随着ROV（Remotely Operated Vehicles）在大洋科考活动中应用越来越成熟，为了运用ROV取得更丰富的样品，需要针对ROV的特点研发专用的取样工具。考虑ROV搭载的可行性和深海沉积物样本的采集及保存需要保持取样原点压力的需求，设计一套ROV可以搭载使用的深海半自动沉积物保压取样器，研究其深海半自动密封、体积置换及压力损失补偿技术3项基本技术，并对以上技术进行计算分析和实验验证，结果表明该技术方案具有较好的原位保压能力。
As ROVs (Remote Operated Vehicles) used in ocean research activities are more and more mature, sampling tools specially designed for ROV application are needed to obtain rich varieties of deep-ocean samples. Considering the ROV's feasibility and the requirement of pressure retention for deep-ocean sediment sample collection and preservation, a deep-ocean semi-automatic sediment pressure sampleris developed. This paper focuses on three basic technologies of the sampler: deep-ocean semi-automatic sealing, volume displacement and pressure loss compensation. Computational analysis and experiment results indicate the effectiveness of the ROV sampler design.
