Description

Technical Field

[0001] This utility model belongs to the technical field of buffer devices, and in particular relates to a buffer device for berthing small ships. Background Technology

[0002] Ship berthing buffers are important equipment to ensure the safe berthing of ships at docks. Due to the large weight of ships, they inevitably touch the dock during berthing, so buffers are needed to protect them.

[0003] Ships often use buffer pads for cushioning during berthing, but the cushioning performance provided by buffer pads is relatively low, and they can still cause significant impact forces on the ship during berthing. Therefore, there is a need for a small ship berthing buffer device that provides sufficient space for cushioning through buffer rods and buffer pads, reducing impact forces. At the same time, the foldable buffer pad can rotate while ensuring sufficient contact area, thereby avoiding the problem of excessive water flow resistance caused by the flat placement of the buffer pad during navigation. Utility Model Content

[0004] The purpose of this invention is to provide a buffer device for small boat docking, which has the advantages of providing sufficient space for buffering through buffer rods and buffer pads to reduce collision force, and the ability to rotate through the foldable buffer pad to ensure sufficient contact area, thereby avoiding the problem of excessive water flow resistance caused by the flat placement of the buffer pad during navigation, thus solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A buffer device for small ship berthing includes a hull, a drive box is fixedly installed inside the hull, an outer rod is installed at one end of the drive box, an inner rod is movably installed on one side of the outer rod, a connecting rod is fixedly installed at one end of the inner rod, and fixed rods are fixedly installed at both ends of the connecting rod. Buffer rods are fixedly installed on both sides of the hull, and a fixed ring is fixedly installed at one end of the buffer rod. A connecting block is fixedly installed on one side of the fixed ring. A rotating block is movably installed on one side of the buffer rod, and a buffer pad is fixedly installed on one side of the rotating block. The buffer pads are arranged in two sets, and the two sets of buffer pads are rotatably connected. A first spring is installed on one side of the outer rod, and a sleeve rod is installed on one side of the first spring. The sleeve rod and the outer rod are connected by the first spring. An arc-shaped plate is fixedly installed at one end of the first spring, and the arc-shaped plate cooperates with the buffer pad.

[0006] Preferably, one end of the sleeve rod has a sliding groove that mates with the connecting rod, and the inner rod fits snugly against the inside of the sleeve rod, and one end of the buffer rod is fixedly connected to the hull.

[0007] Preferably, a second spring is installed on one side of the fixing ring, and the buffer pad is made of rubber.

[0008] Preferably, one side of the arc-shaped plate is curved, the fixing ring and the fixing rod are fitted together, and both ends of the fixing ring are in contact with the fixing rod.

[0009] Preferably, the drive box is equipped with a pneumatic device connected to the inner rod, and the outer rod has a slot that matches the inner rod.

[0010] The beneficial effects of this utility model are:

[0011] This invention, by setting a connecting rod and a fixed rod, allows the inner rod to drive the fixed rod to move when the drive box is started, thereby pulling the fixed ring to one side. At this time, the buffer rod is subjected to tensile force and displacement, causing the rotating block to rotate, which in turn causes the buffer pad to rotate. When the buffer pad rotates, it is limited by the arc plate, causing the two sets of buffer pads to rotate around the center. At this time, the two sets of buffer pads form an acute angle, which can increase the buffering capacity while avoiding the problem of large water flow resistance during navigation caused by flat buffer pads, thus ensuring that navigation is not affected by the buffer pad.

