[0019] The beneficial effects of the present invention are:

[0020] The highway road condition monitoring and early warning device described in the present invention, when actually used, when the camera detects that a vehicle is about to pass, a striking warning message is displayed on the display screen, and at the same time, the speaker emits a clear alarm sound, thereby reminding the passing vehicles to pay attention. At the same time, when encountering severe weather such as typhoons, the maintenance personnel can unscrew the limit bolt, and the vertical rod is released from the limit. Then, due to the effect of gravity, the display screen presses the vertical rod downward to slide in the cylinder until the speaker touches the ground. At this time, the present invention can be folded up. At the same time, when the speaker is against the ground, its own weight can lower the center of gravity of the present invention, thereby avoiding the probability of collapse. Then the limit bolt is screwed into the fixing frame and inserted into the screw hole B to limit the position. When it needs to be restored for use, the maintenance personnel only need to unscrew the limit bolt again, and then push the display screen upward to display the The display screen can then drive the vertical rod to slide in the cylinder until the display screen is lifted and reset, and then the limiting bolt is screwed into the fixing frame again and inserted into the screw hole A to limit the position. In the present invention, when encountering severe weather such as typhoons, the overall height and center of gravity can be lowered by adjusting the structure, thereby reducing wind resistance, reducing the risk of the device being blown down by the wind, and improving the stability and safety of the device. At the same time, the present invention allows the height of the display screen and the vertical rod to be adjusted through simple mechanical operations, which not only facilitates maintenance personnel to quickly put away the equipment in severe weather, but also can quickly reset it, reducing operational complexity and improving maintenance efficiency. When the speaker is against the ground, the center of gravity of the device is automatically adjusted due to its own weight, further reducing the risk of collapse of the equipment and enhancing the stability of the device, especially in severe weather or when the ground is unstable, it is highly practical.

[0021] The highway road condition monitoring and early warning device described in the present invention can be inserted into the ground when the sound is against the ground during actual use, so that the grip of the present invention can be improved, so that the probability of collapse can be further reduced in bad weather. At the same time, if the pile needs to be cleaned or replaced, the staff only needs to pull the pull block outward, and the pull block can then drive the round block to leave the bottom groove, and the pile can be removed at this time. When the pile needs to be installed, it is only necessary to put the round block into the bottom groove. At this time, the magnet can absorb the round block due to the effect of magnetic force, and the round block can be fixed at this time, so as to install the pile. In the present invention, when the sound is against the ground, the pile can be inserted into the ground, thereby enhancing the contact and grip of the device with the ground, especially on the platform In severe weather such as strong winds, the risk of equipment collapse can be significantly reduced, and the overall stability and wind resistance can be improved. The design of the piles makes the cleaning or replacement process very simple. Maintenance personnel only need to simply pull the pull block to quickly remove or install the piles, avoiding the use of complicated tools and tedious disassembly and assembly processes, and improving the efficiency of daily maintenance. At the same time, the design of the magnet adsorption round block can quickly and reliably fix the piles, reducing misoperation or unstable factors during the installation process. The piles are deeply embedded in the ground to form fixed points, preventing the equipment from moving or tilting under strong winds or external forces, further ensuring the working stability of the equipment, especially in continuous severe weather conditions, to ensure that the equipment can continue to play a role effectively.

[0022] The highway road condition monitoring and early warning device described in the present invention is arranged at an intersection. The staff only needs to pull the pull plate outward, and the pull plate can then drive the insertion rod to leave the socket A, and then rotate the wide-angle mirror ninety degrees, at which time the wide-angle mirror can be exposed from the side of the display screen, and then release the pull plate. Then, due to the tension of the tension spring, the tension spring pulls the pull plate to move, and the pull plate can then drive the insertion rod to be inserted into the socket B, at which time the wide-angle mirror can be limited. At this time, the driver's field of vision can be improved by the wide-angle mirror, thereby improving safety. The present invention can significantly increase the driver's field of vision at the intersection by arranging the wide-angle mirror and making it exposed from the side of the display screen when needed, so as to help the driver observe the blind spot and improve driving safety. Safety, especially in complex intersections or environments with limited vision, can more effectively avoid traffic accidents, and the setting and adjustment of the wide-angle mirror can be achieved through simple mechanical operations. The staff only needs to pull the pull plate and turn the wide-angle mirror. No complicated tools or a lot of time are required to complete the adjustment and limitation of the wide-angle mirror. It is convenient and fast, and improves the operating efficiency. The application of wide-angle mirror effectively reduces the blind spots of vision at intersections, especially for large vehicles or high-speed vehicles, providing a wider range of road conditions information to help drivers make timely judgments and avoid emergencies. At the same time, the wide-angle mirror can be easily folded up when not in use, which can facilitate the mechanical passage of large vehicles, improve road passability, and is highly practical.

