Technical Field
[0001] The utility model relates to the technical field of ship rust removal, in particular to an ultra-high pressure water rust removal multi-gun head device. 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, it is difficult for many shipyards to completely remove rust during the rust removal process, especially for the T-profile structural surface of the cargo hold, and the anti-corrosion effect is poor, which affects the service life of the ship. Due to the small space of the cargo hold T-profile and the inconvenient operation, workers are often required to hold the gun sideways to remove rust, which is inefficient and poses a safety hazard. Therefore, the ultra-high pressure water rust removal in the cargo hold T-profile area in the prior art has the following main disadvantages and shortcomings: low rust removal efficiency and waste of cost; poor rust removal effect and inability to completely remove paint rust; dangerous operation and potential safety hazards.
