Claim 9:
10. An implementation method of the bottom touching assisting device suitable for the deep-sea submersibles according to claim 2, comprising the following steps:
step 1, when the deep-sea submersible moves to seabed, the rotary drive component drives the third gear to rotate, the third gear drives one of the worms to rotate, and the other worm rotates synchronously under drive of the synchronous rotator;
step 2, when the worm rotates, the worm drives the worm wheel to rotate, so as to rotate the first rotating shaft and the second gear, and further drive the second ring gear to rotate;
step 3, the prism and the second ring gear are pressed through the pressing mechanism, so as to make the friction wheel cling to a top of the first gear; when the second ring gear rotates, the prism drives the friction wheel to rotate, the friction wheel drives the first gear to rotate, and through cooperation of the first gear and the first ring gear, the threaded sleeve rotates synchronously;
step 4, because the threaded sleeve and the support column are in threaded connection, when the threaded sleeve rotates, the support column moves in the vertical direction, so that a bottom end of the support column protrudes from the mounting box body;
step 5, when the seabed has a flat surface, the bottom ends of the four support columns make contact with the seabed at the same time; when the seabed has an uneven surface, the bottom ends of some of the support columns first come into contact with the seabed, these support columns stop moving downwards, and rotation of the threaded sleeve is resisted, so that the first ring gear and the first gear stop rotating, and the friction wheel rotates relative to the first gear; and
step 6, the rest of the support columns which are not in contact with the seabed continue to move downwards until the bottom ends of all the support columns are in contact with the seabed.
