Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for river treatment in reservoir areas are inefficient due to the need for regular manual inspection and cleaning of sludge, which can lead to blockages and water quality deterioration, especially during the rainy season when pollutants accumulate and cause eutrophication.
Innovation Solution
A treatment method and system that utilizes a pressure sensor and image acquisition module to automatically detect sludge depth and trigger dredging, combined with nitrogen and phosphorus monitoring and aquatic plant cages to maintain water quality, ensuring timely sludge removal and preventing eutrophication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection and cleaning of sludge is performed regularly, then sludge accumulation can be controlled, but treatment efficiency is low and labor intensity is high
Solution Approach 1:
The system enables self-service through automatic sludge detection and cleaning. The pressure sensor automatically detects sludge accumulation, the lifting mechanism automatically raises the sensor, and the sludge pump automatically removes sludge without requiring manual inspection or operation, thereby resolving the contradiction between cleaning efficiency and manual operation requirement
Solution Approach 2:
The patent replaces manual mechanical inspection with an automated sensing and mechanical cleaning system. The pressure sensor substitutes for manual inspection, and the sludge pump with lifting mechanism substitutes for manual sludge removal, achieving automated operation that improves efficiency while eliminating manual labor requirements
2Reliability
If sludge is not cleaned in time, then river channel blockage occurs and water quality deteriorates, but frequent manual cleaning is inefficient
Solution Approach 1:
The system implements feedback control where the pressure sensor continuously monitors sludge accumulation and provides real-time feedback to the control unit. When sludge reaches a threshold level, the system automatically triggers the lifting mechanism and sludge pump to remove sludge, ensuring timely cleaning while maintaining high efficiency through automated feedback-driven operation
Solution Approach 2:
The pressure sensor performs preliminary detection of sludge accumulation before it causes blockage or water quality deterioration. By detecting sludge early and automatically triggering cleaning operations, the system prevents harmful effects while maintaining efficient, timely sludge removal without requiring frequent manual intervention
3Object-affected harmful factors
If nitrogen and phosphorus concentrations are high, then eutrophication and algae growth occur, but monitoring and treatment requires additional resources
Solution Approach 1:
The system achieves multi-functionality by integrating multiple monitoring and treatment functions into a single unified system. The pressure sensor monitors both sludge accumulation and water quality parameters, the lifting mechanism serves both detection and sludge removal functions, and the sludge pump handles both sludge transport and nutrient removal, thereby preventing eutrophication while avoiding the need for separate complex monitoring systems for each function

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach automates sludge detection and removal, improving river treatment efficiency by ensuring accurate and timely cleaning, and maintaining water quality by controlling nitrogen and phosphorus levels, thus preventing algae growth and maintaining river health.
Implementation Method 1
Moving a pressure sensor arranged at a preset position of the river bottom at a monitoring point upward by a preset distance through a lifting mechanism and sending pressure data collected by the pressure sensor
Implementation Method 2
acquiring an image information of the river bottom within a preset range of the pressure sensor, and sending it to a trained neural network model stored in the data processing module for identification to obtain a depth of a sludge
Implementation Method 3
collecting nitrogen and phosphorus concentration of water body in a river channel, and when the nitrogen and phosphorus concentration exceeds the standard, and when no cages containing aquatic plants are placed in the river channel, putting the cages containing aquatic plants into a river section
