Non-resistance self-draining backflow prevention flood drainage device
The invention discloses a non-resistance self-draining backflow prevention flood drainage device. The non-resistance self-draining backflow prevention flood drainage device mainly comprises a drainingwell, a water inlet pipe and a gravity drain pipe, and the water inlet pipe and the gravity drain pipe are arranged on the sidewall of the draining well. The bottom surface of the draining well is lower than the lower ends of the water inlet pipe and the gravity drain pipe. The non-resistance self-draining backflow prevention flood drainage device is further provided with a water collecting tankarranged beside the draining well. An overflow weir is arranged between the draining well and the water collecting tank, and the draining well and the water collecting tank are separated through the overflow weir. Water pumps are arranged in the water collecting tank and used for pumping water in the water collecting tank. A water pump drain pipe is connected to the water outlet ends of the waterpumps. A water outlet of the water pump drain pipe extends to the outside. A flap valve is mounted on the gravity drain pipe through a driving mechanism. The flap valve covers an external water outletof the gravity drain pipe. When the water level in the draining well is higher than the overflow weir, water overflows to the water collecting tank, and the water pumps are started to drain the waterin the water collecting tank outwards. The non-resistance self-draining backflow prevention flood drainage device can greatly improve the drainage capacity of cities and towns to prevent waterlogging.
本发明公开了一种无阻力自排防倒灌排涝装置，其主要包括排水井以及在排水井的侧壁上设置的进水管和重力排水管，排水井的底面低于进水管及重力排水管的下端，无阻力自排防倒灌排涝装置还在排水井的侧边设置集水池，在排水井与集水池之间设有溢流堰，通过溢流堰进行分隔，在集水池内设置有水泵，水泵用于抽取集水池中的水体，在水泵的出水端连接有水泵排水管，水泵排水管的出水口延伸至外部，在重力排水管上通过驱动机构安装有拍门，拍门盖设在重力排水管的外部出水口处；当排水井中的水位高于溢流堰时，将溢流至集水池，此时水泵启动向外排出集水池中的水体。本发明能极大的提高城镇的排水能力，防止水涝。
