PROBLEM TO BE SOLVED: To provide a robot for a cleaning device for a wall surface of a large fish tank for display in an aquarium, having size and weight easily operable with a single hand, structured to prevent an electric shock accident to a worker and displayed fishes and affection of electromagnetic waves to the fishes, getting a pressing force required for cleaning by imparting a suction force to the cleaning device, cleaning contaminated water and returning it to the fish tank, and preventing the water to become hazy.SOLUTION: There is provided a cleaning device in which two wiping disk bodies 4, 5 are disposed parallelly, each rotated each in opposite directions to cancel rotational reaction force transmitted to the cleaning device, and eccentrically moved in opposite phases by the same displacement to widen a cleaning region, thereby improving wiping efficiency. A water suction pump imparts suction force to the cleaning device, using an air motor 3 as a power source, does not requires wiring in water, and prevents piping from sinking by the buoyant force of an air tube. Stubborn stain scattering on the fish tank wall surface can be efficiently and elaborately cleaned by replacement to a pencil type topical cleaning device without using any tool.COPYRIGHT: (C)2013,JPO&INPIT【課題】水族館大型展示水槽用壁面清掃装置において、片手で容易に操作できる大きさと重量であり、作業者及び展示魚類の感電事故ならびに魚類に及ぼす電磁波の影響を防止する構造とし、清掃装置に吸引力を与え清掃に必要な押し付け力を得、汚れた排水は浄化して水槽に戻し水槽の濁りを防止するロボットを提供する。【解決手段】2個の円盤清拭体4,5を並列に配し、互いに逆方向に回転させることにより、清掃装置に伝わる回転反力を打ち消し、さらに2個の円盤清拭体4,5を逆位相で同変位量だけ偏心運動させることにより、清掃領域が広くし、清掃効率が向上する。エアモータ3を動力源として用い、吸水ポンプで清掃装置に吸引力を与え、水中に電線を配する必要がなくエアチューブの浮力で配管の沈みを防止する。水槽壁面に点在する強固な汚れは、工具不要簡単取り替えにてペンシル型局所用清掃装置に交換し、能率の良いきめ細かな清掃に寄与できる。【選択図】図2
