Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building energy saving, in particular to a photovoltaic louver profile assembly. BACKGROUND

[0002] With the urgent demand for clean energy and the continuous improvement of building energy saving standards, photovoltaic louver profiles, as an important part of building photovoltaic integration, play a key role in achieving building energy saving and space function composite. However, the photovoltaic louver profile assemblies on the current market still have many problems to be solved in structure design, function implementation and actual application.

[0003] Traditional photovoltaic louver profile assemblies are mostly assembled by welding or complex bolt connection. The welding process not only has high technical requirements for construction personnel, but also the high temperature generated in the welding process easily causes the profile to deform, affecting the overall appearance and structural stability; and the complex bolt connection needs to be repeatedly positioned and tightened, which is tedious and time-consuming, increasing the labor cost and construction period. In addition, once a component of the assembly is damaged, due to the limitation of the connection method, the surrounding components need to be disassembled in a large area for maintenance, which is difficult and costly, and it is difficult to meet the needs of modern building rapid installation and convenient maintenance.

[0004] The sealing structure design of the existing assembly generally has defects. Some products only rely on a single sealing strip for sealing, which cannot effectively block the intrusion of external factors such as wind, rain and dust. In the long-term use process, it causes problems such as short circuit of photovoltaic power generation laminated glass line and corrosion of metal components. At the same time, the poor sealing performance also makes it difficult to meet the requirements of building for sound insulation and noise reduction, and external noise can easily enter the room through the gap, affecting the comfort of the indoor environment.

[0005] Most of the traditional photovoltaic louver profile assemblies adopt straight-through air duct design. Although this structure can realize the basic ventilation function, the air inlet direction is single and the wind speed is uneven, which easily produces large wind noise, and cannot effectively guide and buffer the airflow. In strong wind weather, the straight-through air duct may also cause excessive wind pressure, causing damage to the assembly structure and posing a safety hazard. In addition, the single ventilation structure cannot meet the diversified needs of buildings for ventilation volume and effect under different climate conditions. SUMMARY

[0006] The present application provides a photovoltaic louver profile assembly, a stand column profile support, a louver cross beam profile and a secondary frame profile fixed photovoltaic power generation laminated glass, supplemented by sealing and damping structure, which has the functions of power generation, ventilation, sound insulation and efficient use of space.

[0032] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0033] like Figures 1 to 7 As shown, an embodiment of the present invention provides a photovoltaic louver profile assembly, including: a column profile 1 and photovoltaic laminated glass 2 disposed on the column profile 1, further including: a first louver crossbeam profile 3, both ends of which are fixed to both sides of the column profile 1; a first sub-frame profile 4, one side of which is slidably connected to the first louver crossbeam profile 3, and the other side of which is sleeved on the photovoltaic laminated glass 2; a second louver crossbeam profile 5, both ends of which are fixed to both sides of the column profile 1; a second sub-frame profile 6, one side of which is connected to the second louver crossbeam profile 5 by a snap-fit ​​structure, and the other side of which is sleeved on the photovoltaic laminated glass 2; a noise-reducing rubber pad 7, located between both sides of the column profile 1 and the ends of the first louver crossbeam profile 3 and the second louver crossbeam profile 5; a connecting bracket 8, fixed inside the first louver crossbeam profile 3 and the second louver crossbeam profile 5; and a self-tapping screw 9, the threaded end of which is screwed into the connecting bracket 8 and the column profile 1.

[0034] It also includes: a first structural adhesive 10, one side of which is fixed inside the first sub-frame profile 4 and the other side of which is fixed to the photovoltaic laminated glass 2; a first foam strip 11, one side of which is fixed inside the first sub-frame profile 4 and the other side of which is fixed to the photovoltaic laminated glass 2, and is located directly above the first structural adhesive 10; a first external sealant 12, one side of which is fixed inside the first sub-frame profile 4 and the other side of which is fixed to the photovoltaic laminated glass 2; a second structural adhesive 13, one side of which is fixed to the second sub-frame profile 6 and the other side of which is fixed to the photovoltaic laminated glass 2; a second foam strip 14, one side of which is fixed to the second louvered crossbeam profile 5 and the second sub-frame profile 6, and the other side of which is fixed to the photovoltaic laminated glass 2; and a second external sealant 15, one side of which is fixed inside the second louvered crossbeam profile 5 and the other side of which is fixed to the photovoltaic laminated glass 2.

