Zooplankton sampling device capable of convenient observation

Abstract

The invention relates to a zooplankton sampling device capable of convenient observation and belongs to the field of marine exploration and development. The device comprises an upper cover plate, a frame, a first wall surface, a rotating door, a rotating disk, a second wall surface, a third wall surface, a fourth wall surface, a biological storage bucket, a pressing plate, a pressurization motor,a temperature control device, a rotating motor, a lower cover plate, a base, a bearing, and a handle, wherein the lower end of the frame is clamped in the rotating disk; the hand grips the handle to rotate the frame to enable the frame to rotate along with the rotating disk, so that biological samples can be observed in all directions; a manipulator of a submersible clamps the whole sampling device without touching the biological samples, so that the biological samples can not be damaged, and subsequent experimental studies are facilitated; and soft films are attached to the rotating door, thebiological storage bucket, the first wall surface, the second wall surface, the third wall surface and the fourth wall surface, so that the biological samples can be in soft contact with the samplingdevice, and the mechanical damage of the biological samples is avoided. While the biological samples are collected, seawater in sampling environments is retained, and the subsequent studies are facilitated.

Description

technical field [0001] The invention relates to a convenient observation 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...

The biological sampler is 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, and the manipulator will cause a certain degree of damage to the samples during the process of catching the organisms, which will affect the later stage in the laboratory. In addition, biological samples need a large number of observations in the later research process, so a plankton sampling device that is convenient for observation is needed
