Movable type axial flow fan device

The utility model discloses a movable type axial flow fan device which comprises a trolley, axial flow fans, a track, a position sensor, a limit switch, a control line and a power line. The trolley is installed on the track which is provided with the position sensor. The limit switch is installed at the tail end of the track. The trolley is provided with the axial flow fans. The control line and the power line are installed on the two sides of the track respectively. The axial flow fans are arranged on the two opposite sides of a greenhouse, so that even air feeding is achieved, air flow in the whole greenhouse is more uniform, and the adjustment effect of temperature and humidity is better. Meanwhile, the movable axial flow fans are installed on the two opposite sides of the greenhouse, the axial flow fan on one side is used for blowing air and the axial flow fan on the other side is used for pumping air, so that the air in the whole greenhouse flows, and the overall adjustment effect of temperature and humidity is better. In addition, the movable type axial flow fan device is simple in structure, convenient to operate, low in manufacturing cost and good in practical application value.
