The embodiment of the invention discloses a hull underwater maintenance waterproof device. The device comprises a waterproof cover, an annular frame is fixedly arranged at the top of the waterproof cover, a supporting plate is fixedly arranged on an inner side of the top of the waterproof cover, a screw rod is movably arranged at the bottom of the supporting plate, a sliding plate is arranged at the bottom of the screw rod, the sliding plate is slidably connected with the waterproof cover, and a connecting ring is arranged in the center of the sliding plate. In the invention, a water suction pump pumps water in the waterproof cover through an L-shaped water suction pipe; the water is discharged through a drain pipe; when water in the waterproof cover is pumped out, the waterproof cover isin a negative-pressure state; and two clamping plates are stirred, the sliding plate is not limited, under the action of negative pressure, a maintenance tool is driven to move upwards, in an upward moving process, due to a fact that the two screw rods are both in threaded connection with the sliding plate, the maintenance tool can be effectively kept to ascend stably at a constant speed, the waterproof device effectively isolates water, a hull is drilled or cut under the action of negative pressure, use is convenient, and a maintenance speed of the hull is increased.

    本发明实施例公开了一种船体水下维修隔水装置,包括隔水罩,所述隔水罩的顶部固定设有环架,所述隔水罩的顶部内侧固定设有支板,所述支板的底部活动设有螺杆,所述螺杆的底部设有滑板,所述滑板与隔水罩滑动连接,所述滑板的中心处设有连接环。本发明的抽水泵通过L型抽水管抽取隔水罩内部的水体,并通过排水管排出,隔水罩内部水体抽完时为负压状态,拨动两个卡板,滑板不受限制,在负压的作用下,带动维修工具上移,上移过程中,由于两个螺杆均与滑板螺纹连接,可有效地保持维修工具匀速且平稳的上升,该隔水装置有效隔水,且利用负压作用钻孔或切割船体,便于使用且提高了船体的维修速度。
