Description

Technical Field

[0001] This utility model relates to the field of traffic safety protection technology, and in particular to a vehicle interception device outside a tunnel. Background Technology

[0002] During the use of highway tunnels, if an emergency occurs inside the tunnel, such as a traffic accident or fire, traffic congestion will occur rapidly. If following vehicles cannot notice the congestion ahead in time, it can easily lead to an accident.

[0003] Currently, warning methods outside tunnels mainly include the use of accident signs, traffic cones, water-filled barriers, crash barriers, and tunnel lane indicators. However, these methods have the following problems: first, the warning effect is not obvious, and some drivers may ignore the warning signs; second, they cannot effectively intercept out-of-control vehicles. In addition, some warning devices using water curtain projection are highly dependent on weather conditions and may affect drivers' visibility, causing secondary accidents.

[0004] Regarding interception technology, existing technologies include devices that use road surface lifting mechanisms to intercept vehicles. However, such devices require damaging the existing road structure, making construction difficult, and their durability is poor due to long-term exposure to vehicle loads. Other devices utilize tunnel structures to install interception equipment, but this requires modifications to the tunnel structure, potentially affecting tunnel safety, and cannot meet the stress requirements for vehicle interception under extreme conditions.

[0005] Therefore, there is a lack of existing technologies for a vehicle interception device outside the tunnel that can effectively warn and intercept out-of-control vehicles without affecting the safety of the road and tunnel structure. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0039] Reference Figures 1 to 8 The tunnel-exterior vehicle interception device shown includes:

[0040] Foundation 1, set on both sides of the road, is used to support the entire device;

[0041] Support frame 2, fixed on foundation 1, includes support columns and crossbeams. The crossbeams are hollow structures used to conceal the buffer interception net 3.

[0042] The buffer interception net 3 is installed inside the crossbeam supporting the gantry 2 and is used to intercept out-of-control vehicles;

[0043] Support platform 9, located at the bottom of the crossbeam, is used to support the folded buffer interception net 3;

[0044] The lifting mechanism includes a screw 6, a nut 7 and a lifting power device 5. The top end of the screw 6 is connected to the lifting power device 5 and the bottom end is fixed on the foundation 1. The nut 7 meshes with the screw 6 and is connected to the support platform 9, and is used to drive the support platform 9 to lift and lower, so as to realize the deployment and retrieval of the buffer interception net 3.

[0045] The remote controller 8 is used to remotely control the operation of the lifting power unit 5.

[0046] I. Foundation 1: Foundation 1 is located on both sides of the road and serves as the supporting structure for the entire device. Foundation 1 is constructed of cast concrete, possessing high strength and stability. Its upper part is bolted to the supporting columns of the supporting gantry 2, ensuring that the supporting gantry 2 is firmly fixed to Foundation 1.

[0047] The main function of foundation 1 is to provide stable support for the entire vehicle interception device outside the tunnel, ensuring that the device remains stable under external forces such as vehicle impacts and will not tip over or shift. At the same time, foundation 1 also provides a fixed mounting point for the screw 6 in the lifting mechanism.

[0048] Implementation method: Excavate foundation pits at suitable locations on both sides of the road according to design requirements, and then pour concrete foundation 1. After the concrete reaches the design strength, connect and fix the supporting columns of the supporting gantry 2 to the foundation 1 with bolts.

[0049] The supporting gantry 2 is fixed to the foundation 1 and consists of supporting columns and crossbeams. The lower ends of the supporting columns are bolted to the foundation 1, and the two ends of the crossbeams are connected to the upper ends of the two supporting columns respectively. The crossbeams have a hollow structure, and the internal space is used to hide the buffer interception net 3. A rigid support platform 9 is provided at the bottom of the crossbeams to support the folded buffer interception net 3.

