Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more specifically, to a water surface photovoltaic anchoring platform and a water surface photovoltaic system. Background Technology

[0002] Floating photovoltaic systems have become an important development direction in the new energy field due to their advantages such as not occupying valuable land resources, improving power generation efficiency through water cooling, and being able to be combined with aquaculture to achieve "fishery-solar complementarity". However, the stable operation of floating photovoltaic systems is highly dependent on the mooring system.

[0003] Traditional floating photovoltaic (PV) systems typically employ a dense network of peripheral anchor points. These anchor points are usually positioned around the perimeter of the PV array, extending to the water's edge or deeper areas for anchoring, ensuring overall resistance to lateral displacement. However, in some scenarios, limitations imposed by water boundaries, such as near-shore structures, ecologically sensitive areas, or waterways, prevent the ideal arrangement from being achieved, resulting in a lower system capacity. Furthermore, to balance the forces on the floating structure, a large number of anchor points are required, increasing construction complexity and potentially causing serious impacts on the aquatic ecosystem.

[0004] Therefore, how to improve the stability of photovoltaic arrays while simplifying the anchoring system has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a water surface photovoltaic anchoring platform that can improve the stability of the photovoltaic array while simplifying the anchoring system.

Detailed Implementation

[0028] The core of this application is to provide a water surface photovoltaic anchoring platform that can improve the stability of the photovoltaic array while simplifying the anchoring system.

[0029] Another core aspect of this application is to provide a water surface photovoltaic system with the aforementioned water surface photovoltaic anchoring platform.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] As the global energy structure accelerates its transition to clean energy, the photovoltaic industry has expanded from land to water. Floating photovoltaic systems, with their advantages of not occupying valuable land resources, improving power generation efficiency through water cooling, and achieving "fishery-solar complementarity" with aquaculture, have become an important development direction in the new energy field. However, the stable operation of floating photovoltaic systems is highly dependent on the mooring system. As the core structure connecting the photovoltaic float to the bottom of the water, the mooring system must not only withstand natural external forces such as wind, waves, currents, and water level fluctuations, but also adapt to the complex geological conditions of different water bodies, such as lakes, reservoirs, nearshore areas, and fishponds. The rationality of its design directly determines the safety, economy, and long-term reliability of the photovoltaic system.

[0032] Traditional floating photovoltaic (PV) mooring systems typically employ a dense array of peripheral anchor points. These anchor points are usually placed around the perimeter of the PV array and extend to the edge of the water or deeper areas for anchoring, ensuring overall resistance to lateral displacement. However, in some scenarios, limitations imposed by water boundaries, such as near-shore structures, ecologically sensitive areas, and waterways, may prevent the ideal arrangement and result in a lower system capacity. Furthermore, to balance the forces on the floating structure, a large number of anchor points are required, increasing construction complexity and potentially causing excessive disturbance to the benthic ecosystem. Especially in scenarios with high ecological protection requirements, such as reservoirs and natural lakes, the environmental impact of dense anchor points has become a key limiting factor for floating PV systems.

[0033] Therefore, such as Figure 1As shown in the illustration, this application discloses a surface photovoltaic anchoring platform 100, including a floating array 10 and anchoring components 20. By employing inclined anchoring components 20 with a certain angle, the anchoring force along the first and second directions can be achieved through a single anchor point, thereby reducing the number of anchor points, simplifying the anchoring system, and reducing the amount of anchoring construction. Simultaneously, by distributing the anchoring components 20 within the floating array 10, the installed capacity of the surface photovoltaic anchoring platform 100 can be increased, and the anchoring force can be made more uniform, effectively preventing internal bulging failure of the floating array 10 and improving the stability of the photovoltaic array.

[0034] The following will combine Figures 1 to 4 The water surface photovoltaic anchoring platform 100 disclosed in the embodiments of this application will be explained and described in detail.

[0035] like Figure 1 and Figure 2 As shown, the floating array 10 can support the photovoltaic module 200, enabling the photovoltaic module 200 to operate stably on the water surface. Among them, as... Figure 1 As shown, the floating array 10 can extend along a first direction, that is, the floating array 10 can be distributed along a north-south direction, and simultaneously the floating array 10 can extend along a second direction, that is, the floating array 10 can be distributed along an east-west direction. Furthermore, as... Figure 1 and Figure 2 As shown, multiple anchoring components 20 can be used, and each anchoring component 20 can be distributed dispersedly inside the floating array 10. That is, the anchoring components 20 can be arranged in an array inside the floating array 10, or the anchoring components 20 can be distributed irregularly at intervals inside the floating array 10. This can increase the installed capacity of the water surface photovoltaic anchoring platform 100, and the installed capacity of the water surface photovoltaic anchoring platform 100 increases with the depth of the water. At the same time, it can make the anchoring force more uniform, effectively avoid the internal bulging failure of the floating array 10, and improve the stability of the photovoltaic array. It should be noted that the inner side of the floating array 10 refers to the area enclosed by the outermost edge of the floating array 10.

