Opposite assembly parts 11 are arranged at the two ends of the support 1 along the length direction, wherein one anti-falling assembly 4, one limiting assembly 3 and one walking assembly 2 are sequentially assembled on each assembly part 11 along the first direction.

Even if the cleaning mechanism overturns in a strong wind environment, the anti-falling assembly 4 can hook the bottom surface of the photovoltaic module 100, and at the same time the frame of the photovoltaic module 100 blocks the cleaning mechanism, so that even if the cleaning mechanism overturns, the cleaning mechanism can also be prevented from falling off the photovoltaic module 100, effectively reducing economic losses. The rolling brush assembly 5 is assembled on the support 1, and when the walking mechanism is running, the rolling brush assembly 5 cleans and removes dust from the surface of the photovoltaic module 100, so as to ensure the power generation rate of the photovoltaic module 100. The rolling brush assembly 5 is arranged between the limiting assembly 3 and the anti-falling assembly 4, which can avoid the layout interference between the rolling brush assembly 5, the walking assembly 2, the limiting assembly 3 and the anti-falling assembly 4, and improve the rationality of the layout of the cleaning mechanism.

When the walking mechanism operates, the first driving member 53 drives the rotating shaft 51 to operate, and the rotating shaft 51 drives the rolling brush 52 to rotate, so that the cleaning mechanism can clean the surface of the photovoltaic module 100 during movement. Specifically, the rotating shaft 51 is arranged between the two assembling members 11, which further improves the rationality of the layout of the cleaning mechanism. In this embodiment, the first driving member 53 can be a driving motor.

[0039] In the embodiment, the limiting assembly 3 comprises a first assembling frame 31, a through shaft 32 and two limiting wheels 33, wherein the first assembling frame 31 is fixedly connected with the assembling member 11, the through shaft 32 is vertically arranged on one side of the assembling member 11 through the first assembling frame 31, and the two limiting wheels 33 are respectively rotationally arranged at the two ends of the through shaft 32, and the lower limiting wheel 33 is attached with the side of the photovoltaic module 100. The running range of the cleaning mechanism is limited by the limiting wheel 33, the limiting wheel 33 will not damage the side of the photovoltaic module 100, and the smoothness of the cleaning mechanism running on the photovoltaic module 100 is ensured. Since different photovoltaic modules 100 are laid in different positions, the cleaning mechanism needs to be flipped for bidirectional cleaning or reciprocating cleaning according to the laying position of the photovoltaic module 100 or the cleaning effect during the cleaning operation, and the limiting wheel 33 is arranged at the two ends of the through shaft 32, so that the limiting of the cleaning mechanism by the limiting wheel 33 is not affected even after the cleaning mechanism is flipped, and the rationality of the cleaning mechanism design is improved. It is preferred that the through shaft 32 is arranged on the side of the assembling member 11 close to the photovoltaic module 100, so that the layout of the first driving member 53 and the second driving member 21 is facilitated, and the rationality of the cleaning mechanism layout is further improved.

[0042] In the embodiment, the anti-falling assembly 4 comprises a second assembling frame 41, a connecting shaft 42, a stepping motor 43 and two anti-falling pieces 44, wherein the second assembling frame 41 is fixed with the assembling piece 11, the stepping motor 43 is connected with the second assembling frame 41, the stepping motor 43 is drivingly connected with the connecting shaft 42, the stepping motor 43 vertically places the connecting shaft 42 on one side of the assembling piece 11, and the two anti-falling pieces 44 are vertically connected at two ends of the connecting shaft 42 respectively. By controlling the movement of the stepping motor 43, the connecting shaft 42 can be driven to rotate, and then the orientation of the anti-falling piece 44 can be adjusted, so that the anti-falling piece 44 can be selectively placed below the photovoltaic module 100. When the cleaning mechanism is placed on the photovoltaic module 100, the anti-falling piece 44 can be placed below the photovoltaic module 100 by driving the stepping motor 43. If the cleaning mechanism is turned over during operation, the anti-falling piece 44 can hook the bottom surface of the photovoltaic module 100 to prevent the cleaning mechanism from falling. When it is necessary to turn over or remove the cleaning mechanism from the photovoltaic module 100, the anti-falling piece 44 can be driven to be parallel to the side surface of the photovoltaic module 100 or away from the photovoltaic module 100 by the stepping motor 43, so as to realize the quick turning or removal of the cleaning mechanism. The two anti-falling pieces 44 are arranged at the two ends of the connecting shaft 42, which can still prevent the cleaning mechanism from falling from the photovoltaic module 100 after the cleaning mechanism is turned over, and improves the rationality of the design of the cleaning mechanism. In the embodiment, the stepping motor 43 is a conventional technology in the mechanical field, which will not be described here.

[0043] Specifically, the second assembling frame 41 comprises a fourth connecting plate, a fifth connecting plate and a sixth connecting plate connected vertically in sequence, wherein the fifth connecting plate is fixedly connected with the assembling piece 11 through bolts, the fourth connecting plate and the sixth connecting plate are opposite in the vertical direction, the stepping motor 43 is arranged between the fourth connecting plate and the sixth connecting plate, and the connecting shaft 42 penetrates the fourth connecting plate, the stepping motor 43 and the sixth connecting plate in sequence to realize the driving connection between the stepping motor 43 and the connecting shaft 42 and arrange the connecting shaft 42 on one side of the assembling piece 11. The stepping motor 43 is fixed on the sixth connecting plate through bolts. Preferably, the connecting shaft 42 is arranged on the side of the assembling piece 11 away from the photovoltaic module 100 to avoid interference between the connecting shaft 42 and the photovoltaic module 100 when the cleaning mechanism operates, thereby further improving the rationality of the design of the cleaning mechanism.

The proximity switch 46 is in communication connection with the stepping motor 43, and the stepping motor 43 stops rotating when the proximity switch 46 detects the anti-falling shaft 441. Since the fixed plate 45 faces the assembling piece 11, when the proximity switch 46 detects the anti-falling shaft 441, the anti-falling shaft 441 is rotated to the lower side of the photovoltaic module 100 by the stepping motor 43 at this time, that is, the anti-falling wheel 442 is arranged on the lower side of the photovoltaic module 100. Subsequently, the proximity switch 46 communicates a signal to the stepping motor 43, and the stepping motor 43 stops working, thereby avoiding manual control to stop the stepping motor 43 from working and further improving the automation degree of the cleaning mechanism. In the embodiment, the proximity switch 46 and the stepping motor 43 can be connected through Bluetooth communication. The Bluetooth communication is a conventional knowledge in the communication field, and will not be described here. Preferably, a program can be burned in the stepping motor 43, and the stepping motor 43 is paused for 1S-2S after each rotation of 90 degrees to ensure that the proximity switch 46 accurately detects the anti-falling shaft 441. The program burning in the stepping motor 43 belongs to a conventional technical means in the software control field and does not belong to the key protection content of the utility model.
