Rotatable Filter Cage for Shallow Water Pumping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid pumping systems face challenges in efficiently pumping water from bodies like rivers and lakes, especially in shallow depths and with varying fluid currents, while also dealing with debris and the need for a simple, mobile, and adaptable solution that prevents fluid backflow and disruption of the water body.
Innovation Solution
A horizontally rotatable fluid pumping apparatus with a pump hose, a rotatable filter cage, and a fluid injection pipe that allows for simultaneous fluid pumping and debris filtration, featuring a check valve to prevent backflow and a conical inlet to manage fluid flow, enabling efficient operation in shallow waters and turbulent conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional pumping system is used to pump water from rivers or lakes, then the pumping function is achieved, but the system disrupts sand or silt at the bottom of the water body and allows debris to enter the pump
Solution Approach 1:
The pump intake assembly is segmented into multiple functional components: a conical inlet structure that directs flow, a filter cage that separates debris, and a screened intake that prevents particle entry. This segmentation allows each component to address specific harmful factors while maintaining overall pumping productivity.
2Adaptability or versatility
If the pump operates in shallow water with varying fluid currents, then the pump can access more locations, but the pump intake becomes unstable and clogs with debris
Solution Approach 1:
The pump intake assembly incorporates a floatation device that dynamically adjusts the vertical position of the pump based on water depth. The assembly can rise and fall with varying fluid levels, maintaining optimal intake positioning. The conical inlet design also dynamically adapts to fluid currents by directing flow smoothly into the pump, preventing clogging while operating in shallow, variable conditions.
3Object-affected harmful factors
If a filter system is added to remove debris, then debris filtration is improved, but the system complexity and risk of clogging increase
Solution Approach 1:
The filter cage and screened intake are merged into a single integrated assembly with the pump housing. The filter cage surrounds the pump intake, and the screen is incorporated into the inlet structure, creating a unified filtration system. This merging provides effective debris removal while maintaining relatively simple construction and ease of maintenance.
4Productivity
If the pump operates continuously in debris-containing water, then pumping productivity is maintained, but the pump components wear and clog over time
Solution Approach 1:
The filter cage and screened intake perform preliminary filtration of debris before water enters the pump components. By removing leaves, branches, and other particulate matter in advance, the system prevents clogging and wear of internal pump components, enabling continuous operation while maintaining reliability.
5Ease of operation
If a mobile pump unit is used for easy installation, then ease of operation is improved, but the pump stability in varying current conditions deteriorates
Solution Approach 1:
The pump assembly incorporates a floatation device that provides buoyant support, counteracting the forces of varying fluid currents. This anti-weight mechanism stabilizes the mobile pump unit in the water, preventing it from being displaced or overturned by currents while maintaining ease of installation and mobility.
