Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to an automatic mooring device for ships at shore, which aims to improve the safety and efficiency of ship mooring at shore. Background Art

[0002] Ships, also known as boats, are a general term for various types of vessels. A ship is a means of transport that can navigate or anchor in water for transportation or operations. It possesses varying technical performance, equipment, and structural types depending on its intended use. A ship is a man-made vehicle that primarily operates in water. Civilian vessels are generally called ships, military vessels are called warships, and small vessels are called boats or boats. Collectively, they are referred to as vessels or boats. The interior of a ship primarily consists of a container, support structures, and drainage systems, along with a propulsion system that utilizes external or self-generated energy. Its exterior generally features a streamlined envelope that helps overcome fluid resistance. Materials have evolved with technological advancements, from early natural materials such as wood, bamboo, and hemp to more modern materials such as steel, aluminum, fiberglass, acrylic, and various composite materials. Ships play a vital role in national defense, the national economy, and marine development. They are used not only for transporting people and cargo but also for a wide range of applications, including marine exploration, scientific research, and fisheries.

[0003] When a ship docks, it needs to be moored. This process typically involves an operator standing on deck, wrapping a rope around a bollard, and tightening the rope to prevent it from slipping. This manual mooring method is inefficient and carries safety risks, especially in inclement weather or at night, where manual operation is difficult and prone to accidents. Therefore, the development of an automated mooring device is crucial. Utility Model Content

[0004] In view of the existing deficiencies, the utility model provides an automatic mooring device for ships when docking, which can automatically connect to the mooring bollards on the dock during the ship docking process and quickly complete the mooring operation, thereby improving the efficiency and safety of the mooring operation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The camming member is a pair of camming members, each of which is connected to the frame by a chain, and the camming member is engaged with the frame by a chain. The camming member is engaged with the frame by a chain. The chain is connected to the frame by a chain. When the camming member is engaged with the frame, the chain is engaged with the frame by a chain. When the camming member is engaged with the frame, the chain is engaged with the frame by a chain. When the camming member is engaged with the frame, the chain is engaged with the frame by a chain. When the camming member is engaged with the frame, the chain is engaged with the frame by a chain. When the camming member is engaged with the frame, the chain is engaged with the frame

[0007] Furthermore, a lower fixing frame is fixed to the lower side of the upper fixing frame, a damping cylinder is fixed to the inner side of the lower fixing frame, and the interior of the damping cylinder is filled with a damping liquid medium, the lower end of the rotating shaft passes through the lower fixing plate and extends into the damping liquid medium inside the damping cylinder, and a plurality of groups of blades are evenly fixed on the annular surface of the lower section of the rotating shaft.

[0008] Furthermore, the outer end of the support arm is inserted through the connecting frame and is slidably connected, the inner end of the connecting support rod is inserted through the connecting frame and is slidably connected, and a limit block piece is fixed on the end surface of the connecting support rod and the support arm located in the connecting frame, and a first buffer spring is provided on the connecting support rod in the area between the connecting frame and the limit block piece, and a second buffer spring is provided on the support arm in the area between the connecting frame and the limit block piece.

[0009] Furthermore, a layer of wear-resistant lining is fixed on the inner wall of the hook groove, and the width of the wear-resistant lining is greater than the thickness of the mooring hook plate.

[0010] Furthermore, anti-slip lines are engraved on the inner side of the wear-resistant lining.

[0011] Furthermore, the limit assembly includes a limit baffle, a holder, a pin and a return spring. The holder is configured as an L-shaped structure and is fixed at the opening edge of the hook groove. A limit baffle is provided on the inner side of the holder. The limit baffle is rotatably connected to the holder through a pin. A return spring is sleeved on the annular surface of the pin in the area below the holder.

[0012] Furthermore, the limit baffle is parallel to the outer end surface of the mooring hook in an initial state, and the limit baffle can rotate within a range of 90 degrees counterclockwise.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Through mechanical drive and automated design, the utility model can automatically connect the ship to the mooring bollard when docking, and can quickly and accurately complete the ship's mooring operation, greatly improving mooring efficiency and shortening the time for ships to dock and leave the shore. In addition, automated operation reduces human participation, greatly reduces the burden on operators, improves work efficiency, and reduces the risk of accidents when operating in bad weather or at night.

[0015] 2. The damping cylinder in this utility model is used to contain a damping liquid medium. This medium is typically a liquid with high viscosity or special rheological properties, which can produce a significant damping effect when subjected to shear forces. As the shaft rotates, the blades cut the damping liquid medium, generating a damping force. This force slows the shaft's rotational speed, thereby acting as a buffer, helping to reduce the impact and vibration generated by the device during the mooring process. The damping and buffering design effectively absorbs impact energy, reduces the impact on the ship and dock during mooring, and protects the safety of the ship and dock facilities.

[0016] 3. The support arm and the connecting rod in the utility model are slidably connected to the connecting frame, which can perform corresponding telescopic movement during the mooring process of the device, reducing the generation of internal stress. At the same time, the first buffer spring and the second buffer spring can absorb and buffer the impact and vibration generated by the support arm and the connecting rod during the movement, protecting the device from damage.

