Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, specifically a steel structure photovoltaic support. Background Technology

[0002] Photovoltaic (PV) mounting systems are essential infrastructure for installing photovoltaic (PV) modules. Their main function is to fix and support the PV modules and adjust their angle and orientation to maximize sunlight reception. PV mounting systems can be classified in various ways depending on the classification method used.

[0003] Conventional photovoltaic brackets are equipped with two sets of brackets, front and rear. During adjustment, multiple workers are needed to support and adjust the spacing, height and verticality of the front and rear bracket bodies respectively.

[0004] However, conventional adjustment methods can easily lead to misalignment of the heights of the two sets of supports, resulting in installation errors. This requires frequent adjustments and measurements, which not only wastes manpower and resources but also affects the quality of the installation process. Therefore, it is necessary to provide a steel structure photovoltaic support to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a steel structure photovoltaic support that eliminates the need for multi-frequency adjustment and measurement of the front and rear sets of supports, saving manpower and resources, and ensuring the quality of the installation process.

[0007] The technical solution adopted by this application to solve its technical problem is: a steel structure photovoltaic support bracket, comprising:

[0008] The base frame has vertical bars installed on both sides of its upper end, and horizontal bars are installed at the upper ends of the vertical bars. A mounting plate is provided at the upper end of the horizontal bars, and the mounting plate is used to install photovoltaic panels.

[0009] A fixed base is installed at the upper end of the crossbar, and rotating plates are provided on both sides of the fixed base. The rotating plates are installed at the lower end of the mounting plate, and a drive rod is installed on the rotating plate. The two ends of the drive rod protrude from the mounting plate, and the drive rod is rotatably connected to the fixed base.

[0010] An adjustment mechanism is provided at both ends of the drive rod. The adjustment mechanism has a ratchet mounted on the outer end of the drive rod, and a handle is mounted on the outer axis of the ratchet.

[0011] Furthermore, a fixing block is fixedly installed on one side of the upper end of the crossbar, and a threaded hole is opened on the fixing block. A mating hole is opened on the ratchet, and the mating hole and the threaded hole correspond to each other. A second bolt is provided in the mating hole, and the second bolt is threadedly connected to the threaded hole.

[0012] Furthermore, a support mechanism is provided on one side of the ratchet. The support mechanism has a support block fixedly installed on the upper end of the crossbar. Two sets of opposing fixing frames are fixedly installed on the upper end of the support block. The upper ends of the fixing frames are rotatably connected with locking teeth, which are oriented towards the ratchet.

[0013] Furthermore, a spring is fixedly installed between the locking teeth and the support block, and a horizontal mounting groove is fixedly installed at the upper end of the fixing frame. The horizontal mounting groove has an opening, and a baffle is fitted inside the horizontal mounting groove.

[0014] Furthermore, a threaded groove is provided through the upper end face of the horizontal mounting groove, and a first bolt is threadedly connected inside the threaded groove.

[0015] Furthermore, a vertical mounting groove is fixedly installed on one side of the support block, and the vertical mounting groove cooperates with the baffle.

[0016] Furthermore, the protruding end of the drive rod is rotatably connected to a support seat, which is fixedly installed on the upper end of the crossbar.

[0017] The beneficial effects of this application are as follows: The steel structure photovoltaic bracket provided by this application is equipped with an adjustment mechanism. When adjusting the angle of the photovoltaic panel on the mounting plate, the second bolt is first unscrewed and removed. Then, the ratchet and drive rod are manually rotated by the handle, thereby rotating the mounting plate and completing the angle adjustment of the photovoltaic panel. Therefore, it is not necessary to perform multi-frequency adjustment and measurement on the front and rear brackets, saving manpower and resources, and ensuring the quality of the installation process.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figures 1-2 As shown, this application provides a steel structure photovoltaic support, including a base frame 1. Vertical rods 11 are fixedly installed on both sides of the upper end of the base frame 1. A horizontal rod 12 is fixedly installed on the upper end of the vertical rod 11. An installation plate 13 is provided on the upper end of the horizontal rod 12. The installation plate 13 is used to install photovoltaic panels.

[0033] To allow the angle of the mounting plate 13 to be adjustable, multiple sets of fixing seats 15 are fixedly installed on the upper end of the crossbar 12. Rotating plates 14 are provided on both sides of the fixing seats 15. The rotating plates 14 are fixedly installed on the lower end of the mounting plate 13. At the same time, a drive rod 16 is fixedly installed on the rotating plate 14. The two ends of the drive rod 16 protrude from the mounting plate 13. The drive rod 16 is rotatably connected to the fixing seat 15. Therefore, rotating the drive rod 16 can cause the rotating plate 14 to rotate along the fixing seat 15.

[0034] like Figures 3-4 As shown, a support base 17 is rotatably connected to the protruding end of the drive rod 16. This support base 17 is fixedly installed on the upper end of the crossbar 12. Simultaneously, adjustment mechanisms 2 are provided at both ends of the drive rod 16, allowing for convenient adjustment of the drive rod 16. These two sets of adjustment mechanisms 2 are arranged opposite each other and have identical structures. The following description uses one set as an example. Specifically:

[0035] The adjustment mechanism 2 has a ratchet 21 fixedly installed on the outer end of the drive rod 16. A handle 22 is fixedly installed on the outer axis of the ratchet 21. The handle 22 can drive the ratchet 21 and the drive rod 16 to rotate simultaneously. In order to fix the drive rod 16, a fixing block 23 is fixedly installed on the side of the upper end of the crossbar 12 away from the support seat 17. The fixing block 23 has a threaded hole 24.

