DETAILED DESCRIPTION

[0045] The core of this application is to provide a flexible photovoltaic bracket to achieve the advantages of large span and large clearance of the flexible photovoltaic bracket.

[0046] Another core of the present application is to provide a flexible photovoltaic system having the above-mentioned flexible photovoltaic bracket.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] In order to improve the wind resistance of flexible photovoltaic systems, wind-resistant frames are generally installed on photovoltaic brackets, and in order to prevent the wind-resistant frames from being sucked and lifted by wind, the wind-resistant brackets are usually connected to ground anchors through vertical cables to limit the vertical displacement of the wind-resistant brackets when they are sucked and lifted by wind. However, ground anchors are usually installed in the middle of the span, which makes it impossible to fully utilize the advantages of large spans and large clearances of flexible photovoltaic brackets.

[0049] For this reason, Figure 1 As shown, the embodiment of the present application discloses a flexible photovoltaic support, including a main cable assembly 100, a support structure 200 and a wind-resistant assembly 300. The second side of the first wind-resistant frame 32 is arched toward the direction close to the first side to form an escape space 33 for the wind-resistant cable 31 to arch, thereby limiting the vertical displacement of the first wind-resistant frame 32 caused by wind suction and wind lifting, and improving the space utilization rate under the photovoltaic assembly of the flexible photovoltaic support, and increasing the span of the flexible photovoltaic support, thereby achieving the advantages of large span and large clearance of the flexible photovoltaic support.

[0050] The following will be combined Figures 1 to 13 The flexible photovoltaic bracket disclosed in the embodiment of the present application is specifically explained and illustrated.

[0051] Among them, Figure 1 As shown, the main cable assembly 100 may include at least two parallel main cables 11, so that the photovoltaic assembly is laid on the main cables 11 and rigidly connected to the main cables 11. The main cables 11 may be, but are not limited to, two parallel main cables, or may be four or more main cables, to ensure the stability of the connection of the photovoltaic assembly.

[0052] like Figure 1 As shown, the support structure 200 may include at least two, and the two support structures 200 are respectively located at both ends of the main cable assembly 100 to anchor the main cable assembly 100, so as to withstand the tension from the main cable assembly 100 and transmit it to the ground foundation. Of course, the support structure 200 may be used but not limited to two, and may also be three, four or more to form a multi-span flexible photovoltaic support. The specific number of support structures 200 can be determined according to the span of the flexible photovoltaic support.

[0053] In order to improve the wind resistance and stability of flexible photovoltaic brackets, such as Figure 1 As shown, the wind-resistant assembly 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 that are relatively arranged. For ease of understanding, the upper and lower sides of the first wind-resistant frame 32 are defined as a first side and a second side, respectively. The first side of the first wind-resistant frame 32 is connected to the main cable assembly 100, and the two ends of the wind-resistant cable 31 are respectively connected to the supporting structure 200, and the wind-resistant cable 31 is connected to the first wind-resistant frame 32 through 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-resistant performance of the flexible photovoltaic bracket. At the same time, the second side of the first wind-resistant frame 32 is arched toward the first side close to the first wind-resistant frame 32 to form an escape space 33 with the middle part of the wind-resistant cable 31 arched, so that the middle part of the wind-resistant cable 31 can be arched upward, thereby improving the space utilization rate under the photovoltaic assembly of the flexible photovoltaic bracket, and improving the span of the flexible photovoltaic bracket, thereby achieving the advantages of large span and large clearance of the flexible photovoltaic bracket.

[0054] 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 and the first upper chord 320 are in the same plane, the first lower chord 321 is located below the first upper chord 320, and the first lower chord 321 is an arc-shaped structure arched toward 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 respectively by the first connecting rod 322 to form a planar truss system.

[0055] For example, Figure 2 As shown, the two ends of the first upper chord 320 can be bent to form two first connecting rods 322, so as to reduce the connection points of the first wind-resistant frame 32 and improve the stability and overall strength of the first wind-resistant frame 32. The two first connecting rods 322 are inclined in directions away from each other, and at the same time, the connecting end of the first connecting rod 322 and the first lower chord 321 is bent to form a first connecting portion, so that the first connecting portion and the end of the first lower chord 321 are better fitted, so that they can be connected and fixed by fasteners such as welding or bolts, thereby ensuring the stability and reliability of the connection between the first connecting rod 322 and the first lower chord 321.

