Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation technology, and in particular to a flexible photovoltaic support assembly and a photovoltaic power station. Background Art

[0002] Current photovoltaic support components generally use east-west steel strands instead of purlins for fixed brackets, with photovoltaic components arranged in the north-south direction and support cables arranged in the east-west direction. Due to the overall structural instability and weak support capacity, the laying distance of such photovoltaic support components is limited, and strong anchoring measures are generally required at the east-west ends. However, end anchoring measures are costly and difficult to construct. In addition, the laying range of such flexible brackets is limited, and the application scenarios are demanding. Figure 1 In the scenario shown, due to the existence of main roads, high-voltage lines, railways, etc., which do not allow the photovoltaic support components to be installed across them, the photovoltaic support components need to be disconnected from the middle multiple times and anchored at the corresponding disconnection positions, which increases costs.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] In order to optimize the supporting capacity of flexible photovoltaic support components, improve the overall structural stability, expand the installation range of photovoltaic components and reduce costs while reducing the requirements for application scenarios, this application proposes a flexible photovoltaic support component and a photovoltaic power station.

[0043] Reference Figures 2 to 9 The flexible photovoltaic support assembly includes multiple brackets, multiple groups of support cable groups 200 are provided on the multiple brackets, and at least one truss support member 300 is provided in the middle of the multiple groups of support cable groups 200. When multiple truss support members 300 are provided, the multiple truss support members 300 are arranged at intervals along the first direction, and the distance between any two adjacent truss support members is the same or different.

[0044] Understandably, Figure 2 The direction indicated by arrow a is the first direction, and the direction indicated by arrow b is the second direction. The first direction and the second direction are intersecting. Specifically, the first direction and the second direction can be set to be perpendicular to each other according to the requirements of the actual application scenario, and in applications such as Figure 1 When setting a scene, set the first direction to correspond to the north-south direction and the second direction to correspond to the east-west direction.

[0045] The support cable groups 200 extend along a first direction to enable long-distance paving. The truss supports 300, acting as a supporting structure, distribute and transfer loads, reducing stress concentration within the support cable groups 200. This optimizes the support capacity of the flexible photovoltaic support assembly and enhances the rigidity and stability of the overall structure. By providing support for the cable groups 200 through the truss supports 300, the flexible photovoltaic support assembly's span can be expanded, increasing the installation rate of photovoltaic modules, further increasing power generation, and broadening the application scenarios of the flexible photovoltaic support assembly.

[0046] In the embodiment of the present application, each supporting cable group 200 includes a load-bearing cable 220 and at least two component cables 210 that are spaced apart and used to support the photovoltaic component 500 .

[0047] At least two spaced-apart component cables 210 are parallel to each other, or at least two spaced-apart component cables 210 are angled to each other. As a supporting structure, the truss support member 300 not only disperses and transfers loads, reducing stress concentration in the support cable assembly 200, but also optimizes the supporting capacity of the flexible photovoltaic support assembly and improves the rigidity and stability of the overall structure.

[0048] The load-bearing cable 220 is disposed below two adjacent component cables 210 to shape the component cables 210 and the load-bearing cable 220. The truss support member 300 is disposed between the component cables 210 and the load-bearing cable 220.

[0049] The upper and lower layers of the component cables 210 and the load-bearing cables 220 can share the weight of the installed photovoltaic panels 500, improving load-bearing capacity. By placing truss supports 300 in the middle of the support cable assembly 200, the cross-section of the truss formed by the component cables 210 and the load-bearing cables 220 is expanded outward. This not only increases the torsional resistance of the overall structure and improves its stability, but also reduces the use of material and anchoring structure for the support cable assembly 200, effectively reducing costs.

[0050] The support cable assembly 200 is arranged to extend along a first direction, with a row of photovoltaic modules installed on the support cable assembly 200 along the first direction as a horizontal row. Each flexible photovoltaic support assembly is used to install multiple rows of photovoltaic modules, that is, each flexible photovoltaic support assembly can be used to install two, three, four, or other multiple rows of photovoltaic modules. Optionally, in an embodiment of the present application, in order to improve wind resistance and reliability, meet different discharge requirements, and adapt to different site boundary conditions such as locally narrow and long protruding boundaries, three horizontal rows of photovoltaic modules are used as the minimum basic unit, and the flexible photovoltaic support assembly is used to install at least three horizontal rows of photovoltaic modules. Photovoltaic modules 500 in different horizontal rows do not need to be interconnected, so as to extend the span and increase the laying rate when applied to scenes with special locally protruding boundaries.

