Description
Technical Field
[0001] The utility model belongs to the technical field of solar photovoltaic, and particularly relates to a flexible photovoltaic module applicable to a color steel tile roof. Background Art
[0002] With the progress of technology, solar photovoltaic modules are no longer limited to the traditional rigid form, and "soft" photovoltaic modules are gradually becoming the new favorites in the new energy field. This new type of module is not only portable and foldable, but also shows great application potential in many fields. Currently, flexible modules are mostly applied to building roofs, especially color steel tile roofs with requirements for load-bearing. At present, there are two installation methods for flexible modules: the first is to use special glue for pasting, such as industrial structural glue; the second is to drill holes on the original building roof and fix the flexible module on the building roof through nuts. The above installation methods each have defects. Installing and fixing flexible modules with special glue is convenient for initial installation, but is not conducive to later maintenance. The disassembly work of flexible modules is very troublesome. Since flexible modules are installed on building roofs, there are high requirements for the bonding force of structural glue, which leads to mostly violent disassembly during disassembly. At the same time, there is still residual glue left after disassembly, and secondary cleaning and maintenance are very inconvenient. And the installation method of drilling holes on the building roof will damage the roof, reduce the designed load-bearing capacity of the roof, and even cause potential safety hazards to the entire building.
[0003] In addition, the prior art also mentions the design of a clamping installation structure, that is, using a split installation member and using multiple installation buckles on one side of the photovoltaic module to achieve fixed installation of the flexible module, avoiding drilling holes on the color steel tile for installation. The prior art ignores the gentle characteristics of the flexible module itself. When the flexible module is subjected to external force, the degree of deformation is much greater than that of a conventional crystalline silicon glass module, and the installation buckle only locks a small area on the edge of the flexible module. When the external force is too large, it is easy to tear from the edge of the buckle or pull out from the buckle, resulting in damage to the flexible module and affecting the normal operation of the flexible module. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a flexible photovoltaic module applicable to a color steel tile roof with a compact structure, convenient disassembly and assembly, reliable connection and low cost, aiming at the problem that in the prior art, the installation buckle only locks a small area on the edge of the flexible module, and when the external force is too large, the flexible module is easy to tear from the edge of the buckle or pull out from the buckle, resulting in damage to the flexible module and affecting the normal operation of the flexible module. To achieve the above purpose, the utility model can adopt the following technical solutions:

[0006] As a further improvement of the present utility model, the fixing device includes a support member and a pressing block. A plurality of fixing clamps are provided at the bottom of the support member, and a groove is provided at the top of the support member.

Through the cooperation of the connection holes and the screw-nut sets, the detachable connection between the pressing block and the groove is realized; when installing the flexible module, both ends of the flexible module are respectively crimped in the groove through the pressing block.
[0007] As a further improvement of the present utility model, the pressing block adopts a long strip structure; the distance between the screw-nut sets at both ends of the groove is greater than the width of the flexible module, so as to realize that the end part of the flexible module is completely crimped in the groove.
[0008] As a further improvement of the present utility model, the fixing clamp includes a first clamping plate, a second clamping plate, a bolt and a nut. The first clamping plate adopts a structure, the second clamping plate adopts a vertical plate structure. The top of the first clamping plate is fixedly connected to the bottom of the support member. The upper parts of the first clamping plate and the second clamping plate are connected through a bolt and a nut. The lower parts of the first clamping plate and the second clamping plate are nested on the rib. By screwing the nut, the first clamping plate and the second clamping plate are locked on the rib.
[0009] As a further improvement of the present utility model, the flexible module is obtained by encapsulating a flexible front plate, a first encapsulation film, a solar cell, a second encapsulation film and a flexible back plate.
[0010] As a further improvement of the present utility model, both the flexible front plate and the flexible back plate are prepared by using a glass fiber composite or a polyester composite material.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:
[0014] The flexible photovoltaic module applicable to a color steel tile roof of the present utility model realizes the full fixation of the two side lengths of the flexible module by arranging the flexible module on the color steel tile profile along the water drainage direction of the color steel tile profile and pressing both ends of the flexible module into the fixing device respectively. When the flexible module is stressed, the reverse force is fed back to the fixing device through the two side lengths, avoiding the edge tearing problem caused by partial stress. At the same time, the bottom of the fixing device is detachably installed on the rib of the color steel tile profile through a fixing clamp, ensuring that the flexible module will not shift, and realizing the integrated design of photovoltaic building.

