[0044] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0045] Reference below Figure 1-Figure 7 A photovoltaic support system 100 according to an embodiment of the present application is described. The photovoltaic support system 100 is used to install a photovoltaic component 200 to provide a mounting carrier for the photovoltaic component 200 and suspend the photovoltaic component 200 in the air, thereby improving the lighting effect at the photovoltaic component 200.

[0046] The photovoltaic support system 100 according to the embodiment of the present application includes an end support 1 , an intermediate support 2 and a cable assembly 3 .

[0047] Reference Figure 3 The mounting bracket includes two end brackets 1 arranged at intervals along a first direction, and the cable assembly 3 is connected to the two end brackets 1 at both ends of the first direction. At the same time, at least one intermediate bracket 2 is arranged between the two end brackets 1, and a through structure is arranged through the intermediate bracket 2, and the cable assembly 3 can pass through the through structure, and the cable assembly 3 is supported on the intermediate bracket 2, so as to improve the installation reliability and bearing capacity of the cable assembly 3 through the intermediate bracket 2.

[0048] The above-mentioned "continuously extending through" means that the cable assembly 3 can be arranged through the intermediate bracket 2 from the through structure, that is, the cable assembly 3 connected between the two end brackets 1 is a continuously extending cable, rather than a multi-section spliced ​​cable structure. Among them, the through structure is arranged through the intermediate bracket 2 along the first direction, and the cable assembly 3 can continuously extend along the first direction and pass through the through structure.

[0049] Among them, the cable assembly 3 is connected to two end brackets 1 located at both ends of the cable assembly 3 in the first direction, and the middle area of ​​the cable assembly 3 (i.e., the part located between the two end brackets 1) can be supported on the intermediate bracket 2 to enhance the bearing capacity of the cable assembly 3.

[0050] It should be noted that the photovoltaic assembly 200 is mounted on the cable assembly 3 to provide a mounting carrier for the photovoltaic assembly 200 through the cable assembly 3. The cable assembly 3 is a flexible structure, so that the cable assembly 3 has good structural strength to meet the assembly requirements of the photovoltaic assembly 200, and the zipper support assembly has the characteristics of flexible support, which can better resist the influence of external factors on the photovoltaic support system 100.

[0051] At present, the prestressed cable photovoltaic support system 100 can achieve high clearance and large span across the photovoltaic land area, so that it can reasonably use the land, realize land conservation and space utilization, and improve the land value. In the related art, the installation structure of the prestressed cable photovoltaic support system 100 is complicated, and anchors need to be set at the middle bracket 2 to achieve the cable turning and anchoring, resulting in a large number of components (such as cable locks, anchors, etc.) in the prestressed cable photovoltaic system 1000, which is difficult to assemble and has high costs.

[0052] In the present application, the cable assembly 3 is only fixedly connected to the mounting bracket and supported by the intermediate bracket 2 to achieve the installation of the cable assembly 3. This can reduce the number of installation components required in the photovoltaic bracket system 100 while meeting the requirements for installing and supporting the photovoltaic assembly 200, thereby reducing the difficulty of building the photovoltaic bracket system 100.

[0053] like Figure 3 As shown, in some embodiments of the present application, the cable assembly 3 is provided with a plurality of cable support units 301, and the plurality of cable support units 301 are arranged along a first direction. Among them, a cable support unit 301 is provided between the end bracket 1 and the intermediate bracket 2 arranged adjacent thereto.

[0054] It can be understood that the dividing point of the cable support unit 301 is the middle bracket 2, and the middle bracket 2 can support the cable assembly 3 to improve the bearing capacity and structural strength of each cable support unit 301. Therefore, a cable support unit 301 is arranged between the end bracket 1 and the middle bracket 2 arranged adjacent to it in the first direction.

[0055] like Figure 3 As shown, in a further embodiment of the present application, there are multiple intermediate brackets 2, and the multiple intermediate brackets 2 are arranged between the two end brackets 1, and the multiple intermediate brackets are arranged at intervals along the first direction, so as to support the cable assembly 3 respectively through the multiple intermediate brackets 2, thereby improving the installation stability and reliability of the cable assembly 3.

