    • A boot seal for a vertically traveling water screen and a method forming a boot seal. The boot seal comprises a bent plate extending from an attachment end to a free end. The attachment end attachedes to a frame at the bottom of a channel of water flowing through the screen. The seal is positioned upstream of the upward-moving upstream face of the screen. The free end of the bent plate in a rest position is close to or lightly touching the upstream face of the screen. The bent plate has a concave surface facing the screen and acts as a cam follower to a passing lift element's cam. As the lift element slides along the cam surface, it pivots the boot plate in an upstream direction against a spring bias. When the lift element clears the boot plate, the boot plate springs back to its rest position.
    • 用于垂直行进的水幕的靴子密封件和形成靴子密封件的方法。 靴形密封件包括从附接端延伸到自由端的弯曲板。 附着端附着在流过屏幕的水流通道底部的框架上。 密封件位于屏幕向上移动的上游面的上游。 弯曲板的静止位置的自由端靠近或轻微接触屏幕的上游面。 弯曲板具有面向屏幕的凹形表面,并且用作通过提升元件的凸轮的凸轮从动件。 当升降元件沿着凸轮表面滑动时,其抵抗弹簧偏压使靴板在上游方向上枢转。 当提升元件清除护罩板时,护罩板弹回到其静止位置。
