Description

Technical Field

[0001] This utility model relates to the field of tunnel lighting, and in particular to an intelligent lighting device for highway tunnels. Background Technology

[0002] Intelligent lighting devices for highway tunnels are energy-saving lighting equipment that uses sensing and automatic control technologies to control the lighting environment inside the tunnel. They are lighting systems that automatically adjust the lighting conditions of the lamps by monitoring the environment inside the tunnel in real time or by manual control.

[0003] Currently, a Chinese patent with announcement number CN 220191088 U and announcement date of December 15, 2023, proposes an intelligent tunnel lighting device, including a first detection component set at both ends of the tunnel entrance and a second detection component set inside the tunnel. The output terminal of the first detection component is coupled to a timer circuit, and a lighting component is set inside the tunnel. The lighting component includes a basic lighting group set at the tunnel entrance and an enhanced lighting group set deep inside the tunnel. The output terminals of the timer circuit and the second detection component are coupled to a control component for controlling the opening and closing of the enhanced lighting group.

[0004] When in use, the lighting components will provide scene-based lighting for the tunnel environment according to the vehicle traffic conditions inside the tunnel. The basic lighting group provides basic lighting at the tunnel entrance to guide and indicate the location of the tunnel, and the basic lighting group and the enhanced lighting group provide enhanced lighting when vehicles pass through the tunnel.

[0005] Regarding the aforementioned technologies, tunnel lighting fixtures are generally installed on the inner wall of the tunnel. When the fixtures malfunction or require maintenance, traffic control must be implemented within the tunnel before maintenance can be carried out. However, due to the poor lighting environment and limited visibility within the tunnel, implementing traffic control inside the tunnel would greatly increase the risk of traffic accidents, thereby posing a safety risk to the maintenance of the tunnel lighting fixtures. Utility Model Content

[0006] In order to reduce the safety risks when maintaining the lighting fixtures inside the tunnel, this utility model provides an intelligent lighting device for highway tunnels.

[0007] This utility model provides an intelligent lighting device for highway tunnels, which adopts the following technical solution:

[0008] A smart lighting device for highway tunnels includes: a guide rail, a lamp holder, a locking assembly, and a lighting fixture assembly; the guide rail is arc-shaped and fixedly mounted on the inner wall of the tunnel along its circumference; the lamp holder is slidably mounted on the guide rail, and the locking assembly is fixedly mounted on the lamp holder, the locking assembly being used to lock the position of the lamp holder in conjunction with the guide rail; the lighting fixture assembly is fixedly mounted on the lamp holder and is connected to an external power source for illumination.

[0009] By adopting the above technical solution, during installation, the guide rail is fixed to the inner wall of the tunnel with screws. Next, the lighting components are fixed to the light fixture. Then, the light fixture is installed on the guide rail and secured to it with ropes or operating rods, allowing the light fixture to slide and adjust its position on the guide rail. Finally, after adjusting the light fixture to the appropriate position, the locking components are used to fix it in place, completing the installation. When subsequent maintenance or replacement of the lighting fixture is required, first loosen the locking components to allow the light fixture to slide on the guide rail. Then, use tools to move the control light fixture along the guide rail to the bottom, allowing maintenance or replacement of the lighting components on the light fixture. After maintenance or replacement, use tools to reset the light fixture and use the locking components to fix it in place.

[0010] In this way, by setting up guide rails and locking components, the lamps can move and be fixed on the inner wall of the tunnel along with the lamp holder. When maintaining the lamp components, the lamps can be moved to the bottom of the guide rail at the edge of the tunnel, eliminating the need for traffic control inside the tunnel. This reduces the risk of traffic accidents caused by lamp maintenance and improves safety.

[0011] Optionally, the locking component includes a slider and a fastener. The slider is slidably mounted on the guide rail, and the lamp holder is slidably mounted on the slider. The lamp holder moves closer to or away from the guide rail. The fastener is used to lock the relative position of the slider and the guide rail. The guide rail is provided with a slot, and the lamp holder is provided with a locking tooth. When the lamp holder moves closer to the guide rail, the locking tooth is inserted into the slot.

