A connection device between modules of a super-large floating structure

Abstract

The invention discloses a connecting device for ultra-large type floating structure modules. The connecting device comprises two bases, two spherical hinge connecting rods, a spherical hinge support and a spring, one end of each of the two spherical hinge connecting rods is fixed on the inner surface of each base, the other ends of the spherical hinge connecting rods are connected through the spherical hinge support, an included angle between the two spherical hinge connecting rods is 180 degrees, the spring is spirally coiled on the two spherical hinge connecting rods from top to bottom, and the two ends of the spring are respectively fixed on the inner surfaces of the two bases. The connecting device for the ultra-large type floating structure modules stops and limits the relative motion between the two independent floating structure modules through a resisting tension-compression stress and a resisting flexion torsion moment produced by the device comprising the bases, the two spherical hinge connecting rods, the spherical hinge support and the spring. The device is simple in structure, is easy to maintain, and effectively limits the relative motion between the two independent floating structure modules.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a connection device between modules of a super-large floating structure. technical background [0002] Due to the huge size and different uses of ultra-large marine floating structures, from the perspective of maintenance and use, their structure must be modular, and the connection between modules is particularly important. [0003] Currently, the commonly used connection devices for super-large floating structure modules with spherical hinges mainly limit the translation between modules of super-large floating structures along three orthogonal directions, and it is difficult to limit the rotation around three orthogonal axes. [0004] Patent Publication No. CN102975822A discloses a connector and a connection method between modules of super large marine floating structures. Its connector includes at least two pairs of positive pole bodies and negative pole bodies arra...

Problems solved by technology

Although it can limit the translation along three orthogonal directions and the rotation around three orthogonal axes between two super-large floating structure modules at the same time, its connecting device is an active connecting device, which requires a hydraulic system to drive the specific connection. member

At the same time, the tensile and compressive stresses and bending and torsional moments generated by the relative movement between the two ultra-large floating structure modules are all borne by the same connecting member, which can easily cause the connecting member and its base to be overstressed, resulting in connection failure or even structural damage.
