[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a waterproof BIPV system. Background Technology

[0002] There are two main types of waterproofing solutions for photovoltaic modules in existing building-integrated photovoltaics (BIPV): one is structural waterproofing, which involves creating a water channel under the photovoltaic module, but the waterproofing effect is generally poor, and some leakage may occur when the rainfall is too heavy; the other type uses silicone sealant for waterproofing, which has a better waterproofing effect, but the construction is more complicated, and it is difficult to replace the photovoltaic module if it is damaged later. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in view of the fact that the waterproof structure of photovoltaic modules has poor waterproof effect, is inconvenient to install and affects the subsequent replacement of photovoltaic modules, the present invention provides a waterproof BIPV system with good waterproof effect, convenient installation and construction and easy subsequent replacement of modules.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A waterproof BIPV system includes photovoltaic modules, drainage rails and waterproof components at junctions. The drainage rails extend longitudinally and are parallel to each other and spaced apart. Each drainage rail has a left side, a right side and a drainage groove between the left and right sides extending along its length. The inner sides of the left and right sides each have an inwardly opening T-shaped groove.

[0006] The photovoltaic module is covered between two adjacent drainage rails on the left and right sides for waterproofing the left and right sides of the photovoltaic module. The lower part of the left side frame of the photovoltaic module is blocked inside the right side of the drainage rail on the same side and is installed on the right side by bolts fasteners that are embedded in the T-slots of the right side. The lower part of the right side frame of the photovoltaic module is blocked inside the left side of the drainage rail on the same side and is installed on the left side by bolts fasteners that are embedded in the T-slots of the left side. The lower part of the left and right side frames of the photovoltaic module has mounting holes for matching bolts fasteners.

[0007] Photovoltaic modules installed between two adjacent left and right drainage rails are arranged in a row to form a photovoltaic module column. The photovoltaic modules that are adjacent vertically connected are waterproofed by a joint waterproof component. The joint waterproof component has an n-shaped cross-section in the horizontal direction, consisting of a top plate and left and right sides of the top plate. In the vertical direction, the joint waterproof component consists of an upper end, a lower end, and a transition part connecting the upper and lower ends. The joint waterproof component covers the two adjacent left and right drainage rails. The left side of the joint waterproof component blocks the inside of the right side of the drainage rail on the same side, and the right side of the joint waterproof component blocks the inside of the left side of the drainage rail on the same side.

[0008] The lower end of the upper photovoltaic module in two adjacent photovoltaic modules covers the outer side of the upper end of the waterproof component at the junction, and the contact surfaces between the two are bonded together. The lower end of the waterproof component at the junction covers the outer side of the upper end of the lower photovoltaic module in two adjacent photovoltaic modules, and the contact surfaces between the two are bonded together.

[0009] Furthermore, the waterproof BIPV system also includes end support plates and module junction support plates. The photovoltaic module only has module frames on the left and right sides.

The upper and lower ends of the support plate are located on the back of the lower end of the upper photovoltaic module and the back of the upper end of the lower photovoltaic module, respectively, to support the ends of the photovoltaic modules. The upper end of the waterproof component at the junction is located between the support plate at the junction of the modules and the photovoltaic module.

[0012] The first and last support plates are set on the back of the lower end of the first photovoltaic module in the photovoltaic module row, or on the back of the upper end of the last photovoltaic module, to support the ends of the photovoltaic modules. The first photovoltaic module refers to the bottom photovoltaic module in the photovoltaic module row.

[0013] The left and right sides of the component junction support plate and the first and last support plates are all installed on the side of the drainage guide rail by bolts and fasteners for mounting the component frame.

[0017] Furthermore, the left and right sides of the photovoltaic module frame have an inverted L-shaped groove on the inner side of the lower part of the back of the photovoltaic module. The upper part of the side of the drainage guide rail is embedded in the inverted L-shaped groove to support the photovoltaic module. The outer side of the inverted L-shaped groove is the vertical fin of the lower part of the module frame. The vertical fin blocks the inner side of the side of the drainage guide rail. The mounting holes of the module frame are located on the vertical fin.

