Floating wind power non-tensioner anchor chain assembly structure

Abstract

This application discloses a floating wind turbine anchor chain assembly structure without tensioner, comprising: a first bottom chain made of steel chain; a nylon cable made of nylon rope connected to the first bottom chain; a top anchor chain made of steel chain connected to the nylon cable; and a mid-water buoy installed between the first bottom chain and the nylon cable to provide buoyancy. The first bottom chain, nylon cable, and top anchor chain constitute an anchor chain assembly connecting the suction anchor and the floating wind turbine foundation. Since no tensioner is installed on the anchor chain assembly, and a mid-water buoy is installed between the first bottom chain and the nylon cable to improve buoyancy, the mid-water buoy offsets part of the overall downward weight of the anchor chain, solving the problem that anchor chains with tensioners are prone to snagging and tangling with seaweed and other debris in the seawater, increasing the overall downward weight of the anchor chain in the seawater.

Description

Technical Field

[0001] This utility model relates to a floating wind turbine anchor chain assembly structure without tensioner, belonging to the field of marine wind anchor chain technology. Background Technology

[0002] The suction anchor of a floating offshore wind power mooring system needs to be connected to the floating wind power foundation via an anchor chain. The existing technology can be found in Chinese Patent Publication No. CN102277878B.

[0003] To achieve tension on the anchor chain, a tensioner is usually installed on the anchor chain (see Chinese Patent Publication No. CN220010030U). However, in actual construction environments, anchor chains with tensioners are prone to getting caught and tangled with seaweed and other debris in the seawater, increasing the overall weight of the anchor chain as it sags in the seawater. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a floating wind power tensioner-free anchor chain assembly structure.

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

[0006] This utility model provides a floating wind turbine tensioner-free anchor chain assembly structure, comprising:

[0007] The first bottom chain is made of steel chains;

[0008] The first bottom chain is connected to a nylon cable made of nylon rope;

[0009] The nylon cable is connected to a top anchor chain made of steel chain;

[0010] A mid-water buoy is installed between the first bottom chain and the nylon cable to provide buoyancy.

[0011] One end of the first bottom chain is connected to a suction anchor via an anchor shackle.

[0012] The nylon cable is provided with a nylon ferrule, and the other end of the first bottom chain is provided with an H-shaped shackle, which is engaged with the nylon ferrule.

[0013] The H-shaped shackle is connected to a connecting chain made of steel cables, and a mid-water float is connected to the top of the connecting chain.

[0014] Both ends of the connecting chain are connected to float shackles to be fastened to the medium-water floats and H-type shackles.

[0015] The top anchor chain is connected to an end shackle and a buoy shackle. The end shackle is used to connect to the floating wind turbine foundation, and the buoy shackle is used to connect to the buoy.

[0016] The end of the nylon cable away from the first bottom chain is also provided with a nylon ferrule, and the end of the top anchor chain has a cable shackle, which is fastened to the nylon ferrule.

[0017] The beneficial effects of this utility model are as follows: the first bottom chain, nylon cable, and top anchor chain constitute an anchor chain assembly connecting the suction anchor and the floating wind turbine foundation. Since no tensioner is installed on the anchor chain assembly, and a mid-water buoy is installed between the first bottom chain and the nylon cable to improve buoyancy, the mid-water buoy offsets part of the overall downward weight of the anchor chain, thus solving the problem that anchor chains with tensioners are prone to getting tangled with seaweed and other debris in the seawater, increasing the overall downward weight of the anchor chain in the seawater.

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0021] like Figure 1 As shown.

[0022] This application discloses a floating wind turbine tensioner-less anchor chain assembly structure, comprising:

[0023] The first bottom chain 3 is made of steel chain. One end of the first bottom chain 3 is connected to a suction anchor 1 through an anchor shackle 2. The suction anchor 1 is fixed in the seabed by drawing out the internal seawater to form a negative pressure.

[0024] The first bottom chain 3 is connected to a nylon cable 14 made of nylon rope. The nylon cable 14 is provided with a nylon collar 12. The other end of the first bottom chain 3 is provided with an H-shaped shackle 8, which is fastened to the nylon collar 12.

[0025] The H-shaped shackle 8 is connected to a connecting chain 10 made of steel cable. The top of the connecting chain 10 is connected to a mid-water buoy 11, which floats in the seawater and forms a marker to facilitate the retrieval and reconnection of the first bottom chain 3. Both ends of the connecting chain 10 are connected to buoy shackles 9 to be fastened and connected to the mid-water buoy 11 and the H-shaped shackle 8.

[0026] The nylon cable 14 is connected to a top anchor chain 17 made of steel chain. The top anchor chain 17 is connected to an end shackle 18 and a buoy shackle 19. The end shackle 18 is later connected to the floating wind power foundation, and the buoy shackle 19 is later connected to the buoy.

[0027] The end of the nylon cable 14, which is away from the first bottom chain 3, is also provided with a nylon collar 12, and the end of the top anchor chain 17 is provided with a cable shackle 16, which is fastened to the nylon collar 12.

[0028] The first bottom chain 3, nylon cable 14, and top anchor chain 17 constitute the anchor chain assembly connecting the suction anchor 1 and the floating wind turbine foundation. Since no tensioner is installed on the anchor chain assembly, and a mid-water buoy 11 is installed between the first bottom chain 3 and nylon cable 14 to provide buoyancy, the mid-water buoy 11 offsets part of the overall downward weight of the anchor chain, thus solving the problem that anchor chains with tensioners are prone to getting tangled with seaweed and other debris in the seawater, increasing the overall downward weight of the anchor chain in the seawater.
