Description

MULTI-PIPE AND BOX-TYPE INTEGRATED SAMPLER APPLICABLE TO
DEEP-SEA SEDIMENT SAMPLING OPERATION
TECHNICAL FIELD
[01] 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.
BACKGROUND ART
[02] 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.
[03] 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. 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). 2. After the box-type sampler is lowered and withdrawn, if the multi-pipe sampler needs to be lowered again, the bottom hit points of the box-type sampler and the multi- pipe sampler cannot be completely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.
3. Multi-pipe sampler equipment at present is relatively complex in structure, includes many parts, and takes a relatively long time for assembling and disassembling. 4. At present, the 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.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[22] The technical solution of the present invention is further described below with reference to specific embodiments.
[23] 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 5 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 2203 stainless steel.
[24] 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.
[25] 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 1s 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.
[26] 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.
[27] 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.
[28] 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.
[29] 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.
[30] 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.
[31] 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.
