Abstract

The invention belongs to the technical field of ocean engineering, and particularly relates to a submarine sediment sampling device for ocean engineering. in view of the problems that a device is relatively low in stability, and cannot perform massive sampling simultaneously, expel benthos or prevent re-dropping of a sampled sediment into ocean, the following scheme is provided: the sampling device comprises a buoyancy plate, wherein a fixed outer ring is arranged on the external wall on one side of the bottom of the buoyancy plate; a water-proof motor housing is arranged on the external wallof the bottom of one side of the fixed outer ring; motors are arranged in the water-proof motor housing; brackets are arranged on the external wall of the bottom of one side of the fixed outer ring; and the brackets are L-shaped. The stability of the sampling device is improved; infaunae are expelled by the vibrating action of the motors and the collision action of ball bodies and arc slide blocks, so that interference with a sampling process is avoided; the sampled sediment is separated from a submarine plane, so that the sampling is facilitated; and a pull plate is pulled upwards to allow clamping blocks to clamp the submarine sediment drilled out.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a seabed sediment sampling device for marine engineering. Background technique [0002] The sampling methods of seabed sediments are mostly gravity piston sampling and vibrating piston sampling, etc. The seabed sediment sampling devices in the prior art cannot specifically sample the seabed sediments in shallow waters. The suspended floating ball maintains the vertical balance of the sampling tube underwater. Although the volume of the device is reduced, it cannot completely maintain the vertical state of the sampling tube, and the fluctuation of the seawater flow is relatively large, which will also make it difficult for the device to be in a balanced state. , it is difficult to ensure that the sampled sediment does not fall into the seawater at the moment of taking it out, which will cause sampling failure. The most important thing is that the seabed environment is c...
