Description

Technical Field

[0001] This utility model relates to the field of building-integrated photovoltaics (BIPV) technology, specifically to a sealed and waterproof photovoltaic roofing integrated system. Background Technology

[0002] Installing photovoltaic (PV) modules on rooftops is a common practice in green building. Current technology typically treats the roof structure and PV modules as two separate systems: the roof structure is constructed first, and then the PV modules are installed. This usually involves installing "W" or "M" shaped steel drainage brackets on the roof to fix the PV modules to the brackets, which then facilitate drainage. This existing structural setup and construction method has the following drawbacks:

[0003] 1. The roof structure and photovoltaic modules are two separate systems, resulting in high construction costs;

[0004] 2. The installation of photovoltaic modules can easily damage the waterproof layer of the roof structure, posing a potential risk of roof leaks;

[0005] 3. The drainage cross-section of the water guide bracket is small, and the water guide channel inside the water guide bracket is very prone to overflow, which can cause large-area water leakage on the roof.

[0006] 4. Photovoltaic modules often use close-fitting installation of photovoltaic panels, resulting in large gaps at the joints. This lack of sealing makes them susceptible to leaks in the photovoltaic roof and microcracks in the photovoltaic modules and panels due to temperature expansion and contraction stress and module deformation. Utility Model Content

The upper horizontal plate is connected to the upper end of the vertical plate, and the lower horizontal plate is connected to the lower end of the vertical plate. The upper and lower horizontal plates are located on both sides of the vertical plate. The outer edge of the upper horizontal plate is bent downward to form an upward-turned rib. The outer edge of the lower horizontal plate is first bent upward and then bent horizontally outward to form a horizontal support plate. The height of the horizontal support plate is lower than the height of the upper horizontal plate.

[0046] The structure of the metal plate water tank 9 is as follows Figure 1 and Figure 4 As shown, the metal plate water tank 9 has a horizontal bottom plate and side wings located on both sides of the horizontal bottom plate. The side wing near the structural support 8 has its top bent diagonally downward to the right to form a folded edge.

[0047] The structure of the sealing base pad 3 is as follows Figure 6 As shown, the sealing base pad 3 includes an upper plate 31. The left side of the upper plate 31 is bent downward to form a base pad flange rib 32, and the right side of the upper plate 31 is bent to form a base pad waterproof edge rib 33. The shape of the base pad waterproof edge rib 33 is similar to the shape of the edge rib 213 of the sealing edge 2. The purpose is to ensure that after the sealing base pad 2 and the sealing edge 2 are installed together, the base pad waterproof edge rib 33 and the edge rib 213 can be connected and have a through cavity. The top of the base pad waterproof edge rib 33 forms a recessed rubber strip caulking groove 34. The base pad sealing rubber strip 35 is installed in the rubber strip caulking groove 34. The height of the base pad sealing rubber strip 35 is flush with or slightly higher than the top surface of the upper plate 31.

[0048] like Figure 1 As shown, in this embodiment, multiple sets of photovoltaic modules 4 are arranged on the roof. Each set of photovoltaic modules 4 mainly consists of a photovoltaic panel 41 and a frame 42 (e.g., Figure 11(As shown). In each group of photovoltaic modules 4, the photovoltaic panel 41 is a whole photovoltaic panel 41. Each of the two opposite sides of one group of photovoltaic panel 41 is provided with a frame 42. The frame 42 is long and narrow and is used to fix the photovoltaic panel 41.

[0049] The connection structure between the main components given above is described below: (Refer to...) Figure 1 As shown, structural supports 8 are fixedly installed at two opposite ends of the roof. A metal plate water trough 9 is also installed at each end of the structural support 8. The length directions of the structural supports 8 and the metal plate water trough 9 are consistent, and they are arranged parallel to each other. Sealing edge pieces 2 are spaced apart on each end of the structural support 8, with their length directions consistent with the length direction of the structural support 8. Adjacent sealing edge pieces 2 on each end of the structural support 8 are joined by sealing base pads 3, the length of which is shorter than that of the sealing edge piece 2. Sealing water guide brackets 1 are spaced apart between the two ends of the structural supports 8, with their length directions perpendicular to the length direction of the structural support 8. The two ends of each sealing water guide bracket 1 are placed on the corresponding sealing base pads 3 on the structural support 8. Every two adjacent sealing water guide brackets 1 and the two corresponding sealing edge pieces 3 at each end form a rectangular frame unit. A set of photovoltaic modules 4 is installed on the upper part of each frame unit. When installing the photovoltaic modules 4, the length direction of the frame 42 is aligned with the length direction of the sealing water guide bracket 1.

[0050] When the sealing edge trim 2 is installed with the structural bracket 8, if Figure 4 As shown, the horizontal plate 211 is placed on top of the upper horizontal plate of the structural support 8, and the edge trim rib 212 is made to fit against the upper edge trim rib of the structural support 8. The folded edge of the metal plate water tank 9 is snapped into the waterproof edge trim rib 213 of the edge trim. The horizontal support plate of the structural support 8 is used to support the horizontal bottom plate of the metal plate water tank 9, so that the sealing strip 24 of the edge trim is tightly attached to the bottom surface of the photovoltaic panel 41.

