[0031] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0032] Please see Figure 1-4As shown in this embodiment: a water-resistant photovoltaic roof tile includes several horizontal beams 1, male photovoltaic tiles 2, and female photovoltaic tiles 3. The male photovoltaic tiles 2 and female photovoltaic tiles 3 are mounted on the horizontal beams 1. Multiple sets of male photovoltaic tiles 2 are arranged in a matrix, and the male photovoltaic tiles 2 in the same row are arranged in a stepped manner. The male photovoltaic tile 2 includes a first connecting frame 2.1. The first connecting frame 2.1 is provided with several photovoltaic panels 2.6 arranged in a matrix. The first connecting frame 2.1 is spliced ​​with the first connecting frame 2.1 of the adjacent male photovoltaic tile 2. The first connecting frame 2.1 extends outward from the right side with a first drainage part 2.2. A second drainage section 2.3 is provided on the left side of the frame 2.1. The first drainage section 2.2 is provided with a first drainage groove 2.2.1 and a lower drainage plate 2.2.2 from the inside to the outside. The second drainage section 2.3 is provided with a second drainage groove 2.3.1 and an upper drainage plate 2.3.2 from the inside to the outside. A drainage channel 2.4 is left between the upper drainage plate 2.3.2 and the outer wall of the first drainage groove 2.2.1. The upper drainage plate 2.3.2 and the lower drainage plate 2.2.2 are snapped together to form a drainage cavity 2.5. The accumulated water enters the drainage cavity 2.5 through the drainage channel 2.4. The accumulated water in the drainage channel 2.4 flows out under the influence of gravity to achieve drainage.

[0033] The photovoltaic tiles 2 in the same row are arranged in a stepped pattern, forming a natural drainage slope. The upper drainage plate 2.3.2 and the lower drainage plate 2.2.2 are nested to form a drainage cavity 2.5. Accumulated water, under the influence of gravity, enters the drainage cavity 2.5 through the drainage channel 2.4 and flows out. Simultaneously, in conjunction with the first drainage groove 2.2.1 and the second drainage groove 2.3.1, a multi-layered drainage channel is formed, avoiding the problem of water accumulation and frame corrosion in traditional planar layouts, thus extending service life. In some embodiments, such as... Figures 9-11 As shown, the male photovoltaic tile 2 and the female photovoltaic tile 3 are spliced ​​together, and the splicing surface is flush with the roof plane. It should be noted that the photovoltaic panel 2.6 is embedded in the connecting frame, forming a flush roof surface with the drainage part, which completely eliminates the light reflection pollution caused by the outward protrusion of the photovoltaic panel 2.6 and reduces the risk of wind resistance.

[0034] In some embodiments, such as Figure 4 As shown, the first drainage channel 2.2.1 includes first ear plates 2.2.3 arranged opposite each other. The first ear plates 2.2.3 extend inward to the first water-lubricating plates 2.2.4. A gap is left between the two first water-lubricating plates 2.2.4 to allow water to enter. It should be noted that the arrangement of the first water-lubricating plates 2.2.4 allows the water to flow from the upper layer to the lower layer. The water first drains through the upper surface of the first water-lubricating plates 2.2.4. When the drainage pressure is too high, the water flows into the first drainage channel 2.2.1 through the gap between the first water-lubricating plates 2.2.4, sharing the drainage pressure and performing stratified drainage.

[0035] In some embodiments, such as Figure 4As shown, the second drainage channel 2.3.1 includes two opposing second ear plates 2.3.3. The second ear plates 2.3.3 extend inward to a second water-lubricating plate 2.3.4. A gap is left between the two second water-lubricating plates 2.3.4 to allow water to enter. It should be noted that the arrangement of the second water-lubricating plates 2.3.4 allows the water to flow from the upper layer to the lower layer. The water first drains through the upper surface of the second water-lubricating plate 2.3.4. When the drainage pressure is too high, the water flows into the second drainage channel 2.3.1 through the gap between the second water-lubricating plates 2.3.4, sharing the drainage pressure and performing stratified drainage.

