[0035] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0036] Reference below Figure 1-Figure 7 A photovoltaic installation assembly 10 and a photovoltaic system according to an embodiment of the present application are described.

[0037] like Figure 1-Figure 7 As shown, the photovoltaic installation assembly 10 of the embodiment of the present application includes: a purlin 110 and a buckle 120.

[0038] The purlin 110 can be installed on the main axis of the photovoltaic system, and the purlin 110 extends in a direction intersecting the main axis, and the purlin 110 is used to support the photovoltaic module 20. For example, in the photovoltaic system, a plurality of purlins 110 are arranged and distributed at intervals along the length direction of the main axis, and each photovoltaic module 20 is installed between two adjacent purlins 110.

[0039] The purlin 110 may be a metal part, or a plastic part with sufficient rigidity and strength.

[0040] like Figure 2 As shown, the purlin 110 in the embodiment of the present application includes: a support plate 112 and a connecting plate 111 .

[0041] The support plate 112 is used to support the photovoltaic assembly 20 . For example, the support plate 112 may be generally arranged upward to support the photovoltaic assembly 20 . In actual implementation, the frame of the photovoltaic assembly 20 may overlap the support plate 112 in the vertical direction.

[0042] like Figure 2 As shown, the connecting plate 111 is connected to the supporting plate 112 , and the connecting plate 111 and the supporting plate 112 may be integrated into one body, for example, the connecting plate 111 and the supporting plate 112 may be sheet metal parts connected by bending.

[0043] Of course, the purlin 110 may also include other panels, such as Figure 2 In the embodiment, the purlin 110 may further include a mounting plate 113, and the mounting plate 113 is used to connect with the main shaft. For example, the mounting plate 113 may be supported on the upper surface of the main shaft, and the mounting plate 113 may also be used to connect with the connection hole connected to the lower support of the purlin 110. The connecting plate 111, the supporting plate 112 and the mounting plate 113 may be integrated into one. Figure 2 In the illustrated embodiment, the connecting plate 111 , the supporting plate 112 and the mounting plate 113 are sheet metal parts connected by bending.

[0044] like Figure 2 As shown, the normal line of the support plate 112 intersects the normal line of the connection plate 111. In other words, the connection plate 111 is a plate body on the purlin 110 that is not coplanar with the support plate 112, and the orientation of the connection plate 111 is different from the orientation of the support plate 112. For example, the normal line of the connection plate 111 can be generally in the horizontal direction, and the normal line of the support plate 112 can be generally in the vertical direction.

[0045] like Figure 2 and Figure 3 As shown, the connecting plate 111 of the purlin 110 is provided with a clamping portion 1111, and the buckle 120 has a connecting portion 121 and a locking portion 122. The connecting portion 121 is used to connect with the frame of the photovoltaic module 20, and the locking portion 122 is used to clamp with the clamping portion 1111.

[0046] In other words, the photovoltaic assembly 20 can be installed on the purlin 110 through the buckle 120. That is, the buckle 120 can be pre-installed on the photovoltaic assembly 20 to form a whole, and then the whole is installed on the purlin 110.

[0047] like Figure 4-Figure 7 As shown, in actual implementation, the buckle 120 can use rivets to connect the connecting part 121 to the frame of the photovoltaic module 20, and then the locking part 122 of the buckle 120 is clamped with the clamping part 1111, while also realizing that the photovoltaic module 20 is supported on the support plate 112 of the purlin 110.

[0048] Of course, the buckle 120 can also be connected to the frame of the photovoltaic component 20 in other ways, such as gluing.

[0049] It is understandable that, in the above installation method, the support surface between the photovoltaic module 20 and the purlin 110 is not coplanar with the clamping position between the buckle 120 and the purlin 110 .

[0050] In the related art, in order to reduce the use of threaded connectors, some clip-on structures for connecting photovoltaic modules and purlins are also designed. However, considering that the photovoltaic modules and purlins themselves are directly in contact with the supporting surface, these clip-on structures in the related art are all implemented by clipping on the supporting surface between the photovoltaic modules and the purlins.

[0051] Through research, the inventors found that this kind of clip-on method in the related art is easy to damage the photovoltaic module when installing the photovoltaic module on the purlin or removing the photovoltaic module from the purlin, and has low safety. At the same time, this kind of clip-on method in the related art often requires processing a special structure on the frame of the photovoltaic module, that is, the related solution cannot be applied to universal photovoltaic modules, and the cost of independent mold opening or processing is high.

[0052] According to this, if Figure 6 and Figure 7 As shown, in the technical solution of the present application, by designing the above-mentioned assembly method, the support surface between the photovoltaic module 20 and the purlin 110 is not coplanar with the clamping position between the buckle 120 and the purlin 110. This design avoids the photovoltaic module 20 from being damaged when the buckle 120 and the purlin 110 are clamped and installed or disassembled.

[0053] At the same time, the clamping method in the technical solution of this application does not require processing of special structures on the frame of the photovoltaic module. Figure 2 As shown, in this solution, a clamping portion 1111 is processed on the connecting plate 111 of the purlin 110 , and the processing procedure is simple, and it can be applied to universal photovoltaic modules, and no independent mold is required, and the processing cost is low.