[0051] When the sealing base pad 3 is installed with the structural bracket 8, if Figure 5 As shown, the upper plate 31 is placed on top of the upper horizontal plate of the structural support 8, so that the bottom support pad flange 32 fits against the upper flange rib of the structural support 8, and the sealing bottom support pad 3 can be flush with the sealing edge pieces 2 on both sides. The folded edge of the metal plate water tank 9 is snapped into the waterproof edge rib 33 of the bottom support pad, so that the top of the bottom support pad sealing strip 35 is tightly fitted with the bottom surface of the horizontal bottom plate 11 of the sealing water guide bracket 1.

[0052] The sealing edge trim 2 is vertically and fixedly connected to the sealing water guide bracket 1, such as... Figure 7 and Figure 8 As shown, the sealed water guide bracket 1 and the sealed edge trim 2 are connected by a frame assembly 5, the structure of which is as follows: Figure 9As shown, the frame assembly 5 includes a vertical connecting piece 52 and a sliding rib 51 located on the right side of the connecting piece 52. The thickness of the sliding rib 51 is greater than the thickness of the connecting piece 52. The upper and lower ends of the connection between the connecting piece 52 and the sliding rib 51 are recessed to form sliding rib grooves 53. Fixing holes are provided on the connecting piece 52. When installing the frame assembly 5, the upper and lower ends of the sliding rib 51 are respectively embedded into the upper and lower rib plate connecting grooves 16 of the sealing water guide bracket 1. The installation position can be easily adjusted by sliding the sliding rib 51 along the rib plate connecting grooves 16. After the position is adjusted, the connecting piece 52 is attached to the outward-facing side of the vertical rib 22 of the sealing edge trim 2 and fixed with bolts. A snap fastener 6 is provided on the other side of the vertical rib 22. The structure of the snap fastener 6 is as follows: Figure 10 As shown, the snap fastener 6 includes a horizontal pressure plate 61 and a snap fastener groove 62 located on the right side of the horizontal pressure plate 61. The snap fastener groove 62 is open downwards, and a fixing hole is provided on the horizontal pressure plate 61. When installing the snap fastener 6, as follows... Figure 8 As shown, the snap-fit ​​groove 62 is engaged with the rib connecting groove 16 at the lower part of the side vertical rib plate 12. The relative sliding of the snap-fit ​​groove 62 and the rib connecting groove 16 facilitates the adjustment of the position. After the adjustment is in place, the horizontal pressure plate 61 is placed on top of the horizontal plate 211 of the sealing edge piece 2, and the horizontal pressure plate 61, the horizontal plate 211 and the upper horizontal plate of the structural support 8 are fixed together with bolts.

[0053] The frame 42 of the photovoltaic module 4 is mounted on the sealed water guide bracket 1 via the connecting component 7, as shown below. Figure 11 As shown, the connecting assembly 7 includes a connecting screw 71, a base support 72, and a pressure block 73. The pressure block 73 includes a base plate, with both sides bent upwards and then horizontally outwards to form flanges. The flanges are higher than the base plate, and holes are opened on the base plate. The structure of the base support 72 is as follows... Figure 12As shown, the base support 72 includes a horizontal support plate 724. The bottom surface of the horizontal support plate 724 is provided with perpendicular limiting ribs 721 spaced apart from the horizontal support plate 724, and the top surface of the horizontal support plate 724 is provided with perpendicular component limiting ribs 722 spaced apart from the horizontal support plate 724. Bolt holes 723 are opened on the horizontal support plate 724 between the two component limiting ribs 722. The horizontal support plate 724 of the base support 72 is placed on top of the middle connecting rib 14 of the sealed water guide bracket 1, with the two limiting ribs 721 located outside the middle connecting rib 14. The top of the same sealed water guide bracket 1 is used to place the frames 42 of two sets of photovoltaic modules 4 at adjacent ends. That is, a frame 42 of a photovoltaic module 4 is provided at each end of the top of the horizontal support plate 724, with the bottom surface 421 of the frame resting on the horizontal support plate 724 outside the component limiting ribs 722. The pressure block 73 is disposed between two adjacent frame 42. The pressure block 73 is located on the upper part of the bottom support 72, so that each side flange of the pressure block 73 presses against the top of the corresponding side frame 42. The connecting screw 71 passes through the openings on the pressure block 73 and the bottom support 72 and extends into the connecting groove 141 of the sealing water guide bracket 1. Nuts are respectively fitted on the connecting screw 71 on the upper part of the pressure block 73 and the connecting screw 71 on the lower part of the bottom support 72. The nuts located in the connecting groove 141 can be limited by the connecting groove 141 to prevent them from coming out.

[0054] The photovoltaic roof integrated system is installed according to the above-described structure of this utility model. It can be seen that rainwater flowing from the water channel of the sealed water guide bracket 1 can fall into the metal plate water channel 9. The drainage cross-section of the metal plate water channel 9 is much larger than that of the sealed water guide bracket 1, which can improve the problem of large-area leakage caused by overflow from the water channel of the sealed water guide bracket 1. This utility model uses unit-type photovoltaic modules 4 for arrangement. Each group of photovoltaic modules 4 is waterproofed by corresponding sealing strips around its perimeter. Leakage at the joints between adjacent groups of photovoltaic modules 4 can be discharged into the metal plate water channel 9 along the water channel of the sealed water guide bracket 1, preventing leakage and water accumulation. The photovoltaic modules 4 combine power generation and roof functions, reducing overall construction costs. The entire integrated system is assembled by disassembling various components, improving construction and assembly efficiency and significantly reducing photovoltaic operation and maintenance costs.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