[0036] In some embodiments, such as Figures 4-8 As shown, the upper end face of the hydrophobic cavity 2.5 is provided with several upper partition strips 2.5.1, and the lower end face of the hydrophobic cavity 2.5 is provided with several lower partition strips 2.5.2. The upper partition strips 2.5.1 and lower partition strips 2.5.2 are staggered along the width direction of the hydrophobic cavity 2.5, dividing the hydrophobic cavity 2.5 into adjacent and sequentially connected unit hydrophobic grids. It should be noted that the male photovoltaic tile 2 and the female photovoltaic tile 3 are connected by the hydrophobic upper plate 2.3.2 and the hydrophobic lower plate 2.2.2 to form the hydrophobic cavity 2.5. The staggered upper partition strips 2.5.1 and lower partition strips 2.5.2 in the cavity divide the water flow pressure.

[0037] In some embodiments, such as Figures 9-11 As shown, the male photovoltaic tile 2 includes a second connecting frame 2.7 spliced ​​with the adjacent female photovoltaic tile 3. The second connecting frame 2.7 includes a connecting upper plate 2.7.1. The female photovoltaic tile 3 is provided with a connecting lower plate 3.1 spliced ​​with the connecting upper plate 2.7.1. The lower end face of the connecting upper plate 2.7.1 is provided with a plurality of first water-blocking strips 2.7.2. The plurality of first water-blocking strips 2.7.2 are spaced apart along the width direction of the connecting upper plate 2.7.1, and the first water-blocking strips 2.7.2 end The end abuts against the end face of the connecting lower plate 3.1. The upper end face of the connecting lower plate 3.1 is provided with several second water-blocking strips 3.2. The second water-blocking strips 3.2 abut against the end face of the connecting upper plate 2.7.1. The first water-blocking strips 2.7.2 and the second water-blocking strips 3.2 are staggered. It should be noted that at the splicing point of the male photovoltaic tile 2 and the female photovoltaic tile 3, the first water-blocking strip and the second water-blocking strip 3.2 are staggered to form a maze-like barrier, which double blocks the rainwater penetration path and improves the overall waterproof reliability.

[0038] It should be noted that the second connecting frame 2.7 differs from the first connecting frame 2.1 only at the splicing point with the parent photovoltaic tile 3.

[0039] In some embodiments, such as Figure 2As shown, the upper side frame of the first connecting frame 2.1 and the second connecting frame 2.7 are provided with several first fixing holes 2.8. The first connecting frame 2.1 and the second connecting frame 2.7 are both erected between the adjacent crossbeam 1 supports. The first connecting frame 2.1 and the second connecting frame 2.7 are fixed to the crossbeam 1 through the first fixing holes 2.8 and fixing bolts. At the same time, the upper row of the same frame covers the top of the first fixing holes 2.8. It should be noted that fixing the male photovoltaic tile 2 to the crossbeam 1 with bolts forms a rigid support structure, which disperses the impact of external forces such as wind pressure and snow load on the photovoltaic tile and significantly improves the system's wind resistance. At the same time, the design of the upper row of frames covering the fixing holes forms a physical shield, preventing rainwater from directly contacting the bolt connection and effectively preventing rainwater from seeping into the gaps of the first fixing holes 2.8. Each pair of crossbeams 1 fixes one photovoltaic tile, making the connection tighter and the support stronger.

[0040] In some embodiments, such as Figure 2 As shown, several second fixing holes 3.3 are provided on the upper edge of the frame of the female photovoltaic tile 3. A single female photovoltaic tile 3 is mounted between adjacent crossbeams 1, and the female photovoltaic tile 3 is fixed to the crossbeam 1 through the second fixing holes 3.3 and fixing bolts. At the same time, the upper row of the same frame covers the top of the second fixing holes 3.3. It should be noted that the male photovoltaic tile 2 is fixed to the crossbeam 1 by bolts to form a rigid support structure. At the same time, the design of the upper row of frames covering the second fixing holes 3.3 forms a physical shield, blocking rainwater from directly contacting the bolt connection. This can effectively prevent rainwater from seeping into the gaps of the fixing holes. One female photovoltaic tile 3 is fixed for every two crossbeams 1, making the connection tighter and the support stronger.

[0041] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
