[0002] During the navigation of a ship, collision accidents may occur due to various reasons, and the side of the ship is the part most vulnerable to collision impact. The traditional ship side structure has certain limitations in anti - collision, and it is difficult to effectively reduce the damage caused by collisions, which not only threatens the safety of the ship, but may also lead to serious environmental pollution and economic losses. Content of the Utility Model

[0004] The technical solution adopted by the utility model is: a ship side enhanced anti - collision structure device, which includes a buffer layer, a strengthening framework and an energy absorber. The energy absorber includes an external energy absorption housing and an internal energy absorption component; the energy absorption component is arranged on the strengthening framework through a fixing member; the energy absorption housing includes a bottom wall, a side wall and an end wall;

[0005] The energy absorber is in a trapezoidal frustum structure, and the energy absorber is filled with gas; the radial distance of the energy absorption component gradually increases in the direction from the strengthening framework to the bottom wall.

[0006] 3 - 5 groups of energy absorption components are arranged in the energy absorber.

[0007] The energy absorption component adopts a spring.

[0008] The device is also provided with a collision detection sensor, which is arranged on the bottom wall corresponding to the energy absorption component.

[0009] Furthermore, the buffer layer is located on the outermost layer of the ship side and is made of a highly elastic and impact - resistant rubber material; the strengthening framework is arranged inside the buffer layer and is welded by high - strength steel to form a stable framework structure; the energy absorption component is installed inside the strengthening framework and consists of a series of springs.

[0010] In addition, a collision monitoring sensor is installed on the ship side, which can monitor the occurrence and intensity of collisions in real time and transmit relevant information to the ship control system for timely taking emergency measures.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The buffer layer can absorb part of the impact energy in the initial stage of collision and reduce the direct damage of the collision to the side shell of the ship. The strengthening framework provides the overall structural strength and prevents serious deformation of the side during collision. The energy absorption components are all filled with gas and absorb a large amount of impact energy through their own deformation and destruction during the collision. After the collision, the deformed part can be restored by the air pressure, thereby further reducing the impact of the collision on the main structure of the ship. The synergistic effect of the buffer layer, the strengthening framework and the energy absorption components significantly improves the anti-collision ability of the ship's bow and effectively reduces the structural damage and safety risks caused by the collision. The application of the collision monitoring sensor realizes the real-time monitoring and early warning of the collision situation and provides timely and accurate information support for the ship to take emergency measures. This device significantly improves the anti-collision ability of the ship's side, reduces the collision damage, structural damage, safety risks and economic losses, and ensures the navigation safety of the ship and environmental protection.

[0017] Please refer to FIG. 1 and Figure 2, A ship's bow enhanced anti-collision structure device, including a buffer layer 1, a strengthening framework 2, and an energy absorber. The buffer layer 1 is made of a special high-elasticity rubber material and is attached to the outer surface of the ship's bow. The strengthening framework 2 is welded by high-strength I-beams to form a firm framework structure. The fixing piece 5 is connected and fixed to the strengthening framework 2 with screws to enhance the stability between the strengthening structures. The energy absorber includes an outer energy absorption housing 4 and an inner energy absorption component 3; the energy absorption component 3 is arranged on the strengthening framework 2 through the fixing piece 5; the energy absorption housing 4 includes a bottom wall 4a, side walls 4b, and end walls 4c. The energy absorber is in a trapezoidal frustum structure, and the energy absorber is filled with gas; the radial distance of the energy absorption component 3 gradually increases in the direction from the strengthening framework 2 to the bottom wall 4a. 3 - 5 groups of energy absorption components 3 are arranged in the energy absorber, and the energy absorption component 3 uses springs; they are evenly arranged on the strengthening framework 2. The collision monitoring sensor 4 is installed at key positions on the ship's bow and is connected to the ship's control system.

[0018] The buffer layer is located in the outermost layer at the forefront of the ship's side and is made of a rubber material with an ultra-high elastic modulus and excellent impact resistance. At the initial moment when the ship inevitably encounters a collision, the buffer layer 1, relying on the mechanical properties of its material, takes the lead in bearing and dispersing the impact force generated by the collision, efficiently absorbing and reducing the impact energy, and reducing the direct impact strength on the ship's side structure, thus winning crucial buffer time and energy reduction window for the subsequent protection structure.

[0019] The strengthening framework 2 is arranged inside the buffer layer 1 and is a framework structure welded by high-strength steel. This framework not only provides a solid support foundation for the buffer layer, greatly enhancing the stability and rigidity of the overall structure, but also can, in the extremely critical moment when a collision occurs, rely on the high-strength mechanical properties of the steel itself and the reliability of the welding joints to resist the impact force. It effectively curbs the possible serious structural damage on the ship's side, ensuring the basic integrity of the ship and its continuous navigation ability in case of damage.

[0020] The energy absorption component is installed behind the strengthening framework and consists of a series of spring components. When the collision force breaks through the defense line of the buffer layer and is transmitted to the inside of the strengthening framework, the energy absorption component 3 quickly plays a key role in further absorbing and converting the remaining impact energy. Through its internal physical deformation, energy transfer, and dissipation mechanisms, the impact energy is converted into relatively mild other forms of energy, such as heat energy and internal energy, etc., so as to minimize the collision energy transmitted to the main structure of the ship, avoid damage to the key structures, precision equipment, and important systems inside the ship, and maintain the basic functions and safety of the ship after the collision.

[0021] During an actual collision, the buffer layer 1 first comes into contact with the colliding object and absorbs part of the impact energy through its own elastic deformation. Subsequently, the strengthening framework 2 bears the collision force and maintains the basic shape of the side structure. The energy absorber is filled with gas. First, the collision energy is consumed through the deformation of the internal gas, and then a large amount of energy is further absorbed through the compression and deformation of the energy absorption component 3, minimizing the damage to the main structure of the ship caused by the collision. The collision monitoring sensor 4 transmits the collision information to the control system in real time, triggering corresponding emergency measures such as alarm, deceleration, and steering.

[0022] This device is closely integrated by a buffer layer, a strengthening framework, an energy absorption assembly, and a collision monitoring sensor, each playing a unique and indispensable role, and working together to build a solid protection system. In the application of actual complex navigation scenarios, the anti-collision structure device for strengthening the bow of the ship of the present utility model forms a stable and reliable protection system through the rapid initial energy reduction of the buffer layer, the strong support and resistance of the strengthening framework, and the deep and fine energy conversion of the energy absorption component. This innovative design significantly improves the anti-collision ability of the ship's bow, enabling it to calmly handle various potential collision threats in the marine navigation environment full of uncertainties and risks, and building an indestructible protection barrier for the safe navigation of the ship and the life and property safety of the crew on board.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model.
