Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 4 shown, an embodiment of the present invention discloses a floating body connection device for connecting a first floating body 500 to be connected and a second floating body 600 to be connected. The floating body connection device includes a first buffer module 100, a second buffer module 200, a rotating connecting arm 300, and a quick disassembly and assembly component 400.

[0031] Among them, the first buffer module 100 includes a first connecting plate 101, a first buffer mounting plate 102, and a first buffer member 103. The first connecting plate 101 is used to connect with the first floating body 500 to be connected.

Both ends of the first buffer member 103 are respectively connected to the first connecting plate 101 and the first buffer mounting plate 102. The second buffer module 200 includes a second connecting plate 201, a second buffer mounting plate 202, and a second buffer member 203. The second connecting plate 201 is arranged on the side of the first buffer mounting plate 102 away from the first connecting plate 101. The second buffer mounting plate 202 is arranged between the second connecting plate 201 and the first buffer mounting plate 102. Both ends of the second buffer member 203 are respectively connected to the second connecting plate 201 and the second buffer mounting plate 202. The first end of the rotating connecting arm 300 is rotatably connected to the first buffer mounting plate 102, and the second end of the rotating connecting arm 300 is rotatably connected to the second buffer mounting plate 202. The quick disassembly and assembly component 400 includes a first disassembly and assembly fitting 401, a second disassembly and assembly fitting 402, and a pin 403. The first disassembly and assembly fitting 401 is connected to the side of the second connecting plate 201 away from the second buffer member 203. The second disassembly and assembly fitting 402 is connected to the second floating body 600 to be connected. One of the first disassembly and assembly fitting 401 and the second disassembly and assembly fitting 402 is provided with a convex portion 4011, and the other is provided with a concave portion 4021 that cooperates with the convex portion 4011. The convex portion 4011 is provided with a first jack, and the concave portion 4021 is provided with a second jack coaxial with the first jack. The pin 403 can penetrate through the first jack and the second jack, and the included angle between the axis of the first jack and the vertical direction is greater than or equal to 0° and less than 90°.

[0032] When using the floating body connection device provided by the present invention, the first connecting plate 101 of the first buffer module 100 is pre-connected to the first floating body to be connected 500, the second disassembly and assembly fitting 402 in the quick disassembly and assembly component 400 is connected to the second floating body to be connected 600, and the first disassembly and assembly fitting 401 in the quick disassembly and assembly component 400 is connected to the second connecting plate 201 in the second buffer module 200. When connecting two floating bodies to be connected at sea, only the convex part 4011 and the concave part 4021 need to be fitted and connected, and the pin 403 is inserted through the first insertion hole of the convex part 4011 and the second insertion hole of the concave part 4021. Since the first insertion hole and the second insertion hole are coaxial, and the included angle between the axis of the first insertion hole and the vertical direction is greater than or equal to 0° and less than 90°, that is, the pin 403 is placed vertically or inclined at an acute angle to the vertical direction. Therefore, the pin 403 can be stably installed in the first insertion hole and the second insertion hole by the action of its own gravity, and the stable connection between the first disassembly and assembly fitting 401 and the second disassembly and assembly fitting 402 can be realized without installing fasteners on the pin 403, further reducing the installation steps, reducing the replacement difficulty, and improving the replacement efficiency; after quickly connecting the second floating body to be connected 600 to the floating body connection device through the quick disassembly and assembly component 400, the connection between the first floating body to be connected 500 and the second floating body to be connected 600 is realized. When encountering multi-directional wind and wave sea conditions, relative linear displacement or relative rotational displacement occurs between adjacent floating bodies. The floating body connection device realizes tensile and compressive deformation and torsional deformation through the first buffer member 103 of the first buffer module 100, the second buffer member 203 of the second buffer module 200, and the rotating connection arm 300 that rotatably connects the first buffer mounting plate 102 and the second buffer mounting plate 202, playing a buffering role, reducing the load on the floating body connection device, reducing the ultimate failure phenomenon and fatigue failure phenomenon suffered by the floating body connection device, and prolonging the service life of the floating body connection device. Thus, it can be seen that the floating body connection device provided by the present invention not only realizes quick disassembly and assembly, improves the replacement efficiency, but also can deform correspondingly when bearing a load, playing a buffering role, thereby reducing the damage of the floating body connection device and prolonging the service life.

[0034] Further, the telescopic directions of the multiple first hydraulic telescopic rods can be set in parallel or not in parallel. Any setting method that can meet the usage requirements falls within the protection scope of the present invention. Similarly, the telescopic directions of the second hydraulic telescopic rods can be set in parallel or not in parallel. Any setting method that can meet the usage requirements falls within the protection scope of the present invention.

The angle between the telescopic directions of any two second hydraulic telescopic rods is greater than 0° and less than 90°, that is, the angles between the telescopic directions of each second hydraulic telescopic rod are all acute angles. In this way, multi-directional buffering is realized through the multiple first hydraulic telescopic rods and the multiple second hydraulic telescopic rods, the buffering performance of the floating body connection device is improved, and the occurrence of extreme damage and fatigue damage is further reduced, and the service life is extended.

[0035] In addition, the two ends of the first hydraulic telescopic rod are respectively rotatably connected to the first connecting plate 101 and the first buffer mounting plate 102, and the two ends of the second hydraulic telescopic rod are respectively rotatably connected to the second connecting plate 201 and the second buffer mounting plate 202, so as to release the degrees of freedom at both ends of the first hydraulic telescopic rod and the degrees of freedom at both ends of the second hydraulic telescopic rod, and further improve the flexibility and deformation ability of the floating body connection device.

[0036] It should be understood that the two ends of the first hydraulic telescopic rod and the first connecting plate 101 and the first buffer mounting plate 102, as well as the two ends of the second hydraulic telescopic rod and the second connecting plate 201 and the second buffer mounting plate 202 can all be rotatably connected by means of a universal joint, a universal bearing or a ball hinge, etc. Any connection method that can meet the requirements of rotational connection falls within the protection scope of the present invention.

[0038] The axis of the first jack provided by the present invention can be set vertically or obliquely at an acute angle to the vertical direction. As long as the setting method can meet the use requirements, it belongs to the protection scope of the present invention.

Then, through the cooperation of the limiting boss and the limiting groove and the action of the pin 403, the relative rotation of the first dismountable and mountable fitting 401 and the second dismountable and mountable fitting 402 is restricted, so as to realize the positioning function of the first dismountable and mountable fitting 401 and the second dismountable and mountable fitting 402 during offshore construction, ensure that the first dismountable and mountable fitting 401 and the second dismountable and mountable fitting 402 are installed in place, and improve the connection stability of the floating body connection device.
