When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] The present invention provides the following embodiments

[0041] Example 1

[0042] The embodiment of the present invention provides a lifting device for installing a photovoltaic panel assembly, such as Figure 1-5 As shown, it includes a lifting device bracket 1, on which two groups of annular transmission mechanisms 2 are arranged, on which a plurality of groups of lifting and placing frames 3 are arranged, and at the bottom of the lifting device bracket 1 a flexible moving component 4 is arranged.

[0043] The working principle and beneficial effects of the above technical solution are as follows: when working, the annular transmission mechanism 2 drives a number of lifting and placement racks 3 to lift in a circular manner, and stacking the photovoltaic panel assemblies on the lifting and placement racks 3 can not only realize the lifting of the photovoltaic panel assemblies, but also has higher lifting efficiency than traditional lifting devices, and can adapt to continuous operation. The design of the flexible moving component 4 facilitates the movement of the lifting device.

[0044] Example 2

[0045] On the basis of Example 1, the lifting device bracket 1 includes a side panel 100 and a side panel 2 101, the side panel 100 and the side panel 2 101 are fixedly connected at the top by a connecting rod 102, the side panel 100 and the side panel 2 101 are connected at the bottom by two symmetrically arranged connecting rods 2 103, and the flexible moving component 4 is connected between the side panels 100 and the bottom of the side panel 2 101;

[0046] The lifting device bracket 1 is also fixedly connected with an inclined loading plate 104 .

[0047] The working principle and beneficial effects of the above technical solution are as follows: the design of the side panel 100 and the side panel 2 101 increases the overall rigidity and stability of the device, and the use of the flexible mobile component 4 enables the device to move quickly at the work site, improving the construction efficiency and adaptability. At the same time, the design of the inclined loading plate 104 facilitates the loading and unloading of photovoltaic panel components.

[0048] Example 3

[0049] On the basis of Example 1, the annular transmission mechanism 2 includes two symmetrically arranged sprockets 1 200 and sprocket 2 201, and sprockets 1 200 and sprockets 2 201 are both rotatably connected to the lifting device bracket 1. Sprockets 1 200 and sprockets 2 201 are connected by a lifting chain 202, and the lifting chain 202 is meshed with sprockets 1 200 and sprockets 2 201.

[0050] The working principle and beneficial effects of the above technical solution are as follows: when working, the driving mechanism drives sprocket 2 201 to rotate, sprocket 201 drives the lifting chain 202 to transmit, and the lifting chain 202 drives sprocket 1 200 to rotate, thereby realizing the annular lifting action of the annular transmission mechanism 2. Through the combination of sprocket 1 200 and sprocket 2 201, a stable material lifting function is realized. The meshing transmission of the lifting chain 202 ensures the stability and reliability of the lifting process and can carry a larger load.

[0051] Example 4

[0052] On the basis of Example 3, the lifting and placing frame 3 includes two triangular connecting plates 300, one end of the two triangular connecting plates 300 is respectively fixedly connected to the lifting chains 202 corresponding to the two groups of annular transmission mechanisms 2, and the positions correspond to each other. The other ends of the two triangular connecting plates 300 are connected by an intermediate rod 301, and the two ends of the intermediate rod 301 are respectively rotatably connected to the top frame rod 302, and the two ends of the top frame rod 302 are hingedly connected to the wall rod 303, and the end of the wall rod 303 away from the top frame rod 302 is hingedly connected to the bearing bottom plate 304.

[0053] The working principle and beneficial effects of the above technical solution: during the working process, the triangular connecting plate 300 moves synchronously with the lifting chain 202, thereby driving several bearing base plates 304 to perform circular cyclic lifting actions in space. The lifting and placement frame 3 has a reasonable structure and can provide good support and protection for the photovoltaic panel assembly. Through the combination of the triangular connecting plate 300 and the intermediate rod 301, the overall stability and flexibility of the structure are achieved, ensuring the safety of the lifting process.

