Description

Technical Field

[0001] The present application belongs to the field of photovoltaic building technology, and specifically relates to a photovoltaic shading system. Background Art

[0002] In modern buildings, most solar photovoltaic cells are placed on the roof or building facades. The photovoltaic system is attached to the building, and the building serves as a carrier to support it. The photovoltaic system mainly completes the task of power generation. The photovoltaic system on the facade of the building curtain wall uses the space provided by the building facade to install solar photovoltaic panels.

[0003] Among them, using photovoltaic cell modules as external shading components for windows is a typical method in current photovoltaic building integration systems. It can not only ensure reasonable lighting and reduce solar radiation through windows, but also convert solar energy into electrical energy to alleviate the pressure on the power grid.

[0004] However, conventional photovoltaic building shading solutions involve mounting a PV bracket on one end connected to the building and suspended in the air on the other. The PV modules are mounted on the bracket. While this structure can achieve photovoltaic shading, the size and number of the brackets must be strictly matched to the modules, resulting in limited flexibility. Furthermore, this structure only provides horizontal shading, making it impractical for scenarios requiring vertical shading. Utility Model Content

[0047] The following will be combined with the 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 part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0048] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0049] The photovoltaic shading system and electronic equipment provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0050] like Figure 1As shown, an embodiment of the present application provides a photovoltaic shading system, comprising: a first supporting frame 1 and a second supporting frame 2 for connecting to a building, the first supporting frame 1 and the second supporting frame 2 being arranged opposite to each other; a photovoltaic unit 3 is installed between the first supporting frame 1 and the second supporting frame 2 along a first direction, the first direction being a direction extending from the surface of the first supporting frame 1 to the surface of the second supporting frame 2; the photovoltaic unit 3 comprises: a flexible cable 31, at least one photovoltaic component 32, and a connecting structure 33 for fixing the photovoltaic component 32 to the flexible cable 31.

[0051] In the embodiment of the present application, the first support frame 1 and the second support frame 2 are configured to connect the photovoltaic unit 3 to the building, thereby achieving a sunshade effect for the photovoltaic unit 3. The first support frame 1 and the second support frame 2 are arranged opposite each other, with a certain distance between them along a first direction. The photovoltaic unit 3 is arranged between the first support frame 1 and the second support frame 2 along the first direction and is connected to both the first support frame 1 and the second support frame 2. The first direction is the direction extending from the surface of the first support frame 1 to the surface of the second support frame 2. Optionally, the surface of the first support frame 1 and the surface of the second support frame 2 can refer to the opposing surfaces of the two support frames. For example, if the first support frame 1 and the second support frame 2 are arranged above each other, the surface of the first support frame 1 and the surface of the second support frame 2 can refer to the lower surface of the first support frame 1 and the upper surface of the second support frame 2. The photovoltaic unit 3 is configured to provide sunshade on the building surface and also provide a photovoltaic function. Specifically, the photovoltaic unit 3 includes a photovoltaic assembly 32, a flexible cable 31, and a connecting structure 33. The photovoltaic assembly 32 is configured to provide both sunshade and photovoltaic functions, and the connecting structure 33 is configured to securely connect the photovoltaic assembly 32 to the flexible cable 31.

[0052] Furthermore, in order to better utilize the surface size of the building, when setting up the photovoltaic shading system, the modules between the photovoltaic assembly 32 and the surface size of the building are matched as much as possible. Compared with the prior art that uses a bracket as the supporting connection structure 33 of the photovoltaic assembly 32, the setting of the flexible cable 31 is more flexible. The size of the flexible cable 31 along the first direction can be set according to the surface size of the building, and is no longer limited by the size setting of the connection point between the bracket and the building, which wastes the size of the building surface. When the surface size of the building is the same, the setting of the flexible cable 31 has the beneficial effect of improving the overall economy of the photovoltaic shading system. In addition, the flexible cable 31 has the advantage of being lighter than the bracket, which reduces the burden of the photovoltaic shading system on the building and has the beneficial effect of reducing the adverse effects of the photovoltaic shading system on the building surface. Furthermore, the flexible cable 31 has a certain deformation amount. In the photovoltaic shading system, when a high wind load occurs in the outside world, the flexible cable 31 has a certain resistance compared to the bracket.

