A multi-point and multiple sampling actuator suitable for permafrost-like alien soil

Abstract

The utility model relates to a multi-point multi-sampling actuator suitable for permafrost-like terrestrial extraterrestrial soil, which relates to the field of deep space sampling and detection. According to the environmental characteristics of extraterrestrial bodies and the distribution characteristics of permafrost-like extraterrestrial soil, combined with the sampling and detection requirements of extraterrestrial soil, a multi-point and multiple sampling actuator suitable for permafrost-like extraterrestrial soil is proposed. The solution needs to be mounted on the main body of the detector, and mainly includes a core fixing mechanism, a core breaking mechanism, a bidirectional screw, a drill pipe, a drill bit, a guide sleeve for the core breaking mechanism, etc. Realize the drilling action of the extraterrestrial soil; realize the fixed-point coring, shearing and breaking, in-situ transfer, and sampling of the permafrost-like extraterrestrial soil through the design of the core fixing mechanism and the core breaking mechanism and the matching of the motion parameters. Core spit action; through the transfer of the detector, the functions of multi-point and multiple sampling of different sampling points are realized. At present, the scheme has been verified by the frozen soil-like alien soil simulation test, and the sampling effect is good.

Description

technical field [0001] The invention relates to a multi-point multi-sampling executive mechanism suitable for permafrost-like terrestrial extraterrestrial soil, and belongs to the technical field of permafrost-like extraterrestrial soil multi-point multi-sampling. Background technique [0002] In the process of deep space exploration, the detection goal of extraterrestrial celestial bodies has turned to "trace the origin of life, improve the understanding of celestial bodies, and build future homes". Water resources are becoming more and more important for the study of the origin of life and the future development of deep space resources Therefore, the detection of water resources in extraterrestrial celestial bodies has received extensive attention from various countries, and the water resources in extraterrestrial celestial bodies mainly exist in the form of permafrost. The research on the sampling technology of extraterrestrial celestial permafrost-like 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.
