Description

Technical Field

[0001] This invention relates to the field of street lighting technology, specifically to an integrated intelligent wind-solar hybrid street light. Background Technology

[0002] Solar-wind hybrid streetlights are streetlights that use both solar and wind power to supply electricity. They are often used in areas where the power grid is difficult to cover.

[0003] However, streetlights installed in remote areas without grid power supply often have larger spacing than those in towns due to sparse population. Therefore, the illumination range of streetlights in remote areas needs to be carefully considered. Streetlights typically illuminate the road surface from above. In this method, the lampshade is small, with less exposed area, making it less susceptible to dust accumulation. This is especially beneficial in remote areas where streetlights are often neglected, allowing them to maintain good brightness over time. However, the disadvantage is that the illumination range is a relatively small, cone-shaped area from top to bottom. A larger illumination range requires taller poles, which makes installation and maintenance more complicated and costly in remote areas. Another type of lighting is similar to a lamppost, where the streetlight shines outwards from a central light source. Compared to the first type, this method provides a wider illumination range and requires less height of the lamppost, making it easier to transport, install, and maintain, and more suitable for remote areas. However, the lampshade of this type has a larger exposed area, making it more susceptible to dust accumulation. Over time, this dust buildup reduces the streetlight's brightness and prevents heat dissipation, potentially causing overheating and damage.

[0004] To address this issue, an integrated intelligent wind-solar hybrid street light is proposed to solve the problem that the lampshade in remote areas is easily covered by dust, which affects the lighting effect. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated intelligent wind-solar hybrid street light, which, by setting a retractable and foldable lampshade, allows the lampshade to automatically fold and retract during the day and extend at night for illumination, thereby solving the problem mentioned in the background art that the lampshade of street lights is not suitable for remote areas.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An integrated intelligent wind-solar hybrid street light includes a light pole with a lampshade mounted on it. A light source is housed inside the lampshade. The light pole also features a solar power generation component and a wind power generation component, which together supply power to the light source. The lampshade comprises a top cover, a bottom cover, and side covers. The top cover is made of metal and is fixedly connected to the light pole.

[0007] The side cover is cylindrical and made of soft silicone material, with a light transmittance of 85%-90%. The soft silicone material allows for easy folding and storage, preventing large areas of the side cover from being exposed to the air and attracting dust when the streetlights are not in use.

[0008] The side cover has a wavy corrugated section, which gives the side cover a bellows-like shape, allowing it to deform in a specific direction when folded up, making it easy to determine the shape of the side cover after folding. In addition, a rigid upper connecting ring is fixedly installed on the top of the side cover, and a rigid lower connecting ring is fixedly installed on the bottom of the side cover. Both the upper and lower connecting rings are threaded on their outer sides. The upper connecting ring is fixedly connected to the top cover by the thread, and the lower connecting ring is fixedly connected to the bottom cover by the thread. The top cover, bottom cover, and side cover together form a sealed lighting cavity, and the light source is located inside the lighting cavity.

[0009] A first connecting rod is rotatably mounted on the top cover. The first connecting rod can swing up and down along the axis of the lamp cover. A second connecting rod is rotatably mounted on the free end of the first connecting rod. The other end of the second connecting rod is hinged to the bottom cover. A micro motor for controlling the rotation of the first connecting rod is provided on the top cover. The micro motor is electrically connected to the solar power generation module and the wind power generation module.

[0010] The lampshade is divided into a top cover, side covers, and a bottom cover. The side covers are made of a soft material and have corrugated sections. Finally, a first and second connecting rod are used. When a micro-motor drives the first connecting rod downwards, it pushes the second connecting rod, which in turn pushes the bottom cover downwards away from the top cover. The corrugated sections on the side covers are stretched downwards. When the first and second connecting rods are vertical, the side covers are stretched to their maximum extent. At this point, when the light source illuminates from inside the lighting cavity, the light can shine in all directions, providing the largest possible illuminated area for the environment.

