DETAILED DESCRIPTION

[0032] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0033] The present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. Figures 1-5 The present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0034] The present application discloses a photovoltaic connecting assembly. Referring to Figures 1-2 , the photovoltaic connecting assembly comprises a single-fold hook 1, a three-fold hook 2 and a connecting piece 3. The single-fold hook 1 comprises a first right-angle segment 1-1 and a second right-angle segment 1-2 which are connected perpendicularly to each other. The three-fold hook 2 comprises a connecting segment 2-1, a slit segment 2-2, an extending segment 2-3 and a supporting segment 2-4 which are connected in sequence; the connecting segment 2-1 and the slit segment 2-2, the slit segment 2-2 and the extending segment 2-3, and the extending segment 2-3 and the supporting segment 2-4 form included angles respectively; and the two included angles between the connecting segment 2-1, the slit segment 2-2 and the extending segment 2-3 are alternate interior angles, and the two included angles between the slit segment 2-2, the extending segment 2-3 and the supporting segment 2-4 are same-side interior angles. The second right-angle segment 1-2 and the connecting segment 2-1 are overlapped with each other and detachably connected through the connecting piece 3, and the first right-angle segment 1-1 is used to connect with a preset base of a roof.

[0035] Under this design, the photovoltaic connecting assembly is presented as two segments of connectable connecting assemblies, and the relative arrangement angles of the single-fold hook 1 and the three-fold hook 2 can be adjusted according to requirements to form a connecting assembly in an S shape as shown in Figure 1 , or a connecting assembly in a W shape as shown in Figure 2 , so that the use form of the connecting assembly is more flexible, and multiple use forms can be provided for users. In addition, in the actual use process, the single-fold hook 1 or the three-fold hook 2 can be replaced according to requirements, so that the size adjustment of the photovoltaic connecting assembly can be realized at a lower cost to adapt to the actual gap height of the upper and lower tiles 7, and in the subsequent maintenance, the maintenance cost can be reduced by replacing only the damaged single-fold hook 1 or three-fold hook 2.

[0036] Specifically, the single-fold hook 1 is in the shape of L as a whole, which is formed by single bending of a hard plate material, and the first right-angle section 1-1 and the second right-angle section 1-2 are formed by single bending. The surface of the second right-angle section 1-2 is provided with through holes for assembling the connecting piece 3, and preferably two through holes are provided to ensure firm connection (correspondingly, the connecting section 2-1 of the three-fold hook 2 is provided with corresponding through holes). The first right-angle section 1-1 can be provided with or without through holes. For example, when the first right-angle section 1-1 is not provided with through holes, the first right-angle section 1-1 can be fixed on the roof batten 5 or other roof base by welding. When the first right-angle section 1-1 is provided with through holes, it can be anchored on the roof base by bolts.

[0037] As preferred, the length of the first right-angle section 1-1 is longer than the length of the second right-angle section 1-2. Generally, when the length of the second right-angle section 1-2 is selected, it is necessary to ensure that the single-fold hook 1 does not affect the laying of the tile surface layer and the overall drainage requirement; when the length of the first right-angle section 1-1 is selected, it is necessary to ensure that the first right-angle section 1-1 has sufficient welding surface when welded with the batten 5.

[0038] Further, the three-fold hook 2 is generally in the shape of U, which is formed by three bending of a hard plate material, and the connecting section 2-1, the penetrating section 2-2, the extending section 2-3 and the supporting section 2-4 are formed by three bending.

[0039] In some specific embodiments, the width of the port surrounded by the penetrating section 2-2, the extending section 2-3 and the supporting section 2-4 of the three-fold hook 2 (i.e. the distance between the penetrating section 2-2 and the supporting section 2-4) is greater than the thickness of the tile 7, so as to leave sufficient construction and structural support space. Preferably, the width is 100 mm.

[0040] As preferred, the three-fold hook 2 is an integrated aluminum alloy hook piece with three bending angles. The material process of the integrated aluminum alloy hook piece is preferably aluminum alloy + anodic oxidation process; the three-fold hook 2 under this process has low density and light weight, reduces the burden on the roof structure, and has good corrosion resistance after anodic oxidation process.

[0041] In some specific embodiments, the material is preferably 6061 aluminum alloy, so that the three-fold hook 2 has excellent processing performance and good corrosion resistance, and ensures that the three-fold hook 2 has good strength and hardness to meet the requirements of the use environment.

[0042] Further, in the embodiment, the end face of the support section 2-4 is provided with a through hole 2-5 in the thickness direction, which is located at the center of the end face of the support section 2-4 and away from the side of the included angle formed by the support section 2-4 and the extension section 2-3; that is, the through hole 2-5 deviates from the center of the end face and is away from the included angle formed by the support section 2-4 and the extension section 2-3.

[0043] Further, in the embodiment, the connecting member 3 includes a bolt and a nut. The connecting section 2-1 and the second right-angle section 1-2 are overlapped with each other and fixed by the nut after being penetrated by the bolt. The bolt connection form is faster in installation speed on site, greatly accelerates the construction progress and reduces the labor cost. At the same time, the bolt connection does not change the physical properties of the component, ensuring the structural integrity; in the aspect of later maintenance, the bolt connection is also easy to disassemble and replace.

