Problems solved by technology

However, the situation on the bottom of the sea is complicated. For example, when sampling in kelp culture areas, the mud picker is easy to touch the rope used for culturing kelp and closes. Once the mud picker is closed on the seabed, it cannot be opened again under the sea.

Abstract

The invention relates to a hand-operated sediment collecting device which comprises a mud-collecting device, a hand-operated winch, and a bearing rope; a main rotation axis of the hand-operated winch comprises an inner-layer rotation axis and an outer-layer rotation axis; the rotation axis has a cylindrical structure; the inner-layer rotation axis has a columnar structure; the inner-layer rotation axis is coaxially sleeved by the outer-layer rotation axis; a fixed isolation device is disposed on the outer-layer rotation axis, and the outer-layer rotation axis is divided into a first working area and a second working area; an inner-outer layer junction valve is disposed on the isolation device; the inner-layer rotation axis and the outer-layer rotation axis are selectively connected by the inner-outer layer junction valve; the bearing rope comprises a first bearing rope and a second bearing rope; one end of the first bearing rope is wound on the first working area, the other end is connected with a bearing crossbeam of the mud-collecting device; one end of the second bearing rope is wound on the second working area, the other end is connected with a panel connecting chain of the mud-collecting device. The invention has a simple structure, is convenient for manufacturing, has simple and feasible operations, high using efficiency and accuracy, and is applicable to popularization.

Description

technical field [0001] The invention relates to the technical field of sediment sampling, in particular to a manual sediment collection device. Background technique [0002] Field sampling is an important part of marine scientific research. It is not only the basis of all research work, but also largely determines the quality of the overall project completion. Marine sediment sampling is one of the important contents of field survey sampling, and almost every comprehensive sampling task includes sediment sampling. From the perspective of research disciplines, sediment sampling involves many fields of oceanographic research. For example, as an important branch of marine ecology research, marine benthic ecology research, its samples are obtained through sediment sampling. Samples of macrobenthic invertebrates (particle size greater than 0.042 mm) are obtained by panning the sediment and then sorting out the animals contained in it; samples of small or microbenthos (particle...
