Description

Technical Field

[0001] The present invention belongs to the technical field related to induction indicating devices, and more specifically, particularly relates to an induction indicating device for emergency response to bridge collapse. Background Art

[0002] As an important part of transportation infrastructure, bridges play a key role in modern transportation. However, the traffic environment on bridges is often complex, with a variety of potential safety risks and traffic guidance needs, which has led to the emergence and development of bridge guidance devices. However, the guidance indicator devices in the prior art have the following defects:

[0003] 1. In the prior art, when the induction indicator device is set on the roadside, it is difficult for the driver to notice the warning device on the roadside, and the driver will miss important road condition information. If the driver does not see the warning light and drives at a normal speed, he may encounter the construction area without any preparation, and will not have time to brake or avoid, thus causing rear-end collision, collision with construction equipment or personnel and other accidents; 2. In the prior art, the luminous angle of the induction indicator device is fixed. When driving on a highway, especially on a multi-lane bridge, the fixed-angle reflection may not cover all lanes, and the driver in the lane far away from the device may not be able to see the indication information, which may cause some drivers to miss important traffic guidance prompts, such as lane changes, speed limit information or warnings of construction ahead; Therefore, in view of this, the existing structure and defects are studied and improved, and an induction indicator device for bridge collapse emergency response is provided, in order to achieve a more practical and valuable purpose.

[0034] Specific use of the present invention: When using the present invention, first install the device at a position more than 200 meters away from the backboard of the bridge, and install it in the green belt in the middle of the road or in the greening on one side. After the installation is completed, connect the device to the external system. After the connection is completed, the device can be put into an all-weather working state. Then, when in use, after the bridge tilts, the background system will control the device through the communication module.

[0035] Then the LED display device 15 partially displays the content for reminder, and then the induction warning horn 17 and the induction warning sign 18 arranged on both sides of the LED display device 15 work, and the induction warning horn 17 starts to make a sound for warning reminder, and the induction warning sign 18 and the lighting spotlight 19 are in operation, the lighting spotlight 19 is in a flashing state, and the induction warning sign 18 will be displayed constantly, and then when the induction warning horn 17 plays the sound for warning, the sound of the induction warning horn 17 will be regulated by the danger level set by the background system.

Then, when the telescopic refraction plate 37 is extended, the light on the reflective panel 27 will be reflected by the telescopic refraction plate 37 again. The refracted light will be reflected to the road surface through the refraction angle of the telescopic refraction plate 37. When a vehicle passes by, the driver's eyes will be dynamically reminded to achieve further reminders.

[0037] And when the frequency value of the induced warning horn 17 is increased to 600-800HZ, the low-hertz tuning forks 29 provided on the left and right sides of the reflective panel 27 will sense the hertz number of the induced warning horn 17 and will resonate synchronously, causing it to fluctuate laterally during the resonance. This lateral fluctuation effect, and when the reflective panel 27 fluctuates laterally, the screen will shake more violently, making it easier to remind the driver to receive the warning information.
