Overwater boat collision protecting device

Abstract

The invention relates to an overwater boat collision protecting device used for overwater facilities such as bridges, wharfs, boats, courses and platforms. An anti-collision framework 2 is arranged on the periphery or the edge of the overwater facilities such as bridge pier bearing tables, anti-collision pier bearing tables, wharfs, boats, courses and platforms, and the outer edge of the anti-collision framework 2 is provided with rolling wheel devices 3 or linked rolling wheel devices with mechanical transmission elements 4, wherein the head part 21 of the anti-collision framework is in a streamline shape, and the inner side of the anti-collision framework is provided with a buffer. Compared with the prior art, the overwater boat collision protecting device has the advantages that when a boat collides with the overwater boat collision protecting device, the collided rolling wheel device rotates, the rolling wheel devices are linked, partial kinetic energy of the boat is absorbed, the inclined side surface of a boat head or the side surface of the boat is tangent with the wheel surface of the rolling wheel devices, the tangent counter-acting force pushes the boat to move towards, the navigation direction of the boat is corrected, the side surface of the boat runs along the rolling wheel devices in a rolling way, and most kinetic energy is taken away, so a collided object is protected, and a accident causing boat is also protected.

Description

technical field [0001] The invention relates to a protection technology for ship collision on water, and is mainly used as a protection device for ship collision on water of bridges, wharves, ships, waterways, platforms and other water facilities in sea areas, rivers and lakes, so as to avoid damage caused by ship collision. Background technique [0002] At present, in many bridges, an independent anti-collision pier system is set up upstream and downstream of the channel pier, and the anti-collision pier can be divided into two types: flexible and rigid. Flexible anti-collision piers generally adopt steel pipe piles or steel pipe concrete piles. This kind of anti-collision facilities will undergo large deformation and cause less damage to ships. Rigid anti-collision piers generally adopt prestressed concrete piles or bored piles, which mainly rely on bow deformation to absorb impact energy. The independent anti-collision pier anti-collision system of the ship collision bri...

[0004] Disadvantage: great damage to the ship

[0013] At present, when a ship is driving on the waterway, it deflects unexpectedly, leaves the waterway and enters a non-waterway, goes astray, hits a water facility, hits an offshore oil well platform, hits a rock, or hits a ship, etc.
