Problems solved by technology

[0002] Vibration samplers are mainly used to solve the problem of sampling hard sediment areas, such as hard soil layers, sandy sediments, etc. However, when sampling marine sediments, it is necessary to ensure that the sampled sediments are not disturbed. When collecting sediments, For hard sediments, the sampling depth is small, and the traditional vibrating sampler destroys the sediment sequence, and the continuity is poor, resulting in interference during sampling, which cannot guarantee effective sampling

Abstract

The invention belongs to the technical field of sediment sampling equipment and relates to an undisturbed high-frequency vibration sediment sampler. The sampler comprises an outer bin; an inner bin is arranged on the upper portion of the interior of the outer bin; an eccentric motor is installed in the inner bin; the output end of the bottom of the eccentric motor is connected with an inner pipe; an outer pipe is arranged on the outer side of the inner pipe; a sampling mechanism is installed at the bottom end of the inner pipe; side holes are formed in the outer walls of the two sides of the outer bin; fixing rods are detachably connected to the outer walls of the two sides of the inner bin; a base is installed at the bottom of the outer bin; each fixing rod is of an L-shaped structure; The outer bin of the undisturbed high-frequency vibration sediment sampler can perform high-frequency vibration, so that a continuous sediment sample is obtained; undisturbed collection of seabed sediments is ensured; the internal sampling mechanism extends into the sample to perform sampling, so that the sampling depth can be increased, the structure of the sediment sample is prevented from being damaged, and the sediment sampling quality is improved.

Description

technical field [0001] The invention relates to the technical field of sediment sampling equipment, in particular to an undisturbed high-frequency vibration sediment sampler. Background technique [0002] Vibration samplers are mainly used to solve the problem of sampling hard sediment areas, such as hard soil layers, sandy sediments, etc. However, when sampling marine sediments, it is necessary to ensure that the sampled sediments are not disturbed. When collecting sediments, For hard sediments, the sampling depth is small, and the traditional vibrating sampler destroys the sediment sequence and has poor continuity, which leads to interference during sampling and cannot guarantee effective sampling. Contents of the invention [0003] The purpose of the present invention is to provide a non-disturbance high-frequency vibration sediment sampler to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the pres...
