[0002] Solar energy is an important new energy source, and solar power generation technology has experienced rapid development in recent years. Photovoltaic supports are structures used to support solar panels in solar photovoltaic power generation systems. However, as site conditions become increasingly harsh, flexible photovoltaic supports are becoming increasingly popular to accommodate special installation environments. Flexible photovoltaic supports utilize cable structures to support solar panels, enabling large spans. They can be widely used in mountainous areas, sewage treatment plants, ponds, and other sites requiring large spans, and are gaining increasing popularity in the photovoltaic support field. Existing flexible photovoltaic supports require side tie rods to be installed at both ends of the supports to ensure structural stability. To install side tie rods between two adjacent sets of flexible photovoltaic supports, one set of photovoltaic supports is typically equipped with two side tie rods and side anchor foundations. The side tie rods are subject to significant stress, and the side anchor foundations are used to secure the side tie rods, providing both horizontal and pull-out resistance, resulting in high costs. Therefore, flexible photovoltaic support systems suffer from significant overall space waste, high project costs, and significant construction difficulties. Utility Model Content

[0030] Please refer to Figures 1 to 11As shown, the present invention discloses a photovoltaic support system 100, which includes a connecting assembly 2 and two or more groups of photovoltaic supports 1 arranged in the same row. Each group of photovoltaic supports 1 is provided with side columns 11, which are columns located at the outermost edges of each group of photovoltaic supports 1. The two adjacent groups of photovoltaic supports 1 are connected by the connecting assembly 2. One end of the connecting assembly 2 is connected to the side columns 11 of one group of photovoltaic supports 1, and the other end of the connecting assembly 2 is connected to the side columns 11 of the other group of photovoltaic supports 1. Compared with the prior art, the present invention eliminates the setting of the side tie rods described in the prior art between two adjacent groups of photovoltaic brackets 1 by setting a connecting component 2. Therefore, the photovoltaic bracket system 100 of the present invention saves installation space, saves side tie rods and pipe piles for fixing the side tie rods, which can not only effectively reduce costs and facilitate on-site construction, but also, because each group of photovoltaic brackets 1 is subjected to the same force, when connected through the connecting component 2, the connecting component 2 is subjected to tension in two directions that are offset, so the side columns 11 connected to the connecting component 2 will not deviate in any direction, thereby improving the overall stability of the system.

[0031] Please refer to Figure 2 、 Figure 4 , Figures 5 to 10 As shown, the connection assembly 2 includes a base 21, an auxiliary base 22, and an adjustable connection member 23. The adjustable connection member 23 connects the base 21 and the auxiliary base 22 as a whole, and the distance between the base 21 and the auxiliary base 22 can be linearly adjusted by the adjustable connection member 23. The adjustable connection member 23 can adjust the distance between the base 21 and the auxiliary base 22, thereby adjusting the installation length between two adjacent groups of photovoltaic brackets 1, thereby eliminating installation errors.

[0032] Please refer to Figures 5 to 10 As shown, the base 21 includes a main body 210, a first connecting end 211 and a second connecting end 212. The main body 210 extends longitudinally along a first direction, and the first connecting end 211 and the second connecting end 212 are respectively arranged at opposite ends of the main body 210 in the first direction. The first connecting end 211 is hinged to the side column 11 of one group of the photovoltaic brackets 1, and the second connecting end 212 is connected to the auxiliary seat 22, and the auxiliary seat 22 is hinged to the side column 11 of another group of the photovoltaic brackets 1. Therefore, it can be understood that when the installation length between two adjacent groups of photovoltaic brackets 1 is set to be non-adjustable, the second connecting end 212 can be directly hinged to the side column 11 of another group of the photovoltaic brackets 1; the auxiliary seat 22 is equivalent to an outwardly adjustable extension of the second connecting end 212.

[0033] Please refer to Figures 5 to 10As shown, the auxiliary seat 22 includes a first bottom plate 221, and the second connecting end portion 212 includes a second bottom plate 2121. The first bottom plate 221 and the second bottom plate 2121 are connected by the adjustable connecting member 23. The first bottom plate 221 and the second bottom plate 2121 extend parallel to each other in a second direction perpendicular to the first direction and are arranged face to face in the first direction. Figures 1 to 4 , and combined with Figure 5 and Figure 10 , if Figure 1 The vertical direction in which the side columns 11 extend is the third direction for reference. The first direction is the front-to-back direction perpendicular to the vertical direction, and the second direction is the left-to-right direction perpendicular to the vertical direction. That is, the first direction (front-to-back direction), the second direction (left-to-right direction), and the third direction (up-to-down direction) are mutually perpendicular. Because the first bottom plate 221 and the second bottom plate 2121 extend parallel to each other in the second direction and are arranged face to face in the first direction, the positioning of the adjustable connecting member 23 is facilitated, allowing the adjustable connecting member 23 to adjust the distance between the base 21 and the auxiliary base 22.