[0056] Among them, since the dividing point of the cable support unit 301 is the middle bracket 2, when multiple middle brackets 2 are arranged between the two end brackets 1, a cable support unit 301 is also arranged between two middle brackets 2 arranged adjacent to each other in the first direction. In other words, the multiple cable support units 301 can be arranged respectively between the end bracket 1 and the middle bracket 2 arranged adjacent to it, and between two middle brackets 2 arranged adjacent to each other in the first direction.

[0057] It can be understood that the photovoltaic support system 100 is applied to a photovoltaic field area with sufficient length in the east-west direction, and the cable assembly 3 is a support structure with flexible performance. In order to ensure the structural strength and support stability of the cable assembly 3, it is necessary to design the length of the cable support unit 301, so that a plurality of intermediate brackets 2 can be arranged between two end brackets 1 arranged opposite to each other in the first direction to provide a plurality of support structures for the cable assembly 3, and a plurality of cable support units 301 connected in sequence along the first direction can be formed at the cable assembly 3 through the plurality of intermediate brackets 2, thereby facilitating the unitized and modular design and arrangement of the photovoltaic support system 100.

[0058] In some embodiments of the present application, the cable assembly 3 includes: an installation cable 31 , a stabilizing cable 32 and a load-bearing cable 33 .

[0059] Among them, the installation cable 31 is connected between the two end brackets 1, and the installation cable 31 is used to install the photovoltaic module 200, and the installation cable 31 forms a plurality of installation segments 311 arranged in sequence along the first direction; the stabilizing cable 32 is connected between the two end brackets 1 and passes through the intermediate bracket 2, and the stabilizing cable 32 forms a plurality of stabilizing segments 321 arranged in sequence along the first direction; the load-bearing cable 33 is connected between the two end brackets 1 and passes through the intermediate bracket 2, and the load-bearing cable 33 forms a plurality of load-bearing segments 331 arranged in sequence along the first direction.

[0060] Thus, the cable assembly 3 can provide a mounting support structure for the photovoltaic assembly 200 while having good stability and load-bearing performance. A group of mounting sections 311, stabilizing sections 321 and load-bearing sections 331 constitutes a cable support unit 301.

[0061] It should be noted that the boundary of multiple cable support units 301 is at the intermediate bracket 2, and the same group of installation segments 311, stabilization segments 321 and load-bearing segments 331 refers to part of the installation cables 31, part of the stabilization cables 32 and part of the load-bearing cables 33 located between two intermediate brackets 2 arranged adjacent to each other in the first direction, and between the end bracket 1 and the intermediate bracket 2 adjacent to it.

[0062] Combination Figure 5 and Figure 6 The end of the mounting cable 31 is connected to the end bracket 1, and the mounting cable 31 passes through the intermediate bracket 2 from above the intermediate bracket 2, that is, the mounting cable 31 can be overlapped at the upper end surface of the intermediate bracket 2, so that the mounting cable 31 can be supported by the intermediate bracket 2, thereby improving the bearing and supporting effect of the mounting cable 31 on the photovoltaic module 200, and ensuring the installation stability and reliability of the photovoltaic module 200.

[0063] It is understandable that when the photovoltaic assembly 200 is installed on the installation cable 31, the gravity of the photovoltaic assembly 200 will act on the installation cable 31, and the installation cable 31 can be overlapped and supported on the intermediate bracket 2. At the same time, the tension and cable force at the installation cable 31 can be adjusted by the tensioning setting of the installation bracket.

[0064] like Figure 3 As shown, in some embodiments of the present application, the stabilizing section 321 is constructed as an arc-shaped section opened to the lower side, so as to improve the stability of the cable support unit 301 through the stabilizing section 321, thereby improving the supporting stability of the cable support unit 301 on the photovoltaic assembly 200.

[0065] like Figure 3 As shown, in some embodiments of the present application, the load-bearing section 331 is constructed as an arc-shaped section that opens upward, so as to improve the load-bearing performance of the cable support unit 301 through the load-bearing section 331, thereby improving the load-bearing capacity of the cable support unit 301 for the photovoltaic component 200.

[0066] It should be noted that the stabilizing section 321 can be constructed as an arc section opening downward while the load-bearing section 331 can be constructed as an arc section opening upward, so as to respectively improve the stability of the stabilizing cable 32 and the load-bearing performance of the load-bearing cable 33.

