Embodiment Construction

[0029] Below in conjunction with accompanying drawing and embodiment this device is described in detail:

[0030] 1. Overall

[0031] Such as figure 1 , the device includes a power supply A, a current limiting resistor B, a warning light C, a horn D and a monitoring wire E arranged under the bridge;

[0032] The monitoring wire E is connected in series with the power supply A and the current limiting resistor B, and the warning light C and the horn are connected in parallel with the monitoring wire E.

[0033] 2. Functional components

[0034] Power supply A, current limiting resistor B, warning light C and horn D are common parts.

[0035] The monitoring wire E is a commonly used wire. It is set under the bridge and should be straightened and tightened. When the bridge collapses, the monitoring wire E will also break.

[0036] 3. Working principle

[0037] 1. When the bridge is in normal operation

[0038] The monitoring wire E installed under the bridge is in a connect...

Abstract

The invention discloses a method and a device for traffic alarming after a bridge collapses, and relates to a traffic alarming technology. The device comprises a power supply (A), a current limiting resistor (B), a caution light (C), a horn (D) and a monitoring lead wire (E) arranged below the bridge, wherein the monitoring lead wire (E) is connected in series with the power supply (A) and the current limiting resistor (B); and the caution light (C) and the horn (D) are connected in parallel with the monitoring lead wire (E). The method is an effective, quick and practical method for the traffic alarming after the bridge collapses; and the device has the advantages of simple structure, easy implementation and low maintenance cost. The invention can avoid serious accident and heavy casualties caused by vehicles moving on after the bridge collapses, and is applicable to the traffic alarming after all bridge collapse.

Description

technical field [0001] The invention relates to a traffic alarm technology, in particular to a traffic alarm method and device after a bridge collapses, so as to avoid traffic accidents caused by vehicles continuing to move forward. Background technique [0002] Existing bridges are not equipped with equipment that can quickly report to the police after a bridge collapses. When the bridge collapses, especially at night and under conditions of low visibility such as rain, snow, and fog, when the vehicle continues to move forward, it will often cause major traffic accidents such as vehicle damage and casualties. Contents of the invention [0003] The purpose of the invention is to change the current situation of no police after bridge collapse, and provide an effective, rapid and practical traffic alarm method and device after bridge collapse. [0004] The purpose of the present invention is achieved like this: [0005] 1. Traffic alarm method (referred to as method) after...
