STATIONARY MEASURING SONAR COMPLEX Russian patent published in 2001 - IPC

FIELD: hydroacoustics; hydroacoustic search in deep water of seas and oceans. SUBSTANCE: proposed complex includes carrier for measuring equipment n form of buoy possessing positive buoyancy and buoy hoist-and-lower gear; drum of winch of hoist-and-lower gear is immovable. Drive is secured inside drum; rocker arm oriented horizontal is fitted on axle of drive; bearing roller is secured on one end of rocker arm and shackle is secured on other end; shackle is provided with roller for laying flexible cable which is fitted on horizontal axle. During rotation of drive, flexible cable is wound on/off drum, thus making the positive buoyancy buoy secured at end of flexible cable move up and down in natural basin. EFFECT: simplified construction of hoist-and-lower gear; enhanced operational reliability of hoist-and-lower gear. 8 cl, 3 dwg
