[0050] Flexible photovoltaic support system is an indispensable part of photovoltaic power generation system, which provides support and fixation for photovoltaic modules. Compared with traditional rigid photovoltaic support, flexible support has higher adaptability and flexibility, which can adapt to complex and variable terrain conditions, reduce land use and improve the installed capacity of photovoltaic power station.

[0051] However, the existing flexible photovoltaic support has some limitations in the connection and fixation between the cable structure and the support structure. Usually, the fixing part adopts an integrated design, which means that during installation, the through hole on the fixing part must be passed through the cable structure (such as steel cable) first, and then the subsequent installation work can be carried out. The installation process is relatively complex, which increases the installation time and cost.

[0052] To solve the problems in the prior art, the present application provides a flexible support fixing member, which can simplify the installation process of the support and the replacement of the fixing member, improve the work efficiency, and also be conducive to reducing the operation and maintenance cost.

[0053] In one embodiment, reference is made to the drawings attached to the specification Figures 1 to 3The flexible support fixing component provided in this application is mainly used for connecting and fixing the support structure 1 and the cable structure 2 of a flexible photovoltaic support. The fixing component mainly includes a lifting ring body 3, a first fixing component 4 and a second fixing component 5. The lifting ring body 3 has an opening to facilitate the installation of the cable structure 2, and the lifting ring body 3 has two opposite ends on one side of the opening.

[0054] The first fixing component 4 includes a first limiting part and a first connecting part. The first limiting part is at least partially located in the opening of the lifting ring body 3, and the first connecting part is used to connect the support structure 1. The second fixing component 5 connects the first limiting part and the two ends of the lifting ring body 3. The lifting ring body 3, the first limiting part, and the second fixing component 5 together form a first installation space 500, which is used to limit the position of the cable structure 2 and ensure its stable fixation.

[0055] Furthermore, the first installation space 500 allows the cable structure 2 to maintain a certain degree of mobility while remaining connected, adapting to different stress conditions. The first installation space 500 can be achieved through an adjustable locking mechanism. For example, the range of motion of the cable structure 2 can be controlled by adjusting the tightness of the bolts, allowing for either complete locking or a degree of movement to accommodate different installation and usage requirements. Of course, elastic elements, such as springs, can be added to the first installation space 500 to provide elastic support, allowing the cable structure 2 some room for expansion and contraction under external forces, reducing stress concentration and improving the system's stability and durability.

[0056] Based on the content of this embodiment, furthermore, by setting the first connecting part, an adjustable mounting position 400 can be formed on the first fixing component 4, which can adapt to support structures 1 of different sizes and achieve quick locking.

[0057] It should be noted that the mounting position 400 is formed by the first fixing component 4 to lock the support structure 1 onto the first fixing component 4, so that the support structure 1 can remain stable. Furthermore, since the mounting position 400 is adjustable, the fixing component can adapt to different installation requirements.

[0058] In one embodiment, the lifting ring body 3 includes a second limiting part 31 and two second connecting parts 32. The second limiting part 31 has a U-shaped profile, and the two second connecting parts 32 are located at the two ends of the lifting ring body 3, respectively. The two second connecting parts 32 are detachably connected to the second fixing component 5, allowing the lifting ring body 3 to be easily removed from the first fixing component 4. The detachable connection between the lifting ring body 3 and the fixing component significantly improves the flexibility and ease of maintenance of the fixing component. Compared with traditional one-piece fixing components, the detachable connection in this embodiment allows the lifting ring body 3 to be easily removed without damaging any parts when the fixing component needs to be replaced or maintained, reducing material waste and maintenance costs. Specifically, users can easily remove the lifting ring body 3 from the cable structure 2 directly through the opening on the lifting ring body 3 without complicated tools or additional operations. This not only simplifies the disassembly process but also reduces the risk of damage caused by improper disassembly, further improving the safety and convenience of maintenance work.

