Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a photovoltaic support plate structure and a photovoltaic support. Background Technology

[0002] A photovoltaic (PV) bracket is a support structure used to install and fix solar photovoltaic (PV) modules (such as solar panels). The PV bracket support plate is an important component of the PV bracket system. It is mainly used to directly support and fix the solar PV modules (such as solar panels). It is located at the top of the bracket and the PV modules are firmly installed on the bracket structure by bolts or other connectors.

[0003] The patent with publication number CN214851036U discloses a photovoltaic support plate structure for installation and positioning on purlins to support photovoltaic modules. The support plate structure includes a main body and two side parts vertically arranged on both sides of the main body. The two side parts are respectively provided with slots at corresponding positions. When the support plate structure is installed and positioned on the purlins, it is secured to the purlins by the slots. This device can also enhance the structural strength and stability of the support plate structure and the entire system.

[0004] However, the aforementioned photovoltaic support plate structure still has the following problems in actual use:

[0005] The support plate is the connection between the photovoltaic panel and the photovoltaic bracket. Before installing the photovoltaic panel, the support plate needs to be installed on the crossbeam of the bracket. Currently, most of the methods are to pre-fix it by using the clips at the bottom of the support plate to clip onto the outside or inside sides of the bracket. After the photovoltaic panel is placed on top of the support plate, a long bolt is passed through the pressure plate, the support plate and the crossbeam and then tightened with a nut.

[0006] However, simply securing the tray to the crossbeam with two clips makes it easy for the tray to shift during the handling and installation of photovoltaic panels. This shifting of the tray can cause the through holes on the tray to align with the mounting holes on the crossbeam, increasing the difficulty of alignment later and reducing installation efficiency. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a photovoltaic support plate structure and a photovoltaic support, which can prevent the support plate body from moving on the crossbeam.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic support plate structure, comprising several plate bodies installed on a photovoltaic support, two parallel clamping plates fixedly connected to the bottom surface of the plate body, two parallel positioning plates fixedly connected to the upper surface of the plate body, a limiting tube fixedly connected to the middle of the plate body, two mounting holes through the lower end of the limiting tube, elastic sheets fixedly connected to the inner walls of the two mounting holes, a pressing component connected inside the limiting tube, and the upper end of the pressing component extending above the limiting tube and connected to the limiting component.

[0009] Furthermore, the limiting component includes a base plate and two L-shaped pressure blocks. The two sides of the upper surface of the base plate are fixedly connected to the lower ends of the two L-shaped pressure blocks respectively. An adjustment port is provided through the side of the two L-shaped pressure blocks near the base plate, and the upper end of the extrusion component is located in the adjustment port.

[0010] Furthermore, the extrusion assembly includes a locking knob, a threaded rod, and a truncated cone. The locking knob is located inside the adjustment port and is sleeved and threaded onto the outer wall of the threaded rod. The lower end of the threaded rod extends through to the bottom of the limiting tube and is fixedly connected to the upper end of the truncated cone.

[0011] Furthermore, the cone is narrower at the top and wider at the bottom, with the diameter of the wider end of the cone not exceeding the diameter of the outer ring of the limiting tube, and the diameter of the wider end of the cone not being less than the diameter of the inner ring of the limiting tube.

[0012] Furthermore, two openings are made through the bottom surface of the limiting tube.

[0013] A photovoltaic support bracket includes two rear columns, two front columns, two inclined beams, and two crossbeams. The photovoltaic support bracket also includes the aforementioned photovoltaic support bracket structure. Several mounting holes are provided through the bottom surface of each of the two crossbeams. Limiting tubes are slidably connected to the mounting holes of the crossbeams. Two clamping plates are slidably connected to the two sides of the crossbeams respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This type of photovoltaic bracket support structure and photovoltaic bracket, through the cooperation of the limiting tube and the crossbeam mounting hole, combined with the elastic deformation of the elastic sheet, can limit the displacement of the bracket body during installation, ensuring that the bracket and the crossbeam mounting hole always remain aligned, reducing the difficulty of later adjustment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-5 A photovoltaic support plate structure includes several plate bodies 5 installed on a photovoltaic support. Two parallel clamping plates 7 are fixedly connected to the bottom surface of the plate body 5. Two parallel positioning plates 8 are fixedly connected to the upper surface of the plate body 5. A limiting tube 13 is fixedly connected to the middle of the plate body 5. Two mounting ports 17 are opened through the lower end of the limiting tube 13. An elastic sheet 14 is fixedly connected to the inner wall of each mounting port 17. An extrusion assembly is connected inside the limiting tube 13. The upper end of the extrusion assembly extends through to the top of the limiting tube 13 and is connected to the limiting assembly.

