Description

Technical Field

[0001] This utility model relates to the field of roof photovoltaic support technology, specifically to a lightweight guide rail photovoltaic support system suitable for large metal roofs. Background Technology

[0002] Metal roofing uses high-quality metal as the roof surface. Its base plate undergoes anti-corrosion treatment such as galvanizing and aluminum zinc plating, and is coated with a coating to resist corrosion from rain, snow, wind and dust. In addition, the metal material itself is non-combustible, giving the roof fireproof and flame-retardant function.

[0003] Metal roof panels are usually fixed together by standing seam or standing seam interlocking plate. Taking standing seam as an example, it connects the roof panels with each other to ensure the stability between multiple roof panels and prevent rainwater from flowing into the roof from the gaps between the roof panels.

[0004] When installing a conventional ground-mounted photovoltaic (PV) system, a concrete pier is first poured into the ground, and threaded rods are embedded in the pier. Then, the support rods or support seats of the PV system are installed onto the threaded rods of the pier using screws.

[0005] However, existing photovoltaic brackets have some drawbacks when installed on metal roofs, such as:

[0006] First, in order to ensure waterproofing, the roof panels of the metal roof cannot be damaged. However, conventional photovoltaic brackets need to be installed by screws or welding, which will damage the roof panels. Therefore, the existing photovoltaic bracket system cannot be installed on the metal roof without damaging the roof panels.

[0007] Secondly, existing photovoltaic brackets require welding multiple support rods, support bases and other parts. Metal roofs are relatively smooth and steep, which is more dangerous than the ground. Welding photovoltaic brackets on the roof is also more dangerous.

[0008] Therefore, the above two points make existing photovoltaic support systems unsuitable for metal roofs.

[0009] Therefore, this utility model provides a lightweight guide rail photovoltaic support system suitable for large metal roofs to solve the above problems. Utility Model Content

[0010] In view of the above situation and to overcome the defects of the prior art, this utility model provides a lightweight guide rail photovoltaic support system suitable for large metal roofs, so as to solve the problem that the existing photovoltaic support system is not suitable for metal roofs.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0012] A lightweight rail-mounted photovoltaic support system suitable for large metal roofs includes alloy ribs and support rod assemblies;

[0013] Alloy ribs: There are no fewer than two alloy ribs arranged in a straight line array. The lower end of the alloy rib is fixedly connected to an inner support seat, and the middle straight line array is provided with an extension hole. The straight line array inside the alloy rib is equipped with a fastener.

[0014] Support rod assembly: The support rod assembly includes a first support rod, a second support rod, and a third support rod. The first support rod rotates at the upper end of the alloy rib. The lower end of the second support rod rotates through a double-ended screw between itself and one of the extension holes. Both ends of the double-ended screw are threaded with a third nut. The two third nuts clamp the alloy rib. The upper end of the first support rod is hinged to the upper end of the second support rod. The lower end of the third support rod is welded and fixedly inserted into the inner support seat. A lightweight guide rail for top support is fixedly connected between the upper ends of a row of third support rods and a row of second support rods.

[0015] Through the above technical solution, the alloy ribs and support rod assemblies can be installed separately. When installing the alloy ribs first, the device is secured to the upright locking edge of the metal roof using clips. The alloy ribs are sandwiched between two adjacent upright locking edges without welding, which avoids damage to the metal roof and provides workers with footholds after the alloy ribs and clips are installed, improving safety and facilitating the subsequent installation of the support rod assemblies. Multiple clips are installed on each alloy rib to improve the stability of the device. The top support lightweight guide rail is supported by three rods: the first support rod, the second support rod, and the third support rod. The first support rod provides an upward pulling force, while the second and third support rods provide support force, thereby improving the stability of the top support lightweight guide rail. The tilt angle of the top support lightweight guide rail can be adjusted by rotating the first, second, and third support rods, thereby controlling the tilt angle of the photovoltaic panels.

[0016] Preferably, the fastener includes a first nut, a short-pitch double-ended screw, a long-pitch double-ended screw, and a fixing member. There are two short-pitch double-ended screws and two long-pitch double-ended screws, both of which move through the alloy rib. The first nut is threaded onto both ends of the short-pitch double-ended screw and the long-pitch double-ended screw. The first nut abuts against the side of the alloy rib. The fixing member is installed at both ends of the short-pitch double-ended screw and the long-pitch double-ended screw.

[0017] Preferably, the fastener includes two clamping plates and two second nuts. The end of the short-pitch double-ended screw or the long-pitch double-ended screw moves through the two clamping plates. The lower end of the two clamping plates on the side that is close to each other is provided with a groove. The end of the short-pitch double-ended screw or the long-pitch double-ended screw is threaded through the two second nuts. The two clamping plates are clamped in the middle of the two second nuts.

