Description

Technical Field

[0001] The present application relates to the technical field of tunnel anti-collision warning technology, and in particular to an anti-collision warning device based on a two-way ramp tunnel of a highway. Background Art

[0002] With the rapid development of expressway construction in my country, ramp tunnels are becoming increasingly prominent within the expressway system. As a crucial transportation hub, ramp tunnels connect different expressways and facilitate traffic transfers. However, expressway ramps are complex, often leading to vehicle collisions during turns at interchanges due to improper driver operation or complex road conditions. The existing black-and-white tunnel effect in expressway ramp tunnels, combined with light interference and unclear guidance at the tunnel entrance, further exacerbates accidents such as vehicle collisions at bends. Therefore, a device that can effectively prevent traffic accidents in ramp tunnels is being developed. By adding a collision warning device within the driver's line of sight near the tunnel entrance, accidents caused by excessive speed, light interference at the tunnel entrance, and unclear guidance are effectively avoided.

[0003] my country has already implemented several measures to address traffic safety issues in ramp tunnels, such as installing traffic lights, traffic signs, and warning signs. However, these measures still face some shortcomings in practical application. First, due to distracted drivers and insufficient driving experience, drivers may fail to promptly detect traffic lights or warning signs at tunnel entrances, resulting in accidents. Second, existing traffic safety facilities may be slow to respond and ineffective in responding to emergencies such as inclement weather and icy roads. Furthermore, existing anti-collision warning devices lack intelligence and automation, and are unable to respond promptly and accurately to various complex traffic conditions. Furthermore, they are not fully applicable to different tunnel entrances, making them difficult to replicate and promote. This series of issues makes the installation of anti-collision warning devices in ramp tunnels extremely difficult. Summary of the Invention

[0049] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will be combined with the appended claims of the present invention. Figure 1-5 , clearly and completely describing the technical solutions of the present invention. Obviously, the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0050] Reference Figure 1 、 Figure 2 and Figure 5, the embodiment of the present application discloses an anti-collision warning device based on a two-way ramp tunnel of a highway, which includes a grating reflective guidance device body and a stretchable adjustable support frame;

[0051] The main body of the grating reflective guidance device includes a plurality of guidance sub-bodies 1 connected in sequence along the extension direction of the tunnel. The guidance sub-bodies 1 include:

[0052] The LED middle screen 11 is arranged on the side facing the tunnel entrance;

[0053] The diffuse reflective material edge screen 12 is arranged around the LED middle screen 11;

[0054] The full screen 13 of the diffuse reflective material is arranged at an angle to the edge screen 12 of the diffuse reflective material, and the angle between the two is adjustable. The full screen 13 of the diffuse reflective material is hinged to the edge screen 12 of the diffuse reflective material in the adjacent guide body 1;

[0055] The stretchable and adjustable support frame includes:

[0056] The support shaft 2 is provided in plurality and is arranged in one-to-one correspondence with the plurality of guide split bodies 1. The diffuse reflective material edge screen 12 and the opposite diffuse reflective material full screen 13 in the same guide split body 1 are both hinged on the support shaft 2;

[0057] A detachable support frame 3 is provided along the arrangement direction of the plurality of guide segments 1 and is used for fixed connection with the tunnel side wall;

[0058] There are multiple back-type main body fixing devices, which are arranged in a one-to-one correspondence with the multiple support shafts 2, one end of which is fixed to the support shaft 2 and the other end is slidably arranged on the detachable support frame 3; and

[0059] The angle adjustment mechanism 4 is used to adjust the angle between the diffuse reflection material edge screen 12 and the opposite diffuse reflection material full screen 13.

[0060] Among them, multiple LED intermediate screens 11 form a three-dimensional, complete information display screen in the direction of the tunnel entrance. The LED intermediate screen 11 is configured to display accidents ahead, road construction reminders, or tunnel linear guidance signs in bad weather, and is configured to reduce brightness or turn off when visibility is good.

[0061] After such a setting, first, the angle between the diffuse reflective material edge screen 12 and the opposite diffuse reflective material full screen 13 in the multiple guide splits 1 can be adjusted through the angle adjustment mechanism 4 to change the installation angle of the guide split 1 on the tunnel side wall to adapt to different tunnel side wall angles, effectively reducing the cost of engineering application and improving practical applicability. Secondly, the diffuse reflective material edge screen 12 uses the material properties to complete the auxiliary diffuse reflection of light, which can display the outline of the ramp tunnel and the direction of travel. The LED middle screen 11 is used to assist the diffuse reflective material edge screen 12 to remind the driving environment when the outline of the ramp tunnel and the direction of travel cannot be fully displayed in bad weather. The multi-screen effect of the LED middle screen 11 can achieve a more suitable ramp tunnel line shape and three-dimensional induction effect under the special driving environment of the ramp tunnel. Moreover, when the visibility in the tunnel is good, the LED middle screen 11 reduces the brightness or turns off, which can achieve a good energy-saving effect.

[0062] Therefore, with the help of the display content of the LED middle screen 11, the anti-collision warning effect of the highway ramp tunnel can be achieved, and the auxiliary display effect and emergency backup anti-collision warning effect can be displayed through the diffuse reflection material edge screen 12. At the same time, the opposite diffuse reflection material full screen 13 also reaches the guidance warning display conditions of the ramp tunnel exit section, which can play a comprehensive anti-collision warning effect.

