Description

Technical Field

[0001] This application relates to the field of shading canopy technology, and more particularly to a combined induced shading canopy for the exit of a ramp tunnel. Background Technology

[0002] As an important component of highway engineering, ramp tunnels have always been a focus of traffic safety concerns due to their driving risks. Compared with open roads, ramp tunnels are more prone to traffic accidents due to their unique semi-enclosed tubular spatial structure.

[0003] The significant environmental differences between the entrance and exit areas of ramp tunnels create both "black hole" and "white hole" effects for drivers. Furthermore, as drivers approach the tunnel exit, the sudden change in visual adaptation can lead to escape maneuvers such as acceleration or sharp turns—the escape effect. The combined effect results in a significantly higher accident rate at ramp tunnel entrances and exits compared to inside the tunnel itself. Moreover, the accident rate at tunnel exits is higher than at entrances, placing greater emphasis on the guidance effectiveness of ramp tunnel exit areas. Summary of the Invention

[0004] In order to overcome the technical problems described in the prior art, this application provides a combined induced light-shading canopy for the exit of a ramp tunnel.

[0005] The technical solution provided in this application for a combined induced light-shading canopy for ramp tunnel exits is as follows: A combined induced light-shading canopy for ramp tunnel exits, comprising: The main body of the sunshade canopy is located at the exit of the ramp tunnel. It includes sunshade canopy sidewalls on both sides of the ramp tunnel, a support frame installed between the two sunshade canopy sidewalls, and a sunshade film fixed on the support frame. The sunshade film includes a sunshade film on the outer layer and a sunshade film on the inner layer. The top visual guidance component is set on the top of the sunshade canopy body. It includes multiple sets of hollowed-out guide arrows set on the sunshade film. Each set of hollowed-out guide arrows corresponds to a multiple driving lane and is located directly above the corresponding driving lane, which can form a projection on the corresponding driving lane. A side-mounted visual guidance component, disposed on the side wall of the shade canopy, includes multiple reflective film guide arrows disposed on the side wall of the shade canopy, the multiple reflective film guide arrows being evenly distributed along the length direction of the shade canopy body; and A sound guiding component is installed on the side wall of the shade canopy, which includes multiple broadcasters installed on the side wall of the shade canopy, and the multiple broadcasters are evenly distributed along the length of the shade canopy body.

[0006] Furthermore, the main body of the sunshade canopy is arranged in a linearly gradually increasing height towards the direction away from the exit of the ramp tunnel.

[0007] Furthermore, multiple suspension cables are fixed on the support frame, and the multiple suspension cables and the support frame together form a stable spatial network structure.

[0008] Furthermore, the light-shielding film and the sun-shielding film are separated from each other, forming a ventilation channel between them.

[0009] Furthermore, a lighting system is also installed on the top of the shading canopy, located outside the shading film.

[0010] Furthermore, LED dynamic light strips distributed along the length of the side wall of the shading canopy are installed.

[0011] Furthermore, the LED dynamic light strip includes an upper light strip and a lower light strip, which are arranged parallel to each other, and the reflective film guide arrow is located between the upper light strip and the lower light strip.

[0012] Furthermore, sound-absorbing panels are installed on the side walls of the shade canopy.

[0013] Furthermore, the sunshade canopy is equipped with a maintenance access road, and a road barrier is installed on the side of the maintenance access road facing the driving lane.