[0059] The two second connecting parts 32 are connected to the second fixing component 5 at the same time, which increases the contact area between the lifting ring body 3 and the second fixing component 5, allowing for a more even distribution of force, reducing local stress concentration, and extending the service life of the fixing component.

[0060] Furthermore, the second limiting part 31 has a smooth surface. This design is primarily used to reduce friction or collision with the cable structure 2, thereby protecting the cable structure 2 from damage and extending the service life of both. Understandably, under the influence of wind or other external forces, the cable structure 2 may move relative to the second limiting part 31. If the contour of the second limiting part 31 is not smooth, it can easily cause wear on the cable structure 2, thus affecting the structural stability of the flexible support. In actual production, optionally, the second limiting part 31 can undergo mechanical polishing, chemical polishing, or electrochemical polishing to achieve a smooth surface.

[0061] Based on the above embodiments, the second limiting part 31 of the lifting ring body 3 is made of steel. Utilizing the high strength and good mechanical properties of steel, the stability and durability of the lifting ring body 3 during use are ensured. The outer surface of the lifting ring body 3 is covered with a polymer material. This material has good chemical stability and weather resistance, effectively resisting the erosion of ultraviolet rays, moisture, and chemicals. Furthermore, the polymer material has a low coefficient of friction, which helps reduce friction between the lifting ring body 3 and the cable structure 2, reducing wear, improving system operating efficiency, and extending the service life of the lifting ring body 3 to a certain extent.

[0062] In one embodiment, the first fixing component 4 includes a first connecting bolt 41 and a first connecting nut 42. The head of the first connecting bolt 41 serves as a first limiting part of the first fixing component 4, and the bolt body of the first connecting bolt 41 serves as a first connecting part of the first fixing component 4. In the installed state, the first connecting bolt 41 passes through the support structure 1 and is connected with the first connecting nut 42.

[0063] The first connecting bolt 41 is a key component of the first fixing assembly 4, and its size and thread specifications are selected according to the thickness and material properties of the support structure 1. Understandably, based on this embodiment, when the support structure 1 needs to be replaced or maintained, it can be quickly disassembled simply by loosening the first connecting nut 42, making maintenance convenient and quick. Simultaneously, when the clamping force needs to be adjusted, the operator only needs to tighten the first connecting nut 42, adjusting the distance between the head of the first connecting nut 42 and the head of the first connecting bolt 41 to control the clamping force of the support structure 1.

[0064] Furthermore, placing a washer between the first connecting nut 42 and the first connecting bolt 41 prevents the head of the first connecting nut 42 or the first connecting bolt 41 from directly contacting the support structure 1, reducing the risk of friction and scratches. In practical applications, flat washers or elastic washers can be selected. Flat washers increase the contact area, distributing the load of the first connecting bolt 41 or the first connecting nut 42 evenly on the surface of the support structure 1, reducing local pressure. Elastic washers, after the bolts and nuts are tightened, increase axial tension due to their own reaction force, thereby increasing friction and preventing loosening. In some applications, flat washers and elastic washers can be used in combination to provide additional protection and adjustment space, protecting the support structure 1 from damage while mitigating vibration through the elastic properties of the elastic washer, and preventing loosening of the connection.

[0065] Based on the above embodiments, please refer to the appendix to the specification. Figure 3 The two second connecting parts 32 of the lifting ring body 3 are simultaneously connected to the head of the first connecting bolt 41 through the second fixing component 5 to achieve relative fixation between the lifting ring body 3 and the first fixing component 4.

[0066] In this embodiment, the double fixing by the two second connecting parts 32 significantly improves the stability of the entire structure and reduces displacement or deformation caused by external forces. When adjustment or maintenance is required, the second fixing component 5 can be quickly disassembled, facilitating inspection and maintenance of the lifting ring body 3 and the first fixing component 4.

[0067] Furthermore, the relative distance between the two second connecting portions 32 is at least equal to the radial dimension of the head of the first connecting bolt 41, ensuring that when the lifting ring body 3 is connected to the first fixing component 4, the head of the first connecting bolt 41 can be located between the two second connecting portions 32. Thus, the second limiting portion 31 and the head of the first connecting bolt 41 together form a first installation space 500 adapted to the cable structure 2.

