[0039] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0040] First Embodiment

[0041] Please refer to the reference. Figures 1 to 5 This utility model embodiment provides a photovoltaic power generation system 10 (not shown in the figure) for photovoltaic power generation. The photovoltaic bracket 100 can easily and quickly connect at least two fixed frames 120 to each other, simplifying the installation steps, reducing labor and time costs, and after installation, the structure has high strength, is stable and reliable, and is not easy to loosen.

[0042] It should be noted that the photovoltaic power generation system 10 includes a photovoltaic support 100 and multiple photovoltaic modules 200. The multiple photovoltaic modules 200 are all mounted on the photovoltaic support 100. The photovoltaic modules 200 are used to convert light energy into electrical energy through the photovoltaic effect at the semiconductor interface, thereby realizing the photovoltaic power generation function. The photovoltaic support 100 is used to drive the photovoltaic modules 200 to rotate, so that the amount of solar radiation received by the light-receiving surface of the photovoltaic modules 200 is maximized, thereby increasing the power generation of the photovoltaic modules 200.

[0043] The photovoltaic support 100 includes a connecting strip 110 and at least two fixing frames 120. The connecting strip 110 is connected to the at least two fixing frames 120 and is used to fix the relative position of the at least two fixing frames 120 to prevent relative displacement between them. The fixing frames 120 are used for mounting photovoltaic modules 200, with each photovoltaic module 200 mounted within one fixing frame 120. The fixing frames 120 can limit and fix the photovoltaic modules 200. Specifically, the connecting strip 110 includes a connecting wall 111 and two positioning walls 112. The two positioning walls 112 are arranged parallel and spaced apart, and are positioned opposite each other at both ends of the connecting wall 111. The fixing frame 120 is provided with a slot 121, into which the positioning walls 112 are inserted and detachably connected. In this way, by inserting the positioning wall 112 into the slot 121, the connecting strip 110 and the fixed frame 120 can be quickly assembled, and the connecting strip 110 and the fixed frame 120 can be aligned, which facilitates subsequent detachable connection. This allows for convenient and quick interconnection of at least two fixed frames 120, simplifies the installation process, reduces labor and time costs, and ensures high structural strength, stability, reliability, and resistance to loosening after installation.

[0044] In this embodiment, the connecting wall 111 and the two positioning walls 112 are integrally formed to improve the connection strength.

[0045] The fixing frame 120 includes a mounting portion 122, a first limiting plate 123, and a second limiting plate 124. The first limiting plate 123 and the second limiting plate 124 are arranged in parallel and spaced apart, and are both connected to the mounting portion 122, which is used for mounting the photovoltaic module 200. In this embodiment, the mounting portion 122, the first limiting plate 123, and the second limiting plate 124 are integrally formed to improve the connection strength. Specifically, the first limiting plate 123, the mounting part 122, and the second limiting plate 124 together form the slot 121. The positioning wall 112 is disposed between the first limiting plate 123 and the second limiting plate 124 and abuts against the mounting part 122. The mounting part 122 is used to limit the extreme position of the insertion of the positioning wall 112. The first limiting plate 123 and the second limiting plate 124 are both used to fit tightly with the positioning wall 112 so that they can reinforce each other when subjected to external forces (mainly environmental wind force), making the photovoltaic bracket 100 more stable, with a larger safety margin, safe and reliable, and not easy to loosen.

[0046] Furthermore, the first limiting plate 123 has a first through hole 125, and the second limiting plate 124 has a second through hole 126. Both the first through hole 125 and the second through hole 126 communicate with the slot 121. The positioning wall 112 has a positioning hole 113. The positions of the first through hole 125, the second through hole 126 and the positioning hole 113 are corresponding. The first through hole 125, the positioning hole 113 and the second through hole 126 are used for the connector 130 to pass through simultaneously to fix the relative positions of the first limiting plate 123, the positioning wall 112 and the second limiting plate 124, thereby realizing the detachable connection between the positioning wall 112 and the fixing frame 120 and preventing the positioning wall 112 from coming out of the slot 121.

