[0003] In related technologies, photovoltaic brackets often suffer from poor structural stability. When installed on a roof, they may be damaged or deformed due to wind loads, thus affecting the stable operation of the photovoltaic system. Utility Model Content

[0004] The problem addressed in this disclosure is: how to improve the structural stability of photovoltaic support structures.

[0005] To address the aforementioned issues, this disclosure provides a flexible photovoltaic bracket and a photovoltaic system.

[0006] In a first aspect, this disclosure provides a photovoltaic support structure, including a load-bearing component, diagonal braces, and connecting rods. Two diagonal braces are arranged at an angle with their openings facing downwards. The lower ends of the two diagonal braces are connected to the roof, and the upper ends are connected to the load-bearing component. The load-bearing component is used to support photovoltaic modules. The diagonal braces are provided with first connecting holes, and the connecting rods are provided with a plurality of second connecting holes arranged sequentially along their extension direction. The connecting rods are respectively connected to the first connecting holes of the two diagonal braces through two second connecting holes, so that the two diagonal braces are fixed at the included angle.

[0007] Optionally, it also includes a first connector, through which the diagonal brace is connected to the load-bearing assembly.

[0008] Optionally, the first connector includes bolts, which are sequentially passed through the diagonal brace and the load-bearing assembly to fix the diagonal brace and the load-bearing assembly together; or, the first connector includes a hinge shaft, which is sequentially passed through the diagonal brace and the load-bearing assembly to rotatably connect the diagonal brace and the load-bearing assembly.

[0009] Optionally, it also includes a clamp for fixing to the roof, the clamp being connected to the lower end of the diagonal brace via a second connector.

[0010] Optionally, the clamp includes a clamp body and a connecting block detachably connected to the clamp body. The clamp body is used to clamp onto the ribs of the roof, and the connecting block is connected to the lower end of the diagonal brace via the second connector.

[0011] Optionally, the connecting block includes a base plate and two vertical plates spaced apart from the base plate, the two vertical plates being respectively connected to the lower end of the diagonal brace, and the clamp body being connected to the base plate.

[0012] Optionally, the base plate is provided with a first through hole, the clamp body is provided with a second through hole, and the photovoltaic bracket further includes a fastener, which passes through the first through hole and the second through hole.

[0013] Optionally, the load-bearing component includes a connecting seat, and the upper ends of the two diagonal braces are respectively connected to the connecting seat. The connecting seat is used for the main beam to be rotatably installed around its own center line.

[0014] Optionally, it also includes a drive mechanism for driving the main beam to rotate. The drive mechanism includes a support rod, a linear push rod, and a swing arm. The support rod is connected to the diagonal brace. One end of the linear push rod is connected to the support rod. One end of the swing arm is hinged to the linear push rod. The other end of the swing arm is connected to the main beam.

[0015] Optionally, a plurality of connecting seats are rotatably connected to the main beam, and the plurality of connecting seats are arranged sequentially along the extension direction of the main beam. Each connecting seat is connected to two diagonal braces, and the two ends of the brace are respectively connected to two diagonal braces spaced apart along the extension direction of the main beam.

[0016] Optionally, it may also include a reinforcing component, which includes a reinforcing rod, the lower end of which is mounted on the roof and the upper end of which is connected to the diagonal brace or the connecting rod.

[0017] Optionally, the reinforcing assembly includes at least two reinforcing rods, the lower ends of which are connected and used for joint installation on the roof. Each reinforcing rod has a plurality of third connecting holes arranged sequentially along its extension direction. The reinforcing rod is connected to the first connecting hole or the second connecting hole through the third connecting hole, and the two reinforcing rods and the connecting rod form a triangular structure.

[0018] Optionally, a plurality of reinforcing components are connected to the connecting rod, and the plurality of reinforcing components are arranged sequentially along the extension direction of the connecting rod.

[0019] Secondly, this disclosure provides a photovoltaic system, including photovoltaic modules and a photovoltaic bracket as described above, wherein the photovoltaic modules are mounted on the photovoltaic bracket.

[0020] The beneficial effects of the photovoltaic bracket disclosed herein are as follows: Since the two diagonal braces are set at an angle with their openings facing downwards, the lower ends of the two diagonal braces are connected to the roof, and the upper ends are connected to the load-bearing components. Furthermore, the two second connecting holes of the connecting rod are connected to the first connecting holes of the two diagonal braces, so the connecting rod and the two diagonal braces can form an A-shaped structure, thereby improving the structural stability of the photovoltaic bracket. When the system is subjected to wind loads, the bracket is not easily damaged or deformed, which is conducive to ensuring the stable operation of the photovoltaic system. In addition, since there are multiple second connecting holes on the connecting rod arranged sequentially along the extension direction of the connecting rod, even if the angle between the two diagonal braces is adjusted according to the spacing of the ribs, the connecting rod can still select different two second connecting holes to connect with the diagonal braces, so as to ensure that the photovoltaic bracket can adapt to different rib spacings and thus adapt to different roof installation environments.

