新型直升式城市防洪闸门及应用

摘要

新型直升式城市防洪闸门主要包括闸门门叶、密封槽、混凝土基础和启闭装置。当闸门门叶到达全闭位置时，闸门门叶和密封槽之间的斜面机构提供一个水平预紧力，从而使闸门门叶和密封槽紧密结合以阻挡洪水。启闭装置提供动力，使闸门门叶在精密配合的密封槽内快速而平稳地升降。%New type vertical-lift flood gate in the city includes gate leaf, seal groove, concrete foundation and hoist. When the gate leaf is completely closed, the oblique mechanism between gate leaf and seal groove will offer horizontal pretighten-ing force which can ensure good sealing effect. The hoist will provide power to make gate leaf lift quickly and smoothly in seal groove.
