The invention relates to an intelligent surveillance camera automatic cleaning system. The intelligent surveillance camera automatic cleaning system comprises a mounting column and a cleaning device.A mounting plate is disposed at the right end of the mounting column, and mounting holes are symmetrically formed in the mounting plate on the mounting column. A square groove is formed in the left end of the mounting column, and the cleaning device is installed at the left end of the mounting column. The cleaning device includes a cleaning motor, a cleaning rotating shaft, a rotating shaft connecting plate, a cleaning rotating plate, a cleaning base, a cleaning mechanism, positioning mechanisms, stable push rods, stable clamping jaws, a stable connecting plate and a clamping claw angle push rod. The positioning mechanisms comprise positioning support blocks, positioning push rods, positioning connecting frames, extruding plates, extruding push rods, positioning sliding columns, positioning springs, positioning clamping plates and limiting rods. The intelligent surveillance camera automatic cleaning system can solve the problems that the camera cleaning difficulty is high, the manual cleaning effect on a camera is poor, the camera is swayed when the camera is cleaned, and the camera cannot be limited when the camera is cleaned during existing camera cleaning.
