Description

Technical Field

[0001] The utility model relates to the technical field of rust removal in a dock pier area at the bottom of a ship, and in particular to a spray disc actuator and a rust removal robot. Background Art

[0002] After various ships and drilling platforms have been used at sea for a period of time, a thick layer of marine organisms will be attached to the hull, and the hull plate will also be corroded by seawater. The hull plate will slowly rust, and the corrosion will become more serious over time. Therefore, ships and drilling platforms must be returned to the factory for rust removal and paint maintenance after a period of operation to avoid serious corrosion.

[0003] At present, many shipyards have changed from traditional sandblasting to ultra-high pressure water rust removal, using high pressure water to directly wash away marine organisms and rusted parts on the hull. With the popularization and application of rust removal equipment, manual work has gradually developed into mechanization, and automatic rust removal robots have emerged. Existing automatic rust removal robots are generally equipped with a spray plate with a water outlet, and the high pressure water at the outlet is used to wash away marine organisms and rusted parts on the hull.

[0004] However, the existing spray discs only consider the cleaning function, that is, they only consider how to wash away the marine organisms and rusted parts on the hull, but do not consider the recovery of impurities. The washed impurities are allowed to be scattered directly on the ground, which not only causes a waste of water resources, but also requires the subsequent collection and cleaning of the impurities on the ground, increasing labor costs.

The spray disc 13 flips along the second rotating shaft 121 on both sides. Since the second bracket 12 is provided with a limit baffle, the spray disc 13 can only flip in one direction, that is, flip in the direction away from the second bracket 12. By rotating the first bracket 11, the second bracket 12 and the spray disc 13, the position of the receiving groove 132 of the spray disc 13 is adjusted to facilitate fitting to the outer wall of the hull.

The ultra-high pressure water jet is generated and acts on the hull through the nozzle 134, and the hull surface corresponding to the rotating area of ​​the nozzle 134 can be effectively cleaned, thereby achieving high efficiency of the hull surface. A circle of brush bristles 135 is arranged around the top of the spray disc 13. When the spray disc 13 moves in contact with the outer wall of the hull, the outer wall of the hull can be brushed, which facilitates the cleaning of the outer wall of the hull.

[0038] Furthermore, the spray disc actuator 10 also includes a protective ring 14, which is arranged around the spray disc 13. The outer diameter of the protective ring 14 is larger than the outer diameter of the spray disc 13, and the inner diameter of the protective ring 14 is smaller than the inner diameter of the second bracket 12. By providing the protective ring 14, the spray disc 13 can be protected to a certain extent and effectively prevented from being damaged by collision.