[0051] Reference Figure 5 、 Figure 6 In one embodiment, the truss support 300 includes a support frame 310 having a rectangular shape.

[0052] The support frame is rectangular, specifically, the outer shape of the support frame 310 is designed to be a closed rectangle, making the cross-section of the truss support member 300 rectangular. Unlike non-closed support structures, the closed nature of the rectangle can better resist external loads and reduce the risk of structural deformation and damage. The closed support structure has good lateral resistance due to its large lateral stiffness. It can also effectively resist lateral loads and disperse and transfer loads through various parts of the support frame 310. Unlike trapezoids, other regular or irregular shapes, and their combinations, setting the support frame 310 to be rectangular can make the force distribution more uniform, ensure the strength and stability of the structure, and because the rectangular geometry is relatively simple, it is also easy to process, install, and maintain.

[0053] Specifically, the support frame 310 has an upper chord 311 and a lower chord 312 that are relatively arranged. The upper chord 311 has a plurality of upper support nodes 3111 connected to the component cables 210 , and the lower chord 312 has a plurality of lower support nodes 3121 connected to the load-bearing cables 220 .

[0054] The arrangement of the upper chord 311 and lower chord 312 facilitates load transfer and reduces load-induced structural deformation and vibration, ensuring the stability of the truss support 300 when subjected to vertical loads and wind loads. Load distribution through multiple upper support nodes 3111 on the upper chord 311 and multiple lower support nodes 3121 on the lower chord 312 reduces stress concentration in the truss support 300 and prevents structural deformation caused by local overload. Furthermore, the connection of the component cables 210 through multiple upper support nodes 3111 and the connection of the load-bearing cables 220 through multiple lower support nodes 3121 prevents instability and effectively improves the stability, safety, and durability of the connected structure.

[0055] Reference Figure 5 、 Figure 6 In one embodiment, the truss support member 300 also includes a connecting member 320 arranged in the middle of the support frame 310, the connecting member 320 has a first end and a second end arranged opposite to each other, the first end of the connecting member 320 is connected to the upper support node 3111; the second end of the connecting member 320 is connected to the lower support node 3121.

[0056] As can be understood, there are multiple upper support nodes 3111 provided on the upper chord 311 and multiple lower support nodes 3121 provided on the lower chord 312. The first end of the connector 320 is connected to at least some of the multiple upper support nodes 3111, and the second end of the connector 320 is connected to at least some of the multiple lower support nodes 3121. The connector 320 is provided in the middle of the support frame 310. The connection between the connector 320 and the upper and lower support nodes 3111 and 3121 further improves the stability of the structure and optimizes the overall structural rigidity, making the truss support member 300 more robust to handle greater loads and complex stress conditions, while reducing structural deformation and vibration caused by loads.

[0057] Support frame 310 has a first corner portion 331 and a second corner portion 332, which are positioned opposite each other along the second direction. To further ensure structural stability and optimize force distribution, the first of the multiple lower support nodes is located at first corner portion 331, and the last of the multiple lower support nodes is located at second corner portion 332. Placing support nodes at the corners of support frame 310 ensures that when loaded, force is more effectively transferred to the support nodes, reducing the problem of excessive localized force and improving the stability and durability of the overall structure.

[0058] It can be understood that the truss support member 300 has a rectangular support frame 310. In the assembled state, the height of the rectangle corresponds to the vertical direction, and the length of the rectangle is parallel to the second direction. The bending angle of the support frame 310 is used as the corner of the support frame 310. The support frame 310 is specifically provided with four corners, and its two corners arranged on the lower chord along the second direction are respectively used as the first corner 331 and the second corner 332. The first and the last of the multiple lower support nodes are respectively arranged at the first corner 331 and the second corner 332.

[0059] Reference Figure 5 、 Figure 6 In one embodiment, the truss support member 300 has at least one triangular support region, with at least one upper support node connected to at least one lower support node via connectors 320 to form a triangular support region connected to the support frame. This distributes loads and reduces stress concentration through the support nodes in the triangular support region, improving structural stability and connection strength, and extending service life.

