Description

Technical Field

[0001] This application relates to the field of photovoltaic curtain wall technology, and in particular to a photovoltaic curtain wall dry-hanging system. Background Technology

[0002] Photovoltaic power generation, also known as solar power generation, is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. The key component of this technology is the solar cell. Solar cells are connected in series and then encapsulated for protection to form a large-area solar cell module. Combined with components such as a power controller, this forms a photovoltaic power generation device.

[0003] Currently, integrating photovoltaic products into buildings as solar buildings is becoming a trend in architectural development, such as photovoltaic curtain walls and photovoltaic skylights. Among them, photovoltaic curtain walls are mostly installed on the exterior walls of buildings through dry-hanging systems. The existing dry-hanging systems mainly consist of mounting frames composed of longitudinal and transverse keels. Each transverse keel is equipped with multiple photovoltaic modules through a hanging structure. However, since the existing transverse keels are pre-installed on the exterior walls of buildings, the height of the transverse keels cannot be adjusted during the installation of photovoltaic curtain walls. Furthermore, construction errors are inevitable during the pre-installation of the transverse keels, which leads to installation errors in the photovoltaic modules mounted on each transverse keel. This results in differences in the longitudinal spacing between the photovoltaic modules and poor installation effect.

[0004] Furthermore, in existing technologies, the upper and lower brackets of a single frame are typically hung from the top down on the support brackets. This makes the single frame prone to jumping off and falling when subjected to upward forces (such as earthquakes), posing a safety hazard. To eliminate this safety hazard, existing technologies usually prevent the brackets from jumping off by setting anti-jumping brackets or using screws to fix the brackets. However, this makes the bracket system more complex and the installation more cumbersome. Summary of the Invention

[0005] Based on this, a photovoltaic curtain wall dry-hanging system is provided to solve the problems of large installation errors, complex structure, and cumbersome installation steps in the existing dry-hanging system for photovoltaic curtain walls.

[0024] The second adjusting and locking assembly includes a second adjusting structure for adjusting the relative position of the adapter and the longitudinal keel, and a second locking member for locking the longitudinal keel and the adapter.

[0025] In one embodiment, the adapter includes two L-shaped plates formed by a first side plate and a second side plate, and the two L-shaped plates are symmetrically arranged on both sides of the longitudinal keel.

[0032] The beneficial effects of this plan are:

[0033] This photovoltaic curtain wall dry-hanging system uses individual frames to hang photovoltaic modules. The upper and lower hangers on these individual frames then connect with the lower and upper hooks on the longitudinal keels, thus securing the photovoltaic modules to the longitudinal keels. When several photovoltaic modules are arranged in an array on the longitudinal keels, a photovoltaic curtain wall is formed. This embodiment uses a dry-hanging connection, which is simple and easy to operate, improving the installation efficiency of photovoltaic modules, thereby saving labor and construction costs and bringing better economic benefits.

[0034] In this design, the absence of horizontal keels saves costs while improving keel installation efficiency. Simultaneously, this design directly installs the mounting components on the longitudinal keels. The mounting components can be adjusted arbitrarily along the length of the longitudinal keels within their limiting grooves. This allows for height adjustment based on construction needs, enabling height adjustment during installation according to the gap between the upper and lower photovoltaic modules. This reduces installation errors, ensures a tight connection between the upper and lower photovoltaic modules, and improves the uniformity and aesthetics of the gaps between photovoltaic modules on the exterior facade of the photovoltaic curtain wall. Furthermore, the lower bracket, mounted on the upper hook, achieves the lower limit of the individual frame, while the upper bracket, inserted into the lower hook, achieves the upper limit. This prevents the individual frame from jumping upwards or sinking downwards, ensuring stable engagement between the upper and lower load-bearing components and guaranteeing excellent positioning reliability in the longitudinal direction, resisting radial and longitudinal loads. Compared to existing technologies, this design is simpler, easier to install, and offers better mounting reliability. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation.

[0045] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "lateral," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] The photovoltaic curtain wall dry-hanging system provided in at least one embodiment of the present invention includes a hanging unit and a supporting unit. The hanging unit includes a plurality of individual frames arranged in an array. The upper and lower edges of the individual frames are respectively provided with upper hangers and lower hangers. The upper hanger includes an upper hanging groove with an upward opening, and the lower hanger includes a lower hanging groove with a downward opening. The supporting unit includes a plurality of longitudinal keels and a plurality of supporting components arranged sequentially along the length direction of each longitudinal keel. Each pair of adjacent individual frames corresponds to a longitudinal keel, and each pair of adjacent individual frames corresponds to a supporting component. The supporting component includes an upper hook and a lower hook. The individual frames located above the supporting component are hung on the upper hooks through the lower hanging grooves, and the individual frames located below the supporting component are inserted and engaged with the lower hooks through the upper hanging grooves.

[0047] The photovoltaic curtain wall dry-hanging system provided in the above embodiments of the present invention uses a single frame to hang photovoltaic modules, and then uses upper and lower hangers on the single frame to connect with lower and upper hooks on the longitudinal keel, thereby hanging the photovoltaic modules on the longitudinal keel. When several photovoltaic modules are arranged in an array and hung on the longitudinal keel, a photovoltaic curtain wall is formed. This embodiment adopts a dry-hanging connection, which is simple and easy to operate, improves the installation efficiency of photovoltaic modules, and thus saves labor costs and construction time costs, bringing good economic benefits.

