The invention discloses a
radar level meter automatic cleaning device which comprises a
radar device body, the bottom of the
radar device body is connected with a fixing plate, the bottom of the fixing plate is connected with a horn probe, and the radar level meter is protected through a telescopic cylindrical structure formed by a containing sleeve and a lifting sleeve. A heat insulation material can be laid on the inner wall of the lifting sleeve, the influence of
temperature difference is reduced as much as possible, a
servo motor is utilized to drive a lead screw to lift the lifting sleeve during use, a driving gear drives a driven gear ring to rotate at the moment, and a
silica gel scraping strip and a
sponge strip can be attached to the inner wall and the outer wall of a horn probe to rotate; dews on the inner wall and the outer wall of the horn probe are scraped and cleaned through the
silica gel scraping strip, the inner wall and the outer wall of the horn probe can be wiped through the
sponge strip following the
silica gel scraping strip,
liquid drop residues are avoided, and therefore the dews on the inner wall and the outer wall of the horn probe can be cleaned in advance in the using process, and the detection precision of the device is further improved. And great convenience is provided for production work.
