Description

Technical Field

[0001] This invention relates to the field of offshore photovoltaic power generation, and specifically to an offshore floating photovoltaic support platform system. Background Technology

[0002] As the global energy structure moves towards carbon neutrality, photovoltaic (PV) power generation, as a green, clean, and renewable energy source, has achieved remarkable development in recent years. The ocean, with its vast water area and distance from residential areas, offers the potential to improve the comprehensive utilization efficiency of marine space by constructing PV projects there. Compared to land, the ocean's expansive waters allow for the layout of PV arrays without being limited by regional shape, enabling the more systematic placement of large-scale PV arrays and creating favorable conditions for the comprehensive development of the offshore PV industry.

[0003] However, offshore floating photovoltaic (PV) projects face multiple challenges in their development towards the sea. The PV array structure is severely affected by wind, wave, and current loads, exhibiting violent dynamic responses. The loads on the supporting platform, mooring system, and connectors are complex and variable, making them susceptible to severe damage. Currently, offshore floating PV systems in inland waters utilize modular arrays with high-density polyethylene (HDPE) pontoons and support brackets. However, in the complex marine environment, the multi-degree-of-freedom movements between modules can be extremely violent, making it difficult for these inland water structures to withstand significant environmental loads. When using semi-submersible large modular structures, high reliability is required at the connections, and connector failure has a cascading effect; a connection failure at one point could trigger a complete platform failure.

[0004] In summary, the current floating photovoltaic (PV) carrier platforms have multiple carrier modules that are relatively dispersed, and the connection stability between adjacent carrier modules is poor, which makes the overall stability and connection security of the floating PV carrier platforms worrying.

[0018] (I) This invention provides a floating photovoltaic (PV) support platform system for offshore use, comprising a central support module, a first peripheral support module, a second peripheral support module, a third peripheral support module, and a fourth peripheral support module. The first, second, third, and fourth peripheral support modules serve as peripheral modules of the central support module, arranged around it.

[0019] (II) This invention provides a floating photovoltaic support platform system for marine applications. The connection seams between the two outer support modules and between the outer and central support modules are not on the same straight line, effectively avoiding the straight "through seams" found in traditional checkerboard-style distribution arrays. The overall support platform exhibits better overall connectivity, reducing the violent relative pitching response of the support modules on both sides of the platform, and significantly lowering the risk of instantaneous damage and fatigue failure of the connectors. The floating photovoltaic support platform system disclosed in this invention overcomes the shortcomings of existing floating photovoltaic support platforms in terms of hydrodynamic performance. It particularly focuses on reducing the overall response of multi-buoy platforms and the relative motion response between modules while minimizing costs, optimizing the stress characteristics of platform mooring and connectors, thereby ensuring the overall safety of the platform and the durability of platform connectors.

[0028] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0029] In traditional checkerboard-like layouts, such as those in patent publications CN219893207U and CN117302443A, some connecting seams between multiple load-bearing platforms can be connected into straight lines that run through the structure, known as straight "through seams." The platforms are divided into several regions by these through seams. When the wave propagation direction is perpendicular to the through seam, modules within a single region exhibit better overall connectivity, while modules on either side of the through seam are prone to violent relative pitching motions, significantly increasing the risk of instantaneous damage and fatigue failure of the connectors. For example, ideally, considering a regular wave incident at 0° on the module array, only the connectors perpendicular to the wave propagation direction are subjected to force, resulting in severe uneven stress distribution.

[0030] This invention discloses a floating photovoltaic (PV) platform system for offshore use. A first peripheral support module 11, a second peripheral support module 12, a third peripheral support module 13, and a fourth peripheral support module 14 serve as peripheral modules around a central support module 10. Adjacent support modules are connected by at least one connector, forming an integrated support platform. This connects adjacent single modules into a multi-module PV platform. Under wave action, each module undergoes translational and rotational movements in three directions, resulting in relative displacement between modules. The connecting components bear the connecting force, improving the connection stability between adjacent support modules. This solves the problem of currently available floating PV platforms where multiple support modules are scattered and the connection stability between adjacent support modules is poor.

[0031] Example 1: A floating photovoltaic support platform system at sea

[0032] Example 1 provides a floating photovoltaic support platform system for the sea. Its structure will be described in detail below with reference to the accompanying drawings.

[0033] refer to Figure 1 The floating photovoltaic support platform system includes a central support module 10, a first peripheral support module 11, a second peripheral support module 12, a third peripheral support module 13, and a fourth peripheral support module 14.

[0034] The first peripheral support module 11, the second peripheral support module 12, the third peripheral support module 13, and the fourth peripheral support module 14 serve as peripheral modules of the central support module 10. They are arranged around the central support module 10, and adjacent support modules are connected by at least one connector to form an overall support platform. Figure 2 As shown.

