In the new energy industry, wind power installation is increased year by year, and wind turbine tower collapse accidents also happen occasionally. The method is characterized in that various tower falling accident reasons are comprehensively analyzed, except for instantaneous tower falling caused by external forces such as extreme meteorological factors, the tower falling of most tower-shaped structures has a process from inclination to tower falling, which is a process of accumulation of inclination amount, the stress of a tower structure and a foundation is gradually increased along with the gradual increase of the inclination angle, and the tower falling accident happens after the stress limit of the structure or the foundation is exceeded. The tower collapse prevention alarm device can send out an alarm by monitoring the inclination state of the tower, and sends out an alarm signal when the inclination of the tower reaches a danger threshold.
