Description

Technical Field

[0001] This application relates to the field of photovoltaic installation technology, and more specifically, to a photovoltaic module installation structure and installation method. Background Technology

[0002] For the installation of double-glass frameless photovoltaic modules, the traditional method is to fix the photovoltaic module to the purlin with clamps. This installation method uses clamps to directly press the edge of the photovoltaic module, which can easily cause the photovoltaic module to break. In addition, care must be taken to avoid bumps and knocks on the edge of the frameless photovoltaic module during transportation.

[0003] For the installation of frameless double-glass photovoltaic modules with subframes, adjacent photovoltaic modules need to be laid flat on the purlins, with the subframes of the adjacent photovoltaic modules in contact with the purlins. Connecting components, such as clamping blocks, are installed between the subframes of the adjacent photovoltaic modules, and both sides of the connecting components simultaneously press the subframes on both sides to fix them to the purlins. Furthermore, at least two connecting components need to be installed on the same side of the photovoltaic module. Therefore, this installation structure and method makes it very inconvenient to install connecting components that are far from the location of the construction workers, and the photovoltaic modules cannot be stepped on, which reduces installation efficiency and makes disassembly and assembly difficult.

[0037] According to another aspect of this application, a photovoltaic module installation method is provided, using the photovoltaic module installation structure as described above, and the following steps:

[0042] The second component, on which the second photovoltaic module is installed, is laid flat on the purlin and close to the fourth connection of the third component;

[0043] The second component is pushed horizontally towards the fourth connecting part, so that the second connecting part is moved between the second flexible element and the purlin, and the second flexible element presses the second connecting part onto the purlin.

When the first connecting portion is interference-fitted to the first gap, a first interference force is formed; when the second connecting portion is interference-fitted to the second gap, a second interference force is formed. The interference force is greater than the second interference force, which achieves the following: the first component with the first photovoltaic module installed can be placed on the purlin first, then the third component can be fixed on the purlin and the third connecting part can press the first connecting part on the purlin. Finally, the second component with the second photovoltaic module installed can be placed on the purlin and pushed towards the third component, so that the second connecting part moves to below the fourth connecting part and is pressed by the fourth connecting part. This achieves the purpose of adjusting the installation sequence of the third component to before the installation of the second photovoltaic module, avoiding the impact of the installation of the second photovoltaic module on the installation of the third component, improving the convenience of photovoltaic module installation, and improving the installation efficiency of photovoltaic modules. In addition, it solves the problem in related technologies that for the installation of photovoltaic modules with subframes, the connecting component needs to be pressed on the subframe of the adjacent photovoltaic module, which makes the installation of the far-end connecting component inconvenient and the installation efficiency low.

[0059] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0060] For the installation of frameless double-glass photovoltaic (PV) modules with subframes, adjacent PV modules need to be laid flat on purlins, with the subframes of the adjacent PV modules in contact with the purlins. Connecting components, such as clamps, are installed between the subframes of the adjacent PV modules, and both sides of the connecting components simultaneously press the subframes together to secure them to the purlins. Furthermore, at least two connecting components need to be installed on the same side of the PV modules. Therefore, this installation structure and method makes it very inconvenient to install connecting components that are far from the location of the installers, and the PV modules cannot be stepped on, which reduces installation efficiency and makes disassembly and assembly difficult. Moreover, even when installing connecting components that are close together, since two PV modules have already been laid, the width of the PV modules must be overcome, resulting in a limitation on the width of the PV modules, increasing the number of PV modules that need to be laid, and reducing installation efficiency.

