By adding the second filling groove 32, the use thickness of the second sealing adhesive 31 can be effectively increased, thereby increasing the bonding strength between the flexible photovoltaic panel 2 and the reinforcing rib 3, and further strengthening the supporting effect on the flexible photovoltaic panel 2, which can more effectively avoid the problem of hidden cracks caused by the gradual deformation and bending of the flexible photovoltaic panel 2 after the flexible photovoltaic assembly of this embodiment has been working outdoors for a long time, and can further improve the wind load resistance of the flexible photovoltaic assembly of this embodiment.

[0059] Specifically, the first sealing adhesive 12 and the second sealing adhesive 31 are both configured as silicone sealing adhesive.

[0060] like Figure 4 , Figure 7 and Fig. 9As shown, optionally, the mounting frame 1 includes two first connecting parts 17 and two second connecting parts 18 which can be separably arranged, the two first connecting parts 17 are arranged opposite to each other along the first horizontal direction, the two second connecting parts 18 are arranged opposite to each other along the second horizontal direction, the two second connecting parts 18 and the two first connecting parts 17 surround the step hole 11; the first connecting part 17 and the adjacent second connecting parts 18 are connected into one by an L-shaped angle code, and the first connecting part 17 is respectively provided with a first cavity 171 at both ends along the second horizontal direction, and the first cavity 171 is used for the first horizontal part of the L-shaped angle code to be movably inserted and locked by a second bolt assembly; the second connecting part 18 is respectively provided with a second cavity 181 at both ends along the first horizontal direction, and the second cavity 181 is used for the second horizontal part of the L-shaped angle code to be movably inserted and locked by a third bolt assembly. Compared with the prior art in which the mounting frame 1 is formed as one piece, the present embodiment splits the mounting frame 1 into two first connection parts 17 and two second connection parts 18, and the adjacent first connection parts 17 and second connection parts 18 are connected as one piece by an L-shaped angle code, so that the first connection parts 17 and the second connection parts 18 can be prefabricated in a processing plant, and then assembled to form the mounting frame 1, and the manufacturing process is simple and the processing cost is low; at the same time, compared with connecting the first connection part 17 and the second connection part 18 by welding, the present embodiment uses the second bolt assembly and the third bolt assembly to detachably connect the first horizontal part and the second horizontal part of the L-shaped angle code to the first connection part 17 and the second connection part 18 respectively, and each connection is fixed by bolts, so that ordinary people can complete the installation and use with the help of common tools such as wrenches, thereby reducing the difficulty of assembly.

When the reinforcing rib 3 needs to be connected to the mounting frame 1, it is only necessary to align the screw hole 33 of the reinforcing rib 3 with the first through hole 141, and then the fastening screw 34 is screwed to the screw hole 33 through the first through hole 141 to complete the assembly; when the reinforcing rib 3 needs to be removed from the mounting frame 1, it is only necessary to screw the fastening screw 34 out of the screw hole 33, and the whole disassembly process is simple to operate.
