Description

Technical Field

[0001] This invention relates to a curtain wall structure, and more particularly to a building photovoltaic glass curtain wall with adjustable light transmission and shading. Background Technology

[0002] Glass curtain walls are commonly used for the exterior facade decoration of building structures. With building structural design increasingly emphasizing energy conservation and environmental protection, photovoltaic (PV) glass curtain walls have emerged. The functional requirements of PV glass curtain walls include insulation, shading, lighting, power generation, and aesthetics. However, current PV glass curtain wall technologies cannot effectively balance lighting, shading, and power generation.

[0003] To achieve power generation, traditional photovoltaic (PV) glass curtain walls often sacrifice some sunlight and views, resulting in insufficient indoor lighting in most cases and inadequate shading during periods of strong sunlight, thus affecting residents' comfort. Furthermore, they cannot meet individualized lighting and shading needs based on climate conditions. Therefore, there is a need for a building-mounted PV glass curtain wall with adjustable lighting and shading capabilities, which can solve the problem of existing technologies failing to balance lighting, shading, and power generation. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable building photovoltaic glass curtain wall that can solve the problem that existing building photovoltaic glass curtain walls cannot balance lighting, shading and power generation.

[0005] This invention is implemented as follows:

[0006] An adjustable photovoltaic (PV) glass curtain wall for both light transmission and shading includes a sliding PV curtain wall module and a concealed PV curtain wall module. The sliding PV curtain wall module and the concealed PV curtain wall module are combined and spliced ​​to form a PV glass curtain wall structure. The sliding PV curtain wall module includes a sliding PV outer window frame, an outer glass layer, and an adjustable PV component. The adjustable PV component is embedded in the sliding PV outer window frame, and a pair of outer glass layers are embedded in the sliding PV outer window frame and located inside and outside the adjustable PV component. The concealed PV curtain wall module includes an outer glass layer, a concealed PV outer window frame, and a flexible PV component. The flexible PV component is rollable and embedded in the concealed PV outer window frame, and a pair of outer glass layers are embedded in the concealed PV outer window frame and located inside and outside the flexible PV component.

[0007] The adjustable photovoltaic component includes a sliding photovoltaic component and a fixed photovoltaic component. The sliding photovoltaic component is slidably embedded in a sliding photovoltaic outer window frame, and the fixed photovoltaic component is fixedly embedded in a sliding photovoltaic outer window frame. The sliding photovoltaic component and the fixed photovoltaic component are arranged in parallel. Several photovoltaic strips are arranged at intervals on both the sliding photovoltaic component and the fixed photovoltaic component, and the photovoltaic strips on the sliding photovoltaic component and the photovoltaic strips on the fixed photovoltaic component are arranged alternately. The parts of the sliding photovoltaic component and the fixed photovoltaic component that are not provided with several photovoltaic strips are light-transmitting structures.

[0008] The sliding photovoltaic component includes an elongated photovoltaic glass and a slotted slide rail. The top of the elongated photovoltaic glass is slidably mounted on the top of the inner wall of the sliding photovoltaic outer window frame via the slide rail, and the bottom of the elongated photovoltaic glass is slidably mounted on the bottom of the inner wall of the sliding photovoltaic outer window frame via the slotted slide rail through a sliding operation component. The sliding direction of the elongated photovoltaic glass is perpendicular to the length direction of the photovoltaic strip.

[0009] The sliding operation component includes a sliding main handle. One end of the sliding main handle passes through a slot into a slotted slide rail and is fixedly connected to the bottom of the extended photovoltaic glass. The other end of the sliding main handle passes through the sliding photovoltaic outer window frame and the outer glass and extends into the interior of the building structure.

[0010] The inner wall bottom of the sliding photovoltaic outer window frame is provided with a sealing strip, and the sliding main handle slides in a sealed manner with the inner wall bottom of the sliding photovoltaic outer window frame through the sealing strip.

[0011] The fixed photovoltaic component includes photovoltaic glass and mounting grooves, with the top and bottom of the photovoltaic glass respectively fixedly mounted in the sliding photovoltaic outer window frame.

