Description
Technical field
The invention belongs to the waters such as river course, lake bed mud sampling equipment, be specifically related to a kind of novel sediment sampler.
Background technology
River course, bottom mud in lake, once become the presence of pollution sources of water body after being polluted, affect water body environment for a long time.In order to contaminant transportation, conversion and accumulation before studying water body and bed mud, and the impact on water body environment, must from drilling through different depth undisturbed sediment sample under water, for detecting wherein pollutant load.
At present, domestic and international existing one-tenth mud sampling equipment mainly comprises grab simpler, drills through formula and column extraction type.
Mainly there are the following problems in sampling process for traditional column extraction type:
1. sample the bed mud that obtains owing to there being relatively large water, sample accommodating is large, not portable, particularly when sampling quantity is large time.And easy muddy water mixing in transportation, after mixing, some sample dehydration difficulty can strengthen.In addition, water is the medium that many reactions occur, and in transportation, have the character of similar concussion reactor, and can accelerate some composition in bed mud is discharged in water layer, causes prohibited data detection.
2. in sampling process, easily occur that substrate sludge extracting difficulty or bed mud leak.
3. common sediment sampler can not regulate the capacity gathering bed mud, and adaptability is extensive not.
Summary of the invention
For the problems referred to above, the present invention aims to provide one and bed mud can be prevented in sampling process to leak, can preliminary hydro-extraction and the novel sediment sampler of adjustable collection capacity.
The technical scheme that the present invention deals with problems is: a kind of novel sediment sampler, comprise column sampling pipe and be fixedly mounted on the link at column sampling pipe top, described column sampling pipe top is provided with flow-guiding mouth, this flow-guiding mouth and column sampling pipe inner space, dismountablely bottom column sampling pipe be provided with sampling head.
Described sampling head is the tubular structure of open bottom end, its top is radially provided with into mud plate, enters mud plate has at least one to enter mud hole, each enter mud hole place be all fixed with shell fragment, this shell fragment, by can being backed down after lifting force, resilience also can will enter the complete capping in mud hole after cancelling thrust.
Coordinate in the inner chamber of described column sampling pipe and piston head is installed, piston head has vertically at least one through limbers, corresponding position, limbers, piston head lower end has draw-in groove, be provided with porous in draw-in groove but stop the filter disc that bed mud passes through, relative both sides, piston head top are installed with piston push rod.
Described link has the through hole C that piston push rod can be allowed to pass, and link top side detachable be connected with connecting link, connecting link upper end is dismountable is connected with handle.
On described connecting link, radial direction has through hole A, and piston push rod upper end radial direction has through hole B, and through hole A and through hole B aims at and inserts gim peg, and piston push rod is connected with connecting link.
Concrete, described shell fragment comprises the sheet rubber be fixed on into edge, mud hole, and the sheet rubber lower surface entering mud bore region in correspondence is fixedly pasted with sheet metal.
Preferably, described connecting link vertically interval has multiple radial direction through hole A, the through hole B on piston push rod align different radial direction through hole A insert gim peg, piston head can be made to be positioned at differing heights position.As required, the bed mud capacity gathered can be regulated easily.
Have additional extension rod between described connecting link and handle, extension rod upper end and handle removably connect, and lower end and connecting link upper end removably connect.
Described sampling head and column sampling pipe, link and connecting link, connecting link and extension rod, to be all threaded connection between extension rod and handle.
For convenience of observing in gatherer process, described column sampling pipe is PVC transparent pipe.And its outside surface is provided with scale.
Further, described connecting link vertically interval has multiple radial direction through hole A, and spacing distance between multiple radial direction through hole A is identical with the unit scales of column sampling pipe outside surface.
For reducing the resistance in sampling thief insertion bed mud process, described sampling head lower circumferential edge is provided with the chamfering of cutting sth. askew, and radial direction is provided with the semi arch edge of a knife along sampling head central axis symmetry.
Sampling head in use, first, is connected on column sampling pipe lower end and screws by sediment sampler of the present invention, is loaded by piston head in column sampling pipe, with bolt, link is fixed on column sampling pipe top.Then, connecting link is connected on link; According to the depth of water, increase and decrease extension rod number, and extension rod is connected with connecting link and handle.According to sample requirement adjustment piston head height, then gim peg is inserted in through hole A and through hole B, make piston head be fixed to relevant position.
After assembling sampling thief, sampling thief is vertically put into water on bank by user, after touching bed mud, applies pressure by handle, orders about sampling thief and gos deep into bed mud.In process, the shell fragment entered on mud plate is pushed open by the water entered between mud plate and bed mud, and through the limbers on piston head, flows out from column sampling pipe top.When bed mud touches into mud plate, the bed mud in sampling head is sediments.Along with the continuation of sampling thief is goed deep into, bed mud passes through to enter column sampling pipe into the mud hole of entering of mud plate.When in column sampling pipe, bed mud rises to piston head height, bed mud cannot pass through, and when sampling thief continues to sink, the bed mud in column sampling pipe no longer increases.
When mentioning handle, in the process that sampling thief rises, shell fragment is subject to the downward pressure of bed mud in column sampling pipe, and seal into mud hole, bed mud can not be revealed.Fast lifting sampling thief, to bank, pulls down gim peg, connecting link, link.Then be again plugged on piston push rod by gim peg, and push downwards, the moisture in bed mud is forced into the cavity above piston head through limbers, poured out by water afterwards from flow-guiding mouth, and this process is preliminary hydro-extraction.
Finally take off sampling head, with piston, bed mud is released transfer, use clean water sampling thief, and change filter disc according to demand.
The invention has the beneficial effects as follows:
1., because this sediment sampler has the function of preliminary hydro-extraction, the bed mud sample accommodating collected is reduced, easily carries; Particularly for soft bed mud sample, after preliminary hydro-extraction, sample moisture obviously reduces, and reduces the difficulty of follow-up dehydration, it also avoid the mixing of muddy water in sample transport process and the situation of prohibited data detection that causes occurs.
2., owing to devising elastic piece structure, in sampling withdrawal process, enter mud hole by shutoff, bed mud can not leak.
3. the design of gim peg and through hole A, B makes the piston head height adjustable of this sampling thief, as required, can regulate the bed mud capacity gathered easily, have adaptability widely.
4. this collector easy accessibility, uses rear easy to clean.
