Description

A photovoltaic curtain wall structure Technical Field

[0001] This application relates to the field of building-integrated photovoltaics (BIPV) technology, specifically a photovoltaic curtain wall structure. Background Technology

[0002] With the global push towards carbon neutrality, Building Integrated Photovoltaics (BIPV) has become a crucial direction in modern architectural design. Photovoltaic glass, as a core material in BIPV, is expanding its application from rooftops to building facades. By deeply integrating photovoltaic power generation with the building envelope, integrated design of energy self-sufficiency and building function is achieved. Effective smoke extraction systems are essential in public buildings to ensure life safety during fires. Especially in densely populated areas, the design of natural smoke extraction windows must balance functionality, concealment, and reliability. Ground-floor rooms in public buildings with a floor area greater than 100 square meters that are frequently occupied must be equipped with natural smoke extraction systems, with an effective smoke extraction area of ​​2%–5% of the floor area.

[0003] Traditional machining of photovoltaic glass curtain walls can damage their power generation units, making it impossible to directly install conventional operable windows. External smoke extraction equipment obstructs the sunlight-receiving surface of the photovoltaic panels, reducing power generation efficiency. Protruding smoke extraction windows or independent smoke extraction shafts disrupt the integrity of the building facade, conflicting with the aesthetic requirements of high-end commercial buildings, cultural landmarks, and other projects. Therefore, a photovoltaic curtain wall structure needs to be designed to solve these problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a photovoltaic curtain wall structure that solves the problem that photovoltaic glass curtain wall smoke exhaust windows or independent smoke exhaust wells damage the integrity of the building facade.

[0006] The technical solution adopted by this application to solve its technical problem is: a photovoltaic curtain wall structure, including a frame and a power-generating glass curtain wall, wherein the power-generating glass curtain wall is installed obliquely at the front end of the frame, and further includes a mounting frame, wherein the mounting frame is installed at the rear end of the frame and the power-generating glass curtain wall, and is adapted to support the power-generating glass curtain wall;

[0007] The connecting assembly includes a first connecting plate and a second connecting plate rotatably mounted on both sides of the mounting frame, adapted to connect the frame and the power-generating glass curtain wall;

[0008] An adjustment component is installed on one side of the power-generating glass curtain wall and is adapted to adjust the tilt angle of the power-generating glass curtain wall.

[0009] Furthermore, the adjustment assembly includes a sliding plate installed on one side of the power-generating glass curtain wall, with guide blocks fixed at both ends of the sliding plate. A guide groove is provided on one side of the power-generating glass curtain wall, and the guide blocks slide inside the guide groove to adjust the position of the sliding plate. The second connecting plate is bolted to the sliding plate to facilitate the installation connection between the mounting frame and the power-generating glass curtain wall.

[0010] Furthermore, two limiting plates are fixed on one side of the sliding plate, and a fastening bolt is connected to the middle of the limiting plate. Multiple connecting holes are opened inside the guide groove, and the fastening bolt is threaded into the connecting holes, which is suitable for limiting the sliding plate at different positions.

[0011] Furthermore, limit blocks are fixed on both sides of the guide block, and a limit groove is formed inside the guide groove. The limit block slides inside the limit groove, which is suitable for limiting the guide block.

[0012] Furthermore, a fixing plate is fixed to the rear end of the frame, and the fixing plate is connected to the first connecting plate by bolts, which is suitable for the installation connection between the frame and the mounting frame.

[0013] Furthermore, the frame and the power-generating glass curtain wall are installed at an angle between two floor slabs, forming a concealed cavity.

[0014] Furthermore, multiple curtain slats are installed inside the mounting frame.

[0015] The beneficial effects of this application are as follows: The photovoltaic curtain wall structure provided by this application, by tilting the power-generating glass and forming a concealed cavity, not only ensures the aesthetics of the building, but also realizes the smoke exhaust function, avoiding the damage to the building facade caused by traditional smoke exhaust windows or independent smoke exhaust wells, and meeting the high aesthetic requirements of high-end commercial buildings, cultural landmarks and other projects. The first and second connecting plates, which are rotatably installed on both sides of the mounting frame in the connecting components, can make the mounting frame rotate and adjust to support the power-generating glass curtain wall. Furthermore, the tilt angle of the power-generating glass curtain wall can be adapted to wind speed conditions and architectural shape requirements in different climate zones by adjusting the components.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] As shown in Figures 1-6, this application provides a photovoltaic curtain wall structure, including a frame 1, a power-generating glass curtain wall 2, a mounting frame 3, a connecting component, and an adjustment component.

[0029] Frame 1 serves as the fundamental supporting component of the entire photovoltaic curtain wall structure, with a fixing plate 7 fixed at its rear end. During actual installation, frame 1 is typically installed on the building structure between two floor slabs. The two triangular openings formed by the assembly of frame 1, the photovoltaic glass curtain wall 2, and the mounting frame 3 are sealed by the two floor slabs. The fixing plate 7 facilitates the connection between frame 1 and the connecting components. The connecting components include a first connecting plate 5 and a second connecting plate 6 rotatably mounted on both sides of the mounting frame 3. The fixing plate 7 is connected to the first connecting plate 5 in the connecting components via bolts, achieving a stable installation connection between frame 1 and the mounting frame 3.

[0030] The photovoltaic glass curtain wall 2 is installed at an angle at the front end of the frame 1. It not only has the enclosure function of a regular curtain wall, but also provides electricity to the building through photovoltaic power generation. A guide groove 9 is provided on one side of the photovoltaic glass curtain wall 2 to adjust the tilt angle in conjunction with the adjustment components.