[0021] In the following description, embodiments of the buffer device for berthing small vessels of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-6 This invention illustrates a small vessel berthing buffer device according to an embodiment of the present invention. It includes a hull 1, a drive box 2 fixedly installed inside the hull 1, an outer rod 3 mounted at one end of the drive box 2, an inner rod 4 movably mounted on one side of the outer rod 3, and a connecting rod 5 fixedly mounted at one end of the inner rod 4. A sleeve rod 6 has a groove at one end that mates with the connecting rod 5, and the inner rod 4 fits snugly against the sleeve rod 6. A buffer rod 9 is fixedly connected to the hull 1 at one end. The groove at one end of the 6 limits the movement of the 5, ensuring that the movement of the 5 does not deviate, thus making the overall operation more stable. Fixed rods 8 are fixedly mounted at both ends of the connecting rod 5. Buffer rods 9 are fixedly mounted on both sides of the hull 1, and a fixed ring 10 is fixedly mounted at one end of the buffer rod 9. A second spring 13 is mounted on one side of the fixed ring 10. One side of the buffer pad 12 is made of rubber. The 13 enables the 9 to perform buffering work. A gear at one end of the 9 can adjust the tension of the 13. A connecting rod 5 is fixedly mounted on one side of the fixed ring 10. A rotating block 15 is movably installed on one side of the connecting block 11 and the buffer rod 9, and a buffer pad 12 is fixedly installed on one side of the rotating block 15. One side of the arc plate 14 is set with an arc surface. The fixing ring 10 and the fixing rod 8 are matched, and the two ends of the fixing ring 10 are in contact with the fixing rod 8. The arc surface of 14 can better facilitate the compression and rotation of 12. At the same time, the setting of two sets of 8 is more conducive to the movement of 10, making the force more even. There are two sets of buffer pads 12, and the two sets of buffer pads 12 are rotatably connected. A first spring 7 is installed on one side of the outer rod 3, and a sleeve rod 6 is installed on one side of the first spring 7. The drive box 2 is equipped with a pneumatic device connected to the inner rod 4, and the outer rod 3 has a slot that matches the inner rod 4. The pneumatically driven 4 can also have a certain buffering effect, which is more conducive to the overall buffering performance. The sleeve rod 6 and the outer rod 3 are connected by the first spring 7. One end of the first spring 7 is fixedly installed with an arc plate 14, and the arc plate 14 matches the buffer pad 12.

[0023] Working principle: When using this utility model, the user starts the drive box 2 to displace the inner rod 4. When the inner rod 4 displaces, it drives the connecting rod 5 to displace as well. At this time, the connecting rod 5 moves to one side, thereby causing the fixed rod 8 to move to one side. The fixed rod 8 then compresses the fixed ring 10 to move to one side, simultaneously causing the connecting block 11 to displace. At this time, the second spring 13 is compressed by the fixed ring 10. When the connecting block 11 displaces, it no longer contacts the buffer pad 12. At this time, the fixed ring 10 drives the buffer rod 9 to displace, thereby causing the rotating block 15 to be pulled by the buffer rod 9. When the rotating block 15 moves, it causes the buffer pad 12 to move as well. At this time, the buffer pad 12 contacts the arc plate 14, and the middle part of the buffer pad 12 is blocked. When the rotating block 15 continues to move, the buffer pad 12 rotates around the middle part, thus forming an acute angle. When the ship 1 docks normally, the buffer pad 12 contacts the dock, causing the buffer pad 12 to be impacted. At this time, the connecting block 11 moves and compresses the second spring 13. At the same time, the arc plate 14 disperses the compressive force, causing the sleeve rod 6 to move to one side and compress the first spring 7, thus playing a buffering role.

[0024] In summary, this small vessel berthing buffer device, through the connection rod 5 and the fixed rod 8, allows the inner rod 4 to move the fixed rod 8 when the drive box 2 is activated, thereby pulling the fixed ring 10 to one side. At this time, the buffer rod 9 is displaced by tension, causing the rotating block 15 to rotate, which in turn causes the buffer pad 12 to rotate. When the buffer pad 12 rotates, it is limited by the arc plate 14, causing the two sets of buffer pads 12 to rotate around the center. At this time, the two sets of buffer pads 12 form an acute angle, which can increase the buffering capacity while avoiding the problem of large water flow resistance during navigation caused by the planar buffer pad 12, ensuring that navigation is not affected by the buffer pad 12.
