During docking and assembly, the hydraulic rod 14 in the hollow tube 3 on the first bracket 2 can adjust the length of the bridge mechanism 5, so as to facilitate the docking of the adapter plate 6 on the bridge mechanism 5 with other floating components. When the bridge mechanism 5 is in use, when a soft connection is required, the connecting frame 51 of the bridge mechanism 5 and the adapter plate 6 are connected by a spring 1 52 frame 53 and a spring 2 54. After the connection, it can float along the water surface. The floating plate 55 is arranged in the frame 53 and can float on the water surface to increase the buoyancy. When a hard connection is required, the hard connection component 56 is started to realize the hard connection between the adapter plate 6 and the connecting frame 51. The soft and hard connection is easy to switch, which is convenient for flexible construction according to the specific use requirements of the floating structure.

[0035] Furthermore, the floating property of the entire connection structure is adjusted by providing a floating mechanism 7 .

[0036] In the embodiments of the present invention, please refer to Figures 1 to 6The hard connection assembly 56 includes a guide sleeve 561, which is installed on the front side of the bottom end of the connecting frame 51, and a conical interface 501 is provided at the front end of the guide sleeve 561.

[0037] The conical joint 565 is plug-fitted with the conical interface 501 .

[0038] It should be noted that: when a rigid connection is required, the hydraulic rod 562 is started to contract, thereby pulling the steel cable 563 to move along the guide sleeve 561. When pulling, the conical joint 565 is simultaneously pulled close to the guide sleeve 561 until it is pulled and inserted into the conical interface 501, completing the rigid connection between the connecting rod 564 and the guide sleeve 561, thereby realizing a rigid connection.

When other connection angles need to be adjusted, the connecting block 64 and the adjustment ring 63 are driven to slide along the boss 62 by rotating the driving plate 65. After adjusting to the appropriate angle, align the pin rod 66 with the corresponding pin hole 601, and then screw the pin rod 66 into the pin hole 601.

[0042] In the embodiments of the present invention, please refer to Figures 1 to 6The floating mechanism 7 includes a support shaft 71, and two support shafts 71 are provided. The two support shafts 71 are symmetrically mounted with the outer wall of the hollow tube 3, and a fan plate 72 is rotatably mounted on the support shaft 71, and a transmission gear 73 is fixedly mounted on one end of the fan plate 72 and the support shaft 71. A folded oilcloth 74 is installed between the fan plate 72 and the hollow tube 3, and a driving member 75 for driving the transmission gear 73 to rotate is installed on the polygonal base 1;

[0043] It should be noted that when the floating mechanism 7 is in use and the buoyancy needs to be adjusted, the drive gear 73 is driven by the driving member 75 to drive the fan plate 72 to rotate around the support shaft 71, thereby adjusting the unfolding range of the folding tarpaulin 74, thereby achieving buoyancy adjustment. When the water surface impacts, the fan plate 72 and the folding tarpaulin 74 can provide buffering.

[0044] In the embodiments of the present invention, please refer to Figures 1 to 6 The driving member 75 includes a bidirectional threaded rod 751, which is rotatably installed in a T-slot 101 provided on the polygonal base 1, and a T-block 754 is symmetrically threadedly installed on the bidirectional threaded rod 751, and the T-block 754 is slidably matched with the T-slot 101, and a transmission plate 755 is hinged on the T-block 754, and the transmission plates 755 on the two T-blocks 754 are hinged with a driving block 756, and a driving rod 757 is fixedly installed on the driving block 756, and a double-toothed side plate 758 is fixedly installed on the driving rod 757, and the double-toothed side plate 758 is meshed with the transmission gear 73;

[0045] It should be noted that when the driving member 75 is in use, the two-way threaded rod 751 is rotated to adjust the two T-blocks 754 to slide relative to each other along the T-slot 101. When sliding, the double-toothed side plate 758 is driven to move through the transmission plate 755, the driving block 756 and the driving rod 757, thereby meshing with the transmission gear 73 and driving the fan plate 72 to rotate around the support shaft 71.

[0046] In the present embodiment: the driving member 75 also includes a transmission rod 752 rotatably mounted on the polygonal base 1, and a servo motor 753 for driving the transmission rod 752 to rotate. The transmission rod 752 is connected to the bidirectional threaded rod 751 via a gear transmission, so that the transmission rod 752 is driven to rotate by the servo motor 753. The transmission rod 752 is connected via a gear transmission to drive the bidirectional threaded rod 751 to rotate, thereby realizing driving. In this way, the servo motor 753 can be remotely controlled to adjust the buoyancy.

[0047] The working principle of the connection device for large marine floating structures provided by the present invention is as follows:

[0048] When in use, when building the floating structure, the polygonal base 1 is used for one-to-one extension and docking. During docking and assembly, the hydraulic rod 1 4 in the hollow tube 3 on the first bracket 2 can adjust the length of the bridge mechanism 5, so as to facilitate the docking of the adapter plate 6 on the bridge mechanism 5 with other floating components. When the bridge mechanism 5 is in use, when a soft connection is required, the connecting frame 51 of the bridge mechanism 5 and the adapter plate 6 are connected by the spring 1 52 frame 53 and the spring 2 54. After the connection, it can float along the water surface. The floating plate 55 arranged in the frame 53 can float on the water surface to increase the buoyancy; when a hard connection is required, the hydraulic rod 2 562 is started to contract, thereby pulling the steel cable 563 to move along the guide sleeve 561, and when pulling, the conical joint 565 is simultaneously pulled close to the guide sleeve 56 1, until it is pulled and inserted into the conical interface 501, the hard connection between the connecting rod 564 and the guide sleeve 561 is completed, thereby realizing the hard connection; when the buoyancy needs to be adjusted, the transmission rod 752 is driven to rotate by the servo motor 753, and the transmission rod 752 is connected through gear transmission to realize driving the two-way threaded rod 751 to rotate, and the two-way threaded rod 751 adjusts the two T-blocks 754 to slide against each other along the T-slot 101. When sliding, the double-toothed side plate 758 is driven to move through the transmission plate 755, the driving block 756 and the driving rod 757, thereby engaging with the transmission gear 73, and driving the fan plate 72 to rotate around the support shaft 71, thereby adjusting the expansion range of the folding oilcloth 74, thereby realizing buoyancy adjustment, and the fan plate 72 and the folding oilcloth 74 can be buffered when the water surface impacts;

[0049] When the adapter plate 6 is transferred, several connecting ears 61 are distributed in a circle along the axis of the adapter plate 6, and can be docked at a fixed angle through several connecting ears 61 at the bottom. When other connection angles need to be adjusted, the connecting block 64 and the adjusting ring 63 are driven to slide along the boss 62 by rotating the driving plate 65. After adjusting to the appropriate angle, align the pin rod 66 with the corresponding pin hole 601, and then screw the pin rod 66 into the pin hole 601.
