[0043] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0044] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0046] Existing flexible support solutions include steel supports plus inclined cable anchoring solutions, or steel supports plus counterweight pier solutions. The horizontal force and support tension calculated by the above anchoring solutions are relatively large, often requiring the use of large-diameter supports and a large number of supports for inclined cables, which places high requirements on the supports.

[0047] For example, a steel support and cable anchoring scheme is adopted, in which the cable is anchored on the steel support. The cable generates a pulling force on the steel support during the stress process. At this time, the steel support is subjected to a large force, and a higher strength steel support is required, which puts higher requirements on the steel support.

[0048] The flexible bracket proposed in this application includes a support component 10, a load-bearing beam 30, and a cable member 40. The support component 10 includes at least one support member 11; the load-bearing beam 30 is horizontally arranged on at least one support member 11, and a rotating component 50 is provided on the load-bearing beam 30; the cable member 40 is passed through the rotating component 50 to be slidably connected to the rotating component 50, and one end of the cable member 40 is connected to the anchor rod 60.

[0049] It is understood that, in one embodiment, Figure 7As shown, a structural schematic diagram of a photovoltaic bracket includes two load-bearing beams 30 (of course, 3, four, or even more load-bearing beams 30 can be set according to actual needs), two support members 11, one load-bearing beam 30 is arranged on one support member 11 (of course, 2, 3, or even more support members 11 can be set under one load-bearing beam 30 according to actual needs), the two load-bearing beams 30 are arranged at intervals, and each load-bearing beam 30 is provided with two rotating components 50 (of course, 3, 4, or even more rotating components 50 can be set on one load-bearing beam 30 according to actual needs, or, it can also be understood that, in another embodiment, at least one load-bearing beam 30 is provided with a rotating component 50, and the other load-bearing beams 30 may not be provided with a rotating component 50), a cable member 40 is correspondingly provided on a rotating component 50 on a load-bearing beam 30, and a cable member 40 passes through the rotating component 50 on each load-bearing beam 30 in turn, and the two ends of the cable member 40 are connected to the anchor rod 60. When the cable member 40 is subjected to force, since the cable member 40 is passed through the rotating assembly 50 to be slidably connected to the rotating assembly 50, the cable member 40 can slide freely on the rotating assembly 50, and there is sliding friction between the cable member 40 and the rotating assembly 50, which avoids the stress between the cable member 40 and the load-bearing beam 30 being large during direct contact between the cable member 40 and the load-bearing beam 30, causing wear to the cable member 40 and the load-bearing beam 30, thereby improving the service life of the cable member 40 and the load-bearing beam 30. In addition, the cable member 40 is not directly fixed to the load-bearing beam 30. Compared with directly fixing the cable member 40 to the load-bearing beam 30 through the ear plate, the cable member 40 is The tension is completely borne by the load-bearing beam 30. In the present application, the cable member 40 does not directly generate tension on the load-bearing beam 30, thereby reducing the pulling force of the cable member 40 on the load-bearing beam 30. In addition, the cable members 40 located on both sides of the rotating assembly 50 have cable tensions F1 and F2, respectively. The horizontal component forces of the cable tensions F1 and F2 are in opposite directions, and can at least partially offset each other's horizontal component forces. The tension generated by the cable member 40 on the load-bearing beam 30 is weakened. In addition, the anchor rod 60 has a strong pull-out resistance. The use of the anchor rod 60 with a strong pull-out resistance improves the ability of the cable member 40 to load photovoltaic devices (for example, photovoltaic panels). The present application improves the service life of the cable member 40 and the load-bearing beam 30 by arranging a rotating assembly 50 on the load-bearing beam 30, and the cable member 40 is passed through the rotating assembly 50 to be slidably connected to the rotating assembly 50. One end of the cable member 40 is connected to the anchor rod 60. Through reasonable structural arrangement, the transmission of the cable tension force is improved. The cable tension force is directly transmitted from the anchor rod 60 to the foundation, thereby realizing direct and efficient force transmission, reducing the strength requirements for the load-bearing beam 30, and reducing the specifications of the load-bearing beam and the support assembly.