[0050] The main function of the supporting gantry 2 is to provide support and concealment space for the buffer interception net 3. Its hollow beam structure not only conceals the buffer interception net 3, ensuring it does not obstruct normal road traffic when not in use, but also allows the buffer interception net 3 to be quickly deployed when needed to intercept vehicles. Simultaneously, the supporting gantry 2 also provides an installation location for the screw 6 in the lifting mechanism.

[0051] Implementation: The supporting columns and beams of the supporting gantry 2 are typically made of steel and fabricated according to the design drawings. The supporting columns are installed on the foundation 1 and secured with bolts. Then, the beams are connected to the upper ends of the supporting columns to ensure the stability and robustness of the entire supporting gantry 2 structure.

[0052] The buffer net 3 is installed inside the crossbeam supporting the gantry 2. Its top is connected to the inside of the crossbeam by the buffer net connecting cable 4, and its bottom is connected to the support platform 9. In normal operation, the buffer net 3 is folded and hidden inside the crossbeam, and is unfolded and retracted by raising and lowering the support platform 9.

[0053] Function: The buffer interception net 3 is the core component of this device, used to intercept out-of-control vehicles. Made of flexible materials such as polyethylene fiber, it possesses excellent elasticity and buffering capabilities, absorbing the instantaneous impact energy of vehicles and reducing the risk of vehicle damage and personal injury. Furthermore, the design of the buffer interception net 3 allows it to be folded and hidden when not in use, without affecting normal road traffic.

[0054] Implementation: The buffer net 3 is woven from high-strength polyethylene fiber flexible material, possessing excellent toughness and elasticity. During installation, the top of the buffer net 3 is connected to the inside of the crossbeam via the buffer net connecting cable 4, and the bottom is connected to the support platform 9. The deployment and retraction of the buffer net 3 are achieved through the control of the lifting mechanism.

[0055] The support platform 9 is located at the bottom of the crossbeam supporting the gantry 2 and is used to support the folded buffer netting 3. Nuts 11 are provided at both ends of the support platform 9, which engage with the screw 6. By rotating the screw 6, the nuts 11 drive the support platform 9 to move up and down along the screw 6, thereby realizing the unfolding and retraction of the buffer netting 3.

[0056] The main function of the support platform 9 is to support the folded buffer net 3, ensuring that the buffer net 3 can be stably hidden inside the crossbeam when not in use. At the same time, the support platform 9, in cooperation with the screw 6 and nut 11, enables the buffer net 3 to be unfolded and retracted.

[0057] Implementation: The support platform 9 is typically made of rigid material, possessing sufficient strength and stability. During installation, the support platform 9 is placed at the bottom of the crossbeam, and the bottom of the buffer interception net 3 is connected to the support platform 9. Nuts 11 are then installed at both ends of the support platform 9 and engage with the screws 6.

[0058] The lifting mechanism includes a screw 6, a nut 7, and a lifting power device 5. The top end of the screw 6 is connected to the lifting power device 5, and the bottom end is fixed to the foundation 1 via a bearing. The nut 7 engages with the screw 6 and is connected to the support platform 9. Driven by the lifting power device 5, the screw 6 rotates, causing the nut 7 to move up and down along the screw 6, thereby realizing the lifting and lowering of the support platform 9, and thus enabling the deployment and retraction of the buffer interception net 3.

[0059] Function: The main function of the lifting mechanism is to drive the support platform 9 to rise and fall, thereby enabling the deployment and retraction of the buffer interception net 3. Through the control of the lifting power unit 5, the rotation of the screw 6 can precisely control the position of the support platform 9, ensuring that the buffer interception net 3 can be quickly deployed when needed to intercept out-of-control vehicles, and quickly retracted after the mission is completed, restoring normal road traffic.

[0060] Implementation: The lifting power unit 5 typically uses a motor, which is connected to the screw 6 via a transmission mechanism. During installation, the top end of the screw 6 is connected to the lifting power unit 5, and the bottom end is fixed to the foundation 1 via a bearing. Then, the nut 7 is installed on the screw 6 and connected to the support platform 9. The operation of the lifting power unit 5 is controlled by a remote controller 8 to realize the forward and reverse rotation of the screw 6, thereby driving the lifting and lowering of the support platform 9.

