Description

Technical Field

[0001] This utility model belongs to the field of unmanned surface vessel fender technology, and more specifically, relates to an unmanned surface vessel fender structure. Background Technology

[0002] With the rapid development of the modern shipbuilding industry, the use of unmanned surface vessels (USVs) is increasing. In high sea states, the recovery of USVs faces the risk of collision damage, affecting not only the safety of the mother ship and the USV's hull structure but also subsequent operations. Currently, while the use of USVs in the shipbuilding industry is growing, collision avoidance technologies and devices for USV recovery are relatively rare. Known collision avoidance measures fall into two categories: active collision avoidance technology and passive collision avoidance technology. Active collision avoidance technology relies on image recognition algorithms and artificial intelligence, but in the complex maritime environment, it is difficult to completely avoid sudden wave impacts due to technological limitations, making USV recovery highly susceptible to collision damage. Passive collision avoidance devices are installed inside the ship's dock to prevent collision damage caused by inertia and ship swaying after the USV is recovered into the mother ship. However, in maritime recovery operations, collisions are often located in the stern door area of ​​the mother ship due to the influence of waves. In conclusion, existing technologies cannot effectively prevent collision damage during USV recovery operations.

[0003] Existing technology includes a designation titled "A Rotating Dock Rubber Fender" with publication number CN205907655U. This technology discloses a rotating dock rubber fender comprising a rubber body with an internal cavity containing an air bladder. One side of the rubber body has an arc-shaped structure, and the other side has multiple connecting rods arranged in an array. A base plate is located on the side of the rubber body away from its arc-shaped surface, and a groove is provided on the base plate. A locking block is located at the bottom of the groove and is connected to the rubber body via the connecting rods. A limiting block corresponding to the locking block is provided on the side wall of the groove. A spring is sleeved on the connecting rod, with one end of the spring connected to the outer surface of the rubber body and the other end abutting against the outer surface of the base plate. A rotating shaft is located at one end of the base plate, and L-shaped fixing members are provided at both ends of the rotating shaft. The base plate is rotatably connected to the L-shaped fixing members via the rotating shaft. This utility model has a simple structure, is easy to use, is rotatable, prevents seawater corrosion, and extends its service life. However, this technology does not address the technical problems and solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a simple structure, easy installation, and effective way to offset the impact energy generated by the collision between the unmanned surface vessel and the mother ship during unmanned surface vessel recovery, thereby avoiding structural damage to the mother ship and the unmanned surface vessel and protecting the unmanned surface vessel fender structure of the mother ship and the unmanned surface vessel.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a fender structure for an unmanned surface vessel. The fender body includes an L-shaped surface, a collision protection surface, and a nut. The L-shaped surface is provided with stud mounting holes, and the collision protection surface is provided with openings. Each opening is aligned with a stud mounting hole, and studs are provided at the stern door position of the unmanned surface vessel.

[0006] The L-shaped surface includes a first surface and a second surface, which are L-shaped. Multiple stud mounting holes are provided on the first surface and the second surface respectively, and the multiple stud mounting holes are arranged with gaps between them.

[0007] The anti-collision surface is provided with openings at the positions of each stud mounting hole on the first side, and the anti-collision surface is provided with openings at the positions of each stud mounting hole on the second side.

[0008] The L-shaped surface and the anti-collision surface are an integrated structure.

[0009] The stern door of the unmanned surface vessel includes an outer side and an inner side, which are L-shaped.

[0010] Studs corresponding to the number and position of the stud mounting holes on the first surface are welded to the outer side of the stern door position, and studs corresponding to the number and position of the stud mounting holes on the first surface are welded to the inner side of the stern door position.

[0011] When the fender body is installed at the stern door position, the first surface of the L-shaped surface fits against the inner surface of the stern door position, each stud passes through the corresponding stud mounting hole, and a nut is screwed onto the outer end of each stud mounting hole.

[0012] When the fender body 1 is installed at the stern door position, the second side of the L-shaped surface fits against the outer side of the stern door position, each stud passes through the corresponding stud mounting hole, and a nut is screwed onto the outer end of each stud mounting hole.

[0013] When the fender body is installed at the stern door position, a pressure plate is set between the first surface of the L-shaped surface and the nut, and each stud passes through the corresponding through hole on the pressure plate.

[0014] The diameter of the opening is larger than the diameter of the stud mounting hole.

[0015] The working principle and beneficial effects of this utility model are as follows: The fender structure of this utility model is made of rubber material, integrally molded, with a hollow structure in the middle. The fender body is a long strip structure with an L-shaped surface, a collision-resistant surface, and nuts. The L-shaped surface is used to fit and connect to the stern door of the unmanned surface, while the collision-resistant surface faces outward to provide collision protection. Studs are fixedly installed at the stern door of the unmanned surface, and stud mounting holes are provided on the L-shaped surface. When the fender body is installed, each stud passes through a stud mounting hole, and then a nut is screwed onto the stud to secure the fender body. The fender body protrudes from the outside of the unmanned surface, reliably providing collision protection, while the rubber material is flexible, has good cushioning performance, and can repeatedly provide collision protection. When using the fender body, select the area to be protected at the stern door of the unmanned surface vessel (USV), choose a fender body of appropriate length, and mark the stern door with crosshairs according to the position of the stud mounting holes on the fender body to determine the welding position of the studs, ensuring precise welding positioning. Use a stud welding machine to weld each stud to its designated position, ensuring the welding position matches the positioning position as closely as possible. After all studs are welded, install the rubber fender body, securing it to the studs, ensuring each stud passes through its corresponding mounting hole, with the L-shaped surface 7 as close as possible to the mounting surface of the hull structure. Install all nuts and washers on the studs, and tighten the nuts with a hex wrench through the pre-drilled holes to ensure the fender body is securely installed and does not shift. This invention features convenient installation, low cost, moderate reaction force, and high energy absorption, effectively reducing or preventing structural damage to the mother ship and USV, providing reliable protection.