[0036] like Figure 1 and Figure 2As shown, the anchoring assembly 20 may include a traction member 21 and an anchor member 22. The anchor member 22 may be located on the seabed, and one end of the traction member 21 may be connected to the anchor member 22, while the other end of the traction member 21 may be connected to the floating array 10. This allows the anchor member 22 to pull the floating array 10 via the traction member 21, thereby limiting the drifting and other movements of the floating array 10. Furthermore, the traction member 21 may be tilted simultaneously towards both the first and second directions, meaning the force applied to the anchoring assembly 20 may have an angle with both the north-south and east-west directions. This allows the anchoring assembly 20 to simultaneously limit the movement of the floating array 10 in both the east-west and north-south directions, thus achieving anchoring force along both the first and second directions through a single anchor point. This reduces the number of anchor points, simplifies the anchoring system, and reduces the amount of anchoring work required. It should be noted that the anchor 22 can be a heavy object with a certain weight, such as a concrete block or a steel block, and the traction component 21 can be an anchor chain or an anchor rope, so as to achieve the pulling effect of the traction component 21 on the floating array 10 and prevent the floating array 10 from drifting or moving.

[0037] In some embodiments, such as Figure 1 As shown, the anchoring components 20 can be arranged opposite each other along the second direction of the floating array 10, i.e., the east-west direction. At the same time, the anchoring components 20 can be staggered or symmetrically distributed along the first direction of the floating array 10, i.e., the north-south direction, to ensure that the anchoring force of the floating array 10 is more uniform and to effectively prevent the risk of failure of the floating array 10 due to internal bulging.

[0038] In some embodiments, such as Figure 2 As shown, the floating array 10 may include multiple floats 11, which can be arranged in an array. Multiple support rods can be connected between adjacent rows of floats 11, allowing photovoltaic modules 200 to be installed on adjacent support rods. This provides buoyancy support for the photovoltaic modules 200, ensuring stable operation of the photovoltaic modules 200 on the water surface. A traction member 21 can be connected to the floats 11, allowing the anchor 22 to pull on the floats 11 of the floating array 10 via the traction member 21. This restricts the drifting and other movements of the floating array 10, ensuring the stability of the water surface photovoltaic system.

[0039] In some embodiments, the side of the float 11 may be provided with an ear hole, and the traction member 21 may be connected to the ear hole of the float 11 through a fastener to achieve a reliable connection between the traction member 21 and the float 11. At the same time, the anchor 22 may be provided with a lifting lug that can be connected to the traction member 21, so that the traction member 21 may be connected to the lifting lug of the anchor 22 through a fastener. Thus, the anchor 22 may be able to pull the float 11 of the floating array 10 through the traction member 21 to limit the drift and other movements of the floating array 10 and ensure the stability of the water surface photovoltaic system.

[0040] In some embodiments, in order to improve the anchoring strength of the anchoring component 20, such as Figure 2 and Figure 3 As shown, the anchoring assembly 20 may also include a connector 23. The connector 23 may be made of a metal material with a certain strength, such as steel. The connector 23 is detachably connected to the float 11, and the traction member 21 is connected to the connector 23 to improve the connection strength between the traction member 21 and the float 11 and prevent the float 11 from deforming and breaking when subjected to a large tensile force.

[0041] In some embodiments, such as Figure 3 As shown, the connector 23 may include a pair of first connecting rods 231 and second connecting rods 232, and the two second connecting rods 232 may be welded to both ends of the first connecting rod 231 to form a stable truss structure. The traction member 21 may be connected to the first connecting rod 231, and the second connecting rods 232 may be connected to the connection positions of two adjacent floats 11 using bolts or other fasteners to achieve a connection and fixation between the connector 23 and the floats 11. Preferably, two adjacent floats 11 may share a single fastener with the second connecting rod 232; that is, the connection holes on the second connecting rod 232 may correspond to the connection holes between the two adjacent floats 11. Thus, bolts or other fasteners may be passed sequentially through the connection holes on the second connecting rod 232 and the connection holes between the two adjacent floats 11 to achieve a connection and fixation between the second connecting rod 232 and the floats 11, thereby reducing the number of fasteners and saving costs.

[0042] In some embodiments, such as Figure 3 As shown, in order to improve the overall strength of the connector 23, the connector 23 may also include at least one reinforcing rod 233. That is, one, two or more reinforcing rods 233 may be used, and the reinforcing rods 233 may be connected between two first connecting rods 231 by welding, thereby improving the overall strength and stability of the connector 23.

