The invention discloses an electric permanent magnet butt joint and separation device and a butt joint and separation method thereof. The device comprises a first electric permanent magnet butt jointmechanism and a second electric permanent magnet butt joint mechanism, and each of the first electric permanent magnet butt joint mechanism and the second electric permanent magnet butt joint mechanism comprises yokes, a permanent magnet, an excitation coil and a control power supply. The magnet exciting coil is arranged on the periphery of the permanent magnet, the yokes are arranged at the two ends of the permanent magnet, and the control power supply is electrically connected with the magnet exciting coil. The problems that in the prior art, plume pollution exists in a butt joint mechanism,energy consumption is high, and a locking device is complex in structure are solved.
Description
technical field [0001] The invention relates to the technical field of docking, in particular to a precise electro-permanent magnetic docking and separating device and a docking and separating method that can repeatedly realize docking, separation and locking. Background technique [0002] In the technical fields of long-distance docking and controllable speed at the end of the large-tolerance docking mechanism, the use of thrusters based on recoil to achieve docking is the mainstream method of docking technology. This technology is mature, reliable, and has been widely used in engineering practice. application. However, there are still two main problems with this approach. One is that the propellant dose during the docking process directly affects the working life of the docking mechanism; the other is that in order to reduce the docking speed, the thrust in the opposite direction must be used for braking, which will not only cause plume pollution, but also cause disturban...
