Flashboards are arranged at positions of a water intake, a water outlet and the like of the power plant to ensure that the power plant can be isolated from seawater when necessary. The gate plate guide groove is usually protected by a cathode protection system because the gate plate guide groove is in a harsher corrosion environment for a long time. Wherein the guide groove of the flashboard of the water outlet adopts the mode of impressed current cathodic protection.
This creates difficulties in the installation of auxiliary anodes in cathodic protection systems due to the large discharge capacity of the discharge port, turbulence and violent impact. In the related art, a steel pipe is adopted to install and fix the auxiliary anode, however, after the auxiliary anode is used, the steel pipe is seriously corroded due to the severe corrosion environment, and finally the auxiliary anode is broken under the action of water flow impact due to the reduction of strength. The PVC pipe with excellent corrosion resistance is used for installation, but the strength is often not enough, and the PVC pipe can be broken by water flow after installation. The auxiliary anode of the water outlet needs to be frequently reinstalled or maintained by maintenance personnel, so that cost is increased, the water outlet is poor in working condition, high in operation risk and high in potential safety hazard in frequent operation.