[0043] In some embodiments, such as Figure 3As shown, both the first connecting rod 231 and the second connecting rod 232 can be made of channel steel, and the slots of the two first connecting rods 231 can be arranged opposite each other, so that the reinforcing rod 233 can be welded to the side wall of the first connecting rod 231, thereby increasing the welding area between the reinforcing rod 233 and the first connecting rod 231 and ensuring the connection strength between the reinforcing rod 233 and the first connecting rod 231. Meanwhile, the slot of the second connecting rod 232 can be oriented upwards, so that bolts and other fasteners can be passed sequentially through the connecting holes on the second connecting rod 232 and the connecting holes between two adjacent floats 11, thereby achieving the connection and fixation between the second connecting rod 232 and the float 11. It should be noted that the reinforcing rod 233 can be made of channel steel, L-shaped steel, etc., and this is not limited here.

[0044] In some embodiments, such as Figure 3 As shown, in order to improve the connection strength between the first connecting rod 231 and the second connecting rod 232, the local position of the second connecting rod 232 can be reinforced. For example, at the connection position between the second connecting rod 232 and the first connecting rod 231, the side wall of the second connecting rod 232 can be raised to ensure that there is a larger welding area between the second connecting rod 232 and the first connecting rod 231, thereby ensuring the reliability of the connection between the first connecting rod 231 and the second connecting rod 232.

[0045] In some embodiments, such as Figure 3 As shown, the connector 23 may further include a stiffening rib 234, which may have a first connecting side and a second connecting side. The first connecting side and the second connecting side may be arranged at an angle, for example, the first connecting side may be perpendicular to the second connecting side, i.e., the angle between the first connecting side and the second connecting side may be 90°. The first connecting side may be connected to the first connecting rod 231 by welding, and the second connecting side may be connected to the second connecting rod 232 by welding. Thus, the stiffening rib 234 can improve the connection strength and stability between the first connecting rod 231 and the second connecting rod 232. The stiffening rib 234 may be connected to the two side walls of the first connecting rod 231 and the side wall of the second connecting rod 232 respectively, thereby increasing the welding area between the first connecting rod 231 and the second connecting rod 232 and ensuring the reliability of the connection between the first connecting rod 231 and the second connecting rod 232.

[0046] In some embodiments, such as Figure 3As shown, the first connecting rod 231 may be provided with a connecting portion 2311 that can be connected to the traction member 21. The connecting portion 2311 may be symmetrically arranged on the bottom wall of the two first connecting rods 231, so as to be connected to the anchors 22 on both sides of the float 11 respectively via the traction member 21. Simultaneously, the connecting portion 2311 may have a connecting hole 2312 for connecting the traction member 21, thereby allowing the traction member 21 to be connected to the connecting hole 2312 of the connecting portion 2311 via a fastener, thus achieving a reliable connection between the traction member 21 and the connecting member 23.

[0047] In some embodiments, such as Figure 4 As shown, the connecting part 2311 may include a lug 2313 and a stud 2314 connected to the lug 2313. A connecting hole 2312 may be located on the lug 2313, and the lug 2313 may be threadedly connected to the first connecting rod 231 via the stud 2314 to improve the ease of assembly and disassembly of the anchoring assembly 20. Simultaneously, the traction member 21 may be connected to the connecting hole 2312 of the lug 2313 via a fastener, thereby achieving a reliable connection between the traction member 21 and the connecting member 23.

[0048] The water surface photovoltaic anchoring platform 100 disclosed in this application embodiment disperses multiple anchoring components 20 inside the floating array 10 and places the anchors 22 of the anchoring components 20 on the bottom of the water. At the same time, the anchors 22 are connected to the floating array 10 through the traction member 21, and the traction member 21 can be tilted along the first direction and the second direction respectively.

[0049] The surface photovoltaic anchoring platform 100 disclosed in this application adopts a inclined anchoring component 20 with a certain angle, which can realize the anchoring force along the first direction and the second direction through a single anchor point, thereby reducing the number of anchor points, simplifying the anchoring system, and reducing the amount of anchoring construction. At the same time, by distributing the anchoring components 20 inside the floating array 10, the installed capacity of the surface photovoltaic anchoring platform 100 can be increased, and the anchoring force can be made more uniform, which can effectively avoid the internal bulging failure of the floating array 10 and improve the stability of the photovoltaic array.

Therefore, this surface photovoltaic system has all the technical effects of the above-mentioned surface photovoltaic anchoring platform 100, which will not be repeated here. The photovoltaic module 200 can be installed on the surface photovoltaic anchoring platform 100 to ensure that the photovoltaic module 200 can operate stably on the water surface.
