A small tension anti-winding slow-release rope retractable mechanism

Abstract

The invention belongs to the field of space debris cleaning, and in particular relates to a rope retracting and releasing mechanism with low tension, anti-winding and slow-release. Including wire storage mechanism, power source, wire arrangement, gear transmission system, speed measurement system and slow release mechanism; When the rope on the wire mechanism is pulled out, the scroll spring type power source stores energy, and the diameter of the gear corresponding to the scroll spring type power source is larger than the diameter of the gear corresponding to the wire storage cylinder in the wire storage mechanism; the wire storage cylinder of the wire storage mechanism The end opposite to the gear is provided with a slow release mechanism; the speed measuring system includes Hall elements and magnets evenly distributed on the periphery of the power source; the speed measuring system transmits the measurement results to the cable arrangement to control the cable arrangement. The invention maintains the tension on the rope by relying on the mechanical structure, reduces the complexity of control from the perspective of hardware design, and increases the working stability and reliability of the rope retracting mechanism.

Description

technical field [0001] The invention belongs to the field of space debris cleaning, and in particular relates to a rope retracting and releasing mechanism with low tension, anti-winding and slow-release. Background technique [0002] In addition to the spacecraft that are still in normal use in space, there are still invalid man-made objects left in outer space, that is, space debris. At present, the number of space debris has reached tens of thousands, and these space debris are always threatening the safety of working satellites. Therefore, it is urgent to clean up space debris. In the field of space debris removal, flexible capture deorbit is an emerging deorbit technology. This technology wraps the target with a structure such as net or cloth and forms a reliable connection with the space tugboat through a rope, and then the space tugboat tow the target to perform the task of de-orbit clearance. In the process of de-orbiting, it is necessary to ensure that the rope is ...

AI Technical Summary

Problems solved by technology

[0004] 1. The entire mechanism contains many electronic components, and its operation reliability is low in harsh environments such as space vacuum, high-energy particles, cold black, solar radiation, and magnetic fields.

[0005] 2 Electronic components need to be powered all the time, consume more power, and are not friendly to space tugs with limited power storage

[0006] 3 no wiring mechanism

In various derailment schemes, the length of the rope ranges from tens of meters to hundreds of meters. If there is no cable arrangement mechanism, the ropes will squeeze each other on the wire storage barrel and collapse during the complete winding process of the ropes. Cause a greater impact on the system and bring greater difficulty to the system control
