Embodiment Construction

[0032] The following examples can make those skilled in the technical field understand the present invention more comprehensively, but do not limit the present invention in any way.

[0033] The dispensing type autonomous surface sediment sampling device in the present invention includes a hollow shell inside. The whole of the device is capsule-shaped, including a hemispherical tail unit 4; the housing is divided into two cavities by an upper partition 202, thereby forming a hemispherical head unit 1 and a cylindrical middle unit 2; the end of the housing Closed by the bottom partition 213, the tail unit 4 and the bottom partition 213 are detachably fixedly connected; the connection between the upper partition 202 and the middle partition 213 and the shell is provided with a triangular support plate.

[0034]The inner cavity of the middle unit 2 is in a sealed state, and is divided into an upper gas cylinder cavity and a lower electrical cavity by a middle partition 210, where...

Abstract

The invention relates to a sea floor exploration device, and is intended to provide a release type independent surface sediment-sampling device. The device, which is shaped like a capsule as a whole, comprises a semispherical tail unit; a shell is divided by an upper partition into two cavities; the end of the shell is closed by a bottom partition, and the tail unit and the bottom partition are detachably fixedly connected; a middle unit is divided by a middle partition into an upper gas cylinder cavity and a lower electrical cavity, wherein electromagnetic valves, a high-pressure gas cylinder and a low-pressure gas cylinder are arranged in the gas cylinder cavity, and a control and detection unit is arranged in the electrical cavity; at least three alar plates are evenly arranged along an axial direction on the shell of the middle unit; and a sampling tube is mounted on the tail unit. The sea floor exploration device does not require a ship to go to the sea for retrieval, and can be released and retrieved along the way by utilizing a ship. The invention does not require a ship to drift on the sea surface and wait for sampling to finish before retrieval and return, shipping cost and manpower cost are low, and the release type independent surface sediment-sampling device is particularly suitable for cases of sampling surface sediments on sea floors of water areas, such as shallow seas and offshores, on a large scale, and is highly practical.

Description

technical field [0001] The invention belongs to a seabed exploration device, and relates to an underwater surface layer sampling device for autonomous sinking and floating, in particular to a novel underwater sediment sampler containing an electrically controlled floating body. Background technique [0002] Due to the increasingly intensified competition for global marine resources, the composition analysis of seabed sediments has gradually become the top priority of marine strategies of various countries, and the extraction of underwater sediments has naturally become an increasingly critical link. Abroad already has a batch sampling plan such as the "ARGO plan", while my country has just started, and is still in the initial stage of manual throwing and artificial take-up fixed-point sampling. Most of the large-scale seabed sampling in our country is carried out by large ships sailing to the sampling point, throwing the sampler and staying there until the sampling is finish...
