Description

Technical Field

[0001] The present invention relates to the technical field of road traffic warning technology, and more particularly, to a road warning device. Background Art

[0002] During road construction, it's necessary to install warning devices along curves to ensure traffic safety and improve efficiency. They also serve as a reminder for drivers to slow down and drive safely. This is especially true on curves, where centrifugal force increases. Excessive speed can easily lead to accidents like skidding and rollovers. Curve warning devices can use sound, light, and text to alert drivers of upcoming curves, prompting them to slow down and reduce accidents caused by excessive speed.

[0003] In existing public literature, patent publication number CN116623580A discloses a road traffic warning device and method. This technology uses a main detection unit to detect abnormal road conditions, triggering a mobile detection vehicle to slide along the road guardrail. When passing each column, the transmission member pushes the guide column to rotate, causing the warning plate to rotate upward, with the front of the warning plate facing the direction of oncoming vehicles. When the main detection unit and the auxiliary detection unit no longer detect abnormal road conditions, the mobile detection vehicle moves back to rotate the warning plate downward and reset, achieving the effect of balancing the immediacy of warning in road traffic warning with the reasonable and controllable warning cost. However, this technology still has the following drawbacks.

[0004] In road warning, it can play an early warning and warning role in ordinary road areas, but it has obvious shortcomings in the curved area. Due to its own structural characteristics, the curve has a large blind spot. When a traffic accident occurs in a curve, the existing early warning means are difficult to carry out large-scale horizontal and vertical synchronous displacement warnings for vehicles and personnel on both sides about to enter the curve. This leads to a limited area that the warning can cover, and it is difficult to reach more objects affected by the accident. Due to this limitation, the warning range is greatly reduced and the road warning effect is poor. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solutions: A road warning device includes a road upright box and a wireless controller, wherein a warning display screen is fixedly connected to one side of the road upright box, a micro-retractable electric cylinder is fixedly connected to the inner wall of the road upright box, and a double-sided displacement warning component is installed at the retracted end of the micro-retractable electric cylinder; the double-sided displacement warning component includes a linkage bar fixedly installed at the retracted end of the micro-retractable electric cylinder, and both ends of the linkage bar are fixedly connected to steel pull ropes, one end of two steel pull ropes are fixedly connected to connecting blocks, the outer walls of the two connecting blocks are fixedly connected to a rotating groove shaft, and the two rotating groove shafts are rotatably connected to the road upright box, and the inner walls of the two rotating groove shafts are respectively rotatably connected to a group of warning lasers, the laser beams of one group of warning lasers are tilted downward, and the laser beams of the other group of warning lasers are tilted upward; one side of the warning laser is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is rotatably connected to a shaft ring, and the shaft ring is fixedly connected to the rotating groove shaft.

[0006] Preferably, the two steel pull ropes and linkage bar are both slidably connected to the road upright box, the steel pull rope is slidably connected to the trough shaft, and the micro-retracting electric cylinder is electrically connected to the wireless controller. A linkage block is fixedly connected to the outer wall of the trough shaft, located on one side of the connection block. A straightening rope is fixedly connected to one side of the linkage block, and the straightening rope is slidably connected to the road upright box. An elastic bar is fixedly connected between the two straightening ropes.

[0007] During operation, a micro-retracting electric cylinder drives the linkage bar to retract and move downward. This linkage bar then simultaneously moves one end of two steel cables downward. The cables slide along the outer wall of the positioning roller. The other end of the cable drives the connecting block to rotate clockwise, while the other end of the other cable drives the other connecting block to rotate counterclockwise. The trough shaft drives the linkage block to rotate clockwise, while the other end of the stretched cable pulls the spring bar. The two stretched cables simultaneously apply tension to the spring bar. The trough shaft drives the linkage shaft to rotate clockwise within the road vertical box. The shaft ring drives the shaft to rotate clockwise, which in turn drives the warning lasers to rotate clockwise. The warning laser beams generated by the two warning lasers are then aligned to form a cross-warning state. This allows the intersecting beams generated by the two warning lasers within the trough shaft to rotate clockwise, while the intersecting beams generated by the two intersecting warning lasers within the other trough shaft can also rotate counterclockwise.

