Visual multi-connected sampling system of plankton and use method thereof

Abstract

The invention relates to the technical field of research on marine life equipment, in particular to a visual multi-connected sampling system of plankton and a use method thereof. The visual multi-connected sampling system of plankton comprises sample collectors, mesh bags, a framework, springs, a brake, a driving separation mechanism and a plurality of moving rods, wherein the moving rods are arranged in the framework, the inlet ends of the mesh bags are arranged at different moving rods respectively and are opened or closed through rotating of the moving rods, the brake is arranged on the upper side of the framework, one end of each moving rod extends to the outside of the framework, the upper side of the end is connected with the brake before sampling is started, and the lower side of the end is connected with the bottom surface of the framework through one spring; after sampling is started, respective moving rods are separated from the brake in sequence by the action of the driving separation mechanism and the springs, the inlet ends of the mesh bags are opened when the moving rods are separated from the brake, and the sample collectors are arranged at the bottoms of the mesh bags. The visual multi-connected sampling system of the plankton achieves horizontal and vertical sampling in continuous water layers and improves the collection frequency of the plankton.

Description

technical field [0001] The invention relates to the technical field of marine biological equipment research, in particular to a plankton visualization multi-sampling system for plankton sampling and a method for using the same. Background technique [0002] Plankton trawling is one of the important tools for collecting plankton samples. It has the advantages of strong controllability, large sampling volume and convenient operation. It is widely used in many marine plankton research projects. The traditional trawling system uses an integrated mesh bag with no interface, which is inconvenient and time-consuming to replace after each sampling. At the same time, the traditional trawling system cannot realize the sampling of plankton in different depth ranges and cannot observe the underwater environment. Multiple samples are taken to achieve the purpose of sampling. These deficiencies seriously affect the speed of sampling and bring a lot of inconvenience to the staff of offshor...
