SLIDE CORE RETAINER PROVIDED ON SAMPLER

摘要

The present invention relates to a slide core retainer provided on a sampler comprising a sample pipe which is inserted into the sea bottom through a drive unit. The slide core retainer comprises: a catcher holder which is detach ably coupled to the front end of the sample pipe; a catcher which is installed in the inner circumference surface of the front end of the catcher holder, and allows the flow of sediment into the sample pipe by elasticity and prevents the loss of the inflow sediment; and an open / shut control member which is slide ably provided on the catcher holder to control the opening and shutting of the catcher, wherein the open / shut control member is coupled to the catcher to force the catcher to be opened before a sample is sampled, and is separated from the catcher by resistance due to deep sea sediment and is slid into the catcher holder after the sediment is inserted into the sample pipe and generates resistance due to the deep sea sediment, thereby closing the catcher.
