Description

Technical Field

[0001] This invention relates to the field of photovoltaic curtain wall technology, specifically a photovoltaic curtain wall that generates heat through photovoltaic power generation. Background Technology

[0002] Against the backdrop of a global push for low-carbon energy transition and the construction industry's pursuit of green development, building-integrated photovoltaics (BIPV) technology has gradually become a key development direction in the field of building energy conservation. Photovoltaic curtain walls, as an important practical application of this technology, are increasingly being used in various commercial and public buildings and high-rise residential buildings due to their comprehensive advantages of integrating building envelope, aesthetic decoration, and solar power generation. These curtain walls, by integrating photovoltaic power generation components with the traditional curtain wall structure, can directly convert solar energy into electricity for the building's interior, effectively reducing the building's consumption of traditional grid energy.

[0003] A photovoltaic power generation curtain wall, as proposed in authorization announcement number CN217759436U, includes: a glass assembly composed of several photovoltaic power generation glass panels; solar cells disposed on the glass assembly; a frame disposed around the glass assembly; and a lighting module disposed on the frame and connected to the solar cells. This power generation curtain wall integrates photovoltaic glass, enabling the curtain wall to generate electricity.

[0004] However, existing curtain walls generally face significant challenges in cleaning and maintenance after long-term use. Because curtain walls are exposed to the outdoor environment, dust, floating particles, and various pollutants easily accumulate on their surfaces. This not only damages the overall appearance of the building but also severely obstructs sunlight, reducing the light transmittance of photovoltaic modules and consequently leading to a significant decrease in power generation efficiency. Currently, the industry primarily uses manual suspended cleaning methods for curtain walls. This method requires workers wearing protective equipment to be suspended from the building's exterior wall to manually wipe it, posing a high risk of falls from heights and posing considerable danger. To overcome the difficulty of cleaning existing curtain walls, we offer a photovoltaic curtain wall that generates heat through photovoltaic power generation. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic curtain wall that generates heat through photovoltaic power generation, in order to solve the problems mentioned in the background art.

A suction component is provided on the inner wall of the hollow frame to drive the first and second actuating plates to move towards the inner wall of the hollow frame, thereby causing the sealing ring to expand. A locking component is provided on each rotating column to lock the position of the flip frame.

[0007] As a further aspect of the present invention, mounting holes are provided at all four corners of the hollow frame.

[0008] As a further embodiment of the present invention: the photoelectric component includes a positioning frame, the positioning frame is fixedly connected to the middle of the inner wall of the flip frame, a power generating glass is fixedly connected to one side of the positioning frame, and a heating glass is fixedly connected to the other side of the positioning frame.

[0009] As a further embodiment of the present invention: the sealing ring includes an elastic sealing ring, which is disposed between the first actuating plate and the second actuating plate. The elastic sealing ring is fixedly connected to the first actuating plate and the second actuating plate respectively. A central through hole is provided at both the upper and lower ends of the elastic sealing ring. The central through hole is sleeved on the rotating column. The inner side of the elastic sealing ring is an arc shape that matches the sealing ring groove.

[0010] As a further embodiment of the present invention: the elastic sealing ring is provided with side protrusions on both sides, and the side protrusions are slidably connected to the inner wall of the hollow frame.

[0011] As a further embodiment of the present invention: each of the four corners of the elastic sealing ring is provided with a limiting strip, the two ends of the limiting strip are respectively fixedly connected to the first actuating plate and the second actuating plate, and each limiting strip is provided with a tension spring, the two ends of the tension spring being fixedly connected to the first actuating plate and the second actuating plate respectively.

[0012] As a further embodiment of the present invention: the limiting component includes an outer sleeve, the outer sleeve is fixedly connected to the inner wall of the hollow frame, a positioning inner post is slidably connected inside the outer sleeve, a limiting slip ring is fixedly connected to one end of the positioning inner post that passes through the outer sleeve, a return spring is installed between the positioning inner post and the inner wall of the outer sleeve, and the end of the positioning inner post away from the outer sleeve is fixedly connected to the corresponding first action plate and second action plate respectively.

[0013] As a further embodiment of the present invention: the attraction component includes an electromagnet, which is fixedly connected to both ends of the hollow frame near the first actuating plate and the second actuating plate, and iron parts matching the electromagnet are fixedly connected to both ends of the first actuating plate and the second actuating plate.

[0014] As a further embodiment of the present invention: the locking assembly includes a fixing ring, which is fixedly connected to the rotating column at the position between the second actuating plate and the inner wall of the hollow frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention provides a rotation center for the flip frame by setting a rotating column, so that when the exterior wall needs to be cleaned, the power-generating glass on the exterior wall can be directly rotated to the interior, so that cleaning can be carried out from the interior. This avoids the problem of high danger of traditional curtain wall suspended cleaning. At the same time, the power-generating glass can convert solar energy into electrical energy to supply the building interior, reducing the power consumption of the power grid. In addition, the heating glass can generate heat in winter to increase the indoor temperature and improve indoor comfort.

