Double-layered plankton sampling device

Abstract

The invention relates to a double-layered plankton sampling device and belongs to the field of ocean exploration and development. The double-layered plankton sampling device comprises an upper cover plate, a framework, a first wall surface, a first rotary door, a second rotary door, a second wall surface, a third wall surface, a fourth wall surface, an organism storage bucket, a pressing plate, apressurizing motor, a temperature control device, a rotary motor and a lower cover plate; the rotary motor drives the first rotary door and the second rotary door to rotate and two organism samples are collected and stored into an upper part and a lower part of the organism storage bucket respectively, so that the utilization rate of the sampling device is improved; soft membranes are attached onthe first rotary door, the second rotary door, the first wall surface, the second wall surface, the third wall surface and the fourth wall surface, so that the organism samples are in soft contact with the sampling device and mechanical damages of the organism samples are avoided; when the organism samples are collected, seawater in a sampling environment is remained and subsequent researches areeasy to carry; a mechanical arm of a submersible clamps the whole sampling device and is not in contact with the organism samples, so that damages to the organism samples are not caused.

Description

technical field [0001] The invention relates to a double-layer plankton sampling device, which belongs to the field of marine exploration and development. Background technique [0002] With the continuous deepening of various marine scientific research and the development and utilization of marine resources, how to quickly, conveniently and effectively conduct survey and sampling of marine organisms to obtain first-hand marine biological scientific research samples and comprehensively understand the biological resources of specific sea areas , has become a matter of urgency. Biological samplers are one of the important tools for obtaining biological samples on the seabed. At present, there are two methods of capturing plankton: one is to use deep-sea trawls, samplers or grabs to obtain biological samples, and then drag them ashore for filtration and separation. However, this method will seriously damage the living environment of seabed organisms; another method is to use de...

Biological samplers are one of the important tools for obtaining biological samples on the seabed. At present, there are two methods of capturing plankton: one is to use deep-sea trawls, samplers or grabs to obtain biological samples, and then drag them ashore for filtration and separation. However, this method will seriously damage the living environment of seabed organisms; another method is to use deep submersible technology, that is, to use underwater robots to use manipulators to capture organisms and put them into collection bins, but the biological samples are transported to the sea surface. In the process, the environment where the biological samples live changes drastically compared with their living environment, which often leads to damage and death of the biological samples. The manipulator will damage the samples to a certain extent during the process of capturing the biological samples, which will affect the later research in the laboratory. In addition, if the biological sampler only collects one sample at a time, the utilization rate of the sampler is not high, so a double-layer plankton sampling device is required
