Description

Technical Field

[0001] This invention relates to the field of energy-saving lighting devices, specifically to a self-cleaning tunnel light and its usage method. Background Technology

[0002] With the rapid development of new lighting technologies, tunnel lights, as key energy-saving lighting equipment, widely adopt high-efficiency light sources such as LEDs to mitigate the abrupt changes in light intensity (such as the "black hole effect" or "white hole effect") when vehicles enter and exit tunnels, ensuring driving safety and reducing energy consumption. However, in practical applications, tunnel lights are exposed to dust, vehicle exhaust, and humid environments for extended periods, causing dust accumulation on the light-emitting surface and heat dissipation fins. This severely affects lighting brightness and heat dissipation performance, thereby increasing energy consumption and shortening the lifespan of the lamps. Traditional cleaning relies on manual labor, which is inefficient, costly, and poses significant safety risks. Especially in high-density traffic tunnels, cleaning operations can easily interrupt lighting or cause accidents, further amplifying the problem of energy waste.

[0003] Existing technologies include patents exploring self-cleaning mechanisms for tunnel lights. For example, Chinese patent CN110095564 B discloses a self-cleaning tunnel light, which includes a tunnel light mounted on the tunnel wall, a transparent cover, a guide rail, a mounting bracket, and a cleaning component (such as a brush) that can slide along the guide rail. This patent achieves automatic cleaning of the light fixture surface by the brush through electric drive and incorporates rotation and sliding mechanisms on the cleaning component to adapt to cleaning needs at different locations. However, this technology has the following drawbacks: cleaning mainly relies on a single mechanical brush, which cannot effectively combine airflow to remove stubborn dust accumulated between the heat sink fins, resulting in incomplete cleaning and limited restoration of lighting efficiency.

[0024] The moving mechanism 3 includes a traveling wheel 304, a bracket 305, a track 306, a limiting plate 307, and a back plate 308; the back plate 308 is fixedly connected to the track 306, and both the track 306 and the limiting plate 307 are fixedly mounted on the back plate 308; the traveling wheel 304 is rotatably mounted on the track 306 for moving along the track 306; the bracket 305 is rotatably connected to the traveling wheel 304 and slidably connected to the limiting plate 307 to limit the movement path of the bracket 305 and prevent derailment; the cleaning mechanism 6 is mounted on the bracket 305 and moves with the bracket 305.

[0025] Furthermore, there are two of each of the following: the walking wheel 304, the bracket 305, the track 306, and the limiting plate 307. The two walking wheels 304, the two brackets 305, the two tracks 306, and the two limiting plates 307 are symmetrically arranged on opposite sides of the cleaning mechanism 6 and distributed in a direction perpendicular to the direction of movement to ensure the stability and balance of the moving mechanism 3.

[0026] Each lamp body 2 is equipped with two corresponding tracks 306, two limiting plates 307, and a back plate 308. Multiple sets of lamp bodies 2 are arranged sequentially along the extension direction of the tunnel, so that the ends of multiple tracks 306 in multiple sets of moving mechanisms 3 are connected to each other, and the ends of multiple limiting plates 307 are connected to each other, so that the walking wheels 304 can continuously walk on multiple tracks 306, and realize the continuous cleaning of multiple sets of lamp bodies 2 by the cleaning mechanism 6.

[0027] The cleaning mechanism 6 includes a main shaft 601 and a cleaning brush 602; the two ends of the main shaft 601 are rotatably connected to two brackets 305 respectively, and the cleaning brush 602 is fixedly connected to the outer wall of the main shaft 601 for cleaning the light-emitting surface of the lamp body 2 when rotating.

[0028] The moving mechanism 3 also includes a motor 301 and a base plate 302; the base plate 302 is fixedly connected to the support 305 located below, the base plate 302 is fixedly connected to the motor 301, and the output end of the motor 301 is fixedly connected to the walking wheel 304 located below, for driving the walking wheel 304 to rotate, thereby driving the support 305 and the cleaning mechanism 6 to move along the track 306.

[0029] The moving mechanism 3 also includes a first synchronous pulley 303 and a second synchronous pulley 309; the first synchronous pulley 303 is coaxially and fixedly connected to the output end of the motor 301, the first synchronous pulley 303 is connected to the second synchronous pulley 309 through a synchronous belt, and the second synchronous pulley 309 is coaxially and fixedly connected to the main shaft 601 of the cleaning mechanism 6, so that the output power of the motor 301 can be synchronously transmitted to the main shaft 601, so that the cleaning brush 602 rotates to clean during the movement.