[0034] Please continue to refer to Figures 5 to 10 As shown, the adjustable connecting member 23 includes an adjusting bolt 231 and a nut 232. The first base plate 221 is provided with a first through-hole 2210, and the second base plate 2121 is provided with a second through-hole 21210. The shaft of the adjusting bolt 231 passes through the first through-hole 2210 and the second through-hole 21210, respectively. The head of the adjusting bolt 231 and the nut 232 respectively abut against opposite sides of the first base plate 221 and the second base plate 2121. As is well known in the art, the adjusting bolt 231 is a long bolt. A specific embodiment of the present invention is to adjust the relative distance between the base 21 and the auxiliary base 22 by adjusting the screw position of the nut 232 on the shaft of the adjusting bolt 231. There are two adjusting bolts 231 and two nuts 232, each of which is disposed on opposite sides of the main body 210 in the second direction in a one-to-one correspondence. This arrangement is for achieving a left-right balanced adjustment in the second direction, which is beneficial to ensuring the stability of the adjustable connecting member 23 in adjusting the distance between the base 21 and the auxiliary seat 22 .

[0035] Please refer to Figures 1 to 6 as well as Figure 11As shown, the photovoltaic support system 100 of the present invention also includes two hinge bolts 24 positioned with the side columns 11 of the photovoltaic support 1. The first connecting end 211 includes a pair of first lugs 2111, and the auxiliary base 22 includes a pair of second lugs 222. The pair of first lugs 2111 and the pair of second lugs 222 are spaced apart from each other in the second direction. Each first lug 2111 is provided with a first through-hole 21110, and each second lug 222 is provided with a second through-hole 2220. One of the hinge bolts 24 passes through the first through-hole 21110 of the first lug 2111, and the other hinge bolt 24 passes through the second through-hole 2220 of the second lug 222. With this arrangement, the present invention achieves a rotatable connection between the connecting assembly 2 and two adjacent side columns 11 (specifically, the side bases 12 above the side columns 11) of two sets of photovoltaic supports 1 through the two hinge bolts 24, further resolving the problem of inability to adapt to complex terrain.

[0036] Please refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 11 As shown, each group of photovoltaic brackets 1 further includes a side base 12 disposed above the side columns 11, and the hinge bolt 24 is positioned and connected to the side base 12. Specifically, the side base 12 is provided with a third through hole 120, which corresponds to the first through hole 21110 and the second through hole 2220, respectively, for passing the hinge bolt 24. Therefore, it can be understood that the role of the side base 12 is to facilitate positioning, thereby facilitating the rotational connection between the connecting assembly 2 and the two adjacent side columns 11 of the two groups of photovoltaic brackets 1.

[0037] Please refer to Figure 6 and Figure 11 As shown, the auxiliary seat 22 and the second connecting end portion 212 are arranged opposite to each other in the first direction, which is convenient for molding and positioning and is conducive to adjustable connection between the two.

[0038] Please refer to Figure 6 、 Figure 7 、 Figure 8 、 Figure 10 and Figure 11As shown, the second connecting end portion 212 also includes a pair of third ear plates 2122. Reinforcing ribs 20 are provided between the second ear plate 222 and the first base plate 221, and between the third ear plate 2122 and the second base plate 2121. The function of the reinforcing ribs 20 is to strengthen the structural strength of both the auxiliary seat 22 and the second connecting end portion 212. The main body 210 is a square tube. The square tube adopts a rigid structure, which has smaller deformation and better stability. The adjustment tube is preferably a rigid member with a closed cross-section structure, and can also be a C-shaped, H-shaped steel or round tube. The third ear plate 2122 is completely welded to one end and opposite sides of the square tube, which is conducive to ensuring the structural strength of the second connecting end portion 212. Compared with the third ear plate 2122 that is completely welded to one end and opposite sides of the square tube, the first ear plate 2111 is partially welded to the other end and opposite sides of the square tube. The purpose of such a setting is to expose part of the first connecting end 211 from the main body 210, so as to facilitate the formation of the first through hole 21110, that is, to facilitate the hinging at this end; in comparison, because the second connecting end 212 is not used for hinging, the third ear plate 2122 does not need to be specially set to be exposed from the main body 210.

