▎ 摘　　要

NOVELTY - The utility model claims a solar graphene power supply device, comprising a box body, the inner cavity of the box body is fixedly connected with a transverse plate, the top part plate is embedded with a water permeable plate, the left side of the box body is fixedly connected with an electric telescopic rod through a supporting plate, the top part telescopic rod is fixedly connected with a longitudinal pipe through a support plate, the right side of the longitudinal pipe is connected with a nozzle, the bottom of the left side of the box body is connected with a water pump, the water outlet pipe of the water pump is connected with a telescopic hose. The utility model can adjust the inclined angle of the battery plate, the surface of the battery plate is washed, the solar light utilization rate is high, it solves the problem that the graphene solar power supply device battery plate is fixedly installed, it can not adjust the inclined angle of the battery plate, it can not wash the dust on the surface of the battery plate, so that the solar utilization rate is low, reducing the problem of graphene of the solar power supply device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the power supply device for graphene.
