FIG.1
[0001] The present disclosure belongs to the technical field of marine
observation, and specifically relates to a multi-pipe and box-type integrated sampler
applicable to deep-sea sediment sampling operation.
[0002] Common samplers include box-type samplers and multi-pipe
samplers for sampling of marine surface sediments. The box-type sampler can
obtain a surface sediment with a certain thickness, and the multi-pipe sampler can
obtain a surface sediment with a complete deposition sequence and get its overlying
water. The two samplers focus on different aspects, and are both important sampling
methods in the field of marine observation and research.
[0003] The currently used sampling methods have the following defects and
limitations.
1. The box-type sampler can only be mounted on an observation platform for
box-type sampling. If multi-pipe sampling is required, the box-type sampler
needs to be replaced with the multi-pipe sampler for re-sampling.
2. The ship time for box-type sampling and multi-pipe sampling is about twice
of that of single sampling. This is extremely disadvantageous for sampling
work in scientific expedition trips with lengthy ship time and extreme
environments (such as a polar multi-sea-ice environment).
3. After the box-type sampler is lowered and withdrawn, if the multi-pipe
sampler needs to be lowered again, the bottom hit points of the box-type
sampler and the multi-pipe sampler cannot be completely superposed, and
in-situ sampling cannot be achieved. Samples collected by the two samplers are often used for comparative studies. Although the latitudes and longitudes are very close, the chemical properties and material compositions of samples may be quite different due to the complex and changeable submarine topography.
4. Existing multi-pipe sampler equipment is relatively complex in structure,
includes many parts, and takes a relatively long time for assembling and
disassembling.
5. However, the existing box-type or multi-pipe sampler can only obtain
samples when it hits the bottom of the seabed, and then the sediment is analyzed
in a laboratory to obtain required data. However, the processes of lowering and
withdrawing a sampler in seawater takes the longest ship time for sampling, but
any in-situ data cannot be acquired. If the sampling station needs hydrological
information of a sediment sampling station, a CTD lowered by a midship deck
can only be used for data acquisition, but it cannot cover the body of water at
the bottom, close to bottom sediments.
[0004] The present invention aims to provide a multi-pipe and box-type
integrated sampler applicable to deep-sea sediment sampling operations to achieve
an in-situ sampling and single lowering of a multi-pipe sampler and a box-type
sampler, and to obtain an in-situ acquisition of multi-parameter hydrological data
and sectional measurement of water data, and to fully utilise the ship time of
lowering and withdrawing the samplers.
[0005] In order to achieve the forgoing aims, the present invention provides
the following technical solution.
[0006] The present invention provides a multi-pipe and box-type integrated
sampler applicable to deep-sea sediment sampling operations, including a scraper
knife connecting rod system, a box-type sampling system, a multi-pipe sampling
system, and an in-situ hydrologic parameter collection system.
[0007] Preferably, the present invention further provides a scraper knife
connecting rod system which includes a lifting fence used to be upwards connected
to a driving mechanism and a release lock catch fixed on a bracket, and which is
connected with a scraper knife at the bottom end of the sampler through a
connecting rod.
[0008] Preferably, the present invention further provides a box-type
sampling system with a ballast lead block; wherein the top is provided with a sealed
box cover; the bottom is provided with a sampling box body; a fixed plate is
arranged on the outer side; the multi-pipe sampling system is connected to the fixed
plate through a small fixed plate; and the in-situ hydrological parameter collection
system is mounted above the ballast lead block.
[0009] Preferably, the present invention further provides a sampling pipe
that is a PC pipe, and an upper cover and a lower cover wherein each are provided
with a spring structure.
[00010] Preferably, the present invention further provides two sets of
multi-pipe sampling systems which are mounted on two sides of the box-type
sampling system.
[00011] Preferably, the present invention further provides that a main body of
the multi-pipe sampling system is the sampling pipe; wherein the top of the
sampling pipe is provided with the upper cover; and the bottom is provided with the
lower cover.
[00012] Preferably, the present invention further provides that the bottom of
the multi-pipe sampling system is slightly higher than the bottom of the sampling
box body.
[00013] Preferably, the present invention further provides an in-situ
hydrological parameter collection system, wherein the in-situ hydrological
parameter collection system is composed of a fixed bracket and a multi-parameter
hydrodynamic recorder and provided with an RBR maestro multi-channel water parameter recorder and other equipment.
[00014] Preferably, the present invention further provides that the box cover
is a symmetric openable box cover; a sealant plate is arranged on the inner side; two
sides of the lower part of the sampling box body are arc-shaped and match with the
arc surfaces of the scraper knives.
[00015] Preferably, the present invention further provides that two sides of
the multi-pipe and box-type integrated sampler may be additionally provided with a
control cabin, a camera, a LED lamp, height meter, and other equipment through a
coaxial cable/photoelectric cable to prepare a visualized box-type sampler.
[00016] Preferably, the present invention further provides that a main body
material of the multi-pipe and box-type integrated sampler is high-quality 316L
stainless steel and 2205 stainless steel.
[00017] Preferably, the present invention further provides that the spring
structure is made of tin-phosphor bronze.
[00018] Compared with the existing art, the multi-pipe and box-type
integrated sampler provided by the present invention has the advantages and
beneficial effects listed below:
1. Multi-pipe and box-type jointed sampling can be performed in a single
lowering in a deep-sea environment, so that the sampling efficiency is improved,
and the ship time is more economical.
