A storage container with variable inner diameter to achieve triaxial compression and locking of lunar soil samples

Abstract

The invention relates to a storage container for lunar soil samples realized by three-axis compression and locking with a variable inner diameter, comprising an upper sealing cover, an outer barrel, an elastic inner barrel, an inner diameter shrinking wedge, an annular linkage mechanism, an axially tightening elastic member, and an elastic inner barrel Sleeved in the outer barrel, the ring linkage mechanism is set between the elastic inner barrel and the outer barrel; the bottom wall of the outer barrel is provided with a slope, the lower end of the ring linkage mechanism is in contact with the slope and can move relative to the slope, and the upper end of the ring linkage mechanism is in contact with the inner diameter contraction wedge The wedge-shaped slope of the block is in contact with and can move relative to the shrinking wedge of the inner diameter; one end of the axially tightening elastic member is connected with the bottom wall of the outer barrel, and the other end is fixed with a slider that can seal and slide in the elastic inner barrel; the upper sealing cover is fastened On the top of the outer barrel, and by squeezing the inner diameter contraction wedge, the upper and lower ends of the ring linkage mechanism slide along the wedge-shaped slope and the slope respectively, so as to realize the radial contraction of the elastic inner barrel, and at the same time compress the axially tightening elastic member. The invention can preserve the original bedding information of lunar soil samples as much as possible.

Description

technical field [0001] The invention relates to the technical field of return packaging and storage of celestial body samples, in particular to a storage container for realizing triaxial compression and locking of lunar soil samples with a variable inner diameter. Background technique [0002] The U.S. celestial sample return packaging technology was first developed in the Apollo program in the 1960s. A series of Teflon-based packaging bags were developed to address many scientific issues such as element and isotope analysis and organic composition determination after the return of lunar samples. And the combined sample packaging system of stainless steel sample tube and aluminum sample box. The sampling of the Apollo program in the United States is based on the manual screening and collection of samples by astronauts, and manual packaging; at the same time, it meets the scientific needs of airtight return and subsequent low-background testing of a large number of different ...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the existing lunar soil sample storage container does not have the function of maintaining the sample sequence, and cannot effectively preserve the bedding information of the lunar soil sample, and the vibration during transportation has a great influence on the sample bedding