[0014] Furthermore, two-color vehicle distance adjustment markings are provided at the edge of the driving lane.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. In this invention, the main body of the sunshade canopy is arranged in a linearly gradually increasing height towards the direction away from the exit of the ramp tunnel. By utilizing the visual space to gradually increase from small to large, it not only achieves a reasonable transition in the degree of space from the closed interior to the open exterior of the tunnel, but also mitigates the drastic transition in illuminance, which can reduce the driver's tension about the white hole effect and escape effect at the exit of the ramp tunnel. 2. This invention utilizes a hollowed-out guide arrow design to create arrow-shaped light and shadow on the road surface, which can enhance the guidance of the driver's line of sight. Furthermore, the spacing of the arrow-shaped light and shadow is reasonable, which can prompt the driver to maintain a certain level of alertness and pay attention to the road environment ahead, without causing discomfort. 3. This invention utilizes sound-absorbing panels and a broadcaster to construct an auditory guidance system. The sound-absorbing panels can effectively isolate external noise, reduce noise interference with the driver's driving, and alleviate the driver's escape tension when leaving the tunnel. The broadcaster can provide clear guidance and prompts to the driver through sound signals. The auditory guidance system can provide additional safety assurance to the driver through sound signals in low light or poor visibility conditions, which helps to reduce the occurrence of traffic accidents and improve road driving safety. 4. The combined application of the top hollowed-out guide arrow, the side wall reflective film guide arrow, the road barrier markings, and the two-color vehicle distance adjustment markings of this invention enhances the continuity and consistency of the sunshade canopy and the ramp tunnel exit guidance lines; the road barrier markings strengthen the information guidance on the outer side of the road, enhance the driver's avoidance effect on the edge of the maintenance lane, and pay attention to maintaining the current lane; the two-color vehicle distance adjustment markings increase the distance between vehicles, which has a promoting effect, and at the same time can effectively induce vehicles to decelerate, which helps drivers control their speed when accelerating out of the tunnel.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] This application discloses a combined induced light-shading canopy for the exit of a ramp tunnel. (Refer to...) Figure 1 and Figure 2A combined guiding light-shading canopy for ramp tunnel exits includes a canopy body installed at the ramp tunnel exit, a top visual guidance component installed on top of the canopy body, and side visual guidance components and sound guidance components located on both sides of the canopy body. The canopy body is arranged in a linearly gradually increasing height towards the direction away from the ramp tunnel exit. The top height at the starting point is consistent with the tunnel height, generally 7-9m, and the top height at the ending point is 13m-17m. By utilizing the gradual increase in visual space, it not only achieves a reasonable transition in the degree of spatial enclosure from the tunnel interior to the open exterior, but also mitigates the abrupt transition in illuminance. The main body of the sunshade canopy includes sunshade canopy sidewalls 1 set on both sides of the ramp tunnel, a support frame 2 installed between the two sunshade canopy sidewalls 1, and a sunshade film fixed on the support frame 2. Multiple suspension cables 8 are fixed on the support frame 2. The multiple suspension cables 8 and the support frame 2 together form a stable spatial network structure, which makes the installation of the sunshade film more stable. At the same time, the end of the sunshade film away from the tunnel extends 22~6m from the support frame 2, and the end of the sunshade film away from the support frame 2 is located 0.3~0.6m above the support frame 2.

[0024] Reference Figure 1 and Figure 2 The light-blocking film includes an outer light-blocking film 3 and an inner sun-blocking film 4. The inner sun-blocking film 4 primarily reduces light transition and secondarily reduces glare, mitigating the zebra effect and flicker effect. The top visual guidance component includes multiple sets of hollowed-out guide arrows 5 set on the sun-blocking film 4. Each set of hollowed-out guide arrows 5 corresponds to a lane and is located directly above the corresponding lane, creating a projection on the lane. Multiple hollowed-out guide arrows 5 in the same set are spaced apart along the length of the lane. The hollowed-out guide arrows 5 are 6m long and 0.9m wide, with a 4m interval between adjacent hollowed-out guide arrows 5 in the same set. The light spots after illumination are projected onto the middle of the lane, forming an arrow-shaped light and shadow. The arrow-shaped light and shadow not only enhances the visual guidance of the route, but also, due to the reasonable spacing of the arrow-shaped light and shadow, encourages drivers to maintain a certain level of alertness and pay attention to the road environment ahead, without causing discomfort. The light-shielding film 3 and the sun-shielding film 4 are separated from each other, forming a ventilation channel between them. This allows the airflow within the tunnel, driven by the vehicle as it exits the tunnel, to quickly flow through the perforated guide arrow 5 to the space between the light-shielding film 3 and the sun-shielding film 4, and then exit in a direction away from the tunnel. In one feasible embodiment, the light-shielding film 3 and the sun-shielding film 4 are arranged parallel to each other. In another feasible embodiment, the distance between the light-shielding film 3 and the sun-shielding film 4 gradually increases towards the direction away from the ramp tunnel exit, which can reduce the noise generated by the airflow between the light-shielding film 3 and the sun-shielding film 4 to a certain extent.

[0025] Considering that the arrow-shaped light and shadow formed by the hollowed-out guide arrow 5 in the middle of the driving lane is not clear enough in low light conditions, therefore refer to Figure 3 A lighting system 9 is also installed on the top of the shade structure, located outside the shading film 4. The lighting system 9 includes luminaires mounted on the outside of the shading film 4 and a control component electrically connected to the luminaires. In one feasible embodiment, the control component can only control the on / off state of the luminaires; in another embodiment, the control component integrates a photoresistor to adaptively adjust the lighting intensity of the luminaires by sensing the intensity of light, achieving energy savings while ensuring clear arrow-shaped light and shadow.