[0050] like Figures 1 to 6As shown, the support assembly 10 plays a supporting role and is used to support the load-bearing beam 30. The support assembly 10 includes at least one support member 11. The load-bearing beam 30 is horizontally arranged on at least one support member 11. A rotating assembly 50 is provided on the load-bearing beam 30. The cable member 40 is passed through the rotating assembly 50 to be slidably connected with the rotating assembly 50. The cable member 40 is not directly fixed on the load-bearing beam 30. One end of the cable member 40 is connected to the anchor rod 60, and one end of the cable member 40 is connected to the ground through the anchor rod 60. That is, the cable member 40 is passed through the rotating assembly 50 so that the cable member 40 can slide freely on the rotating assembly 50 to avoid During the direct contact between the cable-free member 40 and the load-bearing beam 30, the stress between the two is relatively large, causing wear on the cable-free member 40 and the load-bearing beam 30, thereby increasing the service life of the cable-free member 40 and the load-bearing beam 30. In addition, the cable-free member 40 on both sides of the rotating assembly 50 has cable tensions F1 and F2, respectively. The horizontal component forces of the cable tensions F1 and F2 are in opposite directions, and can at least partially offset each other's horizontal component forces, greatly reducing the horizontal force and root bending moment borne by the load-bearing beam 30 and the support assembly 10, reducing the requirements for the load-bearing beam 30 and the support assembly 10, and reducing the specifications of the load-bearing beam 30 and the support assembly 10.

[0051] In addition, compared with the traditional method of fixing the cables directly on the load-bearing beam, in the traditional photovoltaic bracket solution, the cables are fixed on the load-bearing beams on both sides. When the load-bearing beam and the cable on one side fail, that is, the cable becomes loose or falls off and loses its tension, the entire photovoltaic bracket cannot effectively support the photovoltaic equipment.

[0052] The present solution improves the risk resistance of the photovoltaic bracket, that is, the cable member 40 is not directly fixed on the load-bearing beam 30, but is slidably arranged on the load-bearing beam 30 through the rotating assembly 50. The pulling force of the cable member 40 on the load-bearing beam 30 is not as large as that of the above-mentioned traditional photovoltaic bracket solution. When F1 and F2 are equal in size, even if one of the two load-bearing beams 30 is non-slidingly connected to the cable member 40, because F1 and F2 are equal in size, the load-bearing beam 30 and the support assembly 10 can be prevented from being subjected to excessive horizontal force and root bending moment.

[0053] It can be understood that one end of the cable member 40 is connected to the anchor rod, which has a strong pull-out resistance. One end of the cable member 40 is connected to the ground through the anchor rod, and the tension of the cable member 40 at the end where the anchor rod is provided is directly transmitted to the foundation by the anchor rod, thereby realizing direct and efficient transmission of force.

[0054] It is understandable that if Figure 8As shown, the angles α and β between the cable members 40 on both sides of the rotating assembly 50 and the direction of gravity are equal. At this time, it can be considered that the cable members 40 on both sides of the rotating assembly 50 are symmetrically arranged. When the cable members 40 on both sides of the rotating assembly 50 are symmetrically arranged on both sides of the rotating assembly 50, the cable members 40 on both sides of the rotating assembly 50 have cable tensions F1 and F2 respectively. At this time, F1 is equal to F2. At this time, the horizontal components of the cable tensions F1 and F2 are completely offset. At this time, the horizontal force and root bending moment borne by the load-bearing beam 30 and the support assembly 10 are minimized. When the two ends of the cable member 40 are asymmetrically arranged on both sides of the rotating assembly 50, the horizontal components of the cable tensions F1 and F2 can at least be partially offset, and the horizontal force and root bending moment borne by the load-bearing beam 30 and the support assembly 10 can also be reduced.

[0055] It is understandable that if the horizontal force and root bending moment borne by the load-bearing beam 30 and the support assembly 10 are large, in order to bear the larger horizontal force and root bending moment, a stronger load-bearing beam 30 and support assembly 10 are required, such as higher-specification materials, or thicker piles, or more piles, which will increase the cost.

