Technical Field

[0001] The present invention relates to the technical field of new energy buildings, in particular to a photovoltaic roof tile assembly. Background Art

[0002] Photovoltaic roof tile assemblies are integrated solar cells into building roof tiles, combining the protective functions of traditional roof tiles with the photovoltaic power generation capabilities. They are widely used on rooftops of residential, commercial, and agricultural facilities. By replacing traditional tiles, they achieve green energy goals such as self-generation, thermal insulation, and energy conservation, making them a key component of energy conservation and emission reduction initiatives.

[0003] The photovoltaic roof tile assembly in the existing technology lacks a reliable frame assembly, is inconvenient to assemble, and has insufficient structural strength. It is also impossible to assemble it according to the width of the actual installation site. Some existing roof tile assemblies have an imperfect drainage system and large gaps between the panels, which makes the sunshade and rain shelter effect less than ideal. In addition, during daily use, the adhesion of debris such as dust or bird droppings will affect the amount of light entering the photovoltaic assembly. For this reason, we propose a photovoltaic roof tile assembly. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a photovoltaic roof tile assembly with a reliable frame support unit. The number of horizontal splicing of the middle connecting block and the support frame can be adjusted according to the actual width requirements to adjust the width of the final roof tile; the components are fastened with bolts on the basis of plug-in and card-jointing, which facilitates assembly and improves the stability of the photovoltaic roof support frame; the frame as a whole adopts a triangular stable structure with good structural stability; and it has a reliable paving water guide unit, and the drainage trough has the function of drainage and is also used for the installation of the bracket and the photovoltaic panel body. The mounting bracket is fastened by the card on both sides thereof. The side span is connected between two adjacent drainage channels, and the chamfered structure at the edge is more conducive to the collection of rainwater into the drainage channel; and the entire photovoltaic roof slope has good tightness, which can achieve good sunshade and rain shelter effects; it also has a reliable tile surface cleaning unit. Under the action of the power device, the movable frame will drive the lower cleaning component to move along the inclined photovoltaic roof. When the drum rotates, the silicone strip on its outside will clean the inclined surface of the photovoltaic component. By spraying clean water on the silicone strip, the cleaning effect can be improved, thereby ensuring its light intake, and avoiding dust or bird droppings from having an adverse effect on the light intake of the photovoltaic panel, which can effectively solve the problems in the background technology.
