Embodiment Construction

[0028] The technical solutions of the present invention will be further described in detail below with reference to specific embodiments.

[0029] see Figure 1-3 , the present invention provides a columnar sediment sampling system with an in-situ data acquisition function, including a data collector (a hydrological data collector 1 , a heat flow data collector 2 ) and a columnar sampler 3 . The hydrological data collector 1 includes a connecting rod 11 , a bracket 12 and a multi-parameter hydrological recorder 13 . The multi-parameter hydrological recorder 13 is installed in the bracket 12 , and the hydrological data collector 1 is installed above the cylindrical sampler 3 through the connecting rod 11 . The length of the connecting rod 11 is longer than the long side of the bracket 12 , and the tail is annular.

[0030] The heat flow data collector 2 includes a heat flow meter (not marked in the figure) and a heat flow meter support 21 (such as image 3 shown). The heat f...

Abstract

The invention provides a columnar sediment sampling system with in-situ data acquisition function, including a data collector and a columnar sampler, the data collector includes a hydrological data collector and a heat flow data collector, and the hydrological data collector includes a multi-parameter hydrological Recorder, bracket and connecting rod, the multi-parameter hydrological recorder is installed in the bracket, the hydrological data collector is installed above the cylindrical sampler through the connecting rod, and the cylindrical sampler is equipped with ballast lead block and sampling pipe. The invention can realize the continuous acquisition of the full water depth and multi-parameter hydrological data of the column sampler being lowered once, and make full use of the ship time when the sampler is lowered and recovered.

Description

technical field [0001] The invention belongs to the technical field of marine observation, and particularly relates to a columnar sediment sampling system with an in-situ data acquisition function. Background technique [0002] When conducting marine sediments, sampling operations are often required to obtain marine sediments with a certain thickness and complete sedimentary sequence. The common sampling method is the columnar sediment sampler. The invention can make the sampler penetrate into the seabed sediments in a vertical attitude, ensure high-quality and high-efficiency acquisition of deep-sea seabed columnar sediment samples, and meet the sampling requirements of columnar sediments in deep-water areas. [0003] For example, the following prior patent application, patent number CN108760375A, is named as a gravity columnar sediment sampler, the top side wall of the tubular part is provided with a drainage window, a sample tube and a retaining ring are installed inside,...
