[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0039] Reference Figures 1 to 3 , Figure 1 Structural schematic diagrams of a photovoltaic curtain wall 100 provided for some embodiments of this application; Figure 2 Front view assembly drawing of a photovoltaic curtain wall 100 provided for some embodiments of this application; Figure 3 The following is a side view assembly drawing of a photovoltaic curtain wall 100 provided for some embodiments of this application. The photovoltaic curtain wall 100 includes a curtain wall dry-hanging structure 10 and a first photovoltaic panel 20 and a second photovoltaic panel 30 arranged side by side. The first photovoltaic panel 20 and the second photovoltaic panel 30 are both installed on the wall through the curtain wall dry-hanging structure 10.
[0040] The following describes in detail the curtain wall dry-hanging structure 10 of this application embodiment with reference to the accompanying drawings.
[0041] Reference Figures 4 to 7 , Figure 4 for Figure 3 Enlarged view of section A in the middle; Figure 5 A schematic diagram of the structure of the base 1 provided for some embodiments of this application; Figure 6 A schematic diagram of the structure of the first frame 2 provided for some embodiments of this application; Figure 7 This is a structural schematic diagram of the second subframe 3 provided for some embodiments of this application. The curtain wall dry-hanging structure 10 includes a base 1, a first subframe 2, a second subframe 3, and a shielding plate 4.
[0042] The base 1 is used to connect to the wall. The base 1 can be connected to the wall using steel, aluminum alloy profiles, or wood. For example, the base 1 is connected to the wall using an L-shaped angle steel 5.
[0043] The first subframe 2, also known as the upper subframe, is connected to the base 1 and is used to connect the first photovoltaic panel 20.
[0044] The second subframe 3, also known as the lower subframe, is connected to the base 1 and is used to connect the second photovoltaic panel 30. The second photovoltaic panel 30 and the first photovoltaic panel 20 are arranged side-by-side, with the second photovoltaic panel 30 located below the first photovoltaic panel 20.
[0045] The shielding plate 4 is engaged with at least one of the first subframe 2 and the second subframe 3. On the same projection plane perpendicular to the thickness direction of the shielding plate 4, the projection of the shielding plate 4 covers the projection of the gap 40 between the first photovoltaic panel 20 and the second photovoltaic panel 30. It can be understood that because the shielding plate 4 covers the gap 40 between the first photovoltaic panel 20 and the second photovoltaic panel 30, the mounting components such as the base 1 and the subframe are not easily observed from the outside of the photovoltaic curtain wall 100.
[0046] Due to limitations in installation technology, there is a gap 40 between two photovoltaic panels placed side by side. This gap 40 exposes the internal installation structure such as the base 1 and the subframe, affecting the consistency of the interface. In this embodiment, by setting a shielding plate 4 to cover the gap 40, it is not easy to observe the installation components such as the base 1 and the subframe from the outside of the photovoltaic curtain wall 100, which helps to improve the consistency of the interface of the photovoltaic curtain wall 100.
[0047] In some embodiments, along the thickness direction of the shielding plate 4, the shielding plate 4 is spaced apart from the first photovoltaic panel 20 and spaced apart from the second photovoltaic panel 30, and a heat dissipation channel 6 is formed between the shielding plate 4, the first photovoltaic panel 20 and the second photovoltaic panel 30.
[0048] Reference Figure 4 In some embodiments, the first subframe 2 and the second subframe 3 are mirror-symmetrical, with the plane of symmetry parallel to the thickness direction of the baffle plate 4. In other words, the first subframe 2 and the second subframe 3 have the same structure and are symmetrical vertically. With this configuration, the first subframe 2 and the second subframe 3 can be manufactured using a single set of production molds, which helps to reduce production costs.
[0049] In this embodiment, a heat dissipation channel 6 is formed between the shielding plate 4 and the first photovoltaic panel 20 and the second photovoltaic panel 30. This results in a larger contact area between the first photovoltaic panel 20 and the second photovoltaic panel 30 and the air, which helps to ventilate and dissipate heat from the first photovoltaic panel 20 and the second photovoltaic panel 30, extending the service life of the photovoltaic curtain wall 100.