[0008] Preferably, a circumferential vertical displacement warning component is provided between the warning laser and the shaft ring; the circumferential vertical displacement warning component includes a sleeve frame arranged between the warning laser and the shaft ring, the sleeve frame is fixedly connected to the rotating shaft, a shift slide is provided on one side of the rotating shaft, the shift slide and the sleeve frame are slidably connected, one end of the shift slide is installed with a changing bar, multiple shift slides are fixedly connected to the changing bar, the changing bar is slidably connected to the rotation groove shaft, the top of the changing bar is fixedly connected to a rotating block, the outer wall of the changing bar is slidably connected to the sliding frame, and the sliding frame is fixedly connected to the rotation groove shaft; one side of the rotating block is fixedly connected to a wave column, each of the rotation groove shafts is provided with a wave ring, the inner wall of the wave ring is provided with multiple V-shaped tooth grooves, and the wave column is slidably connected to the wave ring to which the V-shaped tooth grooves belong.

[0009] The shifting slide is slidably connected to the warning laser. The outer wall of the shifting slide and the inner wall of the sleeve are both smooth. The rotating block is slidably connected to the trough shaft, with multiple V-shaped tooth grooves arranged equidistantly along a circular arc path. A limit ring is fixedly mounted on the top of the wave ring. A reinforcement bar is fixedly connected between the two limit rings, and the reinforcement bar is fixedly connected to the road vertical box. A top cover is fixedly connected to the top of the road vertical box near its edge. A camera is fixedly mounted on the top surface of the top cover and is electrically connected to the wireless controller. A linkage shaft is fixedly connected to the bottom end of the trough shaft, concentrically, and rotatably connected to the road vertical box. Positioning rollers are fixedly connected to both sides of the inner wall of the road vertical box. The outer walls of the positioning rollers are slidably connected to the outer wall of the steel pull rope. The outer walls of the positioning rollers are smooth. The wireless controller is fixed to the outer wall of the micro-retracting electric cylinder and is fixedly connected to the road vertical box.

[0010] During operation, as the trough shaft rotates clockwise, the sliding frame drives the deflection bar to rotate clockwise, while the rotating block drives the wave column to rotate clockwise. The wave column then moves upward along the V-shaped tooth groove, driving the rotating block upward. The deflection bar drives multiple deflection slides to move synchronously upward, while the sleeve frame drives the rotating shaft in a vertical counterclockwise rotation. The rotating shaft rotates vertically counterclockwise on the inner wall of the shaft ring, enabling the two sets of warning lasers to provide circumferential vertical displacement warning. When the wave column moves along the limit ring between the two wave rings into the next V-shaped tooth groove, the wave column drives the rotating block downward, the deflection bar drives multiple deflection slides downward, and the deflection slides drive the sleeve frame in a vertical clockwise rotation. As the wave column continues its circular movement within the multiple V-shaped tooth grooves within the wave ring, the intersecting beams generated by the two sets of cross-warning lasers within the trough shaft provide a circular reciprocating vertical rotational displacement warning.

[0011] Technical effects and advantages of the present invention: 1. The present invention uses a double-sided displacement warning component, and a micro-contracting electric cylinder drives the linkage bar to move downward, and the connecting blocks are linked through the steel pull rope to make the rotating slot shaft rotate horizontally clockwise, and the other rotating slot shaft can synchronously rotate horizontally counterclockwise. There are two groups of warning lasers in the rotating slot shaft, one group of lasers is tilted downward, and the other group is tilted upward, forming a cross warning state. The cross light beams in one rotating slot shaft rotate horizontally clockwise, and the cross light beams in the other rotating slot shaft rotate horizontally counterclockwise, which can provide a large area of ​​displacement warning light beams to both sides in the middle of the curve, effectively expanding the warning range, realizing cross displacement warning on both sides of the curve, and enhancing the warning effect on vehicles and personnel on both sides in the event of a curve accident.

[0012] 2. The present invention uses a circumferential vertical displacement warning component, so that when the rotating groove shaft rotates horizontally clockwise, the sliding frame and the change-direction bar rotate synchronously and efficiently, and the wave column moves upward along the circumference of the V-shaped tooth groove, thereby causing the two groups of warning lasers to rotate vertically counterclockwise to achieve warning. When the wave column moves to the next V-shaped tooth groove, it drives the components to move downward. As the wave column moves circumferentially in multiple V-shaped tooth grooves, the cross light beams generated by the two groups of cross warning lasers can perform vertical reciprocating rotation displacement warning on the circumferential path, thereby expanding the warning range and effect, and can more comprehensively remind vehicles and personnel inside and outside the curve, enhance road warning capabilities, and enhance the warning effect on vehicles and personnel on both sides in the event of a curve accident.

