The invention belongs to the technical field of ship repair, and discloses an underwater log replacement method and a plugging tool applied by the same, the method is used for replacing a log installed on a ship bottom outer plate, the log comprises a guide rod, a sea valve and a lifting driving piece, the guide rod can penetrate through the sea valve and penetrate out of a cabin from an opening formed in the ship bottom outer plate, and the lifting driving piece is arranged on the guide rod. The lifting driving piece is connected with the guide rod to drive the guide rod to ascend and descend, and when the log is replaced, the guide rod is firstly dismantled, the sea valve is closed, then the opening is blocked by using the blocking tool from the outside of the cabin, the part, except the guide rod, of the old log is dismantled in the cabin, a new log is installed, and finally the blocking tool is dismantled. According to the method for replacing the log underwater, the log can be replaced without the need for a ship to dock, and the cost for replacing the log is reduced.

    本发明属于船舶修理技术领域,公开了一种计程仪的水下更换方法及其应用的封堵工装,用于更换船底外板上安装的计程仪,计程仪包括导杆、通海阀和升降驱动件,导杆能够穿过通海阀并从船底外板上开设的开口穿出船舱,升降驱动件与导杆连接,以带动导杆升降,在更换计程仪时,先将导杆拆除并封闭通海阀,然后从舱外利用封堵工装封堵开口,再在舱内拆除旧的计程仪除导杆以外的部分并安装新的计程仪,最后拆除封堵工装。上述计程仪的水下更换方法无需船舶进坞即可实现计程仪的更换,降低了计程仪更换的成本。