[0061] The remote controller 8 is connected to the lifting power unit 5 via a communication line for remote control of the operation of the lifting power unit 5. The remote controller 8 can be installed in the control center for manual control by operators, or it can be linked with other equipment to achieve automated control.

[0062] Function: The main function of the remote controller 8 is to remotely control the lifting power device 5, allowing operators to control the deployment and retraction of the buffer interception net 3 from a distance. Through the remote controller 8, operators can react promptly to the situation inside the tunnel, ensuring rapid response of the device and improving the efficiency of traffic safety management.

[0063] Implementation: The remote controller 8 can be connected to the lifting power unit 5 via wireless or wired communication. During installation, the remote controller 8 is installed in the control center and connected to the lifting power unit 5 via a communication line. Operators can send control commands through the interface or buttons of the remote controller 8 to remotely operate the lifting power unit 5.

[0064] Operating Procedure: When an emergency occurs inside the tunnel, requiring the interception of an out-of-control vehicle outside the tunnel, the operator sends a command via the remote controller 8 to activate the lifting power unit 5. The lifting power unit 5 drives the screw 6 to rotate clockwise, and the nut 7 moves downward along the screw 6, causing the support platform 9 to descend. As the support platform 9 descends, the buffer interception net 3 gradually unfolds until it is fully unfolded and in the interception state.

[0065] When the buffer barrier net 3 needs to be retrieved, the operator sends a command via the remote controller 8 to reverse the lifting power unit 5. The screw 6 reverses, and the nut 7 moves upward along the screw 6, causing the support platform 9 to rise. As the support platform 9 rises, the buffer barrier net 3 gradually folds until it is completely folded and hidden inside the crossbeam of the supporting gantry 2, restoring normal road traffic.

[0066] The above is a detailed description of the components of the vehicle interception device outside the tunnel, including their connection relationships, functions, and implementation methods. Through the coordinated operation of these components, this device can effectively intercept out-of-control vehicles, prevent secondary accidents, and not affect normal road traffic.

[0067] In some specific embodiments, the buffer interception net 3 is made of flexible polyethylene fiber material, which is elastic and can absorb the instantaneous impact energy of the vehicle.

[0068] The buffer interception net 3 is made of flexible polyethylene fiber material, which has good elasticity and toughness. Its top is connected to the crossbeam supporting the gantry 2 via the buffer interception net connecting cable 4, and its bottom is connected to the support platform 9.

[0069] Polyethylene fiber materials possess high strength and good elasticity, enabling them to absorb the instantaneous impact energy of a vehicle, reducing the extent of damage during a collision and lowering the risk of personal injury. The cushioning properties of this material make the interception process smoother, preventing excessive damage to the vehicle.

[0070] The buffer netting 3 is woven from high-strength polyethylene fibers to form a mesh structure. During installation, the top of the buffer netting 3 is fixed to the inside of the crossbeam of the supporting gantry 2 via connecting cables 4, and the bottom is connected to the support platform 9. The buffer netting 3 can be unfolded and folded by raising and lowering the support platform 9.

[0071] In some specific embodiments, the top of the buffer interception net 3 is connected to the crossbeam of the supporting gantry 2, and the bottom is connected to the support platform 9. The buffer interception net 3 can be unfolded and folded by raising and lowering the support platform 9.

[0072] The top of the buffer interception net 3 is connected to the crossbeam of the supporting gantry 2 via connecting cable 4, and the bottom is connected to the support platform 9. The support platform 9 is engaged with the screw 6 via nut 11, and the screw 6 is driven by the lifting power device 5. This design allows the buffer interception net 3 to be quickly deployed when needed to intercept out-of-control vehicles, and to be quickly folded and retracted after the mission is completed, restoring normal road traffic. At the same time, the folding and hiding design does not affect the normal use of the road in normal circumstances.

