[0024] As Figures 1 - 5 As shown, an embodiment of the present invention provides a fender structure, including: a rubber fender 1, which is a hollow cylindrical shape, and one end of the rubber fender 1 is connected to the side wall 2 of the dock; a protection plate 3, which is vertically arranged at the other end of the rubber fender 1, and a rubber layer 4 is provided on the side of the protection plate 3 away from the rubber fender 1; a guide post 5, one end of which is horizontally slidably connected to the protection plate 3, and the other end extends into the rubber fender 1 and is elastically connected to its closed end; two pairs of chains 6, which are symmetrically arranged on both sides of the rubber fender 1. Each pair of chains 6 includes a first chain and a second chain. One ends of the first chain and the second chain are both connected to the embedded parts arranged on the side wall 2 of the dock, and the other ends are respectively connected to the upper and lower parts of the side of the protection plate 3 close to the rubber fender 1.

[0025] In the above embodiment, the fender structure includes a rubber fender, a protective plate, guide columns and two pairs of chains. The rubber fender is in the shape of a hollow cylinder (drum-shaped), having an open end and a closed end. The closed end is connected to the side wall of the dock and fixed on the side wall of the dock. The protective plate is vertically arranged at the open end of the rubber fender and is perpendicular to the axial direction of the rubber fender. A rubber layer is provided on the side of the protective plate away from the rubber fender, and the rubber layer can provide initial buffering and protect the ship's side. The guide columns are arranged along the axial direction of the rubber fender. One end of the guide column is horizontally slidably connected to the protective plate, and the other end extends into the rubber fender and is elastically connected to its closed end. The elastic connection method includes but is not limited to connection through a spring or a spring piece, preferably a spring, for the convenience of subsequent component installation and layout. The protective plate is horizontally slidably connected to the guide column, so that when the ship contacts the protective plate, the protective plate can slide horizontally, converting part of the ship's collision energy into momentum in the horizontal direction and reducing the impact of the ship on the protective plate. The other end of the guide column is elastically connected to the closed end of the rubber fender. When the ship contacts the protective plate, the collision force is transmitted to the spring through the protective plate and the guide column, causing the spring to compress and deform, absorbing part of the collision energy and further playing a buffering role. The two pairs of chains are symmetrically arranged on both sides of the rubber fender. Each pair of chains includes a first chain and a second chain. The first chain is horizontally arranged, and the second chain is arranged obliquely below the first chain. One ends of the first chain and the second chain are both connected to embedded parts, such as embedded hooks, provided on the side wall of the dock, and the other ends are respectively connected to hanging ears fixed on the upper and lower parts of the side of the protective plate close to the rubber fender, so as to realize the soft connection between the protective plate and the side wall of the dock, improving the connection stability between the protective plate and the rubber fender without affecting the normal displacement of the protective plate.

[0026] In the present invention, by arranging guide columns between the rubber fender and the protective plate, and horizontally slidably connecting one end of the guide column to the protective plate, and the other end extending into the rubber fender and elastically connecting, when the ship collides with the protective plate, first, the protective plate can move horizontally, converting part of the ship's collision energy into momentum in the horizontal direction and reducing the impact of the ship on the protective plate. Second, the protective plate and the guide column can expand and contract along the axial direction of the guide column, transmitting the received collision force to the elastic member, causing the spring to compress and deform, absorbing part of the collision energy. Finally, the protective plate contacts the rubber fender, transmitting the already weakened collision force to the rubber fender, and absorbing the collision energy through the deformation of the rubber fender to achieve the buffering purpose. Compared with directly absorbing energy through the deformation of the rubber fender, the present invention can effectively reduce the maximum deformation amount during the energy absorption process of the rubber fender, protect the rubber fender, extend the service life of the rubber fender, and has good use stability.

[0027] In another embodiment, such as Figure 2 、 Figure 5As shown, the rubber fender 1 includes a plastic part 7 and an elastic part 8. One end of the plastic part 7 is connected to the side wall 2 of the dock, and the other end is detachably connected to the elastic part 8. The other end of the guide post 5 extends into the plastic part 7 and is in sealed sliding connection with its inner wall. The plastic part and the elastic part of the rubber fender are provided separately and detachably connected, so that after the elastic part is fatigued and damaged, the elastic part can be replaced, which is convenient for maintaining the fender structure.

[0028] In another embodiment, as Figure 2 , Figure 4 shown, a plurality of card slots 9 are provided at intervals along the circumferential direction of the end face of the other end of the plastic part 7. A first magnet 10 is provided at the bottom of each card slot 9. An annular clamping plate 11 is fixedly provided at one end of the elastic part 8 close to the plastic part 7. A plurality of clamping blocks 12 matching with the card slots 9 are provided at intervals along the circumferential direction of the clamping plate 11. A second magnet 13 attracted to the first magnet 10 magnetically is provided on the clamping block 12. The detachable connection between the elastic part and the plastic part is realized through the clamping blocks and the card slots. The structure is simple. During installation, the first magnet provided at the bottom of the card slot and the second magnet provided on the clamping block can also assist in positioning and locking, with high installation efficiency and stable connection.

[0029] Furthermore, in order to enhance the sealing stability after the clamping block 12 is connected to the card slot 9, a rubber sealing layer 14 is provided on the side wall of the clamping block 12.

