Technical field
The technical field that the invention belongs to deep-water sludge research, relates in particular to the low disturbance sampler of a kind of gravity force type deep water mud.
Background technology
At present, obtain seabed, mud sampling at the bottom of lakebed and reservoir, prospecting means essential in dredging work and the research field of back-silting always, especially the sampling process of deep-water sludge, it is the pith in this prospecting field always, at present, obtain lake, the sampler of the waters shallow-layer mud such as reservoir mainly contains grab bucket, box, the sampling instruments such as gravity type, gravity type silt sampler is because simple in structure, easy to operate and sampling low cost and other advantages, that more normal adopted mud is taked instrument at present, conventional gravity type silt sampler is weight and the sludge sampler deadweight that utilizes weight, in freely falling body mode, pour mud, obtain mud sample.
Current sludge sampler is more for shallow water, apply wider, but the mud sampling equipment for deep water is actually rare, and conventional gravity type silt sampler generally can not guarantee that sealing mechanism triggers safely, be difficult to guarantee sampling success ratio, simultaneously, because hull is unstable and the reason such as undercurrent under water, being difficult to guarantee verticality when sludge sampler enters water, easily there is disturbance in the sample of getting, and the most of structure of existing mud device more complicated all.
Summary of the invention
The object of the present invention is to provide the low disturbance sampler of a kind of gravity force type deep water mud, be intended to solve the complex structure that existing sludge sampler exists, easily there is the problem of disturbance in the sample of getting.
The present invention realizes like this, the low disturbance sampler of gravity force type deep water mud, the low disturbing gravity formula of described deep-water sludge sampler comprises: suspension ring, finer wire, sampling steel pipe, sampling bushing pipe, coupling sleeve, cavity, reinforcing bar, oblique angle steel pipe, keep out sleeve, sealing steel blade, blade spring, dwang, dwang spring, band, flexible pipe, gravity type framework, gravity block;
Described gravity block is arranged on gravity type base of frame, described suspension ring are connected to sampling steel pipe and are fixed to together gravity type framework centre position, a plurality of sampling bushing pipes of described sampling steel pipe device, described coupling sleeve is sealed by band, described sampling steel pipe bottom connects cavity, in described cavity, arrange sampling bottom closing device, described oblique angle steel pipe is continuously fixing by reinforcing bar with sampling steel pipe, described sealing steel blade is by keeping out sleeve jacking, the described sleeve of keeping out is stablized by dwang, described dwang is stablized by dwang spring tension, described finer wire is through flexible pipe connection of rotating bar, described dwang discharges keeps out sleeve, described blade spring causes the incision of sealing steel blade and samples steel pipe sealing.
The low disturbing gravity formula of deep-water sludge of the present invention sampler, simple in structure, impact steadily, sampling success ratio is high, be aided with underwater photographic system and slowly put into mud, low disturbance triggers sampling bottom closing device, has solved poor, the easy disturbance of sealing that traditional gravity type sampler exists, complex structure and the low problem of sampling success ratio.
