Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a BIPV waterproof support system, which is suitable for the installation of photovoltaic modules in building scenarios such as rooftops and curtain walls. Background Technology

[0002] BIPV, or Building Integrated PV, combines photovoltaics into the building structure, achieving a synergy between power generation and building functionality. However, the waterproofing of the vertical gaps between modules has long been a constraint on its reliability and lifespan. Traditional solutions often use aluminum alloy snap-fit ​​covers, but these have the following drawbacks:

[0003] Poor wind resistance: The snap-fit ​​connection is easily affected by strong winds, which can cause the cover plate to fall off, allowing a large amount of rainwater to enter the M-shaped water tank, causing short circuits or building leaks.

[0004] Insufficient sealing: Snap-on installation makes it difficult to achieve a tight fit, leaving tiny gaps. After long-term use, material deformation can easily lead to waterproofing failure.

[0005] Low durability: Aluminum alloys are prone to corrosion in harsh climates, which affects their service life.

[0006] Therefore, there is an urgent need for a BIPV waterproof support system that is simple in structure, easy to install, and has excellent waterproof performance. Utility Model Content

Example 1

[0036] See Figures 1-7 , Figure 1 A structural schematic diagram of a BIPV waterproof support system is shown. As shown in the figure, this embodiment of the BIPV waterproof support system includes an M-shaped water trough 2, a transverse water trough 3, a pressure block fixing plate 4, a central pressure block 5, a side pressure block 6, and a steel cover plate 7.

[0041] The M-shaped water tank 2 has an M-shaped cross-section and includes a bottom plate 21 and supporting members symmetrical about the central axis of the bottom plate 21. The supporting members include a top plate 22, with an inner side plate 23 and an outer side plate 24 connected to both ends of the top plate 22.

The top plate 22 is smoothly connected to the inner side plate 23 and the outer side plate 24, and the outer side plate 24 is smoothly connected to the pressing edge 25.

[0042] The included angle between the base plate 21 and the inner side plate 23 is 100°~130°, and the included angle between the outer side plate 24 and the pressing edge 25 is 80°~110°.

[0043] The pressure block fixing plate 4 includes a middle fixing plate 41. The center of the middle fixing plate 41 is provided with a protruding post 411.

[0044] The left end of the fixed plate 41 is connected to one end of the first inclined plate 42 that slopes downward to the left. The other end of the first inclined plate 42 is connected to one end of the second inclined plate 44 that slopes upward to the left via a horizontal connecting plate 43. The other end of the second inclined plate 44 is connected to the third inclined plate 45 that slopes downward to the left. Thus, a lower groove is formed between the first inclined plate 42 and the second inclined plate 44, and a clamping groove is formed between the second inclined plate 44 and the third inclined plate 45. This clamping groove matches the protrusion of the M-shaped water tank 2, and the clamping groove and the third inclined plate 45 cover the protrusion of the M-shaped water tank 2.

[0048] The steel cover plate 7 is made of high-strength galvanized steel plate with a fluorocarbon coating to enhance corrosion resistance. Example 2

[0049] See Figure 8 , Figure 8 A structural schematic diagram of the steel cover plate in Embodiment 2 is shown. As shown in the figure, the BIPV waterproof support system in Embodiment 2 differs from that in Embodiment 1 in that:

[0050] The steel cover plate 7 has downward-extending "L"-shaped folded edges at both ends of the cover plate body 71, which are embedded with silicone sealing strips on the contact surface with the photovoltaic module to form a physical sealing barrier.

[0051] The steel cover plate 7 is fixed by T-bolts pre-installed below the central pressure block 5. The bolt heads are embedded in the reserved grooves of the steel cover plate 7 and locked by spring washers to prevent loosening.

[0052] The intermediate pressure block 5 is equipped with a spring mechanism, which can automatically adjust the clamping force according to the thickness of the component to ensure that the steel cover plate 7 is tightly fitted to the photovoltaic module.

[0053] Stainless steel anchor bolts are added to both ends of the intermediate pressure block 5 to penetrate the building base and fix it, thereby enhancing the overall pull-out resistance.

[0054] Working principle:

[0055] This utility model provides a BIPV waterproof support system, in which the support base is fixed to the building structure by anchor bolts, the position of the slide rail is adjusted to match the width of the module, after the photovoltaic module is placed, an adaptive pressure block is installed, and the spring mechanism automatically presses the edge of the module; the L-shaped fold of the steel cover plate is aligned with the gap of the module, a silicone sealing strip is embedded, and it is fixed to the bottom of the pressure block by T-bolts.

[0056] This invention installs a steel cover plate below a pressure block, which then fixes the cover plate to the vertical gap between the components. This installation method creates a tight connection between the steel cover plate, the pressure block, and the components, greatly enhancing the stability of the cover plate. Even in extreme wind conditions, strong winds are unlikely to shake the position of the steel cover plate, effectively solving the problem of traditional cover plates being easily blown away, and providing reliable protection for the waterproof performance of the BIPV system.

[0057] The pressure applied by the clamping blocks to the steel cover plate ensures a tight seal against the component surface, forming an effective waterproof seal. Simultaneously, the high strength and rigidity of the steel cover plate itself allow it to maintain a stable shape under strong wind pressure, preventing deformation or displacement due to external forces. This design not only improves waterproof performance but also enhances the structural stability of the entire BIPV system to a certain extent. Furthermore, the material properties of the steel cover plate give it excellent corrosion resistance and durability, enabling long-term stable operation in various complex climatic environments, further reducing the maintenance costs and replacement frequency of the BIPV system.

[0058] Through on-site installation and long-term monitoring of multiple BIPV projects, it has been found that the system using the steel cover plate of this utility model maintains excellent waterproof performance after enduring numerous severe weather conditions such as strong winds and heavy rains, and no component failures have occurred due to rainwater intrusion. Compared with traditional briquette cover plate systems, the failure rate of this utility model system is significantly reduced, and the number of maintenance operations is greatly decreased, bringing economic benefits and operational assurance to the project.

[0059] In conclusion, BIPV sectional cover plates play a crucial role in building-integrated photovoltaic (BIPV) systems, not only solving the long-standing waterproofing problem in the industry but also providing strong support for the stable operation and widespread application of BIPV systems. With continuous technological advancements and innovations, it is believed that BIPV sectional cover plate technology will continue to improve, playing an even greater role in promoting the development of the building-integrated photovoltaic industry.

[0060] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
