Description

Technical Field

[0001] This utility model relates to a floating wind power nylon cable laying and wet storage installation construction structure, belonging to the field of offshore wind power construction technology. Background Technology

[0002] During the construction of underwater suction anchor mooring, using anchor chains alone causes significant disturbance to the seabed, and this process often requires substantial time and manpower. To meet the high precision and efficiency requirements of offshore wind farms for suction anchor installation, the existing mooring system needs to be readjusted, adopting a mooring system composed of anchor chains and nylon cables (see Chinese Patent Publication No. CN110626466B).

[0003] When the nylon cable is lowered to the seabed, it is necessary to prevent the nylon cable from being lost or twisted. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a floating wind power nylon cable laying and wet storage installation construction structure.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a floating wind power nylon cable laying and wet storage installation construction structure, including:

[0007] A construction structure for laying and storing nylon cables in wet conditions, with the location marked and twist prevented.

[0008] The laying and wet storage installation construction structure includes nylon cables on the seabed;

[0009] The end of the nylon cable is connected to a lifting sling B, which is connected to a steel wire. The steel wire is connected to a counterweight, which rests on the seabed under its own weight.

[0010] The nylon cable is equipped with a float via a lifting sling, and the lifting sling has an extension section after connecting to the float.

[0011] The counterweight is connected to a small buoy via steel wire B.

[0012] The small buoy with a central core floats 3 meters above the seabed mud surface.

[0013] The nylon cable has a protective sleeve on the outside to reduce friction damage.

[0014] The beneficial effects of this utility model are as follows: the weight of the counterweight itself restricts the pulling of the nylon cable through the lifting sling B and the steel wire, thereby preventing twisting; the float marks the position of the nylon cable; and the small buoy through the core marks the counterweight, preventing the nylon cable from being lost. This enables the nylon cable to be wet-stored on the seabed, meeting the needs of preventing loss and twisting of the nylon cable after it has been lowered to the seabed. Attached Figure Description

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] like Figs. 1-2 As shown.

[0020] This application discloses a floating wind power nylon cable laying and wet storage installation construction structure, comprising:

[0021] The nylon cable 2 is located on the seabed 1. The nylon cable 2 is equipped with a buoy 22 by a lifting sling 21. The lifting sling 21 has an extension after connecting to the buoy 22. The extension of the lifting sling 21 is used to connect to the ship.

[0022] The end of the nylon cable 2 connected to the lifting sling 21 is connected to the lifting sling B3. The lifting sling B3 is connected to the steel wire 31, and the steel wire 31 is connected to the counterweight 4. The counterweight 4 rests on the seabed 1 by its own weight.

[0023] The counterweight 4 is connected to a small buoy 5 via a steel wire B41. The small buoy 5 floats 3 meters above the muddy surface of the seabed 1.

[0024] During the wet storage of nylon cable 2, it may come into contact with and rub against the muddy surface of seabed 1, and may also scrape against the ship's anchor chain during subsequent reconnection work. Therefore, adding a protective sleeve to nylon cable 2 during the lowering process can reduce this frictional damage and extend its service life. It is important to note that a sleeve friction simulation experiment must be conducted before using the protective sleeve, and its use is only permitted after obtaining the owner's approval. During the lowering process, workers will secure the nylon cable with the protective sleeve.

[0025] The counterweight 4 uses its own weight to pull and restrict the nylon cable 2 through the lifting sling B3 and the steel wire 31, thus preventing twisting. The buoy 22 marks the position of the nylon cable 2, and the small buoy 5 marks the counterweight 4 to prevent the nylon cable 2 from being lost. This allows the nylon cable 2 to be wetted on the seabed 1, meeting the requirements of preventing loss and twisting of the nylon cable 2 after it has been lowered to the seabed 1.

[0026] Both steel wire B41 and steel wire 31 are galvanized or copper-plated steel wires resistant to seawater corrosion.