[0056] It is understandable that the rotating assembly can be flexibly arranged at any position of the load-bearing beam, such as the top, middle and bottom, and can be applicable to different structural forms of single-layer cables and multi-layer cables.

[0057] Therefore, the reasonable structural arrangement of the present application solution can optimize and improve the transmission of cable tension, and can give full play to the advantages of the strong compressive resistance of the support component 10 and the strong tensile resistance of the anchor rod 60. Specifically, based on the cable member 40 being passed through the rotating component 50 to be slidably connected with the rotating component 50, one end of the cable member 40 is connected to the anchor rod 60. On the one hand, the cable tension of the end of the cable member 40 where the anchor rod 60 is provided is directly transmitted to the foundation by the anchor rod 60, thereby realizing direct and efficient transmission of force. On the other hand, the cable member 40 is slidably arranged on the rotating component 50, avoiding the stress between the cable member 40 and the load-bearing beam 30 being large during the direct contact between the cable member 40 and the load-bearing beam 30, which has an impact on the cable member 40 and The load-bearing beam 30 causes wear, which increases the service life of the cable member 40 and the load-bearing beam 30. Furthermore, the cable members 40 located on both sides of the rotating assembly 50 have cable tensions F1 and F2 respectively, and their horizontal component forces can be at least partially offset, so that the load-bearing beam 30 and the support assembly 10 are subjected to reduced force. That is, the load-bearing beam 30 and the support assembly 10 are mainly used to provide a fixed fulcrum for the cable member 40 and bear the component of the cable tension in the weight direction. Therefore, smaller steel components and smaller diameter piles can be used to meet the design requirements, reduce the horizontal force and root bending moment borne by the load-bearing beam 30 and the support assembly 10, reduce the requirements for the bracket, and thus reduce costs.

[0058] In one embodiment, the support member 11 includes a support portion 111 , which includes a pile foundation 1111 and a rigid portion 1113 . The rigid portion 1113 is connected to one end of the pile foundation 1111 , and the load-bearing beam 30 is connected to one end of the rigid column 1113 away from the pile foundation 1111 .

[0059] like Figure 4 As shown, support member 11 includes support portion 111, which includes pile foundation 1111 and rigid portion 1113. Rigid portion 1113 is connected to one end of pile foundation 1111, and load-bearing beam 30 is connected to the end of rigid column 1113 facing away from pile foundation 1111. The weight-direction component of the cable tension force of cable member 40 can be sequentially transmitted from load-bearing beam 30 to rigid portion 1113, and then from rigid portion 1113 to pile foundation 1111.

[0060] That is, the support part 111 is divided into two parts. In this way, the material and structure of the pile foundation 1111 and the rigid part 1113 can be flexibly adjusted. Specifically, the pile foundation 1111 is usually used to be fixed to the ground. Different fixed areas or regions have different requirements for the pile foundation 1111. For example, some areas are highly corrosive and corrosion-resistant materials are required, or some areas have loose soil and the pile foundation 1111 needs to be immersed in water for a long time, which puts higher requirements on the support strength of the pile foundation 1111. That is, various different requirements will be put forward for the pile foundation 1111 in actual application, and the rigid part 1113 is relatively far from the ground, and the demand is not as good as the pile foundation 1111. At this time, dividing the support part 111 into two parts can effectively meet user needs while reducing costs, and avoid using the model of the pile foundation 1111 when a high-specification support part 111 is required, which increases costs. At this time, the pile foundation 1111 can adopt a high-specification model and reduce the specifications of the rigid part 1113, which is conducive to reducing costs.

[0061] In one embodiment, the support member 11 includes at least two support portions 111 , and the rigid portions 1113 of the at least two support portions 111 are connected at one end away from the pile foundation 1111 .

[0062] Considering the stability of the support and the increase in the strength of the load, the support member 11 includes at least two support parts 111, and the rigid parts 1113 of the at least two support parts 111 are connected at one end away from the pile foundation 1111. Figure 4 As shown, at least two supporting parts 111 constitute the supporting member 11, enhancing the supporting strength and stability of the supporting member 11, and the rigid parts 1113 of at least two supporting parts 111 are connected at one end away from the pile foundation 1111. At this time, the load-bearing beam 30 is arranged at one end where multiple rigid parts 1113 are connected.

