When using this multi-row photovoltaic panel group cleaning device to perform automatic cleaning of multi-row linear photovoltaic panel groups, follow the steps below:

In the first step, firstly, the multi-row photovoltaic battery panel group is arranged to be connected end-to-end between two adjacent rows, and three photovoltaic battery panels in a "y" shape are arranged at the connection between two adjacent rows, that is, The photovoltaic cell panels at the starting point or terminal end of one row protrude from the terminal photovoltaic cell panels of the other row.

In the second step, after the cleaning device completes the cleaning of a row of photovoltaic cell panels, the position sensor of the traveling mechanism sends a signal to the controller. The controller controls the running mechanism to cross directly to the back row. If the photovoltaic cell panel at the end point of the row is set outside the photovoltaic cell panel group in the rear row, the controller controls the traveling mechanism to return to the beginning of the photovoltaic cell panel at the end point of the row and then cross over to the back row.

In the third step, if the terminal photovoltaic cell panels of the rear row are set outside the row of photovoltaic cell panel groups, the traveling mechanism directly crosses to the rear row, and crosses forward to the connected rear row by controlling the front spanning wheels. On the first piece of photovoltaic cell board, adjust the walking angle of the front span wheel on the end surface of the photovoltaic cell board through the horizontal plane adjustment mechanism, such as the structure shown in accompanying drawing 2 and accompanying drawing 3, when the front spanning wheel arranged on the horizontal connecting rod After the wheel spans to the first photovoltaic cell panel in the next row, the front span wheel will swing on the horizontal connecting rod due to the force, and the clamping wheels of the front span wheel fall on both sides of the photovoltaic cell panel to ensure that the front span wheel Walking along the top surface of the photovoltaic panel, the distance between the two clamping wheels of the front spanning wheel is slightly larger than the thickness of the photovoltaic panel, and the traveling wheel continues to move forward following the front spanning wheel, so that the cleaning device can travel to the last step. The first photovoltaic panel in the row achieved a leap forward.

And if the level adjustment mechanism is driven by a horizontal motor, according to the angle between the two adjacent rows of photovoltaic panel groups, the horizontal motor drives the spanning wheel to rotate horizontally for a certain angle, and then rotate vertically to directly span to the next connected row. On the first photovoltaic panel in the row, the clamping wheels are clamped on both sides of the photovoltaic panel, and the traveling wheels follow it forward, thus achieving leapfrogging.

After the cleaning of the photovoltaic cell panel is completed, the driving wheel is driven back, the front spanning wheel is changed to the rear spanning wheel, and the rear spanning wheel is changed to the front spanning wheel.
