Electrochemical corrosion principle based steel structure equipment

Abstract

The invention relates to the technical field of steel structure corrosion prevention in seawater, and discloses electrochemical corrosion principle based steel structure equipment. The electrochemicalcorrosion principle based steel structure equipment comprises a cover body, wherein the two side walls inside the cover body are fixedly connected to displacement slots; elastic rods are movably connected inside the displacement slots; the other ends of the elastic rods are movably connected to rollers; waterproof ropes are wound on the surfaces of the rollers; the other ends of the waterproof ropes are movably connected to wrapping posts; the lower ends of the wrapping posts are movably connected to telescopic poles; the surfaces of the telescopic poles are movably connected to springs; andthe other ends of the springs are movably connected to rust-removal wheels. While seawater rises, the cover body is pushed to move upwards, the cover body slides on the surface of a steel component, and an arc-shaped knife upwards moves in the vertical direction and also moves in the horizontal direction under influences of liquidity of seawater, so that impurities and rust on the surface of a contact position of the steel component and the arc-shaped knife are removed, and therefore, the automatic rust-removal effect is achieved through sea wave fluctuation motion.

[0002] Steel structure is a structure composed of steel materials. It is one of the main types of building structures. It is light in weight and easy to construct. It is widely used in large factories, venues, super high-rises and other fields. With the development of my country's ocean engineering , some bridges or marine equipment also use steel structures, but steel structures contain a lot of carbon and iron, and are easily corroded when soaked in seawater for a long time. The existing technology uses sacrificial anode cathodic protection to slow down the corrosion rate of steel structures

[0003] Although this method is relatively mature, due to the large size of the steel structure, the traditional cathodic protection method can only protect a certain section of the steel component. If you want to protect the entire steel structure, you need a large number of zinc columns, which wastes materials and increases the number of cathodes. Difficulty in implementing the protection method; in addition, the steel structure has been soaked in seawater for a long time, and corrosive substances will adhere to the surface, which will accelerate the corrosion of steel components. However, the existing technology can only use artificial diving to clean it without corresponding treatment. Equipment, so a steel structure equipment based on the principle of electrochemical corrosion came into being
