[0037] The working principle of the road early warning device is as follows:

[0038] Firstly, when the road is installed, the road upright box 1 is first installed on the outside of the road fence on the left side of the curve, and is installed and fixed by bolt pre-buried, and the early warning display screen 2 on the road upright box 1 is directly opposite the middle area of the curve mountain. The road upright box 1 supports the top cover 24, the top cover 24 supports the camera 25, the camera 25 can collect the road video of the curve area, when the curve has an accident problem, the wireless controller 28 displays the warning text of the road traffic accident on the early warning display screen 2, and the wireless controller 28 starts the micro retractable cylinder 3.

[0039] Secondly, when the bilateral crossing displacement early warning is carried out, the micro retractable cylinder 3 drives the linkage strip 4 to retract and move downward, the linkage strip 4 moves downward along the inner wall of the road upright box 1, the linkage strip 4 drives one end of the two steel pull ropes 5 to move downward synchronously, the steel pull rope 5 slides along the outer wall of the positioning roller 27, the other end of the steel pull rope 5 drives the connection block 6 to rotate horizontally clockwise, and the other end of the other steel pull rope 5 drives the other connection block 6 to rotate horizontally counterclockwise. In this way, the connection block 6 drives the rotating groove shaft 7 to rotate horizontally clockwise, the rotating groove shaft 7 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, and the other end of the straightening rope 12 pulls the elastic strip 13. In this way, the two straightening ropes 12 can synchronously provide tension to the elastic strip 13, the elastic strip 13 generates elastic force, then the rotating groove shaft 7 drives the linkage shaft 26 to rotate horizontally clockwise inside the road upright box 1, the rotating groove shaft 7 drives the plurality of shaft rings 10 to rotate horizontally clockwise, the shaft ring 10 drives the rotating shaft 9 to rotate horizontally clockwise, and the rotating shaft 9 drives the early warning laser 8 to rotate horizontally clockwise.

[0040] Since the laser beam direction of one group of early warning lasers 8 is inclined downward, and the laser beam direction of the other group of early warning lasers 8 is inclined upward, the warning laser beams generated by the two groups of early warning lasers 8 can form a crossing warning state. In this way, the crossing beams generated by the two groups of early warning lasers 8 inside the rotating groove shaft 7 can rotate horizontally clockwise, and the crossing beams generated by the two groups of early warning lasers 8 inside the other rotating groove shaft 7 can rotate horizontally counterclockwise, so as to provide large-area displacement warning beam prompts to the two sides of the curve in the middle of the curve, and to early warn the bilateral crossing displacement of the curve.

[0041] Meanwhile, when the circumferential vertical displacement early warning is carried out, the rotating groove shaft 7 rotates clockwise in the transverse direction, the rotating groove shaft 7 drives the sliding frame 18 to rotate clockwise in the transverse direction, the sliding frame 18 drives the direction-changing strip 16 to rotate clockwise in the transverse direction, the direction-changing strip 16 drives the rotating block 17 to rotate clockwise in the transverse direction, and the rotating block 17 drives the undulating column 19 to rotate clockwise in the transverse direction. Meanwhile, the road vertical box 1 supports the reinforcing strip 23, the reinforcing strip 23 supports the limiting ring 22, and the limiting ring 22 provides support force for the undulating ring 20, so that the undulating column 19 moves upward along the V-shaped tooth groove 21, thereby the undulating column 19 drives the rotating block 17 to move upward along the inner wall of the sliding frame 18, the rotating block 17 drives the direction-changing strip 16 to move upward along the inner wall of the sliding frame 18, the direction-changing strip 16 drives the plurality of displacement slide columns 15 to move upward synchronously, the displacement slide column 15 moves upward along the inner wall of the sleeve frame 14, the sleeve frame 14 drives the rotating shaft 9 to rotate counterclockwise in the vertical direction, thereby the rotating shaft 9 rotates counterclockwise in the vertical direction in the inner wall of the shaft ring 10, and the rotating shaft 9 drives the early warning laser 8 to rotate counterclockwise in the vertical direction. Thus, the two groups of early warning lasers 8 can carry out circumferential vertical displacement early warning.

[0042] When the undulating column 19 moves to the inside of the next V-shaped tooth groove 21 between the limiting ring 22 and the undulating ring 20, the undulating column 19 drives the rotating block 17 to move downward in the circumferential direction, the rotating block 17 drives the direction-changing strip 16 to move downward in the circumferential direction, the direction-changing strip 16 drives the plurality of displacement slide columns 15 to move downward in the circumferential direction, and the displacement slide column 15 drives the sleeve frame 14 to rotate clockwise in the vertical direction. Thus, as the undulating column 19 continuously moves in the circumferential direction in the plurality of V-shaped tooth grooves 21 in the undulating ring 20, the intersecting light beams generated by the two groups of intersecting early warning lasers 8 in the rotating groove shaft 7 can carry out vertical reciprocating rotation displacement early warning in the circumferential path.

[0043] Finally, when the reset displacement is carried out, the miniature retracting electric cylinder 3 is started by the wireless controller 28 to drive the linkage strip 4 to move upward, the linkage strip 4 drives one end of the two steel pull ropes 5 to move upward, and under the action of the elastic force of the elastic strip 13, the straightening rope 12 can be reset counterclockwise in the transverse direction, and the other straightening rope 12 is reset clockwise in the transverse direction. Thus, the linkage block 11 drives the rotating groove shaft 7 to reset counterclockwise in the transverse direction, the rotating groove shaft 7 drives the shaft ring 10 to reset counterclockwise in the transverse direction, the shaft ring 10 drives the rotating shaft 9 to reset counterclockwise in the transverse direction, and the rotating shaft 9 drives the early warning laser 8 to reset counterclockwise in the transverse direction.

[0044] Meanwhile, the rotating groove shaft 7 drives the sliding frame 18 to reset laterally counterclockwise, the sliding frame 18 drives the direction-changing strip 16 to make the rotating block 17 reset laterally counterclockwise, the rotating block 17 drives the undulating column 19 to reset laterally counterclockwise, the undulating column 19 moves along the plurality of V-shaped tooth grooves 21 to move vertically and reciprocally in a circle, the undulating column 19 drives the rotating block 17 to make the direction-changing strip 16 move vertically and reciprocally in a circle, the direction-changing strip 16 drives the displacement sliding column 15 to move vertically and reciprocally in a circle, the displacement sliding column 15 drives the sleeve frame 14 to rotate vertically and reciprocally, the sleeve frame 14 drives the rotating shaft 9 to move vertically and reciprocally, and the rotating shaft 9 drives the early warning laser 8 to rotate vertically and reciprocally. In this way, the two rotating groove shafts 7 can reset and displace synchronously, and the intersecting light beams generated by the two groups of intersecting early warning lasers 8 in the rotating groove shaft 7 can rotate vertically and reciprocally in a circle during the resetting process.