[0073] When a vehicle needs to be intercepted, the lifting power unit 5 is activated via the remote controller 8. The screw 6 rotates forward, and the nut 11 lowers the support platform 9, causing the buffer interception net 3 to gradually unfold. After the interception task is completed, the operation is reversed. The screw 6 rotates backward, the support platform 9 rises, and the buffer interception net 3 folds and is hidden inside the crossbeam.

[0074] In some specific embodiments, a slider 12 is provided inside the crossbeam supporting the gantry 2. The slider 12 is fitted onto the screw 6 and can slide along the screw 6. The slider 12 is laterally connected to the buffer interception net 3. The slider 12 is fitted onto the screw 6 and can slide up and down along the screw 6. The slider 12 is connected to the lateral portion of the buffer interception net 3 through a connector to ensure that the buffer interception net 3 remains stable during unfolding and folding. The design of the slider 12 makes the buffer interception net 3 more stable during unfolding and folding, avoiding twisting or deformation of the buffer interception net 3 due to external forces, thereby improving the reliability and service life of the device.

[0075] During installation, the slider 12 is fitted onto the screw 6 and connected to the transverse portion of the buffer net 3 via a connector such as a steel cable or connecting rod. When the screw 6 rotates, the slider 12 moves along the screw 6, causing the buffer net 3 to unfold or fold.

[0076] In some specific embodiments, the lifting power device 5 is a motor, which is connected to the screw 6 through a transmission mechanism to drive the screw 6 to rotate forward or in reverse.

[0077] The lifting power unit 5 is a motor, which is connected to the screw 6 via a transmission mechanism such as gear transmission or belt transmission. The output shaft of the motor drives the screw 6 to rotate forward or backward through the transmission mechanism.

[0078] The motor, as the power source, provides stable power output, ensuring smooth and controllable rotation of the screw 6. By controlling the forward and reverse rotation of the motor, the deployment and retraction of the buffer interception net 3 can be precisely controlled. A suitable motor is selected as the lifting power unit 5 and connected to the screw 6 via a transmission mechanism. During installation, ensure the motor's output shaft is correctly connected to the transmission mechanism, and control the motor's start, stop, and forward / reverse rotation via a remote controller 8.

[0079] In some specific embodiments, the remote controller 8 can be connected to the lifting power device 5 via wireless or wired communication to realize remote control of the lifting power device 5.

[0080] The remote controller 8 connects to the lifting power unit 5 via wireless communication such as Wi-Fi, 4G / 5G, or wired communication such as Ethernet, RS485. The remote controller 8 can be installed in the control center and operated manually by personnel or linked with other equipment.

[0081] The use of the remote controller 8 allows operators to control the deployment and retraction of the buffer interception net 3 from a distance, improving operational convenience and safety. Meanwhile, wireless communication makes the installation and deployment of the device more flexible, while wired communication ensures signal stability and reliability.

[0082] Choose the appropriate communication method based on actual needs. If wireless communication is used, a wireless communication module needs to be installed between the remote controller 8 and the lifting power unit 5, and network configuration must be performed. If wired communication is used, communication lines need to be laid, and the line connections must be ensured to be correct.

[0083] In some specific embodiments, the foundation 1 is made of concrete and is used to fix and support the gantry 2 and provide stable support.

[0084] Foundation 1, constructed of concrete, is located on both sides of the road to secure and support the gantry 2, providing stable support. The upper part of foundation 1 is connected to the support columns of the gantry 2 by bolts.

[0085] The concrete foundation 1 has high strength and stability, and can withstand the impact of vehicles and the weight of the device itself, ensuring that the device remains stable during operation and will not tilt or shift.

[0086] Excavate foundation pits at suitable locations on both sides of the road, and pour concrete foundation 1 according to design requirements. After the concrete reaches the design strength, fix the support columns of the supporting gantry 2 to the foundation 1 with bolts.

