Description

[0001] This application claims priority to Chinese Patent Application No. 202520683266.4, filed with the State Intellectual Property Office of China on April 11, 2025, entitled "A Support Structure and Flexible Tracking Photovoltaic System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of photovoltaic technology, and more specifically, to a support structure and a flexible tracking photovoltaic system. Background Technology

[0003] Flexible photovoltaic (PV) support structures are typically fixed. The tilt angle of the PV modules is determined by setting height differences between different load-bearing cables in the same row, based on the latitude of the flexible PV system. However, this tilt angle cannot be changed after the PV modules are installed, making them unable to adapt to different solar altitude angles and thus preventing the maximization of maximum power generation efficiency.

[0004] To enable photovoltaic modules to adapt to different solar altitude angles, beam structures are typically installed on the foundation structure. Rotary reducers and drive motors are mounted on these beam structures to rotate them, as exemplified by the flexible tracking photovoltaic support proposed in CN118249717A. However, the aforementioned end structure is rather bulky, requiring multiple non-standard components to be welded together for fixation. This results in significant production difficulties, numerous assembly steps, a large amount of welding, and high costs.

[0005] Therefore, how to simplify the end support structure while maximizing the power generation efficiency of flexible photovoltaic systems has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0023] Optionally, in the above-described support structure, the stay cable and the ear plate are connected by a connector, which restricts the slot for insertion into the ear plate.

[0053] The core of this application is to provide a support structure that simplifies the end support structure while maximizing the power generation efficiency of the flexible photovoltaic system.

[0054] Another core aspect of this application is to provide a flexible tracking photovoltaic system with the aforementioned support structure.

[0055] 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.

[0056] Flexible photovoltaic (PV) support structures are typically fixed. The tilt angle of the PV modules is determined by setting height differences between different load-bearing cables in the same row, based on the latitude of the flexible PV system. However, this tilt angle cannot be changed after the PV modules are installed, making them unable to adapt to different solar altitude angles and thus preventing the maximization of maximum power generation efficiency.

[0057] To enable photovoltaic modules to adapt to different solar altitude angles, existing technologies typically involve mounting beam structures on a foundation structure, with a rotary reducer and drive motor installed on the beam structure to rotate it. However, this end structure is rather bulky, requiring multiple non-standard components to be welded together for fixation, which increases production difficulty, assembly steps, welding volume, and cost.

[0058] Therefore, such as Figure 1 As shown in the figure, this application discloses a support structure 100, including an end support 10 and an end rotating assembly 20. The ear plate 1201 is formed by an integral bending process of the end mounting plate 120 and connected to the stay cable 13. This eliminates the constraints of weld quality, ensuring force transmission and stability, reducing installation steps, simplifying the structure of the end support 10, and enabling rapid installation. Furthermore, by placing the end rotating assembly 20 on one side of the end mounting frame 12, the photovoltaic panel module can be rotated, thereby maximizing the power generation efficiency of the flexible photovoltaic system.

[0059] The following will combine Figures 1 to 13 The support structure 100 disclosed in the embodiments of this application will be explained and described in detail.

[0060] like Figure 1As shown, the end bracket 10 may include an end support structure 11, an end mounting frame 12, and a stay cable 13. The end support structure 11 can be a foundation structure such as a concrete pile foundation or a steel structure column, and the end mounting frame 12 can be fixed to the top of the end support structure 11. Furthermore, as... Figure 5 As shown, the end mounting frame 12 may include two spaced-apart end mounting plates 120, each end mounting plate 120 having an integrally bent ear plate 1201. The stay cables 13 can be connected and fixed to the ear plates 1201 without being constrained by weld quality, ensuring force transmission and stability. Furthermore, it eliminates the need for clamps and other installation components required for connecting the stay cables 13 to the end support structure 11, reducing installation steps, simplifying the structure of the end bracket 10, and enabling rapid installation of the end bracket 10, thereby forming a stable stay cable 13 support system. Simultaneously, the end rotating component 20 can be installed on one side of the end mounting frame 12 to drive the photovoltaic modules on the cable component 201 to rotate, thus adapting to different solar altitude angles and maximizing the power generation efficiency of the flexible photovoltaic system.

