Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting devices for line surge arresters on power towers face difficulties in handling large and heavy units, especially in high-voltage systems, making it challenging to mount them efficiently.
Innovation Solution
A mounting device with a base and joint unit that includes a drive mechanism for pivoting the line surge arrester, featuring a toggle lever configuration and a drive spindle, allowing for manual or mechanical driving to move the arrester from a mounting position to a working position, and a suspension system for securing it in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mounting device without integrated drive mechanism is used, then the device structure remains simple, but the handling and positioning of heavy line surge arresters becomes difficult and time-consuming
Solution Approach 1:
The patent combines the mounting device with an integrated drive mechanism (toggle lever configuration with drive spindle) that is permanently connected to the base and joint unit. This merging allows the heavy line surge arrester to be easily positioned and locked between the toggle levers through mechanical advantage, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The toggle lever configuration acts as an intermediary mechanical system between the operator and the heavy line surge arrester. By using the drive spindle and toggle levers as mediators, the operator can control the positioning of heavy arresters with minimal effort, transforming the direct handling problem into an indirect controlled operation.
2Productivity
If manual handling of heavy line surge arresters is used, then no additional mechanical components are needed, but the mounting process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent employs a dynamic toggle lever configuration that can be easily adjusted between different positions. The drive mechanism allows rapid movement of the line surge arrester from horizontal transport position to vertical operating position, significantly increasing mounting speed while maintaining manageable device complexity through the use of simple mechanical linkages.
3Reliability
If a secure locking mechanism is added to hold the arrester in position, then the reliability of mounting improves, but the device complexity increases
Solution Approach 1:
The toggle lever configuration provides self-locking capability through its mechanical geometry. When the line surge arrester is positioned vertically, the toggle levers naturally lock into place due to the mechanical advantage and geometric constraints, providing reliable mounting stability without requiring additional active locking components or complex control systems.
