[0002] As a clean energy, wind power has the advantages of being low-carbon and environmentally friendly. my country has abundant offshore wind power resources. Compared with onshore wind farms, the advantages of offshore wind power are mainly that it does not occupy land resources, is basically not affected by topography, and has higher wind speeds.

[0003] After searching, the prior art has a publication number of CN218509635U that discloses a damping berthing device, including a berthing member, a pile foundation, and a plurality of dampers.

The damper is connected between the berthing member and the pile foundation, and the damper includes at least one first damping member, at least one second damping member, and a reset spring. The first damping member is connected to the berthing member, and the second damping member is connected to the pile foundation. The first damping member moves along the first direction with the berthing member and generates a damping effect due to relative friction with the second damping member. One end of the reset spring is connected to the berthing member, and the other end is connected to the pile foundation. The reset spring is used to reset the berthing member. The utility model utilizes the kinetic energy of the berthing ship to convert it into heat energy and elastic potential energy in the damping device, protects the pile foundation and reduces its impact damage by the berthing ship, and prevents the berthing ship from causing irreversible damage to the pile foundation of the offshore wind turbine.

[0004] However, although the damping mooring device of the utility model can reduce the impact damage when the hull moves and collides with the surface of the pile foundation, the pile foundation is made of steel or a relatively high-strength material as a whole. Long-term contact will scratch the surface of the hull and may seriously cause deformation of the surface of the ship. Therefore, a damping mooring device is proposed to solve the above-mentioned problems. Utility Model Content

[0010] Furthermore, a limiting assembly for limiting the connection column is disposed on the right outer wall of the connection column, and the limiting assembly includes two protruding columns threadedly connected to the right surface of the connection column and a limiting block sleeved on the outside of the connection column.

[0011] Furthermore, the plurality of convex rings are arranged vertically and equidistantly, and the rubber tube is vertically sleeved on the right side end of the connecting frame.

[0016] 1. The damping berthing device contacts the outer convex ring of the rubber tube through the surface of the hull. At the same time, the convex ring utilizes its own flexible structure to avoid collision and reduce deformation of the hull during the ship's operation.

[0017] 2. The damping mooring device, after the hull contacts the surface of the convex ring, the impact generated is transmitted to the spring along the connecting rod, and then the elastic effect of the spring is used in conjunction with the compression of the air cushion to slow down the impact force generated by the hull and the ship, thereby solving the problem that when the damping mooring device collides with the surface of the pile foundation when the ship moves, although the impact damage can be reduced, at the same time, the pile foundation is made of steel or other high-strength materials, and long-term contact will scratch the surface of the ship and may seriously cause deformation of the surface of the ship.

[0026] The damping device 8 includes two first fixed cylinders 12 fixedly connected to the right side surface of the fixing plate 1, a first buckle 13 fixedly connected to the left side of the inner wall of the first fixed cylinder 12, a spring 14 clamped on the surface of the first buckle 13, a second buckle 15 clamped on the right side of the spring 14, a connecting rod 16 fixedly connected to the right side of the second buckle 15, an air cushion 18 fixedly connected to the left side of the connecting rod 16, and a second fixed cylinder 17 fixedly connected to the right side of the first fixed cylinder 12. The deceleration device includes a first connecting plate 2 bolted to the middle of the right side of the fixing plate 1, a first connecting plate 2 fixedly connected to the right side of the first connecting plate 2 A connecting column 3 on the side, a sleeve 5 slidably mounted on the outer wall of the right side of the connecting column 3 and a second connecting plate 6 fixedly connected to the right side of the sleeve 5, a plurality of convex rings 11 are arranged vertically equidistantly, a rubber tube 10 is vertically mounted on the right side end of the connecting frame 9, the upper and lower ends of the left side of the connecting frame 9 are respectively vertically fixedly connected to the right sides of the two connecting rods 16, exhaust holes are provided on the opposite sides of the two first fixed tubes 12, a plurality of first bolt holes matching the bolts are provided on the surface of the first connecting plate 2, a plurality of second bolt holes matching the bolts are provided on the surface of the second connecting plate 6, and through holes are provided on the upper and lower sides of the sleeve 5.

[0027] Embodiment 2:

[0028] See also Figure 1-3 On the basis of embodiment 1, a limiting assembly for limiting the connecting column 3 is provided on the right outer wall of the connecting column 3, and the limiting assembly includes two protruding columns 4 threadedly connected to the right surface of the connecting column 3 and a limiting block 7 sleeved on the outside of the connecting column 3.

[0029] By adopting the above technical solution, one side of the boss 4 is threaded through the sleeve 5 and connected to the upper and lower ends of the right side of the connecting column 3 to realize the connection between the connecting column 3 and the sleeve 5. The limit block 7 is sleeved on the outside of the boss 4 to achieve limited movement.

[0030] The working principle of the above embodiment is:

[0031] The right side of the connecting column 3 is inserted into the left side of the sleeve 5, and the protruding column 4 is threadedly fixed on the surface of the connection between the connecting column 3 and the sleeve 5. The limiting block 7 is taken out and sleeved on the outer surface of the protruding column 4 for limiting connection. Then the first connecting plate 2 and the second connecting plate 6 are respectively fixed to the fixing plate 1 and the connecting frame 9 on the opposite side by bolts. When the ship is in contact with the outer surface of the rubber tube 10, it can not only effectively disperse the impact force of the ship, but also reduce the damage to the hull caused by the collision with the hull surface. The impact force generated by the hull will be transmitted to the damping device 8 and the sleeve in sequence to the left along the connecting frame 9 5, first, the sleeve 5 slides toward the outside of the connecting column 3 to shorten the overall length and reduce part of the impact force. The connecting column 3 uses the convex column 4 and the limit block 7 to slide into the sleeve 5. Then, the impact force received by the connecting rod 16 is first compressed by the spring 14 itself and drives the air cushion 18 to be compressed. The gas stored in the air cushion 18 is discharged from the air hole opened in the first fixed tube 12 to cooperate with the spring 14 to reduce the impact force. When the hull and the surface of the convex ring 11 are away from each other, the spring 14 rebounds and pushes the connecting rod 16 to support the air cushion 18 again, and the outside gas enters the air cushion 18 from the exhaust hole again.