[0011] When the streetlight does not need to illuminate the environment, the micro motor drives the first connecting rod to rotate upwards. Simultaneously, the first connecting rod pulls the second connecting rod, which in turn pulls the base cover upwards. As the base cover moves upwards, the corrugated section folds, reducing the area of ​​the side cover exposed to the external environment. This effectively prevents external dust from adhering to the side cover, avoiding a decrease in light transmittance due to dust accumulation over long-term use, thus ensuring the streetlight's illumination range. Simultaneously, it also prevents dust adhesion from affecting the lamp cover's heat dissipation, thereby extending the lifespan of the side cover.

[0012] Preferably, the bottom cover is provided with a support ring, and the support ring has multiple arc-shaped grooves along the axial direction of the side cover. The multiple arc-shaped grooves are evenly distributed on the support ring with the axial direction of the side cover as the reference. The top cover is detachably connected with one or more limiting posts by threads. The limiting posts are used to insert into the arc-shaped grooves to limit the horizontal displacement of the bottom cover.

[0013] By incorporating a limiting post and an arc-shaped groove, the limiting post is inserted into the arc-shaped groove. This ensures that when the first and second connecting rods move the bottom cover up and down, the bottom cover moves along the axis of the side cover without tilting. This ensures that the side cover can fold along its axis, further improving the stability of the side cover when folded and stored. It also minimizes the area of ​​the stored side cover exposed to the environment, further preventing dust from adhering to the side cover.

[0014] In addition, the limiting posts provide further support for the side cover when it is deployed, preventing it from swaying and being pulled by the wind and avoiding damage to the soft side cover.

[0015] Preferably, the bottom cover is made of rigid transparent plastic, and a shielding sleeve is fixedly installed on the top cover. The shielding sleeve is made of non-ferromagnetic metal. When the first connecting rod moves upward and the top of the support ring abuts against the bottom of the shielding sleeve, the side cover is stored in the shielding sleeve.

[0016] When the light source is not emitting light, the side cover is housed inside the shielding sleeve, further isolating it from the external space and preventing dust from accumulating on it after prolonged use. Simultaneously, the side cover is made of metal, effectively blocking sunlight when not in use and preventing it from aging and failing due to prolonged exposure. The transparent base cover allows the streetlight to radiate light in more directions during illumination, further increasing its lighting range.

[0017] Preferably, a photosensitive sensor for detecting weather brightness is provided on the top of the top cover. The photosensitive sensor is electrically connected to a light source. A limiting groove is formed on the side of the top cover. A rotating shaft is horizontally rotatably installed inside the limiting groove. A limiting block is fixedly installed on the rotating shaft. The first connecting rod is slidably installed on the rotating shaft. The limiting block restricts the relative rotation between the first connecting rod and the rotating shaft. The output end of the micro motor is fixedly connected to the rotating shaft. Pressure sensors are provided on both sides of the limiting groove. The left and right sides of the first connecting rod abut against the two pressure sensors respectively. The pressure sensors are electrically connected to the micro motor. A wind detection plate is fixedly installed on the first connecting rod.

[0018] The installation of photosensors enables streetlights to automatically sense changes in the weather, allowing them to turn on automatically at night and turn off automatically during the day without manual control.

[0019] Meanwhile, by fixing a wind detection plate to the first connecting rod and installing pressure sensors on both sides of the first connecting rod, and by setting the detection value of the pressure sensors, when the detected value exceeds the set value, a signal is fed back to the micro motor. The micro motor then controls the first connecting rod and drives the side cover to fold back into the shielding sleeve, allowing the light source to illuminate through the bottom cover. Because the side cover is made of soft material, it is easily damaged by wind force and debris blown by the wind. For streetlights in remote areas, long-term use and reduced maintenance and replacement frequency are important considerations. Therefore, although the illumination range of the streetlight is smaller compared to when the side cover is unfolded, it automatically protects the streetlight in strong winds, preventing damage. This improves the intelligence level of the streetlight and effectively guarantees its service life.

[0020] Preferably, a locking ring is fixedly installed on the support ring, the inner diameter of the locking ring is the same as the outer diameter of the shielding sleeve, a locking groove is horizontally opened on the shielding sleeve, a locking block is slidably installed inside the locking groove, a guide ramp is provided on the lower side of the end of the locking block that extends out of the locking groove, a locking spring is provided inside the locking groove for pushing the locking block horizontally out of the locking groove, and an electromagnet is also provided inside the locking groove for attracting the locking block into the locking groove.

