ROLLER TYPE WATER GATE
PROBLEM TO BE SOLVED: To provide a roller type water gate which enables rotation states of rollers to be easily confirmed.SOLUTION: A water gate 100 (roller type water gate) comprises: a water gate body 2 which is moved up and down in a manner that opens and blocks distribution of water; doorstops 12 which are extended in a direction that the water gate body 2 is moved up and down; and rollers 21 which are installed on the water gate body 2 and rotated along with up-and-down movement of the water gate body 2 with the same brought into contact with the doorstops 12. The water gate 100 also has non-contact sensors 25 which detect rotation states of the rollers 21 along with up-and-down movement 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
