Description

Technical Field

[0001] This utility model relates to the field of ship collision avoidance technology, and in particular to an adjustable ship collision avoidance device. Background Technology

[0002] Ship collision avoidance is a crucial aspect of shipping safety, directly impacting the safety of crew and cargo. In busy waterways, the risk of collisions between vessels is ever-present, especially near narrow channels, ports, or bridges. To avoid such dangerous situations, physical collision avoidance measures have become indispensable. Traditional physical collision avoidance methods mainly involve installing barriers such as crash barriers and guardrails. These barriers are typically installed at key locations in waterways, such as bridge piers and dock edges, to block or mitigate the impact of out-of-control vessels. These collision avoidance facilities are simple and practical in design, providing the first line of defense in the event of an accident and effectively reducing damage caused by a collision. However, with the development of the shipping industry and the increase in ship tonnage, the requirements for collision avoidance facilities are also increasing, necessitating more intelligent, flexible, and adaptable collision avoidance systems to cope with various complex aquatic environments.

[0003] Existing ship collision avoidance systems generally employ a fixed-height design. While this design provides some collision protection, it is difficult to adjust in real time according to water level changes. In natural water bodies such as rivers and lakes, water levels are frequently affected by various factors such as seasons, rainfall, and tides. When water levels rise, even well-designed collision avoidance facilities may become ineffective due to insufficient height; conversely, when water levels drop, excessively high collision avoidance facilities may become navigational obstacles, hindering the normal passage of ships.

[0004] Patent document CN113619749B discloses an adjustable ship collision avoidance device. This invention includes a collision avoidance backplate, with a fixing mechanism for securing it to the ship mounted on the top of one side of the backplate. A height adjustment mechanism for height adjustment is fixed to the other side of the backplate, and a quick-release mechanism for easy disassembly is mounted on one side of the height adjustment mechanism. Through its structural design, this invention allows for easier and more secure mounting to the ship without requiring holes in the ship, thus avoiding surface damage. The device allows for height adjustment of the shock-absorbing mechanism, making it suitable for various conditions. It also provides dual shock absorption, resulting in better overall shock absorption, less impact on the ship, and superior performance. Furthermore, damaged shock-absorbing mechanisms can be easily and quickly replaced, making operation convenient and efficient.

[0005] As in the prior art of the aforementioned patent, the anti-collision device uses a screw to adjust the height of the movable mounting platform, thereby further adjusting the height of the shock-absorbing and buffering mechanism. However, since the ship moves in the lake for a long time, the screw is submerged in water for a long time, which may cause corrosion. In addition, some aquatic plants or aquatic organisms may adhere to the surface of the screw, which may affect the normal operation of the screw. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable ship collision avoidance device to address the aforementioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable ship anti-collision device, comprising two upper fixed blocks, two lower fixed blocks, and two support plates. Two fixing cables are fixedly installed between the two upper fixed blocks and the two lower fixed blocks respectively. An anti-collision component is provided between the two fixing cables. The anti-collision component includes two pull rings and an inner anti-collision plate. The two pull rings are fixedly installed on the top of the inner anti-collision plate. The two fixing cables are slidably connected to the inner anti-collision plate. Two connecting cables are fixedly installed on the two pull rings. The two connecting cables are fixedly connected. A winding roller is rotatably installed between the two support plates. A pull cable is wound on the winding roller. One end of the pull cable is fixedly connected to one end of the two connecting cables.

[0008] As a further description of the above technical solution: the anti-collision assembly also includes multiple buffer units and an outer anti-collision plate. The multiple buffer units are disposed between the outer anti-collision plate and the inner anti-collision plate. Each buffer unit includes two fixed plates, and a rotating shaft is rotatably installed between the two fixed plates. A movable ring is sleeved on the rotating shaft. The movable ring is slidably and rotatably connected to the rotating shaft. A damping rod is fixedly installed on the movable ring. The other end of the damping rod is fixedly connected to the outer anti-collision plate. Multiple buffer pads are fixedly installed on the side wall of the outer anti-collision plate.

[0009] As a further description of the above technical solution: two springs are sleeved on the rotating shaft, and the two springs are respectively arranged on both sides of the movable ring.

[0010] As a further description of the above technical solution: a self-locking motor is fixedly installed on the side wall of one of the support plates, and the output end of the self-locking motor is connected to the winding roller drive.

[0011] As a further description of the above technical solution: the inner anti-collision plate has two through holes, the fixing cable passes through the through holes, and the diameter of the through holes is larger than the diameter of the fixing cable.

[0012] As a further description of the above technical solution: both the inner and outer anti-collision plates are provided with an air cushion layer at their bottom ends.

