When the sand on the photovoltaic panel 3 cannot be completely cleaned, the temperature of the photovoltaic panel 3 rises rapidly due to the heat absorption of the sand, thereby increasing the temperature of the expansion airbag 91 and expanding it, thereby causing the expansion airbag 91 to expand and drive the push plate 92 to move toward the back of the casing 1, thereby causing the push plate 92 to drive the sleeve 94 fixedly installed at the end of the bent rod 93 to move toward the inside of the casing 1, and then through the limit gear The engagement between 98 and the latching tooth 99 enables the sleeve 94 to drive the horizontal plate 910 fixedly installed at the end of the adjusting rod 96 to squeeze the brush handle 74, thereby making the brush handle 74 fit tightly against the outer wall of the photovoltaic panel 3, so that the brush handle 74 can better clean the photovoltaic panel 3. At the same time, the limiting tooth 98 is driven by the adjusting rod 96 to rotate and the limit between the latching tooth 99 is released, and then the horizontal plate 910 can be driven by the adjusting rod 96 to adjust its position, so that the brush handle 74 can better clean the photovoltaic panel 3.
