Description

Technical Field

[0001] This invention relates to the field of tunnel energy-saving lighting technology, and in particular to an energy-saving lighting device for tunnel dust reduction. Background Technology

[0002] Tunnel lighting plays a vital role in modern transportation networks. It is not only an essential infrastructure ensuring traffic safety but also fulfills the mission of energy conservation and environmental protection. LEDs, due to their high efficiency, energy saving, and long lifespan, have become the mainstream choice for tunnel lighting. LED luminaires can significantly reduce energy consumption, improve energy efficiency, and provide sufficient brightness to ensure traffic safety.

[0003] A search revealed that Chinese Patent CN216556883U discloses an energy-saving lighting device for highway tunnels, comprising a highway and a light-blocking device. A tunnel body is installed above the highway, and a tunnel is formed inside the tunnel body. Tunnel walls are installed on the surface of the tunnel, and adjustable lamps, speedometers, and lighting lamps are installed on the surface of the tunnel walls. A brightness sensor is installed on the surface of the tunnel body. The light-blocking device is installed inside the tunnel body, and a cylinder is installed inside the light-blocking device. A limit telescopic plate is installed on the right side of the cylinder, and a telescopic rod is installed on the surface of the limit telescopic plate. A baffle is connected to the surface of the telescopic rod, and a solar panel is installed on the surface of the baffle. A storage box is opened inside the tunnel body, and a battery is installed inside the storage box. This energy-saving lighting device for highway tunnels has adjustable brightness buffering and energy-saving lighting structure. However, in practical use, this solution still has the following shortcomings:

[0004] While the aforementioned tunnel lighting systems are designed and implemented to efficiently ensure brightness within the tunnel, guaranteeing visual clarity and safety during driving, in actual operation, airflow disturbances and tire-road friction generate fine particles that easily bring dust and impurities into the tunnel. This accumulation of dust and impurities not only reduces the effectiveness of the lighting systems, making the tunnel dim, but can also interfere with the driver's vision, increasing driving safety hazards. The dust problem is particularly prominent in tunnels with high traffic volume and speeds, and in severe cases, it can 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

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving lighting device for tunnel dust reduction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An energy-saving lighting device for dust suppression in tunnels includes a support pole and two mounting plates. The two mounting plates are symmetrically fixedly mounted on the support pole. A light box is symmetrically fixedly mounted on the outer wall of the support pole, and a light panel is provided on the inner wall of the light box. A ventilation cylinder is symmetrically fixedly mounted on the support pole. A rotating shaft is rotatably mounted on the inner wall of the ventilation cylinder. Several blades arranged in a circular array are fixedly mounted at both ends of the rotating shaft.

The inner wall of the slots is rotatably mounted with atomizing nozzles via a rotating rod. Both ends of the rotating rod are fitted with torsion springs. A connecting pipe is fixedly mounted on the top surface of the rotating seat. The outer wall of the connecting pipe is connected to the plurality of atomizing nozzles via conduits. A rotary joint is fixedly mounted on the top surface of the connecting pipe.

[0010] As a preferred embodiment of the present invention, a water supply pipe is provided at the top of the rotary joint, and the conduit is made of rigid plastic material.

[0011] As a preferred embodiment of the present invention, the linkage assembly includes a driven wheel disposed on the bottom end of the connecting plate and the rotating shaft, a shaft cylinder rotatably mounted on the side of the driven wheel located at the bottom end of the connecting plate, and a driving half-bevel gear fixedly mounted on the end of the shaft cylinder. The driven bevel gear is fixedly fitted on the outer wall of the connecting pipe, and the driven bevel gear meshes with the driving half-bevel gear. A synchronous belt is fitted on the outer wall of the two driven wheels, and a torsion spring is disposed between the fixed ring and the rotating seat.

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

[0013] As a preferred embodiment of the present invention, the cleaning assembly includes a reciprocating screw rotatably mounted on one end of the inner wall of the U-shaped groove, a guide rod rotatably mounted on the other end of the inner wall of the U-shaped groove, and guide rings fitted on the reciprocating screw and the guide rod. The inner wall of the U-shaped groove is symmetrically provided with guide grooves, and the inner wall of the U-shaped groove is symmetrically provided with connecting grooves communicating with the guide grooves. Spring telescopic rods are fixedly mounted on the outer walls of both guide rings. A connecting rod is fixedly mounted on the telescopic end of the spring telescopic rod, and the end of the connecting rod is slidably connected to the inner wall of the connecting groove. A support plate is fixedly mounted on the end of the connecting rod away from the connecting groove, and a cleaning roller is rotatably mounted between the opposite sides of the two support plates.

