Non-demountable Vortex Brake with Flushing Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing CO2 content in the atmosphere due to global warming leads to heavier precipitation loads on drainage systems, and existing drainage systems face issues with hydraulic overload, particularly in public areas where vortex brakes are often installed, but there is a challenge in maintaining their functionality when landowners remove them to avoid flooding, and there is a need for a solution that prevents removal while allowing for cleaning.
Innovation Solution
A non-demountable vortex brake with a flushing access and hose connection is integrated into the drainage system, allowing for internal flushing to clear blockages without allowing air pockets to form and compromise the vortex brake's functionality, and the vortex brake is connected to the drainpipe in a way that resists removal while allowing for efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vortex brake is made non-demountable to prevent removal, then the reliability of the drainage system is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The vortex brake is divided into separable functional components: the main brake body that remains fixed in the gully, and a removable cleaning assembly that can be inserted through the flushing access. This segmentation allows the brake to be both secure (non-demountable main body) and maintainable (removable cleaning components).
Solution Approach 2:
The cleaning assembly is nested within the vortex brake structure, accessible through the flushing access hole. The cleaning tools and components can be inserted through this access point and positioned inside the brake chamber for cleaning operations, then removed without disturbing the main brake installation.
2Ease of repair
If the vortex brake is made demountable for cleaning, then the ease of maintenance is improved, but the reliability deteriorates due to potential removal
Solution Approach 1:
The flushing access serves as an intermediary element that enables maintenance operations without requiring removal of the main brake. Through this access point, cleaning tools, water hoses, and other maintenance equipment can be introduced to perform cleaning tasks while the brake remains securely installed.
3Ease of repair
If a flushing access is added for cleaning, then the ease of maintenance is improved, but the device complexity increases
Solution Approach 1:
The flushing access is designed as a multi-functional opening that serves both cleaning purposes and normal vortex brake operation. The same access point allows for water flushing, tool insertion, and maintains the structural integrity of the brake chamber, eliminating the need for separate access mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution prevents landowners from removing the vortex brake, ensures the vortex brake remains functional by allowing internal flushing to clear blockages, and maintains the system's efficiency in managing heavy rain events by preventing air pockets from forming, thus addressing the hydraulic overload issue.
Implementation Method 1
vortex brake with a vortex chamber having a chamber wall with a peripheral inlet opening and a central outlet opening
Implementation Method 2
water is passed through the water supply hose to flush the vortex brake from the inside so that impurities, which will particularly tend to block the inlet to the brake, are flushed away
