Water pressure driven deep-sea organism sample storage device

Abstract

The invention belongs to the technical field of marine organism sampling and storage, and relates to a water pressure driven deep-sea organism sample storage device. The water pressure driven deep-seaorganism sample storage device comprises a driving device, a reagent cabin, an organism sample cabin, a combined frame, a sealing cover anti-rotation bolt and a sealing cover closing sliding mechanism, wherein the combined frame comprises an integrated pressing plate, a middle layer clamping plate, a bottom plate and a supporting rod; the driving device is arranged on the middle layer clamping plate and the bottom plate; the organism sample cabin is arranged on the integrated pressing plate and the middle layer clamping plate; the reagent cabin communicates with the organism sample cabin through a reagent output pipeline; the sealing cover anti-rotation bolt communicates with the driving device through a large R pipeline; and the sealing cover closing sliding mechanism is connected with the driving device through a smooth circular inner wall hole pipe. The deep-sea organism sample storage device is light in weight and small in size, can be carried on an underwater robot (ROV) and an underwater lander for use, can effectively store obtained organism samples, can also be independently used after being equipped with a power supply, and traps and collects organisms on a seabed site and fixes the organisms.

Description

technical field [0001] The invention belongs to the technical field of marine biological sampling and storage, and relates to a water pressure-driven deep-sea biological sample storage device. Background technique [0002] The development and utilization of marine biological resources has become one of the focuses of competition among the world's major marine countries. Deep-sea biological sampling is a prerequisite for the development and utilization of marine biological resources. Conventional samplers do not carry out any protective treatment on biological samples. During the long stage from seabed sampling to experimental analysis, many active substances and genetic materials are easily degraded, which will affect research. [0003] During the transfer of deep-sea biological samples, the samples are usually sealed and preserved with a suitable fixative according to the research objectives, and the best effect is to preserve the samples directly at the sampling site. Due...

Problems solved by technology

[0004] The patent of publication number CN108142384A discloses a deep-sea in-situ bio-fixed trap, but its structure can only collect and fix the RNA of deep-sea biological samples by trapping, and the ratio of the fixative solution cannot be changed, so the applicability is low

In addition, the method of pressing the trapping cylinder into the reagent chamber driven by the motor may damage some biological samples, and it is also prone to failure or poor sealing, resulting in failure of sample preservation