[0012] By adopting the above technical solution, when adjusting the relative position of the lamp holder, firstly, the fasteners are loosened; secondly, the lamp holder is moved away from the guide rail, causing the locking teeth to disengage from the slots; finally, the lamp holder slides on the sliding component. When the lamp holder slides to the corresponding position, the fasteners are tightened, causing the lamp holder to press against the guide rail, so that the locking teeth on the lamp holder engage in the slots, thus locking the lamp holder relative to the guide rail. In this way, the engagement between the locking teeth on the lamp holder and the slots on the guide rail provides reliable locking, allowing the lamp holder to be moved along the guide rail to the edge for maintenance, reducing the impact on tunnel traffic. After maintenance is completed, the lamp holder can be used to lock the lamp in a set position, improving the stability of the lamp.

[0013] Optionally, both the teeth and the edges of the slots are provided with an automatic alignment structure.

[0014] By adopting the above technical solution, the automatic alignment structure (such as a ramp or guide groove) of the locking teeth and the edge of the slot allows the locking teeth to slide into the slot when the lamp holder is moved towards the guide rail during locking. Thus, during operation, maintenance personnel only need to roughly move the lamp holder, and then the fasteners tighten the lamp holder towards the guide rail. The automatic alignment structure helps the locking teeth easily insert into the slot, eliminating the need for fine adjustments in the dimly lit tunnel environment. This design simplifies the locking process, reduces operation time and the probability of error, and improves maintenance efficiency in low-light environments.

[0015] Optionally, the guide rail is provided with a guide groove, which is provided along the length direction of the guide rail, and one end of the sliding member is provided with a guide wheel, which is disposed inside the guide groove.

[0016] By adopting the above technical solution, maintenance personnel can pull the light fixture, causing the guide wheels to roll within the guide grooves of the guide rail. This movement of the sliding components and the light fixture allows the light fixture to easily slide to the bottom of the guide rail or return to its locked position, reducing pushing and pulling resistance. In this way, the guide wheel and guide groove structure achieves low-resistance sliding, facilitating the movement of the light fixture in narrow tunnel spaces, reducing operational effort, and shortening maintenance time.

[0017] Optionally, a support platform is provided below the guide groove, and the guide wheel is supported above the support platform.

[0018] By adopting the above technical solution, the support platform is located below the guide groove. When the guide wheel rolls, it is supported on the support platform. The support platform supports the guide wheel above and bears the weight of the lamp holder, so that the support platform provides additional load for the guide wheel and the lamp holder, enhances the overall stability, and makes the lamp holder installation safer and more reliable.

[0019] Optionally, a connecting plate is provided at the end of the sliding member away from the guide wheel, and a positioning groove is provided in the middle of the lamp holder. The connecting plate is slidably disposed in the positioning groove along the thickness direction of the positioning groove. A threaded hole is provided in the middle of the connecting plate, and a corresponding through hole is provided at the bottom of the positioning groove. The fastener is a lifting eye bolt, and the fastener passes through the through hole and is connected to the threaded hole.

[0020] By adopting the above technical solution, the connecting plate slides along the depth direction of the positioning groove in the lamp holder, allowing the lamp holder to move closer to or away from the guide rail. The lifting eye bolt passes through the through hole of the lamp holder and is screwed into the threaded hole of the connecting plate. Rotating the lifting eye bolt, combined with gravity, controls the lamp holder to move away from or closer to the guide rail, causing the locking teeth to engage with the locking slot for locking. During operation, maintenance personnel can lock or loosen the connecting plate and lamp holder by hanging a hand crank with a hook at the end on the lifting eye and rotating the hand crank to rotate the lifting eye bolt. This design of the lifting eye bolt simplifies the tightening operation, shortens maintenance preparation time, and improves the efficiency of working in the tunnel.

[0021] Optionally, the lighting assembly includes a visibility sensor, an LED luminaire, and a fog light luminaire, all of which are mounted on the lamp holder.

[0022] By adopting the above technical solution, the visibility sensor detects the level of fog or dust in the tunnel and automatically controls the LED lights or fog lights to switch lighting, providing sufficient light according to the environment, optimizing the lighting effect in the tunnel, reducing the probability of accidents caused by insufficient lighting due to low visibility in the tunnel, and improving overall safety.

