Embodiment 1

[0027] Embodiment 1: as figure 1 A portable deep underwater geological columnar sediment collection device in the coastal zone is shown, including a collection unit 1 for collecting deep underwater geological columnar sediments in the coastal zone, and an auxiliary device for performing auxiliary operations on the collection unit 1 unit; the auxiliary unit includes a support unit 2 for fixing the acquisition unit 1, and an operation unit 3 connected to the acquisition unit 1 and the support unit 2 respectively; the acquisition unit 1 includes an acquisition module 11 for acquisition, and for A power module 12 powered by the acquisition module 11;

[0028] The acquisition module 11 includes a lead screw 111, and a sampling assembly 112 that can be installed at the lower end of the lead screw 111;

[0029] Such as figure 1 , 2 As shown, the sampling assembly 112 includes a sampling barrel 1121 with a sampling groove on the side, a sampling cutter head 1122 installed at the lo...

Embodiment 2

[0037] Embodiment 2: Different from Embodiment 1: as Figure 4 As shown, the support rod of the bottom ring is a hollow structure; the upper surface of the support rod of the bottom ring is provided with a feeding hole 211, and a sealing cover can be set on the feeding hole; the center of the lower surface of the support rod of the bottom ring is provided with a discharge hole 212, and the outlet A door sealing assembly 213 is provided at the material hole 212; the door sealing assembly 213 includes a door sealing body with one end movably arranged on one side of the discharge hole 212, and an electric lock installed on the other side of the discharge hole 212 to control the closing of the other end of the door sealing body.

Embodiment 3

[0038] Embodiment 3: The difference from Embodiment 1 is that: the support unit 2 includes a support bottom ring 21 whose cross section is a regular quadrilateral; there are four support rods 22 .

Abstract

The invention provides a portable coastal zone underwater deep geological columnar sediment collecting device, which comprises a collecting unit and an auxiliary unit, wherein the collecting unit is used for collecting coastal zone underwater deep geological columnar sediments; the auxiliary unit is used for conducting auxiliary operation on the collecting unit; and the auxiliary unit comprises asupporting unit used for fixing the collecting unit, and an operation unit connected with the collecting unit and the supporting unit. The portable coastal zone underwater deep geological columnar sediment collecting device is reasonable in overall structural design, the collecting unit and the supporting unit which operate underwater achieve a detachable structure through a mounting block and a mounting hole, and the device has high convenience in use and is more convenient to transport.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a portable coastal zone underwater deep geological columnar sediment collection device. Background technique [0002] Oceans have existed on Earth for 4 billion years. During this long geological age, the substances that were imported into the ocean by land, rivers and the atmosphere include soft sediment, dust, remains of animals and plants, cosmic dust, etc., as well as things that fell into the seabed during human activities. There are too many to count. Scientifically, these things are collectively referred to as seabed sediments. [0003] The release of endogenous pollutants in sediments is one of the main sources of water quality deterioration, and its research can provide a favorable basis for the restoration of water quality. The study of sediments must be collected. In the prior art, grab samplers and columnar gravity samplers are mainly used to collect sedim...