[0068] In one embodiment, the head of the first connecting bolt 41 is configured as a spherical head 410, such that the contact between the spherical head 410 of the first connecting bolt 41 and the support structure 1 is concentrated in a small area of ​​the spherical surface. Compared with planar contact, this design greatly reduces the contact area, thereby reducing contact stress and friction, and reducing the risk of wear and damage.

[0069] Additionally, it is understandable that a threaded hole adapted to the first connecting bolt 41 will be provided on the support structure 1, and a portion of the spherical head 410 abuts against the opening of the bolt hole. Because the spherical profile of the spherical head 410 provides a spherical contact surface, the spherical head 410 can maintain a certain amount of movement, allowing the first connecting bolt 41 to rotate slightly to accommodate minor adjustments required due to installation or manufacturing errors.

[0070] Optionally, the surface of the spherical head 410 can be polished or coated to further improve its wear resistance and reduce friction.

[0071] Furthermore, such as Figure 3 As shown, the spherical head 410 has a first end face 4101, which is an arc surface concave towards the center of the spherical head 410. This arc surface structure allows the spherical head 410 to form a good fit with the outer contour of the cable structure 2. Understandably, in use, a portion of the cable structure 2 can be embedded in the first end face 4101. At this time, the spherical head 410 not only serves as a connection point but also provides a limit for the cable structure 2, preventing excessive displacement or rotation of the cable structure 2 under stress, thus enhancing the stability of the entire structure.

[0072] In one embodiment, based on the above embodiments, the second fixing component 5 includes a second connecting bolt 51 and a second connecting nut 52.

[0073] Specifically, the heads of the two second connecting parts 32 and the first connecting bolt 41 are provided with assembly holes, so that the second connecting bolt 51 can pass through the assembly holes of the two second connecting parts 32 and the head of the first connecting bolt 41 at the same time, and connect with the second connecting nut 52 to achieve relative fixation between the lifting ring body 3 and the first fixing component 4.

[0074] Understandably, the various parts of the fixing components, such as the first fixing component 4, the second fixing component 5, and the lifting ring body 3, are all detachable, making it more convenient to maintain and replace parts without having to destructively dismantle the entire structure, thereby reducing maintenance costs and facilitating the reuse of parts.

[0075] In this embodiment, the lifting ring body 3 can rotate around the second connecting bolt 51 as the axis under the action of external force. In other words, the lifting ring body 3 can rotate within a certain range to adapt to different installation angles and adjustment needs, and can match the specific position and orientation of the cable structure 2.

[0076] Meanwhile, each second connecting part 32 is spaced at a preset distance from the head of the first connecting bolt 41 to prevent the lifting ring body 3 from rubbing or colliding with the head of the first connecting bolt 41 during rotation, thereby protecting the integrity of the component and extending its service life.

[0077] Based on the above embodiments, the end face of each second connecting part 32 near the second fixing component 5 is designed as a planar structure. When the second connecting part 32 is connected to the second connecting bolt 51 and the second connecting nut 52, the planar end face of the second connecting part 32 is flush with the mating end face of the second connecting bolt 51 and the second connecting nut 52, providing a stable contact surface. This allows for even distribution of stress at the connection, which helps improve the stability and reliability of the connection and reduces the risk of connection failure due to stress concentration.

[0078] In one embodiment, refer to the appendix to the specification. Figure 1 , Figure 4 and Figure 6 According to another aspect of this application, a flexible photovoltaic (PV) bracket is further provided, mainly comprising at least two support columns 62, a support structure 1, a cable structure 2, and a plurality of the aforementioned flexible bracket fixing components. The support columns 62 are spaced apart, forming the basic structure of the flexible PV bracket. The cable structure 2 extends along the arrangement direction of the support columns 62 and is connected at both ends to the corresponding support columns 62. The cable structure 2 includes two parallel load-bearing cables 21 and a stabilizing cable 22 located below the load-bearing cables 21. The ends of the load-bearing cables 21 and the stabilizing cables 22 are connected to the corresponding support columns 62. PV modules 61 are correspondingly installed on the load-bearing cables 21. The support structure 1 is located between the load-bearing cables 21 and the stabilizing cables 22, enabling the support structure 1 to evenly distribute the weight load of the PV modules 61, reducing the load on individual load-bearing cables 21, thereby extending their service life and reducing maintenance costs.