[0061] For example, such as Figure 6 and Figure 7 As shown, the end mounting plate 120 can adopt a right-angled trapezoidal structure, and the wider side of the end mounting plate 120 is fixed to the top of the end support structure 11 to ensure the reliability of the connection between the end mounting plate 120 and the end support structure 11. Meanwhile, the ear plate 1201 is located near the wider side of the end mounting plate 120, and the ear plates 1201 of the two end mounting plates 120 can be bent in opposite directions to form a preset angle between the ear plate 1201 and the end mounting plate 120, thereby forming a stable triangular system. Optionally, the preset angle between the ear plate 1201 and the end mounting plate 120 can be 135° to 170°, so that the two stay cables 13 connected to the ear plate 1201 can form an angle of 20° to 90°, thereby improving the transmission efficiency of the tension of the stay cables 13 and enhancing out-of-plane stability.

[0062] like Figure 1 and Figure 3 As shown, one end of the stay cable 13 can be connected to the ear plate 1201 via a connector 14, and the other end of the stay cable 13 can be connected to the fixed seat 15 via a U-shaped buckle 16. At the same time, the fixed seat 15 can be fixed to the upper surface of the pile foundation via bolts or other fasteners, or the fixed seat 15 can be pre-embedded in the pile foundation to achieve the connection and fixation between the fixed seat 15 and the pile foundation, thereby forming the stay cable 13 support system.

[0063] For example, such as Figure 1As shown, the connector 14 can have a cylindrical structure and can form a slot 140 for insertion into the ear plate 1201. The two side walls of the slot 140 are respectively provided with first mounting holes, and the ear plate 1201 is provided with a second mounting hole that mates with the first mounting hole. When the slot 140 of the connector 14 is inserted into the ear plate 1201, the first mounting hole and the second mounting hole are aligned. At this time, a pin can be inserted through the first mounting hole and the second mounting hole to connect and fix the connector 14 to the ear plate 1201. It should be noted that the connector 14 and the stay cable 13 can be connected by welding or threading to achieve the connection and fixation between the connector 14 and the stay cable 13.

[0064] To ensure a reliable connection between the end mounting bracket 12 and the end support structure 11, such as Figure 1 and Figure 5 As shown, the end mounting bracket 12 may also include an end connecting plate 123 connected to the end support structure 11, and the end mounting plate 120 is welded to the end connecting plate 123 to ensure that there is a large connection area between the end mounting bracket 12 and the end support structure 11, thereby improving the reliability of the connection between the end mounting bracket 12 and the end support structure 11.

[0065] For example, the end connecting plate 123 can be fixed to the upper surface of the end support structure 11 by fasteners such as bolts, or the end connecting plate 123 can be pre-embedded in the end support structure 11, thereby ensuring a reliable connection between the end connecting plate 123 and the end support structure 11. It should be noted that the end connecting plate 123 can be circular, square, or other shapes, and the specific shape can be determined according to the cross-sectional shape of the end support structure 11.

[0066] like Figure 1 and Figure 2 As shown, the end rotation assembly 20 may include an end rotation beam 21 connected to the cable assembly 201 and an end drive device 22 for driving the end rotation beam 21 to rotate, and the end rotation beam 21 and the end drive device 22 are connected by an end flange plate 23.

[0067] To facilitate the connection between the end drive device 22 and the end mounting bracket 12, such as Figure 6 and Figure 7 As shown, the end mounting bracket 12 may also include an end fixing plate 121 that is detachably connected to the end drive device 22, and the end fixing plate 121 may be fixed between the two end mounting plates 120 by welding.

[0068] For example, such as Figures 5 to 8As shown, the end fixing plate 121 and the ear plate 1201 can be located on the same side of the end mounting plate 120, that is, both the end fixing plate 121 and the ear plate 1201 are located on the side of the end mounting plate 120 closest to the end rotating assembly 20 (the right-angled side of the end mounting plate 120), and the end fixing plate 121 has a clearance notch 1211 to avoid the ear plate 1201, so that the end fixing plate 121 has a T-shaped structure, thereby avoiding the problem that the end fixing plate 121 cannot be installed due to the dimensional deviation between the end mounting plate 120 and the ear plate 1201. The area above the clearance notch 1211 of the end fixing plate 121 can be fixed to the end mounting plate 120 by welding. In addition, as Figures 5 to 7 As shown, a plurality of fixing holes for mounting the end drive device 22 are distributed in a ring above the clearance notch 1211 of the end fixing plate 121, so that the end drive device 22 can be connected to the end fixing plate 121 by fasteners such as bolts.

