[0002] Solar photovoltaic (PV) mounting brackets are specialized supports designed for placing, installing, and securing solar panels in a solar photovoltaic power generation system. Common materials include aluminum alloy, carbon steel, and stainless steel. As a solar PV mounting bracket manufacturer, we primarily use aluminum alloy as the material for our brackets.

[0003] Domestic utility model patent application number 202321144040.4 discloses an electrically controlled, fixed, adjustable tilt photovoltaic bracket, including a mounting frame. Multiple photovoltaic panels are mounted on the upper side of the mounting frame, and multiple support adjustment devices are connected to the lower side of the mounting frame. Each support adjustment device includes a support column, a support frame connected to the upper side of the support column, and the upper side of the support frame connected to the mounting frame. A cylinder is connected to the right side of the support frame, and the telescopic end of the cylinder is connected to the lower side of the mounting frame. Two support rods are connected to the right side of the support frame, and multiple arc-shaped plates are connected to the lower side of the mounting frame. Auxiliary limiting plates are connected to the outer sides of the two sets of support rods. This novel solution, by setting up support adjustment devices, can simultaneously support the mounting frame and photovoltaic panels while adjusting their angle. After angle adjustment, it can still provide auxiliary support and locking, improving the stability and wind resistance of the device. The aforementioned utility model uses the telescopic end of a cylinder to extend and retract one end of the photovoltaic panel to achieve the angle adjustment effect. However, this adjustment method requires high stability of the connection structure between the telescopic end of the cylinder and the photovoltaic panel.

The installation department positions the photovoltaic panel to ensure the stability of the photovoltaic panel installation. When disassembling the photovoltaic panel, the installation bolts can be removed directly to move the photovoltaic panels from both ends of the installation truss, achieving quick installation and disassembly of the photovoltaic panel.

Detailed Implementation

[0023] This specific embodiment is a photovoltaic bracket with a seasonally adjustable tilt angle.

[0024] The aforementioned utility model uses the telescopic end of a cylinder to extend and retract one end of the photovoltaic panel to achieve the angle adjustment effect. However, this adjustment method requires high stability of the connection structure between the telescopic end of the cylinder and the photovoltaic panel. If the photovoltaic panel needs to be disassembled, the connection structure between its bottom and the cylinder needs to be disassembled, which is cumbersome.

[0025] Its structural diagram is as follows Figures 1-4 As shown. A seasonally adjustable tilt photovoltaic support includes multiple sets of concrete blocks 1 directly installed on the ground at the installation location, a support 11 integrally cast and installed with the bottom of the concrete blocks 1, and multiple sets of photovoltaic panels 5. An adjustment frame 8 is installed on the top of the concrete blocks 1. A diagonal brace 12 is provided between the bottom of the support 11 and the top of the concrete blocks 1. Multiple positioning holes 13 are provided on the support 11. The adjustment frame 8 includes two sets of side frames 81, which are connected by fixing bolts through the connecting parts 82 on both sides. Fixing holes 83 are provided on the side frames 81. The adjustment frame 8 and the support 11 are fixedly installed by fixing bolts through the fixing holes 83 and the positioning holes 13. A side top plate 84 is welded to the top of the side frame 81. The installation position between the adjustment frame 8 and the support 11 can be adjusted according to the required installation position of the photovoltaic panels 5 and the known wind resistance, thereby adjusting the distance between the photovoltaic panels 5 and the concrete blocks 1 and adjusting the height of the photovoltaic panels 5.

