The engineering ship can directly load the suction anchor 100 to sail on the sea, and when the engineering ship runs to a target position, the suction anchor 100 is hoisted by a crane on the engineering ship and slowly put on the water surface, so that the self-weight mud entering work of the suction anchor 100 is completed.
After the suction anchor 100 partially sinks under the mud surface under its own weight, the adjustment platform 200 is brought close to the suction anchor 100. Alternatively, the adjustment platform 200 is disposed on a loading ship, and the adjustment platform 200 is fixedly connected to the loading ship, and the loading ship can carry the adjustment platform 200 and sail to a target position at sea.
In addition, the adjustment platform 200 can be directly replaced by a loading ship, namely, the anchor machine 210 is also integrally arranged on the loading ship, and the using effect of the adjustment platform 200 can also be achieved.

The propulsion system is preferably, but not limited to, a plurality of propellers, and the principle and the specific process of the propulsion control system for controlling the propulsion system are the prior art, and will not be described in detail herein.
Preferably, the surface of the traction element 220 is coated with an anti-corrosion layer, which can prevent the traction element 220 from contacting with seawater for a long time to generate surface corrosion, and prolong the service life of the traction element 220.
In this embodiment, referring to fig. 3, a plurality of connectors 110 for connecting with the pulling element 220 are disposed at the edge of the upper end surface of the suction anchor 100, and the plurality of connectors 110 are spaced apart along the circumference of the suction anchor 100. The arrangement of the connector 110 provides a reliable connection position for the traction part 220, and the connector 110 is arranged on the edge of the upper end face of the suction anchor 100, when the traction part 220 pulls the connector 110, the traction part 220 can not only pull the suction anchor 100 more obviously in the tangential direction, but also increase the force arm of the tangential acting force acting on the suction anchor 100, namely the tangential torque received by the suction anchor 100 is obviously increased, and further the effect of the rotation of the suction anchor 100 around the connector is more obvious. And by arranging the connecting head 110 in a plurality, when the traction member 220 is connected with the suction anchor 100, the proper connecting head 110 can be selected to ensure that the pulling force applied to the suction anchor 100 in the tangential direction when the traction member 220 pulls the suction anchor 100 reaches the maximum value.
As a preferable scheme of this embodiment, the anchors 210 are disposed at both sides of the adjustment platform 200 in pairs, the suction anchor 100 is located between the two anchors 210, and each anchor 210 is connected to the same connecting head 110 close to or far from the adjustment platform 200 through a corresponding pulling member 220. Referring to fig. 4 to 5, fig. 4 is a schematic view showing that two anchors 210 are connected to the connecting head 110 far from the adjustment platform 200, and fig. 5 is a schematic view showing that two anchors 210 are connected to the connecting head 100 near the adjustment platform 200. Specifically, when the mooring eye plate of the suction anchor 100 deviates in one direction, the suction anchor 100 on the side away from the mooring eye plate deflection direction of the suction anchor 100 tightens the corresponding traction member 220, and the suction anchor 100 on the side close to the mooring eye plate deflection direction of the suction anchor 100 loosens the corresponding traction member 220, so that the suction anchor 100 is subjected to a tangential force opposite to the mooring eye plate deflection direction, a tangential torque opposite to the mooring eye plate deflection direction is generated, the suction anchor 100 is rotated in the direction opposite to the mooring eye plate deflection direction, and the azimuth angle of the suction anchor 100 is adjusted until the mooring eye plate is adjusted to a position facing the fan.
Alternatively, the two connection modes in fig. 4 and 5 can be switched by the relevant operator diving under water to exchange the connection position of the traction element 220 and the connection head 110.
As a preferable scheme of this embodiment, the anchors 210 are disposed at both sides of the adjustment platform 220 in pairs, the suction anchor 100 is located between the two anchors 210, one of the anchors 210 is connected to the connecting head 110 near the adjustment platform 200 through the corresponding pulling member 220, and the other anchor 210 is connected to the connecting head 110 far from the adjustment platform 200 through the corresponding pulling member 220. As shown in fig. 6 to 7, when the pulling force on the suction anchor 100 is insufficient in the above manner, the azimuth adjustment of the suction anchor 100 can be achieved using this manner. Specifically, when the mooring eye plate of the suction anchor 100 deviates in one direction, the two anchors 210 simultaneously tighten the corresponding traction members 220, so that the suction anchor 100 receives a tangential acting force in a direction opposite to the deflection direction of the mooring eye plate, a tangential torque in a direction opposite to the deflection direction of the mooring eye plate is generated, the suction anchor 100 rotates in a direction opposite to the deflection direction of the mooring eye plate, and the azimuth angle adjustment of the suction anchor 100 is realized until the mooring eye plate is adjusted to a position opposite to the center of the fan.
Unlike the connection manner in fig. 4 to 5, either one of the connection manners in fig. 6 and 7 can only achieve the angle adjustment of the suction anchor 100 along one rotation direction, specifically, when the left-side anchor 210 is connected to the connection head 110 far away from the adjustment platform 200 and the right-side anchor 210 is connected to the connection head 110 near the adjustment platform 200 in fig. 6, the two anchors 210 simultaneously tighten the corresponding traction members 220 to control the rotation of the suction anchor 100 towards the first direction; in fig. 7, when the left-side anchor windlass 210 is connected to the connecting head 110 close to the adjustment platform 200 and the right-side anchor windlass 210 is connected to the connecting head 110 far from the adjustment platform 200, the two anchor windlasss 210 simultaneously tighten the corresponding pulling members 220 to control the rotation of the suction anchor 100 in a second direction, which is opposite to the first direction. When the azimuth angle of the suction anchor 100 needs to be adjusted in two opposite rotation directions, the related operator needs to dive into the water and change the connection position of the traction member 220 and the connection head 110, so as to realize the reverse control of the adjustment of the rotation direction of the suction anchor 100.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the invention. This need not be, nor should it be exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
