Description

Technical Field

[0001] The utility model relates to the technical field of solar energy, in particular to a rooftop photovoltaic device. Background Art

[0002] Photovoltaic roofs are photovoltaic panels installed on the top of houses, which are used to generate electricity to achieve energy conservation and emission reduction goals. For the convenience of layout and aesthetics, photovoltaic panels on roofs are usually arranged into multiple photovoltaic tiles. When laying photovoltaic tiles, waterproof glue is usually directly applied or cement mortar is used to seal the corners of the roof to form a ridge. After long-term exposure to the sun, the waterproof glue will crack, allowing rainwater to leak under the photovoltaic tiles, causing roof leaks. In addition, the appearance of the building is affected by the inconsistency between the color of cement mortar and photovoltaic tiles. The direct bonding of cement mortar and photovoltaic tiles can only be destructively removed for later maintenance, which is inconvenient for the maintenance of photovoltaic tiles.

[0036] The utility model discloses a roof photovoltaic device, referring to Figure 1 and Figure 2As shown, the rooftop photovoltaic device of this embodiment includes a drainage member 100, a photovoltaic tile 200 and a waterproof membrane 300. The drainage member 100 can be detachably installed at the corner of the roof. The drainage member 100 has a drainage groove 111 along its length direction. The photovoltaic tile 200 is used to be laid on the roof and is located on both sides of the drainage member 100 along its width direction. The waterproof membrane 300 is installed on the drainage member 100, and a part of the waterproof membrane 300 extends into the drainage groove 111, and another part of the waterproof membrane 300 extends out of the drainage groove 111 and is connected to the photovoltaic tile 200. It is understandable that, compared with the prior art of filling cement or waterproof glue to form a ridge at the corner of the roof, in this embodiment, the drainage piece 100 connected to the corner of the roof is used as the ridge, and a waterproof membrane 300 is provided on the drainage piece 100. The waterproof membrane 300 is connected to the photovoltaic tile 200 at both ends along its width. The presence of the waterproof membrane 300 can prevent the water on the surface of the photovoltaic tile 200 from gathering at the location of the drainage piece 100 and then seeping under the waterproof piece, and even after long-term use, it can still ensure good waterproof performance. At the same time, the installation of the drainage piece 100 and the roof can be disassembled, and the waterproof membrane 300 can also be easily torn off from the surface of the photovoltaic tile 200 and replaced with a new waterproof membrane 300, thereby facilitating the maintenance of the photovoltaic tile 200.

It can be understood that the packaging member 700 is machined in the factory, and is more beautiful in appearance than the existing centralized cement mortar and waterproof glue 600, and can also provide certain protection for the waterproof membrane 300, reducing the probability of damage to the waterproof membrane 300.

[0048] Further, refer to Figure 2 As shown, the package 700 includes a package body 710 and two connecting parts 720. The package body 710 stops at the waterproof membrane 300 and presses the waterproof membrane 300 into the drainage groove 111. The two connecting parts 720 are connected to both sides of the package body 710 along its width direction, and each connecting part 720 is detachably connected to the photovoltaic tile 200. In the actual fixing process, the package 700 is fixed by connecting the two connecting parts 720 to the photovoltaic tile 200. The two-side fixing method can further improve the connection stability of the package 700 and the photovoltaic tile 200.
