description The utility model relates to the technical field of civil air defense engineering, in particular to a closed observation window in civil air defense engineering, which comprises a sealing window frame and a closed window, a window is arranged in the sealing window frame, an L-shaped groove is arranged on one side and above the window, a conveying mechanism is arranged above the inside of the L-shaped groove, and the closed window is arranged above the conveying mechanism. According to the closed window cleaning device, the smoke state of the outside can be sensed through the arranged smoke sensor, the first motor can be started in time to drive the sliding block to move in the state of a fire disaster, and meanwhile the second motor is started to drive the sliding rod and the cleaning brush to rotate to clean the closed window; meanwhile, the spraying head sprays water flow to soak and clean the cleaning brush, and the situation that the observation window is smoked and dyed by smoke to become black in the fi