[0035] Among them, the overall support platform can be connected into a large-scale floating photovoltaic system at sea, which helps to limit the excessive distance between support modules, shearing motion and relative rotation of the connection seams perpendicular to the support modules, improves the connection stability between adjacent support modules, and solves the problem that the multiple support modules of the current floating photovoltaic support platform at sea are relatively dispersed and the connection stability between adjacent support modules is poor.

[0036] In one specific implementation, the first peripheral support module 11, the second peripheral support module 12, the third peripheral support module 13, the fourth peripheral support module 14 and the central support module 10 each include a support plate 101 for installing photovoltaic panels and electrical equipment. Each support plate 101 has at least one float 102 on its bottom surface to provide buoyancy to the support plate 101 above it.

[0037] The support plate 101 of the first peripheral support module 11, the second peripheral support module 12, the third peripheral support module 13, and the fourth peripheral support module 14 is pentagonal, and two sides of the pentagon are perpendicular to each other as the exposed outer side.

[0038] The support plate 101 of the central bearing module 10 is rhomboid. The remaining three sides of the first peripheral bearing module 11, the second peripheral bearing module 12, the third peripheral bearing module 13, and the fourth peripheral bearing module 14 are hidden inside the overall bearing platform. They are respectively opposite to one side of the inner side of the peripheral bearing module adjacent to both ends and one side of the support plate 101 of the central bearing module 10.

[0039] The connection seams between the two outer bearing modules and between the outer bearing module and the central bearing module 10 form two bends, resulting in three connection seams that do not form straight "through seams" in the checkerboard distribution array. The overall bearing platform has better overall connection integrity, the probability of violent relative swaying motion between adjacent bearing modules inside the overall bearing platform is reduced, and the risk of instantaneous damage and fatigue damage to the connector is greatly reduced.

[0040] In one specific implementation, an intermediate connecting seam is formed between each pair of adjacent bearing modules in the first peripheral bearing module 11, the second peripheral bearing module 12, the third peripheral bearing module 13, and the fourth peripheral bearing module 14, for a total of four intermediate connecting seams.

[0041] The central bearing module 10 forms an internal connection seam with the first peripheral bearing module 11, the second peripheral bearing module 12, the third peripheral bearing module 13, and the fourth peripheral bearing module 14, forming a total of four internal connection seams.

[0042] Each of the four intermediate connecting seams and the four internal connecting seams is provided with a connector to connect adjacent load-bearing modules together.

[0043] To improve the stability of the internal connections of the overall support platform and avoid the strong relative pitch response between modules caused by the wave propagation direction being perpendicular to the straight seam in a checkerboard array, preferably, the support plate 101 of the central support module 10 is square, and the angle between the intermediate connecting seam and its adjacent internal connecting seam is 45 degrees.

[0044] More specifically, the connectors include a first connector 21, a second connector 22, a third connector 23, a fourth connector 24, a fifth connector 25, a sixth connector 26, a seventh connector 27, and an eighth connector 28.

[0045] A first connector 21 is provided in the intermediate connecting seam between the first peripheral support module 11 and the second peripheral support module 12. The first connector 21 connects the support plate 101 of the first peripheral support module 11 and the support plate 101 of the second peripheral support module 12 together.

[0046] A second connector 22 is provided in the intermediate connecting seam between the first peripheral support module 11 and the fourth peripheral support module 14. The second connector 22 connects the support plate 101 of the first peripheral support module 11 and the support plate 101 of the fourth peripheral support module 14 together.

[0047] A third connector 23 is provided in the internal connection seam between the first peripheral support module 11 and the central support module 10. The third connector 23 connects the support plate 101 of the first peripheral support module 11 and the support plate 101 of the central support module 10 together.

[0048] A fourth connector 24 is provided in the intermediate connecting seam between the second peripheral support module 12 and the third peripheral support module 13. The fourth connector 24 connects the support plate 101 of the second peripheral support module 12 and the support plate 101 of the third peripheral support module 13 together.

[0049] A fifth connector 25 is provided in the internal connection seam between the second peripheral support module 12 and the central support module 10. The fifth connector 25 connects the support plate 101 of the second peripheral support module 12 and the support plate 101 of the central support module 10 together.

[0050] A sixth connector 26 is provided in the intermediate connecting seam between the third peripheral support module 13 and the fourth peripheral support module 14. The sixth connector 26 connects the support plate 101 of the third peripheral support module 13 and the support plate 101 of the fourth peripheral support module 14 together.

