Description

Column shaped deposit sample divides sampling device
Technical field
The present invention relates to a kind of column shaped deposit samples to divide sampling device, and it is heavy to be particularly suitable for field of marine ocean column Product object sample discontinuously divides sample, while sediment sample remaining in sample cell is positioned and being protected.
Background technique
When carrying out Oceanic Sedimentary Environments research, the demand according to practical study is needed, by the column shaped deposit sample of acquisition Product carry out discontinuously dividing sample according to certain sampling interval, take out the sediment sample of 1cm or 2cm every certain spacing, into Row grain size of sediment, mineral, organic carbon, surveys the follow-up tests such as year experiment at normal microelement.
The Chinese patent of notification number CN104236975B discloses that " a kind of simple marine sediment PALEOMAGNETIC STUDY divides sample to fill Set ", divide sample dedicated for environmental magnetism and the marine sediment samples of PALEOMAGNETIC STUDY;In notification number CN103630325B State's patent discloses a kind of " pushing-type quantifies layered sampler and its application method ", the Chinese patent of notification number CN105784448A It discloses a kind of " Sediment core divides sampling device ", what both devices were used to column shaped deposit divides sample.The above equipment is used When column shaped deposit sample divides sample it is whole, continuously divide sample.
According to present marine sediment research tendency, column shaped deposit sample is after fetching laboratory by pervious company It is continuous, whole that sample is divided to gradually become the difference according to factors such as research needs, measuring accuracy, sediment pile rates, every certain Spacing take out the sediment sample of 1 cm or 2cm from column shaped deposit sample and carry out dependence test, and other remaining columns Shape sediment sample should then be placed on the original place of column shaped deposit probe tube and guarantee original state as far as possible, not disturb.With convenient When oneself or other scientific research personnel carry out other follow-up studies to column shaped deposit sample, phase can be obtained according to their own needs The sediment sample answered.
Currently, device that is accurate, discontinuously dividing sample can be carried out to ocean column shaped deposit sample not yet, it is carried out Discontinuously divide sample to rely primarily on artificial progress, after obtaining column shaped deposit core sample, is divided into two to it and cuts open into two semicircles Shape columnar samples are then marked using deposit depth of the meter ruler to sample, and then are utilized and cut the tools such as native knife according to design The soil sample of interval acquiring 1 cm or 2cm thickness after soil sample is taken out, supplements the vacant locations after taking soil using the foam of respective thickness, Sediment sample remaining in sample cell is positioned and protected.
There are human errors when manually carrying out discontinuously dividing sample to column shaped deposit sample, including taking depth when soil and taking Sample thickness etc..In addition, inevitably generating destruction in sampling to the deposit of soil sample two sides, being unfavorable for residue The original state of deposit saves.Therefore, the development trend studied according to marine sediment, proposes that one kind can be to column shaped deposit sample Progress discontinuously divides the column shaped deposit of sample to divide sampling device, efficiently, accurately, do not disturb remaining sediment sample, while to residue Sediment sample is fixed and protects, and is a technical problem to be solved urgently.
Summary of the invention
