AI Technical Summary

Technical Problem

Urban stormwater pipes have a slow flow rate, resulting in long drainage times and making cities prone to waterlogging and flooding.

Method used

The system employs a flood control and drainage rainwater pipeline conveyor, which includes a sedimentation device, a conveying device, and an automatic control device. It accelerates the flow of rainwater through a motor-driven rotating cutter and impeller, and automatically controls the motor's start and stop using a water level and pressure switch, thereby achieving automatic sedimentation, cutting, and rapid delivery of rainwater.

Benefits of technology

It increases the flow rate of rainwater pipes, reduces drainage time, avoids urban waterlogging and flooding disasters, and ensures timely, safe and efficient rainwater transportation and drainage.

Abstract

This invention discloses a stormwater drainage system for flood control and drainage, relating to the field of urban flood control and drainage engineering technology. It includes a stormwater well, a sedimentation device, a drainage device, and an automatic control device. The sedimentation device includes a sedimentation tank installed at the bottom of the inner wall of the stormwater well. A clamp is installed at the top of the sedimentation tank, and a platform is installed inside the clamp. Mounting holes are provided at the center of the top of both the clamp and the platform, and fixing screws are installed in the mounting holes. Stormwater pipes are connected to both outer walls of the stormwater well. The drainage device is installed inside the stormwater pipes and is used to cut off floating debris and accelerate the discharge of stormwater. This application uses powered transmission instead of natural discharge to automatically sediment, cut, and transport rainwater in the stormwater pipes to urban rivers, achieving timely, rapid, safe, and efficient drainage of rainwater in the stormwater pipes. This avoids or reduces the occurrence of urban flooding or waterlogging disasters caused by slow flow rates and long emptying times in flood control and drainage stormwater pipes.