[0024] like Figures 1 to 5 As shown, during installation, the photovoltaic support plate structure of this utility model first clamps the two clamps 7 on the bottom surface of the plate body 5 onto the crossbeam 4 of the photovoltaic support. During the clamping process, the lower end of the limiting tube 13 is aligned with one of the mounting holes of the crossbeam 4. Because the limiting tube 13 is longer than the clamps 7, the limiting tube 13 can be inserted into the mounting hole before the clamps 7 are clamped onto the crossbeam 4. Furthermore, because an elastic piece 14 is provided at one end of the limiting tube 13 that passes through the crossbeam 4, the limiting tube 13 will not slide out of the mounting hole of the crossbeam 4 without a large external force pulling it out.

[0025] As the limiting tube 13 is inserted, the clamp 7 is restricted to a specific position on the crossbeam 4. Then, several gas tray bodies 5 are installed in the same way. The four corners of the photovoltaic panel to be installed are placed on one side of the positioning plate 8 on the four tray bodies 5 so that the photovoltaic panel will not slide from the side. Then, it is fixed to the tray body 5 by the extrusion component and the limiting component. When the extrusion component and the limiting component limit the photovoltaic panel, the tray body 5 is also fixed to the crossbeam 4 at the same time, which is convenient and quick.

[0026] As a preferred embodiment of the present invention, the limiting component includes a base plate 9 and two L-shaped pressing blocks 6. The two sides of the upper surface of the base plate 9 are respectively fixedly connected to the lower ends of the two L-shaped pressing blocks 6. An adjustment port 16 is provided through the side of the two L-shaped pressing blocks 6 near the base plate 9. The upper end of the pressing component is located in the adjustment port 16.

[0027] The extrusion assembly includes a locking knob 10, a threaded rod 11, and a truncated cone 12. The locking knob 10 is located inside the adjustment port 16. The locking knob 10 is sleeved and threadedly connected to the outer wall of the threaded rod 11. The lower end of the threaded rod 11 extends through to the bottom of the limiting tube 13 and is fixedly connected to the upper end of the truncated cone 12.

[0028] The truncated cone 12 is narrower at the top and wider at the bottom. The diameter of the wider end of the truncated cone 12 is not greater than the diameter of the outer ring of the limiting tube 13, and the diameter of the wider end of the truncated cone 12 is not less than the diameter of the inner ring of the limiting tube 13.

[0029] Two openings 15 are formed through the bottom surface of the limiting tube 13.

[0030] A photovoltaic support bracket includes two rear columns 1, two front columns 2, two inclined beams 3 and two crossbeams 4. The photovoltaic support bracket also includes the aforementioned photovoltaic support bracket structure. Several mounting holes are provided through the bottom surface of each of the two crossbeams 4. A limiting tube 13 is slidably connected to the mounting holes of the crossbeams 4. Two clamping plates 7 are slidably connected to the two sides of the crossbeams 4 respectively.

[0031] More specifically, when it is necessary to install the photovoltaic panel on the tray body 5, first turn the locking knob 10 to lower the truncated cone 12 at the lower end of the threaded rod 11. At this time, the distance between the truncated cone 12 and the bottom surface of the limiting tube 13 changes. Then, lift the L-shaped pressure block 6. When the L-shaped pressure block 6 is lifted, it will bring the base plate 9 up with it. When the base plate 9 rises, it will lift the locking knob 10, the threaded rod 11 and the truncated cone 12 together until the truncated cone 12 stops again against the bottom surface of the limiting tube 13. At this time, the L-shaped pressure block 6 rises a certain distance, which is enough to place the photovoltaic panel on the tray body 5.

[0032] After the photovoltaic panels are installed, release the L-shaped pressure block 6. The L-shaped pressure block 6 and the base plate 9 will descend due to gravity. At this time, the locking knob 10, threaded rod 11, and truncated cone 12 will slide down together until the bottom surface of the base plate 9 rests on the upper surface of the photovoltaic panel. Then, place the other base plates 9 on the photovoltaic panel surface in the same manner. The installer then manually pulls the locking knob 10, threaded rod 11, and truncated cone 12 upwards. The locking knob 10 will slide along the adjustment port 16. When the truncated cone 12 abuts against the bottom surface of the limit tube 13, the locking knob 10 can be manually turned, or with a wrench or other tools. After turning, the locking knob 10 will descend again to the bottom of the adjustment port 16. At this point, the truncated cone 12 will continue to press against the bottom surface of the limiting tube 13. Then, the locking knob 10 will be turned by a wrench or other tools. Because there is a certain friction between the truncated cone 12 and the limiting tube 13, the threaded rod 11 and the truncated cone 12 will rise as the locking knob 10 is turned. When the truncated cone 12 rises, it will gradually insert into the interior of the limiting tube 13, and then gradually open the lower end of the limiting tube 13 with the two openings 15 until the truncated cone 12 rises to a specific position. At this point, the truncated cone 12 and the limiting tube 13 are completely squeezed together, and the tray body 5 and the crossbeam 4 can be locked together. At the same time, the photovoltaic panel is clamped by the base plate 9 and the tray body 5.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