[0018] Preferably, an intermediate rod is rotatably connected to the upper end of the first support rod, and the other end of the intermediate rod is rotatably connected to the upper end of the second support rod, so that the first support rod and the second support rod are hinged together through the intermediate rod.

[0019] Preferably, a frame mounting base is rotatably connected to the upper end of the second support rod and the upper end of the third support rod, and the top support is fixedly connected to the two rows of frame mounting bases by a lightweight guide rail.

[0020] Preferably, the upper end of the alloy rib is integrally formed with a ridge handle buckle, and the vertical cross-section of the ridge handle buckle is ∧-shaped.

[0021] Preferably, an auxiliary rib is integrally formed at the other end of the ridge handle buckle, the auxiliary rib is inclined downward, and a fastener is also installed inside the auxiliary rib.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. The alloy ribs and support rod assemblies can be installed separately. When installing the alloy ribs first, use clips to fasten the device to the upright locking edge of the metal roof. The ridge handle is fastened to the ridge, and the auxiliary ribs are fixed inside the other side of the metal roof. The alloy ribs are sandwiched between two adjacent upright locking edges to ensure the safety and stability of the device. The entire installation process does not require welding. Firstly, it avoids damage to the metal roof. Secondly, after installing the alloy ribs and clips, it provides a foothold for workers, improving safety and facilitating the subsequent installation of the support rod assemblies. Thirdly, it provides a base point for the subsequent support rod assemblies.

[0024] 2. Multiple fasteners are installed on each alloy rib, and multiple alloy ribs are set on each roof to ensure that they can bear the weight of the photovoltaic panel and improve the stability of the device and the photovoltaic panel;

[0025] 3. The top support lightweight guide rail is supported by three rods: the first support rod, the second support rod, and the third support rod. The first support rod provides an upward pulling force, while the second and third support rods provide a supporting force, thereby improving the stability of the top support lightweight guide rail.

[0026] 4. The tilt angle of the top support lightweight guide rail can be adjusted by rotating the first support rod, the second support rod, and the third support rod, thereby controlling the tilt angle of the photovoltaic panel.

[0027] In summary, this device can secure the upright locking edge of a metal roof and features a series of drill-free bottom clamping structures, including snap fasteners, alloy ribs, ridge holding clips, and auxiliary ribs, without damaging the metal roof. An adjustable support rod assembly connects the lightweight guide rail for top support to the roof, with an angle adjustment function to accommodate roof unevenness and installation tilt requirements. This device utilizes a completely mechanical connection structure, eliminating the need for welding, and achieves fast, safe, and standardized installation of the photovoltaic system without damaging the original roof.

[0037] The following will refer to the attached reference. Figures 1 to 8The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0038] As attached Figure 5 As shown, the metal roof mainly consists of roof panels b and a ridge a. Roof panels b are welded along the edge of the ridge a. The roof panels b are arranged in a straight line array, and two adjacent roof panels b interlock to form a vertical interlocking edge c. This is the conventional structure of a metal roof, which will not be described in detail here.

[0039] As attached Figure 1 - Appendix Figure 8 As shown, a lightweight rail-mounted photovoltaic support system suitable for large metal roofs includes alloy ribs 1, ridge holding buckles 2, and support rod assemblies.

[0040] Roof Ridge Holding Buckle 2: See Appendix Figure 1 Appendix Figure 4 and attached Figure 6 The vertical cross section of the ridge holding buckle 2 is ∧-shaped, that is, the included angle between the two sides is less than 180°. The lower ends of the two sides of the ridge holding buckle 2 are integrally formed with auxiliary ribs 3 and alloy ribs 1 respectively. During installation, the auxiliary ribs 3 are installed on the roof panel b of the sun-shading metal roof, the ridge holding buckle 2 is clamped down on the ridge a, and the alloy ribs 1 are installed on the roof panel b of the sun-facing metal roof.

[0041] See appendix Figure 1 and attached Figure 4 The ridge-holding buckle 2, auxiliary rib 3, and alloy rib 1 form an integral rib, with no fewer than two of them installed in a straight array on the metal roof. The specific installation method is as follows:

[0042] See appendix Figure 1-8 Alloy rib 1 and auxiliary rib 3 are both installed on the roof panel b of the metal roof, that is, alloy rib 1 and auxiliary rib 3 are both located in the middle of two vertical interlocking edges c. The upper side of alloy rib 1 is provided with an inner groove 9 in a straight line array. An inner support seat 15 is fixedly connected in the inner groove 9 at the lower end of alloy rib 1. One end of the inner support seat 15 is an open structure and the opening diameter is enlarged relative to the bottom. The two opposite sides of the inner groove 9 at the middle of alloy rib 1 are provided with extension holes 10 in a straight line array. The entire alloy rib 1 is installed with a snap fastener 4 in a straight line array. The snap fastener 4 is located in the middle of two adjacent inner grooves 9. The auxiliary rib 3 is also installed with a snap fastener 4.

