Abstract

The invention relates to an anchor positioning system for detecting a lander, in particular to the anchor positioning system for detecting a planetoid lander. The anchor positioning system solves the following problems of a telescopic sleeve connecting and positioning system: an anchor bill is inclined when in incidence and transverse impact load is acted on the lander, so as to damage instruments at the inner part of the lander; a moving part of a telescopic sleeve is changed in quality during the incidence, so as to cause difficulty in estimating initial emission energy. An advancing mechanism is fixedly arranged on the side face of a cable box body, a winding mechanism is fixedly arranged on a rear end cover of the cable box body, a locking and unlocking mechanism is fixedly arranged on a right shell body of the winding mechanism, a connecting rope is stored in the cable box body, one end of the connecting rope is fixed on an anchor rod pin, and the other end of the connecting ropeis fixedly connected with a winding reel. A winding motor and an unlocking motor are connected with a pin socket by a lead wire. The anchor positioning system can also be used not only for detecting the lander of a small celestial body with weak surface gravitation such as the comet and the like, but also for automatic operation of a robot in dangerous environments.

Description

technical field [0001] The invention relates to an anchor positioning system for lander detection, belonging to the technical field of deep space detection and positioning systems. Background technique [0002] The development of space technology has made it possible for humans to send probes to some planets in the solar system, and land on the surface of some planets to retrieve soil and rock samples, and to understand and use planets through scientific experiments. So far, humans have landed on the surface of the moon and Mars, and successfully retrieved lunar soil and rock samples. In addition to the moon and Mars, humans have also launched landers to Venus, Jupiter, asteroids, and comets. With the advent of the 21st century, deep space exploration technology, as an important means for human beings to protect the earth, enter the universe and find new living homes, has attracted great attention from various countries in the world. Deep space exploration will be an impor...
