Description

Technical Field

[0001] This utility model relates to the field of rooftop photovoltaic system technology, specifically to an integrated roofing system of profiled steel sheet and photovoltaic module. Background Technology

[0002] Photovoltaic buildings combine photovoltaic modules with building materials and apply them directly to the building envelope, such as roofs and walls. Photovoltaic buildings have both power generation and building functions and are widely used.

[0003] Building surfaces are typically covered with profiled steel sheets, and photovoltaic (PV) modules are fixed to the seams of these sheets using clamps. However, current technology makes it difficult for these clamps to ensure a perfect fit between the PV modules and the corrugated surfaces of the steel sheet. This results in extremely poor stability for the PV modules, making them highly susceptible to loosening due to strong winds or instability, potentially leading to tipping over. To further improve the stability of the installed PV modules, workers often use bolts to fix them to the top outer wall of the profiled steel sheet. However, directly fixing the PV modules to the steel sheet surface with bolts can damage the top of the sheet, leading to potential leaks during the rainy season. Therefore, there is an urgent need for an integrated roofing system combining profiled steel sheets and PV modules to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background, the present invention provides an integrated roofing system of profiled steel sheet and photovoltaic module.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A roofing system integrating profiled steel sheet and photovoltaic module includes a steel sheet body and a fixing frame disposed on the top of the steel sheet body. A photovoltaic panel is fixedly connected inside the fixing frame. A protruding rib is provided on the top of the steel sheet body, and a fixing seat is provided on the top of the protruding rib.

[0007] Locking plates are provided on both sides of the fixing base, and the fixing frame is fixedly connected to the locking plates.

[0008] As a further embodiment of this utility model: the fixing base includes a rectangular part and a positioning part fixedly connected to the top of the protruding ridge, and a supporting part is fixedly connected to the top of the rectangular part. The cross-section of the supporting part is an inverted isosceles trapezoid.

[0009] As a further embodiment of this utility model: the locking plate includes a horizontal part, an inclined part and a snap-fit ​​part, the snap-fit ​​part snaps into the interior of the positioning part, one side of the outer wall of the inclined part is attached to one side of the outer wall of the support part, and the top of the horizontal part and the top of the support part are located on the same horizontal plane.

[0010] As a further embodiment of this utility model: a first circular hole and a second circular hole are respectively opened on one side of the outer wall of the snap-fit ​​part, and a second fixing screw and a first fixing screw are respectively inserted into the first circular hole and the second circular hole, and both ends of the second fixing screw and the first fixing screw pass through the rectangular part.

[0011] As a further embodiment of this utility model: the two sets of locking plates are locked to the outer walls of both sides of the fixing seat by the first fixing screw and the second fixing screw. There are two sets of the first round holes, and the two sets of the first round holes and the second round holes are distributed in an isosceles triangle on one side of the outer wall of the snap-fit ​​part.

[0012] As a further improvement of this utility model: a threaded hole is provided on the top outer wall of the locking plate, and a fixing bolt is provided on the top of the fixing frame, the fixing bolt being threadedly connected to the threaded hole.

[0013] As a further embodiment of this utility model: another locking plate has a locking hole on its top outer wall, and a positioning post is fixedly connected to the bottom outer wall of the fixing frame. The positioning post passes through the inside of the locking hole, and the cross-section of the positioning post and the locking hole are both regular hexagonal.

[0014] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0015] 1. In the process of photovoltaic panel installation, since the fixing base is set on the top of the protruding ridge, it will not cause damage to the surface of the profiled steel sheet, thus preventing rainwater leakage.

[0016] 2. In this utility model, the positioning part in the fixing seat can initially limit and fix the locking plate in the X-axis direction, which not only facilitates the installation between the first fixing screw and the second fixing screw, but also ensures that the locking plate will not be displaced in the X-axis direction after installation. At the same time, the two sets of first fixing screws and one set of second fixing screws are triangularly distributed, which can improve the locking effect of the locking plate and further improve the stability of the locking plate after locking.

[0017] 3. In this utility model, since the cross-section of the support part at the top of the fixing seat is an inverted isosceles trapezoid, the contact area between the fixing seat and the fixing frame can be effectively expanded, thereby improving the supporting effect of the fixing seat on the fixing frame and the photovoltaic panel and ensuring the stability of the photovoltaic panel after installation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 In this embodiment of the utility model, a roofing system integrating profiled steel sheet and photovoltaic module includes a steel sheet body 1 and a fixing frame 2 set on the top of the steel sheet body 1. A photovoltaic panel 3 is fixedly connected inside the fixing frame 2. A protruding rib 5 is set on the top of the steel sheet body 1, and a fixing seat 8 is set on the top of the protruding rib 5.

[0026] Locking plates 6 are provided on both sides of the fixed base 8, and the fixed frame 2 is fixedly connected to the locking plates 6.

