[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0037] The core of the utility model is to provide a photovoltaic module support structure and a photovoltaic system, which can effectively prevent excessive deformation of the photovoltaic modules.
[0038] The photovoltaic component support structure provided by the utility model is applied to a photovoltaic component tracking bracket and is used for being connected to the back side of the photovoltaic component.
[0039] For a specific example of the photovoltaic module support structure provided by this utility model, please refer to Figures 1 to 9 , including a first purlin 1, a second purlin 2 and a positioning plate 3.
[0040] The first purlin 1 extends along a first direction X, with multiple first purlins 1 arranged sequentially along a second direction Y. The second purlin 2 extends along the second direction Y, with both ends of the second purlin 2 respectively fixed to two adjacent first purlins 1 in the second direction Y. The positioning plate 3 is fixedly connected to the first purlin 1. The positioning plate 3 and the first purlin 1 clamp a portion of the second purlin 2 and are plugged into the second purlin 2 along a third direction Z.
[0041] It should be noted that, in this embodiment, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In other embodiments, they may also be at other angles.
[0042] When applied, Figure 1 As shown, the frame of the photovoltaic module 4 includes two first frames 41 extending along a first direction X and two second frames 42 extending along a second direction Y. The first frames 41 are longer than the second frames 42, and the multiple photovoltaic modules 4 are arranged in sequence along the second direction Y. The first purlin 1 is fixedly connected to the back surface of the first frame 41 and covers part of the back surface of the first frame 41. The second purlin 2 can be used to reinforce the space between the two first frames 41 of the photovoltaic module 4.
[0043] In this embodiment, the first purlin 1 is used to be connected to the frame of the photovoltaic module 4, and the adjacent frame can be reinforced by adding a second purlin 2 connected to the adjacent first purlin 1. When the photovoltaic module is subjected to frontal pressure, the second purlin 2 can provide support from the back of the photovoltaic module 4. On this basis, a positioning plate 3 is also added. The positioning plate 3 and the first purlin 1 clamp and fix the second purlin 2, and are plugged into the second purlin 2. The end limit and connection strength of the second purlin 2 can be strengthened from different directions. The movement or deformation of the end of the second purlin 2 is avoided, thereby improving the bending resistance of the second purlin 2. Specifically, when the photovoltaic module is deformed, the second purlin 2 can support the back of the originally suspended photovoltaic module 4 (specifically the back glass), avoiding excessive deformation or bursting of the photovoltaic module 4, and improving the bending resistance and support capacity of the photovoltaic module 4. At the same time, the plug-in cooperation between the positioning plate 3 and the second purlin 2 can avoid the second purlin 2 from moving or deforming relative to the first purlin 1, further increasing the front load-bearing capacity of the photovoltaic module 4.
[0044] On the second purlin 2, if Figure 2 、 Figure 4 and Figure 5 As shown, the second purlin 2 includes a first side plate 21 , a second side plate 22 and a third side plate 23 which are sequentially arranged and fixedly connected along the third direction Z.
[0045] Among them, Figure 2As shown, in the second direction Y, the end of the first side panel 21 extends out of the second side panel 22 and forms a first connecting portion 211, and the end of the third side panel 23 extends out of the second side panel 22 and forms a third connecting portion 231. At this time, the first connecting portion 211, the end surface of the second side panel 22 in the second direction Y, and the third connecting portion 231 form a notch for cooperating with the first purlin 1 for installation. In the third direction Z, the first purlin 1 is sandwiched between the first connecting portion 211 and the third connecting portion 231. At this time, the first purlin 1 supports the first side panel 21 and the third side panel 23, facilitating the assembly of the first purlin 1 and the second purlin 2. At the same time, the first purlin 1 can be used to prevent the first side panel 21 and the third side panel 23 from being deformed or twisted, thereby improving the bending resistance of the second purlin 2.
[0046] Among them, Figure 4 As shown, specifically, the first side panel 21, the second side panel 22, and the third side panel 23 form an I-shaped purlin. The second side panel 22 provides good support for the first and third side panels 21, 23, thereby reducing the risk of deformation of the first and third side panels 21, 23. In addition, a rounded structure 221 is provided on the end surface of the second side panel 22 in the second direction Y, where it interfaces with the first and third side panels 21, 23, to reduce stress.
[0047] Of course, in other embodiments, the second purlin 2 may also be U-shaped, in which case the second side panel 22 is fixed to one end of the first side panel 21 and one end of the second side panel 22 in the first direction X. Alternatively, the second purlin 2 may also be L-shaped, in which case the second purlin 2 may include only the first side panel 21 and the second side panel 22 without the third side panel 23; or may include only the second side panel 22 and the third side panel 23 without the first side panel 21.
[0048] In the first purlin 1, if Figure 3 As shown, in the second direction Y, the first purlin 1 includes a second side panel 12 and two first side panels 11. The two first side panels 11 are arranged sequentially along the second direction Y and are respectively fixedly connected to the second side panels 12. The first side panels 11 and the second side panels 12 are arranged sequentially along the third direction Z. Specifically, in the first purlin 1, the two first side panels 11 are connected to the ends of the second side panels 12 via the third side panels 13 to form an "X"-shaped structure. In this case, the two first side panels 11 serve as the two flanges of the "X"-shaped structure.
