Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a photovoltaic module bridging assembly and its installation system. Background Technology
[0002] As the industry's demand for low-load-bearing rooftop photovoltaic modules increases, there is a need for even lighter photovoltaic modules. As a result, the glass panels of lightweight photovoltaic modules are becoming thinner and thinner, and the frame height and weight per meter of photovoltaic modules are also gradually decreasing.
[0003] When glass panels are selected to be 2.0mm or less per layer, the glass panels become increasingly soft. At the same time, the frame height and weight per meter also decrease, resulting in photovoltaic modules becoming very soft and their load-bearing capacity decreasing significantly, especially the back pressure.
[0004] Most of the reasons for the failure of rooftop photovoltaic module installation are that the photovoltaic modules deform and fall out of the clamping blocks; in addition, improper installation is also one of the reasons for installation failure. For example, if the front dimension of the clamping block is too narrow or the front clamping depth is insufficient during installation, the photovoltaic modules are easy to fall out of the clamping block under severe weather conditions such as typhoons. Utility Model Content

[0044] Compared to conventional bridging modules, the bridging module of this solution mainly adds a component, namely the lower pressure block 4. The lower pressure block 4 is pulled on the inner side of the frame 2-1 on the side of the photovoltaic module 2 to apply tension to the photovoltaic module 2.
[0045] Based on the limiting method of the pressure block 4, this scheme is mainly divided into three types.
[0046] The first type is: the pressure block 4 is limited by the fastener 6.
[0047] The second type is: the lower pressure block 4 is limited by the upper and lower hooks B9 and C10.
[0048] The third method is: in the middle pressure block assembly, self-limiting is achieved by the pull hooks A5 on both sides of the lower pressure block 4.
[0049] Implementation Example 1 of this solution is the first implementation method of this solution.
[0050] Embodiments 2, 3, 4, and 5 of this scheme are the second implementation methods of this scheme.
[0051] Embodiment 6 of this scheme is the third implementation of this scheme.
[0052] Example 1, as Figures 1-4 As shown, a bridging assembly for a photovoltaic module, specifically a side bridging assembly, is used for installing a photovoltaic module 2 on one side.
[0053] The photovoltaic module briquette assembly of this embodiment 1 includes:
[0054] Upper pressure block 1 is used to press on the front side of the photovoltaic module 2. Upper pressure block 1 has upper mounting hole 3. In this embodiment 1, the side frame of the photovoltaic module is a full-coverage frame. The upper pressure block 1 pressing on the front side of the photovoltaic module 2 is equivalent to the upper pressure block 1 pressing on the front side of the frame.
[0055] The pressure block 4 is used to support the back side of the photovoltaic module 2. The outer side of the pressure block 4 has an upward protruding hook A5, which is used to pull the inner side of the frame 2-1 of the photovoltaic module 2 to apply a pulling force to the photovoltaic module 2.
[0056] Fastener 6 passes through the upper mounting hole 3 and is used to apply pressure to the upper pressure block 1 after being connected to the mounting bracket 7, thereby pressing the upper pressure block 1, the side of the photovoltaic module 2, the lower pressure block 4 and the mounting bracket 7 together.
[0057] The lower pressure block 4 has a lower mounting hole 8, and the fastener 6 also passes through the lower mounting hole 8 to limit the lower pressure block 4 in the opposite direction of the tension applied by the lower pressure block 4 to the frame 2-1.
[0058] The upper pressure block 1 includes a connecting part A1-1, a support leg part 1-2, and a pressing part 1-3. The support leg part 1-2 and the pressing part 1-3 are located on both sides of the connecting part A1-1. The support leg part 1-2 is used to support the upper pressure block 1 on one side of the support leg part 1-2. The pressing part 1-3 is used to press on the front side of the photovoltaic module 2. The upper mounting hole 3 is located on the connecting part A1-1.
[0059] The lower pressure block 4 includes a connecting part B4-1 and a hook part 4-2. The hook part 4-2 is located on one side of the connecting part B4-1, the hook A5 is located on the outside of the hook part 4-2, and the lower mounting hole 8 is located on the connecting part B4-1.
[0060] The pressing part 1-3 of the upper pressing block 1 is L-shaped, including a horizontal plate pressing on the front side of the photovoltaic module 2 and a vertical plate blocking the side of the photovoltaic module 2.
[0061] The lower pressure block 4 is L-shaped.
[0062] Example 2, as Figures 5-8 As shown, a photovoltaic module clamping assembly is basically the same as in Embodiment 1, specifically a side clamping assembly used for mounting one side of the photovoltaic module 2. The difference is that the lower clamping block 4 does not have a connecting part B4-1. The upper clamping block 1 has a downward protruding hook B9, and the lower clamping block 4 has an upward protruding hook C10. The hook C10 is located inside the hook A5. The hook B9 and the hook C10 are hooked together to limit the lower clamping block 4 in the opposite direction of the pulling force applied by the lower clamping block 4 to the frame 2-1.
[0063] The hook B9 is located on the side of the connecting part A1-1 facing the pressing part 1-3, and is in a straight line with the vertical plate of the L-shaped pressing part 1-3 of the upper pressing block 1 in the vertical direction.
[0064] The pressure block 4 is U-shaped and is located on one side of the fastener 6.
[0065] Example 3, as Figures 9-12 As shown, a photovoltaic module clamping assembly is basically the same as that in Embodiment 2, except that the clamping assembly of the photovoltaic module in Embodiment 2 is specifically a middle clamping assembly, used for the installation of photovoltaic modules 2 on both adjacent sides. Both sides of the fastener 6 have U-shaped lower clamping blocks 4.
