Description

Technical Field

[0001] This utility model relates to the field of ship hull technology, and in particular to a collision-resistant ship hull structure. Background Technology

[0002] In ship design, collision avoidance hull structures typically combine material selection, structural layering, and energy absorption mechanisms to achieve impact resistance.

[0003] Patent specification CN215972018U discloses a collision-resistant composite material hull, including a hull body and protective mechanisms installed on both sides of the hull body. The protective mechanisms include impact pillars and connecting rods installed on both sides of the impact pillars. One end of the connecting rod is connected to a movable block, and both ends of the connecting rod are installed on the sides of the impact pillar and the movable block through connectors. Buffer springs A are provided on both sides of the movable block. A fixed rod is provided on the inner side of the impact pillar, and a buffer spring B is provided on the outer side of the fixed rod. If an object impacts from the side, the impact pillar is compressed and moves inward. The force from both sides is transmitted to the movable block through the connecting rods on both sides. The force on the impact pillar is dispersed by the use of buffer springs A and B. The rebound force of buffer springs A and B bounces the impact pillar outward, thereby ejecting the impacting object and preventing damage to the hull body due to the impact.

[0004] However, in implementing the relevant technology, the above-mentioned collision-resistant composite material hull has the following problems: by using buffer spring A and buffer spring B, the force on the impact column is dispersed to avoid damage to the hull body due to impact. However, the buffering mechanism relies on the linear energy absorption of the spring, which is not effective in dispersing oblique or high-speed impacts. When subjected to oblique impact, the fixing rod and support tube may undergo plastic deformation, resulting in permanent structural damage and affecting reusability. In view of this, a collision-resistant hull structure is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a collision-resistant hull structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a collision-resistant hull structure, comprising a hull body, with fixed bases fixedly connected to the left and right ends of the hull body, a rotating shaft rotatably connected to the outer side of the fixed base, a telescopic rod fixedly connected to the outer side of the rotating shaft, a first spring provided on the outer side of the telescopic rod, a fixed ring fixedly connected to the end of the telescopic rod away from the rotating shaft, a linkage ring fixedly connected to the outer side of the telescopic rod, a linkage rod rotatably connected to the front end of the linkage ring, a moving block rotatably connected to the end of the linkage rod away from the linkage ring, second springs fixedly connected to both sides of the front end of the moving block, a pin attached to the outer side of the fixed ring, a structural support layer fixedly connected to the outer side of the pin, an energy-absorbing buffer layer fixedly connected to the outer side of the structural support layer, and an outer impact-resistant layer fixedly connected to the outer side of the energy-absorbing buffer layer.

[0007] As a further description of the above technical solution: the inner side of the first spring is fixedly connected to the outer side of the rotating shaft, the end of the first spring away from the rotating shaft is fixedly connected to the inner side of the linkage ring, and the end of the second spring away from the moving block is fixedly connected to the inside of the fixed base. The compression of the first spring buffers the external impact.

[0008] As a further description of the above technical solution: a square groove is provided at the right end of the fixed base, and the shape and size of the cross-section of the square groove are matched with the diameter and vertical length of the rotating shaft, so that the rotating shaft can drive the outer telescopic rod to rotate, thereby facilitating the compression and buffering of the first spring.

[0009] As a further description of the above technical solution: the right end of the fixed base is provided with a positioning groove, and the vertical length of the positioning groove matches the vertical length of the moving block, so that the second spring is compressed or stretched by the movement of the moving block inside the positioning groove, and the linkage rod provides auxiliary buffering against the impact.

[0010] As a further description of the above technical solution: a circular groove is provided at the right end of the fixing ring, and the diameter of the circular groove matches the diameter of the pin. Both the upper and lower ends of the fixing ring and the pin are provided with through circular holes, and the inner wall of the circular holes is provided with threads. The circular groove at the right end of the fixing ring is interconnected with the circular holes. The fixing ring and the pin are fixed by passing a bolt through the circular holes.

[0011] As a further description of the above technical solution: the fixed base is provided with flexible skirts at both the upper and lower ends, and airbags are provided inside the flexible skirts. The airbags increase the buoyancy reserve of the ship and improve the stability of the ship.

[0012] As a further description of the above technical solution: the flexible skirt has an accommodating cavity inside, and the inner contour of the accommodating cavity matches the outer contour of the airbag. The flexible skirt prevents debris from getting stuck in the shock absorption device, and the compression deformation of the airbag provides secondary buffering, forming double protection.