[0049] In the assembly of the second purlin 2 and the first purlin 1, as Figure 2 and Figure 3As shown, the two first side panels 11 are respectively connected to the first connecting portions 211 of the two second purlins 2, and the third connecting portions 231 of the two second purlins 2 are simultaneously connected to a second side panel 12. At this point, the connection locations of the first side panels 21 and the third side panels 23 on the first purlin 1 can be separated to facilitate assembly. Because there is a certain distance between the first side panels 11 and the second side panels 12 in the third direction Z, space is reserved for the installation and placement of the bolts connecting the third side panels 23 and the second side panels 12.
[0050] Among them, Figure 3 As shown, the first connecting portion 211 is sandwiched between the first purlin 1 and the first frame 41 of the photovoltaic assembly 4 and is fixed by a first bolt 14 , which is convenient for assembly.
[0051] In the positioning plate 3, as Figures 7 to 9 As shown, a hook 31 is provided on the positioning plate 3, and a socket 233 penetrating along the third direction Z is provided on the third connecting portion 231 of the second purlin 2. The hook 31 is plugged into the socket 233 for easy assembly.
[0052] Among them, Figure 5 , Figure 8 and Figure 9 As shown, the hook 31 includes a first hook 311 in the form of a sheet parallel to the first direction X and a second hook 312 in the form of a sheet parallel to the second direction Y. The socket 233 includes a first socket 2331 in the form of a strip extending along the first direction X and a second socket 2332 in the form of a strip extending along the second direction Y. The first hook 311 and the first socket 2331 are plugged together, and the second hook 312 and the second socket 2332 are plugged together, thereby fully constraining and positioning the third connecting portion 231 in the first direction X and the second direction Y. In addition, after some of the hooks 31 are correspondingly plugged into the socket 231, the hooks 31 can also be bent so that the positioning plate 3 forms a limit with the third connecting portion 231 in the third direction X.
[0053] Among them, Figure 5 and Figure 7 As shown, in the second direction Y, the end surface of the third side plate 23 is provided with a third groove 232, and the third connecting portions 231 of two adjacent second purlins 2 are pressed toward the first purlin 1 by the positioning plate 3. The positioning plate 3 is fixed to the first purlin 1 via a third bolt 32, and the third grooves 232 of two adjacent second purlins 2 enclose the third bolt 32. This ensures the tight fit between the positioning plate 3 and the third connecting portion 231, thereby ensuring the limiting capability of the third connecting portion 231.
[0054] Among them, Figure 8 and Figure 9As shown, the hooks 31 on the positioning plate 3 can be arranged sequentially around the third bolt 32. In the second direction Y, the second insertion hole 2332 is located on the portion of the third connecting portion 23 that covers the second side plate 12, while the first insertion hole 2331 is located on the portion of the third connecting portion 23 that is offset from the second side plate 12. Accordingly, the first hook 311 extends further after entering the first insertion hole 2331 along the third direction Z to ensure positioning, while the second hook 312 does not extend further after entering the second insertion hole 2332 along the third direction Z to avoid impacting the second side plate 12. Alternatively, the hooks 31 can be formed by flipping the edge of the positioning plate 3.
[0055] During assembly, the first purlin 1 is fixed to the main shaft 6 by the U-bolt fastening group 5, the second purlin 2 is pre-installed on the first purlin 1, and then the photovoltaic module 4 is pre-installed on the second purlin 2. The order of pre-installing the photovoltaic module 4 and the second purlin 2 is not fixed, and the pre-installation order can also be swapped, but the position order from top to bottom is photovoltaic module 4, I-shaped reinforced purlin, and J-shaped purlin. Among them, in use, the first connecting part 211, the first side plate 11, the third side plate 13, the third connecting part 231, and the positioning plate 3 are placed from top to bottom. The first connecting part 211 has an upper mounting hole and is bolted to the first side plate 11 and the first frame 41 of the photovoltaic module 4; after the positioning plate 3 is connected to the third connecting part 231, the positioning plate 3 and the second side plate 12 clamp the third connecting part 231, and the positioning plate 3, the third connecting part 231, and the second side plate 12 are bolted.
[0056] The support structure in this embodiment is equipped with an I-shaped second purlin 2 for reinforcement on the first purlin 1 of the I-shaped structure, changing the long side overlapping support to the long side vertical support, thereby increasing the support structure's ability to support the front load of the photovoltaic module 4 and solving the problem of low load bearing capacity of the photovoltaic module when the tracking bracket of the photovoltaic module is installed.
[0057] In addition to the above-mentioned photovoltaic component support structure, the present invention also provides a photovoltaic system, which includes a plurality of photovoltaic components 4 arranged in sequence along the second direction Y, and also includes a tracking bracket, the tracking bracket includes a photovoltaic component support structure, and the photovoltaic component support structure can specifically be the photovoltaic component support structure provided in any of the above embodiments. The beneficial effects can be referred to the above embodiments accordingly.
[0058] Among them, Figure 6 As shown, the photovoltaic assembly support structure is provided on the back of the photovoltaic assembly 4 , and the first purlin 1 is fixed to the back of the first frame 41 extending along the first direction X on the photovoltaic assembly 4 .
[0059] In addition, if Figure 1As shown, the tracking bracket also includes a main shaft 6 extending along the second direction Y. The main shaft 6 is secured to the back of the first purlin 1 via U-bolts 51. The U-bolts 51 are arranged sequentially along the second direction Y to form a U-bolt fastening group 5. On the back of the same photovoltaic module 4, the main shaft 6 and the second purlins 2 are arranged sequentially along the first direction X. Specifically, in the first direction X, the main shaft 6 can be mounted in the middle of the first purlin 1, and the second purlins 2 can be mounted at each end of the first purlin 1.
