FIELD: chemistry.SUBSTANCE: invention relates to sampling equipment. Plant for drilling from an underwater vehicle includes cantilever frame with guide bars, movable spring-loaded rotator with output shaft, moving crossbar and core tube with drilling bit. Cylinder feeding force onto axis of drilling is set parallel to axis of drilling and connected to a stationary bracket on one hand, and on other - with a bracket moving crosspiece with biased against it by springs rotator provided with a pump for flushing the drill bit configured to suction water from environment and further pumping it into well through the core barrel, set in lunette.EFFECT: improved quality of samples.1 cl, 8 dwg |
