Bridge pier-ship collision monitoring system

Abstract

The invention relates to a bridge pier-ship collision monitoring system, and belongs to the field of bridge monitoring and protection. The bridge pier-ship collision monitoring system comprises a plurality of self-sensing rubber fenders mounted on piers and a monitoring main box; and each self-sensing rubber fender is composed of rubber and a rubber-based collision sensor fixed thereto, wherein the body of the rubber-based collision sensor is an electrode assembly composed of an upper electrode, a lower electrode and a rubber-based quantum tunneling effect composite material therebetween. Thesystem analyzes the area where the sensor electrical signal is different from the normal value when accidents occur by partition arrangement of the self-sensing rubber fenders around the piers, can accurately locate the ship-bridge collision, judge the damage condition of the bridge pier, and provide convenience for the follow-up work of the accident. During the working, the self-sensing rubber fenders can buffer the energy of the bridge-ship collision and protect the structure of the piers. When not in operation, the system is in an open-circuit state, thereby having the advantage of energy saving.

Description

technical field [0001] The invention relates to a bridge pier ship collision monitoring system, which belongs to the field of bridge monitoring and protection. Background technique [0002] With the rapid development of my country's transportation and shipping, there are more and more long-span bridges and large-tonnage ships, and frequent collision accidents between bridge piers and ships pose a huge hidden danger to the social economy and the safety of people's lives and property. To solve this problem, we need to start from two aspects: one is to install protective devices around the piers, such as rubber fenders, artificial islands, piles, etc. Among them, rubber fenders are widely used because of their excellent buffering and energy dissipation effects on ship impacts, low cost, and easy construction and maintenance. However, these traditional pier protection devices cannot effectively locate and assess impacts. On the other hand, Structural Health Monitoring (SHM) is ...

AI Technical Summary

Problems solved by technology

These sensing devices often consume a lot of energy, are expensive, have high maintenance costs, and work poorly in harsh environments (rain, snow, fog)

In addition, the arrangement of these sensing devices needs to occupy part of the waterway, but it cannot buffer the energy dissipation of the impact to protect the safety of the bridge pier structure, and cannot perform damage assessment on the impact