[0027] Preferably, the fixing base 8 includes a rectangular portion 8002 and a positioning portion 8003 fixedly connected to the top of the protruding rib 5. A support portion 8001 is fixedly connected to the top of the rectangular portion 8002. The cross-section of the support portion 8001 is an inverted isosceles trapezoid. The cross-section of the support portion 8001 at the top of the fixing base 8 is an inverted isosceles trapezoid, which can effectively expand the contact area between the fixing base 8 and the fixing frame 2, improve the support effect of the fixing base 8 on the fixing frame 2 and the photovoltaic panel 3, and ensure the stability of the photovoltaic panel 3 after installation.

[0028] Preferably, the locking plate 6 includes a horizontal part 6001, an inclined part 6002, and a snap-fit ​​part 6003. The snap-fit ​​part 6003 snaps into the interior of the positioning part 8003. One side of the outer wall of the inclined part 6002 is pressed against one side of the outer wall of the support part 8001. The top of the horizontal part 6001 and the top of the support part 8001 are located on the same horizontal plane. The positioning part 8003 in the fixing seat 8 can perform preliminary X-axis direction limiting and fixing of the locking plate 6, which not only facilitates the installation work between the first fixing screw 9 and the second fixing screw 10, but also ensures that the locking plate 6 will not have X-axis direction displacement after installation.

[0029] Preferably, a first circular hole 6004 and a second circular hole 6005 are respectively opened on one side of the outer wall of the snap-fit ​​part 6003. A second fixing screw 10 and a first fixing screw 9 are respectively inserted into the first circular hole 6004 and the second circular hole 6005. Both ends of the second fixing screw 10 and the first fixing screw 9 pass through the rectangular part 8002. The two sets of locking plates 6 are fixed to both sides of the fixing base 8 by the first fixing screw 9 and the second fixing screw 10. Then, the fixing frame 2 and the locking plate 6 are fastened and fixed by the fixing bolt 4, which effectively completes the stable installation of the photovoltaic module.

[0030] Preferably, the two sets of locking plates 6 are locked to the outer walls of both sides of the fixing seat 8 by the first fixing screw 9 and the second fixing screw 10. There are two sets of first round holes 6004. The two sets of first round holes 6004 and second round holes 6005 are distributed in an isosceles triangle on one side of the outer wall of the snap-fit ​​part 6003. The two sets of first fixing screws 9 and one set of second fixing screws 10 are distributed in a triangle, which can improve the locking effect of the locking plate 6 and further improve the stability of the locking plate 6 after locking.

[0031] Preferably, the top outer wall of the locking plate 6 has a threaded hole 6006, and the top of the fixing frame 2 is provided with a fixing bolt 4. The fixing bolt 4 is threadedly connected to the threaded hole 6006, and the fixing frame 2 can be fastened to the top of the locking plate 6 by the fixing bolt 4.

[0032] Preferably, the top outer wall of the other locking plate 6 is provided with a locking hole 6007, and the bottom outer wall of the fixing frame 2 is fixedly connected with a positioning post 7. The positioning post 7 passes through the inside of the locking hole 6007. The cross-section of the positioning post 7 and the locking hole 6007 are both regular hexagonal. By locking the positioning post 7 into the locking hole 6007, the fixing frame 2 can be initially fixed. Moreover, the cross-section of the positioning post 7 is regular hexagonal, which can prevent the positioning post 7 from rotating in the locking hole 6007. At the same time, the positioning post 7 and the fixing bolt 4 are diagonally distributed, thereby improving the fixing effect of the fixing frame 2.

[0033] Working principle: When the photovoltaic module needs to be installed, the two sets of locking plates 6 can be fixed to both sides of the fixing base 8 using the first fixing screw 9 and the second fixing screw 10. Then, the fixing frame 2 and the locking plates 6 are tightened and fixed using the fixing bolts 4, which effectively completes the stable installation of the photovoltaic module. At the same time, during the installation of the photovoltaic panel 3, since the fixing base 8 is set on the top of the protruding rib 5, it will not damage the surface of the profiled steel sheet, thus preventing rainwater leakage. Furthermore, the positioning part 8003 in the fixing base 8 can perform preliminary X-axis direction limiting and fixing of the locking plates 6. This not only facilitates the installation of the first fixing screw 9 and the second fixing screw 10, but also ensures that the locking plate 6 will not shift in the X-axis direction after installation. At the same time, the two sets of first fixing screws 9 and one set of second fixing screws 10 are arranged in a triangle, which can improve the locking effect of the locking plate 6 and further improve the stability of the locking plate 6 after locking. In addition, the cross-section of the support part 8001 at the top of the fixing seat 8 is an inverted isosceles trapezoid, which can effectively expand the contact area between the fixing seat 8 and the fixing frame 2, improve the support effect of the fixing seat 8 on the fixing frame 2 and the photovoltaic panel 3, and ensure the stability of the photovoltaic panel 3 after installation.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
