Description
Technical Field
[0001] This utility model belongs to the technical field of crash barriers, specifically relating to a crash barrier that can provide real-time feedback on the location of the collision zone. Background Technology
[0002] Crash barriers are devices installed along the edge of highways to effectively buffer vehicle collisions. Existing crash barriers simply consist of corrugated guardrails installed between foundation piles, which cushion vehicle impacts. When these guardrails are struck, it usually indicates a traffic accident has occurred. However, existing crash barriers do not provide feedback on the location of the collision. In practice, the collision location is typically determined by visual warnings or the guardrail being within the surveillance camera's range. This results in a delay in locating the collision site, negatively impacting timely rescue efforts.
[0003] Therefore, in view of the shortcomings of existing crash barriers that cannot locate the collision position range, this utility model discloses a crash barrier that can provide real-time feedback on the collision range position. Utility Model Content
[0004] This utility model discloses a crash barrier that can provide real-time feedback on the location of the collision zone, enabling rapid location of the collision zone and facilitating subsequent rescue efforts.
[0005] This utility model is achieved through the following technical solution: A crash barrier capable of real-time feedback of the collision zone position includes spaced-apart support bases and a barrier body disposed between adjacent support bases. The upper and lower protective surfaces of the barrier body are respectively provided with corrugated guard plates, and an intermediate cylinder is disposed between the upper and lower corrugated guard plates, with the intermediate cylinder in contact with the corrugated guard plates. A vibration transmission element is disposed inside the intermediate cylinder, and a distributed vibration sensor is disposed inside the support base. The vibration transmission element is connected to the distributed vibration sensor.
[0006] When a vehicle impacts the corrugated guardrail, the guardrail deforms to cushion the impact and transmits the vibration to the intermediate cylinder. The intermediate cylinder protects the internal vibration transmission components while simultaneously transmitting the vibration. These components then rapidly transmit the vibration to distributed vibration sensors located within the support base. These sensors accurately detect the vibration transmitted from the guardrail itself and send the detected vibration signals to an external monitoring terminal via wired or wireless means. The external monitoring terminal can quickly and accurately determine that a collision has occurred. Furthermore, by locating the distributed vibration sensors that detected the vibration, the location of the impact zone can be determined, helping personnel to quickly pinpoint the impact location for subsequent handling.
[0007] To better realize this utility model, the vibration transmission component further includes a metal sleeve, a vibration transmission layer, and a vibration transmission optical fiber. The metal sleeve is disposed inside the intermediate cylinder and is in close contact with the inner wall of the intermediate cylinder. The vibration transmission optical fiber is disposed inside the metal sleeve, and a vibration transmission layer is filled between the vibration transmission optical fiber and the metal sleeve.
[0008] To better realize this utility model, the vibration transmission layer further includes an elastic resin layer and an elastic rubber layer.
[0009] To better realize this utility model, the metal sleeve is further provided with at least two sets of vibration transmission optical fibers.
[0010] To better realize this utility model, further, the upper and lower sides of the intermediate cylinder are provided with sliding grooves, and the end of the corrugated guard plate near the intermediate cylinder is provided with a sliding piece, which is inserted into the interior of the sliding groove and slidably connected with the sliding groove.
[0011] To better realize this utility model, the end of the slide groove near the middle cylinder is provided with a conformal arc surface, which is provided corresponding to the outer contour of the waveform guard plate.
[0012] To better realize this utility model, the support base is further provided with an installation cavity, a distributed vibration sensor is provided inside the installation cavity, and an insertion hole is provided on the side wall of the installation cavity. The vibration transmission optical fiber passes through the insertion hole and is connected to the distributed vibration sensor.
[0013] To better realize this utility model, the installation cavity is further provided with a GPS locator and a wireless signal transmitter, and the wireless signal transmitter is connected to the GPS locator and a distributed vibration sensor respectively.