[0061] Therefore, to solve the above problems, such as Figure 1As shown in the figure, this application provides a photovoltaic module mounting structure, which includes: a first component 102 for fixed connection with a first photovoltaic module 101, the first component 102 including a first connecting portion 1021; a second component 202 for fixed connection with the second photovoltaic module 201, the second component 202 including a second connecting portion 2021; and a third component 3 for fixed connection with a purlin 12, the third component 3 including a third connecting portion 301 and a fourth connecting portion 302. The first flexible element 4 is attached to the third connecting part 301, and the second flexible element 5 is attached to the fourth connecting part 302. When the third member 3 is fixedly connected to the purlin 12, the first flexible element 4 and the purlin 12 form a first gap, and the second flexible element 5 and the purlin 12 form a second gap. The first connecting part 1021 is configured to be interference-fitted to the first gap, and the second connecting part 2021 is configured to be interference-fitted to the second gap. When the first connecting part 1021 is interference-fitted to the first gap, it forms a first interference force. When the second connecting part 2021 is interference-fitted to the second gap, it forms a second interference force. The first interference force is greater than the second interference force.

[0062] In this embodiment, the original plan required first laying the first component 102 with the first photovoltaic module 101 and the second component 202 with the second photovoltaic module 201 on the purlin 12, and then fixing the third component 3 between the first component 102 and the second component 202. The new plan is to first lay the photovoltaic module on one side (i.e., first lay the first component 102 with the first photovoltaic module 101) flat on the purlin 12, and then fix the third component 3 on the purlin 12. The third connecting part 301 on one side of the third component 3 presses against the first connecting part 1021 of the first component 102 on that side, thus completing the fixing of the first photovoltaic module 101. Then, the photovoltaic module on the other side (i.e., the second component 202 which will later have the second photovoltaic module 201) is laid flat on the purlin 12 and located on the other side of the third component 3, and pushed towards the third component 3, so that the second connecting part 2021 of the second component 202 is moved to below the fourth connecting part 302 of the third component 3, and the fourth connecting part 302 presses the second connecting part 2021 onto the purlin 12.

[0063] To ensure that the third connecting portion 301 and the fourth connecting portion 302 on both sides of the third component 3 can respectively press and fix the first connecting portion 1021 and the second connecting portion 2021 onto the purlin 12, a first flexible element 4 and a second flexible element 5 are respectively provided at the lower ends of the third connecting portion 301 and the fourth connecting portion 302. A first gap is formed between the first flexible element 4 and the purlin 12, and a second gap is formed between the second flexible element 5 and the purlin 12. The first connecting portion 1021 is located at the first gap and is interference-fitted with the first flexible element 4, and the second connecting portion 2021 is located at the second gap and is interference-fitted with the second flexible element 5.

[0064] Specifically, after installation, the interaction force between the first connecting part 1021 and the first flexible element 4 is the first interference force, and the interaction force between the second connecting part 2021 and the second flexible element 5 is the second interference force. When the first interference force and the second interference force are the same, the second connecting part 2021 on the second component 202 cannot be pushed flat into the lower part of the second flexible element 5 (that is, the distance between the second flexible element 5 and the purlin 12 does not meet the requirement for the second connecting part 2021 to be pushed in). Therefore, it is necessary to adjust the magnitude of the first interference force and the second interference force. Correspondingly, structurally, it is necessary to adjust the distance between the first flexible element 4 and the second flexible element 5 and the purlin 12, or adjust the height of the first connecting part 1021 and the second connecting part 2021, or adjust the distance between the third connecting part 301 and the fourth connecting part 302 and the purlin 12, etc.

[0065] When the spacing between the first flexible element 4 and the second flexible element 5 and the purlin 12 is adjusted, the first spacing can be made smaller than the second spacing. This ensures that even after the first flexible element 4 presses the first connecting part 1021 onto the purlin 126, the second spacing can still accommodate the insertion of the second connecting part 2021. Because the second spacing is larger, the interaction force between the second connecting part 2021 and the fourth connecting part 302 after installation will be less than the interaction force between the first connecting part 1021 and the third connecting part 301; that is, the second interference force is less than the first interference force.

[0066] The adjustment methods for the first and second spacing are as follows:

[0067] The distance between the third connecting part 301 and the purlin 12 is less than the distance between the fourth connecting part 302 and the purlin 12. The thickness of the first flexible element 4 and the second flexible element 5 is the same. Alternatively, the distance between the third connecting part 301 and the purlin 12 is equal to the distance between the fourth connecting part 302 and the purlin 12. The thickness of the first flexible element 4 is greater than the thickness of the second flexible element 5. That is, the first distance is less than the second distance.

