Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge safety protection, in particular to a bridge anti-collision guardrail. Background Art
[0002] With the rapid progress of urbanization, bridges, as important transportation hubs, carry the growing demand for vehicle and pedestrian traffic. However, this also brings many safety issues, especially the risk of traffic accidents on bridges. In many bridge designs, non-motorized vehicle lanes and motor vehicle lanes are often adjacent, or even shared in some cases, which greatly increases the risk of collisions between vehicles and pedestrians. In addition, even if physical isolation facilities such as guardrails are set up, these facilities usually only provide limited protection and may not effectively reduce the severity of the accident or prevent the occurrence of secondary accidents when a collision occurs.
[0003] Existing bridge anti-collision guardrail designs focus more on physical barriers, while ignoring the immediate response and subsequent handling when an accident occurs. For example, some guardrail designs include structural reinforcements to withstand greater impact forces, but this passive protection measure can often only reduce damage to the bridge structure when an accident occurs, but cannot effectively avoid harm to personnel or promptly warn subsequent vehicles to avoid secondary accidents.
[0004] In addition, although some modern bridge designs attempt to integrate sensors and warning systems to improve safety, the implementation of these systems is often limited by technical complexity, cost, and maintenance issues. For example, some bridges are equipped with pressure- or weight-sensing-based monitoring systems to detect the weight of vehicles crossing the bridge or warn of overload, but these systems generally cannot provide real-time accident detection or rapid response capabilities.
[0005] In summary, the bridge anti-collision guardrail in the prior art has the following shortcomings:
[0006] Passive protection: Most guardrails are designed for passive protection, which can only minimize damage to the bridge structure when an accident occurs, but cannot effectively prevent accidents or reduce injuries to personnel.
[0007] Lack of immediate response: Even if some bridges use sensor technology, they often lack effective immediate response mechanisms, such as automatic warnings or emergency notification systems, and are unable to take prompt measures to reduce the risk of secondary accidents when an accident occurs.
[0008] Maintenance and energy supply issues: Bridge guardrails with integrated electronic monitoring systems require a continuous power supply, and traditional power supply methods (such as connecting to the mains) increase installation complexity and long-term maintenance costs.
[0009] Poor environmental adaptability: Existing bridge guardrail designs often fail to fully consider performance maintenance under different environmental conditions, such as waterproofing, dustproofing, and weather resistance, which affects the accuracy and reliability of sensors and monitoring systems.

[0024] Modular design: The buffer block adopts modular design, which is easy to disassemble and replace, making maintenance and repair work more convenient and economical.
[0025] Intelligent monitoring and warning: The integrated pressure sensor and infrared sensor can monitor the traffic conditions on both sides of the bridge in real time, and trigger the warning module when the vehicle is too close or collides, reminding the vehicle to pay attention to safety or return to the normal driving road. In addition, the system can automatically send accident information to the traffic management center through the wireless communication module to request emergency assistance.

[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0036] See also Figure 1-5 , the utility model provides a technical solution:
[0037] like Figure 1 As shown, a bridge anti-collision guardrail includes a bridge deck 1, a panel 2, a pedestrian board 3, a railing 4 and a buffer block 5. The upper middle side of the bridge deck 1 is a carriageway, the panel 2 is fixedly arranged on the upper side of the side of the bridge deck 1, the upper side of the pedestrian board 3 is a non-motor vehicle lane, the pedestrian board 3 is fixedly arranged on the upper side of the panel 2 and a buffer groove 6 is formed between the pedestrian board 3 and the bridge deck 1, the railing 4 is fixedly arranged on the upper parts of both sides of the pedestrian board 3, a plurality of buffer blocks 5 are arranged evenly inside the buffer groove 6, and the upper side of the buffer block 5 is close to the lower side of the pedestrian board 3.
[0038] Reinforcement plates 7 are evenly arranged on the inner side of the connection between the bridge deck 1 and the enclosure 2, and a slot 8 matching the reinforcement plate 7 is arranged on the buffer block 5. A protrusion 9 is arranged on the upper side of the bridge deck 1 and on the inner side of the buffer block 5 and the pedestrian board 3. The bottom of the protrusion 9, the buffer block 5 and the enclosure 2 are respectively provided with corresponding lower water tanks 10. The height of the buffer block 5 is 1.2 meters. The buffer block 5 is made of rubber.
[0039] It also includes a pressure sensor 11, an infrared sensor 12, a control module 13, a power module 14, a warning module 15 and a wireless communication module 16. The control module 13 is electrically connected to the pressure sensor 11, the infrared sensor 12, the power module 14, the warning module 15 and the wireless communication module 16 respectively, and the power module 14 is electrically connected to the pressure sensor 11, the infrared sensor 12, the warning module 15 and the wireless communication module 16 respectively. The pressure sensor 11 is fixedly arranged on the buffer block 5, and the infrared sensor 12 is evenly fixedly arranged on the inner side of the pedestrian board 3. The pressure sensor 11 is embedded in the inner side of the buffer block 5, and a rainproof cover 17 is arranged on the upper part of the infrared sensor 12.
[0040] The utility model separates the non-motorized vehicle lane and the driving lane on a road surface with a relatively high height difference, thereby reducing the risk of pedestrians being killed or injured due to vehicle collisions on the bridge. The rubber buffer block 5 plays a buffering role when the vehicle collides, preventing the vehicle from directly colliding with the skeleton part of the guardrail (the enclosure 2, the pedestrian board 3, and the railing 4 in the utility model) and being damaged; secondly, the buffer block 5 can also play a role in reducing the vibration of the non-motorized vehicle road surface on the side of the pedestrian board 3. When a heavier vehicle drives onto the bridge deck, pedestrians can generally feel the vibration of the bridge deck intuitively, and the buffer block 5 can absorb the vibration generated by the bridge deck to a certain extent, thereby reducing the vibration of the road surface of the non-motorized vehicle lane; the buffer block 5 can also play a role in sound insulation. Since the buffer blocks 5 are evenly located on both sides of the bridge and can be set to a height higher than that of the car, the height is relatively high, which can effectively reduce the noise pollution caused to both sides of the bridge by the car driving on the bridge deck. The buffer block 5 is modularly designed and can be freely disassembled and replaced, which is convenient to use.
[0041] The utility model also involves a sensor component. When a vehicle is traveling too close to the two sides of the bridge deck, an infrared sensor 12 will be triggered, and the infrared sensor will transmit a signal to the control module 13. The control module 13 controls the alarm module 15 to start. The alarm module 15 can use a loud speaker to play a reminder to the car that is traveling too close to the road surface to return to the normal driving road surface, or a high-frequency flashing LED light can be used to remind. When the vehicle hits the buffer block 5 on both sides of the bridge, the pressure sensor 11 will be triggered. The pressure sensor 11 will transmit the received signal to the control module 15. The control module 15 will directly send the information of the accident to the nearby traffic management center through the wireless communication module 16 to request emergency support. The power module 14 can use a combination of solar panels and batteries to continuously power other modules.
