Description

Technical Field

[0001] This invention relates to the field of light replacement technology, specifically to a photovoltaic-powered LED strobe light head replacement device for warning posts. Background Technology

[0002] In scenarios such as traffic warnings, construction protection, and emergency rescue, warning posts serve as important safety warning devices, and their core functions rely on stable light warnings and continuous power supply. Traditional warning posts mostly use external power supplies or ordinary batteries for power. In scenarios such as field construction areas without power grid coverage, temporary work sites on highways, and urban flooded sections, there are problems with inconvenient power supply and poor battery life, making it difficult to meet the needs of long-term continuous warning.

[0003] However, the photovoltaic panels on existing photovoltaic power supply warning posts are mostly designed with a fixed angle, which cannot be dynamically adjusted according to the angle of sunlight (or moonlight at night). This results in significant differences in light energy utilization at different times, especially in the early morning, evening, or cloudy weather, where power supply stability drops sharply. At the same time, warning posts are often placed in dusty environments such as roadsides and construction areas where debris easily accumulates. The surface of the photovoltaic panels is prone to adhering to pollutants such as dust, fallen leaves, and mud. If not cleaned in time, this can lead to a reduction in light energy conversion efficiency of more than 30%, and in severe cases, even cause power outages. Manual cleaning requires workers to climb to the top of the warning post, which is not only inefficient but also poses safety risks associated with working at height.

[0004] Furthermore, as a core component of warning posts, LED strobe light heads are prone to failure due to circuit malfunctions and light source aging during long-term use. Currently, the light heads of existing warning posts are mostly directly fixed to the top of the post. Replacement requires workers to climb to a height with tools, remove the fixing bolts, and replace the light. In dangerous scenarios such as highways and flooded sections, the combination of working at heights and road traffic conditions greatly increases the risk of falls and traffic accidents. Additionally, traditional light head installations often rely on threaded connections. Improper force control during disassembly can easily cause the light head casing to crack, increasing material costs and potentially exposing internal conductive components, leading to electric shock risks. In severe weather conditions such as heavy rain, strong winds, and sandstorms, the photovoltaic panels of existing warning posts lack effective protective designs. Rainwater can easily accumulate on the surface of the photovoltaic panels, causing short circuits, while strong winds can cause structural swaying due to the fixed angle of the photovoltaic panels. The poor sealing performance of the connection between the light head and the post allows water to seep into the interior, causing circuit failures, making it difficult to meet the long-term stable operation requirements of complex outdoor environments.

[0005] In view of the shortcomings of the existing technology, there is an urgent need for a warning post device with self-regulating cleaning of photovoltaic panels, rapid lamp head replacement, and strong environmental adaptability, so as to solve the problems of poor power supply stability, low maintenance efficiency, and high safety risks, and meet the actual needs of traffic warning, construction protection and other scenarios. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose an LED strobe light head replacement device for warning posts based on photovoltaic power supply, so as to solve the problems of poor power supply stability, low maintenance efficiency and high safety risks, and meet the actual needs of traffic warning, construction protection and other scenarios.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic-powered LED strobe lamp head replacement device for warning posts, comprising a support column, a replacement chamber installed on the upper surface of the support column, a lamp cover installed above the replacement chamber, a signal transmission device installed above the lamp cover, a photovoltaic panel disposed on the lamp cover, a lamp head installed in the middle of the lamp cover, and further comprising a multi-functional self-adjusting cleaning mechanism and a rapid replacement mechanism; The multi-functional self-adjusting cleaning mechanism is installed on the photovoltaic panel, and the multi-functional self-adjusting cleaning mechanism is used for the self-adjustment and cleaning of the photovoltaic panel's angle. The quick replacement mechanism is installed in the lamp cover; the quick replacement mechanism is used for the quick replacement of the lamp head.

[0008] Preferably, the multifunctional self-adjusting cleaning mechanism includes an internal toothed ring, which is rotatably mounted on the bottom of the outer surface of the lampshade. The tooth surface of the internal toothed ring is engaged with a first rotating tooth, the middle of which is rotatably mounted on the lampshade.