[0056] Of course, in the above embodiment, the two first connecting rods 322 can also adopt a split structure with 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 at the same time, 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.

[0057] like Figure 2As shown, a reinforcement structure 323 is provided between the first upper chord 320 and the first lower chord 321, and the reinforcement structure 323 is located between the two first connecting rods 322, so that the overall strength and rigidity of the first wind-resistant frame 32 can be reinforced by the reinforcement structure 323. The reinforcement structure 323 may include at least one first reinforcement connecting rod 3230, that is, the number of the first reinforcement connecting rods 3230 may be one, two or more, and the first reinforcement connecting rod 3230 may be connected between the first upper chord 320 and the first lower chord 321.

[0058] For example, Figure 2 As shown, the first reinforcing link 3230 can be one, and the first reinforcing link 3230 can be bent to form a V-shaped structure, and the two ends of the opening of the V-shaped structure are respectively bent to form two second connection parts connected to the first upper chord 320, so that the second connection parts can be connected and fixed to the first upper chord 320 by fasteners such as bolts or welding. At the same time, the tip of the V-shaped structure is formed with a third connection part connected to the middle position of the first lower chord 321, so that the third connection part can be connected and fixed to the middle position of the first lower chord 321 by fasteners such as bolts or welding, thereby improving the stability of the first wind-resistant frame 32.

[0059] Exemplarily, multiple first reinforcing links 3230 may be used, that is, two, three or more first reinforcing links 3230 may be used, and one end of each first reinforcing link 3230 may be intersectingly welded to the center position of the first lower chord 321, and at the same time, the other end of each first reinforcing link 3230 may be respectively connected and fixed to the first upper chord 320 by fasteners such as bolts or welding, so as to improve the stability of the first wind-resistant frame 32.

[0060] The flexible photovoltaic support disclosed in the embodiment of the present application is provided by laying the photovoltaic assembly on the main cable assembly 100, and anchoring the two ends of the main cable assembly 100 through at least two supporting structures 200, so as to bear the tension from the main cable assembly 100 and transmit it to the ground foundation. In addition, by connecting the first side of the first wind-resistant frame 32 to the main cable assembly 100, and the wind-resistant cable 31 to the first wind-resistant frame 32 through the first vertical cable 310, and the second side of the first wind-resistant frame 32 can be arched toward the direction close to the first side to form an escape space 33 for facilitating the arching of the wind-resistant cable 31, thereby limiting the vertical displacement of the first wind-resistant frame 32 due to wind suction and wind lifting, the space utilization rate under the photovoltaic assembly of the flexible photovoltaic support can be improved, and the span of the flexible photovoltaic support can be increased.

[0061] The flexible photovoltaic bracket disclosed in the embodiment of the present application is configured such that the second side of the first wind-resistant frame 32 is arched toward the first side to form an avoidance space 33 for facilitating the arching of the wind-resistant cable 31. This can improve the space utilization rate below the photovoltaic components of the flexible photovoltaic bracket while limiting the vertical displacement of the first wind-resistant frame 32 caused by wind suction and wind lifting, and increase the span of the flexible photovoltaic bracket, thereby realizing the advantages of the large span and large clearance of the flexible photovoltaic bracket.

[0062] like Figure 1 As shown, the wind-resistant assembly 300 may also include a second wind-resistant frame 34, and the second wind-resistant frame 34 has upper and lower sides arranged relatively to each other. For the convenience of understanding, the upper and lower sides of the second wind-resistant frame 34 are defined as a first side and a 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 through a second vertical cable 340, so as to limit the second wind-resistant frame 34 from being vertically displaced by wind suction and wind lifting, thereby improving the wind-resistant performance of the flexible photovoltaic support.

[0063] like Figure 4 As shown, the second wind-resistant frame 34 may include at least one plane wind-resistant frame 341, and the plane wind-resistant frame 341 may include a second upper chord 3410, a second lower chord 3411, and a second connecting rod 3412, and the second upper chord 3410 is arranged in parallel with the second lower chord 3411, and the second lower chord 3411 is located below the second upper chord 3410. At the same time, the two ends of the second upper chord 3410 are respectively connected to the two ends of the second lower chord 3411 through the second connecting rod 3412 to form a plane truss system.

