The first connecting section 5112 is located in the first adhesive film layer 40, so that the first fixing section 5111 can be connected to the first adhesive film layer 40 through the first connecting section 5112.

[0052] It should be noted that if Figures 4 to 6 As shown, when installing the first rotating cylinder 634, the second rotating cylinder 635 and the third rotating cylinder 636, the third rotating cylinder 636 needs to be placed in the avoidance space 11122 first, and then the third rotating cylinder 636 is pushed into the installation space 11121, and then the second rotating cylinder 635 and the first rotating cylinder 634 are installed in the installation cylinder 1112 using the same steps as the third rotating cylinder 636, and then the first locking column 631 is fixed to the first rotating cylinder 634, the second locking column 632 is fixed to the second rotating cylinder 635, and the third locking column 633 is fixed to the third rotating cylinder 636 respectively. When the first rotating cylinder 634 tightens the first traction line 611, the second rotating cylinder 635 tightens the second traction line 621, and the third rotating cylinder 636 tightens the third traction line, and the angle between the first connecting section 5112 and the second connecting section 5113 meets the preset angle, the first fixed column 637 abuts against the outer surface of the second rotating cylinder 635, the second fixed column 638 abuts against the outer surface of the third rotating cylinder 636, and the third fixed column abuts against the outer surface of the connecting column 112.

[0053] Of course, in other embodiments, in one connection group 111, the first rotating cylinder 634, the second rotating cylinder 635 and the third rotating cylinder 636 can also be fixed by ratchets and pawls. The pawl for fixing the first rotating cylinder 634 is arranged on the end surface of the first rotating cylinder 634 away from the reinforcing column 1111, and the ratchet for fixing the first rotating cylinder 634 is arranged on the outer surface of the second rotating cylinder 635.

[0054] like Figure 1 As shown, in this embodiment, a plurality of connecting members 51 are arranged in parallel. In this way, when the first adhesive film layer 40 is impacted, the impact force can be more evenly dispersed to the first connecting beam 11 and the second connecting beam 12 through the connecting members 51, thereby reducing the probability of the first adhesive film layer 40 and the reinforcing layer 50 being damaged due to a large impact force.

[0055] Preferably, the connecting member 51 is arranged in parallel with the third connecting beam. Of course, in other embodiments, there may be an angle between the connecting line 511 and the first connecting beam 11, the value of the angle is e, and the range of e is 60° to 89°. Specifically, the value of e may be 60°, 75°, 80° or 89°, so that the photovoltaic power generation device can cope with impacts from different directions.

[0056] like Figure 2 As shown, in this embodiment, the photovoltaic power generation device further includes a front film layer 70, which is arranged on the front side of the first adhesive film layer 40, and the photovoltaic power generation device further includes a second adhesive film layer 80, which is arranged between the power generation layer 20 and the back plate layer 30. The front film layer 70 can protect the first adhesive film layer 40, so that the photovoltaic power generation device has a better impact resistance. The second adhesive film layer 80 makes the contact between the power generation layer 20 and the back plate layer 30 softer, avoiding the power generation layer 20 and the back plate layer 30 from being hard contacted, which may cause damage to the power generation layer when the photovoltaic power generation device is impacted.

[0057] Preferably, the front film layer is a film, and the material of the film can be ETFE (ethylene-tetrafluoroethylene copolymer) or PTFE (polytetrafluoroethylene). Of course, it can also be other materials, but it should have the characteristics of strong weather resistance, high light transmittance and strong water resistance. The material of the first adhesive film layer 40 and the material of the second adhesive film layer 80 can be EVA (ethylene-vinyl acetate copolymer), POE (polyolefin elastomer) or EPE (expandable polyethylene). The back plate layer 30 is a photovoltaic back plate, and the structural type of the photovoltaic back plate can be KPF type (usually including polyvinylidene fluoride film, polyethylene terephthalate, fluorine film) or KPC type (usually including polyvinylidene fluoride, polyethylene terephthalate, fluoroethylene and vinyl ether copolymer), etc., of course, it can also be other types.

[0058] Specifically, in this embodiment, the first adhesive film layer 40 is entirely located within the frame 10, and the front film layer 70 protrudes from the frame 10. Of course, in other embodiments, a partial structure of the second layer of the first adhesive film layer 40 is located within the frame 10, and another partial structure of the second layer is located outside the frame 10, and the edge of the partial structure located outside the frame 10 is covered on the frame 10, so that the frame 10, the first traction line 611, the second traction line 621, and the third traction line can be protected.

[0059] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0060] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0061] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
