Description

Technical Field

[0001] This utility model relates to the field of traffic control technology, and in particular to a flexible barrier. Background Technology

[0002] In recent years, highway traffic accidents have occurred frequently, especially in the event of sudden disasters, where the response speed and safety protection capabilities of traditional traffic control and barrier facilities have been clearly insufficient. For example, after the landslide disaster on the Chayang section of the Meida Expressway in May 2024 and the collapse of the Yanping Village No. 2 Bridge on the Zhashui section of the Danning Expressway in July 2024, the Ministry of Transport put forward clearer and stricter requirements for emergency blocking and dynamic traffic control on highways.

[0003] Currently, the traffic blocking and warning methods commonly used in highway scenarios mainly include the following categories: (1) Signal and lighting facilities: including road traffic lights, roadside variable lane control signs, simple text prompt screens and flashing warning lights, etc. These facilities are usually implemented by gantry type or roadside installation. Their main drawback is that visibility is significantly reduced under complex weather conditions such as rain, fog, night or backlight; the intensity of visual stimulation is insufficient, and drivers are prone to ignore or misjudge; there is a lack of spatial three-dimensional prompts, and it is impossible to form a clear blocking perception; (2) Voice and broadcast warnings: such as wired broadcasts, vehicle radios and other voice information means. The problem is that the sound signal is easily interfered with by environmental noise in open spaces; the propagation distance is limited, and the signal strength decreases rapidly with the increase of distance; the information is not timely and discontinuous, and it is difficult to form an effective immediate blocking effect. (3) Mechanical rigid blocking facilities: such as electric barriers, metal gates or telescopic barriers. Although these devices can achieve physical closure, they are prone to strong collisions and impacts in high-speed vehicle scenarios, resulting in vehicle damage or personal injury, and posing a high risk of secondary accidents; (4) Manually deployed facilities: including traffic cones, water barriers, barriers and other simple blocking devices. The main problem is that the deployment cycle is long and manual operation is required, which cannot meet the emergency requirements of rapid response and automatic deployment in the event of a sudden accident on the highway; (5) Blocking method based on water curtain imaging: visual warning barriers are formed by water curtain projection, although It has a certain warning effect, but it has obvious safety hazards: water mist condenses on the road surface, which can easily lead to slipperiness and a decrease in the coefficient of friction; it may freeze in low temperature environment, causing the vehicle to skid or lose control; at the same time, the equipment has a large water consumption and high maintenance cost, and is not suitable for long-term continuous operation; (6) Imaging blocking method based on smoke projection: virtual prompt images are formed by spraying smoke and combining it with laser or projection. Its defects are: poor visibility when the ambient light is strong during the day, making it difficult for the driver to identify; if the laser light source is not properly controlled, it may cause safety risks to the driver's vision or eyes; smoke is easily affected by wind speed, and its shape and stability are poor.

[0020] In this embodiment, as Figure 1 and Figure 2As shown, a flexible barrier includes a mounting base 3, on which a housing 1 is mounted. The door of the housing 1 automatically pops open. An air inlet 2 is provided at the lower end of the housing 1, and the air inlet 2 is connected to a high-pressure blower. The high-pressure blower is electrically connected to a control system. A barrier body 4 is provided inside the housing 1, and the entrance of the barrier body 4 is connected to the air inlet 2. In the event of a natural disaster or traffic accident, the control system controls the high-pressure blower to quickly inflate the barrier body 4, causing it to unfold horizontally under aerodynamic tension and suspend at a height of 0.8–1.5 m above the ground. Through reflective materials or active light-emitting units, it forms a continuous suspended flexible barrier strip covering a standard 3.75 m wide lane, thereby achieving active warning and traffic blocking for vehicles, and preventing collision injuries to drivers who cannot stop within a reasonable response time. Specifically, the system uses high-pressure fans deployed on both sides of the road to eject air at high speed and direction. Utilizing the fluid pressure-velocity relationship described by Bernoulli's equation, a negative pressure suction is created in the nozzle's contraction section, allowing the barrier body 4 to inflate and maintain a suspended or semi-suspended state in a very short time. The surface of the barrier body 4 is covered with highly retroreflective material and LED light strips. Under the continuous support of the fan airflow, it rapidly expands and stabilizes, maintaining a horizontal shape within a height range of 0.8–1.5 m above the ground. This effectively covers a standard 3.75 m wide lane, forming a visual "pneumatic curtain wall," thus creating a three-dimensional visual warning zone. This enhances the driver's visual perception, providing both a flexible buffer for vehicles and a high-brightness warning effect.

[0021] Furthermore, the barrier body 4 is symmetrically arranged on both sides of the road. Specifically, to avoid crosswind interference, the airflow of the high-pressure fans on both sides is interlocked through phase difference control.

[0022] ;

[0023] in, This refers to the lateral wind speed. The operating frequency of the fan. The spacing between the wind turbine stations. By adjusting the operating phase of the high-pressure wind turbines on the left and right sides, a dynamic airflow barrier is formed, enhancing the structural stability of the system in wind conditions of level 6 (10.8–13.8 m / s) and ensuring reliable operation under severe weather conditions.

[0024] Furthermore, the barrier body 4 includes a fiber reinforcement layer, a flow guiding layer, and a surface layer. The flow guiding layer is located between the fiber reinforcement layer and the surface layer, with the fiber reinforcement layer being the inner layer. Specifically, the fiber reinforcement layer enhances the tear resistance and weather resistance of the barrier body 4, ensuring its service life. Flexible optical fibers or LED light strips can also be attached to the fiber reinforcement layer. The flow guiding layer has several flow channels, whose main function is to ensure gas transmission efficiency and optimize aerodynamic response. The surface layer is equipped with directional reflective units, whose optical orientation forms a 15-30° angle with the lane direction. In other words, by attaching flexible optical fibers or LED light strips to the fiber reinforcement layer and providing directional reflective units on the surface layer, the barrier body 4 maintains excellent visibility at night and in rainy / foggy conditions, allowing drivers to recognize warning information from a distance.

[0025] In this embodiment, the control system includes a sensor group and a controller. The sensor group is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the high-pressure blower. Specifically, the sensor group, controller, and high-pressure blower are all powered by solar photovoltaic panels and high-density battery packs, with the two power supply lines operating independently. The communication link between the sensor group, controller, and high-pressure blower can use 4G / 5G or dedicated transportation lines to achieve remote monitoring. This ensures that the system can still operate independently using local closed-loop control even in the event of communication interruption or power failure, guaranteeing reliability.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
