A bridge anti-collision device

Abstract

The invention discloses a bridge anti-collision device which comprises a bridge deck horizontally placed between bridge piers. Fixing frames are arranged on the peripheries of the bottom ends of the bridge piers, two sides of the fixing frames are vertically connected with fixing plates, anti-collision mechanisms are mounted on the outer sides of the fixing plates and float on a water surface, smooth surfaces are arranged on the peripheries of the fixing plates, the centers of the anti-collision mechanisms penetrate the bridge piers, contact surfaces of the anti-collision mechanisms and the bridge piers are slidably connected with rubber pneumatic bags, the side faces of the rubber pneumatic bags are provided with sliding grooves corresponding to the smooth surfaces, first mounting platesare rectangularly distributed at corners of the anti-collision mechanisms, and first anti-collision balls are arranged on the outer sides of the first mounting plates. By the aid of the rubber pneumatic bags and the sliding grooves, the anti-collision mechanisms can float on the water surface and vertically slide by matching of the sliding grooves and the fixing plates, failure of the anti-collision mechanisms incapable of moving due to water level rise or fall is avoided, and the bridge anti-collision device is strong in applicability.

Description

technical field [0001] The invention relates to the technical field of bridge protection equipment, in particular to a bridge anti-collision device. Background technique [0002] Bridge construction is one of the most important infrastructure projects at present. The bridge is mainly composed of piers and bridge decks. The piers of the cross-water bridge are located in the water body, and passing ships pass between the two piers. However, there are too many uncontrollable factors such as wind force and water current in the course of the boat, so the heading of the boat is different from that of the vehicle, and it is difficult to control the heading of the boat accurately. Lost accurate directional control and crashed into bridge piers, causing damage to bridges and ships. Although ships are equipped with warning devices such as waterway marks and navigation lights when they pass through the bridge hole, due to the unreasonable changes of the bridge to the waterway, and obj...

However, there are too many uncontrollable factors such as wind force and water current in the course of the boat, so the heading of the boat is different from that of the vehicle, and it is difficult to control the heading of the boat accurately. Lost accurate directional control and crashed into bridge piers, causing damage to bridges and ships

Although ships are equipped with warning devices such as waterway marks and navigation lights when they pass through the bridge hole, due to the unreasonable changes of the bridge to the waterway, and objectively, the ships are often greatly affected by environmental climate and hydrological changes. , such as changes in the river bed, wind speed, wind direction, water level, currents, eddies, undercurrents and other uncertain factors that often cause the ship to yaw when passing the bridge hole
