Technical Field

[0001] This invention relates to the field of highways, specifically a highway safety early warning device. Background Technology

[0002] A highway is a type of road characterized by two or more lanes in each direction, two-way separation, fully controlled entrances and exits, enclosed access on both sides, and grade-separated interchanges. It has higher speed limits than ordinary roads, handles larger traffic volumes, and offers greater economic and social benefits.

[0003] When vehicles are traveling on highways, they need to use safety warning devices to warn other vehicles. However, current warning devices require the installation of detection racks, and these devices do not need to work under normal weather conditions. This results in an excessive number of monitoring racks being installed on highways, leading to a waste of resources. Summary of the Invention

A first connecting rod is fixedly installed on the first slider and is slidably connected to the second partition. A conductive protrusion is installed on the first connecting rod located at the bottom of the second partition, and the conductive protrusion is connected to the processor via a first wire. A power supply battery is provided at the bottom of the connecting frame located between the first partitions. The power supply battery is connected to the conductive groove via a second wire. The conductive groove is located on the bottom inner wall of the connecting frame and is located at the outer end of the connecting frame. A second connecting groove is provided at the bottom outer end of the warning plate. A third partition is installed on the second connecting groove. A second connecting rod is slidably connected to the third partition. A second slider is provided at the top of the second connecting rod. The top of the second slider is connected to the second connecting groove via a return spring. A warning light is installed on the second connecting rod located at the bottom of the third partition.

[0007] Preferably, the installation mechanism includes a connecting frame disposed on the top of the connecting frame, with installation components disposed at both ends of the top of the connecting frame, a sealing box fixedly installed at the bottom of the connecting frame, rotation monitoring components installed on the outer walls at both ends of the sealing box, and a first cleaning pad installed on the connecting frame located on top of the rotation monitoring components; a second rotating rod is rotatably mounted on the sealing box, and a first driving component for driving the second rotating rod to rotate is installed inside the sealing box; the second rotating rod located outside the sealing box is fixedly connected to the connecting frame, and the connecting frame and the sealing box are interconnected through a first guide component.

[0008] Preferably, the mounting assembly includes a connecting column fixedly connected to the connecting frame, a first mounting ear fixedly mounted on the top of the connecting column, a second mounting ear provided on the top of the first mounting ear, and the second mounting ear and the first mounting ear connected by mounting bolts.

[0009] Preferably, the rotation monitoring component includes a first motor mounted on the inner wall of the sealed box, a first rotating rod mounted on the motor shaft of the first motor, the first rotating rod being rotatably connected to the connecting frame, an mounting cylinder mounted on the first rotating rod, and a monitoring probe mounted on the mounting cylinder.

[0010] Preferably, the first guide component includes a guide protrusion fixedly installed on the outer wall of the sealing box, the bottom of the guide protrusion being disposed inside a first guide groove, and the first guide groove being formed on the outer wall of the connecting frame.

[0011] Preferably, the second drive assembly includes a fixing block connected to the inner wall of the connecting frame, a third motor is fixedly mounted on the fixing block, a first pulley is mounted on the motor shaft of the third motor, the first pulley is connected to a second pulley via a belt, and the second pulley is connected to a rotating shaft.

[0012] Preferably, the elastic connection assembly includes a guide rod that is fixedly connected to the second partition and the first connecting groove, the guide rod is slidably connected to the first slider, and a connecting spring is installed on the guide rod located at the top of the first slider.

[0013] Preferably, the second guide component includes a guide block fixedly connected to the warning plate, the guide block being inserted into the second guide groove, the second guide groove being formed on the top inner wall of the connecting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses a highway indicator plate on the surface of the mounting frame to indicate vehicles traveling on the highway. By installing the warning mechanism inside the connecting frame, it facilitates the combination of the highway indicator plate and the warning mechanism, effectively reducing the need for monitoring frames on highways to install the warning device, thus saving resources. The present invention uses a second drive assembly to drive a rotating shaft, which in turn drives a drive gear to rotate. The drive gear drives a meshing rack plate to move. The rack plate, through a moving plate, moves the warning plate outward. During this outward movement, when the second connecting groove moves to the outside of the connecting frame, the elastic force generated by the compression of the return spring pushes the second slider downward. The second slider, through the second connecting rod, moves the warning light downward to the bottom of the second connecting groove, thus providing a warning to surrounding vehicles. Meanwhile, the warning plate moves to the inner wall of the connecting frame. Under the constraint of the connecting frame, the warning light retracts into the second connecting groove, thus facilitating the automatic retraction and extension of the warning light. The warning plate continues to move outwards until the first connecting groove reaches the conductive groove. The elastic connecting component pushes the first slider to move, which in turn moves the first connecting rod downwards. The first connecting rod then pushes the conductive protrusion downwards to contact the conductive groove. The power supply battery powers the processor through the second wire, the conductive groove, the conductive protrusion, and the first wire. The processor controls the warning display screen to provide warnings to vehicles. Furthermore, this invention eliminates the need for a power switch to control the processor's power supply, effectively facilitating the automatic power control of the warning device. During the contact between the conductive protrusion and the conductive groove, the conductive protrusion and the conductive groove brake the warning plate, thereby controlling its movement and facilitating warnings to vehicles traveling on highways.

