[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0022] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a photovoltaic bracket and photovoltaic system that can reduce the number of foundations and lower construction costs.

[0023] The following is for reference. Figures 1-6 A photovoltaic bracket 1 according to an embodiment of this application is described.

[0024] The photovoltaic support 1 includes a side support structure 10 and multiple spaced-apart cable-stayed mechanisms 20. The side support structure 10 includes a side column 110 and a side beam 120. The side beam 120 is installed on the side column 110. The cable-stayed mechanism 20 includes a first connecting component 210, a second connecting component 220, an anchoring base 230, and multiple spaced-apart stay cables 240. The first end of the multiple stay cables 240 is connected to the side beam 120 through the first connecting component 210, and the second end of the multiple stay cables 240 is connected to the anchoring base 230 through the second connecting component 220. The anchoring base 230 is installed on the construction site through a foundation.

[0025] In this embodiment, the side support structure 10 includes side columns 110 and side beams 120. The side columns 110 are installed in the construction site, which includes, but is not limited to, areas with high difficulty in foundation construction such as tidal flats, water areas, and salt fields.

[0026] Side beam 120 is installed on the top of side column 110. Side beam 120 extends along the width direction of photovoltaic bracket 1 and is used to connect the cable 30 structure of photovoltaic flexible bracket to support photovoltaic modules.

[0027] The cable-stayed structure 20 includes a first connecting component 210, a second connecting component 220, an anchoring base 230, and multiple stay cables 240. The anchoring base 230 is installed at the construction site. The multiple stay cables 240 are spaced apart along the width direction of the photovoltaic support 1, and each stay cable 240 has the same included angle with the side column 110. The first connecting component 210 is used to connect the first end of the stay cable 240 to the side beam 120, and the second connecting component 220 is used to connect the second end of the stay cable 240 to the anchoring base 230. The stay cables 240 include, but are not limited to, steel strands, steel tie rods, and threaded steel.

[0028] The side beam 120 has a first ear plate 122 on the side facing the inclined tension mechanism 20. The first ear plate 122 is integrally formed with the side beam 120 or fixedly connected by welding. The first connecting assembly 210 is hinged to the side beam 120 through the first ear plate 122. The first connecting assembly 210 may include a first shaft 211, which is through-fitted with the first ear plate 122 to form a rotating hinge structure. The top of the anchoring base 230 has a second ear plate 232, which is integrally formed with the anchoring base 230 or fixedly connected by welding. The second connecting assembly 220 is hinged to the anchoring base 230 through the second ear plate 232. The second connecting assembly 220 may include a second shaft 221, which is through-fitted with the second ear plate 232 to form a rotating hinge structure. In addition, the end hinge portion includes, but is not limited to, a rotating shaft, a ball joint, a spherical gasket, a universal joint, etc.

[0029] The first ends of multiple stay cables 240 are parallel and pass through the first shaft 211, which can realize the adaptive deflection of the stay cables 240. Under the action of wind load, temperature deformation or slight foundation settlement, the stay cables 240 can rotate relative to the first shaft 211 to adapt to the angle change, thereby solving the problem of bending stress concentration caused by rigid connection.

[0030] The second connecting assembly 220 also includes an adjusting assembly 222, which is connected between the second end of the stay cable 240 and the second shaft 221, and is used to adjust the length and tension of the stay cable 240. The adjusting assembly 222 allows for adjustments to meet actual connection requirements even when there are deviations in the anchor pile driving position. The adjusting assembly 222 includes, but is not limited to, single-end bolt adjustment, double-end bolt adjustment, or intermediate section bolt adjustment.

