The invention relates to the technical field of intelligent traffic, and discloses a device for intelligent automatic control of cleaning of a hydraulic supporting rod. The device comprises a closed disc, the interior of the closed disc is movably connected with a movable sliding block and a reset spring, the lower part of the closed disc is movably connected with a pollution discharge track, theinterior of the pollution discharge track is movably connected with a pollution control sliding block, the right side of the closed disc is movably connected with a transmission wheel, the upper partof a transmission wheel valve is movably connected with a cleaning wheel, and the left side of the cleaning wheel is movably connected with a supporting base. The cleaning wheel is controlled to startrotating to drive the movable sliding block to rightwards move, the movable sliding block resets under the elasticity effect of a movable spring, meanwhile, the lower part of the movable sliding block is movably connected with a pollution removal brush, dust and the like on the outer side of the hydraulic rod is removed through motion of the pollution removal brush, thus the effect of cleaning the outer side of the hydraulic rod is achieved, and the working efficiency is improved.