[0048] In the above embodiments, the design without horizontal keels saves costs while improving the installation efficiency of the keel. Simultaneously, this embodiment directly installs the mounting components on the longitudinal keel. The mounting components can be adjusted arbitrarily along the length of the longitudinal keel, allowing the height of the mounting components to be adjusted according to construction needs. Furthermore, during installation, the height of the mounting components can be adjusted based on the gap between the upper and lower photovoltaic modules, thereby achieving height adjustment of the photovoltaic modules, reducing installation errors, ensuring a tight connection between the upper and lower photovoltaic modules, and improving the uniformity and aesthetics of the gaps between photovoltaic modules on the exterior facade of the photovoltaic curtain wall.

[0049] In the above embodiment, the lower hanger is attached to the upper hook to achieve the lower limit of the single frame, while the upper hanger and the lower hook are inserted together to achieve the upper limit of the single frame. This prevents the single frame from jumping upwards or sinking downwards, ensuring it is stably secured between the upper and lower load-bearing components. This guarantees good positioning reliability of the single frame in the longitudinal direction and allows it to resist radial and longitudinal loads. Furthermore, in this embodiment, the upper and lower limits of the single frame are achieved solely through the cooperation of the hanger and hook. Compared to existing technologies, this embodiment reduces the need for anti-jump components and fixing structures, resulting in a simpler structure, easier installation, and better mounting reliability.

[0050] The embodiments and examples of the present invention will now be described in detail with reference to the accompanying drawings.

[0051] Figure 1 This is a schematic diagram of a photovoltaic curtain wall dry-hanging system provided in some embodiments of the present invention. For ease of description, in this embodiment, Figure 1 The left-right direction is denoted as X-direction, the front-back direction as Y-direction, and the length direction of the longitudinal keel 40 as Z-direction. All orientations in this embodiment are relative positions and do not limit the scope of this application.

[0052] like Figure 1 As shown, at least one embodiment of the present invention provides a photovoltaic curtain wall dry-hanging system including a hanging unit and a supporting unit.

[0053] The mounting unit is fixedly installed on the main building structure 100 to provide mounting support for the hanging unit. In this embodiment, the main building structure 100 is the building's exterior wall.

[0054] Specifically, in this embodiment, the mounting unit includes multiple longitudinal keels 40, each of which is fixedly installed on the wall surface of the building exterior wall in a vertical direction, and the multiple longitudinal keels 40 are arranged at intervals to form a support frame for installing the photovoltaic module 10 on the wall surface of the building exterior wall.

[0055] To ensure the supporting strength of the longitudinal keel 40, in this embodiment, the longitudinal keel 40 is made of metal material. For example, the longitudinal keel 40 can be a rectangular aluminum alloy keel or a rectangular steel keel.

[0056] It should be noted that, in this embodiment, the number and spacing of the longitudinal keels 40 are mainly determined based on the dimensions of the building's exterior wall and the width of the photovoltaic modules 10. Generally speaking, the number and spacing of the longitudinal keels 40 are sufficient to ensure that each row of photovoltaic modules 10 has longitudinal keels 40 on both sides to provide installation support, provided that the photovoltaic modules 10 can cover the entire wall surface. The following description uses only a single longitudinal keel 40 as an example to illustrate its structure and fit.

[0057] See Figure 1 and 2 In this embodiment, multiple locking mechanisms for fixing the longitudinal keel 40 to the building exterior wall are provided at intervals along the length direction of the longitudinal keel 40. Each locking mechanism includes a connector, a first adjusting locking component, and a second adjusting locking component. The first adjusting locking component includes a first adjusting structure for adjusting the relative position of the connector and the building exterior wall, and a first locking structure for locking the connector and the building exterior wall. The second adjusting locking component includes a second adjusting structure for adjusting the relative position of the longitudinal keel 40 and the connector, and a second locking structure for locking the connector and the longitudinal keel 40.

[0058] The adapter is an intermediate connector. It is fixedly connected to the building exterior wall through the first adjusting and locking component, and fixedly connected to the longitudinal keel 40 through the second adjusting and locking component. In this way, the longitudinal keel 40 and the building exterior wall can be fixedly connected.

[0059] Specifically, see Figure 1 In this embodiment, the adapter includes two L-shaped plates 70 composed of a first side plate 701 and a second side plate 702, and the two L-shaped plates 70 are symmetrically arranged on both sides of the longitudinal keel 40. The first side plates 701 of the two L-shaped plates 70 are fixedly connected to the building exterior wall through a first adjusting and locking assembly, and the second side plates 702 of the two L-shaped plates 70 are fixedly connected to the two side walls of the longitudinal keel 40 through a second adjusting and locking assembly.

[0060] See Figure 1 In this embodiment, two L-shaped plates 70 are symmetrically arranged on both sides of the longitudinal keel 40, and the side of the two L-shaped plates 70 closest to the building exterior wall is attached to the wall surface, which is the first side plate 701; the side of the two L-shaped plates 70 closest to the longitudinal keel 40 is attached to the left and right side walls of the longitudinal keel 40 respectively, which is the second side plate 702. In this way, the longitudinal keel 40 can be clamped and fixed by the two L-shaped plates 70, thereby realizing the fixation of the longitudinal keel 40 and the adapter.

