The utility model provides a robot and visualization system for the product oil tank cleaning, including automobile body, power unit, drive mechanism, motion, wiper mechanism and visualization system. Power unit adopts the pneumatic element, and is safer at the tank cleaning in -process. Drive mechanism and motion adoption crawler -type running gear have that to support the area big, and the little characteristics of ground contact pressure are suitable for the operation of soft or muddy place. The wiper mechanism has washing, a soil pick -up dual function, and the washing nozzle can the luffing motion moreover, adjustment (upper and lower angle of adjustment is - 15-75) of realizing shower nozzle spray angle to realize the washing of robot to the different angles of tank bottoms jar wall, the wiper mechanism still has a sewage suction pipe way backpurge system, when through traffic monitoring discovery robot through the back flush of jar outer pneumatic control system realization to the sewage suction pipe way when taking the dirt suction pump flow to descend. Locate to be equipped with visual monitoring system, visual real time monitoring robot motion state and position by washing jar manhole.
