the method comprises the following steps: the shielding cloth (3-1) and the cleaning subsystem (3-2) are all bent into a roll and are stored in the rotating shaft (3-3), and the upper edge of the shielding cloth (3-1) is positioned at the lower edge of the photovoltaic module (1-1) of the power generation element; controlling an energy storage battery (4-1) to supply positive electricity to a lifting stretching motor (3-4-1) so that the roller (2-3) moves upwards to drive the upper edge of the shielding cloth (3-1) to move upwards; meanwhile, the energy storage battery (4-1) supplies positive power to the rotating shaft motor (3-4-2), so that the rotating shaft (3-3) rotates positively, the shielding cloth (3-1) wound on the rotating shaft (3-3) is gradually turned outwards, the upper edge of the shielding cloth (3-1) reaches the upper edge of the metal frame (1-2), at the moment, the energy storage battery (4-1) stops all power supply, the lifting stretching motor (3-4-1) and the rotating shaft motor (3-4-2) stop working, the shielding cloth (3-1) is completely opened and is paved above the power generation element photovoltaic module (1-1);
step two: rain and snow left on the surface of the shielding cloth (3-1) are melted into water, the water flows into the melted water source accommodating groove (2-4) along the inclined plane, the energy storage battery (4-1) is controlled to supply reverse power to the lifting stretching motor (3-4-1), and the roller (2-3) moves downwards to drive the shielding cloth (3-1) to move downwards along the upper edge; meanwhile, the energy storage battery (4-1) supplies reverse power to the rotating shaft motor (3-4-2) to enable the rotating shaft (3-3) to rotate reversely, the shielding cloth (3-1) is wound on the rotating shaft (3-3), and the shielding cloth (3-1) and the cleaning subsystem (3-2) are completely bent into a roll and are wound on the rotating shaft (3-3) and then stop; the brush of the cleaning subsystem (3-2) and the polyvinyl alcohol rubber surface are all bent into a coil and stored in the rotating shaft (3-3) and soaked in the rain and snow melt water; during cleaning, the energy storage battery (4-1) is controlled to provide forward electricity for the lifting stretching motor (3-4-1) and the rotating shaft motor (3-4-2), the rotating shaft (3-3) is driven to rotate forward and the pulling roller (2-3) moves upwards at the same time, the shielding cloth (3-1) moves upwards, when the upper edge of the power generation element photovoltaic module (1-1) is to be reached, the energy storage battery (4-1) is controlled to provide reverse electricity for the lifting stretching motor (3-4-1) and the rotating shaft motor (3-4-2), the rotating shaft (3-3) is driven to rotate reversely and the pulling roller (2-3) moves downwards, and the shielding cloth (3-1) moves downwards; repeating the process, controlling the cleaning subsystem (3-2) to reciprocate up and down, and cleaning the photovoltaic assembly (1-1) of the power generation element;
step three: after cleaning is finished, the energy storage battery (4-1) is controlled to supply reverse power to the lifting stretching motor (3-4-1) and the rotating shaft motor (3-4-2), so that the shielding cloth (3-1) and the cleaning subsystem (3-2) are completely bent to be coiled and stored on the rotating shaft (3-3).
