Marine seabed sampling device

Abstract

The invention relates to an ocean seabed sampling device which comprises a cylindrical shell and is characterized in that a conical collecting groove frame is arranged at the bottom of the shell, a cross-shaped fixing frame is fixedly arranged in the collecting groove frame, a lifting seat is arranged in the shell, a driving motor is fixedly arranged at the bottom end of the lifting seat, a rotating shaft is fixedly connected to the bottom output end of the driving motor, the bottom end of the rotating shaft is fixedly connected with the middle position of the cross-shaped fixing frame, a servo motor is arranged at the top end in the shell, a threaded rod is fixedly connected to the bottom output end of the servo motor, a conical base is arranged at the bottom in the shell, a fixed ring seat fixedly connected with the inner wall of the shell is fixedly arranged at the edge of the conical seat, a ring block is fixedly arranged at the edge of the collecting groove frame, a hanging ring is fixedly arranged at the top end of the shell, bearing blocks are fixedly arranged on the two sides of the shell, and a monitoring device is arranged at the top of the shell. The device is convenient to use, high in collection speed and capable of preventing collected precipitates from shaking off.

Description

technical field [0001] The invention relates to the technical field of seabed sampling, in particular to a marine seabed sampling device. Background technique [0002] There is a layer of mysterious but very research-worthy seabed sediments in the depths of the ocean. Seabed sediments are of great significance for understanding the changes of the earth's environment, revealing the inner connection between the earth's environmental systems, and predicting the long-term climate change in the future. Submarine sediment sampling and in-depth research can enable human beings to obtain very important scientific value in the fields of marine scientific research, marine environmental research, marine resource exploration, marine engineering exploration, etc. It is of great strategic significance for human beings to understand the earth and develop the ocean , the existing ocean bottom sampling device has a single structure, slow sampling efficiency, and is prone to shaking during th...

[0002] There is a layer of mysterious but very research-worthy seabed sediments in the depths of the ocean. Seabed sediments are of great significance for understanding the changes of the earth's environment, revealing the inner connection between the earth's environmental systems, and predicting the long-term climate change in the future. Submarine sediment sampling and in-depth research can enable human beings to obtain very important scientific value in the fields of marine scientific research, marine environmental research, marine resource exploration, marine engineering exploration, etc. It is of great strategic significance for human beings to understand the earth and develop the ocean , the existing ocean bottom sampling device has a single structure, slow sampling efficiency, and is prone to shaking during the lifting process, causing the sampled sediment to scatter, which cannot meet people's needs
