[0001] This application claims priority to Chinese Patent Application No. 202520683267.9, filed on April 11, 2025, entitled "A Flexible Photovoltaic Support and Flexible 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 flexible photovoltaic bracket and a flexible photovoltaic system. Background Technology

[0003] To improve the wind resistance of flexible photovoltaic (PV) systems, wind-resistant frames are typically installed on the PV support structure. To prevent these frames from being subjected to wind suction and uplift, they are usually connected to ground anchors via vertical cables to limit vertical displacement caused by wind suction and uplift. However, the ground anchors are usually located at the mid-span, which prevents the full utilization of the large span and high clearance advantages of flexible PV systems.

[0004] Therefore, how to realize the advantages of large span and large clearance of flexible photovoltaic brackets has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The two ends of the wind-resistant cable are respectively connected to the support structure, and the first wind-resistant frame has a first side and a second side arranged opposite to each other. The first side of the first wind-resistant frame is connected to the main cable assembly. The wind-resistant cable is connected to the first wind-resistant frame through a first vertical cable, so that the middle part of the wind-resistant cable arches upward. The second side of the first wind-resistant frame arches towards the first side close to the first wind-resistant frame to form a clearance space for the arching of the wind-resistant cable.

[0019] The second wind-resistant frame includes at least one planar wind-resistant frame, which includes a second upper chord, a second lower chord, and a second connecting rod. The two ends of the second upper chord are respectively connected to the two ends of the second lower chord through the second connecting rod.

[0020] Optionally, in the above-mentioned flexible photovoltaic support, the second wind-resistant frame includes two planar wind-resistant frames, and the two planar wind-resistant frames share a second lower chord.

[0021] Optionally, in the above-mentioned flexible photovoltaic support, at least one second reinforcing link is connected between the second links of the two planar wind-resistant frames.

In this way, the advantages of large span and large clearance of the flexible photovoltaic support can be realized.

Detailed Implementation

[0046] The core of this application is to provide a flexible photovoltaic support structure to realize the advantages of large span and large clearance of flexible photovoltaic supports.

[0047] Another core aspect of this application is to provide a flexible photovoltaic system with the aforementioned flexible photovoltaic support.

[0048] 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.

[0049] To improve the wind resistance of flexible photovoltaic (PV) systems, wind-resistant frames are typically installed on the PV support structure. To prevent these frames from being subjected to wind suction and uplift, they are usually connected to ground anchors via vertical cables to limit vertical displacement caused by wind suction and uplift. However, the ground anchors are usually located at the mid-span, which prevents the full utilization of the large span and high clearance advantages of flexible PV systems.

[0050] Therefore, such as Figure 1 As shown in the illustration, this application discloses a flexible photovoltaic support system, including a main cable assembly 100, a support structure 200, and a wind-resistant assembly 300. By arching the second side of the first wind-resistant frame 32 towards the first side, a clearance space 33 is formed to facilitate the arching of the wind-resistant cable 31. This not only limits the vertical displacement of the first wind-resistant frame 32 caused by wind suction and lifting, but also improves the space utilization under the photovoltaic modules of the flexible photovoltaic support system and increases the span of the flexible photovoltaic support system, thereby achieving the advantages of a large span and large headroom for the flexible photovoltaic support system.

[0051] The following will combine Figures 1 to 13 The flexible photovoltaic support disclosed in the embodiments of this application will be explained and described in detail.

[0052] Among them, such as Figure 1 As shown, the main cable assembly 100 may include at least two parallel main cables 11 for laying photovoltaic modules on the main cables 11 and rigidly connecting them to the main cables 11. The main cables 11 may be, but are not limited to, two parallel main cables, or may include four or more, to ensure the stability of the photovoltaic module connection.

[0053] like Figure 1 As shown, the support structure 200 may include at least two, with the two support structures 200 located at opposite ends of the main cable assembly 100 to anchor the main cable assembly 100, thereby bearing the tensile force from the main cable assembly 100 and transmitting it to the ground foundation. Of course, the support structure 200 may be, but is not limited to, two, three, four, or more, to form a multi-span flexible photovoltaic support system. The specific number of support structures 200 can be determined according to the span of the flexible photovoltaic support system.