[0025] Embodiment
[0026] As Figures 1 to 6 shown, the flexible photovoltaic module applicable to a color steel tile roof of the present utility model includes: a color steel tile profile 100, a fixing device 200, and a flexible module 300; the flexible module 300 is arranged on the color steel tile profile 100 along the water guiding direction of the color steel tile profile 100, and both ends of the flexible module 300 are respectively crimped in the fixing device 200, and the bottom of the fixing device 200 is detachably installed on the rib 101 of the color steel tile profile 100 through a fixing clamp 204.
[0027] In this embodiment, by arranging the flexible module 300 on the color steel tile profile 100 along the water guiding direction of the color steel tile profile 100 and respectively crimping both ends of the flexible module 300 in the fixing device 200, all side lengths on both sides of the flexible module 300 are fixed. When the flexible module 300 is stressed, the reaction force is fed back to the fixing device 200 through the side lengths on both sides, avoiding the problem of edge tearing caused by partial stress; at the same time, the bottom of the fixing device 200 is detachably installed on the rib 101 of the color steel tile profile 100 through the fixing clamp 204, ensuring that the flexible module 300 will not shift, and realizing the integrated design of photovoltaic architecture.
[0028] As Figure 2 、 Figure 3 and Figure 4As shown, the fixing device 200 includes a support member 201 and a pressing block 203. A plurality of fixing clamps 204 are provided at the bottom of the support member 201, and a groove 2011 with an opening on one side is provided at the top of the support member 201. Along the length direction of the groove 2011, screw-nut sets 202 are respectively provided at both ends of the groove 2011. Correspondingly, connection holes 2031 are respectively provided at both ends of the pressing block 203. When the connection holes 2031 at both ends of the pressing block 203 are inserted into the screws of the screw-nut sets 202, the pressing block 203 can be nested into the groove 2011. By tightening the nuts of the screw-nut sets 202, the detachable connection between the pressing block 203 and the groove 2011 is achieved. When installing the flexible component 300, both ends of the flexible component 300 are respectively pressed and connected in the groove 2011 through the pressing block 203, which not only realizes the stable installation of the flexible component 300 but also ensures the convenience of installation and disassembly of the flexible component 300.
[0029] As Figure 2 shown, the pressing block 203 adopts a strip-shaped structure; the distance between the screw-nut sets 202 at both ends of the groove 2011 is greater than the width of the flexible component 300, so as to realize that both ends of the flexible component 300 are completely pressed and connected in the groove 2011, and the overall force on both ends of the flexible component 300 is realized. By adopting non-glue installation, the convenience of disassembly of the flexible component is guaranteed. Only by loosening the nut above the strip-shaped pressing block can the flexible component 300 be disassembled and replaced.
[0030] As Figure 5 shown, the fixing clamp 204 includes a first clamping plate 2041, a second clamping plate 2042, a bolt 2043 and a nut 2044. The first clamping plate 2041 adopts Structure, the second clamping plate 2042 adopts a vertical plate structure, and the first clamping plate 2041 and the second clamping plate 2042 enclose an inverted U-shaped fixture structure. The top of the first clamping plate 2041 is fixedly connected to the bottom of the support member 201. The upper parts of the first clamping plate 2041 and the second clamping plate 2042 are connected by bolts 2043 and nuts 2044. The limiting end of the bolt 2043 is located outside the second clamping plate 2042. The threaded end of the bolt 2043 sequentially passes through the first clamping plate 2041 and the second clamping plate 2042 and is connected to the nut 2044 outside the first clamping plate 2041. By screwing the nut 2044 on the bolt 2043, the distance between the first clamping plate 2041 and the second clamping plate 2042 can be adjusted. The lower parts of the first clamping plate 2041 and the second clamping plate 2042 are nested on the rib 101, and the bolt 2043 is located above the rib 101, that is, no holes are drilled on the rib 101; by screwing the nut 2044, the first clamping plate 2041 and the second clamping plate 2042 can be locked on the rib 101 or loosened from the rib 101. Further, in order to better improve the clamping stability of the fixed fixture 204, the bottoms of the first clamping plate 2041 and the second clamping plate 2042 are set as inclined openings to match the outer contour of the rib 101.
[0031] In this embodiment, the side of the flexible component 300 is placed in the groove 2011 of the support member 201, and the long strip-shaped pressing block 203 and the support member 201 are locked by the screw-nut kit 202, realizing the crimping of the flexible component 300 on the fixing device 200. Two crimping-type fixing devices 200 are installed along the water guiding direction of the color steel tile profile 100 for each flexible component 300, thereby realizing the fixation of the flexible component 300. At the same time, the fixing fixture 204 at the bottom of the support member 201 is used to fix the body of the fixing device 200 on the color steel tile profile 100, preventing the fixing device 200 and the flexible component 300 from shifting, and improving the installation stability of the flexible component 300.
[0032] As Figure 6 shown, the flexible component 300 is obtained by encapsulating a flexible front plate 301, a first encapsulation adhesive film 302, a solar cell 303, a second encapsulation adhesive film 304, and a flexible back plate 305.
[0033] Furthermore, both the flexible front plate 301 and the flexible back plate 305 are prepared from polymer composite materials. For example, they can be prepared by fiberglass composite. In other embodiments, the flexible front plate 301 and the flexible back plate 305 can also be prepared from polyester composite materials. Both the first encapsulation film 302 and the second encapsulation film 304 are made of EVA (Ethylene Vinyl Acetate); in other embodiments, the first encapsulation film 302 and the second encapsulation film 304 can also be made of one or a combination of two of POE (Polyolefin Elastomer, polyethylene octene copolymer) and EPE (Expandable Polyethylene). The solar cell 303 is made of crystalline silicon; in other embodiments, the solar cell 303 can be made of thin film cells. The flexible component 300 of this embodiment has the characteristics of "light" and "flexible" after encapsulation, and its weight is about between 2 and 8 kg.
[0034] In this embodiment, a flexible component 300 and a corresponding installation structure are designed. First, the flexible component body is designed to achieve the characteristics of "light" and "flexible". Then, a crimping type fixing device 200 is designed to ensure that the flexible component 300 is fixed without glue and no drilling is required on the color steel tile profile 100. The fixing device 200 is fixed to the flexible component 300 by means of crimping and clamping. At the same time, since the mechanical strength of the flexible component 300 is much lower than that of the conventional glass material photovoltaic module and the bending deformation is larger, the flexible component 300 is locked along the whole edge by the long strip-shaped pressing block 203, effectively preventing the edge deformation and tearing of the flexible component 300 and improving the use safety of the flexible component 300.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the methods and technical contents disclosed above, or modify it into equivalent embodiments with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the technical solution of the present utility model still fall within the scope of protection of the technical solution of the present utility model.
