Description

Technical Field

[0001] The present invention relates to the technical field of urban rail transit signal maintenance, and in particular to an urban rail transit signal monitoring and maintenance support device. Background Art

[0002] In urban rail transit systems, traffic lights are crucial for ensuring safe train operation. The clarity of their displays is directly linked to train dispatch efficiency and driving safety. Because traffic lights are often located outdoors, they are susceptible to dust, oil, and rain stains. This accumulation of stains is particularly rapid in areas with heavy traffic and complex environmental conditions. Failure to promptly clean traffic lights can severely impact their display quality, posing potential risks to train operations.

[0003] Although existing urban rail transit signal monitoring and maintenance support devices are designed with automated cleaning mechanisms, the cleaning brush heads of these devices inevitably wear out after long-term use. Existing devices are unable to adjust according to the degree of brush head wear. When the brush head is worn, its fit with the surface of the traffic light decreases significantly. Due to the wear of the brush head, the brush head is insufficient in length and cannot fully contact the surface of the traffic light, resulting in incomplete cleaning. Furthermore, the angle of the brush head shifts after wear, resulting in partial leakage. This design makes the reliability of cleaning completely dependent on the integrity of the brush head, unable to meet long-term, high-frequency cleaning needs, and difficult to achieve continuous and reliable cleaning of traffic lights. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, an object of the present invention is to provide an urban rail transit signal monitoring and maintenance support device, which can continuously and reliably clean traffic lights.

[0005] The purpose of the present invention is achieved by adopting the following technical solutions:

[0006] A support device for urban rail transit signal monitoring and maintenance includes: a support frame, a traffic light and a cleaning mechanism; the traffic light is installed on the support frame; the cleaning mechanism includes a first-direction linear drive device, a translation seat, a second-direction linear drive device and a cleaning assembly; the first-direction linear drive device is installed on the support frame, the output part of the first-direction linear drive device is connected to the translation seat and supports the translation seat, and the movement directions of the first-direction linear drive device and the second-direction linear drive device are set at a non-zero angle; the second-direction linear drive device is installed in the translation seat, and the output part of the second-direction linear drive device is connected to the cleaning assembly to drive the cleaning assembly close to or away from the traffic light.

[0007] Furthermore, the cleaning assembly includes a cleaning frame, a motor and a rolling brush. The cleaning frame is connected to the output part of the second direction linear drive device and is supported by the second direction linear drive device. The motor is installed on the cleaning frame and is transmission-connected to the rolling brush.

[0008] Furthermore, the cleaning mechanism also includes a control module, a detergent holding box, a water pump, a water pipe and multiple nozzles, the control module is electrically connected to the first direction linear drive device, the second direction linear drive device, the motor and the water pump; the detergent holding box, the water pump, the water pipe and the multiple nozzles are connected in sequence along the direction of water flow, and the multiple nozzles are all installed on the translation seat.

[0009] Furthermore, the plurality of nozzles are distributed at intervals along the movement direction of the translation seat.

[0010] Furthermore, the support frame includes a main frame and a lifting frame, the main frame is provided with a guide column, and the lifting frame is movably connected to the guide column; the first direction linear drive device is installed on the lifting frame.

[0011] Furthermore, the support frame is provided with a lifting drive device, the lifting drive device is located on the lifting frame, and the output part of the lifting drive device is connected to the lifting frame and supports the lifting frame.

[0012] Furthermore, the lifting frame is provided with a guide rail with the same movement direction as that of the first-direction linear drive device, and the translation seat is provided with a slide groove, and the guide rail is slidably matched with the slide groove.

[0013] Furthermore, a limit plate is provided on a side of the guide rail away from the lifting frame, and the limit plate is located on the movement track of the translation seat.

[0014] Furthermore, the support frame also includes a base, a solar panel and a battery; the base is installed at the bottom of the main frame, the solar panel and the battery are electrically connected, and the battery is used to power the support frame, the traffic light and the cleaning mechanism.

[0015] Furthermore, the cleaning mechanism also includes a sunshade cover, which is located above the translation seat and is used to protect the cleaning component.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Based on the first-direction linear drive device being installed on the support frame, the output portion of the first-direction linear drive device is connected to the translation seat and supports the translation seat. This connection and support structure allows the translation seat to always remain stable during movement. Even after long-term use, the translation seat will not become loose or shake due to frequent movement, and the second-direction linear drive device and cleaning assembly installed on the translation seat can always maintain a stable working state. This effectively solves the problem of uneven contact between the cleaning assembly and the surface of the traffic light and the intermittent cleaning effect caused by unstable movement of the traditional translation structure, ensuring that each cleaning is in place and greatly improving the reliability of cleaning.

