Solution Overview
Problem
Current wave-making pumps produce concentrated and intensive water flow, which is not effective in simulating natural water waves, failing to create an optimal aquatic environment for fish growth and development.
Innovation Solution
A wave-making pump with a novel directional structure, featuring a casing with a diversion protective cover having a hollow groove and reinforcing ribs, combined with a magnetic fixing device, produces a wider, softer, and more uniform water flow, resembling natural ecological waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional wave-making pumps are used, then water flow can be produced, but the water flow is concentrated and intensive, creating a water column shape that is not effective for simulating natural water waves
Solution Approach 1:
The diversion protective cover is divided into multiple sections with different hollow grooves (first, second, third hollow grooves) and reinforced by multiple reinforcing ribs. This segmentation allows the water flow to be distributed into multiple channels, transforming the concentrated water column into a wider, softer flow pattern that better simulates natural water waves.
Solution Approach 2:
The patent introduces a third dimension to water flow distribution by creating hollow grooves that extend along the axial direction of the impeller shaft. This adds a longitudinal dimension to the flow distribution, spreading water flow not only radially but also along the axis, thereby creating a more three-dimensional, natural wave pattern.
2Quantity of substance
If conventional pumps are used, then water flow is produced, but the flow is too concentrated and intensive
Solution Approach 1:
Different regions of the diversion protective cover are given different local qualities through strategically placed hollow grooves and reinforcing ribs. The first hollow groove near the impeller outlet directs flow in one pattern, while the second and third hollow grooves further along the axis create additional flow patterns. This local differentiation ensures water flow is distributed evenly across different regions, preventing concentration and intensification.
Solution Approach 2:
The diversion protective cover acts as an intermediary device between the impeller and the water environment. It intercepts the concentrated water flow from the impeller and redistributes it through its hollow groove structure, transforming the intensive spray into a gentler, more widespread flow that achieves better oxygenation and environmental benefits without the harmful concentrated spray effect.
3Ease of manufacture
If a simple casing structure is used, then manufacturing is easier, but the directional control of water flow is insufficient
Solution Approach 1:
The diversion protective cover incorporates curved hollow grooves that follow the rotational pattern of the impeller. These curved channels naturally guide the water flow in circular or spiral patterns, adapting to the rotational motion of the impeller. This curvature design provides excellent directional control for creating natural wave patterns while maintaining a relatively simple overall structure that is easy to manufacture.
Solution Approach 2:
The diversion protective cover serves multiple functions simultaneously: it acts as a protective cover for the impeller, a flow distribution system with multiple hollow grooves, and a structural reinforcement element with integrated ribs. This multi-functionality allows the single component to provide comprehensive water flow directional control without requiring additional separate parts, thus maintaining ease of manufacture while achieving versatile flow control.

Function Achieved in This Case
The pump creates a water flow that is wider, softer, and more uniform, effectively simulating natural water waves, enhancing the aquatic environment for fish growth and development by increasing oxygenation and microorganism interaction.
Implementation Method 1
a hollow groove helically extending is formed in the peripheral surface of the diversion protective cover
Implementation Method 2
the outer magnetic sucker and the inner magnetic sucker are both provided with a magnet; the outer magnetic sucker and the inner magnetic sucker attract each other to clamp the wall of an aquarium; the ferromagnetic body and the inner magnetic sucker attract each other

AI summary
The utility model provides a wave-making pump with a novel directional structure, comprising a casing, a motor, an impeller and a fixing device, wherein the motor is fixed in the casing; the impeller is arranged at the output end of the motor; the fixing device is used for fixing the casing; the casing comprises a rear casing and a diversion protective cover arranged on the front side of the rear casing; openings are formed in the two ends of the diversion protective cover; a hollow groove helically extending is formed in the peripheral surface of the diversion protective cover. As the hollow groove helically extending is formed in the peripheral surface of the diversion protective cover, the water flow produced by wave-making pump with the novel directional structure is wider, softer and more uniform, and the aquatic environment closer to the natural ecological water wave is convenient to create.
