Description

Technical Field

[0001] This utility model relates to the field of photovoltaic system installation technology, and in particular to a photovoltaic module mounting bracket. Background Technology

[0002] With the increasing global demand for clean energy, solar photovoltaic (PV) power generation technology has been widely adopted. As the core component of a PV system, the stability, reliability, and light-gathering efficiency of PV modules directly affect the overall energy output of the system. Currently, PV modules are typically fixed using dedicated mounting frames to avoid occupying excessive ground space and ensure safety when installed at high locations.

[0003] In the prior art, CN219627613U discloses a solar panel bracket that is easy to assemble. It forms a support assembly by combining left and right branch plates with docking clips, and uses a slot and clip structure to connect with other rods, which is designed to facilitate transport and installation at heights.

[0004] Although existing modular mounting racks have solved the basic requirements for high-level installation to some extent, they still have the following defects: (1) High assembly cost and poor adaptability; most existing racks are composed of a large number of loose parts, requiring a lot of manpower and time to assemble the parts; and are prone to affecting the overall stability due to human error; at the same time, photovoltaic modules have various specifications and sizes (such as 166mm, 182mm, 210mm, etc.); although some structural dimensions are adjustable, the adjustment process often requires disassembly and reassembly, which is complicated and difficult to quickly adapt to the diverse photovoltaic module specifications on the market. (2) Fixed structure and insufficient flexibility; once the traditional mounting rack is assembled, its tilt angle and support span are difficult to adjust. This makes it impossible to optimize the optimal light tilt angle according to different geographical latitudes, and also impossible to adapt to the solar altitude angle that changes over time, thus limiting the power generation efficiency of solar panels. (3) Insufficient space adaptability; the fixed structure of the mounting rack cannot flexibly switch between storage and working states; large mounting racks occupy too much space during transportation and storage, while small mounting racks may not be able to provide sufficient support stability for photovoltaic modules, resulting in serious structural limitations.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0026] This utility model provides a photovoltaic module mounting bracket, such as Figure 1-3 As shown, it includes: Base 1 is a load-bearing base, usually in the form of a square frame structure. Base 1 is connected to the ground and is used to provide support for the entire mounting frame and photovoltaic modules.

[0027] In one alternative approach, multiple ground piles 2 are equidistantly distributed around the bottom end of the base 1. The ground piles 2 can be fixed to the ground foundation by pre-embedding in concrete or by expansion bolts, further ensuring the overall stability of the base 1; The movable assembly includes a movable support 3, an elevated frame 5, and a lifting frame 6. At least two movable supports 3 are provided and are movably mounted on the base 1. The elevated frame 5 is mounted on the movable support 3 at the rear position to provide a higher rear support point. The lifting frame 6 is mounted on the movable support 3 at the front position and its initial height is lower than that of the elevated frame 5 to provide an adjustable front support point.

[0028] In one alternative configuration, a storage cavity adapted to the movable bracket 3 is provided at the corner of the base 1, and the movable bracket 3 can slide radially along the storage cavity.

[0029] In one alternative embodiment, the elevated structure 5 includes two tensioning struts 51 whose lower ends are movably connected to the movable support 3, and a support base 53 connected to the top of the two tensioning struts 51 for supporting the first crossbeam 7. This tensioning structure allows the elevated structure 5 to be folded for easy transportation and storage.

[0030] Preferably, a combination cover 52 is fixedly fitted to the top of the tensioning support rod 51, and a support base 53 is connected between the two combination covers 52; this structure can enhance the connection stability at the top and prevent the support base 53 from shifting under force.

[0031] More preferably, a first locking hole 54 and a second locking hole 55 are provided at the connection between the tensioning support rod 51 and the movable bracket 3, and / or at the connection between the support base 53 and the first crossbeam 7. By inserting a locking pin into the locking hole or screwing in a bolt, the tensioning support rod 51 and the movable bracket 3 can be quickly fixed, or the support base 53 and the first crossbeam 7 can be firmly connected, thereby stably locking the elevated frame 5 in the working state.

[0032] In one alternative embodiment, the lifting frame 6 includes a guide tube 61 fixed to the movable support 3, a lifting rod 62 slidably inserted in the guide tube 61 for supporting the front end of the first crossbeam 7, and a linkage adjustment mechanism for synchronously adjusting and locking the two lifting rods 62.

