step three, ending work:
after anchors on the quick anchor arrangement device on one side of the back shore of the ship body (6) are thrown into the sea, the ship body (6) navigates to a final berthing position by adopting Beidou navigation and relying on the power of a propeller of the ship body;
the length of the mooring cable is adjusted through the anchor machine, so that the long anchor chain (8) achieves proper pre-tension;
and starting the anchor frame lifting device (4) to lower the rear end of the anchor frame body (1) to the initial height, and finishing anchor distribution.
8. The method for arranging the anchor suitable for the small-topsides ship as claimed in claim 7, wherein the method comprises the following steps: in the second step: the method comprises the following steps of sequentially throwing a plurality of high holding power anchors (7) on the same quick anchor frame arrangement into the sea:
firstly, closing an anchor stop lever mechanism (2) and an anchor chain stop lever mechanism (3) at the lowest end of an anchor frame body (1), enabling a high-holding-power anchor (7) at the lowest end to slide downwards along a bottom plate (101), and enabling a connecting pin buckle (9) connected with the high-holding-power anchor (7) and a long anchor chain (8) to pass through a channel (102) to throw out the high-holding-power anchor (7);
then, the ship body (6) runs for a certain distance along the advancing direction, and then the throwing action of the high holding power anchor (7) behind the thrown high holding power anchor (7) is carried out;
closing an anchor stop lever mechanism (2) and an anchor chain stop lever mechanism (3) which correspond to a high-holding-power anchor (7) behind the anchor arrangement direction, enabling the high-holding-power anchor (7) to slide downwards along a bottom plate (101), enabling a connecting pin buckle (9) connected with the high-holding-power anchor (7) and a long anchor chain (8) to pass through a channel (102), and enabling the high-holding-power anchor (7) to be thrown out;
repeating the steps, and throwing out the high holding power anchor (7) on the rest anchor frame body (1).
