Description

Technical Field

[0001] The present invention relates to the field of road construction, in particular to a highway construction warning device for use in harsh environments. Background Art

[0002] As for current highway construction, some road conditions are relatively harsh. After the traditional highway warning device is installed, the reflective coating on the surface will be blocked by a large amount of dust, and the reflective effect of the headlights will drop sharply at night, the overall visual distance will be shortened, and the safety hazards will increase. In order to solve this problem, self-luminous highway warning methods are currently used. However, in some harsh environments, construction parties mostly use generators. If they continue to provide electricity when not in construction, the energy consumption is relatively high. If batteries are used, the operation requires charging, which is relatively cumbersome and inconvenient for long-term construction. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that traditional highway warning devices have poor adaptability to harsh environments and to propose a highway construction warning device for harsh environments.

[0004] To achieve the above-mentioned object, the present invention adopts the following technical solution: a road construction warning device for use in harsh environments, comprising a base, a vertical cylinder fixed to the upper surface of the base, a focusing shield fixed above the vertical cylinder, and a diffuser shield connected to one side of the focusing shield;

[0005] A refracting mirror for primary light redirection is fixed to the inner wall of the base. A lens module for focusing light to enhance brightness is provided on one side of the refracting mirror. A warning mirror for secondary light redirection is provided above the lens module. A warning sign for affixing a warning sign is fixed to the inner wall of the diffuser.

[0006] A self-positioning flashing device is installed on the top of the condenser, and the warning mirror is installed at the bottom of the self-positioning flashing device after being trimmed.

[0007] As a further description of the above technical solution: the incident angles of the refracting mirror and the warning mirror are both 45°.

[0008] As a further description of the above technical solution: the inner wall of the diffuser is arranged in an inclined shape, and the inclination is adapted to the refraction angle of the warning mirror.

[0009] As a further description of the above technical solution: the lens module includes a convex lens for focusing light, a buffer ring is fitted on the surface of the convex lens, a mounting ring is fitted and fixed on the surface of the buffer ring, and the mounting ring is fitted and fixed on the inner wall of the vertical tube.

[0010] As a further description of the above technical solution: the self-positioning flashing device includes a balancing shaft that passes through and rotates on the top of the condenser, the bottom end of the balancing shaft is fixed to the warning mirror, the top end of the balancing shaft is installed with a universal joint and is coupled with a positioning shaft through the universal joint transmission, the surface of the positioning shaft is installed with a retaining frame that supports it, the retaining frame is fixed to the surface of the diffuser, the top end of the positioning shaft is fixed with a positioning counterweight, and the surface of the balancing shaft is fixed with a fan blade.

[0011] As a further description of the above technical solution: a column is fixed to the lower surface of the base, a bottom plate is fixed to the bottom end of the column, and a plurality of reinforcement anchor holes are opened on the surface of the bottom plate.

[0012] As a further description of the above technical solution: two support plates are symmetrically fixed to the surface of the base, and trusses for fitting the base support are fixed to the opposite surfaces of the two support plates.

[0013] As a further description of the above technical solution: a sealing seat is installed through the surface of the support plate, and a lamp rod is commonly provided on the opposite surfaces of the two sealing seats, and the lamp rod is located in the base.

[0014] As a further description of the above technical solution: the inner walls of the condenser and the diffuser are both provided with a reflective coating, and the inner wall of the condenser is arranged in an arc shape.

[0015] As a further description of the above technical solution: a light-transmitting plate is provided on one side of the base, and the light-transmitting plate is inclined at an angle of 5-15 degrees.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] This solution captures light from oncoming headlights and changes its direction under the action of a refracting mirror. When the light passes through the lens module, the wide range of light from the refracting mirror is focused and irradiated onto the surface of the warning mirror. Since the lens module does not have a light correction lens, the light is focused and tilted and irradiates the surface of the warning mirror. The tilted light forms a diffuse light based on the principle that the greater the incident angle of the mirror, the greater the reflection angle, and the smaller the incident angle, the smaller the reflection angle. After focusing, the refracted light is transformed into diffuse light and evenly irradiates one side of the warning sign. At this time, the reflective sticker sign attached to the surface of the warning sign can emit light. This method can use the self-luminous light of the vehicle to warn, effectively avoiding the problem of limited warning effect of traditional reflective coatings after being obscured by dust.