[0069] like Figure 8 As shown, the ear plate 1201 may have an upwardly projecting end 1202 facing away from the end support structure 11, so that the cable 13 can be connected to the upwardly projecting end 1202 of the ear plate 1201 via the connector 14, thereby avoiding interference with the end support structure 11.

[0070] For example, such as Figure 8 As shown, the upward-pointing end 1202 can be raised by 45°, that is, the angle between the upward-pointing end 1202 and the upper surface of the end support structure 11 is 45°, so that the stay cable 13 can be connected to the upward-pointing end 1202 of the ear plate 1201 through the connector 14, thereby allowing the end support structure 11 to effectively avoid the connection between the stay cable 13 and the ear plate 1201 through the connector 14.

[0071] like Figure 8 As shown, a recessed portion 1203 can be formed at the connection position between the ear plate 1201 and the end mounting plate 120 to avoid the rotation of the end rotating beam 21, thereby allowing the end rotating beam 21 to have a larger rotation angle and avoiding interference with the ear plate 1201.

[0072] For example, such as Figure 8 As shown, the ear plate 1201 is inclined towards the upward end 1202 from the connection position with the end mounting plate 120 to form a concave portion 1203, thereby ensuring that the end rotating beam 21 has a larger rotation angle, so that the ear plate 1201 can effectively avoid the end rotating beam 21.

[0073] To ensure the reliability of the connection between the end fixing plate 121 and the end mounting plate 120, such as Figures 5 to 7As shown, multiple reinforcing partitions 122 can be provided between the two end mounting plates 120 to reinforce the end mounting plates 120 and improve their stability, thereby ensuring the overall stability of the end mounting frame 12. At the same time, at least one reinforcing partition 122 abuts against the lower side of the end fixing plate 121 to support the end fixing plate 121, reduce the pressure on the weld connecting the end fixing plate 121 and the end mounting plate 120, and at the same time improve the overall stability of the end mounting frame 12.

[0074] For example, for ease of understanding, the reinforcing partition 122 abutting against the lower side of the end fixing plate 121 is defined as the supporting partition 1220, such as... Figure 9 As shown, the support partition 1220 may include a variable-width section and a constant-width section. The variable-width section has a narrow end and a wide end, and the width of the variable-width section gradually increases from the narrow end to the wide end. The constant-width section is connected to the narrow end of the variable-width section so that the constant-width section can accommodate the width between the two end mounting plates 120. Simultaneously, the variable-width section can accommodate the width between the two ear plates 1201 that are bent in opposite directions, ensuring the reliability of the connection between the support partition 1220 and the end mounting bracket 12, improving the overall stability of the end mounting bracket 12, and providing better support for the end fixing plate 121, reducing the pressure on the weld seam connecting the end fixing plate 121 and the end mounting plate 120.

[0075] Of course, the end fixing plate 121 can also be directly extended to the end connecting plate 123 and welded to the end connecting plate 123. At the same time, the two sides of the end fixing plate 121 are welded to the two end mounting plates 120 respectively. Two, three or more reinforcing partitions 122 can be provided between the two end mounting plates 120 to improve the overall stability of the end mounting frame 12.

[0076] To ensure the continuity of the welds between the supporting partition 1220, the end mounting plate 120, and the ear plate 1201, such as Figure 6 and Figure 7 As shown, a welding notch 1212 may be provided on the lower side of the end fixing plate 121, so as to ensure that the weld between the support partition plate 1220, the end mounting plate 120 and the ear plate 1201 remains continuous and will not be broken by the end fixing plate 121. At the same time, it is convenient to extend the welding torch into the welding notch 1212 to weld between the support partition plate 1220, the end mounting plate 120 and the ear plate 1201 during welding, thereby improving welding efficiency and welding quality.

[0077] For example, such as Figure 7As shown, the two corners on the lower side of the end fixing plate 121 can each be provided with a 45° inclined chamfer, so that welding notches 1212 are formed at the two corners on the lower side of the end fixing plate 121, thereby ensuring that the welds between the two sides of the support partition plate 1220 and the end mounting plate 120 and the ear plate 1201 remain continuous, thus improving welding efficiency and welding quality.

