Lunar soil sample container configuration convenient for low-gravity transfer

Abstract

The invention discloses a lunar soil sample container configuration convenient for low-gravity transfer. The lunar soil sample container configuration comprises a lunar soil sample container configuration body (6), a weak guiding device (5) and a sealing container (7), wherein the lunar soil sample container configuration body (6) is of a thin-wall ring cylindrical configuration; a guide conical section is arranged on the outer wall of the lunar soil sample container configuration body (6); an inner wall guide matching section (4) is arranged on the inner wall of the lunar soil sample container configuration body (6); the weak guiding device (5) and the sealing container (7) are both mounted on a fixing structure; the lunar soil sample container configuration body (6) can go downards alongcommon axis of the weak guiding device (5) and the sealing container (7).

Description

technical field [0001] The invention relates to a configuration of a lunar soil sample container which is convenient for low-gravity transportation. Background technique [0002] The scientific goal of my country's third-phase lunar exploration project planning is to obtain lunar samples and return them to Earth. According to the mission plan, the lunar soil samples obtained by drilling are first packaged in the lunar soil sample container. After the packaging is completed, the lunar soil sample container is separated from the sample acquisition mechanism and transferred to the sealed container directly below it. Because whether the lunar soil sample container can be reliably transported into the sealed container is related to the success or failure of the lunar sampling mission, it is a single point of failure of the system, and the lunar surface is a low-gravity environment, therefore, the configuration of the lunar soil sample container must be convenient for the containe...

AI Technical Summary

Problems solved by technology

[0003] Before being separated from the sample acquisition mechanism, there is a certain positional deviation between the axis of the lunar soil sample container and the axis of the sealed container located below it. Therefore, the lunar soil sample container cannot be accurately transferred to the sealed container by setting a precise guide device , but it is necessary to adopt a method of weak guiding constraints to complete the transmission of the lunar soil sample container, which requires that the configuration of the lunar soil sample container can adapt to the interference caused by the axis deviation during the transmission process and reliably transmit it to the sealed container; The configuration of the lunar soil sample container must also ensure sufficient volume to contain the lunar soil sample, and the reliable packaging of the lunar soil must be ensured so that the lunar soil sample does not leak during the transmission process; the lunar soil sample container is directly exposed to the space environment. High and low temperature resistance, radiation resistance and other performance requirements are strict; the third phase of the lunar exploration project carried out the lunar sampling and return mission for the first time, and there is no similar product to learn from

[0004] In summary, for the new task of lunar sample return, there are no mature design products for the sample container used to hold the lunar soil. It is necessary to design a new lunar soil sample container to complete the lunar soil sample transfer action under low gravity.
