Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Accompanying drawing, the present invention is described in further detail.
The invention discloses a kind of multi-channel testing well groundwater sample harvester, including:
N number of sample collecting storage element, for accommodating the N part groundwater sample collected；Described N number of sample collecting stores
The water inlet of unit extends respectively to the correspondence of multi-channel testing well and selectes sampling location；
Flow divider more than one point, is provided with N+1 port, one of them port connect pump, remaining N number of port respectively with described N
The outlet of individual sample collecting storage element connects；
Wherein, outlet and the water inlet of described N number of sample collecting storage element is provided with water check valve respectively；N is for being more than
Positive integer equal to 2.
As preferably, the multi-channel testing well groundwater sample harvester of the present invention, including:
Sampling pump: select according to practical situation and meet the pump required, can directly dock with sample collecting stocking system；
Distribution pipeline system: one point of seven shunting valve body, is provided with 8 ports, and one of them port connects pump, remaining 7 ends
Mouth connects the port of sampling bottle outlet respectively, and the water inlet of sampling bottle extends monitoring well sampling location, the water outlet of each sampling bottle
Mouth and water inlet are equipped with water check valve；Multiple ports of one point of seven flow divider connection sampling bottle outlet are respectively equipped with electronics clamp
Valve.
Sample collecting stocking system: include 7 sampling bottles, the outlet of each sampling bottle passes through conduit and one point of seven flow divider
Connect；The water inlet of each sampling bottle extends monitoring well sampling location by conduit.Sampling bottle is filled with nitrogen, base during water sampling
This does not comes in contact with air.This sample collecting stocking system also includes platen system, by the pin modules coordinated with pressing plate
Realize sampling operation.
Smart circuit control system: electronic clip pipe valve is provided with buzzer.Control system can control the start and stop of pump, tune at any time
The flow velocity of whole pump, control the upper and lower of pressing plate.
As it is shown in figure 1, as a preferred embodiment of the present invention, the platen system of this sample collecting stocking system is main
Being the up and down motion being controlled whole-sample contact pin by line slideway, make pin modules insert in sampling bottle, sample collection completes
After extract contact pin.First module contact pin and top board is fixed on the guide rail slide block 1 on firm banking 7 by frock, and under press
Plate 6 is coupled together by fixing axle 4 (bolt) and top board, carries out pretension by spring 5 in the middle of upper and lower plates.Work as guide rail slide block
1 when moving downward, and top board drives contact pin to move together with lower platen, when sampling bottle is encountered in lower platen 6 motion, and lower platen 6
Due to the restriction stop motion of degree of freedom, top board drives pin modules to continue down to move, and inserts a needle in sampling bottle, now
Moving downward stopping, whole-sample starts, and peristaltic pump operates, and the air extracted out in bottle adopts the water quality sample in well, works as sampling
When water quality sample in Ping reaches requirement, bottle middle water level is higher than contact pin position, is triggered by the conducting between contact pin and stops
Sample command, thus completes water quality sampling.Finally, line slideway moves upward, and drives top board up, but due to spring
Elastic force produced by the deformation of 5 can make lower platen 6 push down sampling bottle to make it to move upward.When contact pin is extracted completely,
Top board drives lower platen 6 overall up, returns to home position, completes whole collecting flowchart.
As it is shown on figure 3, further it can be seen that the structure of this pin modules, including sampling pagoda adapter 10, upper peace
Dress seat 11, lower mounting seat 12 and sampling needle 13.
The invention also discloses and a kind of use above-mentioned multi-channel testing well groundwater sample harvester to carry out the side sampled
Method, comprises the following steps:
1) by conduit, the outlet of multiple sampling bottles is respectively connecting to the port of one point of seven flow divider；
2) respectively at the water inlet installation conduit of sampling bottle, its length is until going deep into continuous multi-channel testing well sampling position
Put；
3) one point of seven flow divider connects a pump；
4), after pump running, water sample is evacuated to sampling bottle from monitoring well, until after the storage of sampling bottle water sample sample is full, electronics clamp
Valve is automatically switched off；
5) close the water check valve of sampling bottle rear and front end, take out sampling bottle cold preservation, detection to be analyzed.
In the method, electronic clip pipe valve is met when water is automatically switched off and is sounded a buzzer.
