Generally, cathodic protection methods are largely divided into two categories: impressed current cathodic protection and sacrificial anodic protection, wherein the impressed current cathodic protection method is widely applied due to the characteristics of long service life, large generated current, small potential environmental pollution hidden danger and the like. When the equipment pipeline and the like in some water bodies need to be subjected to impressed current cathodic protection, the auxiliary anode is usually fixedly arranged in the water body. 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 only a fixed position can generate protection current, and the protection of equipment pipelines and the like is incomplete. Especially, in some places with large water level fall such as coastal areas, the fixed auxiliary anode often cannot function well, and the unexpected corrosion of equipment pipelines and the like is easily caused.
