Description

Technical Field

[0001] The utility model belongs to the technical field of ship protection, and in particular relates to a ship anti-collision device. Background Art

[0002] Preventing direct collisions between the ship's side and the port's docking area to protect the hull from damage has always been a major challenge facing the shipping industry. Currently, many crews have adopted a simple and relatively low-cost solution: hanging discarded tires from the ship's side as anti-collision devices. This method utilizes the elasticity of rubber tires to absorb the impact of collisions, thereby providing a certain degree of protection. However, with the development of the shipping industry and increasing demands for ship safety performance, this traditional practice has gradually revealed its drawbacks.

[0003] First, waste tires, as anti-collision devices, have limited impact resistance and service life. Although rubber tires have a certain degree of elasticity, their deformation and recovery capabilities may not be sufficient to fully absorb the impact force when subjected to strong impacts, resulting in damage to the ship's side. Furthermore, the waste tires themselves are severely worn, even aging and cracking, resulting in reduced elasticity, which further weakens their impact resistance, making them less effective in protecting the ship's side.

[0004] Secondly, the weight of used tires cannot be ignored. A single used car tire can weigh 10 to 15 kilograms. If hung in large numbers on both sides of a ship, it will significantly increase the load burden on a small vessel, affecting its navigation performance and stability. This may not only increase fuel consumption but also adversely affect the ship's maneuverability and safety.

[0005] In summary, the existing method of using waste tires as ship collision avoidance devices has many shortcomings and cannot meet the high safety requirements of the modern shipping industry. Therefore, designing a collision avoidance device specifically for ships with excellent impact resistance and good durability to replace traditional waste tire collision avoidance methods is of great practical significance and market demand.

[0020] In order to better understand the present invention, Figures 1 to 3 The embodiments of the present invention will be explained in detail.

[0021] It should be noted that the directions “front, back, left, right, up, down” mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up and down” are used as the reference.

[0022] See also Figures 1 to 3 The present invention provides a ship anti-collision device comprising a base plate 2 made of a high-strength, corrosion-resistant material, such as stainless steel or aluminum alloy, to ensure long-term stability and reliability. The bottom surface of the base plate 2 is provided with a plurality of mounting holes 19. These mounting holes 19 correspond to screws 18 pre-welded on the ship's side 1. By inserting the screws 18 and tightening the nuts 20, the base plate 2 is removably connected to the ship's side 1.

[0023] like Figure 1 As shown in FIG, parallel grooves 3 are machined on both sides of the top surface of the base plate 2, and a slider 4 is disposed in each groove 3. A spring 5 is installed between the slider 4 and the groove 3. When the spring is in a compressed state, it continuously applies an outward expansion force to the slider 4, thereby maintaining the slider 4 in the predetermined position within the groove 3.

[0024] On one side of the base plate 2, a parallel fixed plate 6 is installed. Two supporting links 7 are connected to the bottom surface of the fixed plate 6. One end of the supporting link 7 is hinged to the fixed plate 6, and the other end is hinged to the corresponding slider 4, forming an articulated four-bar mechanism with automatic reset capability. When the ship is struck, the elastic anti-collision plate 8 and the fixed plate 6 are subjected to pressure. The rotation of the supporting link 7 and the sliding of the slider 4 in the chute 3, which compresses and expands the spring 5, absorb the impact force and convert it into stored elastic potential energy.

[0025] An elastic anti-collision plate 8 is mounted (e.g., glued) on the front end of the fixed plate 6. This anti-collision plate is made of highly elastic rubber and has a corrugated top surface 12 to further enhance its energy absorption and impact resistance. A tension spring 9 is also installed between each supporting link 7 and the adjacent end of the fixed plate 6. The function of the tension spring 9 is to maintain the fixed plate 6 and its elastic anti-collision plate 8 in a neutral state (parallel to the base plate 2) when no external force is applied. In the event of an impact, the tension spring 9 can help absorb and disperse the impact force.

[0026] To limit the maximum movement of the slider 4 within the chute 3 and prevent damage to the device due to excessive movement, an upwardly extending elastic stopper 10 is provided between the two chute 3s. The extension height of the elastic stopper 10 is slightly greater than the height of the slider 4. When the slider 4 is impacted and slides outward, if the fixed plate 6 approaches the base plate 2 too closely, the fixed plate 6 first contacts the elastic stopper 10 and is prevented from further movement. The elastic stopper 10 serves as a final buffer, thereby ensuring the overall stability and safety of the anti-collision device. In addition, the elastic stopper 10 is designed with a T-slot, and the base plate 2 is provided with a T-block 15 that matches the T-slot. A stopper plate 16 is provided to limit and fix the position of the elastic stopper 10 on the T-block 15, thereby increasing the stability of the elastic stopper 10.

[0027] In order to prevent the expansion spring 5 from bending due to rapid compression when the slider 4 slides, a fixed shaft 13 is fixed on each slider 4 and is passed into the spring. An axial hole 14 that is compatible with the fixed shaft 13 is provided at one end of the slide groove 3 to ensure smooth expansion and contraction and positioning of the spring in the slide groove 3.

[0028] In order to improve the stability and shock absorption effect of the connection, a layer of rubber pad can be added between the bottom plate 2 and the side of the ship 1. The rubber pad is embedded with a mesh interlayer, which not only enhances the shock absorption ability but also prevents the rubber pad from cracking due to aging during long-term use.

[0029] In order to improve the energy absorption effect of the anti-collision device, energy absorption cavities 17 with openings at both ends can be opened inside the elastic anti-collision plate 8 and the elastic limit block 10. These energy absorption cavities 17 can deform when impacted to absorb and store more energy.

[0030] The usage and principle of this utility model:

[0031] The anti-collision device is installed on the side of the ship 1 on both sides, and several devices are set according to the size of the ship. During installation, the bottom plate 2 is first fixed to the side of the ship 1 by means of screws 18 and nuts 20 to ensure a firm connection. Subsequently, check whether each component is installed in place, especially key components such as the expansion spring 5, tension spring 9 and elastic limit block 10, to ensure that they are in normal working condition. During the docking process of the ship, when the side 1 collides with the port berthing point, the elastic anti-collision plate 8 first contacts and absorbs part of the impact force, and then, through the synergistic action of the articulated four-bar mechanism and the expansion spring 5 and tension spring 9, the remaining impact force is converted into elastic potential energy and stored, and the sliding of the slider 4 and the limiting action of the elastic limit block 10 prevent the impact force from causing direct damage to the side 1. Throughout the process, the design of the vibration damping pad 11 and the elastic anti-collision plate 8 also further enhances the vibration reduction and energy absorption effect of the device, thereby achieving comprehensive protection of the side 1.