[0017] 2. The present invention, through the setting of suction component and limiting component, can expand the elastic sealing ring when the flip frame needs to be flipped. After expansion, the elastic sealing ring disengages from the sealing ring groove. At the same time, the second action plate, while driving the elastic sealing ring to expand, will unlock the locking component and release the lock on the rotating column. At this time, the flip frame can be flipped smoothly, making it convenient to flip the power generation glass indoors for cleaning. When the flip frame is fixed, the elastic sealing ring will be embedded in the sealing ring groove. At the same time, the locking component ensures the stability of the flip frame. Furthermore, the elastic sealing ring embedded in the sealing ring groove can also ensure the sealing of the flip frame. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 In this embodiment of the invention, a photovoltaic curtain wall that generates heat through photovoltaic power generation includes a hollow frame 1, and mounting holes 2 are provided at each of the four corners of the hollow frame 1; the mounting holes 2 facilitate the installation of the hollow frame 1 onto the curtain wall keel.

[0032] Please see Figure 1 , Figure 2 and Figure 5 The hollow frame 1 has an installation opening 4 in the middle, and a flip frame 12 is provided inside the installation opening 4. Rotating columns 11 are fixedly connected to the middle of the upper and lower ends of the flip frame 12. The ends of the rotating columns 11 away from the flip frame 12 are rotatably connected to the hollow frame 1. The flip frame 12 is rotatably connected to the hollow frame 1 through the rotating columns 11, which enables the flip frame 12 to be flipped, making it easy to flip during subsequent cleaning. A photoelectric component 3 is provided inside the flip frame 12. The photoelectric component 3 includes a positioning frame 301, which is fixedly connected to the middle of the inner wall of the flip frame 12. A power-generating glass 303 is fixedly connected to one side of the positioning frame 301, and a heating glass 302 is fixedly connected to the other side of the positioning frame 301. The power-generating glass 303 can convert solar energy into electrical energy to supply the building interior, reducing the power consumption of the power grid. At the same time, the heating glass 302 can generate heat in winter, increasing the indoor temperature and improving indoor comfort.

[0033] Please see Figure 3 , Figure 4 , Figure 8 and Figure 9The hollow frame 1 has a first actuating plate 9 slidably connected to both sides inside, and a second actuating plate 10 slidably connected to both the upper and lower ends of the hollow frame 1. The second actuating plate 10 has a clearance hole 14 in the middle, which is fitted onto the rotating column 11. The outer surface of the flipping frame 12 has a sealing ring groove 13. A sealing ring 7, which mates with the sealing ring groove 13, is provided between the first actuating plate 9 and the second actuating plate 10. The sealing ring 7 includes an elastic sealing ring 701, which is located between the first actuating plate 9 and the second actuating plate 10. The elastic sealing ring 701 is respectively connected to the first actuating plate 9 and the second actuating plate 10. 0. Fixed connection. The elastic sealing ring 701 has a central through hole 704 at both the upper and lower ends. The central through hole 704 is sleeved on the rotating column 11. The inner side of the elastic sealing ring 701 is an arc shape that matches the sealing ring groove 13. The elastic sealing ring 701 can be embedded in the sealing ring groove 13 to seal the edge of the flip frame 12 and ensure the sealing performance of the structure. At the same time, the inner side of the elastic sealing ring 701 is an arc shape that matches the sealing ring groove 13. After the elastic sealing ring 701 is embedded in the sealing ring groove 13, it can not only seal but also assist the locking component 8 in limiting the flip frame 12 and ensuring the stability of the flip frame 12 when it is fixed.

[0034] Please see Figure 8 and Figure 9 The elastic sealing ring 701 has side protrusions 702 on both sides, which are slidably connected to the inner wall of the hollow frame 1. Each of the four corners of the elastic sealing ring 701 has a limiting stop 705, with both ends of the limiting stop 705 fixedly connected to the first actuating plate 9 and the second actuating plate 10 respectively. Each limiting stop 705 contains a tension spring 703, with both ends of the tension spring 703 fixedly connected to the first actuating plate 9 and the second actuating plate 10 respectively. The side protrusions 702 ensure that the elastic sealing ring 701 fits snugly against the inner wall of the hollow frame 1, guaranteeing a tight seal. Simultaneously, the tension springs 703 apply tension to the corners of the elastic sealing ring 701, ensuring that the corners also fit tightly against the corners of the flip frame 12, guaranteeing a tight seal at the corners.

[0035] Please see Figure 2 and Figure 7Limiting components 5 are provided at both ends and in the middle of the first action plate 9 and at both ends of the second action plate 10 between them and the inner wall of the hollow frame 1. Each limiting component 5 includes an outer sleeve 501, which is fixedly connected to the inner wall of the hollow frame 1. A positioning inner post 504 is slidably connected inside the outer sleeve 501. A limiting slip ring 503 is fixedly connected to one end of the positioning inner post 504 that passes through the outer sleeve 501. A return spring 502 is installed between the positioning inner post 504 and the inner wall of the outer sleeve 501. The end of the positioning inner post 504 away from the outer sleeve 501 is fixedly connected to the corresponding first action plate 9 and second action plate 10. The outer sleeve 501 and the positioning inner post 504 provide movement guidance for the first action plate 9 and the second action plate 10, making their movement more stable and avoiding skewing. At the same time, the return spring 502 provides elastic force so that the elastic sealing ring 701 can be tightly attached to the sealing ring groove 13.

