Insulating Protective Cover Closure Interlock for Flow Battery Conveyors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are at risk of electric shock when passing by an exposed conductive part of a live apparatus if the insulating protective cover is not installed in place or is not restored in time after being removed in flow battery energy storage systems.
Innovation Solution
An insulating protective mechanism is introduced, comprising a frame, an insulating protective cover, a transmission assembly, a sensing assembly, and a control unit. This mechanism monitors the closure of the installation space and controls the insulating protective cover to open or close, ensuring the protective cover is always in place before the system is activated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an insulating protective cover is installed outside the motor to prevent electric shock, then safety is improved, but the device complexity increases and the ease of operation deteriorates because the cover must be manually installed and monitored
Solution Approach 1:
The insulating protective cover is designed to automatically close and lock when the motor housing is assembled, eliminating the need for manual installation. The cover integrates with the housing structure such that normal assembly operations automatically engage the protective cover, making the system self-protecting without requiring additional manual steps.
Solution Approach 2:
The insulating protective cover is merged with the motor housing structure, where the cover becomes an integral part of the housing assembly. The cover and housing are designed to work together as a unified structure, with the cover automatically positioning itself during housing assembly, thereby reducing device complexity while maintaining safety.
2Reliability
If an insulating protective cover is used, then electric shock protection is improved, but the ease of operation worsens because users must ensure the cover is properly installed and restored
Solution Approach 1:
The system automatically monitors the status of the insulating protective cover through integrated sensors that detect whether the cover is properly closed. This automatic monitoring eliminates the need for users to manually check or remember to restore the cover, making the system self-monitoring and significantly improving ease of operation while maintaining electric shock protection.
Solution Approach 2:
The control system receives feedback from sensors that detect the position and closure status of the insulating protective cover. Based on this feedback, the control system can automatically determine whether the motor housing is properly assembled and whether safety conditions are met, eliminating manual verification steps and improving ease of operation.
3Ease of repair
If the insulating protective cover is made removable for maintenance, then ease of repair is improved, but safety deteriorates because the cover may not be restored properly
Solution Approach 1:
The control system uses sensors to provide feedback on whether the insulating protective cover is properly closed after maintenance activities. This feedback mechanism ensures that even though the cover is removable for ease of repair, the system automatically verifies proper reinstallation before allowing operation, thereby maintaining safety while preserving ease of repair.
Solution Approach 2:
The system performs preliminary verification through sensor detection before allowing the motor to operate, ensuring that the insulating protective cover is properly closed. This preliminary check prevents operation with an improperly installed cover, maintaining safety while allowing easy removal for maintenance when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The insulating protective mechanism effectively reduces the risk of electric shock by ensuring the insulating protective cover is always closed before the system is operational, thereby preventing live operation of the apparatus without proper shielding.
Implementation Method 1
a sensing assembly, configured to monitor whether the installation space is closed

AI summary
Embodiments of the present disclosure disclose an insulating protective mechanism, a conveying apparatus, and a flow battery energy storage system, which relate to, but are not limited to, insulating protection technology. The insulating protective mechanism comprises a frame, an insulating protective cover, a transmission assembly, a sensing assembly, and a control unit. The insulating protective cover is arranged on the frame, and can enclose with the frame an installation space for installing a conveying mechanism. The control unit controls the transmission assembly to facilitate driving the insulating protective cover to open or close the installation space, so as to facilitate maintenance and replacement of the conveying mechanism in the installation space, and reset the insulating protective cover after the maintenance and replacement of the conveying mechanism. The sensing assembly can monitor whether the installation space is closed, to prevent the conveying apparatus and the flow battery energy storage system from being turned on when the insulating protective cover is not closed, thereby reducing a risk of electric shock.
