Remote Cam-Lock Coupling Actuator with Discharge Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized water distribution systems face challenges with low-flow conditions and extended water residence times, leading to water quality issues such as disinfectant residual loss, disinfection by-product formation, bacteria growth, and taste and odor complaints, requiring periodic flushing, but existing flushing devices need excavation for maintenance and are prone to water spray damage during disconnection.
Innovation Solution
A remotely actuated cam-lock coupling system with a discharge containment shroud, allowing for remote coupling and decoupling of flushing devices from pressurized systems using hand levers or motors, and containing the water spray during disconnection to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manually actuated valves and flushing devices are installed in pressurized water distribution systems, then water quality can be maintained through periodic flushing, but excavation is required for maintenance and repair
Solution Approach 1:
The flushing device is segmented into modular components including a valve assembly, cam-lock coupling, and discharge containment device that can be independently accessed and maintained. The above-ground positioning separates the maintenance-accessible components from the underground pipeline system.
Solution Approach 2:
The cam-lock coupling acts as an intermediary connection between the underground pressurized water system and the above-ground flushing device. This intermediate coupling mechanism enables easy connection and disconnection without requiring excavation of the main pipeline.
2Ease of repair
If flushing devices are disconnected from pressurized water systems, then maintenance and repair can be performed, but powerful radially directed water spray is emitted causing damage
Solution Approach 1:
The discharge containment device is pre-positioned and integrated with the cam-lock coupling before disconnection occurs. When the coupling is unlocked, the containment device is already in place to capture and redirect the discharged water, preventing spray damage to surrounding areas.
Solution Approach 2:
The harmful radially directed water spray is converted into a controlled, contained discharge flow. The containment device captures the potentially damaging spray and redirects it through a controlled path, transforming a harmful effect into a manageable discharge process.
3Ease of operation
If remote actuation is implemented for cam-lock coupling, then maintenance can be performed without excavation, but device complexity increases
Solution Approach 1:
The manual mechanical actuation of the cam-lock coupling is replaced with remote actuation mechanisms such as electric motors, pneumatic actuators, or hydraulic systems. This substitution eliminates the need for physical access to the coupling mechanism while reducing the mechanical complexity of manual operation.
Solution Approach 2:
The remote actuation system enables the flushing device to be operated and maintained without requiring physical intervention at the device location. The system can be controlled remotely through automated or distance-based mechanisms, reducing the need for on-site manual operation.