[0030] In actual use, after the motor 301 starts, it drives the walking wheel 304 to move along the track 306 through the transmission of the first synchronous wheel 303 and the second synchronous wheel 309. At the same time, it drives the cleaning brush 602 to rotate and self-clean the light-emitting surface of the lamp body 2. Since the tracks 306 and the limit plate 307 of multiple lamp bodies 2 are connected, the cleaning mechanism 6 can continuously pass through multiple sets of lamp bodies 2 to realize the automatic cleaning of the entire tunnel light system, improve maintenance efficiency and extend the service life of the lamp body.

[0031] In this embodiment, a flushing assembly 7 is also included. The flushing assembly 7 is disposed on the cleaning mechanism 6 and is used to spray airflow onto the heat dissipation fins 8 to assist in cleaning the heat dissipation structure of the lamp body 2. The flushing assembly 7 includes a main pipe 701 and multiple nozzles 702. The main pipe 701 is a hollow tube, and the multiple nozzles 702 are evenly distributed and fixedly connected to the outer wall of the main pipe 701 and communicate with the interior of the main pipe 701 for spraying airflow. The direction in which the heat dissipation fins 8 are arranged on the lamp body 2 is parallel to and corresponds one-to-one with the spraying direction of the multiple nozzles 702 to ensure that the airflow directly flushes the gaps between the heat dissipation fins 8 and removes accumulated dust.

[0032] The flushing assembly 7 also includes a connector 704, which is fixedly connected to one end of the main pipe 701 and communicates with the interior of the main pipe 701 for connecting to an external air source.

[0033] It also includes an air supply assembly 5; the air supply assembly 5 is mounted on the moving mechanism 3 and connected to the flushing assembly 7, for generating and supplying compressed airflow to the flushing assembly 7; the air supply assembly 5 includes a mounting plate 501, two air cylinders 502, two pistons 503, two screws 504, two sleeves 505, two first one-way valves 506, two second one-way valves 507, two first pipe bodies 508, two first shaft bodies 509, a second shaft body 512, two first gears 510 and a second gear 511.

[0034] The mounting plate 501 is fixedly connected to the bracket 305 to support other components of the air supply assembly 5. The mounting plate 501 is fixedly connected to the two air cylinders 502, which are hollow cylinders used to contain gas and generate compressed airflow. The two pistons 503 are slidably disposed within the two air cylinders 502, and their initial positions are offset to achieve alternating gas compression. The two pistons 503 are fixedly connected to one end of the two sleeves 505. The inner walls of the two sleeves 505 are provided with internal threads, which mesh with the external threads of the two screws 504 to convert rotational motion into linear motion. The outer walls of the two screws 504 are provided with external threads, one of which is a right-hand thread and the other is a left-hand thread, so that when the two screws 504 rotate in the same direction, the two sleeves... 505 drives the two pistons 503 to move linearly in opposite directions, realizing the alternating compression and intake of gas in the two air cylinders 502; the other ends of the two screws 504 are respectively coaxially and fixedly connected to one end of the two first shafts 509; the first gears 510 are respectively fixedly connected to the outer walls of the two first shafts 509; the two first gears 510 are both meshed with the second gears 511 for transmitting power, wherein when the second gear 511 is driven to rotate clockwise by the motor 301, the two first gears 510 rotate counterclockwise, thereby ensuring that the two screws 504 rotate in the same direction; the second gear 511 is coaxially and fixedly connected to the second shaft 512; the two first shafts 509 and the second shaft 512 are both rotatably connected to the mounting plate 501 to achieve smooth rotation; the other end of the second shaft 512 is coaxially and fixedly connected to the second synchronous pulley 309, thereby receiving power from the motor 301.

[0035] The outlet end of each air cylinder 502 is fixedly connected to one end of the corresponding first tube 508 and communicates with it. The other end of the first tube 508 is fixedly connected to the connector 704 through the second one-way valve 507 and communicates with it. The inlet end of each air cylinder 502 is provided with a first one-way valve 506, which allows external air to enter the air cylinder 502 in one direction. The second one-way valve 507 only allows air to flow from the air cylinder 502 to the connector 704.

[0036] In actual use, after the motor 301 starts, through the transmission of the first synchronous pulley 303, the synchronous belt, and the second synchronous pulley 309, it not only drives the traveling wheel 304 to move along the track 306 and drives the cleaning brush 602 to rotate and clean the light-emitting surface of the lamp body 2, but also synchronously drives the second shaft 512 to rotate; the second shaft 512 drives the two first gears 510 to rotate through the second gear 511, thereby driving the two screws 504 to rotate; the two screws 504 respectively push the two pistons 503 through the two sleeves 505 to rotate in the two air cylinders 50 The internal reciprocating linear movement of the piston 503, due to the staggered arrangement of the two pistons 503, achieves alternating compression of gas. During the intake stroke, the piston 503 draws in external air through the first one-way valve 506. During the compression stroke, the compressed gas is delivered to the main pipe 701 through the second one-way valve 507 and the first pipe 508. Finally, the airflow is sprayed out by multiple nozzles 702 to flush and clean the heat dissipation fins 8, thereby enhancing the overall cleaning effect, preventing dust accumulation from affecting the heat dissipation performance, and working in conjunction with the cleaning mechanism 6 to achieve the self-cleaning function of the tunnel light.

