WATER GATE OPENING/CLOSING DEVICE AND OPENING/CLOSING CONTROL METHOD THEREFOR
To provide a water gate opening/closing device and opening/closing control method therefor, capable of making a door body stably descend by self-weight while keeping its equilibrium state.SOLUTION: A water gate opening/closing device 1 includes a pair of opening/closing device bodies 15, 15 independently arranged on both sides in a door body 3's width direction. Each opening/closing device body 15 comprises a fan brake 40 having a damper 41 and a door body opening deflection meter 52 for detecting a position, at the time of self-weight descending, on a corresponding side of both sides in the width direction of the door body 3 where at least one of fan brakes 40 comprises damper opening adjustment means 42. The water gate opening/closing device 1 comprises a control device 55 that when the door body 3's posture in the width direction is inclined during the self-weight descending of the door body 3, controls opening of a damper 41 of at least one of the fan brakes 40 to correct its inclined posture.SELECTED DRAWING: Figure 1
【課題】扉体をその平衡状態を維持しながら安定して自重降下させることのできる水門開閉装置及びその開閉制御方法を提供する。【解決手段】水門開閉装置１は、開閉装置本体１５、１５が、扉体３の幅方向両側にそれぞれ独立して一対配置されており、各開閉装置本体１５は、ダンパ４１を有するファンブレーキ４０と、扉体３の幅方向両側における自重降下時の位置をそれぞれ検出する扉体開度偏差計５２とを備え、少なくとも一方のファンブレーキ４０は、ダンパ開度調整手段４２を備えている。また、水門開閉装置１は、扉体３の自重降下中、扉体３の幅方向の姿勢が傾斜した場合、ファンブレーキ４０の少なくとも一方のダンパ４１の開度を制御して、その傾斜姿勢を補正する制御装置５５を備えている。【選択図】図１
