Multi-point multi-time sampling executing mechanism suitable for frozen soil type extraterrestrial star soil

Abstract

The invention discloses a multi-point multi-time sampling executing mechanism suitable for frozen soil type extraterrestrial star soil, and relates to the field of deep space sampling detection. According to the environmental characteristics of the extraterrestrial stars and the distribution characteristics of the frozen soil type extraterrestrial star soil, in combination with the sampling and detecting requirements of the extraterrestrial star soil, the multi-point multi-time sampling executing mechanism suitable for the frozen soil type extraterrestrial star soil is provided. According to the scheme, the mechanism needs to be carried on a detector body and mainly comprises a core fixing mechanism, a core breaking mechanism, a two-way lead screw, a drill rod, a drill bit, a core breakingmechanism guide sleeve and the like. Under driving of two external motors, drilling action of extraterrestrial star soil is achieved through the drill bit and the drill rod; fixed-point coring, coreshearing and cutting, in-situ transferring and sample core spitting actions on frozen earth extraterrestrial star soil are achieved through design between the core fixing mechanism and the core breaking mechanism and matching of motion parameters. Through the transfer of the detector, the functions of multi-point multi-time sampling of different sampling points and the like are realized. At present, the scheme is verified by a frozen soil type extraterrestrial star soil simulation test, and the sampling effect is good.

Description

technical field [0001] The invention relates to a multi-point and multiple-sampling actuator suitable for frozen soil alien soil, and belongs to the technical field of multi-point and multiple sampling of frozen soil alien soil. Background technique [0002] In the process of deep space exploration, the detection target of extraterrestrial celestial bodies has shifted to "retracing the origin of life, improving the understanding of celestial bodies, and building a future home". Water resources are becoming more and more important for the study of the origin of life and the future development of deep space resources for human beings Therefore, the detection of water resources in extraterrestrial celestial bodies has attracted widespread attention from various countries, and water resources in extraterrestrial celestial bodies mainly exist in the form of frozen soil. The research on the sampling technology of extraterrestrial celestial bodies, permafrost and extraterrestrial s...

AI Technical Summary

Problems solved by technology

[0004] In summary, the traditional extraterrestrial soil sampling actuators cannot meet the needs of multi-point and multiple sampling missions of permafrost extraterrestrial soils. It is necessary to design a new type of sampling actuator to meet the mission requirements of the follow-up deep space exploration field.
