Description
Technical Field
The utility model relates to the technical field of cathodic protection, in particular to a temporary cathodic protection system for offshore wind power.
Background
As the development and utilization of the ocean are increased, many metal devices such as ocean platforms, cross-sea bridge steel structures, harbor wharfs and the like are often arranged in the ocean area and around the ocean area; because seawater contains a large amount of corrosive salts, the metal equipment is easy to corrode, damage and even break risk in the corrosive environment for a long time, and the use effect and the use safety are affected. In order to protect these metal equipment, cathodic protection measures are often employed to protect marine metal structures from seawater corrosion.
The cathode protection technology is used as an effective means for corrosion prevention control and is widely applied to protection of important facilities and equipment such as ships, oil platforms, pipelines, bridge wharfs, offshore wind power and the like. Cathodic protection techniques are divided into sacrificial anodic protection techniques and impressed current protection techniques. Sacrificial anode protection is to connect a metal to be protected with another metal or alloy having a lower electrode potential so that the metal or alloy is preferentially consumed as an anode and the metal to be protected is protected by obtaining a cathodic current. The impressed current cathodic protection system generally consists of three parts, namely direct current, an auxiliary anode and a reference electrode, and an external direct current power supply and the auxiliary anode supply extra cathodic current to the protected metal structure, so that corrosion of the protected metal is inhibited. In the cathode polarization process, the polarization potential of the protected structure can be changed due to the change of external environment, such as the dissolved oxygen content, temperature, ocean current, salt content and other environmental parameters, and the dynamic balance of the polarization potential of the protected structure can be maintained only by adjusting the polarization output current in real time.
Compared with sacrificial anode cathodic protection, the impressed current cathodic protection system is suitable for various sea water working conditions, has stronger output regulation capability and small system load, can realize remote intelligent digital control, and is more suitable for cathodic protection of marine facilities and equipment.
At present, because an electric power facility is not completely built in the construction process of the offshore wind power foundation pile, and the operation condition of an impressed current cathodic protection system cannot be met, the impressed current cathodic protection device for offshore wind power is generally applied to corrosion control of steel members operated after the facility is built.
However, the construction of the offshore wind power foundation pile is affected by factors such as meteorological conditions, and the period is relatively long. During this time, steel components in a seawater environment are at risk of premature corrosion. In addition, the corrosion control cannot be performed by using an impressed current cathodic protection system installed in the facility itself under the influence of power supply factors, and in order to solve the problem, the problem can be solved by adding a sacrificial anode as temporary cathodic protection, but the investment budget of the facility can be greatly increased.