[0054] To improve the wind resistance and stability of flexible photovoltaic systems, such as Figure 1As shown, the wind-resistant component 300 may include a wind-resistant cable 31 and a first wind-resistant frame 32. The first wind-resistant frame 32 has upper and lower sides arranged opposite each other. For ease of understanding, the upper and lower sides of the first wind-resistant frame 32 are defined as the first side and the second side, respectively. The first side of the first wind-resistant frame 32 is connected to the main cable assembly 100. The two ends of the wind-resistant cable 31 are respectively connected to the support structure 200, and the wind-resistant cable 31 is connected to the first wind-resistant frame 32 via a first vertical cable 310 to limit the vertical displacement of the first wind-resistant frame 32 caused by wind suction and wind lifting, thereby improving the wind resistance performance of the flexible photovoltaic support. Simultaneously, the second side of the first wind-resistant frame 32 arches towards the first side closest to the first wind-resistant frame 32, forming a clearance space 33 for the middle arch of the wind-resistant cable 31. This allows the middle of the wind-resistant cable 31 to arch upwards, thereby improving the space utilization rate under the photovoltaic modules of the flexible photovoltaic support and increasing the span of the flexible photovoltaic support, realizing the advantages of large span and large clearance of the flexible photovoltaic support.

[0055] like Figure 2 As shown, the first wind-resistant frame 32 may include a first upper chord 320, a first lower chord 321, and a first connecting rod 322. The first lower chord 321 is on the same plane as the first upper chord 320. The first lower chord 321 is located below the first upper chord 320 and has an arc-shaped structure that arches towards the first upper chord 320. At the same time, the two ends of the first upper chord 320 and the two ends of the first lower chord 321 can be connected to each other through the first connecting rod 322 to form a planar truss system.

[0056] For example, such as Figure 2 As shown, the two ends of the first upper chord 320 can be bent to form two first connecting rods 322, thereby reducing the number of connection points of the first wind-resistant frame 32 and improving the stability and overall strength of the first wind-resistant frame 32. The two first connecting rods 322 are inclined in opposite directions, and the connection ends of the first connecting rods 322 and the first lower chord 321 are bent to form a first connecting part, so that the first connecting part fits better with the end of the first lower chord 321. This allows for connection and fixation by welding or bolts and other fasteners, ensuring the stability and reliability of the connection between the first connecting rods 322 and the first lower chord 321.

[0057] Of course, in the above embodiments, the two first connecting rods 322 can also adopt a separate structure from the first upper chord 320, that is, the two first connecting rods 322 can be connected to the first upper chord 320 by welding, and the two first connecting rods 322 are respectively connected to the two ends of the first lower chord 321 by welding to form the first wind-resistant frame 32.

[0058] like Figure 2As shown, a reinforcing structure 323 is provided between the first upper chord 320 and the first lower chord 321, and the reinforcing structure 323 is located between the two first connecting rods 322, so that the reinforcing structure 323 can strengthen the overall strength and rigidity of the first wind-resistant frame 32. The reinforcing structure 323 may include at least one first reinforcing connecting rod 3230, that is, the number of first reinforcing connecting rods 3230 can be one, two or more, and the first reinforcing connecting rods 3230 can be connected between the first upper chord 320 and the first lower chord 321.

[0059] For example, such as Figure 2 As shown, one first reinforcing link 3230 can be used. The first reinforcing link 3230 can be bent into a V-shaped structure, and the two ends of the V-shaped structure opening are bent to form two second connecting parts that connect with the first upper chord 320, so that the second connecting parts can be connected and fixed to the first upper chord 320 by bolts or other fasteners or welding. At the same time, the tip of the V-shaped structure forms a third connecting part that connects to the middle position of the first lower chord 321, so that the third connecting part can be connected and fixed to the middle position of the first lower chord 321 by bolts or other fasteners or welding, thereby improving the stability of the first wind-resistant frame 32.

[0060] For example, multiple first reinforcing links 3230 can be used, that is, two, three or more first reinforcing links 3230 can be used, and one end of each first reinforcing link 3230 can be welded to the center position of the first lower chord 321. At the same time, the other end of each first reinforcing link 3230 can be connected and fixed to the first upper chord 320 by bolts or other fasteners or by welding, so as to improve the stability of the first wind-resistant frame 32.