[0060] Optionally, when the truss support member 300 has multiple triangular support areas, this can be achieved in the following manner: the connecting member 320 includes a first connecting rod 321 and a second connecting rod 322, which are alternately arranged along the second direction in the middle of the support frame 310. This arrangement can be used to ensure structural stability and uniform load distribution. When the left and right directions of the truss support 300 correspond to the second direction, the first end of the first link 321 of the first connecting member 320 is connected to the upper support node in the middle of the upper chord, and the second end is connected to the first lower support node (i.e., the first corner 331), which is used to enclose a triangular support area at the upper left corner of the truss support 300; the first end of the second link 322 of the last connecting member 320 is connected to the upper support node in the middle of the upper chord, and the second end is connected to the last lower support node (i.e., the second corner 332), which is used to enclose a triangular support area at the upper right corner of the truss support 300; the second end of the first link 321 of the next connecting member 320 and the second end of the second link 322 of the previous connecting member 320 are connected to the same lower support node 3121, which are used to enclose a triangular support area with the upper chord.

[0061] It should be noted that the plurality of connectors 320 are sequentially arranged along the second direction in the middle portion of the support frame 310. Regardless of the number of connectors 320, the two connectors 320 located at the two ends serve as the first connector 320 and the last connector 320, respectively. The second end of the first link 321 of the first connector 320 is connected to the first lower support node (i.e., the first corner 331), and the second end of the second link 322 of the last connector 320 is connected to the last lower support node (i.e., the second corner 332). The second ends of the other first links 321 and the second ends of the other second links 322 located in the middle portion are connected to other positions between the first corner 331 and the second corner 332 of the lower chord 312. When the first and second links 321, 322 of the connector 320 are arranged in an "eight" shape, the second ends of the other first links 321 and second links 322 located in the middle are connected to the other lower support nodes 3121 between the first corner portion 331 and the second corner portion 332, such that the second end of the first link 321 of the next connector 320 and the second end of the second link 322 of the previous connector 320 are connected to the same lower support node 3121. This is used to form a triangular support area by enclosing the first link 321 of the next connector, the second link 322 of the previous connector, and the upper chord of the support frame 310. Multiple triangular support areas can be arranged in a connected or spaced arrangement: when connected, the first end of the first link 321 and the first end of the second link 322 of the same connector 320 are connected to the same support node; when spaced, the first end of the first link 321 and the first end of the second link 322 of the same connector 320 are connected to two adjacent support nodes.

[0062] The support frame 310 and triangular support area function as a closed structure, enhancing the structure's resistance to reversal in strong winds. The intersections of the steel strands (assembly cables 210 and load-bearing cables 220) and the truss support members 300 are supported by connectors (first and second links 321 and 322). This ensures that forces are applied to the support nodes of the triangular support area, reducing internal forces within the connectors and stress concentration. Furthermore, the dimensions of the first and second links 321 and 322 can be reduced, conserving material and simplifying the structure.

[0063] Optionally, the support trusses are provided with snap rings, locking pieces, clamps, etc. at positions corresponding to the upper support nodes 3111 and the lower support nodes 3121 for installing the component cables 210 and the load-bearing cables 220 .

[0064] Reference Figure 7 In the embodiment of the present application, the outermost component cable 210 and the outermost load-bearing cable 220 are located in the same vertical direction to ensure the stability and symmetry of the overall structure and reduce lateral deformation. Taking the installation of three horizontal rows of photovoltaic modules as an example, it can be seen from the aforementioned embodiment that there are multiple upper support nodes 3111 located on the upper chord, two of which are located at two corners of the upper chord, and the first end of the first connecting rod 321 and the first end of the second connecting rod 322 are respectively connected to the upper support node 3111 of the upper chord 311; there are multiple lower support nodes 3121 located on the lower chord, two of which are located at two corners of the lower chord, and the second end of the first connecting rod 321 and the second end of the second connecting rod 322 are respectively connected to the lower support node 3121 of the lower chord 312. The truss support member 300 has six upper support nodes 3111 and three lower support nodes 3121. The outermost component cables 210 and the outermost load-bearing cables 220 are located in the same vertical direction. Specifically, the outermost component cables 210 and the outermost load-bearing cables 220 are both connected to the corners of the rectangle. The upper chord 311 of the truss support member 300 is connected one-to-one with the six component cables 210 via the six upper support nodes 3111. The lower chord 312 of the truss support member 300 is connected one-to-one with the three load-bearing cables 220 via the three lower support nodes 3121. This expands the cross-section of the truss formed by the component cables 210 and the load-bearing cables 220, thereby increasing the torsional resistance of the overall structural cross-section.

