SHAPE-CHANGING MULTI-FUNCTIONAL VESSEL BERTHING DEVICE HAVING FIVE DEGREES OF FREEDOM

The present invention discloses a shape-changing multi-functional vessel berthing device having five degrees of freedom, comprising: a mounting base, a parallel berthing support, an elliptical chuck base, a magnetic chuck, and an electromagnetic 5 brake. During berthing, the parallel berthing support drives the elliptical chuck base and the magnetic chuck to stretch out from a hull, and the electromagnetic force generated by the magnetic chuck after being powered on connects the vessel hull to a wharf or other hulls to implement mooring; in de-berthing, the magnetic chuck is powered off, and the parallel berthing support drives the elliptical magnetic chuck to 10 recover and retract into the hull. Three telescopic cylinders in the parallel berthing support adopt a double-acting air cylinder or a double-acting hydraulic cylinder, which further has two-way pressure retaining and shock absorbing functions in addition to connection-supporting and telescopic functions. Multi-point steady mooring can be implemented by means of a multi-point arrangement, significantly 15 reducing the impact force acting on the wharf, the offshore platform, or other vessels during the berthing and ensuring the security of the berthing. The present invention further has the advantages such as a simple structure, high security, good stability, and simple and convenient operation and maintenance. 214' 2 4 2 4
