Description

Technical Field

[0001] The present invention relates to the technical field of tunnel energy-saving lighting, and particularly relates to an energy-saving lighting device for tunnel dust reduction. Background Art

[0002] Tunnel lighting plays a crucial role in the modern transportation network. It is not only an infrastructure for ensuring driving safety but also undertakes the mission of energy conservation and environmental protection. Due to its advantages such as high efficiency, energy saving, and long lifespan, LEDs have become the mainstream choice for tunnel lighting. LED lamps can significantly reduce energy consumption, improve energy utilization efficiency, and at the same time provide sufficient brightness to ensure driving safety.

[0003] After retrieval, a Chinese patent with the publication number CN216556883U discloses a highway tunnel energy-saving lighting device, including a highway and a light-blocking device. Above the highway, a tunnel body is installed, and inside the tunnel body, there is a tunnel. And on the surface of the tunnel, there is a tunnel wall. On the surface of the tunnel wall, there are adjustable lamp tubes, and a speed detector is installed on the surface of the tunnel wall, and a lighting lamp is installed on the surface of the tunnel wall. On the surface of the tunnel body, there is a brightness sensor. The light-blocking device is installed inside the tunnel body, and inside the light-blocking device, there is a cylinder, and a limit telescopic plate is installed on the right side of the cylinder. On the surface of the limit telescopic plate, there is a telescopic rod, and on the surface of the telescopic rod, there is a baffle plate, and on the surface of the baffle plate, there is a solar panel. Inside the tunnel body, there is a placement box, and a storage battery is installed inside the placement box. This highway tunnel energy-saving lighting device has a brightness adjustment buffer and an energy-saving lighting structure. However, when this solution is actually used, there are still the following deficiencies:

[0004] Although the above-mentioned tunnel lighting device can efficiently ensure the lighting brightness inside the tunnel in terms of design and application, and ensure visual clarity and safety during driving, during actual operation, when vehicles pass through the tunnel normally, due to the air flow disturbance generated by vehicle driving and the tiny particles generated by the friction between the tires and the road surface, external dust and impurities are easily brought into the tunnel interior. These dust and impurities accumulate inside the tunnel, which not only reduces the lighting effect of the lighting device, making the light inside the tunnel become blurred, but may also interfere with the driver's line of sight, increasing potential safety hazards during driving. Especially in some tunnels with large traffic flow and high vehicle speed, the dust problem is particularly prominent, and in severe cases, it may even lead to traffic accidents.

[0005] Therefore, it is necessary to design an energy-saving lighting device for tunnel dust reduction to solve the above problems. Summary of the Invention

[0012] As a preferred technical solution of the present invention, the number of teeth of the driving semi-conical gear is at least greater than half of the number of teeth of the driven bevel gear.

[0013] As a preferred technical solution of the present invention, the cleaning component includes a reciprocating lead screw rotatably installed at one end of the inner wall of the U-shaped groove, a guide rod rotatably installed at the other end of the inner wall of the U-shaped groove, and a guide ring sleeved on the reciprocating lead screw and the guide rod. Guide grooves are symmetrically formed on the inner wall of the U-shaped groove, and connection grooves communicating with the guide grooves are symmetrically formed on the inner wall of the U-shaped groove. Spring telescopic rods are fixedly installed on the outer walls of the two guide rings.

[0018] The present invention has the following beneficial effects:

[0019] 1. By setting the linkage component and the dust reduction component, the rotation of the rotating shaft and the blades in the ventilation tube not only ensures the gas circulation in the tunnel, but also uses the linkage component to drive the dust reduction component. The atomizing nozzles in the dust reduction component can rotate under the action of different centrifugal forces to change their atomizing ranges, realizing the effective treatment of the dust inside the tunnel. This design not only improves the dust reduction efficiency, but also ensures the wide range of the dust reduction area, effectively avoiding the dispersion of dust in the tunnel and providing a strong guarantee for the driving safety in the tunnel;

[0020] 2. By setting up the lamp board and the cleaning component, the cleaning component can regularly clean the outer wall of the lamp board. The cleaning roller can reciprocally slide along the bottom surface of the lamp board, effectively removing the dust attached to the lamp board, ensuring sufficient brightness inside the tunnel. This cleaning function not only extends the service life of the lamp board but also improves the lighting quality of the tunnel, providing a more reliable guarantee for driving safety.

