近年都市部住宅地において、集中豪雨被害が多発している。しかし、１時間当たり５０ｍｍ以上の豪雨に襲われると既存下水道の排水処理能力が超えるために、道路冠水や住宅地域の床下浸水被害等に見舞われることがある。特に、床下浸水時における水害被害に対しては、通常住居回りに土嚢を積んで対応していたが、土嚢での対応は、基本的に玄関周りに限られており、住宅基礎にあるすべての通気孔に対処できない場合が多い。 In recent years, torrential rain damage has frequently occurred in urban residential areas. However, heavy rains of 50 mm or more per hour may cause road floods and subsurface inundation damage in residential areas because the drainage capacity of the existing sewerage system is exceeded. In particular, flood damage during floods under the floor has usually been covered with sandbags around the dwellings, but sandbags are basically limited to the area around the entrance, and all housing foundations In many cases, it can not cope with the vent.

これに対して、特許文献１では、止水部材の上面までは止水効果を得ることができるが、それ以上の場合には、開口部から浸水するという問題点がある。また、特許文献２で開示される止水装置では、水害警報が発令された場合に、開口部を蓋状止水板で塞ぐため、水害警報の発令が遅れた場合や、局地的な大雨などの場合、止水板の設置が間に合わなかった場合には、開口部からの浸水を許す結果となるという不具合を有する。 On the other hand, in Patent Document 1, although the water blocking effect can be obtained up to the upper surface of the water blocking member, in the case of more than that, there is a problem that the water is flooded from the opening. Further, in the water blocking device disclosed in Patent Document 2, when the flood warning is issued, the opening portion is closed by the lid-like water blocking plate, so that the issue of the flood warning is delayed or a localized heavy rain In such a case, if the installation of the water blocking plate can not be made in time, there is a problem that it will result in allowing water immersion from the opening.

以上のことから、本発明は、床下換気口に装着し、通常時は換気口からの換気を維持すると同時に、浸水時には換気口からの浸水防止を提供するものである。 From the above, the present invention is mounted on an underfloor vent, and normally provides ventilation from the vent, and at the same time, when water is flooded, it provides the flood prevention from the vent.

本発明は、換気口前面に配置され筐体の換気口と浮力を生じる扉体より形成され、換気口浸水防止装置内に水が浸水する事により、換気口を塞ぐ機構を具備するものである。 The present invention is provided with a vent provided at the front of the vent and formed from the vent of the housing and a door for generating buoyancy, and has a mechanism for closing the vent by water being flooded in the vent flood prevention device. .

浸水防止装置内の水位の上昇に伴って扉体の浮力材と水圧により扉体を持ち上げ、換気口を完全に閉塞する。 With the rise of the water level in the inundation prevention device, lift the door by the buoyancy and water pressure of the door, and completely close the vent.

閉塞した扉体は、水圧により押さえ着けられ密着シール面と膨張するシール面の２重シール構造を使い換気口への浸水を防ぐ。 The closed door is pressed by water pressure and uses a double seal structure with an intimate sealing surface and an expanding sealing surface to prevent water from entering the ventilation port.

本発明の換気口浸水防止装置によれば、換気口の前面に沿って配置するだけで、水位の上昇に伴って換気口を閉塞できるとともに、水位の下降に伴い換気口を再度開放できるため、基本的に何度でも換気口からの浸水を防止できるものである。また、作業しやすい時に設置できるため、大雨の中で土嚢を積んだり、シートを配したりする必要がないため、危険な作業がなくなるという効果を奏する。 According to the ventilating port inundation prevention device of the present invention, the ventilating port can be closed along with the rise of the water level only by arranging along the front face of the ventilating port, and the ventilating port can be reopened along with the descent of the water level. Basically, it is possible to prevent flooding from the ventilation port any number of times. In addition, since it is possible to install when it is easy to work, there is no need to load sandbags in heavy rain or to arrange sheets, there is an effect that dangerous work is eliminated.
