Abstract

The invention discloses a marine fixed auxiliary anode device. The marine fixed auxiliary anode device comprises an anode rod, an anode insulating seat, a conductive fastening rod and a wiring cabin. The anode rod is welded to the upper end of the conductive fastening rod, the welding position of the upper end of the conductive fastening rod and the anode rod is packaged in the anode insulating seat, the lower end of the conductive fastening rod is provided with threads, penetrates through the bottom of the anode insulating seat and penetrates through a ship body outer plate to enter the wiring cabin, the auxiliary anode is fixed through a fastening nut in the wiring cabin, a sealing ring in a groove in the bottom of the anode insulating seat is pressed and deformed to realize watertightness at the mounting position, the wiring cabin is sealed through a flange cover, and a wire protection tube is arranged on the side wall of the wiring cabin and is communicated with the wiring cabin. The anode cable passes through the wire protection tube, enters the wiring cabin and is fixed at the lower end of the conductive fastening rod through a bolt. The device is simple in structure; due to the design of multiple sealing materials, the device is good in overall sealing performance and high in corrosion resistance; and the device has the advantages of long service life and convenience in installation.

Description

technical field [0001] The invention relates to the field of impressed current cathodic protection, in particular to a marine fixed auxiliary anode device. Background technique [0002] Ships navigating in the harsh marine corrosion environment for a long time usually need cathodic protection to prevent corrosion damage. Among them, cathodic protection is divided into impressed current cathodic protection and sacrificial anode cathodic protection. Impressed current cathodic protection is more and more widely used in the corrosion control of oceangoing ships due to the advantages of large current generation, long service life, quick installation, low installation cost, and no potential marine biological pollution hazards. [0003] The existing auxiliary anode device for cathodic protection has a complex structure and poor sealing. When the auxiliary anode on the marine ship is working, ClO will be generated around it. - Such as ions with strong oxidizing properties, which w...