[0023] Optionally, the lamp holder is also provided with a clamp for fixing the cable.

[0024] By adopting the above technical solution, the clamp securely holds the power cable of the lamp assembly to the lamp holder; during maintenance, the cable moves with the lamp holder, which reduces the probability of the cable coming loose and ensures that the maintenance work is carried out smoothly and safely.

[0025] In summary, this utility model has at least one of the following beneficial technical effects:

[0026] By setting up guide rails and locking components, the luminaires can move and be fixed on the inner wall of the tunnel along with the luminaire holder. When maintaining the luminaire components, the luminaires can be moved to the bottom of the guide rail at the edge of the tunnel, eliminating the need for traffic control inside the tunnel. This reduces the risk of traffic accidents caused by luminaire maintenance and improves safety.

[0027] By setting locking teeth on the lamp holder and corresponding locking slots on the guide rail, the engagement of the locking teeth on the lamp holder and the locking slots on the guide rail can provide reliable locking. This allows the lamp holder to be moved along the guide rail to the edge position for maintenance, reducing the impact on traffic in the tunnel. After the maintenance of the lamp is completed, the locking teeth and locking slots can lock the lamp holder and lamp in the set position, improving the stability of the lamp.

[0028] By setting an automatic alignment structure on the edges of the teeth and slots, the teeth can be easily inserted into the slots without the need for fine adjustments in the dim tunnel environment. This simplifies the lamp holder locking process, reduces operation time and the probability of errors, and improves the efficiency of maintenance in low-light environments.

Detailed Implementation

[0036] The following combination Figures 1 to 6 The present invention will be described in further detail below.

[0037] This utility model discloses an intelligent lighting device for highway tunnels. (Refer to...) Figures 1 to 3A smart lighting device for highway tunnels mainly includes an arc-shaped guide rail 100 fixedly installed on the inner wall of the tunnel, a lamp holder 200 that can slide along the guide rail 100, a locking component 300 for locking the lamp holder 200 at a specific position on the guide rail 100, and a lighting assembly 400 installed on the lamp holder 200 to provide illumination. During installation, the guide rail 100 is fixed to the inner wall along the circumference of the tunnel, the lamp holder 200 is slidably mounted on the guide rail 100 through the locking component 300, and the lighting assembly 400 is fixed to the lamp holder 200 and connected to an external power source. When the lighting fixtures are repaired or replaced, maintenance personnel can loosen the locking component 300, allowing the lamp holder 200 and the lighting assembly 400 to slide along the arc-shaped guide rail 100 to the edge position such as the tunnel sidewall or bottom for maintenance operations. After completion, the lamp holder 200 is reset and relocked. Maintenance operations do not require the occupation of the driving lanes inside the tunnel, significantly reducing the risk of traffic accidents.

[0038] Reference Figure 3 and Figure 4 The guide rail 100 serves as the basic load-bearing structure for the movement and positioning of the entire device. Specifically, the guide rail 100 is arc-shaped and matches the inner wall of the tunnel. The guide rail 100 is fixed to the inner wall of the tunnel along the circumference by fasteners such as screws 320. A guide groove 102 extending along its length is provided in the middle of the guide rail 100. A support platform 103 is also provided below the guide groove 102. When the lamp holder 200 and the locking component 300 slide on the guide rail 100, the lamp holder 200 and the locking component 300 are supported on the support platform 103 to bear the load transmitted by the subsequent sliding component 310 and the lamp holder 200, thereby enhancing the overall stability. The lamp holder 200 slides in the guide groove 102, providing a preset trajectory for its movement.

[0039] Reference Figure 5 and Figure 6 The locking component 300 includes a slider 310 and a fastener 320. The slider 310 is connected to the lamp holder 200 via the fastener 320, making the slider 310 a sliding connector between the lamp holder 200 and the guide rail 100. One end of the slider 310 is provided with a guide wheel 311, which is located inside the guide groove 102 of the guide rail 100 and supported on the support platform 103 below the guide groove 102. The other end of the slider 310 away from the guide wheel 311 is fixedly provided with a connecting plate 312, and the connecting plate 312 has a through threaded hole 313 in the middle. The fastener 320 is a lifting eye bolt, which is connected to the threaded hole 313 in the middle of the connecting plate 312.

