[0033] The technical solution of the utility model is further described below in conjunction with specific implementation methods:

[0034] like Figure 1As shown, a photovoltaic building integrated unit enclosed snap-on thermal insulation facade structure includes a solar photovoltaic system and a thermal insulation force system. The thermal insulation force system includes a keel frame, an inner support plate 11, an inorganic thermal insulation material layer 10, a windproof and waterproof air-blocking plate 9 and a U-shaped steel 5 bracket. The inner support plate 11 is installed inside the keel frame to fix the inorganic thermal insulation material layer 10 above, and the windproof and waterproof air-blocking plate 9 and the U-shaped steel 5 bracket are installed on the outside of the inorganic thermal insulation material layer 10 in sequence. The solar photovoltaic system is installed on the thermal insulation force system through the U-shaped steel 5 bracket. The inorganic thermal insulation material layer 10, the windproof and waterproof air-blocking plate 9, and the glass fiber polyurethane keel frame in the thermal insulation force system work together to significantly improve the thermal insulation performance, effectively reduce indoor heat loss, and prevent the penetration of external hot and cold air, thereby ensuring the comfort of the indoor environment, reducing the dependence on air conditioning or heating systems, and further reducing energy consumption.

[0035] The solar photovoltaic system includes a photovoltaic panel 4, a photovoltaic panel outer gusset plate 1, a photovoltaic panel fixing frame 2, a solar controller and a cable box. The photovoltaic panel 4 is fixed to the photovoltaic panel fixing frame 2 through the photovoltaic panel outer gusset plate 1, and the photovoltaic panel 4 is connected to the solar controller through the cable in the cable box. Auxiliary equipment such as the solar controller and wiring are installed at the controller reel 12. The cable box is placed at the four corners of the photovoltaic panel 4, which is convenient for connecting multiple photovoltaic panels 4 and for maintenance and replacement of accessories. Because the photovoltaic panel 4 is relatively light as a whole, it can be carried and installed by several people without cranes or scaffolding, and dry installation can be fully realized. The solar photovoltaic system can convert sunlight energy into electrical energy, providing a sustainable source of electricity for buildings.

[0036] A cushion material 3 is provided at the connection between the photovoltaic panel outer buckle plate 1 and the photovoltaic panel fixing frame 2 to stabilize the photovoltaic panel 4.

[0037] The photovoltaic panel 4, the inorganic thermal insulation material layer 10 and other building components are all prefabricated and assembled in the factory. The prefabricated components can be assembled on the construction site quickly and in a manner similar to building blocks, which greatly improves the efficiency of the construction.

[0038] The keel frame is assembled from glass fiber polyurethane primary and secondary keels 13 and 7. Since the overall frame of the facade structure does not have the main load-bearing function, the thickness of the keel frame wall can be kept consistent. After all installations are completed, the interior can be decorated as a whole, painted, and the wall surface can be smoothed. The glass fiber polyurethane primary and secondary keels are insulating materials. Combined with the inorganic insulation material layer 10 and the windproof and waterproof air-blocking board 9, they can minimize the range of thermal bridges and avoid thermal bridge losses caused by irregular on-site construction in the later stage. All can be prefabricated in the factory, which is convenient to install and easy to replace.

[0039] Steel gaskets 8 are arranged inside the primary and secondary keels of glass fiber polyurethane to increase the keel strength when the components are connected and to prevent the keel from cracking.

[0040] like Figure 2 As shown, the U-shaped steel 5 bracket includes screws 14, bolts and two U-shaped steels 5. The two U-shaped steels 5 are fixed to the glass fiber polyurethane main keel 13 by screws 14 to form a ventilation layer 6. The photovoltaic panel fixing frame 2 in the solar photovoltaic system is fixed to the U-shaped steel 5 by bolts. The U-shaped steel 5 bracket is used to install the photovoltaic panel fixing frame 2, and a ventilation layer 6 is left between the U-shaped steel 5 bracket and the insulation material layer, which can better prevent condensation and isolate the heat of the photovoltaic panel. In addition, the combination with the insulation material can also achieve a good sound insulation effect and create a quiet indoor environment.

[0041] In summary, this photovoltaic building integrated unit enclosed snap-on insulation facade construction technology brings the following key advantages:

[0042] Environmental benefits: By converting solar energy into electricity, the system reduces dependence on traditional energy sources and significantly reduces carbon emissions.

[0043] Enhanced insulation: Advanced insulation technology effectively reduces a building’s energy needs, especially in extreme climate conditions, reducing heating and cooling expenses.

[0044] Economic benefits: The system can save users a lot of electricity and heating costs in the long term. Combined with the green energy incentives provided by the government, its economic benefits are particularly outstanding.

[0045] Design and Space Optimization: The integrated design solution saves space while providing the building with a modern and aesthetically pleasing appearance.

[0046] Stable energy supply: Insulation materials ensure stable indoor temperature in bad weather, further reducing energy consumption.

[0047] Added Building Value: The introduction of this technology can enhance the market value and attractiveness of a building.

[0048] Simplified maintenance: The assembled design simplifies installation and future maintenance, especially the external wire box design that is easy to inspect.