[0047] In this embodiment, the connector 130 includes a first bolt 131 and a first nut 132. During the connection process between the positioning wall 112 and the fixing frame 120, the first bolt 131 is passed sequentially through the first through hole 125, the positioning hole 113, and the second through hole 126, and tightened relative to the first nut 132 to fix the relative positions of the first limiting plate 123, the positioning wall 112, and the second limiting plate 124, thereby fixing the relative positions of the connecting strip 110 and the fixing frame 120. During the disassembly process between the positioning wall 112 and the fixing frame 120, the first bolt 131 is loosened relative to the first nut 132, the first nut 132 is removed, and the first bolt 131 is retracted from the first through hole 125, the positioning hole 113, and the second through hole 126 to release the fixation of the relative positions of the connecting strip 110 and the fixing frame 120, making it easier to detach the connecting strip 110 from the fixing frame 120. However, it is not limited to this. In other embodiments, the connector 130 can be a riveted structure or a tenon joint structure, and the connection method of the connector 130 is not specifically limited.

[0048] It should be noted that there are multiple first through holes 125, multiple second through holes 126, and multiple positioning holes 113. There are also multiple connectors 130. Multiple positioning holes 113 are spaced apart. Each positioning hole 113 and a corresponding first through hole 125 and a second through hole 126 are used for a connector 130 to pass through. Multiple connectors 130 work together to fix the relative position of the connecting strip 110 and the fixing frame 120 at the same time, further improving the connection strength between the connecting strip 110 and the fixing frame 120 and preventing the connecting strip 110 from becoming loose relative to the fixing frame 120.

[0049] Furthermore, a first folded edge 1231 is provided at the free end of the first limiting plate 123 in a direction away from the second limiting plate 124. The first folded edge 1231 is used to improve the rigidity of the first limiting plate 123 and prevent the first limiting plate 123 from deforming or bending under external force. In this embodiment, the folding angle of the first folded edge 1231 is 90 degrees, that is, the first folded edge 1231 is set perpendicular to the first limiting plate 123, so as to further improve the rigidity of the first limiting plate 123.

[0050] The mounting section 122 includes a support section 1221, an extension section 1222, and a retaining section 1223 connected in sequence. The support section 1221 and the retaining section 1223 are arranged in parallel at intervals and are positioned opposite each other at both ends of the extension section 1222. The first limiting plate 123 and the second limiting plate 124 are both connected to the support section 1221. The first limiting plate 123, the support section 1221, and the second limiting plate 124 together form a slot 121, and the positioning wall 112 abuts against the support section 1221. Specifically, the support section 1221, the extension section 1222, and the abutment section 1223 together form a slot 1224. The slot 1224 is used to engage with the photovoltaic module 200. The photovoltaic module 200 extends into the slot 1224 and abuts against the extension section 1222. The extension section 1222 is used to limit the extreme position of the photovoltaic module 200's extension. Both the support section 1221 and the abutment section 1223 are used to fit tightly against the photovoltaic module 200 to securely engage the photovoltaic module 200 within the slot 1224. The support section 1221 is located below the photovoltaic module 200, and the abutment section 1223 is located above the photovoltaic module 200. The support section 1221 is used to support the photovoltaic module 200, and the abutment section 1223 is used to press the photovoltaic module 200 against the support section 1221 to ensure the engagement effect.

[0051] In this embodiment, the support section 1221 and the abutment section 1223 are both arranged perpendicular to the extension section 1222, and the first limiting plate 123 and the second limiting plate 124 are both arranged perpendicular to the support section 1221. The extension section 1222 and the second limiting plate 124 are located on the same plane, which facilitates production and processing and can effectively improve the structural strength of the fixing frame 120.