[0063] In one embodiment, the anchor rod 60 is an enlarged head anchor rod.

[0064] The anchoring section of the enlarged head anchor rod is designed with an enlarged head, which can increase the contact area between the anchor rod and the foundation, thereby improving the anchoring force and stability of the anchor rod.

[0065] The anchor rod 60 in this application is an enlarged head anchor rod, which has the characteristics of strong pull-out resistance, more reliable force bearing and simpler construction than other anchor rods. In other words, the enlarged head anchor rod has the characteristics of strong pull-out resistance, especially in this application, the cable member 40 is slidably arranged on the load-bearing beam 30 through the rotating assembly 50. The cable member 40 is not directly fixed to the load-bearing beam 30, which reduces the pulling force on the load-bearing beam 30. The cable member 40 pulls a large force on the enlarged head anchor rod during the force bearing process. The use of an enlarged head anchor rod with strong pull-out resistance improves the cable member 40's ability to load photovoltaic devices (e.g., photovoltaic panels).

[0066] In one embodiment, the rotating assembly 50 includes a connecting frame 51 and a rotating member 53 . The connecting frame 51 is disposed on the load-bearing beam 30 , the rotating member 53 is disposed on the connecting frame 51 , and the cable member 40 is disposed above the rotating member 53 to be slidably connected to the rotating member 53 .

[0067] A connecting frame 51 can be set on the load-bearing beam 30, a rotating member 53 can be set on the connecting frame 51, and the cable member 40 is set above the rotating member 53, that is, the rotating member 53 is located below the cable member 40, mainly to achieve sliding friction between the cable member 40 and the rotating member 53, to avoid the stress between the cable member 40 and the load-bearing beam 30 being large during the direct contact between the two, causing wear to the cable member 40 and the load-bearing beam 30, and improving the service life of the cable member 40 and the load-bearing beam 30.

[0068] It is understandable that, in one embodiment, when a rotating assembly 50 is provided on the load-bearing beam 30 , a connecting frame 51 can be provided on the side of the load-bearing beam 30 facing the bottom surface, a rotating member 53 is provided on the connecting frame 51 , and a cable member 40 is provided above the rotating member 53 .

[0069] In one embodiment, the rotating assembly 50 includes a connecting frame 51 and two rotating members 53. The connecting frame 51 is disposed on the load-bearing beam 30. The two rotating members 53 are spaced apart from the connecting frame 51. The cable member 40 is disposed between the two rotating members 53 to be slidably connected to the two rotating members 53.

[0070] like Figure 2 and Figure 3As shown, the rotating assembly 50 includes a connecting frame 51 and two rotating members 53. The connecting frame 51 is disposed on the load beam 30. The two rotating members 53 are spaced apart from the connecting frame 51. The cable member 40 is disposed between the two rotating members 53 and is slidably connected to the two rotating members 53. As the two rotating members 53 are freely rotatable, the cable member 40 disposed between the two rotating members 53 can be slidably connected to the two rotating members 53. The two rotating members 53 ensure that the cable member 40 can slide freely without falling off. The cable members 40 on both sides of the two rotating members 53 are subjected to cable tension, which helps to offset horizontal forces. It will be understood that the connecting frame 51 can be disposed at any position on the load beam 30 as needed.

[0071] It can be understood that, compared with setting up one rotating member 53, two rotating members 53 help to improve the stability of the photovoltaic devices loaded by the entire photovoltaic bracket. For example, in one application scenario, when a typhoon occurs, the cable member 40 will move upward, and the photovoltaic devices loaded by the cable member 40 will shake. Using two rotating members 53 to clamp the cable member 40 can ensure the stability of the photovoltaic devices loaded by the cable member 40 in typhoon conditions.

[0072] In one embodiment, the connecting frame 51 includes two connecting plates, which are spaced apart and opposite to each other along the extension direction of the load-bearing beam 30; each connecting plate is provided with an upper mounting position and a lower mounting position along the up and down directions, and the two upper mounting positions of the two connecting plates are oppositely arranged to form an upper connecting position, and the two lower mounting positions of the two connecting plates are oppositely arranged to form a lower connecting position; the two rotating members 53 are respectively connected to the upper connecting position and the lower connecting position: the up and down direction is the direction of gravity.