[0061] The flexible photovoltaic support disclosed in this application lays photovoltaic modules on a main cable assembly 100, and anchors both ends of the main cable assembly 100 through at least two support structures 200 to withstand the tension from the main cable assembly 100 and transfer it to the ground foundation. Furthermore, by connecting the first side of the first wind-resistant frame 32 to the main cable assembly 100, and connecting the wind-resistant cable 31 to the first wind-resistant frame 32 via a first vertical cable 310, and by arching the second side of the first wind-resistant frame 32 towards the first side to form a clearance space 33 that facilitates the arching of the wind-resistant cable 31, the vertical displacement of the first wind-resistant frame 32 due to wind suction and lifting can be limited, while simultaneously improving the space utilization under the photovoltaic modules of the flexible photovoltaic support and increasing the span of the flexible photovoltaic support.

[0062] The flexible photovoltaic support disclosed in this application embodiment arches the second side of the first wind-resistant frame 32 toward the direction closer to the first side to form a clearance space 33 that facilitates the arching of the wind-resistant cable 31. This can limit the vertical displacement of the first wind-resistant frame 32 caused by wind suction and wind lifting, while improving the space utilization rate under the photovoltaic modules of the flexible photovoltaic support and increasing the span of the flexible photovoltaic support. This enables the flexible photovoltaic support to achieve the advantages of large span and large headroom.

[0063] like Figure 1 As shown, the wind-resistant component 300 may further include a second wind-resistant frame 34, which has upper and lower sides arranged opposite to each other. For ease of understanding, the upper and lower sides of the second wind-resistant frame 34 are defined as the first side and the second side, respectively. The first side of the second wind-resistant frame 34 is connected to the main cable assembly 100, and the wind-resistant cable 31 is connected to the second wind-resistant frame 34 via the second vertical cable 340 to limit the vertical displacement of the second wind-resistant frame 34 caused by wind suction and wind lifting, thereby improving the wind resistance performance of the flexible photovoltaic support.

[0064] like Figure 4 As shown, the second wind-resistant frame 34 may include at least one planar wind-resistant frame 341. The planar wind-resistant frame 341 may include a second upper chord 3410, a second lower chord 3411, and a second connecting rod 3412. The second upper chord 3410 and the second lower chord 3411 are arranged parallel to each other, with the second lower chord 3411 located below the second upper chord 3410. Furthermore, both ends of the second upper chord 3410 are connected to both ends of the second lower chord 3411 via the second connecting rod 3412 to form a planar truss system.

[0065] To improve the overall stability of the second wind-resistant frame 34, such as Figure 4 As shown, the second wind-resistant frame 34 may include two planar wind-resistant frames 341. For example, the two planar wind-resistant frames 341 may be arranged parallel to each other along the extension direction of the main cable 11, or they may be arranged at a certain angle along the extension direction of the main cable 11. At the same time, the two planar wind-resistant frames 341 may be connected by connecting rods, and each connecting rod may be arranged parallel to each other or cross each other. Alternatively, the second upper chords 3410 of the two planar wind-resistant frames 341 may be connected by a connecting rod, and the second lower chords 3411 of the two planar wind-resistant frames 341 may be connected by a connecting rod. The connecting rods connecting the second upper chords 3410 and the connecting rods connecting the second lower chords 3411 may be arranged crosswise or parallel to each other.

[0066] Preferably, such as Figure 4As shown, the two planar wind-resistant frames 341 are arranged at a certain angle along the extension direction of the main cable 11, and the two planar wind-resistant frames 341 can share a second lower chord 3411. That is, the second lower chord 3411 can be located directly below the central axis of the two planes where the second upper chords 3410 of the two planar wind-resistant frames 341 are located. One end of the second connecting rod 3412 of the two planar wind-resistant frames 341 is connected to the end of the second upper chord 3410 of the two planar wind-resistant frames 341, and the other end of the second connecting rod 3412 of the two planar wind-resistant frames 341 is connected to the end of the second upper chord 3410 of the two planar wind-resistant frames 341. One end intersects at the end of the second lower chord 3411 to form a V-shaped structure. At the same time, at least one second reinforcing link 3413 can be connected between the second link 3412 on the same side of the two planar wind-resistant frames 341. That is, one, two or more second reinforcing links 3413 can be connected between the second link 3412 on the same side of the two planar wind-resistant frames 341, so that the second wind-resistant frame 34 has an inverted triangular cone-shaped spatial truss structure. This improves the overall stability of the second wind-resistant frame 34 while reducing the number of members and saving costs.

