The invention relates to the technical field of
photovoltaic power generation, and discloses a device capable of changing the placement angle of a
solar cell panel and performing cleaning and cooling.The device comprises a cooling and cleaning device main body, a sliding groove is formed in the inner wall of the cooling and cleaning device main body, a sliding block is slidably connected to the interior of the sliding groove, and a spring is fixedly mounted at the bottom of the sliding groove. And a movable rod is movably connected to the right side of the sliding block, a rotating wheel is movably installed at the bottom of the movable rod, and a monopole
magnet is fixedly installed on the right side of the rotating wheel. A solution in the reservoir is evaporated through
irradiation oflight and enters the air bag, the weight of the reservoir is reduced, the rotating force of the rotating wheel is limited to be reduced, the single-pole
magnet on the rotating wheel can be attracted by the other single-pole
magnet, the rotating wheel rotates to jack up the sliding block, and the
solar cell panel ascends. And when the
light intensity of the left side is strong, the rising height ofthe left side is increased, and the effect of changing the angle of the
solar cell panel according to different illumination intensities is achieved.