A first cleaning pad 25 is installed on the connecting frame 21 located on top of the rotation monitoring components 24. A second rotating rod 26 is rotatably mounted on the sealing box 23. A first driving component 27 for driving the second rotating rod 26 to rotate is installed inside the sealing box 23. The second rotating rod 26 located outside the sealing box 23 is fixedly connected to the connecting frame 1. The connection between the connecting frame 1 and the sealing box 23... The components are interconnected via the first guide assembly 28. The connecting frame 21 is connected to the monitoring frame installed on the highway via the mounting assembly 22. The monitoring equipment is rotated by rotating the monitoring assembly 24. When the monitoring equipment rotates to the first cleaning pad 25, the first cleaning pad 25 cleans the monitoring equipment, thus facilitating the monitoring of the surrounding environment. The second rotating rod 26 is driven to rotate via the first drive assembly 27. The second rotating rod 26 drives the connecting frame 1 to rotate and adjust its orientation under the guidance of the first guide assembly 28, thus facilitating the installation and orientation adjustment of the warning device, and thus facilitating the warning of vehicles traveling on the highway.

[0030] See Figure 2In one embodiment of the present invention, the mounting assembly 22 includes a connecting column 221 fixedly connected to the connecting frame 21.

During the rotation of the connecting frame 1, the first guide groove 282 rotates under the guidance of the guide protrusion 281. This can realize the bearing treatment and guiding rotation treatment of the connecting frame 1, thereby ensuring the smooth rotation of the connecting frame 1.

[0035] See Figure 6 In one embodiment of the present invention, a second cleaning pad 34 is installed on the inner wall of the openings at both ends of the connecting frame 1. The second cleaning pad 34 is used to wipe the warning display screen 33. The setting of the second cleaning pad 34 can clean the surface of the moving warning display screen 33, thereby ensuring the cleanliness of the warning display screen 33.

[0036] See Figure 3 and Figure 6 In one embodiment of the present invention, the second driving component 39 includes a fixing block 391 connected to the inner wall of the connecting frame 1.

The second pulley 395 drives the rotating shaft 38 to rotate.

[0037] See Figure 4 In one embodiment of the present invention, the elastic connection assembly 313 includes a guide rod 3131 fixedly connected to the second partition 312 and the first connecting groove 311. The guide rod 3131 is slidably connected to the first slider 314. A connecting spring 3132 is installed on the guide rod 3131 located at the top of the first slider 314. The elastic force generated by the compression of the connecting spring 3132 pushes the first slider 314 to move and adjust its position under the guidance of the guide rod 3131.

[0038] See Figure 3 In one embodiment of the present invention, the second guide component 327 includes a guide block 3271 fixedly connected to the warning plate 32. The guide block 3271 is inserted into the second guide groove 3272, which is formed on the top inner wall of the connecting frame 1. During the movement of the warning plate 32, the guide block 3271 moves under the guidance of the second guide groove 3272, thereby ensuring that the warning plate 32 moves smoothly on the connecting frame 1.

[0039] Working Principle: This invention connects the early warning device to the highway height monitoring frame via the mounting component 22. A second motor 271 drives the drive gear 272, which in turn rotates the meshing driven gear 273. The driven gear 273 then rotates the second rotating rod 26, which in turn adjusts the orientation of the connecting frame 1 under the guidance of the first guide component 28. A third motor 392 drives the first pulley 393 to rotate. The first pulley 393, via a belt 394, drives the second pulley 395 to rotate. The second pulley 395 rotates the rotating shaft 38, which in turn drives the drive gear 37. The drive gear 37 then rotates the meshing rack plate 36, which in turn moves the moving plate 35. The moving plate 35 then moves the early warning plate 32 under the guidance of the second guide component 327. During the rotation of the early warning plate 32, a second connection is formed at the bottom of the early warning plate 32. The groove 321 moves out onto the outer wall of the connecting frame 1. The elastic force generated by the compression of the return spring 325 pushes the warning light 326 out to the outside of the second connecting groove 321. The warning light 326 provides warning processing for the moving vehicle. During the outward movement of the warning plate 32, when the first connecting groove 311 moves to the conductive groove 318, the elastic force generated by the compression of the connecting spring 3132 pushes the first slider 314 downward. The first slider 314 drives the first connecting rod 315 to drive the conductive protrusion 316 downward to contact the conductive groove 318. The power supply battery 320 provides power to the processor 310 through the second wire 319, the conductive groove 318, the conductive protrusion 316 and the first wire 317. The processor 310 controls the warning display screen 33 to provide warning processing for the moving vehicle. This makes it convenient to provide warning processing for vehicles traveling on highways in severe weather conditions.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
