Design and Performance Analysis of ROV Suitable for Patrol Inspection of Chain System of Navigation-aids
At present,the inspection of marine navigation-aids is only limited to external inspection,the underwater state of light buoy chain can not be accurately grasped,and the phenomenon of light-buoy displacement and drift often occurs.In view of this phenomenon,In order to grasp the underwater state of light buoy chain,a design scheme of remotely operated vehicle(ROV)system suitable for daily navigational aid inspection was proposed,which is mainly composed of ROV body,umbilical cable,winding reel and water surface control system.It aims to accurately grasp the underwater situation of light buoy chain,clean up the marine biological fouling on the light buoy,recover and salvage modulators and batteries that have fallen into the sea as far as possible,position-aided salvage of the anchorage stones to clear waterways and save resources.The design scheme of each module and control system of ROV body was introduced.The overall model of ROV was established to carry out hydrody-namic analysis and simulate the resistance of the ROV system in the design direction and speed,providing a basis for the selec-tion of propeller.