[0012] The length of the sliding photovoltaic component is greater than that of the fixed photovoltaic component, and the side end of the sliding photovoltaic component can be slidably embedded into the reserved groove on the side end of the inner wall of the sliding photovoltaic outer window frame; the width of the photovoltaic strips on the sliding photovoltaic component and the fixed photovoltaic component is consistent with the spacing of the photovoltaic strips.

[0013] The flexible photovoltaic component includes a flexible photovoltaic body, a flexible photovoltaic clamp, and a slider. The bottom of the flexible photovoltaic body is rolled up inside the bottom of the hidden photovoltaic outer window frame via an elastic roller. Slide grooves are formed on both sides of the inner wall of the hidden photovoltaic outer window frame. Slide sliders are connected to the top two sides of the flexible photovoltaic body via the flexible photovoltaic clamp. The sliders are slidably embedded in the slide grooves, allowing the flexible photovoltaic body to unfold or roll up inside the hidden photovoltaic outer window frame.

[0014] The slider has an L-shaped structure. The horizontal section of the slider is connected to the top of the flexible photovoltaic body. The vertical section of the slider is equipped with a first strong magnetic block. The two ends of the magnetic lifting rod are equipped with second strong magnetic blocks. The second strong magnetic blocks attract the first strong magnetic blocks, so that the magnetic lifting rod is attached to the outer glass on the indoor side and attracts the top of the flexible photovoltaic component. The flexible photovoltaic component is then extended upward or rolled downward along the slide groove by the magnetic lifting rod and the slider.

[0015] The bottom of the concealed photovoltaic outer window frame has an installation cavity, a traceless baffle covers the installation cavity, and the two ends of the elastic roller are rotatably embedded in the installation cavity, so that the flexible photovoltaic body can be elastically wound on the elastic roller.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention utilizes the free combination and assembly of sliding photovoltaic curtain wall modules and concealed photovoltaic curtain wall modules to form a photovoltaic glass curtain wall structure. The photovoltaic glass curtain wall structure is rationally partitioned, and the sliding photovoltaic curtain wall modules and concealed photovoltaic curtain wall modules use different lighting and shading adjustment methods to maximize the use of solar energy for power generation while meeting the lighting and shading requirements. This achieves "reducing building energy consumption + improving the utilization rate of renewable energy", without wasting a single ray of sunlight, making the building more likely to reduce energy consumption and contributing to the realization of zero-energy buildings and zero-carbon buildings.

[0018] 2. This invention features a sliding photovoltaic curtain wall module. By sliding the extended photovoltaic glass relative to the photovoltaic glass, the photovoltaic strips and the light-transmitting parts can be overlapped, partially overlapped, or staggered. The light-transmitting area, shading area, and photovoltaic power generation area can be freely adjusted to meet the personalized lighting and shading needs under different climatic conditions and improve human comfort.

[0019] 3. This invention features a concealed photovoltaic curtain wall module. By winding the flexible photovoltaic body onto an elastic roller, the flexible photovoltaic body is concealed and the concealed photovoltaic outer window frame is fully transparent. At the same time, the magnetic force of the magnetic lifting rod is used to lift the flexible photovoltaic body into the concealed photovoltaic outer window frame, achieving shading and power generation. The light transmission area, shading area, and photovoltaic power generation area can be freely adjusted to meet the personalized lighting and shading needs under different climatic conditions and improve human comfort.

[0020] 4. This invention solves the problem that existing building photovoltaic glass curtain walls cannot achieve a good balance between lighting, shading and power generation efficiency, maximizing human comfort, improving photovoltaic power generation efficiency, reducing building energy consumption and carbon emissions, and saving operating costs. Residents can achieve different purposes such as simple lighting, simple shading, or a combination of lighting and shading according to their individual needs. It is suitable for various types of buildings such as large commercial office buildings, public buildings, residences, and industrial plants. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Please see the appendix Figure 1 To be continued Figure 3 An adjustable photovoltaic (PV) glass curtain wall for both light transmission and shading includes a sliding PV curtain wall module 101 and a concealed PV curtain wall module 201. The sliding PV curtain wall module 101 and the concealed PV curtain wall module 201 are combined and spliced ​​to form a PV glass curtain wall structure. The sliding PV curtain wall module 101 includes a sliding PV outer window frame 1, an outer glass layer 2, and an adjustable PV component. The adjustable PV component is embedded in the sliding PV outer window frame 1, and a pair of outer glass layers 2 are embedded in the sliding PV outer window frame 1 and located inside and outside the adjustable PV component. The concealed PV curtain wall module 201 includes an outer glass layer 2, a concealed PV outer window frame 5, and a flexible PV component 9. The flexible PV component 9 is rollable and embedded in the concealed PV outer window frame 5, and a pair of outer glass layers 2 are embedded in the concealed PV outer window frame 5 and located inside and outside the flexible PV component 9.

