The utility model discloses a set up the osmotic membrane on the sampling pipe of co-altitude not, can carry out non-destructive sampling many times, realize soluble material's dynamic exchange, can combine together indoor culture experiment and rear end detecting instrument, realize the direct detection of sample, not only can acquire the clearance water parameter but also can acquire other soluble material parameters, but real-time dynamic detection can realize the monitoring to soluble material gradient diffusion in the deposit.
Description
Technical Field
The utility model belongs to the technical field of the sampling, especially, relate to a deposit clearance moisture layering developments sampling device.
Background
At present, the collection of the water in the gaps of the sediments is mainly destructive sampling, namely, the sediments are collected and then centrifuged to obtain a sample. This results in:
1) on one hand, the collection of the sample means the complete destruction of the original deposit; centrifugation on the other hand requires more samples and requires mixing of samples at different sedimentation periods-studies have found that 1cm of sediment may result from more than 3 years of sedimentation.
2) The sediment interstitial water obtained in the prior art usually contains more particles, and needs to be treated by steps such as filtration and the like, so that the operation is complicated.
3) The study of water-sediment interfaces is limited in time and difficult to observe stably for a long period of time.
Therefore, there is a need to provide a new sediment gap water stratification dynamic sampling device to solve the above technical problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sediment gap water stratification dynamic sampling device in order to solve the above problems.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
a sediment gap water layering dynamic sampling device comprises a plurality of sampling pipes, wherein the sampling pipes are provided with penetration holes, penetration membranes are arranged in the penetration holes, one ends of the sampling pipes are closed, the other ends of the sampling pipes are opened, and one ends of the sampling pipes, close to the openings, are provided with water stop clamps and peristaltic pumps;
a clamping plate is arranged between two adjacent sampling pipes.
As the utility model discloses a further optimization scheme, the sampling pipe with splint are the plastics material.
As a further preferred aspect of the present invention, the clamping plate is a retractable clamping plate, which can be right to two of the clamping plate top and bottom sides the distance between the sampling tubes is adjusted.
The beneficial effects of the utility model reside in that:
the utility model discloses a set up the osmotic membrane on the sampling pipe of co-altitude not, can carry out non-destructive sampling many times, realize soluble material's dynamic exchange, can combine together indoor culture experiment and rear end detecting instrument, realize the direct detection of sample, not only can acquire the clearance water parameter but also can acquire other soluble material parameters, but real-time dynamic detection can realize the monitoring to soluble material gradient diffusion in the deposit.

Detailed Description
The present application will now be described in further detail with reference to the drawings, and it should be noted that the following detailed description is given for purposes of illustration only and should not be construed as limiting the scope of the present application, as these numerous insubstantial modifications and variations can be made by those skilled in the art based on the teachings of the present application.
Example 1
As shown in fig. 1-3, a sediment gap water stratification dynamic sampling device includes a plurality of sampling tubes 1, a penetration hole 3 is formed in each sampling tube 1, a penetration membrane 4 is arranged in each penetration hole 3, the aperture of each penetration membrane 4 can be selected according to the requirement, one end of each sampling tube 1 is a closed end, the other end of each sampling tube 1 is an open end, and a water stop clamp 5 and a peristaltic pump 6 are arranged at one end of each sampling tube 1 close to the open end;
two adjacent be provided with splint 2 between sampling pipe 1, splint 2 is scalable splint, can be right two of splint 2 top side and bottom side distance between the sampling pipe 1 is adjusted.
The sampling tube 1 and the clamping plate 2 are made of plastic materials, and metal is not used for preventing the metal from reacting with the sediment.
The utility model provides a sediment clearance moisture layering developments sampling device's theory of operation as follows:
when the device is used, after the device is inserted into sediment (or soil), high-purity water is filled into the sampling tube 1, then the water stop clamp 5 is closed, the device is kept still for a period of time, (the exchange time is determined according to an object to be researched), the water stop clamp 5 is opened, the peristaltic pump 6 is started for sampling, sediment gap water enters the sampling tube 1 through the permeable membrane 4, dynamic exchange of soluble substances is achieved, and nondestructive sampling is achieved.
The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention.
