INFLOW CUTOFF DEVICE
To provide a compact inflow cutoff device capable of cutting off inflow without any power in a flowing water direction of a water flowing passage and in an opposite direction to the flowing water direction upon rising of water level of an external water.SOLUTION: An inflow cutoff device is provided with: a water gathering basin 31 arranged in the middle of a water flowing passage; a lid member 40 rotatably attached on the water gathering basin 31; a float 50 arranged on an upper part of the lid member 40 and being displaced with change of a water level in the water gathering basin 31; and a connecting member 60 connecting the lid member 40 to the float 50. In the inflow cutoff device 30, the lid member 40 can move in an interlocked manner with the displacement of the float 50 between a cutoff position cutting off inflow to the water flowing passage (an upstream side drain main pipe 11, a downstream side intake main pipe 12A) connected to an area to be protected (a first building 5, a second building 6) and a release position releasing the water flowing passage (the upstream side drain main pipe 11, the downstream side intake main pipe 12A) connected to the area to be protected (the first building 5, the second building 6).SELECTED DRAWING: Figure 3
【課題】 外水域の水位上昇時に、流水路の流水方向および流水方向とは反対方向の流入を無動力で遮断可能なコンパクトな流入遮断装置を提供する。【解決手段】 流水路の途中に設けられた集水枡３１と、集水枡３１に回動可能に取り付けられた蓋部材４０と、蓋部材４０の上方に設けられ、集水枡３１内の水位の変動にともなって変位する浮体５０と、蓋部材４０と浮体５０とを連結する連結部材６０と、を備える。この流入遮断装置３０において、蓋部材４０は、浮体５０の変位に連動して、保護対象エリア（第１建屋５、第２建屋６）に接続された流水路（上流側排水本管１１，下流側取水本管１２Ａ）への流入を遮断する遮断位置と、保護対象エリア（第１建屋５、第２建屋６）に接続された流水路（上流側排水本管１１，下流側取水本管１２Ａ）を開放する開放位置と、の間を移動可能とする。【選択図】図３