[0067] Of course, in the above embodiments, the two planar wind-resistant frames 341 can also share a second upper chord 3410, so that the second wind-resistant frame 34 is a equilateral triangular pyramidal space truss structure, which will not be elaborated here.

[0068] To improve the wind resistance and stability of flexible photovoltaic systems, such as Figure 1 As shown, the wind-resistant component 300 may further include at least one stabilizing cable 35, which is located below the main cable 11, and both ends of the stabilizing cable 35 are fixed to the support structure 200. The stabilizing cable 35 is rigidly connected to the second side of the first wind-resistant frame 32 and the second side of the second wind-resistant frame 34, thereby forming an integral spatial structure. This improves the overall stability of the flexible photovoltaic support and can effectively resist the torsion and collision of the photovoltaic module by wind load, snow load and gravity load, reducing the risk of damage to the photovoltaic module due to wind force, and also reducing the risk of microcracks and overturning of the photovoltaic module.

[0069] For example, such as Figure 1 , Figure 3 and Figure 5As shown, the stabilizing cable 35 can be one, but not limited to one; two, three, four, or more can also be used to improve the overall stability of the flexible photovoltaic support. Preferably, two stabilizing cables 35 can be used, and the two stabilizing cables 35 are respectively located below the two main cables 11, so that the first upper chord 320 of the first wind-resistant frame 32 and the second upper chord 3410 of the second wind-resistant frame 34 can be rigidly connected to the two main cables 11 through cable connectors 36, and the first lower chord 321 of the first wind-resistant frame 32 and the second lower chord 3411 of the second wind-resistant frame 34 can be rigidly connected to the two stabilizing cables 35 through cable connectors 36, thereby forming a four-cage spatial structure, which can improve the overall stability of the flexible photovoltaic support.

[0070] For example, such as Figure 3 , Figure 5 and Figure 13 As shown, the cable connector 36 may include a base 360 ​​and a U-shaped buckle 361 that mates with the base 360, and a through-hole is formed between the U-shaped buckle 361 and the base 360. When connecting the first upper chord 320, the second upper chord 3410 and the main cable 11, the main cable 11 is passed through the through-hole of the U-shaped buckle 361, and the two ends of the U-shaped buckle 361 pass through the two through holes opened on the ends of the first upper chord 320 or the second upper chord 3410 and the mounting hole of the base 360 ​​in sequence. After the washers 362 are fitted on both ends of the U-shaped buckle 361, the nuts 363 are threaded into the two ends of the U-shaped buckle 361 until the first upper chord 320, the second upper chord 3410 and the main cable 11 are locked. Similarly, when connecting the first lower chord 321, the second lower chord 3411, and the stabilizing cable 35, the stabilizing cable 35 is passed through the U-shaped buckle 361, and the two ends of the U-shaped buckle 361 pass through the two through holes opened on the first lower chord 321 or the second lower chord 3411 and the mounting hole of the base 360 ​​in sequence. After the washers 362 are put on both ends of the U-shaped buckle 361, the nuts 363 are threaded with the two ends of the U-shaped buckle 361 until the first lower chord 321, the second lower chord 3411, and the stabilizing cable 35 are locked.

[0071] Because the stress in the middle of the stabilizing cable 35 is relatively small, for example, Figure 1 As shown, the first wind-resistant frame 32 can be set in the middle of two adjacent support structures 200, and one or more second wind-resistant frames 34 can be set on both sides of the first wind-resistant frame 32. This can save costs while meeting the wind resistance and mechanical performance of the flexible photovoltaic support, while ensuring a large clearance height under the photovoltaic modules, improving the space utilization of the flexible photovoltaic support, and increasing the span of the flexible photovoltaic support, thus realizing the advantages of large span and large clearance of the flexible photovoltaic support.

[0072] To maximize the power generation efficiency of flexible photovoltaic systems, such as Figure 1As shown, the flexible photovoltaic support structure may further include a drive assembly 400, which may include a crossbeam assembly 41 and a drive element 42. The crossbeam assembly 41 is rotatably connected to the support structure 200, and the two ends of the main cable assembly 100 and the stabilizing cable 35 are respectively fixed to the crossbeam assembly 41. The drive element 42 is drively connected to the crossbeam assembly 41 to drive the crossbeam assembly 41 to rotate, thereby enabling adjustment of the angle of the photovoltaic modules and maximizing the power generation efficiency of the flexible photovoltaic system.

