UNDERWATER VIDEO-ARM Russian patent published in 2008 - IPC B63G8/38 G01S3/80 

FIELD: physics.

SUBSTANCE: invention concerns television systems for underwater inspection. The arm contains underwater research equipment with photographic and video equipment mounted thereon, connected to picture monitor on control panel and supplied with electrically driven lifting gear. The arm is provided with flat arrow-shaped steel wing front-located with three vertical stabilisers serving as construction supporting foot. The wing is cable-towed through lifting gear by water vehicle. Transmitter of surveying echosounder is placed with direction response pattern on the bottom side vertically coaxial with the receiver of satellite grid station. Emitting sector contains control unit, electric motor case with headed screw and two bars fixing provisional weight attached to wing. Two guides between bars are furnished with sealed boxes and underwater lamps provided on both sides. View areas of photographic and video equipment established in sealed boxes are mutually crossed within surveyed surface. The whole view area of photographic and video equipment is overlapped with illumination sectors and two acoustic signal transmitters detecting wing plane position relative to surveyed surface. Real-time control, management and data transfer is performed through multicore cable connecting control unit, picture monitor and operator's stand.

EFFECT: high-quality panoramic close up surveying in poor visibility.
