Movable Plug Cover Arm for Arc-Safe Shore Power Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply devices for ship berthing docks pose a risk of arc ignition and explosion due to high-voltage connections between the supplier-side and consumer-side power supply lines, endangering people and flammable articles.
Innovation Solution
A movable arm with a cover part that shields the plug part during connection and disconnection, moving from a covered position to an exposed position to prevent arc ignition, and back to a covered position for safety, is integrated with the displaceable carriage or slide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plug part is exposed for connection to the consumer-side power supply line, then the connection operation can be performed, but arc ignition and explosion risks endanger people and flammable articles
Solution Approach 1:
A cover part is introduced as an intermediary element between the plug part and the surrounding environment. The cover part moves with the arm to expose or cover the plug part as needed, acting as a protective barrier that prevents arc ignition and explosion risks from affecting people and flammable articles while allowing connection operations to proceed when the plug part is exposed.
2Object-affected harmful factors
If the cover part covers the plug part, then protection from arc ignition is provided, but the plug part is not accessible for connection
Solution Approach 1:
The cover part is designed to be dynamic rather than static, moving together with the arm between covered and exposed positions. When the arm moves to the first position, the cover part covers the plug part for protection. When the arm moves to the second position, the cover part exposes the plug part for connection operations. This dynamic behavior allows the system to switch between protection and accessibility modes as needed.

AI summary
The invention relates to a device (1) for supplying a consumer, the position of which initially cannot be exactly determined but later can be substantially stationarily fixed, with energy from a stationary supplier. The device includes a movable carriage or slide (2) connected to an arm (3). The arm (3) is movable between a first position (7) and a second position (8) and the arm (3) includes at least one plug part (4) for connection to an energy supply line (5) of the consumer. The plug part (4) is connected to the supplier by means of an energy supply line (6). A cover part (9), which is movable with the movement of the arm, is arranged on the arm (3). In the first position (7) of the arm (3), the cover part at least partially covers the plug part (4), and in the second position (8) of the arm (3), the cover part exposes the plug part (4) for connection to the energy supply line (5) of the consumer.