[0067] like Figure 3As shown, in some embodiments of the present application, the intermediate bracket 2 includes: an intermediate column 21 and a middle bracket 22, the intermediate column 21 is arranged along the vertical direction, the middle bracket 22 is arranged on the top of the intermediate column 21, and the middle bracket 22 is provided with the above-mentioned passing structure for allowing the cable assembly 3 to pass through.

[0068] It is understandable that the middle column 21 is fixed in the photovoltaic field, and the middle column 21 is the mounting carrier of the middle frame, and the middle frame can be fixed to the top of the middle column 21 to form a structure for the cable assembly 3 to pass through the top of the middle bracket 2. The middle column 21 can be constructed as a cement column, a metal column, etc., which is not specifically limited here.

[0069] like Figure 6 As shown, in a further embodiment of the present application, the passing structure includes a first passing portion 221 and a second passing portion 222 .

[0070] Among them, combined Figure 6 and Figure 7 The first through portion 221 is used for the stabilizing rope 32 to pass through, and the stabilizing rope 32 gradually increases in height from the first through portion 221 along the first direction to the side away from the first through portion 221; the second through portion 222 is provided above the first through portion 221 and is used for the load-bearing rope 33 to pass through, and the load-bearing rope 33 gradually decreases in height from the second through portion 222 along the first direction to the side away from the second through portion 222.

[0071] It should be noted that the first through portion 221 can support the stabilizing cable 32 when the stabilizing cable 32 passes through, and the support point of the middle bracket 22 for the stabilizing cable 32 is the lowest point of the two end stabilizing segments 321 in the two adjacent cable support units 301. The first through portion 221 is formed with an arc plate, which is the support point structure of the stabilizing cable 32 at the middle bracket 22. The stabilizing cable 32 can pass through the bottom of the arc plate to press and support the stabilizing cable 32 downward, so that each stabilizing segment 321 of the stabilizing cable 32 is constructed as an arc segment with an opening downward. Preferably, the opening direction of the arc plate is set upward to enhance the pressing and supporting effect of the arc plate on the stabilizing cable 32 to prevent scratches or damage to the stabilizing cable 32.

[0072] It can be further understood that the second through portion 222 is similar in structure to the first through portion 221. When the load-bearing cable 33 passes through, the second through portion 222 can support the load-bearing cable 33, and the support point position of the middle bracket 22 for the load-bearing cable 33 is the highest point of the load-bearing sections 331 at both ends of the two adjacent cable support units 301. Among them, an arc plate is also formed at the second through portion 222, and the arc plate is the support point structure of the load-bearing cable 33 at the middle bracket 22. The load-bearing cable 33 can pass through the top of the arc plate to support the load-bearing cable 33 upward, so that each load-bearing section 331 of the load-bearing cable 33 is constructed as an arc section with an opening facing upward. Preferably, the opening direction of the arc plate is set downward to enhance the pressure support effect of the arc plate on the stabilizing cable 32 to prevent scratches or damage to the load-bearing cable 33.

[0073] Among them, refer to Figure 7 The first through portion 221 and the second through portion 222 can support the stabilizing cable 32 and the load-bearing cable 33 respectively by setting an arc plate. When the tension and cable force of the cable assembly 3 are adjusted by the end bracket 1, the stabilizing cable 32 and the load-bearing cable 33 can be supported by the arc plate, thereby adjusting the direction of the stabilizing cable 32 and the load-bearing cable 33.

[0074] Specifically, a first curved plate is provided at the first passing portion 221, and an opening of the first curved plate is open upward (i.e., toward the side of the second passing portion 222), and the stabilizing cable 32 is supported on a side surface of the first curved plate away from the opening, so as to provide an arc-shaped support for the stabilizing cable 32 and guide the direction of the stabilizing cable 32; a second curved plate is provided at the second passing portion 222, and an opening of the second curved plate is open downward (i.e., toward the side of the first curved plate), and the load-bearing cable 33 is supported on a side surface of the second curved plate away from the opening, so as to provide an arc-shaped support for the load-bearing cable 33 and guide the direction of the load-bearing cable 33.

