Embodiment

[0072] Such as figure 1 As shown, a failed satellite capture and docking device includes a bracket 1, the bracket 1 is a hollow cylindrical structure, and a plurality of weight-reducing slots are opened on the bracket 1, and the weight-reducing slots can also facilitate the operator to pair the The internal structure of the frame is installed and maintained. The first flange 10 and the second flange 11 are respectively fixed on the upper and lower ends of the bracket 1. The bracket 1 is fixed on the surface of the mission star 12 through the second flange 11. The axis of the bracket 1 It is arranged coaxially with the axis perpendicular to the fixed surface of the mission star 12 . Controller 13 is also fixedly installed on support 1 .

[0073] A lasso capture mechanism 2 and a buffer docking locking mechanism 3 are installed on the bracket 1 from inside to outside. The two-layer ring structure formed by the noose capture mechanism 2 and the buffer docking locking mechanism 3...

Abstract

The invention discloses a failure satellite capturing and docking device which adopts a lasso capturing mechanism to capture a target satellite, then drives the captured target satellite to approach a task satellite, and realizes docking between the task satellite and the target satellite through a buffer docking locking mechanism. In addition, a controller is additionally arranged in the failure satellite capturing and docking device, and the capturing and docking process is intelligently controlled. The device integrates capturing, docking, locking and releasing, has the advantages of being large in capturing tolerance, high in capturing success rate and firm in docking, can reduce the attitude deviation between two satellites in the approaching process of the two satellites after capturing, improves the docking accuracy, can repeatedly implement multiple capturing tasks, and is high in practicability. The invention further discloses a failure satellite capturing and docking method based on the failure satellite capturing and docking device.

Description

technical field [0001] The invention belongs to the technical field of capturing failed satellites, and in particular relates to a device and method for capturing and docking failed satellites. Background technique [0002] With the advancement and development of science and technology, the number of artificial satellites launched by humans into space is increasing. However, with the accumulation of time, the number of satellites in space that have reached the working age or failed to continue to work is gradually increasing. This type of invalid or faulty satellite poses a threat to the normal working satellite. At present, most of the processing methods for this type of satellite are to change to a non-working orbit through the control of the propulsion system. However, some satellites cannot be de-orbited normally due to faults. There are also some satellites where the propellant fuel is exhausted, and other components can still work normally, which greatly reduces the se...
