Problems solved by technology

The suction pump of the suction anchor in the prior art has insufficient openings, which will lead to insufficient negative pressure caused by slow pumping speed during the sinking process of the suction anchor
In addition, pipeline blockage may also occur during grouting construction, which will lead to low work efficiency if there is no spare grouting port

Abstract

The invention relates to the technical field of offshore wind power, in particular to a suction anchor and a using method of the suction anchor. The pump opening or the grouting opening is designed through the adapter sleeve to improve the utilization rate of existing holes, the number of the holes in the cylinder top is reduced, the structural strength of the cylinder top is improved, and the production cost is reduced. When the adapter piece is connected with the pump port, the grouting equipment is connected with the adapter piece and the grouting port, so that the number of grouting inlets can be increased, and the situation of grouting blockage is avoided; or when the adapter piece is connected to the grouting opening, the suction pump is connected with the adapter piece and the pump opening, so that the number of drainage outlets can be increased, the drainage amount is increased, and the situation that the negative pressure is insufficient due to insufficient water pumping in the penetration process of the suction anchor is avoided. Through the arrangement, the working efficiency of the suction anchor can be improved and the production cost and the installation cost of the suction anchor can be reduced on the premise of meeting the requirements of water pumping and grouting construction.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to a suction anchor and a method for using the suction anchor. Background technique [0002] With the development of offshore wind power construction to deep water areas, floating wind turbines have begun to be applied. Floating wind turbines are mainly fixed on the sea surface by suction anchors and mooring cables. During the construction stage, the suction anchor sinks to a certain depth under the action of its own weight, which is called the initial mud depth. Relying on the initial mud penetration depth to form the initial sealing condition is an important guarantee for the suction anchor to sink smoothly. The anchoring force provided by pumping water from the inside of the anchor barrel to form an internal and external pressure difference causes the anchor barrel to sink to the design depth. After the subsidence is completed, the water pumping is stopped and the ...
