Description

Technical Field

[0001] The invention relates to a construction method of a suction cylinder for construction of a floating offshore wind power buoy 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 number CN118148175A), although it is disclosed that negative pressure is generated inside the suction cylinder for adsorption, since the floating body 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 body foundation have unevenness and cannot be in close contact. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a construction method of a suction cylinder for construction of a floating offshore wind power buoy foundation.

[0005] The present invention is achieved through the following technical solutions.

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

[0007] Water is injected into the floating body foundation corresponding to the top of the wall panel of the suction tube structure used for the construction of the floating offshore wind power floating body foundation, so that the bottom surface of the floating body foundation and the rubber structure layer on the top of the wall panel are elastically deformed and closely contacted, and a water pump draws out the water inside the wall panel through a connecting pipe and a pressure control valve, generating negative pressure inside the wall panel, and the rubber structure layer outside the top edge of the wall panel is tightly piled up inside the top edge of the wall panel.

[0008] The suction cylinder structure for construction of floating offshore wind power buoy foundation comprises:

[0009] The bottom plate is sealed and fixedly connected with the wall plate at its periphery, and the wall plate and the bottom plate form a downwardly concave tube structure;

[0010] The wall panel has a rubber structure layer made of elastic rubber;

[0011] 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.

[0012] A circular supporting round tube is sealed and fixed on the top of the wall panel, and a rubber structural layer is wrapped outside the supporting round tube.

[0013] It also includes a conductor frame with a bottom inserted into the seabed, and a bottom plate is fixed on the conductor frame.

[0014] The wall plate is provided with an annular rib plate inside, and a reinforcement ring is fixedly connected to the annular rib plate.

[0015] The beneficial effects of the present invention are as follows: the rubber structural layer of 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 of 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 description.

[0020] like Figure 1 to Figure 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 used to be fixed on the top of the pipe frame 2, and the periphery of the bottom plate 15 is sealed and fixedly connected with the wall plate 14, and the wall plate 14 and the bottom plate 15 are both in arc shape. The wall plate 14 and the bottom plate 15 form a downwardly concave cylinder structure.

[0023] A circular supporting tube 18 is sealed and fixed on the top of the wall plate 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 a plane.

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

[0025] The wall plate 14 is sealed and fixedly connected with a connecting pipe 12, and a pressure control valve 13 is sealed and installed on the connecting pipe 12. The pressure control valve 13 is connected with a water pump 11, and the water pump 11 is placed on the lifting 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 closely contacted with the rubber structure layer 19 on the top of the wall panel 14. The elastic deformation of the rubber structure 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 sea water, solving the problem of corrosion in sea water, resulting in concave and convex joints on the top edge of the suction tube and the bottom surface of the floating foundation, which 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 to 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 invention provides a method for constructing a suction cylinder structure for construction of a floating offshore wind power buoy foundation, comprising:

[0029] Water is injected into the floating foundation 3 to correspond to the top of the wall panel 14 of the suction tube 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 structure layer 19 on the top of the wall panel 14 are elastically deformed and closely contacted, and 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 negative pressure is generated inside the wall panel 14. The rubber structure 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.