[0039] It is also necessary to note that please refer to Figure 2 、 Figure 4 and Figure 11 The side base 12 above the side column 11 includes a first extension plate 121 extending horizontally, a second extension plate 122 extending vertically, and a third extension plate 123 fixed to the side of the second extension plate 122. Please refer to Figure 11 The third through hole 120 for the hinge bolt 24 to pass through is located on the third extension plate 123. This arrangement facilitates the rotational connection between the first connecting end 211 and the auxiliary seat 22 at the third extension plate 123 of the two adjacent side bases 12.

[0040] In this embodiment, please refer to Figures 1 to 4As shown, the photovoltaic support 1 is a flexible photovoltaic tracking support, comprising two side columns 11 at each end of the support, an intermediate column (unnumbered) located between the two side columns 11, a crossbeam 13, and a cable structure 14. Multiple crossbeams 13 are located on top of the side columns 11 and the intermediate column. The cable structure 14 passes through the crossbeams 13 and is used to support photovoltaic modules 15. The photovoltaic support 1 also includes a drive mechanism 16. In this embodiment, the drive mechanism 16 includes a motor and a rotary reducer. The motor drives the crossbeam 13 via the rotary reducer, which in turn drives the cable structure 14 and the photovoltaic modules 15 mounted on the cable structure 14 to rotate synchronously, thereby adjusting the angle of the photovoltaic modules 15 according to the changing position of the sun and achieving greater power generation. Connecting assemblies 2 are located on the side columns 11 of adjacent photovoltaic supports 1. The rotation of adjacent photovoltaic supports 1 in the same row is independent and does not affect each other. This ensures that any group of photovoltaic supports 1 can independently track the sun's altitude and meet the tracking function, while reducing project costs and construction difficulties, improving the overall stability of the system, and achieving a simple, reasonable structure and strong practicality. In other embodiments, the photovoltaic bracket 1 is a flexible photovoltaic fixed bracket, and its structure is similar to that of a flexible photovoltaic tracking bracket. The difference is that the flexible photovoltaic fixed bracket cancels the setting of the driving mechanism, and the photovoltaic components set on its cable structure are at a fixed angle and will not be adjusted accordingly with changes in the position of the sun.

[0041] It should be noted that if Figure 1 As shown, the photovoltaic support system 100 is provided with a side tie rod 17 and a pipe pile 18 on the side of the photovoltaic support 1 at the end position away from the adjacent photovoltaic support 1, that is, the photovoltaic support system 100 also includes a side tie rod 17 and a pipe pile 18, one end of the side tie rod 17 is fixed to the corresponding side column 11, and the other end is fixed to the pipe pile 18, one end of the pipe pile 18 is buried in the ground, and the other end is fixedly connected to the side tie rod 11, and the side tie rod 17 can be a flexible cable structure or a rigid rod. By arranging the side tie rod 17 and the pipe pile 18 at the end position, the stability of the photovoltaic support system 100 is further improved. That is, the photovoltaic support system 100 of the present application, wherein adjacent photovoltaic supports 1 are connected by a connecting assembly 2, and the photovoltaic support 1 at the end position of the photovoltaic support system 100 is provided with a side tie rod 17 and a pipe pile 18 on the side away from the adjacent photovoltaic support 1. By using the side tie rod 17 and the connecting assembly 2 in combination, the purpose of effectively reducing costs, facilitating on-site construction, and improving the overall stability of the system is achieved.

[0042] In summary, compared to the prior art, the present invention provides a connection assembly 2, and two adjacent groups of photovoltaic brackets 1 are connected via the connection assembly 2. One end of the connection assembly 2 is connected to the side column 11 of one group of photovoltaic brackets 1, and the other end of the connection assembly 2 is connected to the side column 11 of another group of photovoltaic brackets 1. The setting of the side tie rods described in the prior art is eliminated between the two adjacent groups of photovoltaic brackets 1. Therefore, the photovoltaic bracket system 100 of the present invention saves installation space, side tie rods and pipe piles for fixing the side tie rods, which can not only effectively reduce costs and facilitate on-site construction, but also improve the overall stability of the system. Furthermore, the two ends of the connection assembly 2 are rotatably connected to the side columns 11 of the adjacent photovoltaic brackets through hinged bolts 24, and the installation angle can be adjusted according to the terrain, thereby better adapting to complex terrain.

[0043] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on technical personnel in the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, ordinary technical personnel in the field should understand that technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