[0040] It should be noted that the terms "one" and "more" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0041] This disclosure provides a photovoltaic support bracket and a photovoltaic system to improve the structural stability of the photovoltaic support bracket. Detailed descriptions are provided below with reference to specific embodiments.

[0042] like Figure 1 and Figure 2 As shown in the figure, a photovoltaic bracket 100 provided in this embodiment includes a load-bearing component 1, diagonal braces 2, and connecting rods 3. The two diagonal braces 2 are arranged at an angle with their openings facing downwards. The lower ends of the two diagonal braces 2 are used to connect to the roof 300, and the upper ends are connected to the load-bearing component 1. The load-bearing component 1 is used to support the photovoltaic module 200. The diagonal braces 2 are provided with a first connecting hole, and the connecting rod 3 is provided with a plurality of second connecting holes 31 arranged sequentially along its extension direction. The connecting rod 3 is connected to the first connecting holes of the two diagonal braces 2 through the two second connecting holes 31 respectively, so that the two diagonal braces 2 are fixed at the included angle.

[0043] Specifically, the lower end of the diagonal brace 2 can be connected to the corrugated strip 301 of the roof 300. For example, when the roof 300 is a corrugated steel roof, the corrugated strip 301 can be the corrugated strip of the corrugated steel roof. Since the corrugated strip 301 usually has higher strength than other parts of the roof 300, connecting the lower end of the diagonal brace 2 to the corrugated strip 301 can relatively reduce damage to the roof 300. Furthermore, when installing the photovoltaic bracket 100 onto the roof 300, it is often necessary to adjust the included angle between the two diagonal braces 2 according to different corrugated strip spacings to ensure that the lower ends of the two diagonal braces 2 are connected to two different corrugated strips to reduce damage to the roof 300. For example, see [reference needed]. Figure 3 and Figure 4 ,because Figure 3 The spacing between the two diagonal braces 2 on the rib 301 is greater than Figure 4The spacing between the two diagonal braces 2 on the rib 301, therefore Figure 3 The included angle between the two diagonal braces 2 should be greater than 2. Figure 4 The included angle between the two diagonal braces 2.

[0044] Specifically, the first connecting hole can be located at the middle of the diagonal brace 2 along its length. The multiple second connecting holes 31 refer to two or more second connecting holes 31. Furthermore, for the corresponding connection between the two second connecting holes 31 and the two first connecting holes, for example, bolts can be used to sequentially pass through the second connecting holes 31 and the first connecting holes to achieve the connection; this is not limited here.

[0045] In this embodiment, since the two diagonal braces 2 are set at an angle with their openings facing downwards, the lower ends of the two diagonal braces 2 are connected to the roof 300, and the upper ends are connected to the load-bearing component 1. The two second connecting holes 31 of the connecting rod 3 are connected to the first connecting holes of the two diagonal braces 2. Therefore, the connecting rod 3 and the two diagonal braces 2 can form an A-shaped structure to improve the structural stability of the photovoltaic bracket 100. When the system is subjected to wind load, the bracket is not easily damaged or deformed, which is conducive to ensuring the stable operation of the photovoltaic system. In addition, since there are multiple second connecting holes 31 on the connecting rod 3 arranged sequentially along the extension direction of the connecting rod 3, even if the angle between the two diagonal braces 2 is adjusted according to the spacing of the ribs, the connecting rod 3 can still select two different second connecting holes 31 to connect with the diagonal braces 2 to ensure that the photovoltaic bracket 100 can adapt to different rib spacings, thereby adapting to different roof installation environments.

[0046] Optionally, such as Figure 2 As shown, the photovoltaic bracket 100 also includes a first connector 5, and the diagonal brace 2 is connected to the load-bearing component 1 through the first connector 5.

[0047] In this optional embodiment, the diagonal brace 2 is connected to the bearing assembly 1 via the first connector 5, and its angle can be adjusted relative to the bearing assembly 1, thereby changing the included angle between the two diagonal braces 2.

[0048] Optionally, such as Figure 2 As shown, the first connecting member 5 includes bolts, which are sequentially inserted through the diagonal brace 2 and the bearing assembly 1 to fix the diagonal brace 2 and the bearing assembly 1.

