Very large floating structure module connecting device based on flexible rods

Abstract

A very large floating structure module connecting device based on flexible rods comprises two bases, two spherical hinged connecting rods, spherical hinged supports, multiple flexible rods, a plurality of connecting nuts matched with the flexible rods and a plurality of adjusting gaskets matched with the flexible rods. One ends of the two spherical hinged connecting rods are fixed to the inner surfaces of the two bases respectively, and the other ends of the two spherical hinged connecting rods are connected through the spherical hinged supports. The included angle formed between the two spherical hinged connecting rods is 180 degrees. The adjusting gaskets are placed into through holes in the bases. The two ends of the flexible rods are fixed to the two bases respectively and the flexible rods are evenly distributed on the peripheries of the bases. The device is used for connecting two independent floating structure modules, resistance tension-compressions stress and resistance bending torsion moment generated by the device composed of the bases, the spherical hinged connecting rods, the spherical hinged support, the flexible rods, the connecting nuts and the adjusting gaskets impede and limit relative motion between the two independent floating structure modules, and the device is simple in structure, easy to maintain and capable of effectively limiting relative motion between the two independent floating structure modules.

Description

technical field [0001] The invention relates to a device in the technical field of marine engineering, in particular to a connection device for super-large floating structure modules based on flexible rods. [0002] technical background [0003] 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 connectors connected between modules are particularly important. [0004] The currently used spherical hinge-type ultra-large floating structure module connection device mainly restricts the translation between the ultra-large floating structure modules along three orthogonal directions, and it is difficult to limit the rotation around the three orthogonal axes. [0005] 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 ...

Problems solved by technology

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