SEMI-AUTONOMOUS INSPECTION DEVICE OF SMALL-DIAMETER TUBULATIONS AND SEMI-AUTONOMOUS INSPECTION SYSTEM OF SMALL-DIAMETER TUBULATIONS EMPLOYING SAID DEVICE

摘要

The semi-autonomous inspection device being formed by a cylindrical body (1), having rear plate springs (3), with rollers (4) at their free ends, which centralize the cylindrical body Inside the tubulation (T), also having in the upper front part of the said cylindrical body a transducer (5), which projects outwardly, for contacting the inner wall of the tubulation, assisted by the supply of coupling fluid, powered directly by the conduit (6), and said transducer can be rotated by way of the rotary engine (7), also having an electronic circuit (8), developed especially for long distance Inspections, and the system being formed by a control unit (9), which is responsible for sending commands to the power controllers (10) which drive the engines (11), as well as controlling the electric drive of the pump (12).