[0053] It should be noted that the photovoltaic shading system can be installed on the facade of a building or on the roof of a building. Specifically, when the photovoltaic shading system is installed on the facade of a building, the first direction is along the facade.

[0054] Further optionally, the first supporting frame 1 and the second supporting frame 2 can be connected to the protruding parts of the building surface respectively, or can be directly connected to the building surface through other connecting parts. This embodiment does not impose any limitation on this.

[0055] Optionally, in the embodiment of the present application, Figure 1 and Figure 2 As shown, there are multiple photovoltaic assemblies 32 , which are arranged in sequence along the first direction; and / or there are multiple photovoltaic units 3 , which are arranged at intervals along the extension direction of the first supporting frame 1 .

[0056] In the embodiment of the present application, the length of the flexible cable 31 can be set according to the size and module of the photovoltaic module 32. In order to better utilize the photovoltaic unit 3 to achieve sunshade and photovoltaic effects, increase the sunshade area and increase the coverage area of ​​the photovoltaic module 32, the photovoltaic unit 3 may include multiple photovoltaic modules 32, and the multiple photovoltaic modules 32 are arranged in sequence along the first direction and connected to the flexible cable 31 through the connecting structure 33. Figure 12 As shown, multiple photovoltaic units 3 are connected to the first supporting frame 1 and the second supporting frame 2, and multiple photovoltaic units 3 are arranged at intervals along the extension direction of the first supporting frame 1 to achieve coverage on the surface of the building. On the one hand, shading of the building surface is achieved, and on the other hand, the setting of multiple photovoltaic units 3 also has the beneficial effect of increasing the power generation of the photovoltaic shading system.

[0057] Optionally, in the embodiment of the present application, Figure 2 As shown, the photovoltaic component 32 includes two first edges 321 arranged opposite to each other, and two second edges 322 arranged opposite to each other. The first edge 321 and the second edge 322 intersect, and the length of the first edge 321 is greater than or equal to the length of the second edge 322; the extension direction of the first edge 321 is consistent with the first direction.

[0058] In the embodiment of the present application, the first side 321 of the photovoltaic module 32 is the long side, and the direction of extension of the long side is consistent with the extension direction of the flexible cable 31. The short side of the photovoltaic module 32 is the extended end of the entire sunshade system. This structure has stronger wind resistance and higher stability. Furthermore, if the photovoltaic modules 32 need to cover the same length along the first direction, fewer photovoltaic modules 32 can be installed, which can save photovoltaic sunshade costs.

[0059] Optionally, in the embodiment of the present application, the length of the second side 322 is A, and there is a gap L between the photovoltaic assembly 32 and the building surface.

[0060] In the embodiment of the present application, in order to increase the power generation of the photovoltaic assembly 32, the photovoltaic unit can be driven to rotate. Setting A / 2<L<A can avoid the photovoltaic unit 3 from interfering with the building during the rotation process, and can enable the photovoltaic unit 3 to rotate flexibly according to actual needs. During the rotation of the photovoltaic unit 3, the gap L between the photovoltaic assembly 32 and the surface of the building can allow the photovoltaic assembly 32 to rotate freely, avoiding the interference between the rotating photovoltaic unit 3 and the building. Specifically, in actual applications, considering the actual installation and load-bearing issues, the photovoltaic unit 3 generally uses the center of the side length of the second side 322 along the axis of the first direction as the rotation axis. It can be understood that the gap between the building surface and the photovoltaic assembly 32 is greater than half the length of the second side 322 and less than the length of the second side 322 to achieve the rotation of the photovoltaic shading system.

