Abstract

The invention discloses a low-impact space butt joint electromagnetic sealing device which comprises a pole shoe assembly, a magnetism isolating ring, a permanent magnet and magnetic fluid which are arranged at a butt joint opening of a first aircraft, and a corrugated pipe, a base, a telescopic part and a magnetism conducting shaft which are arranged at a butt joint opening of a second aircraft.The pole shoe assembly comprises at least two pole shoes, and a plurality of pole teeth are arranged on the pole shoes. And a permanent magnet is arranged between every two adjacent pole shoes. A magnetic isolation ring is arranged on the side, away from the second aircraft butt joint opening, of the pole shoe assembly, and the inner circle face of the permanent magnet is matched with the adjacentside faces of the two adjacent pole shoes to form a containing space. The base is connected with the inner circle face of the shell of the second aircraft docking port, the telescopic part is fixedlyconnected to the base, and the output end of the telescopic part is connected with the magnetic conductive shaft. The base, the telescopic part and the magnetic conductive shaft are all hollow and are matched to form a cavity with openings in the two ends, the corrugated pipe is located in the cavity, the first end extends out of the cavity to be connected with the side, away from the magnetic conductive shaft, of the base, and the second end is connected with the inner wall face of the magnetic conductive shaft.

Description

technical field [0001] The invention belongs to the field of space docking of spacecraft, in particular to a low-impact space docking electromagnetic sealing device. Background technique [0002] Docking mechanism technology refers to the technology that can form two aircrafts into a structural whole through contact, buffer, capture and rigid connection in space. Among them, the aircraft waiting for docking on the orbit is called the target aircraft, and the aircraft that docks with the target aircraft through a series of orbit changes and other motion controls is called the active aircraft. All space powers, including my country, are developing a new generation of spacecraft space docking systems with typical technical characteristics such as low impact, high reliability, standardization, multi-functionality, light weight, high efficiency, and intelligence. Flexible docking, the impact load during the docking contact process is small, and the structure of the new generation...
