description PROBLEM TO BE SOLVED: To smoothly carry out vertical movement of a dust inflow preventing tool in response to a water level. SOLUTION: The floating dust inflow preventing device 1 is provided in an inlet side of a water intake 3 facing a water passage 2 to prevent inflow of floating dust D. It is provided with: a shaft member 10 erected in an upstream side of the inlet side of the water intake 2; the dust inflow preventing tool 11 with one end side 11a in an upstream direction supported by the shaft member 10 such that vertical movement and oscillating movement in a circumferential direction are possible, and preventing inflow of the dust D into the water intake 3 by vertically moving in response to the water level of water passage 2 by buoyancy and vertically cutting across a water surface of the water passage 2; and an oscillating means 12 having a guide groove 17 and a guide pin 19 carrying out guiding by the guide groove 17, and oscillating the dust inflow preventing tool 11 such that the other end side 16b in a downstream direction of the dust inflow preventing tool 11 contacts and separates away from the water intake 3 following the vertical movement of the dust inflow preventing tool 11. The guide pin 19 is fixed to the one end side 11a of the dust inflow preventing tool 11, and the guide groove 17 is fixed to a neighborhood of the one end side 11a. COPYRIGHT: (C)2008,JPO&INPIT