[0061] To ensure the connection strength of the adapter, in this embodiment, the L-shaped plate 70 is made of metal, such as aluminum alloy or steel.

[0062] See Figure 1 In this embodiment, the first adjustment structure includes a fixing member 77 and two first movable members. The fixing member 77 is fixedly installed on the exterior wall of the building, and the two first movable members are movably installed on the fixing member 77 along the X direction. The two first side plates 701 are movably installed on the two first movable members along the Z direction. The first locking structure includes two first locking members that lock the two first side plates 701 and the first movable members to the fixing member 77 respectively.

[0063] Based on the above structural design, during installation, the position of the first side plate 701 in the X-direction can be adjusted by the movement of the first movable component on the fixed component 77, thereby adjusting the position of the longitudinal keel 40 in the X-direction. This can absorb the construction deviation in the X-direction inherent in the building's exterior wall. Similarly, by moving the first side plate 701 along the first movable component in the Z-direction, the position of the first side plate 701 in the Z-direction can be adjusted, thereby adjusting the position of the longitudinal keel 40 in the Z-direction. This can absorb the construction deviation in the Z-direction inherent in the building's exterior wall. After completing the X-direction and Z-direction adjustments, the two first side plates 701 can be fixed to the fixed component 77 by the first locking component, thus achieving the fixed installation of the longitudinal keel 40 to the building's exterior wall.

[0064] The first adjusting locking component mentioned above can absorb construction errors of the building's exterior wall in the X and Z directions, ensuring the installation accuracy of the longitudinal keel 40, and thus guaranteeing the installation accuracy of the photovoltaic curtain wall.

[0065] Specifically, see Figure 1 and Figure 2 In this embodiment, the fixing member 77 is provided with an X-direction adjustment groove 79 extending in the X direction, and the X-direction adjustment groove 79 is a T-shaped groove. The first movable member is a T-bolt 74, and the head of the T-bolt 74 extends into the X-direction adjustment groove 79. The first side plate 701 is provided with a Z-direction adjustment hole 80 extending in the Z direction. The shank of the T-bolt 74 passes through the Z-direction adjustment hole 80. The first locking member is a first nut 75 that is screwed onto the T-bolt 74.

[0066] In this embodiment, the fastener 77 is a steel component, such as a rectangular steel component, see [reference needed]. Figure 2 It is fixedly installed into the exterior wall of the building by pre-embedding. For example, when constructing the main structure 100 of the building, the fastener 77 can be pre-embedded into the exterior wall of the building. And when the fastener 77 is pre-embedded into the exterior wall of the building, the opening of the X-direction adjustment groove 79 faces to the right and is exposed on the wall surface to facilitate the adjustment operation of the first movable part.

[0067] Of course, in other embodiments, the fastener 77 can also be fixed to the exterior wall of the building by means of post-installation. For example, if the main structure 100 of the building has been completed, the fastener 77 can be fixed to the exterior wall of the building by means of screw connection, welding or other methods.

[0068] The head of the T-bolt 74 is adapted to the shape of the T-slot, allowing it to move in the X direction along the T-slot, and the T-slot can be used to limit the Y direction between the T-bolt 74 and the fastener 77.

[0069] The Z-direction adjustment hole 80 is an elongated hole provided on the first side plate 701 and extending in the Z direction. The width of the Z-direction adjustment hole 80 is slightly larger than the diameter of the shank of the T-bolt 74, so that the shank of the T-bolt 74 can just pass through the Z-direction adjustment hole 80, and the X-direction limit between the T-bolt 74 and the first side plate 701 can be achieved through the Z-direction adjustment hole 80.

[0070] Based on the above structural design, when installing the adapter, the first side plate 701 is fitted onto the shank of the T-bolt 74 through the Z-axis adjustment hole 80. Then, the Z-axis and X-axis positions are adjusted. After adjustment, the first nut 75 is tightened onto the T-bolt 74, locking the first side plate 701 to the building's exterior wall, thus fixing the adapter to the exterior wall. This design method features a simple overall structure, good stability, ease of installation, and convenient construction.

[0071] See Figure 1 In some embodiments, the first adjusting locking assembly further includes a first limiting washer 76 disposed on the two first side plates 701. The first limiting washer 76 is provided with a first limiting hole through which the shank of the T-bolt 74 passes. The two first limiting washer 76 are respectively sleeved on the shank of the two T-bolts 74 through the first limiting hole, and the two first limiting washer 76 are used to fix the first side plate 701 after the Z-direction adjustment of the longitudinal keel 40 is completed.

[0072] The first limiting hole is adapted to the shank of the T-bolt 74, that is, the diameter of the first limiting hole is equal to or slightly larger than the diameter of the shank of the T-bolt 74, so that the first limiting washer 76 can be fitted onto the T-bolt 74, and the first limiting washer 76 and the T-bolt 74 can be limited in the radial direction. For example, if the diameter of the shank of the T-bolt is 10mm, then the first limiting hole can be a round hole with a diameter of 10mm or 10.5mm.

[0073] The first limiting gasket 76 can be fixed to the first side plate 701 by means of bolt connection, riveting connection or welding. For example, the first limiting gasket 76 is fixed to the first side plate 701 by welding. When installing the adapter, the first limiting gasket 76 is freely sleeved on the first movable part. At this time, the adapter can move in the Z direction along the first movable part through the Z-direction adjustment hole 80. After the Z-direction position of the longitudinal keel 40 is adjusted, the first nut 75 is tightened to lock the first limiting gasket 76 on the first side plate 701. Then, the first limiting gasket 76 is welded and fixed to the first side plate 701. At this time, the first limiting hole on the first limiting gasket 76 can radially limit the adapter to prevent the adapter from shifting and ensure the stability of the dry-hanging system.