[0052] Please refer to Figure 6 The fixing frame 120 includes two long sides 127 and two short sides 128. One long side 127, one short side 128, another long side 127, and another short side 128 are connected end-to-end, forming a rectangular cavity 129. The rectangular cavity 129 is used to accommodate the photovoltaic module 200. The two long sides 127 and two short sides 128 work together to limit and fix the photovoltaic module 200, preventing it from becoming loose. Specifically, each of the two long sides 127 and two short sides 128 has a slot 1224 on its inner side. All four slots 1224 communicate with the rectangular cavity 129. After the photovoltaic module 200 is installed, it is simultaneously snapped into the four slots 1224. The four slots 1224 work together to simultaneously limit the length and width of the photovoltaic module 200, ensuring a secure connection.

[0053] Furthermore, slots 121 are provided on the long side 127 and / or the short side 128. When only the long side 127 has a slot 121, the positioning wall 112 of the connecting strip 110 is inserted into the slot 121 and detachably connected to the long side 127. In this case, the connecting strip 110 is used to connect the long sides 127 of two adjacent fixed frames 120 to fix the relative positions of the two adjacent fixed frames 120. When only the short side 128 has a slot 121, the positioning wall 112 of the connecting strip 110 is inserted into the slot 121 and detachably connected to the short side 128. In this case, the connecting strip 110 is used to connect the short sides 128 of two adjacent fixed frames 120 to fix the relative positions of the two adjacent fixed frames 120. When both the long side 127 and the short side 128 are provided with slots 121, there are correspondingly two connecting strips 110; the positioning wall 112 of one connecting strip 110 is inserted into the slot 121 of the long side 127 and is detachably connected to the long side 127. This connecting strip 110 is used to connect the long sides 127 of two fixed frames 120 arranged sequentially along the width direction of the fixed frame 120 to fix the relative position of the two adjacent fixed frames 120; the positioning wall 112 of the other connecting strip 110 is inserted into the slot 121 of the short side 128 and is detachably connected to the short side 128. This connecting strip 110 is used to connect the short sides 128 of two fixed frames 120 arranged sequentially along the length direction of the fixed frame 120 to fix the relative position of the two adjacent fixed frames 120.

[0054] It should be noted that at least two fixed frames 120 are arranged in a rectangular array and divided into at least two groups. Each group has at least one fixed frame 120 and at least one connecting strip 110. Adjacent groups of fixed frames 120 are connected by a connecting strip 110 to fix the relative position of at least two fixed frames 120 and to ensure that the flatness of at least two photovoltaic modules 200 installed in at least two fixed frames 120 is high.

[0055] Please continue to refer to Figure 1 In one specific embodiment, the multiple fixed frames 120 are divided into 11 groups, with one fixed frame 120 in each group. The multiple fixed frames 120 are arranged sequentially along their width direction. Only the long side 127 of the fixed frame 120 is provided with a slot 121. One positioning wall 112 of the connecting strip 110 is inserted into the slot 121 of the long side 127 of one fixed frame 120, and the other positioning wall 112 is inserted into the slot 121 of the long side 127 of an adjacent fixed frame 120. At this time, the connecting strip 110 connects the long sides 127 of two adjacent fixed frames 120 to fix the relative position of the two adjacent fixed frames 120.

[0056] Please refer to Figure 7 In another specific embodiment, the multiple fixing frames 120 are divided into 11 groups, with two fixing frames 120 in each group. The two fixing frames 120 in each group are arranged sequentially along their length direction, and the multiple groups of fixing frames 120 are arranged sequentially along their width direction. The fixing frames 120 are provided with slots 121 only on their long side 127. One positioning wall 112 of the connecting strip 110 is inserted into the slot 121 on the long side 127 of the two fixing frames 120 in each group, and the other positioning wall 112 is inserted into the slot 121 on the long side 127 of the two fixing frames 120 in the adjacent group. At this time, the connecting strip 110 connects the long sides 127 of the two adjacent groups of fixing frames 120 to fix the relative positions of the two adjacent groups of fixing frames 120.