[0040] Reference Figure 3 and Figure 6The lamp holder 200 has a positioning groove 202 in the middle. The positioning groove 202 matches the connecting plate 312 on the sliding member 310, so that the connecting plate 312 is slidably disposed in the positioning groove 202 and can slide in the positioning groove 202 along the depth direction of the positioning groove 202. The bottom of the positioning groove 202 of the lamp holder 200 has a through hole 203. The eye bolt passes through the through hole 203 of the lamp holder 200 and is connected (screwed) into the threaded hole 313 of the connecting plate 312. When the eye bolt is tightened or loosened, the eye bolt can drive the lamp holder 200 to move closer to or away from the guide rail 100 under the action of gravity.

[0041] Reference Figure 4 and Figure 5 A locking tooth 201 is provided on the side of the lamp holder 200 facing the guide rail 100. Correspondingly, a slot 101 is provided on the guide rail 100 to cooperate with the locking tooth 201 of the lamp holder 200. The edges of the locking tooth 201 and the slot 101 are provided with an automatic alignment structure. In this embodiment, both the locking tooth 201 and the slot 101 are set with arc-shaped edges, and their edges form an automatic alignment structure. When it is necessary to lock the position of the lamp holder 200, tighten (forward tightening) the eye bolt, and the resulting tightening force will lock the lamp holder 200. Pull the light fixture 200 towards the guide rail 100. During this process, the locking teeth 201 and the edge of the slot 101 interact with each other, automatically guiding the locking teeth 201 into the slot 101 to achieve engagement and locking. When it is necessary to unlock and move the light fixture 200, loosen (reverse unscrew) the eye bolt. The light fixture 200 moves away from the guide rail 100 under the action of gravity. The locking teeth 201 disengage from the slot 101. At this time, the light fixture 200 can slide freely on the guide rail 100 through the sliding member 310.

[0042] Since the installation position of the lamp holder 200 is far from the ground, the operator cannot stand on the ground to directly contact the eye bolt. In this embodiment, when the operator rotates the eye bolt, it is done by a hand crank with a hook. During the operation, the hook at the end of the hand crank is hung on the eye of the eye bolt, and then the hand crank is rotated to drive the eye bolt to rotate. At the same time, when controlling the movement of the lamp holder 200, the lamp holder 200 is controlled to slide on the guide rail 100 by pulling or pushing the hand crank.

[0043] Reference Figure 5 and Figure 6The lighting assembly 400 includes an LED lamp 420 for main lighting, a fog lamp 430 for enhanced penetration lighting in foggy or low-visibility environments, and a visibility sensor 410 for detecting environmental conditions inside the tunnel. In this embodiment, the LED lamp 420 uses white light, the fog lamp 430 uses yellow light, and the visibility sensor 410 is a light sensor. The light sensor is equipped with a transmitter and a receiver. The receiver detects the visibility by detecting the intensity of the light emitted by the transmitter. The stronger the received light, the better the visibility. During operation, the visibility sensor 410 continuously monitors factors affecting visibility, such as fog and smoke inside the tunnel, and automatically controls the LED lamp 420 and the fog lamp 430 to turn on, off, or adjust their brightness according to preset thresholds and control logic. For example, LED lights 420 are used primarily for illumination under normal visibility conditions; when visibility decreases, the brightness of fog lights 430 is automatically increased or fog lights are turned on to provide drivers with a clearer and safer lighting environment and reduce the risk of accidents.

[0044] In this embodiment, the lamp holder 200 is also provided with a clamp 210 for organizing cables. The clamp 210 is used to fix the power cable of the lamp assembly 400, so that the power cable of the lamp moves with the lamp holder 200, thereby reducing the probability of the cable becoming loose and tangled during the movement or maintenance of the lamp holder 200.