[0021] 3. By setting up the shaft cylinder and the limiting structure, and through the combined use of the transmission rod and the pin rod, the device can flexibly switch the transmission path between different working states. When the electric push rod extends, the transmission rod pushes the pin rod into the pin slot, thus establishing the connection between the shaft cylinder and the pulley, realizing the drive of the reciprocating lead screw. When the electric push rod shortens, the pin rod moves out of the pin slot, releasing the connection between the shaft cylinder and the pulley, causing the reciprocating lead screw to stop rotating. This flexible transmission path switching mechanism provides strong support for the dust reduction and cleaning functions. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Refer to Figure 1-8 , an energy-saving lighting device for tunnel dust reduction, including a support rod 1 and two mounting plates 2. The two mounting plates 2 are symmetrically and fixedly installed on the support rod 1. The outer wall of the support rod 1 is symmetrically and fixedly installed with light boxes 3. The inner wall of the light box 3 is provided with a light board 4. The support rod 1 is symmetrically and fixedly installed with ventilation ducts 5. The inner wall of the ventilation duct 5 is rotatably installed with a rotating shaft 6. Both ends of the rotating shaft 6 are fixedly installed with a plurality of blades 7 distributed in an annular array. The outer wall of the support rod 1 is fixedly installed with connecting plates 8 at the positions between the ventilation ducts 5 and the light boxes 3. Dust reduction components are provided at the bottom ends of the two connecting plates 8 for dust reduction in the tunnel. A linkage component is provided between the rotating shaft 6 and the dust reduction component for driving the dust reduction component. A square groove 12 is opened at the bottom surface of the light box 3 at the side position of the light board 4. A cleaning component is provided inside the square groove 12 for cleaning the light board 4.

[0033] During use, the support rod 1 can be installed in the tunnel through the mounting plate 2, and the light box 3 and the light board 4 are powered on. When the light board 4 is lit, it can illuminate the interior of the tunnel to ensure driving safety in the tunnel. During daily use, the rotating shaft 6 and the blades 7 in the ventilation duct 5 can rotate to ensure air circulation in the tunnel. During the rotation of the rotating shaft 6, the dust reduction component can be driven through the linkage component, so that the dust reduction component can process the dust inside the tunnel to prevent the dust from spreading in the tunnel. At the same time, through the use of the limit structure, the linkage component can drive the cleaning component regularly, so that the cleaning component can regularly clean the outer wall of the light board 4, preventing dust from adhering to the light board 4 and affecting the lighting brightness, and ensuring sufficient light inside the tunnel. The working principles and connection methods of the ventilation duct 5, the rotating shaft 6 and the blades 7 are all existing mature technologies and will not be elaborated here.

[0034] The dust reduction component includes a fixed ring 91 fixedly installed at the bottom end of the connecting plate 8 through a bracket, a rotating seat 92 rotatably installed on the inner wall of the fixed ring 91, and a plurality of slots 93 arranged in a circular array on the outer wall of the rotating seat 92. The inner wall of the slot 93 is rotatably installed with an atomizing nozzle 94 through a rotating rod. Torsion springs 95 are sleeved at both ends of the rotating rod. A connecting pipe 96 is fixedly installed on the top surface of the rotating seat 92. The outer wall of the connecting pipe 96 is communicated with a plurality of atomizing nozzles 94 through a conduit 97. The conduit 97 is made of rigid plastic material. A rotary joint 98 is fixedly installed on the top surface of the connecting pipe 96. A water supply pipe 10 is arranged at the top end of the rotary joint 98.

[0035] Under the action of the linkage component, the rotating seat 92 can be driven to rotate reciprocally along the fixed ring 91 through the connecting pipe 96. During the reciprocating rotation of the rotating seat 92, due to different rotation speeds, the atomizing nozzles 94 in the slots 93 can rotate to change their atomizing ranges under the action of different centrifugal forces. And with the use of the torsion spring 95, when the centrifugal force decreases, the atomizing nozzle 94 can rotate in the reset direction, thus realizing dust reduction in different ranges. Before use, water can be supplied through the water supply pipe 10. The water can enter the atomizing nozzle 94 through the water supply pipe 10, the rotary joint 98, the connecting pipe 96 and the conduit 97 for use, thus realizing effective dust reduction in the tunnel.

[0036] The linkage assembly includes a driven wheel 111 arranged at the bottom end of the connecting plate 8 and on the rotating shaft 6, a shaft cylinder 112 rotatably mounted on the side of the driven wheel 111 at the bottom end of the connecting plate 8, and a driving semi-conical gear 113 fixedly mounted at the end of the shaft cylinder 112. A driven bevel gear 114 is fixedly sleeved on the outer wall of the connecting pipe 96, and the driven bevel gear 114 meshes with the driving semi-conical gear 113. The number of teeth of the driving semi-conical gear 113 is at least greater than half of the number of teeth of the driven bevel gear 114. A synchronous belt 115 is sleeved on the outer walls of the two driven wheels 111. A second torsion spring 116 is arranged between the fixed ring 91 and the rotating seat 92.

