Background
Cathodic protection technology is widely used in various aspects of production and life as an effective corrosion protection means. Generally, cathodic protection methods are mainly divided into two types: the impressed current cathodic protection and the sacrificial anodic protection, wherein the impressed current cathodic protection method is widely applied due to the characteristics of long service life, large current generation, small potential environmental pollution hidden trouble and the like. When the equipment pipelines and the like in some water bodies need to be subjected to impressed current cathodic protection, an auxiliary anode is usually fixedly arranged in the water bodies. When the water level changes, the auxiliary anode is exposed out of the surface of the water body, so that the protection range is limited, and protection current can be generated only at a fixed position, and incomplete protection of equipment pipelines and the like can be caused. Especially in places with larger water level drop in coastal areas, the fixed auxiliary anode often cannot function well, and unexpected corrosion is easily caused to equipment pipelines and the like.
