Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The optical device in wireless rotary generator rotor grounding detection apparatus is prone to pollution due to dust accumulation, leading to reduced detection precision and sensitivity, with existing cleaning methods being manual and inefficient.
Innovation Solution
A positive and negative wind pressure automatic cleaning method is employed, where an optical device at the end of a rotor is positioned in a pit structure with airflow from a fan creating a jet effect that alternates between negative and positive pressure areas, causing dust particles to vibrate and be carried away by airflow, eliminating the need for manual cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual cleaning method is used, then the optical device can be cleaned periodically, but the detection precision and sensitivity are influenced due to dust accumulation between cleaning cycles
Solution Approach 1:
The optical device performs self-cleaning through the vibration of dust particles caused by alternating positive and negative wind pressure during rotor rotation, eliminating the need for external manual cleaning operations and maintaining detection precision continuously
Solution Approach 2:
The rotor rotation creates periodic alternating positive and negative pressure zones that continuously vibrate dust particles off the optical device surface, providing continuous cleaning action during operation rather than periodic manual cleaning
2Reliability
If a plane transparent cover is installed to block dust, then dust accumulation on the optical device is prevented, but the structure complexity increases and the cover itself accumulates dust requiring manual cleaning
Solution Approach 1:
The patent removes the transparent cover structure entirely and instead uses the rotor rotation itself to generate cleaning airflow that directly acts on the optical device, simplifying the structure while maintaining dust protection through active cleaning
Solution Approach 2:
The optical device cleans itself through the wind pressure generated by rotor rotation, eliminating the need for external protective covers and their associated maintenance requirements
3Measurement precision
If manual cleaning is performed regularly, then dust accumulation is removed, but the system requires shutdown and manual intervention, reducing operational efficiency
Solution Approach 1:
The cleaning action occurs continuously during rotor rotation through alternating wind pressure zones, maintaining detection accuracy without interrupting system operation or requiring manual intervention
Solution Approach 2:
The system cleans itself automatically during normal operation through the vibration effect of rotating wind pressure, eliminating the need for shutdowns and manual cleaning operations

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method ensures continuous automatic cleaning of the optical device, enhances detection precision and sensitivity, reduces dust accumulation, and prolongs the service life of the optical device by minimizing light loss and maintaining surface cleanliness.
Implementation Method 1
when the airflow passes through the edge of the pit structure at the end of the rotor, a jet effect is formed
Implementation Method 2
due to the entrainment of the jet, the air which is still on the leeside is carried away by the entrainment
Implementation Method 3
the force direction of dust particles on a surface of the optical device continuously and alternately changes positively and negatively at high speed, so that the dust particles are caused to vibrate
