Description

Technical Field

[0001] The utility model relates to the field of photovoltaic cleaning, in particular to a synchronous walking device of a large-span photovoltaic cleaning robot. Background Art

[0002] With the promotion of distributed photovoltaics, more and more photovoltaics are installed on industrial and commercial roofs. In order to install as many photovoltaic modules as possible, most roofs are laid in a continuous manner. This brings difficulties to the subsequent manual operation and maintenance and cleaning. With the application of photovoltaic cleaners, the cleaning problem of large photovoltaic arrays can be well solved.

[0003] The existing photovoltaic cleaning robot is long and narrow in shape, with independent drive mechanisms at both ends. The drive mechanisms at both ends need to move in the same direction synchronously to ensure that the photovoltaic cleaning robot moves in that direction as a whole, thereby completing the cleaning work of a long row of photovoltaic panels.

[0004] However, the current synchronous walking device cannot meet the walking requirements of long-span photovoltaic cleaners. Even a small overall offset angle will cause the walking distance of the driving mechanisms at both ends to differ greatly, causing the machine to get stuck. Utility Model Content

If the detected number is the same, it means that the first and second fixed shells have traveled the same distance. When the number of through holes detected by the first fixed shell is greater or less than that of the second fixed shell, the first and second fixed shells slow down or speed up. A comparison is performed at short intervals. This process is repeated to ensure that the first and second fixed shells travel synchronously.

[0014] 2. The cleaning assembly can be used to clean the inside of the track to prevent debris from affecting the movement and stability of the first and second fixed shells.

While moving, the photoelectric sensors 7 on the first fixed shell 1 and the second fixed shell 2 detect the number of through holes 10 passed on the track 9. When the number of detection comparisons by the photoelectric sensors 7 on the first fixed shell 1 and the second fixed shell 2 is the same, it means that the distance traveled by the first fixed shell 1 and the second fixed shell 2 is the same.