[0018] 2. The first-direction linear drive device and the second-direction linear drive device are arranged at a non-zero angle. This dual-direction drive arrangement allows the cleaning assembly to move flexibly in two different directions. This design avoids the problem of traditional single-direction cleaning devices that can only clean a specific area and cannot completely remove all stains. It ensures that each cleaning reaches the entire traffic light, providing the foundation for continuous and reliable cleaning and significantly improving cleaning comprehensiveness.

[0019] 3. Based on the output part of the first-direction linear drive device being connected to the translation seat and supporting the translation seat, the second-direction linear drive device is installed in the translation seat, and the output part of the second-direction linear drive device is connected to the cleaning assembly to drive the cleaning assembly towards or away from the traffic light. When the first-direction linear drive device drives the translation seat and the cleaning assembly to translate, the second-direction linear drive device can first drive the cleaning assembly away from the traffic light, so that a safe distance is maintained between the two, effectively avoiding scratches between the cleaning assembly and the traffic light during the translation process, and preventing the surface of the traffic light from being scratched or damaged. After translating to the cleaning position, the second-direction linear drive device drives the cleaning assembly towards the traffic light to ensure sufficient cleaning force; after cleaning is completed, it can drive the cleaning assembly away again, providing safety protection for subsequent translation and resetting. This design effectively solves the problem that the traditional cleaning assembly is fixedly connected to the translation structure and easily scratches the traffic light during translation. It greatly improves the safety of the traffic light during the cleaning process and also provides reliable protection for the long-term stable operation of the device.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element, or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] See also Figure 1-Figure 4, a preferred embodiment of the present invention is a support device for urban rail transit signal monitoring and maintenance, comprising: a support frame 1, a traffic light 2 and a cleaning mechanism 3; the traffic light 2 is mounted on the support frame 1; the cleaning mechanism 3 comprises a first direction linear drive device 31, a translation seat 32, a second direction linear drive device 33 and a cleaning assembly 34; the first direction linear drive device 31 is mounted on the support frame 1, the output portion of the first direction linear drive device 31 is connected to the translation seat 32, and supports the translation seat 32, and the movement directions of the first direction linear drive device 31 and the second direction linear drive device 33 are arranged at a non-zero angle; the second direction linear drive device 33 is mounted in the translation seat 32, and the output portion of the second direction linear drive device 33 is connected to the cleaning assembly 34 to drive the cleaning assembly 34 close to or away from the traffic light 2.

[0029] In daily use scenarios, the cleaning mechanism 3 is in the initial standby area. The output portion of the first-direction linear drive device 31 is in the initial position, stably supporting the translation seat 32 in an area away from the front of the traffic light 2. At this time, the translation seat 32 and the second-direction linear drive device 33 and the cleaning component 34 installed thereon do not block the normal signal display of the traffic light 2. The output portion of the second-direction linear drive device 33 is in a retracted state, and the cleaning component 34 is stored inside the translation seat 32, maintaining a safe distance from the traffic light 2, which not only avoids the erosion of dust, water vapor, etc. on the cleaning component 34, but also ensures that the light propagation of the traffic light 2 is not disturbed, meeting the requirements of normal indication of rail transit signals. When dust and stains accumulate on the surface of the traffic light 2 and need to be cleaned, the first-direction linear drive device 31 starts working first. Its output part will move along the set first direction with the translation seat 32. Because the first-direction linear drive 31 itself supports the translation base 32, much like moving a tray steadily with your hand, the translation base 32, along with the second-direction linear drive 33 and cleaning assembly 34 mounted thereon, can smoothly change position in the lateral direction (e.g., left-right direction) without shaking or shifting. As the translation base 32 moves, the cleaning assembly 34 also moves with it, slowly approaching the area where the traffic light 2 is located. Once it reaches a starting position just in line with the traffic light 2 and suitable for transverse cleaning, the first-direction linear drive 31 stops, and the translation base 32 becomes fixed in this position, preventing further movement. This allows the cleaning assembly 34 to approach the traffic light 2 and perform cleaning. The second-direction linear drive 33 then activates, its output portion propelling the cleaning assembly 34 toward the traffic light 2. Because the first and second directions form a non-zero angle (e.g., perpendicular), the cleaning assembly 34, while still in a fixed transverse position, approaches the surface of the traffic light 2 longitudinally. When the cleaning assembly 34 contacts the surface of the traffic light 2 and reaches the appropriate cleaning pressure, the second-direction linear drive 33 pauses. The first-direction linear drive 31 then restarts, slowly moving the translating base 32 and cleaning assembly 34 laterally. During this lateral movement, the cleaning assembly 34 thoroughly wipes the surface of the traffic light 2. After cleaning is complete, the second-direction linear drive 33 first returns the cleaning assembly 34 to its initial storage position. The first-direction linear drive 31 then moves the translating base 32 back to a standby area away from the traffic light 2, returning the entire cleaning mechanism 3 to its initial state.

