[0033] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts should fall within the scope of protection of the present invention.

[0034] See also Figures 1 to 9As shown, a lighting automation energy-saving device suitable for highway tunnels, the lighting device has multiple groups, and the multiple groups of lighting devices are equidistantly installed on the inner walls of both sides of the tunnel; each group of lighting devices includes an arc guide rail 1, an arc block 2, a fixing mechanism 3, a lighting mechanism 4, a moving mechanism 5 and a conductive mechanism 6; the arc guide rail 1 is fixedly arranged on the inner wall of the tunnel, and the arc block 2 can be slidably arranged in the corresponding arc guide rail 1, and a mounting hole 21 is provided at the center of the side of the arc block 2 away from the bottom inner wall of the arc guide rail 1, and a sliding column 22 is slidably arranged in the mounting hole 21, and a horizontal plate 221 is provided at one end of each sliding column 22 away from the mounting hole 21, and an arc-shaped lower pressure plate 222 is provided on one side of the horizontal plate 221, the fixing mechanism 3 is arranged on the arc guide rail 1 and is used to make the arc-shaped lower pressure plate 222 fit the surface of the arc guide rail 1; the lighting mechanism 4 is arranged on the horizontal plate 221; the moving mechanism 5 is arranged in the arc guide rail 1 and is used to push the arc block 2 to move, and an arc-shaped through hole 22 is provided inside the arc guide rail 1 Slot 11, mounting slots 12 connecting to the inside of the arc-shaped through-slot 11 are provided at both ends of the arc-shaped guide rail 1, the moving mechanism 5 includes two rotating shafts 51 rotatably arranged in the corresponding mounting slots 12, and the two rotating shafts 51 are connected by a synchronous belt 52. A side of each arc block 2 close to the arc-shaped guide rail 1 is provided with an avoidance slot 23 for avoiding the synchronous belt 52, and each synchronous belt 52 is equidistantly provided with a plurality of elastic telescopic rods 53 corresponding to the mounting holes 21; arc grooves 13 are provided on the inner walls on both sides of the arc-shaped guide rail 1, and an arc-shaped conductive sheet 14 is provided in each arc groove 13; rectangular slots 24 are provided on both sides of the arc block 2, and the conductive mechanism 6 is provided in the rectangular slot 24 and is used to power the lighting mechanism 4; each group of conductive mechanisms 6 includes two sliding blocks 61 slidably arranged in the corresponding rectangular slots 24, and the two sliding blocks 61 can approach or move away from each other as the sliding column 22 moves, and the two sliding blocks 61 are provided with conductive columns 62 cooperating with the arc-shaped conductive sheet 14 on the away sides.

[0035] A plurality of arc guide rails 1 are equidistantly arranged on the inner walls on both sides of the tunnel, and the arc-shaped conductive sheets 14 on the inner walls on both sides of the arc guide rails 1 are electrically connected to the cables in the tunnel respectively, and the two arc-shaped conductive sheets 14 are respectively connected to the neutral line and the live line of the cable; by adjusting the rotating shaft 51, the rotating shaft 51 is rotated, and the two rotating shafts 51 are connected by a synchronous belt 52 for transmission. According to the width of the tunnel, a corresponding number of arc blocks 2 are added, and a corresponding number of arc blocks 2 are placed in the arc guide rail 1, and the elastic telescopic rod 53 on the synchronous belt 52 is extended into the corresponding mounting hole 21, so that the corresponding number of arc blocks 2 can be separated by a certain distance to ensure the illumination range of the light. At this time, the synchronous belt 52 is located in the corresponding avoidance groove 23, and the arc-shaped through groove 11 is used for the synchronous belt 52 to pass through, thereby ensuring that the synchronous belt 52 can rotate; at this time, as the synchronous belt 52 moves, the arc block 2 can move along with the synchronous belt 5 2 is moved, and after it is moved to the corresponding height, the arc-shaped lower pressing plates 222 on the corresponding number of arc-shaped blocks 2 are pressed down by the fixing mechanism 3, so that the arc-shaped lower pressing plates 222 are fitted into the surface of the arc-shaped guide rail 1, thereby fixing the arc-shaped blocks 2. At this time, the sliding posts 22 move along the corresponding mounting holes 21, thereby squeezing the elastic telescopic rods 53 extending into the corresponding mounting holes 21, thereby pushing the elastic telescopic rods 53 out of the mounting holes 21, and the two sides of the avoidance grooves 23 are set as rounded corners, thereby ensuring the smooth movement of the elastic telescopic rods 53; as the elastic telescopic rods 53 move out of the mounting holes 21, the synchronous belt 52 can continue to move, and as the sliding posts 22 move, the two sliding blocks 61 can move away from each other, so that the conductive posts 62 on the sliding blocks 61 can contact the corresponding arc-shaped conductive sheets 14, which can not only fix the arc-shaped blocks 2 for a second time, but also supply power to the lighting mechanism 4.

