Sampling device

Abstract

The invention discloses a sampling device, and relates to the field of oceanographic survey. The sampling device comprises a sampling component and a balance frame. The sampling component comprises a sampling box, the bottom of the sampling box is provided with an opening, the balance frame comprises a connecting component connected with the sampling component, and at least three support legs distributed around the sampling component. One end of each support leg is connected with the connecting component, and the other end extends below the bottom end of the sampling component. The sampling device can conveniently collect samples, and is applicable to seabed of various complicated terrains. In addition, non-turbulent sampling can be realized, collected samples of sea bottom sediments are high in quality, sampling process can be monitored in real time, and sampling effectiveness is ensured.

Description

technical field [0001] The invention relates to the field of marine survey, in particular to a sampling device. Background technique [0002] Undisturbed sampling of seafloor sediments is an essential item when conducting marine surveys. At present, the box sampler used for sediment sampling operations mainly uses gravity to drive the spatula to seal the back of the box sampler. This back sealing process is relatively large, which disturbs the samples collected by the box sampler, making it impossible to obtain seabed sediments. The original sample of the object. [0003] Moreover, when the existing sampling device sinks into the seabed, the operator cannot know the operating status of the sampling device and the environmental conditions in real time, cannot obtain the sampling depth data in real time, and cannot observe the target area in real time before sampling. As a result, the success rate of sampling and the validity of the sample cannot be guaranteed. [0004] Fur...

At present, the box sampler used for sediment sampling operations mainly uses gravity to drive the spatula to seal the back of the box sampler. This back sealing process is relatively large, which disturbs the samples collected by the box sampler, making it impossible to obtain seabed sediments. undisturbed sample

[0003] Moreover, when the existing sampling device sinks into the seabed, the operator cannot know the operating status of the sampling device and the environmental conditions in real time, cannot obtain the sampling depth data in real time, and cannot observe the target area in real time before sampling. As a result, the success rate of sampling and the validity of the sample cannot be guaranteed

[0004] Furthermore, due to the various topography of the seabed surface, when sampling the seabed sediments, it is often encountered that the seabed surface is uneven. At the same time, the sampling device directly hits the uneven seabed surface, which will also damage the sampling device, which will increase the maintenance cost of the sampling device and shorten the service life of the sampling device
