[0001] This application relates to the field of marine machinery parts and devices, specifically a marine protective enclosure part. Background Technology

[0002] Ships frequently face the risk of collisions with other vessels, docks, buoys, and other objects during navigation, berthing, and operations. These collisions can lead to serious consequences such as structural damage to the ship, personal injury, and environmental pollution. Therefore, improving the safety and stability of ships and reducing collision damage is a crucial issue in ship design and operation. Currently, ship protection mainly relies on the strength of the hull structure itself and some passive protective measures, such as rams made of highly elastic materials. However, these traditional protective measures have certain limitations. The installation of rams requires pre-installed anchoring pins or ram horns, which is inconvenient, and rams are prone to falling into the water, with limited effectiveness in practical applications. Therefore, this application provides a ship protective enclosure accessory that can effectively absorb and disperse collision energy to reduce damage to the ship's structure from collisions.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0028] In order to solve the technical problems in the background art, such as Figure 1-4 As shown, this application provides a technical solution: a ship protective enclosure accessory, characterized as follows:

[0029] The design of the guardrail 1 conforms to the shape of the stern of the ship. This contoured design matches the shape of the stern, providing a protective barrier and effectively preventing impacts during berthing or navigation. The guardrail 1 consists of a first guardrail 2 and a second guardrail 3, connected by a connecting rod 4 to form a stable enclosure structure. One end of a fixing rod 5 is connected to each of the first and second guardrails 2 and 3, respectively. The other end of the fixing rod 5 is equipped with a buffer device 6, which is connected to the hull to mitigate the impact force during a collision. Specifically, the middle part of the buffer device 6 is a central shaft 7 movably connected to the fixing rod 5. The central shaft 7 has external threads for easy connection to a gasket 10. The central shaft 7 is inserted into the fixing rod 5, and an anti-detachment sleeve or hook device is provided between them to prevent detachment. A positioning piece 8 is movably fitted onto one end of the central shaft 7, and the positioning piece 8 is fixedly connected to the fixing rod 5. The area of ​​the positioning piece 8 is larger than that of the fixing rod 5, which increases the area of ​​the spring 11, thereby improving stability during impact buffering. The other end of the central shaft 7 is provided with a pin hole 9, which can be connected to a pre-drilled hole in the hull of the ship via a pin, thereby firmly fixing the enclosure accessories to the stern of the ship. The gasket 10 has internal threads and is threadedly connected to the central shaft 7, serving to fix and support the spring 11. The spring 11 is sleeved on the central shaft 7, with one end abutting against the positioning piece 8 and the other end fixedly connected to the gasket 10. When subjected to external force, the spring 11 can buffer and reset. The anti-collision block 12 is a cylindrical structure, sleeved on the connecting rod 4. Its function is to absorb some of the impact energy and reduce damage to the enclosure 1 when the ship collides.

[0030] It should be noted that the two ends of the U-shaped post 13 are connected to the first guardrail 2 and the second guardrail 3 respectively, forming a more robust enclosure structure, thereby significantly improving the impact resistance and structural stability of the guardrail 1. The U-shaped post 13 is made of metal or high-strength composite material, and is U-shaped, with connecting structures at both ends for connection to the first guardrail 2 and the second guardrail 3. As an additional support point, the U-shaped post 13 can better disperse and withstand the impact force on the stern of the ship, reducing direct pressure on the connecting rod 4 and the fixing rod 5. The addition of the U-shaped post 13 enhances the bending resistance of the guardrail 1, allowing the entire structure to better maintain its shape and position when facing lateral or transverse impacts. By transferring the impact force to a wider area through the U-shaped post 13, local stress concentration is reduced, thereby lowering the risk of structural damage due to impact.

[0031] Furthermore, two protective wings 14 are provided, located on both sides of the U-shaped post 13. The main function of the protective wings 14 is to improve the impact resistance of the U-shaped post 13, protecting it from damage when subjected to external impacts. The protective wings 14 on both sides of the U-shaped post 13 effectively protect the sides of the stern of the ship from impacts, providing an additional protective layer and enhancing the overall protective capability. As an additional protective structure, the protective wings 14 can disperse and absorb more impact force when the ship collides with other ships, docks, etc., during berthing or navigation, reducing damage to the main structure. The installation of the protective wings 14 enhances the lateral stability of the enclosure 1, especially in severe sea conditions, reducing deformation of the enclosure 1 and maintaining its structural integrity.

[0032] It should be noted that the placement of the crash bar 15 at one end of the protective wing 14 provides more robust end protection, significantly enhancing the overall protection level of the containment system. As a reinforcing structure, the crash bar 15 can withstand greater impact forces, especially when the vessel is berthing or navigating in narrow waters, effectively reducing direct impacts to the stern. The crash bar 15 enhances the stability of the protective wing 14, preventing it from twisting or deforming under strong lateral forces. The crash bar 15 is typically designed for quick disassembly, allowing for rapid removal when maintenance or replacement is needed, improving maintenance efficiency. The crash bar 15 usually uses highly visible colors or reflective materials, increasing the visibility of the vessel's stern and serving as a warning to other vessels and obstacles.

[0033] Furthermore, a through hole 17 is provided on the connecting rod 4. The diameter of the through hole 17 is slightly larger than the diameter of the anti-loss rope, and it is used to fix the anti-loss rope of the ship rivet. By providing a through hole 17 on the connecting rod 4, the anti-loss rope can be easily installed and fixed, making the use of the ship rivet more flexible and convenient, and improving the practicality of the fencing accessories. The through hole 17 allows for further strengthening of the stability of the ship rivet by fixing the anti-loss rope, preventing the ship rivet from being lost due to unexpected forces, thereby improving the safety of the ship in complex waters.

[0034] It should be noted that grooves 16 are provided around the periphery of the gasket 10, as shown in the figure. The grooves 16 are semi-circular in shape. The evenly distributed grooves 16 help to achieve a more uniform stress distribution around the gasket 10, reduce local stress concentration, and thus improve the durability and reliability of the structure. At the same time, operators can easily select the most suitable groove 16 to tighten or loosen the gasket 10 and adjust the fit between the gasket 10 and the spring 11, improving the efficiency of maintenance and operation.

[0035] It should be noted that the protective wing 14 is arranged parallel to the first guardrail 2 and the second guardrail 3. The parallel arrangement of the protective wing 14 increases the lateral support of the enclosure system and improves the overall structural stability. The parallel arrangement of the protective wing 14 helps to distribute the impact force more evenly, reducing the pressure on a single structural point, thereby reducing the risk of structural damage.

[0036] It should be noted that the diameter of the crash barrier 15 is designed to be larger than that of the protective wing 14, meaning it has a larger cross-sectional area, can withstand greater impact forces, and provides stronger protection. The larger crash barrier 15 can better absorb and disperse impact energy, reducing the impact on the main structure of the protective wing 14. As a reinforcing structure of the protective wing 14, the larger diameter of the crash barrier 15 helps to improve the structural strength of the entire enclosure system.

[0037] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