[0068] Meanwhile, in this embodiment, the first flexible element 4 and the second flexible element 5 apply clamping force to the first connecting part 1021 and the second connecting part 2021 respectively, which can prevent structural deformation due to excessive pressure when the third component 3 is fixed to the purlin 12. At the same time, the use of flexible elements also facilitates the second connecting part 2021 to be pushed horizontally between the second flexible element 5 and the purlin 12. Since the installation condition that the second interference force is less than the first interference force needs to be met, in this embodiment, when the first connecting part 1021 is interference-connected to the first gap, the first flexible element 4 has a first compression amount, and when the second connecting part 2021 is interference-connected to the second gap, the second flexible element 5 has a second compression amount, and the first compression amount is greater than the second compression amount.

[0069] like Figure 1 As shown, the first connecting portion 1021 includes: a first surface for connecting to the first flexible element 4, and a second surface for connecting to the purlin 12; the second connecting portion 2021 includes: a third surface for connecting to the second flexible element 5; and a fourth surface for connecting to the purlin 12.

[0070] The first surface and the second surface form a third spacing (e.g. Figure 5 In b1), the third surface and the fourth surface form a fourth spacing (e.g., b1), Figure 5 In the diagram, the third spacing is greater than the first spacing (i.e., b1 is greater than b2), allowing the first flexible element 4 to have an interference fit with the first connecting part 1021. The fourth spacing is greater than the second spacing, allowing the second flexible element 5 to have an interference fit with the second connecting part 2021. To ensure that the second connecting part 2021 of the second component 202 can be smoothly pushed into the lower part of the second flexible element 5 without affecting the connection stability of the second component 202, the absolute value of the difference between the third spacing and the first spacing is greater than the absolute value of the difference between the fourth spacing and the second spacing (i.e., as shown in the diagram). Figures 4 to 6 As shown, |a1-c1-b1| is greater than |a2-c2-b2|. Furthermore, the third spacing is greater than the fourth spacing.

[0071] Since the second connecting part 2021 is installed between the second flexible element 5 and the purlin 12 in a flat pushing manner, the end of the second flexible element that is close to the second component 202 is set as a slope.

[0072] like Figure 1 and Figure 2As shown, to facilitate the installation of the first flexible element 4 and the second flexible element 5, in this embodiment, a retaining groove 303 is provided at the lower end of the third connecting part 301 and the fourth connecting part 302. The upper parts of the first flexible element 4 and the second flexible element 5 are engaged in the corresponding retaining groove 303, and the lower parts abut against the first connecting part 1021 and the second connecting part 2021, respectively. Specifically, the retaining groove 303 is a T-shaped groove. The upper parts of the first flexible element 4 and the second flexible element 5 extend from the narrow opening of the retaining groove 303 to the wide opening of the retaining groove 303. The part extending to the wide opening of the retaining groove 303 has an edge extending in a horizontal direction. The width of the edge is greater than the width of the narrow opening of the retaining groove 303, so that the first flexible element 4 and the second flexible element 5 will not easily detach from the retaining groove 303. Specifically, the first flexible element 4 and the second flexible element 5 are set as elastic sealing strips. In order to facilitate the second connecting part 2021 to be pushed flat into the lower part of the second flexible element 5, the second flexible element 5 needs to be more easily deformed under pressure. Therefore, in this embodiment, the second flexible element 5 is set as a hollow structure.

[0073] like Figure 3 As shown, the installation structure in this embodiment also includes an attachment plate 8 and a support plate 9, both of which are disposed between the first component 102 and the second component 202.

[0074] The auxiliary plate 8 is fixedly connected to the outer side of the first component 102, and the support plate 9 is fixedly connected to the auxiliary plate 8. The upper end of the support plate 9 is provided with a first wiring groove 10 for wiring 7; the third component 3 has a second wiring groove 13 corresponding to the first wiring groove 10.