[0018] At the same time, some severe weather conditions are often accompanied by strong winds. When the wind is strong, the wind blades rotate with the balance shaft, and the balance shaft rotates with the warning mirror. The warning mirror illuminates the spotlight through the reflective coating inside the spotlight, causing the warning sign to flash brightly and darkly in the alternating changes of direct and reflected light, which can increase the warning degree during the flashing.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] like Figure 1-Figure 5 As shown, the present invention provides: a road construction warning device for harsh environments, comprising a base 1, a vertical cylinder 2 is fixed on the upper surface of the base 1, and a focusing cover 3 is fixed above the vertical cylinder 2, and a diffuser cover 4 is provided on one side of the focusing cover 3;

[0028] A folding mirror 8 for primary light redirection is fixed to the inner wall of the base 1. A lens module 5 for focusing light to enhance brightness is provided on one side of the folding mirror 8. A warning mirror 7 for secondary light redirection is provided above the lens module 5. A warning sign 11 for affixing a warning sign is fixed to the inner wall of the diffuser 4.

[0029] A self-positioning flashing device 6 is installed on the top of the condenser 3, and a warning mirror 7 is installed on the bottom end of the self-positioning flashing device 6 after being balanced.

[0030] This solution captures light from oncoming headlights, redirects it once using a folding mirror 8, focuses it through a lens module 5 to enhance its brightness, and then redirects it again through a warning mirror 7. This diffused light evenly illuminates the surface of the warning sign 11, creating an automatic luminous warning system in conjunction with a reflective sticker. This avoids the problem of traditional devices with reduced warning effectiveness due to dust obscuring the reflective coating. Furthermore, the device incorporates a wind-driven balance shaft 65 and a rotating mechanism within the warning mirror 7, allowing the warning sign 11 to flicker in response to wind fluctuations, enhancing warning effectiveness. Even at low wind speeds, it exhibits subtle brightness changes, ensuring a continuous warning effect in inclement weather. Furthermore, the reflective coating on the inner surfaces of the focusing hood 3 and the diffuser hood 4 further improves light utilization efficiency, avoids light waste, and ensures the device maintains high brightness. In foggy conditions, the light stick 10 is activated to enhance light penetration, effectively improving visibility in complex environments and providing a more reliable highway construction warning function.

[0031] Specifically, such as Figure 5 As shown: the incident angles of the refracting mirror 8 and the warning mirror 7 are both 45°.

[0032] The angle of incidence for both the folding mirror 8 and the warning mirror 7 is set at 45°. This design takes advantage of the fact that light incident at a 45° angle can achieve the most precise change of direction. At this angle, the folding mirror 8 refracts the light once, directing the previously dispersed light in a predetermined direction, thus facilitating subsequent focusing. The warning mirror 7, similarly designed with a 45° angle of incidence, refracts the focused light back onto the warning sign 11, creating a uniform diffusion effect and ensuring the brightness and visual stability of the warning sign.

[0033] The advantage of this structure is that it can optimize the light path without adding complex optical design, while ensuring maximum light energy utilization. In addition, the 45° angle design can also reduce the loss of light during multiple reflections during the propagation of light on the mirror surface, making the overall light path more efficient and providing more stable warning performance for the device.

[0034] A light-transmitting plate 9 is provided on one side of the base 1, and the light-transmitting plate 9 is tilted at an angle of 5-15 degrees, wherein the light-transmitting plate 9 can keep the light passing through, and at the same time the whole is tilted at an angle of 5-15 degrees so that its surface faces downward and dust is not easily deposited.

[0035] Specifically, such as Figure 1 As shown, the inner wall of the diffuser 4 is arranged in an inclined shape, and the inclination is adapted to the refraction angle of the warning mirror 7.

[0036] The inner wall of the diffuser 4 is inclined, its slope matching the angle of light refraction by the warning mirror 7. This design more efficiently guides the light refracted by the warning mirror 7, achieving further uniform light diffusion. Through the rational design of the inclined inner wall, the multiple refractions and reflections of light on the inner wall of the diffuser 4 are prevented from excessive concentration or ineffective scattering, thereby maximizing light utilization efficiency and ensuring uniform light illumination across all areas of the warning sign 11.

[0037] The advantage of this structure is that the tilted arrangement of diffuser 4 precisely matches the optical properties of warning mirror 7, allowing for more even light diffusion and improved brightness consistency across warning sign 11, preventing areas of excessive brightness or darkness, thereby enhancing the warning effect. The tilted design of diffuser 4 also mitigates the direct impact of external environmental factors, such as dust or rain, on the inner wall, further enhancing the reliability and applicability of the device, ensuring it maintains effective warning performance even in harsh environments.

[0038] Specifically, such as Figure 4 As shown, the lens module 5 includes a convex lens 53 for focusing light, a buffer ring 52 is provided on the surface of the convex lens 53, and a mounting ring 51 is provided on the surface of the buffer ring 52. The mounting ring 51 is fixed to the inner wall of the vertical tube 2.

