[0024] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the embodiments described are only a portion of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, in some illustrative embodiments, a photovoltaic building curtain wall is provided, which combines solar photovoltaic technology with traditional building curtain walls, not only providing external packaging and decoration for the building, but also generating electricity from solar energy, thereby increasing the energy self-sufficiency of the building and helping to reduce carbon emissions.

[0026] The photovoltaic building curtain wall of this embodiment specifically includes: glass panels 1, curtain wall keels, and a photovoltaic system. The curtain wall keels are connected to the main structure of the building and serve as a support for the installation of the glass panels. The bracket portion of the photovoltaic system is integrated into the curtain wall keels, using a combination of embedded and external structures to provide stable load-bearing and support functions. The curtain wall keels include: vertical curtain wall keels, and the vertical curtain wall keels are composed of two symmetrically arranged C-shaped frames 2. The two C-shaped frames 2 can be connected and reinforced with crossbeams, or they can be arranged side by side and connected to the main structure of the building, supplemented by transverse keels.

[0027] The photovoltaic system includes: a photovoltaic panel bracket, solar panels 3, a DC combiner box 4, an inverter 5, and a front-end monitoring box 6. The input of the DC combiner box 4 is connected to the output of the solar panel 3 via photovoltaic cables. The DC combiner box 4 is used to collect the DC power generated by the solar panel 3 and combine multiple DC power channels into one or more channels. It also measures and protects current and voltage. The inverter 5 is connected to the output of the DC combiner box 4 and converts the DC power into AC power that can be used by other devices. The front-end monitoring box 6 is equipped with a sensor group, such as a temperature sensor, a light sensor, and a wind speed sensor, to detect environmental data around the solar panel 3.

[0028] The photovoltaic panel bracket is used to support the solar panel 3 and consists of an embedded frame 7 and an external suspension 8. The embedded frame 7 is part of the vertical keel of the curtain wall and is arranged between the two C-shaped frames 2. The external suspension 8 is arranged on the outer panel of the embedded frame 7; the embedded frame 7 provides stable load-bearing and support functions, while the design of the external suspension 8 increases the overall stability and wind pressure resistance. The embedded frame 7 is a rectangular columnar structure with a hollow interior. The rectangular columnar structure is a common geometric shape. The main feature of this structure is that it has a rectangular cross-section, usually in the shape of a cuboid, which achieves weight reduction and has sufficient strength. Preferably, a reinforcing plate 701 is provided at the inner wall corner of the embedded frame 7 to enhance the anti-deformation ability of the photovoltaic panel bracket.

[0029] The external suspension 8 comprises a lower oblique support column 801, an upper oblique support rod 802, a base 803, and a plurality of pre-tensioning ribs 804. The inner end of the lower oblique support column 801 is connected to the outer panel of the embedded frame 7, and the upper oblique support rod 802 is disposed at the outer end of the lower oblique support column 801, so that the lower oblique support column 801 and the upper oblique support rod 802 form an angle, and the angle a between the lower oblique support column 801 and the upper oblique support rod 802 satisfies the following conditions: 70°≤a≤90°.

[0030] The oblique lower support column 801 is a truncated cone structure, and the oblique upper support rod 802 is a cylindrical structure, which improves the load-bearing capacity and stability of the structure and can effectively withstand external loads. The truncated cone and cylindrical structures have high rigidity and can resist bending and twisting, ensuring that the shape of the structure remains unchanged when subjected to stress.

[0031] The base 803 is arranged on the top of the inclined upper support rod 802, the solar panel 3 is arranged on the base 803, and a weight-reducing avoidance hole 807 is opened on the base 803. The base 803 is a rectangular plate structure. The rectangular plate structure can provide good stability and rigidity, and is suitable for occasions that need to withstand large pressure or torsional forces. X-shaped reinforcement ribs 805 are arranged on the back of the base 803, which can further increase the stability and bearing capacity of the base 803. The X-shaped ribs increase the bending stiffness of the structure by providing support in different directions. There are four pre-tensioning ribs 804, and they are all connected to the outer end of the X-shaped reinforcement rib 805. The inner end of the pre-tensioning rib 804 is connected to the position where the inclined lower support column 801 and the inclined upper support rod 802 are connected. This connection method can effectively transmit the tightening force to the entire structure, thereby enhancing the dynamic stability and static bearing capacity of the entire machine.

[0032] A tensioning sleeve 806 is provided at the junction of the oblique lower support column 801 and the oblique upper support rod 802. The oblique lower support column 801, the oblique upper support rod 802 and the tensioning sleeve 806 are an integrally formed structure. The inner end of the pre-tensioning rib 804 is connected to the tensioning sleeve 806, and the outer end of the pre-tensioning rib 804 is connected to the X-shaped reinforcement rib 805. An integrally formed structure means that these components are formed at one time during the manufacturing process, without the need for subsequent assembly steps. This can reduce the number of parts, simplify the structure, reduce manufacturing costs, and improve the rigidity and stability of the structure. Moreover, the above structural design can ensure that the tightening force is evenly distributed, thereby improving the strength and stability of the connection. The tensioning sleeve 806, as a connecting component, can effectively transmit tension while maintaining the compactness and rigidity of the connection, so that the entire structure can better withstand pressure and bending when subjected to load, thereby improving the overall load-bearing capacity and service life.

[0033] Front-end monitoring box 6 is mounted within embedded frame 7, which has a monitoring window 702 formed therein. Monitoring window 702 is positioned above external suspension 8, and the sensor group's probe is positioned within monitoring window 702. By embedding the monitoring box within the frame, space can be effectively utilized, reducing the overall volume of the structure. This is particularly suitable for applications where space is limited. It also improves the safety of the equipment and reduces the impact of the external environment on the equipment, such as preventing dust and water.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
