Self-navigation full-automatic cleaning device for photovoltaic cell panel

The invention discloses a self-navigation full-automatic cleaning device for a photovoltaic cell panel. The device has the full-automatic functions of automatically navigating travelling, automatically regulating a cleaning state, automatically selecting a cleaning mode and automatically charging an accumulator. The load-bearing trolley of the device realizes the automatic travelling function of a fixed route by utilizing a self-navigation sensing system and detecting characteristic markers previously placed on site; the lifting platform, telescopic link, brush roller bracket and fixed bearing of the device can completely substitute for the design of a mechanical arm to realize the automatic real-time control of the angle height of the brush roller bracket and realize the function of automatically regulating the cleaning state according to pressure sensing data; a photoelectric sensing system can feed back the dust dirty degree of the surface of the photovoltaic cell panel in real time so as to regulate the travelling speed of the load-bearing trolley and the rotation speed of a brush roller and determine whether a water spray cleaning mode is adopted or not. The self-navigation full-automatic cleaning device disclosed by the invention is simple in structure, can not only save the cost, but also increase the cleaning efficiency, and is very suitable for large-area popularization and usage.