[0009] Preferably, the first control motor is mounted on the lamp cover, a V-shaped support plate is fixedly mounted on the outer surface of the inner toothed ring, a base plate is rotatably mounted on the middle of the end of the V-shaped support plate away from the inner toothed ring, a second control motor is fixedly mounted on the middle of the V-shaped support plate, the drive shaft of the V-shaped support plate passes through the V-shaped support plate and is fixedly mounted on the base plate, and a damper is fixedly mounted on the side of the base plate away from the second control motor.

[0010] Preferably, the multifunctional self-adjusting cleaning mechanism further includes a second rotating tooth, the lower surface of the middle part of the second rotating tooth is rotatably mounted on the substrate, and a spraying device is rotatably mounted on the upper surface of the middle part of the second rotating tooth. The spraying device is fixedly mounted on the substrate on both sides.

[0011] Preferably, the second rotating tooth has an L-shaped scraper symmetrically meshing with its teeth. An auxiliary scraper is rotatably mounted on the end of the L-shaped scraper away from the second rotating tooth, and a pusher is rotatably mounted on the end of the auxiliary scraper away from the L-shaped scraper. The pusher is disposed on the upper surface of the photovoltaic panel. The photovoltaic panel is mounted on the upper surface of the substrate. A rubber strip is installed on the L-shaped scraper for cleaning the surface of the photovoltaic panel.

[0012] Preferably, the quick replacement mechanism includes an adjusting screw, a threaded cylinder is threadedly mounted on the outer side of the adjusting screw, a sliding plate is fixedly mounted on the lower surface of the threaded cylinder, and an angled collar is fixedly mounted on the lower surface of the inner wall of the adjusting screw.

[0013] Preferably, a fixing ring is provided in the middle of the threaded cylinder, and the lower surface of the fixing ring is fixedly installed on the slide. A magnetic socket is provided in the middle of the slide. The fixing ring is installed on the outside of the magnetic socket. A canopy clamp is uniformly fixedly installed on the upper surface of the fixing ring. An angled block is fixedly installed on the side of the canopy clamp away from the fixing ring. The canopy clamp is made of plastic material with certain toughness and strength.

[0014] Preferably, the rapid replacement mechanism further includes a sliding toothed rod, the upper surface of which is fixedly mounted on a sliding plate. The tooth surface of the sliding toothed rod meshes with a turbine, the middle part of which is rotatably mounted in the replacement chamber. A worm gear meshes with the turbine, the middle part of which is rotatably mounted on the replacement chamber. A rotating wheel is fixedly mounted at the end of the worm gear away from the turbine.

[0015] Compared with the prior art, the LED strobe light head replacement device for warning posts based on photovoltaic power supply provided by the present invention has the following beneficial effects: (1) The multi-functional self-regulating cleaning mechanism enables efficient operation and maintenance of photovoltaic panels and ensures power supply stability. This solution utilizes a collaborative design of an internal gear ring, dual control motors, and a damper to construct a photovoltaic panel angle adaptive adjustment system: the first control motor drives the first rotating gear to mesh with the internal gear ring, causing the V-shaped support plate and substrate to dynamically adjust their horizontal orientation according to the angle of sunlight; the second control motor drives the substrate to rotate around the V-shaped support plate, working with the damper to precisely fix the tilt angle, ensuring that the photovoltaic panel always maintains the optimal incident angle with the light, improving the light energy conversion efficiency by more than 40% compared to a fixed-angle design, effectively solving the problem of unstable power supply under different times and weather conditions. Simultaneously, the mechanism integrates a dust monitoring device, a spray device, and an L-shaped scraper. When the dust thickness on the photovoltaic panel surface exceeds a preset threshold, it automatically activates high-pressure water spray and scraper cleaning. The rubber strip and flexible push plate at the bottom of the scraper can cover the edges, corners, and other dead angles of the photovoltaic panel. After cleaning, the light energy conversion efficiency recovers to more than 95% of its initial value, completely replacing manual high-altitude cleaning, significantly improving operation and maintenance efficiency and reducing safety risks.

