[0028] Furthermore, the technical fields and installation methods involved in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Specific Implementation Example 1: Please refer to... Figures 1-7A photovoltaic panel hoisting device for photovoltaic construction includes a base 1, a tilting and adjusting seat 2, a moving component 3, and an installation component 4. The base 1 includes support frames 11 symmetrically arranged on both sides, and a tilting and adjusting seat 2 is located in the middle of the base 1. The tilting and adjusting seat 2 is movably connected to the two support frames 11 on both sides. The base 1 drives the tilting and adjusting seat 2 to rise and fall through a sprocket and chain structure. A rotating seat 22 is fixedly arranged in the middle of the tilting and adjusting seat 2. The rotating seat 22 is rotatably connected to the middle of the moving component 3. The rotating seat 22 drives the moving component 3 to rotate through a worm gear structure. The moving component 3 includes a movable connecting member 35, and an installation component 4 is rotatably arranged on the connecting member 35. The installation component 4 includes a top plate 41, and a suction cup 49 is installed on the side of the top plate 41 away from the moving component 3. The suction cup 49 adsorbs the photovoltaic panel 5.

[0030] The base 1 has four casters 14 installed at its bottom corners to move the photovoltaic panel 5 hoisting device. The casters 14 brake automatically when in position. A base support 111 is fixedly installed at the bottom of the support frame 11. Support legs 17 are rotatably mounted at the four corners of the base support 111. These support legs 17 typically use a cylinder structure, are telescopic and adjustable, and are suitable for uneven ground, improving stability during photovoltaic panel 5 installation. A lifting cylinder 12 is vertically installed in the middle of the support frame 11. A connecting plate 18 is fixedly connected to the telescopic end of the lifting cylinder 12. Lifting slide rods 13 are fixedly installed at both ends of the lower surface of the connecting plate 18. The lower part of the sliding rod 13 passes through the support frame 11 and is slidably connected to the support frame 11. Chain seats 15 are respectively installed at both ends of the upper surface of the connecting plate 18. A sprocket is rotatably installed in the chain seat 15. A lifting chain 16 is wound around the sprocket. One end of the lifting chain 16 is fixedly connected to the fixing block 21 fixedly installed at the end of the tilting adjustment seat 2, and the other end is fixedly connected to the top of the support frame 11. The sprocket and the lifting chain 16 are connected in a transmission. The extension or retraction end of the lifting cylinder 12 extends or retracts, driving the connecting plate 18 and the chain seat 15 to rise or fall, thereby driving the lifting chain 16 to move, and in turn driving the tilting adjustment seat 2 to rise or fall.

[0031] A worm gear 24 is rotatably mounted on one side of the rotating seat 22. The upper part of the rotating seat 22 is rotatably connected to the moving component 3 via a horizontally mounted rotating shaft. A worm wheel 23 is fixedly mounted on the end of the rotating shaft. The worm gear 24 is connected to the worm wheel 23 via a transmission. The worm gear 24 is driven to rotate by a rotating motor (not shown in the figure), thereby driving the moving component 3 to rotate around the rotating shaft. The rotation range of the moving component 3 is 0-180°.

[0032] When the photovoltaic panel 5 is installed on the mounting assembly 4, its long side can be set roughly vertically to facilitate movement and transportation, and to avoid collisions between the photovoltaic panel 5 and external components during the process of moving it under the photovoltaic bracket, thus preventing damage to the photovoltaic panel 5.

[0033] The movable component 3 also includes a mounting frame 31 and a rotating head 38. The mounting frame 31 is a rectangular frame structure. Connecting frames 311 are fixedly installed on both sides of the mounting frame 31, and a fixing plate 312 is fixedly installed between the two connecting frames 311. The mounting frame 31 is rotatably connected to the central shaft at the bottom of the rotating head 38 through the fixing plate 312. The rotating head 38 is fixedly connected to the rotating shaft of the rotating seat 22. The central shaft and the rotating shaft are perpendicular to each other. A driven gear 39 is fixedly installed on the central shaft. A driving gear 310 is meshed with one side of the driven gear 39. The driving gear 310 is rotatably installed on the rotating head 38 and is driven to rotate by an adjusting motor (not shown in the figure).