[0054] like Figure 4-Figure 7As shown, during the installation process of the photovoltaic component 20 in the embodiment of the present application, the buckle 120 uses rivets or other fastening methods to connect the connecting part 121 to the frame of the photovoltaic component 20, and the photovoltaic component 20 and the buckle 120 form a whole.

[0055] like Figure 1 and Figure 2 As shown, the stopper 122 of the buckle 120 is engaged with the engaging portion 1111 of the purlin 110, and the engaging portion 1111 is located on the purlin connecting plate 111 which is not coplanar with the frame of the photovoltaic module 20. By designing the engaging position, the photovoltaic module 20 is not easily damaged when installed on the purlin 110.

[0056] like Figure 6 As shown, the two side frames of the photovoltaic module 20 are respectively fastened with a pair of buckles 120 in opposite directions. When fastening, the stopper portions 122 of the buckles 120 on both sides need to be fastened with the fastening portions 1111 on the two purlins 110. In actual implementation, the frame on one side of the photovoltaic module 20 is fastened with the buckle 120, so that the buckle 120 is fastened with the fastening portion 1111 on the connecting plate 111 on one side of a purlin 110, and at the same time, the frame on the other side of the photovoltaic module 20 is fastened with another buckle 120 in the opposite direction, so that this buckle 120 is fastened with the fastening portion 1111 on the connecting plate 111 on the opposite side of another parallel purlin 110, so as to achieve complete fixation of the position of the photovoltaic module 20.

[0057] When disassembling the photovoltaic module 20, the buckle 120 and the purlin 110 can be quickly disassembled through the elastic deformation of the buckle 120. The disassembly part is located on the side of the plane of the connecting plate 111 of the purlin 110, which is not coplanar with the supporting surface between the photovoltaic module 20 and the purlin 110, so that the photovoltaic module 20 is not easily damaged during the disassembly process.

[0058] According to the photovoltaic installation component 10 of the present application, the photovoltaic component 20 and the purlin 110 are assembled by installing the clip 120 on the connecting plate 111 which is not coplanar with the support plate 112 of the purlin 110. This assembly method is not easy to damage the photovoltaic component, is suitable for universal photovoltaic components, and has low cost.

[0059] In some embodiments, Figure 3 As shown, the buckle 120 may include an elastic arm 123, which may be connected between the connecting portion 121 and the stopper portion 122 of the buckle 120. The elastic arm 123 may be bent with the connecting portion 121 of the buckle 120, and the elastic arm 123 may be arranged opposite to the connecting plate 111 of the purlin 110.

[0060] The elastic arm 123 may be a sheet metal or plastic with a certain elasticity. The elastic arm 123 can clamp the buckle 120 and the purlin 110 by elastic force during installation. In actual implementation, during installation, the elastic arm 123 of the buckle 120 allows the stopper 122 of the buckle 120 to enter the clamping part 1111 of the purlin 110 to form a clamping fit, thereby assisting in completing the installation of the buckle 120 and the purlin 110.

[0061] When the photovoltaic assembly 20 is disassembled, a simple tool can be used to push the elastic arm 123 to deform the elastic arm 123. The deformation can make the locking portion 122 of the buckle 120 disengage from the locking portion 1111 of the purlin 110, thereby realizing the rapid disassembly of the photovoltaic assembly 20.

[0062] In some embodiments, Figure 3 As shown, a weakened groove 124 may be provided between the connecting portion 121 and the stopper portion 122 of the buckle 120. By providing the weakened groove 124 between the connecting portion 121 and the stopper portion 122 of the buckle 120, the buckle 120 may be bent or deformed under certain conditions, thereby increasing the elasticity and adaptability of the buckle 120. Specifically, the weakened groove 124 is processed with a circular chamfer, and such a design may reduce the stress concentration between the elastic arm 123 and the stopper portion 122 of the buckle 120.

[0063] In some embodiments, Figure 3 As shown, the stopper 122 may include a base plate 1221 and a hook 1222 , wherein the base plate 1221 is connected to the elastic arm 123 , and the hook 1222 is connected to the base plate 1221 .

[0064] In actual implementation, the base plate 1221 can effectively transfer force to the connecting portion 121 by combining with the elastic arm 123, so that the stopper portion 122 has load-bearing capacity. The design of the hook 1222 enables the stopper portion 122 to be engaged with the groove of the engaging portion 1111 of the purlin 110. The buckle 120 slides on the connecting plate 111 of the purlin 110, and the hook 1222 can be positioned at the position of the groove of the engaging portion 1111, generating engagement and self-adaptation, so that the hook 1222 can be effectively fixed on the purlin 110, and the buckle 120 and the purlin 110 are firmly connected, and the photovoltaic module 20 is installed on the purlin 110.

[0065] In some embodiments, Figure 3 As shown, the hook 1222 is provided with a guide surface 12221 , and the vertical height from the guide surface 12221 to the base plate 1221 gradually increases from an end away from the elastic arm 123 to an end close to the elastic arm 123 .

