Bridge protection anti-collision device

Abstract

The invention discloses a bridge protection anti-collision device, and belongs to the related technical field of bridges. The bridge protection anti-collision device comprises four rectangular hollow blocks and four spline shaft and spline sleeve assemblies, the four rectangular hollow blocks are distributed in a rectangular shape, the water level height is detected through a non-contact water level sensor, a forward and reverse rotation servo motor works in cooperation with a controller and a comparison module. A protection system composed of a rectangular hollow block, a spline shaft and spline sleeve assembly and a protection mechanism moves up and down on the outer surface of a bridge pier through a walking mechanism according to the water level change, and the situation that ships directly collide with the bridge pier to damage the bridge pier is prevented, and the height difference from the protection system to the bottom of a bridge is monitored by a range sensor; a river management center server and a short message sending terminal device are used for sending information and updating height data to a mobile terminal of a ship in real time, a ship driver plans a route in advance according to the height of the ship driver, and the bridge protection anti-collision device can give an early warning in advance, is convenient to install, prevents the bridges and bridge piers from being damaged by collision and has creativity.

Description

technical field [0001] The invention relates to the technical field related to bridges, in particular to a bridge protection anti-collision device. Background technique [0002] With the country's investment in infrastructure, the construction of expressways and bridges has also developed rapidly. When expressways cross mountains, rivers, bays, lakes, reservoirs, irrigation canals and other waters, bridges are generally required to be built. At the same time, bridges are mostly built in On the water surface, there are also some buildings built in valleys or highlands. Or build in urban areas. An important issue that needs to be considered in the design and construction of bridges built across water is to prevent collisions with ships. At present, there are ships in most water areas with relatively large water flows. When ships pass through the gap between two bridge piers, if the ships lose control or the water flow is too turbulent, ship collision accidents may occur. Cu...

Problems solved by technology

In this scheme, anti-collision devices are installed on both sides of the bridge, which are independent of the main structure of the bridge, and can intercept ships on both sides of the bridge facing the pier and whose height exceeds the limited height; it provides all-round protection for the bridge, and the chain It is easy to repair and replace after being damaged, and it also reduces the cost of
