Is different.
On the other hand, in the cleaning device shown in Patent Document 1, since the holding member can move in the lateral direction, it is possible to correspond to the photovoltaic power generation panel equipment having different lengths in the lateral direction.

However, since the cleaning body portion is fixed to the holding member, it has not been possible to cope with the photovoltaic power generation panel equipment having different vertical lengths.
Therefore, in order to support the photovoltaic power generation panel equipment having different vertical lengths, the vertical lengths of the holding member and the cleaning body portion should be set to the length corresponding to the vertical length of the photovoltaic power generation panel equipment. Need to form.
That is, it is necessary to manufacture a cleaning device for each photovoltaic power generation panel facility having a different vertical length, which is not economically preferable.

As a solution to this problem, Patent Document 2 discloses a cleaning device provided with a cleaning body (cleaning body portion) that moves in the horizontal direction and the vertical direction with respect to the photovoltaic power generation panel.
More specifically, with reference to FIG. 8, Patent Document 2 describes a moving frame 11 composed of a guide rail extending between the upper end and the lower end of the photovoltaic power generation panel P, and a guide rail of the moving frame 11. A cleaning device 10 for a photovoltaic power generation panel including a cleaning body (cleaning body portion) 12 for cleaning the photovoltaic power generation panel movably installed along the line is shown.

According to the photovoltaic power generation panel cleaning device 10 shown in Patent Document 2, the moving frame 11 moves laterally with respect to the photovoltaic power generation panel P with respect to the photovoltaic power generation panel P, and the cleaning body (cleaning body ( The entire panel surface can be cleaned by the cleaning body portion) 12 moving in the vertical direction along the moving frame 11.
Moreover, by changing the length of the moving frame 11 passed between the upper end and the lower end of the photovoltaic power generation panel P, it is possible to correspond to the photovoltaic power generation panel equipment having different vertical lengths, which is economical. Is preferable.
