PISTON CORE TYPE WATER SAMPLER COMBINED BOTTOM SAMPLER

摘要

The present invention relates to a piston core type bottom sampler combined with a water sampler capable of collecting water with precipitates, such as mud, sand, and others under the water and, more specifically, to a piston core type bottom sampler combined with a water sampler capable of increasing precipitate and water collection efficiency and water sampling efficiency, being safely pulled after collection, and safely performing water sampling by maintaining watertightness during the collection. The piston core type bottom sampler combined with a water sampler comprises a weight part and a bottom sampling part. The weight part adjusts the weight by laminating weights, and has a first wire fastened in a hook at the top of a pillar pipe. A head having a vertically penetrated bottom sampling hole is assembled to the front end of a bottom sampling induction pipe assembled to the bottom of the pillar pipe of the weight part. The bottom sampling part has a check valve positioned between the pillar pipe and the head toward the pillar pipe, and a bottom sampling pipe having both ends being in contact with the check valve and the head. The piston core type bottom sampler combined with a water sampler comprises a ball valve installed in the middle of the bottom sampling hole of the head, and having a lever exposed to the outside of the head; and a second wire having the bottom fastened to the lever, and used when the ball valve is turned off and the bottom sampler combined with the water sampler is pulled. The second wire is entered into the pillar pipe through a wire guiding hole formed on the pillar pipe and is fixed on a latch positioned in the hook while being exposed to the upper part of the pillar pipe. The top of the second wire is fixed on a winder installed in a ship.