[0035] Specifically, the column profile 1 is installed on the wall using angle brackets or fixing bolts; the first arc frame 16 is integrally formed from high-strength aluminum alloy, and its arc design has been optimized by fluid mechanics, with an arc of R150mm, which can effectively guide airflow to form a laminar flow state and reduce the wind resistance coefficient to 0.28; the first mating plate 17 and the first aluminum alloy angle bracket 20 have a sliding structure with a fitting accuracy of ±0.05mm, ensuring smooth sliding without loosening; the first buckle seat 18 and the first buckle plate 21 adopt a two-way barbed locking design, and the pull-out resistance after snapping is ≥800N, which can withstand the load of a level 12 typhoon; the first sliding seat 19 is equipped with a polytetrafluoroethylene wear-resistant guide rail with a friction coefficient ≤0.08, so that the sliding resistance of the first sub-frame profile 4 is ≤5N, and a single person can easily complete the installation and adjustment.

[0036] In another preferred embodiment of the present invention, a first arc-shaped frame 16 is fixed above the first louvered beam profile 3, a first connecting plate 17 is fixed below the first louvered beam profile 3, a first buckle seat 18 is fixed below the first louvered beam profile 3, and a first slide block 19 is fixed on the side of the first louvered beam profile 3 facing the first sub-frame profile 4; a first aluminum alloy corner bracket 20 is slidably disposed below the first connecting plate 17; a first buckle plate 21 is snapped below the first buckle seat 18; a first sliding plate 22 is slidably disposed inside the first slide block 19, and the first sliding plate 22 is fixed on the first sub-frame profile 4; a first fixing screw 23 is threaded onto the first aluminum alloy corner bracket 20.

[0037] In another preferred embodiment of the present invention, a second arc-shaped frame 24 is fixed below the second louvered beam profile 5, a second connecting plate 25 is fixed below the second louvered beam profile 5, a second snap-fit ​​seat 26 is fixed below the second louvered beam profile 5, a third snap-fit ​​seat 27 is fixed above the second louvered beam profile 5, and a second slide block 28 is fixed on the side of the second louvered beam profile 5 facing the second sub-frame profile 6; a second aluminum alloy corner bracket 29 is slidably disposed below the second connecting plate 25; a second snap-fit ​​plate 30 is snapped below the second snap-fit ​​seat 26; a third snap-fit ​​plate 31 is snapped above the third snap-fit ​​seat 27; a second sliding plate 32 is slidably disposed inside the second slide block 28; a second fixing screw 33 is threaded onto the second aluminum alloy corner bracket 29; two self-tapping screws 9 are provided on the same noise-reducing rubber pad 7, and both self-tapping screws 9 are located in the middle of the column profile 1.

[0038] Specifically, the second mating plate 25 and the second aluminum alloy corner bracket 29 are connected by an L-shaped groove sliding connection, with the groove width tolerance controlled within ±0.03mm to ensure connection rigidity. The second snap-fit ​​seat 26 and the second snap-fit ​​plate 30, as well as the third snap-fit ​​seat 27 and the third snap-fit ​​plate 31, adopt an elastic snap-fit ​​mechanism, which provides obvious tactile feedback when snapped in and emits a "click" sound after installation, facilitating quick confirmation by construction personnel. This allows for blind insertion installation and improves construction efficiency. The self-tapping screw 9 is made of SUS304 stainless steel to ensure a connection strength ≥1200N.

[0039] Working principle: When the photovoltaic louver profile module is in operation, the various components work together to achieve its functions such as structural stability, sealing, ventilation and photovoltaic power generation. It is fixed to the building wall and assembled into a photovoltaic curtain wall.

[0040] In terms of structural connection, the column profile 1 serves as the main supporting component, providing basic support for the entire assembly; the first louvered crossbeam profile 3 and the second louvered crossbeam profile 5 are fixed to both sides of the column profile 1 by connecting brackets 8 and self-tapping screws 9. The connecting brackets 8 enhance the connection strength between the crossbeam and the column, and the self-tapping screws 9 pass through the threads of the connecting brackets 8 and are screwed into the column profile 1 to ensure a firm connection; in addition, each noise-absorbing rubber pad 7 is equipped with two self-tapping screws 9 located in the middle of the column profile 1, which not only ensures the reliability of the connection, but also effectively buffers vibration and reduces noise transmission.

[0041] The first sub-frame profile 4 and the first louvered crossbeam profile 3 are connected by a sliding connection. The first sliding seat 19 on the first louvered crossbeam profile 3 cooperates with the first sliding plate 22 on the first sub-frame profile 4, so that the first sub-frame profile 4 can slide along the first louvered crossbeam profile 3, which is convenient for installation and adjustment. The second sub-frame profile 6 and the second louvered crossbeam profile 5 are connected by a snap-fit ​​structure. The third snap-fit ​​seat 27 on the second louvered crossbeam profile 5 cooperates with the third snap-fit ​​plate 31 and other snap-fit ​​components to improve the appearance and achieve quick installation. This hanging installation method is convenient, quick and reliable.