[0026] Reference Figure 1 , Figure 2 and Figure 4 A sound-absorbing panel 11 is installed on the side wall 1 of the sunshade canopy. The two ends of the sound-absorbing panel 11 are aligned with the two ends of the side wall 1 of the sunshade canopy. The bottom of the sound-absorbing panel 11 is 0.5m above the ground and flush with the bottom of the tunnel side wall. The width of the sound-absorbing panel 11 is 2.5m. The sound-absorbing panel 11 can effectively isolate external noise, reduce noise interference to the driver, and alleviate the driver's sense of tension when leaving the tunnel.

[0027] To further improve driver guidance in low-light conditions, refer to Figure 1 , Figure 2 and Figure 4 An LED dynamic light strip 10, distributed along the length of the side wall 1 of the shaded canopy, is installed on it. The LED dynamic light strip 10 includes an upper light strip 101 and a lower light strip 102, both of which are stably fixed to a sound-absorbing panel 11. The lower light strip 102 is 1.5m above the ground, and the upper light strip 101 is 2.0m above the ground. A side visual guidance component includes multiple reflective guide arrows 6 mounted on the sound-absorbing panel 11 of the side wall 1 of the shaded canopy. The multiple reflective guide arrows 6 are evenly spaced along the length of the shaded canopy body, and are located between the upper light strip 101 and the lower light strip 102. The reflective guide arrows 6 are 0.4m above the ground, 0.22m wide, and the distance between two adjacent reflective guide arrows 6 is 1.5~2.0m. The LED dynamic light strip 10 and the reflective film guide arrow 6 are unaffected by light intensity and can guide drivers to drive safely. At the same time, the hollow guide arrow 5, the reflective film guide arrow 6 and the LED dynamic light strip 10 work together to enhance the continuity and consistency between the light-shielding canopy and the tunnel exit guidance.

[0028] Reference Figure 1The sound guidance component includes multiple broadcasters 7 installed on the side wall 1 of the sunshade. The multiple broadcasters 7 are evenly distributed along the length of the sunshade body. The broadcasters 7 are fixed below and close to the lower light strip 102. The broadcasters 7 play information such as "Caution: Exit from the tunnel ahead", "Caution: Road conditions ahead", and "Please leave the tunnel area as soon as possible". The content can be flexibly changed according to the real-time situation. The sound-absorbing panel 11 on the side wall 1 of the sunshade and the broadcasters 7 together form auditory guidance, which can provide drivers with additional safety protection through sound signals in the case of insufficient light or poor visibility, which helps to reduce the occurrence of traffic accidents and improve road driving safety.

[0029] Reference Figure 1 A maintenance walkway 12 is provided near the side wall 1 of the sunshade. Road markings 13 are installed on the side of the maintenance walkway 12 facing the driving lane. The standard spacing of the road markings 13 is 0.5m to 0.6m, with yellow markings having a width of no less than 0.3m and black markings having a width of no less than 1.5m. Two-color vehicle distance adjustment markings 14 are also installed at the edge of each driving lane. These markings are laid along the edge of each driving lane, 0.15m away from the lane markings. The two-color markings 14 use a combination of yellow and red colors, spaced 1m apart. The two-color markings 14 are 1m long and 0.15m wide. These markings promote increased vehicle spacing and effectively induce vehicle deceleration. The two-color vehicle distance adjustment markings 14, reflective film guide arrows 6, and road barrier markings 13 are located on the same cross section, extending from the starting point to the ending point of the sunshade body. Road barrier markings 13 and two-color vehicle distance adjustment markings 14 together enhance the visibility and continuity of the driving lane lines at the ramp tunnel exit during both day and night, strengthen information guidance on the outer side of the road, enhance the driver's avoidance effect on the edge of the maintenance lane 12, and encourage drivers to maintain their current lane, thus achieving speed control guidance.

[0030] The implementation principle of a combined guiding sunshade for a ramp tunnel exit according to this application embodiment is as follows: When a vehicle exits the ramp tunnel and enters the sunshade body, the light-blocking film 3 and the sun-shading film 4 can reduce the light intensity of the outside light to a certain extent. Simultaneously, with the assistance of the lighting system 9, the hollowed-out guide arrows 5 on the sun-shading film 4 can project onto the corresponding lane, enhancing visual guidance and prompting the driver to remain alert and pay attention to the road environment ahead. At the same time, the reflective guide arrows 6 and the LED dynamic light strip 10 on the side wall 1 of the sunshade can also guide the driver to drive safely. Furthermore, the sound-absorbing panel 11 on the side wall 1 of the sunshade, together with the broadcaster 7, forms auditory guidance, providing additional safety assurance to the driver through sound signals in situations of insufficient light or poor visibility, helping to reduce traffic accidents and improve road safety.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
