The invention discloses a recovery device for an underwater submarine pipe cable protection pad, which is characterized in that when a platform crane on a mother ship puts the recovery device into water, the position of the protection pad is positioned through a carried camera, a sonar device, a beacon and an illuminating lamp; the position of a lifting hook of the recovery device relative to a protection pad is accurately adjusted by controlling thrust of a propeller, so that a hook tip of the lifting hook of the recovery system is almost parallel to the bottom surface of the protection pad, and after a hook head of the lifting hook is close to the bottom of the protection pad, the position of the lifting hook is finely adjusted by analyzing data collected by a camera and a sensor to find an optimal lifting point; at the moment, the hydraulic push rod is controlled to drive the lifting hook to clamp the protection pad, and the distance between the protection pad and the hexagonal clamping mechanism is gradually reduced until the upper part of the protection pad is attached to a groove of the hexagonal clamping mechanism, so that the hook head, the protection pad and the clamping device are tightly attached, and the hook head is prevented from falling or deviating in the recovery and ascending process.
本发明公开了一种水下海底管缆保护垫的回收装置,当母船上的平台吊机将回收装置放入水下时,通过搭载的摄像机、声呐装置、信标以及照明灯,定位保护垫的位置;通过控制螺旋桨的推力精确调整回收装置吊钩相对于保护垫的位置,使回收系统的吊钩钩尖位置近乎与保护垫底面平行,吊钩的勾头靠近保护垫底部后,通过分析摄像头和传感器收集来的数据进行微调吊钩的位置找到最佳起吊点,此时控制液压推杆带动吊钩卡住保护垫,保护垫与六边形卡紧机构的距离逐渐缩小,直至保护垫上部位置与与六边形卡紧机构的凹槽贴合,使勾头、保护垫、卡紧装置三者紧密贴合,防止在回收上升过程中出现掉落或偏移。