[0064] In order to improve the overall stability of the second wind-resistant frame 34, Figure 4 As shown, the second wind-resistant frame 34 may include two planar wind-resistant frames 341. Exemplarily, the two planar wind-resistant frames 341 may be arranged in parallel along the extension direction of the main cable 11, or may be arranged at a certain angle along the extension direction of the main cable 11, and the two planar wind-resistant frames 341 may be connected by a connecting rod, and each connecting rod may be arranged in parallel or crosswise, or the second upper chords 3410 of the two planar wind-resistant frames 341 are connected by a connecting rod, and the second lower chords 3411 of the two planar wind-resistant frames 341 are connected by a connecting rod, and the connecting rod connecting the second upper chord 3410 and the connecting rod connecting the second lower chord 3411 may be crosswise or parallel.

[0065] Preferably, if Figure 4As shown, the two plane wind-resistant frames 341 are arranged to form a certain angle along the extension direction of the main cable 11, and the two plane wind-resistant frames 341 can share a second lower chord rod 3411, that is, the second lower chord rod 3411 can be located directly below the central axis of the two planes where the second upper chord rods 3410 of the two plane wind-resistant frames 341 are located, and one end of the second connecting rod 3412 of the two plane wind-resistant frames 341 is respectively connected to the end of the second upper chord rod 3410 of the two plane wind-resistant frames 341, and the other end of the second connecting rod 3412 of the two plane wind-resistant frames 341 is respectively connected to the end of the second upper chord rod 3410 of the two plane wind-resistant frames 341. One end intersects with 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 links 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 links 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 space truss structure, thereby improving the overall stability of the second wind-resistant frame 34 while reducing the number of rods and saving costs.

[0066] Of course, in the above embodiment, the two planar wind-resistant frames 341 may also share a second upper chord 3410, so that the second wind-resistant frame 34 is a regular triangular cone space truss structure, which will not be described in detail herein.

[0067] In order to improve the wind resistance and stability of flexible photovoltaic brackets, such as Figure 1 As shown, the wind-resistant assembly 300 may also include at least one stabilizing cable 35, and the stabilizing cable 35 is located below the main cable 11, and both ends of the stabilizing cable 35 are respectively fixed to the supporting 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, respectively, so as to form an integral spatial structure, thereby improving the overall stability of the flexible photovoltaic support, effectively resisting the distortion and collision of the photovoltaic assembly caused by wind load, snow load and gravity load, reducing the risk of damage to the photovoltaic assembly due to wind force, and reducing the risk of hidden cracks and flipping of the photovoltaic assembly.

[0068] For example, Figure 1 , Figure 3 and Figure 5As shown, the stabilizing cable 35 may be used but not limited to one, and may also be used in two, three, four or more, to improve the overall stability of the flexible photovoltaic support. Preferably, two stabilizing cables 35 may 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 the cable connector 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 the cable connector 36, thereby forming a four-cable spatial cage structure, thereby improving the overall stability of the flexible photovoltaic support.

[0069] For example, Figure 3 , Figure 5 and Fig.13 As shown, the cable connector 36 may include a base 360 ​​and a U-shaped lock 361 matched with the base 360, and a penetration area is formed between the U-shaped lock 361 and the base 360. When connecting the first upper chord rod 320, the second upper chord rod 3410 and the main cable 11, the main cable 11 is passed through the penetration area of ​​the U-shaped lock 361, and the two ends of the U-shaped lock 361 are sequentially passed through the two through holes opened on the end of the first upper chord rod 320 or the second upper chord rod 3410 and the mounting hole of the base 360, and after the washers 362 are sleeved on the two ends of the U-shaped lock 361, the nuts 363 are used to threadably match the two ends of the U-shaped lock 361 until the first upper chord rod 320, the second upper chord rod 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 lock buckle 361, and the two ends of the U-shaped lock buckle 361 are passed 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 turn, and washers 362 are sleeved on both ends of the U-shaped lock buckle 361, and nuts 363 are used to cooperate with the threads of the two ends of the U-shaped lock buckle 361 until the first lower chord 321, the second lower chord 3411 and the stabilizing cable 35 are locked.

[0070] Since 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 position of two adjacent supporting structures 200, and one or more second wind-resistant frames 34 can be respectively set on both sides of the first wind-resistant frame 32, so as to save costs while meeting the wind resistance and mechanical properties of the flexible photovoltaic bracket, and at the same time ensure a larger clearance height under the photovoltaic component, improve the space utilization of the flexible photovoltaic bracket, and increase the span of the flexible photovoltaic bracket, thereby realizing the advantages of large span and large clearance of the flexible photovoltaic bracket.

