Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of safety fences, in particular to a collision-preventing fence for a police traffic barrier. BACKGROUND

[0002] The existing conventional police traffic barriers have the following technical defects: most of the existing barriers are simple rigid structures, such as concrete barriers (water horses), metal barriers, and simple fences. When a vehicle at high speed collides with such a barrier, a rigid collision occurs. Although this type of collision can stop the vehicle, the huge impact force will be transmitted to the vehicle body and the passengers in an instant, which can easily lead to a tragic accident of vehicle damage and death, and is often not conducive to subsequent case handling. The conventional barrier is a pure physical barrier and does not have any sensing, communication or recording capabilities. There are two contradictory aspects in the deployment. For example, the concrete barrier is stable, but its weight is huge, and it must rely on a crane or other heavy machinery for deployment and recovery, which is slow in response and cannot meet the rapid response requirements of temporary and emergency control tasks.

[0003] In summary, the existing technical solutions have the technical problems of single function, poor buffering capacity and low intelligence. SUMMARY

[0008] Preferably, the impact buffer structure comprises a flexible pad made of elastic material or variable energy-absorbing material, the flexible pad is fixedly installed on the reinforced beam, the outer wall of the flexible pad is in arc-shaped structure, a buffer air bag is arranged in the flexible pad, and the flexible pad is arranged on the impact surface of the protective fence.

[0009] Preferably, the sound and light warning structure comprises a warning lamp and a loudspeaker, the warning lamp and the loudspeaker are fixedly installed on the upper fence structure, the warning lamp is a flexible lamp strip, the loudspeaker is arranged on the rear side of the upper fence structure, and the output end of the loudspeaker faces the front of the upper fence structure.

[0010] Preferably, the counterweight structure comprises a counterweight box arranged in the lower slide structure, an injection pipe arranged on the counterweight box, and a drainage pipe arranged at the lower end of the side wall of the counterweight box.

[0011] Preferably, a damping rotating cylinder is rotatably installed on the side wall of the main frame, a wheel support is arranged on the damping rotating cylinder, an auxiliary wheel is rotatably installed on the wheel support, a brake tooth in wedge shape is arranged on the lower wall of the main frame.

[0012] Preferably, the intelligent control part comprises a video monitor, an impact sensor, a communication antenna, and a data recorder, the video monitor is arranged on the upper wall of the upper fence structure, the impact sensor is arranged in the impact buffer structure, a safety box is arranged on the rear wall of the lower slide structure, and the communication antenna and the data recorder are arranged in the safety box.

[0013] Preferably, an arc-shaped baffle is arranged on the front wall of the main frame.

[0014] Beneficial effects: the application provides a crash barrier of police traffic roadblock, the application absorbs the huge impact force through backward sliding and internal hydraulic device, converts the violent collision into deceleration parking, and maximizes the life safety of the people in the vehicle; can actively warn, remotely monitor, automatically alarm in the moment of being hit and transmit the on-site video and data back to the command center; records all the evidence, solves the problem of difficult evidence collection afterwards. It upgrades the roadblock from passive defense to active security; has a fillable and emptyable counterweight structure, so that the equipment is convenient to deploy and withdraw, has reliable stability during deployment, and has the following effects:

[0015] 1. By the sliding design of the upper fence structure along the slide, combined with the damping buffer structure (hydraulic damper and buffer spring), the instantaneous impact force of the vehicle collision is converted into a continuous deceleration process, greatly reducing the collision intensity; the collision buffer structure (flexible pad and buffer air bag) further absorbs the initial impact energy, prolongs the action time, maximizes the reduction of casualties and vehicle damage of the people in the vehicle, and solves the safety hidden danger caused by the "hard collision" of the traditional rigid roadblock.

[0016] 2.

[0017] 3. The counterweight structure (water / sand fillable counterweight box) realizes dynamic adjustment of the weight of the equipment: the weight is increased to improve the stability during deployment, and the weight is reduced to facilitate handling when withdrawn, balancing the contradiction between "stability and mobility" of the traditional roadblock; the auxiliary wheel cooperates with the brake tooth to facilitate single-person rapid movement and deployment, and to enhance the grip when being hit through the wedge-shaped brake tooth to prevent the roadblock from displacement or overturning.

[0018] 4. The three-prism-shaped protective fence and the reinforced beam design enhance the impact resistance, disperse the stress to avoid local damage; the arc-shaped baffle effectively resists the intentional damage of the vehicle equipped with a shovel-shaped device, and guarantees the overall protection effect of the roadblock; the cross-arranged hydraulic dampers form an anti-overturning torque, cooperate with the stable sliding of the inverted T-shaped slide and the guide slide block, and further improve the structural stability of the equipment under severe impact.

[0019] In summary, the application creates multiple designs through mechanical buffering, intelligent early warning and flexible deployment, which not only greatly improves the protection performance of the roadblock, but also realizes the leap from "passive interception" to "active security and intelligent control", and provides a safer, more efficient and intelligent solution for police traffic control, anti-terrorism and other scenes.

