The invention relates to the technical field of submarine cable laying, in particular to a rear flushing and burying workboat. The rear flushing and burying workboat is provided with a navigation system capable of communicating with a satellite and comprises a boat body, signal generation equipment, signal induction alarm equipment, submarine cable positioning equipment and flushing and burying equipment, the signal generation equipment and the submarine cable positioning equipment are both stored on the boat body, and the signal induction alarm equipment and the flushing and burying equipment are both installed on the boat body. When the rear flushing and burying workboat is used, the rear flushing and burying workboat advances along a submarine cable direct laying line through the navigation system, the signal generation equipment is connected into the submarine cable, the submarine cable continuously transmits and diffuses signals to the surrounding space, the signal induction alarm equipment can detect the intensity of the space signals in real time, and when the boat body is located over the submarine cable, the signal induction alarm equipment gives an alarm. When the submarine cable is buried, the signal induction alarm device gives the strongest alarm, at the moment, the submarine cable positioning device records the position of the ship body, the buried device carries out buried operation on the recorded position, and then post-buried burying of the submarine cable at the position can be completed.
本发明涉及海缆敷设技术领域,尤其涉及一种后冲埋施工船。该后冲埋施工船,配备有能够与卫星通信的导航系统,包括船体、信号生成设备、信号感应报警设备、海缆定位设备和冲埋设备,信号生成设备和海缆定位设备均存放在船体上,信号感应报警设备和冲埋设备均安装在船体上。该后冲埋施工船使用时,通过导航系统沿海缆直敷线路行进,并通过将信号生成设备接入海缆,使海缆向周围空间持续传播扩散信号,而信号感应报警设备则能够实时检测空间信号强弱,当船体位于海缆正上方时,信号感应报警设备发出的警报最强,此时通过海缆定位设备记录船体所在位置,并通过冲埋设备对该记录位置进行冲埋作业,即可完成对该位置海缆的后冲埋。