[0016] (2) The quick replacement mechanism innovates the lamp holder replacement method, reducing operational risks and time costs; This solution abandons the traditional design of disassembling lamp heads at height. Through a "turbine-worm gear-sliding gear" transmission structure and magnetic fixing components, it achieves rapid ground-based lamp head replacement. Workers do not need to climb; they only need to rotate a wheel on the ground. This allows the worm gear to engage the turbine, driving the sliding gear to raise and lower the slide plate and lamp head to the square replacement slot in the replacement chamber. The entire process requires no contact with the top of the warning post. The lamp head fixing uses a combination structure of "angled collar + umbrella-shaped clamp + magnetic socket." Rotating the adjusting screw controls the angled collar to press or release the umbrella-shaped clamp, and the magnetic socket provides rapid positioning, significantly reducing the time required compared to traditional methods. Furthermore, the umbrella-shaped clamp is made of high-toughness plastic, adaptable to lamp heads of different diameters, avoiding the lamp head breakage problem caused by improper force in traditional threaded connections. The magnetic socket has a built-in waterproof sealing ring, which also improves the sealing performance between the lamp head and the base, effectively solving the problems of electric shock risk, high-altitude safety hazards, and material waste during the replacement process.

[0017] (3) Modular structure design improves equipment adaptability and ease of maintenance; This solution breaks down the core functions into a main module of "support column - replacement chamber - lampshade," and independent modules of "multi-functional self-adjusting cleaning mechanism" and "rapid replacement mechanism." These modules connect via standardized interfaces, facilitating production and assembly while allowing for flexible adjustments based on different scenarios. For example, in highway scenarios, the photovoltaic panel area and cleaning frequency can be increased; in urban flooded areas, the waterproof rating of the lampshade and magnetic socket can be enhanced. Furthermore, all components of each module are replaceable. Easily damaged parts such as the rubber strips of the L-shaped scraper, umbrella-shaped clamps, and magnetic sockets can be individually disassembled and replaced without requiring a complete replacement mechanism. This significantly reduces maintenance costs and equipment downtime, improving long-term economic efficiency.

[0018] (4) Strong environmental adaptability design ensures stable operation under complex working conditions; To address harsh environments such as heavy rain, strong winds, and sandstorms, this solution strengthens protective capabilities through structural details: the damper in the photovoltaic panel adjustment mechanism automatically fixes the photovoltaic panel at a 30° tilt angle during heavy rain, preventing short circuits caused by rainwater accumulation; the umbrella-shaped clamp is made of waterproof plastic, and the magnetic socket has a built-in sealing ring, achieving an IP67 waterproof rating after lamp head replacement, capable of withstanding long-term immersion in flooded road sections; the internal gear ring, turbine, worm gear, and other transmission components are all treated with anti-corrosion coatings to resist roadside sand and salt corrosion, extending their service life. Furthermore, the integrated design of the signal transmission device allows for real-time feedback of photovoltaic panel energy efficiency and lamp head operating status, facilitating remote monitoring of equipment operation, early warning of faults, and further improving equipment reliability under complex operating conditions.

[0019] (5) No external power supply required and low energy consumption design expands the scope of application scenarios; This solution uses photovoltaic power as its core, eliminating the need for an external power grid. It can be flexibly deployed in scenarios without power supply, such as highway construction, field rescue, and temporary urban traffic control, solving the core pain point of traditional warning posts: "limited power supply." Meanwhile, the device's control motor, sprinkler system, and other auxiliary components all adopt low-energy-consumption designs. Combined with high-efficiency photovoltaic panels and energy storage batteries, it can achieve 24-hour continuous operation: during the day, the photovoltaic panels collect and store solar energy, and at night, warning signals are released through LED flashing lights. Even in cloudy conditions, it can maintain a stable power supply for more than 3 days through angle adjustment and high-efficiency energy storage. Automatic flashing via photovoltaic activation allows it to operate for 20 days without sunlight, completely eliminating reliance on traditional batteries and reducing environmental pollution caused by discarded batteries, thus meeting the needs of green and environmentally friendly development.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] Example 1, please refer to Figures 1 to 7 As shown: To address the problems mentioned in the technical solutions, this application provides a photovoltaic-powered LED strobe lamp head replacement device for warning posts, including a support column 1, a replacement chamber 11 installed on the upper surface of the support column 1, a lamp cover 12 installed above the replacement chamber 11, a signal transmission device 13 installed above the lamp cover 12, a photovoltaic panel 14 disposed on the lamp cover 12, a lamp head 15 installed in the middle of the lamp cover 12, and also including a multi-functional self-adjusting cleaning mechanism 2 and a rapid replacement mechanism 3; A multi-functional self-adjusting cleaning mechanism 2 is installed on the photovoltaic panel 14. The multi-functional self-adjusting cleaning mechanism 2 is used for the self-adjustment and cleaning of the angle of the photovoltaic panel 14. The quick replacement mechanism 3 is installed in the lamp cover 12; the quick replacement mechanism 3 is used for quick replacement of the lamp holder 15; In this design, a square replacement slot is provided in the middle of the replacement chamber 11, through which the lamp holder 15 can be replaced.

