Dynamic anti-collision device of bridge pier

Abstract

The invention discloses a dynamic anti-collision device of a bridge pier. The dynamic anti-collision device of the bridge pier comprises a plurality of buoyancy tanks surrounding the outer side of thebridge pier in a sleeving manner, and steel wire ropes or steel belts bundled on the periphery of the buoyancy tanks and used for connecting the buoyancy tanks into one. A shell of each buoyancy tankis an arc body in the whole, an energy absorbing material is filled inside the shell, a plurality of rolling bodies are arranged on the inner surface of the shell, a blade mounting groove is arrangedin the outer arc surface of the shell in the tangential direction, a blade is mounted in the blade mounting groove in a hinging way through pins, and the blade can be dynamically switched between thefit and unfolded statuses. According to the invention, part of the buoyancy tanks is always exposed above the river surface to protect the appropriate part of the bridge pier regardless of whether the river water rises or falls. The buoyancy tanks can be adaptively adjusted up and down along the bridge pier as the water surface of the riverway changes, which solves the problem that the height adjustment cannot be achieved by taking protection measures in the existing protection system.

Description

technical field [0001] The invention relates to the technical field of bridge safety protection, in particular to a bridge anti-collision device suitable for the technical field of river and waterway bridge safety. Background technique [0002] Due to the vigorous development of the economy and transportation, more and more bridges are erected on the navigable waterway, and the bridges are getting bigger and bigger. There are also super-long sea-crossing or island-connecting bridges, which make the original waterway smaller. narrowed. Therefore, on newspapers or televisions around the world, incidents of ships colliding with bridge piers have occurred and reported from time to time. Some small collisions can also be repaired. Once a large collision occurs, the consequences are unimaginable. In order to make the boat safe and the bridge not damaged, people have taken many methods and facilities to protect the safety of the bridge. [0003] For this reason, domestic and fore...

AI Technical Summary

Problems solved by technology

In the rainy season, when the water level of the river rises, the protective structure is submerged, which is not conducive to the crew to observe the position of the protective structure, which is likely to cause accidental collisions and potential safety hazards. In the dry season, there are excessive exposures, which are not beautiful enough, and can not easily cause collisions on the side of the ship. effective protection of the

[0009] The above-mentioned safety protection measures for bridge piers are static and passive protection. In the human visual system, the sensitivity to stationary objects is low, such as bridge piers, which are not easy to be noticed, and the occurrence of impact events caused by them cannot effectively remind the past Vessels pay attention to navigation safety
