PROBLEM TO BE SOLVED: To provide an intake apparatus capable of efficiently removing, despite its small size, floating matter near the water surface, and easy to clean inside thereof.SOLUTION: A water intake apparatus 34 is provided with an intake part 42 positioned in water. The intake part 42 includes: a trunk cylinder 46 in a cylindrical shape fixed in water and vertically extending an upper cylinder 48 in a thin cylindrical shape detachably fitted to the trunk cylinder 46 from above and a float 50 fixed inside the upper cylinder 48, the upper end of the float being positioned lower than the upper end of the upper cylinder 48. By the float 50, according to the water level change inside the intake part 42, the upper cylinder 48 is allowed to vertically move fitted to the trunk cylinder 46. When water is discharged from the intake part 42, the upper cylinder 48 moves downward as the water level inside the intake part 42 goes down, water flows into the intake part 42 from the upper side of the upper cylinder 48.COPYRIGHT: (C)2016,JPO&INPIT【課題】水面近くの浮遊物を小さなサイズで効率よく除去でき、内部清掃が容易な取水装置の提供。【解決手段】この取水装置34は、水中に位置する取水部42を備えている。上記取水部42は、水中で固定され上下に延びる筒状を呈する胴筒46と、この胴筒46に上から脱着可能に嵌め込まれ薄肉の筒状を呈する上筒48と、この上筒48の内側に固着されその上端が上筒48の上端より下に位置するウキ50とを備えている。上記ウキ50により、上記取水部42内部の水位の変化に従って上記上筒48は上記胴筒46に嵌め込まれたまま上下に移動可能となっている。この取水部42から水を排出したとき、上記取水部42の内部の水位が下がることで上筒48が下に移動し、上記上筒48の上側から水が上記取水部42に流れ込む。【選択図】図2
