Description

Technical Field

[0001] This application relates to the field of photovoltaic mounting systems, and more particularly to a rotatable and adjustable adapter and a photovoltaic mounting system. Background Technology

[0002] Photovoltaic brackets are an indispensable and important component of solar photovoltaic power generation systems, used to support, fix, and rotate photovoltaic modules.

[0003] In related technologies, photovoltaic support structures include crossbeams, columns, and purlins. The columns are fixedly connected to the crossbeams via connectors to support the crossbeams. The crossbeams are fixed to the purlins via adapters, allowing the purlins to overlap the crossbeams and support the purlins. The purlins are used for the installation of photovoltaic modules.

[0004] However, in practical applications, with the diversification of photovoltaic module sizes, the relatively fixed hole positions for purlin installation on the crossbeams cannot meet the needs of flexible on-site adjustments, thus requiring improvement. Utility Model Content

[0005] To facilitate flexible adjustments on-site, this application provides a rotatable and adjustable adapter assembly.

[0006] The rotatable and adjustable adapter assembly provided in this application adopts the following technical solution:

[0007] A rotatable adjustable adapter assembly includes an adapter, a snap-fit ​​component, and a fastener. The adapter includes a first adapter portion and a second adapter portion. The upper end of the first adapter portion is rotatably connected to a purlin, and the second adapter portion is located at the lower end of the first adapter portion. The snap-fit ​​component snaps into and slides onto a crossbeam. The snap-fit ​​component is detachably connected to the second adapter portion via the fastener, so that the crossbeam is pressed between the snap-fit ​​component and the second adapter portion.

[0008] By adopting the above technical solution, in practical applications, workers can disassemble the snap-fit ​​component and the second adapter using fasteners to release the pressure on the crossbeam. Then, the snap-fit ​​component is slid to move the first adapter, causing the purlin installed on the first adapter to move, thereby adjusting the distance between the two purlins to suit photovoltaic modules of different sizes. The operation is simple and convenient, thus facilitating flexible adjustments on site.

[0009] Preferably, the lower end of the first adapter is arc-shaped.

[0010] By adopting the above technical solution, and by setting the lower end of the first transition part to be arc-shaped, the stress concentration at the corner can be effectively dispersed.

[0011] Preferably, the adapter further includes a reinforcing part, which is disposed in the first adapter.

[0012] By adopting the above technical solution and setting up a reinforcement section, the structural strength of the first transition section is guaranteed.

[0013] Preferably, the upper end of the first adapter is provided with a rounded corner.

[0014] By adopting the above technical solution and setting rounded corners, the stability of rotation between the first transition part and the purlin is ensured.

[0015] Preferably, one side of the snap-fit ​​component is provided with anti-slip texture, which abuts against the crossbeam and the second transition portion.

[0016] By adopting the above technical solution and setting anti-slip texture, the connection between the snap-fit ​​component and the crossbeam and between the snap-fit ​​component and the second adapter is made tighter, thereby improving the stability of the installation between the purlin and the crossbeam.

[0017] Preferably, the fastener includes a fastening bolt and a fastening nut, one end of the fastening bolt passing through the snap-fit ​​member and the second adapter and being threadedly connected to the fastening nut.

[0018] By adopting the above technical solution and setting fastening bolts and fastening nuts, a detachable connection between the snap-fit ​​part and the second adapter part can be achieved. The structure is simple and the operation is convenient.

[0019] Preferably, a limiting groove is provided on the side of the snap-fit ​​member away from the second adapter, and the fastening bolt is confined in the limiting groove to restrict the rotation of the fastening bolt.

[0020] By adopting the above technical solution and setting a limiting groove, the rotation of the fastening bolt is restricted, so as to facilitate the connection between the fastening nut and the fastening bolt.

[0021] Preferably, the second adapter has a through hole along its length, and the fastening bolt passes through the through hole.

[0022] By adopting the above technical solution and setting through holes, the degree of freedom in the installation between the crossbeam and the purlin is improved.

[0023] Preferably, the rotatable adjustable adapter assembly further includes a connector, which includes a connecting bolt and a connecting nut. The connecting bolt passes through the purlin and the first adapter and is threadedly connected to the connecting nut.

[0024] By adopting the above technical solution and setting connecting bolts and connecting nuts, a rotatable connection between the first adapter and the purlin is achieved, so as to facilitate the installation and disassembly of the first adapter and the purlin.

[0025] Secondly, this application provides a photovoltaic bracket.

[0026] The photovoltaic support system provided in this application adopts the following technical solution:

[0027] A photovoltaic mounting bracket includes the rotatable and adjustable adapter assembly described above.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The operator uses fasteners to disassemble the snap-fit ​​part from the second adapter part to release the pressure on the crossbeam. Then, the snap-fit ​​part is slid to move the first adapter part, so that the purlin installed on the first adapter part can move to adjust the distance between the two purlins to suit photovoltaic modules of different sizes. The operation is simple and convenient, thus making it easy to adapt to the needs of flexible on-site adjustments.

[0030] 2. By setting the lower end of the first transition section to an arc shape, the stress concentration at the corner can be effectively dispersed;

[0031] 3. By setting a limiting groove, the rotation of the fastening bolt is restricted, so as to facilitate the connection between the fastening nut and the fastening bolt. Attached Figure Description

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0039] This application discloses a rotatable and adjustable adapter assembly.

