Ocean pier system for protecting ship body by adopting yawing mechanism

Abstract

The invention provides an ocean pier system for protecting a ship body by adopting a yawing mechanism, which belongs to the technical field of overwater building safety protection. The system comprises a pier, ring fixed connection ring rib plates, a connection fixing rotating rod, a fixing nut and anti-collision rotating barrels, wherein three layers of the ring fixed connection ring rib plates are arranged on the outer ring of the pier; a plurality of anti-collision rotating barrels are arranged between every two adjacent ring fixed connection ring rib plates; barrel end plates are respectively arranged at the upper end and the lower end of the anti-collision rotating barrel; and the outermost layer of the anti-collision rotating barrel is provided with a barrel outer wall, and the innermost layer is provided with a barrel inner wall. The system has the advantages that the anti-collision rotating barrel is convenient and fast to install, a single unit is convenient to replace when damaged, the arranged anti-collision rotating barrels can effectively play a role in shock absorption and energy consumption, impact force generated by collision is reduced, and energy exchange and vibration reaction between a ship body and a pier are remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of water building safety protection, in particular to a marine pier system that adopts a yaw mechanism to protect a hull. Background technique [0002] With the continuous development of the transportation industry, a large number of cross-sea and cross-river bridges are constantly being built. Most of the rivers and seas where such bridges are located are busy waterways, and the conditions such as currents, waves, wind and waves are complicated, and the bridge inevitably bears a certain risk of ship collision. Relevant studies have been carried out at home and abroad, and the ship-bridge collision theory has been proposed, and some bridge protection facilities have been designed. The fundamental purpose of bridge anti-collision is to prevent the structural damage of the bridge caused by the collision force of the ship exceeding the design bearing capacity of the bridge pier on the one hand, and to protect ...
