Abstract
The utility model relates to a modular earth pillar eluviation experimental apparatus includes: first module (1), the second module (2), third module (3) and outer wall, first module (1) forms a whole with the outer wall, the lower part of first module (1) is the infundibulate, the upper portion of first module (1) is the cylinder, the upper end screw thread of first module (1) forms the internal surface at this cylinder, the second module (2) and the structure of third module (3) is the same and be the cylinder that has upper end screw thread and lower extreme screw thread, the second module (2) and third module (3) the lower extreme screw thread is located the surface of this cylinder respectively, the second module (2) and third module (3) the upper end screw thread is located this cylinder internal surface respectively. Through threaded connection between every module of the device, the modular earth pillar eluviation experimental apparatus of this application has simple structure, convenient operation, characteristics that the durability is good to can make up wantonly according to experiment demand length.
Description
Technical field
The present invention relates to a kind of native fish experimental provision, in particular, a kind of modular native fish experimental provision.
Background technology
Along with rapid development of economy, China's soil is polluted by various polluter, and these pollutant probably migrate to subsoil water, affects the health of the people.Native fish experiment is a kind of effective research means, can the most objectively react soil to the adsorption capacity of polluter and retarded capability, draw pollutant Transport in soil.At present, the earth pillar of laboratory drenches experimental provision, and earth pillar cylinder is that an elongated cylinder is overall.After experiment terminates, the soil in earth pillar to be taken out in the layering of the upper end of earth pillar, record the pollutant content at different depth.Due to earth pillar cylindrical elongate, the cleaning that the earth that fetches earth is difficult in operation and earth pillar cylinder is not easy to carry out.If earth pillar sample different in size needed for different experiments, must additionally purchase earth pillar.
Utility model content
The problem that the application exists for above-mentioned prior art, the technical scheme of employing is:
A kind of modular native fish experimental provision, wherein, including: the first module, the second module, three module and outer wall, described first module forms an entirety with outer wall, the bottom of described first module is infundibulate, the top of described first module is cylinder, and the threaded upper ends of described first module is formed at this cylindrical inner surface；Described second module is identical with the structure of described three module and is and has threaded upper ends and the cylinder of lower end screw thread, the described lower end screw thread of described second module and described three module lays respectively at this cylindrical outer surface, and the described threaded upper ends of described second module and described three module lays respectively at this cylindrical inner surface；
Further, described first module, described second module and described three module can be the most threaded；
Further, according to experiment length demand, it is possible to continue to connect the add-on module as described second module and described three module on three module；
Further, according to experiment length demand, it is possible to described second module and described three module are removed；
Further, the damaged surface of earth pillar indicates rule.
This device will not be affected by prior art discussed above and be had simple in construction, easy to operate, practical advantage.
Accompanying drawing explanation
Fig. 1 shows the front view of the application modular native fish experimental provision；
Fig. 2 shows the sectional view of the application modular native fish experimental provision.
Detailed description of the invention
By purely providing indefinite example, with reference, this novel further characteristic and advantage will become apparent from, wherein:
With reference to Fig. 1, a kind of modular native fish experimental provision, including first module the 1, second module 2, three module 3.Described first module 1 and the second module 2 and three module 3 are threaded connection, and can continue to connect and the second module, module that three module is the same on the basis of three module 3 with experimental length demand.
Work process of the present utility model is as follows: when first the tapering body portion in the first module 1 fills the quartz sand of required specification to prevent draining, soil is flushed away, then continue to banket on quartz sand, when soil height is close to screw thread, second module 2 is received in the first module 1, then proceed to banket, when soil height is close to the second module 2 threaded upper ends, three module 3 is connected in the second module 2, until being filled to soil test desired height.After experiment completes, fetch earth earth with experimental tool, when the soil in module 3 all takes, take off three module 3, then continuing to take the soil in the second module 2, the soil in the second module 2 takes off the second module 2 when all taking, finally take the soil in the first module 1.If experiment earth pillar length requirement is 70cm, then need to continue connection and the second module 2, module that three module 3 structure is the same on the basis of as shown in Figure 1.
Claims (5)
1. a modular native fish experimental provision, it is characterized in that, including: the first module (1), the second module (2), three module (3) and outer wall, described first module (1) forms an entirety with outer wall, the bottom of described first module (1) is infundibulate, the top of described first module (1) is cylinder, and the threaded upper ends of described first module (1) is formed at this cylindrical inner surface；Described second module (2) is identical with the structure of described three module (3) and is and has threaded upper ends and the cylinder of lower end screw thread, the described lower end screw thread of described second module (2) and described three module (3) lays respectively at this cylindrical outer surface, and the described threaded upper ends of described second module (2) and described three module (3) lays respectively at this cylindrical inner surface.