A stud 6 is installed at the stern door position 11 of the USV 10. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this design, the fender body 1 is made of rubber material, integrally molded, and has a hollow structure in the middle. The fender body 1 is generally elongated. The L-shaped surface 7, collision-resistant surface 8, and nut 5 are used to attach and connect to the stern door position 11 of the USV 10. The collision-resistant surface 8 faces outwards, providing a collision protection function. Studs are fixedly installed at the stern door position 11 of the unmanned surface vessel 10. Stud mounting holes 9 are provided on the L-shaped surface 7. When the fender body 1 is installed in place, each stud passes through a stud mounting hole 9, and then a nut 5 is screwed onto the stud 6 to achieve fixed installation of the fender body 1. The fender body 1 protrudes from the outside of the unmanned surface vessel 10, reliably providing collision protection. The rubber material is flexible, has good cushioning performance, and can repeatedly provide collision protection. When using the fender body 1, select the area to be protected at the stern door position 11 of the unmanned surface vessel 11, select a fender body 1 of appropriate length, and mark the stern door position 11 with crosshairs according to the position of the stud mounting holes 9 on the fender body to determine the welding position of the studs 6, ensuring precise welding positioning. Use a stud welding machine to weld the studs 6 one by one to the determined positions, ensuring the welding position of the studs 6 is as consistent as possible with the positioning position. After all the studs 6 are welded, install the rubber material fender body 1, securing the fender body 1 and studs 6 together, i.e., each stud 6 passes through the corresponding stud mounting hole 9, with the L-shaped surface 7 fitting as close as possible to the mounting surface of the hull structure. Install all nuts 5 and washers 2 onto the studs 6 one by one, and tighten the nuts 5 with a hex wrench through the opening 4 to ensure the fender body 1 is firmly installed and does not shift. This utility model has the characteristics of convenient installation, low cost, moderate reaction force, and high energy absorption, effectively reducing or avoiding structural damage to the mother ship and unmanned surface vessel, providing reliable protection. The unmanned surface vessel fender structure described in this utility model is simple in structure and easy to install. It can effectively offset the impact energy generated by the collision between the unmanned surface vessel and the mother ship during the recovery, thereby avoiding structural damage to the mother ship and the unmanned surface vessel and protecting the mother ship and the unmanned surface vessel.

[0018] The L-shaped surface 7 includes a first surface 12 and a second surface 13, which are L-shaped. Multiple stud mounting holes 9 are provided on both surfaces, arranged with gaps between them. The stern door position 11 of the unmanned surface vessel 10 includes an outer surface 14 and an inner surface 15, which are L-shaped.

[0020] The L-shaped surface 7 and the anti-collision surface 8 of the fender body 1 are an integral structure. The fender body 1 is integrally formed from rubber material, resulting in a simple manufacturing process and low cost.

[0021] Studs 6, corresponding to the number and position of the stud mounting holes 9 on the first surface 12, are welded to the outer side 14 of the stern door position 11. Similarly, studs 6, corresponding to the number and position of the stud mounting holes 9 on the first surface 12, are welded to the inner side 15 of the stern door position 11. In this structure, the number and position of the studs are set according to the number and position of the stud mounting holes 9 on the corresponding fender body, ensuring that each stud mounting hole 9 has a stud 6 passing through it for reliable fixation during fender body installation.

[0022] When the fender body 1 is installed at the stern door position 11, the first surface 12 of the L-shaped surface 7 fits against the inner surface 15 of the stern door position 11, each stud 6 passes through the corresponding stud mounting hole 9, and a nut 5 is screwed onto the outer end of each stud mounting hole 9. When the fender body 1 is installed at the stern door position 11, the second surface 13 of the L-shaped surface 7 fits against the outer surface 14 of the stern door position 11, each stud 6 passes through the corresponding stud mounting hole 9, and a nut 5 is screwed onto the outer end of each stud mounting hole 9. In this structure, when the fender body 1 is installed at the stern door position 11, the first surface 12 of the L-shaped surface 7 fits against the inner surface 15 of the stern door position 11, and the second surface 13 of the L-shaped surface 7 fits against the outer surface 14 of the stern door position 11, ensuring a reliable fit and fixation by screwing the studs 6 onto the nut 5.

[0023] When the fender body 1 is installed at the stern door position 11, a pressure plate 3 is provided between the first surface 12 of the L-shaped surface 7 and the nut 5, and each stud 6 passes through the corresponding through hole on the pressure plate 3. In the above structure, the pressure plate presses against the corresponding position of the fender body to prevent it from tilting up, and ensures that it fits as closely as possible with the mounting surfaces (outer side 14 and inner side 15) of the stern door position 11 to ensure the installation effect.

[0024] The diameter of the opening 4 is larger than the diameter of the stud mounting hole 9. In the above structure, the size of the opening 4 is slightly larger than the size of the stud 6, and the redundant size facilitates the installation of the nut 5 and the washer 2.

[0025] The fender structure of this utility model is constructed with a fender body 1 made of rubber material, integrally molded, and hollow in the middle. The fender body 1 is elongated, with an L-shaped surface 7, a collision-resistant surface 8, and nuts 5. The L-shaped surface 7 is used to attach and connect to the stern door 11 of the unmanned surface vessel 10, while the collision-resistant surface 8 faces outwards, providing collision protection. Studs are fixedly installed at the stern door 11 of the unmanned surface vessel 10. Stud mounting holes 9 are provided on the L-shaped surface 7.
