In recent years, China carries out a large number of artificial islands in south China sea, and builds a series of coastal projects such as ports, maritime airports and the like. Due to the complex sea conditions and the poor wave conditions in the south sea, the rough waves not only cause great obstruction to the construction of marine works, but also cause great damage to the already completed coastal works. Based on the purpose of protecting coastal facilities and natural resources, marine scientists in China are researching floating breakwaters to protect coastal projects. The floating breakwater is formed by connecting a plurality of floating breakwater modules together through a connecting device, and each two floating breakwater modules have six degrees of freedom of relative motion. Therefore, the connection device of the floating breakwater needs to overcome the motion load with full freedom, and on the basis, the convenience of sea surface installation is realized, which is a great challenge in the complex sea wave environment.

Hinged, generally refers to a connection made with a hinge. The hinge is the most important part of the hinge. The hinge may be constructed of foldable material or may be constructed of movable components. In order to make people enjoy better, hydraulic hinges and universal hinges appear, the novel hinging devices can be connected better, and the novel hinging devices also have the additional effects of vibration reduction, noise reduction and the like. Hinges have been used successfully to date on large equipment such as articulated buses, articulated trolleybuses and articulated trucks.