[0073] like Figure 2 and Figure 3 As shown, in order to effectively offset the horizontal force of the cable member 40 and reduce the squeezing or pulling of the rotating member 53 in the horizontal direction, the two connecting plates are spaced apart and arranged relative to each other along the extension direction of the load-bearing beam 30. Each connecting plate is provided with an upper mounting position and a lower mounting position along the upper and lower directions. The mounting positions can be mounting holes or mounting grooves. The two upper mounting positions of the two connecting plates are arranged relative to each other to form an upper connecting position, and the two lower mounting positions of the two connecting plates are arranged relative to each other to form a lower connecting position. Figure 2 As shown, two mounting holes are formed in the upper and lower directions of each connecting plate, and the mounting holes above the two connecting plates form an upper connecting position. The two ends of the rotating member 53 located above are located at the two mounting holes. In this way, the two ends of the rotating member 53 located above are respectively connected to the two upper mounting positions, so that the upper rotating member 53 is set at the upper connecting position. Similarly, the two ends of the rotating member 53 located below are respectively connected to the two lower mounting positions, so that the lower rotating member 53 is set at the lower connecting position. The two rotating members 53 are arranged at intervals up and down, so that the cable member 40 passes through the gap between the two rotating members 53 in the horizontal direction, avoiding squeezing the rotating member 53 in the horizontal direction during the force application process of the cable member 40.

[0074] In one embodiment, the rotating member 53 includes any one of a roller, a pulley, and a bearing.

[0075] For example, in one embodiment, the rotating member 53 is a roller, in another embodiment, the rotating member 53 is a pulley, and in yet another embodiment, the rotating member 53 is a bearing.

[0076] When there are two rotating members 53, one of the two rotating members 53 comprises one of a roller, a pulley, and a bearing, while the other rotating member 53 comprises another of the roller, pulley, and bearing. For example, in one embodiment, in a scheme where the cable member 40 is located between the two rotating members 53, one rotating member 53 is a rotatable roller, while the other rotating member 53 is a bearing. The bearing includes an inner ring, an outer ring, and a ball disposed therebetween. The outer ring is rotatable relative to the inner ring. The cable member 40 is disposed between the roller and the bearing. That is, one side of the cable member 40 contacts the surface of the roller, and the other side of the cable member 40 contacts the surface of the outer ring of the bearing. The cable member 40 is sandwiched between the roller and the bearing, generating sliding friction with the roller and the bearing.

[0077] Of course, the two rotating members 53 can also have the same structure. Figure 2 As shown, the two rotating parts 53 are rollers, that is, the cable member 40 is clamped by the rollers. It can be understood that the roller pair is divided into an upper roller and a lower roller (corresponding to the upper and lower rotating parts 53). The function of the roller pair is to ensure that the cable member 40 can slide freely without falling off. After the cable member 40 is tensioned, it is fixed to the anchor rod 60 (for example, the anchor rod can be an enlarged head anchor rod). The cable tension F is directly transmitted to the foundation by the enlarged head anchor rod, thereby realizing direct and efficient force transmission, reducing the adverse effects on the rigid structure load-bearing beam 30 and the support assembly 10.

[0078] In addition, the roller pair can be replaced with a pulley pair, a bearing pair, or a combination of rollers, pulleys, and bearings. That is, the two rotating members 53 include at least one of rollers, pulleys, and bearings; or, of the two rotating members 53, one rotating member 53 includes one of rollers, pulleys, and bearings, and the other rotating member 53 includes another of rollers, pulleys, and bearings. Figure 3 As shown, the rotating part 53 is a pulley. It can be understood that replacing the roller with a pulley or a bearing can solve the problem that the contact stress between the load-bearing cable member 40 and the roller exceeds the safety limit when the tension of the load-bearing cable member 40 of the ultra-large span flexible bracket is very large. That is, using pulleys and bearings with better rotation performance can reduce the contact stress between the load-bearing cable member 40 and the pulleys and bearings.