[0051] A seventh connector 27 is provided in the internal connection seam between the third peripheral support module 13 and the central support module 10. The seventh connector 27 connects the support plate 101 of the third peripheral support module 13 and the support plate 101 of the central support module 10 together.

[0052] An eighth connector 28 is provided in the internal connection seam between the fourth peripheral support module 14 and the central support module 10. The eighth connector 28 connects the support plate 101 of the fourth peripheral support module 14 and the support plate 101 of the central support module 10 together.

[0053] Continue to refer to Figure 2Three floats 102 are arranged at the lower part of the support plate 101 of the first peripheral support module 11, the second peripheral support module 12, the third peripheral support module 13, and the fourth peripheral support module 14. The three floats 102 are distributed at the three corners of the support plate 101 of the first peripheral support module 11, the second peripheral support module 12, the third peripheral support module 13, and the fourth peripheral support module 14 in a triangular distribution. Adjacent floats 102 are connected by a horizontal bar 103.

[0054] The lower part of the support plate 101 of the central bearing module 10 is provided with four pontoons 102, and the four pontoons 102 are respectively located at the four corners of the bottom surface of the support plate 101 of the central bearing module 10. The adjacent pontoons 102 are connected by a horizontal bar 103.

[0055] Therefore, the overall support platform consists of a total of sixteen pontoons 102 and sixteen horizontal bars 103.

[0056] As one specific implementation method, refer to Figure 3 Each connector includes two fasteners 31 and a waterproof and corrosion-resistant flexible tube. The two fasteners 31 are located at both ends of the connection seam between the support plates 101 of two adjacent load-bearing modules. The waterproof and corrosion-resistant flexible tube is sleeved on the two fasteners 31 and wraps around the two fasteners 31.

[0057] The connection seam between the support plates 101 of two adjacent load modules is sealed with a waterproof and corrosion-resistant soft tubing. This isolates the connector from the external environment, improving the durability of related components, and provides convenience and safety for the installation and maintenance of photovoltaic panels.

[0058] More specifically, the two ends of the fixing member 31 are respectively fixed to the sides of the support plates 101 of two adjacent carrier modules. Several cables 32 are threaded through the fixing member 31. Cable loops are respectively provided in the support plates 101 of two adjacent carrier modules. The two ends of each cable 32 extend into the support plates 101 of two adjacent carrier modules and are hung on their respective cable loops.

[0059] To effectively prevent collisions between modules, the fixing component 31 is specifically a polyurethane block. This polyurethane block is an elastic body. When relative yaw motion occurs between the modules, the elastic block bends, with one side under compression and the other under tension on its neutral axis. Based on the material properties, it can provide a restoring bending moment to limit this movement. The connector is compressed by the polyurethane material itself, while the tension is shared by the polyurethane material and the cable. The cable acts as a limiter to prevent the polyurethane block from being pulled apart.

[0060] To prevent the cable 32 from abrading the fixing member 31, a flexible tube is provided on the outside of the cable 32, and the cable 32 and the fixing member 31 can be separated by the flexible tube.

[0061] To facilitate control of the overall support platform, a corner mooring 41 is attached to the buoy 102 near the corner of the first peripheral support module 11, the second peripheral support module 12, the third peripheral support module 13, and the fourth peripheral support module 14, respectively, with the bottom end of the corner mooring 41 fixed to the seabed.

[0062] Continue to refer to Figure 2 The adjacent buoys 102 of the bearing module are respectively tied with mooring lines, and the adjacent mooring lines are combined to form an intermediate mooring 42, the bottom end of which is fixed to the seabed.

[0063] Specifically, adjacent buoys 102 between the first peripheral support module 11 and the second peripheral support module 12 form an intermediate mooring 42, adjacent buoys 102 between the second peripheral support module 12 and the third peripheral support module 13 form an intermediate mooring 42, adjacent buoys 102 between the third peripheral support module 13 and the fourth peripheral support module 14 form an intermediate mooring 42, and adjacent buoys 102 between the fourth peripheral support module 14 and the first peripheral support module 11 form an intermediate mooring 42.

[0064] Specifically, both the apex mooring 41 and the intermediate mooring 42 are constructed using steel cables.

[0065] Specifically, each corner buoy 102 is connected to an anchor chain, and two adjacent side buoys 102 share an anchor chain through a "Y"-shaped connection, for a total of eight anchor chains, which are evenly located at the corners and midpoints of the overall deck.

[0066] Compared to the usual four-anchor chain system at the apex, the anchor chain system in this invention achieves eight-directional segmentation of the horizontal plane, improving the anisotropy of the mooring system to wave direction. That is, under any wave direction, the eight anchor chains can be subjected to force more evenly, and the severe uneven force distribution phenomenon that occurs when the four-anchor chain system is obliquely incident will not occur.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