[0031] The first connecting assembly 210 further includes a first anchor 212 and a first seal 213, and the second connecting assembly 220 further includes a second anchor 227 and a second seal 228. The first anchor 212 and the second anchor 227 include, but are not limited to, blind hole compression anchors. The ends of the steel strands of the stay cable 240 extend into the blind hole of the blind hole compression anchor, and anchoring is achieved using a mechanical compression process. The compression anchor can deform radially under external force, fixing the steel strands to it as a single unit. The first sealing element 213 and the second sealing element 228 include, but are not limited to, multiple sealing structures such as plastic sealing rolls. Multiple sealing structures are provided at the port of the blind hole extrusion anchor. The multiple sealing structures include, from the inside to the outside, a rubber sealing gasket, a weather-resistant and corrosion-resistant sealing sleeve, and a waterproof and corrosion-resistant sealing layer. The rubber sealing gasket is located inside the port of the blind hole extrusion anchor and fits tightly with the outer wall of the steel strand. The weather-resistant and corrosion-resistant sealing sleeve is fitted outside the port of the blind hole extrusion anchor. The waterproof and corrosion-resistant sealing layer fills the gaps between the sealing layers, thus constructing a multiple sealing protection system to prevent external salt spray, seawater, water vapor, etc. from entering the interior of the anchor.

[0032] The number of stay cables 240 in the cable-stayed mechanism 20 is not limited to two and can be set according to actual load requirements. The number of first anchors 212, first seals 213, second anchors 227, and second seals 228 are the same as the number of stay cables 240, and each corresponds one-to-one with a stay cable 240. In other words, the first end of the stay cable 240 is connected to the first anchor 212, and the connection between the first anchor 212 and the stay cable 240 is provided with a first seal 213; the second end of the stay cable 240 is connected to the second anchor 227, and the connection between the second anchor 227 and the stay cable 240 is provided with a second seal 228.

[0033] Flexible photovoltaic (PV) supports bear PV modules by tensioning prestressed steel strands between two supporting structures. As PV power plant construction expands to special sites such as tidal flats, shallow seas, saline-alkali lands, and aquaculture areas, the high humidity, high salt spray, strong corrosion, complex wind loads, and weak foundation conditions of these environments lead to increasingly higher performance requirements for the end anchoring structures of flexible PV supports, indicating room for improvement.

[0034] In related technologies, the edge support structure of a photovoltaic flexible support system typically includes edge columns and edge beams mounted on the edge columns. The edge beams connect the main cables and other cable structures to support the photovoltaic modules. To ensure the overall stability of the flexible support, a cable-stayed mechanism is required at the edge. This mechanism typically includes stay cables and anchor foundations. One end of the stay cable connects to the edge beam, and the other end connects to the anchor foundation. However, traditional structures often use an independent anchor point configuration with one cable and one pile. Each stay cable has its own independent foundation and anchor seat. In areas such as water bodies and tidal flats, foundation construction is difficult and time-consuming, significantly increasing the overall project cost. Furthermore, due to the influence of site topography, construction deviations, and foundation settlement, the inclination angles of each stay cable are difficult to maintain consistently, resulting in uneven load distribution and reduced overall support structure stability.

[0035] The cable-stayed structure 20 of this application is installed on the construction site via a foundation. Each cable-stayed structure 20 corresponds one-to-one with a foundation. The cable-stayed structure 20 includes multiple cable stays 240 spaced apart along the width of the photovoltaic support 1. Each cable stay 240 within the cable-stayed structure 20 is connected to the side beam 120 via a first connecting component 210 and to the anchorage base 230 via a second connecting component 220, achieving a single anchor point layout for multiple cable stays 240s. The shared node design of the multiple cable stays 240s within the cable-stayed structure 20 significantly reduces the number of foundations compared to the traditional one-cable-one-pile structure, significantly reducing foundation construction, material, and labor costs, and helping to reduce the occupation and damage of foundations to aquaculture and salt production areas. Simultaneously, the inclination angle of the multiple cable stays 240s within the cable-stayed structure 20 remains consistent due to the shared anchorage base 230, which can reduce the risk of uneven cable force caused by anchor point dispersion, construction deviations, and foundation settlement, thus helping to improve the wind resistance and operational stability of the entire photovoltaic support 1. Through the through-connection of the adaptive rotating shaft and the hinged lug, a rotating hinge structure is formed, allowing the stay cable 240 to rotate freely in multiple directions. This adapts to angle changes caused by construction errors, terrain slope, and foundation settlement, eliminating stress concentration due to bending. By adjusting the component 222 on-site to correct installation deviations and precisely applying prestress, the installation tolerance can be improved, reducing the precision requirements for construction in complex sites. The combination of blind hole extrusion anchors and multiple sealing structures effectively blocks salt spray and moisture corrosion, making it suitable for highly corrosive environments such as solar-salt complementary and fishery-solar complementary photovoltaic power stations. Furthermore, the stay mechanism 20 can be assembled in the factory and transported as a whole to the construction site for installation, helping to reduce on-site assembly steps and improve construction and installation efficiency.

