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...