[0075] The arc-shaped plate (i.e., the first arc-shaped plate and the second arc-shaped plate) can be connected and matched with the middle bracket 22 through a connecting structure, so that the arc-shaped plate and the middle bracket 22 cooperate to define a passing structure for the stabilizing cable 32 and the load-bearing cable 33 to pass through. In other words, the middle bracket 22 forms the above-mentioned "passing structure" (i.e., the first passing portion 221 and the second passing portion 222) by arranging the arc-shaped plate, that is, the passing structure is formed by the arc-shaped plate and the outer frame of the middle bracket 22.

[0076] like Figure 3As shown, in some embodiments of the present application, there are multiple groups of cable assemblies 3, and the multiple groups of cable assemblies 3 are arranged along the second direction and connected between the two end brackets 1, and multiple groups of intermediate brackets 2 are arranged between the two end brackets 1, each group of intermediate brackets 2 includes at least one intermediate bracket 2, and each group of intermediate brackets 2 is connected and matched with a group of cable assemblies 3, so that a group of cable assemblies 3 is supported by a group of intermediate brackets 2. The first direction and the second direction are arranged vertically.

[0077] Therefore, multiple groups of cable assemblies 3 can be installed and fixed through a group of mounting brackets, so that the cable assemblies 3 are connected between the two end brackets 1, which can improve the load-bearing capacity of the photovoltaic bracket system 100.

[0078] like Figure 3 As shown, in a specific embodiment of the present application, two groups of cable assemblies 3 are connected between the two end brackets 1, and correspondingly, two groups of intermediate brackets 2 arranged along the second direction are also provided between the two end brackets 1, and each group of intermediate brackets 2 is used to be provided corresponding to a group of cable assemblies 3, so as to support a group of cable assemblies 3 through a group of intermediate brackets 2.

[0079] It should be noted that three or four groups of cable assemblies 3 may be connected between the two end brackets 1, and correspondingly, multiple groups of intermediate brackets 2 are also arranged between the two end brackets 1 to match the multiple groups of cable assemblies 3. The number of cable assemblies 3 installed on the mounting bracket and the number of intermediate brackets 2 arranged between the two end brackets 1 are not specifically limited herein.

[0080] like Figure 3 As shown, in a further embodiment of the present application, the photovoltaic support system 100 includes multiple groups of mounting brackets, which are arranged at intervals along the second direction, thereby increasing the number of mounting brackets and intermediate brackets 2 and cable assemblies 3 that match the mounting brackets, so as to further improve the carrying capacity of the photovoltaic support system 100. Each group of mounting brackets includes two end brackets 1 arranged at intervals in the first direction.

[0081] It should be noted that the number of mounting brackets provided in the photovoltaic support system 100 can be designed according to the size requirements of the photovoltaic field area, so as to increase the size of the photovoltaic support system 100 in the second direction by providing multiple groups of mounting brackets and multiple groups of intermediate brackets 2 and multiple groups of cable assemblies 3 that cooperate with the multiple groups of mounting brackets, thereby improving the carrying capacity of the photovoltaic support system 100, and a larger number of photovoltaic components 200 can be laid in the photovoltaic support system 100.

[0082] In the photovoltaic field, the first direction is preferably the east-west direction, and the second direction is preferably the north-south direction, so as to facilitate the arrangement of the photovoltaic assembly 200 in a position suitable for light exposure. Of course, the first direction and the second direction are not limited thereto and can be adjusted accordingly according to the site conditions of the photovoltaic field.

[0083] like Figure 3 As shown, in some embodiments of the present application, the photovoltaic support system 100 also includes a connecting structure 4, which is used to connect multiple groups of cable assemblies 3 arranged along the second direction, thereby improving the structural strength, stability and bearing capacity of the cable assemblies 3.

[0084] It is understandable that multiple groups of cable assemblies 3 can be connected laterally (ie connected along the second direction) through the connecting structure 4, so as to form the multiple groups of cable assemblies 3 into a stable array, so as to jointly support the photovoltaic array composed of the photovoltaic assemblies 200 through the multiple groups of cable assemblies 3.

