Description

Technical Field

[0001] This utility model relates to the field of traffic equipment, specifically a traffic diversion device. Background Technology

[0002] At traffic junctions such as main urban roads, bridge entrances, and tunnel entrances, height-restricted traffic control devices are core facilities for separating vehicles of different heights, ensuring road structural safety, and maintaining traffic order. By installing adjustable height restriction mechanisms, they guide oversized vehicles such as large buses and trucks into designated lanes, preventing collisions with low-rise bridges, tunnels, or pipelines, while simultaneously ensuring the passage efficiency of smaller vehicles. This is of great significance in alleviating traffic congestion and reducing the accident rate.

[0003] With the development of intelligent transportation, adjustable height-limiting traffic guidance devices are gradually replacing traditional fixed height-limiting poles. For example, the traffic guidance device disclosed in patent CN 223269133 U uses a motor-driven gear structure to adjust the height of the box, adapting to the height restrictions of different lanes. Furthermore, the box can be rotated to reduce collision damage, representing a significant improvement over traditional devices. However, this device still has a weakness in wind resistance stability: the box relies on internal counterweights to maintain its vertical position. In severe weather conditions such as strong winds and convection, the wind can easily push the box to rotate around the crossbar, causing a deviation between the bottom of the box and the actual height restriction on the ground. This problem is particularly pronounced in windy areas such as coastal areas and elevated roads, making it difficult for existing devices to balance adjustment flexibility with wind resistance stability.

[0004] Therefore, developing a traffic diversion device with collision buffering function and the ability to maintain the vertical stability of the container in windy weather has become an urgent need to solve the industry's pain points. Utility Model Content

[0005] The purpose of this invention is to provide a traffic diversion device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A traffic diversion device includes a pair of uprights and a crossbar fixedly installed between the two uprights. Multiple height restriction signs are evenly spaced on the crossbar, each height restriction sign being rotatable via bearings. Each height restriction sign contains a counterweight and an elastic braking assembly. The elastic braking assembly includes a fixed ring, a movable ring, a spring, a telescopic rod, a brake disc, protrusions, a fixed disc, and a pushing unit. The fixed disc is movably fitted onto the crossbar and fixedly connected to the inner wall of the height restriction sign. The fixed ring is fixedly installed on the crossbar's body inside the height restriction sign. A movable ring is installed on the side of the fixed ring near the fixed disc via multiple springs. A telescopic rod is installed inside each spring, with one end fixedly connected to the movable ring and the other end movably inserted into the fixed ring. The brake disc is fixedly fitted onto the movable ring, and multiple hemispherical protrusions are installed on the sides of both the brake disc and the fixed disc. The pushing unit provides power for the brake disc to move towards the fixed disc.

[0008] As a further embodiment of this utility model: the elastic braking assembly is provided in two sets, and the two sets of elastic braking assemblies are symmetrically installed inside the height restriction sign.

[0009] As a further embodiment of this invention, the inner ring of the movable ring is also arrayed with multiple ball bearings.

[0010] As a further embodiment of this utility model: the pushing unit includes an electromagnet fixedly installed on the side of the fixed ring, a magnetic ring fixedly installed on the side of the movable ring, and a power supply module for energizing the electromagnet, with the electromagnet and the magnetic ring being arranged correspondingly.

[0011] As a further embodiment of this utility model: the power supply module includes a rotor, rotor arms, air cups, a rotating shaft, a winding drum, a copper coil, and a capacitor. The rotor is rotatably mounted on the upright via the rotating shaft. Multiple rotor arms are fixedly mounted on the rotor, and air cups are mounted on the rotor arms. Multiple magnetic materials are fixedly mounted on the shaft inside the upright. The winding drum is fixedly mounted inside the upright via a mounting rod. The winding drum is sleeved outside the rotating shaft, and a copper coil is wound on the winding drum. The copper coil is connected to a capacitor installed inside the crossbar via an electric wire. The capacitor is electrically connected to an electromagnet.

