Problems solved by technology

[0004] Aiming at the technical problem that the existing sampler has single function and is difficult to recycle, the present invention proposes a deep-sea sampler that can take water samples at multiple depths and mud samples at a fixed depth. The sampler can automatically float up and is easy to recycle.

Embodiment

[0022] Example: such as figure 1 , figure 2 As shown, an automatic recovery deep-sea sampler includes a metal shell 1. The shell 1 is thick at the top and thin at the bottom, light at the top and heavy at the bottom. sediment layer. An air bag compartment 2 , a compressed gas compartment 3 and a sampling compartment 4 are sequentially arranged in the casing 1 from top to bottom.

[0023] When recovering the sampler, the airbag chamber 2 is filled with gas to provide buoyancy for the sampler. The upper part of the airbag compartment 2 is provided with a drainage hole 21 communicating with the outside, and the lower part of the airbag compartment 2 is equipped with an airbag 22 made of high elastic rubber. Compressed gas is contained in the compressed gas chamber 3 , and a solenoid valve 31 communicating with the inside of the air bag 22 is installed on the wall of the compressed gas chamber 3 . When the sampler needs to be recovered, the solenoid valve 31 is opened, and th...

Abstract

The invention provides an automatic recovery deep-sea sampler. The automatic recovery deep-sea sampler comprises a housing, wherein a gas bag bin, a compressed gas bin and a sampling bin are sequentially arranged in the housing from top to bottom; a gas bag is mounted at the lower part of the gas bag bin; the compressed gas bin contains a compressed gas; a solenoid valve communicated with the interior of the gas bag is mounted on the wall of the compressed gas bin; and a main control panel and a plurality of water sample bins and mud sample bins are arranged in the sampling bin. The automaticrecovery deep-sea sampler is very suitable for deep-sea bottom sampling detection, and can not only record variations of seabed distance, pressure and temperature but also automatically take water samples and mud samples in different seabed depths. An automatic recovery device is arranged inside. In case of no cable connection, the gas bag bin can be filled with the compressed gas to realize automatic floating of the sampler. The sampler is high in recovery ratio, and realizes efficient sampling of deep-sea water, bottom sediments and the like.

Description

technical field [0001] The invention belongs to the field of seabed sampling devices, in particular to an automatic recovery deep sea sampler. Background technique [0002] The deep sea area is rich in oil, natural gas and other oil and gas resources, and it is the largest potential strategic resource base on the earth that has not been fully understood and utilized by human beings. With the intensification of energy problems, the importance of deep-sea energy development and research has become increasingly prominent. Sampling seabed sediment and seawater is the first step in finding and exploring marine oil and gas resources and microbial resources, and is the basis for engineering geological exploration and environmental ecological research. [0003] For decades, marine sediment sampling techniques have mostly been based on traditional shipborne cable samplers, such as gravity box, grab and piston column samplers. However, these traditional ship-mounted cable samplers n...