[0050] In some embodiments, the shielding plate 4 is a metal part, and metal has a high thermal conductivity, which can improve the heat dissipation efficiency of the photovoltaic curtain wall 100.
[0051] In some embodiments, the shielding plate 4 is an aluminum plate, which helps to meet the lightweight requirements of the curtain wall dry-hanging structure 10.
[0052] In some embodiments, the first subframe 2 and / or the second subframe 3 are aluminum frames, which helps to meet the lightweighting requirements of the curtain wall dry-hanging structure 10.
[0053] Furthermore, by snapping the cover plate 4 to at least one of the first subframe 2 and the second subframe 3, no additional mounting components are required for the cover plate 4, which helps to simplify the number of components. At the same time, the snapping method can also reduce the assembly difficulty of the cover plate 4.
[0054] Reference Figures 4 to 7 In some embodiments, the first subframe 2 is provided with a first slot 21 on the side facing the second subframe 3, and the second subframe 3 is provided with a second slot 32 on the side facing the first subframe 2. One end of the baffle 4 is inserted into the first slot 21, and the other end is inserted into the second slot 32.
[0055] For example, the opening of the first slot 21 faces downward, the opening of the second slot 32 faces upward, the upper end of the cover plate 4 is inserted into the first slot 21, and the lower end is inserted into the second slot 32.
[0056] Reference Figure 6 In some embodiments, a third slot 22 is provided on the side of the first subframe 2 facing the second subframe 3. The third slot 22 is closer to the base 1 than the first slot 21. The base 1 has a first cantilever 11, which is engaged in the third slot 22. This arrangement allows the first subframe 2 to be stably connected to the base 1.
[0057] Reference Figure 6 and Figure 4 In some embodiments, the first subframe 2 has a second cantilever 23, which separates the first slot 21 and the third slot 22. The free end of the second cantilever 23 has a first guide protrusion 231, which guides the baffle plate 4 to be inserted into the first slot 21 and abut against the baffle plate 4.
[0058] In this embodiment of the application, by providing a first guide protrusion 231 at the free end of the first cantilever 11, the first guide protrusion 231 can reduce the difficulty of the baffle 4 being inserted into the first slot 21, and at the same time improve the connection stability between the baffle 4 and the first subframe 2.
[0059] In one example, the first cantilever 11 extends upward, and the free end of the top of the first cantilever 11 is an expanded arc-shaped end. The first cantilever 11 abuts against the second cantilever 23 through the arc-shaped end of the free end, thereby improving the connection stability between the base 1 and the first subframe 2.
[0060] Reference Figures 4 to 7 In some embodiments, the second subframe 3 has a locking protrusion 31 on the side opposite to the first subframe 2, and the base 1 is provided with a mating groove 12 that engages with the locking protrusion 31. The locking protrusion 31 is engaged in the mating groove 12, and the second locking groove 32 is located on the side of the locking protrusion 31 opposite to the mating groove 12. This arrangement can improve the connection stability between the base 1 and the second subframe 3.
[0061] Reference Figure 4 , Figure 5 and Figure 7 In some embodiments, the protrusion 31 has a pin 34 on the side opposite to the first subframe 2, and the bottom of the mating groove 12 has a slot 13, into which the pin 34 is inserted. This arrangement increases the connection area between the base 1 and the second subframe 3, improving the connection stability between the base 1 and the second subframe 3.
[0062] In some embodiments, the second subframe 3 further includes a first abutting cantilever 35, which abuts against the side of the base 1 facing the shielding plate 4. This arrangement can further improve the connection stability between the second subframe 3 and the base 1, and improve the overall stability of the curtain wall dry-hanging structure 10.
[0063] In some embodiments, a cavity is defined between the first subframe 2, the second subframe 3, the base 1, and the shielding plate 4. The cavity can improve the heat dissipation efficiency of the photovoltaic curtain wall 100.
