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

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1-5 and Figure 8 A hydraulically driven deep-sea biological sample holder includes a driving device, a reagent compartment 1, a biological sample compartment 3 and a combined frame; the driving device is specifically: a magnetic pump 8 drives seawater through the first water injection port 8-1 , the second water injection port 8-2 and the third water injection port 8-3 are sequentially injected into the cover anti-rotation plug, the cover closure sliding mechanism and the reagent compartment 1, wherein the compartment body of the magnetic pump 8 passes through the middle splint 4 The position of the round hole is limited, and the water inlet and outlet are seated in the transition sleeve 7. While making up for the lack of the ...

Abstract

The invention belongs to the technical field of marine biological sampling and storage, and relates to a hydraulically driven deep-sea biological sample storage device, including a driving device, a reagent cabin, a biological sample cabin, a combined frame, a cover anti-rotation plug and a cover closure sliding mechanism , the combined frame includes an integrated pressure plate, an intermediate splint, a base plate and a support rod, the driving device is arranged on the intermediate splint and the base plate, the biological sample compartment is arranged on the integrated pressure plate and the intermediate splint, the reagent compartment The reagent output pipeline communicates with the biological sample chamber, the cover anti-rotation plug communicates with the driving device through the large R pipeline, and the cover closing and sliding mechanism is connected with the driving device through a smooth round inner wall hole tube. The invention is light in weight and small in size, and can be used on underwater robots (ROVs) and underwater landers (Landers) to effectively preserve acquired biological samples, and can also be used independently after being equipped with a power supply, trapping and collecting organisms on the seabed and treating them It is fixed.

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...
