[0037] And a control system is arranged in the mobile base 5, and the control system is controlled and connected with the stacking mechanism and the lifting mechanism; in order to facilitate operation, a remote controller is also provided, and the remote controller is wirelessly connected with the control system.

[0038] Example 2, as Figure 1-Figure 2 As shown, the photovoltaic module transport device proposed by the present invention, compared with the first embodiment, this embodiment introduces the structure of the stacking mechanism in detail.

[0039] A material placement trough 6 is set on the mobile base 5, and the stacking mechanism includes a square rack 7 slidingly set in the material placement trough 6 in the vertical direction, a plurality of partitions 8 arranged side by side on the inner wall of the square rack 7, and a lifting device 11 for pushing the square rack 7 up and down.

The partition 8 can be set to be slightly inclined to further improve the stability of the photovoltaic component 4 when placed and prevent the photovoltaic component 4 from slipping down.

[0040] Example 3, as Figure 2-Figure 4 As shown, the photovoltaic module transport device proposed by the present invention, compared with the first or second embodiment, this embodiment introduces the structure of the positioning mechanism in detail.

[0041] The clamping assembly includes a U-shaped frame 13, U-shaped pallets 14 arranged at both ends of the bottom of the U-shaped frame 13, and a lifting ring 30 arranged on the U-shaped frame 13; the upper and lower ends of the photovoltaic component 4 are respectively inserted into the two U-shaped pallets 14. In order to ensure that the photovoltaic component 4 is smoothly inserted, the distance between the two U-shaped pallets 14 for placing the photovoltaic component 4 must be greater than the length of the photovoltaic component 4. The height of the U-shaped frame 13 is controlled by the lifting mechanism so that the photovoltaic component 4 can be directly inserted into the two U-shaped pallets 14 after being pushed out from the partition 8; in an optional embodiment, handles 15 are provided on both U-shaped pallets 14. When in use, holding the handles 15 facilitates pushing the positioning mechanism.

[0042] When the two horizontal fixing rods 3 are in the same distance from each other, the two U-shaped limiting plates 24 are respectively clamped on the two horizontal fixing rods 3. When the two horizontal fixing rods 3 are in the same distance from each other due to production, installation and other factors, the positioning mechanism cannot continue to move along the horizontal fixing rods. At this time, the adjusting rod 22 can be flipped upward so that the two U-shaped limiting plates 24 on one of the horizontal fixing rods 3 can be directly disengaged. In order to make the sliding more smooth, rollers 25 are rotatably provided on the inner walls of the three sides of the U-shaped limiting plate 24.

[0044] Furthermore, a strip groove 21 is provided on the slide 16, and the adjusting rod 22 passes through the slide 16 and the strip groove 21, and a worm gear 26 is provided on the adjusting rod 22, and the worm gear 26 is located in the strip groove 21; a support seat 29 is provided on the slide 16, and a worm 27 is rotatably provided on the support seat 29, and the worm 27 and the worm gear 26 are meshed, and knobs 28 are provided at both ends of the worm 27; by rotating the worm 27, the worm gear 26 and the adjusting rod 22 are driven to rotate, thereby changing the position and state of the U-shaped limit plate 24, and the U-shaped limit plate 24 is flipped to the bottom to limit and support the photovoltaic component 4 through the transverse fixing rod 3 so that it does not contact the transverse fixing rod 3. The U-shaped limit plate 24 is flipped upward a little to maintain the positioning while allowing the photovoltaic component 4 to fall on the transverse fixing rod 3, thereby positioning and installing the photovoltaic component 4, and after the U-shaped limit plate 24 is flipped upward at a large angle, the photovoltaic component 4 can be pushed into the U-shaped card plate 14.

[0045] Example 4, as Figure 1 As shown, the photovoltaic module handling device proposed by the present invention, compared with the third embodiment, this embodiment introduces the structure of the lifting mechanism in detail.

