Description

Technical Field

[0001] This utility model relates to the field of photovoltaic curtain wall technology, specifically a photovoltaic curtain wall with a concealed internal maintenance structure. Background Technology

[0002] Building-integrated photovoltaics (BIPV) systems are a new concept in photovoltaic power generation, representing a perfect combination of solar photovoltaic systems and modern architecture. In building design, photovoltaic modules are installed on the exterior surface of the building structure to provide electricity, integrating the solar power generation system with roofs, skylights, curtain walls, and other architectural elements. The construction of green and environmentally friendly buildings is experiencing a new surge globally. Solar photovoltaic power generation directly converts sunlight into electricity. While its applications span various industries, its greatest impact is on the building materials and construction sectors. In the 1990s, with rising costs of conventional power generation and increasing emphasis on environmental protection, some countries began using rapidly decreasing solar energy in buildings. Solar cells are now flexible, rollable, and only a few wavelengths thick, making them easy to cut, install, weatherproof, clean, and safe. They can replace architectural paints, ceramic tiles, and expensive curtain wall glass, serving as an exterior cladding material for energy-efficient walls.

[0003] A search revealed Chinese patent application CN202210391284.6, which discloses a photovoltaic (PV) curtain wall support assembly and a PV curtain wall. The assembly includes two C-shaped clamps and embedded parts. The embedded parts have internal threaded grooves on their inner walls. The two C-shaped clamps are symmetrically spaced, and a PV curtain wall assembly is positioned between them. A bottom support plate is connected to the bottom of both C-shaped clamps, and an upper connecting plate is fixedly connected to the top of the two C-shaped clamps. A connecting mechanism is provided on the mounting base corresponding to each second slot. This PV curtain wall provides robust support during use and features energy absorption protection. When subjected to external impacts, it effectively absorbs and buffers the forces, minimizing damage and ensuring normal power generation. This also extends the lifespan of the PV curtain wall.

[0004] The above technical solutions still have shortcomings:

[0005] Similar to traditional photovoltaic (PV) curtain walls, maintenance after installation often requires disassembling external components or using complex external equipment. This is not only cumbersome and time-consuming, but also prone to damaging the appearance of the PV curtain wall during maintenance, affecting the overall aesthetics of the building. Furthermore, external maintenance methods may be limited by environmental factors (such as severe weather and building height), increasing the difficulty and risk of maintenance. Therefore, we need to propose a PV curtain wall with a concealed internal maintenance structure. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A photovoltaic curtain wall with a concealed internal maintenance structure includes:

[0029] Main structure; The main structure includes a frame 1 and a photovoltaic glass panel 3. The frame 1 is arranged in a grid shape and has notches 2 distributed on it. The photovoltaic glass panel 3 is installed inside the notches 2. A control box is installed on the photovoltaic glass panel 3, and adjacent photovoltaic glass panels 3 are connected together by wires.

[0030] The inner wall of the notch 2 is provided with a mounting groove 4. Threaded holes 5 are provided at the four corners of the inner wall of the mounting groove 4. A threaded rod 7 is installed inside the threaded hole 5, and a handle 8 is provided at the end of the threaded rod 7. Each of the four corners of the photovoltaic glass panel 3 has a horizontal notch 6. The threaded rod 7 passes through the notch 6 and is threaded into the threaded hole 5. The handle 8 abuts against the photovoltaic glass panel 3. The notches 6 on the photovoltaic glass panel 3 are all horizontally oriented, allowing the horizontal handle 8 to pass through.

[0031] This utility model features a main structure comprising a frame 1 and a photovoltaic glass panel 3. The frame 1 has a notch 2 for mounting the photovoltaic glass panel 3, and the notch 2 has a mounting groove 4 with a threaded hole 5. A threaded rod 7 with a handle 8 is threaded into the threaded hole 5. The photovoltaic glass panel 3 has a notch 6. In actual use, after the embedded parts are installed on the exterior of the building, the frame 1 with the photovoltaic glass panel 3 is fixed by the embedded parts. When it is necessary to disassemble and repair the photovoltaic glass panel 3, the handle 8 is rotated to detach the handle 8 from the surface of the photovoltaic panel and rotated to the side, so that the photovoltaic glass panel 3 can be removed for inspection, maintenance or replacement.

[0032] When it is necessary to install the photovoltaic glass panel 3, insert the horizontally placed handle 8 corresponding to the notch 6 of the photovoltaic panel into the mounting groove 4, rotate the handle 8 until the handle 8 presses against and fits against the photovoltaic glass panel 3 to lock the photovoltaic glass panel 3. At this time, the handle 8 can be in any direction other than the notch 6.

[0033] In summary, this device has a simple structure and is easy to use. Through the cooperation of the notch 6 and the threaded rod 7 with the handle 8, it is easy to securely install the photovoltaic glass panel 3. It is also easy to disassemble from the inside for inspection and replacement of the photovoltaic glass panel 3. It can quickly separate from the frame 1 and accurately reset during installation, improving maintenance efficiency and safety.

[0034] For further details, please refer to Figure 3-4 :

[0035] A limiting block is provided at the end of the threaded rod 7, and a cavity is provided in the inner cavity of the threaded hole 5 for the limiting block to move, which can prevent the threaded rod 7 from falling out of the threaded hole 5. At the same time, since the threaded rod 7 and the handle 8 form an L-shaped structure, even if the threaded rod 7 becomes loose during long-term use, the handle 8 will remain in a vertical state due to gravity and will not be able to detach from the horizontal notch 6 on the photovoltaic glass panel 3, thereby avoiding the problem of the photovoltaic glass panel 3 falling off and having better safety and reliability.

[0036] In addition, please see Figure 1-5 :

[0037] The mounting groove 4 has a square-shaped sealing groove 9 inside. A sealing strip 10 is provided on the contact surface between the photovoltaic glass panel 3 and the mounting groove 4, and the sealing strip 10 is compatible with the sealing groove 9.

[0038] Through the cooperation of the sealing groove 9 and the sealing strip 10, a high degree of sealing can be achieved between the mounting groove 4 and the photovoltaic glass panel 3 when installing the photovoltaic glass panel 3.

[0039] Additionally, please see Figure 1 , 2 And 5:

[0040] The frame 1 has protruding edges 11 on two adjacent sides and concave edges 12 on two other adjacent sides. The protruding edges 11 and concave edges 12 are adapted to splice two adjacent sets of frames 1, and positioning holes 13 are provided on the protruding edges 11 and concave edges 12 respectively.

[0041] By setting a protruding edge 11 and a concave plate on the frame 1, it can play a good positioning role when assembling adjacent frames 1, making the connection between adjacent frames 1 tighter. The through holes on the protruding edge 11 and the concave plate can be used to insert embedded parts and fix them to the building facade.

[0042] In general, the adjacent frame 1, photovoltaic glass panel 3 and frame 1 are all installed in a modular assembly manner. The modules are connected by standardized connecting parts, which facilitates disassembly and replacement. This allows the modules to be installed and disassembled quickly without damaging the overall structure of the curtain wall, greatly simplifying the replacement and maintenance process.

[0043] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