[0061] Alternatively, as Figure 2 and Figure 3 As shown, the connection structure 33 may include: at least two side connectors 331, at least two side connectors 331 are arranged at intervals along the first direction, the side connectors 331 are long strip structures, and the two second sides 322 of the photovoltaic component 32 are respectively fixed on two different side connectors 331; and / or at least two point connectors 332, the point connectors 332 are distributed on two flexible cables 31, and multiple point connectors 332 fix the photovoltaic component 32 on the two flexible cables 31.

[0062] Optionally, if a single photovoltaic unit includes multiple photovoltaic assemblies 32 , the side connector 331 may connect two upper and lower adjacent photovoltaic assemblies 32 .

[0063] Optionally, in the embodiment of the present application, Figure 3 and Figure 4As shown, the side connector 331 can be used to connect the second side 322 to the two flexible cables 31, thereby securing the flexible cables 31 to the photovoltaic module 32. Specifically, the side connector 331 is an elongated structure, with both ends of the side connector 331 connected to the two flexible cables 31. The side connector 331 is also connected to the second side 322, thereby securing the photovoltaic module 32 to the flexible cables 31. The elongated side connector 331 and the second side 322 are aligned with each other, which has the beneficial effect of increasing the connection length, thereby improving the connection strength and stability. Furthermore, the two side connectors 331 are connected to the two second sides 322 of the same photovoltaic module 32 from both ends, securing the photovoltaic module 32 from both ends, specifically improving the stability of the connection between the photovoltaic module 32 and the flexible cables 31. The connector is configured to connect the first side 321 to the flexible cables 31, thereby securing the flexible cables 31 to the photovoltaic module 32. Specifically, the first side 321 can be connected to the flexible cable 31 through multiple point connectors 332. The multiple point connectors 332 can be evenly distributed on the first side 321. The point connectors 332 and the photovoltaic module 32 are connected through the first side 321 by point limiting.

[0064] In the present application, the first side 331 of the photovoltaic module 32 can be fixed by a point, and the second side 332 can be fixed by an edge. This structure has the advantages of being simple and reliable.

[0065] Further optionally, the long sides of the photovoltaic components 32 are fixed by points, and the short sides of the photovoltaic components are fixed by edges. This structure has high stability.

[0066] Optionally, in the embodiment of the present application, Figures 5 to 8 As shown, the side connector 331 includes a first clip 3311 and two first clamping members 3312 respectively located at both ends of the first clip 3311, one first clamping member 3312 clamps a flexible cable 31, and the other first clamping member 3312 clamps another flexible cable 31; a first groove 3313 is provided on the first clip 3311, and the opening of the first groove 3313 faces the photovoltaic component 32, and the two second edges 322 of the photovoltaic component 32 are respectively inserted into the first grooves 3313 of the two side connectors 331.

[0067] In the embodiment of the present application, the first clamping member 3311 is provided to achieve connection with the second side 322, and the two first clamping members 3312 are provided to achieve connection with the two flexible cables 31. Specifically, the two first clamping members 3312 are provided at both ends of the first clamping member 3311, and each clamping member clamps a flexible cable 31. The first clamping member 3311 is provided with at least one first groove 3313, which is provided to achieve connection with the second side 322. The first clamping member 3311 and the two first clamping members 3312 are provided to achieve connection with the side connector 331 and the second side 322, thereby achieving connection between the photovoltaic module 32 and the flexible cables 31. In the embodiment of the present application, the provision of the first groove 3313 can achieve connection with the second side 322 of the photovoltaic module 32, while also allowing the side connector 331 to achieve a flat design as a whole, which is more simple and beautiful.

[0068] Optionally, the first clamping member 3312 may include a first clamping cover 33121, a first clamping body 33122 and a first connecting portion 33123. The first clamping cover 33121 and the first clamping body 33122 cooperate to form a first connecting hole 33124 and a first mounting hole 33125. The first connecting hole 33124 is provided to realize the connection between the first clamping member 3312 and the flexible cable 31. The first mounting hole 33125 and the first connecting portion 33123 are cooperated to realize the locking between the first clamping cover 33121 and the first clamping body 33122, thereby realizing the connection of the first clip 3311 to the flexible cable 31.

