Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation technology, and more specifically, it relates to a mounting bracket for photovoltaic panels. Background Technology

[0002] With the popularization of photovoltaic power generation technology, photovoltaic panel mounting racks, as key components of the support system, are widely used in rooftop, ground-mounted power stations, and building-integrated photovoltaics (BIPV). Traditional mounting racks need to meet requirements such as wind load resistance, corrosion resistance, and rapid installation. At the same time, fixed, adjustable tilt, and tracking structures have been developed to suit different terrains (such as pitched roofs, deserts, and water surfaces). In recent years, with the trend of photovoltaic modules becoming larger and lighter, mounting racks need to balance higher structural strength and portability, and the requirements for installation efficiency and cost control are becoming increasingly stringent.

[0003] In existing technologies, photovoltaic panels are generally fixed to mounting brackets using bolts. While this method is simple and low-cost, uneven or excessive tightening of the bolts can cause micro-cracks in the photovoltaic panel glass or frame. Over time, this can lead to hidden cracks, reducing power generation efficiency and even causing module failure. Furthermore, installing solar photovoltaic panels on the brackets often requires hoisting. During hoisting, the panels are susceptible to swaying due to wind, and manual adjustment is time-consuming, impacting installation efficiency. Additionally, the inconvenience of adjusting the panel's support angle reduces its practicality. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a mounting bracket for photovoltaic panels, which has the following advantages:

[0017] 1. The stability of the support structure is improved by setting ground piles. The rotatable connection between the support rod and the fixed rod makes it easy to support one end of the support frame on the ground to install solar panels, which improves the convenience of installation. The rotating frame makes it easy to adjust the support angle of the solar panels, thereby improving the power generation efficiency of the solar panels.

[0018] 2. By rotating the limiting screw, the moving block is driven to move in the moving groove. The limiting rod on the moving block is inserted into the limiting hole to fix the position of the rotating frame and fix the rotation direction of the solar panel.

[0019] 3. The engagement of the internal and external threaded sleeves facilitates the adjustment of the snap-fit ​​sleeve position. The snap-fit ​​sleeve presses against the snap-fit ​​block, causing the snap-fit ​​block to be pressed into the snap-fit ​​ring groove, thereby fixing the relative position of the mounting sleeve and the mounting rod, and then installing the solar panel. This improves the thread engagement force of the internal and external threaded sleeves, thus improving the installation stability. Attached Figure Description

[0029] Please see Figures 1-5 A photovoltaic panel mounting bracket includes a support 1, which includes a fixed rod 2. A fixed frame 3 is mounted on the fixed rod 2. A support rod 4 is rotatably mounted on the fixed frame 3 via anchor bolts. A fixing bolt 5 is provided between the fixed frame 3 and the support rod 4. A support frame 6 is mounted on the support rod 4. A rotating frame 7 is rotatably mounted on the support frame 6 via anchor bolts. An mounting device and a solar panel 8 are mounted on the rotating frame 7. A limiting device is provided between the rotating frame 7 and the support frame 6. The mounting device includes a mounting sleeve 9, which is mounted on the rotating frame 7. An mounting rod 10 is provided at the bottom of the solar panel 8. The mounting sleeve 9 has a circumferential locking mechanism. The mounting sleeve 10 has a snap-fit ​​rod 12 rotatably mounted on the snap-fit ​​groove 11 via a rotating shaft. The mounting rod 10 has a snap-fit ​​ring groove 13 that mates with the snap-fit ​​rod 12. The mounting sleeve 9 has a snap-fit ​​sleeve 14 on its outer side. The snap-fit ​​sleeve 14 has a compression groove 15 that mates with the snap-fit ​​rod 12. A compression block 16 is located above the compression groove 15. An internally threaded sleeve 17 is rotatably mounted on the outer side of the mounting sleeve 9. An externally threaded sleeve 18 is fixedly mounted at one end of the snap-fit ​​sleeve 14. The mounting sleeve 9 has a compression plate 19. A compression spring 20 is located between the compression plate 19 and the snap-fit ​​sleeve 14. A ground stake 28 is located at the bottom of the bracket 1.

