Title:
POSITIVE AND NEGATIVE WIND PRESSURE-BASED AUTOMATIC CLEANING METHOD FOR OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/001075
Kind Code:
A1
Abstract:
A positive and negative wind pressure-based automatic cleaning method for an optical device. An optical device (1) located in a recess (3) structure at an end of a rotor (2) is placed in an inlet air duct. When the generator rotor rotates, a fan located on the generator rotor continuously delivers airflow into the inlet air duct. The rotation plane at the end of the rotor is parallel to the flow direction of the airflow. The quick flow of air in the parallel direction forms alternating positive and negative wind pressure on the surface of the optical device in the recess structure of the rotating member to cause vibration of dust particles, thereby achieving automatic cleaning. The method achieves automatic cleaning of the surface of an optical device, and solves the problem of affecting the accuracy and reliability of grounding detection of a rotor due to the accumulation of dust.
