Description
Technical field
The utility model belongs to sea floor exploration field, ocean, the visual overlength gravity piston type sampling system of controlling of specifically a kind of deep water.
Background technology
At present, the main gravity piston sampling system of using has two types:
1. simple-type gravity core system.When on the ship during wirerope snap-out release, sampling system overcomes the buoyancy and the resistance of seawater under counterweight and deadweight effect, and the drag shoe of its lower end leans on kinetic energy injection stratum, and mouth of pipe pawl spring prevents that core from coming off carrying when boring; The ball valve on stopple coupon top is opened under the inner pipe water pressure effect when ST injection soil layer, and closes when mentioning, and avoids seawater scouring with the protection core; Stablize plumbness and improve falling speed in order to keep stopple coupon to be in, counterweight, stabilizator and the wire rope mechanism of dishing out generally also is set in the process of falling into; Because soil sample will overcome and the friction force of stopple coupon inwall and the hydraulic pressure in the stopple coupon when in stopple coupon, rising, the phenomenon that soil sample is compacted in when sample is longer, can occurring managing, thus changed sample length.