[0018] Furthermore, the left and right sides of the photovoltaic module frame have an inverted L-shaped groove on the inner side of the lower part of the back of the photovoltaic module.

The mounting holes of the module frame are located on the vertical fin.

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0073] Example 1

[0074] Figures 1-23 The waterproof BIPV system shown includes a photovoltaic module 1, a drainage guide rail 2, and a waterproof component 4 at the junction. The drainage guide rail 2 extends longitudinally and is parallel to each other and spaced apart. The drainage guide rail 2 has a left side, a right side, and a drainage groove 21 extending along its length direction. The inner side of the left side and the right side both have T-shaped grooves 22 that open inward.

[0075] The photovoltaic module 1 is covered between two adjacent drainage rails 2 for waterproofing the left and right sides of the photovoltaic module 1. The lower part of the left side frame 11 of the photovoltaic module 1 is blocked inside the right side of the drainage rail 2 on the same side and is installed on the right side by bolt fasteners 3 embedded in the T-slot 22 on the right side. The lower part of the right side frame 11 of the photovoltaic module 1 is blocked inside the left side of the drainage rail 2 on the same side and is installed on the left side by bolt fasteners 3 embedded in the T-slot 22 on the left side. The lower part of the left and right side frame 11 of the photovoltaic module 1 has mounting holes 112 for mounting with matching bolt fasteners 3.

[0076] Photovoltaic modules 1 installed between two adjacent left and right drainage guide rails 2 are arranged in a row to form a photovoltaic module column. The photovoltaic modules 1 that are adjacent vertically are waterproofed by a joint waterproof component 4. The joint waterproof component 4 has an n-shaped cross-section in the horizontal direction and is divided into a top plate and the left and right sides of the top plate. The joint waterproof component 4 is divided into an upper end, a lower end and a transition part connecting the upper end and the lower end in the vertical direction. The joint waterproof component 4 covers the two adjacent left and right drainage guide rails 2. The left side of the joint waterproof component 4 blocks the inside of the right side of the drainage guide rail 2 on the same side, and the right side of the joint waterproof component 4 blocks the inside of the left side of the drainage guide rail 2 on the same side.

[0077] The lower end of the upper photovoltaic module 1 of two adjacent photovoltaic modules 1 covers the outer side of the upper end of the waterproof component 4 at the junction, and the contact surfaces between the two are bonded together. The lower end of the waterproof component 4 at the junction covers the outer side of the upper end of the lower photovoltaic module 1 of two adjacent photovoltaic modules 1, and the contact surfaces between the two are bonded together.

[0078] In this embodiment, the photovoltaic module is a rectangular photovoltaic module, so the module frame on the left and right sides is also called the long frame.

[0079] The waterproof component 4 at the junction between adjacent photovoltaic modules 1 is a waterproof sheet material. In the longitudinal direction, the upper end is small and is used to pad the inner side of the lower end of the upper photovoltaic module 1. There is a transition part in the middle, and the lower end is large and is used to fit the outer side of the upper end of the lower photovoltaic module 1. There is a certain tilt angle between the upper and lower photovoltaic modules 1, which can form a good drainage effect.

[0080] Due to the height difference between two adjacent photovoltaic modules 1, water on the surface of photovoltaic module 1 flows through the waterproof component 4 at the junction to the front of the next photovoltaic module.

[0081] Specifically, the material of the waterproof component 4 at the junction can be a soft material such as TPO, PVC, or asphalt roll, or a hard material such as aluminum plate, stainless steel plate, or PC plate, which is pre-processed into a shape that matches the installation of the photovoltaic module 1.

[0082] Specifically, the bolt fastener 3 includes a T-bolt 31 with one end limiting, flat washers 33 and spring washers 34 located on both sides of the fixing surface, and a nut 32 with the other end limiting and locking. The spring washer 34 is located on the side closer to the nut 32.

