Problems solved by technology

The reliability of the dynamic seal at a large depth is far inferior to that of the static seal. In addition, the joint structure of the dynamic seal is complex. When the joint diameter is large, the processing technology is poor, and sometimes it cannot be realized.

Abstract

The present invention discloses one kind of underwater butt-joint device, which includes one fixing skirt with flanges, one direction skirt, one angle skirt with flanges, driving and sealing mechanisms set between the fixing skirt and the direction skirt and between the direction skirt and the angle skirt, top covers with mounted locking oil cylinder, composite bearings, one hydraulic motor, outer gear rings outside the top covers, and driving gears. The driving and sealing mechanism consists of hydraulic motor, locking oil cylinder, driving gear, composite bearing seat and O-ring. The present invention is applied for butt-joint operation in rescue of life boat. It can realize reliable sealing in deep operation.

Description

(1) Technical field [0001] The invention relates to a personnel rescue device for an underwater submarine, in particular to an underwater docking device used for submarine rescue and marine development operations. (2) Background technology [0002] At present, underwater docking technology is mainly used in the transfer of submarine staff and materials during submarine rescue and ocean development operations. The early deep-submersible lifeboats all used fixed docking skirts. Although the structure of this device is simple, it requires high maneuverability of the boat itself during rescue operations. When the transverse and pitch angles of the wrecked boat are large, underwater docking is the quite difficult. In recent years, a rotating docking skirt has appeared abroad. Using this device can ensure that when the wrecked boat has a large inclination angle, the lifeboat remains horizontal when docking, and can resist the sea current at the best angle during the docking opera...
