APPARATUS FOR GENERATING SEISMIC WAVES IN WATER MEDIUM Russian patent published in 2016 - IPC G01V1/155 G01V1/38 

FIELD: physics.

SUBSTANCE: operation of the disclosed device is based on using repulsive forces arising in an impulse force exciting source placed in a sealed housing and moving in the investigated medium in the form of pressure pulses, while exciting elastic vibrations in the required direction in said medium. The value of the pressure pulses and the direction of propagation of the elastic vibrations is provided due to that the corresponding shape of the sealed housing enables to use the surrounding water medium as a supporting surface which generates resistance to the movement of the sealed housing towards the surface of the water medium. The apparatus comprises a floating means, a sealed housing in which an actuating pulse source is placed and a windlass. The sealed housing is made of two parts, capable of relative movement along the vertical axis in opposite sides, and the upper surface of the housing has a much larger area than the lower surface.

EFFECT: high quality of the obtained information.