[0064] Reference Figures 4 to 7In some embodiments, the curtain wall dry-hanging structure 10 includes a base 1, a first subframe 2, a second subframe 3, and a shielding plate 4. The first subframe 2 is used to bond a first photovoltaic panel 20, and the second subframe 3 is used to bond a second photovoltaic panel 30. The first subframe 2 and the second subframe 3 have identical structures and are mirror-symmetrical vertically. The first subframe 2 is located above the second subframe 3. The first subframe 2 has a downwardly extending second cantilever 23 and a second abutting cantilever 24, as well as a downwardly opening first slot 21 and a third slot 22. The second cantilever 23 separates the first slot 21 and the third slot 22, and the second abutting cantilever 24 and the second cantilever 23 define the third slot 22. The second subframe 3 has an upwardly extending first abutting cantilever 35 and a third cantilever 36, as well as an upwardly opening second slot 32 and a fourth slot 33. The third cantilever 36 separates the second slot 32 and the fourth slot 33, and the third cantilever 36 and the first abutting cantilever 35 define the fourth slot 33. The first slot 21 corresponds to the second slot 32, the third slot 22 corresponds to the fourth slot 33, the second cantilever 23 corresponds to the third cantilever 36, and the second abutting cantilever 24 corresponds to the first abutting cantilever 35. The upper end of the baffle plate 4 is inserted into the first slot 21, and the lower end is inserted into the second slot 32. The free end of the second cantilever 23 is provided with a first guide protrusion 231, which guides the baffle plate 4 into the first slot 21 and abuts against the baffle plate 4. The free end of the third cantilever 36 is provided with a second guide protrusion 361, which guides the baffle plate 4 into the second slot 32 and abuts against the baffle plate 4. The second subframe 3 has a locking protrusion 31 on the side opposite to the first subframe 2. The base 1 has a mating groove 12 for the first cantilever 11 and the locking protrusion 31 to engage. The locking protrusion 31 engages in the mating groove 12, and the first cantilever 11 engages in the third slot 22. The free end of the first cantilever 11 is an expanded arc-shaped end, which abuts against the second cantilever 23. The second abutting cantilever 24 abuts against the side of the first cantilever 11 away from the baffle plate 4, and the first cantilever 11 abuts against the side of the base 1 facing the baffle plate 4. The lower subframe also has a pin 34, which is opposite to the first abutting cantilever 35 and extends downward. The bottom of the mating groove 12 is provided with a slot 13, and the pin 34 is inserted into the slot 13.
[0065] In this embodiment of the application, the first subframe 2 and the second subframe 3 have the same structure, which can reduce the number of required component models.
[0066] If the stress concentration caused by the connection between the base 1 and the first subframe 2 and the stress concentration caused by the connection between the base 1 and the second subframe 3 are superimposed in the height direction, it will aggravate the fatigue deformation of the base 1, resulting in a reduction in the overall structural strength of the curtain wall dry-hanging structure 10. In this embodiment, the first subframe 2 and the second subframe 3 are symmetrical structures, while the base 1 is an asymmetrical structure, so that the connection position between the base 1 and the first subframe 2 and the connection position between the base 1 and the second subframe 3 are different. Therefore, the stress concentration caused by the connection between the base 1 and the first subframe 2 and the stress concentration caused by the connection between the base 1 and the second subframe 3 can be alleviated in the height direction, reducing the risk of fatigue deformation of the base 1 and improving the structural strength of the curtain wall dry-hanging structure 10.
[0067] Understandable. Figures 1 to 4 The diagram illustrates a scenario where the dry-hanging structure 10 connects the lower end of the first photovoltaic panel 20 and the upper end of the second photovoltaic panel 30, thereby supporting two adjacent photovoltaic panels. In other embodiments, considering the structural stability of the photovoltaic curtain wall 100, a third sub-frame (not shown) can be provided at the left end of the photovoltaic panel and a fourth sub-frame (not shown) at the right end. The third sub-frame connects to an adjacent photovoltaic panel on the left side of the photovoltaic panel, and the fourth sub-frame connects to an adjacent photovoltaic panel on the right side of the photovoltaic panel. It can be understood that the photovoltaic panel is fixed in place by four sub-frames. This fixing method is particularly suitable for installing photovoltaic panels that are heavy or large in area, thereby improving the structural stability of the photovoltaic curtain wall 100.
[0068] In one example, the third and fourth subframes are mounted to the wall using different mounting brackets.
