[0034] The multi-faceted photovoltaic curtain wall bridge setting adopts the angle installation of the outer curtain wall glass 1 and the keel assembly. This structure is of great significance in the efficient use of solar energy and the increase of the function of the building exterior wall. By installing at a certain angle, the outer curtain wall glass 1 can block part of the light beam from directly irradiating into the room, thereby reducing the strong light irradiation in the room, especially in the hot and strong light period in summer, effectively reducing the problem of excessive indoor temperature. Such a design can significantly reduce the power consumption of air conditioning and achieve the purpose of energy saving. At the same time, when the external environment is weak, the outer curtain wall glass 1 can also play a role in supplementing indoor lighting, reducing the demand for lighting, and further reducing energy consumption. The advantage of this structure is that it balances the relationship between indoor comfort and energy consumption and realizes the sustainable use of energy. In addition, the multi-faceted photovoltaic curtain wall bridge setting has some other benefits. First, the structure makes the building exterior wall no longer a simple decoration, but has the function of solar power generation. Through the installation of the photovoltaic power generation system, under the condition of sufficient sunshine, solar energy can be used to generate electricity to achieve sustainable energy supply. Secondly, the multi-faceted photovoltaic curtain wall bridge setting can also increase the beauty and uniqueness of the building appearance and enhance the overall image of the building. In addition, the installation and maintenance management of this structure has become more convenient. The photovoltaic power generation system has a two-way communication connection with the main power unit, which can monitor and control the operating status of the photovoltaic curtain wall in real time. The main power unit can transmit current setting instructions to the photovoltaic curtain wall to ensure the normal operation of the photovoltaic power generation system. In addition, the photovoltaic curtain wall can also receive the status information of the tested lamps collected by the main power unit or various sensors, and adjust the working mode of the photovoltaic power generation system in time to ensure efficiency and safety.

[0035] A fixing plate 41 is installed on the side of the second vertical keel 4 close to the inner curtain wall glass, and the fixing plate 41 extends convex plates on both sides, which are used to fix the inner curtain wall glass 2 to the bottom of the horizontal keel 6. This design can ensure that the glass is firmly installed on the structure, increasing the stability and safety of the building. A groove in the shape of an inverted trapezoid is provided on the side of the second vertical keel 4 close to the inner curtain wall glass, and a corresponding fixing buckle is provided on the side of the fixing plate 41 close to the inner curtain wall glass, which is used to realize the installation of the fixing plate 41 and facilitate disassembly. This detachable structure makes maintenance and replacement of glass more convenient and quick.

[0036] In order to adapt to the horizontal keel 6, the second vertical keel 4 is provided with a limiting structure adapted to the horizontal keel 6, so that the second vertical keel 4 can be fixed in the correct position to ensure the accurate docking and stability of the entire system. In addition, the existence of the limiting structure can also provide additional support, increasing the strength and durability of the entire curtain wall system. The first vertical keel 3 and the second vertical keel 4 are both provided with a plurality of adhesive strips 13 on the side close to the curtain wall glass, wherein the top section of the first vertical keel 3 is a trapezoid, and the top section of the second vertical keel 4 is an inverted trapezoid. The adhesive strips 13 are installed on the waist, and the outer curtain wall glass 1 is placed on the top of the adhesive strips 13. This design mainly prevents the outer curtain wall glass from being in conflict with the curtain wall glass. At the same time, the outer curtain wall glass 1, as part of the curtain wall, can effectively isolate the external noise and temperature changes, providing a suitable indoor environment. In addition, the first vertical keel 3 and the second vertical keel 4 are both provided with a groove with a trapezoidal cross-section shape near the curtain wall glass side, and the lower surface of the rubber strip 13 is provided with a dovetail structure of a corresponding shape, and the inverted trapezoidal groove matches the corresponding dovetail structure on the lower surface of the rubber strip 13, and the dovetail structure is installed in the corresponding trapezoidal groove. In this way, the rubber strip 13 can be accurately positioned and firmly fixed. Through this design, the components of the entire photovoltaic curtain wall system can be closely connected to each other to ensure the stability and integrity of the system. In summary, the design ensures the stability, safety and functionality of the curtain wall system by considering a variety of details and usage scenarios. Each component is carefully designed to effectively prevent the keel component from colliding with the glass curtain wall when installing it, thereby avoiding damage to the glass curtain wall.

[0037] The utility model not only considers fixation and connection, but also pays attention to details and practicality. The utility model prevents the glass pressing plate 9 from colliding with the curtain wall glass, thereby causing damage, by setting a rubber strip. A glass pressing plate 9 is provided at the connection of the outer curtain wall glass 1, wherein the glass pressing plate 9 above the first vertical keel 3 is a positive angle, and the glass pressing plate 9 above the second vertical keel 4 is a negative angle. The two sides of the glass pressing plate 9 are installed on the edge top of the outer curtain wall glass 1 through the second rubber strip 14, which can effectively prevent the glass pressing plate 9 from colliding with the curtain wall glass and causing damage during the installation process. The glass pressing plate 9 is fixed to the side of the first vertical keel 3 or the second vertical keel 4 close to the outer curtain wall glass by a bolt 11, and a bolt soft rubber sheath 12 is provided on the outside of the bolt 11, which can prevent the bolt 11 from colliding during the installation process and causing damage to the glass. Such a structure enables the outer curtain wall glass 1 to be firmly connected to the top of the first vertical keel 3 or the second vertical keel 4. In addition to the functional aspects, the utility model also pays attention to the appearance design. A decorative cover plate 10 is provided on the side of the glass pressing plate 9 away from the glass, which is decorative. The top ends of the two sides of the decorative cover plate 10 protrude inward to form buckles, and a buckle connection method is adopted to ensure a tight connection and aesthetic effect. The two sides of the glass pressing plate 9 are recessed inward to form corresponding buckle grooves, so that the buckles can be firmly fixed together to prevent loosening, falling off or displacement. The detailed consideration of this curtain wall design gives the entire system multiple advantages. First, it provides reliable protection measures to ensure that the interior of the building is not disturbed by the external environment. Secondly, through the buckle connection method and soft rubber sheath, the system maintains the stability and durability of the structure. In terms of usage scenarios, the utility model can be widely used in high-rise buildings, commercial centers, hotels and other buildings that require large-area glass curtain walls.

[0038] A breathable safety net 7 is provided in the cavity of the hollow layer, and a breathable louver 8 is provided on the contact surface between the cavity of the hollow layer and the outside world. The breathable louver 8 can be opened, and the cavity temperature can be adjusted by opening and closing the breathable louver 8. In hot seasons, the principle of hot air rising upward is used to facilitate the upward discharge of hot air. The heat radiation of the inner curtain wall glass 2 by sunlight is reduced, and the energy consumption of air conditioning in summer is reduced; in winter, the louver is closed, and the cavity can store a certain amount of heat through the sunlight during the day, reducing the cold radiation of the outside cold air to the inner curtain wall glass 2 and improving the thermal insulation effect of the curtain wall.