[0046] The lifting mechanism includes a turntable 31 rotatably arranged on the mobile base 5, a motor 32 arranged on the mobile base 5 to drive the turntable 31 to rotate, a multi-stage electric telescopic rod 33 vertically arranged on the turntable 31, a flat plate 34 arranged on the top of the multi-stage electric telescopic rod 33, and a rope unwinding device 35 arranged at the end of the flat plate 34. The rope unwinding device 35 releases or reels a rope 36. A hook 37 is arranged at the bottom of the rope 36. The lifting and positioning mechanism is lifted by the hook 37. Specifically, the hook 37 works in conjunction with the lifting ring 30; the control system is controlled and connected to the motor 32, the multi-stage electric telescopic rod 33 and the rope unwinding device 35; in an optional embodiment, the rope unwinding device 35 includes a shell, a winding motor arranged in the shell, and a winding wheel arranged on the output shaft of the winding motor, and the rope 36 is wound around the winding wheel.

[0047] Example 5, as Figure 5 As shown, a transport method based on the above-mentioned embodiment of the photovoltaic module transport device includes the following steps:

[0048] S1. Arrange multiple photovoltaic modules 4 in an orderly manner using a stacking mechanism, and then move the mobile base 5 to the vicinity of the mounting frame 1;

[0049] S2, fixing a photovoltaic module 4 by a positioning mechanism;

[0050] S3, the lifting mechanism lifts the positioning mechanism to a suitable height, adjusts the positioning mechanism so that it falls on the transverse fixing rod 3, and moves it to the installation position through the transverse fixing rod 3;

[0051] S4. Fix the photovoltaic modules and complete the transportation and installation.

[0052] In summary, when the present invention is in use, multiple photovoltaic modules 4 are placed on multiple partitions 8, and multiple photovoltaic modules 4 can be transported at a time. Then, the mobile base 5 is moved to the vicinity of the mounting frame 1, and the installation work is ready to begin. First, the worm 27 is rotated to flip the two support rods 23 and the U-shaped limit plate 24 on the right side upwards, and then the height of the square storage rack 7 is adjusted by the lifting device 11, and the photovoltaic module 4 on a partition 8 is pushed into the two U-shaped pallets 14. The photovoltaic module 4 is supported and lifted by the two U-shaped pallets 14, and then the support rod 23 and the U-shaped limit plate 24 on the right side are flipped downwards, and then the hook 37 is hung on the lifting ring 30, and the entire positioning mechanism is lifted by the multi-stage electric telescopic rod 33 and the positioning mechanism is moved to the appropriate position by the operation of the motor 32. The operator holds the positioning mechanism and aligns the U-shaped limit plate 24 with the horizontal fixed rod 3, and slowly lowers the positioning mechanism by the descent of the multi-stage electric telescopic rod 33. At this time, the photovoltaic module 4 is not in contact with the horizontal fixed rod 3 due to the support of the U-shaped limit plate 24, and the positioning mechanism is pushed. The photovoltaic module 4 is sent to the installation position by the positioning mechanism. It should be noted that if the photovoltaic module 4 has been installed on one side, the two support rods 23 and U-shaped limit plates 24 on that side need to be flipped upward when approaching the installation position to avoid the already installed photovoltaic module 4. At this time, the operator needs to slightly support the positioning mechanism to ensure the continued movement of the photovoltaic module 4. After moving to the installation position, the remaining U-shaped limit plates 24 are slightly flipped upward so that the photovoltaic module 4 is attached to the horizontal fixing rod 3. At this time, the photovoltaic module has been completely placed in place, and due to the positioning of the U-shaped limit plates 24, the photovoltaic module 4 is in a stable placement state. The operator only needs to tighten the bolts on both sides of the photovoltaic module 4 in turn. When installing the bolts, the gap left between the two inclined support rods 23 is completely operable and will not affect the installation of the photovoltaic module 4. After the photovoltaic module 4 is fixed, the positioning mechanism is moved in the opposite direction to disengage the U-shaped card plate 14 from the photovoltaic module 4, and then the positioning mechanism is moved to the initial position for reset. The entire installation process can be operated by one person.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