[0031] The mounting frame 3 is installed at the rear end of the frame 1 and the power-generating glass curtain wall 2, mainly to support the power-generating glass curtain wall 2. Multiple slats 4 are installed inside the mounting frame 3. Under normal circumstances, these slats 4 can provide a shielding function to enhance the privacy of the building interior. These slats 4 form a louver, which also provides ventilation and can be used to maintain the facade design and prevent mosquitoes.

[0032] The first connecting plate 5 is connected to the fixing plate 7 at the rear end of the frame 1 by bolts, thus connecting the frame 1 to the mounting frame 3; the second connecting plate 6 is connected to the sliding plate 8 in the adjustment assembly by bolts, thus connecting the mounting frame 3 to the power-generating glass curtain wall 2. Since the first connecting plate 5 and the second connecting plate 6 are rotatably installed on both sides of the mounting frame 3, the mounting frame 3 can be rotated and adjusted to a certain extent, thereby flexibly supporting the power-generating glass curtain wall 2 and adapting to different installation requirements and stress conditions.

[0033] An adjustment assembly is installed on one side of the power-generating glass curtain wall 2 to adjust its tilt angle. The adjustment assembly mainly consists of a sliding plate 8, guide blocks 10, limiting plates 13, fastening bolts 14, and connecting holes 15. The sliding plate 8 is installed on one side of the power-generating glass curtain wall 2, with guide blocks 10 fixed at both ends. The guide blocks 10 are adapted to guide grooves 9 on one side of the power-generating glass curtain wall 2, and slide within the guide grooves 9 to adjust the position of the sliding plate 8. To ensure the stability and accuracy of the guide blocks 10 during sliding, limiting blocks 12 are fixed on both sides of the guide blocks 10. A corresponding limiting groove 11 is formed inside the guide groove 9, and the limiting blocks 12 slide within the limiting grooves 11, limiting the guide blocks 10 and preventing them from shifting or disengaging from the guide grooves 9 during sliding.

[0034] Two limiting plates 13 are fixed to one side of the sliding plate 8, and fastening bolts 14 are connected to the middle of the limiting plates 13. Multiple connecting holes 15 are formed along the length of the guide groove 9. When the sliding plate 8 slides to a suitable position in the guide groove 9 via the guide block 10, the fastening bolts 14 are threaded into the corresponding connecting holes 15, thereby limiting the sliding plate 8 at different positions and allowing the power-generating glass curtain wall 2 to be fixed at the required tilt angle. Construction workers can loosen the fastening bolts 14 and change the tilt angle of the power-generating glass curtain wall 2 by sliding the sliding plate 8. After adjustment, the fastening bolts 14 are tightened again for fixation. When there are special requirements for the building's shape, the tilt angle of the power-generating glass curtain wall 2 can also be flexibly adjusted in the above manner.

[0035] Furthermore, the frame 1 and the power-generating glass curtain wall 2 are installed at an angle, overlapping each other between the two floor slabs, creating a concealed space. This concealed cavity can serve as a decorative structure on the building's facade, enhancing its overall aesthetics. In the event of a fire, the concealed cavity can act as a natural smoke exhaust channel, allowing hot smoke to be expelled outdoors, thus achieving smoke extraction. This avoids the damage to the building facade caused by traditional smoke exhaust windows or independent smoke exhaust shafts, meeting the high aesthetic requirements of high-end commercial buildings, cultural landmarks, and other projects.

[0036] Working Principle: When installing the photovoltaic curtain wall structure, first install the frame 1 at the designated location on the building, ensuring its stability and reliability. Next, connect the first connecting plate 5 to the fixing plate 7 at the rear end of the frame 1 using bolts, initially connecting the mounting frame 3 to the frame 1. Then, align the guide block 10 on the sliding plate 8 with the guide groove 9 on one side of the power-generating glass curtain wall 2, and insert the guide block 10 into the guide groove 9. At this time, the limiting blocks 12 on both sides of the guide block 10 will fall into the limiting groove 11. Finally, connect the second connecting plate 6 to the sliding plate 8 using bolts, completing the connection between the mounting frame 3 and the power-generating glass curtain wall 2.

[0037] During installation, when adjusting the tilt angle of the power-generating glass curtain wall 2, the installers loosen the fastening bolts 14, allowing the sliding plate 8 to slide freely within the guide groove 9. Because the guide block 10 slides within the guide groove 9, and the limiting block 12 acts as a limit within the limiting groove 11, the sliding plate 8 can only slide smoothly along the direction of the guide groove 9, thereby causing the power-generating glass curtain wall 2 to rotate around the connection point with the mounting frame 3, thus adjusting the tilt angle. Once the power-generating glass curtain wall 2 is adjusted to the appropriate tilt angle, the installers tighten the fastening bolts 14, ensuring their threads are installed in the corresponding connection holes 15, thereby fixing the position of the sliding plate 8 and ultimately securing the power-generating glass curtain wall 2 at the desired tilt angle.

[0038] In the event of an emergency such as a fire during the building's use, the curtain slats 4 inside the mounting frame 3 can form louvers, which take into account both the exterior facade design and the prevention of mosquitoes and insects. Hot smoke can enter the concealed cavity through the gap between the mounting frame 3 and the power-generating glass curtain wall 2, and then use the concealed cavity as a smoke exhaust channel to exhaust the hot smoke outdoors, ensuring the safety of people inside the building.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
