Technical field
The utility model relates to precipitation and gathers measuring instrument, specifically a kind of instrument that utilizes former state water seal to deposit into row precipitation isotope sample collection and measurement.
Technical background
Isotope technology can be the research of River Basin Hydrology rule, the identification of hydrological model structure and parameter etc. details is provided, and can effectively avoid the problem of dtmf distortion DTMF to natural situation simulation, obtains real hydrology rule.Formation, flow path, age, supply elevation, source and composition ratio etc. that isotope technology can be Study of The Underground water provide direct information, for the understanding recharge of ground water and renewal Changing Pattern provide important evidence.In the quantitative and qualitative analysis research of the each link of water circulation, the research of many hydrology problems such as isotope is applied to distinguishing that Regional Precipitation moisture source, precipitation discharge curve are cut apart, surface water and groundwater conversion, footpath flow path discriminating, residence time and Hydrology feature.And can be applied to the aspect researchs such as the impact on hydrologic process such as paleoclimate research, leakage of dam foundation, plant water use efficiency variance and change in time and space and precipitation/snow, ice-melt, evaporation, arid, elevation, landform.Isotope technology has played unique effect in addressing the above problem.
Isotopic mensuration precision is had relatively high expectations to the sampling work of sample, and sampleman is done success or not and determined to a certain extent isotopic mensuration precision.Most of isotope fractionations are in water sampling, transport, preservation process, cause via evaporation or diffusion, and wherein sampling work is major influence factors.Isotope sample sampling key is promptness and the sealing problem of sample, and especially, concerning precipitation, sampling work is just more difficult.Sampling job requirement gathers in the shortest time after precipitation, if long-time sudden and violent leakage of sample is subject to Influence of Evaporation, will have a strong impact on the isotopic composition of water sample, and this sample just can not be used for isotope test in this case.Therefore be badly in need of providing a kind of precipitation isotope sample collecting apparatus of science.
Utility model content
The problems such as the utility model is high to sampling job requirement for isotope assay precision, precipitation sampling difficulty, a kind of precipitation isotope sample collecting apparatus is provided, when this device should be guaranteed water sampling in the wild, isotopic composition does not produce fractionation, thereby obtains reliable isotopic data.
A kind of precipitation isotope sample collection measuring instrument that the utility model provides, comprise V-arrangement funnel, V-arrangement funnel is communicated with gathering barrel by flexible pipe, U-bend, U-bend is fixed on sealed rubber plug on the mouth of gathering barrel, gathering barrel is fixed on fixed mount with annular rubber band, fixed mount is connected on shell, and sealed rubber plug is provided with kapillary, and the kapillary top mouth of pipe arranges movable sealing lid; The bottom of gathering barrel is provided with valve and outlet; On gathering barrel, be carved with metering scale; Shell is provided with door that can switch.
The bottom of described shell can arrange three fixing feet, makes to gather measuring instrument installation and places more stable.
Described shell and door are flexibly connected by the first loose-leaf and the second loose-leaf; On described door, snap close is set.
Described cover top portion can be installed filter screen.
Precipitation isotope sample collection measuring instrument of the present utility model, can move automatically according to design and technical requirement, gathers precipitation isotope analysis sample.Precipitation sample utilizes water seal to be sealed in and gathers in measuring instrument, can avoid sample affected by evaporation, distillation, recrystallization, thawing etc. and change initial isotopics, and sampling precision is high, and has promptness, rapidity and convenience.This measuring instrument also can be used as quantity of precipitation automatic measuring unit and records in time quantity of precipitation etc.

Embodiment
A kind of precipitation isotope sample collection measuring instrument as Figure 1-3, comprise V-arrangement funnel 5, V-arrangement funnel 5 is communicated with gathering barrel 8 by flexible pipe 6, U-bend 7, U-bend 7 use sealed rubber plugs 2 are fixed on the mouth of gathering barrel 8, the annular rubber band 4 of gathering barrel 8 use is fixed on fixed mount 3, fixed mount 3 is connected on shell 15, and sealed rubber plug 2 is provided with kapillary 1, and the kapillary 1 top mouth of pipe arranges movable sealing lid 18; The bottom of gathering barrel 8 is provided with valve 9 and outlet 10; On gathering barrel 8, be carved with metering scale; Shell 15 is provided with door 16 that can switch.The bottom of shell 15 is provided with three fixing feet 14.Shell 15 and door 16 are flexibly connected by the first loose-leaf 11 and the second loose-leaf 13; On door 16, snap close 12 is set.At collection measuring instrument top, filter screen 17 is installed, in order to prevent that the objects such as leaf from falling into funnel impact and collecting precipitation.
Described U-bend 7 is a U-shaped glass component, and it can carry out water shut off treatment to sample, and precipitation will seal gathered water sample at U-bend place.
Described kapillary 1, V-arrangement funnel 5 and gathering barrel 8 are glass component or plastic member.
The kapillary 1 that sealed rubber plug 2 is provided with, it can ensure the unimpeded of conduit precipitation current, the movable sealing lid 18 that kapillary 1 outlet arranges can be according to the automatic opening and closing of fault of gathering barrel 8 inner and outer air pressure pressure reduction, is conducive to automatically gather in time precipitation sealing in time.
Gather all junctions of measuring instrument and be tightly connected (as adopted rubber plug etc.).Gathering barrel 8 wherein can, with aluminium foil or polystyrene foam parcel, can be avoided along the evaporation of bucket wall like this.
Gather measuring instrument in use, by the fixing feet outside shell, whole device is fixed on to the spaciousness place away from buildings and trees.Sampler around basis is firm, and whole device is fixed on supporting surface, makes the opening of sampler in level, should be greater than 1m from the height of supporting surface, and when avoiding quantity of precipitation large, muddy water is splashed in sampling thief screen pack.
In device upper end, filter screen 17 is installed, precipitation, by filter screen, through V-arrangement funnel 5, enters U-bend 7.To retain precipitation at sampler U-bend place and form water seal (water surface seals up bent tube section).In the time that U-bend 7 places are full of water, water sample continues overflow, utilizes the pressure reduction in conduit, makes the water of water-sealing part start to enter gathering barrel 8, and in this case, sampling work starts automatically, and gathering barrel starts to collect precipitation sample.Gather all sealings of measuring instrument with encapsulant and be designed to the pattern that can stop moisture evaporation and spread, to avoid evaporation and diffusion loss, thereby reach the object that improves sampling precision.
After precipitation stops, immediately sample in sampler being sealed up for safekeeping.Seal process should be rapid in time, avoids sample to contact with air, in order to avoid evaporation produces fractionation.Gathering barrel also can carry out the mensuration of quantity of precipitation.
Gather measuring instrument and answer periodic maintenance, comprise and clean water seal conduit, gathering barrel and screen pack.When cleaning, first take off screen pack, gathering barrel and water seal conduit, after with high purity water, water seal conduit gathering barrel and screen pack being cleaned, put back in device, connect conduit, guarantee the sealing of pipeline.
