The present invention relates to a floodgate capable of remarkably reducing manufacturing costs, stably transmitting power, and stably controlling a flow rate and a water level. The floodgate comprises: a vertical first spindle (20) transmitting rotating force transmitted by an actuator (10) to a lower portion separated at a predetermined height; a gear box (30) converting a rotation direction of the rotating force transmitted through the first spindle (20); a horizontal second spindle (40) transmitting rotating force to a predetermined separated distance in the rotation direction changed by the gear box (30); a first sheave (50) rotated by the rotating force transmitted by the second spindle (40); a first wire rope (60) having one end fixed to the first sheave (50) to be wound by a predetermined length and the other end connected to one upper end portion of a sluice (G); and a second wire rope (80) having one end fixed to the first sheave (50) to be wound by a predetermined length and the other end connected with the other upper end portion of the sluice (G) by being wound around a second sheave (70) provided on a guide wall (90) corresponding to the first sheave (50) through a rope guide tube (92) horizontally fixed to a water path bottom surface (91). |
