Description

Technical Field

[0001] The utility model relates to a port equipment test device, more specifically, to a ship motion simulation test device. Background Art

[0002] With the global development of logistics and trade and the continuous advancement of automatic control technology, the cable-free automatic mooring system is gradually replacing the traditional cable mooring method with its advantages of high efficiency, economy, safety and reliability.

[0003] Vacuum anchor is a kind of automatic mooring without cable. It uses hydraulic technology to use the suction force generated by vacuum suction cups to adsorb on the side of the ship, and adjusts the movement of the suction cups in XYZ degrees of freedom through the control system. It can quickly and firmly anchor the ship at the berth, generally completing the mooring operation within 10 to 20 seconds, and ensure that the ship is stably connected to the dock during the docking process, which improves the loading and unloading speed, shortens the docking time of the ship at the dock, speeds up the turnover of ships, and improves the utilization rate of the dock.

[0004] For safety and practicality reasons, vacuum anchors need to be tested in various sea conditions before they are put into actual use. At present, vacuum anchor products are directly installed at the dock for testing, which results in a long cycle, and if they need to be repaired, the cost is relatively high, and there are also certain safety risks. If a test device simulating ship movement can be designed, it can simulate the impact of ship movement on vacuum anchor operations in a convenient, economical, safe and reliable experimental environment, verify the functionality of the vacuum anchor, and ensure the safety and reliability of the operation process, which has important practical significance for the application of vacuum anchors in marine engineering.
