Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning tools, and particularly relates to a cleaning tool for photovoltaic panels. Background Art

[0002] The main tools for manual cleaning of photovoltaic panels are single-disk brushes, double-disk brushes and single-roller brushes. Among them, the diameter of the single-disk brush is generally 300-350 mm, and the cleaning width is small, resulting in low cleaning efficiency. At the same time, when the edge of the single-disk brush touches protrusions such as the frame or pressing block of the photovoltaic panel, the rotation balance of the disk brush is broken, resulting in poor controllability. The controllability of the double-disk brush is better than that of the single-disk brush, and the cleaning efficiency is also higher than that of the single-disk brush. However, there is a certain gap between the two brush disks of the double-disk brush, resulting in poor scrubbing effect at the gap part. If this is to be compensated, the disk brush needs to be moved multiple times, increasing the labor intensity and also affecting the cleaning efficiency. At the same time, limited by the motor power and the weight of the whole machine, the diameter of the disk brush cannot be enlarged without limit. Therefore, the diameter of the single-disk brush generally does not exceed 320 mm, and the cleaning width of the double-disk brush generally does not exceed 650 mm, which seriously limits the improvement of cleaning efficiency.
