Description

[0002] The cleaning devices of photovoltaic power plants mainly include photovoltaic power plant cleaning robots and photovoltaic module automatic cleaning devices. These devices are designed to improve the cleaning efficiency of photovoltaic modules, thereby improving power generation efficiency.

[0003] A common photovoltaic power station includes columns, inclined beams and photovoltaic modules. The photovoltaic panels of the photovoltaic modules are cleaned by cleaning sponges. Generally, a driving device is driven by a motor to move, and the driving device drives the cleaning sponge to move, so as to clean the dust on the surface of the photovoltaic panel.
