PROBLEM TO BE SOLVED: To prevent water immersion into an elevator tower with a simple structure at low cost.SOLUTION: A flood prevention device for preventing water immersion into a tower 10 by a waterproof panel 2 when probability of water immersion occurs on a landing 1 of an elevator comprises: a waterproof panel 2 for preventing water immersion into an elevator tower 10; and a second hydraulic jack 8 for gradually raising the waterproof panel 2 from a floor face 1a of a landing 1. The second hydraulic jack 8 is driven with a first hydraulic jack 7 for lifting a car installed in the elevator tower 10 by hydraulic pressure, by switching control of a direction switching valve 6 by a hydraulic unit 5, and performs both of lifting drive of a car 3 and raising of the waterproof panel 2.SELECTED DRAWING: Figure 2

    【課題】簡単かつ低コストでエレベータ塔内への浸水を防止する。【解決手段】エレベータ塔内10への浸水を防止する防水パネル2と、エレベータの乗り場1に浸水のおそれが生じたとき、防水パネル2により塔内10への浸水を防止する浸水防止装置において、防水パネル2を乗り場1の床面1aから競りあがらせて浸水を防止する第2の油圧ジャッキ8を備えた。第2の油圧ジャッキ8は、エレベータ塔10内に設置された乗りかごを油圧で昇降させる第1の油圧ジャッキ7とともに油圧ユニット5に方向切替弁6の切替制御によって駆動され、乗りかご3の昇降駆動と防水パネル2のせり上げの両動作を行わせる。【選択図】図2
