[0024] See also Figure 1-Figure 6A road visibility detection and warning device includes a detection and warning mechanism 1, the detection and warning mechanism 1 includes a mounting shell 101, a rotating mechanism 2 is connected to the bottom of the mounting shell 101, and a lifting mechanism 3 is connected to one side of the rotating mechanism 2:

[0025] Furthermore, the rotating mechanism 2 includes a mounting base 201 arranged below the mounting shell 101, a fixed plate 202 is fixedly connected inside the mounting base 201, a rotating shaft 203 is rotatably connected to the center of the fixed plate 202, the top of the rotating shaft 203 extends to the top of the mounting base 201 and is fixedly connected to the bottom of the mounting shell 101, the bottom of the rotating shaft 203 extends to the bottom of the mounting base 201 and is fixedly connected to a first motor 204, and the first motor 204 is fixedly arranged at the bottom of the mounting base 201.

[0026] This is achieved through the fixed plate 202 in the mounting base 201 and the central rotating shaft 203. The first motor 204 drives the rotating shaft 203 to rotate, thereby driving the entire detection and early warning mechanism 1 to rotate around the top of the mounting shell 101. This design allows the device to adjust the facing angle according to actual needs or sunlight direction to avoid interference from direct light or make full use of natural light to ensure the accuracy of monitoring. The lifting mechanism 3 is used to change the overall height of the device. The lifting function allows the device to work at different heights to adapt to different road conditions or avoid obstacles and reduce monitoring blind spots.

[0027] The device can adapt to a variety of environments and conditions more flexibly, improve the coverage and efficiency of monitoring, and reduce monitoring errors or blind spots caused by improper fixed positions. At the same time, this design is also convenient for equipment maintenance and upgrading, because when the position needs to be adjusted or repaired, it can be operated more conveniently through the rotating mechanism 2 and the lifting mechanism 3 without complicated disassembly and assembly processes.

[0028] Furthermore, a protective cover 102 is fixedly connected to the top of the mounting shell 101, a visibility sensor 103 is fixedly connected between the mounting shell 101 and the protective cover 102, a connecting shell 104 is fixedly connected to the top of the protective cover 102, and a warning light 105 is fixedly connected to the top of the connecting shell 104.

[0029] The protective cover 102 is installed on the top of the mounting shell 101. Its main function is to protect the visibility sensor 103 from external environmental factors such as rain, dust, impact, etc., to ensure that the visibility sensor 103 can work stably and accurately for a long time. The visibility sensor 103 is located in a fixed position between the mounting shell 101 and the protective cover 102. It is the core component of the equipment and is responsible for monitoring the concentration of aerosol particles in the air or the degree of light scattering to calculate the visibility of the road. The connecting shell 104 provides an installation position for the warning light 105 to ensure the stability and directionality of the warning light 105. When the visibility is lower than the set threshold, the warning light 105 is activated by the control system to send out an obvious visual warning signal, which can directly remind passing vehicles and pedestrians to pay attention to safety, or serve as an intuitive indication for the traffic management center to take action.

[0030] Furthermore, electric push rods 106 are fixedly connected to the left and right sides of the top of the inner wall of the connecting shell 104, and the telescopic end of the electric push rod 106 is rotatably connected to a cleaning brush roller 107. The cleaning brush roller 107 is slidably connected to the protective cover 102 and fits the front side of the visibility sensor 103.

[0031] When the electric push rod 106 drives the cleaning brush roller 107 to perform telescopic movement, the cleaning brush roller 107 rolls along the surface of the visibility sensor 103, which can effectively remove accumulated dust, dirt or other obstructions, keep the lens or light-transmitting area of ​​the visibility sensor 103 clean, and ensure that the accuracy of the measurement data is not affected by external pollution.

[0032] Furthermore, a ratchet 205 is fixedly sleeved on the surface of the rotating shaft 203 , a pawl 206 is clamped on the surface of the ratchet 205 , and the pawl 206 is rotatably arranged on the top of the fixing plate 202 .

[0033] The ratchet 205-pawl 206 structure allows the device to drive the pawl 206 into the corresponding groove of the ratchet 205 through the first motor 204 after the desired angle is adjusted, thereby fixing the rotation position and preventing the angle from changing due to external forces such as wind or misoperation. At the same time, this also facilitates precise control of the rotation angle when maintaining or adjusting the device, ensuring the stability and repeatability of the device positioning.

[0034] Furthermore, a positioning block 208 is fixedly connected to the top of the fixing plate 202 , and a spring 207 is fixedly connected between the positioning block 208 and the pawl 206 .

[0035] Spring 207 not only simplifies the positioning and locking operation of pawl 206, improves the convenience and response speed of operation, but also adds flexibility and durability to the entire locking mechanism. The buffering effect of spring 207 can also absorb a certain amount of external force impact, protect the ratchet 205 and pawl 206 from damage, and extend the service life of the equipment.

[0036] Furthermore, a connecting frame 209 is fixedly connected to one side of the mounting seat 201 , a connecting plate 210 is fixedly connected to one side of the connecting frame 209 , and a lifting mechanism 3 is fixedly connected to one side of the connecting plate 210 .

[0037] The connecting plate 210 is fixed to one side of the connecting frame 209. It serves as a platform directly connected to the lifting mechanism 3, further strengthening the mechanical connection between the lifting mechanism 3 and other parts of the equipment, ensuring the smoothness and safety of the lifting action.

[0038] Furthermore, the lifting mechanism 3 includes a lifting seat 301, a threaded rod 302 is rotatably connected inside the lifting seat 301, a second motor 303 is fixedly connected to the top of the threaded rod 302, the second motor 303 is fixedly arranged on the top of the lifting seat 301, a threaded block 304 is threadedly connected to the surface of the second motor 303, and one side of the threaded block 304 is fixedly connected to one side of the connecting plate 210.

[0039] The top of the threaded rod 302 is connected to the second motor 303, and the rotation of the second motor 303 directly drives the threaded rod 302 to rotate, thereby controlling the up and down movement of the threaded block 304 to achieve the lifting of the device.

[0040] Furthermore, the inner wall of the threaded block 304 is slidably connected to a limit rod 305 , which is fixedly arranged inside the lifting seat 301 . The left and right sides of the lifting seat 301 are fixedly connected to positioning plates 306 , on which positioning bolts 307 are threadedly connected.

[0041] The limit rod 305 is set on the inner wall of the threaded block 304 and is slidably connected to the inside of the lifting seat 301 to limit the movement range of the threaded block 304 to prevent damage to the equipment due to excessive rising or falling, and ensure safe operation. The positioning plate 306 is installed on the left and right sides of the lifting seat 301. The threaded positioning bolts 307 can adjust and fix the position of the lifting mechanism 3 at a specific height to ensure that the equipment works stably at the required height and prevent accidental sliding.

[0042] The lifting mechanism 3 is driven by a screw thread to achieve precise lifting of the device, and the safety of the lifting process and the precise controllability of the position are ensured through the limit rod 305, the positioning plate 306, the positioning bolt 307 and other components. Such a lifting mechanism 3 design not only meets the flexibility of height adjustment, but also ensures the stability and safety of the equipment operation, which is an important mechanical innovation in road visibility detection and early warning equipment.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