[0073] At the same time, such as Figure 3 and Figure 5 As shown, the first vertical cable 310 and the second vertical cable 340 can be connected to the rotation center of the first wind-resistant frame 32 and the second wind-resistant frame 34, respectively. When upward loads such as wind suction and wind lifting are applied, the upper nodes of the first vertical cable 310 and the second vertical cable 340 will not be displaced when the first wind-resistant frame 32 and the second wind-resistant frame 34 rotate with the main cable 11. In this way, the first vertical cable 310 and the second vertical cable 340 can only play a vertical restraint role on the first wind-resistant frame 32 and the second wind-resistant frame 34, and will not generate additional torque due to the rotation of the first wind-resistant frame 32 and the second wind-resistant frame 34.

[0074] For example, such as Figure 3 As shown, there can be two first vertical cables 310, each connected to the rotation center at the midpoint of the first upper chord 320 of the first wind-resistant frame 32. One end of each first vertical cable 310 can be connected to a pin passing through the midpoint of the first upper chord 320, and the other end can be connected to the wind-resistant cable 31 via a U-shaped shackle. Similarly, as... Figure 5 As shown, there can be two second vertical cables 340, and one end of each second vertical cable 340 is connected to the rotation center of the midpoint of the two second upper chords 3410 of the second wind-resistant frame 34 via a U-shaped shackle, and the other end of each second vertical cable 340 is connected to the wind-resistant cable 31 via a cable connector 36.

[0075] like Figure 1 As shown, the support structure 200 may include an end bracket 21. Wherein, as... Figure 6 As shown, the end bracket 21 may include an end support structure 210, an end mounting bracket 211, and a stay cable 23. The end support structure 210 may be a foundation structure such as a concrete pile foundation or a steel structure column, and the end mounting bracket 211 may be fixed to the top of the end support structure 210. Furthermore, as... Figure 6 and Figure 8As shown, the end mounting frame 211 may include two spaced-apart end mounting plates 2110, each end mounting plate 2110 having an integrally bent ear plate 2111. The stay cables 23 can be connected and fixed to the ear plates 2111 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 23 to the end support structure 210, reducing installation steps, simplifying the structure of the end bracket 21, and enabling rapid installation of the end bracket 21, thereby forming a stable stay cable 23 support system. Simultaneously, the drive component 400 can be installed on one side of the end mounting frame 211 to drive the photovoltaic modules on the main cable component 100 to rotate, thus adapting to different solar altitude angles and maximizing the power generation efficiency of the flexible photovoltaic system.

[0076] For example, such as Figure 8 As shown, the end mounting plate 2110 can adopt a right-angled trapezoidal structure, and the wider side of the end mounting plate 2110 is fixed to the top of the end support structure 210 to ensure the reliability of the connection between the end mounting plate 2110 and the end support structure 210. Meanwhile, the ear plates 2111 are located near the wider side of the end mounting plate 2110, and the ear plates 2111 of the two end mounting plates 2110 can be bent in opposite directions to form a preset angle between the ear plates 2111 and the end mounting plate 2110, thereby forming a stable triangular system. Optionally, the preset angle between the ear plates 2111 and the end mounting plate 2110 can be 135° to 170°, so that the two stay cables 23 connected to the ear plates 2111 can form an angle of 20° to 90°, thereby improving the transmission efficiency of the tension of the stay cables 23 and enhancing out-of-plane stability.

[0077] like Figure 6 As shown, one end of the stay cable 23 can be connected to the ear plate 2111 via a connector 24, and the other end of the stay cable 23 can be connected to the fixed seat 25 via a U-shaped buckle 26. At the same time, the fixed seat 25 can be fixed to the upper surface of the pile foundation via bolts or other fasteners, or the fixed seat 25 can be pre-embedded in the pile foundation to achieve the connection and fixation between the fixed seat 25 and the pile foundation, thereby forming the stay cable 23 support system.

[0078] For example, such as Figure 6As shown, the connector 24 can have a cylindrical structure and can form a slot 240 for insertion into the ear plate 2111. The two side walls of the slot 240 are respectively provided with first mounting holes, and the ear plate 2111 is provided with a second mounting hole that mates with the first mounting hole. When the slot 240 of the connector 24 is inserted into the ear plate 2111, 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 24 to the ear plate 2111. It should be noted that the connector 24 and the stay cable 23 can be connected by welding or threading to achieve the connection and fixation between the connector 24 and the stay cable 23.

