To provide a water shielding device which is compact and can be installed on a ceiling or the like, and a shelter provided with the water shielding device.SOLUTION: In a water shielding device 80, an inner cylinder part 50 combines the functions of an air passage, a float, and an opening/closing valve that opens/closes the passage. This makes it possible to compact the scale of the device and reduce its size. In addition, the movement of the inner cylinder part 50 is a simple vertical movement along a shaft 40, so the space required for the movement is small, which also contributes to the miniaturization of the device scale. Furthermore, since the inner cylinder part 50 is housed in an outer cylinder part 30 and the inner cylinder part 50 functions as a float, even a relatively small amount of water can make the inner cylinder part 50 float and make the water shielding device 80 closed. Accordingly, the amount of water stored in the outer cylinder part 30 can be reduced, and the weight in the closed state can be reduced. This makes it possible to install the water shielding device 80 on the upper part of a room such as a ceiling, so that the water shielding device 80 does not put pressure on the floor area and the indoor space can be effectively used.SELECTED DRAWING: Figure 1
【課題】コンパクトで天井等に設置が可能な遮水装置及びこれを備えたシェルタを提供する。【解決手段】この遮水装置８０は、内筒部５０が空気の流路と、フロートとしての機能と、流路を開閉する開閉弁との機能を兼ね備えている。このため装置規模をコンパクトにまとめ小型化することができる。また、内筒部５０の移動はシャフト４０に沿った単純な上下動のため、移動に必要な空間が小さく、これも装置規模の小型化に寄与する。さらに、外筒部３０内に内筒部５０を収容し、この内筒部５０をフロートとして機能させるため、比較的少量の水でも内筒部５０を浮上させ遮水装置８０を閉状態とすることができる。これにより、外筒部３０の貯水量を低減でき、閉状態時の重量を軽減することができる。これにより、遮水装置８０を天井等の室内の上部に設置することが可能となり、遮水装置８０が床面積を圧迫せず、室内空間を有効利用することができる。【選択図】図１