[0036] According to the photovoltaic support 1 provided in this application, the common node design of multiple stay cables 240 in the cable-stayed mechanism 20 sharing the same anchor base 230 can reduce the number of foundations, reduce construction costs, and improve construction and installation efficiency.

[0037] In some embodiments, at least one of the first connecting component 210 and the second connecting component 220 includes an adjusting component 222 for adjusting the length of the stay cable 240.

[0038] In this embodiment, the adjustment component 222 can be at least one of the following structural forms: Example 1: The first connection component 210 includes an adjustment component 222.

[0039] In this embodiment, the adjustment component 222 is connected to the first end of the stay cable 240 and is used to adjust the actual length of the stay cable 240.

[0040] Example 2: The second connection component 220 includes an adjustment component 222.

[0041] In this embodiment, the adjustment component 222 is connected to the second end of the stay cable 240 and is used to adjust the actual length of the stay cable 240.

[0042] Example 3: The first connecting component 210 includes a first adjusting component, and the second connecting component 220 includes a second adjusting component.

[0043] In this embodiment, the first adjustment component is connected to the first end of the stay cable 240, and the second adjustment component is used to adjust the second end connection of the stay cable 240. The first adjustment component and the second adjustment component can adjust the actual length of the stay cable 240 independently, or they can adjust the actual length of the stay cable 240 simultaneously.

[0044] The following description uses the second connecting component 220, which includes the adjusting component 222, as an example.

[0045] In some embodiments, such as Figure 3 and Figure 5 As shown, the second connecting assembly 220 includes a second shaft 221 and an adjusting assembly 222. The second shaft 221 is connected to the anchor base 230, and the adjusting assembly 222 is connected between the second shaft 221 and the second end of the stay cable 240.

[0046] In this embodiment, the second connecting component 220 is used to connect the second end of the stay cable 240 to the anchor base 230. The second connecting component 220 includes a second shaft 221 and an adjusting component 222.

[0047] The second shaft 221 can be a cylindrical shaft, the diameter of which is adapted to the shaft hole of the second ear plate 232 on the anchoring base 230. The second shaft 221 is disposed through the shaft hole of the second ear plate 232, forming a rotating hinge structure with the second ear plate 232. The second shaft 221 can rotate in the shaft hole of the second ear plate 232, thereby realizing the adaptive angle deflection of the stay cable 240.

[0048] The adjustment component 222 is connected between the second shaft 221 and the second end of the stay cable 240, and is used to adjust the length and tension of the stay cable 240.

[0049] In some embodiments, such as Figure 3 and Figure 5 As shown, the adjustment assembly 222 includes a first adjustment member 223 and a second adjustment member 224. The first adjustment member 223 is provided with a first connecting hole 225 and a second connecting hole 226. The second adjustment member 224 is installed on the first adjustment member 223 through the first connecting hole 225 and is connected to the second shaft 221. The second end of the cable 240 is connected to the first adjustment member 223 through the second connecting hole 226.

