Systems for automatically removing spider webs and other debris from surveillance camera lenses

摘要

The current document is directed to automated, electromechanical methods and devices that clean dirt, moisture, and spider webs from the lenses of surveillance cameras. In one implementation, a camera-cleaning device comprises a cleaning unit, a freely rotating L-shaped hinge, a geared electric motor, a motor-control circuit for controlling the forward and backward motion of the device, and a time-control circuit for controlling the start, finish and run time of cleaning cycles. The cleaning unit includes a cleaning head and a propeller blade that spins to lift the cleaning unit up from a rest position to a cleaning position and subsequently clean the front of the camera lens. The pivotal L-shaped linkage enables the device to transition between the cleaning position and the rest position.
