| 摘要 |
The present invention concerns a mobile cleaning device (1) suitable for displacing along, and cleaning a series of adjacent tilted solar panels (20) aligned in a row and requiring therefor no superstructure fixed to said row of solar panels, said device comprising: A supporting frame (2) defining a cleaning plane (2A), on which are mounted: Cleaning means (4) suitable for cleaning a surface parallel to the cleaning plane (2A); Support means (9) for maintaining the supporting frame (2) substantially parallel to the surface to be cleaned during the displacement of the cleaning device along a row of solar panels (20); Guiding means (3) for guiding the displacement of the cleaning device along a row of solar panels (20), said guiding means (3) comprising at least two, preferably at least three separate guiding wheels (3A), which are aligned along a straight line parallel to the cleaning plane and adjacent to a first edge of the frame (2), each guiding wheel (3A) being mounted such as to rotate about an axis substantially normal to the cleaning plane (2A) and suitable for resting and rolling on the upper edge of the aligned solar panels (20) with the cleaning means (4) in cleaning contact with the surface to be cleaned. |