[0030] Apparently, since the first-direction linear drive device 31 is mounted on the support frame 1, the output portion of the first-direction linear drive device 31 is connected to the translation seat 32 and supports the translation seat 32. This connection and support structure ensures that the translation seat 32 remains stable during movement. Even after long-term use, the translation seat 32 will not become loose or shaken due to frequent movement, and the second-direction linear drive device 33 and cleaning assembly 34 mounted on the translation seat 32 can maintain a stable working state. This effectively solves the problem of traditional translation structures, which lead to uneven contact between the cleaning assembly 34 and the surface of the traffic light 2 and inconsistent cleaning results due to unstable movement. It ensures that the cleaning assembly 34 is always clean and significantly improves cleaning reliability. The movement directions of the first-direction linear drive device 31 and the second-direction linear drive device 33 are arranged at a non-zero angle. This bidirectional drive layout allows the cleaning assembly 34 to move flexibly in two different directions. Regardless of the location of the stains on the surface of the traffic light 2, the cleaning assembly 34 can reach them by adjusting its direction, achieving a comprehensive cleaning of the surface of the traffic light 2. This design avoids the problem that traditional single-direction cleaning devices can only clean local areas and cannot completely remove all stains, ensuring that each cleaning can cover the entire traffic light 2, providing a basic guarantee for continuous and reliable cleaning, and significantly improving the comprehensiveness of cleaning. Based on the output portion of the first-direction linear drive device 31 being connected to the translation seat 32 and supporting the translation seat 32, the second-direction linear drive device 33 is installed in the translation seat 32, and the output portion of the second-direction linear drive device 33 is connected to the cleaning assembly 34 to drive the cleaning assembly 34 closer to or away from the traffic light 2. When the first-direction linear drive device 31 drives the translation seat 32 and the cleaning assembly 34 to translate, the second-direction linear drive device 33 can first drive the cleaning assembly 34 away from the traffic light 2, so that a safe distance is maintained between the two, effectively avoiding scratches between the cleaning assembly 34 and the traffic light 2 during the translation process, and preventing the surface of the traffic light 2 from being scratched or damaged. After translating to the cleaning position, the second-direction linear drive device 33 drives the cleaning assembly 34 closer to the traffic light 2, ensuring sufficient cleaning force. After cleaning is complete, the cleaning assembly 34 is driven away again, providing safety for subsequent translation and reset. This design effectively solves the problem of traditional cleaning assemblies being fixedly connected to the translation structure and easily scratching the traffic light 2 during translation. This greatly improves the safety of the traffic light 2 during the cleaning process and provides reliable guarantees for the long-term stable operation of the device.

