Impacting type penetrating device

Abstract

The invention belongs to the field of planet probes, and particularly relates to an impacting type penetrating device, comprising a shell, a mass block and an impacting hammer; a capturing and releasing sleeve is driven by a direct current motor, so as to compress a drive spring; when the drive spring is compressed to be in contact with a releasing sleeve, the impacting hammer impacts the shell under an elastic force action, and at the moment, an impact force is much larger than an external action force; meanwhile, the mass block is subjected to the action of a brake spring on the tail, the amount of movement is small, secondary impacting is generated when an initial state is recovered, and the movement of the penetrating device in a vertical direction is efficiently realized; and after the process is circulated, the penetrating device can reach a predetermined depth. A self-drive manner is adopted, the penetrating device can penetrate into a ground layer without intervention of other devices; a linear drive manner is adopted, a clamping device is not needed, and no lots of heat is generated in work; and the penetrating device is light in whole weight, works reliably and has important significance in the aspect of planet surface exploration.

Description

technical field [0001] The invention belongs to the field of planet probes, in particular to an impact penetrator. Background technique [0002] With the development of aerospace technology, people are full of curiosity about the evolution of the planet, and the detection of resources is becoming more and more urgent. In recent decades, a large number of spacecraft have been launched to explore outer space, and these pioneer missions have greatly increased human knowledge of the planet. But most of them are observed by satellites in orbit. The next important detection task is to directly detect the geological characteristics of the planet. [0003] Analysis of a planet's structure, chemistry, electromagnetic fields, thermal energy, and mineral properties requires sampling it. Traditional techniques use rotary drills for sampling, requiring specialized equipment to provide positive pressure to achieve drilling. During the drilling process, the rover needs to remain station...