[0044] Under the design, the actual assembly situation of the single-fold hook 1 and the three-fold hook 2 can be determined based on the selection of the overlapping surface of the connecting section 2-1 and the second right-angle section 1-2, for example, adjusted to the overlapping surface form as shown in the figure, at this time, the single-fold hook 1 and the three-fold hook 2 jointly form an S-shaped connecting assembly; when the single-fold hook 1 is turned over, the inner side included angle of the single-fold hook 1 and the included angle formed between the connecting section 2-1 and the slit section 2-2 become an internal alternate angle, the single-fold hook 1 and the three-fold hook 2 will form a W-shaped connecting assembly as shown in the figure, so as to meet the various use requirements of users. In other embodiments, the connecting member 3 can also be selected from screws, latches, locks and the like. Figure 1 Figure 2

[0045] Further, in the three-fold hook 2, the two ends of the slit section 2-2 in the thickness direction are fixed with sealing strips 4, and the sealing strips 4 are preferably flexible sealing strips. Further, the sealing strips 4 are spaced apart along the length direction of the slit section 2-2. When the slit section 2-2 is installed at the tile joint, the sealing strips 4 abut against the tiles 7. Of course, in some embodiments, when the gap is small or there is no sealing and damping requirement, the sealing strips 4 can also not be arranged at the slit section 2-2.

[0046] When the photovoltaic connecting assembly is composed of an S-shaped structure, since the support section 2-4 with the through hole 2-5 will serve as the installation basis of the photovoltaic panel 8, when the photovoltaic panel 8 or the intermediate connecting member is assembled at the through hole, the stress point of the support section 2-4 and the span of the first right-angle section 1-1 are small, the force conducted by the support section 2-4 to the first right-angle section 1-1 is not easy to cause excessive pulling of the first right-angle section 1-1, so that the first right-angle section 1-1 is relatively stable and basically will not be torn from the roof connecting basis.

[0047] ​​When the bottom installation foundation of the photovoltaic connection assembly has been determined, in order to obtain a wider installation span, the user can also use the photovoltaic connection assembly in a W-shaped structure; for example, when two rows of W-shaped photovoltaic connection assemblies are used to support photovoltaic panels, the ports of the two rows of photovoltaic connection assemblies (i.e., the ports surrounded by the through-slit section 2-2, the extension section 2-3 and the support section 2-4) are arranged facing each other, so that the support width is greatly widened.

[0048] The present application also discloses a photovoltaic roof structure with a tile roof, referring to Figures 3-5 The photovoltaic roof structure of the tile roof includes a plurality of water-following strips 5, a plurality of tile hanging strips 6, a plurality of tiles 7, a plurality of photovoltaic panels 8 and a plurality of any of the above-mentioned photovoltaic connection components. Among them, the water-following strips 5 are fixed on the surface of the roof 10, and preferably a plurality of them are fixed; a plurality of tile hanging strips 6 are fixed on the surface of the water-following strips 5, and preferably spaced apart along the slope direction of the roof 10. The tiles 7 are laid on the roof 10 and in the slope direction (i.e. Figure 5 In the direction indicated by the middle arrow a), one end of the tile 7 overlaps the tile hanging strip 6, and the other end overlaps the adjacent tile 7 below. In the horizontal arrangement, two adjacent tiles overlap each other to prevent leakage. The first right-angle segment 1-1 of the single-fold hook 1 is fixed to the water-following strip 5. The single-fold hook 1 is located below the tile 7. The through-slit segment 2-2 of the three-fold hook 2 passes through the gap between adjacent tiles 7 along the slope direction. The support segment 2-4 of the three-fold hook 2 is located above the tile 7. Multiple photovoltaic panels 8 are laid on the roof 10, and the bottom of the photovoltaic panels 8 is connected to the corresponding support segment 2-4.

[0049] Further preferably, Figure 4 As shown, in some embodiments, the tiles 7 are curved, and the penetration section 2-2 of the tri-fold hook 2 is positioned at the crest of the tile 7. This design can, to a certain extent, mitigate the impact of the tri-fold hook 2 on tile laying, ensuring waterproofing and enhancing the safety of the roof tiles. Furthermore, since this solution does not damage the tile structure, construction efficiency is high. Compared to methods that damage the tile surface and then repair it, labor hours can be reduced by approximately 50%, facilitating and expediting construction.

[0050] Furthermore, in some embodiments, Figure 4 As shown, the selected tile 7 has an upper supporting groove 7-1 at the upper edge of one end, and a lower supporting groove 7-2 is opened at the lower part of the opposite end. The through-slit section 2-2 is penetrated between the upper supporting groove 7-1 and the lower supporting groove 7-2, and the sealing strip 4 at the upper end of the through-slit section 2-2 contacts the lower supporting groove 7-2 of the upper tile 7, and the sealing strip 4 at the lower end of the through-slit section 2-2 contacts the upper supporting groove 7-1 of the lower tile 7.

[0051] Further, the roof structure further comprises a guide rail 9, the support section 2-4 in the three-fold hook 2 is fixed with the guide rail 9 through bolt-nut or other fasteners, the guide rail 9 is transversely arranged and the top of the guide rail 9 is fixed with the photovoltaic panel 8.
