Abstract

The utility discloses a deepsea hardrock core sampler. A core storage device is arranged on the upper of a penetrating drilling power unit. A core storage pipe in the core storage device is thoroughly connected with the upper end of a core inner pipe under the opening condition of a high pressure valve. The core storage pipe is provided with an attemperator and communicated with an outlaid pressurizer by a high-pressure pipe. A bit sealing baseplate is positioned at the underside of the drill bit. A core release ejector is vertically arranged at the center of the baseplate. The sealing baseplate is provided with a transfer actuating unit at the bottom. When the sealing baseplate and the core release ejector are shifted to the right inferior of the drill bit, the core is pushed into the core inner pipe from the core clamping spring by the ejector, and the drill bit is sealed with the sealing baseplate. The hydraulic water communicated with a water pump flows out upwards and transmits the core into the core storage pipe. The conservation of the core under the almost uniform temperature and pressure conditions with the former seabed can be fulfilled to make the analysis and test data of the core and the attached biological and chemical element more precise.