[0087] In some specific embodiments, screws 6 are disposed on both sides of the supporting gantry 2, parallel to the supporting columns, and nuts 7 are disposed at both ends of the support platform 9, engaging with screws 6.

[0088] Screws 6 are located on both sides of the supporting gantry 2, parallel to the supporting columns. The top end of screws 6 is connected to the lifting power device 5, and the bottom end is fixed to the foundation 1 by bearings. Nuts 7 are located at both ends of the support platform 9 and engage with screws 6.

[0089] This configuration allows the screw 6 to rotate smoothly, and the nut 7 to move up and down along the screw 6, thereby driving the support platform 9 to rise and fall, realizing the deployment and retraction of the buffer interception net 3. The parallel arrangement of the screw 6 ensures that the raising and lowering of the support platform 9 is smooth and synchronized.

[0090] Install screw rods 6 on both sides of the supporting gantry 2, ensuring that the screw rods 6 are parallel to the supporting columns. Install nuts 7 at both ends of the support platform 9 and engage with the screw rods 6. Drive the screw rods 6 to rotate through the lifting power device 5 to achieve the lifting and lowering of the support platform 9.

[0091] In some specific embodiments, the buffer interception net 3 is folded and hidden inside the crossbeam of the supporting gantry 2 in the normal state. When it is necessary to intercept an out-of-control vehicle, the buffer interception net 3 is deployed through the lifting mechanism.

[0092] In its normal operating state, the buffer interception net 3 is folded and hidden within the crossbeam supporting the gantry 2. When it is necessary to intercept an out-of-control vehicle, the buffer interception net 3 is deployed via a lifting mechanism.

[0093] This design does not affect normal road traffic under normal conditions, while it can quickly deploy the buffer interception net 3 when needed to intercept out-of-control vehicles and prevent secondary accidents.

[0094] In normal operation, the buffer interception net 3 is folded and hidden inside the crossbeam of the supporting gantry 2 via the lifting mechanism. When it is necessary to intercept a vehicle, the lifting power unit 5 is activated via the remote controller 8, the screw 6 rotates forward, driving the support platform 9 to descend, and the buffer interception net 3 gradually unfolds.

[0095] In some specific embodiments, after completing the interception task, the buffer interception net 3 is retracted into the crossbeam of the supporting gantry 2 by a lifting mechanism to restore normal road traffic.

[0096] After completing its interception mission, the buffer interception net 3 is retracted into the crossbeam supporting the gantry 2 via a lifting mechanism, restoring normal road traffic.

[0097] This design ensures that the buffer interception net 3 can be quickly retrieved after completing its task, avoiding any impact on road traffic and improving the efficiency and safety of the device.

[0098] After completing the interception task, the lifting power device 5 is activated by the remote controller 8, the screw 6 reverses, driving the support platform 9 to rise, and the buffer interception net 3 gradually folds and hides inside the crossbeam, restoring normal traffic flow on the road.

[0099] (I) Facility Structure

[0100] The tunnel interception device is installed above the roadway at the tunnel entrance, with the supporting columns located outside the roadside clearance.

[0101] The tunnel entrance interception device consists of a foundation 1, a supporting gantry 2, a buffer interception net 3, a buffer interception net connecting cable 4, a lifting power device 5, a lifting screw 6, a lifting nut 7, and a remote controller 8.

[0102] Foundation 1, located on both sides of the road, is made of concrete and serves to support the gantry.

[0103] The supporting gantry 2 is connected to the foundation 1 using bolts. The supporting gantry 2 consists of supporting columns and crossbeams, and is used to support the overall structure of the device. The crossbeam of the supporting gantry is a central control structure used to conceal the folded buffer interception net 3. A rigid support platform 9 is provided at the bottom of the crossbeam to support the folded buffer interception net.

[0104] The buffer interception net 3 is made of flexible materials such as polyethylene fiber, which has a certain degree of elasticity and can absorb the instantaneous impact energy of the vehicle, thus achieving buffer interception of the vehicle.