[0021] When the bottom cover moves upward, the locking ring presses upward against the guide ramp and pushes the locking block into the locking groove, causing the locking block to avoid the locking ring. When the locking ring passes the locking block, the locking spring pushes the locking block out and resets. At this point, under the limit of the locking block, the locking ring can no longer move downward, which helps to further improve the stability of the side cover when folded and retracted, reduces the stress on the micro motor, and helps to ensure the service life of the micro motor. When it is necessary to unfold the side cover, the electromagnet is energized and activated. The electromagnet attracts the locking block into the locking groove, allowing the locking ring to pass over the locking block and avoiding interference between the locking block and the locking ring.

[0022] Preferably, a humidity sensor is fixedly installed on the top cover, the humidity sensor is located inside the lighting cavity, and a warning light is also installed on the top cover, the warning light being electrically connected to the humidity sensor.

[0023] Because streetlights are installed at long intervals in remote areas, each maintenance requires a lot of manpower. In addition, because the side covers are made of soft silicone material, they are prone to aging and damage after long-term use.

[0024] By installing a humidity sensor to detect the humidity inside the lighting cavity, when the humidity detected by the sensor exceeds a set value, the sensor sends a signal to the warning light, which then illuminates, making it easier for maintenance personnel to identify and replace the light promptly. This reduces the complexity of street light maintenance; maintenance personnel only need to occasionally check if the warning light is on to determine if the side cover needs replacement, facilitating street light inspection and maintenance in unoccupied areas.

[0025] Preferably, the upper side of the shielding sleeve is provided with multiple vent holes, each of which penetrates the side wall of the shielding sleeve and is inclined downward. The multiple vent holes are evenly distributed on the shielding sleeve with the axis of the shielding sleeve as the reference.

[0026] When streetlights are illuminated, dew and rainwater easily adhere to the side covers. When the streetlights are not illuminating, the side covers are retracted into the protective sleeve. If the external temperature rises, the dew and rainwater will evaporate inside the protective sleeve, forming water vapor. Because the support ring is pressed against the bottom of the protective sleeve, the water vapor cannot escape from the sleeve, easily creating a high-temperature and high-humidity environment inside the sleeve. This can lead to rapid aging of the side covers, and consequently, moisture entering the lighting cavity, causing damage to the circuitry due to dampness. By installing vents, rainwater and dew can quickly evaporate and escape from the protective sleeve, slowing down the aging process of the side covers and helping to extend their service life.

[0027] Preferably, the bottom of the shielding sleeve is provided with a plurality of drainage grooves, each of which penetrates the side wall of the shielding sleeve, and the plurality of drainage grooves are evenly distributed on the shielding sleeve around the axis of the shielding sleeve.

[0028] The drainage channels help allow dew and rainwater adhering to the side cover to flow out of the shield sleeve more quickly.

[0029] Preferably, multiple deformable springs are vertically arranged on the support ring. The deformable springs are made of a two-way shape memory alloy. Each deformable spring has a rubber cleaning block on its top. The cleaning blocks abut against the outer wall of the side cover. When the deformable spring is above the phase change temperature, the deformable spring becomes straight and pushes the cleaning block upward. When the deformable spring is below the phase change temperature, the deformable spring curls downward and returns to its spring shape, pulling the cleaning block downward.

[0030] By utilizing natural temperature variations and selecting the phase transition temperature of the deformable spring based on the temperature difference between day and night, the spring can automatically deform daily. Each time the spring deforms, a cleaning block scrapes the side cover, automatically cleaning it. Replacing traditional drive mechanisms with deformable springs saves production costs and installation space, ensuring the miniaturization of streetlights and facilitating transportation and installation in remote areas. Furthermore, relying solely on natural temperature changes enhances the streetlight's self-cleaning ability, further reducing control costs and ensuring the cover's performance and lifespan, making it more suitable for maintenance-free remote areas.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The integrated intelligent wind-solar hybrid street light designed in this invention uses a lamp cover consisting of a top cover, side covers, and a bottom cover. When the street light is illuminating, the side covers extend and emit light from the light source inside the side covers, effectively increasing the illumination range of the street light. When the street light is not illuminating, the side covers are folded and stored inside the shielding sleeve to prevent dust from adhering to the side covers and affecting the lighting effect. This new lighting method is more suitable for street lighting in remote areas.