[0036] When maintenance is needed, the staff does not need to block the tunnel. They only need to adjust the synchronous belt 52 on the high platforms on both sides of the tunnel so that the elastic telescopic rod 53 on the synchronous belt 52 moves to the bottom of the corresponding mounting hole 21 of the corresponding arc block 2, and the arc-shaped lower pressure plate 222 is moved away from the arc guide rail 1 through the fixing mechanism 3. At this time, the two sliding blocks 61 approach each other and retract into the corresponding rectangular grooves 24. The sliding column 22 moves away from the bottom inner wall of the arc guide rail 1. The elastic telescopic rod 53 set on the synchronous belt 52 can be extended into the corresponding mounting hole 21. When the power is cut off, the arc block 2 can rotate synchronously with the synchronous belt 52, so that in the case of local power outages, it is convenient to maintain the lighting mechanism 4, ensuring that the tunnel can continue to operate, avoiding traffic jams, and reducing the risk of traffic accidents.

[0037] It should be noted that in the present application, the diverging side refers to a side away from each other, and the facing side refers to a side close to each other.

[0038] See also Figures 6 to 9As shown, the conductive mechanism 6 also includes a return spring 63 and a limit plate 64; a limit plate 64 is provided at the open end of each rectangular slot 24, and each limit plate 64 is provided with a guide hole 641 for the conductive column 62 to pass through, and each conductive column 62 is sleeved with a return spring 63, and the return spring 63 is located between the corresponding sliding block 61 and the limit plate 64; a fixed groove 211 is provided on the inner wall of each mounting hole 21, and a fixed block 223 that cooperates with the fixed groove 211 is provided on the outer wall of each sliding column 22, and the fixed block 223 can be slidably arranged in the corresponding fixed groove 211, and a limit plate 25 is provided at the end of each arc block 2, and a limit hole 251 for the sliding column 22 to pass through is provided at the center of the limit plate 25, and the facing sides of the two sliding blocks 61 are provided with triangular guide surfaces 611, and each sliding column 22 is provided with a conical protrusion 224 that cooperates with the triangular guide surface 611 at one end close to the mounting hole 21.

[0039] The two sliding blocks 61 are V-shaped. Under the elastic force of the return spring 63, the two conductive columns 62 can be retracted into the corresponding rectangular grooves 24, thereby ensuring the smooth movement of the arc block 2. When the arc block 2 moves to the corresponding position, the arc-shaped lower pressure plate 222 is pressed down, so that the sliding column 22 moves. Through the cooperation of the fixed block 223, the fixed groove 211 and the limit plate 25, not only the stability of the movement of the sliding column 22 can be ensured, but also the position of the sliding column 22 can be limited to prevent it from falling off. As the sliding column 22 moves, the conical protrusion 224 at the end of the sliding column 22 can contact the triangular guide surface 611 on the two sliding blocks 61, so that the two sliding blocks 61 overcome the corresponding The elastic force of the reset spring 63 moves away from each other, allowing the conductive column 62 to contact the corresponding arc-shaped conductive piece 14, thereby powering the lighting mechanism 4 while allowing the sliding column 22 to contact the elastic telescopic rod 53 extending into the mounting hole 21, so that the elastic telescopic rod 53 can be moved out of the mounting hole 21, thereby ensuring the stability of the movement of the synchronous belt 52. Similarly, when maintenance is required, the fixing mechanism 3 is separated from the arc-shaped lower pressure plate 222, and under the action of the elastic force of the reset spring 63, the conductive column 62 can be reset, ensuring that the arc block 2 can move synchronously with the elastic telescopic rod 53 on the synchronous belt 52, which is not only convenient for staff to perform maintenance, but also can perform local power outages during maintenance to ensure the safety of staff.

[0040] See also Figure 2 and Figure 3 As shown, the fixing mechanism 3 includes an electric push rod 31 and an arc-shaped lower pressure strip 32; a transverse plate 15 is provided on the side of the arc-shaped guide rail 1 close to the arc-shaped lower pressure plate 222, and the electric push rod 31 is provided on the transverse plate 15, and the actuator of the electric push rod 31 passes through the transverse plate 15 and is connected to the arc-shaped lower pressure strip 32.

[0041] By providing an electric push rod 31, the electric push rod 31 drives the arc bar to move, and the arc lower pressure bar 32 can contact the corresponding arc lower pressure plate 222, so that the corresponding arc lower pressure plate 222 moves toward the direction close to the arc guide rail 1, so that the arc lower pressure plate 222 fits the arc guide rail 1, and the position of the arc block 2 is preliminarily fixed. The two conductive columns 62 are moved to make the conductive columns 62 contact with the corresponding arc conductive sheet 14, so that the arc block 2 is fixed for a second time, thereby ensuring the stability of the arc block 2.

[0042] See also Figure 4 and Figure 5 As shown, an arc-shaped plate 16 is further provided in each arc-shaped through groove 11 , and a plurality of insertion holes 161 are equidistantly provided along the arc surface of the arc-shaped plate 16 , and a blocking disk 162 is hinged in each insertion hole 161 .