[0071] In order to maximize the power generation efficiency of the flexible photovoltaic system, Figure 1As shown, the flexible photovoltaic support may further include a driving assembly 400, and the driving assembly 400 may include a beam assembly 41 and a driving member 42. The beam assembly 41 is rotatably connected to the support structure 200, and both ends of the main cable assembly 100 and the stabilizing cable 35 are respectively fixed on the beam assembly 41, and the driving member 42 is transmission-connected to the beam assembly 41 to drive the beam assembly 41 to rotate, so as to adjust the angle of the photovoltaic assembly and maximize the power generation efficiency of the flexible photovoltaic system.

[0072] At the same time, if 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 act, 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, so that the first vertical cable 310 and the second vertical cable 340 can only play a vertical restraining role on the first wind-resistant frame 32 and the second wind-resistant frame 34, and no additional torque will be generated due to the rotation of the first wind-resistant frame 32 and the second wind-resistant frame 34.

[0073] For example, Figure 3 As shown, there can be two first vertical cables 310, and they are respectively connected to the rotation center of the midpoint of the first upper chord 320 of the first wind-resistant frame 32. One end of the first vertical cable 310 can be connected to the pin shaft passing through the midpoint of the first upper chord 320, and the other end of the first vertical cable 310 can be connected to the wind-resistant cable 31 through a U-shaped shackle. Figure 5 As shown, there can be two second vertical cables 340, and one end of the two second vertical cables 340 is respectively connected to the rotation center of the midpoint position of the two second upper chords 3410 of the second wind-resistant frame 34 through a U-shaped shackle, and the other end of the two second vertical cables 340 is respectively connected to the wind-resistant cable 31 through a cable connector 36.

[0074] like Figure 1 As shown, the support structure 200 may include an end bracket 21. Figure 6 As shown, the end bracket 21 may include an end support structure 210, an end mounting frame 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 frame 211 may be fixed to the top of the end support structure 210. Figure 6 and Figure 8As shown, the end mounting frame 211 may include two end mounting plates 2110 arranged at intervals, and each end mounting plate 2110 is provided with an integrally bent ear plate 2111, and the inclined cable 23 may be connected and fixed to the ear plate 2111 without being restricted by the quality of the weld, which can ensure the transmission and stability of force, and the clamps and other mounting parts required for connecting the inclined cable 23 with the end support structure 210 can be omitted, which can reduce the installation process, simplify the structure of the end bracket 21, and realize the rapid installation of the end bracket 21, thereby forming a stable inclined cable 23 support system. At the same time, the driving assembly 400 can be installed on one side of the end mounting frame 211 to drive the photovoltaic assembly on the main cable assembly 100 to rotate, so as to adapt to the irradiation of different altitude angles of the sun and maximize the power generation efficiency of the flexible photovoltaic system.

[0075] For example, Figure 8 As shown, the end mounting plate 2110 can adopt a right-angle 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. At the same time, the ear plate 2111 is arranged 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 directions away from each other, so that a preset angle is formed between the ear plate 2111 and the end mounting plate 2110, thereby forming a stable triangular system. Optionally, the preset angle between the ear plate 2111 and the end mounting plate 2110 can be 135° to 170°, so that an angle of 20° to 90° can be formed between the two inclined cables 23 connected to the ear plate 2111, thereby improving the transmission efficiency of the tension of the inclined cables 23 and enhancing the stability out of the plane.

[0076] like Figure 6 As shown, one end of the inclined cable 23 can be connected to the ear plate 2111 through a connecting piece 24, and the other end of the inclined cable 23 is connected to the fixing seat 25 through a U-shaped buckle 26. At the same time, the fixing seat 25 can be fixed to the upper surface of the pile foundation by fasteners such as bolts, or the fixing seat 25 can also be pre-buried in the pile foundation to achieve the connection and fixation between the fixing seat 25 and the pile foundation, thereby forming a supporting system for the inclined cable 23.