[0032] 2. The integrated intelligent wind-solar hybrid street light designed in this invention is also equipped with a pressure sensor and a wind detection plate on the first link. By increasing the force-bearing area of ​​the first link through the wind detection plate, the first link can sense the strength of the wind. When the first link is subjected to wind resistance, the first link squeezes the pressure sensor. When the value detected by the pressure sensor is greater than the set value, the micro motor controls the first link to retract the side cover to avoid damage to the side cover due to strong winds.

[0033] 3. The integrated intelligent wind-solar hybrid street light designed in this invention is also equipped with a deformable spring and a cleaning block. The deformable spring is made of a two-way shape memory alloy. Utilizing the temperature changes in the natural environment, when the deformable spring deforms due to temperature, the cleaning block will scrape and clean the side cover, improving the self-cleaning ability of the street light and further ensuring the service life of the side cover.

[0036] Please see Figures 1 to 9 This invention provides an integrated intelligent wind-solar hybrid street light, the technical solution of which is as follows: An integrated intelligent wind-solar hybrid street light, reference Figures 1 to 3The streetlight uses a microcontroller chip as its control system. The streetlight includes a pole 1, a lampshade 2 mounted on the pole 1, and a light source 3 inside the lampshade 2. The light source 3 can be a halogen bulb or an LED bulb, selected according to usage requirements. The pole 1 also has a solar power generation component 4 and a wind power generation component 5. The solar power generation component 4 and the wind power generation component 5 work together to power the light source 3. The electricity generated by the wind power generation component 5 and the solar power generation component 4 can be stored in a battery before being output to power the light source 3. Since the application of the wind power generation component 5 and the solar power generation component 4 in the streetlight field is already quite mature and belongs to conventional existing technology, and this invention mainly involves improvements to the lampshade 2, without involving improvements to the wind power generation component 5 and the solar power generation component 4, this embodiment will not elaborate further.

[0037] refer to Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 In this invention, the lampshade 2 includes a top cover 201, a bottom cover 202, and a side cover 203. The top cover 201 is made of metal and is fixedly connected to the lamp post 1. The bottom cover 202 is made of rigid transparent plastic and has a support ring 13. Multiple arc-shaped grooves 14 are formed on the support ring 13 along the axial direction of the side cover 203, and these grooves are evenly distributed around the axis of the side cover 203. The top cover 201 is also threadedly and detachably connected to one or more limiting posts 15 for engaging with the arc-shaped grooves 14.

[0038] In addition, refer to Figure 3 , Figure 6 as well as Figure 9 The side cover 203 is cylindrical and made of soft silicone material. The light transmittance of the side cover 203 needs to reach 85%-90%. The side cover 203 has a wavy corrugated section 6, which forms a bellows-like shape, allowing it to deform in a specific direction when folded up, making it easier to determine the folded shape. Furthermore, a rigid upper connecting ring 7 is fixedly installed on the top of the side cover 203, and a rigid lower connecting ring 8 is fixedly installed on the bottom. Both the upper and lower connecting rings 7 and 8 have threads on their outer sides. The upper connecting ring 7 is fixedly connected to the top cover 201 via the threads, and the lower connecting ring 8 is fixedly connected to the bottom cover 202 via the threads. The top cover 201, bottom cover 202, and side cover 203 together form a sealed lighting cavity 9, and the light source 3 is located inside the lighting cavity 9.

[0039] refer to Figure 1 , Figure 3 and Figure 7A shielding sleeve 16 is also fixedly installed on the top cover 201. The shielding sleeve 16 is made of non-ferromagnetic metal. When the top of the support ring 13 abuts against the bottom of the shielding sleeve 16, the side cover 203 is stored in the shielding sleeve 16.

