Description

Technical Field

[0001] The utility model relates to the technical field of BIPV photovoltaic systems, and in particular to a fixing component of a BIPV photovoltaic system. Background Art

[0002] BIPV stands for Building Integrated Photovoltaics, which is a building integrated photovoltaic power station system that integrates solar panels into building facades, roofs, etc. The installation of photovoltaic modules on the gutter is a key point of the BIPV photovoltaic system, affecting the stability and waterproofness of the BIPV photovoltaic system.

[0003] There are two main existing installation methods: one is to press the photovoltaic module directly onto the water gutter through a pressing block. The pressing block is generally connected in the middle of the water gutter by bolts. This connection method destroys the waterproofness of the water gutter, and the bolt mounting hole in the middle of the water gutter has the risk of leakage; the second is to connect the water gutter and the photovoltaic module through a fixed component. For example, the Chinese utility model patent with application number CN202220521915.7 discloses an adjustable pressing block assembly suitable for BIPV. Although this installation structure ensures the waterproofness of the M-shaped water gutter, its installation operation has safety hazards. It requires installation workers to climb above the photovoltaic module to install the component pressing block from top to bottom and tighten the bolts. The surface of the photovoltaic module is smooth. For roofs with open space on all sides such as sloping roofs, high-altitude operations are extremely inconvenient and there are great safety risks.

The fixing assembly includes a bracket 1, a female fastener 2, a first bolt 3, a male fastener 4, a locking block 5 and a second bolt 6. The bracket 1 is installed on the water channel 8, the female fastener 2 is locked and installed on the bracket 1 through the first bolt 3, the male fastener 4 is clamped and installed on the female fastener 2, and the locking block 5 is installed on the male fastener 4 through the second bolt 6. The locking block 5 is used to press the photovoltaic assembly 9 on the male fastener 4. During installation, the female fastener 2 can be pre-assembled on the bracket 1, the male fastener 4 can be assembled on the photovoltaic assembly 9, and then the male fastener 4 can be clamped into the female fastener 2 to achieve rapid installation of the photovoltaic assembly 9, thereby improving construction efficiency. During disassembly, unscrew the first bolt 3, and the photovoltaic assembly 9 and the fixing assembly (except the bracket 1) can be quickly removed from the water channel 8, and disassembled and repaired separately, thereby improving the repair efficiency.

[0030] Specifically, the bracket 1 of this embodiment includes two second side plates 12 arranged opposite to each other and a bearing plate 11 connected between the two second side plates 12. A first threaded hole 111 threadedly connected to the first bolt 3 is provided in the middle of the bearing plate 11, and limiting protrusions 112 are respectively provided on both sides of the first threaded hole 111 of the bearing plate 11, and third through holes 121 are respectively provided in the two second side plates 12. The bracket 1 is mounted on the water channel 8, and the two second side plates 12 of the bracket 1 are respectively locked and connected with the side walls of the water channel 8 by the bolt assemblies 7 penetrating the third through holes 121, thereby fixing the bracket 1 on the water channel 8.

[0031] The female fastener 2 of this embodiment adopts a split design, which includes two clamping seats 21 and an upper pressing member 22 for pressing the two clamping seats 21 onto the bracket 1.

[0032] Two clamping seats 21 are symmetrically arranged on the bracket 1. The clamping seats 21 are provided with side sockets 212 for clamping the male fastener 4. A half hole 214 is provided on one side of the clamping seat 21. A limiting side wall 215 protruding upward is formed on the other side of the clamping seat 21. A slot 213 is provided between the half hole 214 and the limiting side wall 215. A limiting groove 211 is provided at the bottom of the clamping seat 21. The limiting groove 211 is plugged and matched with the limiting protrusion 112 to play a limiting role, so as to prevent the clamping seat 21 from moving and affecting the clamping of the male fastener 4.

[0033] The upper pressing member 22 includes two first side plates 222 arranged opposite to each other and a connecting plate 223 connected between the two first side plates 222, and a first through hole 221 is provided in the middle of the connecting plate 223. The two first side plates 222 of the upper pressing member 22 are respectively inserted into the slots 213 of the corresponding card holders 21 to fix the two card holders 21 as a whole and restrict the card holders 21 from sliding. The half holes 214 of the two card holders 21 are relatively assembled to form a second through hole. The first bolt 3 passes through the first through hole 221 and the second through hole in turn and is screwed into the first threaded hole 111 to press and fix the two card holders 21 between the upper pressing member 22 and the bracket 1.

[0034] This embodiment is provided with two male fasteners 4, corresponding to two holders 21 one by one. The male fastener 4 includes a clamping plate 41 and an elastic hook 42 connected to the clamping plate 41. The end of the clamping plate 41 away from the elastic hook 42 is provided with a waist-shaped adjustment hole 411, which is used to adjust the installation position of the lock block 5 according to the frames of photovoltaic modules 9 of various specifications, so as to improve the versatility of the fixing assembly of this embodiment. The elastic hook 42 is inserted into the side socket 212 and clamped with the holder 21 to lock the clamping plate 41 on the holder 21. The clamping plate 41 is limited between the limiting side walls 215 on both sides. The limiting side walls 215 limit the male fastener 4 to prevent the gap between the male fasteners 4 from being too large and can be fine-tuned.

[0035] The elastic hook 42 includes an elastic cantilever 421 and a barb 422. One end of the elastic cantilever 421 is connected to the clamping plate 41, and the other end is connected to the barb 422. The barb 422 protrudes in the direction away from the clamping plate 41. When the elastic hook 42 is inserted from one end of the side socket 212 and moved to the other end, the barb 422 contacts the bottom wall of the side socket 212, and the elastic cantilever 421 is elastically deformed. After being inserted into place, the barb 422 pops out from the other end of the side socket 212 and hooks with the clamping seat 21, locking the clamping plate 41 on the clamping seat 21. The barb 422 plays a certain limiting role, which can prevent the male fastener 4 from moving backward.

[0036] In order to facilitate the adjustment of the locking block 5 , the locking block 5 of this embodiment is provided with a second threaded hole 51 , and the second bolt 6 passes through the adjustment hole 411 and is screwed into the second threaded hole 51 .

[0037] The fixing assembly of this embodiment can simultaneously install two photovoltaic modules 9 on the water channel 8, and adopts a split design, which is conducive to reducing the cost of maintenance and replacement, and also facilitates the independent safety and maintenance of each photovoltaic module 9.
