Medium wave infrared detector with cleaning function

The utility model discloses a medium wave infrared detector with a cleaning function, and relates to the technical field of infrared detectors. Comprising a mounting frame and a medium-wave infrared detector body, a rotating rod is rotatably connected between the inner walls of the two sides of the mounting frame, a motor is fixed to one side of the mounting frame, and the output end of the motor penetrates through the mounting frame and then is fixed to the end of the rotating rod. Compared with the prior art, dust is prevented from being directly attached to the surface of the medium-wave infrared detector body through the arrangement of the protective cover, when the protective cover needs to be cleaned, the motor drives the rotating rod to rotate, the rotating rod drives the connecting rod to rotate, and then the medium-wave infrared detector body is driven to rotate to adjust the angle for detection. When cleaning is needed, the motor drives the medium-wave infrared detector body to rotate into the mount
