Double-rotating-shaft self-resetting flap gate
The invention discloses a double-rotating-shaft self-resetting flap gate which is an improvement on a small-sized flap gate technology without an automatic resetting function. The double-rotating-shaft self-resetting flap gate comprises a gate body which is positioned in a gate chamber and can rotate around double transverse shafts, and a notch and a hinge plate which can be turned upwards are arranged at the top of the gate body. The transverse shafts comprise the upper transverse shaft and the lower transverse shaft and are fixed to one side of the downstream portion of a gate plate, a semicircular front shaft sleeve and a semicircular rear shaft sleeve with upward openings are correspondingly fixed on the side walls, the lower transverse shaft is arranged in the rear shaft sleeve to rotate when the gate body is erected, and the upper transverse shaft is arranged in the front shaft sleeve to rotate when the gate body is turned over. Limiting buffer blocks are arranged on the side walls of the gate chamber and are lower than the front shaft sleeve. A balancing weight is arranged at the bottom of the gate body. According to the flap gate provided by the invention, the flap gate is vertical to be used for retaining water in a low water period, and the hinge plate is flatly laid underwater; the hinge plate is automatically turned up during flood, the gate body is automatically turned over and is in contact with the front shaft sleeve and the limiting buffer blocks in sequence, and full-open flood discharge is achieved; and when the flood flow is reduced, the gate body is automatically reset by virtue of the balancing weight and hydrostatic pressure.
本发明公开了双转轴自复位翻板闸，是对无自动复位功能的小型翻倒闸技术的改进，包括位于闸室内可绕双横轴旋转的闸门，闸门顶设缺口和可向上翻起的活页板。横轴包括上横轴和下横轴，固定在闸门板下游一侧，相应在侧墙上固定有开口向上的半圆形前轴套和后轴套，闸门竖立时下横轴置于后轴套内转动，闸门翻倒则上横轴置于前轴套内转动。闸室侧墙设有限位缓冲块，位置高度低于前轴套。所述闸门底部设有配重块。本发明提供的翻板闸在枯水时竖立挡水，活页板平躺于水下，洪水时活页板自动翻起，闸门自动翻倒，依次接触前轴套和限位缓冲块，达全开泄洪，当洪水流量变小，闸门靠配重和静水压力自动复位。