[0025] Specifically, the internal gear ring 21 is rotatably mounted on the bottom of the outer surface of the lamp cover 12. The teeth of the internal gear ring 21 mesh with a first rotating tooth 22. The middle of the first rotating tooth 22 is rotatably mounted on the lamp cover 12. A first control motor 23 is fixedly mounted on the upper surface of the middle of the first rotating tooth 22. The first control motor 23 is mounted on the lamp cover 12. A V-shaped support plate 24 is fixedly mounted on the outer surface of the internal gear ring 21. A base plate 26 is rotatably mounted on the middle of the end of the V-shaped support plate 24 away from the internal gear ring 21. A second control motor 25 is fixedly mounted on the middle of the V-shaped support plate 24. The drive shaft of the V-shaped support plate 24 passes through the V-shaped support plate 24 and is fixedly mounted on the base plate 26. A damper is fixedly mounted on the side of the base plate 26 away from the second control motor 25. Among them, such as Figure 4As shown, the second control motor 25 and the first control motor 23 are both electrically connected to the controller installed in the replacement chamber 11. Through programmed settings and control, the angle of the photovoltaic panel 14 is self-adjusted. When the programmed settings enable the inner gear ring 21 to rotate adaptively over time, the inner gear ring 21 drives the substrate 26 to move the photovoltaic panel 14 in sync with the sunlight. Through programmed control of the second control motor 25, the substrate 26 can be driven to rotate in the V-shaped support plate 24. The damper can keep the photovoltaic panel 14 at the optimal angle with the sunlight, so that the photovoltaic panel 14 can always maintain the optimal angle with the sunlight, thereby enabling the photovoltaic panel 14 to maintain high-efficiency light energy utilization.

[0026] Specifically, the lower surface of the middle part of the second rotating tooth 27 is rotatably mounted on the substrate 26, and the upper surface of the middle part of the second rotating tooth 27 is rotatably mounted with a spraying device 29. The spraying device 29 is fixedly mounted on the substrate 26 on both sides. The teeth of the second rotating tooth 27 are symmetrically engaged with an L-shaped scraper 28. An auxiliary scraper is rotatably mounted on one end of the L-shaped scraper 28 away from the second rotating tooth 27, and a pusher is rotatably mounted on the other end of the auxiliary scraper away from the L-shaped scraper 28. The pusher is set on the upper surface of the photovoltaic panel 14. The photovoltaic panel 14 is mounted on the upper surface of the substrate 26. A rubber strip is installed on the L-shaped scraper 28 for cleaning the surface of the photovoltaic panel 14. Among them, such as Figure 3 and Figure 4 As shown, the second rotating tooth 27 is driven by a small servo motor in the middle, and the small servo motor is electrically connected to the controller. The controller controls the rotation of the second rotating tooth 27. The rotation of the second rotating tooth 27, through its meshing with the L-shaped scraper plate 28, causes the L-shaped scraper plates 28 on both sides to simultaneously scrape the surface of the photovoltaic panel 14. Simultaneously, the spraying device 29, through programmed control, sprays water to clean the surface of the photovoltaic panel 14. A dust monitoring device is installed on the surface of the photovoltaic panel 14. This device monitors the dust on the surface of the photovoltaic panel 14 in real time. When the dust level exceeds a set threshold, the controller in the replacement chamber 11 activates the spraying device 29 and the small servo motor, thereby quickly cleaning the surface of the photovoltaic panel 14. Figure 3 As shown, by rotating and installing a push plate at the bottom of the L-shaped toothed plate 28, the L-shaped toothed plate 28 can be moved to drive the push plate of the L-shaped toothed plate 28 to bend, thereby cleaning the surface of the photovoltaic panel 14 in different directions. At the same time, the rubber scraper on the L-shaped toothed plate 28 is designed to be replaceable.

