ROLLER TYPE WATER GATE AND ROLLER ROTATION STATE DETERMINATION METHOD OF ROLLER TYPE WATER GATE
To provide a roller type water gate allowing a rotation state of a roller to be easily confirmed.SOLUTION: A water gate 100 (roller type water gate) includes: a water gate body 2 elevating or lowering so as to open or block circulation of water; gate guides 12 extending in an elevating/lowering direction of the water gate body 2; and rollers 21 which are provided on the water gate body 2 and are rotated along with elevation and lowering of the water gate body 2 in a state in contact with the gate guides 12. The water gate 100 includes non-contact sensors 25 which detect rotation states of the rollers 21 along with elevation and lowering of the water gate body 2.SELECTED DRAWING: Figure 8
【課題】ローラの回転状態を容易に確認させることが可能なローラ式水門を提供する。【解決手段】この水門１００（ローラ式水門）は、水の流通を開放または遮断するように昇降する水門本体２と、水門本体２の昇降方向に延びる戸当たり１２と、水門本体２に設けられ、水門本体２の昇降に伴い、戸当たり１２に接触した状態で回転するローラ２１と、を備える。また、水門１００は、水門本体２の昇降に伴う、ローラ２１の回転状態を検出する非接触センサ２５を備える。【選択図】図８
