Pivoting Conductor Cleaning Brush for Lineman Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical conductors at connection points often suffer from corrosion and dirt, leading to poor connections and safety hazards for linemen when using standard wire brushes for cleaning.
Innovation Solution
A conductor cleaning brush that can be attached to a hot stick and adapts to the shape of the conductor, featuring pivotally connected arms and flexible wire pads that move from a non-use to a use position to effectively clean the conductor's periphery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard wire brush is used to clean the conductor, then the cleaning action is simple, but the cleaning quality is poor and safety hazards occur
Solution Approach 1:
An insulated handle is introduced as an intermediary between the operator and the wire brush, allowing the brush to contact the conductor while the operator remains insulated. This resolves the safety hazard while maintaining the simplicity of the cleaning action.
Solution Approach 2:
The wire brush is designed with flexible bristles and an adaptable structure that allows it to conform to the conductor's surface. This dynamic adaptation improves cleaning quality by ensuring full contact with the conductor's periphery, including irregular surfaces.
2Adaptability or versatility
If a rigid wire brush is used, then the structure is simple, but it cannot adapt to different conductor shapes and sizes
Solution Approach 1:
The wire brush incorporates flexible bristles and a compliant structure that can bend and conform to the conductor's surface. This flexibility allows the brush to adapt to various conductor shapes and sizes without requiring complex adjustable mechanisms.
Solution Approach 2:
The brush structure is designed to be dynamically adaptable, with movable components that respond to the conductor's geometry. This enables the same brush design to effectively clean conductors of varying shapes and sizes.
3Ease of operation
If the lineman climbs to the connection point for cleaning, then direct access to the conductor is achieved, but safety hazards are created
Solution Approach 1:
The insulated handle serves as a protective intermediary, allowing the lineman to operate the cleaning brush from a safe distance while still effectively cleaning the conductor. This eliminates the need to climb to the connection point.
Solution Approach 2:
The manual climbing and direct-hand cleaning method is replaced with a tool-based system where the insulated handle provides both mechanical leverage for cleaning and electrical insulation for safety.