[0077] For example, Figure 6As shown, the connector 24 may be a cylindrical structure, and the connector 24 may be formed with a slot 240 plugged into the ear plate 2111, and the two side walls of the slot 240 are correspondingly provided with a first mounting hole, and a second mounting hole matching the first mounting hole is provided on the ear plate 2111. When the slot 240 of the connector 24 is inserted into the ear plate 2111, the first mounting hole is aligned with the second mounting hole, and at this time, the connector 24 and the ear plate 2111 can be connected and fixed by a pin passing through the first mounting hole and the second mounting hole. It should be noted that the connector 24 and the inclined cable 23 can be connected and fixed by welding or threading to achieve the connection and fixation between the connector 24 and the inclined cable 23.

[0078] In order to ensure a reliable connection between the end mounting frame 211 and the end support structure 210, as Figure 6 and Figure 8 As shown, the end mounting frame 211 may also include an end connecting plate 2116 connected to the end supporting structure 210, and the end mounting plate 2110 is welded to the end connecting plate 2116 to ensure that there is a larger connection area between the end mounting frame 211 and the end supporting structure 210, thereby improving the reliability of the connection between the end mounting frame 211 and the end supporting structure 210.

[0079] Exemplarily, the end connecting plate 2116 can be fixed to the upper surface of the end supporting structure 210 by fasteners such as bolts, or the end connecting plate 2116 can be pre-buried in the end supporting structure 210, thereby ensuring a reliable connection between the end connecting plate 2116 and the end supporting structure 210. It should be noted that the end connecting plate 2116 can be circular, square, etc., and the specific shape can be determined according to the cross-sectional shape of the end supporting structure 210.

[0080] like Figure 1 and Figure 6 As shown, the beam assembly 41 may include an end rotating beam 411 connected to the main cable assembly 100 and the stabilizing cable 35, and the driving member 42 may include an end driving device 421 for driving the end rotating beam 411 to rotate, the end rotating beam 411 and the end driving device 421 are both located on one side of the end mounting frame 211, and the end rotating beam 411 and the end driving device 421 are connected via an end flange plate 4113.

[0081] In order to facilitate the connection between the end drive device 421 and the end mounting frame 211, as shown in FIG. Figure 6 and Figure 8 As shown, the end mounting frame 211 may further include an end fixing plate 2112 detachably connected to the end driving device 421 , and the end fixing plate 2112 may be fixed between the two end mounting plates 2110 by welding.

[0082] For example, 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, the end fixing plate 2112 and the ear plate 2111 are both located on the side of the end mounting plate 2110 close to the end driving device 421 (the right-angle side of the end mounting plate 2110), and an avoidance notch 2113 is formed on the end fixing plate 2112 to avoid the ear plate 2111, so that the end fixing plate 2112 has a T-shaped structure, thereby avoiding the problem that the end fixing plate 2112 cannot be installed due to the size deviation between the end mounting plate 2110 and the ear plate 2111 when installing the end fixing plate 2112. The upper area of ​​the avoidance notch 2113 of the end fixing plate 2112 can be fixed to the end mounting plate 2110 by welding. In addition, as Figure 8 As shown, a plurality of fixing holes for installing the end drive device 421 are distributed in a ring in the upper area of ​​the avoidance 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.

[0083] like Figure 8 As shown, the ear plate 2111 may have an upturned end 2111 - 1 facing away from the end support structure 210 , so that the inclined cable 23 can be connected to the upturned end 2111 - 1 of the ear plate 2111 through the connecting member 24 , thereby avoiding interference with the end support structure 210 .

[0084] For example, Figure 8 As shown, the raised end 2111-1 can be raised upward by 45°, that is, the angle between the raised end 2111-1 and the upper surface of the end support structure 210 can be 45°, so that the inclined cable 23 can be connected to the raised end 2111-1 of the ear plate 2111 through the connecting piece 24, so that the end support structure 210 can effectively avoid the connection between the inclined cable 23 and the ear plate 2111 through the connecting piece 24.

[0085] like Figure 8 As shown, an inner recess 2111 - 2 for avoiding the rotation of the end rotating beam 411 may be formed at the connection position between the ear plate 2111 and the end mounting plate 2110 , thereby allowing the end rotating beam 411 to have a larger rotation angle and avoiding interference with the ear plate 2111 .

[0086] For example, Figure 8 As shown, the ear plate 2111 is tilted at the connection position with the end mounting plate 2110 toward the upward end 2111-1 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.

