Description

Technical Field

[0001] This application relates to the field of bridge monitoring technology, and in particular to a bridge damage warning system. Background Technology

[0002] When a bridge collapses or suffers structural damage, vehicles behind it are often unable to obtain timely information about road conditions ahead, or their drivers react slowly, making secondary accidents highly likely. These secondary disasters not only cause significant casualties and property damage but also expose systemic deficiencies in emergency management of bridge engineering. Data shows that the casualty rate from such secondary accidents is often 37% to 45% higher than that from the initial structural damage. This safety hazard has become a major issue that urgently needs to be addressed in the operation of modern transportation infrastructure.

[0003] Currently, most systems used for bridge disaster monitoring and early warning are intelligent systems that integrate various technologies, with multi-source sensing, intelligent algorithms, and real-time linkage as their core, enabling relatively real-time and accurate post-disaster early warning. However, the application of such technologies is relatively rare in bridges in remote areas and in small and medium-sized bridges, and the application costs are high, making maintenance and repair difficult.

[0057] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] Existing bridge damage warning systems suffer from high costs and are difficult to repair and maintain.

[0059] To solve the above problem, please refer to Figure 1 - Figure 3 This application provides a bridge damage warning system.

[0060] Please refer to Figure 1 - Figure 3In this application, the first direction X is the length direction of the bridge, the second direction Y is the width direction of the bridge, and the third direction Z is the height direction of the bridge.

[0061] Please refer to Figure 1 - Figure 3 The bridge damage warning system includes two mounting plates 100, located at opposite ends of the bridge along a first direction X, and fixed to one side of the bridge along a second direction Y. A warning barrier 200 is mounted on the mounting plate 100 along the second direction Y, with one end hinged to the mounting plate 100. A pin hole 210 is provided on one side of the warning barrier 200 along the first direction X, and a locking pin 300 is slidably connected to the side of the mounting plate 100 along the first direction X. The bridge damage warning system also includes a triggering component 400, which controls the warning barrier 200 to switch from a first state to a second state. The first state refers to the bridge being in a normal traffic condition, where the locking pin 300 is inserted into the pin hole 210, and the warning barrier 200 is positioned along a third direction Z, i.e., the warning barrier 200 is in a vertical state. The second state refers to the following: When the bridge breaks or is damaged, under the action of the trigger component 400, the locking pin 300 separates from the pin hole 210. At this time, without the constraint of the locking pin 300 and the pin hole 210, the warning barrier 200 rotates around its hinge axis with the mounting plate 100. Finally, the warning barrier 200 is positioned along the second direction Y, that is, at this time the warning barrier 200 is placed horizontally on the bridge to warn and prevent vehicles behind from continuing to travel. Because the structure of this application is relatively simple, the subsequent maintenance and upkeep costs are also lower than those of existing warning systems.

[0062] In the instant a bridge breaks or is damaged, this application triggers the component 400 to immediately pull the locking pin 300 out of the pin hole 210, thereby causing the warning barrier 200 to immediately change from a vertical position to a horizontal position on the bridge surface. This allows for timely warning and deterrence of vehicles behind. Overall, this application not only provides timely post-disaster early warning but also has a simple structure and extremely low operation and maintenance costs.

[0063] Please refer to Figure 3 As a specific implementation of the present application, the bridge damage warning system of the present application further includes a first elastic element 500, which is installed between the warning barrier 200 and the mounting plate 100, and the first elastic element 500 always provides a force to the warning barrier 200 to switch from the first state to the second state.

[0064] Specifically, the first elastic element 500 is a compression spring. In the second direction Y, one end of the compression spring is fixed to the mounting plate 100, and the other end of the compression spring abuts against the warning bar 200.

[0065] The following section provides a further explanation based on a specific application scenario. When the locking pin 300 is pulled out, the first elastic element 500 provides a force to the warning barrier 200 away from the mounting plate 100. This allows the warning barrier 200 to immediately rotate around its hinge axis with the mounting plate 100 after the locking pin 300 is pulled out, ensuring the timeliness and reliability of the warning barrier 200's transition from the first state to the second state. The use of a spring as the first elastic element 500 is to further reduce the investment cost of the bridge damage warning system.

