IN-SITU SLUDGE EXTRACTOR FROM BOTTOM SEDIMENTS Russian patent published in 2020 - IPC G01N1/16 

FIELD: physics.

SUBSTANCE: invention relates to ocean research, to investigation and analysis of bottom sediments. Sampler for separation of sludge water from bottom sediments in situ, consisting of pipe, top of which is connected with ship winch, and fixed set of loads, and bottom is equipped with lance weighted tip with stiffeners, characterized in that pipe is a set of cylindrical sections with holes for water supply, each section is equipped with lower and upper rings, between which there are movable clutches with spokes; groups of sections are connected by threaded couplings; in connection points of sections there are internal couplings with partitions dividing sections, inside each section there is a cup resting on internal coupling partition, and closed by a check valve, on the bottom of the sleeve there is a support ring with a plate on which there is a sludge water vessel covered with a filter; pipe surface in working places of movable coupling is coated with thin film which filters water.

EFFECT: technical result is possibility of sampling sludge water from bottom sediments.