[0087] In order to ensure the reliability of the connection between the end fixing plate 2112 and the end mounting plate 2110, as shown in FIG. Figure 8 As shown, a plurality of reinforcing partitions 2114 may be provided between the two end mounting plates 2110 to reinforce the end mounting plates 2110 and improve the stability of the end mounting plates 2110 to ensure the overall stability of the end mounting frame 211. Meanwhile, at least one reinforcing partition 2114 abuts against the lower side of the end fixing plate 2112 to support the end fixing plate 2112, thereby reducing the pressure of the weld connecting the end fixing plate 2112 and the end mounting plate 2110, and at the same time improving the overall stability of the end mounting frame 211.

[0088] For ease of understanding, the reinforcing partition 2114 abutting against the lower side of the end fixing plate 2112 is defined as a supporting partition 2115. Fig. 9 As shown, the support partition 2115 may include a variable width section and an equal width section, wherein the variable width section has a small width end and a large width end, and the width of the variable width section gradually increases from the small width end toward the large width end. The equal width section is connected to the small width end of the variable width section, so that the equal width section can adapt to the width between the two end mounting plates 2110, and the variable width of the variable width section can adapt to the width between the two ear plates 2111 bent in directions away from each other, so as to ensure the reliability of the connection between the support partition 2115 and the end mounting frame 211, improve the overall stability of the end mounting frame 211, and at the same time, provide a better support effect on the end fixing plate 2112, and reduce the pressure of the welding seam connecting the end fixing plate 2112 and the end mounting plate 2110.

[0089] Of course, the end fixing plate 2112 can also directly extend to the end connecting plate 2116 and be welded and fixed to the end connecting plate 2116. At the same time, the two sides of the end fixing plate 2112 are respectively welded and fixed to the two end mounting plates 2110, and two, three or more reinforcing partitions 2114 can be arranged between the two end mounting plates 2110 to improve the overall stability of the end mounting frame 211.

[0090] In order to ensure that the welds between the support partition 2115, the end mounting plate 2110 and the ear plate 2111 remain continuous, as shown in FIG. Figure 8 As shown, a welding notch 2117 may be provided on the lower side of the end fixing plate 2112, thereby ensuring that the welds between the support baffle 2115, the end mounting plate 2110 and the ear plate 2111 remain continuous and will not be disconnected by the end fixing plate 2112. At the same time, it is convenient for the welding gun to be inserted into the welding notch 2117 to perform welding between the support baffle 2115, the end mounting plate 2110 and the ear plate 2111 during welding, thereby improving welding efficiency and welding quality.

[0091] Exemplarily, the two corners on the lower side of the end fixing plate 2112 may be provided with 45° inclined chamfers to form welding notches 2117 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 supporting partition 2115 and the end mounting plate 2110 and the ear plate 2111 remain continuous, thereby improving welding efficiency and welding quality.

[0092] like Figure 6 As shown, the end driving device 421 may include an end horizontal reducer 4210 and an end driving motor 4211 driving the end horizontal reducer 4210. The end horizontal reducer 4210 may be connected to the end rotating beam 411 through an end flange plate 4113, and the end horizontal reducer 4210 is connected and fixed to the end fixing plate 2112 through fasteners such as bolts.

[0093] For example, 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 close to the end mounting frame 211, and the end horizontal reducer 4210 can be connected to the end flange plate 4113 by bolts and other fasteners. At the same time, the end rotating beam 411 has two connecting surfaces 4110 arranged opposite to each other, namely the top surface and the bottom surface of the end rotating beam 411, and a plurality of end reinforcing ribs 4111 connected to the end flange plate 4113 are arranged on each connecting surface 4110, that is, the end reinforcing ribs 4111 can be two, three or more, and the end reinforcing ribs 4111 can adopt a triangular structure, so 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 , thereby reinforcing the weld connection between the end flange plate 4113 and the end rotating beam 411, and at the same time, the end reinforcing ribs 4111 on the two connecting surfaces 4110 of the end rotating beam 411 can also play a role of upper and lower constraints between the end rotating beam 411 and the end flange plate 4113, and further play a role of upper and lower constraints between the end rotating beam 411 and the end horizontal reducer 4210, so that when the end rotating beam 411 is subjected to an unbalanced overturning force, the stability of the connection between the end rotating beam 411 and the end horizontal reducer 4210 can be improved.

[0094] like Fig.10As shown, the main cable 11 and the stabilizing cable 35 can be respectively fixed to the two connecting surfaces 4110 of the end rotating cross beam 411 through the end cable clamp 4112. Under the prestress of the four cables, the force between the end horizontal reducer 4210 and the end fixing plate 2112 is compressed, and 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 compression role, which can avoid the key weld from forming an unfavorable tensile force form.