[0049] In this optional embodiment, by designing the first connector 5 as a bolt, and having the bolt sequentially pass through the diagonal brace 2 and the load-bearing component 1, a bolted connection is formed between the diagonal brace 2 and the load-bearing component 1. When it is necessary to adjust the included angle between the two diagonal braces 2, the bolt can be loosened to adjust the position of the diagonal brace 2 relative to the load-bearing component 1, thereby changing the included angle between the two diagonal braces 2.

[0050] Optionally, such as Figure 2 As shown, the first connecting member 5 includes a hinge shaft, which passes through the diagonal brace 2 and the load-bearing component 1 in sequence, so that the diagonal brace 2 and the load-bearing component 1 are rotatably connected.

[0051] In this optional embodiment, by designing the first connecting member 5 as a hinge shaft, and having the hinge shaft pass through the diagonal brace 2 and the load-bearing component 1 in sequence, a rotational connection is formed between the diagonal brace 2 and the load-bearing component 1. When it is necessary to adjust the included angle between the two diagonal braces 2, the diagonal brace 2 can be rotated relative to the load-bearing component 1 to change the included angle between the two diagonal braces 2.

[0052] Optionally, such as Figure 4 As shown, the photovoltaic bracket 100 also includes a clamp 4, which is used to fix the bracket to the roof 300. The clamp 4 is connected to the lower end of the diagonal brace 2 through a second connector 6.

[0053] Specifically, the second connecting member 6 can be a bolt or a hinge shaft. For example, when the second connecting member 6 is a bolt, the bolt can be sequentially inserted into the clamp 4 and the diagonal brace 2 to form a bolted connection between the two. For example, when the second connecting member 6 is a hinge shaft, the hinge shaft can be sequentially inserted into the clamp 4 and the diagonal brace 2 to form a hinge between the two.

[0054] In this optional embodiment, since the clamp 4 is connected to the lower end of the diagonal brace 2 through the second connector 6, the angle of the clamp 4 relative to the lower end of the diagonal brace 2 can be adjusted. For example, when the second connector 6 is a bolt, the angle of the clamp 4 relative to the diagonal brace 2 can be adjusted by loosening the bolt, thereby changing the posture of the clamp 4. Therefore, when the included angle between the two diagonal braces 2 is adjusted, the angle of the clamp 4 can be adjusted accordingly to ensure that the clamp 4 as a whole can be perpendicular to the roof surface 300, thereby facilitating better clamping of the roof joists.

[0055] Optionally, the clamp 4 includes a clamp body 41 and a connecting block 42 detachably connected to the clamp body 41. The clamp body 41 is used to clamp onto the ribs 301 of the roof 300, and the connecting block 42 is connected to the lower end of the diagonal brace 2 through the second connecting member 6.

[0056] The clamp body 41 is used to clamp the ribs 301 of the roof 300, which is a conventional device in the art. Therefore, the structure of the clamp body 41 will not be described in detail in this disclosure.

[0057] In this optional embodiment, by detachably connecting the clamp body 41 and the connecting block 42, different models of clamp bodies 41 can be easily disassembled and replaced, thereby adapting to roof joists of different shapes and improving the adaptability of this photovoltaic bracket 100.

[0058] Optionally, such as Figure 5 and Figure 6 As shown, the connecting block 42 includes a base plate 421 and two vertical plates 422 spaced apart from the base plate 421. The two vertical plates 422 are respectively connected to the lower end of the diagonal brace 2. The clamp body 41 is connected to the base plate 421.

[0059] Specifically, the second connector 6 can be sequentially inserted through the two vertical plates 422 and the diagonal brace 2 to achieve the connection between the clamp 4 and the lower end of the diagonal brace 2.

[0060] In this optional embodiment, by designing the connecting block 42 as a base plate 421 and two vertical plates 422, the structure is simple and reliable, which helps to reduce the installation complexity of the photovoltaic bracket 100.

[0061] Optionally, such as Figure 5 and Figure 6 As shown, the base plate 421 is provided with a first through hole 4211, the clamp body 41 is provided with a second through hole, and the photovoltaic bracket 100 also includes a fastener 7, which passes through the first through hole 4211 and the second through hole.

[0062] Specifically, fastener 7 can be a bolt.

[0063] In this optional embodiment, by passing the fastener 7 through the first through hole 4211 of the base plate 421 and the second through hole of the clamp body 41, the base plate 421 and the clamp body 41 can be detachably connected, thereby facilitating the replacement of different clamp bodies 41 to adapt to roof ribs of different shapes.