[0078] like Figures 1 to 3 As shown, the end drive device 22 may include an end horizontal reducer 220 and an end drive motor 221 that drives the end horizontal reducer 220. The end horizontal reducer 220 can be connected to the end rotating beam 21 through the end flange plate 23, and the end horizontal reducer 220 is connected and fixed to the end fixing plate 121 by bolts or other fasteners.

[0079] For example, such as Figure 4 As shown, the end flange plate 23 can adopt an approximately circular structure, and the end flange plate 23 is welded to the side of the end rotating beam 21 near the end mounting bracket 12. The end horizontal reducer 220 and the end flange plate 23 can be connected by bolts or other fasteners. Meanwhile, the end rotating beam 21 has two opposing connecting surfaces 210, namely the top surface and the bottom surface of the end rotating beam 21. Multiple end reinforcing ribs 2101 connected to the end flange plate 23 are provided on each connecting surface 210. That is, there can be two, three, or more end reinforcing ribs 2101, and the end reinforcing ribs 2101 can adopt a triangular structure, such that one side of the end reinforcing rib 2101 is welded to the connecting surface 210 of the end rotating beam 21, and the other side of the end reinforcing rib 2101 is welded to the end flange plate 23. In this way, while reinforcing the weld connection between the end flange plate 23 and the end rotating beam 21, the end reinforcing ribs 2101 on the two connecting surfaces 210 of the end rotating beam 21 can also provide vertical constraints between the end rotating beam 21 and the end flange plate 23. This can further provide vertical constraints between the end rotating beam 21 and the end horizontal reducer 220, thereby improving the stability of the connection between the end rotating beam 21 and the end horizontal reducer 220 when the end rotating beam 21 is subjected to unbalanced overturning force.

[0080] like Figure 10As shown, the cable assembly 201 may include a main cable 2011 and a stabilizing cable 2012, and the main cable 2011 and the stabilizing cable 2012 may be fixed to the two connecting surfaces 210 of the end rotating crossbeam 21 via end cable holders 211. Under the prestress of the four cables, the force between the end horizontal reducer 220 and the end fixing plate 121 is under compression. The pressure is directly transmitted to the end mounting plate 120 through the end fixing plate 121, and the weld between the end fixing plate 121 and the end mounting plate 120 can play an auxiliary role in compression, which can avoid the unfavorable stress form of tension at the critical weld.

[0081] For example, such as Figure 4 and Figure 10 As shown, the end cable holder 211 may include a connecting plate, which is welded to the side of the end rotating beam 21 away from the end mounting bracket 12. The connecting plate has through holes for the main cable 2011 and the stabilizing cable 2012 to pass through, allowing them to be locked in place at the ends. Furthermore, reinforcing plates connected to the connecting plate can be welded to the two connecting surfaces 210 of the end rotating beam 21. These reinforcing plates may have a triangular structure, allowing one side to be welded to the connecting surface 210 of the end rotating beam 21, and the other side to be welded to the connecting plate, thus reinforcing the weld connection between the connecting plate and the end rotating beam 21.

[0082] The support structure 100 disclosed in this application embodiment comprises an end mounting frame 12 disposed on an end support structure 11, with each of the two end mounting plates 120 of the end mounting frame 12 having an integrally bent ear plate 1201 for connecting the stay cable 13 to the ear plate 1201, thereby forming a stable stay cable 13 support system. Simultaneously, an end rotation component 20 is disposed on one side of the end mounting frame 12, and can drive the photovoltaic module on the cable assembly 201 to rotate to adapt to different solar altitude angles.

[0083] The support structure disclosed in this application embodiment can form the ear plate 1201 and the cable 13 by integral bending and forming the end mounting plate 120. It is not subject to the constraints of weld quality, which can ensure the transmission of force and stability. It can also reduce the installation process, simplify the structure of the end support 10, and realize the rapid installation of the end support 10. At the same time, by setting the end rotating component 20 on one side of the end mounting frame 12, the photovoltaic panel module can be driven to rotate, thereby maximizing the power generation efficiency of the flexible photovoltaic system.