[0045] The implementation principle of the intelligent lighting device for highway tunnels in this embodiment of the utility model is as follows:

[0046] Initial Installation and Locking: First, fix the arc-shaped guide rail 100 circumferentially along the inner wall of the tunnel using screws and other fasteners 320; install the lighting components 400 (LED lights 420, fog lights 430, visibility sensors 410) on multiple light holders 200, and secure the power cables with clamps 210 on the light holders 200; then, place the light holder 200 onto the connecting plate 312 of the sliding member 310 through the positioning groove 202, and screw the eye bolt through the through hole 203 of the light holder 200 into the threaded hole 313 of the connecting plate 312, at which point the bolt can be in a semi-tight state; next, place the guide wheel 311 at the front end of the sliding member 310 into the guide groove 102 of the guide rail 100, so that the guide wheel 311 is supported on the support platform 103 below the guide groove 102; push the light holder 200 with the hand crank, so that the light holder 200 moves along the guide rail 100 circumferentially. 00 Slides to the preset lighting position; after the lamp holder 200 reaches the set position, use the hand crank with the hook to rotate the eye of the eye bolt and tighten the eye bolt; during the tightening process, the eye bolt pulls the lamp holder 200 towards the guide rail 100, so that the locking teeth 201 on the lamp holder 200 are inserted into the slots 101 of the guide rail 100 to achieve locking; the edges of the locking teeth 201 and the slots 101 are provided with automatic alignment arc surfaces. During the movement of the lamp holder 200, the locking teeth 201 are guided to be inserted into the slots 101, so that the locking teeth 201 are smoothly inserted into the slots 101 and engaged and locked; at this time, the relative positions of the lamp holder 200, the sliding member 310 and the guide rail 100 are firmly fixed, the lamp assembly 400 is in the working position, and the visibility sensor 410 controls the LED lamp 420 or the fog light 430 to provide appropriate lighting according to the environment.

[0047] Maintenance Operation (Unlocking and Movement): When maintenance or replacement of the lighting assembly 400 is required, maintenance personnel do not need to enter the driving lane. At the tunnel edge or in a safe area, the operator uses a hand crank to connect the lifting eye bolt to the lifting eye. By rotating the hand crank, the lifting eye bolt is loosened. Under the influence of gravity, the lamp holder 200 moves the locking teeth 201 along the automatic alignment ramp away from the guide rail 100, causing the locking teeth 201 to disengage from the slot 101 of the guide rail 100, releasing the engagement lock. At this time, the lamp holder 200 maintains a sliding connection with the guide rail 100 through the sliding member 310. Personnel pull the lamp holder 200 with a hand crank. The guide wheel 311 on the sliding member 310 rolls smoothly along the support platform 103 in the guide groove 102 of the guide rail 100, driving the entire lamp holder 200 to slide along the arc-shaped guide rail 100 to the safe area at the bottom of the guide rail 100. Due to the cooperation between the guide wheel 311, the guide groove 102, and the support platform 103, the movement resistance is small, and the lamp holder 200 can be easily slid to the edge position such as the tunnel side wall or bottom, which is convenient for operation and does not affect traffic. The power cable of the lamp assembly 400 moves with the lamp holder 200 and is kept fixed by the clamp 210.

[0048] In summary, this application, by setting the guide rail 100 and locking component 300, enables the lamp to move and be fixed on the inner wall of the tunnel along with the lamp holder 200. When maintaining the lamp assembly 400, the lamp can be moved to the bottom of the guide rail 100 at the tunnel edge, eliminating the need for traffic control within the tunnel, reducing the risk of traffic accidents caused by lamp maintenance, and improving safety. Furthermore, the lamp holder 200 is provided with locking teeth 201, and the guide rail 100 is provided with corresponding locking slots 101. The engagement of the locking teeth 201 on the lamp holder 200 and the locking slots 101 on the guide rail 100 provides reliable locking, ensuring secure maintenance. During maintenance of the lamp holder 200, it can be moved along the guide rail 100 to the edge position for maintenance, reducing the impact on traffic in the tunnel. After the maintenance of the lamp is completed, the lamp holder 200 and the lamp can be locked in the set position by the locking teeth 201 and the locking slot 101, improving the stability of the lamp. An automatic alignment structure is set at the edge of the locking teeth 201 and the locking slot 101. The automatic alignment structure can help the locking teeth 201 easily insert into the locking slot 101 without fine adjustment in the dim environment of the tunnel. This simplifies the locking process of the lamp holder 200, reduces operation time and the probability of error, and improves the efficiency of maintenance in low light environment.

[0049] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
