To provide an emergency protection device which is housed in an embankment and the like as a device short in a longitudinal width without a diagonal member structure and which also strongly resists attack of a tsunami, a high tide and the like without a diagonal member structure and has no risk of breakage such as falling backward.SOLUTION: An emergency protection device comprises: a movable weir which is made to be a hollow body including front and rear plates forming a facing shape in the front and back, longitudinally long end plates provided at left and right end portions of the front and rear plates and a weir lid at a top end, and which is installed so as to vertically be lifted and lowered in an elongated groove-shaped pit formed inside a base in a region where a tsunami and a high tide are assumed to attack; and a lifting and lowering device driving the movable weir up and down between a waiting attitude of being housed in the pit and a lifted stopping attitude. The lifting and lowering device comprises a pantograph mechanism whose lower part is fixed to a bottom side of the pit and whose upper part is connected to an inside of an upper part of the movable weir, and a pantograph driving mechanism which includes a driving source and which drives the pantograph mechanism up and down.SELECTED DRAWING: Figure 2
【課題】斜材構造なしで前後幅の短い装置として堤防などに納められるだけでなく斜材構造なしで津波や高潮などの襲来に強く抵抗して後倒れなどの損壊のおそれのない非常用防護装置を提供することを目的とする。【解決手段】前後において対向状をなす前・後板とその左右端部に設けた縦長状の端板及び上端の堰蓋とを有する中空体とされ津波・高潮などの襲来が想定される地域の基盤内に形成された細長溝状のピット内に垂直昇降可能に装備した可動堰と、この可動堰をピット内に収まった待機姿勢と上昇した堰止姿勢とに昇降駆動させる昇降装置とを備える非常用防護装置であって、前記昇降装置は、下部がピット底部側に固定され上部が可動堰上部内に連結されたパンタグラフ機構と、駆動源を含むものでパンタグラフ機構を昇降駆動させるパンタグラフ駆動機構とを備えている。【選択図】図２
