A ship positioning device

Abstract

This utility model discloses a ship positioning device, relating to the field of ship positioning technology. It includes a fixed base, with a column welded to the top of the fixed base. The top of the column has an installation groove, and an electrically controlled telescopic rod is bolted to the bottom of the installation groove. A movable column is located at the top of the column, with a fixing ring installed on its outer side. A top plate is located at the top of the movable column. This utility model utilizes the presence of a fixing block to allow a hydraulic mechanical gripper to be held securely to its outer side, achieving a stable rigid connection. By utilizing the elasticity of a spring block and the extension / retraction of the electrically controlled telescopic rod, the height of the mounting plate can be adjusted. This allows the device to adapt to changes in water level, enabling the ship to freely rise and fall with the waves within a certain range after connection. Simultaneously, the rigid connection effectively resists continuous forces such as wind and current in the horizontal direction, thus firmly fixing the ship in the target position.

Description

Technical Field

[0001] This utility model relates to the field of ship positioning technology, specifically a ship positioning device. Background Technology

[0002] When ships are berthing, anchoring, or performing specific operations, they need to maintain a precise position. Currently, this mainly relies on anchoring systems and dynamic positioning (DP) systems, but these systems have significant drawbacks. First, the water level is not stable during berthing, causing the ship to rise and fall. Second, existing anchoring systems lack corresponding adaptive structures, resulting in unstable berthing and positioning, which is inconvenient. Third, existing dynamic positioning (DP) systems are expensive and suitable for large ships, but not for small and medium-sized ships. Therefore, this project was developed to solve this problem and design a ship positioning device. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Example 1: Please refer to Figure 1-4 A ship positioning device includes a fixed base 2, a column 1 welded to the top of the fixed base 2, and a mounting groove 16 formed at the top of the column 1. An electrically controlled telescopic rod 17 is bolted to the bottom of the mounting groove 16. A movable column 3 is provided at the top of the column 1, and a fixing ring 14 is installed on the outer side of the movable column 3. A top plate 13 is provided at the top of the movable column 3, and multiple vertical rods 5 are installed at equal angles at the bottom of the top plate 13. The bottom end of each vertical rod 5 passes through the bottom end of the fixing ring 14 and is connected to a clamping plate 15. A spring is sleeved on the outer side of each vertical rod 5. The top of the spring block 4 and the top plate 13 are mounted with a mounting plate 6 via a bearing. Fixing rods 12 are mounted around the outer perimeter of the mounting plate 6. A magnetic block 7 is mounted on the top of the fixing rod 12. A fixing block 19 is welded to the center of the top of the mounting plate 6. A slot 18 is provided around the outer perimeter of the fixing block 19. A ship connector 10 is provided on the top of the fixing block 19. A hydraulic mechanical gripper 8 is mounted on the bottom of the ship connector 10. A mounting ring 9 is sleeved on the outer perimeter of the ship connector 10. A magnetic rod 11 is mounted around the outer perimeter of the mounting ring 9. Both the magnetic rod 11 and the fixing rod 12 are L-shaped, and the magnetic rod 11 is positioned directly above the fixing rod 12; The bottom end of the magnetic rod 11 is in contact with the top end of the magnetic block 7, and the magnetic rod 11 and the fixed rod 12 have opposite magnetic properties; The top end of the spring block 4 is in contact with the bottom end of the fixing ring 14, and the bottom end of the spring block 4 is in contact with the top end of the clamping plate 15. The bottom end of the movable column 3 passes through the top of the column 1 and extends into the interior of the column 1. The bottom end of the movable column 3 is connected to the top of the electrically controlled telescopic rod 17 by bolts. The outer side of the movable column 3 is in contact with the inner wall of the mounting groove 16. The fixed base 2 is fixed to the bottom of the water by anchor chains, and both the fixed base 2 and the column 1 are made of high-strength alloy metal materials; The diameter of the fixed block 19 is smaller than the opening range of the hydraulic mechanical gripper 8, and the internal dimensions of the slot 18 are larger than the dimensions of the claw rod of the fixed block 19. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in the process of using this device, firstly, the device is fixedly installed on the seabed by the presence of a fixed base 2. During the docking of the ship, the ship connector 10 is released to the seabed. Utilizing the presence of the hydraulic mechanical gripper 8 and the fixed block 19, during the expansion and contraction of the hydraulic mechanical gripper 8, its claw rod is locked inside the slot 18, connecting the fixed block 19 and the hydraulic mechanical gripper 8 to achieve the positioning effect. During this process, due to the presence of the magnetic block 7 and the magnetic rod 11, the magnetic relationship between the two allows the magnetic rod 11 to be attracted during the sinking of the ship connector 10. This enables the hydraulic mechanical gripper 8 to quickly move above the fixed block 19, achieving a good rapid positioning effect and ensuring that the hydraulic mechanical gripper 8 can stably grip the outside of the fixed block 19. Secondly, this device also... With the presence of the mounting plate 6, which is mounted on top of the top plate 13 via bearings, the rotatable mounting plate 6 allows for faster contact between the magnetic block 7 and the magnetic rod 11. During positioning, the device features a vertical rod 5. As the water level changes, the device's height can be adjusted by extending and retracting the electrically controlled telescopic rod 17, facilitating adaptation to significant water level variations. Furthermore, the presence of a spring block 4 allows the mounting plate 6 to adjust its height slightly with minor water level changes, enhancing its flexibility and ensuring stable berthing of the vessel during transport. This makes the device convenient and practical.