[0085] like Figure 3 As shown, in a further embodiment of the present application, there are multiple groups of connecting structures 4, and the multiple groups of connecting structures 4 are arranged at intervals along the first direction, so as to further improve the connection stability and reliability between the multiple groups of cable assemblies 3 by setting up the multiple groups of connecting structures 4.

[0086] Reference Figure 3 In a group of cable support units 301, two groups of connecting structures 4 can be connected, and the two groups of connecting structures 4 can be arranged at the positions of the three equal division points of the cable support units 301 in the first direction, so as to improve the stability between the multiple groups of cable assemblies 3 by setting multiple groups of connecting structures 4.

[0087] Reference Figure 6 , between two groups of cable support units 301 arranged in the second direction, the connection structure 4 has a plurality of connection segments, so that the two groups of cable support units 301 are connected through the plurality of connection segments, such as: cross-connected in an "8" shape, that is, the stabilizing segment 321 in one group of cable support units 301 is connected with the load-bearing segment 331 in the other group of cable support units 301 through the connection segments. At the same time, the stabilizing segment 321 and the load-bearing segment 331 in the same group of cable support units 301 can also be connected through the connection segments.

[0088] In a further embodiment of the present application, the photovoltaic support system 100 also includes a limiter 5 and an anti-wind cable 6. The limiter 5 is arranged in the photovoltaic field, and the position of the limiter 5 is fixed relative to the intermediate support 2; the anti-wind cable 6 is connected between the connecting structure 4 and the limiter 5, so as to connect the connecting structure 4 with the limiter 5 through the anti-wind cable 6, thereby improving the wind resistance of the multiple groups of cable assemblies 3.

[0089] The limiter 5 can be a cable support unit 301, and when subjected to wind load, the limiter 5 can only have a limited displacement within the stroke allowed by the limiter 5. It is understandable that when there is wind in the environment where the photovoltaic support system 100 is located, the force of the wind can be fed back to the cable assembly 3, and the wind-resistant cable 6 cooperates with the connection structure 4 to limit the displacement of the multiple groups of cable assemblies 3 under the action of wind, so as to prevent the positions of the multiple groups of cable assemblies 3 from being greatly offset or torsional deformed, thereby improving the wind resistance performance of the photovoltaic support system 100.

[0090] Reference Figure 3 In some embodiments of the present application, the limiters 5 and the wind-resistant cables 6 are arranged on both sides of the multiple groups of cable assemblies 3 in the second direction to form a wind-resistant limit structure on the periphery of the cable assembly 3 arrangement area to improve the wind-resistant performance of the photovoltaic support system 100.

[0091] It should be noted that “the plurality of cable assemblies 3 are on both sides of the second direction” means that, in the vertical projection, the limiters 5 are arranged at the outer regions of the projections of the plurality of cable assemblies 3 in the second direction.

[0092] In some embodiments of the present application, each stopper 5 is connected to at least one wind-resistant cable 6. Figure 3 When multiple groups of connection structures 4 are connected to the same group of cable support units 301, multiple wind-resistant cables 6 are also correspondingly provided, and the multiple wind-resistant cables 6 located on the same side of the multiple groups of cable assemblies 3 in the second direction can be connected to the same limiter 5.

[0093] Reference Figure 3 In a specific embodiment, the same group of cable support units 301 are connected to two groups of connecting structures 4, each group of connecting structures 4 is connected to a wind-resistant cable 6 on both sides of the second direction, the limiter 5 is located in the middle area of ​​the two groups of connecting structures 4 in the first direction, and the two wind-resistant cables 6 located on the same side of the two groups of connecting structures 4 in the second direction are connected to the same limiter 5.

[0094] like Figure 3 As shown, in some embodiments of the present application, the end bracket 1 includes: a bracket body 11 and a cable 12, the lower end of the bracket body 11 is rotatably fixed at a first installation position 101 around a first axis, and the bracket body 11 is used to be connected to the cable assembly 3, and the first axis is arranged perpendicular to the first direction; one end of the cable 12 is fixed at a second installation position 102, and the other end of the cable 12 is connected to the upper end of the bracket body 11.