[0040] Reference Figure 1 and Figure 2 The rotatable adjustable adapter assembly includes an adapter 1, a snap-fit ​​2, and a fastener 3. The adapter 1 includes a first adapter part 11 and a second adapter part 12. The upper end of the first adapter part 11 is rotatably connected to the purlin 5, and the second adapter part 12 is integrally connected to the lower end of the first adapter part 11.

[0041] The shape of the snap-fit ​​2 is adapted to the shape of the crossbeam 6, so that the snap-fit ​​2 snaps and slides in the crossbeam 6. The snap-fit ​​2 is detachably connected to the second adapter 12 by the fastener 3, so that the crossbeam 6 is pressed between the snap-fit ​​2 and the second adapter 12.

[0042] In practical applications, workers use fasteners 3 to disassemble the snap-fit ​​part 2 from the second adapter part 12, thereby releasing the pressure on the crossbeam 6. Then, the snap-fit ​​part 2 is slid, causing the first adapter part 11 to slide, allowing the purlin 5 installed on the first adapter part 11 to move and adjust the distance between the two purlins 5 to accommodate photovoltaic modules of different sizes. This operation is simple and convenient, facilitating flexible adjustments on-site. Simultaneously, because the first adapter part 11 is rotatably connected to the purlin 5, it can accommodate installations of the crossbeam 6 and purlin 5 at different angles.

[0043] In some embodiments, the lower end of the first adapter 11 is arranged in an arc shape, which can effectively disperse the stress concentration at the corner, thereby improving the overall compressive strength and stability of the adapter 1.

[0044] Reference Figure 2 In some embodiments, the adapter 1 further includes a reinforcing part 13, which is integrally connected to the first adapter 11 to support the first adapter 11, especially the arc-shaped portion of the first adapter 11, to ensure the structural strength of the first adapter 11 and thus improve the stability of the adapter 1 in use. The adapter 1 is manufactured using a die-casting process, requiring only one fastener 3 for fixation, thereby shortening installation time and improving installation efficiency.

[0045] In some embodiments, the upper end of the first adapter 11 is provided with a rounded corner 14 to avoid interference between the first adapter 11 and the purlin 5 when the first adapter 11 rotates, so as to ensure the stability of the rotation between the first adapter 11 and the purlin 5.

[0046] In some embodiments, one side of the snap-fit ​​2 is provided with anti-slip texture 21, which simultaneously abuts against the inner side of the crossbeam 6 and one side of the second adapter 12, making the connection between the snap-fit ​​2 and the crossbeam 6 and between the snap-fit ​​2 and the second adapter 12 more compact, thereby improving the stability of the installation between the purlin 5 and the crossbeam 6.

[0047] In some embodiments, the fastener 3 includes a fastening bolt 31 and a fastening nut 32. One end of the fastening bolt 31 passes through the snap-fit ​​member 2 and the second adapter 12, and the other end abuts against the snap-fit ​​member 2. The fastening nut 32 is threadedly connected to the fastening bolt 31 and abuts against the side of the second adapter 12 away from the crossbeam 6, so as to realize the detachable connection between the snap-fit ​​member 2 and the second adapter 12. The structure is simple and the operation is convenient.

[0048] In some embodiments, a limiting groove 22 is provided on the side of the snap-fit ​​member 2 away from the second adapter 12, and the fastening bolt 31 is limited in the limiting groove 22 to restrict the rotation of the fastening bolt 31. In this way, the connection between the fastening bolt 31 and the fastening nut 32 can be realized by simply rotating the fastening nut 32, thereby facilitating the installation and removal of the fastening nut 32 and the fastening bolt 31.

[0049] Reference Figure 1 and Figure 2 In some embodiments, the second adapter 12 has a through hole 15 along its own length direction, and the fastening bolt 31 passes through the through hole 15 to improve the degree of freedom of installation between the crossbeam 6 and the purlin 5, and can eliminate a certain amount of installation error.

[0050] In some embodiments, the rotatable adjustment adapter assembly further includes a connector 4, which includes a connecting bolt 41 and a connecting nut 42. One end of the connecting bolt 41 passes through the purlin 5 and the first adapter 11, and the other end abuts against one side of the purlin 5. Meanwhile, the connecting nut 42 is threadedly connected to the connecting bolt 41 and abuts against the other side of the purlin 5, so as to realize the rotatable connection between the first adapter 11 and the purlin 5, so as to facilitate the installation and disassembly of the first adapter 11 and the purlin 5.

[0051] The implementation principle of this embodiment is as follows: In practical applications, workers use fasteners 3 to disassemble the snap-fit ​​part 2 from the second adapter part 12 to release the pressure on the crossbeam 6. Then, the snap-fit ​​part 2 is slid, causing the first adapter part 11 to slide, thereby moving the purlin 5 installed on the first adapter part 11 to adjust the distance between the two purlins 5 to accommodate photovoltaic modules of different sizes. This operation is simple and convenient, thus easily adapting to the needs of flexible on-site adjustments. At the same time, since the first adapter part 11 is rotatably connected to the purlin 5, it can be used for installation of the crossbeam 6 and the purlin 5 at different angles.

[0052] This application also discloses a photovoltaic bracket.

[0053] Reference Figure 3 The photovoltaic support includes a column 7 and a rotatable and adjustable adapter assembly as described in the above embodiment. The column 7 is installed on the crossbeam 6, and the photovoltaic module is fixedly connected between two adjacent purlins 5.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
