Description
Technical field
The utility model is related to the sampling bottle used in marine environmental monitoring more particularly to a kind of Oil In Seawater alanysis just
Take formula quantitative sampling bottle.
Background technology
It flourishes with China's offshore oil exploration and exploitation is movable, all kinds of row seas pollution that normal development activities generate
Object (main includes production water, sanitary sewage, drilling cuttings, mud, all kinds of rubbish) and oil spill accident lead to the wind that marine environment faces
Danger increasingly increases, and to ensure the marine eco-environment, the oils analysis in seawater has become marine environmental monitoring and appraisal
In essential analysis project.Oils analytical sampling is completed usually with spot sampling and lab analysis.Sample collection
In the process, the common brown ground glass stoppered bottles of 500ml are fixed in advance in the oil extraction device of surface layer, by sampling after ship arrival sampling area
Personnel cast aside ship carry out directly it is filling, sampling level be surface layer, i.e. underwater 0.5m.
Sampling process need to meet claimed below simultaneously：(1) water acquisition amount is no less than 450ml, while cannot overflow, and otherwise weighs
It adopts.(2) oils analysis is all made of live Duplicate Samples, and the water acquisition amount needs of parallel double samples are almost the same.(3) sampling bottle will not only enter
Water is fast, and water outlet also will avoid exiting water process middle-shallow layer water (depth of water ＜ 0.5m) from being mixed into sampling bottle as far as possible soon.
The common sampling bottle used at this stage, sample collector, which needs to accurately control sampling bottle, enters the residence time after water, but
It is difficult in actual mechanical process while meets above-mentioned sampling request, sample adopts phenomenon and happens occasionally again.
Therefore, in Oil In Seawater alanysis work, common sampling bottle is that sampling operation brings great inconvenience.
Utility model content
In order to overcome the shortcomings of that existing common sampling bottle is difficult to meet particular sample requirement, the utility model provides a kind of
The portable quantitative sampling bottle of Oil In Seawater alanysis.
In order to achieve the above object, technical solution used by the utility model is：The utility model includes bottle, in bottle
Body is internally provided with hollow organic glass ball, and the top of the bottle is equipped with arc bottleneck, and the upside of the arc bottleneck is equipped with
Bottleneck, is equipped with osculum between bottleneck complement of an arc shape bottleneck, the arc diameter of arc bottleneck and the center of circle with hollow organic glass
Ball is identical.
When the utility model is used, after the sampling bottle that bottle is placed in surface layer oil extraction device reaches designated depth, seawater sample
Product enter sampling bottle, while organic glass ball floats with seawater.After organic glass ball reaches at the top of sampling bottle, no longer float, but
Because the pressure that sampling bottle water inlet seawater applies organic glass ball is more than buoyancy suffered by it, seawater is gone successively to.With sample
Water continues growing in bottle, and the water-immersed volume of organic glass ball increases, and suffered buoyancy increases, but top pressure is not
Become.When buoyancy is more than pressure, bottle sealing, seawater can not be entered back into sampling bottle by organic glass ball, and sampling terminates.Sampling bottle
In exiting water process, buoyancy is constant suffered by organic glass ball, but pressure becomes smaller, and bottle sealing is even closer, and shallow seated groundwater is same
Sample bottle can not be mixed into.After the completion of sampling, a small amount of seawater that sample bottle bottle mouth position accumulates is discharged by the discharge outlet of side.
The diameter of bottle is more than the diameter of hollow organic glass ball.
It is smooth surface on the inside of the surface of hollow organic glass ball and arc bottleneck.
The analysis of the utility model combination principle further includes a kind of production method, the specific steps are：
The first step selectes bottle material, is common sampling bottle versatile material；
Second step, the selection of organic hollow glass ball：According to the size of bottle, suitable organic hollow glass ball is determined,
The diameter of organic hollow glass ball is less than the diameter of bottle, selected to meet condition：When at extra large underwater 0.5m, You Jikong
3/4 volume of heart glass marble is immersed in the water rear suffered buoyancy and is more than top pressure, i.e., bottleneck is in sealing state at this time.
Diameter basis for selecting following formula：
ρgπR3=ρ ghS
ρ represents density of sea water, and R represents the radius of organic hollow glass ball, and h represents the depth of water, and S represents bottleneck cross section face
Product.
In injection molding or compression moulding, first organic hollow glass ball 3 is placed in 1 mold of bottle, it is whole in progress
Body injection molding.
Third walks, and sampling bottle bottleneck diameter is chosen：According to water inlet needs, scope of design value is 1-2cm.
4th step, the selection of sampling volume：It is water-immersed at the end of sampling after 3 diameter of organic hollow glass ball determines
Volume can determine, can realize that sampling bottle is quantified according to required sampling quantity by the sampling bottle height for designing different
Sampling, and it is reproducible.
The beneficial effects of the utility model have：
1. the utility model is to the sample collector in Oil In Seawater alanysis work without particular/special requirement；
2. the utility model to the residence time no requirement (NR) after entering water, avoids that the residence time is long and what water sample overflowed show
As sampling process is more calm；
3. the utility model can be designed according to sampling request completes relatively accurate quantitative sampling and reproducible, really
The water consistency of parallel double samples is protected；
4. the utility model completely avoids exiting water process middle-shallow layer water and is mixed into sample bottle, easily meet the same of sampling request
When improve sampling success rate.
