Reliable sampling technology for deep-sea sediments is a prerequisite for studying the sedimentary environment in the geological history, the mechanical characteristics of sediments and sediment biology. In this study, we develop a new sampling device in order to achieve a convenient and economic pressure sampling for hadal sediments. The overall structure, as well as the key component such as the pressure-holding part, and the sealing structure are designed. The feasibility of the device was verified through field tests. Furthermore, the sampling process is analyzed by the computer simulation. It is found that the sampling length is determined by the open diameter and the installation position of the core keepers. According to the simulation, the structure is optimized, which is beneficial to the further improvement of the sampling length.

Hadal级登陆器携带的新型泥沙压力采样装置

可靠的深海沉积物采样技术是研究地质历史中沉积环境,沉积物力学特性和沉积物生物学的先决条件。在这项研究中,我们开发了一种新的采样装置,以实现方便而经济的哈德沉积物压力采样。设计了整体结构以及关键部件(如压力保持部分)和密封结构。该设备的可行性通过现场测试得到了验证。此外,通过计算机仿真分析了采样过程。可以发现,采样长度是由铁芯保持架的开口直径和安装位置决定的。通过仿真,对结构进行了优化,有利于进一步提高采样长度。