[0054] Example 5

[0055] On the basis of embodiment 4, it also includes an auxiliary mechanism 5, which is installed on the middle rod 301, and is used to assist the photovoltaic panel assembly in lifting. The auxiliary mechanism 5 is provided with a photovoltaic panel surface cleaning assembly 6;

[0056] The auxiliary mechanism 5 includes a driving sliding block 500, a mounting frame 1 501 and a mounting frame 2 502. The driving sliding block 500 is fixedly connected to the mounting frame 1 501. The mounting frame 1 501 and the mounting frame 2 502 are connected via a telescopic mechanism 503. An electric bidirectional lateral adjustment screw 504 is rotatably connected in the mounting frame 2 502. Two symmetrically arranged lateral adjustment nuts 505 are threadedly connected to the electric bidirectional lateral adjustment screw 504. A positioning arm 506 is fixedly connected to the lateral adjustment nut 505.

[0057] The second mounting frame 502 is provided with a retractable negative pressure surface cleaning assembly 507, which is used to clean the surface of the photovoltaic panel assembly;

[0058] The telescopic mechanism 503 includes a telescopic drive motor 5030, the output end of the telescopic drive motor 5030 is connected to a telescopic bidirectional lead screw 5031, the telescopic bidirectional lead screw 5031 is threadedly connected to two symmetrically arranged longitudinal adjustment nuts 5032, the longitudinal adjustment nuts 5032 are hingedly connected to cross links 5033, the two cross links 5033 are hinged in the middle, and one end of the two cross links 5033 away from the longitudinal adjustment nuts 5032 is hingedly connected to the second installation frame 502;

[0059] Two symmetrically arranged electric micro gears 5000 are rotatably connected in the driving sliding block 500 , and the electric micro gears 5000 are meshed with the racks on both sides of the middle rod 301 .

[0060] The working principle and beneficial effects of the above technical solution are as follows: if there are many photovoltaic panel assemblies stacked on a single bearing bottom plate 304, in order to ensure stability during the lifting process, the auxiliary mechanism 5 is used to assist in lifting, and the stability of the photovoltaic panel assembly is maintained during the lifting process. At the same time, after the lifting is in place, the photovoltaic panel assembly is cleaned on the surface by the photovoltaic panel surface cleaning assembly 6;

[0061] After the photovoltaic panel assembly is stacked and placed on the bearing base plate 304, the electric micro gear 5000 rotates and meshes with the racks on both sides of the intermediate rod 301 to drive the sliding block 500 to slide on the intermediate rod 301. When the sliding block 500 slides to a suitable position, the electric two-way lateral adjustment screw 504 rotates to drive the two lateral adjustment nuts 505 to move away from each other, and adjusts the distance between the two positioning arms 506 to a suitable distance, that is, the inner side of the positioning arm 506 can fit the side of the photovoltaic panel assembly when it is lowered. Then, the telescopic drive motor 5030 drives the telescopic two-way screw 5031 to rotate, and the telescopic two-way screw 5031 rotates to make the two longitudinal adjustment nuts 5032 move toward each other to a suitable distance. At this time, the positioning arm 506 is lowered to a suitable height, and then the lifting device starts to lift. During the lifting process, if the lifting rack 3 is bumped or tilted temporarily, the photovoltaic panel assembly on the bearing base plate 304 will not fall over under the action of gravity under the action of the positioning arm 506;

[0062] When cleaning the upper surface of the photovoltaic panel assembly, the telescopic mechanism 503 drives the retractable negative pressure surface cleaning assembly 507 to move downward until the working end is in contact with the upper surface of the photovoltaic panel assembly, and then the electric micro gear 5000 rotates and engages with the racks on both sides of the middle rod 301 to drive the sliding block 500 to slide on the middle rod 301, thereby achieving the traversal of the retractable negative pressure surface cleaning assembly 507 on the upper surface of the photovoltaic panel assembly, thereby cleaning the upper surface of the photovoltaic panel assembly and ensuring the surface cleanliness of the photovoltaic panel assembly.
