The invention discloses a fixing device for a detection electronic air speed gauge of a mine. The fixing device comprises a bottom plate, a vertical
pipe, a sliding column, a rotating ring, a wind
rudder, a connecting column, a
metal hoop and a
balance shaft, wherein the outer contour of the bottom plate is of a round shape, bottom holes in the
annular array are formed in the bottom plate, the vertical
pipe is welded to the bottom plate, the sliding column is located inside the vertical
pipe, a middle bearing is fixed at the top of the sliding column, a ring column is inserted into the middlebearing, the rotating ring is welded above the ring column, a top bearing is installed inside the rotating ring, the connecting column is located inside the rotating ring, a counter bore and a threaded hole are formed in the connecting column, a threaded part of a rotating bolt is located in the threaded hole, a shaft body of the rotating bolt is located inside the top bearing, the two ends of thebalance shaft are in threaded connection with a
rudder frame and a bent shaft, the wind
rudder is welded on the rudder frame, and the
metal hoop is welded to one end, far away from the threads, of the bent shaft. According to the fixing device for the detection electronic air speed gauge of the mine, the air speed gauge can be always made to face the air flow of an air hole, the
measurement precision is improved conveniently, and the device is suitable for being widely popularized and used.
