PURPOSE:To prevent leakage of a sample from a sampler, by loosening a rubber sleeve, and wrenching it to block up the lower end of a sampling tube after sampling by means of pressing force and torque of a spring. CONSTITUTION:A sample is drawn into the sampler tube 3' of an inner cylinder 3 dropped to the bottom of the sea or the like, and when a sink 24 is dropped in that state, a metallic hanger 8, etc. are released from the hole 7 of an outer cylinder 2 to raise a movable ring 11 through a chain 10, and engagement with the ring 11 is released to turn a stopper 14 to the outside. So, the inner cylinder 3 is disengaged and raised and turned by pressing force and torque of a spring 20, resulting in loosening the rubber sleeve 17 of the lower part of the inner cylinder 3 and wrenching it. Accordingly, the lower part of the inner cylinder 3 is blocked up to stop the leakage of the sample from the sampler, thus permitting good sampling. |