[0012] As a further embodiment of this utility model, a camera is also embedded in the side wall of the height restriction sign.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention effectively solves the core contradiction of traditional height restriction devices, which struggle to balance wind resistance and collision safety, through an innovative design of "wind-adaptive braking + collision buffering." In terms of wind resistance, the device utilizes a wind-powered self-generated electricity system to dynamically adjust the braking force: the wind cup rotates with the wind, driving magnetic material to cut copper coils and generate electricity. The current is stored in a capacitor and then powers an electromagnet. The stronger the wind, the higher the power generation efficiency, and the stronger the repulsive force between the electromagnet and the magnetic ring. This results in a stronger braking force, effectively preventing the height restriction sign from being blown away by strong winds. Furthermore, no external power supply is required throughout the process, achieving a balance between energy saving and precise response. In terms of buffering, when there is no wind or a light breeze, the spring-supported movable ring is in its initial position, the protrusion is not tightly fitted, and the height restriction sign can rotate freely. Upon collision with a vehicle, the relative sliding of the hemispherical protrusion causes the height restriction sign to rotate slowly, dissipating the force and preventing rigid collisions that could damage the device or the vehicle.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Example 1

[0025] Please see Figure 1-7 A traffic diversion device includes a pair of uprights 1 and a crossbar 2 fixedly installed between the two uprights 1. Multiple height restriction signs 3 are installed at equal intervals on the crossbar 2. The height restriction signs 3 are rotatably mounted by bearings, and a counterweight 4 is installed inside the height restriction sign 3. The uprights 1 are fixed to both sides of the road to provide stable support for the crossbar 2, which is suitable for multi-lane diversion scenarios. The crossbar 2 carries the height restriction signs 3 to ensure that the height restriction mechanism of each lane works independently. The height restriction signs 3 achieve collision buffering through the rotation of the bearings, and the counterweight 4 maintains its vertical state when there is no wind, ensuring the accuracy of the basic height restriction.

[0026] The height restriction sign 3 is also equipped with an elastic braking assembly, which includes a fixed ring 5, a movable ring 6, a spring 7, a telescopic rod 8, a brake disc 9, a protrusion 10, a fixed disc 11, and a pushing unit. The fixed disc 11 is movably sleeved on the crossbar 2 and fixedly connected to the inner wall of the height restriction sign 3. The fixed ring 5 is fixedly installed on the crossbar 2 inside the height restriction sign 3. The movable ring 6 is installed on the side of the fixed ring 5 near the fixed disc 11 via multiple springs 7. The telescopic rod 8 is installed inside the springs 7. One end of the telescopic rod 8 is fixedly connected to the movable ring 6, and the other end is movably inserted into the fixed ring 5. The moving disc 9 is fixedly sleeved on the movable ring 6, and multiple hemispherical protrusions 10 are installed on the side of the brake disc 9 and the side of the fixed disc 11. The fixed disc 11 rotates synchronously with the height restriction sign 3, and the fixed ring 5 provides a fixed reference for the braking structure. The spring 7 and the telescopic rod 8 cooperate to support the movable ring 6, and the telescopic rod 8 prevents the spring 7 from shifting when compressed. When the brake disc 9 and the hemispherical protrusions 10 on the fixed disc 11 are misaligned, frictional braking force is generated, which not only prevents the height restriction sign 3 from rotating due to strong winds, but also retains rotation buffer space during collisions, solving the problem of difficulty in balancing wind resistance and buffering in the prior art.

[0027] The propulsion unit is used to provide power for the movement of the brake disc 9 towards the fixed disc 11. The propulsion unit can adjust the braking force according to the wind force to achieve adaptive adjustment of wind resistance performance.

[0028] Example 2

[0029] Please see Figure 3 Two sets of elastic braking components are provided, and the two sets of elastic braking components are symmetrically installed inside the height restriction sign 3. The symmetrical layout makes the height restriction sign 3 bear force evenly, avoids rotational deviation caused by unilateral braking, and further improves wind resistance stability and collision buffer smoothness.