[0074] In this embodiment, the first limiting gasket 76 is made of metal, such as aluminum alloy or steel, to ensure the strength and connection stability of the first limiting gasket 76.

[0075] See Figure 1 In this embodiment, the second adjustment structure includes a Y-direction adjustment hole 78 disposed opposite to the two second side plates 702 and extending in the Y direction, and a second movable member that passes through the longitudinal keel 40 and the Y-direction adjustment hole 78 on both sides; the second locking structure is disposed at the end of the second movable member and is used to lock the two second side plates 702 onto the two side walls of the longitudinal keel 40 respectively.

[0076] Based on the above structural design, during installation, the second movable component can be moved along the Y-axis adjustment hole 78 to adjust its position in the Y-axis, thus adjusting the position of the longitudinal keel 40 in the Y-axis. This absorbs any construction deviations in the Y-axis of the building's exterior wall, ensuring the installation accuracy of the photovoltaic curtain wall. After the Y-axis adjustment is completed, the two second side plates 702 can be locked to the two side walls of the longitudinal keel 40 using the second locking structure, thereby achieving a fixed installation of the longitudinal keel 40 and the adapter, and thus a fixed installation of the longitudinal keel 40 and the building's exterior wall.

[0077] Specifically, see Figure 1 In this embodiment, the second locking structure includes a second bolt 71 and a second nut 72. A through hole is provided on the longitudinal keel 40, which is opposite to the two Y-direction adjustment holes 78. The shank of the second bolt 71 extends through the through hole and the Y-direction adjustment holes 78 on both sides to the outside of the longitudinal keel 40. The second nut 72 is screwed onto the second bolt 71.

[0078] The through hole on the longitudinal keel 40 is a round hole with a diameter slightly larger than the diameter of the shank of the second bolt 71, so that the second bolt 71 can just pass through the through hole and can limit the second bolt 71 in the radial direction.

[0079] Based on the above structure, during assembly, the shank of the second bolt 71 passes sequentially through the Y-direction adjustment hole 78 of the left second side plate 702, the through hole on the longitudinal keel 40, and the Y-direction adjustment hole 78 of the right second side plate 702 before extending outward. Then, the second bolt 71 is tightened, thereby locking and fixing the two second side plates 702 to the side walls of the longitudinal keel 40 respectively, thus completing the fixed installation of the longitudinal keel 40 and the adapter. This design method features a simple overall structure, good stability, ease of installation, and convenient construction.

[0080] See Figure 1 In some embodiments, a first anti-corrosion pad 60 is provided between the second side plate 702 and the side wall of the longitudinal keel 40 to prevent electrochemical corrosion between the second side plate 702 and the longitudinal keel 40.

[0081] See Figure 1 and Figure 2 In some embodiments, the second adjusting locking assembly further includes a second limiting washer 73 disposed on the two second side plates 702. The second limiting washer 73 is provided with a second limiting hole adapted to the second bolt 71. The two second limiting washer 73 are respectively sleeved on the second bolt 71 through the second limiting hole, and the two second limiting washer 73 are used to fix the second side plate 702 after the Y-direction adjustment of the longitudinal keel 40 is completed.

[0082] The second limiting hole and the second movable part are adapted to each other, meaning that the diameter of the second limiting hole is equal to or slightly larger than the diameter of the shank of the second bolt 71, so that the second limiting washer 73 can be fitted onto the movable part and achieve limiting in the radial direction. For example, if the diameter of the shank of the second bolt 71 is 10mm, then the second limiting hole can be a round hole with a diameter of 10mm or 10.5mm.

[0083] The second limiting washer 73 can be fixed to the second side plate 702 by means of bolt connection, riveting connection, or welding. For example, the second limiting washer 73 can be fixed to the second side plate 702 by welding. When installing the adapter, the second limiting washer 73 is freely sleeved on the second bolt 71. At this time, the longitudinal keel 40 can drive the second bolt 71 to move in the Y direction along the Y-direction adjustment hole 78 to adjust the Y-direction position of the longitudinal keel 40. After the adjustment is completed, the second nut 72 locks the second limiting washer 73 on both sides onto the second side plate 702. Finally, the second limiting washer 73 is welded and fixed onto the second side plate 702. At this time, the second limiting hole on the second limiting washer 73 can radially limit the second moving part to prevent the longitudinal keel 40 from radially shifting and ensure the stability of the dry-hanging system.

[0084] See Figure 2In this embodiment, each second side plate 702 is provided with two Y-direction adjustment holes 78. Correspondingly, the longitudinal keel 40 is provided with two through holes respectively opposite to the two Y-direction adjustment holes 78. The second limiting washer 73 is provided with two second limiting holes respectively opposite to the two through holes. A second bolt 71 is provided between each set of Y-direction adjustment holes 78, through holes, and second limiting holes, and is locked by a second nut 72. In this way, by providing two sets of Y-direction adjustment holes 78, the circumferential rotation between the second bolt 71 and the second side plate 702 can be limited, ensuring the connection stability between the adapter and the longitudinal keel 40.

