Abstract
[Objective]To address the key issues of low efficiency,poor stability,and high labor costs in marine lightweight instrument recovery operations,herein we study an improved solution based on a long carbon rod gripping device and a winding anti-swing method.[Methods]The marine lightweight instrument recovery was decomposed into gripping and anti-swing problems.A long carbon rod with a shackle was designed as the gripping device to extend the gripping distance.Also,carbon rod's parameters(length:2.1 m,diameter:25 mm)were optimized using the cantilever beam deflection formula.Next,the stress-distribution Gaussian model was employed to simulate stress concentration in the shackle's pin hole,thus ensuring a safe and reliable gripping device.Combined with a winding friction model,a winding anti-swing scheme was proposed.Consequently,the human force amplification was achieved;personnel requirements were reduced;as well as the recovery success rate and the safety were improved.Finally,the adaptability of the method under different sea conditions was validated through dynamic response analyses.[Results]Real-ship tests during a China-India joint voyage demonstrated that,under sea state4,a single person could stably recover a 120 kg instrument,with a safety margin of 82%,a single recovery time of no more than 108 s,and a swing angle suppression rate of 68%.[Conclusion]This rapid recovery and anti-swing method for marine lightweight instruments requires simple equipment,exhibits high stability and safety,effectively reduces labor costs,and enhances recovery efficiencies.关键词
