NOZZLE DEVICE, PIPE CLEANING DEVICE AND DRAINAGE VERTICAL PIPE CLEANING METHOD
To provide a nozzle device, a pipe cleaning device, and a drainage vertical pipe cleaning method to clean rust and other adhering matter adhering hard to an inner wall of a pipe by mechanical impact without using a driving force of a motor or the like.SOLUTION: A nozzle device comprises: a tubular shaft body portion that is connected to a pressure resistant hose and has a tubular shaft body with a drain port on a side surface of a pipe; a nozzle head that is rotatably and slidably supported on the shaft body, has at least one injection port for injecting water supplied from the drain port, and is rotated by a reaction force of water injection; a disc-shaped portion that extends from the side of the nozzle head and does not interfere with the injecting water; and at least one blade member that is supported by a support shaft erected on the disc-shaped portion so as to rotate on a rear end side, whose tip side opens toward a distance from the support shaft due to a centrifugal force caused by the rotation of the nozzle head.SELECTED DRAWING: Figure 1
【課題】モータ等の駆動力を用いずに、配管内壁に固く付着した錆等の固着物に機械的な衝撃を与えて清浄化するためのノズル装置、配管清浄化装置及び排水縦管清浄化方法提供する。【解決手段】耐圧ホースに接続され、排水口を管側面に有する管状の軸体を備える管状軸体部と、軸体に回転摺動自在に軸支され、排水口から供給された水を噴射する少なくとも一つの噴射口を備え、水の噴射の反力によって回転するノズルヘッドと、ノズルヘッドの側面から延出し、水の噴射に干渉しない盤状部と、盤状部に立設された支持軸に後端側で回動するように支持されており、ノズルヘッドの回転による遠心力により、先端側が支持軸から遠方に向かって開く少なくとも１つのブレード部材と、を備える、ノズル装置を用いる。【選択図】図１
