After the cable pile 27 automatically extends to the ground of the embankment, the controller 26 automatically controls the motor 24 to stop running, then the frame plate 2 hinged with the ship body 1 is rotated to the position above the bearing head 49, after the frame plate 2 contacts the bearing head 49, the rope clamping assembly on the lower surface of the frame plate 2 automatically pushes out the cable 14, and the cable 14 falls to the outer side of the cable pile 27; the structure utilizes the interaction force between the frame plate 2 and the bearing head 49 to lead the rope clamping assembly to automatically complete the arrangement of the cable 14, thus avoiding the danger of falling into water when the cable 14 is thrown manually by workers, and also completing the frame plate 2 which is convenient for people to go ashore in advance, thereby saving the time required in the whole mooring process.

And the pressure-bearing head 49 is continuously compressed downwards under the gravity action of the frame plate 2, the air assembly finishes inflating and conveys compressed air to the inside of the air inlet channel 39 and pushes the transverse shaft 42 in the first blind hole 38 in the process that the pressure-bearing head 49 is continuously pressed downwards, and the transverse shaft 42 drives the clamping jaws 37 to extend outwards; the structure utilizes the falling gravity of the frame plate 2 and the inertia to drive the inflation assembly to inflate, the inflation assembly pushes the clamping jaws 37 of the tether assembly to the upper side of the cable 14, the inflation assembly can inflate under the action of the gravity of the frame plate 2, and the inflation assembly can also buffer the falling of the frame plate 2, so that unnecessary self-damage caused by the fact that the frame plate 2 is directly hit to the pressure bearing head 49 is avoided.

After the movable jaws 37 are extended outward, the controller 26 controls the driving assembly to rotate the vertical shaft 22 counterclockwise, and the vertical shaft 22 slides the bollard 27 downward along the vertical shaft 22 inside the cylinder 18 through the screw transmission structure.

After the peg 27 rotates counterclockwise one round along the vertical shaft 22 inside the cylinder 18, the cable 14 also winds one round along the vertical shaft 22, then the controller 26 controls the motion conversion mechanism again to convert the rotation of the peg 27 along the vertical shaft 22 inside the cylinder 18 into sliding, so that the peg 27 slides down again along the vertical shaft 22 inside the cylinder 18, and when the jaw 37 enters inside the flared opening 19 during hooking the downward movement of the cable 14, the jaw 37 gradually compresses the cable 14 during the downward movement due to the inclined surface structure of the flared opening 19, and the soft pad 43 inside the spiral groove 36 cooperates with the jaw 37 to make the cable 14 wind more firmly outside the peg 27.
