Abstract
The utility model relates to a meteoric water collecting device comprising a collecting funnel, a connecting nut, a separating sieve plate and a collecting bottle. The meteoric water collecting device is characterized in that the collecting funnel is cask-shaped, the section at the upper side is open, the lower part of the collecting funnel is funnel-shaped, and external threads are arranged on the lower part of the collecting funnel; internal threads are arranged on the bottle opening of the collecting bottle, the collecting funnel is screwed in the collecting bottle, and the two ends of the connecting nut are respectively connected with the collecting funnel at the upper side and the collecting bottle at the lower side; and the separating sieve plate is a circular small plate and is arranged between the collecting funnel and the collecting bottle, the separating sieve plate is embedded in the connecting nut, and minipores are processed on the surface of the separating sieve plate. The meteoric water collecting device provided by the utility model is simple in structure and convenient in operation, so that the meteoric water collecting device is the most ideal container used for collecting meteoric water samples.
Description
Technical field
The utility model relates to a kind of atmospheric precipitation gathering-device of studying trace heavy metals in atmospheric precipitation and designing.
Technical background
In precipitation, the content of heavy metal is very low, generally below ng/g, belongs to the trace scope.Therefore, before carrying out in precipitation heavy metal research, the collection container of precipitation sample is a key link, if collect the precipitation sample collection requirement that the container of precipitation is not suitable for studying trace heavy metal, in collecting this step of precipitation sample, precipitation just might be subject to heavy metal pollution so.Therefore, in collecting Precipitation Process, must adopt suitable collection container.
At present, the precipitation collection container of heavy metal in domestic relevant research precipitation, or adopt vial (Hu Jian etc. 2005), or adopt vinyon case (Bai Li etc., 2010).Yet, in atmospheric precipitation, content of beary metal is general all in the trace scope as previously mentioned, in requirement sampling vessel material, content of beary metal is low, and in collection process, sample is unsuitable contaminated. in above-mentioned sampling container material or content of beary metal is higher, as adopt the vial method, vulnerable to pollution be transferred process after the precipitation collection in as adopting the tygon chest, is not all both the optimal container of collecting the precipitation sample.
Summary of the invention
In order to overcome problems of the prior art, the purpose of this utility model is to provide a kind of atmospheric precipitation gathering-device.Utilize this device, will gather precipitation and flow into receiving flask, and prevent that foreign material from falling into receiving flask, pollute the device of precipitation.
The purpose of this utility model is achieved in that
A kind of atmospheric precipitation gathering-device comprises collection funnel, attaching nut, obstruct sieve plate and receiving flask.It is characterized in that collection funnel is barrel-shaped, upper square section opening, the bottom is funnel-form and external thread is arranged; The receiving flask bottleneck has internal thread, and collection funnel screws in receiving flask, and attaching nut two ends are connected with the below receiving flask with top collection funnel respectively; Intercepting sieve plate is circular platelet, is placed between collection funnel and receiving flask, is embedded in the attaching nut, intercepts on the sieve plate face and has aperture.
Advantage of the present utility model:
1. package unit all parts material is the lower polythene material of content of beary metal or Teflon material.Be made by lower U.S. Nalgene Low Density Polyethylene (LDPE) water-storing bottle of content of beary metal as the collection funnel of topmost and the receiving flask of foot, the built-in obstruct sieve plate of attaching nut is made by high density polyethylene (HDPE) material, the attaching nut is that polytetrafluoroethylmaterial material (PTFE) is made, in the three, content of beary metal is very low, is to carry out the desirable vessel material of trace heavy metal research and comparison in precipitation.
2. thereby obstruct sieve plate minimizing foreign material or other pollutants have been increased in the device to the pollution of rainwater sample.
3. receiving flask directly covers tightly with supporting lid after collecting precipitation, in the subsequent sample transfer process, can prevent the pollution that careless manipulation brings.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further again:
As shown in Figure 1, a kind of atmospheric precipitation gathering-device comprises collection funnel 1, attaching nut 2, intercepts sieve plate 3 and receiving flask 4.Collection funnel 1 is barrel-shaped, upper square section opening, and the bottom is funnel-form and external thread is arranged; Receiving flask 4 is the 1000mLNalgene sample bottle, and bottleneck has internal thread.Collection funnel 1 screws in receiving flask 4, and attaching nut 2 two ends all have internal thread to be connected with the below receiving flask with top collection funnel 1 lower thread respectively to be connected.Intercepting sieve plate 3 is circular platelet, is placed between collection funnel 1 and receiving flask 4, is embedded in attaching nut 2, and above obstruct sieve plate 3,16-diameter being arranged is the aperture of 1mL.
When having precipitation to arrive, connect successively after collection funnel 1, attaching nut 2, obstruct sieve plate 3 and receiving flask 4 is clean through strict pickling, be placed on 1.2 meters supports of roof, rainwater flows directly in collection funnel 1, other foreign material can be blocked sieve plate 3 and be blocked in collection funnel 1, and rainwater can enter in receiving flask 4 by the aperture that intercepts sieve plate 3.Directly receiving flask 4 is taken off after attaching nut 2 unscrews after a precipitation finishes, and transfer to the laboratory after covering tightly with supporting lid and preserve until take out before analyzing.Precipitation is not vulnerable to the pollution that the factors such as operating personnel are brought after collection and in the subsequent transfer process like this.
