Convenient-to-clean plankton sampler

Abstract

The invention relates to a convenient-to-clean plankton sampler, and belongs to the field of marine exploration and development. The convenient-to-clean plankton sampler comprises a sampling device and a cleaning device, and the sampling device is mounted on the cleaning device; the sampling device comprises an upper cover plate, a frame, a first wall surface, a revolving door, a second wall surface, a third wall surface, a fourth wall surface, a biological storage barrel, a pressure plate, a pressurizing motor, a temperature control device, a rotating motor, a lower cover plate and a handle;the cleaning device comprises a rotating disc, a cleaning barrel and a bearing; the lower end of the frame is clamped into the rotating disc of the cleaning device; the handle is rotated by a hand torotate the frame, and the frame is enabled to rotate along with the rotating disc relative to the cleaning barrel of the cleaning device; debris such as alga on the outer sides of the frame, the firstwall surface, the second wall surface, the third wall surface and the fourth wall surface is conveniently cleaned by bristles on the cleaning barrel; the revolving door, the biological storage barrel, the first wall surface, the second wall surface, the third wall surface and the fourth wall surface are coated with soft films, so that biological samples are in soft contact with the sampling device, and mechanical damage to the biological samples is avoided.

Description

technical field [0001] The invention relates to a plankton sampler which is convenient to clean, and 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 ...

Problems solved by technology

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 capture organisms with manipulators and put them into collection bins. 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 damage the samples to a certain extent during the process of catching the biological samples, which will affect the later stage in the laboratory. In addition, the sampler will inevitably be stained with other debris such as seaweed during transportation to the sea surface, so a plankton sampler that is easy to clean is needed
