Abstract
The utility model discloses a micro - interstitial water collection pipe of ecological experiment deposit, it is including the experiment container that contains water and deposit, an experiment container outside connection N sampling pipe, N >= 1, it is sealed that the pot clay end is passed through to one end that the sampling pipe inserted the experiment container, and it is sealed that the other end passes through the rubber buffer, L shape breather pipe has been inserted on rubber buffer upper portion, and the bleeder line has been inserted to the lower part, placed the floater in the breather pipe, led to first mouth of pipe diameter of air tube outlet and diminish gradually to the diameter that is less than the floater. It is real the utility model discloses but the outer layering of well experiment container sets up a plurality of sampling pipes, can sample to the different deposit of closely knit degree, can realize the higher deposit interstitial water layering sampling of accuracy. The utility model discloses the sampling pipe volume is less, and the biggest collection water yield is 5 -10ml, therefore can realize the collection of micro - interstitial water.
Description
Technical field
The utility model belongs to a kind of device that Ecology experimental technique field medium-scale Ecology experiment sediment interstitial water gathers, and is specifically related to one and tests sedimental slight clearance hydromining collector for Ecology.
Background technology
In recent years, along with the continuous deterioration of water ecosystem, Water Ecological Recovery experiment is being strengthened in recent years day by day.But, in the experiment of lab simulation water ecosystem, lack a kind of device being used for gathering sediment slight clearance water sample specially.Mostly be the method for sampling adopted when adopting field work at present, specific as follows: centrifuge method, milling process, dialysis, air-breathing draw liquid method and capillary tube technique.But there is following defect in said apparatus and method: 1) large to sediment disturbance, all collectors all need harvester to be inserted among sediment, or directly collection bed mud has larger impact to bed mud environment, has larger destruction to bed mud morphological integrity; 2) destroy greatly to hydrophyte root system, harvester at the sedimental root system destroying plant in sediment of insertion simultaneously, thus have impact on the growth of plant; 3) sampling precision is not high, cannot realize the collection of slight clearance water.
Utility model content
For problems of the prior art, the utility model provides one and tests sedimental slight clearance hydromining collector for Ecology.This collection tube and experiment container is melting sealed is integrated, avoids because of rocking of bringing of sampling and the disturbance to water body and bed mud.The easy portable of this device, can realize the bed mud Interstitial Water stratified sampling that degree of accuracy is higher.
The utility model is by the following technical solutions:
A kind of for ecological experiment sedimental slight clearance hydromining collector, it comprises the experiment container filling water and sediment, it is characterized in that, connects N number of sampling pipe, N >=1 outside described experiment container; One end of described sampling pipe loading test container is sealed by pot clay end, and the other end passes through rubber stopper seal; Described rubber plug top is inserted with L shape snorkel, and bottom is inserted with ajutage; Be placed with ball float in described snorkel, venting tube outlet first half nozzle diameter diminishes gradually to the diameter being less than ball float.
Described snorkel sidewall is also provided with scale, and its exit is provided with breather valve.
Described ajutage exit is provided with water drain valve.
The total amount that described sampling pipe holds Interstitial Water is 5-10mL.
Described sampling pipe and experiment container are plastic material, and the two adopts melting sealed connection.
The beneficial effects of the utility model are: the easy portable of device, has stronger operability; The stratified sampling of slight clearance water can be carried out to experiment sediment, and by being arranged on scale in airway wall and built-in ball float display Interstitial Water capacity of adopting; Sediment interstitial water can be gathered by undisturbed; Experiment aquatic plants growth is had no effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1 is experiment container, and 2 is sampling pipe, and 3 is pot clay end, and 4 is water drain valve, and 5 is ball float, and 6 is breather valve, and 7 is ajutage, and 8 is snorkel, and 9 is rubber plug.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of for ecological experiment sedimental slight clearance hydromining collector, it comprises the experiment container 1 filling water and sediment, it is characterized in that, connects N number of sampling pipe 2, N >=1 outside described experiment container 1; One end of described sampling pipe 2 loading test container 1 is sealed by pot clay end 3, and the other end is sealed by rubber plug 9; Described rubber plug 9 top is inserted with L shape snorkel 8, and bottom is inserted with ajutage 7; Be placed with ball float 5 in described snorkel 8, snorkel 8 exports first half nozzle diameter and diminishes gradually to the diameter being less than ball float 5.
Described snorkel 8 sidewall is also provided with scale, and its exit is provided with breather valve 6.
Described ajutage 7 exit is provided with water drain valve 4.
The total amount that described sampling pipe 2 holds Interstitial Water is 5-10mL.
Described sampling pipe 2 is plastic material with experiment container 1, and the two adopts melting sealed connection.
The using method of above-mentioned collection tube is as follows:
First, open L shape snorkel top gas valve, close the valve of ajutage, seeped water toward collection tube inside by pot clay end in collection tube, along with the floating continuous shift position of ball float in the infiltration L shape snorkel of Interstitial Water, can learn when ball float moves to graduation position in snorkel and adopt the water yield in sampling pipe, when ball float move to snorkel nozzle diameter be less than floating ball diameter position time, venting tube outlet blocks and shuts by ball float, Interstitial Water will be no longer included in collection tube infiltrate, now turn off L shape snorkel top breather valve for no longer including air current flow inside and outside guaranteeing, pin the Interstitial Water be deep in collection tube.Then Interstitial Water is collected, and open the water drain valve of L shape snorkel top breather valve and ajutage, Interstitial Water flows out automatically from ajutage, closes ajutage valve after current terminate, and opens L shape snorkel top gas valve and carries out sample collection next time.
Experimental needs, layering can arrange multiple sampling pipe outside experiment container, can sample for the sediment that packing is different, can realize the sediment interstitial water stratified sampling that degree of accuracy is higher.The utility model sampling pipe small volume, the maximum collection water yield is 5-10mL, thus can realize the collection of slight clearance water.