[0079] Among them, the support structure 1 and the cable structure 2 are connected by these flexible bracket fixing components, thereby connecting the load-bearing cable 21 and the stabilizing cable 22 through the support structure 1, improving the stability and wind resistance of the flexible photovoltaic bracket. Specifically, the load-bearing cable 21 can directly bear the weight of the photovoltaic module 61, while the stabilizing cable 22 provides additional stability for the entire structure. Especially under the action of wind, the stabilizing cable 22 can effectively prevent the structure from overturning.

[0080] Compared with some existing technologies where cable structures 2 need to pass through a lifting ring structure before installation, this embodiment uses the above-mentioned flexible support fixing component. The split and detachable design of the fixing component makes the overall installation and construction of the support more convenient and simple.

[0081] At the start of installation, cable structure 2 is first tensioned to ensure it extends in the preset direction and maintains appropriate tension. After cable structure 2 is tensioned, lifting ring bodies 3 are sequentially fitted onto cable structure 2. If it is found during installation that the number of fixing components needs to be increased or decreased to accommodate different support requirements or design changes, simply add or remove the excess lifting ring bodies 3 from cable structure 2 accordingly, improving construction efficiency and reducing material waste.

[0082] In one embodiment, the support structure 1 includes a frame body 11 and a plurality of support rods 12, and the load-bearing cable 21 is connected to the frame body 11 through a flexible bracket fixing member.

[0083] Furthermore, one end of several support rods 12 is connected to the stabilizing cable 22 via a connector (or a flexible bracket fixing component), and the other end is connected to the frame body 11 via the first fixing component 4 of the flexible bracket fixing component, thereby achieving relative fixation between the stabilizing cable 22 and the supporting structure 1, and further forming a connection between the stabilizing cable 22, the supporting structure 1, and the load-bearing cable 21.

[0084] like Figure 2 As shown, in this embodiment, the first fixing component 4 connects both the frame body 11 and the support rod 12. The first fixing component 4 is configured using the combination of the first connecting bolt 41 and the first connecting nut 42 described above. Specifically, the first connecting bolt 41 is aligned with the preset holes at the ends of the frame body 11 and the support rod 12, and passes through both ends of the frame body 11 and the support rod 12. The connection and fixing are then achieved by tightening the first connecting nut 42. However, in other embodiments, the first fixing component 4 can also adopt other forms, such as clamp connection or other mechanical connection methods.

[0085] Based on the content of the above embodiments, in one embodiment, such as Figure 5As shown, the frame body 11 includes several load-bearing rods 111, which are connected end to end and integrally formed, so that the frame body 11 forms a polygonal structure. The connection points of several support rods 12 to the frame body 11 are located at different ends of the polygonal structure. The integral structure ensures the integrity and strength of the structure, and avoids the need to assemble several load-bearing rods 111 on the construction site, simplifying the workflow and saving installation time.

[0086] It should be noted that there are typically three load-bearing rods 111, which, together with three support rods 12, form a triangular pyramid structure for the support structure 1. As one of the most stable geometric shapes, the triangle allows the triangular pyramid structure to evenly distribute stress when facing wind and other external forces, reducing localized stress concentration and ensuring structural stability. Besides a triangular structure, the frame body 11 can also be designed as a quadrilateral, pentagonal, or more-sided structure, and the support structure 1 can then correspond to a quadrilateral pyramid, pentagonal pyramid, or other polygonal pyramid structure to adapt to different application scenarios and load requirements. In summary, the pyramidal structure formed by the frame body 11 and the support rods 12 can provide higher load-bearing capacity and stability within a limited space.

