The vertical characteristics of oils in water body of different shape is different, and oil slick (or claiming oil film) is present in the top layer of water body, and oil emulsion is more higher close to water body top layer content, and dissolved oil is uniformly distributed in water body.Due to the different shape of oils vertical characteristics in water body this feature different, the sampling method of oils sample and the quality of the sampling thief of use to water quality oils monitoring result most important.Adopt the different method of samplings, or use oils sample in the samplers sample water body of multi-form, different size, because the ratio of oil slick, oil emulsion and dissolved oil in oils sample is different, cause Monitoring Data not only to lose representativeness, and lack comparability." water quality sampling technological guidance " (HJ494-2009) regulation for this reason: measure oils water sample, should gather column water sample at the water surface to underwater 300mm, and sample separately, all for measuring.This regulation comprises which floor implication following: the water sample gathering column, and post height is 300mm; In the cylinder water sample gathered, the water sample amount of each layer should be identical; When sampling volume one timing, cylindrical cross-sectional area and diameter are also definite value.Although clear and definite regulation and technical requirement have been made in " water quality sampling technological guidance " (HJ494-2009) collection to water quality oils sample, still lack at present and met this regulation corresponding water quality oils sample device completely.
There is following defect in oils sampling thief in the past:
(1) due to the specification (bottleneck diameter and bottle height) of the not clear and definite sampling bottle of this oils sampling thief, the water sample of collection is caused to be difficult to obtain the water surface to underwater 300mm column water sample and each layer water sample amount is identical.
(2) because base and stopper are in the positive front end of bottleneck, very easily disturbance top layer oil film during collected specimens, causes in the column water sample of collection and does not collect representative oil film.
(3) sampling bottle of this sampling thief is also storage sample container, sample need be transferred in separating funnel during sample analysis.Because oily substance is very easily adsorbed onto solid surface, sample needs after being transferred to separating funnel to wash this sampling bottle with phenixin, and cleansing solution is transferred in separating funnel, and phenixin dissolves the plug at the bottom of bottle, this will affect the accuracy of measurement result.
(4) plug at the bottom of bottle, to the poor sealing of aperture, easily causes water sample seepage in transportation.
Because existing oils sampling thief exists above defect, each monitoring unit uses this oils sampling thief to be difficult to obtain the Monitoring Data of comparability.
Summary of the invention
The invention provides a kind of special water quality oils sample fidelity sampler, to solve current water-quality sampler and can not meet the problem that " water quality sampling technological guidance " (HJ494-2009) specify oily substance Sampling techniques.
The technical problem to be solved in the present invention:
