Vehicle-Road Street Lamp Camera Rotation and Self-Cleaning

The patent applies the dynamics principle by making the camera rotatable around the lamp pole through a rotating mechanism. The camera can dynamically adjust its shooting angle to track running vehicles, transforming from a static fixed camera to a dynamic adjustable camera system. This resolves the contradiction by enabling accurate vehicle capture while maintaining reasonable structural complexity through a focused rotational degree of freedom.

The patent applies the self-service principle by equipping the street lamp with an automated cleaning mechanism that can clean its own lamp surface. The cleaning device includes a cleaning brush that can be extended and retracted to clean the lamp without requiring manual intervention. This eliminates safety hazards associated with manual high-altitude cleaning while keeping the added complexity minimal and integrated into the lamp structure.

The automated cleaning mechanism enables the street lamp to clean itself automatically, significantly improving cleaning efficiency from manual low-speed operations to automated high-speed operations. The cleaning brush can quickly traverse the lamp surface, and the system can be controlled to clean at optimal intervals, transforming cleaning from a labor-intensive periodic task to an efficient automated maintenance function.
