Description

Technical Field

[0001] The utility model relates to a suction cylinder structure for construction of a floating offshore wind power floating body foundation, belonging to the technical field of offshore wind power construction. Background Art

[0002] The tower of offshore wind power generation needs to be supported on the jacket foundation through a floating foundation, in order to ensure the stable adsorption of the floating foundation and the jacket foundation.

[0003] In the existing offshore wind power technology (see Chinese Patent Publication No. CN118148175A), although it is disclosed that negative pressure is generated inside the suction cylinder for adsorption, since the floating foundation and the suction cylinder are both made of metal materials, they corrode in seawater, and the top edge of the suction cylinder and the bottom surface of the floating foundation become uneven and cannot be in close contact. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a suction cylinder structure for the construction of a floating offshore wind power floating body foundation.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a suction cylinder structure for construction of a floating offshore wind power buoy foundation, comprising:

[0007] The bottom plate is sealed and fixedly connected with the wall plate around the bottom plate, and the wall plate and the bottom plate form a downwardly concave cylindrical structure;

[0008] The wall panel has a rubber structure layer composed of elastic rubber;

[0009] The wall panel is sealed and fixedly connected with a connecting pipe, a pressure control valve is sealed and installed on the connecting pipe, and the pressure control valve is connected with a water pump.

[0010] A circular supporting tube is sealed and fixed on the top of the wall panel, and a rubber structure layer is wrapped around the outside of the supporting tube.

[0011] The top surface of the rubber structure layer is a plane.

[0012] It also includes a jacket with its bottom inserted into the seabed, and a bottom plate fixed on the jacket.

[0013] The wall plate and the bottom plate are both in arc shape.

[0014] An annular rib is provided inside the wall panel, and a reinforcement ring is fixedly connected to the annular rib.

[0015] The beneficial effects of the present invention are as follows: the rubber structural layer on the bottom surface of the floating body foundation and the top of the wall panel are elastically deformed and in close contact, and the elastic deformation of the rubber structural layer supplements the concave and convex joints on the top of the wall panel and the bottom surface of the floating body foundation corroded by sea water, thereby solving the problem of corrosion in sea water, which causes the top edge of the suction tube and the bottom surface of the floating body foundation to become concave and convex and cannot be in close contact.

[0019] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0020] like Figures 1 to 2 shown.

[0021] The present application discloses a suction cylinder structure for construction of a floating offshore wind power buoy foundation, comprising:

[0022] The bottom plate 15 is fixed on the top of the pipe frame 2, and the periphery of the bottom plate 15 is sealed and fixedly connected to the wall plate 14, and the wall plate 14 and the bottom plate 15 are both in an arc shape. The wall plate 14 and the bottom plate 15 form a downwardly concave cylindrical structure.

[0023] A circular supporting tube 18 is sealed and fixed on the top of the wall panel 14 . The outside of the supporting tube 18 is wrapped with a rubber structure layer 19 made of elastic rubber. The top surface of the rubber structure layer 19 is flat.

[0024] The wall panel 14 has an annular rib 16 inside, to which a reinforcement ring 17 is fixedly connected. The reinforcement ring 17 reinforces the wall panel 14 when it is pre-deformed by inward extrusion. The annular rib 16 and reinforcement ring 17 are located below the rubber structure layer 19. When the rubber structure layer 19 is elastically deformed by contact and compression with the floating foundation 3, the annular rib 16 and reinforcement ring 17 can be received by the annular rib 16 and reinforcement ring 17.

[0025] The wall plate 14 is tightly and fixedly connected to a connecting pipe 12, on which a pressure control valve 13 is tightly mounted. The pressure control valve 13 is connected to a water pump 11, which is placed on a hoisting platform and is not underwater. The bottom of the jacket 2 is inserted into the seabed.

[0026] After the floating foundation 3 corresponds to the top of the wall panel 14, water is injected into the floating foundation 3 to make it descend until the bottom surface of the floating foundation 3 is elastically deformed and in close contact with the rubber structural layer 19 on the top of the wall panel 14. The elastic deformation of the rubber structural layer 19 supplements the concave and convex joints between the top of the wall panel 14 and the bottom surface of the floating foundation 3 corroded by seawater, solving the problem of corrosion in seawater, which causes the top edge of the suction tube and the bottom surface of the floating foundation to become concave and convex and cannot be in close contact.

[0027] The water inside the cylindrical structure formed by the wall panel 14 and the bottom plate 15 is then pumped out by the water pump 11, and negative pressure is generated inside the wall panel 14. The bottom surface of the floating foundation 3 is more tightly adsorbed on the top edge of the wall panel 14. When negative pressure is generated inside the wall panel 14, the rubber structure layer 19 outside the top edge of the wall panel 14 is accumulated inside the top edge of the wall panel 14 under the action of the negative pressure, further ensuring the tightness of the contact between the bottom surface of the floating foundation 3 and the top of the wall panel 14.

[0028] The present application provides a method for constructing a suction cylinder structure for use in construction of a floating offshore wind turbine foundation, comprising:

[0029] Water is injected into the floating foundation 3 corresponding to the top of the wall panel 14 of the suction cylinder structure used for the construction of the floating offshore wind power floating foundation, so that the bottom surface of the floating foundation 3 and the rubber structural layer 19 on the top of the wall panel 14 are elastically deformed and closely contacted. The water pump 11 draws out the water inside the wall panel 14 through the connecting pipe 12 and the pressure control valve 13, and a negative pressure is generated inside the wall panel 14. The rubber structural layer 19 outside the top edge of the wall panel 14 accumulates inside the top edge of the wall panel 14, ensuring the tightness of the contact between the bottom surface of the floating foundation 3 and the top of the wall panel 14.
