Description

Technical Field

[0001] This utility model relates to a photovoltaic roof and belongs to the field of photovoltaic technology. Background Technology

[0002] The corrugated cross-section of trapezoidal corrugated steel sheets is trapezoidal, making it impossible to clamp the corrugations or other shaped features on the surface of the sheet using a clamp. Related technologies use an integrated clamp consisting of two clamping arms, which are glued to the corrugated steel sheet, eliminating the need for drilling holes in the sheet. However, the fixed positions of the two clamping arms prevent the clamp and the sheet from fully engaging, affecting the fixing effect. Utility Model Content

[0025] Please refer to Figures 1 to 7 As shown, this utility model discloses a photovoltaic roof, including a corrugated steel sheet 1, a guide rail 2, a clamp 3, and a photovoltaic module 4. One end of the clamp 3 is connected to the guide rail 2, and the other end of the clamp 3 is connected to the corrugated steel sheet 1. The photovoltaic module 4 is connected to the guide rail 2 through a pressure block 5.

[0026] Color steel sheet 1 is a trapezoidal color steel sheet. Please refer to this. Figure 1 As shown, the corrugated steel sheet 1 includes corrugated peaks 11, which are trapezoidal in shape. Please refer to... Figure 2 As shown, the wave crest 11 includes a top wall portion 111 and two side wall portions 112 connected to both sides of the top wall portion 111. The two side wall portions 112 are respectively arranged at an obtuse angle to the top wall portion 111.

[0027] Please refer to Figure 6 As shown, the guide rail 2 includes a guide rail body 21 and segmented connecting plates 22. The top of the guide rail body 21 has a top mounting groove 211, the bottom of the guide rail body 21 has a bottom mounting groove 212, and the sides of the guide rail body 21 have side embedding grooves 213. Segmented connecting plates 22 are embedded in the side embedding grooves 213 at the connection points of two adjacent guide rail bodies 21. Fastening bolts 23 pass through the segmented connecting plates 22 and the side embedding grooves 213 from the outside in, fixing the two guide rail bodies 21 together. Please refer to... Figure 7 As shown, the segmented connecting plate 22 is engaged with the guide rail body 21 through the slot 221, which is a positioning slot and serves a positioning function.

[0028] Please refer to Figure 2 As shown, the clamp 3 includes a base 31 and two clamping plates 32 movably connected to the base 31. The base 31 rests between the corrugated steel sheet 1 and the guide rail 2 and is bolted to the guide rail 2. Grooves are provided on both sides of the base 31. Each clamping plate 32 includes a support portion 321 and a clamping portion 322 connected to the support portion 321. The clamping portion 322 is bent relative to the support portion 321. A movable shaft 323 is provided at the end of the support portion 321 away from the clamping portion 322. The two movable shafts 323 are correspondingly located in the two grooves and can rotate within the grooves, enabling the clamping plate 32 to be properly assembled with the corrugated steel sheet 1, thus ensuring a stable connection between the clamp 3 and the corrugated steel sheet 1. Specifically, the clamping portion 322 is glued to the side wall portion 112 of the corrugated steel sheet 1, eliminating the need for drilling holes in the corrugated steel sheet 1 and not affecting the roof's sealing performance. The support part 321 and the base 31 are connected by tape, for example, by binding the support part 321 and the base 31 together with tape to secure them. Please refer to [reference needed]. Figure 3 As shown, the base 31 includes a base plate 311, a first side plate 312 perpendicularly connected to one side of the base plate 311, and a second side plate 313 perpendicularly connected to the other side of the base plate 311. The groove includes a first groove 3101 and a second groove 3102. The first side plate 312 includes a first groove portion 3121 protruding towards the second side plate 313, and the second side plate 313 includes a second groove portion 3131 protruding towards the first side plate 312. The first groove portion 3121 forms the first groove 3101, and the second groove portion 3131 forms the second groove 3102. The first groove portion 3121 makes the first side plate 312 a bent structure with supporting elasticity, and the second groove portion 3131 makes the second side plate 313 a bent structure with supporting elasticity.

[0029] The base plate 311 is connected to the top wall 111 by adhesive, thereby achieving a stable connection between the base 31 and the color steel tile 1.

[0030] The groove surfaces of both the first groove 3101 and the second groove 3102 are arc-shaped. Figure 2 From the main viewing angle of the middle clamp 3, the arc of the curved surface falls on a circle. The outer peripheral surface of the movable shaft 323 is adapted to the curved surface, allowing the movable shaft 323 to rotate flexibly within the groove.

[0031] Please refer to Figure 3 As shown, the movable shaft 323 and the support part 321 are connected by a connecting part 324. The thickness of the connecting part 324 is reduced relative to the movable shaft 323 and the support part 321, which is beneficial to expanding the adjustment angle of the movable shaft 323.

[0032] In the embodiment illustrated in this utility model, the first groove 3121 is located in the middle of the first side plate 312, and the second groove 3131 is also located in the middle of the first side plate 312. This arrangement raises the connection point between the base 31 and the clamping plate 32, and correspondingly, the support portion 321 is extended. The support portion 321 and the base 31 together support the photovoltaic module 4, improving the support strength of the clamp 3 and making the entire photovoltaic roof structure more stable. Please refer to... Figure 3 As shown, the base 31 includes a top plate 314, which is vertically connected to the first side plate 312 and the second side plate 313. The top plate 314 is parallel to the bottom plate 311. The top plate 314, the first side plate 312, the second side plate 313 and the bottom plate 311 together form a closed structure with a cavity, which provides high support strength.

[0033] Please refer to Figure 3 As shown, the top plate 314 includes a first extension 3141 extending beyond the first side plate 312 and a second extension 3142 extending beyond the second side plate 313. The length of the second extension 3142 is greater than the length of the first extension 3141. By providing the first extension 3141, the support strength of the clamp 3 is improved. The second extension 3142 is connected to the guide rail 2 by bolts.

[0034] Please refer to Figure 3 As shown, both the first extension 3141 and the second extension 3142 are provided with anti-slip protrusions 3140 to increase the friction between the clamp 3 and the guide rail 2. In some embodiments, the entire top plate 314 is provided with anti-slip protrusions 3140.

[0035] Please refer to Figure 2 As shown, along the length direction L of the guide rail 2, there is a gap 300 between the support part 321 and the base 31. By forming a gap 300, the clamping part 322 can be rotated inward (counterclockwise) by a certain angle as needed.

[0036] Please refer to Figure 4 As shown, in another embodiment, the clamping part 322 has an adhesive injection groove 3220 on its surface facing the corrugated steel sheet 1. During installation, adhesive is injected into the adhesive injection groove 3220 to bond and fix the clamping part 322 to the corrugated steel sheet 1, the guide rail 2 is installed on the clamp 3, and the photovoltaic module 4 is pressed against the guide rail 2 by the pressure block 5. This fixing method does not damage the original roof and avoids roof leakage.