[0013] This invention provides an adjustable ship collision avoidance device. It offers the following advantages: The inner collision avoidance plate is fixed between two fixed cables. The through holes in the two fixed cables are larger than the connecting cables, allowing the inner collision avoidance plate to slide smoothly up and down on the two connecting cables without jamming. When the inner collision avoidance plate needs to be raised, a motor rotates a winding roller, which pulls the cable upwards. The cable then pulls the ring through the connecting cable, thus raising the inner collision avoidance plate. When the inner collision avoidance plate needs to be lowered, the winding roller rotates in the opposite direction, and the inner collision avoidance plate slides downwards along the fixed cables under gravity, achieving downward adjustment. Furthermore, the fixed cables are made of high-strength, corrosion-resistant organic compounds, preferably ultra-high molecular weight polyethylene, which prevents rust and avoids the problem of the inner collision avoidance plate being unable to slide on the fixed cables.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0015] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 An adjustable ship collision avoidance device includes two upper fixed blocks 4, two lower fixed blocks 5, and two support plates 1. Two fixing cables 6 are fixedly installed between the two upper fixed blocks 4 and the lower fixed blocks 5 respectively. A collision avoidance assembly is provided between the two fixing cables 6. The collision avoidance assembly includes two pull rings 8 and an inner collision avoidance plate 7. The two pull rings 8 are fixedly installed on the top of the inner collision avoidance plate 7. The two fixing cables 6 are slidably connected to the inner collision avoidance plate 7. Two connecting cables 9 are fixedly installed on the two pull rings 8 and are fixedly connected. A winding roller 2 is rotatably installed between the two support plates 1. A cable 10 is wound on the winding roller 2, and one end of the cable 10 is fixedly connected to one end of the two connecting cables 9. The inner collision avoidance plate 7 is fixed to the two supporting plates 1. Between the fixed cables 6, the through holes 19 are larger than the connecting cables 9, allowing the inner anti-collision plate 7 to slide smoothly up and down on the two connecting cables 9 without jamming. When the inner anti-collision plate 7 needs to be lifted, the motor rotates the take-up roller 2, which pulls the pull cable 10 upward. The pull cable 10 pulls the pull ring 8 through the connecting cable 9, thus pulling the inner anti-collision plate 7 upward. When the inner anti-collision plate 7 needs to be lowered, the take-up roller 2 is rotated in the opposite direction, and the inner anti-collision plate 7 slides downward along the fixed cables 6 under the action of gravity, achieving downward adjustment. Furthermore, the material of the fixed cables 6 is a high-strength, corrosion-resistant organic compound, preferably ultra-high molecular weight polyethylene, which can prevent rust and avoid the problem of the inner anti-collision plate 7 being unable to slide on the fixed cables 6.

[0025] As a preferred embodiment, the anti-collision assembly further includes multiple buffer units and an outer anti-collision plate 11. The multiple buffer units are disposed between the outer anti-collision plate 11 and the inner anti-collision plate 7. Each buffer unit includes two fixed plates 13, and a rotating shaft 14 is rotatably mounted between the two fixed plates 13. A movable ring 16 is sleeved on the rotating shaft 14. The movable ring 16 is slidably and rotatably connected to the rotating shaft 14. A damping rod 17 is fixedly mounted on the movable ring 16. The other end of the damping rod 17 is fixedly connected to the outer anti-collision plate 11. Multiple buffer pads 12 are fixedly mounted on the side wall of the outer anti-collision plate 11. The outer anti-collision plate 11 and the inner anti-collision plate 7 can form a double anti-collision structure. The damping rod 17 connected in the middle can effectively alleviate the vibration caused by the impact. The damping rod 17 is connected to the inner anti-collision plate 7 through the movable ring 16. The movable ring 16 can rotate on the rotating shaft 14 and slide left and right on the rotating shaft 14, which can adapt to the impact of the outer anti-collision plate 11 from different angles, thus increasing the anti-collision performance.

[0026] As a preferred technical solution in this embodiment, two springs 15 are sleeved on the rotating shaft 14, and the two springs 15 are respectively arranged on both sides of the movable ring 16; the springs 15 arranged on both sides of the movable ring 16 can play a buffering role.

[0027] As a preferred technical solution in this embodiment, a self-locking motor 3 is fixedly installed on the side wall of one of the support plates 1. The output end of the self-locking motor 3 is connected to the winding roller 2 in a transmission manner. The self-locking motor 3 is a prior art technology. Its function is to prevent external force from causing rotation of the output shaft when the motor is not running, thereby locking the winding roller 2.

[0028] As a preferred technical solution in this embodiment, the inner anti-collision plate 7 has two through holes 19, and the fixing cable 6 passes through the through holes 19. The diameter of the through holes 19 is larger than the diameter of the fixing cable 6; this prevents the fixing cable 6 and the through holes 19 from generating large frictional forces and avoids jamming.

[0029] As a preferred technical solution in this embodiment, both the inner anti-collision plate 7 and the outer anti-collision plate 11 are provided with an air cushion layer 18 at their bottom ends; the air cushion layer 18 enables the inner anti-collision plate 7 and the outer anti-collision plate 11 to float stably on the horizontal surface, thus stably achieving the anti-collision effect.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
