Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of tunnel traffic safety, and particularly to a safety warning device for tunnels with anti-collision function. Background Art
[0002] Tunnel warning devices are important safety infrastructure devices, mostly fixed on the side walls of tunnels, using reflective strips or plates, warning lights or signs to guide and warn passing vehicles. Sometimes, when a vehicle is too close to the warning signs on the tunnel side wall, it will hit and damage the warning signs on the tunnel side wall. For this problem, there is no good solution. Once a collision occurs, not only the warning signs are damaged, but also the vehicle and the people in the vehicle will suffer heavy losses. Therefore, it is of great significance to effectively warn the distance between the vehicle and the tunnel side wall.
[0003] To solve the above problems, the patent document CN214145577U discloses a safety warning device for tunnels with anti-collision function, including a tunnel safety warning component, which is rotatably arranged on an anti-collision fixed base component through a rotating hinge. First, the anti-collision fixed base component is installed on the side wall of the tunnel through fastening bolts and installation fixing holes, and the tunnel safety warning component installed on the tunnel side wall anti-collision fixed base component is used to conduct safety warning and route guidance for passing vehicles. When the tunnel safety warning component is not affected by external impact, the tunnel safety warning component is vertically fixed on the tunnel side wall relative to the anti-collision fixed base component for safety warning and route guidance. When the vehicle is too close to the tunnel safety warning component on the tunnel side wall, through the cooperation of the rotating hinge and the first anti-collision buffer spring and the second anti-collision buffer spring, the tunnel safety warning component makes a flip-type anti-collision rotation on the anti-collision fixed base component.
[0004] However, in actual application, even with elastic buffering, facing a vehicle moving at high speed, such a collision is still unacceptable, and it is difficult to provide sufficient warning to the vehicle before the collision, and it is also impossible to effectively collect information about vehicles crossing the boundary, which is not convenient for law enforcement, and the consequences after the subsequent collision are still relatively serious. Based on this, it is necessary to improve the existing technology. Summary of the Utility Model

[0026] Embodiment 1
[0027] A collision-proof tunnel safety warning device, such as Figures 1-4 As shown, it includes a plurality of columns 3 fixedly mounted on the inner surface of the tunnel side wall 1 and arranged longitudinally, a first mounting plate 4 arranged on the side of the column 3 away from the tunnel side wall 1, a second mounting plate 12 arranged on the side of the first mounting plate 4 facing the inside of the tunnel, a controller, and an alarm. The first mounting plate 4 is provided with a laser ranging sensor 6, and the laser ranging sensor 6 emits a laser line 7 in the opposite direction of the vehicle traveling. A solid line mark 8 is provided on the road surface where the laser line 7 faces the inside of the tunnel, and a driving restricted area is formed between the solid line mark 8 and the tunnel side wall 1. A vehicle information collection device and an alarm are installed on the second mounting plate 12. The laser ranging sensor 6, the alarm, and the vehicle information collection device are electrically connected to the controller through wires, and the controller is electrically connected to a power supply in the tunnel through wires.
[0028] In this embodiment, the driver can control the vehicle to avoid entering the restricted area when seeing the solid line mark on the ground. The solid line mark achieves the first warning effect and prevents the vehicle from colliding with the side wall of the tunnel. The vehicle information collection device is used to take photos of the vehicle and collect visual information such as the license plate number, driver, and crossing status for use by law enforcement agencies. The laser ranging sensor is used to detect vehicles entering the restricted area. When the detected distance value decreases rapidly, it means that the vehicle enters the restricted area. The vehicle information collection device is activated and an alarm is sounded to prompt the vehicle to cross the boundary and leave quickly, thus achieving the second warning.
[0029] Example 2
[0030] like Figures 1-4 As shown, the solid line mark 8 is set along the direction of the tunnel and protrudes from the road surface. The columns 3 are evenly distributed along the side wall of the tunnel. The columns 3 are cubic columns. A lamp post 31 is provided on one side of the column 3 facing the direction of vehicle travel. The lamp post 31 conspicuously indicates the position of the tunnel side wall. The plurality of lamp posts also constitute a guide symbol to guide the vehicle to travel along the correct track.