[0035] The sliding photovoltaic (PV) curtain wall module 101 can be used to adjust the PV power generation scale by sliding the PV components, thereby adjusting the PV area to meet personalized adjustments for power generation, shading, and lighting. The concealed PV curtain wall module 201 can be used to adjust the PV power generation scale by raising and lowering the flexible PV components 9, thereby adjusting the PV area to meet personalized adjustments for power generation, shading, and lighting. The sliding PV curtain wall module 101 and the concealed PV curtain wall module 201 can be combined and used in appropriate ways to meet different power generation, shading, and lighting requirements.

[0036] The outer glass 2 is used to protect the adjustable photovoltaic components and the flexible photovoltaic components 9. The outer glass 2 is made of traditional light-transmitting glass and is installed in the sliding photovoltaic outer window frame 1 and the hidden photovoltaic outer window frame 5 through a traditional sealing method, which will not be described in detail here.

[0037] Please see the appendix Figure 3 and attached Figure 7 The adjustable photovoltaic component includes a sliding photovoltaic component 7 and a fixed photovoltaic component 8. The sliding photovoltaic component 7 is slidably embedded in the sliding photovoltaic outer window frame 1, and the fixed photovoltaic component 8 is fixedly embedded in the sliding photovoltaic outer window frame 1. The sliding photovoltaic component 7 and the fixed photovoltaic component 8 are arranged in parallel. Several photovoltaic strips 701 are arranged at intervals on both the sliding photovoltaic component 7 and the fixed photovoltaic component 8. The photovoltaic strips 701 on the sliding photovoltaic component 7 and the photovoltaic strips 701 on the fixed photovoltaic component 8 are arranged alternately. The parts of the sliding photovoltaic component 7 and the fixed photovoltaic component 8 that are not provided with several photovoltaic strips are light-transmitting structures.

[0038] The sliding photovoltaic (PV) component 7 can slide relative to the fixed PV component 8. When the PV strips 701 of the sliding PV component 7 slide to overlap with the PV strips 701 of the fixed PV component 8, the PV area of ​​the adjustable PV component is minimized, resulting in the smallest power generation capacity. The portion of the sliding PV component 7 and the fixed PV component 8 where the PV strips 701 are mounted transmits light, maximizing the light transmission area. As the PV strips 701 of the sliding PV component 7 slide to become misaligned with the PV strips 701 of the fixed PV component 8, the power generation capacity gradually increases, and the light transmission area gradually decreases, until the PV strips 701 of the sliding PV component 7 and the fixed PV component 8 are completely misaligned, maximizing the power generation capacity. The adjustable PV component thus achieves the effect of shading.

[0039] Please see the appendix Figure 3 and attached Figure 5 The sliding photovoltaic component 7 includes an elongated photovoltaic glass 71 and a slotted slide rail 72. The top of the elongated photovoltaic glass 71 is slidably embedded in the top of the inner wall of the sliding photovoltaic outer window frame 1 via the slide rail (not shown in the figure), and the bottom of the elongated photovoltaic glass 71 is slidably embedded in the bottom of the inner wall of the sliding photovoltaic outer window frame 1 via the slotted slide rail 72 through the sliding operation component 3. The sliding direction of the elongated photovoltaic glass 71 is perpendicular to the length direction of the photovoltaic strip 701.

[0040] The extended photovoltaic glass 71 can adopt thin-film photovoltaic technology, with photovoltaic strips 701 vertically spaced on its surface, and the rest of the glass is transparent. The extended photovoltaic glass 71 is stably installed and slidable by using a slotted slide rail 72 and the slide rail.

