Description

Technical Field

[0001] This utility model belongs to the field of road sign technology and relates to a lightweight, high-strength, windproof road sign. Background Technology

[0002] Road traffic signs are crucial facilities for ensuring road traffic safety and guiding smooth vehicle flow. In areas prone to strong winds, such as highways, Gobi Desert, deserts, and coastal regions, traditional road signs face severe challenges. Currently, common road signs are mainly made of aluminum alloy or steel plates and fixedly installed on steel posts. While this type of structure possesses a certain degree of rigidity, it has revealed numerous defects and shortcomings in long-term use: First, regarding structural strength and durability, metal signboards and posts are heavy, making transportation and installation inconvenient and requiring high-quality foundation construction. Under long-term exposure to alternating strong wind loads, metal structures, especially welds or joints, are prone to metal fatigue, leading to cracking, deformation, and even collapse. This not only shortens the lifespan of the signs but also poses significant traffic safety hazards. Furthermore, in windy and sandy environments, metal surfaces are easily corroded and eroded, affecting appearance and reducing structural strength, resulting in high maintenance and replacement costs. Second, in terms of functionality, most existing road signs are passive and static, with limited functionality. They cannot sense changes in the external environment, especially in response to sudden increases in crosswinds and other dangerous weather conditions. Drivers cannot obtain real-time risk warnings from the signs and can only react passively when encountering strong winds, increasing the risk of driving in inclement weather. Third, regarding energy supply, some signs are attempting to use external power or solar power to achieve active illumination or simple warning functions. However, external power supply is difficult to achieve in remote areas without power grids; and traditional solar power systems can usually only provide energy for nighttime lighting, with limited power and energy storage, making it difficult to support high-power functions such as continuous wind speed monitoring, data processing, and active early warning display under strong light. They are also prone to failure in continuous rainy weather, resulting in insufficient system reliability.

[0003] Therefore, there is an urgent need in this field for a marker that can overcome the above-mentioned defects and has both lightweight and high-strength structure to meet the road traffic safety requirements of areas with harsh environments such as strong winds. Utility Model Content

[0004] The purpose of this utility model is to provide a lightweight, high-strength, windproof road sign to solve the technical problems of poor wind resistance and short service life of existing road signs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a lightweight, high-strength, windproof road sign, including a signboard; a solar panel and an indicator light are installed on the top of the signboard, and the solar panel and the indicator light are electrically connected; a support rod is connected to the bottom of the signboard; the support rod includes a metal core and a lightweight sleeve fitted over the metal core.

[0006] Furthermore, the signboard includes a carbon fiber reinforced composite board, the surface of which is covered with a reflective film.

[0007] Furthermore, a glass fiber interlayer is provided between the carbon fiber composite plate and the reflective film.

[0008] Furthermore, a honeycomb aluminum core material is filled between the glass fiber sandwich layer and the carbon fiber reinforced composite plate.

[0009] Furthermore, a foam core material is filled between the glass fiber sandwich layer and the carbon fiber reinforced composite board.

[0010] Furthermore, a wind speed monitoring device is also installed on the top of the sign; the wind speed monitoring device is electrically connected to the solar panel; the wind speed monitoring device is used to monitor the ambient wind speed.

[0011] Furthermore, the wind speed monitoring device is an ultrasonic wind speed sensor.

[0012] Furthermore, a wind power generation device is also installed on the top of the sign; the wind power generation device and the indicator light are electrically connected.

[0013] Furthermore, the lightweight sleeve is a carbon fiber sleeve.

[0014] Furthermore, a damping and shock absorption device or a buffer sleeve is provided at the bottom of the support rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a lightweight, high-strength, windproof road sign. The support rod at the bottom of the sign adopts a structure with a metal core and a lightweight sleeve covering the metal core. The metal core provides strong core support for the support rod, ensuring that the sign remains stable under various harsh weather conditions, especially in strong winds, and is not easily tilted or damaged. The lightweight sleeve effectively reduces the weight of the support rod while maintaining the overall structural strength, lowering material and transportation costs, and facilitating installation and maintenance. The solar panel installed on the top of the sign can fully absorb solar energy and convert it into electrical energy to power the indicator lights connected to it, providing warnings to drivers in extreme environments or special situations.

[0016] Furthermore, this utility model sign uses a fiberglass sandwich panel, a honeycomb aluminum core, and a carbon fiber reinforced composite panel to achieve both lightweight and high rigidity. The surface is covered with a UV-resistant and sand-erosion-resistant reflective film to ensure long-term visibility under strong winds, sandstorms, and intense sunlight.

[0017] Furthermore, the support rod of this invention adopts a composite structure of carbon fiber sleeve + metal core, which ensures bending strength while significantly reducing overall weight. A damping and shock absorption device or buffer sleeve is installed at the bottom of the support rod to alleviate the impact load of instantaneous strong winds and prevent foundation cracking.