[0079] To ensure a reliable connection between the end mounting bracket 211 and the end support structure 210, such as Figure 6 and Figure 8 As shown, the end mounting bracket 211 may also include an end connecting plate 2116 connected to the end support structure 210, and the end mounting plate 2110 is welded to the end connecting plate 2116 to ensure that there is a large connection area between the end mounting bracket 211 and the end support structure 210, thereby improving the reliability of the connection between the end mounting bracket 211 and the end support structure 210.

[0080] For example, the end connecting plate 2116 can be fixed to the upper surface of the end support structure 210 by fasteners such as bolts, or the end connecting plate 2116 can be pre-embedded in the end support structure 210, thereby ensuring a reliable connection between the end connecting plate 2116 and the end support structure 210. It should be noted that the end connecting plate 2116 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 210.

[0081] like Figure 1 and Figure 6 As shown, the crossbeam assembly 41 may include an end rotating crossbeam 411 connected to the main cable assembly 100 and the stabilizing cable 35, and the drive unit 42 may include an end drive device 421 for driving the end rotating crossbeam 411 to rotate. The end rotating crossbeam 411 and the end drive device 421 are both located on one side of the end mounting bracket 211, and the end rotating crossbeam 411 and the end drive device 421 are connected by an end flange plate 4113.

[0082] To facilitate the connection between the end drive device 421 and the end mounting bracket 211, such as Figure 6 and Figure 8 As shown, the end mounting bracket 211 may also include an end fixing plate 2112 that is detachably connected to the end drive device 421, and the end fixing plate 2112 may be fixed between the two end mounting plates 2110 by welding.

[0083] For example, such as Figure 8As shown, the end fixing plate 2112 and the ear plate 2111 can be located on the same side of the end mounting plate 2110, that is, both the end fixing plate 2112 and the ear plate 2111 are located on the side of the end mounting plate 2110 closest to the end drive device 421 (the right-angled side of the end mounting plate 2110). The end fixing plate 2112 has a clearance notch 2113 to avoid the ear plate 2111, making the end fixing plate 2112 T-shaped. This avoids the problem of the end fixing plate 2112 being unable to be installed due to dimensional deviations between the end mounting plate 2110 and the ear plate 2111. The area above the clearance notch 2113 of the end fixing plate 2112 can be fixed to the end mounting plate 2110 by welding. Furthermore, as... Figure 8 As shown, multiple fixing holes for mounting the end drive device 421 are distributed in a ring above the clearance notch 2113 of the end fixing plate 2112, so that the end drive device 421 can be connected to the end fixing plate 2112 by fasteners such as bolts.

[0084] like Figure 8 As shown, the ear plate 2111 may have an upwardly projecting end 2111-1 facing away from the end support structure 210, so that the stay cable 23 can be connected to the upwardly projecting end 2111-1 of the ear plate 2111 via the connector 24, thereby avoiding interference with the end support structure 210.

[0085] For example, such as Figure 8 As shown, the upward-pointing end 2111-1 can be raised by 45°, that is, the angle between the upward-pointing end 2111-1 and the upper surface of the end support structure 210 is 45°, so that the stay cable 23 can be connected to the upward-pointing end 2111-1 of the ear plate 2111 through the connector 24, thereby allowing the end support structure 210 to effectively avoid the connection between the stay cable 23 and the ear plate 2111 through the connector 24.

[0086] like Figure 8 As shown, a recessed portion 2111-2 can be formed at the connection position between the ear plate 2111 and the end mounting plate 2110 to avoid the rotation of the end rotating beam 411, thereby allowing the end rotating beam 411 to have a larger rotation angle and avoiding interference with the ear plate 2111.

[0087] For example, such as Figure 8 As shown, the ear plate 2111 is inclined towards the upward end 2111-1 from the connection position with the end mounting plate 2110 to form an inner recess 2111-2, thereby ensuring that the end rotating beam 411 has a larger rotation angle, so that the ear plate 2111 can effectively avoid the end rotating beam 411.

