Seabed volcanic rock sampling device for marine mineral exploration

Abstract

The invention discloses a seabed volcanic rock sampling device for marine mineral exploration. The sampling device comprises a sampling body, and connecting rings which are annularly distributed at equal intervals are welded on the outer wall of the top of the sampling body, and fixed blocks which are annularly distributed at equal intervals are welded on the outer wall of one side of the samplingbody; connecting lugs which are annularly distributed at equal intervals are welded at the edge of the outer wall of the bottom of the sampling body; circular through holes are formed in the outer walls of one sides of the connecting lugs, bending arms are inserted into the circular through holes, damping legs are welded to the outer walls of the bottoms of the bending arms, supporting legs are welded to the outer walls of the bottoms of the damping legs, antiskid lines are formed in the outer walls of the bottoms of the supporting legs, damping rods are arranged on the outer walls of the bottoms of the fixing blocks, and shaft sleeves are welded to the bottom ends of the damping rods. Marine organisms such as coral and sea grass around the surface layer of the sampling layer can be crushed and removed, and the situation that the sampling layer is broken in the sampling drilling process, the sampling layer is damaged, and the sampling result is affected can be prevented.

Description

technical field [0001] The invention relates to the technical field of seabed sampling, in particular to a seabed volcanic rock sampling device for marine mineral exploration. Background technique [0002] Volcanic activities can also form a variety of minerals. The basalt erupted by submarine volcanoes can often form large-scale iron ore and copper ore. Basalt is the most widely distributed volcanic rock, and it is also a good building material. The smelted basalt is called "cast stone". Exploration and sampling of volcanic rock masses is required during marine mineral exploration. [0003] After retrieval, the Chinese patent authorization number is CN106988696A, which discloses a carry-on deep-sea mineral resource core drilling rig, including a drilling rig frame, a core drilling tool, a power rotary system, a flushing and slag discharge system, a drilling lifting system and a mounting installation. Interface; the power rotary system is slidingly connected with the drill...
