[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0027] At present, during the installation process of integrated photovoltaic power generation household metal plates (metal tiles), it is usually necessary to penetrate the metal plates and nail them to fix and splice the adjacent metal plates. However, this splicing method using nails will leave a large number of nail holes on the metal plates, which will not only affect the secondary use of the metal plates, but also significantly reduce the waterproof performance of the metal plate roof. Because the presence of nail holes on the metal plates will make the user's roof more prone to leakage, thereby affecting the durability and functionality of the overall photovoltaic power generation components.

[0028] Therefore, in order to solve the above technical problems, the utility model provides a photovoltaic power generation component and a photovoltaic power generation system. The photovoltaic power generation component of the embodiment of the utility model is provided with a support, and the adjacent metal plates can be fixed and spliced ​​through the support, which is convenient for construction and installation, and there is no need to nail on the metal plate, thereby achieving the effect of improving the waterproofness and reliability of the photovoltaic power generation component and the photovoltaic power generation system.

[0029] Embodiment 1

[0030] Please refer to Figures 1 to 8 In a possible implementation, the photovoltaic power generation component of the embodiment of the utility model includes: a plurality of metal plates 20, and a support 10 is arranged between adjacent metal plates 20. The photovoltaic power generation component can be set on the roof of a factory building, a carport, a warehouse or a house. The two sides of the support 10 are respectively connected to a metal plate 20, and one or more supports 10 for connecting the metal plates 20 are arranged between two adjacent metal plates 20. The support 10 includes a first bending waveform portion 11 respectively arranged on both sides of the support 10, and the metal plate 20 includes a second bending waveform portion 21 respectively arranged on both sides of the metal plate 20; the waveform of the first bending waveform portion 11 is arranged corresponding to the waveform of the second bending waveform portion 21; wherein, the two first bending waveform portions 11 of the support 10 are respectively buckled and connected with a second bending waveform portion 21 of the adjacent metal plate 20.

[0031] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in order to solve the problem that the nailing splicing method used in the prior art will leave a large number of nail holes on the metal plate 20. In the embodiment of the utility model, a support 10 is provided to splice adjacent metal plates 20. A plurality of supports 10 for connecting the metal plates 20 are provided between two adjacent metal plates 20, and a metal plate 20 is connected to both sides of a support 10. The support 10 has a first bending corrugated portion 11 provided on both sides of the support 10, that is, the first bending corrugated portion 11 is provided on both sides of the support 10, and the metal plate 20 has a second bending corrugated portion 21 provided on both sides of the metal plate 20, that is, the second bending corrugated portion 21 is provided on both sides of the metal plate 20.

[0032] Furthermore, the waveform on the first bending waveform portion 11 and the waveform on the second bending waveform portion 21 are set correspondingly. Therefore, when the support 10 is actually connected to the adjacent metal plate 20, the two first bending waveform portions 11 of one support 10 are respectively buckled and connected with one second bending waveform portion 21 of the adjacent metal plate 20 of the support 10. The support can assemble and connect the adjacent metal plates 20 through the first bending waveform portion 11 and the second bending waveform portion. Among them, the waveform on the first bending waveform portion 11 is specifically an ear plate wave.

[0033] When the support 10 and the metal plate 20 are specifically connected, the first bent waveform portion 11 of the support 10 is arranged on the outside of the second bent waveform portion 21 of the metal plate 20, and the first bent waveform portions 11 on both sides of the support 10 are inwardly buckled to the second bent waveform portions 21 of the metal plate 20, so that the support 10 can be connected to the metal plates 20 on both sides thereof to complete the assembly connection between adjacent metal plates 20.

[0034] Therefore, in the embodiment of the utility model, by setting the support 10, the adjacent metal plates 20 can be fixedly spliced ​​and connected through the support 10, which is convenient for construction and installation, and there is no need to nail the metal plates 20, thereby achieving the effect of improving the waterproofness and reliability of the photovoltaic power generation components.

[0035] In addition, the support 10 is specifically a support 10 made of metal material, preferably a steel support 10. By setting the support 10 to be a support 10 made of high-strength steel, the support 10 can be made less likely to deform, thereby achieving the effect of ensuring the long-term stability and reliability of the support 10.

[0036] When setting up the photovoltaic power generation components, first place multiple adjacent metal plates 20, leaving a certain gap between the adjacent metal plates 20 (equal to the width of the bottom of the support 10), and place multiple supports 10 in the gap between the adjacent metal plates 20, and press the supports 10 from top to top against the waveform of the second bent waveform 21 of the metal plate 20, so that the waveform of the first bent waveform 11 on both sides of the support 10 just buckles the waveform of the second bent waveform 21 of the two metal plates 20, and then fix the support 10 to complete the splicing connection of the metal plates 20.

[0037] Embodiment 2

[0038] Based on Example 1, in a possible implementation manner, as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the photovoltaic assembly further includes a photovoltaic power generation module 30 disposed on the metal plate 20 , and the metal plate 20 and the photovoltaic power generation module 30 are laminated and integrated.

[0039] Specifically, the photovoltaic power generation module 30 is arranged on the metal plate 20, and, in order to facilitate manufacturing and fixing, the photovoltaic power generation module 30 and the metal plate 20 are directly laminated and composited into one; the photovoltaic power generation module 30 and the metal plate 20 are laminated and composited into one, which can also enhance the structural strength of the photovoltaic component, simplify the installation process, and enhance the stability and durability of the photovoltaic component.

