Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, specifically to a bidirectional mounting bracket for photovoltaic modules. Background Technology

[0002] Photovoltaic modules are generally rectangular in shape and require mounting brackets for fixation. Existing mounting brackets are made of assembled aluminum frames, resulting in slow assembly and disassembly, thus affecting the practicality of the mounting system. Summary of the Invention

[0003] This utility model provides a bidirectional mounting bracket for photovoltaic modules to solve the problem of insufficient practicality of existing photovoltaic module mounting brackets.

[0004] This utility model provides a bidirectional mounting bracket for photovoltaic modules, including a first bracket and a second bracket hinged to each other at one end, and the other ends of the first bracket and the second bracket respectively connected to a third bracket at a preset angle; a limiting lock is provided between the first bracket and the third bracket, and between the second bracket and the third bracket; a base is sleeved on the bottom end of the third bracket, the base including a through hole and / or a positioning pin; at least two sets of assemblies on the first bracket and the second bracket constitute the mounting part of the bidirectional mounting bracket; the mounting part also includes a fourth bracket disposed between two adjacent first brackets or two adjacent second brackets.

[0005] In this invention, the first and second brackets are hinged together at a preset angle, making the mounting bracket for installing two photovoltaic modules a "one-piece" structure. A third bracket then supports the assembly of the first and second brackets. A fourth bracket connects and fixes adjacent mounting parts. This one-piece structure not only increases the number of photovoltaic modules that can be installed, but the hinged structure also facilitates assembly and disassembly. Furthermore, the overall mounting bracket structure is simple, effectively improving the practicality of the photovoltaic module mounting bracket.

[0006] Optionally, the fourth bracket includes a limiting hole for insertion with a limiting block.

[0007] In this embodiment, a limiting block is used to fix the installation position of the photovoltaic module in the slope formed by the first or second bracket, so as to prevent the photovoltaic module from moving downward.

[0008] Optionally, the limiting block includes a limiting body, an L-shaped positioning plate, and a connector. One side of the L-shaped positioning plate is welded to the side of the limiting body, and the connector is used to pass through the limiting hole on the other side of the L-shaped positioning plate and connect to the fourth bracket.

[0009] In this embodiment, the limiting body of the limiting block is used to abut against the frame of the photovoltaic module, and then the position of the limiting block is fixed by an L-shaped positioning plate. Finally, it is fixed to the fourth bracket by a connector, or it can be fixed to the first bracket or the second bracket if needed.

[0010] Optionally, a cover plate is also included, the cover plate having an arc-shaped cross-section, used to connect to the top end of the mounting portion, and the arc surface of the cover plate facing the mounting portion.

[0011] In this embodiment, a cover plate with an arc-shaped cross section is installed at the hinged position between the first bracket and the second bracket, i.e., at the top of the mounting part, to prevent wind, sand or rainwater from entering the hinged structure and affecting normal use or its service life.

[0012] Optionally, the limit lock includes: a sleeve and a pair of latches, the two latches being screwed to both ends of the sleeve, the sleeve being rotated clockwise to bring the two latches closer to each other, and the other ends of the two latches being inserted into the first bracket and the third bracket respectively, or respectively into the second bracket and the third bracket.

[0013] In this design, a sleeve-type limit lock is set. By rotating the sleeve in the forward direction, the two bolts at both ends are brought closer to each other, that is, the straight-line distance between the first bracket and the third bracket, or the straight-line distance between the second bracket and the third bracket is brought closer. Conversely, rotating the sleeve in the reverse direction, the two bolts at both ends are moved away from each other, that is, the first bracket and the third bracket are pushed apart, or the second bracket and the third bracket are pushed apart.

[0014] In summary, the overall beneficial effects of this utility model are as follows: The present invention provides a bidirectional mounting bracket for photovoltaic modules, which not only increases the number of photovoltaic modules that can be installed, but also facilitates the assembly and disassembly of the modules. In addition, the entire mounting bracket has a simple structure, which effectively improves the practicality of the photovoltaic module mounting bracket. Attached Figure Description

[0017] The technical solutions in the embodiments of the application will now be clearly and completely described with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0018] Photovoltaic modules are generally cuboid in structure and require mounting brackets for fixation. Existing mounting brackets are made of assembled aluminum frames, resulting in slow assembly and disassembly, thus affecting their practicality. Therefore, this invention provides a bidirectional mounting bracket for photovoltaic modules, which will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a bidirectional mounting bracket for photovoltaic modules, including a first bracket 1 and a second bracket 2 hinged to each other at one end, and the other ends of the first bracket 1 and the second bracket 2 respectively connected to a third bracket 3 at a preset angle; a limiting lock 5 is provided between the first bracket 1 and the third bracket 3, and between the second bracket 2 and the third bracket 3; a base 31 is sleeved on the bottom end of the third bracket 3, the base 31 includes a through hole and / or a positioning pin; at least two sets of assemblies on the first bracket 1 and the second bracket 2 constitute the mounting part of the bidirectional mounting bracket; the mounting part also includes a fourth bracket 4 disposed between two adjacent first brackets 1 or two adjacent second brackets 2.

[0020] As described above, the bidirectional mounting bracket provided by this utility model has a first bracket 1 and a second bracket 2 hinged together at a preset angle, making the mounting bracket for installing two photovoltaic modules an "integrated" structure. This integrated structure allows two mounting components to be installed "back-to-back" on the bracket simultaneously. After fixing the hinge angle, a third bracket 3 is used to support the combination of the first bracket 1 and the second bracket 2, so that the photovoltaic modules are fixed at a certain height relative to the ground after installation. To increase the stability of the mounting bracket, after setting at least two sets of the aforementioned integrated mounting brackets, a fourth bracket 4 is set between adjacent sets, that is, the fourth bracket 4 is used as a connecting rod to fix the aforementioned two adjacent mounting parts. This integrated structure not only increases the number of photovoltaic modules that can be installed, but also facilitates the assembly and disassembly of the entire mounting bracket.