[0085] Through the above structural design, the longitudinal keel 40 can be adjusted in six degrees of freedom in the front-back, vertical, and left-right directions, thereby absorbing the construction deviation of the building exterior wall and ensuring the installation accuracy of the photovoltaic curtain wall.

[0086] In this embodiment, each longitudinal keel 40 is provided with a plurality of mounting components 30 along its length, and the mounting components 30 are used to mount the photovoltaic modules 10. In this embodiment, the mounting components 30 can be made of aluminum alloy, steel or stainless steel.

[0087] See Figure 3 In this embodiment, the hanging component 30 includes a base 35 and a connecting arm 33. The base 35 is fixedly connected to the longitudinal keel 40. One end of the connecting arm 33 is connected to the base 35, and the other end of the connecting arm 33 is connected to the upper hook 31 and the lower hook 32.

[0088] See Figure 3 The base 35 is a plate-shaped structure with screw mounting holes 36. During installation, stainless steel screws 90 can be passed through the screw mounting holes 36 to fix the base 35 to the outer wall of the longitudinal keel 40, thereby realizing the connection between the hanging component 30 and the longitudinal keel 40.

[0089] See Figure 4 and Figure 5 In some embodiments, the longitudinal keel 40 is provided with a limiting structure that cooperates with the base 35. The limiting structure includes a limiting groove 41 provided along the length direction of the longitudinal keel 40, and the base 35 is embedded in the limiting groove 41.

[0090] In the above structural design, the setting of the limiting groove 41 can realize the limiting of the base 35 in the X and Y directions, ensuring that the base 35 and the longitudinal keel 40 are quickly and accurately positioned, improving the convenience of installation, while avoiding the offset of the base 35 in the X and Y directions, and improving the assembly reliability of the base 35 and the longitudinal keel 40.

[0091] See Figure 4In one example, the limiting groove 41 is formed directly on the side of the longitudinal keel 40 near the monolithic frame 20.

[0092] For example, see Figure 4 In this example, both ends of the outer wall of the longitudinal keel 40 are integrally formed with outwardly extending plates, and the outer ends of these plates are bent inward into an L-shape. The L-shaped extension plates and the outer wall of the longitudinal keel 40 form a groove structure, which is the limiting groove 41, and the two limiting grooves 41 are symmetrically arranged. Based on this structural design, when assembling the base 35, the horizontal positioning of the base 35 and the longitudinal keel 40 can be achieved by embedding the two sides of the base 35 into the left and right limiting grooves 41 respectively.

[0093] It should be understood that the design of the limiting groove 41 in the above example is mainly suitable for easy-to-process and easy-to-form metal keels such as aluminum alloy keels. However, the limiting groove 41 structure described above cannot be applied to pre-formed rectangular steel keels.

[0094] Based on this, in order to adapt to steel keel, in another example, the limiting structure includes a base 42, which is fixedly disposed on the side of the longitudinal keel 40 near the single frame 20, and a limiting groove 41 is formed on the side of the base 42 near the single frame 20.

[0095] For example, the base 42 can be a plate-like structure fixed to the outer wall of the longitudinal keel 40 by screws. In this example, the limiting groove 41 is provided on the outer wall of the base 42, and the forming method of the limiting groove 41 can adopt the aforementioned forming method, which will not be repeated here. Based on this structural design, when assembling the base 35, the horizontal positioning of the base 35 and the longitudinal keel 40 can be achieved by embedding the two sides of the base 35 into the left and right limiting grooves 41 respectively. The base 42 is made of an easily formable and easily processed metal material, such as aluminum alloy.

[0096] See Figure 5 In a specific example, the base 42 includes a base plate 422 and connecting plates 421 fixed on both sides of the base plate 422. The base plate 422 is located on the side of the longitudinal keel 40 near the single frame 20. The two connecting plates 421 are located on both sides of the longitudinal keel 40 and are fixedly connected to the side wall of the longitudinal keel 40 by fasteners 43. The limiting groove 41 is formed on the side of the base plate 422 near the single frame 20.

[0097] The limiting groove 41 can be disposed on the surface of the substrate 422 in the same manner as described above, which will not be repeated here. See Figure 3 In this example, the two connecting plates 421 are fixed to both sides of the base plate 422 by integral molding or welding, so that the base 42 forms an "n" shaped structure that can be completely covered on the outside of the longitudinal keel 40.

[0098] See Figure 5 When the base 42 is installed on the longitudinal keel 40, the base plate 422 is parallel to the outer side wall of the longitudinal keel 40 and has a gap. The two connecting plates 421 are located on both sides of the longitudinal keel 40 and are tightly fitted to the left and right side walls of the longitudinal keel 40. The fasteners 43 fix and lock the connecting plates 421 to the side walls of the longitudinal keel 40. Of course, in some embodiments, in order to prevent electrochemical corrosion between two different materials, a second anti-corrosion gasket 44 can also be provided between the connecting plate 421 and the side wall of the longitudinal keel 40.

[0099] Based on the above structure, the fasteners 43 are fixed to the longitudinal keel 40 via the connecting plates 421 on both sides, avoiding the need for fasteners 43 on the base plate 422. This prevents interference between the base 35 and the fasteners 43 on the base plate 422 during assembly. Furthermore, if fasteners 43 are installed on the base plate 422, they are susceptible to simultaneous axial tensile force and radial shear force. However, the fasteners 43 installed on the sides in this invention only bear radial shear force, placing them in the most ideal stress state. Therefore, the structural design of this invention is more reasonable. Moreover, fixing the base 42 to the longitudinal keel 40 via the two connecting plates 421 increases the connection points between the base 42 and the longitudinal keel 40, improving the connection strength and stability between them.

