Description
Technical field
It the utility model is related in hydrometeorology monitoring and sampling field collected to the water sample of surface water, be specially a kind of earth's surface
Water isotope, water chemistry layered water sample harvester, suitable for the stable isotope and water chemistry of different depth level surface water
The water sampling of analysis.
Background technology
Surface water（River and lake）Hydrological characteristics be many factors comprehensive function as a result, the physical property of water body
Such as silt content, water temperature key element are the concentrated expression of basin soil property situation, Land-cover changes, topographic and geologic condition；And river
（Lake）The chemical property of water（Leading ion, hydrogen and oxygen stable isotope, solid total soluble matter, pH etc.）Then can interpretation go out river water
Flow through environment, form conversion process and the degree by the effect of human activity etc..Therefore river（Lake）Water sample is in hydrology, geography
Have the function that in research it is important, how the acquisition earth's surface river of reasonable science（Lake）Water water sample has become current water circulating research
In important step, be quantitative study region runoff process, more water bodys conversion, the necessary acquisition condition of water quality distribution characteristics,
It is a current hydrometeorological monitoring department problem urgently to be resolved hurrily.
As the surface water Isotopic Data of one of isotope hydrology important foundation composition, it is gathered and monitoring is got over
More to be paid attention to be subject to everybody, the collection for the earth's surface water isotope carried out in the past concentrates on underwater a certain fixed position substantially（Water
Lower 1 meter of face）, sampling process is relatively simple, since surface river water, lake water etc. are controlled by riverbed physiognomy and different supply source, makes
The obvious physicochemical properties of difference are formed into river water from river surface to river water bottom（Lower part sediment charge is higher, water temperature is low,
Sediment charge high water temperature in top is high）.Traditional method of sampling is difficult to understand the hydrology information contained in different level river water
（Such as pollutant load, water temperature, ion concentration and stable isotope equal distribution feature in different level river water）, and it is layered surface water
There has been no ripe product appearance for the device of sampling.With the development of economy and society, water resource has become restriction economic development
Strategic resources, and as the surface water resources of water resource important composition, the environment that is contained in its different level water body and
Geography hydrographic information increasingly attracts attention, how scientific and reasonable realizing surface water Stratified Sampling has become each hydrology gas
As station net and the important process part of scientific research institution.
The collection of earth's surface water isotope is a link important in isotope hydrology research, is directly related to basin water
Literary process analysis procedure analysis, separation, the precision of cienega transformation assay result, and then determine the credible result of quantitative study
Degree.Unscientific sample mode can not only waste funds and the time of researcher, while will also result in the distortion of scientific research result.Point
It is 1 to face two most intractable problems at present during the collection of layer river water isotope water chemistry sample）How to realize that river water layering is received
Collection, 2）How prevention evaporation during river water Stratified Sampling, reduce river water sample and disturbed by key elements such as extraneous water body and gases.
Existing water sampler is mainly more bags（More bottles）Hydrophore either spherical cap formula hydrophore：More bottles（Or more bags）Hydrophore is
Multiple sounding bottles (or water acquisition bag) are radially installed on a hanger, with making the mode controls such as hammer, pressure switch element, cable
Hydrophore switch processed, this sampling apparatus carrying is extremely complex, while occurs that different level water body exchanges in sampling process,
Error is brought to later stage water sample test analysis；Spherical cap formula hydrophore（Also known as Fan Duoen hydrophores）By water acquisition cylinder, spherical cap, release
Device, fixed frame and steel wire rope groove and form the part such as hammer, when hydrophore is transferred, two spherical caps open wide, and it is deep to reach predetermined water acquisition
After degree, release makes hammer two spherical caps is closed sampling, and this sampling tool cost is higher, volume large and bulky, under adopt process
In can only gather sample once each time, occur during repeated sampling and remain in water sample in sampler inner wall to next time
The interference contamination phenomenon of water sample, will also result in certain error.Currently it is directed to earth's surface water isotope, water chemistry layered water sample is adopted
Acquisition means do not occur also, it is therefore desirable to utility model it is a kind of can stratified sampling surface water device, solve river water layering collect with
And the problem of vaporization prevention, reduction other factors interference.
The content of the invention
The utility model is in order to solve vaporization prevention during river water layering is collected and collected, reduce extraneous water body and gas
The problem of being disturbed etc. key element, there is provided a kind of earth's surface water isotope, water chemistry layered water sample harvester.