[0050] In this embodiment, the adjustment assembly 222 is connected between the second shaft 221 and the second end of the stay cable 240, and the adjustment assembly 222 includes a first adjustment member 223 and a second adjustment member 224.

[0051] The first adjusting member 223 can be an adjusting pad, and the whole is in the form of a plate or sheet. The first adjusting member 223 is provided with a first connecting hole 225 and a second connecting hole 226.

[0052] Both the first connecting hole 225 and the second connecting hole 226 are through holes, penetrating the surface of the first adjusting member 223. The first connecting hole 225 and the second connecting hole 226 are spaced apart along the length of the first adjusting member 223. The first connecting hole 225 is used to install the second adjusting member 224, and the second connecting hole 226 is used to connect the second end of the stay cable 240.

[0053] The second adjusting member 224 may include an adjusting bolt and an adjusting nut. The adjusting bolt includes, but is not limited to, a U-bolt. One open end of the adjusting bolt passes through the first connecting hole 225 of the first adjusting member 223, and the other end is connected to the second shaft 221.

[0054] After one end of the second adjusting member 224 passes through the first connecting hole 225, it is fixedly connected to the first adjusting member 223 by adjusting nut. The adjusting nut can limit the axial position of the second adjusting member 224 relative to the first adjusting member 223. At the same time, by cooperating with the adjusting bolt and adjusting nut, the distance between the first adjusting member 223 and the second shaft 221 can be changed, thereby adjusting the length of the inclined pull mechanism 20.

[0055] During on-site installation, the adjusting nut can be turned to drive the adjusting pad to move along the length of the adjusting bolt, thereby moving the stay cable 240 and adjusting the overall length of the stay mechanism 20 and controlling the cable force.

[0056] In some embodiments, such as Figure 2 As shown, the angles between the multiple stay cables 240 and the side columns 110 within the same cable-stayed mechanism 20 are the same.

[0057] In this embodiment, the cable-stayed mechanism 20 includes a first connecting component 210, a second connecting component 220, an anchoring base 230, and a plurality of cable stays 240. The anchoring base 230 is installed in the construction site, and the plurality of cable stays 240 are spaced apart along the width direction of the photovoltaic support 1. The first connecting component 210 is used to connect the first end of the cable stay 240 to the side beam 120, and the second connecting component 220 is used to connect the second end of the cable stay 240 to the anchoring base 230.

[0058] The angles between the multiple stay cables 240 within the same cable-stayed mechanism 20 and the side column 110 are the same, meaning that the angles of inclination of the multiple stay cables 240 relative to the horizontal plane are consistent. The extension directions of the multiple stay cables 240 within the same cable-stayed mechanism 20 can be parallel or intersecting.

[0059] The angles between the multiple stay cables 240 and the side column 110 within the same cable-stayed mechanism 20 are the same, which makes the force direction of the multiple stay cables 240 consistent. Under the action of wind load, temperature load, etc., the multiple stay cables 240 can work together to bear the force.

[0060] In actual operation, the load transmitted by the side beam 120 is jointly borne by multiple stay cables 240, eliminating the problem of uneven load distribution due to angle differences. Furthermore, the multiple stay cables 240 share the same anchorage base 230, the same first shaft 211, and the same second shaft 221, simplifying the construction of connection nodes, reducing the number of components, and thus lowering manufacturing and installation costs.

[0061] In some embodiments, such as Figure 3 As shown, the first connecting assembly 210 includes a first shaft 211 and a first anchor 212. The first shaft 211 is hinged to the side beam 120, and the first anchor 212 is installed on the first shaft 211 and connected to the first end of the stay cable 240.

[0062] In this embodiment, the cable-stayed mechanism 20 includes a first connecting component 210, a second connecting component 220, an anchoring base 230, and multiple cable stays 240. The first connecting component 210 is used to connect the first end of the cable stay 240 to the side beam 120. The first connecting component 210 includes a first shaft 211, a first anchor 212, and a first seal 213.

