[0024] First, refer to Figure 2 In this embodiment, the driving assembly includes a mounting plate 14, a motor 15, a third rotating rod 16 and a connecting column 17, the mounting plate 14 is fixedly connected to the base frame 1, the motor 15 is installed on the mounting plate 14, the third rotating rod 16 is fixedly connected to the output shaft of the motor 15, and the connecting column 17 is rotatably connected to the third rotating rod 16, and the connecting column 17 is rotatably connected with the first rotating rod 7 and the second rotating rod 8.

[0025] The mounting plate 14 is firmly fixed on the base frame 1 as a basic supporting component of the driving assembly, which provides a stable mounting platform for the motor 15 to ensure that the motor 15 will not shake or displace during operation. The motor 15 is mounted on the mounting plate 14, and its position and fixing mode are carefully designed to ensure that the output shaft of the motor 15 can be accurately connected with the third rotating rod 16. The third rotating rod 16 is tightly fixed on the output shaft of the motor 15, and when the motor 15 starts, the rotation of the output shaft can be directly transmitted to the third rotating rod 16. The connecting column 17 is rotatably connected to the third rotating rod 16, and this rotatable connection allows the connecting column 17 to rotate flexibly on the third rotating rod 16. At the same time, the connecting column 17 is rotatably connected with the first rotating rod 7 and the second rotating rod 8, forming a complete transmission link.

[0026] Then, referring to Figure 3 In this embodiment, the positioning assembly includes positioning shafts 18 and positioning rubbers 19. The positioning shafts 18 are detachably connected to the moving frame 9, and each positioning rubber 19 is fixedly connected to the positioning shaft 18 and uniformly arranged on the positioning shaft 18. Each positioning rubber 19 is in contact with the top of the solar panel 4.

[0027] The positioning shafts 18 are detachably connected to the moving frame 9, which facilitates the installation and maintenance of the moving frame 9. During the installation of the moving frame 9, the positioning shafts 18 are first installed at the corresponding positions on the moving frame 9, and the positioning rubbers 19 are uniformly arranged on the positioning shafts 18, with each positioning rubber 19 being in close contact with the top of the solar panel 4. The material of the positioning rubbers 19 has certain elasticity and friction, which can provide stable friction between the moving frame 9 and the solar panel 4 to prevent the moving frame 9 from sliding or deviating during cleaning. The first sprockets 20 are fixedly connected to the corresponding sliding wheels 11, and when the sliding wheels 11 rotate, the first sprockets 20 will rotate synchronously. The second sprocket 21 is fixedly connected to the cleaning shaft 12, and the rotation of the cleaning shaft 12 is closely related to the rotation of the second sprocket 21.

[0028] Finally, referring to Figure 4 In this embodiment, the power assembly includes first sprockets 20, a second sprocket 21, an electric shaft 22, a third sprocket 23, and a chain 24. Each first sprocket 20 is fixedly connected to a corresponding sliding wheel 11, and the second sprocket 21 is fixedly connected to the cleaning shaft 12. The electric shaft 22 is rotatably connected to the moving frame 9, and the third sprocket 23 is fixedly connected to the electric shaft 22. The chain 24 is transmissionally connected between the first sprockets 20, the second sprocket 21, and the third sprocket 23.

[0029] The electric shaft 22 is rotatably connected to the moving frame 9, and provides a power source for the whole power assembly. The third sprocket 23 is fixedly connected to the electric shaft 22. When the electric shaft 22 is started to rotate, the third sprocket 23 rotates with it. Since the chain 24 is in transmission connection among the first sprocket 20, the second sprocket 21 and the third sprocket 23, the rotation of the third sprocket 23 is transmitted to the first sprocket 20 and the second sprocket 21 through the chain 24. The rotation of the first sprocket 20 drives the sliding wheel 11 to rotate. The sliding wheel 11 rotates on the fixed rod 10 and is in sliding connection with the inside of the sliding groove on both sides of the solar panel 4, so that the moving frame 9 moves on the solar panel 4. At the same time, the rotation of the second sprocket 21 drives the cleaning shaft 12 to rotate, and the rotation of the cleaning shaft 12 further cleans the surface of the solar panel 4. For example, when the moving frame 9 moves from one end of the solar panel 4 to the other end, the cleaning shaft 12 rotates continuously, and the rubber plate 13 wipes the surface of the solar panel 4. The two cooperate to achieve comprehensive cleaning of the surface of the solar panel 4, remove dust, stains and other impurities, and improve the power generation efficiency of the solar panel 4.

[0030] Working principle:

[0031] When it is necessary to adjust the angle of the solar panel 4, the worker starts the motor 15 carried by the mounting plate 14 mounted on the chassis 1. The output shaft of the motor 15 drives the third rotating rod 16 to rotate. The connecting column 17 fixedly connected to the third rotating rod 16 rotates with it. The connecting column 17 is in rotational connection with the first rotating rod 7 and the second rotating rod 8, thereby driving the first rotating rod 7 and the second rotating rod 8 to rotate. The first rotating rod 7 is rotatably connected to the inside of the first connecting block 5 at the bottom of the solar panel 4. The second rotating rod 8 is rotatably connected to the inside of the second connecting block 6 at the top of the chassis 1 and is connected with the first rotating rod 7. Such rotation makes the solar panel 4 rotate around the bearing 3, thereby achieving angle adjustment.

[0032] Before cleaning the solar panel 4, the moving frame 9 is installed on the solar panel 4. The positioning shaft 18 in the positioning assembly is detachably installed on the moving frame 9. The evenly arranged positioning rubbers 19 on the positioning shaft 18 are in contact with the top of the solar panel 4, thereby stably positioning the moving frame 9 on the surface of the solar panel 4. The worker starts the electric shaft 22 to rotate. The third sprocket 23 fixedly connected to the electric shaft 22 rotates with it. Since the chain 24 is in transmission connection among the first sprocket 20, the second sprocket 21 and the third sprocket 23, and the first sprocket 20 is fixedly connected to the sliding wheel 11, the sliding wheel 11 is rotatably connected to the fixed rod 10 on both sides of the moving frame 9 and is in sliding connection with the inside of the sliding groove on both sides of the solar panel 4, the rotation of the electric shaft 22 drives the sliding wheel 11 to rotate through the chain 24, thereby making the moving frame 9 move on the top of the solar panel 4 along the sliding groove.

Accordingly, the description is to be regarded as illustrative in nature and not as restrictive.
