Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Embodiment one

[0023] Please refer to Figures 1-5 The utility model provides a nested type multiple damping fender, including fender 1, the first cavity 2 and the second cavity 3 are sequentially seted from inside to outside in one end of fender 1, the inner chamber of first cavity 2 is provided with first damping assembly, the inner chamber of second cavity 3 is provided with second damping assembly, first damping assembly includes first limit seat 4, first damping part 5 and first bolt 6, the inner chamber of first cavity 2 is provided with first limit seat 4, a plurality of groups of first damping part 5 are limitingly connected with one side of first limit seat 4 through sliding, and the both ends of first limit seat 4 can be fastened through first bolt 6, and one side of each group of first damping part 5 is integrally formed with sliding block 7, sliding block 7 is dovetail structure part, and sliding block 7 is slidably installed on one side of first limit seat 4.

[0024] A plurality of first damping members 5 are connected to one side of the first limiting seat 4 through the dovetail-shaped sliding blocks 7 integrally formed on one side of the first damping members 5. The dovetail-shaped structure not only ensures stable sliding between the sliding blocks 7 and the first limiting seat 4, but also facilitates quick installation and disassembly. When all the first damping members 5 are correctly installed, the two ends of the first limiting seat 4 can be fastened by the first bolts 6 to lock the positions of the first damping members 5, which facilitates disassembly, realizes quick disassembly, and improves disassembly efficiency compared with the prior art.

[0025] When the fender 1 is subjected to external impact force, the impact force first acts on the second damping assembly in the inner cavity of the second cavity 3, and then acts on the first damping assembly in the first cavity 2. The first damping member 5 absorbs part of the impact force by utilizing its own elastic deformation capacity, thereby reducing the damage to the ship body and the wharf.

[0026] Specifically, the second damping assembly includes an air bag 8, a feeding pipe 9, a valve 10, and a second damping member 11. The inner cavity of the second cavity 3 is provided with the air bag 8, the inner cavity of the air bag 8 is provided with the feeding pipe 9, the two ends of the feeding pipe 9 penetrate the air bag 8 and are each connected to a group of valves 10, the two groups of valves 10 are each connected to a group of second damping members 11, the other ends of the two groups of second damping members 11 penetrate the fender 1 and are each movably connected to a group of first bolts 6, and the position of the fender 1 between the first cavity 2 and the second cavity 3 is provided with a through hole 12 corresponding to the second damping member 11.

[0027] The part of the feeding pipe 9 inside the air bag 8 is provided with an outlet for transporting the non-Newtonian fluid from the valve 10 to the feeding pipe 9, and then into the air bag 8. Before use, the air bag 8 is filled with an appropriate amount of non-Newtonian fluid through the feeding pipe 9. The non-Newtonian fluid has the characteristic that its viscosity changes when subjected to shear force, thereby exhibiting the characteristics of a solid or a liquid. This characteristic enables the non-Newtonian fluid to absorb and disperse energy when subjected to impact force,

[0028] When the fender 1 is subjected to external impact force, the impact force first acts on the air bag 8, the non-Newtonian fluid in the air bag 8 is extruded, its viscosity changes, and it begins to exhibit solid-like properties, thereby absorbing part of the impact force. Since the connecting pipe 9 is integrally connected with the valve 10, the impact force can be transmitted to the second damping member 11. The second damping member 11 further absorbs and disperses the impact force by using its own elastic deformation capability, and at the same time, the impact force also acts on the first damping member 5, thereby achieving multiple damping. The impact force does not affect the operation of the second damping member 11 due to the through hole 12. When the impact force disappears, the non-Newtonian fluid gradually returns to the original state, and the air bag 8 and the second damping member 11 also return to the original state. The recovery capability ensures that the fender 1 can maintain good damping effect after being subjected to impact force for many times. The other end of the two groups of second damping members 11 penetrates the fender 1 and is movably connected with the two groups of first bolts 6, which does not affect the rotation of the first bolts 6.

[0029] The second limiting seat 13 is embedded in the side of the fender 1 close to the first cavity 2, and can be threadedly connected with the first bolt 6. The fender 1 can be fastened by the second bolt 14. Three groups of second bolts 14 are arranged on each side of the fender 1, and the second bolts 14 can penetrate the fender 1 and the second limiting seat 13 and be threadedly connected with the ship body.

[0030] The first limiting seat 4 can be fixed by threadedly connecting the first bolt 6 penetrating the fender 1 body and the second limiting seat 13, thereby fixing the first damping member 5 and also fixing the second damping member 11. The fender 1 is fixed on the ship body by threadedly connecting the second bolt 14 penetrating the fender 1 and the second limiting seat 13 with the ship body. The fastening effect of the second bolt 14 is enhanced due to the presence of the second limiting seat 13, thereby improving the overall stability of the fender 1.

[0031] Working principle: A plurality of first damping members 5 are movably connected on one side of the first limiting seat 4 through the dovetail-shaped sliding blocks 7 integrally formed on one side of the first damping members 5. The dovetail-shaped structure not only ensures the stable sliding between the sliding blocks 7 and the first limiting seat 4, but also facilitates quick installation and disassembly. After all the first damping members 5 are correctly installed, the first limiting seat 4 can be fixed by threadedly connecting the first bolt 6 penetrating the fender 1 body and the second limiting seat 13, thereby locking the position of the first damping member 5 and also completing the installation of the second damping member 11. When the fender 1 is subjected to external impact force, the impact force first acts on the air bag 8, the non-Newtonian fluid in the air bag 8 is extruded, its viscosity changes, and it begins to exhibit solid-like properties, thereby absorbing part of the impact force. Since the connecting pipe 9 is integrally connected with the valve 10, the impact force can be transmitted to the second damping member 11. The second damping member 11 further absorbs and disperses the impact force by using its own elastic deformation capability, and at the same time, the impact force also acts on the first damping member 5, thereby achieving multiple damping.

[0032] What is not described in detail in the present description is the prior art known to the person skilled in the art.

[0033] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