[0030] In this embodiment, the support stability of the bracket 1 is improved by the ground piles 28. When installing the solar panel 8, the fixing bolts 5 are removed, the support rod 4 is laid down around the fixing frame 3, and then the solar panel 8 is installed on the rotating frame 7. The mounting rod 10 of the solar panel 8 is inserted into the mounting sleeve 9. Then, the internal threaded sleeve 17 is rotated, which drives the external threaded sleeve 18 and the snap-fit ​​sleeve 14 to move upward. The snap-fit ​​sleeve 14 presses the snap-fit ​​rod 12 upward through the compression groove 15, so that the other end of the snap-fit ​​rod 12 extends into the snap-fit ​​ring groove 13, thereby fixing the relative position of the mounting rod 10 and the mounting sleeve 9. When the snap-fit ​​sleeve 14 moves upward, it compresses the spring 20, which increases the thread engagement force between the inner thread sleeve 17 and the outer thread sleeve 18, thereby improving the positional stability of the snap-fit ​​sleeve 14 and the snap-fit ​​rod 12. The position of the support rod 4 is flipped, and the support rod 4 and the fixing frame 3 are supported and fixed by the cooperation of the fixing bolt 5 and the nut. When it is necessary to disassemble and maintain the solar panel 8, the inner thread sleeve 17 is reversed, which can drive the outer thread sleeve 18 and the snap-fit ​​sleeve 14 to move downward. Through the squeezing block 16, the snap-fit ​​rod 12 is flipped and leaves the snap-fit ​​ring groove 13, which facilitates the disassembly of the mounting rod 10 and the solar panel 8.

[0031] Please see Figure 5As one embodiment of the limiting device: the limiting device includes a limiting sleeve 21, a limiting rod 22 on the limiting sleeve 21, a limiting groove 23 on the rotating frame 7 that cooperates with the limiting sleeve 21, and a limiting hole 24 that cooperates with the limiting rod 22. Multiple limiting holes 24 are provided. The limiting sleeve 21 is provided with a moving groove 25. A moving block 26 is slidably provided in the moving groove 25. The limiting rod 22 is fixedly provided on the moving block 26. A limiting screw 27 is rotatably provided in the limiting sleeve 21. The two ends of the limiting screw 27 are provided with threads that are opposite to those of the symmetrical screw. The limiting screw 27 is threadedly connected to the moving block 26.

[0032] More specifically, based on the terrain, the support angle of the solar panel 8 is adjusted, the limiting screw 27 is rotated, the limiting screw 27 rotates, causing the moving block 26 to move in the opposite direction, so that the moving block 26 moves along the moving groove 25, the limiting rod 22 disengages from the limiting hole 24, the rotating frame 7 is rotated, the limiting sleeve 21 moves in the limiting groove 23, after the adjustment is completed, the limiting screw 27 is rotated, the limiting screw 27 causes the moving block 26 to move in the opposite direction, causing the limiting rod 22 to be inserted into the limiting hole 24, fixing the relative position of the rotating frame 7 and the support frame 6, thereby completing the adjustment of the direction of the solar panel 8.

[0033] In summary, during use or operation of the overall equipment: the ground piles 28 improve the support stability of the bracket 1; when installing the solar panel 8, the fixing bolts 5 are removed, the support rod 4 is laid down around the fixing frame 3, and then the solar panel 8 is installed on the rotating frame 7. The mounting rod 10 of the solar panel 8 is inserted into the mounting sleeve 9, and then the internal threaded sleeve 17 is rotated. The internal threaded sleeve 17 drives the external threaded sleeve 18 and the snap-fit ​​sleeve 14 to move upward. The snap-fit ​​sleeve 14 presses the snap-fit ​​rod 12 upward through the compression groove 15, so that the other end of the snap-fit ​​rod 12 extends into the snap-fit ​​ring groove 13, thereby fixing the mounting rod 10 and the mounting sleeve 9. In terms of relative position, when the snap-fit ​​sleeve 14 moves upward, it compresses the spring 20, which increases the thread engagement force between the internal thread sleeve 17 and the external thread sleeve 18, thereby improving the positional stability of the snap-fit ​​sleeve 14 and the snap-fit ​​rod 12. It flips the position of the support rod 4, and through the cooperation of the fixing bolt 5 and the nut, it supports and fixes the support rod 4 and the fixing frame 3. When it is necessary to disassemble and maintain the solar panel 8, flipping the internal thread sleeve 17 will drive the external thread sleeve 18 and the snap-fit ​​sleeve 14 to move downward. Through the squeezing block 16, it will drive the snap-fit ​​rod 12 to flip and leave the snap-fit ​​ring groove 13, which will facilitate the disassembly of the mounting rod 10 and the solar panel 8.

[0034] According to the terrain, adjust the support angle of the solar panel 8, rotate the limiting screw 27, the limiting screw 27 rotates and drives the moving block 26 to move in the opposite direction, so that the moving block 26 moves along the moving groove 25, the limiting rod 22 disengages from the limiting hole 24, rotate the rotating frame 7, the limiting sleeve 21 moves in the limiting groove 23, after the adjustment is completed, rotate the limiting screw 27, the limiting screw 27 drives the moving block 26 to move in the opposite direction, and drives the limiting rod 22 to insert into the limiting hole 24, fix the relative position of the rotating frame 7 and the support frame 6, and thus complete the adjustment of the direction of the solar panel 8.