[0095] For example, Figure 7 and Fig.10 As shown, the end cable clamp 4112 may include a clamp connection plate, and the clamp connection plate is welded to the side of the end rotating beam 411 away from the end mounting frame 211, and through holes for passing the main cable 11 and the stabilizing cable 35 are respectively provided on the clamp connection plate, so that the main cable 11 and the stabilizing cable 35 can pass through the through holes of the clamp connection plate and then be locked and fixed by the end head. In addition, a reinforcing plate connected to the clamp connection plate can be welded on the two connecting surfaces 4110 of the end rotating beam 411, and the reinforcing plate can adopt a triangular structure, so that one side of the reinforcing plate can be welded to the connecting surface 4110 of the end rotating beam 411, and the other side of the reinforcing plate can be welded to the clamp connection plate, so that the weld connection between the clamp connection plate and the end rotating beam 411 can be reinforced.

[0096] When the span of the flexible photovoltaic bracket is large, such as Figure 1 As shown, the support structure 200 may also include a middle bracket 22. Fig.11 and Fig.12 As shown, the middle bracket 22 may include a middle support structure 220 and a middle mounting frame 221 disposed on the middle support structure 220. The middle support structure 220 may be a foundation structure such as a concrete pile foundation or a steel structure column, and the middle mounting frame 221 may be fixed to the top of the middle support structure 220. The middle mounting frame 221 may include a pipe body 2210 and a middle mounting plate 2212 connected to the pipe body 2210 by welding. At the same time, the crossbeam assembly 41 may also include a middle rotating crossbeam 412 connected to the main cable assembly 100 and the stabilizing cable 35 through a middle cable clamp 4120, and the driving member 42 may also include a middle driving device 422 for driving the middle rotating crossbeam 412 to rotate, and the middle driving device 422 may be installed on the middle mounting plate 2212 by fasteners such as bolts.

[0097] For example, Fig.11 and Fig.12As shown, the middle cable holder 4120 may include a pressure plate, and the pressure plate is arched in a direction away from the middle rotating beam 412 to form a space for the main cable 11 or the stabilizing cable 35 of the main cable assembly 100 to pass through, and the pressure plate is connected and fixed to the middle rotating beam 412 by fasteners such as bolts. When the main cable 11 and the stabilizing cable 35 pass through the top and bottom surfaces of the middle rotating beam 412 respectively, the main cable 11 and the stabilizing cable 35 can be fixed to the top and bottom surfaces of the middle rotating beam 412 respectively by the pressure plate, so that the middle driving device 422 can drive the middle rotating beam 412 to rotate, so as to drive the photovoltaic assembly on the main cable assembly 100 to rotate.

[0098] Since the horizontal tension in the span of the flexible photovoltaic bracket is small, Fig.11 As shown, the middle driving device 422 may include a middle vertical reducer 4220 and a middle driving motor 4221 driving the middle vertical reducer 4220, thereby saving costs. The middle rotating crossbeam 412 and the middle vertical reducer 4220 are connected through a middle flange plate 4121, and the middle rotating crossbeam 412 is located between the middle vertical reducer 4220 and the middle flange plate 4121, and the middle vertical reducer 4220 and the middle flange plate 4121 are connected and fixed by fasteners such as bolts.

[0099] In order to ensure the reliable connection between the middle mounting frame 221 and the middle supporting structure 220, as Fig.11 As shown, the middle mounting frame 221 may also include a middle connecting plate 2213 connected to the middle supporting structure 220, and the tube body 2210 is welded to the middle connecting plate 2213. At the same time, a plurality of middle reinforcing ribs 2211 are arranged on the outer side of the tube body 2210 to ensure that there is a larger connection area between the middle mounting frame 221 and the middle supporting structure 220, thereby improving the reliability of the connection between the middle mounting frame 221 and the middle supporting structure 220.

[0100] For example, Fig.11 As shown, the tube body 2210 can be a square steel tube, and a central reinforcing rib 2211 is arranged around the tube body 2210 to ensure a large connection area between the central mounting frame 221 and the central support structure 220. At the same time, the central connecting plate 2213 can be fixed to the upper surface of the central support structure 220 by fasteners such as bolts, or the central connecting plate 2213 can also be pre-buried in the central support structure 220, so as to ensure 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.