[0014] In a preferred embodiment of the present invention, the connecting groove is inclined, and the guide groove has the same width as the inner wall of the connecting groove.

[0015] As a preferred embodiment of the present invention, a pulley is rotatably fitted on the outer wall of the shaft cylinder, one end of the reciprocating screw passes through the side of the light box and is connected to the pulley via belt drive, and a limit structure is provided between the shaft cylinder and the pulley.

[0016] As a preferred embodiment of the present invention, the limiting structure includes an electric push rod fixedly installed on the inner wall of the shaft cylinder, a plurality of transmission rods arranged in a circular array and hinged to the telescopic end of the electric push rod, and a pin hinged to the end of the plurality of transmission rods away from the electric push rod, wherein the end of the pin away from the transmission rod passes through the shaft cylinder, and the inner wall of the pulley is provided with a plurality of pin grooves arranged in a circular array and adapted to the pins, and a plurality of guide sleeves corresponding to the pins are fixedly installed on the inner wall of the shaft cylinder.

[0017] As a preferred embodiment of the present invention, the inner wall of the pulley and the outer wall of the shaft cylinder are coated with lubricating oil.

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

[0019] 1. By setting up a linkage component and a dust suppression component, the rotation of the shaft and blades in the ventilation duct not only ensures the air circulation in the tunnel, but also uses the linkage component to drive the dust suppression component. The atomizing nozzles in the dust suppression component can rotate under different centrifugal forces to change their atomization range, thus achieving effective treatment of dust inside the tunnel. This design not only improves the dust suppression efficiency, but also ensures the wide range of dust suppression, effectively preventing dust from spreading in the tunnel and providing strong protection for driving safety in the tunnel.

[0020] 2. By setting up a light panel and a cleaning component, the cleaning component can clean the outer wall of the light panel at regular intervals. The cleaning roller can slide back and forth along the bottom surface of the light panel to effectively remove the dust attached to the light panel, ensuring sufficient light inside the tunnel. This cleaning function not only extends the service life of the light panel, but also improves the lighting quality of the tunnel, providing a more reliable guarantee for driving safety.

[0021] 3. By setting up a shaft cylinder and a limiting structure, and using the transmission rod and pin in cooperation, the device can flexibly switch transmission paths between different working states. When the electric push rod extends, the transmission rod pushes the pin into the pin groove, thereby establishing a connection between the shaft cylinder and the pulley, realizing the drive of the reciprocating screw. When the electric push rod retracts, the pin moves out of the pin groove, disengaging the connection between the shaft cylinder and the pulley, causing the reciprocating screw to stop rotating. This flexible transmission path switching mechanism provides strong support for dust suppression and cleaning functions. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figure 1-8 An energy-saving lighting device for dust suppression in tunnels includes a support rod 1 and two mounting plates 2. The two mounting plates 2 are symmetrically fixedly mounted on the support rod 1. A light box 3 is symmetrically fixedly mounted on the outer wall of the support rod 1. A light panel 4 is provided on the inner wall of the light box 3. A ventilation duct 5 is symmetrically fixedly mounted on the support rod 1. A rotating shaft 6 is rotatably mounted on the inner wall of the ventilation duct 5. Several blades 7 arranged in a ring array are fixedly mounted at both ends of the rotating shaft 6. A connecting plate 8 is fixedly mounted on the outer wall of the support rod 1 at the position between the ventilation duct 5 and the light box 3. A dust suppression component is provided at the bottom of the two connecting plates 8 for dust suppression in the tunnel. A linkage component is provided between the rotating shaft 6 and the dust suppression component for driving the dust suppression component. A U-shaped groove 12 is opened on the bottom surface of the light box 3 at the side position of the light panel 4. A cleaning component is provided inside the U-shaped groove 12 for cleaning the light panel 4.

[0033] In use, the support rod 1 can be installed in the tunnel through the mounting plate 2, and the light box 3 and the light panel 4 can be powered on. When the light panel 4 is lit, it can illuminate the interior of the tunnel to ensure the safety of vehicles 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 suppression component can be driven by the linkage component to treat the dust inside the tunnel and 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 at regular intervals so that the cleaning component can clean the outer wall of the light panel 4 regularly, preventing the dust on the light panel 4 from affecting the lighting brightness and ensuring sufficient light inside the tunnel. The working principle and connection method of the ventilation duct 5, the rotating shaft 6 and the blades 7 are all existing mature technologies and will not be described in detail here.

