FIG.1
[0001] The present disclosure belongs to the technical field of marine
observation, and specifically relates to a columnar sediment sampling system with
an in-situ data acquisition function.
[0002] During treatment of marine sediments, a sampling operation is often
required to obtain marine sediments with a certain thickness and complete
deposition sequence. A common sampling method is a columnar sediment sampler.
The present disclosure can make the sampler penetrate into bottom sediments in a
vertical pose to ensure obtaining a high-quality and high-efficiency deep-sea bottom
columnar sediment samples and to meet a sampling need of columnar sediments in a
deep water region.
[0003] For example, in the following prior Chinese Patent Application No.
CN108760375A, entitled "A kind of gravity column shaped deposit sampler" the top
side wall of a tubular part is provided with a drainage window, and a sample pipe
and its snap ring are installed inside. The outer wall of the tubular part is provided
with a stop ring. The upper outer wall of the drainage window is provided with a
bearing seat and a lead block load. An altimeter, a pressure sensor and a releaser are
installed under the bearing seat. Two mutually perpendicular propellers are arranged
in the middle of the sampling pipe. During use, the sampler penetrates into the
bottom sediment in a vertical pose to obtain samples of deep bottom columnar
sediments to meet the sampling need of the columnar sediments in the deep water
region.
[0004] The columnar sampler of the prior application has the following limitations and deficiencies.
[0005] The existing columnar sampler can only obtain samples when it hits
the bottom, and then the sediments are tested and analyzed in a laboratory to acquire
desired data. However, the processes of lowering and withdrawing a sampler in
seawater takes the longest ship time for sampling, but the in-situ data cannot be
obtained. If the sampling station needs hydrological information (such as parameters
of temperature, salinity, chlorophyll, turbidity, and dissolved oxygen) of a sediment
sampling station, a CTD lowered by a midship deck can only be used for data
acquisition, which takes twice the ship time, and it cannot acquire the water from the
bottom close to the sediments on the seabed.
[0006] In addition, in marine geological observation and research, acquisition of in-situ heat flow data of the sediments is of great significance. To
acquire heat flow information of the sediments, the equipment needs to be lowered
for data acquisition. If information such as type and chemical composition of the
sediment at a heat flow collection site needs to be acquired, the sediment sampler
needs to be lowered again, and the seabed sampling positions cannot be completely
consistent.
[0007] The aim of the present invention is to alleviate or provide an
alternative solution to the technical problems discussed above.
[0008] The present invention aims to provide a columnar sediment sampling
system with an in-situ data acquisition function, so as to achieve continuous
acquisition of full -depth-water multi-parameter hydrological data and acquisition of
heat flow data of sediments in a single lowering of a columnar sampler, and fully
utilising the ship time for lowering and withdrawing of the sampler.
[0009] In order to achieve the forgoing aim, the present invention provides
the following technical solution.

a long edge of the bracket 12, and the tail is of a circular ring shape; and the portable head 31 of the columnar sampler 3 is sleeved in the circular ring of the tail of the connecting rod 11.
[00027] The heat flow data acquisition unit 2 includes a heat flow meter (not

cylindrical; the top end is provided with a fixing hole; the lower end is a slope; the
side surface is half hollowed; and the non-hollowed side surface is connected with
the upper bottom of the trapezoid fixing sheet. In the sampling process of the
columnar sampler 3, the heat flow meter bracket 21 can protect the heat flow meter
