[0040] First embodiment

[0041] Please refer to Figures 1 to 5 The embodiment of the present invention provides a photovoltaic power generation system 10 (not shown) for photovoltaic power generation. The photovoltaic bracket 100 can conveniently and quickly realize the mutual connection of at least two fixing frames 120, simplify the installation steps, reduce the labor cost and time cost, and after the installation is completed, the structure is high in strength, stable and reliable, and not easy to loosen.

The photovoltaic support 100 is used to drive the photovoltaic modules 200 to rotate so that the light-receiving surface of the photovoltaic modules 200 receives the maximum amount of sunlight radiation, thereby increasing the power generation of the photovoltaic modules 200.

[0043] The photovoltaic support 100 includes a connecting bar 110 and at least two fixed frames 120. The connecting bar 110 is connected to the at least two fixed frames 120, and the connecting bar 110 is used to fix the relative positions of the at least two fixed frames 120 to prevent relative displacement between the at least two fixed frames 120. The fixed frame 120 is used for the installation of photovoltaic components 200, and each photovoltaic component 200 is installed in a fixed frame 120, and the fixed frame 120 can limit and fix the photovoltaic components 200. Specifically, the connecting bar 110 includes a connecting wall 111 and two positioning walls 112. The two positioning walls 112 are arranged in parallel and spaced apart, and are relatively arranged at both ends of the connecting wall 111. The fixed frame 120 is provided with a slot 121, and the positioning wall 112 is inserted into the slot 121 and is detachably connected to the fixed frame 120. In this way, by plugging the positioning wall 112 into the slot 121, the connecting strip 110 and the fixing frame 120 can be quickly assembled to achieve alignment between the connecting strip 110 and the fixing frame 120, which is convenient for subsequent detachable connection, thereby conveniently and quickly connecting at least two fixing frames 120 to each other, simplifying the installation steps, reducing labor costs and time costs, and after the installation is completed, the structure has high strength, is stable and reliable, and is not easy to loosen.

[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, and the mounting portion 122 is used for mounting the photovoltaic assembly 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 portion 122 and the second limiting plate 124 together form a slot 121, the positioning wall 112 is arranged between the first limiting plate 123 and the second limiting plate 124, and is abutted against the mounting portion 122, the mounting portion 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 as to have a mutual reinforcement effect when subjected to external force (mainly environmental wind force), so that the photovoltaic bracket 100 has better stability, a larger safety margin, is safe and reliable, and is not easy to loosen.

[0046] Furthermore, the first limiting plate 123 is provided with a first through hole 125, and the second limiting plate 124 is provided with a second through hole 126, and both the first through hole 125 and the second through hole 126 are connected to the slot 121. The positioning wall 112 is provided with a positioning hole 113, and the positions of the first through hole 125, the second through hole 126 and the positioning hole 113 correspond to each other, and the first through hole 125, the positioning hole 113 and the second through hole 126 are used for the connector 130 to pass through at the same time, so as to fix the relative positions of the first limiting plate 123, the positioning wall 112 and the second limiting plate 124, so as to realize the detachable connection between the positioning wall 112 and the fixing frame 120, and prevent the positioning wall 112 from falling out of the slot 121.

[0047] In this embodiment, the connecting member 130 includes a first bolt 131 and a first nut 132. During the connection process between the positioning wall 112 and the fixed frame 120, the first bolt 131 is passed through the first through hole 125, the positioning hole 113, and the second through hole 126 in sequence, and is 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 fixed frame 120. During the disassembly process between the positioning wall 112 and the fixed 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 out of 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 fixed frame 120, so as to facilitate the disassembly of the connecting strip 110 from the fixed frame 120. However, the present invention is not limited thereto. In other embodiments, the connector 130 may be a riveted structure or a mortise and tenon structure, and the connection method of the connector 130 is not specifically limited.

Each positioning hole 113 and a first through hole 125 and a second through hole 126 corresponding to its position are used for allowing a connecting member 130 to pass through. The multiple connecting members 130 work together to simultaneously fix the relative positions of the connecting bar 110 and the fixed frame 120, further improve the connection strength between the connecting bar 110 and the fixed frame 120, and prevent the connecting bar 110 from loosening relative to the fixed 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, and the first folded edge 1231 is used to improve the rigidity of the first limiting plate 123 to prevent the first limiting plate 123 from being deformed or bent under the action of an 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 provided perpendicular to the first limiting plate 123, so as to further improve the rigidity of the first limiting plate 123.

[0050] The mounting portion 122 includes a supporting section 1221, an extending section 1222, and a butting section 1223 connected in sequence. The supporting section 1221 and the butting section 1223 are arranged in parallel and spaced apart, and are arranged at two ends of the extending section 1222 opposite to each other. The first limiting plate 123 and the second limiting plate 124 are both connected to the supporting section 1221. The first limiting plate 123, the supporting section 1221, and the second limiting plate 124 together form a slot 121, and the positioning wall 112 butts against the supporting section 1221. Specifically, the support section 1221, the extension section 1222 and the abutting section 1223 together form a slot 1224, and the slot 1224 is used to be connected with the photovoltaic component 200. The photovoltaic component 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 component 200. The support section 1221 and the abutting section 1223 are both used to fit tightly with the photovoltaic component 200 to firmly connect the photovoltaic component 200 to the slot 1224, wherein the support section 1221 is arranged below the photovoltaic component 200, and the abutting section 1223 is arranged above the photovoltaic component 200. The support section 1221 is used to support the photovoltaic component 200, and the abutting section 1223 is used to press the photovoltaic component 200 on the support section 1221 to ensure the connecting effect.

The rectangular cavity 129 is used to accommodate the photovoltaic module 200. The two long sides 127 and the two short sides 128 work together to limit and fix the photovoltaic module 200 to prevent the photovoltaic module 200 from loosening. Specifically, the inner sides of the two long sides 127 and the two short sides 128 are provided with card slots 1224, and the four card slots 1224 are all connected to the rectangular cavity 129. After the photovoltaic module 200 is installed, the photovoltaic module 200 is simultaneously carded in the four card slots 1224. The four card slots 1224 work together to simultaneously limit the length direction and width direction of the photovoltaic module 200 to ensure the card connection effect.