[0037] During daily use, when the rotating shaft 6 rotates, it can drive the driven wheel 111 at the bottom end of the connecting plate 8 to rotate through the synchronous belt 115. When the driven wheel 111 rotates, it can synchronously drive the shaft cylinder 112 and the driving semi-conical gear 113 to rotate. The driving semi-conical gear 113 meshes with the driven bevel gear 114. Therefore, when the teeth of the driving semi-conical gear 113 mesh with the teeth of the driven bevel gear 114, it can drive the driven bevel gear 114 to rotate. When the teeth of the driving semi-conical gear 113 are separated from the teeth of the driven bevel gear 114, at this time, under the action of the second torsion spring 116, the driven bevel gear 114 can rotate in the reverse direction. By repeating this process, the reciprocating driving rotation of the driven bevel gear 114 can be realized. During the reciprocating rotation of the driven bevel gear 114, it can drive the rotating seat 92 to rotate reciprocally along the fixed ring 91 through the connecting pipe 96.

[0038] The cleaning assembly includes a reciprocating lead screw 131 rotatably mounted at one end of the inner wall of the U-shaped groove 12, a guide rod 132 rotatably mounted at the other end of the inner wall of the U-shaped groove 12, and a guide ring 133 sleeved on the reciprocating lead screw 131 and the guide rod 132. Guide grooves 134 are symmetrically formed on the inner wall of the U-shaped groove 12. Connecting grooves 135 communicating with the guide grooves 134 are symmetrically formed on the inner wall of the U-shaped groove 12. The connecting grooves 135 are inclined. The inner wall widths of the guide grooves 134 and the connecting grooves 135 are the same. Spring telescopic rods 136 are fixedly mounted on the outer walls of the two guide rings 133. A connecting rod 137 is fixedly mounted at the telescopic end of the spring telescopic rod 136, and the end of the connecting rod 137 is slidably connected to the inner wall of the connecting groove 135. A support plate 138 is fixedly mounted at the end of the connecting rod 137 away from the connecting groove 135. A cleaning roller 139 is rotatably mounted between the opposite side surfaces of the two support plates 138.

[0039] When the reciprocating lead screw 131 rotates, since the guiding ring 133 is screwed to the reciprocating lead screw 131, the connecting rods 137 on the two end support plates 138 of the cleaning roller 139 are slidably connected to the connecting grooves 135 and the guiding grooves 134. Therefore, when the reciprocating lead screw 131 rotates, it can drive the guiding ring 133 to slide along the guide rod 132. During the sliding process of the guiding ring 133, the connecting rod 137 can be driven by the spring telescopic rod 136. In the initial state, the connecting rod 137 can slide along the connecting groove 135 into the guiding groove 134, so that the cleaning roller 139 slides out of the square-shaped groove 12 and fits against the bottom surface of the lamp panel 4. As the reciprocating lead screw 131 continues to rotate, the cleaning roller 139 can reciprocally slide along the bottom surface of the lamp panel 4 to clean the bottom surface of the lamp panel 4. When the cleaning roller 139 moves back, the connecting rod 137 can enter the connecting groove 135 again. At this time, the cleaning roller 139 returns to the square-shaped groove 12 again, realizing the storage of the cleaning roller 139 and avoiding the exposure of the cleaning roller 139 from affecting the illumination range of the lamp panel 4.

[0040] A pulley 14 is rotatably sleeved on the outer wall of the shaft cylinder 112. Lubricating oil is coated between the inner wall of the pulley 14 and the outer wall of the shaft cylinder 112. One end of the reciprocating lead screw 131 passes through the side surface of the lamp box 3 and is connected to the pulley 14 through a belt drive. A limiting structure is arranged between the shaft cylinder 112 and the pulley 14. The limiting structure includes an electric push rod 151 fixedly installed on the inner wall of the shaft cylinder 112, several transmission rods 152 hinged to the telescopic end of the electric push rod 151 and distributed in a circular array, and a pin rod 153 hinged to one end of several transmission rods 152 far away from the electric push rod 151. And one end of the pin rod 153 far away from the transmission rod 152 is arranged through the shaft cylinder 112. A plurality of pin grooves 154 adapted to the pin rod 153 are arranged in a circular array on the inner wall of the pulley 14. A plurality of guiding sleeves 155 corresponding to the pin rod 153 are fixedly installed on the inner wall of the shaft cylinder 112.

[0041] During the rotation of the shaft cylinder 112, the electric push rod 151 can be extended regularly. During the extension process of the electric push rod 151, it can drive the transmission rod 152 to rotate. When the transmission rod 152 rotates, it can push the pin rod 153, so that the pin rod 153 slides along the guiding sleeve 155 and enters the pin groove 154 on the inner wall of the pulley 14, so that when the shaft cylinder 112 rotates, it can drive the pulley 14 to rotate, and drive the reciprocating lead screw 131 to rotate through the belt. When the reciprocating lead screw 131 does not need to be driven, the electric push rod 151 can be shortened so that the pin rod 153 moves out of the pin groove 154, releasing the connection between the shaft cylinder 112 and the pulley 14, and the reciprocating lead screw 131 can stop rotating.

