[0037] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a metal roof photovoltaic device provided in an embodiment of the present application. Figure 2 A front view of a metal roof photovoltaic device provided in an embodiment of the present application.

[0038] In the first specific implementation manner, the metal roof photovoltaic device provided by the embodiment scheme of the present application mainly includes a metal roof 1 and a photovoltaic module 2, the metal roof 1 has a roof panel crest 12 and a roof panel lock edge 11, the metal roof photovoltaic device also includes a quick-release clamp 3 and a bearing base 4, the quick-release clamp 3 is installed on the roof panel crest 12, and the quick-release clamp 3 is used to achieve a snap-on connection with the photovoltaic module 2; the bearing base 4 is installed on the roof panel lock edge 11, and the bearing base 4 is used to achieve bearing of the photovoltaic module 2 when the photovoltaic module 2 is installed on the quick-release clamp 3.

[0039] In the architecture description of the metal roof photovoltaic device, first, the work before the installation of the photovoltaic module 2 is carried out: the quick-installation clamp 3 and the bearing base 4 are installed on the metal roof 1; then, the installation work of the photovoltaic module 2 is carried out: the photovoltaic module 2 is installed on the quick-installation clamp 3 and the bearing base 4.

[0050] When the top of the roof panel crest 12 is clamped in place, the first elastic arm 311 is pressed downwardly to the top of the roof panel crest 12, thereby preventing the top of the roof panel crest 12 from being deformed.

[0051] Please continue to refer to Figure 5 In some embodiments, the second clamp body 32 includes a pair of second elastic arms 321, the spacing between the pair of second elastic arms 321 changes with the bending angle of the second elastic arms 321, the back rail member 22 has a downwardly opening arched groove 221, the side walls of the arched groove 221 are inclined, and the arched groove 221 is used for the structure of the photovoltaic component 2 and the quick-release clamp 3 to be inserted.

[0053] In this embodiment, the connecting line of a pair of first elastic arms 311 and the connecting line of a pair of second elastic arms 321 can be perpendicular to each other. Therefore, the fixing direction of the first elastic arm 311 and the metal roof 1 and the fixing direction of the second elastic arm 321 and the photovoltaic module 2 are perpendicular to each other. Therefore, the fixing direction of the metal roof 1 and the quick-release clamp 3 and the fixing direction of the photovoltaic module 2 and the quick-release clamp 3 are perpendicular to each other. For example, the fixing direction of the metal roof 1 and the quick-release clamp 3 is horizontal, and the fixing direction of the photovoltaic module 2 and the quick-release clamp 3 is vertical. With this arrangement, the fixing directions of the metal roof 1, the photovoltaic module 2 and the quick-release clamp 3 are crossed and perpendicular, thereby improving the overall installation stability of the metal roof photovoltaic device.

[0054] Please refer to Figure 6 , Figure 6 A schematic diagram of the structure of the support base provided in an embodiment of the present application.

[0055] In some embodiments, the supporting base 4 includes a supporting body 41 and a base body 42 which are connected to each other. The base body 42 is located at the lower side of the supporting body 41 .

[0056] In this embodiment, the base body 42 is installed on the roof panel lock edge 11 and fixed with glue.

After the bearing base 4 is installed, the photovoltaic module 2 is carried upward by the bearing base 4, and the upper surface of the base body 42 is designed to be in a flat form that fits the bottom of the photovoltaic module 2.

[0057] Please refer to Figure 7 , Figure 7 A side view of a metal roof photovoltaic device provided in an embodiment of the present application.

[0058] In some embodiments, the photovoltaic module 2 includes a laminate 21 and a back rail 22 , wherein the back rail 22 is located at the back of the laminate 21 .

[0059] In this embodiment, the back rail 22 is snap-connected with the quick-installation clamp 3, and the laminate 21 is supported by the supporting base 4 when the back rail 22 is installed on the quick-installation clamp 3. During installation, after the quick-installation clamp 3 is installed, the photovoltaic module 2 is installed on the upper side of the quick-installation clamp 3, the back rail 22 is aligned above the quick-installation clamp 3, and the photovoltaic module 2 is pressed downward on the quick-installation clamp 3.

[0060] Please continue to refer to Figure 7 In some embodiments, the quick-release clamp 3 includes a second clamp body 32 for realizing a snap connection with the back rail member 22, the second clamp body 32 includes a pair of second elastic arms 321, the spacing between the pair of second elastic arms 321 changes with the bending angle of the second elastic arms 321, the back rail member 22 has a downwardly opening arched groove 221, the side wall of the arched groove 221 is inclined, and the arched groove 221 is used for a pair of second elastic arms 321 to be snapped in.

[0061] The second elastic arms 321 are pressed downwardly to the top of the bracket 320 so as to prevent the bracket 320 from being deformed.

[0062] Please continue to refer to Figure 7 In some embodiments, the photovoltaic assembly 2 further includes a liner member 23 , and the liner member 23 is located at the back of the laminate 21 .

[0063] In this embodiment, the lining tube member 23 and the back rail member 22 are both arranged in the transverse direction. Since the lining tube member 23 is not through-length, the lining tube member 23 is separated at the roof panel lock edge 11, so that each lining tube member 23 spans the adjacent roof panel lock edge 11. In addition, the number of lining tube members 23 and back rail members 22 in the photovoltaic module 2 is multiple, and the lining tube members 23 and the back rail members 22 are cross-distributed in the longitudinal direction.

The roof panel crest 12 and the roof panel lock edge 11 are cross-distributed in the transverse direction.

[0067] Please continue to refer to Figure 1It can be seen that the photovoltaic module 2 is in the shape of a plate, and the length direction of the photovoltaic module 2 is defined as the horizontal direction, and the width direction of the photovoltaic module 2 is the vertical direction. Therefore, the single-piece roof panel locking edge 11 and the single-piece roof panel crest 12 are both extended in the longitudinal direction, and the multiple roof panel crests 12 and the roof panel locking edge 11 are cross-distributed in the horizontal direction. Multiple bearing bases 4 are distributed at intervals on the single-piece roof panel locking edge 11, and multiple quick-install clamps 3 are distributed at intervals on the single-piece roof panel crest 12.