[0069] In actual application, half of the first connection hole 33124 is formed on both the first clamping cover 33121 and the first clamping body 33122. In actual application, the first clamping cover 33121 and the first clamping body 33122 cooperate with each other, and the first connection holes of the two halves are aligned and matched to provide a connection position for the flexible cable 31. After the flexible cable 31 passes through the half of the first connection hole 33124 of the first clamping body 33122, the first clamping cover 33121 is then buckled. At this time, the first clamping cover 33121 and the first clamping body 33122 are buckled together, and the half of the first connection hole 33124 on the first clamping cover 33121 and the half of the first connection hole 33124 on the first clamping body 33122 are connected to form a complete first connection hole 33124, and the flexible cable 31 is located in the complete first connection hole 33124. The first connecting part 33123 cooperates with the first mounting hole 33125, and the first connecting part 33123 extends into the first mounting hole 33125, that is, penetrates into the first clamping body 33122 and the first clamping cover 33121, and then by tightening the first connecting part 33123 (which can be a bolt or a screw), the first clamping cover 33121 and the first clamping body 33122 clamp the flexible cable 31.

[0070] Optionally, in the embodiment of the present application, Figure 5 and Figure 8 As shown, there are multiple photovoltaic components 32, and two adjacent photovoltaic components 32 among the multiple photovoltaic components 32 share a side connector 331. Two first grooves 3313 are provided on the first clamping member 3311 of the shared side connector 331, and the openings of the two first grooves 3313 face opposite directions. The two second edges 322 close to each other in the two adjacent photovoltaic components 32 are respectively inserted into the two first grooves 3313.

[0071] In the embodiment of the present application, in actual application, the photovoltaic unit 3 may include a plurality of photovoltaic modules 32, and the plurality of photovoltaic modules 32 are arranged in sequence along the first direction. Two photovoltaic modules 32 adjacent to each other along the first direction in the same photovoltaic unit 3 share the same side connector 331. In order to achieve the connection of the side connector 331 to the second sides 322 of two adjacent photovoltaic modules 32, two first grooves 3313 are provided on the first clamping member 3311 of the shared side connector 331. It is understandable that in order to achieve the simultaneous fixed connection of the second sides 322 of two photovoltaic modules 32 adjacent to each other along the first direction, the opening directions of the two first grooves 3313 on the first clamping member 3311 of the shared side connector 331 are opposite, so that the two second sides 322 adjacent to each other in the two photovoltaic modules 32 adjacent to each other along the first direction are respectively inserted into the two first grooves 3313 on the same first clamping member 3311. In an embodiment of the present application, by opening two first grooves with opposite openings on a side connector, the connection of two photovoltaic components adjacent to each other along the first direction can be achieved simultaneously, which has the beneficial effects of reducing the weight of the photovoltaic unit, alleviating the load on the flexible cable, and reducing the installation complexity of the photovoltaic shading system.

[0073] In the embodiment of the present application, the second clamping member 3321 is provided to achieve connection with the first side 321, and the second clamping member 3322 is provided to connect with the flexible cable 31. Specifically, the second clamping member 3321 is provided with a second groove 3323, and the first side 321 of the photovoltaic module 32 is inserted into the second groove 3323, and the connection between the first side 321 and the second clamping member 3321 is achieved through the second groove 3323.

[0074] Furthermore, the provision of the first groove 3313 and the second groove 3323 enables the side connector 331 and the point connector 332 to be flattened as a whole, making the photovoltaic shading system more simple and beautiful.

[0075] Optionally, the second clamping member 3322 may include a second clamping cover 33221, a second clamping body 33222 and a second connecting portion 33223. The second clamping cover 33221 and the second clamping body 33222 cooperate to form a second connecting hole 33224. The second connecting hole 33224 is set to realize the connection between the second clamping member 33222 and the flexible cable 31. The second mounting hole 33225 and the second connecting portion 33223 are cooperated to realize the locking between the first clamping cover 33221 and the first clamping body 33222, thereby realizing the connection of the second clamping member 3321 to the flexible cable 31.

