Hydropower station unattended mode hydraulic steel gate mechanical stroke indicating device

The invention provides a hydropower station unattended mode hydraulic steel gate mechanical stroke indicating device which comprises a hydraulic cylinder used for being connected with a hydraulic steel gate and a supporting plate, a first guide pulley is installed on one side of the upper surface of the supporting plate, and a second guide pulley is installed on the side, away from the first guidepulley, of the upper surface of the supporting plate. The side face, close to the second guide pulley, of the supporting plate is fixedly connected with an indicating plate, the head of a piston rodof the hydraulic cylinder is connected with a steel wire rope, and the end, away from the hydraulic cylinder, of the steel wire rope sequentially bypasses the winding drum, the first guide pulley andthe second guide pulley and penetrates through the first rope penetrating hole to extend into the limiting groove. The end, located in the limiting groove, of the steel wire rope is connected with a counter weight. Compared wit