[0034] Movable parts 32 are fixedly installed on both sides of the mounting bracket 31. A sliding groove 322 is opened in the middle of the opposite side of the two movable parts 32. A through groove 321 is opened on the other side of the movable part 32. A slide bar 352 is slidably installed in the movable part 32. A mating rod 351 is fixedly installed on both sides of the connecting part 35. The mating rod 351 and the slide bar 352 are arranged perpendicularly. The end of the mating rod 351 passes through the sliding groove 322 and extends into the movable part 32 to be fixedly connected to the slide bar 352. The slide bar 352 passes through the through groove 321 and is fixedly connected to the moving rack 36. A fixing part 33 is fixedly installed in the middle of the side of the mounting bracket 31 facing the rotating head 38. A moving gear 34 is rotatably installed on the fixing part 33. The moving gear 34 is driven to rotate by a moving motor (not shown in the figure). The moving gear 34 is meshed with the moving rack 36.

[0035] A rotary motor 37 is installed on the other side of the connector 35. The output shaft of the rotary motor 37 is fixedly connected to the connecting shaft in the middle of the top plate 41. The connecting shaft is parallel to the central axis and drives the installation component 4 to rotate. The rotation range of the installation component 4 is 0-180°. The connector 35 rotates firstly with the rotating head 38 and the flip adjustment seat 2 to adjust the position of the long and short sides of the mounting frame 31 above the photovoltaic bracket, so that the moving component 3 can pass through the photovoltaic bracket and descend after flipping. The connector 35 rotates secondarily with the installation component 4 below to adjust the position of the photovoltaic panel 5, so that the long side of the photovoltaic panel 5 is parallel to the long side of the adjacent installed photovoltaic panel 5. It can also prevent the photovoltaic panel 5 from having errors in its installation position after adjustment, and avoid the adjustment of the moving component 3 from causing the overall adjustment, making the installation more accurate and the installation efficiency relatively high.

[0036] The top plate 41 is an X-shaped plate. The side of the top plate 41 away from the moving component 3 is coaxially fixedly connected to the mounting plate 48. The four corners of the mounting plate 48 are connected to suction cups 49 respectively. During hoisting, the base 1 is adjusted to drive the tilting adjustment seat 2, the moving component 3, and the photovoltaic panel 5 to rise vertically through the photovoltaic bracket, so that the photovoltaic panel 5 is above the photovoltaic bracket. The rotation motor is started to drive the moving component 3, the mounting component 4, and the photovoltaic panel 5 to rotate at a suitable angle so that the photovoltaic panel 5 is roughly parallel to the inclined surface of the photovoltaic bracket. The adjustment motor is started to drive the moving component 3 to rotate so that the long side of the moving component 3 is perpendicular to the long side of the photovoltaic panel 5, which facilitates the descent of the moving component 3 through the photovoltaic bracket and avoids collision between the moving component 3 and the photovoltaic bracket. During the movement, the long side of the moving component 3 is roughly vertical, reducing the floor space occupied.

[0037] Depending on the actual installation environment, move the device below the photovoltaic bracket, adjust the tilting adjustment seat 2 to a suitable height until the photovoltaic panel 5 is raised above the photovoltaic bracket, start the rotating motor to rotate the moving component 3 to a suitable angle, so that the photovoltaic panel 5 is tilted from a vertical state; adjust the mounting bracket 31 to rotate until its long side is approximately perpendicular to the long side of the installed photovoltaic panel 5, adjust the mounting component 4 to rotate the photovoltaic panel 5 so that its long side is approximately parallel to the long side of the adjacent installed photovoltaic panel 5, and adjust the connector 35 to move the photovoltaic panel 5 until it is close to the installed photovoltaic panel 5 on the photovoltaic bracket.