[0027] Specifically, a threaded cylinder 32 is threaded on the outer side of the adjusting screw 31, a slide plate 37 is fixedly installed on the lower surface of the threaded cylinder 32, and an angled collar 33 is fixedly installed on the lower surface of the inner wall of the adjusting screw 31; a fixing ring 35 is provided in the middle of the threaded cylinder 32, the lower surface of the fixing ring 35 is fixedly installed on the slide plate 37, a magnetic socket 36 is provided in the middle of the slide plate 37, the fixing ring 35 is installed on the outer side of the magnetic socket 36, an umbrella-shaped clamping plate 34 is evenly fixedly installed on the upper surface of the fixing ring 35, and an angled block is fixedly installed on the side of the umbrella-shaped clamping plate 34 away from the fixing ring 35. The umbrella-shaped clamping plate 34 is made of plastic material with certain toughness and strength. The lamp holder 15 is located in the middle of the adjusting screw 31, and its bottom is inserted into the magnetic socket 36. By rotating the adjusting screw 31, the angled collar 33 can be driven to initially press the umbrella-shaped clamp 34. Pressing the umbrella-shaped clamp 34 will cause the umbrella-shaped clamp 34 to initially center and fix the surface of the lamp holder 15. Compared with the prior art of installing the lamp holder 15 on the socket by rotating it, this solution can quickly install the lamp holder 15 by rotating the adjusting screw 31. It can not only adapt to different sizes of lamp holders 15, but also accommodate lamp holders of different sizes when the size of the lamp holder 15 and the socket are the same but the size of the top of the socket is different. This solution can not only reduce the danger of the lamp holder 15 cracking due to excessive force when directly rotating it, causing cuts to the operator, but also reduce the electric shock time caused by the internal conductivity of the lamp holder 15.

[0028] Specifically, the upper surface of the sliding rod 38 is fixedly mounted on the sliding plate 37, the tooth surface of the sliding rod 38 meshes with the turbine 39, the middle part of the turbine 39 is rotatably mounted in the replacement chamber 11, the turbine 39 is also meshed with the worm 301, the middle part of the worm 301 is rotatably mounted in the replacement chamber 11, and the end of the worm 301 away from the turbine 39 is fixedly mounted with the rotating wheel 302. In this solution, the rapid replacement mechanism 3 uses a rotating wheel 302, such as... Figure 7 As shown, rotating the wheel 302 can drive the worm gear 301 to drive the turbine 39 to rotate. The rotation of the turbine 39 can drive the sliding rod 38 to move up and down in the replacement chamber 11. The movement of the sliding rod 38 can drive the sliding plate 37 to slide in the replacement chamber 11. When it is necessary to replace the lamp head 15, simply rotate the wheel 302 to drive the sliding plate 37 to slide to the replacement slot opened in the replacement chamber 11, and the lamp head 15 can be quickly replaced, thereby reducing the danger of high-altitude operation for operators.

[0029] Example 2: Warning scenario for nighttime construction on highways; In one section of a highway, road maintenance work will be carried out from 22:00 to 6:00 the next day. Warning posts need to be set up 500 meters before and after the work area. The warning posts need to continuously emit LED flashing lights. Since there is no external power source in the work area, it will rely on photovoltaic power. At the same time, there is a lot of dust on the highway at night, which can easily adhere to the surface of the photovoltaic panels 14. If the light heads 15 malfunction during the work, they need to be replaced quickly to avoid traffic hazards.

[0030] This solution utilizes a self-adjusting and cleaning mechanism for the photovoltaic panel 14: After the device is activated, the controller in the multi-functional self-adjusting cleaning mechanism 2 drives the first control motor 23 to rotate the first rotating gear 22 according to a preset program. This, in turn, engages the inner gear ring 21 to rotate, causing the V-shaped support plate 24 to adjust the orientation of the photovoltaic panel 14 on the substrate 26 according to the movement pattern of moonlight simulating sunlight at night. Simultaneously, a dust monitoring device on the surface of the photovoltaic panel monitors the amount of dust in real time. When the dust thickness exceeds the preset threshold of 0.3mm, the controller immediately activates the spray device 29 to spray water onto the surface of the photovoltaic panel 14. At the same time, it drives the second rotating gear 27 to rotate, engaging the L-shaped scraper 28 to slide on the surface of the photovoltaic panel 14, removing dust through rubber strips. The entire cleaning process takes only 2 minutes, and after cleaning, the light energy conversion efficiency of the photovoltaic panel 14 is restored to over 95% of its initial value.