[0013] 3. The present invention uses a wireless controller to activate the micro-contracting electric cylinder to drive the linkage bar to move up and reset. Under the action of the elastic force of the elastic bar, the straightened rope is reset horizontally counterclockwise, and the other straightened rope is reset horizontally clockwise. The linkage block resets the rotating slot shaft horizontally counterclockwise, so that the warning laser returns to its initial position. At the same time, the rotating slot shaft drives the sliding frame to move back and forth vertically along multiple V-shaped tooth grooves under the cooperation of the elastic force of the elastic bar, thereby driving the warning laser to rotate back and forth vertically. In this way, the two rotating slot shafts are reset and displaced synchronously. During the reset process, the two groups of cross warning lasers inside the rotating slot shaft perform vertical reciprocating rotation and displacement warnings on a circular path, which improves the flexibility and comprehensiveness of the warning and enhances the road warning effect.

[0014] 4. This invention uses a single miniature retractable electric cylinder as a power source, achieving efficient synchronous linkage and significant energy and cost reduction advantages. After the miniature retractable electric cylinder is activated, the linkage bar moves upward, and the revolving slot shaft, assisted by the spring bar's rebound force, not only drives the early warning laser to reset horizontally counterclockwise but also synchronizes the sliding frame, causing the wave column to reciprocate vertically along the circumference of the V-shaped tooth groove, thereby driving the early warning laser to rotate vertically. Relying on a single power source, the two revolving slot shafts can work together to achieve complex displacement warnings for the cross warning laser, reducing the number of power devices, energy consumption, equipment costs, and improving the economic efficiency of the equipment.

[0035] In this embodiment, as shown in the attached Figure 3As shown, the wireless controller 28 is fixed on the outer wall of the micro-retractable electric cylinder 3, and the wireless controller 28 is fixedly connected to the road upright box 1 so that the wireless controller 28 can start the micro-retractable electric cylinder 3 and realize the driving operation of the micro-retractable electric cylinder 3. At the same time, the road upright box 1 can provide stable support force for the wireless controller 28.

[0036] The working principle of the road warning device of the present invention is as follows: First, when installing the device on a curve, the road upright box 1 is mounted on the exterior of the road fence on the left side of the curve. Bolts are pre-installed to secure the box 1, and the warning display screen 2 on the box 1 faces the middle of the mountainside at the curve. The box 1 supports a top cover 24, which in turn supports a camera 25. The camera 25 captures video of the curve. If an accident occurs on the curve, a wireless controller 28 displays a warning message indicating a traffic accident on the warning display screen 2, simultaneously activating the micro-retracting electric cylinder 3.

[0037] Secondly, when the present invention performs a bilateral cross-displacement warning, the micro-retracting electric cylinder 3 drives the linkage bar 4 to retract and move downward. The linkage bar 4 moves downward along the inner wall of the road upright box 1. The linkage bar 4 drives one end of two steel ropes 5 to move downward synchronously. The steel ropes 5 slide along the outer wall of the positioning roller 27. The other end of the steel rope 5 drives the connecting block 6 to rotate horizontally clockwise, while the other end of the other steel rope 5 drives the other connecting block 6 to rotate horizontally counterclockwise. In this way, the connecting block 6 drives the trough shaft 7 to rotate horizontally clockwise, which in turn drives the linkage block 11 to rotate horizontally clockwise. The linkage block 11 drives one end of the straightening rope 12 to rotate horizontally clockwise, while the other end of the straightening rope 12 pulls the spring bar 13. In this way, the two straight ropes 12 can synchronously provide tension to the elastic bar 13, and the elastic bar 13 generates a telescopic elastic force. Then the trough shaft 7 drives the linkage shaft 26 to rotate horizontally clockwise inside the road upright box 1, and the trough shaft 7 drives multiple shaft rings 10 to rotate horizontally clockwise, and the shaft rings 10 drive the rotating shaft 9 to rotate horizontally clockwise, and the rotating shaft 9 drives the early warning laser 8 to rotate horizontally clockwise.

