The invention discloses a tower-shaped mast anti-impact device and a method thereof. A mast base frame is provided a horizontal shaft. The lower part of the mast is hinged with the horizontal shaft. A mast motor which is arranged on the mast engages with a speed reduction gear through a driving gear and an intermediate gear. The mast base frame is provided with a fixed gear which is coaxial with the horizontal shaft. The speed reduction gear engages with the fixed gear. The mast end below the horizontal shaft is provided with a counterweight. The mast base frame is provided with an obstacle detecting device which is used for detecting an obstacle in front of a ship in a navigation direction and an obstacle sensor that is used for detecting the obstacle above the ship. The tower-shaped mast anti-impact device effectively settles a problem of easy impact accident caused by negligence or erroneous judgment in a prior-art mast lifting device. The tower-shaped mast anti-impact device can automatically detect the obstacle and automatically takes the mast down, thereby ensuring high safety in navigation. Furthermore the tower-shaped mast anti-impact device has high use value.
