting belt 3 can work cooperatively to evenly distribute the lifting force for the photovoltaic support, so as to reduce the situation of local stress concentration and improve hoisting safety. Simultaneous connection of the four second lifting belts 3 with the photovoltaic support can ensure that the photovoltaic support can be kept stable during hoisting, avoiding shaking or tilting, thereby protecting the photovoltaic support from damage.

[0060] In an exemplary embodiment of the present disclosure, the photovoltaic support hoisting structure of the offshore photovoltaic can further include at least four second bow shackles 5, and the four second bow shackles 5 are respectively arranged on the first fixed part 112, the second fixed part 113, the third fixed part 122 and the fourth fixed part 123 and are located on the side of the beam body 1 away from the first lifting belt 2; and each second lifting belt 3 is connected with a different second bow shackle 5. For example, the four second bow shackles 5 can be welded or connected by bolts with the first fixed part 112, the second fixed part 113, the third fixed part 122 and the fourth fixed part 123, respectively.

[0061] The second bow-shaped shackle 5 can be made of high-strength alloy material, and has strong load-bearing capacity and corrosion resistance. The second bow-shaped shackle 5 can serve as a connecting bridge between the beam body 1 and the second hanging belt 3. For example, each second hanging belt 3 can be connected with a different second bow-shaped shackle 5, that is, the second hanging belt 3 can be connected with the beam body 1 through the second bow-shaped shackle 5, so that each second hanging belt 3 can independently bear part of the weight of the photovoltaic support and uniformly transmit the force to the beam body 1 through the second bow-shaped shackle 5.

[0062] In an exemplary embodiment of the present disclosure, please continue to refer to Figure 4 As shown in the figure, the second bow-shaped shackle 5 can include a second fixed plate 51 and a second connecting plate 52 arranged on the second fixed plate 51. The second connecting plate 52 can be arranged perpendicularly to the second fixed plate 51. The second connecting plate 52 can be provided with a second connecting hole 521, which can penetrate the second connecting plate 52 along the thickness direction of the second connecting plate 52. The shape of the second connecting hole 521 can be circular, oval, polygonal, or irregular, and the shape of the second connecting hole 521 is not specially limited here.

[0063] In some embodiments of the present disclosure, the second fixed plates 51 of the four second bow-shaped shackles 5 can be fixed on the first fixed portion 112, the second fixed portion 113, the third fixed portion 122, and the fourth fixed portion 123, respectively, by welding or bolt connection, etc. Each second hanging belt 3 can be connected with the second connecting hole 521 of a different second bow-shaped shackle 5.

[0064] In an exemplary embodiment of the present disclosure, one end of each second hanging belt 3 can be connected with the second connecting hole 521 in the corresponding second bow-shaped shackle 5 through a special connecting device, so as to ensure firm connection and easy operation. For example, please continue to refer to Figure 2 As shown in the figure, the second hanging belt 3 can be connected with the second bow-shaped shackle 5 through the electric hoist 6. Specifically, the hoisting structure of the present disclosure can include a plurality of electric hoists 6, and each electric hoist 6 is connected to a different second bow-shaped shackle 5. For example, the electric hoist 6 can be hung on the second connecting hole 521 of the second bow-shaped shackle 5. That is, each electric hoist 6 can be connected with the second connecting hole 521 of the second bow-shaped shackle 5 through the lifting ring or special connecting plate on the top of the electric hoist 6. In order to ensure the stability of the connection between the second bow-shaped shackle 5 and the electric hoist 6, the connection part can be equipped with a locking screw or a locking washer to prevent loosening during long-term use and ensure the safety of hoisting operation.
