The invention discloses a high-low switching pair of intelligent street lamps, comprising a lamp post, a transverse rod slidably provided on the lamp post, a
rotating drum rotatably provided on the transverse rod, and a
brush provided on the inner wall of the
rotating drum. When the transverse rod is raised or lowered, the
rotating drum rotates and brushes the lamp post; a
water storage tank is fixedly provided on the transverse rod, a water sprinkling
pipe is fixedly provided on the
water storage tank, a plurality of through holes are provided on the rotating drum, the water outlet ends of the sprinkling pipes face the through holes, and water is sprayed onto the
brush through the through holes; the invention also includes an intermittent component, which is used to allow water in the
water storage tank to intermittently flow into the sprinkling
pipe. When the transverse rod is lowered, the rotating drum rotates to cause the
brush to scrub the lamp post, thereby facilitating cleaning of the top of the lamp post. At the same time, by arranging a
water storage tank on the transverse rod and cooperating with the
water storage tank with the intermittent component, the water in the
water storage tank intermittently flows out through the sprinkling
pipe and sprays on the brush through the through holes, thereby improving the scrubbing effect of the brush on the lamp post and also improving the cleaning efficiency of the lamp post.