[0100] See Figure 5 In one example, fastener 43 is a connecting screw. Multiple connecting screws are spaced apart along the length of each connecting plate 421 and the longitudinal keel 40, with the spacing between adjacent screws being less than or equal to 300mm. By limiting the spacing between adjacent connecting screws, it can be ensured that each connecting screw is subjected only to radial shear force and not tensile force, placing the connecting screw in an ideal stress state and thus guaranteeing the connection strength between the connecting plate 421 and the longitudinal keel 40.

[0101] See Figure 3 In this embodiment, the connecting arm 33 is a plate-shaped structure and is fixed to the base 35 by integral molding or welding. The connecting arm 33 and the base 35 are arranged perpendicular to each other to ensure the connection strength between the connecting arm 33 and the base 35.

[0102] See Figure 3 In some embodiments, a reinforcing rib 34 is welded to or integrally formed on the connecting arm 33. The reinforcing rib 34 extends along the length of the connecting arm 33 and can enhance the strength of the connecting arm 33 and improve the reliability of the supporting component 30.

[0103] See Figure 3In this embodiment, the upper hook 31 and the lower hook 32 are fixed to the side of the connecting arm 33 away from the base 35 by integral molding or welding, so as to realize the connection between the upper hook 31 and the lower hook 32 and the base 35.

[0104] For example, a plate is welded to the side of the connecting arm 33 away from the base 35. This plate is perpendicular to the connecting arm 33 to ensure the connection strength between the connecting arm 33 and the plate. The upper half of the plate extends upward to above the connecting arm 33, and the lower half extends below the connecting arm 33, so that the plate and the connecting arm 33 form a "T"-shaped hook. The upper half of the "T"-shaped hook is the upper hook 31, and the lower half of the "T"-shaped hook is the lower hook 32.

[0105] It should be understood that in the existing technology, photovoltaic curtain walls usually include multiple horizontally arranged keels, and the mounting components 30 are arranged on the horizontal keels. However, since the existing horizontal keels are pre-installed on the vertical keels by welding or mechanical connection, the height of the horizontal keels cannot be adjusted when installing the photovoltaic curtain wall. Moreover, construction errors are inevitable during the installation of the horizontal keels, which can easily lead to installation errors of the photovoltaic components 10 mounted on each horizontal keel. This results in differences in the longitudinal spacing between the photovoltaic components 10, poor uniformity, and poor installation effect.

[0106] In this embodiment, the horizontal keel design is eliminated, and the mounting component 30 is directly set on the vertical keel 40. During the installation of the photovoltaic curtain wall, the height of the mounting component 30 can be adjusted according to construction needs, and this height adjustment can be arbitrarily adjusted along the length of the vertical keel 40, with a large adjustment range. In this way, the photovoltaic modules 10 of each layer can be kept flush, resulting in high installation accuracy and good effect. Moreover, during installation, one layer of photovoltaic modules 10 can be installed before installing the next layer of mounting component 30, and the height of the mounting component 30 can be adjusted according to the gap between the upper and lower layers of photovoltaic modules 10, reducing installation errors and ensuring a tight connection between the upper and lower layers of photovoltaic modules 10, thereby improving the uniformity and aesthetics of the gaps between photovoltaic modules on the exterior facade of the photovoltaic curtain wall.

[0107] In this embodiment, the mounting assembly includes multiple individual frames 20, which are arranged in a rectangular array and mounted on various supporting components 30. Each pair of adjacent rows of individual frames 20 corresponds to a longitudinal keel 40, and each pair of vertically adjacent individual frames 20 corresponds to a supporting component 30. In this embodiment, the individual frames 20 are used to mount photovoltaic modules 10, thus allowing multiple photovoltaic modules 10 to be mounted in an array on the building's exterior wall to form a photovoltaic curtain wall.

[0108] Specifically, see Figure 2In this embodiment, the upper and lower edges of the single frame 20 are respectively provided with an upper hanger 28 and a lower hanger 21, so that the single frame 20 can be connected to the supporting component 30 through the upper hanger 28 and the lower hanger 21.

[0109] In this embodiment, the upper bracket 28 and the lower bracket 21 can be installed on the upper and lower edges of the single frame 20 by means of snap-fitting, welding, or other methods. In this embodiment, it is preferable that the upper bracket 28 and the lower bracket 21 are snap-fitted with the upper and lower edges of the single frame 20. This allows for quick installation and removal of the upper bracket 28 and the lower bracket 21, making the operation simpler and facilitating on-site construction and installation.

[0110] For example, the inner sides of both the upper and lower frames of the single frame 20 are provided with engaging parts, and both the upper hanger 28 and the lower hanger 21 are provided with engaging mating parts. The upper hanger 28 engages with the engaging part of the upper frame of the single frame 20 through the engaging part, and the lower hanger 21 engages with the engaging part of the lower frame of the single frame 20 through the engaging part. In this way, the engaging parts and mating parts can achieve a stable connection between the upper hanger 28 and the lower hanger 21 and the upper and lower frames of the single frame 20, and also facilitate the quick installation and disassembly of the upper hanger 28 and the lower hanger 21, which is beneficial for on-site operation and construction.