[0031] Preferably, in this embodiment, the cleaning assembly 34 includes a cleaning frame 341, a motor 342, and a rolling brush 343. The cleaning frame 341 is connected to and supported by the output portion of the second-direction linear drive device 33. The motor 342 is mounted on the cleaning frame 341 and is in transmission connection with the rolling brush 343. This arrangement of the cleaning frame 341 being connected to and supported by the output portion of the second-direction linear drive device 33 provides a very secure fixation of the cleaning frame 341. When the cleaning assembly 344 approaches or moves away from the traffic light 2, and the rolling brush 343 is performing a cleaning operation, the cleaning frame 341 remains in place even when subjected to a certain degree of force, thereby maintaining a stable operating position for the rolling brush 343. Furthermore, this connection facilitates disassembly and assembly. When maintenance or replacement of the rolling brush 343 or motor 342 is required, the cleaning assembly 341 can be easily performed by the operator, reducing maintenance effort and time. The motor 342 and the rolling brush 343 are designed to be connected in a transmission manner. This transmission method enables efficient cleaning of the surface of the traffic light 2. Dust and stains on the surface of the traffic light 2 come in various forms, some of which are firmly attached. Driven by the motor 342, the rolling brush 343 performs a rolling wipe, which can more thoroughly remove the stains through continuous friction compared to a static wiping method. For example, stubborn stains formed on the surface of the traffic light 2 due to long-term accumulation can be gradually peeled off under the continuous action of the rolling brush 343, effectively preventing residual stains and improving the cleanliness and efficiency of cleaning. The cleaning frame 341 is supported by the second-direction linear drive device 33 and connected to its output portion, giving the cleaning assembly 344 flexible position adjustment capabilities. When cleaning traffic lights 2 of different sizes and installation locations, the position of the cleaning frame 341 can be adjusted according to actual needs using the second-direction linear drive device 33, thereby controlling the distance and contact force between the rolling brush 343 and the surface of the traffic light 2. For traffic lights 2 with fragile surfaces, the rolling brush 343 can be positioned appropriately away to reduce contact force and avoid damage. For heavily soiled traffic lights 2, the rolling brush 343 can be positioned appropriately close to increase contact force to ensure effective cleaning. This precise position control significantly improves the adaptability of the cleaning assembly 34, providing more reliable guarantees for safe and effective cleaning of traffic lights 2, thereby enhancing the practicality of the entire device. The second-direction linear drive device 33 can be an electric push-pull rod, a hydraulic rod, or a pneumatic rod.

[0032] Preferably, in this embodiment, the cleaning mechanism 3 further includes a control module 35, a detergent tank 36, a water pump 37, a water conduit 38, and multiple nozzles 39. The control module 35 is electrically connected to the first-direction linear drive 31, the second-direction linear drive 33, the motor 342, and the water pump 37. The detergent tank 36, the water pump 37, the water conduit 38, and the multiple nozzles 39 are sequentially connected along the direction of water flow. The multiple nozzles 39 are all mounted on the translation base 32. The control module 35 is electrically connected to the first-direction linear drive 31, the second-direction linear drive 33, the motor 342, and the water pump 37. The multiple nozzles 39 are all mounted on the translation base 32. This centralized control and installation method ensures more orderly operation of the entire cleaning mechanism 3. The control module 35 coordinates the actions of various components, avoiding operational confusion. The nozzles 39 are mounted on the translation base 32 and maintain a stable mounting position as they move with the translation base 32, preventing positional shifts that may affect the water spraying effect. This electrical connection and installation method also facilitates later maintenance. If a component malfunctions, personnel can quickly locate it using feedback from the control module 35. The nozzle 39 features a simple installation structure and is easily disassembled and replaced, reducing maintenance time and labor costs. The detergent tank 36, water pump 37, water conduit 38, and multiple nozzles 39 are sequentially connected along the water flow path. This water flow path design enables efficient cleaning of the surface of the traffic light 2. Some stains on the surface of the traffic light 2 are difficult to completely remove using the rolling brush 343 alone. Under the action of the water pump 37, detergent is sprayed from the nozzle 39 through the water conduit 38 to soften the stains. For example, stubborn oil-based stains on the surface of the traffic light 2 can be thoroughly removed by detergent, which can then be wiped away by the rolling brush 343 to completely remove the stains. This effectively prevents stubborn stains from remaining and further improves cleaning efficiency. Furthermore, electrically connecting the control module 35 to multiple components provides the cleaning mechanism 3 with flexible cleaning and adjustment capabilities. When cleaning traffic lights 2 with different levels of stains, the water pump 37 can be adjusted through the control module 35. For cases with less stains, the water pump 37 can be controlled to reduce the amount of detergent sprayed; for cases with more stubborn stains, the amount of detergent sprayed can be increased, and the drive device and motor 342 are coordinated to allow the rolling brush 343 to cooperate in multiple wiping. This precise adjustment based on actual conditions can save detergent while ensuring the cleaning effect, and also avoid damage to the surface of the traffic light 2 caused by excessive cleaning, thereby improving the practicality and economy of the device. The first-direction linear drive device 31 can be an electric push-pull rod, a hydraulic rod, or a pneumatic rod; the control module 35 can be a PLC, a microcomputer, or a single-chip microcomputer.

