PROBLEM TO BE SOLVED: To provide an inexpensive emergency shutdown device, easily installable on a bottom surface or a side surface of a drain channel, and capable of surely shutting down drain water of the drain channel by a simple procedure.SOLUTION: In an emergency shutdown device 10 for connecting a first connection plate 1, a bellows structure part 2 and a second connection plate 3 in series so as to form a cavity part on the inside, the emergency shutdown device is provided so that the first connection plate is fixed to a drain port in the drain port installed on a side surface or a bottom surface of the drain channel, and the emergency shutdown device is fixed, and the bellows structure part is normally folded up, and drain water is drained by always flowing to the cavity part from the second connection plate, on the one hand, the second connection plate and the bellows structure part are lifted in an emergency, and the second connection plate is lifted up to a position above a water surface of the drain water, and the drain water flowed in from the second connection plate is shut down.SELECTED DRAWING: Figure 1
【課題】排水路の底面あるいは側面に簡易的に設置することが可能であって、簡単な手順にて、確実に排水路の排水を遮断できる低価格な緊急遮断装置を提供する。【解決手段】第１の接続板１と、蛇腹構造部分２と、第２の接続板３とが、内部に空洞部を形成するように、直列に接続された緊急遮断装置１０であって、排水路の側面、あるいは底面に設置された排水口に、前記第１の接続板が、排水口に固着されて、前記緊急遮断装置が固定され、通常時は、前記蛇腹構造部分が折りたたまれ、第２の接続板から、排水が、前記空洞部に、常時流れて、排水されており、一方、緊急時には、前記第２の接続板、前記蛇腹構造部分が持ち上げられ、前記第２の接続板が、前記排水の水面以上の位置まで、持ち上げられて、第２の接続板から流れ込んでいた排水が遮断される緊急遮断装置とする。【選択図】図１
