A Receiving Supplementary Connector with Fault Isolation Function

Abstract

The invention provides an acceptable replenishing contact with a failure isolation function. The replenishing contact comprises an outer shell and a contact structure, wherein the contact structure is mounted on a receiver through the outer shell, and the contact structure is arranged in the outer shell and can axially move along the inner side of the outer shell; limiting sliding blocks are arranged in the inside wall of the outer shell, and the limiting sliding blocks radially slide and extend outside the inner surface of the outer shell along the contact structure; sliding push rods are arranged on the end surface, which is opposite to gas-liquid floating disconnectors, of the outer shell, one end of each sliding push rod extends outside the end surface of the outer shell, the other end of each sliding push rod is abutted to the limiting sliding block, and the contact surfaces of the limiting sliding blocks and the sliding push rods are bevels; a limiting structure is arranged on one circle of the outer surface of the contact structure. The replenishing contact disclosed by the invention can smoothly complete the pipeline docking operation of multiple groups of gas-liquid floating disconnectors, and under the condition that a certain group of the gas-liquid floating disconnector is jammed, the docking of other gas-liquid floating disconnectors and corresponding pipelines is not influenced, and the subsequent high pressure gas-liquid replenishing operation, normal disconnection operation and the like are not influenced.

[0002] With the increasing demand for on-orbit gas-liquid replenishment of spacecraft, it is especially required to overcome the position and attitude deviation of two spacecraft after the rigid docking is completed under the limited load space and weight range, relying on a single motor to drive multiple A group of gas-liquid floating disconnectors realize the connection of multiple groups of gas-liquid pipelines between two aircrafts, and then can complete the gas-liquid transmission supplementary operation of tens of MPa in the pipeline; During the connection process of the liquid circuit, there is a possibility that one or several supplementary joints are difficult to complete the deviation self-adaptation, and a fault occurs that the joint or joints of the supplementary joint or several lines are stuck, and the occurrence of this fault will directly affect other gas systems. The connection of the liquid pipeline and the subsequent supplementary operation

[0003] At present, the content of gas-liquid replenishment for space vehicle on-orbit service is in the initial preliminary research stage. There is no ideal solution that can use a single motor to drive multiple groups of gas-liquid floating disconnectors in a small layout space and weight range. In the case of a group of gas-liquid floating disconnectors being stuck, it can complete the connection with other pipelines and the subsequent high-pressure gas-liquid replenishment and normal disconnection operations without affecting other gas-liquid floating disconnectors
