Description
Technical field
The utility model is related to sediment sampler technical field, more particularly to a kind of bar holds surface sediment sampler.
Background technology
At present, the surface sediment sampler applied on the market is based on grab type, existing surface sediment sampler
After sampler is proposed from water, due to stress problems, substantial amounts of deposit can be caused to follow water together to flow out, finally must not
Not gathering repeatedly could complete gatherer process, so general acquisition time is long, single acquisition effect is general, sampler quality weight,
It is not readily portable, therefore, it is proposed that a kind of bar holds surface sediment sampler.
The content of the invention
The purpose of this utility model is in order to solve to exist in the prior art sampling efficiency low, and sampling time length lacks
Point, and a kind of bar proposed holds surface sediment sampler.
To achieve these goals, the utility model employs following technical scheme：
A kind of bar holds surface sediment sampler, including sampling pipe and detachable holding bar, and the lower end of the sampling pipe connects
Sampling head is connected to, the outer wall of the sampling pipe is provided with the helical tooth for being easy to sampling pipe underthrust, and the profile of the helical tooth is in
Equilateral triangle, the detachable head end for holding bar, which is provided with, to be used to connect next detachable threaded connecting sleeve for holding bar, institute
State to offer on the wall of threaded connecting sleeve side and holding rod is plugged with through hole, the through hole, the detachable end thread for holding bar
Check-valves is connected with, is connected between vessel flange, the vessel flange and is provided between the lower end of the check-valves and sampling pipe
For sealed seal washer, the detachable holding bar above check-valves is described to be connected provided with the plate that is connected
Two adjusting screw rods are connected between plate and vessel flange.
It is preferred that, the sampling pipe is lucite sampling pipe, and the sampling head of lucite sampling pipe end is a dozen
Concentric reducer pipe fitting after mill.
It is preferred that, the every detachable length for holding bar is 1 meter.
It is preferred that, the detachable holding bar is the coating steel pipe with anticorrosion effect.
The utility model proposes a kind of bar hold surface sediment sampler, beneficial effect is：The utility model is in behaviour
When making, the bar holds surface sediment sampler, quickly effectively can easily collect the low flow velocity shape such as river, reservoir, lake
Soft under state, sandy and medium-hard surface deposit, can be while effective surface deposit be disposably collected, side
Portable belt, it is simple in construction.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of bar hold the structural representation of surface sediment sampler.
In figure：1. bar is detachably held, 2. threaded connecting sleeves, 3. are connected plate, 4. vessel flanges, 5. check-valves, 6.
Sampling pipe, 7. sampling heads, 8. helical tooths, 9. adjusting screw rods, 10. seal washers, 11. through holes, 12. holding rods.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
A kind of reference picture 1, bar holds surface sediment sampler, including sampling pipe 6 and detachable holding bar 1, sampling pipe 6
Lower end is connected with sampling head 7, and sampling pipe 6 is lucite sampling pipe, and the sampling head 7 of lucite sampling pipe end is a dozen
Concentric reducer pipe fitting after mill, the every detachable length for holding bar 1 is 1 meter, all part lengths of the sampler 1 meter with
Interior, gross weight is 4.5 kilograms, is convenient for carrying, and the outer wall of sampling pipe 6 is provided with the helical tooth 8 for being easy to the underthrust of sampling pipe 6, spiral
The profile of tooth 8 is in equilateral triangle so that when sampler spiral underthrust, the frictional force between helical tooth 8 and soil
Smaller, sampler spiral underthrust is more prone to.
The detachable head end for holding bar 1, which is provided with, to be used to connect next detachable threaded connecting sleeve 2 for holding bar 1, can be easily
Offered on dismounting and installation, the side wall of threaded connecting sleeve 2 in through hole 11, through hole 11 and be plugged with holding rod 12, under sampler spiral
When inserting, holding rod 12 can be more convenient for controlling sampler preferably to work, and the detachable end thread for holding bar 1 is connected with only
Valve 5 is returned, is connected between vessel flange 4, vessel flange 4 and is provided with for sealedly close between the lower end of check-valves 5 and sampling pipe 6
Seal washer 10, the detachable holding bar 1 positioned at the top of check-valves 5 is provided with the plate 3 that is connected, and be connected plate 3 and equipment method
Two adjusting screw rods 9 are connected between orchid 4, the detachable bar 1 that holds is the coating steel pipe with anticorrosion effect, most long to bear
7.
Operation principle：Go deep into after sampler is connected in water, water and surface deposit can enter in sampling pipe, sampling
After end, sampling pipe is proposed from water, check-valves 5 during proposition is because negative pressure is closed, and all water and deposit are also because negative pressure
It will not down reveal, be placed in after sample collection together with sampler in sample collection vessel, the connecting bolt of check-valves 5 is twisted
Pine, discharges pressure, and all surface deposits enter in collection vessel together in company with water, and sample collection is finished.
The utility model is in operation, and the bar holds surface sediment sampler, quickly effectively can easily collect river
Soft, sandy and medium-hard surface deposit under the slow flow states such as stream, reservoir, lake, can disposably collected
While effective surface deposit, it is convenient for carrying, it is simple in construction.
More than, only the utility model preferably embodiment, but protection domain of the present utility model do not limit to
In this, any one skilled in the art is in the technical scope that the utility model is disclosed, according to the utility model
Technical scheme and its utility model design be subject to equivalent substitution or change, should all cover protection domain of the present utility model it
It is interior.