[0066] The design of the guide surface 12221 allows the buckle 120 to be accurately guided into the clamping portion 1111 of the purlin 110 during the installation process. Since the height of the guide surface 12221 gradually increases, when the buckle 120 is inserted into the clamping portion 1111 of the purlin 110, the buckle 120 can be gradually guided to be inserted into the purlin 110 in the correct direction, and the clamping at the correct position can be achieved through guidance.

[0067] In some embodiments, Figure 1 As shown, the engaging portion 1111 of the purlin 110 includes a plurality of grooves, and the locking portion 122 of the buckle 120 includes a plurality of hooks 1222 , which correspond one-to-one to the plurality of grooves of the engaging portion 1111 of the purlin 110 .

[0068] Multiple grooves on the same side of the purlin 110 cooperate with the corresponding stopper 122 of the buckle 120 to achieve multiple fixations, so that the photovoltaic assembly 20 can be firmly installed on the purlin 110. Multiple fixations can also increase the service life of the photovoltaic installation assembly 10. When a certain clamping point fails, another clamping point can still provide the function of supporting and positioning the photovoltaic installation assembly 10.

[0069] In some embodiments, Figure 2 As shown, the clamping portion 1111 of the purlin 110 is close to the end of the length direction of the purlin 110. During the disassembly process of the photovoltaic module 20, the tool can be easily inserted from the outside into the space between the connecting plates 111 and the mounting plate 113 on both sides of the purlin 110, and clamped between the elastic arm 123 and the connecting plate 111 of the purlin 110, and the elastic arm 123 is pushed to deform, and the deformation causes the clamping portion 122 of the buckle 120 to be separated from the clamping portion 1111 of the purlin 110, and the disassembly of the photovoltaic module 20 is completed, which saves the time of finding a suitable angle and position during the disassembly process, and improves the convenience and efficiency of the operation.

[0070] In some embodiments, Figure 6 and Figure 7 As shown, the connection part 121 of the buckle 120 is in contact with the surface of the support plate 112 of the purlin 110 facing the photovoltaic module 20, and the buckle 120 can be clamped between the support plate 112 of the purlin 110 and the frame of the photovoltaic module 20. The upper and lower planes of the connection part 121 are respectively in contact with the lower surface of the frame of the photovoltaic module 20 and the upper surface of the support plate 112 of the purlin 110. During the installation and removal process of the photovoltaic module 20, the connection part 121 of the buckle 120 can reduce the contact area between the support plate 112 of the purlin 110 and the frame of the photovoltaic module 20, so that the photovoltaic module 20 is not easily damaged due to the contact between the two surfaces.

[0071] In some embodiments, Figure 2As shown, the purlin 110 may include two connecting plates 111 arranged opposite to each other, each connecting plate 111 is connected to a support plate 112, and each connecting plate 111 is provided with a clamping portion 1111. Figure 4 and Figure 6 As shown, the frame of the photovoltaic assembly 20 cooperates with the snap-fitting parts 1111 of different purlins 110 through the snap-fitting parts 120 installed in opposite directions on both sides of the frame of the photovoltaic assembly 20, so as to achieve complete fixation in position.

[0072] The photovoltaic mounting assembly 10 of the above embodiment realizes the assembly of the photovoltaic assembly 20 and the purlin 110 by installing the buckle 120 on the connecting plate 111 which is not coplanar with the supporting plate 112 of the purlin 110. This assembly method is not easy to damage the photovoltaic assembly. At the same time, the groove processing process of the clamping part 1111 of the connecting plate 111 of the purlin 110 in the above assembly method is simple, and it is suitable for universal photovoltaic assemblies and has low cost.

[0073] The embodiment of the present application also provides a photovoltaic system.

[0074] like Figure 4-Figure 7 As shown, the photovoltaic system includes: a photovoltaic installation assembly 10 and a photovoltaic assembly 20. The photovoltaic assembly 20 is installed above the support plate 112 of the purlin 110, and the frame of the photovoltaic assembly 20 is connected to the connecting portion 121 of the buckle 120.

[0075] The photovoltaic installation assembly 10 may be the photovoltaic installation assembly 10 of any of the above-mentioned embodiments.

[0076] In some embodiments, the connection portion 121 of the buckle 120 can be pre-fastened to the frame of the photovoltaic module 20 by rivets or other methods, such as Figure 7 As shown, there should be bolt connection or other fastening connection between the frame of the photovoltaic module 20 and the connecting portion 121 of the buckle 120. The fasteners are not shown in the figure, but they should exist in actual implementation. The buckle 120 is then snap-fitted with the purlin 110 to achieve the installation of the photovoltaic module 20 on the purlin 110.

[0077] According to the photovoltaic system provided in the embodiment of the present application, the photovoltaic component 20 and the purlin 110 are assembled by installing the clip 120 on the connecting plate 111 which is not coplanar with the support plate 112 of the purlin 110. This assembly method is not easy to damage the photovoltaic component 20, is suitable for universal photovoltaic components, and has low cost.
