AI Technical Summary

Technical Problem

The existing bridge anti-collision-avoiding warning device cannot effectively disperse the impact force of the bridge, resulting in the bridge body still being hit by a large impact.

Method used

A bridge anti-collision-avoiding early warning device is designed. By setting a buffer mechanism outside the beam body, the buffer mechanism includes a connecting rod, a rubber block, a spring and a rubber pad. The impact force is transmitted to the rubber block by using the flexible material characteristics of the rubber block. The rubber block squeezes the spring, and the spring drives the crossbar to slide, disperse the force to the connecting rod, and reduces the impact on the beam body.

Benefits of technology

It effectively disperses the impact force during the impact of the ship, reduces damage to the bridge body, and reminds the driver to avoid impact through the cooperation of laser ranging sensors, buzzers, electronic screens and voice broadcasters.

Abstract

The utility model provides an anti-collision early warning device for a bridge, and relates to the field of early warning devices. The buffering device comprises a beam body, a buffering mechanism is arranged outside the beam body and comprises two connecting rods, the two connecting rods are fixedly installed on the outer wall of the beam body, the interiors of the two connecting rods are both slidably connected with transverse rods, the two ends of the two transverse rods both extend to the exteriors of the connecting rods, and the outer walls of the two transverse rods are both fixedly connected with rubber blocks. The outer walls of the two cross rods are sleeved with springs, the two sides of the two springs are fixedly connected with the corresponding rubber blocks and one side of the connecting rod respectively, and a rubber punching pad is fixedly connected between the two rubber blocks. When a ship collides with the rubber cushion, the rubber cushion is subjected to collision force and extends towards the two sides under the characteristic of the flexible material, that is, the force is transmitted to the rubber blocks on the two sides through the rubber cushion, the two rubber blocks extrude the springs backwards to drive the cross rod to slide towards the two sides, finally the force is dispersed to the connecting rods, and collision to the beam body is reduced.