[0039] The embodiment is further provided with an arc-shaped baffle 901 on the front wall of the main frame 101; the arc-shaped baffle 901 is used to prevent the front of the vehicle from being provided with a shovel-shaped structure to lift the anti-collision fence; for some deliberate attacks, the vehicle may be provided with a wedge-shaped or shovel-shaped device in front, trying to overturn the product of the technical solution; the low arc-shaped baffle 901 can effectively prevent such attempts, which will block and guide the shovel-shaped structure to slide upwards, and finally make it hit the more solid main fence, forcing the attacking vehicle to collide in the way designed by the designer, thereby ensuring the effectiveness of the entire anti-collision system.

[0040] The detailed connection means is a technology known in the art; for example Figures 1-9 As shown, in the transportation and rapid deployment stage, it is confirmed that the counterweight box 601 of the anti-collision fence is in an empty state, at which time the total weight of the device is the lightest, facilitating transportation; the device is loaded onto a police truck or trailer; after the vehicle arrives at the preset control point, the anti-collision fence is unloaded; the operator lowers the auxiliary wheel 703 by rotating the damping rotary cylinder 701; at this time, the device can be easily moved like a trolley; using the auxiliary wheel 703, 1-2 police officers stably roll the anti-collision fence to the precise control position on the road; the design of the damping rotary cylinder 701 can prevent the moving speed from being too fast or the wheel from being accidentally retracted;

[0041] After positioning the device, reverse rotate the damping rotary cylinder 701 to retract the auxiliary wheel 703; as the wheel is retracted, the wedge-shaped brake teeth 704 at the bottom of the device will automatically contact the ground; use friction and wedge-shaped structure to prevent the device from sliding; open the injection pipe at the top of the counterweight box 601, and use a fire hose, a water pump, or direct pouring to quickly inject water (or sand) into the box; after filling, the total weight of the device increases sharply, obtaining strong bottom stability and anti-overturning ability; if a wider road needs to be blocked, multiple anti-collision fences can be deployed side by side and locked together using the preset connecting pieces to form an unbreakable defense line; confirm that the device is firmly in place, the brake teeth 704 are effectively in contact with the ground, and the counterweight is completed; turn on the total power switch in the safety box 802 at the rear wall of the lower slide structure 1 to power the intelligent control unit;

[0042] Start the audible and visual warning structure; the flexible LED warning lamp tube 501 on the upper fence structure 2 starts high-frequency flashing, and the loudspeaker 502 starts playing the preset warning voice, such as road closure ahead, no vehicle or alarm sound, for visual and auditory double-power warning to the direction of the oncoming vehicle; the command center or on-site commander can view the front road condition picture returned by the video monitor 801 in real time at this time, and monitor the device status; the device has entered the full-function on-duty state and passively waits for the impact event that may occur; the arc-shaped baffle 901 in front of it is also ready to prevent the vehicle bottom shovel-shaped attack;

[0043] According to the need, the cover can be covered on the device to achieve the concealment effect, prevent the suspect from being alert, and if a vehicle hits the barrier, the impact sensor in the impact buffer structure is triggered at the moment of vehicle impact; the intelligent control part immediately sends the impact alarm signal, impact data (speed, angle, force, etc.), GPS position and video recording of several seconds before and after the incident to the command center through the communication antenna; even if the network is interrupted, all key data has been completely saved in the data recorder in the safety box 802; after the incident, the device can be connected to download the most original and complete evidence materials;

[0044] The front part of the vehicle first hits the impact buffer structure in the front of the upper fence structure 2, that is, the flexible pad 401 and the buffer air bag 402 inside it. The flexible pad 401 and the air bag are quickly compressed and greatly deformed, greatly extending the action time of the impact force, thereby significantly reducing the peak value of the impact force; when the flexible buffer is compressed to the limit, the remaining, still huge impact kinetic energy is completely transmitted to the entire upper fence structure 2 through the reinforced beam 203; the guide slider 202 moves accurately and smoothly backward in the inverted T-shaped guide slide 102; the T-shaped slot structure firmly locks the slider, ensuring that the upper fence will never jump up or derail under impact; the buffer spring 302 is compressed, storing part of the kinetic energy in the form of elastic potential energy; the piston rod of the hydraulic damper 301 is pushed, and the hydraulic oil inside is forced through the narrow channel; this process generates extremely large and speed-proportional damping force, causing the vehicle to eventually stop; the cross-arranged hydraulic dampers 301 start to work; the upwardly inclined dampers are pushed, generating a downward force; the downwardly inclined dampers are pushed, generating an upward force, forming an anti-rollover torque that is completely opposite in direction to the rollover torque; the wedge-shaped brake teeth 704 will be inserted deeper into the ground under the action of horizontal thrust, further preventing the device from sliding as a whole; finally, the vehicle and the upper fence structure 2 will smoothly decelerate and stop moving together, completing a controlled and safe impact interception;

[0045] When the duty is over or the device needs to be transferred, first turn off the power of the intelligent control part; open the exhaust pipe valve at the lower end of the counterweight box 601 to quickly empty the water or sand inside the box; the device returns to the lightweight state; lower the auxiliary wheel 703 to make the device enter the movable state again; if the device only slides without structural damage, the upper fence structure 2 can be pushed back to the initial position of the slide by manpower or with the help of simple tools, and the buffer spring 302 will assist in resetting; push the device back to the transport vehicle and return to the base; after the device is stored, routine inspection and maintenance are carried out to ensure that it is always in the best standby state.