[0034] The dust suppression assembly includes a fixed ring 91 fixedly mounted on the bottom of the connecting plate 8 via a bracket, a rotating seat 92 rotatably mounted on the inner wall of the fixed ring 91, and several slots 93 arranged in a ring array on the outer wall of the rotating seat 92. The inner wall of the slots 93 is rotatably mounted with atomizing nozzles 94 via a rotating rod. Both ends of the rotating rod are fitted with torsion springs 95. A connecting pipe 96 is fixedly mounted on the top surface of the rotating seat 92. The outer wall of the connecting pipe 96 is connected to the several atomizing nozzles 94 via conduits 97. The conduits 97 are made of rigid plastic material. A rotary joint 98 is fixedly mounted on the top surface of the connecting pipe 96. A water supply pipe 10 is provided at the top of the rotary joint 98.

[0035] Under the action of the linkage component, the rotating seat 92 can be driven to reciprocate along the fixed ring 91 through the connecting pipe 96. During the reciprocating rotation of the rotating seat 92, due to the different rotation speeds, the atomizing nozzle 94 in the slot 93 can rotate and change its atomization range under the action of different centrifugal forces. Furthermore, under the use of the torsion spring 95, when the centrifugal force decreases, the atomizing nozzle 94 can rotate in the reset direction, thereby achieving dust suppression in different ranges. Before use, water can be supplied through the water supply pipe 10. 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, thereby achieving effective dust suppression in the tunnel.

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

[0037] In 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 via the synchronous belt 115. When the driven wheel 111 rotates, it can synchronously drive the shaft cylinder 112 and the driving half bevel gear 113 to rotate. The driving half bevel gear 113 meshes with the driven bevel gear 114. When the teeth on the driving half bevel gear 113 mesh with the driven bevel gear 114, it can drive the driven bevel gear 114 to rotate. When the teeth on the driving half bevel gear 113 separate from the teeth on the driven bevel gear 114, the driven bevel gear 114 can reverse under the action of the torsion spring 116. This reciprocating motion can realize the reciprocating drive 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 reciprocate along the fixed ring 91 via the connecting pipe 96.

[0038] The cleaning assembly includes a reciprocating screw 131 rotatably mounted on one end of the inner wall of the U-shaped groove 12, a guide rod 132 rotatably mounted on the other end of the inner wall of the U-shaped groove 12, and a guide ring 133 fitted on the reciprocating screw 131 and the guide rod 132. The inner wall of the U-shaped groove 12 is symmetrically provided with guide grooves 134 and connecting grooves 135 communicating with the guide grooves 134. 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 installed on the outer walls of the two guide rings 133. A connecting rod 137 is fixedly installed on 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 installed on the end of the connecting rod 137 away from the connecting groove 135. A cleaning roller 139 is rotatably mounted between the opposite sides of the two support plates 138.

[0039] When the reciprocating screw 131 rotates, the guide ring 133 is screwed to the reciprocating screw 131, and the connecting rod 137 on the support plates 138 at both ends of the cleaning roller 139 is slidably connected to the connecting groove 135 and the guide groove 134. Therefore, when the reciprocating screw 131 rotates, it can drive the guide ring 133 to slide along the guide rod 132. During the sliding process of the guide 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 guide groove 134. This allows the cleaning roller 139 to slide back and forth along the U-shaped groove 12 to fit against the bottom surface of the lamp panel 4. As the reciprocating screw 131 continues to rotate, the cleaning roller 139 can slide back and forth 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 re-enter the connecting groove 135, and the cleaning roller 139 returns to the U-shaped groove 12, thus realizing the storage of the cleaning roller 139 and preventing the cleaning roller 139 from being exposed and affecting the lighting range of the lamp panel 4.