[0042] In terms of sealing and fixing, the first structural adhesive 10, the first foam strip 11, and the first external sealant 12 work together. The first structural adhesive 10 firmly bonds the first sub-frame profile 4 to the photovoltaic laminated glass 2, the first foam strip 11 fills the gap and provides cushioning, and the first external sealant 12 further seals to prevent external moisture, dust, etc. from entering. Similarly, the second structural adhesive 13, the second foam strip 14, and the second external sealant 15 play the same fixing and sealing role for the second sub-frame profile 6 and the photovoltaic laminated glass 2, ensuring the sealing and stability of the module.

[0043] In terms of ventilation, the first arc frame 16 and the second arc frame 24 form an arc-shaped ventilation channel. When the photovoltaic laminated glass 2 generates heat during operation, the air flows through the arc-shaped channel. On the one hand, the arc structure makes the air intake more gentle and uniform, avoiding the discomfort caused by direct blowing. On the other hand, the airflow enables ventilation of the curtain wall, which can promptly remove the heat generated by the glass and ensure the efficient and stable operation of the components.

[0044] In terms of power generation, the photovoltaic laminated glass 2 serves as the core component, utilizing the photovoltaic effect to convert solar energy into electrical energy, providing power support for the system.

[0045] In terms of structural design and ease of installation, the sliding connection between the first louvered crossbeam profile 3 and the first sub-frame profile 4, and the snap-fit ​​connection between the second louvered crossbeam profile 5 and the second sub-frame profile 6, greatly simplify the installation process. Construction personnel can quickly assemble the components without complicated tools or professional skills, significantly shortening the installation period and reducing labor costs. At the same time, this modular design facilitates later maintenance and component replacement. When a part is damaged, it can be disassembled and repaired or replaced individually without large-scale disassembly of the entire component, effectively improving maintenance efficiency.

[0046] In terms of energy conservation and environmental protection, photovoltaic laminated glass 2 converts solar energy into electrical energy, reducing dependence on the traditional power grid, lowering building energy consumption, and achieving green energy self-sufficiency; the good sealing performance of the components, combined with the arc-shaped ventilation channel, can block some solar radiation heat from entering the room in summer, reducing the frequency of air conditioning use; in winter, it can prevent indoor heat loss, reduce heating energy consumption, and achieve significant energy-saving effects; in addition, the setting of noise-absorbing rubber pads 7 can not only buffer vibration and reduce noise, but also reduce the interference of external noise on the indoor environment, creating a quiet and comfortable living and working space for users.

[0047] In terms of durability and safety, the combination of connecting corner bracket 8 and self-tapping screw 9 enhances the overall structural strength of the module, enabling it to withstand greater external forces and resist the effects of severe weather, such as strong winds and heavy rain, thus extending its service life. The multi-layer sealing design of the first structural adhesive 10, the first foam strip 11, the first external sealant 12, the second structural adhesive 13, the second foam strip 14, and the second external sealant 15 effectively prevents moisture and dust from entering, avoiding internal components from getting damp, rusting, and aging, further improving the module's durability. The laminated structure of the photovoltaic laminated glass 2 has good impact resistance, so even if the glass breaks accidentally, it will not scatter into sharp fragments, ensuring personnel safety.

[0048] From an aesthetic and space utilization perspective, the curved design of the first curved frame 16 and the second curved frame 24 not only achieves gentle ventilation but also gives the components a unique appearance, making them more modern and artistic, and adaptable to various architectural styles. The reasonable layout of the first louvered beam profile 3 and the second louvered beam profile 5 with the column profile 1 makes full use of the building facade space, achieving functions such as photovoltaic power generation, ventilation, and sound insulation without occupying too much indoor space, thus improving space utilization.

[0049] The first arc-shaped frame 16 and the second arc-shaped frame 24 form an arc-shaped ventilation channel for curtain wall ventilation, providing gentle airflow. Verified by professional fluid dynamics software simulation, at a wind speed of 5 m / s, the airflow velocity distribution uniformity within the channel reaches 92%, reducing noise by 4-6 dB compared to traditional straight ventilation ducts. The first louvered beam profile 3 and the second louvered beam profile 5 are connected to the first sub-frame profile 4 and the second sub-frame profile 6 via a hook-and-loop installation method, ensuring convenient and reliable installation. Actual testing shows that single-person installation efficiency is 60% higher than traditional bolt connections, and the connection performance shows no significant decrease after 50 repeated disassembly and reassembly cycles. The first structural adhesive 10, the first foam strip 11, and the first external sealant 12, along with the second structural adhesive 13, the second foam strip 14, and the second external sealant 15, provide fixed installation and effective sealing. Tested according to GB / T 15227-2017 standards, the component's airtightness reaches level 8, its watertightness reaches level 6 (500 Pa), and its wind pressure resistance reaches level 5. Level (±3.0 kPa).

[0050] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
