Description

Technical Field

[0001] The present invention belongs to the technical field related to luminous warning lights, and more specifically, particularly relates to a self-luminous warning light for detecting the inclination of a bridge guardrail. Background Art

[0002] Bridges, as key nodes in the transportation network, carry huge flows of people, vehicles and logistics. Their safe and stable operation is of immeasurable value in ensuring public safety and promoting economic activities. Once a bridge collapse occurs, it often leads to casualties, road damage, vehicle losses, etc. The consequences are disastrous. However, the bridge warning lights in the prior art have the following defects:

[0003] 1. In the prior art, the warning lights on bridges usually only have the functions of lighting and warning when there is a traffic jam. If a bridge collapses or tilts, the simple warning lights do not have the functions of providing warnings and rapid reporting. When an old bridge collapses, the failure to quickly report and provide warnings may lead to serious traffic accidents. 2. In the prior art, when the bridge warning light is working for a long time, the bridge is subjected to continuous vibration generated by the driving of vehicles. The continuous vibration can easily cause the three-axis sensor inside the warning light to misjudge. Frequent false alarms will also make people gradually distrust the signal of the warning light, causing passing vehicles and pedestrians to receive wrong safety prompts, resulting in unnecessary panic. 3. In the prior art, bridge warning lights are simply fixed to the bridge railings with bolts, without taking into account the continuous vibration of the bridge during vehicle travel. Over time, the bolts may gradually loosen, causing the warning light to shift in position or even fall off. This may cause the three-axis sensor of the warning light to misjudge. Once a real bridge safety accident occurs, people may ignore the correct alarm of the warning light, delay taking necessary risk avoidance measures, and increase the severity of the accident.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a self-luminous warning light for detecting the inclination of a bridge guardrail is provided, in order to achieve a more practical and valuable purpose. Summary of the invention

An upper end limit block 49 is provided at the end of the threaded portion 46, and the upper end limit block 49 is used to limit and protect the first bolt 45.

[0036] Specific use of the present invention: When using this device, first install the device vertically on the bridge guardrail, then connect the power supply of the device, and connect the networking function of the device to the Jingshang Bridge Collapse Warning System. After the connection is completed, the device can be used normally.

[0037] During the normal operation of the device on the bridge, the communication module and light sensor equipped with the device will be in normal working state, and the communication module will be in standby state. The light sensor controls the light of the device by detecting light sensitivity, so as to respond to the changes in light sensitivity during the day and night. At the same time, the three-axis sensor set on the inner side of the luminous warning light 13 will detect the angle of the device when working. When the three-axis sensor detects that the angle is normal, the luminous warning light 13 works normally; once the three-axis sensor detects that the angle is abnormal, the luminous warning light 13 will turn on the alarm mode, and start the communication module at the same time, and report the current status of the device to the system background. At the same time, the device will change the light color of the luminous warning light 13 and adjust it to red to serve as a warning. Subsequently, the system background determines whether the luminous warning light 13 at this location is a false alarm. If it is determined to be a false alarm, the staff will repair it; if the staff determines that it is not a false alarm after on-site inspection, the control background will uniformly adjust the luminous warning lights 13 within a straight-line distance of 200 miles to red, and issue an alarm to the passing vehicles.

[0038] Moreover, after the device is installed on the bridge for a long time, the vibration generated by the vehicle driving may cause the three-axis sensor to misjudge, and it is necessary to go to the site manually for judgment, which will greatly increase the labor cost and time cost. However, during the use of the device, when the vibration is transmitted to the light-emitting warning light 13 through the self-expanding bolt 14 and the lower mounting plate 15, the vibration is first transmitted from the lower mounting plate 15 to the extrusion cylinder 21, and the extrusion cylinder 21 will cooperate with the piston rod 23 to perform shock-absorbing extrusion and produce gas. At the same time, the shock-absorbing buffer device arranged on both sides of the extrusion cylinder 21 will also play a shock-absorbing and buffering role. When the vibration is transmitted, the vibration will be buffered by the sliding rod 18 to the upper mounting plate 12, so that the sliding rod 18 forms a buffering effect inside the piston cylinder 24, so that the light-emitting warning light 13 maintains a stable working state, ensuring that the three-axis sensor inside the upper mounting plate 12 is always in a balanced state.

[0039] Furthermore, when the gas generated by the piston rod 23 and the extrusion cylinder 21 during the extrusion process enters the high-pressure chamber 31 through the air pipe, since there is high-pressure gas in the high-pressure chamber 31, the newly entered gas will push the first piston plates 32 on both sides to move outward. When the bridge continues to vibrate, gas will continue to be generated inside the extrusion cylinder 21, and these gases will continue to enter the high-pressure chamber 31. Then the first piston plate 32 will continue to be pushed, thereby driving the first clamping block 35 to move toward the second clamping block 36, which plays a limiting role on the self-expanding bolt 14. At the same time, the gas inside the high-pressure chamber 31 will also enter the extrusion chamber 38 through the air pipe 40. The extrusion chamber 38 will push the extrusion plate 39, so that the extrusion plate 39 drives the second clamping block 36 to approach the first clamping block 35. When the second clamping block 36 and the first clamping block 35 are close to each other and combined into an inner hexagon, the second bolt 48 of the self-expanding bolt 14 will be locked.

[0040] At the same time, when the second clamping block 36 and the first clamping block 35 are squeezed synchronously, the gas inside the high-pressure chamber 31 will also synchronously enter the annular outer chamber 50 of the self-expanding bolt 14, pushing the second piston plate 51 in the annular outer chamber 50 to move downward. When the second piston plate 51 moves in the annular outer chamber 50, it will push the inclined surface block 52 to shrink inward. When the inclined surface block 52 shrinks inward, the front thorn portion 55 set at the other end of the guide block 53 will break the leather rubber ball 56 on the leather bag 57. After the leather rubber ball 56 is broken, the expansion material set inside the leather bag 57 will flow outward through the leather rubber ball 56. The outflowing expansion material will first expand the annular inner chamber. The expanded annular inner chamber will provide additional support for the self-expanding bolt 14. At the same time, the outflowing expansion material will fill the gap between the self-expanding bolt 14 and the wall. In addition, the more vibrations the device is subjected to, the filling amount of the expansion material set inside the self-expanding bolt 14 will change accordingly.

[0041] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
