Description
Technical field
The utility model belongs to sediment layered sampling device, specifically, relates in particular to a kind of sediment layered sampling device for Ecology experiment.
Background technology
Along with day by day increasing the weight of that water pollutes, people are attempting water quality to repair, Ecology experimental method was being strengthened in recent years day by day, yet the device that lacks a kind of effective collection sediment sample in the indoor simulation of carrying out Ecology experiment, existing device mostly is the sampling thief that field work is used, as heavy hammer type mud sampling device, clip type deposit sampler, manual rotation type column shaped sampling thief etc., it is heavy that the sampling thief of these types seems in the use of indoor Ecology simulated experiment, and can not realize preferably stratified sampling, and be easy to cause bed mud leak and can not complete sampling in sediment packing compared with little in the situation that.Moreover this general volume of collector that is applicable to field work is larger, sampling diameter is larger, cannot sample to the sediment under the simulated environment in laboratory.
In view of the foregoing, the in the situation that of Ecology simulated experiment, need a kind of small and exquisite easy, workable, sediment layered sampling device that sampling precision is high.
Summary of the invention
The purpose of this utility model is to provide a kind of sediment layered sampling device for Ecology experiment, and it has small and exquisite easy, workable, is suitable for the accurate stratified sampling of the Ecology sediment layering under simulated environment in laboratory.
The utility model is achieved through the following technical solutions:
The sediment layered sampling device for Ecology experiment described in the utility model, comprise sampling thief, described sampling thief is under shed structure, the top of sampling thief has sealing water delivering orifice, on sampling thief, be also provided with T-shaped structure first, T-shaped structure second, described T-shaped structure first comprises T-shaped connecting link first, piston first, and described T-shaped structure second comprises T-shaped connecting link second, piston second, and described piston second is provided with soft barrier film; Described T-shaped connecting link first is hollow structure, is provided with T-shaped connecting link second in it; Described piston first, piston second is provided with through hole first, through hole second.
Say further, the sampling thief described in the utility model is preferably ∩ type structure.
Say further, the sampling thief described in the utility model adopts transparent material to make, and described T-shaped connecting link first is provided with scale.
Say further, the T-shaped connecting link first described in the utility model, to have the length of T-shaped connecting link second be 1300mm, and the length of sampling thief is 1000mm, and the diameter of piston first and piston second is that 50mm, thickness are 5mm, and the diameter of through hole first and through hole second is 2.5mm.
Compared with prior art, the utlity model has following beneficial effect:
1, the easy portable of the utility model has stronger operability in laboratory, can sample for the different sediment of packing;
2, the utility model can be realized the sediment stratified sampling that degree of accuracy is higher, and the sample gathering is realized to effective Accurate Segmentation, and little to the disturbance of S & W body in the process of using;
3, the utility model low cost of manufacture, can realize scale, the production of batch production, has the market application foreground of penetration and promotion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the sampling thief in Fig. 1;
Fig. 3 is piston first in the utility model and the structural representation of piston second.
In figure: 1, sealing water delivering orifice; 2, T-shaped connecting link first; 3, piston first; 4, T-shaped connecting link second; 5, piston second; 6, soft barrier film; 7, through hole first; 8, through hole second; 9, sampling thief.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1: a kind of sediment layered sampling device for Ecology experiment, comprise sampling thief, described sampling thief 9 is to be the ∩ type structure of transparent material, at the top of sampling thief 9, have sealing water delivering orifice 1, on sampling thief 9, be also provided with T-shaped structure first, T-shaped structure second, described T-shaped structure first comprises T-shaped connecting link first 2, piston first 3, and described T-shaped structure second comprises T-shaped connecting link second 4, piston second 5, and described piston second 5 is provided with soft barrier film 6; Described T-shaped connecting link first 2 is hollow structure, is provided with T-shaped connecting link second 4 in it; Described piston first 3, piston second 5 are provided with through hole first 7, through hole second 8; Described T-shaped connecting link first 2 is provided with scale; Described T-shaped connecting link first 2, to have the length of T-shaped connecting link second 4 be 1300mm, and the length of sampling thief 9 is 1000mm, and piston first 3 is that 50mm, thickness are 5mm with the diameter of piston second 5, and through hole first 7 is 2.5mm with the diameter of through hole second 8.
In view of above-described embodiment and accompanying drawing, the utility model in use, first need operating personnel's one hand-held sampler 9, the sediment desired height that pulls T-shaped connecting link first 2, T-shaped connecting link second 4 to gather to needs, guarantees that the spacing of the inner institute of sampling thief 9 does not affect thickness of deposits and is advisable.
Sampling thief 9 is vertically inserted in benthal deposit, and to sediment bottom, press down gently T-shaped connecting link second 4, when in pipe, piston second 5 is touched sediment top, stop pressing down, then press down T-shaped connecting link first 2, due to the barrier effect of soft barrier film 6 in piston second 5, water body can only upwards be discharged from the through hole second 8 of piston first 3, when piston first 3 touches soft barrier film 6, stops.
Now will press down together with T-shaped connecting link first 2 holds with T-shaped connecting link second 4, or can determine sediment sampling thickness according to the scale in T-shaped connecting link first 2, and then vertically mention sampling thief 9 and complete sampling process.After having sampled, can promote gently according to the scale in T-shaped connecting link first 2 T-shaped connecting link second 4 by sediment layering release as required.
