Description

Technical Field

[0001] The invention relates to the technical field of rooftop photovoltaics, and in particular to a photovoltaic tile roof. Background Art

[0002] In order to realize the effective use of solar energy, photovoltaic tile systems are usually installed in places with more sunlight, such as photovoltaic carports or photovoltaic roofs. They can not only utilize solar energy, but also provide protection from wind and rain.

[0003] Photovoltaic tile systems are usually installed and fixed using a bracket system. Traditional bracket systems are complex to install. Each photovoltaic module requires a large number of brackets and fasteners, and there are more than 10 places where fastening screws are required. If too many screws are used, there will be more leakage points, and water seepage is likely to occur. In addition, if screw holes are opened in the photovoltaic tiles, the photovoltaic tiles will be damaged with the screw holes as the center and spread to the surrounding areas, thereby reducing the service life of the photovoltaic tiles. Summary of the invention

[0004] In view of this, the present invention provides a photovoltaic tile roof to solve the problems of complex installation of the photovoltaic tile system, easy water seepage, and short service life of the photovoltaic tiles.

[0007] Among them, any two adjacent photovoltaic tile assemblies along the roof slope direction are parallel to each other, and the second frame of the relatively upper photovoltaic tile assembly is bonded to the top surface of the relatively lower photovoltaic tile assembly through a sealing structure.

[0008] Beneficial effects:

[0009] By fixedly connecting the lower end of the relatively upper photovoltaic tile assembly to the relatively lower photovoltaic tile assembly through the sealing structure of the second frame, the lower end of the relatively upper photovoltaic tile assembly and the upper end of the relatively lower photovoltaic tile assembly are stacked, and the relatively upper photovoltaic tile assembly can provide a pressing force to the relatively lower photovoltaic tile assembly, thereby ensuring the stability of the relatively lower photovoltaic tile assembly, and the photovoltaic tile assembly is fixedly connected to the roof through the first frame, and the photovoltaic tile assembly is installed in a manner that the upper end is fixed to the roof and the lower end is stacked on the photovoltaic tile assembly below, thereby avoiding the use of a bracket system and the opening of screw holes for installation, thereby improving installation efficiency, and at the same time, preventing leakage points and problems that affect the life of the photovoltaic tiles. The sealing structure at the bottom of the second frame is subjected to the force of the second frame and the top surface of the photovoltaic tile assembly, so that it is tightly connected to the second frame and the top surface of the photovoltaic tile assembly, thereby preventing rainwater from flowing to the roof and the connection between the first frame and the roof, and effectively achieving the effects of waterproofing and water diversion.

[0010] In an optional embodiment, the photovoltaic tile assembly has a plurality of interconnected photovoltaic tiles, and the photovoltaic tiles of two adjacent photovoltaic tile assemblies are staggered.

[0011] Beneficial effects:

[0012] The staggered arrangement enables the upper photovoltaic tile to provide a pressing force to the two lower photovoltaic tiles at the same time, thereby helping to improve the overall stability.

[0013] In an optional embodiment, a third frame or a fourth frame is provided on the side of the photovoltaic tile facing the adjacent photovoltaic tile, the third frame has a connecting piece, and the fourth frame is provided with a matching piece, and the connecting piece and the matching piece are detachably connected to make the third frame and the fourth frame detachably connected.

[0014] Beneficial effects:

[0015] Adjacent photovoltaic tiles are detachably connected through the third frame and the fourth frame, which is conducive to the installation and removal of photovoltaic tiles. When one or several photovoltaic tiles in the photovoltaic tile assembly are damaged, the damaged photovoltaic tiles can be removed and replaced without replacing the entire photovoltaic tile assembly, which is conducive to saving costs and avoiding waste of resources.

[0016] In an optional embodiment, the fourth frame is located above the third frame, the third frame has a first through slot opening upward, and the fourth frame has a second through slot opening downward, the first through slot and the second through slot are arranged opposite to each other, the first through slot and the second through slot are matched to form a connecting cavity, the connecting member and the mating member are respectively arranged in the first through slot and the second through slot, the connecting member is a slider, the width of the slider gradually increases from the bottom to the top, the mating member is a slide groove, the width of the slide groove gradually decreases from the top to the bottom, the slider can be slidably arranged in the slide groove, and the outer wall of the slider is gap-matched with the inner wall of the slide groove.

[0019] In an optional implementation, cavity covers are respectively provided at both ends of the third frame and the fourth frame, and the cavity covers are used to seal the connection cavity.

[0020] Beneficial effects:

[0021] The cavity cover can simultaneously close the openings at one end of the third frame and the fourth frame, and the cavity cover plays a role in sealing the connection cavity to prevent rainwater from flowing into the connection cavity.

[0022] In an optional embodiment, it also includes: a fixing buckle, one end of which has a slot, the slot is clamped with the lower ends of the third frame and the fourth frame, and the other end of the fixing buckle is bent toward the roof to form an abutment portion, and the abutment portion abuts against the tile hanging strip of the roof.

[0023] Beneficial effects:

The fixing buckles are beneficial to improving the stability and wind resistance of the photovoltaic tiles.

[0025] In an optional embodiment, a cushion block is provided between the fixing buckle and the top surface of the photovoltaic tile, and two ends of the cushion block are respectively bonded to the fixing buckle and the top surface of the photovoltaic tile.

[0029] Beneficial effects:

[0030] The cylindrical sealing strip has a cavity therein. When the cylindrical sealing strip is subjected to the force from the second frame and the top surface of the photovoltaic tile assembly, it will deform, thereby increasing the contact area with the top surface of the photovoltaic tile assembly and better improving the waterproof effect.