[0088] To ensure the reliability of the connection between the end fixing plate 2112 and the end mounting plate 2110, such as Figure 8 As shown, multiple reinforcing partitions 2114 can be provided between the two end mounting plates 2110 to reinforce the end mounting plates 2110 and improve their stability, thereby ensuring the overall stability of the end mounting frame 211. At the same time, at least one reinforcing partition 2114 abuts against the lower side of the end fixing plate 2112 to support the end fixing plate 2112, reduce the pressure on the weld connecting the end fixing plate 2112 and the end mounting plate 2110, and at the same time improve the overall stability of the end mounting frame 211.

[0089] For example, for ease of understanding, the reinforcing partition 2114 abutting against the lower side of the end fixing plate 2112 is defined as the supporting partition 2115, such as... Figure 9 As shown, the support partition 2115 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 2110. Simultaneously, the variable-width section can accommodate the width between the two ear plates 2111 that bend in opposite directions, ensuring the reliability of the connection between the support partition 2115 and the end mounting bracket 211, improving the overall stability of the end mounting bracket 211, and providing better support for the end fixing plate 2112, reducing the pressure on the weld joint connecting the end fixing plate 2112 and the end mounting plate 2110.

[0090] Of course, the end fixing plate 2112 can also be directly extended to the end connecting plate 2116 and welded to the end connecting plate 2116. At the same time, the two sides of the end fixing plate 2112 are welded to the two end mounting plates 2110 respectively, and two, three or more reinforcing partitions 2114 can be provided between the two end mounting plates 2110 to improve the overall stability of the end mounting frame 211.

[0091] To ensure the continuity of the welds between the supporting partition 2115, the end mounting plate 2110, and the ear plate 2111, such as Figure 8 As shown, a welding notch 2117 may be provided on the lower side of the end fixing plate 2112, so as to ensure that the weld between the support partition plate 2115, the end mounting plate 2110 and the ear plate 2111 remains continuous and will not be broken by the end fixing plate 2112. At the same time, it is convenient to extend the welding torch into the welding notch 2117 to weld between the support partition plate 2115, the end mounting plate 2110 and the ear plate 2111 during welding, thereby improving welding efficiency and welding quality.

[0092] For example, the two corners on the lower side of the end fixing plate 2112 can each be provided with a 45° inclined chamfer, so that welding notches 2117 are formed at the two corners on the lower side of the end fixing plate 2112, thereby ensuring that the welds between the two sides of the support partition 2115 and the end mounting plate 2110 and the ear plate 2111 remain continuous, thereby improving welding efficiency and welding quality.

[0093] like Figure 6 As shown, the end drive device 421 may include an end horizontal reducer 4210 and an end drive motor 4211 that drives the end horizontal reducer 4210. The end horizontal reducer 4210 can be connected to the end rotating beam 411 via an end flange plate 4113, and the end horizontal reducer 4210 is connected and fixed to the end fixing plate 2112 via bolts or other fasteners.

[0094] For example, such as Figure 7 As shown, the end flange plate 4113 can adopt an approximately circular structure, and the end flange plate 4113 is welded to the side of the end rotating beam 411 near the end mounting bracket 211. The end horizontal reducer 4210 and the end flange plate 4113 can be connected by bolts or other fasteners. Meanwhile, the end rotating beam 411 has two opposing connecting surfaces 4110, namely the top surface and the bottom surface of the end rotating beam 411. Multiple end reinforcing ribs 4111 connected to the end flange plate 4113 are provided on each connecting surface 4110. That is, there can be two, three, or more end reinforcing ribs 4111, and the end reinforcing ribs 4111 can adopt a triangular structure, such that one side of the end reinforcing rib 4111 is welded to the connecting surface 4110 of the end rotating beam 411, and the other side of the end reinforcing rib 4111 is welded to the end flange plate 4113. This strengthens the weld connection between the end flange plate 4113 and the end rotating beam 411, while also providing vertical constraints between the end rotating beam 4111 and the end flange plate 4113 through the end reinforcing ribs 4111 on the two connecting surfaces 4110 of the end rotating beam 411. This, in turn, provides vertical constraints between the end rotating beam 411 and the end horizontal reducer 4210, thereby improving the stability of the connection between the end rotating beam 411 and the end horizontal reducer 4210 when the end rotating beam 411 is subjected to unbalanced overturning forces.