[0075] Specifically, the first component 102 and the second component 202 have similar structures and can both be configured as subframes. The edges of the first photovoltaic module 101 and the second photovoltaic module 201 are fixed to the upper end of the subframe with double-sided adhesive. In this embodiment, the third component 3 needs to be fixedly connected to the purlin 12. Therefore, for the installation of a photovoltaic module on an adjacent side, generally only two third components 3 are involved. If only the second wiring groove 13 on the third component 3 is used as the wiring 7 structure, then the area between the two third components 3 will not be able to provide good support for the wiring 7.

[0076] Therefore, as Figure 3As shown, this embodiment adds an auxiliary plate 8 and a support plate 9. The auxiliary plate 8 is installed between the first component 102 and the second component 202, and also between the two third components 3. The first and second components are continuous structures, and their lengths are close to or the same as the length of the photovoltaic module. The installation of the auxiliary plate 8 and the support plate 9 must be carried out before the installation of the second component 202. After the first component 102 is installed, the auxiliary plate 8 can be fixed to the outside of the first component 102 by means of screws 11. Then the support plate 9 is fixed on the auxiliary plate 8 with the opening of the first wiring groove 10 facing upward. The first wiring groove 10 on the support plate 9 forms an installation space for the wiring 7 between the two third components 3. The first wiring groove 10 and the second wiring groove 13 jointly support the wiring 7, preventing the wiring 7 from falling onto the purlin 12, improving safety, and preventing wear on the wiring 7.

[0077] like Figure 1 and Figure 3 As shown, to further protect the wiring 7, the mounting structure in this embodiment also includes a cover plate 6. The cover plate 6 is a continuous structure and is snapped and fixed to the upper ends of the first component 102 and the second component 202 to close the first wiring groove 10 and the second wiring groove 13. Since the cover plate 6 is located between the first photovoltaic module 101 and the second photovoltaic module 201, in order to leave sufficient installation space for the cover plate 6, the installation position of the third component 3 needs to be lowered, that is, the connection position of the third component 3 with the first component 102 and the second component 202 needs to be lower than the upper surface of the photovoltaic module. Therefore, as Figure 1 As shown, the upper end of the first component 102 (the second component 202 has the same structure as the first component 102, and the first component 102 is used as an example for description) in this embodiment has a first mounting surface 1022 and a second mounting surface 1023, and the second mounting surface 1023 is lower than the first mounting surface 1022; the first photovoltaic module 101 is fixed on the first mounting surface 1022, and the first flexible element 4 is pressed and fixed on the second mounting surface 1023.

[0078] like Figure 3 As shown, to facilitate the connection between the first subframe and the subplate 8, the subplate 8 has a groove on the side facing away from the first subframe. The groove is a through groove structure. The upper and lower ends of the support plate 9, which are close to the subplate 8, are provided with an upper locking part 92 and a lower locking part 91, which respectively engage with the groove. The upper locking part 92 and the lower locking part 91 can be inserted into the groove by sliding along a direction perpendicular to the purlin 12, making the installation and removal of the support plate 9 convenient. The lower end face of the subplate 8 is flush with the lower end face of the first subframe, and the subplate 8 is in planar contact with the purlin 12, so that the weight of the subplate 8 can be directly applied to the purlin 12, improving structural stability.

