Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] One side of the photovoltaic panel 1 is provided with second sockets 30 at the four corners, and the second plug rod 28 is plugged into the second socket 30. The other side of the support plate 2 is fixed with two fixing plates 19 by bolts. Two rotating holes are provided on one side of the two fixing plates 19. A connecting shaft 18 is rotatably connected in the two opposite rotating holes. The outer key of the connecting shaft 18 is connected to two retractable rollers 20. The outer sides of the multiple retractable rollers 20 are wrapped with pull ropes 7. The multiple pull ropes 7 pass through the support plate 2 and are fixed to the first fixing frame 5 respectively. The other side of the support plate 2 is fixed with multiple groups of first guide frames 6 and second guide frames 8 by bolts, and the pull ropes 7 bypass the first guide frames 6 and second guide frames 8. A power component is provided on the other side of the support plate 2 to drive the two connecting shafts 18 to rotate. A locking component is provided on one side of the support plate 2 to assist in fixing the photovoltaic panel 1, so that the locking component no longer assists in fixing the photovoltaic panel 1. Then the support plate 2 is rotated through the rotating shaft 13 and the support plate 2 is fixed by the plug-in component. The first fixing frame 5 will move downward under the action of gravity, and the first fixing frame 5 will drive the baffle plate 29 to move downward and stretch the pull rope 7. At this time, the photovoltaic panel 1 will follow the baffle plate 29 to fall slowly, so that the photovoltaic panel 1 falls onto the transport vehicle. When the photovoltaic panel 1 contacts the transport vehicle, the first fixing frame 5 continues to drive the baffle plate 29 to move downward, and because the photovoltaic panel 1 contacts the transport vehicle, the second plug rod 28 on the baffle plate 29 will be disengaged from the second socket 30 on the photovoltaic panel 1, so that the photovoltaic panel 1 is disassembled, and the staff does not need to carry the photovoltaic panel 1 from the bracket, which reduces the labor of the staff and can avoid the photovoltaic panel 1 from falling and being damaged, thereby improving the safety of replacing the photovoltaic panel 1.

[0030] In the present invention, the plug-in assembly includes a slide plate 3, which is arranged on the outside of the rotating shaft 13, and a slide groove 14 that penetrates the rotating shaft 13 is opened on one side of the rotating shaft 13. The slide plate 3 moves along the groove direction of the slide groove 14, and a plurality of first plug rods 15 are welded on one side of the slide plate 3. A plurality of first sockets 16 are opened on both sides of the support frame 4, and the first plug rods 15 are plugged into the first sockets 16. A spring 12 is arranged in the slide groove 14, and the two ends of the spring 12 are respectively fixed to the slide plate 3 and the rotating shaft 13. Two symmetrically distributed second magnetic plates 11 are bonded to the outside of the rotating shaft 13, and two symmetrically distributed first magnetic plates 10 are bonded to one side of the slide plate 3, and the first magnetic plates 10 and the first magnetic plates 10 are bonded to the second magnetic plates 11. The second magnetic plate 11 can be adsorbed, and the slide plate 3 is pulled to move along the slide groove 14. The slide plate 3 will squeeze the spring 12 and drive the first magnetic plate 10 and the first plug rod 15 to move. When the slide plate 3 moves to the first magnetic plate 10 and the second magnetic plate 11 are adsorbed, the slide plate 3 will be fixed. At this time, the first plug rod 15 will be separated from the first socket 16. At this time, the support plate 2 can be rotated through the rotating shaft 13, and the photovoltaic panel 1 on the support plate 2 is rotated downward. The slide plate 3 is moved to separate the first magnetic plate 10 from the second magnetic plate 11. At this time, the slide plate 3 will be reset under the action of the spring 12, so that the first plug rod 15 is inserted into the first socket 16 to fix the support plate 2;