[0064] Optionally, such as Figure 7 and Figure 8 As shown, the load-bearing component 1 includes a connecting seat 11, and the upper ends of the two diagonal braces 2 are respectively connected to the connecting seat 11. The connecting seat 11 is used for the main beam 201 to be rotated and installed around its own center line.

[0065] Specifically, purlins 202 can be installed on the main beam 201, and the main beam 201 and purlins 202 can be used to fix the photovoltaic module 200 together. In addition, the first connector 5 can be sequentially inserted into the connector 11 and the diagonal brace 2 to realize the connection between the diagonal brace 2 and the load-bearing component 1.

[0066] Additionally, the load-bearing assembly 1 may also include a swivel bearing 12, through which the main beam 201 can be rotatably mounted on the connecting seat 11, for example, referring to... Figure 9The rotating bearing 12 may include an outer ring 121 and an inner ring 122. The outer ring 121 is connected to the connecting seat 11, and the inner ring 122 is rotatably fitted inside the outer ring 121. A connecting hole is defined in the inner ring 122, and the main beam 201 passes through the connecting hole, thereby allowing the main beam 201 to rotate within the outer ring 121 with the inner ring 122, thus realizing the rotatable mounting of the main beam 201 on the connecting seat 11. Furthermore, the cross-section of the connecting hole can be adapted to the cross-sectional shape of the main beam 201, for example, both can be square.

[0067] It should be noted that the centerline of the main beam 201 is the centerline of the main beam 201 that is parallel to its length direction.

[0068] In this optional embodiment, the connecting seat 11 allows the main beam 201 to be rotatably installed around its own centerline. In this way, when the main beam 201 rotates, it can drive the photovoltaic module 200 to rotate, thereby changing the tilt angle of the photovoltaic module 200, which is conducive to maximizing the absorption of solar energy and improving power generation efficiency.

[0069] Optionally, such as Figure 7 and Figure 10 As shown, the photovoltaic support 100 also includes a drive mechanism 8 for driving the main beam 201 to rotate. The drive mechanism 8 includes a support rod 81, a linear push rod 82, and a swing arm 83. The support rod 81 is connected to the diagonal brace 2. One end of the linear push rod 82 is connected to the support rod 81. One end of the swing arm 83 is hinged to the linear push rod 82. The other end of the swing arm 83 is connected to the main beam 201.

[0070] Specifically, the swing arm 83 can be fastened to the main beam 201 by a clamp, and one end of the linear push rod 82 can be hinged to the support rod 81.

[0071] In this optional embodiment, when the linear push rod 82 extends or retracts, the linear push rod 82 can drive the main beam 201 to rotate around its own center line through the swing arm 83 to adjust the tilt angle of the photovoltaic module 200, thereby realizing automatic adjustment of the tilt angle according to the illumination conditions and ensuring better power generation efficiency.

[0072] Optionally, such as Figure 7 and Figure 10 As shown, a plurality of connecting seats 11 are rotatably connected to the main beam 201. The plurality of connecting seats 11 are arranged sequentially along the extension direction of the main beam 201. Each connecting seat 11 is connected to two diagonal braces 2. The two ends of the support rod 81 are respectively connected to two diagonal braces 2 spaced apart along the extension direction of the main beam 201.

[0073] It should be noted that "multiple connectors 11" means that the number of connectors 11 can be two or more.

[0074] In this optional embodiment, it is understood that when the support rod 81 is connected to only one diagonal brace 2, the reaction force generated when the linear push rod 82 extends and retracts will be transmitted to the roof 300 through the support rod 81 and the diagonal brace 2. At this time, the reaction force transmitted to the roof 300 by the diagonal brace 2 may be too large and damage the roof 300. However, in this solution, since the two ends of the support rod 81 are respectively connected to two diagonal braces 2 spaced apart along the extension direction of the main beam 201, the reaction force obtained by the support rod 81 will be transmitted to the roof 300 through the two diagonal braces 2 respectively, thereby dispersing the reaction force of the linear push rod 82. This avoids the reaction force transmitted to the roof 300 by a single diagonal brace 2 being too high and damaging the roof, thus ensuring the structural safety of the roof 300.

[0075] Optionally, such as Figure 11 and Figure 12 As shown, the photovoltaic bracket 100 also includes a reinforcing component 9, which includes a reinforcing rod 91. The lower end of the reinforcing rod 91 is installed on the roof 300, and the upper end is connected to the diagonal brace 2 or the connecting rod 3.

