景洪升船机500吨级船舶实船试验船厢水面波动特性研究

升船机承船厢对接过程是升船机运行全过程中重要的一环,对接过程中船厢内的水面波动直接影响厢内船舶的安全停靠和水力式升船机同步轴工作条件。针对这一过程中厢内水面波动变化特性对升船机安全运行的影响,进行了在不同对接水位差启闭卧倒门和在不同航速进出船厢的500吨级船舶实船试验。重点探讨了对接水位差、船舶进出船厢航速对厢内水面波动特征值的影响,给出了船厢内波动振幅与水深和水位差的经验公式,分析其对船厢和船舶航行安全的影响。实船试验成果验证了景洪升船机500吨级船舶通航安全性。

Study on the fluctuation characteristics of water surface in the ship chamber of Jinghong ship lift 500 t class ship test

The docking process is an important part in the whole process of ship lift operation.The fluctuation of water surface in the ship chamber during docking directly affects the safe docking of the ship and the working conditions of the synchronous shaft of the hydraulic ship lift.Aiming at the influence of the fluctuation characteristics of the water surface inside the ship chamber on the safe operation of the ship lift during this process,the 500 t class ship prototype test of opening and closing the horizontal door at different docking water levels and the ship entering and leaving the tank at different speeds is carried out.The effects of the docking water level and the speed of the ship entering and leaving the chamber on the characteristic of the water surface fluctuations in the tank are mainly discussed.The empirical formulas for the amplitude of the fluctuations in the ship chamber and the difference in water depth and water level are given to analyze its impact on the safety of tank and ships.The test results verify the navigation safety of the 500 t class ship of Jinghong ship lift.