[0057] Please refer to Figure 8 In another specific embodiment, the multiple fixing frames 120 are divided into three groups, with seven fixing frames 120 in each group. The seven fixing frames 120 in each group are arranged sequentially along their length direction, and the multiple groups of fixing frames 120 are arranged sequentially along their width direction. Only the long side 127 of the fixing frame 120 is provided with a slot 121. One positioning wall 112 of the connecting strip 110 is inserted into the slot 121 of the long side 127 of each group of seven fixing frames 120, and the other positioning wall 112 is inserted into the slot 121 of the long side 127 of the adjacent group of seven fixing frames 120. At this time, the connecting strip 110 connects the long sides 127 of the two adjacent groups of fixing frames 120 to fix the relative positions of the two adjacent groups of fixing frames 120.

[0058] Preferably, the photovoltaic support 100 further includes a base 140 and a rotating frame 150. The base 140 is mounted on the foundation, and the rotating frame 150 is rotatably connected to the top of the base 140. The rotating frame 150 can rotate relative to the base 140 about a rotation center, and the base 140 can support and limit the rotation frame 150. Specifically, the rotating frame 150 is connected to the connecting strip 110, and the rotating frame 150 is used to drive the connecting strip 110 to rotate, thereby driving the photovoltaic module 200 to rotate through the fixed frame 120, so as to adjust the tilt angle of the photovoltaic module 200 and improve the power generation.

[0059] The photovoltaic bracket 100 provided in this embodiment of the utility model has a connecting strip 110 connected to at least two fixed frames 120. The fixed frames 120 are used for mounting photovoltaic modules 200. The connecting strip 110 includes a connecting wall 111 and two positioning walls 112. The two positioning walls 112 are arranged parallel and spaced apart, and are positioned opposite each other at both ends of the connecting wall 111. The fixed frame 120 is provided with a slot 121, and the positioning walls 112 are inserted into the slot 121 and are detachably connected to the fixed frame 120. Compared with the prior art, the photovoltaic bracket 100 provided by this utility model, due to the use of the connecting wall 111 connecting the two positioning walls 112 and the slot 121 inserted into the positioning walls 112, can conveniently and quickly realize the mutual connection of at least two fixed frames 120, simplify the installation steps, reduce labor and time costs, and after installation, the structure has high strength, is stable and reliable, and is not easy to loosen. This makes the photovoltaic power generation system 10 have good stability and high power generation efficiency.

[0060] Second Embodiment

[0061] Please refer to Figure 9 This utility model embodiment provides a photovoltaic bracket 100. Compared with the first embodiment, the difference in this embodiment lies in the connection method of the connector 130.

[0062] In this embodiment, the positioning holes 113 of the two positioning walls 112 on the connecting strip 110 are positioned correspondingly. Each positioning wall 112 is inserted into the slot 121 of at least one fixing frame 120. The two positioning holes 113 and the two fixing frames 120 with corresponding positions are used for the connecting piece 130 to pass through at the same time. That is, the connecting piece 130 passes through the two positioning holes 113, the two first through holes 125 and the two second through holes 126 at the same time, so as to fix the relative position of the connecting strip 110 and the two adjacent fixing frames 120 simultaneously. This is stable and reliable, and can save material costs.

[0063] Specifically, the connecting strip 110 includes a second bolt 133, a sleeve 134, and a second nut 135. The sleeve 134 is fitted over the second bolt 133, and the second bolt 133 and the second nut 135 are threaded together. During the connection process between the connecting strip 110 and the fixing frame 120, firstly, one positioning wall 112 of the connecting strip 110 is inserted into the slot 121 of one fixing frame 120, and the other positioning wall 112 of the connecting strip 110 is inserted into the slot 121 of an adjacent fixing frame 120, so that the positions of the two positioning holes 113, the two first through holes 125, and the two second through holes 126 correspond. Then, the second bolt 133 is simultaneously passed through the sleeve 134, the two positioning holes 113, the two first through holes 125, and the two second through holes 126, and tightened relative to the second nut 135, so as to simultaneously fix the relative positions of the connecting strip 110 and the two adjacent fixing frames 120. At this time, the sleeve 134 is positioned between the two adjacent fixing frames 120.