[0037] In this embodiment, there are two flushing components 7, which are symmetrically arranged on opposite sides of the cleaning mechanism 6 to spray airflow onto the heat dissipation fins 8 from different angles to improve cleaning efficiency. Each flushing component 7 also includes a connector 703. The connector 703 is a connecting structure and is fixedly connected to one end of the main pipe 701 to realize the rotational connection between the main pipe 701 and other components.

[0038] It also includes an adjustment mechanism 4; the adjustment mechanism 4 is disposed between the moving mechanism 3 and the flushing assembly 7, and is used to adjust the spray angle of the two flushing assemblies 7 so that they can adapt to the needs of different positions when cleaning the heat dissipation fins 8 of the lamp body 2, and avoid interference when the cleaning mechanism 6 passes through the gap between adjacent lamp bodies 2; the adjustment mechanism 4 includes two connecting shafts 401, two frames 402, a crossbeam 403, a through groove 406, two rollers 405, two connecting frames 404, a slide bar 408, a baffle 407, a spring 409, a roller 410, a limiting frame 411, a first guide part 412, a transition part 414, and a second guide part 413.

[0039] Two connecting shafts 401 are rotatably connected to corresponding main pipes 701 via connectors 703, allowing the main pipes 701 to rotate relative to the connecting shafts 401 to adjust the spray angle; two connecting shafts 401 are fixedly connected to one end of two connecting frames 404; the other end of the two connecting frames 404 are rotatably connected to two frame bodies 402, which are fixedly connected to brackets 305 to support the connecting frames 404 and provide a fulcrum for rotation; two rollers 405 are rotatably connected to the two connecting frames 404 to cooperate with the crossbeam 403 to drive the connecting frames 404 to rotate.

[0040] A baffle 407 is fixedly connected to a bracket 305 to provide sliding guidance; the baffle 407 is slidably connected to a slide rod 408, which can slide axially along the baffle 407; one end of the slide rod 408 is fixedly connected to a crossbeam 403, which is a laterally extending beam used to connect two rollers 405; a through groove 406 is machined on the crossbeam 403, forming a long, narrow groove structure, and is slidably connected to two rollers 405 respectively, for... The roller 405 is allowed to roll within the through groove 406 and drive the crossbeam 403 to move; the end of the slide bar 408 away from the crossbeam 403 is rotatably connected to the roller 410, and the axis of the roller 410 is perpendicular to the axis of the slide bar 408 to achieve lateral rolling of the roller 410; the spring 409 is sleeved on the slide bar 408, with one end abutting against the baffle 407 and the other end abutting against the crossbeam 403, to provide elastic restoring force so that the crossbeam 403 tends to the initial position.

[0041] The limiting frame 411 is fixedly connected to the track 306 to guide the movement path of the roller 410. The first guide part 412, the transition part 414 and the second guide part 413 are sequentially machined on the limiting frame 411. The transition part 414 is a sloping or arc-shaped structure to smoothly connect the first guide part 412 and the second guide part 413. The setting position of the first guide part 412 corresponds to the lighting position of the lamp body 2 (i.e., the main body area of ​​the lamp body 2). The setting position of the second guide part 413 corresponds to the interval position between two adjacent lamp bodies 2. Compared with the first guide part 412, the second guide part 413 is closer to the back plate 308 to form a position offset to change the running position of the roller 410.

[0042] Furthermore, when the roller 410 is in the first guide section 412, the spray direction of the multiple nozzles 702 is parallel to the arrangement direction of the heat dissipation fins 8 and is aligned with the lens area of ​​the lamp body 2, thereby achieving effective rinsing and cleaning of the heat dissipation fins 8 and the lens; when the roller 410 is in the second guide section 413, the spray direction of the multiple nozzles 702 is turned to the position of the corresponding cleaning mechanism 6, avoiding spray interference and assisting in cleaning the cleaning mechanism 6 itself.

