UNDERWATER SONDE Russian patent published in 2009 - IPC G01S15/00 

FIELD: mining.

SUBSTANCE: underwater sonde includes container with information instrumentation comprising parametric antenna, sound detector with receiver antenna and sound velocity measurement sensor, computer-controlling equipment, electric power unit and buoyancy control device with actuator mounted in the lower part of container and consisting of two parts, wherein lower part includes inner section made of flexible material with walls of outer section perforated to communicate with water environment and upper part is filled with ballast compressing magnetic liquid and communicates with lower part by means of pipe with control valve, actuator being made as an electric motor. Container is bell-shaped wherein upper part has sensory ring with instrumentation sensors installed thereon and lower part is joined with gondola by means of rotation gear equipped with dovetailed telescopic slips. On one end side gondola is equipped with access ramp connected with adjustable bracket, whereon transmitting-receiving hydro-acoustic detectors are mounted, on the other end side gondola is equipped with end electric machine with disc inductors and monolithic disc rotor, wherein shaft has screw propeller installed. Lower part of gondola is made as keel, electric power unit is provided with electric micro-machine with constant magnets on rotor, antenna complex including hydro-acoustic detectors consists of 8-canal 2-section receiving hydro-acoustic antenna, each section of receiving antenna being 4-element non-equidistant hydrophone modular block. Sections of receiving antenna are located in horizontal plane perpendicularly to each other, navigation-controlling modular block and depth sounder are introduced additionally.

EFFECT: extended functional possibilities and independence of the device.