It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] Embodiment 1

[0033] like Figures 1 to 7As shown, a highway road condition monitoring and early warning device according to an embodiment of the present invention includes a base 1, and the top surface of the base 1 is provided with mounting holes 14, and the mounting holes 14 are evenly distributed at the four corners of the top surface of the base 1. The mounting holes 14 can be bolted to ensure the fastening connection between the base 1 and the ground or other infrastructure, thereby increasing the stability and durability of the overall device. The material of the base 1 can be selected from high-strength alloy steel or cast iron, which can provide good load-bearing capacity and corrosion resistance, and adapt to the complex environmental conditions of highways.

[0034] The top surface of the base 1 is fixedly mounted with a cylinder 2, and the material of the cylinder 2 can be aluminum alloy or stainless steel. Stainless steel has good corrosion resistance, while aluminum alloy has the advantages of light weight and strong durability. The top of the cylinder 2 is penetrated by a vertical rod 3, and the vertical rod 3 is slidably connected with the cylinder 2. The sliding connection can be achieved by a guide rail or a built-in bearing to ensure that the vertical rod 3 slides smoothly and unimpeded in the cylinder 2, reduce the friction caused by wear, and increase the service life of the equipment. A display screen 4 is fixedly mounted on one end of the vertical rod 3. The material of the display screen 4 can be selected from tempered glass or high-strength polycarbonate to ensure its impact resistance and durability under outdoor conditions.

The material of the rain shield 5 is recommended to be a UV-resistant PC board or aluminum alloy board, which can effectively resist wind and rain in the outdoor environment and extend the service life of the equipment. A camera 6 is fixedly mounted on the top surface of the rain shield 5. The camera 6 can be fixed by a thread or a flange to ensure that it can still maintain a stable monitoring function in bad weather. The camera 6 is used to monitor the road condition information of the highway in real time. When the camera 6 detects that a vehicle is about to pass, a striking warning message will be displayed on the display screen 4. At the same time, the speaker 9 will emit a clear alarm sound to remind passing vehicles to pay attention to driving safety.

[0035] A horizontal plate 7 is fixedly installed on the surface of the vertical bar 3.

A fixing frame 10 is fixedly installed on the side of the horizontal plate 7. The material of the fixing frame 10 can be selected from corrosion-resistant stainless steel or high-strength plastic, which has good corrosion resistance and mechanical strength. The fixing frame 10 is an "L"-shaped structure that can provide stable support for the vertical bar 3. A limiting bolt 11 is inserted into the side of the fixing frame 10. The limiting bolt 11 has the same size as the screw hole A12 and the screw hole B13. The limiting bolt 11 can be threaded or snap-fitted to ensure that it can be reliably fixed when adjusting the height of the vertical rod 3. When in use, the limiting bolt 11 is screwed into the screw hole A12 or the screw hole B13 in the fixing frame 10 to achieve the limiting fixation of the vertical rod 3, ensuring the stability of the device at different heights.

[0036] Embodiment 2

A plug-in pile 18 is fixedly installed on the bottom surface of the round block 17, and the bottom end of the plug-in pile 18 is a conical structure. The plug-in pile 18 is arranged in a circular shape on the bottom surface of the round block 17. The plug-in pile 18 can be inserted into the ground when the speaker 9 is against the ground, thereby enhancing the grip of the device and improving the stability of the device under adverse weather conditions.

[0038] Embodiment 3

[0039] like Figure 6 to Figure 7As shown, in contrast to Example 1, another embodiment of the present invention is as follows: an auxiliary mechanism is provided on the back of the display screen 4, and the auxiliary mechanism includes a short rod 20, which can be rotatably connected to the display screen 4 through a bearing or a rotating shaft to ensure that it can rotate smoothly when adjusting the wide-angle lens 27.