[0111] See Figure 6 In this embodiment, the engaging part is a T-shaped engaging groove 25, and the engaging mating part is a T-shaped engaging member 26 that matches the T-shaped engaging groove 25.

[0112] See Figure 6 The T-shaped locking groove 25 is located on the inner side of the upper and lower frame sides of the single frame 20. The T-shaped locking groove 25 can extend along the length of the upper and lower frame sides and axially penetrate them to form a through groove, facilitating the installation and removal of the upper hanger 28 and the lower hanger 21. In other embodiments, the T-shaped locking groove 25 can also be located at both ends of the upper and lower frame sides, with its length equal to the length of the T-shaped locking member 26, so that the T-shaped locking member 26 can be precisely locked into the T-shaped locking groove 25, and also achieve axial limiting of the T-shaped locking member 26, improving the stability of the mounting.

[0113] See Figure 6 Among them, the T-shaped snap-fit ​​component 26 is a T-shaped structure that is adapted to the T-shaped groove, so that the T-shaped snap-fit ​​component 26 can be snapped into the T-shaped groove.

[0114] See Figure 6In this embodiment, the T-shaped snap-fit ​​26 can be fixed to the outer wall of the upper hanger 28 and the lower hanger 21 by integral molding or welding, and the T-shaped snap-fit ​​26 extends along the length direction of the upper hanger 28 and the lower hanger 21. For example, the T-shaped snap-fit ​​26 can extend from one end of the upper hanger 28 and the lower hanger 21 to the other end, so that the length of the T-shaped snap-fit ​​26 is equal to the length of the upper hanger 28 and the lower hanger 21. In this way, the T-shaped snap-fit ​​26 and the T-shaped groove can have a sufficiently long mating length, the snap-fit ​​area is larger, and the snap-fit ​​stability is improved.

[0115] Of course, in other embodiments, the engaging part can also be a trapezoidal groove, a cross groove, etc. Correspondingly, the engaging mating part can be a trapezoidal part, a cross part, etc.

[0116] The upper hanging part 28 is provided with an upper hanging groove 29, and the lower hanging part 21 is provided with a lower hanging groove 27.

[0117] Specifically, see Figure 6 In this embodiment, both the upper hanger 28 and the lower hanger 21 are n-shaped structures, so that both the upper hanger 28 and the lower hanger 21 have an open slot structure, which is the upper (lower) mounting slot.

[0118] See Figure 2 In this embodiment, when the upper hanging member 28 is snapped onto the upper edge of the single frame 20 by the T-shaped snap-fit ​​member 26, the opening of the upper hanging slot 29 faces upward; when the lower hanging member 21 is snapped onto the lower edge of the single frame 20 by the T-shaped snap-fit ​​member 26, the opening of the lower hanging slot 27 faces downward.

[0119] Based on this, when mounting the single frame 20 on the mounting component 30, the lower hanging piece 21 on the lower edge of the single frame 20 is connected to the upper hook 31 of the mounting component 30 located below it through the lower mounting groove 27, and the upper hanging piece 28 on the upper edge of the single frame 20 is connected to the lower hook 32 of the mounting component 30 located above it through the upper mounting groove 29, so that the mounting of the single frame 20 and the mounting component 30 can be realized.

[0120] In the above structural design, the gravitational load of the single frame 20 is borne by the lower hanger 21 and the upper hook 31, while the radial load (e.g., wind load) of the single frame 20 is borne jointly by the upper hanger 28 and the lower hook 32. The force transmission path is clear, the force distribution mode is reasonable, and the reliability of the single frame 20 installation is ensured. Furthermore, using the lower hanger 21 as a load-bearing component allows the single frame 20 to support the photovoltaic module 10 from bottom to top, resulting in better load-bearing stability.

[0121] Furthermore, in existing technologies, the mounting slots of the upper and lower brackets 21 of the single frame 20 are typically designed with openings facing downwards. This allows the single frame 20 to be mounted to the support via the upper bracket 28 or the lower bracket 21. However, because the upper and lower brackets 21 are both hung from the top down on the support in this structural design, the single frame is prone to jumping off and falling when subjected to upward forces (such as earthquakes), posing a safety hazard. To eliminate this safety hazard, existing technologies typically use anti-jump devices or screws to fix the brackets to prevent the upper and lower brackets 21 from falling off. However, this complicates the structure of the bracket system and makes installation more cumbersome.

[0122] In this embodiment, the lower hanger 21 is attached to the upper hook 31 to achieve the lower limit of the single frame 20, while the upper hanger 28 and the lower hook 32 are inserted to achieve the upper limit of the single frame 20. This prevents the single frame 20 from jumping upwards or sinking downwards, ensuring it is stably secured between the upper and lower load-bearing components. This guarantees good positioning reliability of the single frame 20 in the longitudinal direction, resisting radial and longitudinal loads. Furthermore, in this embodiment, the upper and lower limits of the single frame 20 are achieved solely through the cooperation of the hanger and hook. Compared to existing technologies, this embodiment reduces the need for anti-jump components and fixing structures, resulting in a simpler structure, easier installation, and better mounting reliability.

[0123] See Figure 2 In some embodiments, a longitudinal gap is provided between the lower end of the lower hook 32 and the lower end of the upper mounting groove 29. This longitudinal gap allows for longitudinally adjustable space between the upper and lower single frames 20, absorbing errors generated during installation and providing better fault tolerance.