[0064] The photovoltaic bracket 100 provided in this embodiment has the same beneficial effects as the first embodiment, and will not be repeated here.

[0065] Third Embodiment

[0066] Please refer to Figure 10 This utility model embodiment provides a photovoltaic bracket 100. Compared with the second embodiment, the difference in this embodiment lies in the different structure of the connector 130.

[0067] In this embodiment, the connector 130 includes a threaded sleeve 136, a third bolt 137, and a fourth bolt 138. The third bolt 137 and the fourth bolt 138 are disposed opposite to each other at both ends of the threaded sleeve 136, and both are threadedly engaged with the threaded sleeve 136. During the connection process between the connecting strip 110 and the fixed frame 120, firstly, one positioning wall 112 of the connecting strip 110 is inserted into the slot 121 of one fixed frame 120, and the other positioning wall 112 of the connecting strip 110 is inserted into the slot 121 of an adjacent fixed frame 120, so that the positions of the two positioning holes 113, the two first through holes 125 and the two second through holes 126 correspond. Then, the threaded sleeve 136 is placed between the two adjacent fixed frames 120, and the third bolt 137 is passed through one first through hole 125, one positioning hole 113 and one second through hole 126 in sequence and tightened relative to the threaded sleeve 136. Then, the fourth bolt 138 is passed through another first through hole 125, another positioning hole 113 and another second through hole 126 in sequence and tightened relative to the threaded sleeve 136, so as to simultaneously fix the relative positions of the connecting strip 110 and the two adjacent fixed frames 120.

[0068] The beneficial effects of the photovoltaic bracket 100 provided in this embodiment are the same as those in the second embodiment, and will not be repeated here.

[0069] Fourth embodiment

[0070] Please refer to Figure 11 This utility model embodiment provides a photovoltaic bracket 100. Compared with the first embodiment, the difference in this embodiment is that the second limiting plate 124 is provided with a second folded edge 1241.

[0071] In this embodiment, the free end of the second limiting plate 124 is provided with a second folded edge 1241 in a direction away from the first limiting plate 123. The second folded edge 1241 is used to improve the rigidity of the second limiting plate 124 and prevent the second limiting plate 124 from deforming or bending under external force. Specifically, the folding angle of the second folded edge 1241 is 90 degrees, that is, the second folded edge 1241 is set perpendicular to the second limiting plate 124 to further improve the rigidity of the second limiting plate 124.

[0072] The beneficial effects of the photovoltaic bracket 100 provided in this embodiment are the same as those in the first embodiment, and will not be repeated here.

[0073] Fifth Embodiment

[0074] Please refer to Figure 12 This utility model embodiment provides a photovoltaic bracket 100. Compared with the first embodiment, the difference in this embodiment is that the extension section 1222 and the second limiting plate 124 are no longer located on the same plane.

[0075] In this embodiment, the second limiting plate 124 is disposed between the plane containing the first limiting plate 123 and the extension section 1222. This allows for a reduction in the spacing between adjacent photovoltaic modules 200 while maintaining the width of the connecting wall 111 in the connecting strip 110, thereby increasing the installation density of the photovoltaic modules 200 and thus increasing power generation. Alternatively, it allows for an increase in the width of the connecting wall 111 in the connecting strip 110 while maintaining the spacing between adjacent photovoltaic modules 200, thereby improving the structural strength of the connecting strip 110, preventing deformation or bending, and ensuring stability and reliability.

[0076] The beneficial effects of the photovoltaic bracket 100 provided in this embodiment are the same as those in the first embodiment, and will not be repeated here.