[0066] The upper pressure block 1 includes a connecting part A1-1 and a pressing part 1-3. The pressing part 1-3 is located on both sides of the connecting part A1-1. The pressing part 1-3 is used to press against the front side of the photovoltaic module 2. The upper mounting hole 3 is located on the connecting part A1-1. There are hooks B9 on both sides of the upper connecting part A1-1. The hooks B9 and the vertical plate of the L-shaped pressing part 1-3 on the same side of the upper pressure block 1 are aligned vertically.
[0067] Both sides of the fastener 6 have the same U-shaped pressing block 4 as in embodiment 2.
[0068] The hook B9 on one side of the upper pressure block 1 engages with the hook C10 on the lower pressure block 4 on the same side to limit the lower pressure block 4 in the opposite direction of the pulling force applied by the lower pressure block 4 to the frame 2-1.
[0069] Example 4, as Figure 13 and 14 As shown, a photovoltaic module clamping assembly is basically the same as that in Embodiment 1, specifically a side clamping assembly, used for installing a photovoltaic module 2 on one side. The difference is that the upper clamping block 1 has a downward protruding hook B9, and the lower clamping block 4 has an upward protruding hook C10. The hook C10 is located inside the hook A5. The hook B9 and the hook C10 are hooked together to limit the lower clamping block 4 in the opposite direction of the pulling force applied by the lower clamping block 4 to the frame 2-1.
[0070] Because the lower pressure block 4 can be limited by hook B9 and hook C10, it is no longer necessary to limit the lower pressure block 4 by fastener 6 passing through the lower mounting hole 8 of the lower pressure block 4, so the lower mounting hole 8 can be a large hole.
[0071] Example 5, as Figure 15 and 16 As shown, a photovoltaic module clamping assembly is basically the same as that in Embodiment 3, both being middle clamping assemblies. The structure of the upper clamping block 1 is also the same. The difference is that the lower clamping block 4 includes a connecting part B4-1 and a hook part 4-2. There are hook parts 4-2 on both sides of the connecting part B4-1. The hook A5 is located on the outside of the hook part 4-2. The lower mounting hole 8 is located on the connecting part B4-1, and the fastener 6 also passes through the lower mounting hole 8. The lower clamping block 4 of this Embodiment 5 is equivalent to connecting the two lower clamping blocks 4 of Embodiment 3 into a whole.
[0072] Example 6, as Figures 17-20 As shown, a type of photovoltaic module clamping assembly, specifically a medium-pressure clamping assembly, is used for mounting photovoltaic modules 2 on adjacent sides.
[0073] The photovoltaic module briquette assembly of this embodiment 6 includes:
[0074] Upper pressure block 1 is used to press on the front side of the photovoltaic module 2. Upper pressure block 1 has upper mounting holes 3.
[0075] The pressure block 4 is used to support the back side of the photovoltaic module 2. The outer side of the pressure block 4 has an upward protruding hook A5, which is used to pull the inner side of the frame 2-1 of the photovoltaic module 2 to apply a pulling force to the photovoltaic module 2.
[0076] Fastener 6 passes through the upper mounting hole 3 and is used to apply pressure to the upper pressure block 1 after being connected to the mounting bracket 7, thereby pressing the upper pressure block 1, the side of the photovoltaic module 2, the lower pressure block 4 and the mounting bracket 7 together.
[0077] The upper pressure block 1 includes a connecting part A1-1 and a pressing part 1-3. The connecting part A1-1 has pressing parts 1-3 on both sides. The pressing parts 1-3 are used to press on the front side of the photovoltaic module 2. The upper mounting hole 3 is located on the connecting part A1-1.
[0078] The lower pressure block 4 includes a connecting part B4-1 and a hook part 4-2. There are hook parts 4-2 on both sides of the connecting part B4-1. The hook A5 is located on the outside of the hook part 4-2. The lower mounting hole 8 is located on the connecting part B4-1. The fastener 6 also passes through the lower mounting hole 8.
[0079] The lower pressure block 4 is U-shaped.
[0080] In this embodiment 6, the middle pressure block assembly is self-limited by the hooks A5 on both sides of the lower pressure block 4, and it is no longer necessary to limit the lower pressure block 4 by the fastener 6 passing through the lower mounting hole 8 of the lower pressure block 4. Therefore, the lower mounting hole 8 can also be a large hole.
[0081] Example 7, as Figure 21 and 22 As shown, a photovoltaic module installation system includes a photovoltaic module 2, a clamping assembly, and a mounting bracket 7. The photovoltaic module is installed by the clamping assembly and the mounting bracket 7.
[0082] In this embodiment 7, the mounting bracket 7 is as follows: Figure 21 As shown, the mounting bracket 7 has mounting grooves on both its upper and lower surfaces. The fastener 6 includes a bolt and a nut. The bolt is screwed into the nut embedded in the mounting groove on the upper surface of the mounting bracket 7 to connect the fastener 6 to the mounting bracket 7. The mounting groove on the lower surface of the mounting bracket 7 is used to connect the mounting bracket 7 to the mounting base, such as a corrugated steel roof.
[0083] The outer edge of the photovoltaic module located at the edge of the photovoltaic module installation system can be connected to the mounting bracket 7 by the edge pressure block assembly of embodiment 1, 2 or 4. The adjacent sides of two adjacent photovoltaic modules 2 within the photovoltaic module installation system can be connected to the mounting bracket 7 by the middle pressure block assembly of embodiment 3, 5 or 6.