[0033] Preferably, in this embodiment, the multiple nozzles 39 are distributed at intervals along the movement direction of the translation seat 32. The multiple nozzles 39 are distributed at intervals along the movement direction of the translation seat 32, which can achieve progressive and comprehensive spraying of the surface of the traffic light 2. When the translation seat 32 drives the nozzles 39 to move, the front nozzle 39 first sprays detergent on the corresponding area of ​​the traffic light 2. As the translation seat 32 advances, the rear nozzle 39 will perform a second supplementary spraying on the preceding area. Taking the case where there is a long strip of stain on the surface of the traffic light 2 as an example, the first nozzle 39 first sprays the starting end of the stain. After the translation seat 32 moves, the second nozzle 39 then sprays the middle section of the stain, and the third nozzle 39 covers the end of the stain. The "relay spraying" formed by the staggered distribution avoids the problem of insufficient stain pretreatment caused by insufficient spraying range of a single nozzle 39, thereby improving the integrity of the pretreatment before cleaning. Furthermore, the multiple nozzles 39 are designed to be spaced apart along the direction of movement of the translation seat 32, giving the spraying operation a stronger ability to be adjusted in a targeted manner. The control module 35 can independently control the nozzles 39 at different positions according to the distribution characteristics of the stains on the surface of the traffic light 2. If the stains on the left side of the traffic light 2 are thicker, the nozzles 39 on the left side can be controlled to increase the spraying pressure and dosage, while the nozzles 39 in the middle and right sides maintain normal spraying; if the stains in a certain area have been basically cleaned, the nozzles 39 in the corresponding positions can be individually turned off. This "on-demand start and stop, precise quantity control" adjustment method can not only avoid the ineffective consumption of detergent, but also prevent the risk of corrosion on the surface of the traffic light 2 caused by excessive local spraying, taking into account both cleaning efficiency and equipment protection.

[0034] Preferably, in this embodiment, the support frame 1 comprises a main frame 11 and a lifting frame 12. The main frame 11 is provided with guide posts 111, to which the lifting frame 12 is movably coupled. The first-direction linear drive device 31 is mounted on the lifting frame 12. This arrangement provides a stable mounting and movement support for the lifting frame 12, while the flexible coupling of the lifting frame 12 to the guide posts 111 ensures both a secure and flexible connection. During the raising and lowering of the lifting frame 12, the guide posts 111 effectively limit its movement, preventing it from shifting or shaking, ensuring that it always moves smoothly in the predetermined direction. Furthermore, this simple and clear structure allows for quick and easy maintenance and replacement of the lifting frame 12 or the guide posts 111. This facilitates easy operation and reduces maintenance effort. Furthermore, the design of the lifting frame 12 being movably coupled to the guide posts 111 provides the device with enhanced height adjustment capabilities. Staff can adjust the height of the lift 12 by controlling the relevant drive mechanism based on the actual height of the traffic light 2 and the height distribution of surface stains. If the upper portion of the traffic light 2 is heavily soiled, the lift 12 can be adjusted to a relatively high position, allowing the cleaning assembly 34 to focus more on the upper portion. If the lower portion is heavily soiled, the lift 12 can be lowered appropriately. This precise height adjustment allows for more targeted cleaning, ensuring effective cleaning while reducing unnecessary movement and improving cleaning efficiency.

