Stating guiding empennage includes at least two bent wing-like blades, and the song wing-like blades are symmetrically fixed on counterweight tube tail portion periphery；It is described
One way stop peturn valve is equipped in core cutter；When sampling, open check-valves by pressure, when lifting reversely pushes check-valves to make it
Closure prevents deposit from sampling bottom of the tube outflow.
The one way stop peturn valve is made of multiple Elastic Arch pieces of gathering.
The one way stop peturn valve is made of biplate hinge, and hinge axis is fixed on core cutter inner wall, and hinge back is equipped with
The elastomeric element for preventing biplate hinge from fitting together completely.Two hinges open certain angle under the action of elastomeric element,
It is easily resetted by hinge when jacking force, closes nozzle, sample is prevented to be lost.
The one way stop peturn valve is made of at least three valve sheet, and the connecting pin of valve sheet is arch, at the top of arch with adopt
Sample drill bit inner wall is hinged, and valve sheet back is equipped with the elastomeric element for preventing it from fitting together completely with core cutter inner wall.
The one way stop peturn valve is made of at least three valve sheet, and the junction of valve sheet and core cutter inner wall, which is equipped with, to be turned round
Spring.
Preferably, the valve sheet is 4.
Preferably, the bent wing-like blades are 3 or 4.
The counterweight tube periphery is fixed with cone-shaped metal clump weight, and conical head is directed toward core cutter direction.Counterweight tube is borrowed
Own wt is helped, deposit layer is inserted into certain speed, and reach certain depth, it is ensured that deposit collection capacity.
Graduation mark is indicated in the sampling inner tube.
Preferably, the core cutter, sampling outer tube, counterweight tube and guiding empennage are made of rush-resisting material, in fact
Existing mode includes but is not limited to plate one layer of rust-preventing film in outer wall, prevents from getting rusty in long-term use process.
Sampling inner tube is special substance, can avoid organic matter etc. and is adhered on tube wall, while prevented also from sampling pipe
Heavy metal enters in adopted deposit, the liner be it is disposable, avoid the mutual pollution of different deposits；It samples in inner tube
Indicate graduation mark, it may be determined that the thickness of adopted undisturbed sediment；When subsequent samples, sampling inner tube is directly released, adopted dirt can be made
Mud keeps original state, and does not destroy sludge layer structure.
Compared with prior art, the utility model has the advantages that
(1) for the utility model sampler during water body is downward, guiding empennage keeps sampler in a vertical state, and
Sampling pipe rotation is driven to sink, core cutter is pricked downward with certain speed straight down into deposit layer, and deposit squeezes at this time
Check-valves is strutted, after the completion of sampling, deposit has outflow trend, generates deboost, is closed check-valves, prevents deposition logistics
Out.
(2) the utility model has big sampling depth, survivable deposit physical structure and sequence structure, and structure
Make it is simple, it is easy to operate the advantages that.