[0124] See Figure 2 In some embodiments, noise-reducing rubber strips 61 are provided between the lower hanging piece 21 and the upper hook 31, and between the upper hanging piece 28 and the lower hook 32. This can increase the friction between the hanging piece and the hook, improve the stability of the hanging, and also prevent noise from occurring at the metal engagement position when the wind blows.

[0125] See Figure 1 In this embodiment, two upper hanging parts 28 are provided on the upper frame of the single frame 20. The two upper hanging parts 28 are distributed at both ends of the upper frame, and two adjacent upper hanging parts 28 on two horizontally adjacent single frames 20 are hooked to the same lower hook 32. Two lower hanging parts 21 are provided on the lower frame of the single frame 20. The two lower hanging parts 21 are distributed at both ends of the lower frame, and two lower hanging parts 21 on the ends of two horizontally adjacent single frames 20 that are close to each other are hooked to the same upper hook 31.

[0126] Specifically, see Figure 1In this embodiment, the two ends of the upper hook 31 and the lower hook 32 extend to the inner side of two adjacent single frames 20 in the left and right directions, respectively, so that the left half of the upper hook 31 and the lower hook 32 are opposite to the left single frame 20, and the right half of the upper hook 31 and the lower hook 32 are opposite to the right single frame 20. In this way, the upper hanging piece 28 at the right end of the left single frame 20 and the upper hanging piece 28 at the left end of the right single frame 20 can be hooked to the same lower hook 32. Similarly, the lower hanging pieces 21 of two adjacent single frames 20 can be hooked to the same upper hook 31.

[0127] Based on the above structure, by extending the upper hook 31 and lower hook 32 to both sides to form support members of a certain length, similar to the function of the transverse keel, it is possible to connect two adjacent single frames 20 in the transverse direction with good connection stability. Moreover, compared with the transverse keel, the upper hook 31 and lower hook 32 of this embodiment have the advantage of longitudinal adjustment, which can make the upper and lower adjacent single frames 20 tightly connected and the installation effect better.

[0128] In this embodiment, the single frame 20 is formed by a number of single frame 201. Adjacent single frame 201 are connected by corner keys 22. Each single frame 201 is provided with a slot 23 matching the photovoltaic module 10 on the side away from the mounting component 30. A T-shaped slot 25 is provided on the side of the single frame 201 away from the slot 23.

[0129] Specifically, in this embodiment, the single-unit frame 20 includes four single-unit side frames 201, which are joined end to end to form a rectangular frame structure, making the shape of the single-unit frame 20 consistent with the photovoltaic module 10. See also... Figure 2 and Figure 6 The individual frame 201 has a connecting cavity 24 inside. The connecting cavity 24 extends through the individual frame 201 along the length direction. The connecting cavities 24 of two adjacent individual frames 201 are connected by corner keys 22. The corner key 22 is a conventional connector of the frame. Its structure will not be described in detail in this embodiment. For example, the corner key 22 can be the corner key disclosed in CN204271989U.

[0130] The four individual borders 201 have the same structure, see [link / reference]. Figure 6 Each individual frame 201 has a slot 23 on its outer side. In this way, the four sides of the photovoltaic module 10 can be snapped into place by the slots 23 on the four individual frames 201, so that the photovoltaic module 10 is snapped into place and positioned in the individual frame 20.

[0131] See Figure 6The T-shaped slot 25, which cooperates with the T-shaped card connector 26, is located on the side of the single frame 201 away from the slot 23. In this way, the photovoltaic module 10 is hung on the outside of the single frame through the slot 23, and the photovoltaic module 10 is hung on the support component 30 on the inside of the single frame 20 through the upper hanger 28 and the lower hanger 21, thereby realizing the mounting of the photovoltaic module 10 on the longitudinal keel 40.

[0132] See Figure 1 and Figure 2 The joints between adjacent photovoltaic modules 10 can be sealed with sealant 50 to ensure that the entire facade is a complete sealed surface with good waterproof and leak-proof performance.

[0133] In this embodiment, the photovoltaic module 10 is a BIPV (Building Integrated PV) module, realizing the integrated installation of photovoltaic buildings. In existing building curtain wall technologies, stone is usually used as the facade decoration material. However, the process of stone mining, cutting, and slab processing generates a large amount of carbon emissions, causing environmental damage and pollution. This application uses BIPV modules instead of conventional building stone, which not only reduces carbon emissions and environmental pollution, but also increases the application scenarios for photovoltaic modules on building facades, expanding the installed capacity of building photovoltaics. At the same time, most conventional curtain wall panels are made of natural stone, and color differences are inevitable between different batches of natural stone. Quality control can reduce color differences, but cannot eliminate them. However, this application uses BIPV modules as wall panels, which can produce different effects such as color, imitation stone, imitation aluminum panels, and 3D patterns, with richer styles, wider application scenarios, and also improve the aesthetics of building facades to a certain extent. In particular, the imitation stone BIPV photovoltaic module has an appearance that is very close to that of conventional stone. However, the deviation and color difference of the imitation stone BIPV photovoltaic module are very small. It can perfectly replace conventional natural stone to play a decorative role on the exterior of buildings, and solve the carbon emissions and environmental pollution caused by the stone mining and processing process.