[0017] 4. The present invention is capable of limiting the position of the mooring hook plate when the hook groove is connected to the mooring post by providing a limiting component, thereby preventing the mooring post from falling out of the hook groove opening. When the mooring hook plate is connected to the mooring post, the mooring post pushes the limiting baffle to rotate, causing it to temporarily leave the opening of the hook groove, thereby allowing the mooring hook plate to be smoothly clamped onto the mooring post through the hook groove. After the mooring hook plate is connected to the mooring post, the limiting baffle will automatically rotate back to its original position under the torsional force of the reset spring, blocking the opening of the hook groove and preventing the mooring post from falling out. In addition, when the ship needs to leave the mooring state, the limiting baffle can be pulled upward so that its lower end surface is higher than the upper surface of the mooring hook plate, and then the limiting baffle can be rotated ninety degrees clockwise so that the hook groove opening contacts the locked state, and then the mooring hook plate can be removed from the mooring post.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example:

[0028] like Figures 1 to 7As shown, an automatic mooring device for ships docking includes a base 1 and an upper fixing frame 4. The upper fixing frame 4 is welded to the upper side of the right end surface of the base 1. A driving motor 5 is installed on the left side of the top of the upper fixing frame 4. A driving shaft 12 is provided on the left side of the interior of the upper fixing frame 4, and the upper end of the driving shaft 12 is fixedly connected to the output end of the driving motor 5. Two sets of driving gears 13 are installed on the ring surface of the driving shaft 12. A rotating shaft 14 is vertically provided inside the upper fixing frame 4. A rotatable movable ring sleeve 10 is provided on the rotating shaft 14 in the inner area of ​​the upper fixing frame 4. A bearing 15 is installed at the connection between the movable ring sleeve 10 and the rotating shaft 14. A rotating ring sleeve 10 is fixed on both the upper and lower sides of the ring surface. The movable ring gear 11 and the driven ring gear 11 are meshed and driven by the driving gear 13. A support arm 6 is welded on the annular surface of the movable ring sleeve 10. The outer end of the support arm 6 is provided with a connecting frame 7 with a mesh structure. The outer end of the connecting frame 7 is connected to a connecting support rod 8. The outer end of the connecting support rod 8 is fixed with a mooring hook plate 9. The mooring hook plate 9 is provided with an arc-shaped hook groove 22 inside. Two groups of limit assemblies 20 are symmetrically provided at the opening of the inner wall of the hook groove 22. This design solves the problem that the existing ship mooring method mainly relies on manual operation, which is not only inefficient, but also has certain safety risks. Especially in bad weather or night operations, manual operation becomes more difficult and easily leads to accidents.

[0029] In this embodiment, a lower fixing frame 3 is fixed to the lower side of the upper fixing frame 4, and a damping cylinder 2 is fixed to the inner side of the lower fixing frame 3. The interior of the damping cylinder 2 is filled with a damping liquid medium. The lower end of the rotating shaft 14 passes through the lower fixing plate and extends into the damping liquid medium inside the damping cylinder 2. A plurality of groups of blades 16 are evenly fixed to the annular surface of the lower section of the rotating shaft 14. The damping cylinder 2 is used to accommodate the damping liquid medium. The damping liquid medium is generally a liquid with high viscosity or special rheological properties, which can produce a significant damping effect when subjected to shear force. When the rotating shaft 14 rotates, the blades 16 cut the damping liquid medium, generating a damping force. This force will hinder the rotation speed of the rotating shaft 14, thereby acting as a buffer, helping to reduce the impact and vibration generated by the device during the mooring process.

[0030] In this embodiment, the outer end of the support arm 6 is inserted through the connecting frame 7 and is slidably connected thereto. The inner end of the connecting rod 8 is inserted through the connecting frame 7 and is slidably connected thereto. A stopper 18 is fixedly provided on the end surfaces of the connecting rod 8 and the support arm 6 located within the connecting frame 7. A first buffer spring 17 is provided in a region of the connecting rod 8 between the connecting frame 7 and the stopper 18. A second buffer spring 19 is provided in a region of the support arm 6 between the connecting frame 7 and the stopper 18. The sliding connection between the support arm 6 and the connecting rod 8 and the connecting frame 7 enables corresponding telescopic movement during the mooring process, reducing the generation of internal stress. Furthermore, the first buffer spring 17 and the second buffer spring 19 absorb and buffer the impact and vibration generated by the support arm 6 and the connecting rod 8 during movement, protecting the device from damage.

[0031] In this embodiment, a wear-resistant lining 21 is fixedly mounted on the inner wall of the hook groove 22. The width of the wear-resistant lining 21 is greater than the thickness of the mooring hook plate 9. The wear-resistant lining 21 increases the strength and wear resistance of the inner wall of the hook groove 22. The wear-resistant lining 21 prevents the inner wall of the hook groove 22 from directly contacting the mooring post, thereby reducing wear on the inner wall of the hook groove 22.

[0032] In this embodiment, anti-skid patterns are engraved on the inner side of the wear-resistant lining 21. The function of the anti-skid patterns is to increase the friction between the wear-resistant lining 21 and the bollard, thereby improving the stability of the connection.

