Electric sampler for marine engineering geological detection and sampling method thereof

Abstract

The invention discloses an electric sampler for marine engineering geological detection and a sampling method thereof. The electric sampler comprises a partition board, wherein a first box body is fixedly arranged on the partition board; a second box body is fixedly arranged below the partition board; three third box bodies are fixedly arranged on the periphery of the second box body; a first hydraulic rod is fixedly arranged on the inner wall of each third box body; a bearing is fixedly arranged at the output end of each first hydraulic rod; a connecting piece is fixedly arranged below each bearing; a square rod is fixedly arranged on one side, away from the bearing, of each connecting piece; each square rod penetrates through the corresponding third box body, and a drill bit is fixedly arranged at one end, located outside each third box body, of the corresponding square rod; and a first belt wheel is arranged at the part, located in the corresponding third box body in a sleeved mode,of each square rod. The electric sampler is of the beneficial effects that the probability of manual launching is reduced, the safety of related personnel is guaranteed to a great extent, a columnarsample can be effectively taken out through vertical sampling, and the accuracy and the diversity of sampling are ensured.

Description

technical field [0001] The invention relates to the field of marine geological sampling, in particular to an electric sampler for marine engineering geological detection and a sampling method thereof. Background technique [0002] Deep-sea earth and life science is currently a major international frontier scientific field, and its development is closely dependent on breakthrough innovations in deep-sea technology. Obtaining seabed sediments is one of the most common and important means in the process of deep sea research, which is of great significance to the study of geology, paleoclimate and microbial information in sediments. Throughout the history of seabed sediment research, it is not difficult to find that so far, research on seabed sediments in ultra-deep (water depth greater than 7,000 meters) sea areas such as the sea bucket abyss is very weak. There are 25 trenches in the world with a depth greater than 7,000 meters, of which 18 are in the Pacific Ocean, including...

Problems solved by technology

[0003] However, the existing seabed sampling is basically performed manually. Manual sampling not only needs to carry a large number of instruments into the water, but also needs to be operated in the water, which poses a great threat to the personal safety of the sampling personnel.