[0013] This utility model has the following beneficial effects:

[0014] The anti-collision hull structure designed in this utility model, through the design and cooperation of the linkage ring and the first spring, enables the device to not only buffer lateral impacts, but also, when facing oblique impacts, cause the structural support layer to deform, drive the rotating shaft to rotate, and cause the telescopic rod to deflect, so that the angle of the telescopic rod is deflected in the direction of impact. This allows the first spring and the second spring to buffer the oblique impacts and avoid rigid damage to the device.

[0015] The collision-resistant hull structure designed in this utility model combines flexible skirts with airbags. By adding flexible skirts to the upper and lower ends of the shock-absorbing device, various debris is prevented from entering the decompression device, thus ensuring its normal operation and long-term durability. By setting airbags inside the flexible skirts, not only is the stability of the ship improved, but the compression deformation of the airbags also provides secondary buffering, forming double protection and further improving the ship's collision-resistant performance.

The compression of the first spring 5 buffers the external impact.

[0026] As a further implementation of the above technical solution: a square groove is provided at the right end of the fixed base 2, and the shape and size of the cross-section of the square groove are matched with the diameter and vertical length of the rotating shaft 3, so that the rotating shaft 3 can drive the outer telescopic rod 4 to rotate, thereby facilitating the compression and buffering of the first spring 5.

[0027] As a further implementation of the above technical solution: a positioning groove is provided at the right end of the fixed base 2, and the vertical length of the positioning groove matches the vertical length of the moving block 9, so that the second spring 10 is compressed or stretched by the movement of the moving block 9 inside the positioning groove, and the linkage rod 8 provides auxiliary buffering against the impact.

[0028] As a further implementation of the above technical solution: a circular groove is provided at the right end of the fixing ring 7, and the diameter of the circular groove matches the diameter of the pin 11. Both the upper and lower ends of the fixing ring 7 and the pin 11 are provided with through circular holes, and the inner wall of the circular holes is provided with threads. The inside of the circular groove at the right end of the fixing ring is connected to the circular holes. The fixing ring 7 and the pin 11 are fixed by passing a bolt through the circular holes.

[0029] As a further implementation of the above technical solution: flexible skirts 15 are provided at the upper and lower ends of the fixed base 2, and airbags 16 are provided inside the flexible skirts 15. The airbags 16 increase the buoyancy reserve of the ship and improve the stability of the ship.

[0030] As a further implementation of the above technical solution: the flexible skirt 15 is provided with a receiving cavity, and the inner contour of the receiving cavity matches the outer contour of the airbag 16. The flexible skirt 15 prevents debris from getting stuck in the shock absorption device, while the compression deformation of the airbag 16 provides secondary buffering, forming double protection.

[0031] Working principle:

[0032] When using this invention, when the ship body 1 is impacted, the outer impact-resistant layer 14 can resist minor collisions and scratches, while guiding the impact force to the energy-absorbing buffer layer 13. After the impact force is transmitted to the energy-absorbing buffer layer 13, a large amount of impact energy is absorbed through material deformation. The structural support layer 12 can disperse the remaining impact force to prevent damage to the ship structure. When subjected to a strong impact from an inclined plane, the structural support layer 12 deforms and indents inward. The pin 11 drives the fixing ring 7 to move, thereby causing the fixing ring 7 to drive the first spring 5 to rotate around the pivot 3 inside the fixed base 2, adjusting the angle of the telescopic rod 4 to the impact point. This causes the linkage ring 6 to compress the telescopic rod 4 and the first spring 5, thereby buffering the impact. At the same time, the linkage rod... 8. The movable block 9 is moved, causing the second springs 10 on both sides of the movable block 9 to compress or extend, providing auxiliary buffering against impact. The adjacent structural support layers 12 are connected to each other by bolts, which facilitates the overall protection of both sides of the ship by the structural support layers 12. At the same time, the first and second springs 10 in other areas provide buffering, improving the anti-collision performance. Meanwhile, the flexible skirt 15 can prevent various debris from entering the decompression device, thus ensuring its normal operation and long-term durability. By setting airbags 16 inside the flexible skirt 15, not only is the stability of the ship improved, but additional benefits are also provided after the hull leaks. At the same time, the compression deformation of the airbags 16 can provide secondary buffering, forming double protection and further improving the ship's anti-collision performance.
