本发明公开一种海底电缆抢修打捞回放过程试验装置及方法,所述装置包括六自由度平台,手动吊葫芦一端与六自由度平台连接,下水桥设在六自由度平台边缘,手动吊葫芦连接的缆绳沿下水桥表面向地面方向延伸,缆绳延伸至地面的一端与海缆一端连接,海缆另一端由地面固定装置固定;力传感器、应变片设置在海缆的表面上,本发明在不同的船体速度与海缆起吊或下放速度比的情况下进行试验,得到海缆打捞回放过程中海缆张力、应力及曲率数据;本发明可确定不同工况下,海缆打捞回放时可使用的船体速度与起吊或下放速度比,避免出现海缆打捞或回放过程中因采用了不恰当的船体速度与起吊或下放速度比导致海缆张力或应力或曲率过大,以致海缆被破坏的情形。
The invention discloses a submarine cable first-aid repair, salvage and playback process test device and method, and the device comprises a six-degree-of-freedom platform, one end of a manual hoist is connected with the six-degree-of-freedom platform, a lower water bridge is arranged at the edge of the six-degree-of-freedom platform, and a cable connected with the manual hoist extends towards the ground along the surface of the lower water bridge. One end of the cable extending to the ground is connected with one end of a submarine cable, and the other end of the submarine cable is fixed by a ground fixing device; according to the submarine cable tension, stress and curvature testing device, testing is carried out under the condition of different ship body speeds and submarine cable lifting or lowering speed ratios, and submarine cable tension, stress and curvature data in the submarine cable salvage and replay process are obtained; according to the method, the ratio of the ship body speed to the hoisting or lowering speed which can be used when the submarine cable is salvaged and put back under different working conditions can be determined, and the situation that the submarine cable is damaged due to the fact that the tension or stress or curvature of the submarine cable is too large due to the fact that the improper ratio of the ship body speed to the hoisting or lowering speed is adopted in the submarine cable salvage or put back process is avoided.