[0039] The convex lens 53 in the lens module 5 is used to focus light. Its design can narrow the wide range of light from the refraction mirror 8 into a smaller area, thereby increasing the brightness and energy density of the light and ensuring that the light has sufficient intensity to achieve effective secondary refraction when passing through the warning mirror 7. The buffer ring 52 attached to the surface of the convex lens 53 plays an important protective and cushioning role in the structure, effectively absorbing external vibrations or shocks, and preventing the convex lens 53 from being damaged by drastic environmental changes or during use. The buffer ring 52 also serves as an auxiliary fixing function, ensuring that the convex lens 53 maintains a stable optical center during use.

[0040] The mounting ring 51 is arranged on the surface of the buffer ring 52, which is fitted and fixed on the inner wall of the vertical tube 2. They cooperate with each other to provide a stable mounting support. Taking into account the working stability and durability of the optical components in actual applications, it can not only ensure the accuracy of light focusing, but also enhance the seismic resistance and reliability of the device in complex construction environments, thereby improving the performance and life of the overall warning device.

[0041] Specifically, such as Figure 3 As shown: the self-positioning flashing device 6 includes a balancing shaft 65 that rotates through the top of the condenser 3, the bottom end of the balancing shaft 65 is fixed to the warning mirror 7, the top end of the balancing shaft 65 is installed with a universal joint 64 and is coupled with a positioning shaft 62 through the universal joint 64, the surface of the positioning shaft 62 is installed with a retaining frame 61 that supports it, the retaining frame 61 is fixed to the surface of the diffuser 4, the top end of the positioning shaft 62 is fixed with a positioning counterweight 63, and the surface of the balancing shaft 65 is fixed with a fan blade 66.

[0042] The self-positioning flashing device 6 uses a balancing shaft 65 that rotates through the top of the condenser 3 as its core component to achieve a dynamic flashing effect. The bottom end of the balancing shaft 65 is fixed to the warning mirror 7, allowing the warning mirror 7 to change the direction of light reflection as the balancing shaft 65 rotates. This produces a flickering effect when light hits the warning sign 11, significantly improving the visibility and warning effect of the warning sign.

[0043] A universal joint 64 is installed at the top of the balancing shaft 65, which is in transmission cooperation with the positioning shaft 62, so that the positioning shaft 62 can flexibly adjust its direction, ensuring that the warning mirror 7 can be quickly reset to the optimal position after moving under the action of wind or other external forces.

[0044] A retaining bracket 61 is mounted on the surface of the positioning shaft 62, which is fixed to the surface of the diffuser 4. This provides stable support for the positioning shaft 62 and prevents it from shifting due to vibration or external forces during rotation. A positioning counterweight 63 is fixed to the top of the positioning shaft 62. This center of gravity adjustment function ensures that the device automatically returns to its initial state during low wind speeds or when the wind stops, allowing the warning sign 11 to maintain a high brightness distribution. Blades 66 are also fixed to the surface of the balancing shaft 65. These blades capture the ambient wind force, driving the balancing shaft 65 to rotate, enabling the warning mirror 7 to achieve regular rotation and light adjustment.

[0045] This achieves a completely passive wind-driven system, producing a highly effective flashing warning effect without the need for additional energy. By dynamically adjusting the reflection and diffusion direction of light, the device flexibly responds to varying wind conditions, ensuring that the brightness and flashing frequency of the warning sign 11 adapt to environmental changes. This enhances the device's adaptability and reliability while reducing operating and maintenance costs. This makes it a highly efficient, energy-efficient warning system suitable for harsh environments.

[0046] Specifically, such as Figure 1 As shown, a column 12 is fixed to the lower surface of the base 1, a bottom plate 13 is fixed to the bottom end of the column 12, and a plurality of reinforcement anchor holes 17 are opened on the surface of the bottom plate 13.

[0047] A column 12 is fixed to the lower surface of the base 1. The column 12 is the main load-bearing component of the entire warning device, ensuring that the device can stand upright stably. A base plate 13 is fixed to the bottom end of the column 12. The base plate 13 provides additional stability through large-area contact with the ground. At the same time, it effectively disperses stress under the action of external forces to prevent the device from losing balance due to tilting or vibration. Several reinforced anchors 17 opened on the surface of the base plate 13 further enhance the reliability of the structure. The reinforced anchors 17 facilitate the use of anchoring devices (such as bolts or nail piles) to firmly fix the base plate 13 to the ground. Especially in harsh environmental conditions such as strong winds or ground vibrations, the wind resistance and earthquake resistance of the device can be significantly enhanced.

