SYNCHRONOUS PULLING UP FLOODGATE

摘要

PURPOSE: A synchronous system lifting watertight door for a breakwater is provided to prevent a watertight door from being damaged by transferring same rotatory force to both sides of the watertight door to stably lift the watertight door. CONSTITUTION: A synchronous system lifting watertight door in a breakwater comprises a rotary screw bar(30), a screw cap(21), a bevel gear(33), a horizontal shaft(40), and a passage cover(20-1). The rotary screw bar is installed in a vertical direction on both sides of a watertight door(20), and rotates by being hung on an upper center part of a watertight door frame(10). The screw cap covers the rotary screw bar in the inside of the watertight door, and lifts the watertight door by the rotation of the rotary screw bar. The bevel gear is installed on the rotary screw bar, and vertically moves by the rotation of the rotary screw bar. The horizontal shaft is fixed in the upper part of the watertight door. The passage cover is installed on the upper part of the watertight door, and covers the upper part of a watertight door passage(11).
