Description
Technical field
This disclosure relates to which a kind of gas spring formula depthkeeping pollutes water/gas sampler.
Background technique
Disclosing the information of the background technology part, it is only intended to increase understanding of the overall background of the invention, without certainty
It is considered as recognizing or implying in any form that information composition has become existing skill well known to persons skilled in the art
Art.
The water sampling of underground certain depth is unable to execute-in-place due to located underground, when sampler is lowered into relatively deeply
It place can if reaching predetermined depth water sample not yet and entering sampler by hydrostatic pressing since the hydrostatic pressing of underground is larger
Cause the water sample obtained that cannot represent the water sample of this depth.
Utility model content
For above-mentioned problems of the prior art, a purpose of the disclosure is to provide a kind of gas spring formula depthkeeping
Pollute water/gas sampler.
In order to solve the above technical problems, the technical solution of the disclosure are as follows:
A kind of gas spring formula depthkeeping pollution water/gas sampler, including,
Cylinder is sampled, is hollow cylinder, the top of sampler barrel is connect with air charging system, and the inside of sampler barrel, which is arranged, lives
It fills in, stiff spring, is fixedly connected at the top of one end of stiff spring and sampler barrel, the other end and piston of stiff spring are fixed to be connected
Connect, the first protrusion of the bottom of piston setting, the bottom of sampler barrel is arranged first through hole, the bottom first through hole of sampler barrel it is following
Edge is downwardly extending the protrusion of circular ring shape second, and the top of first through hole is arranged first baffle, the marginal portion of first baffle with
The bottom of sampler barrel is fixedly connected, and several limbers are arranged in first baffle, and the limbers includes being located at first baffle centre bit
The third through-hole on the outside of the second through-hole and the second through-hole set；
First groove, circular ring shape, the side wall of the first groove and the second male cooperation are tightly connected, and the bottom of the first groove is set
Set fourth hole, the intracavitary placement floating ball of the cylindrical empty that the first groove and the second protrusion surround, the second through-hole, fourth hole it is straight
Diameter is less than the diameter of floating ball, and the first protrusion is corresponding with the position of the second through-hole, fourth hole, and the diameter of the second through-hole is greater than the
The height of the diameter of one protrusion, the first protrusion is greater than the height of cylindrical cavity and the difference of floating ball diameter.
The disclosure makes stiff spring and piston downlink by increasing air pressure in sampler barrel, and when downlink portion on earth, first is convex
It rises and pushes down floating ball, floating ball is made to seal fourth hole, sealed during realizing before sampler is lowered at depthkeeping, in order to avoid
The air pressure in sampler barrel is slowly laid down, piston is pulled the effect of the retraction force of spring when reaching at depthkeeping into impurity
Uplink, water sample are slowly entered in sampler barrel by fourth hole, and floating ball stays in always cylindrical cavity due to the blocking of first baffle
It is interior, after the completion of sampling, make pressurization in sampler barrel, hydraulic pressure compressing floater seal lives fourth hole, completes sampling.
The disclosure the utility model has the advantages that
Disclosure cylindrical cavity is made of sampler barrel and the first groove, and sampler barrel and the first groove make to be detachably connected
, directly the first groove and sample after sampler barrel disassembly can be flowed out out of sampler barrel automatically after the completion of sampling, another kind makes
The mode of sample outflow is firmly floating ball to be made to leave fourth hole by fourth hole, and sample flows out automatically from fourth hole.The
A kind of mode is a kind of more effective direct mode；
Disclosure piston is connect with stiff spring, and piston goes downwards to sampler barrel bottom rear haulage spring since retraction force makes to live
Row is the negative pressure space that water sample enters sampler barrel below piston beyond the Great Wall, realizes automatic sampling.