[0030] Example 3

[0031] Please see Figure 6 and Figure 7The inner ring of the movable ring 6 is also equipped with an array of multiple balls 12. The balls 12 convert the sliding friction between the movable ring 6 and the crossbar 2 into rolling friction, which greatly reduces its motion resistance and ensures that the brake disc 9 responds quickly with the push unit, avoiding braking lag when the wind force changes suddenly.

[0032] Example 4

[0033] Please see Figure 3 and Figure 4 The driving unit includes an electromagnet 13 fixedly installed on the side of the fixed ring 5, a magnetic ring 14 fixedly installed on the side of the movable ring 6, and a power supply module for energizing the electromagnet 13. The electromagnet 13 and the magnetic ring 14 are arranged correspondingly. When the electromagnet is energized, it generates a repulsive force with the magnetic ring, which pushes the movable ring 6 to drive the brake disc 9 closer to the fixed disc 11, thereby achieving the misalignment braking of the protrusion 10. The magnitude of the repulsive force is adjusted according to the change of current to adapt to different wind intensities.

[0034] Example 5

[0035] Please see Figure 2 and Figure 5 The power supply module includes a rotor 15, rotor arms 16, wind cups 17, a rotating shaft, a winding drum 18, a copper coil 19, and a capacitor 20. The rotor 15 is rotatably mounted on the upright 1 via the rotating shaft. Multiple rotor arms 16 are fixedly mounted on the rotor 15, and wind cups 17 are mounted on the rotor arms 16. Multiple magnetic materials 21 are fixedly mounted on the shaft inside the upright 1. The winding drum 18 is fixedly mounted inside the upright 1 via a mounting rod and is sleeved outside the rotating shaft. A copper coil 19 is wound on the winding drum 18. The copper coil 19 is connected to the capacitor 20 set inside the crossbar 2 via wires. The capacitor 20 is electrically connected to the electromagnet 13. The wind cups 17 rotate with the wind, causing the rotating shaft and the magnetic materials 21 to cut the copper coil 19 and generate an induced current. After being stored in the capacitor 20, the current supplies power to the electromagnet 13. The stronger the wind, the higher the power generation efficiency and the stronger the repulsive force, achieving automatic adaptation of braking force with wind force. No external power supply is required, resulting in energy saving and precise response.

[0036] Example 6

[0037] Please see Figure 1 The height restriction sign 3 is also equipped with a camera 22 embedded in its side wall. The camera 22 can automatically capture images of illegally oversized vehicles when the height restriction sign 3 rotates due to a vehicle collision, preserve evidence, and enhance the intelligent management capabilities of the device.

[0038] Working principle:

[0039] In calm or lightly windy weather, the counterweight 4 maintains the height restriction sign 3 in a vertical position, the spring 7 supports the movable ring 6 in its initial position, and the brake disc 9 and the protrusion 10 on the fixed disc 11 are not tightly fitted, allowing the height restriction sign 3 to rotate freely to cope with possible collisions. When encountering strong winds, the wind cup 17 is driven by the wind force to rotate the rotor 15 and the shaft. The magnetic material 21 cuts the copper coil 19 to generate current, which is stored in the capacitor 20. When the electromagnet 13 is energized, it generates a repulsive force with the magnetic ring 14, pushing the movable ring 6 to compress the spring 7 and move towards the fixed disc 11. The ball bearing 12 reduces the resistance to movement, and the brake disc 9 and the hemispherical protrusion 10 on the fixed disc 11 are misaligned to generate braking force. The stronger the wind, the stronger the repulsive force and the more sufficient the braking force, effectively preventing the height restriction sign 3 from rotating and deviating. If a vehicle collides with the height restriction sign 3, the hemispherical structure of the protrusion 10 can slide relative to it when subjected to force, allowing the height restriction sign 3 to rotate slowly to buffer the impact and avoid rigid collision damage; at the same time, the camera 22 captures images of the violating vehicle. After the strong wind dissipates, the electromagnet 13 is de-energized, the spring 7 pushes the movable ring 6 to reset, the braking force is released, and the counterweight 4 drives the height restriction sign 3 to return to vertical, taking into account both wind resistance stability and collision safety throughout the process.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
