Claims (1)

[Scope of utility model registration request] An upper door and a lower door are installed inside a gate-shaped frame so that they can be raised and lowered, and a main operating device is installed on the top of the frame.
A door lifting rod is attached to the main operating machine so that it can be raised and lowered, the lower end of the door lifting rod is connected to the hanging bracket of the upper door, and a rotating rod is placed in parallel at a distance from the door lifting rod. The upper end of the rotary rod is passed through an auxiliary operating device consisting of a rotary boss that is installed on the upper surface of the frame and transmits only rotation to the rotary rod, and a boss with a handle that has a spring that elastically rotates the rotary boss, Further, a horizontal rotating arm is attached to the lower end of the rotating rod, and the horizontal rotating arm is elastically and detachably engaged with a groove provided vertically at intervals on at least one side surface of the lower door. A water level adjustable water gate with a door engagement/disengagement device.
