DEVICE FOR METAL STRUCTURES ELECTROCHEMICAL PROTECTION AGAINST CORROSION Russian patent published in 1994 - IPC

FIELD: automobile transport, etc. SUBSTANCE: device for metal structures electrochemical protection against corrosion has a projector, mounted on metal structure in a fixed to the metal structure perforated casing, that embraces the projector with a clearance, and activator, made as at least one solid body of textolite and located in the clearance with capability to move. Casing is made vibrating and activator has abrasive powder in amount of 25.0 - 98 % mass of activator. Device may also have air feeding chamber, mounted on lower side of perforated part of casing; gas distributing lattice, placed on perforated part of casing and connecting the casing with the air feeding chamber; an air pulser with a servomechanism, connected bu a pipeline with the air feeding chamber. Besides, device may have a metal corrosion control sensor, mounted on the air feeding chamber and having electric connection with the servomechanism. In the case vibration source may be made of as an generator of sound oscillations and connected through elastic members with the casing and by electric connection - with the metal structure corrosion control sensor and the servomechanism. EFFECT: protection against metal structures corrosion. 4 cl, 1 dwg
