MAGNETICALLY-CONTROLLED POSITIONING RESCUE AND SALVAGE SYSTEM FOR EMERGENCY RESCUE

摘要

A magnetically-controlled positioning rescue and salvage system for emergency rescue. The magnetically-controlled positioning rescue and salvage system comprises a portable device (1) and a rescue device (2). The portable device (1) comprises a raised groove (121), a hook fixing groove (122), a first electro permanent magnet (125), and a position-indicating radio beacon (1262). The rescue device (2) comprises a rescue cable (21), a spring safety latch device (222), a recessed groove (223), and a second electro permanent magnet (225). The position-indicating radio beacon (1262) is used for releasing a radio distress signal and a positioning signal. The portable device (1) and the rescue device (2) are automatically bound by means of attraction force between the first electro permanent magnet (125) and the second electro permanent magnet (225), and the automatic bound state is stabilized by the mechanical coupling between the raised groove (121) and the recessed groove (223) and the mechanical coupling between the hook fixing groove (122) and the spring safety latch device (222). The magnetically-controlled positioning rescue and salvage system for emergency rescue is easy to operate; and the problems of high risk and low efficiency of the existing rescue mode are resolved by means of the magnetic field force and mechanical coupling structure.
