Abstract
Description
Technical Field
[0001] This utility model relates to the field of ship collision avoidance technology, specifically to a ship collision avoidance device. Background Technology
[0002] In the field of existing ship collision avoidance technology, although a variety of devices and technologies have been proposed and applied in practice, these devices and technologies often have certain limitations. For example, most traditional ship collision avoidance devices rely on simple physical structures, such as directly setting up anti-collision plates or anti-collision pads on the outside of the ship. When faced with a violent collision, these devices often cannot effectively absorb and disperse the impact force, resulting in damage to the ship structure and even causing more serious safety accidents.
[0003] Publication No. CN220181059U discloses a ship collision avoidance device, including a ship. Grooves are formed on both sides of the ship, and inner slots are formed inside the grooves. Connecting blocks are inserted into the inner slots, and connecting blocks are connected to both sides of the connecting blocks. A connecting plate is provided at the lower end of the connecting blocks, and a stop plate is fixed to the outer side of the connecting plate. This invention uses a rubber material on the arc-shaped buffer elastic plate of the second buffer component to initially buffer the impact force. The first and second buffer springs in the first and second buffer components compress and move to further buffer the impact force. The rubber material of the buffer pad further buffers the impact force, solving the problem that existing collision avoidance devices have simple structures and cannot filter violent collisions.
[0004] The above still has the following problems: The design uses rubber material to initially buffer the impact force by setting the arc-shaped buffer elastic plate on the buffer component two, and combines the buffer springs one and two in the buffer components one and two for secondary buffering, as well as the rubber material of the buffer pad for further buffering. However, this design still has certain shortcomings. First, its buffering mechanism is relatively simple, mainly relying on the elasticity of the rubber material and the compression of the buffer spring to absorb the impact force. The buffering effect of this method is limited, especially when facing extremely harsh sea conditions and strong collisions, it may not provide sufficient protection.
[0005] In view of this, we will study and improve the existing structure and its shortcomings, and provide a ship collision avoidance device in order to achieve a more practical value. Utility Model Content

[0029] Working Principle: The equipment is first fixed to a suitable position on the ship via the mounting plate 1 and its surrounding mounting holes. The limiting block 14 and the sliding groove ensure the stable installation of the housing 2 on the mounting plate 1 and allow for a certain range of movement. When the ship is impacted, the first components to come into contact with are the protective plate 3 and the arc-shaped pad 4. These components absorb some of the impact energy, reducing the impact force. The shock-absorbing ring 6 inside the arc-shaped pad 4 further enhances the buffering effect, making the impact softer. When the impact force is transmitted to the housing 2, the movable plate 5 and the push plate 7 begin to function. The push plate 7 is connected to the protective plate 3 via the fixed rod 9. When an impact occurs, the push plate 7 moves backward, compressing the buffer spring 10 to further absorb the impact energy. At the same time, the movable plate 5 also moves backward under the action of the damping rod 12 and the shock-absorbing spring 13, forming an elastic buffer. The combination of the damping rod 12 and the shock-absorbing spring 13 can... To effectively mitigate the vibrations caused by impacts and protect the ship's structure from damage, the guide block 15 ensures that the housing 2 can move in a predetermined direction when impacted, avoiding unnecessary deviation and damage. The guide block 15 slides within the groove of the limiting block 14 via a slider. Simultaneously, the combination of the guide rod 16 and the limiting spring 17 forms an additional buffer. When the guide block 15 moves, the limiting spring 17 is compressed, further absorbing impact energy, and the limiting disc 18 prevents the guide rod 16 from moving excessively. The shock absorber 11 is located at the front end of the guide block 15, and the tilt angles on both sides of its outer end correspond to the tilt angles on the inner side of the guide block 15. This design allows the shock absorber 11 to closely cooperate with the guide block 15 when it moves, forming a more stable buffer. The shock absorber 11 not only enhances the buffering effect but also ensures the stability of the housing 2 during movement.