[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention features corrugated guard plates on the upper and lower sides of the protective surface of the flower basket body, with an intermediate cylinder between the two corrugated guard plates. The corrugated guard plates buffer the impact and transmit the vibration generated by the impact to a vibration transmission component inside the intermediate cylinder. The vibration transmission component then rapidly transmits the vibration to a distributed vibration sensor located inside the support base. The distributed vibration sensor quickly and accurately detects the vibration and sends the vibration signal and the location range of the impacted support base to an external monitoring terminal. This enables rapid and accurate positioning of the impact location range, which is helpful for subsequent rescue operations. Attached Figure Description

Detailed Implementation
[0017] Example 1: This embodiment provides a type of crash barrier capable of real-time feedback on the location of the collision zone, such as... Figure 1 and Figure 2 As shown, the device includes a support base 1 spaced apart and a guardrail body 2 disposed between adjacent support bases 1. The upper and lower sides of the protective surface of the guardrail body 2 are respectively provided with corrugated guard plates 3, and an intermediate cylinder 4 is disposed between the upper and lower corrugated guard plates 3. The intermediate cylinder 4 is in contact with the corrugated guard plates 3. A vibration transmission element 5 is disposed inside the intermediate cylinder 4, and a distributed vibration sensor 6 is disposed inside the support base 1. The vibration transmission element 5 is connected to the distributed vibration sensor 6.
[0018] Highway guardrail posts are typically spaced approximately 4 meters apart. In actual use, the support bases 1 are installed at 4-meter intervals, with distributed vibration sensors 6 installed within each support base 1 at least 400 meters apart, forming a detection range with an interval of at least 400 meters. The support bases 1 are connected by the guardrail body 2, with the side of the guardrail body 2 closest to the road surface serving as the protective surface. Corrugated guard plates 3 are installed on the upper and lower sides of the protective surface using connecting bolts. The corrugated guard plates 3 have oblong holes, through which the connecting bolts pass and align with the connecting holes on the guardrail body 2. This ensures that the corrugated guard plates 3 have sufficient deformation capacity under impact while being installed on the guardrail body 2, effectively absorbing and buffering the impact and smoothly transmitting the vibration to the intermediate cylinder 4.
[0019] The intermediate cylinder 4 is constructed from sequentially connected metal sections. It protects the vibration transmission component 5, and its upper and lower sides contact the upper and lower corrugated guard plates 3 respectively, ensuring smooth vibration transmission to the vibration transmission component 5. When the corrugated guard plate 3 is impacted, the vibration is transmitted through the intermediate cylinder 4 to the vibration transmission component 5, and then further transmitted to the distributed vibration sensors 6 located inside the support base 1. The distributed vibration sensors 6 accurately detect the vibration and transmit the vibration signal to an external detection terminal via wired or wireless means. The external detection terminal can quickly determine if a collision has occurred with the guardrail based on the received vibration signal. Furthermore, by locating the distributed vibration sensors 6 that detected the vibration signal, it can pinpoint the collision location, helping personnel quickly locate the collision site and organize subsequent rescue efforts.
[0020] Example 2: This embodiment is a further optimization based on Embodiment 1, such as... Figure 1 and Figure 4 As shown, the vibration transmission component 5 includes a metal sleeve 51, a vibration transmission layer 52, and a vibration transmission optical fiber 53. The metal sleeve 51 is disposed inside the intermediate cylinder 4 and is in close contact with the inner wall of the intermediate cylinder 4. The vibration transmission optical fiber 53 is disposed inside the metal sleeve 51, and the vibration transmission layer 52 is filled between the vibration transmission optical fiber 53 and the metal sleeve 51.