[0065] Steel strands may be optionally used for the component cables 210 and the load-bearing cables 220. The use of component cables 210, load-bearing cables 220, and rectangular closed truss supports 300 can effectively increase the torsional resistance of the structure as a whole. Under the action of pulsating wind, the wind-induced torsion effect can be reduced, preventing the generation of divergent reversal motion. Since wind suction is usually greater than wind pressure and plays a controlling role, under wind suction conditions, only the component cables 210 located on the upper chord 311 are effective, while the load-bearing cables 220 located on the lower chord 312 have an adverse effect. Therefore, by adopting an arrangement of six component cables 210 on the upper side and three load-bearing cables 220 on the lower side, the role of each steel strand can be fully utilized under limited material conditions, reducing costs and increasing efficiency.

[0066] It should be noted that this application mainly takes three horizontal rows of photovoltaic modules as the minimum basic unit as an example. Specifically, four horizontal rows, five horizontal rows or other more horizontal rows of photovoltaic modules can be set according to actual conditions, and the number of connecting members 320 can be adjusted according to the number of horizontal rows of installed photovoltaic modules, and the truss support members 300 used can be further adjusted to meet different installation requirements.

[0067] Reference Figure 3 、 Figure 4 To disperse stress, improve load-bearing capacity, and enhance overall structural stability, in one embodiment, the support cable assembly 200 assumes an inverted arch shape. To achieve this, multiple truss supports 300 are arranged from one end of the support cable assembly 200 to the other. The lower chord 312 of the truss supports 300 located near the center of the support cable assembly 200 is lower than the lower chord 312 of the truss supports 300 located near the ends. By adjusting the support member heights in this way, the support cable assembly 200 naturally assumes an inverted arch shape, ensuring that supports at different locations share the load, reducing localized concentrated stress, and improving the load-bearing capacity and durability of the entire structure.

[0068] It is understood that the support cable group 200 is segmented by two adjacent brackets, which include but are not limited to end brackets, intermediate brackets, etc. The "truss support member disposed near the middle of the support cable group 200" refers to the truss support member disposed between the two brackets; the "truss support member disposed near the end" refers to the truss support member disposed near a bracket (such as an end bracket, an intermediate bracket, etc.). Specifically, the truss support member 300 can be disposed according to the actual position of the corresponding bracket, or the truss support member 300 can be disposed only between the two brackets. The embodiments of this application are mainly described by taking the example of disposing the truss support member 300 only between the two brackets:

[0069] The truss support member 300 comprises a rectangular support frame 310. In the assembled state, the height of the rectangle corresponds to the vertical direction, and the length of the rectangle is parallel to the second direction. The height of the lower chord 312 of the truss support member 300 refers to the vertical height of the lower chord 312 in the assembled state. The height position H0 of the lower chord 312 of the truss support member 300 located near the middle of the support cable assembly 200 is lower than the height position H2 of the lower chord 312 of the truss support member 300 located near the end. The lower chord 312 increases in height towards the end, but its maximum height is no greater than the support height H1, i.e., H1 > H2 > H0.

[0070] In order to increase the laying rate, increase the power generation, and improve the stability of the structure, and ensure safety and stability under different environmental conditions, in some specific embodiments of the present application, the upper chords 311 of multiple truss supports 300 are arranged at the same height, and the flexible photovoltaic support assembly is laid flat on the assembly cable 210 through the upper chord 311 of the truss support 300, and the height dimension L0 of the truss support 300 set near the middle of the support cable group 200 is set to be greater than the height dimension L1 of the truss support 300 set near the end. The closer to the middle, the greater the height dimension of the truss support 300 (L0>L1), so that the height of the lower chord 312 of the truss support 300 set near the middle of the support cable group 200 is less than the height of the lower chord 312 of the truss support 300 set near the end.

[0071] Such a setting can prevent the flexible photovoltaic support assembly from deforming or becoming unstable when bearing loads, thereby improving the stability of the structure, reducing deflection and stress concentration, and further improving the structural stiffness and stability, ensuring that the arrangement of the truss support members 300 and the load-bearing cables 220 is more regular and uniform.

[0072] Reference Figure 4 、 Figure 8 In one embodiment, each supporting cable group 200 is provided with a plurality of photovoltaic support members 400 for mounting photovoltaic modules, and the plurality of photovoltaic support members 400 are arranged along a first direction so that a plurality of photovoltaic modules 500 are laid on the supporting cable group 200 along the first direction.

