PROBLEM TO BE SOLVED: To provide an automatic tsunami warning device that physically detects inundation of the tsunami and generates an automatic alert without depending on electricity, etc.SOLUTION: A hollow air container is placed in the sea side immediate vicinity of a breakwater, and the piping for introducing inundation upon inundation is connected in the lower part. The piping laid along the breakwater and for releasing air is connected on the upper part, and a rupture plate and a sound device (flute, etc) are installed therein. This air container is kept in a state with air coming inside in normal time and fixed at the constant point, so that water may come in from an inundation pipe of the lower part in the tsunami inundation and the air in the inside is shut and pressurized according to an inundation height. The rupture plate installed in the upper air discharge tube is ruptured when an air pressure becomes larger than a constant value, and the air falls out and generates sound when passing through the sound device, and thereby the inhabitants are alarmed that the tsunami reaches the level. The outlet of the air is directed toward the house side to make it easy to tell inhabitants. In response to some inundation level, multiple rupture plates are installed in a mass, and thereby the risk can be informed in a stepwise manner.SELECTED DRAWING: Figure 2
【課題】津波の浸水を物理的に検知し、電気などに頼らず、自動的警報を発生する。【解決手段】防波堤の海側直近に、中空の空気容器を置き、その下部に浸水時に浸水を導入する配管を繋ぎこむ。上部には、防波堤に沿わせるように敷設した空気放出用の配管を繋ぎ、その中に、破裂板と音響装置（笛など）を設置する。この空気容器は通常時、中に空気が入った状態であり、一定の地点に固定しておくので、津波浸水時、下部の浸水管から水が入ってきて、中の空気は閉じ込められ、浸水高さに応じて、加圧されていく。上部の空気放出管中に設置された破裂板は、空気圧が一定以上になった時に破裂し、空気が抜けて、音響装置を通る時に、音響を発生し、住民に対して津波がそのレベルに達したことを警報する。その空気の放出口を住居側に向け、住民に伝えやすくする。いくつかの浸水レベルに対応して複数まとめて設置することで、危険性を段階的に知らせることもできる。【選択図】図２