[0021] The metal sleeve 51 is made of seamless or spiral metal tubing, and its thickness is greater than or equal to 2mm. This ensures that the metal sleeve 51 can effectively protect the vibration-conducting optical fiber 53 while also transmitting vibration to it, avoiding significant attenuation of the vibration. The vibration-conducting optical fiber 53 has a core count of greater than or equal to 100. A vibration-conducting layer 52 is filled between the outer surface of the vibration-conducting optical fiber 53 and the metal sleeve 51. Through the vibration-conducting layer 52, vibration can be quickly and effectively transmitted to the vibration-conducting optical fiber 53. The vibration-conducting optical fiber 53 also has self-healing properties; that is, even if some cores break, it can recover on its own or continue to transmit vibration through the remaining intact cores. This ensures the reliability of the vibration-conducting optical fiber 53 and eliminates the need for frequent manual maintenance.
[0022] Furthermore, the vibration transmission layer 52 includes an elastic resin layer and an elastic rubber layer, which are arranged sequentially from the outside to the inside, and the thickness of the elastic resin layer is less than or equal to 3 mm. By setting the elastic resin layer and the elastic rubber layer, the metal sleeve 51 is internally coupled into a whole, while also ensuring the smooth transmission of vibration and avoiding the problem of insensitivity to vibration transmission.
[0023] Furthermore, the metal sleeve 51 is provided with at least two sets of vibration transmission optical fibers 53. The two sets of vibration transmission optical fibers 53 serve as backups for each other. Even if one set of vibration transmission optical fibers 53 fails, vibration can still be transmitted through the other set of vibration transmission optical fibers 53.
[0024] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.
[0025] Example 3: This embodiment is a further optimization based on the above embodiment 1 or 2, such as... Figure 3 As shown, the upper and lower sides of the intermediate cylinder 4 are provided with sliding grooves 100, and the end of the corrugated guard plate 3 near the intermediate cylinder 4 is provided with a sliding piece 200. The sliding piece 200 is inserted into the interior of the sliding groove 100 and is slidably connected to the sliding groove 100. The end of the sliding groove 100 near the intermediate cylinder 4 is provided with a conformal arc surface 300, which corresponds to the outer contour of the corrugated guard plate 3.
[0026] When the corrugated guard plate 3 is deformed by an impact, the slider 200 moves along the slide groove 100 to ensure that the corrugated guard plate 3 can smoothly contact the intermediate cylinder 4, so as to smoothly transmit the vibration to the intermediate cylinder 4. By providing a conformal arc surface 300 at one end of the slide groove 100 near the intermediate cylinder 4, when the slider 200 slides along the slide groove 100, the conformal arc surface 300 contacts the outer surface of the corrugated guard plate 3, assisting the corrugated guard plate 3 in buffering the impact.
[0027] The other parts of this embodiment are the same as those in Embodiment 1 or 2 above, so they will not be described again.
[0028] Example 4: This embodiment is a further optimization based on any one of embodiments 1-3 above. The support base 1 is provided with a mounting cavity, such as... Figure 1 As shown, a distributed vibration sensor 6 is installed inside the mounting cavity. An insertion hole is provided on the side wall of the mounting cavity, through which the vibration transmission optical fiber 53 passes and connects to the distributed vibration sensor 6. A GPS locator and a wireless signal transmitter are also installed inside the mounting cavity, with the wireless signal transmitter connected to both the GPS locator and the distributed vibration sensor 6.
[0029] A power supply is provided at the support base 1 to power the distributed vibration sensor 6, GPS locator, and wireless signal transmitter. The power supply can be a solar power module or directly connected to a nearby power line. The distributed vibration sensor 6, GPS locator, and wireless signal transmitter are all commercially available products, and their specific structures will not be described in detail here. After detecting vibration, the distributed vibration sensor 6 amplifies the signal via the wireless signal transmitter and sends it to an external monitoring terminal, which helps to quickly and accurately determine the location of the collision zone. Simultaneously, the GPS locator sends the position of the support base 1 within the collision zone to the external monitoring terminal, thereby enabling rapid location of the collision zone.
[0030] The other parts of this embodiment are the same as any one of the embodiments 1-3 above, so they will not be described again.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
