WATER GATE OPENING/CLOSING DEVICE AND ITS OPENING/CLOSING METHOD
To allow the stable own-weight descent of a door body of a water gate while maintaining its equilibrium state.SOLUTION: In a water gate opening/closing device 1, a pair of opening/closing device bodies 15 including elevating means, power generating mechanisms 29 and variable resistors 27 are each independently arranged on both sides in a width direction of a door body 3, and the power generating mechanisms 29 generate power by receiving a descending operation of the door body 3 when the door body 3 descends by its own weight. Each of the variable resistors 27 consumes the power generated in the power generating mechanisms 29, and imparts resistance to each of the power generating mechanisms 29. Furthermore, the water gate opening/closing device 1 includes a control device 55 which controls each of the resistance values of the variable resistors 27 when the width direction of the door body 3 is inclined with respect to the width direction of the water gate 2 during the own-weight descent, and adjusts a brake force by a power generating brake in each of the power generating mechanism 29, and thereby corrects an inclination attitude of the door body 3. Thereby, it is possible to stably descend by its own weight of the door body 3 while maintaining its equilibrium state.SELECTED DRAWING: Figure 1
【課題】水門の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。【解決手段】水門開閉装置１は、昇降手段、発電機構２９及び可変抵抗器２７を含む開閉装置本体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たものであり、発電機構２９は、扉体３を自重で降下させる際、扉体３の降下動作を受けて電力を発生するものである。各可変抵抗器２７は、発電機構２９において発生する電力を消費するためのものであり、各発電機構２９に抵抗を付与する。更に、水門開閉装置１は、自重降下中に扉体３の幅方向が水門２の幅方向に対して傾斜した場合に、可変抵抗器２７の各々の抵抗値を制御し、発電機構２９の各々において発電ブレーキによる制動力を調整することで、扉体３の傾斜姿勢を補正する制御装置５５を備えている。これにより、平衡状態を維持しながら、扉体３を安定して自重降下させることが可能となる。【選択図】図１