[0076] Specifically, half of a second connection hole 33224 is formed on each of the second clamping cover 33221 and the second clamping body 33222. In actual use, the second clamping cover 33221 cooperates with the second clamping body 33222, and the two half-holes of the second connection holes align and cooperate to provide a connection position for the flexible cable 31. After the flexible cable 31 passes through the half of the second connection hole 33224 of the second clamping body 33222, the second clamping cover 33221 is then buckled. At this time, the second clamping cover 33221 and the second clamping body 33222 are buckled together, and the half of the second connection hole 33224 on the second clamping cover 33221 and the half of the second connection hole 33224 on the second clamping body 33222 are connected to form a complete second connection hole 33224, and the flexible cable 31 is located in the complete second connection hole 33224. The second connecting part 33223 cooperates with the second mounting hole 33225, and the second connecting part 33223 extends into the second mounting hole 33225, that is, penetrates into the second clamping body 33222 and the second clamping cover 33221, and then by tightening the second connecting part 33223 (which can be a bolt or a screw), the second clamping cover 33221 and the second clamping body 33222 clamp the flexible cable 31.

[0077] Optionally, the structure of the second clamping member may refer to the description of the first clamping member 3312 above, and for the sake of brevity, it will not be repeated here.

[0078] Optionally, in the embodiment of the present application, flexible buffer portions are provided in both the first groove 3313 and the second groove 3323 , and the flexible buffer portions are in contact with the photovoltaic assembly 32 .

[0079] In the embodiment of the present application, the flexible buffer portion may have a certain degree of deformation capability. The flexible buffer portion is provided to, on the one hand, clamp the photovoltaic assembly 32 to prevent the photovoltaic assembly 32 from falling out of the first groove 3313 or the second groove 3323 during use, and on the other hand, to protect the photovoltaic assembly 32. In actual use, the hardness of the photovoltaic assembly 32 is relatively poor compared to the hardness of the edge connector 331 and the point connector 332. The flexible buffer portion is provided in the first groove 3313 and the second groove 3323. The first groove 3313 and the second groove 3323 are indirectly connected to the photovoltaic assembly 32 via the flexible buffer portion. The provision of the flexible buffer portion in the first groove 3313 and the second groove 3323 serves to protect the photovoltaic assembly 32.

[0080] Specifically, the flexible connecting member may be foam or silica gel, etc., and this embodiment does not impose any limitation on this.

[0081] Optionally, in an embodiment of the present application, there is a height difference between the first supporting frame 1 and the second supporting frame 2; or the first direction is the vertical direction of the building; or the first direction is the horizontal direction of the building; or the building includes a multi-story structure, and the first supporting frame 1 and the second supporting frame 2 are respectively located on different layers of the multi-story structure.

[0082] In the embodiment of the present application, there is a height difference between the first support frame 1 and the second support frame 2, and the photovoltaic unit 3 is arranged within the range of the height difference between the first support frame 1 and the second support frame 2. In practical applications, the first direction can be the vertical direction of the building. In this case, the photovoltaic unit 3 is arranged along the vertical direction of the building. The first direction can also be the horizontal direction of the building. In this case, the photovoltaic unit 3 is arranged along the horizontal direction of the building. In addition, the building may include a multi-layer structure, and the first support frame 1 and the second support frame 2 may be located at different layers of the multi-layer structure. It can be understood that in this case, the photovoltaic unit 3 arranged between the first support frame 1 and the second support frame 2 will be able to cover the building with different layers of support members.

[0083] Optionally, in the embodiment of the present application, Figure 6 As shown, the photovoltaic unit 3 further includes: at least one auxiliary support member 34 , which is located on the backlight side of the photovoltaic assembly 32 , and both ends of the auxiliary support member 34 are respectively connected to the two flexible cables 31 .

