MANHOLE COVER ANTICORROSION SYSTEM
PROBLEM TO BE SOLVED: To achieve a manhole cover anticorrosion system enabling proper cathodic protection depending on environmental conditions of manhole covers.SOLUTION: A manhole cover anticorrosion system includes: a cathodic protection power supply 21 which applies a voltage to a manhole cover and is capable of changing a potential level of the manhole cover by applying the voltage; an environment sensor 22 which detects the environment inside the manhole which corrodes the manhole cover; and a control circuit 23 which controls the cathodic protection power supply such that the potential of the manhole cover comes to a potential level for preventing corrosion according to the environment inside the manhole detected by the environment sensor.SELECTED DRAWING: Figure 1
【課題】マンホール蓋が置かれた環境状況に応じた適切なカソード防食を可能にしたマンホール蓋防食システムの実現。【解決手段】マンホール蓋に電圧を印加し、電圧印加によるマンホール蓋の電位レベルを変更可能であるカソード防食用電源21と、マンホール蓋を腐食させるマンホール内の環境を検出する環境センサ22と、マンホール蓋の電位が、環境センサが検出したマンホール内の環境に応じた腐食を防止する電位レベルになるように、カソード防食用電源を制御する制御回路23と、を有するマンホール蓋防食システム。【選択図】図１