[0031] In particular, the power assembly includes a second fixing frame 9, which is fixed to the other side of the support plate 2 by bolts, and a reduction motor is fixed to one side of the second fixing frame 9 by bolts, and one end of the reduction motor output shaft passes through the second fixing frame 9 and is connected to a worm 17 by a coupling, and one end of the two connecting shafts 18 is keyed to a worm gear 21, and the worm 17 is located between the two worm gears 21 and meshes with the two worm gears 21. When the reduction motor is started, the reduction motor will drive the worm 17 to rotate, and the worm 17 will drive the two worm gears 21 to rotate by meshing with the two worm gears 21, and the two worm gears 21 will drive the two connecting shafts 18 to rotate, and the locking assembly includes two slide rails 23, and the two slide rails 23 are fixed to one side of the support plate 2 by bolts, and the slide rail 23 is located between the support plate 2 and the photovoltaic panel 1, and one side of the slide rail 23 slides The slide 22 is movably connected, and a clamping plate 26 is welded on the top of the slide 22, and the clamping plate 26 is clamped with the photovoltaic panel 1. A through hole is opened on one side of the protrusion 27, and a bidirectional threaded rod 25 is rotatably connected in the through hole, and the bidirectional threaded rod 25 passes through the slide 22 and is threadedly connected to the slide 22. Knobs 24 for rotating the bidirectional threaded rod 25 are welded at both ends of the bidirectional threaded rod 25. The main photovoltaic panel 1 is clamped by the clamping plate 26, so that the photovoltaic panel 1 can be auxiliary fixed, and the photovoltaic panel 1 can be stably installed. When the photovoltaic panel 1 needs to be disassembled, the bidirectional threaded rod 25 is rotated, and the bidirectional threaded rod 25 will make the slide 22 move along the slide rail 23 through the threaded engagement between the slide 22, and the slide 22 will drive the clamping plate 26 to move, so that the clamping plate 26 is separated from the photovoltaic panel 1, and the photovoltaic panel 1 is no longer auxiliary fixed.

[0032] Working principle of this embodiment: When disassembly is required, the bidirectional threaded rod 25 is rotated, and the bidirectional threaded rod 25 engages with the thread between the slide 22 to make the slide 22 move along the slide rail 23, and the slide 22 drives the card plate 26 to move, so that the card plate 26 is separated from the photovoltaic panel 1, and then the slide plate 3 is pulled to move along the slide groove 14, and the slide plate 3 squeezes the spring 12 and drives the first magnetic plate 10 and the first plug rod 15 to move, and when the slide plate 3 moves to the first magnetic plate 10 and the second magnetic plate 11, the slide plate 3 is fixed. At this time, the first plug rod 15 will be disengaged from the first socket 16, and the support plate 2 can be rotated through the rotating shaft 13 to rotate the photovoltaic panel 1 on the support plate 2 downward. At this time, the baffle 29 will support the photovoltaic panel 1, and then the slide plate 3 is moved to disengage the first magnetic plate 10 from the second magnetic plate 11. At this time, the slide plate 3 will be reset under the action of the spring 12, so that the first plug rod 15 is inserted into the first socket 16 to fix the support plate 2. At this time, the transport vehicle is moved to the bottom of the photovoltaic panel 1, and then the reduction motor is started. The reduction motor drives the worm 17 to rotate, and the worm 17 drives the two worm wheels 21 to rotate by meshing with the two worm wheels 21. The two worm wheels 21 drive the two connecting shafts 18 to rotate, and the connecting shaft 18 drives the retracting roller 20 to rotate, so that the retracting roller 20 releases the pull rope 7. At this time, the pull rope 7 no longer pulls the first fixed frame 5, and the first fixed frame 5 moves downward under the action of gravity. The first fixed frame 5 drives the baffle 29 to move downward and stretch the pull rope 7. At this time, the photovoltaic panel 1 follows the baffle 29 to slow down. The photovoltaic panel 1 is slowly dropped onto the transport vehicle. When the photovoltaic panel 1 contacts the transport vehicle, the first fixing frame 5 continues to drive the baffle plate 29 to move downward. Since the photovoltaic panel 1 contacts the transport vehicle, the second plug rod 28 on the baffle plate 29 is disengaged from the second socket 30 on the photovoltaic panel 1, thereby disassembling the photovoltaic panel 1. The staff is not required to carry the photovoltaic panel 1 down from the bracket, which reduces the labor of the staff and avoids damage to the photovoltaic panel 1 due to the fall, thereby improving the safety of replacing the photovoltaic panel 1.
