Problems solved by technology

[0004] Patent Publication No. CN207570850U has the same technical field as this application, solves the same technical problems, and discloses the most technical features, which can be used as the closest prior art of this application, but its function is single, only has the function of water intake, and can no longer carry out soil extraction. At the same time, the airtightness of the equipment is not taken into consideration. In addition, the sediment collection structure disclosed in CN105547752B can only take one sampling point at a time, so it needs to be recycled continuously, take samples, and then lower down to take samples. The process is very cumbersome

Embodiment 1

[0035] As shown in the figure, the offshore marine water quality and sediment sampling structure includes an outer sleeve 34, which is formed by interlocking two semi-cylinders, and the bottom of the outer sleeve 34 is connected with a base 36 through an adjustment rod 3, An organ cover 2 is connected between the outer sleeve 34 and the base 36 . Rollers 1 are installed on the base 36, and the base 36 is used to support the landing of the device on the seabed sediment layer. At the same time, the base 36 is also provided with a searchlight and a camera, which can monitor the working process when the device is working.

[0036] The top of the outer sleeve 34 is connected with an upper sleeve 37, and the upper sleeve 37 is connected with a steel wire rope 6, and the spacer discs 5 are evenly distributed on the steel wire 6; the edge of the outer sleeve 34 is evenly installed There are water intake structures 700, and there are multiple water intake structures 700 arranged in a c...

Embodiment 2

[0052] This embodiment provides another water intake method, and other structures and principles are the same as those in Embodiment 1.

[0053] As shown in the figure, the offshore marine water quality and sediment sampling structure includes an outer sleeve 34, which is formed by interlocking two semi-cylinders, and the bottom of the outer sleeve 34 is connected with a base 36 through an adjustment rod 3, An organ cover 2 is connected between the outer sleeve 34 and the base 36 . Rollers 1 are installed on the base 36, and the base 36 is used to support the landing of the device on the seabed sediment layer. At the same time, the base 36 is also provided with a searchlight and a camera, which can monitor the working process when the device is working.

Abstract

The invention discloses a sampling structure of nearshore marine water quality and sediment. The sampling structure comprises an outer cylinder sleeve, the outer cylinder sleeve is formed by two semicircular cylinders in a mutually locked mode, a base is connected to the bottom of the outer cylinder sleeve through an adjusting rod, and rollers are mounted on the base. The sampling structure is characterized in that an upper cylinder sleeve is connected to the upper part of the outer cylinder sleeve, the upper cylinder sleeve is connected with a steel wire rope, and interval plates are mountedon the steel wire rope in an evenly-distributed mode; and water intake structures are mounted on the cylinder edge of the outer cylinder sleeve in an evenly-distributed mode, the water intake structure comprises a water intake groove, and a water intake tank is mounted in the water intake groove. The sampling structure has the beneficial effects that by utilizing reasonable structure design, watersamples of different depths can be collected, meanwhile sediment soil samples at different positions can be taken without recovering the sampling structure, and the soil samples can be recovered in advance, less time is taken in the whole process, usage is convenient, the sampling speed is high, and the sampling structure is suitable for being used and popularized.

Description

technical field [0001] The invention relates to a marine water quality and sediment sampling structure and a sampling method thereof, belonging to the technical field of marine survey engineering. Background technique [0002] Seabed sampling is the work of collecting seabed sediment and rock samples with sampling instruments. It is a means of marine research. The tools used for sampling include trawls, grabs, cylindrical samplers and shallow seabed drills. After sampling, conduct preliminary observation and description on the material composition, structure, structure and color of the sample in time on board, conduct simple tests on humidity, plasticity, compressive strength, etc., and extract pore water; and retain part of the sample number and seal it up. According to the preliminary observation on board, a sketch of the ocean bottom can also be drawn for indoor research reference. [0003] As a publication number is CN207570850U discloses a marine sampling device, whic...
