Title:
SOLAR PANEL CLEANING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/060009
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a solar panel cleaning device capable of cleaning the entire light-receiving surface of a solar panel system in which gaps are formed between panel units. The solar panel cleaning device (1) is provided with: a body (2); a self-propelling means (3) for self-propelling the body (2) on a light-receiving surface (R) in a specified direction of movement (F); a cleaning means (4) for cleaning the light-receiving surface (R); a first sensor (7) and a second sensor (8) that are disposed in regions forward of the center of gravity (G) of the device (1) in the movement direction (F) of the body (2) and are capable of detecting the presence of a panel unit (P); and a control unit (5) for controlling the movement of the body (2) by the self-propelling means (3) on the basis of sensing information from the first sensor (7) and the second sensor (8). The first sensor (7) is disposed in front of the second sensor (8) and the separation distance between the first sensing position (71) of the first sensor (7) and the second sensing position (81) of the second sensor (8) is set to be greater than the gaps (S).