[0033] In this embodiment, the limiting assembly 20 includes a limiting baffle 201, a holder 202, a pin 203, and a return spring 204. The holder 202 is configured as an L-shaped structure and is fixedly mounted at the opening edge of the hook groove 22. The limiting baffle 201 is provided inside the holder 202. The limiting baffle 201 is rotatably connected to the holder 202 via the pin 203. The return spring 204 is sleeved on the annular surface of the pin 203 in the area below the holder 202. The upper end of the return spring 204 is fixedly connected to the holder 202, and the lower end is fixedly connected to the pin 203. The limiting assembly 20 can limit the mooring hook 9 when the hook groove 22 is connected to the bollard, preventing the bollard from falling out of the opening of the hook groove 22. When the mooring hook 9 is connected to the mooring post, the mooring post pushes the limit baffle 201 to rotate, temporarily leaving the opening of the hook groove 22, so that the mooring hook 9 can be smoothly clamped on the mooring post through the hook groove 22. After the mooring hook 9 is connected to the mooring post, the limit baffle 201 will automatically rotate back to its original position under the torsional force of the return spring 204, blocking the opening of the hook groove 22 and preventing the mooring post from falling out.

[0034] In addition, when the ship needs to leave the mooring state, the limit baffle 201 can be pulled upward so that its lower end surface is higher than the upper surface of the mooring hook plate 9, and then the limit baffle 201 can be rotated ninety degrees clockwise so that the hook groove 22 opens and contacts the locked state, and then the mooring hook plate 9 can be removed from the mooring column.

[0035] In this embodiment, the stopper 201 is initially parallel to the outer end surface of the mooring hook 9 and can rotate counterclockwise within a range of 90 degrees. This design ensures that when the mooring hook 9 is connected to the bollard, the bollard can smoothly push the stopper 201 to rotate and enter the hook groove 22 without excessive resistance. At the same time, the stopper 201 can firmly block the opening of the hook groove 22 after rotation, preventing the mooring hook 9 from falling off the bollard.

[0036] The working principle of the automatic mooring device for ships at dock is as follows: when a ship is mooring at dock, the operator first starts the drive motor 5, which drives the drive shaft 12 to rotate, and at the same time drives the two sets of driving gears 13 thereon to rotate ninety degrees clockwise. Since the driven ring gear 11 on the annular surface of the movable ring sleeve 10 is engaged and driven by the driving gear 13, the driven ring gear 11 and the movable ring sleeve 10 rotate along with the driving gear 13, and rotate ninety degrees counterclockwise, so that the support arm 6 and the mooring hook plate 9 rotate to a position perpendicular to the surface of the base 1;

[0037] Then, during the docking process, the mooring hook plate 9 gradually approaches the mooring post and is finally clamped onto the mooring post through the hook groove 22, completing the mooring. In the process of the mooring hook plate 9 connecting to the mooring post, the two sets of limit assemblies 20 symmetrically arranged at the opening of the inner wall of the hook groove 22 play a key role. When the mooring hook plate 9 approaches the mooring post, the mooring post pushes the limit baffle 201 to rotate, temporarily leaving the opening of the hook groove 22. In this way, the mooring hook plate 9 can be smoothly clamped onto the mooring post through the hook groove 22. Once the mooring hook plate 9 is connected to the mooring post, the limit baffle 201 will automatically rotate back to its original position under the action of the reset spring 204, blocking the opening of the hook groove 22 and preventing the mooring post from falling out. At the same time, the support arm 6 and the connecting support rod 8 are slidably connected to the connecting frame 7, and a first buffer spring 17 and a second buffer spring 19 are provided at the connection. The first buffer spring 17 and the second buffer spring 19 can absorb and buffer the impact and vibration generated by the support arm 6 and the connecting support rod 8 during the movement, thereby protecting the device from damage. In addition, the device is also provided with a damping and buffering mechanism to reduce impact and vibration. The lower end of the rotating shaft 14 passes through the lower fixed plate and extends into the damping liquid medium inside the damping cylinder 2, and a plurality of groups of blades 16 are evenly fixed on the annular surface of the lower section of the rotating shaft 14. When the rotating shaft 14 rotates, the blades 16 will cut the damping liquid medium and generate a damping force. This force will hinder the rotation speed of the rotating shaft 14, thereby playing a buffering role;

[0038] When the vessel needs to detach from the mooring state, the operator can pull the limit stopper 201 upward so that its lower end surface is higher than the upper surface of the mooring hook plate 9, and then rotate the limit stopper 201 90 degrees clockwise to open the hook groove 22 and release the lock state. After that, the mooring hook plate 9 can be removed from the mooring post to complete the detachment operation.

[0039] In summary, the ship's automatic mooring device is mechanically driven and automated. The device can automatically connect the ship to the mooring post when docking, and can complete the ship's mooring operation quickly and accurately. It not only improves the mooring efficiency, but also reduces the risk and difficulty of manual operation, and is safer and more reliable, especially in bad weather or at night.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