[0043] In actual use, as the cleaning mechanism 6 moves along the track 306 under the drive of the moving mechanism 3, the roller 410 rolls along the first guide portion 412, the transition portion 414, and the second guide portion 413 on the limiting frame 411. When the roller 410 is located at the first guide portion 412, the crossbeam 403 pushes the two rollers 405 through the through slot 406, causing the two connecting frames 404 to rotate, thereby adjusting the two main pipes 701 so that the spray direction is parallel to the heat dissipation fins 8, realizing the airflow scouring of the heat dissipation fins 8 and lens of the lamp body 2. When the cleaning mechanism 6 approaches the interval between adjacent lamp bodies 2, the roller 410 enters the second guide portion 413 through the transition portion 414, sliding... The sliding of rod 408 causes spring 409 to deform, and crossbeam 403 moves accordingly, driving connecting frame 404 to rotate in the opposite direction. This adjusts the spray direction of main pipe 701 towards cleaning mechanism 6. When spraying at intervals, it can blow off impurities on cleaning mechanism 6, thus ensuring the cleaning of the next set of lamp bodies 2. At the same time, the elastic force of spring 409 ensures a smooth transition. When returning to the first guide part 412, spring 409 resets sliding rod 408 and crossbeam 403, realizing automatic angle adjustment. This allows adjustment mechanism 4 to work in conjunction with air supply component 5 and flushing component 7 to achieve continuous and adaptive cleaning of multiple sets of lamp bodies 2, improving cleaning efficiency and reducing mechanical wear.

[0044] The first guide portion 412, the transition portion 414, and the second guide portion 413 are of the same size and match the roller 410, which can prevent the roller 410 from shaking within the first guide portion 412, the transition portion 414, and the second guide portion 413.

[0045] In addition, another embodiment of the present invention provides a method for using a self-cleaning tunnel light, comprising the following steps: starting the motor 301, and through the transmission of the first synchronous pulley 303, the synchronous belt and the second synchronous pulley 309, driving the traveling wheel 304 to roll along the track 306, thereby driving the bracket 305 and the cleaning mechanism 6 to move as a whole along the light-emitting surface direction of the lamp body 2; on the other hand, synchronously transmitting power to the main shaft 601, causing the cleaning brush 602 to rotate, and brushing and cleaning the light-emitting surface of the lamp body 2 to remove surface dust and dirt, ensuring that the light transmittance is restored and the lighting efficiency is maintained; At the same time, the second synchronous pulley 309 drives the second shaft 512 to rotate. Through the meshing transmission of the second gear 511 and the two first gears 510, the two first shafts 509 are driven to rotate synchronously, thereby driving the two screws 504 to rotate in the same direction. The two screws 504 respectively convert the rotational motion into linear motion by threaded engagement with the two sleeves 505, pushing the two pistons 503 to slide back and forth in the two air cylinders 502. Due to the initial misalignment of the two pistons 503, the gas is alternately compressed and drawn in. During the intake stroke of each piston 503, air is drawn from the external environment into the air cylinder 502 through the first one-way valve 506; during the compression stroke, the air in the air cylinder 502 is compressed into a high-pressure airflow, which is then delivered to the main pipe 701 through the second one-way valve 507 and the first pipe 508. Finally, the airflow is evenly sprayed out by multiple nozzles 702 to flush and clean the gaps of the heat dissipation fins 8, so as to remove accumulated dust and restore heat dissipation performance. During the movement of the cleaning mechanism 6 along the track 306, the roller 410 continuously rolls along the first guide part 412, the transition part 414 and the second guide part 413 on the limiting frame 411 to achieve automatic adjustment of the spray angle. Specifically, when the roller 410 is located at the first guide part 412, the slide bar 408 is in a higher position, and the crossbeam 403 pushes the two rollers 405 through the through groove 406, causing the two connecting frames 404 to rotate around the frame body 402, thereby adjusting the posture of the two main pipes 701, so that the spray direction of the multiple nozzles 702 is parallel to the arrangement direction of the heat dissipation fins 8 and is aimed at the lens area of ​​the lamp body 2, so as to achieve precise airflow flushing of the heat dissipation fins 8 and the lens, and improve the thoroughness of cleaning. When the cleaning mechanism 6 approaches the interval position of the adjacent lamp body 2, the roller 410 is guided into the second guide part 413 through the inclined or arc surface of the transition part 414. The slide rod 408 slides down along the baffle 407 and compresses the spring 409. The crossbeam 403 moves down accordingly and drives the two rollers 405 to move in the opposite direction through the through groove 406, so that the two connecting frames 404 rotate in the opposite direction. This adjusts the posture of the two main pipes 701 and turns the spray direction of the multiple nozzles 702 toward the position of the cleaning mechanism 6, blows off the residual impurities on the cleaning mechanism 6, avoids secondary contamination of the lamp body 2 by impurities, and ensures that the cleaning process is continuous and undisturbed. When the roller 410 returns to the first guide 412, under the limit of the first guide 412, the spring 409 releases elastic potential energy, pushing the slide bar 408 and the crossbeam 403 to reset, thereby realizing the automatic recovery of the spray angle; By executing the above steps in a coordinated manner, the self-cleaning tunnel lights can achieve fully automatic cleaning, improving lighting efficiency, heat dissipation performance and service life, while reducing energy consumption and manual maintenance requirements.
