Electronic Well Lid with Anti-Deviation and Garbage Collection Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing well lids pose safety risks during waterlogging events as they can deviate or open, allowing pedestrians to fall into wells, and do not efficiently manage drainage, leading to waterlogging and blockages.
Innovation Solution
An electronic well lid with electric control travel switch, anti-deviation, and garbage collection mechanisms, featuring a well seat with splined connection, sliding ring, and monitoring controller for wireless communication, which includes a well lid lifting mechanism, anti-deviation mechanism, and garbage collection mechanism to ensure safe passage and efficient drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the well lid is opened for drainage during waterlogging, then drainage efficiency is improved, but pedestrian safety deteriorates due to risk of falling into wells
Solution Approach 1:
The well lid is divided into a fixed ring and a movable lid portion, allowing the lid to be segmented for controlled opening and closing while maintaining structural integrity and safety during drainage operations
Solution Approach 2:
A control system with sensors and actuators serves as an intermediary between the drainage need and the well lid operation, enabling automated or remote control of the lid to improve drainage efficiency while maintaining pedestrian safety through controlled access
2Reliability
If the well lid is kept closed to ensure pedestrian safety, then pedestrian safety is improved, but drainage efficiency deteriorates during waterlogging events
Solution Approach 1:
The well lid transitions from a static closed state to a dynamic system that can open and close based on real-time conditions, allowing it to remain closed for safety while opening efficiently when drainage is needed, thus resolving the contradiction between safety and drainage productivity
Solution Approach 2:
Sensors detect water level and flow conditions, providing feedback to the control system which automatically adjusts the well lid state, ensuring pedestrian safety while enabling timely drainage operations when waterlogging occurs
3Device complexity
If traditional mechanical switches are used for control, then device complexity is reduced, but reliability deteriorates due to water and dust exposure
Solution Approach 1:
Traditional mechanical switches are replaced with non-contact sensors (such as infrared or capacitive sensors) that detect well lid position and water conditions without physical contact, eliminating the reliability issues caused by water and dust exposure while maintaining acceptable system complexity
4Ease of manufacture
If the well lid structure is simplified, then ease of manufacture is improved, but anti-deviation capability deteriorates under water pressure
Solution Approach 1:
Counterweights or balancing mechanisms are integrated into the well lid structure to counteract water pressure forces, preventing deviation while maintaining a relatively simple overall structure that remains easy to manufacture

AI summary
An electronic well lid based on electric control travel switch control relates to the technical field of electronic well lids. The electronic well lid based on electric control travel switch control includes a well seat in splined connection with a sliding ring. The sliding ring is provided with a well lid lifting mechanism. A garbage collection mechanism is arranged on the well seat. An arc-shaped groove is formed in the sliding ring. An anti-deviation mechanism is arranged in the arc-shaped groove of the sliding ring. Square grooves are communicated with square holes by way of arrangement of the well lid lifting mechanism and cooperation of first fixing rings and the square grooves. Thus, a drainage speed of the device is increased, pedestrians may continue to pass safely on the well lid in a drainage process of the device, and the protection effect for pedestrians in the drainage process is improved.