[0079] In one embodiment, the load-bearing beam 30 includes a transverse plate, which is arranged on at least one support member 11. A through hole is opened on the transverse plate, and a slide groove 31 is provided on the structure where the periphery of the through hole is located. A ball bearing is provided in the slide groove 31. The cable member 40 is passed through the through hole and is slidably connected to the slide groove 31.

[0080] The load-bearing beam 30 includes a transverse plate. It is understood that the load-bearing beam 30 can be composed of multiple rigid structures, wherein the transverse plate is a structure provided on the support member 11 to bear the cable tension. The transverse plate is provided on at least one support member 11. A through hole is provided on the transverse plate. A chute 31 is provided on the periphery of the through hole. A ball bearing is provided in the chute 31. The cable member 40 is provided through the through hole and is slidably connected to the chute 31. Figure 5 and Figure 6 As shown, the self-rotating assembly 50 can be mounted on the web of the load-bearing beam 30, thereby resolving the problem of the cable member 40 having to pass through the web and enabling the cable member 40 to slide freely in the horizontal direction. Specifically, a through hole can be pre-set in the web of the load-bearing beam 30, and a slide groove 31 can be installed in the through hole. The slide groove 31 can be a structure with a groove formed in an annular cylinder, and a roller mounted in the groove.

[0081] In one embodiment, the through hole is oriented in a horizontal direction, wherein the horizontal direction is perpendicular to the direction of gravity; and / or the structure of the load-bearing beam 30 includes any one of a single beam, a truss, and a tensioned beam.

[0082] In order to prevent the cable member 40 from sliding through the through hole and connecting to the slide groove 31 and squeezing the slide groove 31 in the horizontal direction, a through hole is opened on the transverse plate, and the hole direction of the through hole is horizontal.

[0083] The present application does not limit the specific structure of the load-bearing beam 30. The load-bearing beam 30 includes a cross plate. It can be understood that the load-bearing beam 30 can be composed of multiple rigid structures, wherein the cross plate is a structure provided on the support member 11 to bear the cable tension. The cross plate is provided on at least one support member 11. The structure of the load-bearing beam 30 includes any one of a single beam, a truss and a tensioned beam.

[0084] The flexible bracket of the present application proposes a rigid-flexible flexible bracket side anchor solution, and its force transmission device can give full play to the advantages of the strong compressive resistance of the pile foundation and the strong tensile resistance of the enlarged head anchor rod.

[0085] In the present application, the cable member 40 is a flexible cable, which has better force transmission.

[0086] During the construction phase of the flexible support system, the prestressing of the cable members 40 can be performed directly on the ground. This not only facilitates construction but also avoids the high-altitude work required for prestressing cable tensioning in previous projects, which not only poses a safety hazard but is also time-consuming, labor-intensive, and uneconomical. Furthermore, during the later stages of the photovoltaic power station's operation, maintenance personnel can accurately detect the slack of the prestressed cables from the ground, which is very convenient and efficient, helping to reduce project operation and maintenance costs.

[0087] The present application also provides a photovoltaic support, including the flexible support as described above. For example, in one embodiment, Figure 9 As shown, a structural schematic diagram of a photovoltaic bracket includes three load-bearing beams 30 (of course, four, five, or even more load-bearing beams 30 can be set according to actual needs), two support parts 111 are set under each load-bearing beam 30 (of course, three, four, or even more support parts 111 can be set under a load-bearing beam 30 according to actual needs), the load-bearing beams 30 are arranged at intervals, and each load-bearing beam 30 is provided with two rotating components 50 (of course, three, four, or even more rotating components 50 can be set on a load-bearing beam 30 according to actual needs, or, it can also be understood that a rotating component 50 is set on at least one load-bearing beam 30, and a rotating component 50 may not be set on other load-bearing beams 30), a cable member 40 is correspondingly set on a rotating component 50 on a load-bearing beam 30, and a cable member 40 passes through the rotating component 50 on each load-bearing beam 30 in turn, and both ends of the cable member 40 are connected to the anchor rod 60.

[0088] Since the photovoltaic bracket adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0089] The above are merely exemplary embodiments of the present application and do not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the technical concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
