Abstract

The invention discloses a sediment trap which comprises a conical funnel, sampling bottles, a sealed closing cover, a push-pull electromagnet and an automatic control system, wherein the conical funnel is butted with the sampling bottles and is used for collecting and storing sediments in seawater; the automatic control system is capable of presetting time, the sealed closing cover on the inner side of the sampling bottle is controlled to open and close by virtue of the push-pull electromagnet on the outer side of the sampling bottles, and the sediments are stored in the sampling bottles of different diameters in a layered manner; and the multiple sampling bottles are connected and detached by virtue of threads and sealing rings and can be repeatedly used. The sediment trap disclosed by the invention is small in volume, and the various components can be detached and stored and are convenient to carry; the sediment trap is light in weight and low in construction cost, and the main partsare made of acrylic; the sediment trap is simple in structure and easy to distribute and recover; the sediment trap can be used with hydrodynamic force and sediment observation instruments, the observation time is saved, and the observation efficiency is improved; and the sediment trap is stable in structure and applicable to sampling and observation of sediments in the river mouth, coast and coastal seawater with strong hydrodynamic conditions.

Description

Technical field [0001] The invention relates to the technical field of marine sedimentary dynamic observation equipment, in particular to a sediment trap, which is used for collecting sedimentation materials in estuaries, coasts and offshore seawater. Background technique [0002] Marine sediments are the result of various marine sedimentation processes and record relevant information about the physical, chemical, and biological processes in the marine environment. The sediment trap is a sampling device used to capture and collect sedimentation materials in seawater. It is mainly used to monitor sediment flux in situ, and obtain the source, composition, and temporal and spatial changes of sedimentation materials through sample analysis. The necessary equipment for marine sedimentary dynamics and marine biogeochemical research. [0003] In recent years, with the continuous in-depth research on sediment movement and geomorphological evolution, material transportation and ecological ...