[0084] In the embodiment of the present application, the auxiliary support member 34 is provided to provide support for the photovoltaic module 32 on the backlight side of the photovoltaic module 32, thereby preventing the connection strength between the flexible cable 31 and the photovoltaic module 32 from being insufficient during use, which would affect the operation of the photovoltaic module 32 when the photovoltaic module 32 is subjected to external forces. Specifically, the ends of the auxiliary support member 34 are respectively connected to the flexible cable 31. The cooperation between the flexible cable 31 and the auxiliary support member 34 improves the support strength of the photovoltaic unit 3.

[0085] Furthermore, optionally, the auxiliary support member 34 is provided to further enhance the support strength of the flexible cables 31 on the photovoltaic module 32. Specifically, the auxiliary support member 34 is connected between the two flexible cables 31, and the preset angle between the auxiliary support member 34 and the flexible cables 31 is not equal to 90°. Specifically, the auxiliary support member 34 can be a scissor-shaped auxiliary support member 34 or an auxiliary support member 34 that is inclined in at least a certain direction.

[0086] It should be noted that if Figure 7 As shown, the auxiliary support member 34 can be connected to the flexible cable 31 through the side connector 331, and the two ends of the auxiliary support member 34 that are opposite to each other along the first direction are respectively connected to the two side connectors 331. The other end of the auxiliary support member 25 is connected to another first clamping member 412, and the preset angle between the auxiliary support member 25 and the flexible cable 22 is not equal to 90°. Specifically, the auxiliary support member can also be a scissor-shaped auxiliary support member 25 or an auxiliary support member 25 that is inclined in at least a certain direction. It should be noted that there is a preset angle between the auxiliary support member 34 and the flexible cable 31, and the preset angle is greater than 90°, or the preset angle is less than 90°. It can be understood that the auxiliary support member 34 provides oblique support between the two flexible cables 31, which has the beneficial effect of improving the wind resistance performance of large-span photovoltaic systems.

[0087] Optionally, the auxiliary support member 34 may also be a flexible cable.

[0088] Alternatively, as Figure 7 As shown, the first clamping member has two holes, one hole is used to pass the flexible cable, and the other hole is used to pass the auxiliary support member 34.

[0089] Optionally, in the embodiment of the present application, Figure 11 As shown, a photovoltaic assembly 32 corresponds to one auxiliary support member 34 , or a photovoltaic unit 3 corresponds to one auxiliary support member 34 .

[0090] In the embodiment of the present application, the photovoltaic modules 32 may correspond to the auxiliary support members 34 on a one-to-one basis, that is, each photovoltaic module 32 may be provided with an auxiliary support member 34 on the backlight side. Alternatively, one photovoltaic unit 3 may correspond to one auxiliary support member 34. Specifically, when a photovoltaic unit 3 is provided with one photovoltaic module 32, the auxiliary support member 34 may be provided on the backlight side of one photovoltaic module 32. When a photovoltaic unit 3 is provided with multiple photovoltaic modules 32, the auxiliary support member 34 may be provided on the backlight side of multiple photovoltaic modules 32.

[0091] Optionally, in an embodiment of the present application, it also includes: a first rotating mechanism 4 and a second rotating mechanism 5 corresponding to the photovoltaic unit 3, the photovoltaic unit 3 includes a first end and a second end, the first rotating mechanism 4 is connected to the first end, the first rotating mechanism 4 is located between the first support frame 1 and the first end, the second rotating structure is connected to the second end, the second rotating mechanism 5 is located between the second support frame 2 and the second end, and the first rotating mechanism 4 and the second rotating mechanism 5 jointly drive the photovoltaic unit 3 to rotate.

[0092] In the embodiment of the present application, the first rotating mechanism 4 and the second rotating mechanism 5 are configured to rotate the photovoltaic unit 3. Specifically, the first rotating mechanism 4 is connected to the first end and is located between the first support frame 1 and the first end. The second rotating mechanism 5 is connected to the second end and is located between the second support frame 2 and the second end. The first rotating mechanism 4 and the second rotating mechanism 5 can drive the photovoltaic unit 3 to rotate. It will be understood that driving the photovoltaic unit 3 to rotate indirectly drives the photovoltaic assembly 32 disposed in the photovoltaic unit 3 to rotate.