[0083] The left and right sides of the photovoltaic module 1 have inverted L-shaped grooves 113 on the inner side of the lower part of the back of the photovoltaic module 1. The upper part of the side of the drainage rail 2 is embedded in the inverted L-shaped grooves 113 to support the photovoltaic module 1. The outer side of the inverted L-shaped grooves 113 is the lower vertical fins 111 of the module frame 11. The vertical fins 111 block the inner side of the side of the drainage rail 2. The mounting holes 112 of the module frame 11 are located on the vertical fins 111. Because the mounting holes 112 are on the side and at the bottom, the waterproof effect on the left and right sides can be guaranteed.

[0084] The photovoltaic module 1 has a module frame 11 on only the left and right sides. The module frame 11 is flush with or slightly exceeds the glass part. Of course, in order to ensure the load performance of the photovoltaic module 1, a reinforcing rib can be added to the back of the photovoltaic module 1. The reinforcing rib is located in the upper part of the module frame 11 and does not exceed the top of the vertical fins 111.

[0085] The waterproof component 4 and the photovoltaic module 1 are bonded together by water-blocking tape 9. The amount of water-blocking tape 9 can be increased or decreased according to the actual installation situation.

[0086] In this embodiment, the waterproofing on the left and right sides of the photovoltaic module 1 is solved by the drainage guide rail 2. The module frame 11 is also specially designed. The module frame 11 and the drainage guide rail 2 are fixed on the lower side, and the fixing part is located inside the drainage groove, which is lower than the highest surface of the drainage groove of the drainage guide rail 2. The waterproofing on the module frame 11 of the photovoltaic module 1 is enhanced by the addition of a waterproof joint 4 that matches the shape of the upper and lower photovoltaic modules. The upper end of the waterproof joint 4 is located inside the upper photovoltaic module, and the lower end of the waterproof joint 4 is located outside the lower photovoltaic module, thus covering the lower photovoltaic module. The drainage problem is completely solved through the above design. Silicone is not required during the process, and it is also convenient to maintain and replace the photovoltaic module in the future.

[0087] The waterproof BIPV system also includes the first and last support plates 6 and the component junction support plate 7. The first and last support plates 6 and the component junction support plate 7 have an n-shaped cross section in the transverse direction, and are divided into a top plate and the left and right sides of the top plate.

[0088] The component junction support plate 7 and the first and last support plates 6 are both covered between two adjacent drainage guide rails 2 on the left and right. The left side of the component junction support plate 7 and the first and last support plates 6 are blocked inside the right side of the drainage guide rail 2 on the same side. The right side of the component junction support plate 7 and the first and last support plates 6 are blocked inside the left side of the drainage guide rail 2 on the same side.

[0089] The component junction support plate 7 is located between the upper and lower adjacent photovoltaic modules 1. The upper end and lower end of the component junction support plate 7 are located on the back of the lower end of the upper photovoltaic module 1 and the back of the upper end of the next photovoltaic module 1, respectively, to support the end of the photovoltaic module 1. The upper end of the junction waterproof component 4 is located between the component junction support plate 7 and the photovoltaic module 1.

[0090] The first and last support plates 6 are located on the back of the lower end of the first photovoltaic module 1 in the photovoltaic module row, or on the back of the upper end of the last photovoltaic module 1, to support the ends of the photovoltaic modules 1. The first photovoltaic module 1 refers to the bottom photovoltaic module 1 in the photovoltaic module row.

[0091] The left and right sides of the component junction support plate 7 and the first and last support plates 6 are installed on the side of the drainage guide rail 2 by bolts and fasteners 3 for mounting the component frame 11. The left and right sides of the component junction support plate 7 and the first and last support plates 6 have mounting holes for matching bolts and fasteners 3.

[0092] Since the lower end of the support plate 7 at the junction of the components is in direct contact with the photovoltaic module 1, a buffer pad 10 is set between them for buffering; the first and last support plates 6 are also in direct contact with the photovoltaic module 1, so a buffer pad 10 is set between them for buffering.