[0041] Please see the appendix Figure 3 Appendix Figure 5 Appendix Figure 8 and attached Figure 9 The sliding operation component 3 includes a sliding main handle 31. One end of the sliding main handle 31 passes through a slot into the slotted slide rail 72 and is fixedly connected to the bottom of the extended photovoltaic glass 71. The other end of the sliding main handle 31 passes through the sliding photovoltaic outer window frame 1 and the outer glass 2 and extends into the interior of the building structure.

[0042] The sliding handle 31 extends into the room, making it easy for indoor users to control the sliding of the extended photovoltaic glass 71 and allowing for personalized adjustments.

[0043] Please see the appendix Figure 8 and attached Figure 9 The sliding photovoltaic outer window frame 1 has a sealing strip 32 at the bottom of its inner wall, and the sliding main handle 31 slides in a sealed manner with the bottom of the inner wall of the sliding photovoltaic outer window frame 1 through the sealing strip 32.

[0044] By setting the sealing strip 32, the internal space of the sliding photovoltaic outer window frame 1 is ensured to be sealed when the extended photovoltaic glass 71 slides.

[0045] Please see the appendix Figure 3 and attached Figure 5 The fixed photovoltaic component 8 includes photovoltaic glass 81 and mounting groove 82. The top and bottom of the photovoltaic glass 81 are respectively mounted in the mounting groove 82 and fixedly embedded in the sliding photovoltaic outer window frame 1.

[0046] The photovoltaic glass 81 can be made using thin-film photovoltaic technology, with photovoltaic strips 701 vertically spaced on its surface and the rest of the glass being transparent. The photovoltaic glass 81 is fixedly installed using the mounting groove 82.

[0047] Please see the appendix Figure 8 and attached Figure 9 The length of the sliding photovoltaic component 7 is greater than the length of the fixed photovoltaic component 8. The side end of the sliding photovoltaic component 7 can be slidably embedded into the reserved groove on the inner wall side end of the sliding photovoltaic outer window frame 1. The width of the photovoltaic strips 701 on the sliding photovoltaic component 7 and the fixed photovoltaic component 8 is consistent with the spacing of the photovoltaic strips 701.

[0048] The sliding photovoltaic component 7 covers the hollowed-out portion of the sliding photovoltaic outer window frame 1, and the sliding of the photovoltaic component 7 allows for adjustment of light intake and shading, while simultaneously controlling the photovoltaic area. During the sliding process, the photovoltaic component 7 is limited and guided by the reserved groove on the inner wall side of the sliding photovoltaic outer window frame 1. The width of the photovoltaic strips 701 is consistent with their spacing, so that when the photovoltaic strips 701 are completely staggered, an effective shading effect can be achieved.

[0049] Please see the appendix Figure 3 Appendix Figure 4 Appendix Figure 10 and attached Figure 11 The flexible photovoltaic component 9 includes a flexible photovoltaic body 91, a flexible photovoltaic clamp 92, and a slider 93. The bottom of the flexible photovoltaic body 91 is wound around the bottom of the hidden photovoltaic outer window frame 5 via an elastic roller 10. Slide grooves are formed on both sides of the inner wall of the hidden photovoltaic outer window frame 5. The top two sides of the flexible photovoltaic body 91 are respectively connected to sliders 93 via the flexible photovoltaic clamp 92. The sliders 93 are slidably embedded in the slide grooves, so that the flexible photovoltaic body 91 can be unfolded or wound around the hidden photovoltaic outer window frame 5.

[0050] The flexible photovoltaic main body 91 can be a combination of photovoltaic modules connected by flexible materials, both of which are opaque. The flexible photovoltaic main body 91 can be rolled up on the elastic scroll 10, allowing light to pass through the outer glass 2, thus achieving the overall light transmission effect of the concealed photovoltaic outer window frame 5. The flexible photovoltaic main body 91 can be released from the elastic scroll 10 and slide upward along the slide groove via the slider 93 to shield the concealed photovoltaic outer window frame 5. The light-receiving and shading areas can be adjusted according to the shading area of ​​the flexible photovoltaic main body 91, while also adjusting the photovoltaic power generation area of ​​the flexible photovoltaic main body 91.

