Abstract

The invention provides a three-leg supporting asteroid surface anchoring device based on an impact type ultrasonic drill. A support of the anchoring device is installed at the bottom of a detector, wherein the three branches of the support are evenly arranged at intervals of 120 degrees, the supporting legs are installed at the tail end of each branch of the support, a supporting foot pad is arranged at the bottom of each supporting leg and used for improving the landing stability of the supporting leg, the interior of each supporting leg is of a hollow structure, a drilling anchoring mechanism is installed in each supporting leg, and one end of the drilling anchoring mechanism penetrates out of the supporting foot pad. The problem is solved that an asteroid detector in the prior art cannot be stably fixed on the surface of an asteroid after landing, and because the attractive force on the surface of the asteroid is very small, the detector is easy to bounce during landing and samplingwork. The three-leg type supporting asteroid surface anchoring device based on the impact type ultrasonic drill is provided, the three anchoring supporting legs are evenly arranged at intervals of 120 degrees to form a force closed structure, stability is high, the reaction force of the impact type ultrasonic drill is small, and the detector is not prone to bounce.

Description

technical field

[0001] The invention relates to a three-leg support asteroid surface anchoring device based on an impact ultrasonic drill, which belongs to the field of surface attachment of asteroid detection. Background technique

[0002] Asteroid detection has gradually become the main development direction of space exploration in the next few years. Because asteroids have the characteristics of irregular shape, uncertain surface topography and low surface gravity, it is difficult for asteroid probes to attach to the surface of asteroids for scientific detection. Most of the asteroid probes currently launched detect asteroids in the form of orbiting, fly-by, and "one-touch and leave". No probe has successfully attached to the surface of the asteroid. Although the Japanese Hayabusa probe using the "one-touch and leave" method collected asteroid surface samples and returned them to Earth, due to the very small number of samples obtained, it was impossible to conduct more d...