[0048] The advantage of this design is that it provides a reliable foundation for the device, adapting to a variety of construction environments. Whether working in soft soil, hard rock, or on slopes, the anchor system ensures the device's stability. The combination of base plate 13 and reinforced anchors 17 ensures the device's overall structure remains stable over time, effectively extending its service life while reducing the need for frequent maintenance, thereby improving the reliability and efficiency of the construction site warning device.

[0049] Specifically, such as Figure 2 As shown, two support plates 14 are symmetrically fixed to the surface of the base 1 , and trusses 15 for supporting the base 1 are fixed to the opposite surfaces of the two support plates 14 .

[0050] The support plate 14 is supported by the truss 15 and the base 1, and mainly assists the support of the column 12 to improve the overall stability.

[0051] Specifically, such as Figure 1 As shown, a sealing seat 16 is installed through the surface of the support plate 14 , and a lamp stick 10 is provided on the opposite surfaces of the two sealing seats 16 , and the lamp stick 10 is located in the base 1 .

[0052] By providing the sealing seat 16, the sealing seat 16 can keep one end of the lamp stick 10 sealed, and at the same time facilitate the removal of the lamp stick 10 for maintenance and replacement. When conditions are suitable, the lamp stick 10 can actively provide light source, thereby improving the stability of the overall operation.

[0053] Specifically, such as Figure 2 As shown, the inner walls of the condenser 3 and the diffuser 4 are both provided with a reflective coating, and the inner wall of the condenser 3 is arranged in an arc shape.

[0054] The inner walls of both the focuser 3 and the diffuser 4 are coated with a reflective coating, significantly improving light utilization efficiency. The curved inner wall of the focuser 3 helps to more efficiently focus incoming light, and the reflective coating further enhances its reflection, significantly improving light concentration and brightness. Furthermore, the reflective coating of the diffuser 4 ensures that even when the warning mirror 7 rotates, the light from the diffuser 4 continues to illuminate the warning sign 11.

[0055] This solution captures the light from the oncoming headlights and changes its direction under the action of the folding mirror 8. When the light passes through the lens module 5, the wide range of light from the folding mirror 8 is focused and irradiated on the surface of the warning mirror 7. Since the lens module 5 does not have a lens for light correction, the light is focused and tilted and irradiates the surface of the warning mirror 7. The tilted light forms a diffuse light based on the principle that the greater the incident angle of the mirror, the greater the reflection angle, and the smaller the incident angle, the smaller the reflection angle. The refracted light after focusing is converted into diffuse light and evenly irradiates one side of the warning sign 11. At this time, the reflective sticker sign attached to the surface of the warning sign 11 can emit light. This method can use the self-luminous light of the vehicle to warn, effectively avoiding the problem that the traditional reflective coating has limited warning effect after being obscured by dust.

[0056] At the same time, some severe weather conditions are often accompanied by strong winds. When the wind is strong, the blades 66 rotate with the balance shaft 65, and the balance shaft 65 rotates with the warning mirror 7. The warning mirror 7 illuminates the focus cover 3, which is then illuminated by the reflective coating inside the focus cover 3, so that the warning sign 11 flashes brightly and dimly in the alternating changes of direct light and reflected light, which can improve the warning degree during the flashing.

[0057] When the wind speed decreases, the positioning shaft 62 is tilted, so that the positioning weight 63 returns to the lowest position. At the same time, the positioning shaft 62 rotates with the balancing shaft 65 until the warning mirror 7 faces the warning sign 11. In this way, when the wind speed is low and cannot meet the fast flashing requirement, the positioning shaft 62 cannot rotate with the positioning weight 63, but it swings under the action of the wind. At this time, the warning sign 11 shows a small amplitude and rapid change in light and dark. When the wind speed increases, the fan blade 66 applies enough kinetic energy to the balancing shaft 65, so that the positioning shaft 62 rotates with the positioning weight 63. At this time, the rotation speed is fast, and the light and dark difference of the warning sign 11 is large, the flashing frequency is high, and the warning effect is good.

[0058] When the above-mentioned light flashes under the action of wind, the whole is not completely dark. For example, when the warning mirror 7 rotates to face completely away from the warning sign 11, the light shines on the inner wall of the condenser 3, and the reflective coating inside the condenser 3 disperses and refracts the light, so that the warning sign 11 still has a certain brightness, which can play a warning effect.

[0059] In foggy weather, the light stick 10 is lit to illuminate the refractive mirror 8 with high brightness, which is focused and then enhanced in brightness for warning, with better fog penetration effect. When necessary, the larger space on the surface of the light-transmitting plate 9 can also be used to paste translucent reflective stickers for warning, and directly illuminated by the light stick 10, so as to achieve warning coordination with larger signs.

[0060] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
