Abstract
Provided is an apparatus for collecting marine deposits. The apparatus includes: a piston corer for collecting a deep part of marine deposits; a corer for collecting a surface part of marine deposits; and a trigger body connecting the corer for collecting a surface part of marine deposits and the piston corer for collecting a deep part of marine deposits to each other while being maintained at a laterally set interval. The apparatus for collecting marine deposits can greatly save costs consumed to collect marine deposits and increase accuracy of collecting the marine deposits.
Claims7
An apparatus for collecting marine deposits, comprising:
- a piston corer (10) for collecting a deep part of marine deposits, the piston corer having an external body (11) stuck in the deep part of a sea bottom while serving as a cylinder body and having a piston body (12) positioned in the external body (11) to move up and down and serving as a piston;
- a corer (20) for collecting a surface part of marine deposits, the corer including a deposits inserting pipe (21) in a pipe shape stuck in the surface part of the sea bottom and extending downwardly from a frame (22), the corer further including an upper cover (23) and a lower cover (24) blocking upper and lower portions of the deposits inserting pipe (21) when the deposits inserting pipe (21) is stuck in the sea bottom and in contact with the sea bottom before the piston corer (10) while having a weight guiding the falling of the piston corer (10);
- and
- a trigger body (30) connecting the corer (20) and the piston corer (10) to each other while being maintained at a laterally set interval and when the corer (20) is safely seated at the sea bottom, free-falling the piston corer (10) to be stuck in the deep part of the sea bottom while a rope (32) connected to the piston corer (10) is instantly untied.
