Description
Technical field
The present invention is a kind of halmeic deposit pore water original position automatic acquisition device easy to operate, belongs to halmeic deposit
The innovative technology of pore water original position automatic acquisition device.
Background technology
Cold seepage leaking substance is distributed widely in global ocean environment.It maintains cold spring blowby areaization can be certainly
Foster biocoene such as clam class, mussel and Ridgeia.These cold spring macroscopic view biocoenes depend in deposit is detested by methane
The hydrogen sulfide that oxygen aoxidizes and the microbial consortia of sulfate reduction coupling generates.Hole in acquisition and analysis cold spring area deposit
Gap water is most important to understanding the biogeochemical process of cold spring.However it is cold currently based on the deep-sea that bathyscaph or ROV are used
The acquisition of spring Sediment Pore Water is only intubated and infiltration two kinds of sampling modes of dialysis.It is desirable that intubation, which takes Sediment Pore Water sample,
Centrifugation and high-pressure compressing, and can result in deposit after sampling and seriously destroy.Especially intubation sampling in deep-sea is lacked there is very much
Point：1）Depth selection is shallow, is often less than 30cm；2）Usually take meeting in the deposit mainly acquired less than good sediment sample
Contain the common mussel of cold spring leakage environment or clam bed, Bivalve shell bits, Ridgeia root or carbonate rock fragment；3）Cold spring
It is usually related to animal community, it relies on intubation and seep fauna COMMUNITY CHARACTERISTICS hole water chemistry is taken to have stringent limitation；4）It is intubated back
During receipts, mushroom cell can be destroyed due to being depressured or heating up and changes pore water intermediate ion concentration；5）It is hydrated in piston
Object decomposes the integrality for causing gas expansion that can destroy sediment sample in intubation.And it is to be based on fluid balance to permeate dialysis sampling
Principle makes to be present in intracellular fluid and its surrounding medium passes through dialysis membrane and reaches balance.It is heavy that infiltration dialysis sampling will not carry
Product object, and utmostly reduce the process after sample collection.It is sampled accordingly, with respect to intubation, infiltration dialysis is one universal
Replacement tool, for acquiring deposit in different aquatic environments such as lake, wetland, sabkha.Although infiltration dialysis can gram
Some problems of clothes intubation sampling, but in removal process, there is dialysis after deep-sea samples in existing infiltration dialysis probe tube
Fluid in bag can reach balance again with surrounding seawater, change the deposit pore water ion concentration of in-situ acquisition.

Specific implementation mode
Embodiment：
The structural schematic diagram of the present invention is as shown in Figure 1, the halmeic deposit pore water easy to operate of the present invention is adopted automatically in situ
Acquisition means, include exterior tube handle 1, inner tube handle 2, external sampling pipe 3, internal sample pipe 4, metallic plate 5, metal nose cone 6,
Connecting tube 11, outer handle 1 are connected by connecting tube 11 with reeded external sampling pipe 3, external sampling pipe 3 and round metal
Conehead 6 is connected, and metallic plate 5 is fixed on external sampling pipe 3, and internal sample pipe 4 is nested in external sampling pipe 3, inner tube handle 2
It is nested in exterior tube handle 1, inside handle 2 is connected with internal sample pipe 4.
In the present embodiment, above-mentioned metallic plate 5 is corrosion and easy fracture in order to prevent using the purpose of metal material, and is prevented
Sampling apparatus penetrates too deep, and metal nose cone 6 is that sampling apparatus is made easily to prick into halmeic deposit using the purpose of metal material,
And for anticorrosion.
In the present embodiment, above-mentioned internal sample pipe 4 is by 7 with fluted 13 the first dialysis chamber 9 and 1 un-grooved
The second dialysis chamber 14 be connected with each other by radial direction seal ring 7, and with fluted 13 dialysis chamber 9 and un-grooved
Dialysis chamber 14 is not alternate setting.
In the present embodiment, dialysis bag 8 is housed in the dialysis chamber 9 of above-mentioned band fluted 13.It is equipped with and fills inside dialysis chamber
The dialysis bag 8 of full deionized water, for acquiring the pore water in halmeic deposit.
In the present embodiment, 4 sealing rings 15 are housed on above-mentioned radial direction seal ring 7.Sealing ring is housed on radial direction seal ring 7
15 so that dialysis chamber is closed relative to the external world, prevents sampling apparatus in removal process in dialysis chamber in dialysis bag 8
Pore water receive pollution.
In the present embodiment, between the dialysis chamber 9 of above-mentioned adjacent band fluted 13 and the dialysis chamber 14 of un-grooved by
Solid bar embolism 10 seals.Solid bar embolism 10 can make fluid not circulate between the chambers.
In the present embodiment, above-mentioned metallic plate 5 is fixed on by fixing piece 12 on external sampling pipe 3.Its effect is to prevent from adopting
