| description | The invention relates to a dual-mode high-speed pipeline type ventilating fan. The brand new structural design is adopted, the design of a double-effect accelerated air supply mechanism is introducedbased on an existing structure of a ventilating pipeline (1), an electric fan is additionally arranged based on a bearing (2) designed and arranged on the inner wall of the ventilating pipeline (1), and meanwhile through cooperation of a driven wheel (3) fixedly connected to a fan outer frame (6) in the electric fan and a driving wheel (4) which is connected through a belt (9), the electric fan can rotate in an inner ring of the bearing (2) under driving of a rotating motor (5); and thus, through cooperation of rotation of motor fan blades (7) in the electric fan, the motor fan blades (7) canrotate at a higher speed in space, a more efficient air driving effect can be achieved aiming at air in the ventilating pipeline (1), and the ventilating efficiency can be effectively improved.
