ROTARY WATER SPRINKLER

To provide a rotary water sprinkler that does cause hindrance to rotary operation due to a floating matter or the like contained in treatment target water.SOLUTION: A rotary water sprinkler 200 includes: a first pipe 201 arranged such that its axial direction runs along a vertical direction and having a water inflow port to the inside; a rotary supporting part 202 for rotatably supporting the first pipe around a shaft; a water receiving part 210 installed in the first pipe and receiving water to flow into the water inflow port 211; a second pipe 207 connected so as to communicate with the inside of the first pipe from a point lower than the water receiving part of the first pipe and extending in a lateral direction, and integrally rotating with the first pipe; water ejection parts 208 which are arranged at prescribed intervals in a length direction of the second pipe and at least one of which is open laterally; and a water supply pipe 111 for supplying water to the water receiving part. The first pipe and the second pipe are configured to integrally rotate by force of the water ejecting from the water ejection parts.SELECTED DRAWING: Figure 2 【課題】被処理水に含まれる浮遊物等によって回転動作に支障が生じることがない回転式散水装置を提供する。【解決手段】この回転式散水装置２００は、軸方向が上下方向に沿うように配設され、内部への水流入口を有する第１配管２０１と、前記第１配管を軸周りに回転可能に支持する回転支持部２０２と、前記第１配管に装着され、前記水流入口２１１へ流入させる水を受ける水受け部２１０と、前記第１配管の前記水受け部よりも下方から、前記第１配管の内部に連通するように連結されて横方向に延び、前記第１配管と一体に回転する第２配管２０７と、前記第２配管の長さ方向に所定間隔で設けられ、そのうちの少なくとも１つが横向きに開口している水噴出部２０８と、前記水受け部に水を供給する水供給管１１１とを備え、前記水噴出部から噴出する水の勢いによって、前記第１配管及び前記第２配管が一体に回転するように構成されている。【選択図】図２
