A DEVICE FOR HOLE PLUGGING

摘要

The device plugs holes in the metallic hulls of vessels. Its sealing capacity is more reliable and simpler, which accelerates the hole-plugging process. The device consists of a drum (1) and an adhesive pad (2). The pad areas (2) - between one lower and two upper canvases (13) and in special sockets (22) - engage pulse magnets (23), each comprising a magnetic core (25) and a bobbin (26) with a first (27) and second (28) terminals. All first terminals (27) are electrically switched to the first pole of a power supply source (12) and all second terminals (28) - to the second pole. The front part (3) of the adhesive pad holds impulse-connecting magnets (24), whose first and second terminals are electrically switched to the third and fourth terminals of the power supply source (12) and serve as a connection to the profiled axle (5) of the drum (1).
