[0002] With the development of offshore wind power in deep sea in China, the sea condition is more complex, the conventional self-elevating wind power installation platform has limited draft, and cannot satisfy the development of offshore installation operation in deep sea. Although the wind power installation crane ship has strong lifting capacity, the ship body movement range is large due to the influence of wind and wave, which is not conducive to the installation of offshore wind power foundation, and even if the installation is carried out, the installation efficiency is low. Therefore, there is an urgent need for a device which can be applied to different water depth conditions, has small ship body movement range during installation operation, and can satisfy the installation needs of offshore wind power foundation in deep sea.

[0042] The suction anchor lifting and adjusting assembly comprises a winch 11, a support 12 and an anchor clamping module 13; the support 12 is installed on the ship body 1; the winch 11 is installed at the bottom of the support 12; one end of the anchor cable 4 is connected with the corresponding winch 11, and the other end is connected with the corresponding suction anchor 3 after passing through the top of the corresponding support 12; the anchor clamping module 13 is arranged on one side of the corresponding support 12 and extends out of the ship body 1, which is a hydraulic clamp in particular.

[0043] The working principle of the embodiment is as follows:

[0044] The ship body 1 is first parked at the wharf, each winch 11 and the corresponding support 12 and anchor cable 4 are matched to adjust the corresponding suction anchor 3, so that the plurality of suction anchors 3 are respectively arranged on both sides of the ship body 1, and the corresponding anchor clamping module 13 is used to clamp and fix the suction anchor 3, so as to avoid the ship body 1 from shaking during sailing; then, the crane at the wharf lifts the wind power foundation 14 into the containing space 6, the mechanical arm in the containing space 6 extends towards the wind power foundation 14, and the hydraulic drive mechanical arm clamps the wind power foundation 14; the lifting module 10 is connected with the top lifting point of the wind power foundation 14 through a sling.

[0045] Before the ship body 1 leaves the wharf, ballast water is injected into the ballast tank of the ship body 1 to increase the draft of the ship body 1 and ensure the stability of the ship body 1 during transportation.

[0046] When the ship body 1 moves to the upper side of the approximate installation position of the wind power foundation 14, the anchor clamping module 13 releases the suction anchor 3, and the winch 11 releases the suction anchor 3 again; after the suction anchor 3 sinks to a certain depth below the mud surface of the seabed, the suction anchor 3 draws the seawater in its own interior through the pump valve system (self-provided) of the suction anchor, forms negative pressure, and fixes the suction anchor 3 to the seabed.