[0105] In its normal state, the buffer interception net 3 is folded up and lifted into the gantry beam by the support platform 9 for concealment.

[0106] The supporting gantry 2 has screw rods 10 parallel to the columns on both sides. The top of the screw rod 10 is connected to the lifting power device 5, and the bottom is fixed to the concrete foundation by bearings. The screw rod 10 can rotate forward and backward under the drive of the lifting power device 5.

[0107] The support platform 9 runs through the bottom of the support structure, and nuts 11 are installed at both ends.

[0108] The screw 10 and nut 11 mesh like a screw and nut. When the screw 10 rotates under the drive of the lifting power device 5, the nut 11 can move along the screw 10. By changing the rotation direction of the screw 10, the nut 11 can move in different directions. Furthermore, by rotating the screw 10 forward and backward, the support platform 9 can be raised or lowered, and the buffer interception net 3 can be deployed and folded.

[0109] The lifting power unit 5 can be remotely controlled to achieve forward and reverse rotation of the screw 10. The remote controller 8 is located in the control center and can be manually controlled by the operator or controlled in conjunction with other equipment.

[0110] The buffer interception net 3 is connected laterally to the slider 12, which is fitted onto the screw 10 and can slide along the screw 10.

[0111] The top of the buffer interception net 3 is connected to the crossbeam of the supporting gantry, and the bottom is connected to the support platform 9.

[0112] The buffer interception net 3 is deployed by tensioning the slider 12, the support platform 9, and the supporting gantry 2. After deployment, the buffer interception net 3 is used to intercept out-of-control vehicles.

[0113] (II) Operation Process

[0114] Facility control personnel receive information about a traffic accident occurring inside the tunnel through monitoring facilities or other information channels, indicating that a vehicle outside the tunnel is out of control and about to crash into the tunnel. Facility control personnel activate the interception system using the remote controller 8 or through linkage control with other equipment.

[0115] The remote controller 8 controls the lifting power device 5 to drive the screw 10 to rotate. The screw drives the lowest nut 11 to move downward. The nut 11 drives the support platform 9 to descend. The support platform 9 drives the buffer interception net 3 to descend. At the same time, the slider 12 descends along the screw 10, gradually completing the deployment of the buffer interception net 3.

[0116] After the buffer interception net 3 is deployed, it is used to warn and intercept out-of-control vehicles.

[0117] If the buffer net 3 is not hit by a vehicle, the screw 10 can be reversed to drive the bottom nut 11 to rise, which in turn drives the support platform 9 to rise, thereby realizing the recovery of the buffer net 3 and returning it to the crossbeam of the support structure 2.

[0118] This utility model's tunnel vehicle interception device uses remote control to deploy and retract a buffer interception net, thereby intercepting out-of-control vehicles and preventing them from entering the tunnel. Its working principle is as follows:

[0119] 1. Normal state

[0120] Under normal circumstances, the buffer barrier net 3 is folded and hidden inside the hollow crossbeam of the supporting gantry 2, without affecting normal road traffic. At this time, the support platform 9 is located at the highest position at the bottom of the crossbeam, and the buffer barrier net 3 is completely retracted.

[0121] 2. Interception Operation

[0122] When an emergency occurs inside the tunnel, such as a traffic accident or fire, requiring the interception of out-of-control vehicles outside the tunnel, the operator sends a command via the remote controller 8 to activate the lifting power unit 5. The lifting power unit 5 drives the screw 6 to rotate forward, and the nut 11 moves downward along the screw 6, causing the support platform 9 to descend. As the support platform 9 descends, the buffer interception net 3 gradually unfolds until it is fully unfolded and in the interception state.

[0123] 3. Buffering effect

[0124] The buffer net 3 is made of flexible materials such as polyethylene fiber, and has good elastic cushioning function. When an out-of-control vehicle collides with the buffer net 3, the buffer net 3 can absorb the instantaneous impact energy of the vehicle, reduce the impact force of the vehicle, and thus reduce the risk of vehicle damage and personal injury.

