[0029] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments or drawings are used to illustrate the present utility model, but not to limit the scope of the present utility model.

[0030] Embodiment 1:

[0031] A photovoltaic panel fastening structure, as Figures 1 to 5 shown, includes a buckle housing 1, a buckle pull shaft 2, and a hook 3. A card slot 4 is provided on the side of the buckle housing 1. An upper bearing platform 5 and a lower bearing platform 6 are provided on the buckle housing 1 at the upper and lower ends of the card slot 4 respectively. The buckle pull shaft 2 vertically penetrates the buckle housing 1. The hook 3 is connected to the bottom of the buckle pull shaft 2. A locking component 10 is installed at the top of the buckle pull shaft 2. The locking component 10 is used to control the movement of the buckle pull shaft 2 relative to the buckle housing 1.

[0032] The photovoltaic panel 40 is installed on the purlin 41. The purlin 41 has a concave-shaped structure. The installation steps of the photovoltaic panel 40 are as follows: The clamp on the external mechanical part simultaneously grabs the photovoltaic panel 40 and the buckle housing 1, and controls the buckle housing 1 to lean against the side of the photovoltaic panel 40. The photovoltaic panel 40 contacts the inner wall of the card slot 4, and the upper supporting platform 5 abuts against the upper end surface of the photovoltaic panel 40. Then, the photovoltaic panel 40 is placed on the purlin 41. During this process, the claw 3 moves from the opening above the purlin 41 to the inside of the purlin 41. Finally, the locking assembly 10 controls the buckle pull shaft 2 to move upward relative to the buckle housing 1. The buckle pull shaft 2 drives the claw 3 to abut against the upper end of the inner wall of the purlin 41. The upper supporting platform 5 and the claw 3 cooperate to clamp the photovoltaic panel 40 and the purlin 41, completing the installation operation of the photovoltaic panel 40.

[0033] The cooperation of the buckle housing 1, the buckle pull shaft 2, and the claw 3 simplifies the installation steps of the photovoltaic panel 40. Except for the conventional action of placing the photovoltaic panel 40 on the purlin 41, only by controlling the buckle housing 1 to closely lean against the side of the photovoltaic panel 40 and controlling the buckle pull shaft 2 to move relative to the buckle housing 1 through the locking assembly 10, the upper supporting platform 5 and the claw 3 can cooperate to clamp the photovoltaic panel 40 and the purlin 41, completing the installation operation of the photovoltaic panel 40. The installation steps are simple and there is no restriction on the operating space, which is convenient for using the robotic arm to realize the automatic installation work of the photovoltaic panel 40.

[0034] The upper supporting platform 5 and the lower supporting platform 6 are in surface contact with the photovoltaic panel 40. Due to the existence of the supporting surface, the clamping force can be reduced while maintaining an effective clamping effect, reducing the deformation of the photovoltaic panel 40.

[0035] As Figure 5 shown, the claw 3 is rotatably connected to the buckle pull shaft 2 through a pin 7. A torsion spring 8 is installed in the middle of the pin 7. One end of the torsion spring 8 abuts against the buckle pull shaft 2, and the other end of the torsion spring 8 abuts against the claw 3. Under the action of the torsion spring 8, without performing additional operating steps on the claw 3, it can smoothly move into the purlin 41 without affecting the subsequent locking operation controlled by the locking assembly 10.

[0036] The head of the upper supporting platform 5 is provided with a limiting rib 9. After the buckle housing 1 is leaned against the side of the photovoltaic panel 40, the limiting rib 9 can be stuck on the edge of the photovoltaic panel 40 to prevent the position of the buckle housing 1 from shifting during the movement.

[0037] As Figure 4As shown in the figure, the locking assembly 10 includes a first tightening bolt 11 and a locking pin 12. The first tightening bolt 11 is installed at the upper end of the buckle pulling shaft 2 in a threaded connection manner. The first tightening bolt 11 is located above the buckle housing 1. An axially distributed first limiting hole 13 is provided in the middle of the buckle pulling shaft 2. The locking pin 12 is horizontally installed on the buckle housing 1. The locking pin 12 horizontally passes through the first limiting hole 13. A lock washer 14 is installed on the buckle pulling shaft 2 between the first tightening bolt 11 and the buckle housing 1.

[0038] The locking pin 12 can limit the rotation of the buckle pulling shaft 2. By rotating the first tightening bolt 11, the relative upward movement of the buckle pulling shaft 2 with respect to the buckle housing 1 can be controlled, realizing the function of the hook claw 3 moving upward in the purlin 41 to clamp the photovoltaic panel 40. The rotation of the first tightening bolt 11 can be directly controlled by an electric wrench loaded by a robotic arm, which has the advantage of automated installation.

[0039] Embodiment 2:

[0040] As Figure 6 and Figure 7 shown in the figure, the locking assembly 10 includes a wedge-shaped block 21 and a second tightening bolt 22. A horizontally distributed positioning hole 23 is provided on the buckle housing 1. An axially distributed second limiting hole 24 is provided on the buckle pulling shaft 2. The positioning hole 23 communicates with the second limiting hole 24. The wedge-shaped block 21 is installed in the positioning hole 23 and passes through the second limiting hole 24. A screw rod 25 extending to the outside of the buckle housing 1 is provided at the head of the wedge-shaped block 21. The second tightening bolt 22 is installed on the screw rod 25. The upper end surface of the wedge-shaped block 21 is an inclined surface that slopes downward toward the head. The upper end surface of the wedge-shaped block 21 contacts the upper end inner wall of the second limiting hole 24.

[0041] The positioning hole 23 restricts the moving direction of the wedge-shaped block 21. By rotating the second tightening bolt 22, the movement of the wedge-shaped block 21 in the direction of the second tightening bolt 22 can be controlled. With the cooperation of the upper inclined surface of the wedge-shaped block 21 and the second limiting hole 24, the relative upward movement of the buckle pulling shaft 2 with respect to the buckle housing 1 can be controlled, realizing the function of the hook claw 3 moving upward in the purlin to clamp the photovoltaic panel. The rotation of the second tightening bolt 22 can be directly controlled by an electric wrench loaded by a robotic arm, which has the advantage of automated installation.

[0042] Embodiment 3:

[0043] As Figure 8 and Figure 9As shown in the figure, the locking assembly 10 includes a connecting rod 31 and a pressing rod 32. The pressing rod 32 is installed on the buckle pulling shaft 2, and the connecting rod 31 is installed on the top of the buckle housing 1 and connected to the pressing rod 32. The connection modes among the buckle pulling shaft 2, the connecting rod 31, and the pressing rod 32 are all rotational connections. In the initial state, the connection point between the pressing rod 32 and the buckle pulling shaft 2 is located below the connection point between the pressing rod 32 and the connecting rod 31. A limiting rod 33 is arranged on the side of the connecting rod 31. The limiting rod 33 limits the maximum rotation angle of the pressing rod 32.

[0044] Under the action of the connecting rod 31, by rotating the pressing rod 32, the relative upward movement of the buckle pulling shaft 2 with respect to the buckle housing 1 can be controlled, realizing the function of the hook 3 moving upward in the purlin 41 to clamp the photovoltaic panel. It has the advantage of simple operation actions. Not only is it convenient for manual operation, but also the robotic arm can achieve this operation with simple control instructions and control structures.

[0045] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