[0030] In another embodiment, as Figure 2 , Figure 4As shown, at least one card slot 9 is provided with a first through hole 15 that penetrates through the card slot 9 and the first magnet 10. At least one card block 12 is provided with a second through hole 16 that penetrates through the card block 12, the second magnet 13, and the card plate 11. The second through hole 16 corresponds to and communicates with the first through hole 15 one by one. At least one first flow channel 17 is provided inside the side wall of the plastic part 7. One end of the first flow channel 17 communicates with the inside of the plastic part 7, and the other end communicates with the first through hole 15. At least one second flow channel 18 is provided inside the side wall of the elastic part 8. One end of the second flow channel 18 is closed, and the other end communicates with the second through hole 16. Among them, a plurality of annular air bags 19 are provided at intervals along the axial direction of the inner wall of the elastic part 8. Each annular air bag 19 communicates with the second flow channel 18 through a third flow channel 20 provided inside the side wall of the elastic part 8. In the initial state, the annular air bag 19 does not contact the side wall of the guide post 5. After the ship collides with the protection plate, under the action of the collision force, the guide post moves towards the side close to the dock side wall, compressing the space inside the plastic part. The gas inside the plastic part enters the annular air bag through the first flow channel, the first through hole, the second through hole, the second flow channel, and the third flow channel, inflating the annular air bag. The inflated annular air bag wraps around the side wall of the guide post, weakening the collision force transmitted by the guide post and further playing a buffering role.

[0031] In another embodiment, as Figure 2 , Figure 5 shown, a plurality of first hydraulic rods 21 are provided at intervals along the circumferential direction inside the plastic part 7. Each first hydraulic rod 21 is arranged along the axial direction of the plastic part 7. The output end of the first hydraulic rod 21 is connected to the guide post 5, and the cylinder body end is connected to the closed end of the plastic part 7. A second hydraulic rod 22 is provided along the axial direction at the center inside the plastic part 7. The output end of the second hydraulic rod 22 is spaced from the other end face of the guide post 5 by a preset distance, and the cylinder body end is connected to the closed end of the plastic part 7. Moreover, the cylinder body ends of the plurality of first hydraulic rods 21 and the cylinder body end of the second hydraulic rod 22 are connected through a pipeline 23. After the ship collides with the protection plate, under the action of the collision force, the guide post moves towards the side close to the dock side wall and drives the first hydraulic rod to contract. The liquid inside the first hydraulic rod enters the second hydraulic rod through the pipeline, causing the second hydraulic rod to extend and providing a reverse acting force to the guide post to further weaken the collision force.

[0032] In another embodiment, as Figure 2 , Figure 5As shown, one end of the guide post 5 is fixedly provided with a connecting plate 24. The upper and lower ends of the connecting plate 24 protrude from the guide post 5. On the side of the connecting plate 24 away from the guide post 5, a plurality of connecting rollers 25 are arranged at intervals in the horizontal direction. Each connecting roller 25 is vertically arranged and rotatably connected to the connecting plate 24. On the side of the protective plate 3 close to the rubber fender 1, there is a connecting groove 26 that cooperates with the connecting plate 24. The connecting roller 25 is in contact with the connecting groove 26. The length of the connecting groove 26 in the horizontal direction is greater than the length of the connecting plate 24 in the horizontal direction. At least a pair of elastic members (not shown) are symmetrically arranged on both sides of the connecting plate 24. The elastic force direction of each elastic member is arranged in the horizontal direction, and one end of the elastic member is connected to the connecting plate 24, and the other end is connected to the connecting groove 26. The elastic member includes but is not limited to a spring or a spring sheet. By providing a connecting plate at one end of the guide post, providing connecting rollers rotatably connected thereto on the connecting plate, and placing the connecting plate and the connecting rollers in the connecting groove provided on the protective plate, the sliding connection between the guide post and the protective plate is realized. It is defined that the length of the connecting groove in the horizontal direction is greater than the length of the connecting plate in the horizontal direction, and at least a pair of elastic members are symmetrically arranged on both sides of the connecting plate, so that after the protective plate is horizontally displaced under the collision of the ship, it can be reset under the action of the elastic members, enabling the protective plate to continue to convert energy in the next collision and reducing the impact of the ship on the protective plate.

[0033] In another embodiment, as Figure 2 、 Figure 5 shown, the connecting groove 26 is a T-shaped groove, and the side wall of the lower part of the connecting groove 26 close to the guide post 5 can be telescopically moved up and down, so as to facilitate the installation of the connecting plate and the connecting rollers in the connecting groove and limit the connecting plate and the connecting rollers to prevent them from coming out.

[0034] In another embodiment, as Figure 2 、 Figure 5 shown, the protective plate 3 is a carbon fiber composite plate, and the guide post 5 is a carbon fiber composite post. The carbon fiber composite plate and the carbon fiber composite post are light in weight and high in strength, which can effectively reduce the weight of the fender structure itself, avoid drooping due to long-term suspension, and further improve the stability of the fender structure.

[0035] In another embodiment, as Figure 1 shown, one end of the rubber fender 1 is fixedly provided with a mounting plate 27. A plurality of mounting holes are arranged at intervals along the circumference of the mounting plate 27. The plurality of mounting holes correspond one by one to a plurality of embedded bolts provided on the side wall 2 of the dock and are connected by nuts. Connecting through the mounting holes on the mounting plate and the embedded bolts on the side wall of the dock is more convenient for installation.

[0036] The number of devices and the processing scale described here are used to simplify the description of the present invention. Applications, modifications, and variations of the fender structure of the present invention will be apparent to those skilled in the art.

[0037] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples described herein.