[0038] Because the laser beams of one set of warning lasers 8 are tilted downward, while the laser beams of the other set of warning lasers 8 are tilted upward, the warning laser beams generated by the two sets of warning lasers 8 can form a cross warning state. In this way, the cross beams generated by the two sets of warning lasers 8 inside the rotating trough shaft 7 can rotate and shift laterally clockwise, while the cross beams generated by the two sets of crossing warning lasers 8 inside the other rotating trough shaft 7 can rotate and shift laterally counterclockwise. In this way, a large area of ​​displacement warning beam prompts can be provided from the middle of the curve to both sides of the curve, providing a cross displacement warning for both sides of the curve.

[0039] At the same time, when the present invention performs a circumferential vertical displacement warning, when the trough shaft 7 rotates horizontally clockwise, the trough shaft 7 will drive the slide frame 18 to rotate horizontally clockwise, the slide frame 18 will drive the changing bar 16 to rotate horizontally clockwise, the changing bar 16 will drive the rotating block 17 to rotate horizontally clockwise, and the rotating block 17 will drive the wave column 19 to rotate horizontally clockwise. At the same time, the road upright box 1 supports the reinforcement bar 23, the reinforcement bar 23 supports the limit ring 22, and the limit ring 22 provides support for the fluctuation ring 20, so that the fluctuation column 19 will move upward along the V-shaped tooth groove 21, so that the fluctuation column 19 drives the rotating block 17 to move upward in a circle, and the rotating block 17 drives the changing bar 16 to move upward in a circle along the inner wall of the sliding frame 18, and the changing bar 16 drives multiple displacement slides 15 to move upward synchronously, and the displacement slide 15 moves upward along the inner wall of the sleeve frame 14, and the sleeve frame 14 drives the rotating shaft 9 to rotate vertically counterclockwise, so that the rotating shaft 9 rotates vertically counterclockwise on the inner wall of the shaft ring 10, and the rotating shaft 9 drives the warning laser 8 to rotate vertically counterclockwise, so that the two groups of warning lasers 8 can perform circumferential vertical displacement warning.

[0040] When the wave column 19 moves along the limit between the limit ring 22 and the wave ring 20 to the inside of the next V-shaped tooth groove 21, the wave column 19 drives the rotating block 17 to move downward in a circular motion, which in turn drives the direction-changing bar 16 to move downward in a circular motion, which in turn drives the multiple position-changing slides 15 to move downward in a circular motion, which in turn drives the sleeve 14 to rotate vertically clockwise. In this way, as the wave column 19 continuously moves circularly within the multiple V-shaped tooth grooves 21 within the wave ring 20, the intersecting beams generated by the two sets of intersecting warning lasers 8 within the rotating slot shaft 7 can perform a vertical reciprocating rotational position warning along a circular path.

[0041] Finally, when the present invention resets and shifts, the wireless controller 28 activates the micro-retracting electric cylinder 3 to drive the linkage bar 4 upward. This causes the linkage bar 4 to move one end of each of the two steel pull ropes 5 upward. Under the action of the rebound force of the spring bar 13, the straightened rope 12 is reset horizontally counterclockwise, while the other straightened rope 12 is reset horizontally clockwise. In this way, the linkage block 11 drives the rotating shaft 7 to reset horizontally counterclockwise, the rotating shaft 7 drives the collar 10 to reset horizontally counterclockwise, the collar 10 drives the rotating shaft 9 to reset horizontally counterclockwise, and the rotating shaft 9 drives the warning laser 8 to reset horizontally counterclockwise.

[0042] At the same time, the rotating slot shaft 7 drives the sliding frame 18 to reset horizontally counterclockwise, the sliding frame 18 drives the changing bar 16 to reset the rotating block 17 horizontally counterclockwise, the rotating block 17 drives the wave column 19 to reset horizontally counterclockwise, the wave column 19 performs a circumferential vertical reciprocating motion along the multiple V-shaped tooth grooves 21, the wave column 19 drives the rotating block 17 to perform a circumferential vertical reciprocating motion, the changing bar 16 drives the shifting slide 15 to perform a circumferential vertical reciprocating motion, the shifting slide 15 drives the sleeve 14 to perform a vertical reciprocating rotation, the sleeve 14 drives the rotating shaft 9 to move vertically reciprocatingly, and the rotating shaft 9 drives the warning laser 8 to rotate vertically reciprocatingly. In this way, the two rotating slot shafts 7 can be reset and shifted synchronously, and at the same time, the cross-beams generated by the two sets of cross-warning lasers 8 inside the rotating slot shaft 7 can perform a vertical reciprocating rotation and displacement warning of the circumferential path during the reset process.
