Embodiment Construction

[0029] Such as Figure 1-5 A deep-sea shallow sandy sediment sampler is characterized in that it includes a vibrating part I and a sampling part II located below the vibrating part I, and the vibrating part I includes a sealed cabin 3, a counterweight 2 above the sealed cabin 3 and The lifting ring 1 on the top of the counterweight 2, the sealed cabin 3 is provided with an acceleration sensor 4, a controller 5, a battery 6 and a driving motor 7;

[0030] The sampling part II includes a box with an open bottom, the side of the box is a side plate 11, and the top is a top plate 14. The top plate 14 and the side plate 11 are connected to each other by a fixing bolt 13, and the side plate 11 is provided with a plurality of Pressure relief hole 10; ensure that the pressure inside and outside the box is always consistent;

[0031] A plurality of vertical plates 15 parallel to the left and right side plates 11 are arranged inside the box body, and the upper edge of the vertical plat...

Abstract

The invention discloses a deep sea shallow arenaceous sediment sampler and a sampling method thereof. The deep sea shallow arenaceous sediment sampler comprise a vibrating part and a sampling part which are connected with each other through a bolt, and can be separated from each other freely; the vibrating part comprises a hoisting ring, a counterweight and a sealed cabin; a battery, an acceleration sensor, a driving motor and a controller are arranged in the sealed cabin; a top cover of the sampling part is detachable; side walls and the top cover are embedded together; and rigid sheets whichare freely detachable are distributed on the side walls. The rigid sheets can be bent freely when the sampling part is inserted into the seabed, so that the insertion is hardly influenced. During removal of the sampler, the rigid sheets prevent internal arenaceous sediment from sliding downwards. A plurality of pressure relief vents are distributed in the top cover and the side walls of the sampling part in order to ensure constant pressure inside and outside a sampling box. The deep sea shallow arenaceous sediment sampler is simple in structure, and convenient to operate. The number of sidewalls can be increased and reduced as required, and the bottom of a sampling device can be sealed hermetically during removal from the sediment, so that the runoff of loose sediment samples is effectively prevented; the internal and external pressure difference is consistent; the sampling difficulty is lowered; and the sampling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of deep-sea sediment sampling, and in particular relates to a deep-sea shallow sandy sediment sampler and a sampling method thereof. Background technique [0002] A large number of seabed sediments are distributed on the seabed. From the continental shelf to the deep-sea basin, the particles of the seabed sediments vary greatly, mainly including coarse sand, fine sand, silt, silty clay and deep-sea clay and other types of sediments. Seabeds are developed in some areas Sand wave, especially in the northern shelf and shelf break area of ​​the South China Sea. Seabed sampling is the use of samplers to obtain seabed sediment or rock samples. It is an important means of marine research. At present, the commonly used seabed sediment samplers include grab type, gravity type, piston type, hammer type and vibration type, etc. , and the vibrating sampler has the highest sampling efficiency. Conventional samplers can...
