Description
Technical Field
The invention relates to the technical field of ship rust removal, in particular to an intelligent ship rust removal robot and a using method thereof.
Background
After a ship sails in the ocean for a period of time, the surface of a hull shell is easy to rust due to electrochemical corrosion and marine organism corrosion, and even if isolated corrosion prevention and electrochemical corrosion prevention are adopted, the occurrence of the event cannot be completely prevented, so that the surface of the ship needs to be regularly derusted and cleaned. At present, the main hull surface rust removal methods can be divided into the following three categories: 1. derusting by an artificial ship; 2. chemical ship rust removal; 3. and (5) derusting the mechanical ship. The manual ship rust removal method has the longest application time and the widest application range. The manual ship rust removal takes manpower as main labor force, and the rust removal worker is provided with rust removal tools such as a hammer, a scraper knife, a scraper, a steel wire brush and the like. But the manual derusting efficiency is low and the derusting quality is poor. The chemical ship rust removal is a ship rust removal method which removes a rust layer on the surface of a ship by utilizing double decomposition reaction of acid and metal oxide to generate soluble metal ion salt. Compared with manual ship rust removal, the chemical rust removal has higher cost and higher requirement on the operation environment, and the chemical rust removal can be generally operated only in a workshop and is not suitable for dock operation. In addition, in the chemical rust removal process, the steel which is not corroded yet is also corroded by acid, and irreversible damage is easily caused to ships. And the wastewater generated by chemical rust removal belongs to hazardous waste, the treatment difficulty and the treatment cost of the hazardous waste are extremely high, the requirement of environmental protection is not met, and the sustainable development of enterprises is not facilitated. Compared with manual ship rust removal and chemical ship rust removal, the mechanical ship rust removal has the advantages of high efficiency and low cost.
The existing mechanical ship rust removal mainly comprises sand blasting rust removal and ultrahigh pressure water jet rust removal. Compressed air is used as power for sand blasting, spray materials are sprayed to the rusty ship surface at a high speed after high-speed spraying is formed, and a rust layer falls off from the ship surface under the high-speed impact of the spray materials, so that the aim of rust removal of the ship surface is fulfilled. The ultra-high pressure water jet rust removal is to use a high pressure water generation system to enable the water pressure to reach more than 1500bar, and then use the ultra-high kinetic energy of the high pressure water to enable a rust layer to fall off in the collision process with jet water. However, this method also has certain limitations; on one hand, the Young modulus of water is very small, so that the surface of the treated steel cannot reach high enough finish no matter how large the water pressure is, the chelation degree of secondary spraying is not good enough, and the coating is easy to peel, bubble and fall off; on the other hand, steel treated with high-pressure water is highly susceptible to flash rust, and flash rust treatment often relies on complex and expensive aqueous flash rust inhibitors. The use of the water-based flash rust inhibitor can increase the rust removal cost, and the water-based flash rust inhibitor can greatly reduce the adhesion between the subsequently coated oil paint and the surface of the ship.
By integrating the ship rust removal method and the rust removal difficulty, the development of the high-efficiency rust removal device which does not need to utilize water resources, can effectively reduce energy consumption, does not have dust pollution, does not need sewage treatment and has low labor cost is particularly important in the ship surface rust removal operation process.
