step one, preparation work:
after entering a target sea area through Beidou navigation, a platform operator enters an area to be anchored, and safety inspection and preparation before anchoring are carried out;
respectively checking a plurality of groups of rapid anchor frame arranging devices symmetrically arranged at two sides of a ship body (6) in the advancing direction; checking whether the position of the large-gripping anchor (7) and the long anchor chain (8) which are arranged on the anchor frame body (1) is correct or not;
starting an anchor frame lifting device (4) to lift the rear end of the anchor frame body (1) to adjust an ideal anchoring angle;
secondly, anchoring work:
the quick laying anchor frame device on one side of the ship body (6) close to the shore breaks down simultaneously, and in order to avoid mutual interference of a plurality of large holding power anchors (7) on the same quick laying anchor frame device during breaking down, the plurality of large holding power anchors (7) on the same quick laying anchor frame device are sequentially thrown into the sea;
after anchors on the quick anchor frame laying device on the shore side of the ship body (6) are all thrown into the sea, the ship body (6) sails to a position above an anchor point on the shore side by means of self propeller power through Beidou navigation guidance;
the quick laying anchor frame device on one side of the back of the ship body (6) is anchored simultaneously, and in order to avoid mutual interference of a plurality of large holding power anchors (7) on the same quick laying anchor frame device during anchoring, the plurality of large holding power anchors (7) on the same quick laying anchor frame device are sequentially thrown into the sea;
thirdly, ending:
after anchors on the quick anchor frame arrangement device on the back side of the ship body (6) are all thrown into the sea, the ship body (6) adopts Beidou navigation to navigate to a final berthing position by means of self propeller power;
the length of the mooring rope is adjusted through the anchor machine, so that the long anchor chain (8) reaches proper pretension;
and (3) starting the anchor frame lifting device (4) to lower the rear end of the anchor frame body (1) to the initial height so as to complete anchor distribution.
8. A method of deploying a small topside marine anchor as set forth in claim 7 wherein: in the second step: the steps of throwing a plurality of large holding power anchors (7) on the same rapid laying anchor frame device into the sea in sequence are as follows:
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 large holding power anchor (7) at the lowest end to slide downwards along a bottom plate (101), enabling a connecting pin buckle (9) and a long anchor chain (8) connected with the large holding power anchor (7) to pass through a channel (102), and realizing throwing out of the large 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 large-holding-force anchor (7) behind the thrown large-holding-force anchor (7) is carried out;
closing an anchor stop lever mechanism (2) and an anchor chain stop lever mechanism (3) corresponding to a large-gripping-force anchor (7) at the rear of the anchor in the arrangement direction, so that the large-gripping-force anchor (7) slides downwards along a bottom plate (101), and a connecting pin buckle (9) and a long anchor chain (8) connected with the large-gripping-force anchor (7) pass through a channel (102) to throw out the large-gripping-force anchor (7);
repeating the steps, and throwing out the large-gripping anchors (7) on the rest anchor frame body (1).
