RESCUE SUBMERSIBLE COMPLEX AND METHOD OF PERFORMING WORK BY THIS COMPLEX Russian patent published in 2000 - IPC

FIELD: rescue facilities used for raising sunken vessels. SUBSTANCE: rescue submersible complex includes three submarines equipped with means for motion, submergence and surfacing together with rescue object. Hull of each submarine is made from torous rings welded together; torous rings are tubular in section. One submarine is provided with lattice-like framework of supporting device over entire length; ball-like hollow wheels are secured to it from below. Second and third submarines are equipped with propellers. Secured between branch pipes of propellers over entire length of these submarines are hollow fins - cantilevers for turning, gripping, raising and carrying the object being rescued. At point of location of object to be rescued, submersible complex is submerged. Second and third submarine start operate their propellers turning and gripping the object by their fins-cantilevers. First submarine takes position below second third submarine raising the object and is coupled with them. EFFECT: extended functional capabilities of submersible complex. 3 cl, 7 dwg
