Sampling test platform of full ocean depth airtight sampler

Abstract

The invention discloses a sampling test platform of a full ocean depth airtight sampler. The sampling test platform comprises a cylinder, a mud box, a hydraulic cylinder, a sliding assembly, columns and a console. The hydraulic cylinder is vertically mounted in the cylinder. A piston rod of the hydraulic cylinder extends out of the cylinder. The upper end of the piston rod is connected to the sliding assembly. A tension sensor is arranged on the piston rod. The columns are vertically mounted on the top plate of the cylinder. The mud box is arranged outside the cylinder and is close to the cylinder. The sliding assembly comprises a sliding support and a sampler clamping apparatus. The sliding support is provided with guiding holes corresponding to the columns. The guiding holes are set on the columns. A proximity switch, a displacement sensor and the tension sensor are connected to the console. The sampling test platform of the full ocean depth airtight sampler has simple, compact and reasonable structure, and can provide an experimental basis for studying the relationship between sampling efficiency of the full ocean depth sediment sampler and the sampler structure form, sampling speed, diameter of sampling tube and the like, and reduces the design and development cost.

Description

technical field [0001] The invention relates to a sampling test platform for an all-sea deep airtight sampler. Background technique [0002] There are extremely rich mineral resources in the seabed crust, including oil, natural gas, polymetallic nodules, cobalt-rich crusts, hydrothermal sulfides, marine organisms, gas hydrates, and clay minerals, etc. These resources have great economic value and strategic importance. significance. Today, as land resources are depleting day by day, human beings pay more and more attention to the development and utilization of marine resources. [0003] At present, developed countries such as the United States, Japan, Australia, and China have made major breakthroughs in seabed technology, and have successively developed deep-sea airtight sampling devices, providing an important guarantee for the research of seabed surface organisms and other research. However, at this stage, the sampling efficiency of domestic seabed sediment samplers is o...

AI Technical Summary

Problems solved by technology

However, at this stage, the sampling efficiency of domestic seabed sediment samplers is often not high, and there is no in-depth research on the relationship between sampling efficiency and factors such as sampler structure, sampling speed, and sampling tube diameter; moreover, seabed sampling is often several kilometers or even Tens of thousands of meters, the harsh environment is very unfavorable for the test verification of the sampler in the development and design process; even if the seabed sampling test is carried out, the cost of sampling test is often very high