[0042] The specific working principle of the present invention is as follows:

[0043] During use, the support rod 1 can be installed in the tunnel through the mounting plate 2, and the light box 3 and the light board 4 are powered on. When the light board 4 is lit, it can illuminate the interior of the tunnel to ensure driving safety in the tunnel. During daily use, the rotating shaft 6 and the blades 7 in the ventilation duct 5 can rotate to ensure the air circulation in the tunnel. During the rotation of the rotating shaft 6, the dust reduction component can be driven through the linkage component, so that the dust reduction component can handle the dust inside the tunnel to prevent the dust from spreading in the tunnel. At the same time, through the use of the limiting structure, the linkage component can drive the cleaning component regularly, so that the cleaning component can regularly clean the outer wall of the light board 4, preventing dust from adhering to the light board 4 and affecting the lighting brightness, and ensuring sufficient light inside the tunnel. The working principles and connection methods of the ventilation duct 5, the rotating shaft 6 and the blades 7 are all existing mature technologies and will not be elaborated here.

[0044] During daily use, when the rotating shaft 6 rotates, it can drive the driven wheel 111 at the bottom of the connecting plate 8 to rotate through the synchronous belt 115. When the driven wheel 111 rotates, it can drive the shaft cylinder 112 and the driving bevel gear 113 to rotate synchronously. The driving bevel gear 113 meshes with the driven bevel gear 114. Therefore, when the teeth on the driving bevel gear 113 mesh with the teeth on the driven bevel gear 114, the driven bevel gear 114 can be driven to rotate. When the teeth on the driving bevel gear 113 are separated from the teeth on the driven bevel gear 114, at this time, under the action of the torsion spring two 116, the driven bevel gear 114 can rotate in the reverse direction, and this reciprocating motion can realize the reciprocating driving rotation of the driven bevel gear 114; during the reciprocating rotation of the driven bevel gear 114, the rotating seat 92 can be driven to rotate reciprocally along the fixed ring 91 through the connecting pipe 96. During the reciprocating rotation of the rotating seat 92, due to its different rotation speeds, under the action of different centrifugal forces, the atomizing nozzles 94 in the slots 93 can rotate to change their atomizing ranges. And under the use of the torsion spring one 95, when the centrifugal force decreases, the atomizing nozzles 94 can rotate in the reset direction, thus realizing dust reduction in different ranges. Before use, water can be supplied through the water supply pipe 10. The water can enter the atomizing nozzles 94 through the water supply pipe 10, the rotary joint 98, the connecting pipe 96 and the conduit 97 for use, thus realizing effective dust reduction in the tunnel.

[0045] During the rotation of the shaft cylinder 112, the electric push rod 151 can be extended regularly. During the extension of the electric push rod 151, it can drive the transmission rod 152 to rotate. When the transmission rod 152 rotates, it can push the pin rod 153, so that the pin rod 153 slides along the guide sleeve 155 and enters the pin slot 154 on the inner wall of the pulley 14, so that when the shaft cylinder 112 rotates, it can drive the pulley 14 to rotate, and drive the reciprocating lead screw 131 to rotate through the belt. When the reciprocating lead screw 131 rotates, since the guide ring 133 is screwed with the reciprocating lead screw 131, and the connecting rod 137 on the two end support plates 138 of the cleaning roller 139 is slidably connected with the connecting groove 135 and the guide groove 134, the reciprocating lead screw 131 can drive the guide ring 133 to slide along the guide rod 132 when it rotates. During the sliding of the guide ring 133, it can drive the connecting rod 137 through the spring telescopic rod 136. In the initial state, the connecting rod 137 can slide along the connecting groove 135 into the guide groove 134, so that the cleaning roller 139 slides out of the mouth-shaped groove 12 and fits against the bottom surface of the lamp board 4. As the reciprocating lead screw 131 continues to rotate, the cleaning roller 139 can reciprocally slide along the bottom surface of the lamp board 4 to clean the bottom surface of the lamp board 4. When the cleaning roller 139 moves back, the connecting rod 137 can enter the connecting groove 135 again. At this time, the cleaning roller 139 returns to the mouth-shaped groove 12 again, realizing the storage of the cleaning roller 139, avoiding the cleaning roller 139 being exposed and affecting the illumination range of the lamp board 4. And at this time, the electric push rod 151 shortens, so that the pin rod 153 moves out of the pin slot 154, releasing the connection between the shaft cylinder 112 and the pulley 14, and the reciprocating lead screw 131 can stop rotating.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
