Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall design technology, and in particular to a BIPV layered hollow glass curtain wall. Background Technology

[0002] In the field of Building Integrated Photovoltaics (BIPV), layered insulated glass curtain walls, as a key component combining power generation and building envelope performance, directly impact building energy efficiency and photovoltaic system reliability due to their thermal performance, ease of maintenance, and system stability. With the increasing prevalence of green buildings and renewable energy applications, modern building requirements for curtain walls have expanded from simple physical protection to a comprehensive system encompassing dynamic insulation, high-efficiency power generation, and intelligent operation and maintenance. Traditional BIPV curtain walls often employ static insulated layers and fixed structures, which, over long-term use, reveal issues such as reduced insulation performance and difficulties in maintaining photovoltaic modules. They are ill-suited to the energy-saving needs of buildings in different climates and the high frequency of maintenance required, necessitating technological innovation to improve the overall performance of curtain walls.

[0003] Existing BIPV (Building Integrated Photovoltaic) layered insulated glass curtain walls suffer from two major drawbacks: First, the static insulation mechanism lacks reliability. Traditional insulated layers use one-time gas filling or vacuum design, lacking continuous pressure regulation capabilities. As the sealing structure ages, gas leaks or vacuum layer damage can easily occur, leading to a significant decrease in insulation performance and an inability to maintain building insulation effects for an extended period. Second, the photovoltaic module maintenance process is cumbersome. Traditional integrated curtain walls use a closed structure, requiring the complete removal of the front or rear glass when the photovoltaic layer is damaged. This process is complex and requires specialized tools, which is not only time-consuming and labor-intensive but may also cause secondary damage to the curtain wall structure, posing safety hazards, especially in high-rise buildings. Furthermore, existing technologies lack integrated quick-unlocking and guiding structures, making it difficult to achieve independent replacement and rapid repositioning of photovoltaic modules, thus limiting the operation and maintenance efficiency and lifespan of BIPV curtain walls. These problems urgently need to be addressed through innovative designs such as dynamic gas path control and sliding-rotation linkage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a BIPV layered hollow glass curtain wall, which aims to solve the problems of heat insulation performance degradation and photovoltaic module maintenance difficulties in existing glass curtain walls.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A BIPV (Building Integrated Photovoltaic) layered hollow glass curtain wall includes a fixed frame with a cavity inside. A front glass is fixedly connected to the front end of the cavity. A photovoltaic solar cell layer is disposed on the rear side of the front glass. Sliding grooves are provided at the bottom ends of both sides of the fixed frame. Sliding components are disposed inside the sliding grooves. A rear glass is connected to the top rear side of the fixed frame via a pivot. A sealing ring is disposed between the rear glass and the front glass. A junction box is fixedly connected to the top side of the fixed frame.

[0007] Furthermore, the sliding assembly includes a slider, which is slidably connected inside the groove. Connecting blocks are fixedly connected to the opposite sides of the sliders at both ends, and the rear ends of the opposite sides of the connecting blocks at both ends are connected to a limiting plate via a rotating shaft.

[0008] Furthermore, abutment blocks are fixedly connected to the bottom ends of both the left and right sides of the fixed frame, and the front side of the limiting plate abuts against the rear side of the abutment blocks.

[0009] Furthermore, the bottom side of the limiting plate and the rear end of the top side of the abutment block are both provided with inclined surfaces.

[0010] Furthermore, an inflation tube is provided on the left side of the cavity, and an air pump is installed on the outer wall of the inflation tube. The right side of the air pump is fixedly connected to the left side of the fixed frame.

[0011] Furthermore, an air outlet pipe is provided on the right side of the cavity, and a vacuum pump is installed on the outer wall of the air outlet pipe. The left side of the vacuum pump is fixedly connected to the right side of the fixed frame.

[0012] Furthermore, a connecting wire is fixedly connected to the bottom side of the junction box, and the bottom end of the connecting wire passes through the fixed frame and is fixedly connected to the top side of the photovoltaic solar cell layer.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this invention, a vacuum pump and an air pump are started simultaneously to extract air from the photovoltaic solar cell layer and fill the cavity with insulating gas, forming an insulating layer through gas pressure regulation. This mechanism utilizes the physical properties of gas to block heat conduction, avoiding the potential damage risk of traditional vacuum layers, maintaining long-term insulating performance, adapting to the energy-saving needs of buildings in different climatic environments, and improving the overall thermal insulation effect of curtain walls.

[0015] 2. In this utility model, the limiting plate, through the cooperation of the inclined surfaces of the slider, connecting block, and abutment block, can unlock the rear glass by sliding upward and rotating. Maintenance access can be quickly opened without tools, enabling independent replacement of the photovoltaic solar cell layer. The maintenance process is simplified to three steps: "sliding—rotating—disassembling," significantly shortening maintenance time and avoiding damage to the curtain wall structure caused by overall disassembly, thus improving the convenience of operation and maintenance and the efficiency of component replacement.

Detailed Implementation

[0024] 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.