[0087] Optionally, the load-bearing rod 111 adopts a rectangular tube cross section, which improves the stability of the connection to a certain extent.

[0088] In addition, the two load-bearing cables 21 extend in parallel directions, and each load-bearing cable 21 is connected to the support structure 1 through one or more flexible support fixing components. Taking the frame body 11 as a triangular structure (the support structure 1 is a triangular pyramid) as an example, the frame body 11 has three connection points. Then, of the two load-bearing cables 21, one load-bearing cable 21 passes through two of the connection points at the same time, and the other load-bearing cable 21 passes through the remaining connection point to form a connection between the load-bearing cable 21 and the frame body 11.

[0089] In one embodiment, according to another aspect of this application, such as Figure 6 As shown, this application also provides a flexible photovoltaic support system, which includes multiple rows of the aforementioned flexible photovoltaic supports and a first wind-resistant component. The first wind-resistant component is sequentially connected to the support structure 1 of adjacent rows of flexible photovoltaic supports to form a connection of multiple rows of flexible photovoltaic supports. This design effectively disperses wind force throughout the entire structure, reduces local stress concentration, and improves the stability and reliability of the system.

[0090] like Figure 7 As shown, the first wind-resistant component includes a first tie rod 71. The number of first tie rods 71 ​​is generally matched with the number of rows of flexible photovoltaic brackets and the specific arrangement. The first tie rods 71 ​​are used to connect the support structures 1 of adjacent rows of flexible photovoltaic brackets in sequence, thereby forming a rigid connection between multiple rows of flexible photovoltaic brackets.

[0091] Understandably, in this embodiment, the first tie rod 71, as a major component of the first wind-resistant component, provides a direct physical connection method, enhancing additional support and stability, so that the entire photovoltaic support system can maintain structural integrity and functionality when facing severe weather conditions such as strong winds.

[0092] During installation, first ensure that the support structure of the flexible photovoltaic bracket is correctly positioned, and then fix the first tie rod 71 to the adjacent support structure 1 by bolts, clamps or other mechanical connection methods to achieve a stable connection.

[0093] Furthermore, the first wind-resistant component also includes a second tie rod 72, and each support structure has at least one first connecting end 81 and at least one second connecting end 82, wherein the horizontal position of the first connecting end 81 is higher than the horizontal position of the second connecting end 82. The first tie rod 71 and the second tie rod 72 are connected to the adjacent rows of support structures 1 in a cross manner. Specifically, the two ends of the first tie rod 71 are respectively connected to the first connecting end 81 of the previous support structure 1 and the second connecting end 82 of the next support structure 1, while the two ends of the second tie rod 72 are respectively connected to the second connecting end 82 of the previous support structure 1 and the first connecting end 81 of the next support structure 1.

[0094] A stable X-shaped structure is formed by the cross connection of the first tie rod 71 and the second tie rod 72. This structure has good mechanical stability and can effectively resist wind forces from different directions. In this embodiment, the connection between the tie rod and the support structure 1 can be achieved by bolt connection, clamp or other mechanical connection methods to ensure the firmness and reliability of the connection.

[0095] Please refer to the instruction manual attached. Figure 7 and Figure 8 The support structure 1 is designed in the form of an inverted triangular cone, which makes the support structure 1 more stable under wind force and prevents the cable structure 2 from overturning, thus playing a key role in wind resistance.

[0096] In the support structure 1 of each inverted triangular pyramid, the three endpoints at the bottom of the pyramid are defined as different first connecting ends 81, while the top endpoint serves as a second connecting end 82. Two first tie rods 71 ​​connect the two first connecting ends 81 at the bottom of one triangular pyramid to the second connecting end 82 at the top of another triangular pyramid, and a second tie rod 72 connects one first connecting end 81 at the bottom of one triangular pyramid to the second connecting end 82 at the top of another triangular pyramid. Through this connection and arrangement, the stability between the triangular pyramids is enhanced, forming a mutually supporting spatial structure.

