Detailed description of the specific embodiment

[0034] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not used to limit the present disclosure.

For example, referring to Figure 1 , Figure 1 the upper side in the drawing direction of Figure 1 is the "upper" side, the upper side in the drawing direction of

[0036] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and defined, the terms "arrangement", "connection", "attachment", and "installation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0037] As Figures 1 to 8 shown, the present disclosure provides a floating offshore photovoltaic platform, including a floating box support mechanism 10, a photovoltaic panel 20, and an anchoring device 30. The photovoltaic panel 20 is connected to the floating box support mechanism 10, and the floating box support mechanism 10 is used to support the photovoltaic panel 20 so that the photovoltaic panel 20 can absorb solar energy. The anchoring device 30 includes an anchoring end 31, a connecting member 32, and at least one mass damping component 33. The anchoring end 31 is used to connect to the seabed. The first end of the connecting member 32 is connected to the anchoring end 31, and the second end of the connecting member 32 is connected to the floating box support mechanism 10. The mass damping component 33 is detachably connected to the connecting member 32, and the mass damping component 33 is arranged to be able to adjust the draft depth of the floating box support mechanism 10.

[0038] Among them, laying the photovoltaic panel 20 on the floating box support mechanism 10 can float in the deep sea area. There is no occlusion in the deep sea, and the light intensity is high, which can better absorb solar energy and convert it into electric energy.

[0039] Among them, as Figure 1 shown, the floating box support mechanism 10 is connected to the seabed through the anchoring device 30. The anchoring end 31 of the anchoring device 30 is fixed to the seabed, and the connecting member 32 is connected to the floating box support mechanism 10, which can make the floating box support mechanism 10 move within a certain area, which is beneficial to restricting the movement range of the floating box support mechanism 10 and avoiding the floating box support mechanism 10 floating away randomly.

[0040] Among them, the mass damping component 33 is detachably connected to the connecting member 32, and such an arrangement facilitates adding or reducing the counterweight to the connecting member 32.

[0041] In the above solution, by arranging the photovoltaic panel 20 on the floating box support mechanism 10, the floating box support mechanism 10 can float on the sea surface, thereby providing buoyancy for the photovoltaic panel 20, enabling the photovoltaic panel 20 to also float on the sea surface and absorb solar energy. Through the cooperation of the connecting member 32 and the anchoring end 31 of the anchoring device 30, the floating box support mechanism 10 can float in the deep sea area. By detachably connecting the mass damping component 33 to the connecting member 32, the weight of the connecting member 32 can be increased or decreased, so that the pulling force of the connecting member 32 on the floating box support mechanism 10 changes, and then the draft depth of the floating box support mechanism 10 can be adjusted, enabling the floating box support mechanism 10 to maintain an appropriate draft depth, which can reduce the situation that the floating box support mechanism 10 swings up and down significantly under the action of loads such as wind and waves, improve the overall stability of the offshore photovoltaic platform, thereby ensuring the stability of the photovoltaic panel 20, and further ensuring the stability of the photovoltaic panel 20's absorption of solar energy. At the same time, the appropriate draft depth can also prevent the photovoltaic panel 20 from contacting seawater and ensure the service life of the photovoltaic panel 20.

[0042] To achieve the purpose of detachable connection between the connecting member 32 and the mass damping component 33, as an implementation manner of the connecting member 32, as Figure 4 shown, the connecting member 32 can be configured as an anchor chain. The anchor chain itself has a certain gravity and can play a certain buffering role for the external forces such as wind flow and sea waves acting on the floating box support mechanism 10 in the sea. Among them, the anchor chain includes a plurality of interconnected chain links 321, and the mass damping component 33 includes a weight block 331 and a mounting member 334. The mounting member 334 is connected to the weight block 331, and the mounting member 334 is detachably connected to one of the chain links 321.

[0043] Among them, the weight block 331 is used to provide a pulling force when the connecting member 32 is connected to the floating box support mechanism 10 on the sea surface, and the magnitude of this pulling force can be adjusted by the number of weight blocks 331 on the connecting member 32.

[0044] Among them, the mounting member 334 is used to detachably connect the mass damping component 33 to the weight block 331, that is, the mass damping component 33 is detachably connected to the weight block 331 through the mounting member 334.

[0045] Optionally, in an implementation manner of the present disclosure, as Figures 4 to 5 shown, a through hole 332 penetrating the weight block 331 is formed on the weight block 331, and the connecting member 32 passes through the through hole 332 so that the weight block 331 is sleeved on the connecting member 32. By setting it in this way, the weight block 331 can be conveniently moved on the connecting member 32 as needed, facilitating the adjustment of the position of the weight block 331 on the connecting member 32.

[0046] In addition, when the number of the mass damping components 33 is multiple, the distance between two adjacent weight blocks 331 can be conveniently adjusted by such a setting.

