Terminal Block Power Distribution for Mining Lamps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In underground mining, the existing control devices for electrohydraulic support controllers require multiple intrinsically safe power supply units for lamps and individual controllers, leading to excessive wiring and complexity, as they use separate power supply units for lamps and controllers, which is inefficient and increases the risk of explosion hazards.
Innovation Solution
A modified terminal block design that integrates power distribution for both lamps and individual controllers using a single intrinsically safe power supply unit, where the terminal block includes an additional fastener for connecting the lamp and features a current-conducting connecting plug, allowing power to be supplied through the same power supply unit for both the controllers and lamps, and includes connectors for tubular cables to facilitate communication and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power supply units are used for lamps and individual controllers, then the reliability of power supply is improved, but the device complexity and wiring work increase
Solution Approach 1:
The patent combines the power supply for lamps and individual controllers into a single integrated power distribution system. The terminal block is modified to include additional fasteners and current-conducting connecting plugs that enable both lamps and controllers to be powered through the same power supply unit, thereby reducing the number of power supply units and wiring complexity while maintaining reliable power distribution.
Solution Approach 2:
The terminal block is designed with multi-functionality to serve both power distribution and signal communication functions. By incorporating additional fasteners and current-conducting connecting plugs into the terminal block, it can simultaneously handle power supply for lamps, power supply for controllers, and data communication, eliminating the need for separate wiring systems.
2Object-affected harmful factors
If multiple intrinsically safe power supply units are deployed, then the safety in underground mining is improved, but the number of power supply units and wiring complexity increase
Solution Approach 1:
The patent merges multiple intrinsically safe power supply units into a single power supply unit that can safely power both lamps and individual controllers. The terminal block is modified to include current-conducting connecting plugs that enable this integrated power distribution while maintaining intrinsically safe operation, thereby reducing the number of power supply units needed while preserving safety.
3Reliability
If separate line systems are used for lamp power supply and controller power supply, then the power distribution reliability is improved, but the wiring work and installation time increase
Solution Approach 1:
The terminal block is designed with universal functionality to handle both power distribution and signal communication through the same interface. By incorporating additional fasteners and current-conducting connecting plugs, it can simultaneously distribute power to lamps and controllers while enabling data communication, thereby reducing installation time and wiring work while maintaining reliable power distribution.
4Ease of manufacture
If a modified terminal block with additional fasteners is used, then the wiring work is minimized, but the manufacturing complexity increases
Solution Approach 1:
The patent merges multiple functions into the terminal block by adding current-conducting connecting plugs and additional fasteners. This integration allows the terminal block to handle power distribution for both lamps and controllers, as well as signal communication, through a single component, thereby simplifying wiring and installation while the increased functionality is managed through standardized design practices.