[0063] The first shaft 211 can be a semi-cylindrical or cylindrical shaft, the diameter of which is adapted to the shaft hole of the first ear plate 122 on the side beam 120. The first shaft 211 is disposed through the shaft hole of the first ear plate 122, forming a rotating hinge structure with the first ear plate 122, and the hinge axis extends along the width direction of the photovoltaic bracket 1. The first shaft 211 can rotate in the shaft hole of the first ear plate 122 to realize the adaptive angle deflection of the stay cable 240.

[0064] The first shaft 211 has a channel for the stay cable 240 to pass through. The channel extends radially along the first shaft 211. After the first end of the stay cable 240 passes through the channel, it is connected to the first anchor 212, which abuts against the first shaft 211.

[0065] The first seal 213 is installed on the first anchor 212 to seal the connection between the first anchor 212 and the stay cable 240. The first seal 213 is a multi-seal structure, including at least a rubber sealing gasket, a weather-resistant and corrosion-resistant sealing sleeve, and a waterproof and corrosion-resistant sealing layer arranged sequentially from the inside to the outside.

[0066] A rubber sealing gasket is placed inside the port of the first anchor 212 and sleeved on the outside of the steel strand of the stay cable 240. It fits tightly against the outer wall of the steel strand to form the first sealing barrier, preventing moisture and salt spray from seeping into the anchor along the surface of the steel strand.

[0067] The weather-resistant and corrosion-resistant sealing sleeve is fitted over the port of the first anchor 212, completely covering the port of the first anchor 212 and the rubber sealing gasket, forming a second sealing barrier. The weather-resistant and corrosion-resistant sealing sleeve is made of weather-resistant rubber or polymer anti-corrosion materials, and has good aging resistance and salt spray resistance.

[0068] A waterproof and corrosion-resistant sealing layer fills the gaps between the rubber sealing gasket and the weather-resistant and corrosion-resistant sealing sleeve, as well as the tiny gaps between the first anchor 212 and the stay cable 240, forming a third sealing barrier. The waterproof and corrosion-resistant sealing layer can be made of waterproof and corrosion-resistant sealant or epoxy resin materials, which, after curing, form a dense sealing layer to prevent the intrusion of external corrosive media.

[0069] The triple sealing structure works together to form a complete sealing and protection system, which can effectively prevent salt spray, seawater and water vapor from entering the interior of the first anchor 212, and help the anchoring node to operate reliably for a long time in highly corrosive environments such as salt-photonic complementary and fishing-photonic complementary environments.

[0070] In some embodiments, the first anchor 212 has a blind hole, at least a portion of the stay cable 240 is located within the blind hole and is interference-fitted with the blind hole.

[0071] In this embodiment, the first connecting component 210 is used to connect the first end of the stay cable 240 to the side beam 120. The first connecting component 210 includes a first shaft 211, a first anchor 212 and a first seal 213.

[0072] The first shaft 211 is a cylindrical shaft that passes through the shaft hole of the first ear plate 122 on the side beam 120, forming a rotating hinge structure with the first ear plate 122.

[0073] The first anchor 212 can be a blind hole compression anchor. The first anchor 212 is cylindrical in shape, with a blind hole at one end. The blind hole is a non-through hole extending inward from the end face of the first anchor 212, and its bottom is closed. The first end of the stay cable 240 extends into the blind hole of the first anchor 212. Through a mechanical compression process, the first anchor 212 is radially deformed, firmly anchoring the stay cable 240 into the blind hole. The blind hole compression anchor eliminates the risk of loosening or slippage of the clamps and exhibits excellent fatigue resistance.

[0074] Furthermore, compared to through-hole anchors, blind holes have a closed bottom, and the blind hole structure means that the first anchor 212 only needs to be sealed on the open end side, simplifying the design of the sealing structure.

