AI Technical Summary
In urban environments with high dust levels, photovoltaic panels and photosensitive sensors are prone to accumulating dust and pollutants, leading to a decrease in the energy efficiency of light-controlled streetlights. Existing technologies struggle to effectively maintain the accuracy of light transmittance and light intensity detection.
The system employs a bowl-shaped mounting bracket with an embedded ultrasonic transducer and a directional water collection tank to work together. High-frequency cavitation effect is used to remove dust and oil, ensuring the light transmittance of the photovoltaic panel. The photosensitive surface of the photosensitive sensor is maintained by periodic ultrasonic water washing through a transparent waterproof cover.
This effectively maintains the light transmittance of photovoltaic panels and the light-sensing accuracy of photosensitive sensors, reduces abnormal energy consumption in light-controlled streetlights, and improves the stability and energy-saving effect of the system.