[0066] Please refer to Figure 2 and Figure 3 As a specific embodiment of this application, the triggering component 400 of this application includes a plurality of first pulleys 410. These first pulleys 410 are installed on one side of the bridge along the second direction Y, and the plurality of first pulleys 410 are divided into two groups. The two groups of first pulleys 410 are correspondingly arranged in the third direction, that is, the two groups of first pulleys 410 are arranged vertically. The plurality of first pulleys 410 in each group are distributed in an equidistant linear array in the first direction. The triggering component 400 also includes a connecting line 420. The connecting line 420 is disposed between the two groups of first pulleys 410, and the connecting line 420 abuts against both groups of first pulleys 410. The two ends of the connecting line 420 are respectively connected to two locking pins 300 at both ends of the bridge.

[0067] Depending on the specific usage scenario, under normal bridge conditions, the connecting line 420 is in a horizontal state. However, when the bridge breaks or collapses, the entire or part of the bridge tilts. The vertical tilt at the break point will pull the connecting line 420, which in turn pulls the locking pin, causing the locking pin to be pulled out of the pin hole 210.

[0068] For further details, please refer to Figure 3 The triggering component 400 also includes a second pulley 430, which is installed on the side of the mounting plate 100 connected to the locking pin 300. The connecting line 420 passes around the second pulley 430 and is fixed to the locking pin 300. The connecting line 420 of the second pulley 430 and the pin hole 210 is collinear with the axis of the pin hole 210. In this way, when the locking pin 300 is pulled, the direction of the pulling force on the locking pin 300 is exactly collinear with the axis of the pin hole 210, so that the locking pin 300 can be pulled out more smoothly.

[0069] The trigger component 400 of this application has a relatively simple structure and low cost, but it can switch the state of the warning bar 200 in a timely manner. In addition, the first pulley 410 is located on the side of the bridge along the second direction to facilitate the later maintenance and repair of the trigger component 400.

[0070] Reference Figure 3As a specific embodiment of this application, the bridge damage early warning system of this application also includes a tensioning component 600. The tensioning component 600 is used to tension the connecting line 420. The tensioning component 600 includes an auxiliary plate 610 fixed to one side of the mounting plate 100 along the first direction. One end of the second elastic member 620 is fixed to the auxiliary plate 610, and the other end is fixed to the locking pin 300. The second elastic member 620 always provides a force for the locking pin 300 to insert into the pin hole 210.

[0071] Depending on the specific application scenario, the tensioning component 600 ensures that the connecting line 420 is kept taut. Therefore, if the bridge breaks, the resulting tilt and misalignment can immediately pull the connecting line 420, thus ensuring the stability of pulling out the locking pin 300. Furthermore, the second elastic element 620 ensures that when the bridge is not damaged, the locking pin 300 remains firmly inserted in the pin hole 210 without external force, thereby guaranteeing the stability of the warning barrier 200.

[0072] Please refer to Figure 2 and Figure 3 As a specific implementation of the present application, the bridge damage early warning system of the present application also includes a support component 700. In the second direction Y, the support component 700 is correspondingly arranged with the mounting plate 100. In the second state, the end of the warning bar 200 away from the mounting plate 100 abuts against the support component 700.

[0073] Furthermore, the support assembly 700 includes a first support plate 710 fixed to one side of the bridge along a third direction Z, i.e., the first support plate 710 is in a vertical state, and a second support plate 720 fixed to the side of the first support plate 710 along a second direction Y, i.e., the second support plate 720 is in a horizontal state.

[0074] Furthermore, a rubber pad 721 is fixed to the top of the second support plate 720.

[0075] The following describes the specific usage scenario: When the locking pin 300 is pulled out, the warning barrier 200 rotates around its hinge axis with the mounting plate 100. When the warning barrier 200 reaches a horizontal position, the end of the warning barrier 200 away from the mounting plate 100 abuts against the second support plate 720. The second support plate 720 supports the suspended end of the warning barrier 200, making its placement more stable. The rubber pad 721 fixed on the second support plate 720 provides some cushioning against collisions between the warning barrier 200 and the second support plate 720, reducing the degree of hard impact between them.

[0076] As one specific implementation of this application, a reflective strip is affixed to the warning bar 200.

[0077] Depending on the specific usage scenario, the reflective strips can provide a clearer warning to drivers and passengers behind at night.

[0078] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0079] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0080] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
