[0048] Large-scale photovoltaic modules 1 are usually installed outdoors in harsh environments far away from residential areas. They have high requirements for the strength and life of photovoltaic brackets. Therefore, steel parts are usually used, which have low aesthetics. On-site assembly usually requires welding and a large number of fasteners 300, making assembly and disassembly inconvenient.

[0049] At present, photovoltaic modules 1 are promoted for home use. For rooftop photovoltaic modules 1, the requirements for aesthetics are low, and due to the high installation environment, they are usually installed by professionals; but for photovoltaic fences, on the one hand, the requirements for aesthetics are high, and on the other hand, consumers prefer to be able to install them by themselves, and have high requirements for the convenience of disassembly and assembly.

[0050] Therefore, the embodiment of the present application provides a vertical photovoltaic bracket, which forms a column assembly 100 and a beam assembly 200 through plug-in assembly, thereby improving the convenience of assembly and disassembly, and by adopting aluminum profiles, improving the aesthetics, reducing the weight, and further improving the convenience of assembly and disassembly.

[0052] The vertical photovoltaic support includes a plurality of column assemblies 100 and a plurality of beam assemblies 200 . At least two beam assemblies 200 are arranged between two adjacent column members along the height direction, thereby forming a main area for installing the photovoltaic assembly 1 .

[0053] The column assembly 100 includes a column body 110 and a column cover 120 inserted in front of the column body 110 along the height direction of the column body 110. The beam assembly 200 includes a beam body 210 and a beam limiter 220 inserted at the end of the beam body 210 along the length direction of the beam body 210. That is, the convenience of plug-in assembly and high repeatability are utilized to improve the convenience of assembly and disassembly of the column assembly 100 and the beam assembly 200.

[0054] Both the column body 110 and the column cover 120 include an outer wall 101 and a molded portion 102 located on one side of the outer wall 101. The surface of the outer wall 101 facing away from the molded portion 102 is smooth, and the molded portion 102 includes a plug-in structure. When the column body 110 and column cover 120 are plugged together as a whole, a storage space is formed on their sides. The end of the crossbeam body 210 extends into the storage space and is removably connected to the column body 110 within the storage space via a crossbeam stop 220 and fasteners 300.

[0055] Furthermore, the column body 110 , the column cover plate 120 , the beam body 210 and the beam stopper 220 are all made of aluminum profiles, that is, aluminum is used as the main component and different cross-sectional shapes are obtained through hot melting and extrusion.

[0056] In this manner, the outer walls of the column body 110 and the column cover plate 120 are both smooth, and the connection between the beam body 210 and the column body 110 is hidden in the accommodating space, thereby improving the overall regularity of the bracket and making it more beautiful.

[0057] At the same time, by using aluminum profiles to prepare the main components of the bracket, namely the column body 110, the column cover 120, the beam body 210 and the beam limiter 220, it has high aesthetics and light weight, which can further facilitate disassembly and assembly; and it is convenient for the molding of each component, which can effectively control the manufacturing cost; moreover, through cross-section design, the strength of each component can be ensured, thereby ensuring the strength of the bracket.

[0058] In one embodiment, the crossbeam body 210 is provided with grooves 211 along its length for clamping the photovoltaic assembly 1 , thereby facilitating assembly and disassembly of the photovoltaic assembly 1 .

[0059] It is understandable that when the photovoltaic components 1 are installed on the upper and lower sides of the beam body 210 , grooves 211 are provided on the upper and lower sides of the beam body 210 .

Furthermore, when the column body 110, column cover 120, and side sealing plates 130 are assembled as a whole, their outer surface is smooth, thereby enhancing the regularity of the column assembly 100 at the edge of the bracket and enhancing its aesthetics.

[0062] In one embodiment, the vertical photovoltaic support further includes a top cover 150, which is snap-fitted or plugged into the top of the column assembly 100 to protect the interior of the column assembly 100, thereby improving the aesthetics of the column assembly 100 and facilitating assembly and disassembly.

The base 140 can be made of steel, facilitating the welding of the plug-in portion 141 and the base plate 142, thereby providing increased strength. The base 140 can also be further reinforced to the ground via the base plate 142, thereby enhancing the stability of the support.

[0065] In one embodiment, the forming portion 102 of the column body 110 includes a hollow structure 111 located in the middle, the front side of the hollow structure 111 is provided with a first structure 103 in the plug-in structure, the left and right sides of the hollow structure 111 are symmetrically provided with a first connecting structure 112, and the front side of the hollow structure 111 is also provided with a second connecting structure 113, and the first connecting structure 112 and the second connecting structure 113 are both located in the accommodating space.

[0067] The second connection structure 113 and the beam stopper 220 are detachably connected via fasteners 300 , such as screws.

[0068] At the same time, the hollow structure 111 , the first connection structure 112 , the first structure 103 , etc. make the cross-section of the forming portion 102 of the column body 110 more complex, thereby enhancing the strength of the column body 110 .

[0069] Preferably, the hollow structure 111 is a square tubular structure, so as to further improve the strength of the column body 110 .

[0070] In one embodiment, the cross-section of the first structure 103 in the plug-in structure along the height direction includes an elliptical protrusion, and adaptingly, the cross-section of the second structure 104 along the height direction that is plugged in with the first structure 103 includes a semi-enclosed groove portion. The combination of the two makes the assembly stability of the column body 110 and the column cover plate 120 higher and the service life longer.

[0071] In one embodiment, the first connecting structure 112 includes a sliding groove located in the middle and limiting portions located on both sides of the sliding groove.

[0072] In one embodiment, the second connection structure 113 includes a connection surface, and the beam stopper 220 includes a connection portion 222 . The connection portion 222 fixes the beam stopper 220 and the column body 110 by screws penetrating the connection surface.