[0047] As an implementation manner of the mounting member 334, as Figures 4 to 5 shown, the mounting member 334 can be configured as a limiting rod, the limiting rod passes through one of the chain links 321, and a mounting hole 333 is formed on the weight block 331. The mounting hole 333 communicates with the through hole 332. The through hole 332 penetrates through the weight block 331 along the axial direction of the weight block 331, and the mounting hole 333 penetrates through the weight block 331 along the radial direction of the weight block 331, so that the mounting hole 333 and the through hole 332 are arranged at a right angle. The limiting rod passes through the mounting hole 333. At least two ends of the limiting rod have threads. The two ends of the limiting rod extend out of the weight block 331 and are threadedly connected with limiting nuts 335. Such a setting can realize the detachable connection between the weight block 331 and the connecting member 32, which is convenient for increasing or decreasing the counterweight on the connecting member 32. Wherein, the outer diameter of the limiting nut 335 is greater than the inner diameter of the chain link 321.

[0048] It can be understood that referring to Figure 4 , the above-mentioned axial direction is the horizontal direction of the weight block 331, and the radial direction is the vertical direction of the weight block 331.

[0049] As another implementation manner of the mounting member 334, as Figure 6 shown, the mounting member 334 can include a mounting plate 336 and a positioning rod 337. A mounting hole 333 is formed on the weight block 331. The mounting hole 333 communicates with the through hole 332. The through hole 332 of the weight block 331 penetrates through the weight block 331 along the axial direction of the weight block 331. The mounting hole 333 is arranged along the radial direction of the weight block 331. Wherein, a positioning groove 338 is arranged on the inner wall of the through hole 332. The positioning groove 338 communicates with the mounting hole 333 and the through hole 332. One end of the positioning rod 337 is fixedly connected to the end face of the mounting plate 336. The other end of the positioning rod 337 is inserted into the positioning groove 338 along the mounting hole 333. At this time, the lower end face of the mounting plate 336 is attached to the top face of the weight block 331, and then the mounting plate 336 is fixed on the weight block 331 by using screws 339 to realize the detachable connection between the weight block 331 and the connecting member 32.

[0050] Wherein, the diameters of the limiting rod and the positioning rod 337 should not exceed the inner diameter of a single chain link 321.

[0051] In order to achieve a wider adjustment range of the draft of the floating box support mechanism 10, as Figure 1As shown, optionally, in an embodiment of the present disclosure, the number of the mass damping components 33 may be multiple. The specific number of the mass damping components 33 may be determined according to the actual situation. The multiple mass damping components 33 are arranged at intervals along the length direction of the connecting member 32. The multiple mass damping components 33 can limit the connecting member 32 to be in an arc structure and limit the draft depth of the floating box support mechanism 10 to be half of the height of the floating box support mechanism 10.

[0052] Among them, since the multiple mass damping components 33 are arranged at intervals along the length direction of the connecting member 32, a downward force is generated at different positions of the connecting member 32, making the connecting member 32 in an arc structure. Thus, the connecting member 32 is in a non-tensioned state, which allows the floating box support mechanism 10 to generate an appropriate displacement in the horizontal direction under the action of loads such as wind and waves, avoiding damage caused by the violent pulling of the floating box support mechanism 10 due to the sudden action of loads such as wind and waves, and being beneficial to extending the service life of the floating offshore photovoltaic platform.

[0053] In addition, the greater the draft depth of the floating box support mechanism 10, the lower the center of gravity of the floating box support mechanism 10, the higher the stability, and the smaller the influence of the loads generated by the wind and waves on the floating box support mechanism 10. However, if the draft depth is too large, the photovoltaic panel 20 will easily come into contact with the sea level 1. And if the draft depth is too small, the stability of the floating box support mechanism 10 floating on the sea surface is relatively low. Under the influence of wind and waves, the swing amplitude of the floating box support mechanism 10 increases, resulting in violent pulling between the floating box support mechanism 10 and the connecting member 32 and causing damage. Therefore, the draft depth of the floating box support mechanism 10 can be adjusted to be half of the height of the floating box support mechanism 10 by increasing or decreasing the multiple mass damping components 33, which can not only make the floating box support mechanism 10 have a certain stability but also avoid the photovoltaic panel 20 contacting the sea level 1.

[0054] In some examples, as Figure 1 shown, the multiple mass damping components 33 are arranged at equal intervals along the length direction of the connecting member 32, so that the connecting member 32 can better maintain an arc structure.

[0055] It should be noted that the above-mentioned counterweight 331 can be adjusted in distance by sliding. The counterweight 331 is sleeved on the connecting member 32. Therefore, the distance between two adjacent counterweights 331 on the connecting member 32 can be adjusted.

