Anti-backflow rainwater drainage system
The anti-backflow rainwater drainage system comprises a drainage ditch and a drainage port unit, a control valve is arranged at an outlet of a drainage pipe in the drainage port unit, the control valve comprises a spherical valve element, and when the water level of a river channel is lower than the water level of a water collecting pool, the control valve automatically opens a camera to drain water, so that surface water accumulation is avoided; when the water level of the river channel is higher than that of the water collecting tank, the control valve is automatically closed to prevent the river water from flowing backwards, manual operation is not needed, operation cost is reduced, drainage can be achieved, and the drainage effect is improved; the outlet well of the drainage port unit is arranged below the designed water level of the river channel, so that the river channel landscape is not influenced, and the river channel slope is prevented from being scoured by water flow; the grassland filter belt and the shrub filter belt are planted on the surface and the two sides of the drainage ditch respectively, pollutants of rainwater are filtered, and pollution of the rainwater to the river channel is reduced.
本发明公开了一种防倒灌的雨水排河系统，包括排水沟和排水口单元，在排水口单元内的排水管出口设置控制阀，其中控制阀包括球形的阀芯，当河道水位低于汇水池水位时，控制阀自动打开相机排水，避免地面积水，当河道水位高于汇水池水位时，控制阀自动关闭防河水倒灌，无需人工操作，降低运行成本，能相机排水，提高了排水效果；排水口单元的出口井设置于河道设计水位以下，既不影响河道景观又避免了水流对河道坡面的冲刷；在排水沟的表面和两侧分别种植有草地过滤带和灌木过滤带，对雨水的污染物进行过滤，降低了雨水对河道的污染。