[0095] like Figure 10As shown, the main cable 11 and the stabilizing cable 35 can be fixed to the two connecting surfaces 4110 of the end rotating beam 411 via the end cable holders 4112. Under the prestress of the four cables, the force between the end horizontal reducer 4210 and the end fixing plate 2112 is under compression. The pressure is directly transmitted to the end mounting plate 2110 through the end fixing plate 2112, and the weld between the end fixing plate 2112 and the end mounting plate 2110 can play an auxiliary role in compression, which can avoid the unfavorable tensile stress form of the critical weld.

[0096] For example, such as Figure 7 and Figure 10 As shown, the end cable holder 4112 may include a holder connecting plate, which is welded to the side of the end rotating crossbeam 411 away from the end mounting bracket 211. The holder connecting plate has through holes for the main cable 11 and the stabilizing cable 35 to pass through, allowing them to be locked in place at the end. Furthermore, reinforcing plates connected to the holder connecting plate can be welded to the two connecting surfaces 4110 of the end rotating crossbeam 411. These reinforcing plates may have a triangular structure, allowing one side to be welded to the connecting surface 4110 of the end rotating crossbeam 411 and the other side to the holder connecting plate, thus reinforcing the weld connection between the holder connecting plate and the end rotating crossbeam 411.

[0097] When the span of the flexible photovoltaic support is large, such as Figure 1 As shown, the support structure 200 may also include a central support 22. (As illustrated...) Figure 11 and Figure 12 As shown, the central support 22 may include a central support structure 220 and a central mounting frame 221 disposed on the central support structure 220. The central support structure 220 may be a foundation structure such as a concrete pile foundation or a steel structure column, and the central mounting frame 221 may be fixed to the top of the central support structure 220. The central mounting frame 221 may include a pipe body 2210 and a central mounting plate 2212 welded to the pipe body 2210. Meanwhile, the crossbeam assembly 41 may also include a central rotating crossbeam 412 connected to the main cable assembly 100 and the stabilizing cable 35 via a central cable holder 4120. The driving component 42 may also include a central driving device 422 for driving the central rotating crossbeam 412 to rotate, and the central driving device 422 may be mounted on the central mounting plate 2212 using bolts or other fasteners.

[0098] For example, such as Figure 11 and Figure 12As shown, the central cable holder 4120 may include a pressure plate, which arches away from the central rotating beam 412 to form a space through which the main cable 11 or the stabilizing cable 35 of the main cable assembly 100 can pass. The pressure plate is connected and fixed to the central rotating beam 412 by bolts or other fasteners. When the main cable 11 and the stabilizing cable 35 pass through the top and bottom surfaces of the central rotating beam 412, respectively, the pressure plate can fix the main cable 11 and the stabilizing cable 35 to the top and bottom surfaces of the central rotating beam 412, respectively. This allows the central drive device 422 to drive the central rotating beam 412 to rotate, thereby rotating the photovoltaic modules on the main cable assembly 100.

[0099] Because the horizontal tension in the mid-span of the flexible photovoltaic support is relatively small, such as Figure 11 As shown, the central drive unit 422 may include a central vertical reducer 4220 and a central drive motor 4221 that drives the central vertical reducer 4220, thereby saving costs. The central rotating beam 412 is connected to the central vertical reducer 4220 via a central flange plate 4121, and the central rotating beam 412 is located between the central vertical reducer 4220 and the central flange plate 4121. The central vertical reducer 4220 and the central flange plate 4121 are connected and fixed by bolts or other fasteners.

[0100] To ensure a reliable connection between the central mounting bracket 221 and the central support structure 220, such as Figure 11 As shown, the central mounting bracket 221 may also include a central connecting plate 2213 connected to the central support structure 220, and the tube body 2210 is welded to the central connecting plate 2213. At the same time, multiple central reinforcing ribs 2211 are provided on the outer side of the tube body 2210 to ensure that there is a large connection area between the central mounting bracket 221 and the central support structure 220, thereby improving the reliability of the connection between the central mounting bracket 221 and the central support structure 220.

[0101] For example, such as Figure 11 As shown, the pipe body 2210 can be made of square steel pipe, and central reinforcing ribs 2211 are provided around the pipe body 2210 to ensure a large connection area between the central mounting bracket 221 and the central support structure 220. Meanwhile, the central connecting plate 2213 can be fixed to the upper surface of the central support structure 220 by bolts or other fasteners, or the central connecting plate 2213 can be pre-embedded within the central support structure 220, thereby ensuring a reliable connection between the central connecting plate 2213 and the central support structure 220. It should be noted that the central connecting plate 2213 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 220.