[0076] In this optional embodiment, by adding the reinforcing rod 91, the number of connection points between the photovoltaic bracket 100 and the roof 300 can be relatively increased, which helps to disperse the reaction force transmitted from the photovoltaic bracket 100 to the roof 300, thereby preventing the roof 300 from being damaged by pressure. In addition, it also helps to improve the connection between the photovoltaic bracket 100 and the roof 300, thereby improving the wind resistance performance of the photovoltaic bracket 100.

[0077] Optionally, such as Figure 11 and Figure 12 As shown, the reinforcing component 9 includes at least two reinforcing rods 91. The lower ends of the at least two reinforcing rods 91 are connected and used to be installed together on the roof 300. Each reinforcing rod 91 is provided with a plurality of third connecting holes 911 arranged sequentially along its extension direction. The reinforcing rod 91 is connected to the first connecting hole or the second connecting hole 31 through the third connecting hole 911. The two reinforcing rods 91 and the connecting rod 3 form a triangular structure.

[0078] It should be noted that "multiple third connecting holes 911" refers to two or more third connecting holes 911. Regarding the connection of the third connecting hole 911 with the first connecting hole or the second connecting hole 31, it can be understood that the third connecting hole 911 can connect to the first connecting hole, thus fixing the reinforcing rod 91 relative to the diagonal brace 2. The third connecting hole 911 can also connect to the second connecting hole 31, thus fixing the reinforcing rod 91 relative to the connecting rod 3. Furthermore, for two reinforcing rods 91, the third connecting holes 911 of the two reinforcing rods 91 can be connected to the two second connecting holes 31 of the connecting rod 3, respectively. The third connecting holes 911 of the two reinforcing rods 91 can also be connected to the first connecting holes of the two diagonal braces 2, respectively; no specific limitations are made here. Specifically, bolts can be used to sequentially pass through the third connecting hole 911 and the first connecting hole or the second connecting hole 31 to achieve the connection. Additionally, a clamp 4 can be provided at the lower end of the reinforcing rod 91, and the lower end of the reinforcing rod 91 can be fixed to the rib 301 of the roof 300 by the clamp 4.

[0079] In this optional embodiment, the two reinforcing rods 91 can form a triangular structure with the connecting rod 3 to further enhance the structural stability of the photovoltaic bracket 100, thereby improving the wind resistance and lateral displacement resistance of the photovoltaic bracket 100. In addition, since there are multiple third connecting holes 911 on the two reinforcing rods 91, even if the included angle of the two diagonal braces 2 is adjusted, resulting in a change in the height of the first connecting hole and the second connecting hole 31, the reinforcing rod 91 can still select third connecting holes 911 of different heights to connect with the first connecting hole and the second connecting hole 31, so that the reinforcing rod 91 can adapt to different included angles of the diagonal braces 2, improving the versatility of the reinforcing rod 91.

[0080] Optionally, such as Figure 13 As shown, a plurality of reinforcing components 9 are connected to the connecting rod 3, and the plurality of reinforcing components 9 are arranged sequentially along the extension direction of the connecting rod 3.

[0081] It should be noted that "multiple reinforcing components 9" means that the number of reinforcing components 9 can be two or more. Specifically, in this embodiment, the number of reinforcing components 9 is two.

[0082] In this optional embodiment, multiple reinforcing components 9 can form more triangular structures with the connecting rod 3 to further enhance the structural stability of the photovoltaic bracket 100, thereby improving its wind resistance and lateral displacement resistance, making it easier to cope with more severe weather such as typhoons. At the same time, multiple reinforcing components 9 can further increase the number of connection points between the photovoltaic bracket 100 and the roof 300, thereby further dispersing the reaction force transmitted from the photovoltaic bracket 100 to the roof 300, which is more conducive to ensuring the structural safety of the photovoltaic bracket 100 and the roof 300.

[0083] like Figure 14As shown in the figure, a photovoltaic system provided in this disclosure includes a photovoltaic module 200 and a photovoltaic bracket 100 as described above, wherein the photovoltaic module 200 is mounted on the photovoltaic bracket 100.

[0084] Specifically, the photovoltaic module 200 can be mounted on the photovoltaic bracket 100 via the main beam 201 and the purlin 202. Furthermore, as... Figure 14 As shown, roof 300 can be the roof of building 400.

[0085] In this embodiment, since the photovoltaic system includes the photovoltaic bracket 100 described above, it possesses all the beneficial effects brought about by all embodiments of the photovoltaic bracket 100 described above, which will not be repeated here.

[0086] While the above disclosure is provided, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this disclosure.