[0035] Preferably, in this embodiment, the support frame 1 is equipped with a lifting drive device 13. The lifting drive device 13 is located on the lifting frame 12, and the output portion of the lifting drive device 13 is connected to and supports the lifting frame 12. The lifting drive device 13 is located on the lifting frame 12, and its output portion is connected to and supports the lifting frame 12. This integrated connection and support structure provides a more stable installation of the lifting frame 12. During the lifting and lowering process of the lifting frame 12, the lifting drive device 13 provides stable support, preventing the lifting frame 12 from sinking or tilting due to the weight of the lifting frame 12 and the components it carries, ensuring that the lifting frame 12 always moves in a stable position along the guide posts 111. Furthermore, the output portion of the lifting drive device 13 is connected to and supports the lifting frame 12, enabling smooth and efficient lifting and lowering of the lifting frame 12. The lifting drive device 13 provides a continuous and uniform driving force, driving the lifting frame 12 to move smoothly along the guide posts 111. For example, when the lifting frame 12 needs to be raised to clean a high-rise traffic light 2, the lifting drive 13 outputs a stable driving force, slowly and smoothly raising the lifting frame 12. When the lifting frame 12 needs to be lowered, the lifting drive 13 orderly retracts the output portion, allowing the lifting frame 12 to descend smoothly. This smooth lifting and lowering avoids shaking of the cleaning assembly 34 caused by unstable lifting, ensuring smooth subsequent cleaning operations and improving the reliability of the lifting operation. Furthermore, the lifting drive 13 provides driving force for the lifting frame 12, giving the device greater precision and controllability in height adjustment. The lifting drive 13 can be an electric push-pull rod, a hydraulic rod, or a pneumatic rod.

[0036] Preferably, in this embodiment, the lifting frame 12 is equipped with a guide rail 121 that aligns with the movement direction of the first-direction linear drive device 31. The translating seat 32 is equipped with a slide groove 321, with which the guide rail 121 slidably engages. This sliding engagement between the guide rail 121 and the slide groove 321 provides a more stable connection between the translating seat 32 and the lifting frame 12. The guide rail 121 is arranged along the direction of movement of the first-direction linear drive device 31, and the slide groove 321 mates with it one-to-one, like a dedicated "track" for the movement of the translating seat 32. This effectively limits the movement trajectory of the translating seat 32 and prevents lateral deviation or shaking of the translating seat 32 during movement. The alignment of the guide rail 121 and the slide groove 321 along the direction of movement of the first-direction linear drive device 31 provides greater adaptability in the movement and adjustment of the translating seat 32. Due to the high precision of the engagement between the guide rail 121 and the slide groove 321, the translating seat 32 can achieve fine, small-scale movement and adjustment under the drive of the first-direction linear drive device 31. For example, when the cleaning assembly 34 needs to be aimed at a specific stain on the surface of the traffic light 2, the precise guidance of the guide rail 121 and the slide 321 allows the translation base 32 to stop accurately at the corresponding position, allowing the cleaning assembly 34 to precisely apply to the stain. This precise movement and adjustment capability reduces ineffective movement, improves the targetedness and efficiency of cleaning, and can also adapt to the cleaning needs of traffic lights 2 of different sizes, enhancing the versatility of the device.

[0037] Preferably, in this embodiment, a limit plate 122 is provided on the side of the guide rail 121 away from the lifting frame 12, and the limit plate 122 is located on the motion trajectory of the translation seat 32. The limit plate 122 is installed on the side of the guide rail 121 away from the lifting frame 12 and is located on the motion trajectory of the translation seat 32, forming a clear physical protection structure. Designing the limit plate 122 to be located on the motion trajectory of the translation seat 32 can provide precise stroke control for the movement of the translation seat 32. When the translation seat 32 moves to the end of the trajectory driven by the first-direction linear drive device 31, the translation seat 32 will first contact the limit plate 122. The limit plate 122 offsets the inertia force of the translation seat 32 through its own rigidity, forcing the translation seat 32 to stop moving. For example, after the cleaning assembly 34 completes cleaning the edge area of ​​the traffic light 2, the translation seat 32 continues to move close to the end of the guide rail 121. At this time, the limit plate 122 will prevent the translation seat 32 from moving further, preventing the translation seat 32 from exceeding the preset stroke due to inertia, preventing the cleaning assembly 34 from colliding with other components such as the support frame 1, and also preventing the translation seat 32 from getting stuck due to the disengagement of the slide 321 and the guide rail 121, thereby ensuring the safety and controllability of the translation movement. The limit plate 122 is set on the side of the guide rail 121 away from the lifting frame 12, giving the device the ability to adapt to different working conditions. During the device debugging stage, the maximum movement stroke of the translation seat 32 can be flexibly set by adjusting the installation position of the limit plate 122 (such as adding or removing gaskets to change the distance) to adapt it to traffic lights 2 of different sizes. For small traffic lights 2, the limit plate 122 is adjusted inward to shorten the travel and prevent the cleaning assembly 34 from moving in vain. For large traffic lights 2, the limit plate 122 is adjusted outward to extend the travel and ensure that the cleaning assembly 34 can cover the entire surface of the traffic light 2. This adjustable limit design allows the device to adapt to different scenarios without replacing core components, improving the device's versatility and flexibility.

