Mounting structure of assembled household photovoltaic carport and photovoltaic module on waterproof roof

[0001] Cross-reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202411317212.2, filed on September 20, 2024, entitled "Assembled household photovoltaic carport", and the Chinese patent application No. 202520455780.2, filed on March 13, 2025, entitled "Mounting structure of photovoltaic module on waterproof roof", the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0003] The present application relates to the field of photovoltaic power generation, in particular to a mounting structure of assembled household photovoltaic carport and photovoltaic module on waterproof roof. BACKGROUND

[0004] At present, the state policy supports photovoltaic power generation projects, and the construction scale of domestic photovoltaic power stations is continuously expanding. The types of photovoltaic power generation systems are gradually diversified. The photovoltaic carport is a system combining photovoltaic power generation and carport. It can not only provide shelter for vehicles, but also create clean photovoltaic energy for electric vehicle charging, lighting and grid connection. Especially in recent years, with the popularity of new energy electric vehicles, more and more families have the demand to install photovoltaic carports.

[0005] The structure of the current photovoltaic carport is heavy, and welding and other operations are required during installation. Family users need professional construction teams to install the photovoltaic carport during the installation process in their courtyards. The construction period is long, the construction process is complex, and the foot scaffold needs to be set up, which occupies a lot of space. For family users, it is a large-scale construction project, which is not conducive to the large-scale promotion of photovoltaic carports.

[0006] In addition, with the development of the photovoltaic industry, photovoltaic power stations have developed from centralized to distributed, especially in rural areas, photovoltaic modules need to be installed on the roof. However, the building roof in rural areas is mainly a gable roof. The existing installation method of photovoltaic modules is to install the four edges of the photovoltaic module on the support through a pressing block. Due to the existence of the pressing block, there is a gap between the photovoltaic module and other components, which leads to the fact that the roof module cannot form a complete waterproof system. Rainwater can reach the building roof through the gap. In addition, during the installation of the photovoltaic module, the tiles need to be removed, and the support needs to be installed, which is easy to damage the roof waterproof system, thereby affecting the waterproofness of the roof and the safety of the building.

Because the upper end surface of one first purlin 41 and one second purlin 42 is provided with one photovoltaic module 5, and the thickness of the first purlin 41 is smaller than the thickness of the second purlin 42; so that the angle between the photovoltaic module 5 and the horizontal plane is smaller than the angle between the beam profile 21 and the horizontal plane, so that the right lower end surface of the photovoltaic module 5 in the second direction is overlapped with the left upper end surface of the adjacent photovoltaic module 5 in the second direction, and the projection of the right end of the photovoltaic module 5 in the vertical direction falls at least partially on the left side of the adjacent photovoltaic module 5 in the second direction, that is, the overlapping part of the two adjacent photovoltaic modules 5 in the second direction overlaps each other, effectively avoiding rainwater entering the lower end surface of the photovoltaic assembly through the overlapping part of the two photovoltaic modules 5, and improving the waterproof performance.

In the present application, the connection between the upper and lower rows of photovoltaic modules 310 is connected by overlapping, and the sealing rubber strip 50 is arranged at the overlapping position, which can seal the photovoltaic mechanism 3 and prevent water leakage of the photovoltaic mechanism 3.

[0132] Further, as shown in FIG. 24, the plurality of columns of longitudinal photovoltaic modules 310 are connected by the cover plate 330, which is suitable for sealing the photovoltaic mechanism 3.