[0043] In order to prevent dust and mosquitoes from coming into contact with the arc-shaped conductive sheet 14 and causing power supply abnormality, an arc-shaped plate 16 is provided to block the arc-shaped through groove 11, and a plurality of insertion holes 161 are provided along the arc surface on the arc-shaped plate 16. A blocking disk 162 is hinged in each insertion hole 161 through a hinge. Under normal conditions, the blocking disk 162 is fitted with the arc-shaped plate 16 under the action of the hinge, thereby blocking the insertion hole 161; when the arc block 2 moves to the corresponding position, the two conductive columns 62 on the arc block 2 can contact the corresponding blocking disk 162, so that the blocking disk 162 rotates along the hinged position, and the conductive column 62 passes through the insertion hole 161 and contacts the arc-shaped conductive sheet 14 at the corresponding position, thereby realizing power supply.

[0044] See also Figure 3 and Figure 4 As shown, an arc-shaped orientation plate 17 is provided on the inner wall of the bottom of the arc-shaped guide rail 1 in a mirror image, and arc-shaped guide plates 171 for guiding the synchronous belt 52 are provided on the opposite sides of the two arc-shaped orientation plates 17 .

[0045] In order to ensure the movement accuracy of the arc block 2 and the rotation of the synchronous belt 52, the synchronous belt 52 is limited by two arc guide plates 171 so that when it is in the arc guide rail 1, it can only move between the two arc guide plates 171 and the two arc positioning plates. This not only ensures the tightness of the synchronous belt 52, but also ensures the accuracy of the moving position of the arc block 2.

[0046] See also Figure 2 、 Figures 6 to 9As shown, each lighting mechanism 4 includes a mounting base 41 and a lighting lamp 42; vertical plates 2211 are provided at both ends of the horizontal plate 221, the vertical plates 2211 and the horizontal plates 221 are perpendicular to each other, each vertical plate 2211 is provided with a rotating hole 2212, two hinge shafts 411 are provided on the mounting base 41, the hinge shafts 411 are rotatably set in the corresponding rotating holes 2212, the lighting lamp 42 is set on the mounting base 41, and a reset torsion spring 412 is provided on each hinge shaft 411; a sensor 2213 is provided on one of the vertical plates 2211, and a driving motor 2214 is provided on the other vertical plate 2211, a fan gear 2215 is provided on the motor shaft of the driving motor 2214, and a driving gear 413 is provided on the hinge shaft 411 close to the fan gear 2215, and the driving gear 413 is engaged with the fan gear 2215.

[0047] A cavity for the passage of a power line is provided in the sliding column 22. Similarly, a wire groove for the passage of a power line is also provided on the arc block 2, so that the conductive column 62 can be electrically connected to the mounting base 41 through a wire, and a sensor 2213 is provided to monitor whether a vehicle passes by. When no vehicle passes for a long time, the sensor data is within a certain fluctuation range, and the sensor dims the light of the lamp 42 through a processor (not shown in the figure), thereby saving energy; when a vehicle passes by, the sensor 2213 receives the data and processes the data through a corresponding processor (not shown in the figure), so that the lamp 42 becomes brighter and the drive motor 2214 rotates. The rotation of the driving motor 2214 can intermittently drive the driving gear 413 to rotate with the sector gear 2215, so that the lighting lamp 42 can rotate along the axis of the hinge shaft 411 and be reset under the torsion of the reset torsion spring 412; the lighting lamp 42 can be rotated to follow the direction of the vehicle's movement, which not only ensures that the vehicle is always illuminated during driving, thereby improving the safety of vehicle driving, but also reduces the number of lighting devices in the tunnel and reduces costs through the rotation of the lighting lamp 42; secondly, by arranging the surface lights on the inner walls of both sides of the tunnel, when the lighting lamp 42 on one side is reset, the lighting lamp 42 on the other side can be rotated repeatedly to avoid the formation of lighting blind spots.

[0048] See also Figure 2 As shown, arc-shaped fixing plates 18 are provided on the outer walls of both sides of the arc-shaped guide rail 1 , and a plurality of fixing holes 181 are provided on the arc-shaped fixing plates 18 .

[0049] The arc-shaped guide rail 1 is connected and fixed to the inner wall of the tunnel through the arc-shaped fixing plates 18 on both sides thereof by expansion bolts, which can ensure the connection stability of the arc-shaped guide rail 1.

[0050] See also Figure 2 As shown, a rotating motor 19 is provided on the arc guide rail 1 for driving the rotating shaft 51 to rotate.

[0051] By rotating the motor 19 to drive one of the rotating shafts 51 to rotate, the synchronous belt 52 between the two rotating shafts 51 can be rotated as the rotating shaft 51 rotates, thereby adjusting the position of the arc block 2 so that it can move to different heights to adapt to different tunnels.
