Description
Technical field
The utility model belongs to the marine environment investigation technical field, and specifically, relating to a kind of is bottom underwater water sample original-position collecting device in the electric-controlled ball valve formula.
Background technology
Along with the exploitation of ocean, environmental pollution is also day by day serious.Wherein the marine oils pollution problem attracts wide attention.The oil pollution ocean, bring huge harm to the marine eco-environment.What stand in the breach is to account for the planktonic organism of the marine food chain lowermost layer of about whole ocean gross primary productivity 95%.The oil that is dissolved in seawater is larger to fish harm.Its infringement various tissues of fish and organ.Oil to fish egg and larva harm obviously.Contain the oil of 0.1 milligram in one liter of seawater, it is all lopsided will causing hatching juvenile fish out, and can only survive 1～2 day.Live in the zoobenthos in seabed, as sea cucumber, various shellfish, starfish, sea urchin etc., extremely responsive to oil,, even only have the oil of minute quantity in living environment, also can affect the movable and breeding of shellfish.Cause aquatic resources to be destroyed.Oil pollution generally all is with just like benzopyrene, Benzanthracenes carcinogen.These materials are easy in sea life cylinder accumulation and enrichment, are difficult to decompose.The content that is subject to carcinogen in the food of polluted ocean is high more up to a hundred to several thousand times than non-ocean food.The edible marine product that pollutes just likely will wait carcinogen to take in body, finally be detrimental to health.Biologic chain is polluted.Take seabird as example, thus can cause serious stimulation to stomach and intestine because oil enters into alimentary canal, intrahepatic fat is changed, adrenal gland enlarges, and makes the seabird apocleisis that becomes, and is slowly hungry to death.Live in the extra large beast in oil pollution district, as very blunt in the sense of smell of whale, dolphin, sea lion, sea otter, all injuries that cause so bring.It is reported, over nearly 50 years, because of existing more than the 1000 kind of sea hydrobiont extinction of oil pollution, sea life have reduced 40%.Oil pollution worsens water body.
Enter the oil in marine environment, its natural degradation and microorganism are decomposed, and can consume dissolved oxygen DOs a large amount of in seawater., for oxidation 1 gram oil, approximately need the oxygen of 3～4 milliliters.1 liter of oil is by complete oxidation, and the oxygen in the 400000 liters of seawater that will run out, be equivalent to 1 square metre of area, the whole dissolved oxygen contents in dark 400 meter water columns.The seawater severe depletion of oxygen, bring disaster to all sea life, from planktonic organism to huge extra large beast.Oils can form the solid block of large stretch of pitchy simultaneously, destroys natural landscape.Be subjected in the alkali flat of oil pollution, toxic action is for many years sustainable, hinders biological cluster again.In decades recently, the decline of China coast aquatic resources, move outside fishing ground, and traditional economic fish amount of fishing obviously descends, and the oil pollution that is subject to ocean has some relations.
On September 2nd, 2011, CNOOC's Peng Lai 19-3 oil field leakage of oil event, also claim Kang Fei leakage of oil event, Bohai Sea ecologic environment has been caused serious pollution, due to law and the monitoring detection means not in place, cause event to delay effectively to be processed, in the joint investigation process, the water sampling equipment of use and method are subjected to abroad expert's query.
The Sampling Survey of oleaginousness in the different depth water body, for the diversity of analysis and research according to oil existence form in water body, nonunf ormity and the oil pollution condition to water body, gather the existing way of floating oil, dispersed oil, oil emulsion and dissolving wet goods various ways, understand oils in the rule that water body shifts, decomposes, spreads and change, for oceanographic survey and scientific research, have great importance and act on.
Gathering the oils water sample has its singularity, and the materials such as organic glass, rubber are easily stained by oil, can not be used for gathering the oils water sample.
The original position water sampling of biological species research use has also proposed same request for utilization, namely keeps the clean state after sampling bottle is sterilized, and starts to gather water sample when arriving set depth, guarantees that the water sample that gathers represents the original position state of collection point.
Be not used for gathering at present the bottom collector of original position water sample.It is existing that what generally use is mechanical type original position hydrophore, utilization be mechanical principle, hydrophore is put under water, drops to set depth, the buoyancy of ball float pulls open the lid of container, after container is filled water, rises to the water surface.The shortcoming of its existence is:
1. the degree of depth can not reach requirement: the mode of prior art, be not suitable for the degree of depth below 10 meters, and because under water under pressure-acting, uncap needs larger power, ball float and gravity are difficult to realize;
2. severity control is inaccurate under water: severity control calculates by the length that hawser descends under water, is subjected to interferences such as ocean current to need to estimate in heeling condition, and the sampling depth position is inaccurate;
3. hawser easily is wound around, and the water success ratio is adopted in impact: when the degree of depth is darker under the effect of current the hawser of ball float and hydrophore hawser easily be wound around, the impact normal operation.
4. adopt after water the lid on bottle poorly sealed: after sampling bottle is filled under water, gravity and buoyancy make lid fully not seal and to close, water sample in uphill process in sampling bottle easily is subject to the interference of other water layer, water sample mixes can not reflect the set depth water quality condition truly, utilize result and the actual result that such water sample draws to have certain difference, thereby be subject to expert's query.
As seen, existing machinery formula hydrophore technology in adopting the water process, realizes adopting water by lid switch, can cause and close the not tight seepy question of lid, makes thus water sample untrue.Due to above deficiency, bottom water sample in can't gathering, inefficiency when the water sampling of top layer, the normal use and test result of water sample impact of collection.
Existing deep-casting device, its principle is to put under water with tubular container, after arriving set depth,, the sealing of the upper and lower side of tubular container, collects the water sample of set depth.But this mode contacts the water sample of different levels in the tubular container decentralization process, and the water sample state generation of set depth is disturbed, and can not meet the requirement of in-situ acquisition, is not suitable for oils and biological species water sampling.
