Bionic Obstacle-Avoidable Large Depth Interstellar Sampler and Sampling Method

Abstract

The invention relates to a bionic obstacle-avoidable large-depth interstellar sampler and a sampling method, comprising a driving casing, a storage bin and a digging head, the storage bin is installed inside the driving casing, the digging head is installed at the bottom of the driving casing, and the driving casing It includes several vertically arranged coat scale layers, and the storage bin includes several vertically arranged storage bin units and a petal-shaped bin bottom at the bottom. The drag-reducing protrusions, the driving jacket, the storage bin, and the digging head are all made of shape memory materials, and the built-in heating circuit controls the temperature of the driving jacket in different directions, the outer wall of the storage bin, the bottom of the bin, and the digging head through the temperature control module. Drive deformation to drive the digging head forward and avoid obstacles. The invention can realize large-depth interstellar sampling with precise orientation and positioning, can effectively reduce sampling resistance, and save energy. Compared with traditional interstellar soil samplers, the structure is simpler, lighter, more efficient and energy-saving.

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
