Detailed ways

The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, a large floating body module flexible connection device according to the present invention includes a fixed socket 1 and a flexible card seat, the fixed socket 1 is provided with a slot 11 on the front, and the upper port of the slot 11 runs through the fixed socket 1, the lower end of the slot 11 is closed, and the side of the fixed socket 1 is provided with a first pin 13 passing through the slot 11; The vertical shaft of the joint 21 is hinged with the rotating base 2, and the horizontal shaft of the cross universal joint 21 is hinged with a movable plug 22, which is adapted to the slot 11 and connected to the fixed socket 1 through the first pin 13; The fixed socket 1 and the rotating base 2 are respectively welded on two adjacent floating body modules. Under the connection, the adjacent floating body modules can move relative to each other but cannot be displaced relative to each other, eliminating the influence of the torque generated by the lateral and longitudinal swings of the floating body modules on the connecting device, and improving the safety and service life of the floating body modules.

The slot 11 is a dovetail slot or an inverted T slot, and the flexible plug 22 is provided with an embedded head 23 adapted to the slot 11, and the embedded head 23 also adopts a dovetail head or a T-shaped head to fit the slot 11 forms a horizontal connection, limits the displacement between two adjacent buoyant modules, avoids collisions when they sway on the water surface, and improves the safety of the buoyant modules and the service life of the connecting device.
