Venturi Pump Flood Barrier for Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flood defense systems face challenges in allowing effective drainage during flood conditions due to water height differentials between rivers and tributaries, leading to localized flooding and soil contamination, as conventional pumping solutions are expensive and complex.
Innovation Solution
A flood barrier equipped with a venturi effect pump that utilizes the flow rate of water in a drain to create suction, allowing water to be transferred from a tributary to a drain without the need for active pumping under normal conditions, while being energy-efficient and low-maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pumping installations are used to overcome water height differential, then water can be pumped from tributary to drain, but cost and device complexity increase significantly
Solution Approach 1:
The system uses the kinetic energy of flowing drain water to drive the venturi pump, making the pump self-powered without external electricity or fuel supplies. The flowing water automatically creates suction to draw tributary water through the barrier, eliminating the need for external power sources and reducing installation complexity in remote areas
Solution Approach 2:
The invention employs a venturi pump that utilizes hydraulic principles - the flowing water from the drain creates a pressure differential through the venturi effect, generating suction to draw water from the tributary side through the barrier. This hydraulic approach replaces complex mechanical pumping systems with a passive fluid dynamics-based solution

3Ease of operation
If passive barrier is used under normal conditions, then maintenance requirements are reduced, but water transfer capability is lost when height differential is absent
Solution Approach 1:
The system transitions from a static passive barrier to a dynamic system where the venturi pump activates automatically when sufficient water flow is present in the drain. The pump's suction capability varies dynamically with flow rate, enabling the barrier to adapt between passive and active modes based on environmental conditions
Solution Approach 2:
The system uses the kinetic energy of flowing drain water to drive the venturi pump, making the pump self-powered without external electricity or fuel supplies. The flowing water automatically creates suction to draw tributary water through the barrier, eliminating the need for external power sources and reducing installation complexity in remote areas
