Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a photovoltaic component frame installation structure. Background Art

[0002] Photovoltaic modules are part of the solar power generation system. Single solar cells cannot be used directly as a power source. When used as a power source, several single cells must be connected in series and parallel and tightly sealed into modules. Solar cell modules are the core and most important part of the solar power generation system. Photovoltaic panels cannot be used alone, so multiple groups of photovoltaic panels need to be combined to absorb sunlight.

[0003] At present, photovoltaic panels are mainly installed by means of a press block and an edge press block. The middle press block is located between adjacent photovoltaic panels, and the edge press block is located on the outside of the photovoltaic panel on the side to limit the displacement of the photovoltaic panel. For example, the Chinese patent document with the announcement number CN217428034U discloses an adjustable edge press block for photovoltaic module installation, including: a first press block, a second press block and a fastener, a press plate is provided on one side of the first press block, a first clamping portion is provided on the other side of the first press block, and a plurality of second clamping portions at different heights are provided on one side of the second press block. During installation, the second clamping portion at the corresponding height position is selected according to the thickness of the photovoltaic module to be clamped with the first clamping portion, and finally the first press block and the bearing component are fixed by the fastener to press the press plate against the upper surface of the photovoltaic module, and at the same time, the second press block is pressed against the bearing component. Although the pressing block can connect the photovoltaic panels, its pressing plate is pressed tightly against the upper surface of the photovoltaic module and is in direct contact with the photovoltaic module. The pressing block may cause damage to the photovoltaic module. The pressing block may also block the upper surface of the photovoltaic module, causing the light-receiving area of ​​the photovoltaic module to become smaller, thereby affecting the energy conversion efficiency of the photovoltaic module.

[0025] The present invention will be described in detail with reference to the accompanying drawings. What is described here is only a preferred embodiment of the present invention, and those skilled in the art can think of other ways to implement the present invention based on the preferred embodiment, and other ways also fall within the scope of the present invention.

[0026] Example

[0027] Reference Figure 1-Figure 3The present embodiment provides a photovoltaic module frame installation structure, including a frame component 100 and a pressing block 200. A connecting component 110 is arranged on the outer side of the frame component 100. The connecting component 110 is embedded in or extends a snap-in groove 111 on the outer side of the frame component 100. One end of the pressing block 200 is embedded in the snap-in groove 111 and snap-in with the connecting component 110. The installation and connection of the photovoltaic module 300 are completed by snapping the pressing block 200 with the frame component 100, so as to avoid the pressing block 200 directly pressing on the upper surface of the photovoltaic module 300, and will not block the light-receiving area on the surface of the photovoltaic module 300, which is conducive to maintaining the energy conversion efficiency of the photovoltaic module 300. On the other hand, in the actual installation of the photovoltaic module 300 in the power station, due to long-term snow load and wind load and the presence of vibration-generating equipment under the power station, the photovoltaic module 300 and the pressing block 200 are loosened and displaced, which may eventually cause the photovoltaic module 300 to fall off. In the present embodiment, the pressing block 200 is snap-in with the connecting component 110, and the connection is more tightly connected, which can reduce the risk of the photovoltaic module 300 falling off.

[0028] Specifically, Figure 1 and Figure 2 As shown, the frame component 100 includes a bottom plane frame 120, a middle connecting frame 130 and a top supporting frame 140 which are connected in sequence, and the top supporting frame 140 is used to support the photovoltaic module 300; the snap-in groove 111 is located on the outside of the middle connecting frame 130, does not occupy the space of the bottom plane frame 120 and the top supporting frame 140 of the frame component 100, and the structural layout is reasonable.

[0029] Furthermore, in this embodiment, the structure of the clamping slot 111 is divided into an embedded type and an extended type. Figure 1 As shown, the clamping slot 111 is an embedded structure, and the clamping slot 111 is embedded in the outer side of the middle connecting frame 130, and hook structures are provided on both the upper and lower sides of the opening end of the clamping slot 111. Figure 2 As shown, the snap-fit ​​groove 111 is an extensional structure, and the connecting component 110 includes a first groove edge 112 and a second groove edge 113, which extend outward to form the snap-fit ​​groove 111, and one end of the second groove edge 113 extending outward forms a hook structure.

[0030] The hook-shaped structure of the clamping groove 111 can increase the firmness of the clamping of the pressing block 200 and the clamping groove 111, further prevent the pressing block 200 and the frame component 100 from falling off, and increase the stability of the installation of the photovoltaic module 300. Figure 1 and Figure 2As shown, the pressing block 200 includes a clamping end 210, a positioning end 220 and a supporting end 230. The clamping end 210 is embedded in the clamping groove 111 and a hook structure is provided at the end of the clamping end 210. The hook structure is engaged with the hook structure of the clamping groove 111. The hook structure of the clamping end 210 is bent downward, and the hook structure of the clamping groove 111 that matches it is bent upward.

[0031] When positioning and installing the photovoltaic module 300, installation stability is the primary consideration. The stable installation of the photovoltaic module 300 needs to be sufficient to cope with various complex external environments and usage environments. In this embodiment, the positioning end 220 is provided with a positioning hole, which is used to combine with a positioning component to install and position the pressure block 200. The positioning component can be a bolt or other component. The bottom of the support end 230 is provided with an anti-skid structure 231. The anti-skid structure 231 can increase the friction between the entire pressure block 200 and the installation plane during installation, prevent the support end 230 from sliding, and increase the installation stability of the photovoltaic module 300. The anti-skid structure 231 can adopt an anti-skid tooth structure, an anti-skid texture structure, a concave-convex structure, etc.

[0032] In this embodiment, the top support frame 140 of the frame member 100 is mainly used to carry the photovoltaic assembly 300. Figure 1 and Figure 2 As shown, the top support frame 140 includes a bottom support 142 and a side support 141, and a glue overflow groove 143 is provided at the connection between the side support 141 and the bottom support 142. The glue overflow groove 143 can be filled with sealant to increase the sealing of the photovoltaic assembly 300 and the frame component 100. The bottom support 142 carries the photovoltaic assembly 300, and the side support 141 is bent in the direction of the photovoltaic assembly 300, and the end of the side support 141 is flush with the top surface of the photovoltaic assembly 300. The curved structure of the side support 141 can increase the structural strength of the top support frame 140 and form a good protection for the photovoltaic assembly 300. The end of the side support 141 is flush with the top surface of the photovoltaic assembly 300, which can avoid the side support 141 from blocking the upper surface of the photovoltaic assembly 300, reduce the loss of the light receiving area of ​​the photovoltaic assembly 300, and further improve the photoelectric conversion efficiency of the photovoltaic assembly 300.

[0033] It should be noted that, in this embodiment, Figure 3 As shown, the clamping groove 111 is arranged along the length direction of the frame member 100 and the clamping groove 111 is equal in length to the frame member 100. The clamping groove 111 has enough space to connect with the pressing block 200, so that a plurality of pressing blocks 200 can be installed on the frame member 100, thereby improving the stability of the installation of the photovoltaic module 300. At the same time, the pressing block 200 can also adjust the installation position in the clamping groove 111, so as to cope with complex installation environments.