[0079] Since the auxiliary plate 8 and the first auxiliary frame (referring to the first component) are connected by screws 11, the connection holes of the two need to be aligned during installation. In this embodiment, to make the alignment of the connection holes easier, as follows... Figure 4 As shown, the attachment plate 8 has an overlapping portion 81 and a support portion 82 on the side close to the first subframe. The overlapping portion 81 overlaps with the second mounting surface. During installation, the attachment plate 8 can be hung on the second mounting surface 1023 of the first component 102 (the second mounting surface 1023 is the part not connected to the first flexible element) using the overlapping portion 81. At this time, the connection holes of the attachment plate 8 and the first component 102 are aligned in height. Only the attachment plate 8 needs to be adjusted horizontally to align the two connection holes, and then the screw 11 can be screwed in to complete the installation and fixation of the attachment plate 8. Since pressure needs to be applied to the attachment plate 8 when screwing in the screw 11, a support portion 82 is also provided on the attachment plate 8 to avoid deformation caused by excessive pressure. The support portion 82 abuts against the first component 102 and is set close to the screw 11. The support portion 82 strengthens the structural strength of the attachment plate 8 at the screw 11 connection.

[0080] This embodiment describes the snap-fit ​​structure of the cover plate 6, the auxiliary plate 8, and the support plate 9:

[0081] like Figure 1 and Figure 4 As shown, the lower end of the cover plate 6 has two downwardly extending support walls that extend along the length of the cover plate 6. The outer side of the support wall (i.e., the side facing the first photovoltaic module 101 and the second photovoltaic module 201) has a first hook-and-connection portion. The upper ends of the attachment plate 8 and the support plate 9 have second hook-and-connection portions that engage with the first hook-and-connection portions. The upper ends of the support walls, attachment plate 8, and support plate 9 all have a certain degree of deformation capability. When installing the cover plate 6, applying downward pressure to the cover plate 6 will cause the first and second hook-and-connection portions to engage, making installation convenient.

[0082] According to another aspect of this application, a photovoltaic module installation method is provided, using the above-described photovoltaic module installation structure, and comprising the following steps:

[0083] The first photovoltaic module 101 is fixedly connected to the first component 102;

[0084] The first component 102, on which the first photovoltaic module 101 is installed, is laid flat on the purlin 12;

[0085] The third component 3 is installed on the purlin 12, and the first flexible element 4 attached to the third connecting part 301 is pressed against the first connecting part 1021 of the first component 102;

[0086] The second photovoltaic module 201 is fixedly connected to the second component 202;

[0087] The second component 202, on which the second photovoltaic module 201 is installed, is laid flat on the purlin 12 and close to the fourth connection part 302 of the third component 3;

[0088] The second component 202 is pushed horizontally towards the fourth connecting part 302, so that the second connecting part 2021 is moved between the second flexible element 5 and the purlin 12, and the second flexible element 5 presses the second connecting part 2021 onto the purlin 12.

[0089] In this embodiment, the first photovoltaic module 101 is installed before the second photovoltaic module 201, and the second photovoltaic module 201 is installed adjacent to the first photovoltaic module 101 and after it. Therefore, the first photovoltaic module 101 and the second photovoltaic module 201 are not limited to photovoltaic modules in specific locations. Thus, adjacent photovoltaic modules are installed in the manner described above, and the above steps are repeated until the installation of several photovoltaic modules across the entire building surface is completed.

[0090] Furthermore, before installing the second photovoltaic module 201, the process includes fixing the auxiliary plate 8 to the first component 102, fixing the first wiring groove 10 of the support plate 9 upward and snapping it into the auxiliary plate 8; arranging the wiring 7 on the support plate 9 and the third component 3; and after installing the second photovoltaic module 201, snapping the cover plate 6 into the support plate 9 and the auxiliary plate 8.

[0091] In this embodiment, when laying adjacent photovoltaic modules, the first component 102 of the first photovoltaic module 101 is first fixed to the purlin 12 via the third component 3, and the second component 202 of the second photovoltaic module 201 is fixed to the third component 3 by pushing and pressing. By setting the cover plate 6, the gap between adjacent photovoltaic modules is reduced, and the third component 3 is hidden under the cover plate 6, making the laying surface aesthetically pleasing. At the same time, wiring 7 can also be arranged between the cover plate 6 and the support plate 9, and between the cover plate 6 and the third component 3. The support plate 9 and the third component 3 hold the wiring 7, preventing the wiring 7 from falling onto the purlin 12, improving safety, and preventing wear on the wiring 7.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
