The present invention relates to a winch for opening and closing a floodgate, capable of preventing an accident caused by a flood by enabling a floodgate to be open regardless of operation of a driving motor in a blackout. The winch for opening and closing a floodgate includes: a winding reel installed in a driven shaft installed in a main housing to rotate, wherein a rope for opening and closing the floodgate is wound on the winding reel; a sub housing installed in the housing, wherein a driving shaft connected to the driven shaft by a first power transfer unit is installed in the sub housing; a rotation member wherein a driving worm wheel engaged with a driving worm rotating by the driving motor is installed on the outer circumference of the rotation member, and the driving shaft installed in the sub housing is supported; a rotation control shaft installed in the sub housing and supported by the rotation member on the same axis as that of the driving shaft; a power control unit rotating the rotation member and the driving shaft at the same time when the rotation control shaft is fixed, by being installed in the rotation member, wherein the power control unit rotates the rotation control shaft and the driving shaft at the same time while the rotation of the rotation member is fixed by the driving worm wheel when the rotation control shaft rotates; and a rotation control shaft control unit installed in the housing and rotating the rotation control shaft when a water level rise to or above a predetermined water level, wherein the rotation control shaft control unit fixes the rotation of the rotation control shaft when the water level is equal to or lower than the predetermined water level.