[0097] In one embodiment, such asFigure 8 As shown, by introducing wind-resistant cables 73 as part of the first wind-resistant component, the wind resistance and structural stability of the entire system are enhanced. In each row of flexible photovoltaic supports, at least one support structure 1 is provided, and the support structures 1 on each row of supports are arranged in a one-to-one correspondence, providing a precise positioning basis for the subsequent connection of the wind-resistant cables 73.

[0098] The wind-resistant cable 73 in the first wind-resistant component is sequentially connected to the corresponding support structure 1 on each row of flexible photovoltaic brackets. Specifically, the wind-resistant cable 73 is sequentially connected to the second connection end 82 of the corresponding support structure 1 of each row of flexible photovoltaic brackets, thereby realizing the series connection of multiple rows of flexible photovoltaic brackets along the arrangement direction of multiple rows of flexible photovoltaic brackets. This not only enhances the integrity between each row of brackets, but also improves the wind resistance of the entire photovoltaic array.

[0099] It should be noted that, under normal circumstances, the extension direction of the wind-resistant cable 73 is perpendicular to the extension direction of the load-bearing cable 21 and the stabilizing cable 22, so that the entire flexible photovoltaic support system can evenly distribute the force when facing wind forces from different directions, effectively improving the system's wind resistance and overall stability.

[0100] Based on the above embodiments, the flexible photovoltaic support system further includes a plurality of second wind-resistant components 9. One end of each second wind-resistant component 9 is connected to the support structure 1 of the first row and the last row of flexible photovoltaic supports, while the other end is fixed to a preset position, so that the first row and the last row of flexible photovoltaic supports can be reinforced by the corresponding second wind-resistant components 9, ensuring the stability and reliability of the entire system.

[0101] Each second wind-resistant component 9 includes two cable assemblies 91. One side of each cable assembly 91 is connected to the corresponding support structure 1, and the other side is fixed to different preset positions. The preset positions may be pre-driven piles or ground surfaces to provide stable anchor points. That is, one end of the cable assembly 91 is connected to the corresponding support structure 1, and the other end is located at different anchor points on multiple different piles or in the ground.

[0102] The number and location of the preset positions are set according to the specific length of the first and last rows of flexible photovoltaic supports to achieve the best reinforcement effect. For example... Figure 9 As shown, the other ends of the two cable assemblies 91 are fixed to two preset positions (e.g., pile foundations), so that the second wind-resistant assembly 9 forms an inverted V-shaped structure, which helps to disperse wind force and reduce the vibration and displacement of the support.

[0103] In one embodiment, based on the above, each cable assembly 91 includes two cable members 910. When wind force acts on the flexible photovoltaic support, it is distributed to the two cable members 910, thereby reducing local stress and improving the stability of the entire system. At the same time, each support mechanism has a third connection end 83 and a fourth connection end 81, wherein the horizontal position of the third connection end 83 is higher than the horizontal position of the fourth connection end 84.

[0104] like Figure 9 As shown, one end of each of the two cable members 910 is connected to the third connection end 83 and the fourth connection end 84 of the support structure 1, respectively, and the other end is simultaneously connected to the same preset position, so that the cable assembly 91 forms a V-shaped structure in the use state. Due to the setting of the V-shaped structure, the pretension of the structure is increased, which improves the wind resistance of the system and effectively resists the action of external loads.

[0105] Furthermore, the two cable components 910 can respectively connect the load-bearing cable 21 and the stabilizing cable 22 of the flexible photovoltaic support, enhancing the overall structural stability. It is evident that in this system, the cable structure 2, the second wind-resistant component 9 (including cables and other structures), the first wind-resistant component (tie rods and other structures), and the support structure 1 are interconnected, forming a three-dimensional support network. This not only enhances the system's stability but also improves its resistance to wind, significantly extending the service life of the flexible photovoltaic support system.

[0106] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
