Further, each washing zone 10a includes at least one solar panel 11. And the number of solar panels 11 in the width direction in each washing zone 10a is the same. Of course, in some embodiments, the number of solar panels 11 in each washing zone 10a may also be two, three, four, five or other numbers. It is understood that the number of solar panels 11 in each cleaning zone 10a can be adjusted according to the actual situation, and therefore, the number of solar panels 11 in the cleaning zone 10a is not limited in this embodiment.

The intelligent cleaning module 100 starts to enter the second cleaning area 10a, at this time, the universal traveling mechanism 120 at the left end of the cleaning mechanism 110 travels to the second traveling guide rail 212 at the lower end of the first cleaning area 10a along the first transition guide rail 220, and the universal traveling mechanism 120 at the right end of the cleaning mechanism 110 travels to the second traveling guide rail 212 in the second cleaning area 10a along the second transition guide rail 231. When the universal traveling mechanism 120 at the left end of the cleaning mechanism 110 is detected by the detection mechanism 240 on the second traveling guide rail 212, the rail changing mechanism 230 executes a rail changing operation, so that the middle first traveling guide rail 211 is conducted with the second traveling guide rail 212 at the lower end of the first cleaning area 10a through the second transition guide rail 231, and then the whole intelligent cleaning module 100 completely enters the second cleaning area 10 a.

The intelligent cleaning module 100 returns to the initial position: the first way is to return according to the original cleaning path, and certainly, cleaning can be carried out again in the returning process so as to improve the cleaning effect. In the second mode, the track is switched by the track switching mechanism 230 located at the upper end of the middle first travel rail 211 to return to the first cleaning zone 10 a.

Wherein, the path of the intelligent cleaning module 100 for cleaning all the cleaning areas 10a by the rail-changing action of the rail-changing mechanism 230 is as shown in fig. 5.

Referring to fig. 6, a plurality of running rails 210 are shown in fig. 6 dividing the photovoltaic panel 10 into two "Jiong" and two "mouth" shaped washing zones 10 a. Wherein, the path of the intelligent cleaning module 100 for cleaning all the cleaning areas 10a by the rail-changing action of the rail-changing mechanism 230 is shown in fig. 6.