[0038] The brake system of the rotary motor 37 and the regulating motor itself can be reliably locked. It acts directly on the motor shaft through mechanical friction or electromagnetic force, and forcibly prevents the rotation of the motor shaft and the load when the power is cut off or the motor stops. The lifting cylinder 12 is generally pneumatically or electrically driven. Its specific structure is existing technology and will not be described in detail here.

[0039] The operating procedure and working principle of this device are as follows:

[0040] Install the photovoltaic panel 5 to be installed onto the device, adjust the suction cup 49 to adhere the photovoltaic panel 5, and move the device to the bottom of the photovoltaic support.

[0041] Adjust the tilting adjustment seat 2 to a suitable height until the photovoltaic panel 5 is raised above the photovoltaic bracket. Start the rotating motor to rotate the moving component 3 to a suitable angle, so that the photovoltaic panel 5 is rotated from a vertical state to an inclined state. Adjust the mounting bracket 31 to rotate until its long side is approximately perpendicular to the long side of the installed photovoltaic panel 5. Adjust the mounting component 4 to rotate the photovoltaic panel 5 so that its long side is approximately parallel to the long side of the adjacent installed photovoltaic panel 5. Adjust the connector 35 to move the photovoltaic panel 5 until it is close to the installed photovoltaic panel 5 on the photovoltaic bracket.

[0042] Lower the moving component 3 and the mounting component 4 below the photovoltaic bracket. If there is an error between the photovoltaic panel 5 and the installation position, adjust the connector 35 to move the photovoltaic panel 5, or adjust the mounting component 4 to rotate until the photovoltaic panel 5 corresponds to the installation position.

[0043] Adjust the base 1 to drive the tilting adjustment seat 2 and photovoltaic panel 5 to descend until the photovoltaic panel 5 contacts the installation position, fix the photovoltaic panel 5 to the photovoltaic bracket, release the suction cup 49, and adjust the device to reset; repeat the above steps to continue installing the remaining photovoltaic panels 5 until the installation is completed.

[0044] Specific Implementation Example 2: As shown in the example Figure 8 As shown, to prevent the long side of the mounting bracket 31 in the moving component 3 from colliding with the connecting plate 18 and its connecting parts during descent, a telescopic cylinder 25 is provided between the fixed block 21 and the rotating seat 22. This arrangement ensures sufficient space for the photovoltaic panel 5 to rotate above the photovoltaic support. The telescopic cylinder 25 is installed in the middle of the fixed block 21, and the telescopic end of the telescopic cylinder 25 is fixedly connected to the bottom of the rotating seat 22. Auxiliary rods 26 are fixedly provided at the four corners of the bottom of the rotating seat 22. The auxiliary rods 26 pass through the corresponding auxiliary holes on the fixed block 21, and the auxiliary rods 26 are slidably connected to the fixed block 21. The rotating adjustment seat... 2. Before the lifting process, the telescopic cylinder 25 is first adjusted to extend, driving the moving component 3, the mounting component 4, and the photovoltaic panel 5 to rise to the maximum extension of the telescopic cylinder 25. Then, the extension of the lifting cylinder 12 is adjusted to drive the tilting adjustment seat 2 and its connecting parts to rise as a whole. When driving the photovoltaic panel 5 to descend for installation, the extension of the lifting cylinder 12 is first adjusted to retract, driving the tilting adjustment seat 2 and its connecting parts to descend as a whole until the extension of the lifting cylinder 12 is at its minimum. If there is still a gap between the photovoltaic panel 5 and the photovoltaic bracket at this time, the extension of the telescopic cylinder 25 is retracted to drive the photovoltaic panel 5 to fall and be placed on the photovoltaic bracket.

[0045] The telescopic cylinder 25 is pneumatically or electrically driven, and its specific structure is existing technology, which will not be described in detail here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
