Description
Technical Field
The utility model belongs to the technical field of cathodic protection, and particularly relates to a comprehensive monitoring protection device of an impressed current cathodic protection system.
Background
The impressed current cathodic protection system is widely applied to ocean engineering corrosion prevention, such as harbor wharfs, sea-crossing bridges, offshore platforms and the like. The impressed current system has a complex composition structure and comprises components such as a direct current power supply, an auxiliary anode, a reference electrode, a cable and the like. When the impressed current system is in service in the marine environment, the impressed current system is easily corroded, washed by sea waves and damaged mechanically, so that the corrosion damage or the function abnormality of components is caused, the impressed current system breaks down, and the impressed current system cannot run normally.
Impressed current systems are often manually inspected regularly to detect or address anomalies in a timely manner. However, different parts of the impressed current system are respectively arranged at different parts of the ocean engineering structure, certain parts (such as the bottom of a wharf and an offshore wind power foundation) are not easy to reach, time and labor are consumed for manual detection, the workload is large, continuous monitoring is difficult to realize, and failure early warning and untimely processing are easy to cause.
Part of the impressed current system has a monitoring function, but monitoring parameters of the impressed current system mainly comprise output current and output voltage of a direct current power supply or protection potential of a protected steel structure, and the monitoring function of the impressed current system is easily influenced by system faults, so that the overall operation condition of the impressed current system is difficult to reflect comprehensively and continuously, and timely and effective control is realized.