[0056] Optionally, in an embodiment of the present disclosure, as Figures 2 to 3As shown in the figure, the floating box support mechanism 10 includes a truss body 11 and a plurality of floating boxes 12 arranged at intervals. A plurality of support units are provided on the top of the truss body 11, and the plurality of support units are arranged in an array. At least one photovoltaic panel 20 is laid on the top of each support unit. It should be understood that when the size of a photovoltaic panel 20 is large enough, then one photovoltaic panel 20 is laid on one support unit. When the size of a photovoltaic panel 20 is relatively small compared to the support unit, then multiple photovoltaic panels 20 can be laid on one support unit.

[0057] Make the top of each support unit flush with the top of the truss body 11, so that while the photovoltaic panel 20 on the top of the support unit is far from the sea level 1, it can also fully contact the sunlight.

[0058] Among them, connecting the plurality of floating boxes 12 to the truss body 11 can provide buoyancy for the photovoltaic panel 20.

[0059] Optionally, in an embodiment of the present disclosure, as Figures 2 to 3 shown, the truss body 11 includes a plurality of horizontally arranged truss groups and a plurality of vertically arranged truss groups. Each horizontally arranged truss group includes a plurality of horizontally arranged trusses 111 connected end to end. Each vertically arranged truss group includes a plurality of vertically arranged trusses 112 connected end to end. Each truss 111 of two adjacent horizontally arranged truss groups is arranged oppositely. Each truss 112 of two adjacent vertically arranged truss groups is arranged oppositely, so that the plurality of horizontally arranged truss groups and the plurality of vertically arranged truss groups together form a plurality of rectangular frames arranged in an array. Each truss 111 is connected to the adjacent truss 111 and truss 112 by at least one floating box 12. The support unit includes a plurality of parallel and spaced support rods 14 for supporting the photovoltaic panel 20. The spacing distance of the support rods 14 can be set according to the size of the photovoltaic panel 20. And the support rods 14 are located inside the rectangular frame and connected to the corresponding two trusses 111 or two trusses 112. In this regard, the present disclosure does not make a limitation. It should be noted that the floating boxes 12 on the periphery of the floating box support mechanism 10 can play a role in eliminating wave embankments.

[0060] Among them, as Figure 3As shown, both the transverse truss 111 and the longitudinal truss 112 include a truss upper chord 1111, a truss lower chord 1112, a truss diagonal 1113, and a truss vertical 1114, and together they form a double-layer truss system that can provide a structure for laying photovoltaic panels 20. Due to the loads generated by some natural actions at sea, these loads can damage the photovoltaic panels 20. Therefore, the photovoltaic panels 20 are laid on the top surface of the floating box support mechanism 10, and the floating box support mechanism 10 can provide sufficient space between the photovoltaic panels 20 and the sea level 1, thereby reducing the impact of loads such as sea waves on the photovoltaic panels 20 and being beneficial to extending the service life of the photovoltaic panels 20. It should be noted that all components of the truss body 11, as well as between the truss body 11 and the floating box 12, are rigidly connected, such as bolt connection or welding.

[0061] In addition, the rectangular frames composed of multiple transverse truss groups, longitudinal truss groups, and support rods 14 can be transported to the predetermined sea area of the project in batches and then spliced and assembled, which can effectively reduce the transportation and installation difficulties.

[0062] Optionally, in an embodiment of the present disclosure, as Figures 7 to 8 shown, the floating box 12 includes a body 121 and a pull ring 122. The body 121 is configured as a vertically arranged cuboid structure, and pull rings 122 are provided at the four corners of the bottom of the body 121. At least one pull ring 122 is connected to the second end of the connecting member 32. Among them, by arranging the pull rings 122 at the four corners of the bottom of the body 121, sufficient space can be provided for the connecting member 32 to pull the floating box support mechanism 10. When increasing or decreasing the mass damping component 33 on the connecting member 32, it is beneficial to control the draft depth of the entire photovoltaic platform and can better maintain at half of the height of the floating box support mechanism 10.

[0063] Among them, notches can be opened on the four side edges of the cuboid structure, so that the cross-sectional shape of the body 121 forms an octagonal structure. This notch can provide an installation position for the pull ring 122 and is also beneficial to reducing the occurrence of marine organisms attaching to the body 121.

[0064] Optionally, the number of the anchoring devices 30 can be multiple, and the multiple anchoring devices 30 are arranged around the circumferential direction of the floating box support mechanism 10, which is beneficial to improving the overall stability of the offshore photovoltaic platform.

[0065] In addition, in order to prevent the floating box support mechanism 10 and the anchoring devices 30 from being corroded by seawater, optionally, the outer walls of the floating box support mechanism 10 and the anchoring devices 30 are both coated with an anti-corrosion coating.

[0066] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0067] In addition, it should be noted that, in the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination manners.

[0068] Furthermore, any combination can be made among various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
