Description

Technical Field

[0001] The invention belongs to the technical field of marine geological sampling, and in particular relates to a marine geological sediment sampling device. Background Art

[0002] Marine geological sediments refer to materials accumulated through various natural processes in the marine environment. These sediments cover about 70% of the seafloor on the earth's surface. Their formation involves a variety of physical, chemical and biological sedimentary processes. The specific types and distribution are affected by many factors, including topography, water flow dynamics, biological activities, and the source of materials input into the ocean. Sampling and testing marine geological sediments has many scientific significances and practical application values. This will use a box sampler, which is a sediment sampling device with a square or rectangular sampling tube or sampling cylinder. It consists of a tube rack, a sampling box, a heavy hammer, a closed shovel, etc. When the sampler reaches the seabed, the sampling cylinder is inserted into the seabed sediment by the gravity of the heavy hammer, and the closed shovel rotates to cut the bottom sediment into the sampling cylinder. Due to the large cross-section of the sampling cylinder (15 cm × 15 cm, 20 cm × 30 cm, 30 cm × 30 cm), the sediment is less disturbed or basically not disturbed during sampling, which is suitable for taking undisturbed samples.

[0003] Although the existing sampling device can sample marine geological sediments, it can only sample once at a time. After sampling is completed, the sample needs to be taken out before it can enter the ocean again to continue sampling. This makes the work of multiple samplings cumbersome and time-consuming.