[0025] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings: See Figure 1This utility model discloses a lightweight, high-strength, windproof road sign, including a signboard 6. A solar panel 1 and an indicator light 3 are installed on the top of the signboard 6, and the solar panel 1 and indicator light 3 are electrically connected. A support rod 5 is connected to the bottom of the signboard 6. The support rod 5 includes a metal core and a lightweight sleeve fitted over the metal core. In this embodiment, the support rod 5 at the bottom of the signboard 6 adopts a structure of a metal core and a lightweight sleeve fitted over the metal core. The metal core provides strong core support for the support rod 5, ensuring that the signboard 6 remains stable under various harsh weather conditions, especially in strong winds, and is not easily tilted or damaged. The lightweight sleeve, while ensuring the overall structural strength, effectively reduces the weight of the support rod, lowers material and transportation costs, and facilitates installation and maintenance. The solar panel installed on the top of the signboard can fully absorb solar energy and convert it into electrical energy to power the indicator light connected to it, providing warnings to drivers in extreme environments or special situations.

[0028] In one feasible embodiment of this utility model, see [link to relevant documentation]. Figure 2 The sign 6 comprises a carbon fiber reinforced composite board 10, the surface of which is covered with a reflective film 7. A fiberglass interlayer 8 is also disposed between the carbon fiber reinforced composite board 10 and the reflective film 7. A honeycomb aluminum core material 9 or a foam core material is filled between the fiberglass interlayer 8 and the carbon fiber reinforced composite board 10. In this embodiment, both the honeycomb aluminum core material 9 and the foam core material are lightweight, significantly reducing the overall weight of the sign and achieving the goal of lightweighting. Furthermore, they also possess certain buffering and energy absorption functions; when the sign 6 is subjected to external impact, they can effectively absorb energy, reduce damage, and ensure the rigidity of the sign 6. This allows the sign 6 to maintain high rigidity while being lightweight, enabling it to adapt to various complex road environments. In addition, the surface is covered with a UV-resistant and sand-erosion-resistant reflective film, ensuring long-term visibility under strong winds, sandstorms, and strong sunlight conditions.

[0029] In one feasible embodiment of this utility model, a wind speed monitoring device 4 is also installed on the top of the sign 6; the wind speed monitoring device 4 is electrically connected to the solar panel 1; the wind speed monitoring device 4 is used to monitor the ambient wind speed. The wind speed monitoring device 4 preferably uses an ultrasonic wind speed sensor to collect wind speed data in real time. When the wind speed reaches a warning threshold (e.g., 12–15 m / s), an indicator light 3 is illuminated. The indicator light 3 preferably uses an LED light, which triggers flashing or a buzzer when the wind speed reaches a danger threshold (e.g., 20–25 m / s). Ultrasonic wind speed sensors have many advantages: they have high measurement accuracy, accurately capturing minute changes in wind speed; they have a fast response speed, providing real-time feedback of wind speed data; and their robust structure and strong anti-interference capabilities allow them to work stably under various harsh weather conditions, providing accurate and reliable wind speed information for the safe operation of road traffic.

[0030] In one feasible embodiment of this utility model, a wind power generation device 2 is also installed on the top of the sign 6; the wind power generation device 2 and the indicator light 3 are electrically connected. The solar panel 1 is equipped with a lithium battery as an energy storage unit, which, together with the wind power generation device 2, realizes a hybrid power supply of solar and wind power. In sunny weather, the solar panel 1 plays a major role in efficiently collecting solar energy; when encountering cloudy or rainy weather, and solar energy collection is limited, the wind power generation device 2 uses wind power to continuously generate electricity. The two complement each other, jointly ensuring the continuous and stable operation of the sign 6 under various weather conditions. This innovative power supply method completely eliminates the dependence on external power supply, greatly reducing construction and maintenance costs. It is especially suitable for remote highways, deserts, Gobi, and other uninhabited areas, where traditional power grids are difficult to lay and costly. However, the sign 6 of this utility model, with its self-sufficient energy supply system, can work stably for a long time, providing clear and accurate directional information for passing vehicles and pedestrians, effectively improving the safety and convenience of road traffic.

[0031] In one feasible embodiment of this utility model, the lightweight sleeve is a carbon fiber sleeve. The structure of the carbon fiber sleeve + metal core reduces the overall weight of the sign by 30%–50%, making transportation and installation more convenient. The metal core provides a solid and reliable core support for the entire support rod, ensuring that the sign 6 remains stable and is not easily deformed or damaged when facing external forces such as strong winds and vehicle collisions. The carbon fiber sleeve, due to its lightweight characteristics, significantly reduces the weight of the support rod without affecting the overall structural strength. The high-strength structure improves wind resistance, effectively resisting the 12–13 level strong winds commonly found in high-wind areas, and extending its service life. A damping shock absorption device or buffer sleeve is provided at the bottom of the support rod 5.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