[0031] Example 3
[0032] like Figure 1 As shown, an anti-collision buffer layer 2 made of aerated bricks is provided on the inner surface of the tunnel side wall 1 and between adjacent columns 3. When a collision actually occurs, the anti-collision buffer layer 2 can reduce the loss of vehicles and personnel.
[0033] Example 4
[0034] like Figure 1As shown in the figure, a detection block 5 that cooperates with the laser ranging sensor 6 is provided on the first mounting plate 4 adjacent to the side facing the oncoming vehicle direction of the first mounting plate 4. Under normal circumstances, when no vehicle enters the restricted driving area, the laser line is projected onto the detection block, and the distance detected by the laser ranging sensor remains consistent. However, after a vehicle breaks in, the laser line is projected onto the vehicle, and the detected value changes rapidly.
[0035] Embodiment 5
[0036] As Figures 1-4 shown in the figure, the vehicle information acquisition device is a high-definition camera 13 provided on the side of the second mounting plate 12 facing the oncoming vehicle direction. When a vehicle breaks into the restricted driving area, the vehicle information is collected through the high-definition camera to provide a basis for subsequent law enforcement. Since traffic law enforcement has strong binding force, it can significantly improve the safety awareness of drivers.
[0037] Embodiment 6
[0038] As Figure 2 shown in the figure, the alarm is a display screen 14 provided on the second mounting plate 12, and the display screen 14 is configured with a warning text display module and an alarm module.
[0039] In this embodiment, the warning text display module refers to a text display module that provides warning information, such as the repeatedly presented text: Do not enter the restricted driving area to avoid collision risk; while the alarm module is the alarm text that indicates a certain vehicle has entered the restricted driving area: for example, each display screen simultaneously presents that a vehicle with a certain license plate number has entered the restricted driving area to prompt the driver to quickly correct the driving trajectory and at the same time prompt other drivers to avoid similar problems.
[0040] Embodiment 7
[0041] As Figures 1-4 shown in the figure, the top end of the first mounting plate 4 is connected to the second mounting plate 12 through a bracket 11, and the height of the bottom end of the second mounting plate 12 is higher than the maximum height of the vehicle 9 allowed to pass through the tunnel to avoid rubbing against the vehicle.
[0042] Embodiment 8
[0043] As Figure 3 shown in the figure, the first mounting plate 4 is also connected with an emergency avoidance mechanism
[0044] As Figure 3As shown in the figure, the emergency avoidance mechanism includes a speed sensor 15, an electric cylinder 16, and a linear slide rail (not shown in the figure) provided on the surface of the first mounting plate 4 facing the oncoming vehicle. The linear slide rail is longitudinally provided on the side of the column 3 facing the inside of the tunnel. The first mounting plate 4 is slidably connected to the linear slide rail through a slider on the side facing the tunnel side wall. An electric cylinder 16 is longitudinally provided on the outer surface of the column 3 above the linear slide rail. The fixed end of the electric cylinder 16 is fixedly connected to the column 3, and the telescopic end is fixedly connected to the top of the first mounting plate 4. The electric cylinder 16 and the speed sensor 15 are respectively electrically connected to the controller through wires.
[0045] In this embodiment, after the laser ranging sensor detects a signal that a vehicle has entered the restricted driving area, the controller, based on the distance information, speed information of the vehicle, and the self-response speed of the electric cylinder, raises the first mounting plate in advance through the electric cylinder to avoid the oncoming vehicle. At the same time, the electric cylinder can also accurately control the first mounting plate to return to the initial position.
[0046] Embodiment 9
[0047] The controller is signal-connected to the tunnel safety management center through a wireless signal transceiver module to realize the real-time monitoring of traffic violation signals and traffic accidents, which is beneficial to improving the management level of tunnel safety.