[0075] The first sealing element 213 is installed at the blind hole opening end of the first anchor 212 to seal the gap between the blind hole opening end and the stay cable 240. The first sealing element 213 may adopt a multi-seal structure, including a rubber sealing gasket, a weather-resistant and corrosion-resistant sealing sleeve, and a waterproof and corrosion-resistant sealing layer arranged sequentially from the inside to the outside.

[0076] In some embodiments, the second anchor 227 has a blind hole, at least a portion of the stay cable 240 is located within the blind hole and is interference-fitted with the blind hole.

[0077] In some embodiments, such as Figure 4 As shown, the side beam 120 includes a beam body 121 and multiple sets of first ear plates 122 spaced apart along the width direction of the photovoltaic support 1, and a first shaft 211 is connected between two first ear plates 122 in the same set.

[0078] In this embodiment, the beam body 121 is a load-bearing component extending along the width direction of the photovoltaic bracket 1, and multiple sets of first ear plates 122 are spaced apart along the width direction of the photovoltaic bracket 1, with each set of first ear plates 122 correspondingly connected to a first shaft 211.

[0079] Each set of first ear plates 122 includes two oppositely arranged first ear plates 122, with an installation space between the two first ear plates 122. The first ear plates 122 can be integrally formed or welded to the beam body 121 for fixed connection. The first ear plates 122 are provided with shaft holes, and the shaft holes of the two first ear plates 122 in the same set are coaxially arranged for mounting the first shaft 211.

[0080] The two ends of the first shaft 211 are respectively inserted into the shaft holes of the two first ear plates 122 in the same group. The first shaft 211 can rotate freely relative to the shaft holes of the first ear plates 122, thus forming a rotating hinge structure.

[0081] The length of the first shaft 211 is greater than the distance between the two first ear plates 122 in the same group, and its two ends extend outward from the outer sides of the two first ear plates 122 respectively.

[0082] After installation, the first anchor 212 and the first seal 213 are located in the installation space between the two first ear plates 122 in the same group.

[0083] In some embodiments, such as Figure 4 As shown, the photovoltaic support 1 also includes a cable 30, and a plurality of cable anchors 123 are provided on the side beam 120. The cable anchors 123 and the first ear plate 122 are distributed at intervals along the width direction of the photovoltaic support 1. The cable anchors 123 are used to install the cable 30.

[0084] In this embodiment, multiple sets of first ear plates 122 are spaced apart along the width direction of the photovoltaic bracket 1. Each set of first ear plates 122 includes two first ear plates 122 arranged opposite to each other, and a first shaft 211 is connected between the two first ear plates 122 in the same set.

[0085] Cable anchors 123 are installed on the beam body 121 of the side beam 120 for installing cables 30. Cables 30 include load-bearing cables and module cables of the photovoltaic flexible support. The load-bearing cables are used to bear the gravity load of the photovoltaic modules, and the module cables are used to fix the photovoltaic modules. The ends of cables 30 are anchored to the side beam 120 by cable anchors 123.

[0086] The cable anchor 123 can take many forms, including but not limited to extrusion anchors, wedge anchors, or cast anchors.

[0087] The cable anchors 123 and the first ear plate 122 are spaced apart along the width of the photovoltaic support 1 and are also spaced apart circumferentially on the side beam 120. This alternating distribution ensures that the anchor points of the cable 30 and the connection points of the inclined cable 240 are evenly spaced on the side beam 120, resulting in reasonable stress distribution.

[0088] In some embodiments, such as Figure 5 As shown, the second connecting assembly 220 also includes a second anchor 227 and a second seal 228. The second anchor 227 is connected to the second end of the stay cable 240, and the second seal 228 is installed on the second anchor 227 to seal the connection between the second anchor 227 and the stay cable 240.