[0093] The waterproof BIPV system also includes mounting base beams 5 for installation with the mounting base. The mounting base beams 5 extend laterally and are parallel and spaced apart from each other. Drainage guide rails 2 are mounted on the mounting base beams 5.

[0094] Example 2

[0095] It is basically the same as Example 1, except that: Figures 24-35 As shown, the photovoltaic module 1 has module frames 11 on the top, bottom, left, and right sides. In this embodiment, the photovoltaic module is a rectangular photovoltaic module, so the module frames on the left and right sides are also called long frames, and the module frames on the top and bottom sides are also called short frames.

[0096] The upper end of the waterproof component 4 at the junction is bonded to the lower end of the component frame 11 of the previous photovoltaic module 1, and the lower end of the waterproof component 4 at the junction is bonded to the upper end of the component frame 11 of the next photovoltaic module 1.

[0097] The waterproof BIPV system also includes an upper frame waterproof component 8, which is used for bonding the lower end of the junction waterproof component 4 to the upper end of the photovoltaic module 1. The upper frame waterproof component 8 is bonded or heat-fused to the junction waterproof component 4, and the junction waterproof component 4 is bonded to the module frame 11 at the upper end of the photovoltaic module 1.

[0098] The left and right side frame 11 of the photovoltaic module 1 has an inverted L-shaped groove 113 on the inner side of the lower part of the back of the photovoltaic module 1. The upper part of the side of the drainage rail 2 is embedded in the inverted L-shaped groove 113 to support the photovoltaic module 1. The outer side of the inverted L-shaped groove 113 is the lower vertical fin 111 of the frame 11. The vertical fin 111 blocks the inner side of the side of the drainage rail 2. The mounting hole 112 of the frame 11 is located on the vertical fin 111. The top of the inverted L-shaped groove 113 of the left and right side frame 11 of the photovoltaic module 1 is flush with or protrudes from the bottom of the upper and lower side frame 11 of the photovoltaic module 1.

[0099] Both the upper frame waterproof component 8 and the junction waterproof component 4 are made of high-polymer flexible waterproof materials. TPO, PVC, asphalt and other waterproof materials that can be hot-air welded can be used. Simply overlap the upper frame waterproof component 8 and the junction waterproof component 4 and then hot-air weld them together to achieve waterproofing, avoiding the need for adhesive construction.

[0100] If the materials of the upper frame waterproof component 8 and the junction waterproof component 4 cannot or do not wish to be hot-air welded, then sealant can be used to bond the two together.

[0101] Of course, the upper frame waterproof component 8 can be omitted. During construction, the waterproof component 4 at the junction can be directly bonded to the frame of the next photovoltaic module 1 using sealant.

[0102] In this embodiment, the waterproof joint component 4, the upper frame waterproof component 8, and the module frame 11 of the photovoltaic module 1 can be pre-installed together in the factory using sealant. During module installation, the waterproof joint component 4 is fastened onto the upper frame waterproof component 8, and then the photovoltaic module is locked through the mounting holes 112 on the sides of the module frame and the drainage guide rail 2. Finally, the upper frame waterproof component 8 and the waterproof joint component 4 are bonded together by heating or by applying sealant between them to achieve waterproofing. There is a certain tilt angle between the upper and lower photovoltaic modules 1. This design allows for effective drainage. Rainwater flows from the outer glass surface of the previous photovoltaic module 1 through the waterproof joint 4 to the next photovoltaic module 1, or from the side into the drainage rail 2. Through this structural optimization, the waterproofing effect is significantly improved. Furthermore, both the waterproof joint 4 and the upper frame waterproof joint 8 are made of flexible materials. If the module needs to be disassembled and replaced later, it is only necessary to cut off the waterproof joint 4 and the upper frame waterproof joint 8 to replace the photovoltaic module. It is also relatively easy to remove the silicone sealant after prying it apart from the waterproof joint 4 and the upper frame waterproof joint 8.

[0103] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