[0033] Preferably, the linkage adjustment mechanism includes sleeve plates 63 disposed on two guide tubes 61, an elastic telescopic plate 64 movably connected between the two sleeve plates 63, a guide frame 65 integrally connected to the middle of the elastic telescopic plate 64, and a limiting strut 66 disposed on the guide frame 65 for simultaneously pulling and locking the two lifting rods 62. This mechanism can realize synchronous lifting and precise locking of the front support point, making the tilt angle adjustment of the installation plane simple and accurate.

[0034] The first crossbeam 7 has its two ends connected to the top of the elevated frame 5 and the lifting frame 6 on the same side, respectively. By combining the fixed height of the elevated frame 5 with the adjustable height of the lifting frame 6, multiple first crossbeams 7 together form an installation plane with an adjustable tilt angle.

[0035] The second crossbeam 8 is installed between different first crossbeams 7, and together with the first crossbeams 7, it forms a stable load-bearing grid, enhancing the support capacity for photovoltaic modules.

[0036] Fixture 9; Multiple fixtures 9 are disposed on the second crossbeam 8 for final fixing of the photovoltaic module 100. The fixtures 9 can be conventional fixing elements in the art, such as clips or clamps, to accommodate photovoltaic modules of different specifications.

[0037] In an alternative embodiment, the mounting bracket further includes a telescopic assembly 4, which includes a drive component and a transmission mechanism connected between the drive component and the movable bracket 3, for driving all movable brackets 3 to move. This allows for the synchronous adjustment of multiple sets of movable brackets 3 through a single operation, greatly improving the adaptability of the mounting bracket width.

[0038] Preferably, the driving component is a rhomboid turntable 41 rotatably mounted at the center of the base 1. This rhomboid structure can efficiently decompose a single rotational motion into linear driving forces in four directions, ensuring synchronous adjustment of the movable support 3.

[0039] Furthermore, the transmission mechanism includes a guide hole 42 at the bottom of the base 1, a movable slider 43 slidably disposed within the guide hole 42 and fixedly connected to the movable bracket 3, and a right-angle pull rod 44, one end of which is eccentrically connected to the rhomboid turntable 41 and the other end of which is movably connected to the movable slider 43. When the rhomboid turntable 41 is rotated, the right-angle pull rod 44 pulls the movable slider 43 and the movable bracket 3 to slide precisely radially along the guide hole 42, thereby adjusting the width of the mounting bracket.

[0040] The photovoltaic module mounting bracket of this utility model is described below with reference to a specific embodiment of the utility model, and further explained and illustrated. It is worth understanding that the following description is only an exemplary illustration and not a specific limitation of this utility model.

[0041] Example 1

[0042] like Figure 1-2As shown, the photovoltaic mounting bracket includes a load-bearing base 1, with four ground stakes 2 fixedly connected to the bottom of the load-bearing base 1. The four ground stakes 2 are equidistantly distributed around the perimeter. Storage cavities are provided at the four corners of the load-bearing base 1. Four movable brackets 3 are movably installed in the storage cavities. Each of the two movable brackets 3 at the rear position has an elevated frame 5. Each of the two movable brackets 3 at the front position has a lifting frame 6 that is lower than the elevated frame 5. Two first crossbeams 7, which are inclined and parallel to each other, are connected between the elevated frames 5 and the lifting frames 6 on the left and right sides. Two second crossbeams 8 are connected between the two first crossbeams 7. Each of the two second crossbeams 8 is provided with a fastener 9 for fixing the photovoltaic modules. The fastener consists of four clips, which are spaced apart on the second crossbeams. The distance between the clips is suitable for photovoltaic modules of different specifications.

[0043] The movable bracket 3 slides within the storage cavity, allowing adjustment of the distance between the elevated frame 5 and the lifting frame 6 connected to the movable bracket 3. This enables the mounting frame to be adapted to the installation of photovoltaic modules of different specifications.

