PROBLEM TO BE SOLVED: To provide a rotary sprinkler which can arbitrarily change an installation location, does not require power such as electric power, and is capable of evenly sprinkling water within a fixed range around an installation location.SOLUTION: There is provided a sprinkler that consists of a cylindrical tank body and a rotary table at the central part of which a rotary support shaft is vertically erected, in which the tank body comprises: a water inlet provided at the center on an upper surface a plurality of spray nozzles provided for an outer peripheral surface a plurality of blades of a rectangular plate shape provided for the outer peripheral surface and a support shaft insertion hole provided for a bottom center. The rotary support shaft is inserted into the support shaft insertion hole to pivotally support the tank body freely rotatably on an upper part of the rotary table, and the tank body sprinkles water from the spray nozzle outside the tank body while rotating water poured from the water inlet into the tank body by wind pressure applied to the plurality of blades.COPYRIGHT: (C)2016,JPO&INPIT【課題】任意に設置場所を変更でき、かつ、電力等の動力を必要とせず、設置された場所を中心として一定の範囲内に均一に散水可能な回転式の散水装置を提供する。【解決手段】円筒形のタンク本体と、中央部に回転支軸が垂直に立設された回転台と、から構成される散水装置であって、前記タンク本体は、上面中央に設けられた注水口と、外周面に設けられた複数の噴射ノズルと、外周面に設けられた矩形板状の複数の羽根板と、底面中央に設けられた支軸挿入穴と、を備え、前記回転支軸を前記支軸挿入穴に挿入して、前記タンク本体を前記回転台の上部に回転自在に軸支し、前記タンク本体は、前記注水口から当該タンク本体の内部に注水された水を、前記複数の羽根板にかかる風圧により回転しながら前記噴射ノズルから当該タンク本体の外部に散水することを特徴とする散水装置とした。【選択図】図2