[0040] Embodiment 3

[0041] Based on Example 1, in a possible implementation manner, as Figure 1 , Figure 7 and Figure 8 As shown, the photovoltaic assembly further includes a buckle cover plate 40 disposed on the support 10 , and the buckle cover plate 40 includes bending portions 41 disposed on both sides of the buckle cover plate 40 , and the bending portions 41 are used to buckle the first bent waveform portion 11 .

[0042] Specifically, in order to strengthen the connection between the support 10 and the metal plate 20, a buckle cover plate 40 is provided in the photovoltaic module. The buckle cover plate 40 is specifically a U-shaped structure. When installed, the buckle cover plate 40 is provided on the metal plate 20 and the support 10 to cover the metal plate 20 and the support 10. In addition, bending portions 41 are provided on both sides of the buckle cover plate 40. Through the provision of the bending portions 41, the first bent corrugated portion 11 can be buckled inwardly to strengthen the buckled connection between the second bent corrugated portion 21 and the first bent corrugated portion 11, thereby achieving the effect of strengthening the connection between the support 10 and the metal plate 20.

[0043] Moreover, for the setting of the snap cover plate 40, the snap cover plate 40 can be set to correspond to the number of the supports 10, and one snap cover plate 40 is set corresponding to one support 10 for snap cover connection; of course, it can also be designed that one snap cover plate 40 snaps on multiple supports 10 for snap cover connection, and the user can choose according to actual conditions. The specific length of the snap cover plate 40 can be determined according to the actual usage scenario and the plate processing conditions.

[0044] Further, in a possible implementation manner, as Figure 1 , Figure 7 and Figure 8 As shown, a limiting waveform is provided on the edge of the bent portion 41 .

[0045] Specifically, the bending portions 41 on both sides of the buckle cover plate 40 are provided with limiting waveforms, and the waveform of the limiting waveform specifically corresponds to the waveform of the first bending waveform portion 11 of the support 10. Through the design of such limiting waveforms, when the buckle cover plate 40 buckles the support 10, it can be fastened on the support 10, which can effectively prevent the buckle cover plate 40 from falling off or sliding out of the support 10, thereby achieving the effect of improving the stability and safety of the installation of the buckle cover plate 40.

[0046] Furthermore, in order to strengthen the connection between the buckle cover plate 40 and the support 10, the edge of the first bent corrugated portion 11 of the support 10 is specifically abutted against the inner wall of the bent portion 41 of the buckle cover plate 40, thereby improving the tightness between the buckle cover plate 40 and the support 10, and further preventing the buckle cover plate 40 from falling off or sliding out of the support 10, thereby achieving the effect of improving the stability and safety of the installation of the buckle cover plate 40.

[0047] Embodiment 4

[0048] Based on Example 3, in a possible implementation manner, please continue to refer to Figures 1 to 8 A cable 60 is arranged on the support 10 , and the cover plate 40 covers and wraps the cable 60 . Moreover, the cable 60 is connected to the metal plate 20 in one piece.

[0049] Specifically, the photovoltaic module also includes a cable 60. In the prior art, the cable 60 is usually arranged on the back of the metal plate 20, so it is more troublesome and laborious to connect and install. However, in the present invention, the adjacent metal plates 20 are assembled by the support 10, that is, the support 10 gap is left between the adjacent metal plates 20 to serve as the arrangement channel of the cable 60 and the terminal block, so when installing the metal plate 20 and connecting the cable 60, the user can connect the cable 60 on the front of the metal plate 20, thereby achieving the effect of improving the convenience of connecting the cable 60.

[0050] Moreover, in the utility model, the cable 60 is arranged in the buckle cover plate 40, and the buckle cover plate 40 covers and wraps the cable 60 to prevent the cable 60 from being eroded by rain and damaged by the external environment. At the same time, when the cable 60 needs to be later enclosed and repaired, it is only necessary to open the buckle cover plate 40 to carry out the operation, and the buckle cover plate 40 can be installed after the inspection is completed, thereby achieving the effect of facilitating the maintenance of the cable 60.

[0051] Embodiment 5

[0052] Based on Example 1, in a possible implementation manner, as Figures 1 to 3 As shown, the support 10 further includes a support portion 12 disposed between the first bending wave-shaped portions 11 , and at least one hole 13 is disposed on the support portion 12 .

[0053] Specifically, the support 10 further includes a support portion 12, which is a portion disposed between the first bent wave portions 11 on both sides of the support 10. The support portion 12 is provided with at least one hole 13, and at least one screw 50 is disposed on the support portion 12, and the screw 50 is disposed corresponding to the hole 13.

[0054] That is, because the photovoltaic power generation assembly is specifically set on the roof, the support 10 also needs to be fixed on the roof. Therefore, the utility model punches holes 13 on the support 10 by nailing, and then drives screws 50 into the nail holes to fix the support 10 on the purlin or keel frame of the roof.

[0056] See also Figures 1 to 8The photovoltaic power generation system of the embodiment of the utility model includes a purlin or keel frame and a photovoltaic power generation component as described in any one of Embodiments 1 to 6 arranged on the purlin or keel frame.