[0089] In this embodiment, the first adjusting member 223 has a second connecting hole 226 for the stay cable 240 to pass through. The second end of the stay cable 240 passes through the second connecting hole 226 and is connected to the second anchor 227. The second anchor 227 abuts against the first adjusting member 223.

[0090] The second anchor 227 can be a blind-hole compression anchor, which is cylindrical in shape and has a blind hole at one end. The blind hole is a non-through hole extending inward from the end face of the second anchor 227, with a closed bottom. The second end of the stay cable 240 extends into the blind hole of the second anchor 227, and the second anchor 227 is radially deformed through a mechanical compression process, firmly anchoring the stay cable 240 in the blind hole. The blind-hole compression anchor has no risk of wedge loosening or slippage and has excellent fatigue resistance.

[0091] The second seal 228 is installed on the second anchor 227 to seal the connection between the second anchor 227 and the stay cable 240. The second seal 228 has a multi-seal structure, including at least a rubber sealing gasket, a weather-resistant and corrosion-resistant sealing sleeve, and a waterproof and corrosion-resistant sealing layer arranged sequentially from the inside to the outside.

[0092] After installation, the second anchor 227 is located on the side of the first adjusting member 223 facing the second shaft 221 and is connected to the second end of the stay cable 240. The second anchor 227 is used to reliably anchor the second end of the stay cable 240 to the first adjusting member 223.

[0093] In some embodiments, such as Figure 6 As shown, the anchoring base 230 includes a base plate 231 and a plurality of second ear plates 232 spaced apart along the width direction of the photovoltaic bracket 1, and the second shaft 221 is hinged to the second ear plates 232.

[0094] In this embodiment, the anchor base 230 is installed in the construction site via a foundation, such as a foundation fixed in the ground, with the anchor base 230 fixedly installed on top of the foundation. The connection between the anchor base 230 and the foundation can be either integral casting or bolted connection.

[0095] The anchoring base 230 includes a base plate 231 and a plurality of second ear plates 232 spaced apart along the width direction of the photovoltaic support 1. The base plate 231 is fixedly disposed on the top of the foundation, and the second ear plates 232 are fixedly disposed on the upper surface of the base plate 231. The plurality of second ear plates 232 are spaced apart along the width direction of the photovoltaic support 1. The second ear plates 232 and the base plate 231 can be integrally formed or welded together for fixed connection.

[0096] The second ear plate 232 has a shaft hole, and the shaft holes of two adjacent second ear plates 232 are coaxially arranged for mounting the second shaft 221. The two ends of the second shaft 221 are respectively inserted between two adjacent second ear plates 232, and the second shaft 221 can rotate relative to the shaft hole of the second ear plate 232, thus forming a rotating hinge structure.

[0097] The anchoring base 230 also includes reinforcing ribs, which are disposed between the base plate 231 and the second ear plate 232. The reinforcing ribs can be triangular or trapezoidal plates, with one side connected to the upper surface of the base plate 231 and the other side connected to the side of the second ear plate 232. The reinforcing ribs effectively improve the bending stiffness and load-bearing capacity of the second ear plate 232.

[0098] This application also provides a photovoltaic system.

[0099] The photovoltaic system includes a photovoltaic support 1 and photovoltaic modules, with the photovoltaic modules mounted on cables 30 of the photovoltaic support 1.

[0100] Photovoltaic systems can be applied to photovoltaic power stations such as those for fisheries and solar power in tidal flats and those for salt and solar power in saline-alkali land, which helps reduce the occupation and damage of foundations to aquaculture and salt production areas. At the same time, it can reduce the risk of uneven cable tension caused by scattered anchor points, construction deviations, and foundation settlement, which helps to improve the wind resistance and operational stability of the entire photovoltaic support frame 1.

[0101] According to the photovoltaic system provided in this application, the photovoltaic bracket 1 mentioned above can effectively block salt spray and moisture erosion, and is suitable for highly corrosive environments such as salt-photovoltaic complementary and fishery-photovoltaic complementary power stations.
