Embodiment
The embodiment to the present invention is described in further detail with reference to the accompanying drawings and examples.Following examples
For illustrating the present invention, but it is not limited to the scope of the present invention.
As shown in figure 1, a kind of deep-water sludge sampler for providing of the present invention, including probe tube 1, piston 2, pull bar 3,
Hand 4, closing cock 5, bottom cover 6, top closure 7 and capping pull bar 8, piston 2 are fitted tightly in probe tube 1, and piston 2 is with pushing away
Pull bar 3 is connected, and handle 4 is arranged on the top of pull bar 3, and top closure 7 and bottom cover 6 are respectively provided at the top of probe tube 1
And bottom, top closure 7 and bottom cover 6 connect in the outside of probe tube 1 by covering pull bar 8, and closing cock 5 is located at bottom envelope
One end of lid 6, and closing cock 5 coordinates with bottom cover 6, by covering the connection function of pull bar 8, probe tube 1 is connected two
Capping forms overall, and the inwall of probe tube 1 is brought into close contact piston 2, and piston 2 is pulled in probe tube 1 by the effect of pull bar 3
Wall is moved, using the inner carrier both sides pressure difference of probe tube 1, so as to draw bottom silt.
The sludge sampler of the present invention, the material of its probe tube 1 is fiberglass, and the wall thickness of probe tube 1 is 5mm, and internal diameter is
50mm, external diameter is 60mm, a length of 500mm, is verified through case history, and such dimensions has practice operation value, for
Deep water takes mud better, and sufficient mud can be taken to be analyzed.
As shown in figure 1, the inwall of piston 2 and probe tube 1 is brought into close contact, 1 point by probe tube of piston 2 is two chambers, and should
The material of piston 2 is rubber, when carrying out mud sampling operation, only pull bar 3 need to be pulled, due to the probe tube 1 of the both sides of piston 2
Pressure change in cavity so that mud sucks the intracavitary of probe tube 1, smoothly obtains mud sample in deep water.
As shown in figure 1, the material of pull bar 3 and handle 4 is stainless steel, one end that pull bar 3 is connected with piston 2 is provided with
In screw thread, other end connection handle 4, handle 4 and the formation T-type structure of pull bar 3, the present embodiment, pull bar 3 is passed through in piston 2
Between through hole after nut check is installed in the end of pull bar 3, pull bar 3 is fastenedly connected with piston 2, while having enough resist
Tensile strength, the stressing conditions when pulled of piston 2 when meeting sampling, it is necessary in explanation, the present embodiment, pull bar 3 it is straight
Footpath is slightly less than the through-hole diameter of piston 2, and pull bar 3 can be made to pass through piston 2.In specific implementation, it can open non-through in the middle of piston 2
Screw thread is opened inside hole, the non through hole of piston 2 to be connected through a screw thread with the end of pull bar 3, forms firm annexation, and, push away
It can also be integrated member that pull bar 3 assembled can be connected with handle 4.
As shown in figure 1, capping pull bar 8 is two pieces, respectively symmetrically the both sides outside the wall of probe tube 1, make capping connection pass
It is more stable, reaches more preferable plugging effect, and the symmetrical mode set in both sides makes stress evenly.
As shown in figure 1, top closure 7 and the edge of bottom cover 6 are accordingly provided with first through hole, capping pull bar 8 is passed through
Corresponding first through hole on top closure 7 and bottom cover 6, covers the two ends attaching nut of pull bar 8, wherein close to bottom cover
The nut of 6 one end will cover pull bar 8 and the relative position of bottom cover 6 is fixed, and the nut close to the one end of top closure 7 is used
Wing nut, can adjust fixed relative position, to reach more preferable plugging effect.When sampler takes mud, it will need to cover
The nut at the two ends of pull bar 8 is tightened, and fixed good position is sampled again.
As shown in figure 1, the center of top closure 7 is provided with the second through hole, pull bar 3 passes through the second through hole, stretches to probe tube 1
Outside chamber, handle 4 is connected, is easy to preferably operate pull bar 3, carry out the sampling of mud, the center of bottom cover 6 is provided with threeway
Hole, third through-hole is fitted close with closing cock 5, the sampling end of probe tube 1 is formed good plugging effect, during concrete operations,
When needing to carry out deep-water sludge sampling, closing cock 5 is pulled away into bottom cover 6, handle 4 is pulled out and is sampled, sampled
Cheng Hou, installs closing cock 5, the mud sample of sampling is enclosed in probe tube 1, and band backwater surface is analyzed.
In the present invention, the material of bottom cover 6 and top closure 7 is hard rubber, the two ends for closing probe tube,
Using hard rubber, hardness and intensity are big, and corrosion-resistant, cost is low.
The material of closing cock 5 is is connected with cotton rope between poly- polypropylene fibre, and closing cock 5 and probe tube 1, when it is implemented, can be
Wire rope handling is punched on closing cock 5 to lie on probe tube, is dropped to prevent opening during closing cock 5.
It should be noted that third through-hole is opened in bottom cover 6 for thief hole, for the ease of the smooth sampling of mud,
On the premise of requirement is met, the diameter of the third through-hole need to be as big as possible, and the diameter tends to be suitable with sampling bore
When, mud sampling is more convenient, sampling efficiency is higher.
In summary, a kind of deep-water sludge sampler that the present invention is provided, principle is reliable, simple in construction, is convenient for carrying, just
In dismounting and regulation, while selection rationally, can resist indeformable impaired under the effect of deepwater regions hydraulic pressure, solve not special
The problem of deep-water sludge sampler, it is ensured that underwater construction is smoothed out.
It the above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Say, without departing from the technical principles of the invention, some improvement and modification can also be made, these improvement and modification also should
It is considered as protection scope of the present invention.