[0040] How it works

[0041] When the camera 6 detects that a vehicle is about to pass, a striking warning message is displayed on the display screen 4. At the same time, the speaker 9 emits a clear alarm sound to remind passing vehicles to pay attention. At the same time, when encountering bad weather such as typhoons, the maintenance personnel can unscrew the limit bolt 11, and the vertical rod 3 is released from the limit. Then, due to the effect of gravity, the display screen 4 presses the vertical rod 3 downward to slide in the cylinder 2 until the speaker 9 touches the ground. At this time, the present invention can be folded up. At the same time, when the speaker 9 is against the ground, it has its own weight and can lower the center of gravity of the present invention, thereby avoiding the probability of collapse. Then the limit bolt 11 is screwed into the fixing frame 10 and inserted into the screw hole B13 to limit the position. When it needs to be restored for use, the maintenance personnel only need to unscrew the limit bolt 11 again. , and then push the display screen 4 upward, the display screen 4 can then drive the vertical rod 3 to slide in the cylinder 2 until the display screen 4 is lifted and reset, and then the limiting bolt 11 is screwed into the fixing frame 10 again and inserted into the screw hole A12 to limit the position. In the present invention, when encountering severe weather such as typhoons, the overall height and center of gravity can be lowered by adjusting the structure, thereby reducing wind resistance, reducing the risk of the device being blown down by the wind, and improving the stability and safety of the device. At the same time, the present invention allows the height of the display screen 4 and the vertical rod 3 to be adjusted through simple mechanical operations, which not only facilitates maintenance personnel to quickly put away the equipment in severe weather, but also quickly resets it, reduces the complexity of operation, and improves maintenance efficiency. When the speaker 9 is against the ground, the center of gravity of the device is automatically adjusted due to its own weight, further The risk of collapse of the equipment is reduced and the stability of the device is enhanced, especially in bad weather or when the ground is unstable. When the speaker 9 is against the ground, the stakes 18 set at this time can be inserted into the ground, which can improve the grip of the present invention. In this way, the probability of collapse can be further reduced in bad weather. At the same time, if the stakes 18 need to be cleaned or replaced, the staff only needs to pull the pull block 19 outward, and the pull block 19 can then drive the round block 17 to leave the bottom groove 15. At this time, the stake 18 can be removed. When the stake 18 needs to be installed, it is only necessary to put the round block 17 into the bottom groove 15. At this time, the magnet 16 can absorb the round block 17 due to the effect of magnetic force, and the round block 17 can be fixed at this time, so as to install the stake 18. In the present invention, when the speaker 9 When against the ground, the plug pile 18 can be inserted into the ground, thereby enhancing the contact and grip of the device with the ground, especially in severe weather such as typhoons, it can significantly reduce the risk of equipment collapse and improve the overall stability and wind resistance. The design of the plug pile 18 makes the cleaning or replacement process very simple. The maintenance personnel only need to simply pull the pull block 19 to quickly remove or install the plug pile 18, avoiding the use of complicated tools and cumbersome disassembly and assembly processes, and improving the efficiency of daily maintenance and maintenance. At the same time, the design of the magnet 16 adsorbing the round block 17 can quickly and reliably fix the plug pile 18, reducing misoperation or unstable factors during the installation process. The plug pile 18 is deeply embedded in the ground to form a fixed point to prevent the movement or tilt of the equipment under strong winds or external forces.The working stability of the equipment is further guaranteed, especially in continuous bad weather conditions, it can ensure that the equipment can continue to work effectively. When the present invention is set at an intersection, the staff only needs to pull the pull plate 23 outward, and the pull plate 23 can then drive the plug 22 to leave the socket A25, and then rotate the wide-angle mirror 27 ninety degrees, at which time the wide-angle mirror 27 can be exposed from the side of the display screen 4, and then release the pull plate 23. Then due to the tension of the tension spring 24, the tension spring 24 pulls the pull plate 23 to move, and the pull plate 23 can then drive the plug 22 to insert into the socket B26, at which time the wide-angle mirror 27 can be limited. At this time, the wide-angle mirror 27 can increase the driver's field of view, thereby improving safety. The present invention can significantly increase the wide-angle mirror 27 by arranging it and making it appear from the side of the display screen 4 when needed. The driver's field of vision at the intersection helps the driver observe the blind spot and improve driving safety, especially in complex intersections or environments with limited vision, which can more effectively avoid traffic accidents. The setting and adjustment of the wide-angle mirror 27 can be achieved through simple mechanical operations. The staff only needs to pull the pull plate 23 and turn the wide-angle mirror 27. Without complicated tools or a lot of time, the adjustment and limit of the wide-angle mirror 27 can be completed. It is convenient and fast, and the operation efficiency is improved. The application of the wide-angle mirror 27 effectively reduces the blind spot of the intersection, especially for large vehicles or high-speed vehicles, providing a wider road condition information, helping the driver to make judgments in time and avoid emergencies. At the same time, the wide-angle mirror 27 can be easily folded when not in use, which can facilitate the mechanical passage of large vehicles and improve road passability.
