It is provided with glass cover and on plexiglass base plate for placing the active metal draw-in groove of active metal device.
It is additionally provided with the plexiglass tent for by the gas displacement hole of vacuum sealed box evacuation；Organic glass
It is provided with glass cover and on plexiglass base plate for the wiring hole through wire.
The edge for stretching out of the plexiglass tent bottom and sealing rubber pad is provided between plexiglass base plate.
Operation principle：The material for selecting activity stronger is as anode, electric when occurring in loop of the active material with steel strand wires
During son disappearance, electronics will be moved to from active material on the steel strand wires (or parallel steel wire) of drag-line so as to cathodic polarization occurs, reaches
To the purpose for reducing or completely inhibiting corrosion.Protection system is made up of adnexaes such as anode, connection cable and stayed structures.The negative electrode
Protection system can be from zinc bar isoreactivity metal material as anode.And carried out according to the concrete oxidization condition of active metal rod
Periodic replacement.
Beneficial effects of the present invention：
The stayed structure with anti-corrosion function of the present invention has advantages below：(1) stayed structure can be protected to prevent which
Generation electrochemical corrosion.(2) active metal rod is located in the seal box of lucite, is easy to check sealing situation and active metal
The corrosion condition of rod.(3) drag-line protection structure simple structure, is convenient for changing.