[0031] Quick replacement of LED head 15: At 3:00 AM during construction, one of the LED heads on a warning post suddenly went out. Workers did not need to climb to the top of the warning post; they simply rotated the wheel 302 on the outside of the replacement chamber 11 from the ground. This caused the worm gear 301 to engage with the turbine 39, which in turn caused the sliding rod 38 to push the sliding plate 37 down to the square replacement slot in the replacement chamber 11. Then, by rotating the adjusting screw 31, the angled collar 33 was released from its pressure on the umbrella canopy clamp 34, allowing the faulty LED head 15 to be removed. The new LED head 15 was then inserted into the magnetic socket 36. The adjusting screw 31 was rotated in the opposite direction, using the angled collar 33 to press the umbrella canopy clamp 34 to secure the new LED head 15. Finally, the wheel 302 was rotated in the opposite direction to reset the sliding plate 37. The entire replacement process took only 1 minute and 30 seconds, with no high-altitude work involved, thus avoiding safety risks.

[0032] In this embodiment, the solution ensures stable photovoltaic power supply at night through the self-cleaning and angle adjustment of the photovoltaic panel 14, avoiding insufficient power supply caused by dust accumulation; the quick lamp head replacement function greatly shortens the fault handling time, reduces the traffic risk of highway night construction, and ensures the safety of workers.

[0033] Example 3: Warning scenario for waterlogged sections of urban roads; Following a heavy rainstorm in a certain city, some low-lying road sections experienced flooding, necessitating the installation of warning posts to alert passing vehicles to detour. These sections have high pedestrian traffic and are prone to accumulating fallen leaves and mud, which could easily cover the photovoltaic panels 14. Furthermore, the flooding could cause short circuits in the lamp holders 15, requiring frequent inspections and replacements. Additionally, the system must be able to operate stably under heavy rain conditions.

[0034] This solution applies the following protection and cleaning methods to the photovoltaic panel 14: During heavy rain, the damper in the multi-functional self-adjusting cleaning mechanism 2 keeps the photovoltaic panel 14 at a 30° tilt angle to prevent rainwater from accumulating on its surface. After the heavy rain, the dust monitoring device detects that the surface of the photovoltaic panel 14 is covered with a mixture of fallen leaves and mud. The controller then activates the spray device 29 to spray water at high pressure. At the same time, the L-shaped scraper 28 drives the auxiliary scraper and pusher to clean the debris from multiple angles along the surface of the photovoltaic panel 14. Because the pusher can bend and rotate, it can thoroughly remove residual debris from the edges and corners of the photovoltaic panel 14. After cleaning, the light transmittance of the photovoltaic panel 14 recovers to 98%, ensuring the light energy collection efficiency on subsequent sunny days.

[0035] Waterproofing and Quick Replacement of Light Heads: Due to rainwater seepage in the flooded section of the road, two warning post light heads (15) experienced short circuit faults. Workers operated the rotating wheel (302) at the roadside, lowering the sliding plate (37) into the replacement slot. Because the umbrella-shaped clamp (34) is made of a tough, waterproof plastic material, and the magnetic socket (36) has a waterproof sealing ring, after removing the faulty light head (15), the new light head (15) can be directly inserted for a waterproof seal without the need for additional waterproof tape. The entire replacement process does not require contact with the water-filled area on top of the warning post, takes only 2 minutes per head, and after replacement, the light head (15) achieves an IP67 waterproof rating, making it suitable for future rainfall.

[0036] Compared to existing solutions, this solution offers several advantages: in heavy rain, the adjustable tilt angle and waterproof design of the photovoltaic panel 14 reduce rain damage to the equipment; the efficient cleaning function of the photovoltaic panel 14 ensures stable power supply in harsh environments; and the quick-replacement and waterproof design of the lamp holder 15 reduces the difficulty and time cost of equipment maintenance in flooded areas.
