Abstract

The invention relates to the technical field of submarine geological prospecting equipment and in particular relates to an undersea mechanical myriametre level light impact geological sampling device which comprises a main supporting frame, a guide sampling mechanism, a grounding releasing mechanism and a load rejection counterweight mechanism. The main supporting frame comprises a connecting disc in the bottom. A floating block is arranged on the connecting disc. The undersea mechanical myriametre level light impact geological sampling device provided by the invention is designed modularly, is conveniently produced in batches and maintained, is low in production cost, simple to mount, efficient and safe and reliable, and solves the technical problems that in the prior art, a deep undersea sampling device is complex in structure, low in efficiency, high in cost, hard to operate and maintain and the like.

Description

technical field [0001] The invention relates to the technical field of marine geological exploration equipment, in particular to a seabed mechanical 10,000-meter-level light impact geological sampling device. Background technique [0002] The ocean accounts for 70.78% of the earth's total area, and the depths of the ocean are widely covered with a layer of mysterious but very research-worthy seabed sediments. Seabed sediments are useful for understanding the changes in the earth's environment, revealing the inner connection between the earth's environmental systems and predicting the future. Long-term climate change is of great significance. Sampling and conducting in-depth research on seabed sediments can enable human beings to obtain very important scientific values ​​in the fields of marine scientific research, marine environment research, marine resource exploration, marine engineering exploration, etc. It is of great importance for human beings to understand the earth a...
