Abstract

The invention relates to an offshore exploration mechanical device, in particular to a carrying type deep sea core drilling machine which can be carried on a manned submersible vehicle or an underwater robot to obtain deep sea rock and ore samples. The carrying type deep sea core drilling machine comprises a drilling machine main shaft, a bearing pedestal, a drilling tool, a hydraulic motor and a linkage base. The drilling machine main shaft is installed on the bearing pedestal. One end of the drilling machine main shaft is connected with the drilling tool, and the other end of the drilling machine main shaft is connected with an output shaft of the hydraulic motor. The hydraulic motor is installed in the linkage base. One end of the linkage base is fixed to the bearing pedestal, and the other end of the linkage base is fixed to a mechanical arm of the manned submersible vehicle or the underwater robot. A pressure compensation device is arranged on the bearing pedestal. The carrying type deep sea core drilling machine has the advantages of being compact in structure, light in weight, high in reliability and safety and the like; the various requirements under severe working conditions of deep sea core sampling can be met, the samples can be conveniently and reliably provided for the scientific research on deep sea ore resources, and the carrying type deep sea core drilling machine is suitable for underwater core drilling.

Description

technical field [0001] The invention relates to marine exploration mechanical equipment, in particular to a deep-sea core drilling machine for obtaining deep-sea cobalt-rich crusts and polymetallic sulfide cores. Background technique [0002] The vast ocean floor is rich in mineral resources, including cobalt-rich crusts, hydrothermal sulfide ores, etc., which have huge economic value and strategic significance. The deep sea is one of the few unknown regions on earth. Scientists are interested in deep sea mineral composition, mineral age, mineral formation mechanism, mineral physical and mechanical properties, and the biological and environmental conditions around minerals. These studies covering multiple disciplines of marine geology, marine biology, marine chemistry, marine physics, and marine mining require a large number of deep-sea mineral samples. At the same time, a large amount of exploration and core drilling work must be carried out in the evaluation of reserves o...