[0093] In practical applications, increasing the power generation of photovoltaic modules 32 can be achieved by adjusting the angle at which sunlight directly strikes photovoltaic modules 32. Specifically, direct sunlight strikes photovoltaic modules 32, thereby increasing the amount of solar radiation received by photovoltaic modules 32 and improving their overall power generation. Furthermore, when the external environment experiences strong winds, the first rotating mechanism 4 and the second rotating mechanism 5 can be used to adjust the angle of photovoltaic modules 3 so that photovoltaic modules 32 are parallel to the wind load direction, reducing the out-of-plane loads on the photovoltaic modules 32 and thus ensuring the safety of the photovoltaic modules 32 and the photovoltaic shading system. Through the coordinated action of the first rotating mechanism 4 and the second rotating mechanism 5, the photovoltaic shading system blocks sunlight to prevent overheating in the building's interior without affecting natural lighting. In addition to blocking sunlight, the system also prevents glare, regulates air flow, and blocks sightlines. The photovoltaic shading system can rotate photovoltaic modules 3 using the first rotating mechanism 4 and the second rotating mechanism 5, depending on the building's latitude, radiation intensity, azimuth, and external factors. This can significantly reduce air conditioning loads, save building energy consumption, and maximize power generation efficiency.

[0094] Optionally, the first rotating mechanism 4 and the second rotating mechanism 5 may include a tracking component and a driving component. The first rotating mechanism 4 and the second rotating mechanism 5 may be self-powered by a string and equipped with a lithium battery backup to provide power. The tracking component may track the movement of the sun in real time so that sunlight directly hits the photovoltaic component 32 in the photovoltaic unit 3, thereby increasing the amount of solar radiation received by the photovoltaic component 32.

[0095] Optionally, the flexible cable 31 may also include two end plates, the two end plates being arranged relative to each other along a first direction, the two flexible cables 31 extending along the first direction, and the ends of the flexible cables 31 along the first direction being connected to the two end plates, respectively. The first rotating mechanism 4 is arranged between one end plate and the first support frame 1, the second rotating mechanism 5 is arranged between the other end plate and the second support frame 2, the cable anchor is connected between the flexible cable 31 and one end plate, and the regulator cable anchor is connected between the flexible cable 31 and the other end plate. The end plates and the flexible cables 31 are interconnected to form a flexible ring, and the photovoltaic module 32 is arranged within the flexible ring. The two end plates are arranged relative to each other along the first direction, and the end plates extend along the second direction. The two flexible cables 31 extend along the first direction. It can be understood that one end plate, one flexible cable 31, another end plate, and another flexible cable 31 are connected end to end in sequence to form a flexible ring. One end of the flexible cable 31 is fixed to the end plate using a cable anchor, and the other end of the flexible cable 31 is fixed to another end plate using an adjuster cable anchor, thereby forming a planar support structure, which is supported by the flexible cable 31 and is connected to the full-length frame through two end plates arranged opposite to each other along the first direction.

[0096] In practical applications, the flexible cable 31 and an end plate are first connected through a cable anchor, and then the flexible cable 31 and another end plate are connected through an adjuster cable anchor. Then, the preload force of the flexible cable 31 is adjusted through the adjuster cable anchor according to actual conditions.

[0097] Furthermore, the floor height of a general building will vary depending on the type of building, most of which are 3 meters, 4.5 meters, 5 meters, etc., while the photovoltaic module 32 is a standard product, and its length dimension is generally about 2.28 meters. Due to the mismatch between the two sizes, a series of installation problems are caused. The above-mentioned support method using flexible cables 31 can meet the large-span installation of photovoltaic modules 32, and several photovoltaic modules 32 can be arranged in the direction of the flexible cables 31, which has the beneficial effect of making full use of the building surface size while saving costs.

[0098] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.
