Normally-open overflow drainage gate structure for medium and large flow
The invention provides a normally-open overflow drainage gate structure for medium and large flow. A gate valve of the normally-open overflow drainage gate structure comprises a central gate plate andtwo sliding gate plates installed on the two sides of the central gate plate, wherein the bottom of the central gate plate and the bottoms of the sliding gate plates are each provided with a plurality of comb-tooth-shaped fixed gate pieces arranged at intervals; the two sliding gate plates stretch out in the width direction of a base; one end of a drive rod is provided with a worm section and a threaded section in threaded fit with the sliding gate plates; the worm section is in transmission connection through a worm gear arranged in the sliding gate plates and connected with a gear assembly;a cylindrical gear at the output end of the gear assembly is engaged with a horizontally-arranged rack; the rack is integrally arranged on a crutch-shaped turning rod; and a turning handle section ofthe turning rod inclines towards the upper right portion so as to press and push a sliding ejector rod at the corresponding position. By means of the normally-open overflow drainage gate structure, rapid installation and construction of a drainage gate of a riverway drainage opening can be achieved, large water flow impact is resisted, and adaptability is good.
本发明提供了一种应对中大流量的常开溢流排水闸结构，其闸阀包括一块中央闸板和安装于中央闸板两侧的两块滑动闸板，中央闸板和滑动闸板的底部均具有间隔布置的若干梳齿状的固定闸片；两滑动闸板各自沿着基座宽度方向上伸出，驱动杆一端具有蜗杆段以及与滑动闸板螺纹配合的螺纹段，蜗杆段通过设于滑动闸板内的与一个齿轮组件相连的蜗轮传动连接，齿轮组件输出端的圆柱齿轮与水平设置的齿条啮合，该齿条一体式地设置在一根拐杖状的拐杆上，拐杆的拐柄段朝右上方倾斜以压推相应位置的滑动顶杆。本发明能实现河道排水口的排水闸的快速安装施工，抵挡较大的水流冲击，适应性较好。