2. The time for installing and removing the multi-pipe sampler can be shortened,
and the sampling efficiency can be improved.
3. The ship time for lowering and withdrawing the samplers can be fully utilised;
full -depth-water multi-parameter hydrological data is acquired in situ; and sectional
measurement of hydrological data is realized.
4. In-situ sampling of the multi-pipe and box-type samplers at the same station
can be obtained, and the working efficiency is improved.

integrated sampler in a closed state; and
[00020] FIG. 2 is a schematic structural front-view diagram of a multi-pipe

[00022] The technical solution of the present invention is further described
below with reference to specific embodiments.
[00023] Referring to FIGS. 1 and 2, the present invention provides a
multi-pipe and box-type integrated sampler applicable to deep-sea sediment
sampling operations. The sampler penetrates into marine bottom sediments due to
the weight of the equipment. In one lowering, a bottom surface sample can be
extracted, and an in-situ surface sample and an overlying water sample can be
obtained. The sampler specifically includes a scraper knife connecting rod system 1,
a box-type sampling system 2, a multi-pipe sampling system 3, and an in-situ
hydrological parameter collection system 4. A main body material may be made of
high-quality 316L stainless steel and 2205 stainless steel.
[00024] The scraper knife connecting rod system 1 includes a lifting fence 11
used to be upwards connected to a driving mechanism and a release lock catch 13
fixed on a bracket 12, and is connected with two scraper knives 15 at the bottom end of the sampler through connecting rods 14. The release lock catch 13 locks the lifting fence 11 and a sampling box body 25 in water to keep the scraper knives 15 open. After the sampler hits the bottom and is lifted, the release lock catch 13 falls off, and the scraper knives 15 are closed, thus completing the sampling.
[00025] The box-type sampling system 2 is provided with a ballast lead block
23; the top is provided with a sealed box cover 21; the bottom is provided with the
sampling box body 25; a fixed plate 22 is arranged on the outer side; and the
multi-pipe sampling system 3 is connected to the fixed plate 22 through a small
fixed plate 24. The two sides of the lower part of the sampling box body 25 are
arc-shaped and match to the curved surfaces of the sampling scraper knives 15, so as
to achieve a relatively good closing effect. The sealing box cover 21 at the top of the
box body is a symmetrical openable box cover, and the inner side is equipped with a
sealant plate. It is opened symmetrically during lowering and is closed and sealed
during lifting, which can prevent the sample from being wiped out by the water flow
during the lifting process.
[00026] Two sets of multi-pipe sampling systems 3 are mounted on two sides
of the box-type sampling system 2, and the bottom of the multi-pipe sampling
system 3 is slightly higher than the bottom of the sampling box body 25, which is
beneficial to the stability of the equipment. A main body of the multi-pipe sampling
system 3 is a sampling pipe 32; the sampling pipe 32 is a PC pipe; the top is
provided with an upper cover 31, and the bottom is provided with a lower cover 33.
The upper cover 31 and the lower cover 33 are each provided with one spring
structure 34. The spring structure 34 is made from tin-phosphor bronze material.
[00027] The in-situ hydrological parameter collection system 4 is located
above the ballast lead block 23, is composed of a fixed bracket 41 and a
multi-parameter hydrological recorder 42, and can be equipped with an RBR
maestro multi-channel water parameter recorder or other equipment.
[00028] On the basis of a traditional box-type sampler, the present disclosure is additionally provided with a spring device, so that the success rate of sampling is greatly increased. Meanwhile, a balance device is added, so that a phenomenon of a roof failure in sampling caused by a soft bottom can be effectively avoided. The multi-pipe sampler is uniformly distributed around the box-type sampler. This layout can provide that samples can still be obtained in case of tilting, particularly in-situ samples of multiple pipes.
[00029] The multi-pipe sampling system 3 is provided with upper and lower
sealing systems. When the equipment is put into use and penetrates into sediments,
the upper and lower covers of the multi-pipe sampling system 3 and the box cover
21 of the box-type sampling system 2 must be open at all times. After the sampling
is completed, a trap is triggered to close the box cover 21 of the box-type sampling
system 2 and the upper cover 31 and the lower cover 33 of the multi-pipe sampling
system 3, so that the sample is in a sealed state. The equipment is lifted to a deck to
obtain the in-situ sampling.
[00030] In addition, two sides of the multi-pipe and box-type integrated
sampler may be additionally provided with a control cabin, a camera, a LED lamp,
height meter, and other equipment through a coaxial cable/photoelectric cable to
prepare a visualized box-type sampler. This sampler is upgraded to a high-precision
product with a visual function and a real-time information transmission function.
[00031] Although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art still can modify the technical solutions disclosed in the foregoing various embodiments, or make equivalent replacement to partial technical features. Any modifications, equivalent replacements, improvements and the like that are made without departing from the spirit and principle of the present disclosure shall all fall within the protection scope of the present disclosure.
[00032] Any discussion of documents, devices, acts or knowledge in this specification is included to explain the context of the invention. It should not be taken as an admission that any of the material forms a part of the prior art base or the common general knowledge in the relevant art in Australia on or before the priority date of the disclosure herein.
[00033] Where the terms "comprise", "comprises", "comprised" or "comprising" are used in this specification, they are to be interpreted as specifying the presence of the stated features, integers, steps or components referred to, but not to preclude the presence or addition of one or more other features, integers, steps, components to be grouped therewith.
