Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] At present, during the installation process of photovoltaic power generation components, adjacent metal plates are usually fixed and spliced ​​by penetrating the metal plates and nailing them. However, this nailing method will leave a large number of nail holes on the metal plates, causing structural damage to the metal plates, making it inconvenient to reinstall and use the metal plates.

[0030] Embodiment 1

[0031] Please refer to Figures 1 to 9 In a possible implementation, the photovoltaic power generation component of the embodiment of the utility model includes a roof base 10 and a plurality of metal plates 30, and a support 20 is arranged between adjacent metal plates 30. The photovoltaic power generation component can be arranged on the roof of a factory building, a carport, a warehouse or a house. The support 20 and the metal plate 30 are both arranged on the roof base 10; the two sides of the support 20 are respectively connected to a metal plate 30, and the support 20 includes a first folding portion 21 and a second folding portion 22 folded in opposite directions; the metal plate 30 includes a third folding portion 31 respectively arranged on both sides of the metal plate 30; the first folding portion 21 and the second folding portion 22 of the support 20 are respectively connected to the third folding portion 31 of the adjacent metal plate 30. Among them, the structures of the first folding portion 21 and the second folding portion 22 are the same, and only the bending directions are different.

[0032] Specifically, the roof base 10 is a base support structure of a photovoltaic power generation assembly, the support 20 and the metal plate 30 are arranged on the roof base 10, and the roof base 10 can be a roof structure such as a purlin, a tile strip or a keel frame.

[0033] In the present utility model, if Figures 2 to 5 As shown. The adjacent metal plates 30 arranged on the roof base 10 are connected through the support 20, and the connection method is specifically through the method of folding and bending. The support 20 includes a first folding portion 21 and a second folding portion 22, and the metal plate 30 includes a third folding portion 31 arranged on both sides thereof. The first folding portion 21, the second folding portion 22 of the support 20 and the third folding portions 31 on both sides of the metal plate 30 are all bendable. When the assembly connection is specifically performed, a metal plate 30 is respectively arranged on both sides of the support 20, and the first folding portion 21 and the second folding portion 22 are respectively arranged on one of the third folding portions 31 of the metal plate 30. By bending the first folding portion 21 and the second folding portion 22, the first folding portion 21 and the second folding portion 22 can be bent and joined upright with the third folding portion 31, so as to realize the assembly connection of two adjacent metal plates 30 through the support 20.

[0034] Therefore, the assembly and connection of adjacent metal plates 30 is completed by bending the support 20 and the metal plate 30, and there is no need to perforate the metal plate 30 or perform other destructive operations during assembly, thereby maintaining the structural integrity of the metal plate 30, so that the metal plate 30 can continue to be installed and used again; and during installation and disassembly, the support 20 and the metal plate 30 can be installed and disassembled without loss, so as to facilitate the reuse of the support 20 and the metal plate 30, thereby saving material costs and resources; in addition, the upright snap-fit ​​assembly of adjacent metal plates 30 achieved by bending is simple to install and can be applied to most household roofs.

[0035] Furthermore, because the two adjacent metal plates 30 are respectively arranged on both sides of the support 20, the bending directions of the first folding portion 21 and the second folding portion 22 used to bend and connect the metal plates 30 are that the first folding portion 21 and the second folding portion 22 are bent in opposite directions respectively, that is, the first folding portion 21 of the support 20 is bent toward the metal plate 30 arranged on one side of the support 20, and the second folding portion 22 of the support 20 is bent toward the metal plate 30 arranged on the other side of the support 20.

[0036] Furthermore, if Figure 3 As shown, the first folding portion 21 and the second folding portion 22 of the support 20 are specifically staggered, and the corresponding metal plates 30 arranged on both sides of the support 20 are also staggered. Such a staggered folding portion design enhances the connection stability between the support 20 and the metal plate 30, making the assembled structure more stable and reducing the risk of loosening of the plate due to wind pressure or other external forces; and the staggered folding portion setting increases the overlapping portion of the support 20 and the metal plate 30, providing multiple protections, thereby achieving the effect of improving the waterproof performance. Of course, in other embodiments, the first folding portion 21 and the second folding portion 22 of the support 20 can also be flush, that is, not staggered.

[0037] In addition, in order to facilitate bending of the support 20, the support 20 is specifically a flexible support 20. When the support 20 is specifically assembled and connected to the metal plate 30, the support 20 is as follows: Figure 5 The figure shows a closed state, so that two adjacent metal plates 30 are snap-fitted and assembled; when the metal plates 30 need to be disassembled, the support 20 is as shown in FIG. Figure 4 The specifically unfolded state is used to facilitate installation and removal of the support 20 and the metal plate 30 .

[0040] Specifically, the photovoltaic laminate 40 is arranged on the metal plate 30, and, for the convenience of manufacturing and fixing, a first adhesive film 70 is arranged between the metal plate 30 and the photovoltaic laminate 40. The metal plate 30 and the photovoltaic laminate 40 are laminated and compounded into a whole by the first adhesive film 70, so as to facilitate the installation of the photovoltaic laminate 40.

[0041] Furthermore, if Figure 7 As shown, in a possible embodiment, the photovoltaic laminate 40 specifically includes a photovoltaic glass 41, a cell 42 and a photovoltaic backplane 43 which are stacked in sequence, and a second adhesive film 44 is arranged between the photovoltaic glass 41 and the cell 42 to facilitate the lamination between the photovoltaic glass 41 and the cell 42; a third adhesive film 45 is arranged between the cell 42 and the photovoltaic backplane 43 to facilitate the lamination between the cell 42 and the photovoltaic backplane 43.

[0044] In order to strengthen the bending connection between the support 20 and the metal plate 30, the present invention further provides a buckle cover 50 on the support 20, and the buckle cover 50 has bending parts 51 on both sides. When the buckle cover 50 is installed, the bending parts 51 of the buckle cover 50 buckle the first folding part 21 and the second folding part 22 of the support 20 inward to strengthen the bending connection between the support 20 and the metal plate 30. In addition, the buckle cover 50 can also play a waterproof role to prevent moisture from entering from the joint of the support 20 and the metal plate 30.

[0045] Moreover, further, in a possible implementation, a sealant 80 is provided between the buckle cover 50 and the support 20. Specifically, the sealant 80 is provided at the buckle joint of the buckle cover 50 and the support 20 in the vertical direction, so that the buckle cover 50 can be buckled on the support 20 without external nailing of the buckle cover 50, thereby achieving the effect of fixing the buckle cover 50; and the setting of the sealant 80 can also play a sealing role to prevent water vapor from entering, thereby further achieving a waterproof effect.

[0046] In addition, in a possible implementation manner, Figure 6 and Figure 8As shown, a waveform is provided on the bending portion 51 , and a waveform is provided on the third folding portion 31 ; the waveform on the bending portion 51 corresponds to the waveform on the third folding portion 31 .

[0047] Specifically, the bending portion 51 and the third folding portion 31 are both provided with waveforms. And because the waveforms on the bending portion 51 and the third folding portion 31 are provided correspondingly, the buckle cover 50 can be buckled and connected to the support 20 without nailing on the buckle cover 50.

[0048] Furthermore, by setting the wave shape of the bent portion 51 of the outermost buckle cover 50, capillary water can be prevented from entering the photovoltaic power generation component from the buckle cover 50, so as to further achieve a waterproof effect.