[0043] Support rod assembly: See appendix Figure 1-8 The support rod assembly includes a first support rod 5, a second support rod 6, and a third support rod 8;

[0044] First support rod 5: The lower end of the first support rod 5 rotates within the inner groove 9 at the upper end of the alloy rib 1 via a rotating shaft;

[0045] Second support rod 6: The lower end of the second support rod 6 is located in the inner groove 9 at the middle end of the alloy rib 1. The second support rod 6 and the extension holes 10 on both sides of the inner groove 9 are rotatably passed through by a double-ended screw 12. Both ends of the double-ended screw 12 are threaded with a third nut 11, and the two third nuts 11 clamp the alloy rib 1.

[0046] The connection between the first support rod 5 and the second support rod 6 is as follows: an intermediate rod 13 is rotatably connected to the upper end of the first support rod 5, and the other end of the intermediate rod 13 is rotatably connected to the upper end of the second support rod 6, so that the first support rod 5 and the second support rod 6 are hinged together through the intermediate rod 13.

[0047] The lower end of the third support rod 8 is welded and fixed inside the inner support seat 15;

[0048] A frame mounting base 14 is rotatably connected to the upper end of the second support rod 6 and the upper end of the third support rod 8. A lightweight top support rail 7 is fixedly connected between the two rows of frame mounting bases 14, and the photovoltaic panel can be fixed in the lightweight top support rail 7.

[0049] In this embodiment, refer to the appendix. Figure 1 Appendix Figure 3 and attached Figure 4 The fastener 4 includes a first nut 41, a short-pitch double-ended screw 42, a long-pitch double-ended screw 43, and a fixing member 44. There are two short-pitch double-ended screws 42 and two long-pitch double-ended screws 43, and both of them move through the alloy rib 1. The first nut 41 is threaded on both ends of the short-pitch double-ended screw 42 and the long-pitch double-ended screw 43. The first nut 41 abuts against the side of the alloy rib 1. The fixing member 44 is installed on both ends of the short-pitch double-ended screw 42 and the long-pitch double-ended screw 43.

[0050] The fastener 44 includes two clamping plates 4401 and two second nuts 4402. The end of the short-pitch double-ended screw 42 or the long-pitch double-ended screw 43 moves through the two clamping plates 4401. The lower end of the two clamping plates 4401 on the side that is close to each other is provided with a groove. The end of the short-pitch double-ended screw 42 or the long-pitch double-ended screw 43 is threaded through the two second nuts 4402. The two clamping plates 4401 are clamped in the middle of the two second nuts 4402.

[0051] It is worth noting that: the two clamping plates 4401 of the fixing parts 44 at both ends of the short-pitch double-ended screw 42 clamp onto the upright interlocking edges c on both sides of the roof panel b where the alloy rib 1 is located, and the two clamping plates 4401 of the fixing parts 44 at both ends of the long-pitch double-ended screw 43 clamp onto the upright interlocking edges c on both sides of other roof panels b.

[0052] The installation method of this device is as follows: First, install the entire rib of the first alloy rib 1, the ridge holding buckle 2, and the auxiliary rib 3 on the metal roof. Refer to the above for the installation method. Then, use the two clamps 4401 of the fixing parts 44 at both ends of the short-pitch double-ended screw 42 and the two clamps 4401 of the fixing parts 44 at both ends of the long-pitch double-ended screw 43 to clamp the upright interlocking edge c. This completes the installation of the first entire rib. After that, the worker can step on the buckle 4 of the alloy rib 1 while wearing a safety rope to install the subsequent entire ribs. Refer to the installation method of the first entire rib.

[0053] It should also be noted that during the installation of the entire rib, the first support rod 5 is always rotatably connected to the alloy rib 1, but the lower end of the second support rod 6 is not aligned with the extension hole 10. In other words, the entire rib, the third support rod 8, the first support rod 5 and the second support rod 6 are transported to the roof together, while the lightweight guide rail 7 for the top support is transported to the roof separately.

[0054] After all the alloy ribs 1, ridge holding buckle 2 and auxiliary ribs 3 are installed on the metal roof, the fasteners 4 on the metal roof become the force base points. At this time, the lower end of the second support rod 6 can be installed. According to the angle required by the photovoltaic panel, the lower end of the second support rod 6 can be aligned with the corresponding extension hole 10. After alignment, it passes through the double-ended screw 12, and two third nuts 11 are threaded onto the two ends of the double-ended screw 12 and clamp the alloy rib 1 to fix the second support rod 6.

[0055] Then, the top support is fixed to the two sides of the lightweight guide rail 7 with screws on the frame mounting base 14 at the upper end of the second support rod 6 and the frame mounting base 14 at the upper end of the third support rod 8;

[0056] The photovoltaic panels can be fixed on the lightweight guide rail 7 during installation.