[0073] In one embodiment, the photovoltaic support member 400 includes a horizontal bar 410 and a vertical bar 420, the horizontal bar 410 is used to connect to the photovoltaic module, one end of the vertical bar 420 is connected to the horizontal bar 410, and the other end of the vertical bar 420 is connected to the module cable 210, so as to construct an inclined installation surface for installing the photovoltaic module between the horizontal bar 410 and the vertical bar 420.

[0074] Specifically, photovoltaic module 500 includes a module frame, a horizontal bar 410 for connecting to the module frame, and a vertical bar 420 connected between the horizontal bar 410 and the module cable 210. As an optional embodiment, the vertical bar 420 and the horizontal bar 410 (and / or the vertical bar 420 and the module cable 210) are rotatably connected. Adjusting the angle of connection between the vertical bar 420 and the horizontal bar 410 (and / or the vertical bar 420 and the module cable 210) allows adjustment of the tilted mounting surface, thereby further adjusting the mounting angle of photovoltaic module 500. As another optional embodiment, the vertical bar 420 and the horizontal bar 410 (or the vertical bar 420 and the module cable 210) are perpendicular to each other. By using horizontal bars 410 and vertical bars 420 of predetermined dimensions, a desired tilted mounting surface can be constructed, further adjusting the mounting angle of the photovoltaic module.

[0075] By setting up the inclined mounting surface, solar radiation can be received to a greater extent, discharge efficiency can be improved, and power generation can be increased. At the same time, the impact of obstructions from obstacles can be reduced, and the photovoltaic modules can be kept clean, avoiding the impact of dust, snow, etc. on normal use when used in extreme environments such as dusty environments and low-temperature environments. The photovoltaic support 400 uses a vertical rod 420 and a full-length horizontal rod 410 of the photovoltaic support 400. The horizontal rod 410 is arranged close to the component frame of the photovoltaic module 500. The overall structure is connected at the node position to ensure that each rod of the photovoltaic support 400 is only subjected to axial force but not bending moment. At the same time, it avoids the complex situation of the component frame of the photovoltaic module 500 being subjected to force, ensures the stability of the connection structure, and reduces the impact of external environmental forces on the photovoltaic module, so as to better protect the photovoltaic module.

[0076] In one embodiment, the photovoltaic support members 400 are positioned identically on two adjacent support cable assemblies 200. This arrangement facilitates installation and maintenance, and allows the photovoltaic modules 500 to be arranged in a matrix, effectively utilizing floor space, improving discharge efficiency, and reducing the effects of wind and snow loads.

[0077] The flexible photovoltaic support assembly of the present application is applied to a photovoltaic power station. The photovoltaic power station is provided with multiple flexible photovoltaic support assemblies. The total number of photovoltaic components installed in each flexible photovoltaic support assembly, the number of horizontal rows of photovoltaic components, etc. can be the same or different, and are not limited here.

[0078] In one embodiment, the multiple brackets include at least two end brackets 110. To reduce floor space, the two end brackets 110 are spaced apart. The support cable assembly 200 spans between the two end brackets 110. By adjusting the distance between the two end brackets 110 to accommodate support cable assemblies 200 of varying lengths and specifications, the system can be used to expand its scope of use and meet the diverse needs of different application scenarios.

[0079] Optionally, the end bracket 110 includes a plurality of first legs, which are optionally connected to form a triangle, an "Λ" shape, an inverted "Y" shape or any other stable structure to provide stable support.

[0080] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 To further optimize support stability, in one embodiment, the multiple brackets further include an intermediate bracket 120. The number of intermediate brackets 120 is one or more, and at least one intermediate bracket 120 is provided between the two end brackets 110. When multiple intermediate brackets 120 are provided, the multiple intermediate brackets 120 are spaced apart between the two end brackets 110.

[0081] The end bracket 110 includes at least one second support leg. When multiple second support legs are provided, the multiple second brackets are spaced apart along the second direction to connect into an inverted U-shape, a downward-opening E-shape, a "sun" shape or any other stable structure to further provide stable support.

[0082] The multiple brackets are spaced apart along the first direction, and optionally, the multiple brackets are independent of each other; or, the multiple brackets are connected into a whole. The specific arrangement may be based on actual conditions and is not limited here.

The support component adopts the flexible photovoltaic support component described in the above embodiment.
