ORGANISM ADHESION PREVENTIVE DEVICE, AND CONDUIT
PROBLEM TO BE SOLVED: To provide an organism adhesion preventive device and a conduit capable of suppressing adhesion of organisms on an inner surface of the conduit, while maintaining water-conveyance efficiency.SOLUTION: An organism adhesion preventive device 2 is provided for suppressing adhesion of organisms on an inner surface of a conduit 1. The organism adhesion preventive device 2 includes a cathode 3c and an anode 3a constituting an electrode 3 that causes an electric current to flow through water, and an electric power unit 4 for suppressing applied voltage on the electrode 3 and polarity inversion. The cathode 3c and the anode 3a are disposed alternately in a circumferential direction on the inner surface of the conduit 1. The conduit 1 is divided into a plurality of segments 5 in the circumferential and axial directions. The segment 5 includes an electrode plate 55 disposed on an inner side constituting the inner surface of the conduit 1, and an insulating part 56 formed on an outer periphery of the electrode plate 55.SELECTED DRAWING: Figure 1
【課題】導水効率を維持しつつ導水路の内表面への生物付着を抑制することができる、生物付着防止装置及び導水路を提供する。【解決手段】導水路１の内表面への生物付着を抑制する生物付着防止装置２を備え、生物付着防止装置２は、水中に電流を流す電極３を構成するカソード３ｃ及びアノード３ａと、電極３の印加電圧及び極性反転を制御する電源装置４と、を備え、導水路１の内表面の周方向にカソード３ｃ及びアノード３ａが交互に配置されている。また、導水路１は、周方向及び軸方向に複数に分割されたセグメント５により構成されており、セグメント５は、導水路１の内表面を形成する内側に配置された電極板５５と、電極板５５の外周に形成された絶縁部５６と、を備えている。【選択図】図１
