A three-degree-of-freedom high-bearing working device of an underwater wall surface cleaning robot comprises water conveying pipes, a water gun, a rack, arm rods, a driving chain and linear drivers. The water conveying pipes are rigid pipes and comprise first, second and third water conveying pipes; the arm rods comprise a first arm rod, a second arm rod and a third arm rod; one end of each linear driver is mounted on the rack, and the linear drivers comprise a first linear driver and a second linear driver; the water conveying pipes are fixedly mounted on the arm rods; the rack, the arm rods, the driving chain and the linear drivers form a planar two-degree-of-freedom connecting rod mechanism which comprises a first closed loop, a second closed loop, a third closed loop and a fourth closed loop, and the inclination angle, the pose and the like of the water gun can be controlled; and the water conveying pipes communicate with one another through hoses, one end of the first water conveying pipe communicates with the high-pressure water way through a hose, and the third water conveying pipe communicates with the water gun. According to the cleaning working device of the wall surface cleaning robot, the three-degree-of-freedom controllable movement of the water gun relative to the rack can be realized, and the cleaning operation of outer vertical surfaces of marine equipment such as ships with large area and high structural complexity is realized by utilizing high-pressure water flow.
