Description

This invention relates to a water-stopping device that prevents water from entering openings in buildings, underpasses, etc., during floods. When floodwaters from typhoons or torrential rains enter openings in buildings and underpasses, they can cause significant damage. To prepare for such situations, a conventional method has been developed in which grooved support columns are erected opposite each other on both sides of openings in buildings and underpasses, and water-blocking plates are stored near these columns. When flooding occurs, the water-blocking plates are inserted into the grooves of the columns to close the openings and prevent water from entering (see Patent Document 1). However, with such conventional technology, the water level may rise above the height that the water-stopping plate can stop, and the increased water may overflow the water-stopping plate. Therefore, it is conceivable to set the water-stopping plate higher in advance to anticipate such flooding.

Next, embodiments of the present invention will be described in detail with reference to the drawings. <First Embodiment> Next, a specific embodiment having the above-described features will be explained in detail with reference to the drawings. The water-stopping device 1 comprises a water-stopping plate 10 positioned to intersect the flow of water, and left and right water-stopping support parts 20, 20 that support the water-stopping plate 10 on both sides, and is installed on a stationary surface such as a floor so as to close off an opening in a building or the like. In the illustrated example, the one side and the other side are the outdoor side and the indoor side, respectively. Alternatively, one side may be the indoor side and the other side the outdoor side. Furthermore, in the illustrated example, the outdoor side is the upstream side of the water flow and the indoor side is the downstream side. However, in another example, the water-stopping plate 10 can be installed in the opposite direction, so that the indoor side is the upstream side and the outdoor side is the downstream side. The water-stopping plate 10 comprises a main water-stopping plate 11 extending between the left and right water-stopping body support parts 20, 20, and an auxiliary water-stopping plate 12 facing the main water-stopping plate 11, which moves upward due to buoyancy (rotates upward in the illustrated example) to increase the water-stopping height.