[0040] A pulley 14 is rotatably mounted on the outer wall of the shaft cylinder 112. Lubricating oil is applied between the inner wall of the pulley 14 and the outer wall of the shaft cylinder 112. One end of the reciprocating screw 131 passes through the side of the light box 3 and is connected to the pulley 14 via belt drive. A limiting structure is provided 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 arranged in a ring array and hinged to the telescopic end of the electric push rod 151, and a pin 153 hinged to the end of the several transmission rods 152 away from the electric push rod 151. The end of the pin 153 away from the transmission rod 152 passes through the shaft cylinder 112. Several pin grooves 154 arranged in a ring array and adapted to the pin 153 are opened on the inner wall of the pulley 14. Several guide sleeves 155 corresponding to the pin 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 extend at regular intervals. 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 153, so that the pin 153 slides along the guide sleeve 155 into the pin groove 154 on the inner wall of the pulley 14. This allows the shaft cylinder 112 to rotate, which in turn drives the pulley 14 to rotate, and through the belt, drives the reciprocating screw 131 to rotate. When the reciprocating screw 131 does not need to be driven, the electric push rod 151 can shorten, causing the pin 153 to move out of the pin groove 154, disconnecting the connection between the shaft cylinder 112 and the pulley 14, and stopping the reciprocating screw 131 from rotating.

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

[0043] In use, the support rod 1 can be installed in the tunnel through the mounting plate 2, and the light box 3 and the light panel 4 can be powered on. When the light panel 4 is lit, it can illuminate the interior of the tunnel to ensure the safety of vehicles 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 suppression component can be driven by the linkage component to treat the dust inside the tunnel and 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 at regular intervals so that the cleaning component can clean the outer wall of the light panel 4 regularly, preventing the dust on the light panel 4 from affecting the lighting brightness and ensuring sufficient light inside the tunnel. The working principle and connection method of the ventilation duct 5, the rotating shaft 6 and the blades 7 are all existing mature technologies and will not be described in detail here.

[0044] In daily use, when the rotating shaft 6 rotates, it drives the driven wheel 111 at the bottom of the connecting plate 8 to rotate via the synchronous belt 115. The rotation of the driven wheel 111 synchronously drives the shaft cylinder 112 and the driving half-bevel gear 113 to rotate. The driving half-bevel gear 113 meshes with the driven bevel gear 114, thus driving the driven bevel gear 114 to rotate. When the teeth on the driving half-bevel gear 113 disengage from the teeth on the driven bevel gear 114, the driven bevel gear 114 can reverse direction under the action of the torsion spring 116. This reciprocating motion achieves the reciprocating drive rotation of the driven bevel gear 114. During the reciprocating rotation of the bevel gear 114, the rotating seat 92 can be driven to reciprocate along the fixed ring 91 via the connecting pipe 96. During the reciprocating rotation of the rotating seat 92, due to the different rotation speeds, the atomizing nozzle 94 in the slot 93 can rotate and change its atomization range under the action of different centrifugal forces. Furthermore, under the use of the torsion spring 95, when the centrifugal force decreases, the atomizing nozzle 94 can rotate in the reset direction, thereby achieving dust suppression in different ranges. Before use, water can be supplied through the water supply pipe 10. 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, thereby achieving effective dust suppression in the tunnel.

[0045] During the rotation of the shaft cylinder 112, the electric push rod 151 can extend at regular intervals. During this extension, the electric push rod 151 drives the transmission rod 152 to rotate. When the transmission rod 152 rotates, it pushes the pin 153, causing the pin 153 to slide along the guide sleeve 155 into the pin groove 154 on the inner wall of the pulley 14. This allows the shaft cylinder 112 to rotate, driving the pulley 14 to rotate, which in turn drives the reciprocating screw 131 to rotate via the belt. When the reciprocating screw 131 rotates, the guide ring 133 is screwed to the reciprocating screw 131, and the connecting rod 137 on the support plates 138 at both ends of the cleaning roller 139 is slidably connected to the connecting groove 135 and the guide groove 134. Therefore, when the reciprocating screw 131 rotates, it drives the guide ring 133 to slide along the guide rod 132. During the sliding of the guide ring 133, it can be extended by a spring. The retracting rod 136 drives the connecting rod 137. 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 U-shaped groove 12 and fits against the bottom surface of the lamp plate 4. As the reciprocating screw 131 continues to rotate, the cleaning roller 139 can slide back and forth along the bottom surface of the lamp plate 4 to clean the bottom surface of the lamp plate 4. When the cleaning roller 139 moves back, the connecting rod 137 can re-enter the connecting groove 135. At this time, the cleaning roller 139 returns to the U-shaped groove 12, realizing the storage of the cleaning roller 139 and preventing the cleaning roller 139 from being exposed and affecting the lighting range of the lamp plate 4. At this time, the electric push rod 151 shortens, causing the pin 153 to move out of the pin groove 154, releasing the connection between the shaft cylinder 112 and the pulley 14, and the reciprocating screw 131 can stop rotating.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
