PURPOSE: A water gate which can open and close a door in a folding or rotating method is provided to improve the exterior of a water gate and to reduce construction costs. CONSTITUTION: A water gate controls the water amount using a gate(20). The gate comprises a first dividing member(22), a second dividing member(24), an actuator(40) and a second rotational axis(50). The first dividing member and the second dividing member are divided at least two parts in order to be folded to top and bottom side. The actuator has one end which is combined with a first rotational axis(30), and the other end which is combined in the second dividing member. The first rotational axis is installed on the top of a drain outlet(12). The second rotational axis is installed to be vertically displaced from the top of the drain outlet. The second rotational axis accomplishes the center of rotation holder of the first dividing member. |
