Bionic obstacle-avoidance large-depth interstellar sampler and sampling method

Abstract

The invention relates to bionic obstacle-avoidance large-depth interstellar sampler and a sampling method. The bionic obstacle-avoidance large-depth interstellar sampler comprises a driving outer sleeve, a material storage bin and an excavating head, the material storage bin is installed in the driving outer sleeve, the excavating head is installed at the bottom of the driving outer sleeve, and the driving outer sleeve comprises a plurality of outer sleeve scale layers which are vertically arranged. The material storage bin comprises a plurality of vertically-arranged material storage bin units and a petal type bin bottom located at the bottom, the excavating head is an open-close petal-shaped structure, anti-drag protrusions are arranged on the surfaces of the driving outer sleeve and the excavating head, the driving outer sleeve, the material storage bin and the excavating head are all made of shape memory materials, and heating circuits are arranged in an inner portion. A temperature control module is used for controlling the temperatures of different directions of the driving outer sleeve, the outer wall and the bin bottom of the material storage bin and the excavating head, deformation is driven by a program, and therefore the excavating head is driven to advance and avoid obstacles. The interstellar sampler can realize large-depth interstellar sampling with accurate orientation and positioning, can effectively reduce a sampling resistance and save energy, and is simpler, lighter, more efficient and more energy-saving in structure compared with a traditional interstellar soil sampler.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an interstellar sampler and a sampling method. Background technique [0002] Aerospace is a frontier project for human beings to explore nature, and it is a cause that must be developed for my country to become a technological power. Among them, interstellar soil sampling is one of the important steps in my country's aerospace research. Interstellar soil, that is, the soil on the surface of an alien planet, is generally formed by meteorite impact, crushing and lithification. By studying interstellar soil samples, not only can we learn about resources such as mineral deposits on alien planets, but we can also explore the development history of alien planets, and even further verify whether there are alien creatures. Therefore, taking interstellar sampling and obtaining interstellar soil samples is an important and necessary step for human beings to understand the universe and ...

Problems solved by technology

However, the quality of the components that can be carried on the spacecraft is strictly limited. The greater the mass of the components, the more fuel is needed, and the greater the cost.

The existing mechanical power interstellar sampler is expensive, the machine is heavy, and consumes a lot of energy; moreover, sampling obstacles cannot be avoided during the sampling process, and the sampling quality is difficult to guarantee
