All-dielectric Optical Cable Baffle Plate for Animal Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
ADSS optical cables in power systems are vulnerable to damage from small animals like squirrels and mice, which affects their service life and the stability and safety of the power grid due to complex terrains and frequent animal bites.
Innovation Solution
An all-dielectric self-supporting ADSS optical cable line protective device featuring a positioning mechanism with a baffle plate and fastening system that prevents animals from climbing and biting by securely mounting to the cable via a positioning sleeve and using spines and notches for enhanced stability and prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective device is added to prevent animal damage, then the service life and safety of the optical cable is improved, but the device complexity increases
Solution Approach 1:
The protective device is divided into multiple independent components: a positioning mechanism with upper and lower positioning blocks, a protective mechanism with upper and lower baffle pieces, and fastening components. This segmentation allows each component to perform its specific function independently while simplifying the overall assembly and installation process.
Solution Approach 2:
The positioning mechanism and protective mechanism are nested together, with the baffle plate mounted on the positioning sleeve. The upper and lower positioning blocks are positioned within the overall structure, creating a compact integrated device that reduces space occupation while maintaining functional complexity.
2Object-affected harmful factors
If spines are densely arranged on the baffle plate to prevent animal climbing, then the protective effect is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Spines are densely arranged only on specific local areas of the baffle plate - specifically on the arcuate edges of the upper and lower baffle pieces - rather than uniformly across the entire surface. This localized application of spines provides effective animal deterrents at the critical climbing contact points while reducing overall manufacturing complexity and precision requirements.
3Device complexity
If the positioning mechanism and protective mechanism are integrated, then the device complexity is reduced, but the adaptability to different cable positions decreases
Solution Approach 1:
The positioning blocks are designed with movable and adjustable features, allowing them to be positioned at different locations along the optical cable. The fastening mechanism enables dynamic adjustment of the device to accommodate various cable diameters and mounting positions, providing adaptability while maintaining an integrated simple structure.
Solution Approach 2:
The integrated positioning and protective mechanism is designed to perform multiple functions: positioning the device on the cable, securing it firmly, and providing animal protection. The same structural components serve both positioning and protective roles, reducing overall device complexity while maintaining versatility through proper design of the positioning blocks and fastening systems.