[0084] When the span of a flexible tracking photovoltaic system is large, such as Figures 11 to 13As shown, the support structure 100 may further include a central support 30 and a central rotating assembly 40. The central support 30 may include a central support structure 31 and a central mounting frame 32 disposed on the central support structure 31. The central support structure 31 may be a foundation structure such as a concrete pile foundation or a steel structure column, and the central mounting frame 32 may be fixed to the top of the central support structure 31. The central mounting frame 32 may include a pipe body 320 and a central mounting plate 321 connected to the pipe body 320 by welding. Meanwhile, the central rotating assembly 40 may include a central rotating beam 41 connected to the cable assembly 201 through a central cable holder 410 and a central driving device 42 for driving the central rotating beam 41 to rotate. The central driving device 42 may be mounted on the central mounting plate 321 by bolts or other fasteners.

[0085] For example, such as Figure 11 and Figure 12 As shown, the central cable holder 410 may include a pressure plate, which arches away from the central rotating beam 41 to form a space through which the main cable 2011 or the stabilizing cable 2012 of the cable assembly 201 can pass. The pressure plate is connected and fixed to the central rotating beam 41 by bolts or other fasteners. When the main cable 2011 and the stabilizing cable 2012 pass through the top and bottom surfaces of the central rotating beam 41, respectively, the pressure plate can fix the main cable 2011 and the stabilizing cable 2012 to the top and bottom surfaces of the central rotating beam 41, respectively. This allows the central drive device 42 to drive the central rotating beam 41 to rotate, thereby rotating the photovoltaic modules on the cable assembly 201.

[0086] Because the horizontal tension in the mid-span of a flexible tracking photovoltaic system is relatively small, such as Figure 11 As shown, the central drive unit 42 may include a central vertical reducer 420 and a central drive motor 421 that drives the central vertical reducer 420, thereby saving costs. The central rotating beam 41 is connected to the central vertical reducer 420 via a central flange plate 43, and the central rotating beam 41 is located between the central vertical reducer 420 and the central flange plate 43. The central vertical reducer 420 and the central flange plate 43 are connected and fixed by bolts or other fasteners.

[0087] To ensure a reliable connection between the central mounting bracket 32 ​​and the central support structure 31, such as Figure 11 As shown, the central mounting bracket 32 ​​may also include a central connecting plate 322 connected to the central support structure 31, and the tube body 320 is welded to the central connecting plate 322. At the same time, multiple central reinforcing ribs 3201 are provided on the outer side of the tube body 320 to ensure that there is a large connection area between the central mounting bracket 32 ​​and the central support structure 31, thereby improving the reliability of the connection between the central mounting bracket 32 ​​and the central support structure 31.

[0088] For example, such as Figure 11 As shown, the pipe body 320 can be made of square steel pipe, and central reinforcing ribs 3201 are provided around the pipe body 320 to ensure a large connection area between the central mounting bracket 32 ​​and the central support structure 31. Meanwhile, the central connecting plate 322 can be fixed to the upper surface of the central support structure 31 by bolts or other fasteners, or the central connecting plate 322 can be pre-embedded within the central support structure 31, thereby ensuring a reliable connection between the central connecting plate 322 and the central support structure 31. It should be noted that the central connecting plate 322 can be circular, square, or other shapes, and the specific shape can be determined according to the cross-sectional shape of the central support structure 31.

[0089] like Figure 13 As shown in the illustration, this application also discloses a flexible tracking photovoltaic system 200, including photovoltaic modules, cable components 201, and a support structure 100 as disclosed in the above embodiments. Therefore, the flexible tracking photovoltaic system 200 possesses all the technical effects of the support structure 100, which will not be repeated here. The cable component 201 may include a main cable 2011 and a stabilizing cable 2012 located below the main cable 2011. The main cable 2011 and the stabilizing cable 2012 are respectively connected to the support structure 100, and the photovoltaic modules can be laid on the main cable 2011. Furthermore, multiple wind-resistant frames can be set between the main cable 2011 and the stabilizing cable 2012 to form a four-cable wind-resistant system, ensuring the wind resistance performance of the flexible tracking photovoltaic system 200. It should be noted that... Figure 13 The photovoltaic module is omitted, and the connection between the photovoltaic module and the main cable 2011 can be made using known conventional methods.