[0125] 4. Recycling Operation

[0126] After the interception mission is completed, the operator sends a command via remote controller 8 to reverse the lifting power unit 5. The screw 6 reverses, and the nut 11 moves upward along the screw 6, causing the support platform 9 to rise. As the support platform 9 rises, the buffer interception net 3 gradually folds and retracts into the crossbeam supporting the gantry 2, restoring normal road traffic.

[0127] 5. Remote control

[0128] The remote controller 8 is connected to the lifting power unit 5 via wireless or wired communication, allowing operators to control the device from a distance. This remote control method improves operational convenience and safety, and enables rapid response to emergencies within the tunnel.

[0143] Example 2: Slider-assisted design

[0144] Structural improvements

[0145] In this embodiment, a slider 12 is provided inside the crossbeam supporting the gantry 2. The slider 12 is fitted onto the screw 6 and can slide along the screw 6. The slider 12 is connected to the transverse portion of the buffer interception net 3 through a connector to ensure that the buffer interception net 3 remains stable during unfolding and folding.

[0146] Operation process

[0147] Normal state: The buffer interception net 3 is folded and hidden inside the crossbeam, and the slider 12 is located at the top of the screw 6.

[0148] Interception Operation: Start the lifting power device 5, the screw 6 rotates forward, the nut 11 drives the support platform 9 to descend, and at the same time the slider 12 slides along the screw 6, and the auxiliary buffer interception net 3 unfolds smoothly.

[0149] Buffering function: When an out-of-control vehicle collides with the buffer interception net 3, the buffer interception net 3 absorbs the impact energy.

[0150] Recovery operation: Control the lifting power device 5 to reverse, the screw 6 to reverse, the nut 11 drives the support platform 9 to rise, the slider 12 slides along the screw 6, and the auxiliary buffer interception net 3 is smoothly folded and recovered into the crossbeam.

[0151] Example 3: Linkage Control and Automation

[0152] Structural improvements

[0153] In this embodiment, the remote controller 8 can not only manually control the lifting power unit 5, but also link with other traffic monitoring equipment to achieve automated control. For example, when the sensors in the tunnel detect an anomaly, the system automatically triggers an interception operation.

[0154] Operation process

[0155] Normal state: The buffer interception net is folded and hidden inside the crossbeam, and the system is in standby state.

[0156] Linkage trigger: When the sensors in the tunnel detect abnormal situations such as vehicle speeding or fire, they automatically send a signal to the remote controller 8.

[0157] Interception Operation: The remote controller 8 automatically starts the lifting power unit 5, the screw 6 rotates forward, the nut 11 drives the support platform 9 to descend, and the buffer interception net 3 unfolds.

[0158] Buffering function: When an out-of-control vehicle collides with the buffer interception net 3, the buffer interception net 3 absorbs the impact energy.

[0159] Recovery Operation: After the abnormal situation is resolved, the remote controller 8 automatically controls the lifting power unit 5 to reverse, the screw 6 to reverse, the nut 11 to drive the support platform 9 to rise, and the buffer interception net 3 to fold and retract into the crossbeam.

[0160] By adopting the above-disclosed technical solution of this utility model, the following beneficial effects are obtained:

[0161] This invention features a more rational structural design. Compared to traditional interception facilities mounted on tunnel walls, this invention requires no modification to the tunnel structure and does not compromise tunnel safety. The supporting structure is located on both sides of the road, ensuring no damage to the road structure during installation and use. The buffer interception net itself has a buffering function, absorbing the energy of vehicle impacts and preventing serious damage. This invention can buffer and intercept out-of-control vehicles, significantly reducing the likelihood of vehicles entering the tunnel and effectively preventing traffic accidents and secondary accidents that may occur if an accident has already occurred inside the tunnel.

[0162] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