[0038] Preferably, in this embodiment, the support frame 1 further includes a base 14, a solar panel 15 and a battery 16; the base 14 is mounted on the bottom of the main frame 11, the solar panel 15 and the battery 16 are electrically connected, and the battery 16 is used to power the support frame 1, the traffic light 2 and the cleaning mechanism 3. The base 14 is mounted on the bottom of the main frame 11 to provide stable support for the entire device, and the solar panel 15 and the battery 16 are connected through a circuit to form an independent power supply system, with a clear installation structure and high integration. The solar panel 15 can be flexibly installed on the sunny side of the support frame 1 (such as the top of the main frame 11) without relying on external grid wiring, and is particularly suitable for scenarios where there is no fixed power supply interface along the track; the battery 16, as an energy storage component, can form a stable circuit connection with each electrical component (such as the drive device, control module 35), and the power supply path is clear. The solar panel 15 and the battery 16 work together to provide power, which can provide a continuous and stable energy guarantee for the device. During daytime sunlight, solar panels 15 convert solar energy into electrical energy, a portion of which directly powers traffic lights 2, cleaning mechanisms 3, and other components, while the remaining portion is stored in batteries 16. At night or on cloudy days when sunlight is insufficient, batteries 16 automatically release this energy to maintain operation of various components. For example, in areas along the railway line without long-term access to mains electricity, traditional grid-dependent devices are prone to malfunctioning due to power outages. However, this design, through the synergy of solar energy and batteries 16, ensures the normal operation of traffic lights 2 and scheduled maintenance of cleaning mechanisms 3, preventing signal failures or equipment outages caused by power outages and improving operational reliability. Furthermore, the power supply design of solar panels 15 and batteries 16 makes the device more environmentally adaptable and energy-efficient. For remote areas along the railway line and temporary stations with poor power supply conditions, solar energy alone can achieve autonomous power supply without laying additional cables, reducing reliance on the fixed power grid. Furthermore, as a renewable energy source, solar energy reduces traditional electricity consumption, and the storage function of batteries 16 allows for adjustable output according to power demand. During the day, when the cleaning mechanism 3 is operating and solar power generation is sufficient, the battery 16 can reduce discharge. At night, when only the traffic light 2 is operating, the battery 16 outputs a stable, low-power supply. This energy regulation method not only adapts to the power supply needs of different scenarios, but also conforms to the concept of energy conservation, improving the practicality and environmental friendliness of the device.

[0039] Preferably, in this embodiment, the cleaning mechanism 3 also includes a sunshade 4 located above the translation seat 32 to protect the cleaning assembly 34. Positioning the sunshade 4 above the translation seat 32 provides continuous environmental protection for the cleaning assembly 34. During daily use, when the device is not cleaning, the cleaning assembly 34 is exposed to the outside environment and susceptible to direct sunlight, rain, and dust accumulation. For example, prolonged exposure to sunlight can cause the bristles of the rolling brush 343 to age and harden, affecting cleaning effectiveness; rainwater seeping into the motor 342 can cause circuit failure. The sunshade 4 blocks sunlight, preventing the cleaning assembly 34 from aging due to high temperatures. It also prevents rainwater from directly reaching the assembly, reducing the risk of moisture. It also reduces dust accumulation on the assembly surface, keeping the cleaning assembly 34 in optimal condition and extending its service life. Furthermore, positioning the sunshade 4 above the translation seat 32 allows the device to adapt to diverse environments. For areas with strong sunlight and heavy rain, the sunshade 4 can be made of materials with stronger sun protection and waterproof properties (such as high-strength plastic, waterproof canvas, etc.) to further enhance the protective effect; for areas along the track with high dust, the coverage area of ​​the sunshade 4 can be appropriately increased to reduce the gaps for dust to enter the cleaning component 34. In addition, the sunshade 4 will not affect the normal operation of the cleaning component 34. When the cleaning component 34 is driven by the second-direction linear drive device 33 and approaches the traffic light 2, the sunshade 4 moves synchronously with the translation seat 32 and will not block or hinder the cleaning action. This design, which can provide effective protection without interfering with normal operation, improves the practicality of the device in different environments.
