Dredging Bell with Movable Partition for Turbulence-Free Sediment Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dredging techniques for removing alluvial deposits from water bodies are inefficient due to turbulence, leading to increased volume, time, and cost, as well as the risk of spreading pollution, which often results in undisturbed polluted areas and unused port zones.
Innovation Solution
A device with a bell having an open bottom and a movable partition in its sidewall, allowing for controlled water level management and suction, enabling the bell to move over the bed without stirring up deposits, isolating and removing them along a desired path without turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional dredging techniques are used to remove alluvial deposits, then the deposits can be removed from the water body, but turbulence is created that stirs up and spreads the deposits, increasing volume and pollution risk
Solution Approach 1:
The device segments the water body by using a bell structure with partition means that divides and isolates alluvial deposits into confined sections. The bell can be positioned at different locations and the partition means creates separate compartments, allowing localized removal of deposits without affecting the entire water body, thus preventing widespread pollution.
Solution Approach 2:
The bell structure acts as an intermediary device between the suction means and the alluvial deposits. It provides a controlled interface where deposits can be isolated and removed through the open bottom, mediating the interaction between the suction system and the water body to minimize turbulence and pollution spread.
2Productivity
If conventional dredging techniques are used, then deposits can be removed, but the volume of deposits increases due to water content from turbulence
Solution Approach 1:
The bell structure segments the water body to isolate alluvial deposits in confined sections, preventing turbulence from mixing large volumes of water with the deposits. This localized approach removes only the necessary deposits without incorporating excessive water, reducing the overall volume of material to be disposed of.
3Object-generated harmful factors
If a pipe is lowered to remove alluvial deposits in situ, then turbulence can be prevented, but the pipe diameter must be limited which makes removal time-consuming
Solution Approach 1:
The device employs dynamic elements including movable partition means that can be raised and lowered, and a bell structure that can be positioned and repositioned. The partition means can be moved to different positions within the bell to adapt to varying deposit conditions, allowing efficient removal without turbulence while maintaining operational flexibility to speed up the process.
4Object-generated harmful factors
If the bell technique is used to remove deposits without turbulence, then pollution spread is prevented, but the bell must be raised and moved to each location which is time-consuming
Solution Approach 1:
The device incorporates dynamic partition means that can be moved within the bell structure to isolate deposits at different locations. This allows the bell to maintain its position while the partition means dynamically adapts to different deposit zones, eliminating the need to physically relocate the bell and significantly reducing time loss.
5Object-generated harmful factors
If public bodies leave polluted alluvial deposits undisturbed to avoid pollution spread, then pollution containment is maintained, but port zones cannot be deepened or expanded
Solution Approach 1:
The bell structure with partition means segments the water body, allowing selective removal of polluted alluvial deposits from specific zones while leaving other areas undisturbed. This enables port zones to be deepened or expanded in targeted areas without spreading pollution to unaffected zones, reconciling development needs with pollution containment.
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 allows for efficient and quick removal of alluvial deposits without dilution or spreading pollution, maintaining a low water level to minimize water suction and preventing deposits from moving outside the bell, thus reducing operational time and costs while preserving the integrity of the water body.
Implementation Method 1
suction means to suck up alluvial deposits from the bell
Implementation Method 2
at least a section of the sidewall of the bell is open at the bottom up to a certain height, whereby the opening can be closed by a partition that can be moved between a raised position, whereby the opening is open, and a lowered position, whereby the opening is closed