[0036] Please see Figure 2 and Figure 6 The inner wall of the hollow frame 1 is provided with a suction assembly 6. The suction assembly 6 is used to drive the first actuating plate 9 and the second actuating plate 10 to move towards the inner wall of the hollow frame 1, thereby driving the sealing ring 7 to expand. The suction assembly 6 includes an electromagnet 601. The electromagnet 601 is fixedly connected to the hollow frame 1 at both ends near the first actuating plate 9 and the second actuating plate 10. Both ends of the first actuating plate 9 and the second actuating plate 10 are fixedly connected with iron parts 602 that match the electromagnet 601. When the electromagnet 601 is energized, it generates a magnetic force to attract the iron parts 602, causing the first actuating plate 9 and the second actuating plate 10 to move towards the inner wall of the hollow frame 1. The movement of the first actuating plate 9 and the second actuating plate 10 can drive the elastic sealing ring 701 to expand, so that the elastic sealing ring 701 can be dislodged from the sealing ring groove 13, so as to facilitate the subsequent rotation of the flipping frame 12.

[0037] Please see Figure 2 , Figure 3 and Figure 10Each rotating column 11 is equipped with a locking component 8 for locking the position of the flip frame 12. The locking component 8 includes a fixing ring 802, which is fixedly connected to the rotating column 11 between the second actuating plate 10 and the inner wall of the hollow frame 1. Locking slots 806 are provided on both sides of the fixing ring 802. Locking inserts 801 are fixedly connected to both sides of the second actuating plate 10 located on the rotating column 11. The locking inserts 801 are used to insert into the locking slots 806 to lock the fixing ring 802. A top ring 805 is fixedly connected to one end of the rotating column 11 near the inner wall of the hollow frame 1. A limiting arc groove 804 is provided on one side of the top ring 805. A top ring 805 is fixedly connected to the inner wall of the hollow frame 1 near the rotating column 11. A positioning pin 803 is provided, which is slidably connected in the limiting arc groove 804. When the second action plate 10 moves toward the inner wall of the hollow frame 1, the locking insert 801 moves together with the second action plate 10. As the second action plate 10 moves, the locking insert 801 will disengage from the locking slot 806. After disengaging, it will release the lock on the rotating column 11. After the lock on the rotating column 11 is released, the flip frame 12 can be rotated. At the same time, the limiting arc groove 804 and the positioning pin 803 can limit the rotation of the flip frame 12, so that the flip frame 12 can rotate within 0-180 degrees. When the second action plate 10 is reset, the locking insert 801 will also fall into the locking slot 806, locking the fixing ring 802 and the rotating column 11 to prevent the flip frame 12 from rotating.

[0038] The working principle of this invention is as follows: The hollow frame 1 is connected to the curtain wall keel via mounting holes 2 at its four corners, achieving a fixed installation of the overall structure. During daily use, the power-generating glass 303 converts solar energy into electrical energy for use inside the building, while the heating glass 302 raises the indoor temperature in winter, meeting both power generation and heating needs. Under normal conditions, under the elastic force of the return spring 502, the first and second action plates 9 and 10 drive the elastic sealing ring 701 of the sealing ring 7 to embed into the sealing ring groove 13 of the flip frame 12. Simultaneously, the side protrusion 702 adheres to the inner wall of the hollow frame 1, and the tension spring 703 tightens the edges of the elastic sealing ring 701, achieving a full circumferential seal. The locking insert 801 is inserted into the locking slot 806 of the fixing ring 802, cooperating with the positioning pin 803 and the limiting arc groove 804 to ensure the stability of the flip frame 12. When cleaning is required, the electromagnet 60 of the attraction component 6... When energized, the magnetic force attracts the iron part 602, causing the first actuating plate 9 and the second actuating plate 10 to move towards the inner wall of the hollow frame 1. This causes the elastic sealing ring 701 to disengage from the sealing ring groove 13, and at the same time, the locking insert 801 disengages from the locking slot 806, releasing the seal and lock on the flip frame 12. At this time, the flip frame 12 can be flipped within the range of 0-180 degrees by rotating the column 11, allowing the power-generating glass 303 on the exterior wall to be directly moved indoors, enabling cleaning from inside the room and avoiding the high risk of traditional curtain wall suspended cleaning. After cleaning, the flip frame 12 is rotated back to its original position. After rotation, the suction assembly 6 is de-energized, and the reset spring 502 pushes the first actuating plate 9 and the second actuating plate 10 to reset. The elastic sealing ring 701 is re-embedded into the sealing ring groove 13 to restore the seal, and at the same time, the locking insert 801 is re-inserted into the locking slot 806 to lock the flip frame 12 again, ensuring the stability of the flip frame 12.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
