The utility model has the advantages that, quick depthkeeping sampling can prevent water sample from mixing, and be detection water and soil pollution distribution situation
Favourable Data safeguard is provided, and the device simple structure, be easy to carry, with use value very high.
Brief description of the drawings
Fig. 1 is the structural representation of piston drawing-in type ground water fixed depth harvester in the utility model.
Specific embodiment
Feature of the present utility model and other correlated characteristics are made further specifically by embodiment below in conjunction with accompanying drawing
It is bright, in order to the understanding of technical staff of the same trade：
Such as Fig. 1,1-7 is marked to be respectively in figure：It is check-valves 1, piston 2, water intaking sleeve pipe 3, exhaust tube 4, upper plug head 5, lower stifled
First 6, baffle plate 7.
Embodiment：As shown in figure 1, the present embodiment is specifically related to a kind of piston drawing-in type ground water fixed depth harvester, should
Sampling apparatus sets piston 2 and bottom setting check-valves 1 by being arranged in water intaking sleeve pipe 3, and depthkeeping is completed using the absorption of piston 2
Water intaking.
As shown in figure 1, the depthkeeping harvester in the present embodiment includes water intaking sleeve pipe 3 and coupled exhaust tube
4, there are dial markings on the exhaust tube 4, mouth of pipe one end of exhaust tube 4 is accessed from the top of water intaking sleeve 3, exhaust tube 4 with
The junction of water intaking sleeve 3 uses rubber seal, and the other end is used for external pressure draw-out device, by the exhaust tube 4
Scale can make a reservation for depth of fetching water；Piston 2 is set in water intaking sleeve pipe 3, and the piston 2 can be in the case where water intaking sleeve pipe 3 inwall coordinates
Move up and down, upper plug head 5 and lower end cap 6 are respectively arranged with the upper and lower surface of piston 2, upper plug head 5 is disposed thereon
The underface of the mouth of pipe of square exhaust tube 4, and size is adapted with the size of the above-mentioned mouth of pipe, when piston 2 rises to water intaking sleeve pipe 3 most
During top, can block the mouth of pipe of exhaust tube 4, prevent current from falling in the pressure extracting device being sucked into earth's surface；Intake pipe 3 it is interior
Portion is provided with baffle plate 7, and the baffle plate 7 is located at the lower section of piston 2, and the mouth of a river was offered on the middle part of baffle plate 7；Above-mentioned piston 2
On lower end cap 6 be located at the baffle plate 7 on cross the mouth of a river surface, and the size of lower end cap 6 and it is above-mentioned cross the mouth of a river size
It is adapted, before the sampling apparatus is not actuated, when above-mentioned piston 2 is located at bottom, the lower end cap 6 is used to block the mouth of a river, because
This, piston 2 does oscilaltion campaign in the chamber between the top of the lower section of exhaust tube 4 and baffle plate 7, the bottom of sleeve pipe 3 of fetching water
Portion water inlet is provided with check-valves 1, can prevent gathered water sample from leaking outside, and mixing is interacted with underground water.
As shown in figure 1, as follows using the concrete operation step that the harvester in the present embodiment gathers water sample：
（1）Piston drawing-in type ground water fixed depth harvester is closed, piston 2 is now placed in sleeve pipe 3 of fetching water
In baffle plate 7 at, and the mouth of a river of crossing on lower end cap 6 and the baffle plate 7 of piston 2 is in sealed condition；Then above-mentioned piston is taken out
Suction ground water fixed depth harvester is put into monitoring well, and puts into predetermined adopting according to the scale on exhaust tube 4 on the device
Sample depth, starts and the external pressure extracting device of exhaust tube 4；
（2）The pressure of pressure extracting device is adjusted, piston 2 is slowly increased, and 1 dozen, the check-valves under swabbing pressure effect
Open（I.e. check-valves bead is in suspended state）, underground water is flowed slowly into water intaking sleeve pipe 3, until the piston 2 rises to and is located at
At the nozzle position of the exhaust tube 4 of top, the upper plug head 5 on the piston 2 blocks the mouth of pipe completely, should during sampling
Note controlling the speed of piston 2, prevent from for underground water being pumped to earth's surface into pressure extracting device；
（3）Closing presure extracting device, the water intaking sleeve pipe 3 that will be filled with water slowly proposes monitoring well, and the check-valves 1 can returned
Propose process closing（I.e. check-valves bead falls to blocking water inlet）, to prevent gathered water sample from leaking outside, interacted with underground water mixed
Close；
（4）Underground water is gathered into respective sample bottle and sealing preserve according to different groundwater monitoring parameters；
（5）The harvester is cleaned, to other monitoring wells repeat step 1-4, until sampling terminates.
The embodiment has the beneficial effect that：Depthkeeping can quickly sample, prevent the mixing of different soils pollution layer water sample, it is ensured that
The accuracy of gathered data, during the device can prevent underground water from falling to be sucked into pressure extracting device, and return carry during only
Returning valve can be automatically switched off the leakage for preventing gathering water sample, cause the secondary pollution of underground water；Taken with traditional monitoring well underground water
Sample is compared, and the sampling period is shorter.
