Structural Optimization And Analysis Of Fast Recovery Valve For Oil Storage On Sunken Ship

With the rapid development of my country’s shipping industry,maritime transportation has become increasingly busy,the number and density of maritime activities have continued to increase,and the navigation environment has become increasingly complex.When a shipwreck accident occurs,there is an urgent need to promptly and effectively recover the oil that has not leaked and remains in the sunken ship,so as to greatly reduce the risk of pollution to the marine environment from the oil spilled from the sunken ship,and quickly store oil on the sunken ship.The recycling problem has attracted more and more attention at the moment.The traditional recycling method is bulkier and more dependent on manpower,resulting in a high risk factor.In this context,in view of the pollution problem caused by the oil spill from the sunken ship to the marine environment,the design of a fast recovery valve for the sunken ship oil storage is of far-reaching significance.In this paper,for the purpose of rapid recovery of oil storage on sunken ships,a quick recovery valve for oil storage on sunken ships is designed in which the valve and quick coupling are connected.It mainly includes the main body of the fast recovery valve for oil storage on sunken ships and the quick connection with it.Two parts of the joint.Created a three-dimensional model of the main body of the sunken ship oil storage quick recovery valve body and the quick coupling connector,and simulated the strength and deformation of the designed parametric model of the valve main valve body and coupling quick coupling shell.The result cloud chart can be obtained.The maximum equivalent stress suffered by both is within the allowable stress value range of the material,and the maximum deformation also meets the design requirements.Taking the main valve body of the sunken ship oil storage quick recovery valve and the shell of the docking quick connector as the object,the topology optimization of the sunken ship oil storage quick recovery valve body is performed using ANSYS Workbench,and the material layout optimization of the valve main valve body is obtained.Under the condition of the test pressure of 1.5 MPa,the redundant structural dimensions of the main valve body and the butt quick coupling shell are used as design variables,and the multi-objective parameter optimization method is adopted to perform the main valve body and the butt quick coupling shell body.Optimized processing and obtained the optimal structural dimensions of the valve body and the docking quick coupling.The overall weight of the main valve body was reduced by 5.2%,and the overall weight of the docking quick coupling was reduced by 4.0%,which improved the overall main valve body and the docking quick coupling.The stress distribution improves the overall performance and economy of the designed main body of the sunken ship oil storage quick recovery valve and the docking quick connector.Through the Adams simulation software of kinematics,the breaking force of the quick-release structure device was simulated and analyzed.Based on the 3D model of the valve and the docking quick connector designed in this subject,the 3D printing technology was used to print and assemble the same structure and The prototype of the principle,research on the factors affecting the breaking force of the rapid detachment of the structure device,conduct corresponding experimental research,compare the simulation results and the experimental results,the two trends are consistent,and the ball and the sunken ship’s oil storage fast recovery valve cage are obtained.And the friction between the grooves of the detachment body and the stretching speed have no obvious influence on the breaking force.Therefore,the experimental downsizing of the prototype provides practical data reference significance for the future application of the prototype to the actual project.