[0095] The first installation position 101 and the second installation position 102 are spaced apart in the first direction, and the first installation position 101, the second installation position 102 and the connection between the inclined cable 12 and the bracket body 11 are arranged in a triangle, thereby improving the stability of the end bracket 1.

[0096] It can be understood that since the bracket body 11 can rotate around the first axis, by tensioning the inclined cable 12 and other measures, the bracket body 11 can be driven to rotate around the first axis, thereby realizing the top displacement of the bracket body 11, so that the cable assembly 3 fixedly connected to the bracket body 11 can be synchronously displaced with the top of the bracket body 11, thereby realizing the tensioning and cable force adjustment of the cable assembly 3.

[0097] like Figure 5 As shown, in a further embodiment of the present application, the support body 11 includes a column 14 and a connecting rod 13, there are multiple columns 14, each column 14 is used to connect with a group of cable assemblies 3, and multiple columns 14 are arranged at intervals in the second direction; the connecting rod 13 is connected between the multiple columns 14 and is used to fix the multiple columns 14. Therefore, the structural strength of the support body 11 is improved by the cooperation of the connecting rod 13 and the column 14, the torsional deformation resistance of the support body 11 is improved, and the synchronous adjustment of the column 14 can be achieved by driving multiple inclined cables 12.

[0098] There are multiple stay cables 12 , and the multiple stay cables 12 are connected to the multiple columns 14 in a one-to-one correspondence.

[0099] In a specific embodiment of the present application, there are two columns 14 , each of which is connected to a stay cable 12 , and each of which is connected to two groups of stay cable assemblies 3 , and the two columns 14 are connected and fixed via a connecting rod 13 .

[0100] In some embodiments of the present application, the number of columns 14 provided on each end bracket 1 is the same as the number of groups of intermediate brackets 2, and the columns 14 and a corresponding group of intermediate brackets 2 are arranged along the first direction, so that the installation cables 31, stabilizing cables 32 and load-bearing cables 33 in the same group of cable assemblies 3 are located in the same plane, making the cable connection structure in the cable assembly 3 simple. Figure 5 and Figure 6 It should be noted that, at the intersection and overlap of the stabilizing rope 32 and the load-bearing rope 33, the stabilizing rope 32 and the load-bearing rope 33 can be arranged in a close fit in the second direction so that the stabilizing rope 32 and the load-bearing rope 33 fit closely and are arranged nearly in the same plane.

[0101] In summary, the photovoltaic support system 100 according to the embodiment of the present application has at least the following advantages:

[0102] (1) The cable assembly 3 includes an installation cable 31, a stabilizing cable 32 and a load-bearing cable 33, and the two ends of the cable assembly 3 are connected and fixed to the end brackets 1 located at the two ends of the cable assembly 3 in the first direction. The cable assembly 3 can pass through the intermediate bracket 2, and the intermediate bracket 2 can support the cable assembly 3, so as to form a plurality of cable support units 301 at the cable assembly 3, which is convenient for unitizing and modularizing the composition of the photovoltaic array while ensuring the stability of the cable assembly 3. At the same time, there is no need to anchor the cable assembly 3 on the intermediate bracket 2 or turn it at a large angle, which can reduce the number of anchors and cable joints, and reduce the construction cost of the photovoltaic bracket system 100.

[0103] (2) In the cable support unit 301, the stabilizing section 321 and the load-bearing section 331 are both arranged in an arch shape, which can improve the stability and load-bearing performance of the cable assembly 3. At the same time, the installation section 311, the load-bearing section 331 and the stabilizing section 321 in the cable support unit 301 are arranged nearly coplanar, and the function of each cable structure is clear, which is convenient for cooperating with the connection structure 4 to control the up and down displacement of the cable support unit 301 under the action of wind.

[0104] Among them, two or more cable support units 301 can be used to carry the photovoltaic assembly 200, so that the photovoltaic assembly 200 can be arranged along the optimal inclination angle, and the photovoltaic assembly 200 can also be supported to be installed in any inclination angle.

[0105] (3) At the end bracket 1, the position of the bracket body 11 can be adjusted by the inclined cable 12 to adjust the tension and cable force of the cable assembly 3, thereby improving the installation efficiency of the photovoltaic bracket system 100 and the convenience of subsequent cable force adjustment of the cable support unit 301.
