DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0029] Example 1

[0030] Refer to Figures 1-6 As shown, a photovoltaic structure for roof waterproofing of the present utility model includes:

[0031] Hook 2, which includes a first connecting portion 21, a waterproof portion 22, and a second connecting portion 23 connected in sequence. The first connecting portion 21 is disposed on the slope 1 to be installed, and a waterproof material is provided between the waterproof portion 22 and the tile on the slope 1.

[0032] Photovoltaic module, which includes a plurality of photovoltaic panels 6. The photovoltaic panels 6 are connected to the second connecting portion 23, and there is a spacing space between adjacent photovoltaics.

[0033] Water tank plate 5, which is disposed between the photovoltaic panel 6 and the slope 1 to be installed, and is provided with a water tank. The water tank is located below the spacing space.

[0034] For the photovoltaic structure for roof waterproofing of the present utility model, the photovoltaic structure is supported above the slope 1 through the hook 2. The first connecting portion 21 is installed on the cement beam on the roof body or fixed on the cast-in-place roof. The waterproof portion 22 extends out from the tile joint of the slope 1, and the photovoltaic module is supported through the second connecting portion 23. The photovoltaic module is a matrix of photovoltaic panels 6 arranged on the roof. The photovoltaic panels 6 are electrically connected to each other. The photovoltaic panels 6 are supported through the second connecting portion 23. Rainwater is collected below the gap between the photovoltaic panels 6 through the water tank plate 5, and the rainwater is diverted. The support by the hook 2 avoids damaging the tiles on the slope 1 and the waterproof performance of the tile surface, and improves the stability of the photovoltaic module on the roof. There is no need for the tile structure to support the photovoltaic module, and it cooperates with the water tank plate 5 to reduce the rain area and water flow on the roof, and reduce the roof waterproof pressure.

[0035] Refer to Figures 1-2 As shown, a first support assembly is provided between the hook 2 and the water tank plate 5 to support the water tank plate 5 above the ground, and the support installation points can be rearranged on the first support assembly.

[0036] The first support assembly includes: a diagonal beam 3 connected to the second connecting portion 23, and a purlin 4 connected to the diagonal beam 3. The diagonal beam 3 is arranged along the inclined direction of the slope 1, and the purlin 4 is arranged along the axial direction of the slope 1. Fewer hook 2 points are set on the roof to reduce the damage to the roof, and more hook 2 points are set on the diagonal beam 3 or the purlin 4, which can meet the installation requirements of multiple water tank plates 5 and photovoltaic modules. The diagonal beam 3 and the purlin 4 are perpendicular to each other to form a grid framework, which is adapted to the installation of the photovoltaic panel 6.

[0037] Refer to Figures 4-5As shown, the photovoltaic module and the purlin 4 are connected by a second support assembly. The second support assembly includes: a cross arm 13 connected to the purlin 4, a pressing plate 7 disposed on the cross arm 13, and a mounting groove 12 formed in the pressing plate 7. The pressing plate 7 is arranged along the spacing space direction. The peripheral side of the photovoltaic panel 6 is received in the mounting groove 12. The water trough plate 5 is locked by the cross arm 13. The water trough plate 5 is an M-shaped water trough. The cross arm 13 provides support for the pressing plate 7. The pressing plate 7 is inserted into the photovoltaic panel 6 through the mounting groove 12 to form a stepped sealing structure.

[0038] Continue to refer to Figures 4-5 As shown, the pressing plate 7 is located above the water trough. The water trough is used to collect and divert rainwater, while the pressing plate 7 is used to fix and support the photovoltaic panel 6. Setting the pressing plate 7 above the water trough can, on the one hand, facilitate the installation of the pressing plate 7, and on the other hand, it can ensure that the rainwater will not be blocked by the pressing plate 7 during the process of flowing into the water trough, thus ensuring the smooth collection and discharge of rainwater.

[0039] The water trough plate 5 is provided with limiting portions 15 on both sides of the water trough. The cross arm 13 abuts against the limiting portions 15. The limiting portions 15 provide support and fixing points for the water trough plate 5. The abutment of the cross arm 13 and the limiting portions 15 enables the water trough plate 5 to be connected to the purlin 4 or the inclined beam 3 through the cross arm 13.

[0040] Refer to Figures 2-3 As shown, the waterproof portion 22 is penetrated between the upper tile 14 and the lower tile 11 of the to-be-installed slope surface 1. The waterproof material includes a first waterproof layer 9 and a second waterproof layer 10. A first waterproof layer 9 is arranged between the waterproof portion 22 and the lower tile 11. The upper tile 14 is provided with a second waterproof layer 10. The rainwater is prevented from seeping in from the tile joints through the waterproof layer. A first waterproof layer 9 is arranged between the waterproof portion 22 and the lower tile 11, further enhancing the waterproof effect. The material of the first waterproof layer 9 usually has good waterproof performance, such as waterproof coiled materials, waterproof coatings, etc., and can effectively block the penetration of rainwater. At the same time, a second waterproof layer 10 is arranged on the upper tile 14 to provide double waterproof protection for the tile surface. The material and construction requirements of the second waterproof layer 10 are similar to those of the first waterproof layer 9. Even if part of the rainwater seeps in through the gaps of the upper tile 14, the waterproof portion 22 is penetrated between the upper tile 14 and the lower tile 11, which can prevent the rainwater from continuing to penetrate downward. At the same time, the first waterproof layer 9 between the waterproof portion 22 and the lower tile 11 provides a second waterproof structure for preventing rainwater penetration.

[0041] Continue to refer to Figures 2-3As shown, the end of the first waterproof layer 9 extends to the first connecting part 21, and the end of the second waterproof layer 10 extends to the second connecting part 23. Both the first connecting part 21 and the second connecting part 23 include a vertical part and a horizontal part opposite to the slope surface 1. The horizontal part of the first connecting part 21 is connected to the cement beam on the roof body or fixed on the cast-in-place roof, and the vertical part is adapted to the thickness of the lower layer of tiles 11 and the first waterproof layer 9. The horizontal part of the second connecting part 23 is connected to the inclined beam 3, and the vertical part of the second connecting part 23 spaces the inclined beam 3.

[0042] The first connecting part 21 is connected to the to-be-installed slope surface 1 through a fastener 8. Corresponding locking holes are provided on both the first connecting part 21 and the to-be-installed slope surface 1. The locking holes and the bottom surface of the lower layer of tiles 11 are filled with sealant. The fastener 8 is a bolt. Neutral silicone weatherproof sealant is injected into the locking holes and around the base to form a third waterproof structure.