[0044] like Figure 3 As shown, the elevated frame 5 includes two tensioning support rods 51 connected to the movable support 3 by pins. Each tensioning support rod 51 has a fixed cap 52 at its top. Both caps 52 are connected to a support seat 53 for supporting the rear end of the first crossbeam 7. The tensioning support rods 51 and caps 52 have corresponding first locking holes 54, and the support seat 53 and the first crossbeam 7 have corresponding second locking holes 55. The tensioning support rods 51 can rotate around their connection point with the movable support 3 to adjust the height of the elevated frame 5 or fold it for storage. After adjustment, the angle of the tensioning support rod 51 can be fixed by inserting a locking pin into the first locking hole 54; and the connection between the support seat 53 and the first crossbeam 7 can be fixed by screwing a bolt into the second locking hole 55.

[0045] like Figure 3 As shown, the lifting frame 6 includes a guide tube 61 fixedly connected to the movable support 3. A lifting rod 62 for supporting the front end of the first crossbeam 7 is slidably fitted in the guide tube 61. A sleeve plate 63 is welded on both guide tubes 61. An elastic telescopic plate 64 is movably connected between the two sleeve plates 63. A guide frame 65 is integrally connected to the middle of the elastic telescopic plate 64. A limiting strut 66 for pulling and fixing the two lifting rods 62 is provided on the guide frame 65. A third locking hole 67 is opened in the first crossbeam 7 corresponding to the lifting rod 62.

[0046] When adjusting the height of the lifting frame 6, loosen the bolts connecting the two ends of the limiting truss 66 to the lifting rods 62, and push the limiting truss 66 to drive the two lifting rods 62 to slide up and down synchronously along the guide tube 61, thereby adjusting the height difference between the elevated frame 5 and the lifting frame 6. After adjustment, tighten the bolts connecting the limiting truss 66 and the lifting rods 62, and simultaneously screw bolts into the third locking hole 67 to fix the lifting rods 62 and the first crossbeam 7, completing the height locking. The elastic telescopic plate 64 can extend and retract synchronously with the movement of the lifting rods 62 to ensure the stability of the linkage adjustment mechanism.

[0047] Adjusting the height of the lifting frame 6 allows for adjusting the tilt angle of the installation plane formed by the elevated frame 5 and the lifting frame 6, enabling the photovoltaic modules to maximize power generation under different lighting conditions. For example, in summer, the lifting frame 6 can be lowered to create a larger angle between the installation plane and the ground, allowing the photovoltaic modules to absorb more sunlight; in winter, the lifting frame 6 can be raised to create a smaller angle between the installation plane and the ground, allowing the photovoltaic modules to absorb more sunlight.

[0048] By adjusting the height difference between the elevated frame 5 and the lifting frame 6, the first crossbeam 7 can be configured with mounting planes at different tilt angles, thereby maximizing the power generation of the photovoltaic module 100 under different lighting conditions. For example, in the Northern Hemisphere, where the solar altitude angle is high in summer, the lifting frame 6 can be lowered to reduce the tilt angle between the mounting plane and the ground, preventing excessive exposure of the module to sunlight and ensuring efficient light reception. In winter, where the solar altitude angle is low, the lifting frame 6 can be raised to increase the tilt angle between the mounting plane and the ground, allowing for greater sunlight reception.

[0049] Example 2

[0050] like Figure 4 As shown, the mounting frame also includes a telescopic assembly 4, which includes a rhomboid turntable 41 rotatably mounted at the center of the load-bearing base 1. The bottom end of the load-bearing base 1 has a guide elongated hole 42 that connects to the storage cavity. A movable slider 43, which is fixedly connected to the movable bracket 3 and is movably pulled by the rhomboid turntable 41, is slidably mounted in the guide elongated hole 42. A right-angle pull rod 44, which is eccentrically set and movably connected to the movable slider 43, is pinned to the rhomboid turntable 41.

[0051] When adjusting the spacing of the movable bracket 3, rotate the rhomboid turntable 41. The rhomboid turntable 41 drives the movable slider 43 to slide along the guide hole 42 through the right-angle pull rod 44. The movable slider 43 further pulls the movable bracket 3 to move synchronously in the storage cavity, thereby adjusting the spacing between the elevated frame 5 and the lifting frame 6 connected to the movable bracket 3 to adapt to photovoltaic modules of different widths.