[0025] Reference Figure 1-6This utility model provides an embodiment of a BIPV (Building Integrated Photovoltaic) layered hollow glass curtain wall, including a fixed frame 1. The fixed frame 1 has a cavity 19 inside, and a front glass 2 is fixedly connected to the front end of the cavity 19. A photovoltaic solar cell layer 17 is disposed on the rear side of the front glass 2. Sliding grooves 13 are provided at the bottom ends of both sides of the fixed frame 1, and sliding blocks 14 are disposed inside the sliding grooves 13. The top end of the rear side of the fixed frame 1 is connected to a rear glass 9 via a pivot 8. A sealing ring is disposed between the rear glass 9 and the fixed frame 1. A junction box 3 is fixedly connected to the top side of the cavity 19. An inflation pipe 10 is provided on the left side of the cavity 19. An air pump 11 is installed on the outer wall of the inflation pipe 10. The right side of the air pump 11 is fixedly connected to the left side of the fixed frame 1. An air outlet pipe 4 is provided on the right side of the cavity 19. A vacuum pump 5 is installed on the outer wall of the air outlet pipe 4. The left side of the vacuum pump 5 is fixedly connected to the right side of the fixed frame 1. A connecting wire 18 is fixedly connected to the bottom side of the junction box 3. The bottom end of the connecting wire 18 passes through the fixed frame 1 and is fixedly connected to the top side of the photovoltaic solar cell layer 17.

[0026] Specifically, the installation process for this type of BIPV (Building Integrated Photovoltaic) layered insulated glass curtain wall revolves around dynamic heat insulation and convenient maintenance. First, after the overall positioning of the curtain wall is completed, the inflation pipe 10 is connected to the gas container, and the vacuum pump 5 and air pump 11 are started simultaneously. The former extracts air from the photovoltaic solar cell layer 17 through the exhaust pipe 4, while the latter injects heat-insulating gas into the cavity 19 through the inflation pipe 10, forming a dynamic heat insulation layer through dual-path circulation. This design improves the thermal barrier performance of the curtain wall through active air pressure regulation, avoiding the heat insulation failure problem caused by gas leakage in traditional static insulated layers. The heat insulation effect can be optimized in real time according to the ambient temperature. Simultaneously, the electrical energy generated by the photovoltaic solar cell layer 17 is fed into the junction box 3 through the connecting line 18, achieving efficient conversion and output of light energy into electrical energy.

[0027] Reference Figure 1-6 The slider 14 is slidably connected inside the slide groove 13. The two ends of the slider 14 are fixedly connected to the opposite side of each other. The rear ends of the two ends of the connecting blocks 15 are connected to the limit plate 6 through the rotating shaft 16. The bottom ends of the left and right sides of the fixed frame 1 are fixedly connected to the abutment block 7. The front side of the limit plate 6 abuts against the rear side of the abutment block 7. The bottom side of the limit plate 6 and the rear end of the top side of the abutment block 7 are both provided with inclined surfaces 12.

[0028] Specifically, when the photovoltaic solar cell layer 17 module requires maintenance, the limiting plate 6 is slid upwards, causing the slider 14 to move along the slide groove 13. The limiting plate 6 is then separated from the abutment block 7 via the connecting block 15. Subsequently, the limiting plate 6 is rotated and connected to the fixed frame 1 via the first rotating shaft 8, releasing the restriction on the rear glass 9 connected to the fixed frame 1 via the second rotating shaft 16. This opens the maintenance channel for replacing damaged modules. During installation, the inclined surfaces 12 on the bottom side of the limiting plate 6 and the top side of the abutment block 7 automatically guide the module, allowing for quick reset and locking without tools. This modular design, involving sliding and rotating linkage, breaks the traditional closed structure of curtain walls, enabling independent disassembly and replacement of the photovoltaic layer. This avoids material waste and structural damage caused by overall disassembly, significantly improving operation and maintenance efficiency and safety.

[0029] Working principle: After the curtain wall is installed in the required location, the inflation pipe 10 is connected to the container containing the required gas. Then, the vacuum pump 5 and the air pump 11 are started simultaneously. The vacuum pump 5 expels the air inside the photovoltaic solar cell layer 17, while the air pump 11 and the inflation pipe 10 draw the gas from the container into the cavity 19, thereby improving the heat insulation performance. After installation, the electricity generated by the photovoltaic solar cell layer 17 is output to the junction box 3 through the connecting line 18. This is done when the photovoltaic solar cell layer 17's components generate electricity. After damage, the limiting plate 6 first drives the slider 14 and connecting block 15 to slide upward, so that the front side of the limiting plate 6 no longer abuts against the rear side of the abutment block 7. Then, the limiting plate 6 is rotated so that the limiting plate 6 no longer limits the rear glass 9. Then the rear glass 9 is opened, and the photovoltaic solar cell layer 17 can be maintained and replaced. After the replacement is completed, the limiting plate 6 is slid downward. At the same time, when the limiting plate 6 is slid downward, the inclined surfaces opened on the top side of the abutment block 7 and the bottom side of the limiting plate 6 will contact first, so that the limiting plate 6 can slide to the bottom more easily.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