[0063] Specifically, refer to Figure 3 and Figure 4 , the above-mentioned angle adjustment mechanism 4 includes:

[0064] Two fixing seats 41 are provided and are located at both ends of the detachable support frame 3. One of the fixing seats 41 is fixed to the lower end of the diffuse reflective material edge screen 12 near the tunnel entrance, and the other is fixed to the lower end of the diffuse reflective material full screen 13 facing away from the tunnel entrance.

[0065] An adjustment chain 42 is arranged along the arrangement direction of the plurality of guide segments 1, with one end thereof being fixedly connected to a fixing seat 41 near the tunnel entrance;

[0066] An adjusting wheel 43 is rotatably mounted on a fixed seat 41 facing away from the tunnel entrance and is meshed with an adjusting chain 42. A turning handle 48 is provided on the adjusting wheel 43. Specifically, a gap is reserved between the adjusting wheel 43 and the fixed seat 41 for the adjusting chain 42 to pass through. This means that the adjusting wheel 43 can smoothly drive the adjusting chain 42 to move left and right when it rotates.

[0067] The locking assembly is used to lock the adjusting wheel 43 .

[0068] Furthermore, an adjustment cylinder 44 is hingedly connected to the bottom of each of the diffuse reflection material edge screen 12 and the opposite diffuse reflection material full screen 13 , which are away from the corresponding support shaft 2 , and an adjustment chain 42 is provided through the adjustment cylinder 44 .

[0069] Furthermore, the locking assembly includes:

[0070] The locking tooth 45 is slidably disposed on the fixed seat 41 away from the tunnel entrance, and its sliding direction points to the adjustment wheel 43. The locking tooth 45 is meshed with the adjustment wheel 43, and a shifting block 47 is provided on the locking tooth 45;

[0071] The elastic member 46 is provided on the fixed seat 41, with one end thereof abutting against the fixed seat 41 and the other end abutting against the lock tooth 45. When the lock tooth 45 abuts against the tooth groove on the adjusting wheel 43, the elastic member 46 is in a compressed state. Specifically, the elastic member 46 is configured as a spring, and a long rod slidably provided on the fixed seat 41 is fixedly connected to the side of the lock tooth 45 facing away from the adjusting wheel 43, and the spring is sleeved on the long rod.

[0072] In this way, when it is necessary to adjust the angle between the edge screen 12 of the diffuse reflection material and the full screen 13 of the opposite diffuse reflection material, the dial block 47 can be toggled to disengage the lock tooth 45 from the engagement with the adjustment wheel 43. At this time, the handle 48 can be turned so that the adjustment wheel 43 rotates and drives the adjustment chain 42 to move, which can change the actual length of the adjustment chain 42 between the two fixed seats 41. The angle adjustment between the edge screen 12 of the diffuse reflection material and the full screen 13 of the opposite diffuse reflection material in the multiple guiding splits 1 can be achieved by changing the length of the adjustment chain 42.

[0073] And, refer to Figure 5 , the back-type main body fixing device includes:

[0074] The sliding sleeve 51 is slidably disposed on the detachable support frame 3. The detachable support frame 3 may be a rod-shaped object with a non-circular cross section, such as a square tube or angle steel, to prevent the sliding sleeve 51 from flipping over on the detachable support frame 3.

[0075] A fixing rod 52, one end of which is fixed to the support shaft 2 and the other end of which is bolted to the sliding sleeve 51; and

[0076] The adjusting screw 53 is threadedly mounted on the sliding sleeve 51 , and its head end is tightly pressed against the detachable support frame 3 .

[0077] In this way, by bolting the fixing rod 52 to the sliding sleeve 51, convenient installation, maintenance and replacement of multiple guiding splits 1 can be achieved; the sliding sleeve 51 slides on the detachable support frame so that the angle between the diffuse reflection material edge screen 12 and the opposite diffuse reflection material full screen 13 will not be stuck during adjustment, and when the position adjustment of the sliding sleeve 51 is completed, the adjusting screw 53 can be tightened on the detachable support frame 3 to achieve locking of the sliding sleeve 51, and then the guiding split 1 is locked after the angle and position adjustment are completed, thereby improving the stability and wind resistance of the present application.

[0078] The implementation principle of the anti-collision warning device based on a two-way ramp tunnel on a highway in the embodiment of the present application is as follows:

[0079] The angle between the diffuse reflective material edge screen 12 and the opposite diffuse reflective material full screen 13 in the multiple guide segments 1 is adjusted through the angle adjustment mechanism 4 to change the installation angle of the guide segments 1 on the tunnel sidewall to adapt to different tunnel sidewall angles, effectively reducing the cost of engineering application and improving practical applicability. Secondly, the diffuse reflective material edge screen 12 uses the material properties to complete the diffuse reflection of light to assist in displaying the outline of the ramp tunnel and the direction of travel. The LED middle screen 11 is used to assist the diffuse reflective material edge screen 12 to remind the driving environment when the ramp tunnel outline and the direction of travel cannot be fully displayed in bad weather. The multi-screen effect of the LED middle screen 11 can achieve a more consistent linear shape of the ramp tunnel and a three-dimensional guidance effect under the special driving environment of the ramp tunnel.

[0080] Furthermore, when visibility is good in the tunnel, the LED center screen 11 can be dimmed or turned off, achieving significant energy savings. Therefore, the display content of the LED center screen 11 can achieve a collision avoidance warning effect in highway ramp tunnels. The diffuse reflective edge screen 12 provides auxiliary display effects and emergency backup collision avoidance warning effects. Simultaneously, the diffuse reflective full screen 13 also provides guidance and warning display conditions for the ramp tunnel exit section, providing a comprehensive collision avoidance warning effect.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
