An anti-interference device for seabed sediment sampling

Abstract

An anti-interference device for seabed sediment sampling, comprising a housing, a water storage tank is fixedly installed at both ends of the housing, a buffer ball is fixedly installed at the end of the water storage tank away from the housing, and the upper end of the housing is fixed A hydraulic rod is installed, and fixed rods are fixedly installed on both sides of the upper end of the hydraulic rod, and a connecting rod is fixedly installed on the side of the fixed rod close to the hydraulic rod. A fixed frame is hinged through and extended to the lower part of the isolation plate, and the opposite sides of the two symmetrical fixed frames are fixedly connected with clips through elastic blocks. Through the combined use of clamping strips and clamping blocks, irregular-sized stones can be effectively clamped, avoiding the operation process in which the collected sediments accidentally fall into the water due to the relatively large flow of seawater, resulting in sampling failure, so that it can be used Make sure that the stones will not fall casually, so that it is convenient to bring up the taken things.

Description

Technical field [0001] The present invention relates to the field of marine engineering, in particular a subsea deposit sampling anti-interference device. Background technique [0002] The marine sediment refers to the general term of subsea deposits formed by various marine deposition, usually collecting these marine sediments for detection, observing whether there is natural gas, oil and other substances in this sea area, but the prior art sediment sediment When the sampling device is acquired, it is difficult to ensure that the semicakement is agitated when the seafris is sampled due to the seawater sediment, resulting in water quality, and needs to be sampled. Sediments under section under section were turbid, and washed away by sea water, so that the sample data was not accurate. After the seafris sediments were all deposited, they can sample it. Inventive content [0003] (1) Technical solution [0004] In order to achieve the above-mentioned subsea deposits, the present i...

Problems solved by technology

[0002] Marine sediment refers to the general term for the seabed sediments formed by various marine depositions. These marine sediments are usually collected for detection and analysis to observe whether there are natural gas, oil and other substances distributed in this sea area. However, the prior art seabed sediments When the sampling device is collecting, due to the high fluidity of seawater and the large number of marine organisms on the seabed, it is difficult to ensure that there will be no agitation of seabed organisms when sampling seabed sediments, resulting in water quality changes, and the need for sampling. Part of the sediments under the seabed are all turbid and washed away by seawater, which makes the sample data inaccurate. It is necessary to wait until all the seabed sediments are deposited before sampling
