In order to avoid accidents caused by ships colliding with bridges, a large number of bridge anti-collision facilities have emerged.
[0003] Most of the current bridge pier anti-collision devices are placed with a ring of floating balls outside the bridge pier. The floating balls are made of flexible materials, so that the impact force of the ship colliding with the bridge pier is buffered, thereby protecting the bridge pier. At the same time, the floating balls float on the water surface, so that the floating balls rise and fall with the water surface.
[0004] However, the current floating balls are soaked in water for a long time, and the flexibility of the flexible material is reduced after long-term soaking, thereby reducing the protection capability of the bridge pier. CONTENT OF THE INVENTION
