Since the construction of the Three Gorges Reservoir,the waterway conditions have been greatly improved,the flow of ships has increased,and ships have developed to large scale.Traditional navigational aids cannot meet the needs in the new era.This article proposes a new intelligent floating drum structure that can adapt to large water level fluctuations in the Three Gorges Reservoir area.The force process of the floating drum during water level changes is simulated through the dynamic force analysis and construction of a floating drum mechanical model.Based on the above,the intelligent lifting technology is proposed.The application of the intelligent lifting technology and power supply systems of floating drums in the reservoir area are analyzed deeply.The results show that intelligent floating drums can adapt well to the large water level fluctuation in the Three Gorges Reservoir area,and its technical performance runs well.It is suggested that in the future,the promotion and application of intelligent floating drums should be accelerated to meet the navigation assistance needs of the Three Gorges Reservoir area in the new era.
