【摘要】 介绍了一种新型翻板闸门——防淤型底轴驱动式翻板闸门,此闸门在门叶底部设置了节流装置,利用闸内外水位差,在闸门底轴与底坎间的间隙中形成动能足够的水流对门库进行冲刷,这种冲淤措施不但节能且有效解决底轴驱动式翻板闸门的门库淤积问题。更多还原

【Abstract】 A Siltation Prevention Scheme of Bottom-axis Flap Gate is proposed, and a new type of gate, Prevent Siltation Bottom-axis Flap Gate was introduced. Throttle device is installed at the bottom of the gate frame. By using the difference of water level between the inside and outside of the gate, enough kinetic energy is formed in the gap between the bottom shaft and the bottom sill to scour the gate chamber. This kind of scouring and silting measure not only saves energy, but also effectively solves the problem of siltation in the gate chamber.更多还原
