Embodiment Construction

[0050] Such as figure 1 , figure 2 As shown, a locking and releasing device suitable for the docking of satellite docking rings includes a mounting bracket 27, a ring bracket 26, a spring damper 35, a transmission mechanism 28 and a holding and pressing mechanism. The holding and pressing mechanism includes a rotating seat 2. Holding mechanism and pressing mechanism. The holding and pressing mechanism is fixed on the ring bracket with 120° equiangular distribution, and there are three groups in total, which are used to hold and press the docking ring of the target satellite to realize the rigid connection between the capture satellite and the target satellite.

[0051] The mounting bracket 27 is a plurality of support columns connected with the captured satellites, the bottom of the support columns has a horizontally extending connecting portion and has a positioning hole.

[0052] The ring support 26 includes a lower disc 33 and an upper disc 34 .

[0053] Such as Figur...

Abstract

A locking release device applicable to satellite docking ring docking comprises a circular bracket (26), a transmission mechanism (28) and more than two sets of holding and compressing mechanisms. The circular bracket (26) is fixedly connected to a captured satellite. Each holding and compressing mechanism comprises a holding mechanism, a compressing mechanism and a rotating seat (2); the holding mechanism comprises a compressing member (1), a movement transfer member (8), a translation guide rail (7) and a cross pin shaft (5), and the compressing member (1) does radial or axial movement to compress a target satellite and draw the target satellite closer; and the compressing mechanism comprises a compressing plate (6), a compressing plate seat (9), an ejector pin (4) and an ejector pin guide rail (3), wherein up-and-down movement of the ejector pin (4) along the ejector pin guide rail (3) makes the compressing plate (6) rotate relative to the compressing plate seat (9) through four-stage pair connection, and one end of the compressing plate (6) is used for compressing or releasing a target satellite docking ring. With the device, a target satellite can be held, pulled closer, locked, released or retreated.

Description

technical field [0001] The invention relates to a satellite docking locking device. Background technique [0002] The failure or failure of a spherical geostationary orbit (GEO) satellite in orbit will cause a huge waste of space resources. After it is captured and rigidly connected, it can be repaired or de-orbited, so that the mission capability of the faulty satellite can be continued or released. Important track resources can obtain very important economic and social benefits. Therefore, the design of the satellite docking mechanism is the core component of satellite capture and one of the important factors affecting whether it can be repaired normally. [0003] Since the GEO satellites currently in orbit and under research are not designed to receive in-orbit services, they do not have a cooperative docking interface. Therefore, in combination with the rescue service and de-orbit operation requirements for this type of satellite, it is necessary to use a capture mecha...