[0051] Please see the appendix Figure 3 The slider 93 has an L-shaped structure. The horizontal section of the slider 93 is connected to the top of the flexible photovoltaic body 91. The vertical section of the slider 93 is provided with a first strong magnetic block. The two ends of the magnetic lifting rod 4 are provided with second strong magnetic blocks. The second strong magnetic blocks attract the first strong magnetic blocks, so that the magnetic lifting rod 4 is attached to the outer glass 2 located on the indoor side and attracts the top of the flexible photovoltaic component 9. The flexible photovoltaic component 9 is then spread upward or rolled downward along the slide groove through the slider 93 via the magnetic lifting rod 4.

[0052] The magnetic lifting rod 4 moves upward, simultaneously pulling the flexible photovoltaic component 9 upward. The flexible photovoltaic component 9 is released from the elastic scroll 10, and the spring inside the elastic scroll 10 is stretched and stores force. The magnetic attraction force between the second and first strong magnets balances the elastic force of the elastic scroll 10, thus adsorbing the flexible photovoltaic component 9 at the pulled-out height. The magnetic lifting rod 4 moves downward, and the spring inside the elastic scroll 10 resets, causing the elastic scroll 10 to rotate, thereby winding the flexible photovoltaic component 9 onto the elastic scroll 10.

[0053] Preferably, the shape and size of both ends of the magnetic lifting rod 4 are the same as the shape and size of the vertical section of the slider 93, thereby ensuring the attraction force of the magnetic lifting rod 4 on the slider 93, and thus keeping the top of the flexible photovoltaic component 9 moving vertically synchronously with the magnetic lifting rod 4.

[0054] Please see the appendix Figure 1 and attached Figure 2 The bottom of the hidden photovoltaic outer window frame 5 has an installation cavity, and the traceless baffle 6 covers the installation cavity. The two ends of the elastic roller 10 are rotatably embedded in the installation cavity through rotating bearings, so that the flexible photovoltaic body 91 can be elastically wound on the elastic roller 10.

[0055] The non-marking baffle 6 is installed in a detachable manner, facilitating maintenance of the elastic roller 10 and the flexible photovoltaic body 91. Both ends of the elastic roller 10 are mounted on the inner wall of the mounting cavity via rotating bearings and springs. When the elastic roller 10 rotates to release the flexible photovoltaic body 91, the springs are stretched, using the spring force to spread the flexible photovoltaic body 91, achieving the purpose of shading and power generation. Thus, when the flexible photovoltaic body 91 descends, the elasticity drives the elastic roller 10 to rotate in the opposite direction and wind around the flexible photovoltaic body 91, completing the storage of the flexible photovoltaic body 91.

[0056] Please see the appendix Figure 1 To be continued Figure 11 The method of use and working principle of this invention are as follows:

[0057] During the design and construction of the glass curtain wall, the number and combination of sliding photovoltaic curtain wall modules 101 and concealed photovoltaic curtain wall modules 201 can be adjusted in a personalized manner to form a photovoltaic glass curtain wall structure that meets the needs of lighting, shading and power generation.

[0058] In use, the extended photovoltaic glass 71 is slid along the slotted slide rail 72 from indoors using the sliding handle 31. This allows the photovoltaic strips 701 on the extended photovoltaic glass 71 to overlap, partially overlap, or be staggered with the photovoltaic strips 701 on the photovoltaic glass 81. This allows the light-transmitting area to be adjusted through the light-transmitting portion, while the shading area and photovoltaic power generation area are adjusted through the photovoltaic strips 701, balancing light collection, shading, and power generation to meet individual usage needs.

[0059] The flexible photovoltaic component 91 moves up or down synchronously via a magnetic lifting rod 4 along the outer glass 2 on the indoor side, and the top of the flexible photovoltaic component 91 moves up or down synchronously via a slider 93 using magnetic force. This enables the flexible photovoltaic component 91 to perform shading and power generation functions. The shading area of ​​the flexible photovoltaic component 91 within the hidden photovoltaic window frame 5 balances light collection, sun shading, and power generation, meeting personalized usage needs.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
