For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings.
[0031] like Figure 1-2 As shown, a BIPV photovoltaic building integrated power generation device includes a photovoltaic module 1 and a scaffolding 2. Both sides of the scaffolding 2 are fixed to the load-bearing wall. Both sides of the scaffolding 2 are fixed with a gutter trough 11 and a downpipe 12.
[0032] A drainage mechanism 3 is also provided, such as Figure 3-5As shown, the drainage mechanism 3 includes a plurality of M-shaped longitudinal water tanks 31 arranged in parallel and fixed on the scaffold 2 by self-tapping screws, a component support tray 32 is fixed on the M-shaped longitudinal water tank 31, and a U-shaped transverse water tank 33 is arranged at both ends of the photovoltaic module 1. The two ends of the U-shaped transverse water tank 33 are arranged opposite to the M-shaped longitudinal water tank 31 and are provided with overflow ports 331 to prevent the photovoltaic module 1 from being soaked in water when the U-shaped transverse water tank 33 is blocked. The two sides of the photovoltaic module 1 are connected to the component support tray 32 through the intermediate pressure piece 4, and the intermediate pressure piece 4 is clamped with a protective cover plate 5 to protect the intermediate pressure piece 4. The two ends of the component support tray 32 are symmetrically provided with connecting parts, which are fixedly connected to the side of the M-shaped longitudinal water tank 31 by self-tapping screws, and the component support tray 32 is provided with a waterproof groove 321 to prevent the water outlet of the U-shaped transverse water tank 33 from flowing along the component support tray 32 to the outside of the M-shaped longitudinal water tank 31. A sealing gasket 322 is provided on the top of the connecting part to improve the sealing performance.
[0033] This embodiment is a human-shaped roof, with a ridge support member 7 fixed on the top of the M-shaped longitudinal water tank 31, the top of the ridge support member 7 is fitted with the ridge cover plate 10, and the first sealing strips 8 are fixed on both sides of the ridge cover plate 10 to improve the sealing performance. The two sides of the ridge cover plate 10 are arranged between the U-shaped transverse water tank 33 and the photovoltaic module 1 to achieve the crimping of the ridge cover plate 10. A second sealing strip 9 is arranged in the transverse gap between the photovoltaic modules 1 to achieve the basic sealing of the transverse gap. Once a water leak occurs, the leaked water can also be diverted to the M-shaped longitudinal water tank 31 through the diversion effect of the U-shaped transverse water tank 33.
[0034] like Figure 6-7 As shown, a walkway mechanism 6 for maintenance personnel to walk on is also provided to facilitate maintenance by the staff. The walkway mechanism 6 is arranged between the two M-shaped longitudinal water tanks 31 and includes a walkway plate 61. The two sides of the walkway plate 61 are fixedly connected to the component support tray 32. A walkway plate support 62 is fixed on the scaffold 2, and the top of the walkway plate support 62 is clamped with the walkway plate 61. Fixed grooves 611 are provided on both sides of the walkway plate 61, and a protective sheet 612 is fixed through the fixed groove 611. The protective sheet 612 is made of rubber material and serves to protect the gap between the walkway plate 61 and the photovoltaic component 1, so as to facilitate cleaning of debris. At least one pair of card plates 613 is provided at the bottom of the walkway plate 61, and each pair of card plates 613 is arranged opposite to each other, and a card slot is provided on the inner side of the card plate 613. The cross section of the walkway support 62 is a "X"-shaped structure. The bottom of the walkway support 62 is fixed to the purlin of the shelf 2. The walkway support 62 is provided with snap-fitting convex strips on both sides, and the snap-fitting convex strips are arranged in the card slots. Figure 8 As shown, the self-tapping screws are used for installation, which destroys the sealing of the walkway plate 61 and is inconvenient to disassemble.
[0035] Rainwater diversion direction:
[0036] Rainwater passing through the longitudinal gaps of the photovoltaic module 1 is collected by the M-shaped longitudinal gutter 31. Rainwater passing through the transverse gaps of the photovoltaic module 1 is first blocked by the second sealing strip 9 and flows into the gutter gutter 11 along the surface of the photovoltaic module 1. Rainwater that cannot be blocked by the second sealing strip 9 is collected by the U-shaped transverse gutter 33. Rainwater from the U-shaped transverse gutter 33, the ridge cover plate 10 and the walkway plate 61 are merged into the M-shaped longitudinal gutter 31. Multiple M-shaped longitudinal gutteres 31 are connected to the gutter gutter 11. Rainwater is discharged into the downpipe 12 through the gutter gutter 11, thereby improving the rainproof performance of the photovoltaic module 1 and can be used as a factory roof.
[0037] The M-shaped longitudinal water trough 31 is both a drainage structure and a bearing structure for fixing the photovoltaic assembly 1, which is beneficial to reducing costs.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