[0021] In addition, the preset angles between the first bracket 1 and the third bracket 3, and between the second bracket 2 and the third bracket 3, can be determined according to the actual installation ground parameters. For example, if the installation ground is horizontal, the preset angle is 90°. If the installation ground is inclined, the final preset angle value needs to be calculated based on the actual inclination angle.

[0022] The aforementioned fourth bracket 4 includes a limiting hole for insertion into the limiting block 6. The limiting block 6 includes a limiting body 61, an L-shaped positioning plate 62, and a connector 63. One side of the L-shaped positioning plate 62 is welded to the side of the limiting body 61, and the connector 63 is used to pass through the limiting hole on the other side of the L-shaped positioning plate 62 and connect to the fourth bracket 4.

[0023] In this invention, the installation position of the photovoltaic module in the slope formed by the first support 1 or the second support 2 is fixed by the limiting block 6 to prevent the photovoltaic module from moving downward.

[0024] Specifically, refer to Figure 2 As shown, the limiting body 61 of the limiting block 6 is used to connect with the frame of the photovoltaic module ( Figure 2 The limiting block 6 is positioned by abutting against the frame (indicated by the "frame"), and then the L-shaped positioning plate 62 is used to fix the position of the limiting block 6. Finally, the connecting piece 63 is used to fix it to the fourth bracket 4, or, if necessary, it can also be fixed to the first bracket 1 or the second bracket 2. The limiting body 61 can be a cuboid or a strip structure. Alternatively, a gasket can be placed at the contact point with the photovoltaic module to protect the aluminum frame of the photovoltaic module from damage. Furthermore, the connecting piece 63 used to connect to the fourth bracket 4, the first bracket 1, or the second bracket 2 can be a bolt or other pin-like structure; this embodiment does not impose specific limitations on this.

[0025] It should be noted that in this utility model, the bottom end of the aforementioned third bracket 3 is fitted with a base 31. The base 31 includes a through hole and / or a positioning pin. The upper end of the base 31 is used to fit with the third bracket 3, and its lower end is used to connect with a fixed structure on the ground. The connection with the ground can be made by bolts, or by using positioning pins simultaneously or alone. The positioning pin refers to the positioning pin being directly driven into the fixed structure on the ground using a hammer. The fixed structure on the ground can be a cement block with a nested nut, or other structures into which the positioning pin can be inserted. This embodiment does not impose specific limitations on this.

[0026] In some embodiments, the present invention further includes a cover plate 7, the cover plate 7 having an arc-shaped cross-section, used to connect with the top end of the mounting portion, and its arc surface facing the mounting portion.

[0027] like Figure 3 As shown, the cover plate 7 with an arc-shaped cross-section is installed at the hinge point between the first bracket 1 and the second bracket 2, i.e., at the top of the mounting part, to prevent wind and sand or rainwater from entering the hinged structure and affecting its normal use or service life. The arc-shaped structure has a guiding effect, allowing rainwater to flow down and not remain on its surface. In addition, the arc-shaped structure can also reduce the possibility of wind and sand accumulating on the cover plate 7.

[0028] The aforementioned limiting lock 5 used to adjust the distance between the first bracket 1 and the third bracket 3, or to adjust the distance between the second bracket 2 and the third bracket 3, includes: a sleeve 51 and a pair of latches. The two latches are screwed to both ends of the sleeve 51. The sleeve 51 is rotated clockwise to bring the two latches closer to each other. The other ends of the two latches are inserted into the first bracket 1 and the third bracket 3 respectively, or into the second bracket 2 and the third bracket 3 respectively.

[0029] The working logic of the limit lock 5 is as follows: the limit lock 5 is set with a sleeve 51. Rotating the sleeve 51 in the forward direction will bring the two latches at both ends closer to each other, that is, shorten the straight distance between the first bracket 1 and the third bracket 3, or shorten the straight distance between the second bracket 2 and the third bracket 3; conversely, rotating the sleeve 51 in the reverse direction will make the two latches at both ends move away from each other, that is, push the first bracket 1 and the third bracket 3 apart, or push the second bracket 2 and the third bracket 3 apart.

[0030] Specifically, the sleeve 51 has internal threads at both ends, and the area where the latch connects to the sleeve 51 has corresponding external threads. The direction of the threads is set according to the rotation logic. In this embodiment, there is no specific restriction on the direction of the threads. In addition, for the aforementioned forward rotation of the sleeve 51 to bring the two latches closer to each other and reverse rotation to move them away from each other, in actual design, the logic can also be set to the opposite of this logic, that is, reverse rotation of the sleeve 51 to bring the two latches closer to each other and reverse rotation to move them away from each other.

[0031] It should be noted that the latch is connected to the first bracket 1, the second bracket 2, or the third bracket by means of a pin hole on its end.

[0032] Finally, the bidirectional photovoltaic module mounting bracket provided by this utility model optimizes the structure of existing photovoltaic module mounting brackets, which not only increases the number of photovoltaic modules that can be installed, but also facilitates the installation and disassembly of the modules. In addition, the entire mounting bracket has a simple structure, which effectively improves the practicality of the photovoltaic module mounting bracket.

[0033] The above embodiments merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
