Background
Mooring chains are important equipment for mooring and positioning of offshore floats, wherein steel chains are indispensable components in mooring systems due to excellent bearing capacity, fatigue resistance and wear resistance. Mooring chains on a drilling platform are typically connected to the platform by anchors and chain stoppers, with some platforms connected to the mooring chains by chain stoppers or tensioners. In addition, some platforms are directly connected with a mooring chain in order to save space and cost, and the length of a chain link cannot be adjusted at the moment, so that inconvenience is brought to the whole mooring leg tightening. Shackles are a common type of chain connecting assembly commonly used to connect chain links and other assemblies. In order to improve fatigue performance, the traditional terminal shackle usually adopts an elliptical pin, and is large in opening gear, so that other parts can be conveniently connected. However, when the structure is used for connecting a chain, because the cross section of the transverse pin is not circular, the chain joint cannot rotate, and extra torque is generated on the shackle, so that the use performance of the chain joint is influenced.

In a preferred embodiment, one of the sets of first shackles of the mooring chain assembly at the end is connected to a second shackles.
In the preferred scheme, the device also comprises a third shackle, the third shackle and the second shackle are vertically arranged, and a transverse pin of the second shackle is arranged in a shackle body of the third shackle.
In a preferable scheme, the diameter of the round pin of the first shackle is 1.5-1.8 times of the diameter of the chain ring of the mooring chain.
According to the tool for measuring the elongation of the offshore wind power floating body mooring cable, the length of the whole mooring chain is adjusted by adjusting the number of the mooring chain assemblies, the mooring chain assemblies are connected through the first shackle, the installation is rapid, meanwhile, a chain ring connected with the first shackle is convenient to rotate, the torque is eliminated, the connection strength is improved, meanwhile, in the using process, due to the matching of the lug boss and the rotation stopping plane, the round pin is prevented from rotating to cause the falling of the round pin, and the connection stability is ensured.