[0026] A positioning block 7 is installed at the top of the adjusting frame 8. The positioning block 7 includes a flipping block 72, and a mounting truss 4 is installed at the top of the flipping block 72. Limiting frames 6 are snapped onto both sides of the photovoltaic panel 5 and fixed to the mounting truss 4 through the limiting frames 6. A docking frame 32 is installed on a set of adjusting frames 8 at the end. A bearing frame 31 is welded to one side of the docking frame 32, and a drive motor 2 is mounted on the top of the bearing frame 31. A reducer 3 is installed at the output end of the drive motor 2. A rotating shaft 33 is connected between the flipping blocks 72, and the output end of the reducer 3 is connected to the end of the rotating shaft 33. The positioning block 7 also includes an auxiliary frame 71 that cooperates with the flipping block 72. The rotating shaft 33 passes through the auxiliary frame 71 and is connected to the flipping block 72. A mounting top plate 73 is welded to the top of the flipping block 72. Several sets of base frame plates 43 are welded to the bottom of the mounting truss 4, and the mounting top plate 73 is docked with the base frame plate 43. Because the duration and intensity of sunshine vary significantly throughout the year, to maximize the power generation efficiency of the photovoltaic panel 5, the tilt angle of the photovoltaic panel 5 needs to be reduced in summer when the solar altitude angle is high, and increased in winter when the solar altitude angle is low to capture more low-angle sunlight. In spring and autumn, the tilt angle of the photovoltaic panel 5 needs to be close to the local latitude angle. The drive motor 2 drives the reducer 3 to rotate the rotating shaft 33, which in turn drives the flipping block 72 to rotate. The auxiliary frame 71 provides additional support, increasing the stability of the rotating shaft 33 and the flipping block 72, thus ensuring stable rotation of the photovoltaic panel 5 and achieving the function of adjusting the tilt angle to guarantee the maximum power generation efficiency of the photovoltaic panel 5. The reducer 3 is connected to the drive motor 2, converting the high speed of the drive motor 2 to a low speed at a lower cost, while simultaneously amplifying the output torque to achieve the appropriate speed for adjusting the tilt angle of the photovoltaic panel 5.

[0027] The limiting frame 6 includes a snap-fit ​​block 61 for fixing the photovoltaic panel 5. A mounting part 62 is provided on one side of the snap-fit ​​block 61, and a limiting part 63 is provided at the bottom of the snap-fit ​​block 61. A limiting groove 41 is opened inside the mounting truss 4, and the limiting part 63 snaps and positions itself inside the limiting groove 41. The limiting part 63 is snapped into the mounting truss 4 from both ends, so that the snap-fit ​​block 61 is installed on the top of the mounting truss 4. This first determines the approximate position of the photovoltaic panel 5, ensuring the stability of the connection between the mounting truss 4 and the limiting frame 6. Multiple sets of mounting holes 42 are opened on both sides of the base plate 43 at the bottom of the mounting truss 4. The mounting part 62 and the mounting truss 4 are fixedly installed by mounting bolts 64 passing through the mounting part 62 and the mounting holes 42. The mounting part 62 positions the photovoltaic panel 5 precisely, ensuring the stability of the photovoltaic panel 5 installation. When disassembling the photovoltaic panel 5, the mounting bolts 64 can be removed directly, allowing the photovoltaic panels 5 to be moved out from both ends of the mounting truss 4 in groups, achieving quick installation and removal of the photovoltaic panel 5. The other end of the rotating shaft 33 is fitted with a bearing seat that is fixedly mounted on the top of the auxiliary frame 71. The connecting frame 32 and the two sets of side frames 81 are fixedly mounted by fixing bolts passing through the connecting frame 32 and the fixing holes 83. This ensures the stability of the drive motor 2 and the reducer 3 during use.

[0028] First, the snap-fit ​​blocks 61 are installed on both sides of the photovoltaic panel 5. The limiting parts 63 are snapped into the top of the mounting truss 4 from both ends. The approximate position of the photovoltaic panel 5 is determined first, and the mounting bolts 64 are used to fix the photovoltaic panel 5 in place through the mounting parts 62 and mounting holes 42 to ensure the stability of the photovoltaic panel 5. Then, the bottom frame plate 43 of the mounting truss 4 is installed by connecting it to the mounting top plate 73. The side frames 81 are connected by fixing bolts through the connecting parts 82 on both sides. The adjusting frame 8 and the bracket 11 are fixed by fixing bolts. The holes 83 and 13 are fixedly installed. The installation position between the adjustment frame 8 and the bracket 11 can be adjusted according to the required installation position of the photovoltaic panel 5 and the known wind resistance, thereby adjusting the distance between the photovoltaic panel 5 and the concrete block 1. Finally, the auxiliary frame 71 is connected to the side top plate 84 for installation. During use, depending on the different directions of sunlight caused by the season, the drive motor 2 drives the reducer 3 to rotate the rotating shaft 33, so that the rotating shaft 33 drives the flipping block 72 to rotate, thereby adjusting the tilt angle of the photovoltaic panel 5 and ensuring the maximum power generation efficiency of the photovoltaic panel 5.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