[0036] Meanwhile, multiple sets of mating holes 26 are provided on the ratchet 21. The mating holes 26 are arranged in a circle with the axis of the ratchet 21 as the center. The mating holes 26 correspond to the threaded holes 24. In this application, a second bolt 25 is provided in one of the mating holes 26. The second bolt 25 is threadedly connected to the threaded hole 24. Therefore, when the second bolt 25 is inserted into the mating hole 26 and screwed into the threaded hole 24, the ratchet 21 will be fixed, thereby fixing the drive rod 16 and the mounting plate 13 to prevent the photovoltaic panel from shaking during use.

[0037] Therefore, when adjusting the angle of the photovoltaic panel on the mounting plate 13, the second bolt 25 is first unscrewed and removed. Then, the ratchet 21 and drive rod 16 are manually rotated by the handle 22, thereby rotating the mounting plate 13 and completing the angle adjustment of the photovoltaic panel. Thus, it is not necessary to perform multi-frequency adjustment and measurement on the front and rear brackets, saving manpower and resources and ensuring the quality of the installation process.

[0038] To prevent the photovoltaic panel on the mounting plate 13 from being damaged by rapid downward movement due to gravity when the drive lever 16 is adjusted and may slip out of hand or cause other accidents, a support mechanism 3 is provided on one side of the ratchet 21. The support mechanism 3 has a support block 31 fixedly installed on the upper end of the crossbar 12. Two sets of opposing fixing frames 32 are fixedly installed on the upper end of the support block 31. The upper ends of the fixing frames 32 are rotatably connected by a locking tooth 33. The locking tooth 33 is set towards the ratchet 21. Under normal conditions, the locking tooth 33 is locked between the ratchet teeth of the ratchet 21.

[0039] Meanwhile, a spring 34 is fixedly installed between the cleat 33 and the support block 31, and the cleat 33 is supported by the spring 34. A horizontal mounting groove 35 is fixedly installed at the upper end of the fixing frame 32. The horizontal mounting groove 35 has an opening facing the ratchet 21. A baffle 36 is installed in the horizontal mounting groove 35.

[0040] In order to fix the baffle 36, a threaded groove 38 is provided through the upper end face of the horizontal mounting groove 35. The first bolt 39 is threadedly connected in the threaded groove 38. Therefore, tightening the first bolt 39 will fix the baffle 36 in the horizontal mounting groove 35.

[0041] In this application, a vertical mounting groove 37 is fixedly installed on one side of the support block 31. The vertical mounting groove 37 has an upward-facing opening and cooperates with the baffle 36.

[0042] It should be noted that in this application, the drive rod 16, mounting plate 13, horizontal bar 12, vertical bar 11, and base frame 1 are all steel structures.

[0043] Therefore, during the adjustment of the photovoltaic panel angle on the mounting plate 13, if it is necessary to rotate the drive rod 16 counterclockwise, specifically as follows: Figure 3 As shown, the baffle 36 is installed in the horizontal mounting groove 35 and fixed with the first bolt 39. Then the second bolt 25 is removed, and the ratchet 21 and the drive rod 16 are manually driven to rotate counterclockwise by the handle 22.

[0044] During the counterclockwise rotation of ratchet 21, its ratchet teeth will press the locking teeth 33 downward and compress the spring 34 until the locking teeth 33 reach the next ratchet tooth of ratchet 21. Then the spring 34 will return to its original position and lock ratchet 21. At this time, because the baffle 36 will block the locking teeth 33, ratchet 21 cannot rotate in the opposite direction.

[0045] After adjustment, insert the second bolt 25 into the mating hole 26 corresponding to the threaded hole 24, and then tighten it to fix the ratchet 21.

[0046] If it is necessary to rotate the drive lever 16 clockwise, the specific steps are as follows: Figure 5As shown, the baffle 36 is installed in the vertical mounting groove 37. The baffle 36 falls into the vertical mounting groove 37 due to gravity. Then the second bolt 25 is removed, and the ratchet 21 and the drive rod 16 are manually driven to rotate clockwise simultaneously by the handle 22.

[0047] During the clockwise rotation of ratchet 21, its ratchet teeth will push the locking teeth 33 upward and stretch the spring 34 until the locking teeth 33 reach the next ratchet tooth of ratchet 21. Then the spring 34 will return to its original position and lock ratchet 21. At this time, because the baffle 36 is located below the locking teeth 33, it will push the locking teeth 33 against it, so ratchet 21 cannot rotate in the opposite direction.

[0048] After adjustment, insert the second bolt 25 into the mating hole 26 corresponding to the threaded hole 24, and then tighten it to fix the ratchet 21, thus completing the adjustment operation. Therefore, if the drive rod 16 is released or other accidents occur during adjustment, the photovoltaic panel on the mounting plate 13 will not be damaged by rapidly falling in the opposite direction due to gravity when it rotates, thus improving the adjustment efficiency and ensuring safety during the adjustment process.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
