Further included in the cart 22 are road wheels 224 and a drive motor 225, as will be described in detail later. The cleaning device 1 can be moved to the next row of photovoltaic panel arrays 31 by the carrier cart 22.
The control system 4 is configured to control the cleaning device 1 and the driving motor of the carrier 22 to operate according to a cleaning task instruction stored in advance or input by a user, as shown in fig. 6.

Corresponding to the tail end position of each row of the photovoltaic panel arrays 31, induction points are arranged on the carrying track 21, and the number of the induction points is correspondingly set according to the row number of the photovoltaic panel arrays 31. When the carrier 22 travels to a sensing point on the carrier rail 21, that is, the carrier 22 has traveled to the next row of the photovoltaic panel arrays 31 while carrying the cleaning device 1, the position sensor 41 on the cleaning device 1 senses a sensing signal to the controller 41a, and the controller 41a controls the driving motor on the carrier 22 to stop working, so that the carrier 22 stops traveling.
The following is the workflow of the intelligent cleaning system 10 according to one embodiment of the present invention.
In general, the sweeping device 1 may be parked on the carrier vehicle 22 while not in operation, waiting for a work task instruction;
if the cleaning tasks are loaded manually or in advance in the control system 4, for example, the cleaning tasks are: cleaning apparatus 1 began cleaning every morning at 9:00 a day and ended after cleaning the first three rows of photovoltaic panel arrays.
Then according to the work task instruction, at 9:00 am, controller 41 begins to control cleaning device 1 to start and initialize;
then, the controller 41 starts the driving motor of the cleaning device 1 to transversely walk so as to leave the carrier vehicle 22, and continuously transversely walk on the photovoltaic panels 32 of the photovoltaic panel array 31 from the initial end of the first row of photovoltaic panel array 31, and the cleaning brushes on the photovoltaic panels 32 clean the photovoltaic panels 32;
then, when the cleaning device 1 travels to the end position of the first row of photovoltaic panel arrays 31, after the position detector 42 of the cleaning device 1 detects that the sensing point at the end of the photovoltaic panel array 31 sends out a sensing signal, the controller 41 controls the cleaning device 1 to drive the motor to turn, and the cleaning device travels towards the initial position of the photovoltaic panel arrays 31, and the travel process also executes a cleaning task, namely, each row of photovoltaic panel arrays 31 travels back and forth once for cleaning;
after cleaning a row of photovoltaic panel arrays 31, the cleaning device 1 returns to the carrier loader 22 and is in butt joint with the cleaning device 1 and the carrier loader 22 through the machine position butt joint device 43, the controller 41 controls the traveling mechanism 11 to stop working, and the machine position butt joint device 43 transmits a control signal and a power supply to the carrier loader 22;
then, the controller 41 drives the carrier 22 to travel along the carrier rail 21 until the position sensing device 41 senses that the rail corresponds to the sensing point set at the initial end of the next row of photovoltaic panels, the controller 41 controls the driving motor of the carrier 22 to stop working and controls the driving motor in the cleaning device 1 to start working, so that the cleaning device 1 starts to travel along the initial end of the next row of photovoltaic panel arrays 31 to the end.
Then, the controller 41 repeatedly controls the cleaning operation until the three rows of photovoltaic panel arrays 31 are cleaned, and the cleaning device 1 returns to the carrier loader to enter a standby state after the cleaning operation is finished.
The person skilled in the art will know that the position of the photovoltaic panel array 31 to be cleaned, for example the row 1, 3, 4 photovoltaic panel arrays, can also be flexibly set manually. The controller 41 controls the cleaning device 1 to return to the carrier loader 22 after the cleaning of the photovoltaic panel array in the 1 st row is finished according to the control instruction, and then to walk to the initial end of the photovoltaic panel array in the 3 rd row along the track; the controller 41 controls the carrier 22 to stop walking, then controls the cleaning device 1 to transversely walk to the 3 rd row photovoltaic panel array 31 until the set task is completed, and returns to the carrier 22 to stand by after the 4 th row photovoltaic panel array 31 is cleaned to wait for the next set task instruction.
Wherein, the work task instruction can be directly set manually on an input device (not shown in the figure) of the intelligent control system 10, or can be sent to the intelligent control system 10 through a remote control platform; the remote control platform can adopt different remote control terminals according to different user requirements, a user inputs a specific cleaning task through the remote control terminal, and the photovoltaic panel array needing cleaning is selected, for example, cleaning is started according to time input by the user, and cleaning is carried out according to the selected photovoltaic panel array.

However, there are also photovoltaic panels 32 in the back row of the photovoltaic panel array 3 that are not completely aligned with the photovoltaic panels 32 in the front row, but are offset by a distance, as shown in fig. 3 b. Therefore, the photovoltaic panels 32 in the same row are inclined at a certain angle relative to the north-south direction. Based on the above, the carrying rail 21 needs to be disposed in parallel with the straight direction along which the photovoltaic panel array 31 is laid in the north-south direction.
The carrying rails 21 can be laid on the ground where the photovoltaic panel array group 3 is laid, and can also be erected on the upper portion of the photovoltaic panel array group 3 through the supports 211, as shown in fig. 9, the carrying rails 21 which are arranged in an erecting mode can be beneficial to avoiding channels between photovoltaic panels in each row of the photovoltaic panel array 31, so that vehicles can conveniently drive in, maintenance of a power station can be performed, and construction requirements in other aspects can be met.

At least two sets of upper and lower traveling wheels 11 are arranged on the body corresponding to the cleaning device 1, and at least two upper and lower connecting rails are arranged on the connecting unit 222 corresponding to the traveling wheels 11 of the cleaning unit.
The docking unit 222 is in the same plane with the docked photovoltaic panel array 31 after docking with the photovoltaic panel array 31, as shown in fig. 11. The docking unit 222 may also form a slope, such as an upper slope or a lower slope, with respect to the docked photovoltaic panel array 31 after docking with the photovoltaic panel array 31, as shown in fig. 12. The slope may be arranged as gentle as possible so that the cleaning unit can walk from the photovoltaic panel array 31 onto the docking unit 222 without obstruction.
In the case of a staggered photovoltaic panel array, as shown in fig. 13a and 13b, a carrying rail 21 according to another embodiment of the present invention is provided. The carrying rail 21 comprises a first rail 211 arranged corresponding to the initial cleaning end of each row of photovoltaic panel arrays, the first rail 211 is perpendicular to a straight line formed by the horizontal arrangement of each row of photovoltaic panel arrays 31, and the length of the first rail 211 is not less than the side length of the panel corresponding to the north-south direction of the photovoltaic panel 32; an engaging track 212 for being disposed between the first tracks 211 to engage the first tracks 212.
