[0030] Please refer to Figures 1 to 10 As shown, the present invention discloses a photovoltaic roof waterproof structure for waterproofing photovoltaic modules 100 when installed on a roof. A plurality of first intervals 101 and a plurality of second intervals 102 are provided between a plurality of photovoltaic modules 100 arranged in a matrix, and the first intervals 101 and the second intervals 102 are crisscrossed. That is, a first interval 101 is provided between two photovoltaic modules 100 adjacent to each other in the horizontal direction, and a second interval 102 is provided between two photovoltaic modules 100 adjacent to each other in the vertical direction, and the first intervals 101 and the second intervals 102 are crisscrossed. The photovoltaic roof waterproof structure of the present invention includes:

[0031] A plurality of main water tanks 1 and a plurality of auxiliary water tanks 2, wherein the main water tanks 1 extend longitudinally and the auxiliary water tanks 2 extend transversely, the auxiliary water tanks 2 are located above the main water tanks 1 and opposite ends of each auxiliary water tank 2 extend into one of the main water tanks 1, the main water tanks 1 are correspondingly arranged below the first compartment 101 and the auxiliary water tanks 2 are correspondingly arranged below the second compartment 102;

[0032] The first rubber strip 3 and the second rubber strip 4 are respectively filled in the first gap 101 and the second rubber strip 4 is respectively filled in the second gap 102 .

[0033] Compared with the prior art, the present invention completely seals the first gap 101 provided between two laterally adjacent photovoltaic modules 100 and the second gap 102 provided between two longitudinally adjacent photovoltaic modules 100 through the first rubber strip 3 and the second rubber strip 4. Such an arrangement can well achieve waterproofing of the photovoltaic roof; even in rainy weather, especially heavy rain, a small amount of water flows downward from the first gap 101 and the second gap 102, and flows into the main water tank 1 through the end of the auxiliary water tank 2, and then flows to the ground from the end of the main water tank 1. Therefore, the present invention has a good roof waterproofing effect.

[0034] Please refer to Figures 4 to 10 As shown, the cross-section of the first adhesive strip 3 is T-shaped, and the cross-section of the second adhesive strip 4 is D-shaped. In other words, the photovoltaic roof waterproofing structure of the present invention uses two different adhesive strips to fill the criss-cross first and second intervals 101, 102. This is because the first and second intervals 101, 102 are set to different widths, and the first interval 101 is usually smaller than the second interval 102.

[0035] Please refer to Figures 6 to 8 and Figure 10 As shown, the first rubber strip 3 includes a cap portion 31 and an insert portion 32. The insert portion 32 is integrally connected to the middle and lower portion of the cap portion 31, so that the cross-section of the first rubber strip 3 forms the T-shape. The T-shaped first rubber strip 3, with the cap portion 31 exposed at the top, has a larger coverage area, and is used for the larger second spacer 102, achieving a better sealing effect.

[0036] Please refer to Figure 1 、 Figure 3 、 Figures 6 to 8As shown, a central pressure block 5 is also disposed within the first compartment 101. The central pressure block 5 has a central opening 51 and an open end 52 located above the central opening 51. The insert portion 32 is configured to compress and fit the central pressure block 5 within the central opening 51, and the cap portion 31 is configured to seal the central opening 51 at the open end 52. This arrangement ensures that the central pressure block 5 securely presses and connects two adjacent photovoltaic modules 100. Furthermore, the indented structure of the insert portion 32 ensures a sealing effect.

[0037] Please refer to Figure 1 、 Figures 6 to 8 As shown, it can be imagined that the cap portion 31 is in the shape of an elongated strip when viewed from above. The cap portion 31 has an upper surface 311 facing away from the insertion portion 32, a lower surface 312 facing the insertion portion 32, and two ridges 313 connecting the upper surface 311 and the lower surface 312 on the left and right sides. The cross-section of the upper surface 311 is an arc extending from left to right along the transverse direction, and the lower surface 312 is two arcs extending from the left and right sides of the insertion portion 32, respectively. The curvature of the upper surface 311 is greater than that of the lower surface 312. This arrangement ensures that the cap portion 31 has a covering and sealing effect on the middle opening 51 at the opening end 52; the ridges 313 protrude from the upper surface 311 toward the lower surface 312. This arrangement further enhances the covering and sealing effect.

[0038] Please refer to Figure 10 As shown, the cross-section of the convex strip portion 313 is an arc having a 3 / 4 circumference, which facilitates further glue dispensing between the convex strip portion 313 and the middle pressure block 5 and further enhances the sealing effect.

[0039] Please refer to Figure 4 、 Figure 5 and Figure 9 As shown, the second rubber strip 4 includes a vertical side portion 41 and an arcuate side portion 42. The opposite ends of the arcuate side portion 42 are connected to the opposite ends of the vertical side portion 41 in a one-to-one correspondence, so that the cross-section of the second rubber strip 4 forms the D-shape. Because the lower connection between the vertical side portion 41 and the arcuate side portion 42 forms a guide angle, the second rubber strip 4 can be easily guided into the second compartment 102 when used in a smaller second compartment 102. The second rubber strip 4 is completely located within the second compartment 102, and the arcuate side portion 42 is squeezed so that the vertical side portion 41 and the arcuate side portion 42 are in contact with the walls on both sides of the second compartment 102, thereby achieving a good sealing effect.

[0040] Please continue to refer to Figure 4 、 Figure 5 and Figure 9 As shown, the vertical side portion 41 is completely fitted with the frame of one of the photovoltaic components 100 and the curved side portion 42 is at least partially fitted with the frame of the other photovoltaic component 100, the curved side portion 42 is adjacent to the frame of the other photovoltaic component 100, and the curved side portion 42 can be squeezed, specifically squeezed by the frame of the other photovoltaic component 100 toward the frame of the photovoltaic component 100 to which the vertical side portion 41 is attached, so as to seal the second gap 102.

[0041] Please refer to Figures 1 to 10 As shown, the photovoltaic roof waterproof structure of the present invention further includes a building purlin 6, a support base 7, and a support member 8. The support base 7 is located below the intermediate pressure block 5 and above the main water tank 1, and is used to support and fix the intermediate pressure block 5 to the main water tank 1. The support member 8 is located below the main water tank 1 and above the building purlin 6, and is used to fix the main water tank 1 to the building purlin 6.

[0042] Please refer to Figure 10 As shown, the photovoltaic roof waterproof structure of the present invention also includes a reinforcement member 9 and a fastener 10. The reinforcement member 9 is arranged on the bottom of the intermediate pressure block 5, and the fastener 10 passes through the reinforcement member 9 and the bottom of the intermediate pressure block 5 and is positioned on the building purlin 6.

[0043] To sum up, compared with the prior art, the present invention completely seals the first gap 101 between two laterally adjacent photovoltaic modules 100 and the second gap 102 between two longitudinally adjacent photovoltaic modules 100 through the first rubber strip 3 and the second rubber strip 4. Such a setting can well achieve waterproofing of the photovoltaic roof; even in rainy weather, especially heavy rain weather, a small amount of water flows downward from the first gap 101 and the second gap 102, and flows into the main water tank 1 through the end of the auxiliary water tank 2, and then flows to the ground from the end of the main water tank 1. The present invention has a good roof waterproofing effect.

The understanding of the present invention should be based on those skilled in the art. Although this specification describes the present invention in detail with reference to the above embodiments, those skilled in the art should understand that those skilled in the art can still modify or make equivalent substitutions to the present invention, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included within the scope of the claims of the present invention.
