ANODIC PROTECTION METHOD OF CHAIN AND ANODIC PROTECTION APPARATUS THEREFOR

摘要

PROBLEM TO BE SOLVED: To suppress corrosion by a simple mechanism and manipulation and to improve the life of a metallic chain by installing sacrificial anodes of the links of the chain to be at least partly immersed in the seawater or water. ;SOLUTION: The link 5 of the metallic chain 1 is held transversely in a central position by means of the sacrificial anode 2 consisting of two semi- elliptic spheres and is fixed by bolts and nuts penetrating both sides of the semi-elliptic spheres, by which the partial exchange of the sacrificial anode 2 is made possible. The sacrificial anode 2 of the semi-elliptic spheres is constituted to the form of covering about half to about 3/4 of the links 8 and 9 existing at both sides of the link 5. The flat surface side of the semi-elliptic spheres has holes or gaps 10 of a shape into which the link 5 at the center and the links 8 and 9 on both sides are fitted. The outer side of the semi-elliptic spheres has bolts 6 and bolt holes for nuts for fixing and countering notched parts 11' to allow the mounting of the sacrificial anode 2 at the links 5, 8 and 9.;COPYRIGHT: (C)2000,JPO