[0040] refer to Figure 6 and Figure 8 Two deformable springs 32 are vertically mounted on the support ring 13. These two springs are evenly distributed around the axis of the shielding sleeve 16, and are made of a two-way shape memory alloy. Each deformable spring 32 has a rubber cleaning block 33 at its top. The cleaning block 33 is arc-shaped, and the two cleaning blocks 33 form a complete circle, coaxial with the side cover 203. When the side cover 203 is fully extended, both cleaning blocks 33 abut against the outer wall of the side cover 203. When the deformable spring 32 is above the phase change temperature, it straightens and pushes the cleaning block 33 upwards. When the deformable spring 32 is below the phase change temperature, it curls downwards to return to its spring shape and pulls the cleaning block 33 downwards.

[0041] The phase transition temperature of the deformable spring 32 is set within the range of 25℃ to 28℃. This is because summer and winter temperatures vary. In summer, daytime temperatures easily exceed this range, and at night, except in a few southern regions, temperatures in most areas tend to drop below this range. Furthermore, in winter, under direct sunlight, most areas, except for a few northern regions, easily reach a phase transition temperature of 25℃. Therefore, 25℃ to 28℃ is a suitable temperature range for most parts of the country, ensuring that the deformable spring 32 deforms at least once a day, allowing for daily scraping and cleaning of the side cover 203. In this embodiment, 25℃ is chosen as the phase transition temperature of the deformable spring 32. Of course, the phase transition temperature can be set to other temperatures according to actual needs.

[0042] refer to Figure 3 and Figure 7 A humidity sensor 28 is also fixedly installed on the top cover 201. The humidity sensor 28 is located inside the lighting cavity 9. A warning light 29 is also installed on the top cover 201. The warning light 29 is electrically connected to the humidity sensor 28.

[0043] In addition, refer to Figure 7 The upper side of the shielding sleeve 16 has multiple vent holes 30, each of which penetrates the side wall of the shielding sleeve 16 and is inclined downwards. The multiple vent holes 30 are evenly distributed around the axis of the shielding sleeve 16. The bottom of the shielding sleeve 16 has multiple drainage grooves 31, each of which penetrates the side wall of the shielding sleeve 16 and is evenly distributed around the axis of the shielding sleeve 16.

[0044] refer to Figure 1 and Figure 2 as well as Figure 5 The top of the top cover 201 is also equipped with a photosensitive sensor 17 for detecting weather brightness. The photosensitive sensor 17 is electrically connected to the light source 3. A limiting groove 18 is formed on the side of the top cover 201. A rotating shaft 19 is horizontally rotatably mounted inside the limiting groove 18. A limiting block 20 is fixedly mounted on the rotating shaft 19. A first connecting rod 10 is rotatably mounted inside the limiting groove 18. The first connecting rod 10 is slidably mounted on the rotating shaft 19. The limiting block 20 restricts the relative rotation between the first connecting rod 10 and the rotating shaft 19.

[0045] refer to Figure 3 and Figure 4 A micro motor 12 is installed on the top cover 201. The output end of the micro motor 12 is fixedly connected to the rotating shaft 19 to drive the rotating shaft 19 to rotate. Pressure sensors 21 are provided on both sides of the limiting groove 18. The left and right sides of the first connecting rod 10 abut against the two pressure sensors 21 respectively. The pressure sensors 21 are electrically connected to the micro motor 12. A detection wind plate 22 is fixedly installed on the first connecting rod 10. A second connecting rod 11 is rotatably installed on the free end of the first connecting rod 10. The other end of the second connecting rod 11 is hinged to the bottom cover 202. A micro motor 12 for controlling the rotation of the first connecting rod 10 is provided on the top cover 201. The micro motor 12 is electrically connected to the solar power generation component 4 and the wind power generation component 5.

[0046] In addition, refer to Figure 6 and Figure 8 A locking ring 23 is fixedly installed on the support ring 13. The inner diameter of the locking ring 23 is the same as the outer diameter of the shielding sleeve 16. A locking groove 24 is horizontally opened on the shielding sleeve 16. A locking block 25 is slidably installed inside the locking groove 24. A guide ramp 26 is provided on the lower side of the end of the locking block 25 that extends out of the locking groove 24. A locking spring 34 is provided inside the locking groove 24 for pushing the locking block 25 horizontally out of the locking groove 24. An electromagnet 27 is also provided inside the locking groove 24 for attracting the locking block 25 into the locking groove 24.

[0047] When using, refer to Figure 1 and Figure 3 The photosensitive sensor 17 constantly detects the brightness of the surrounding environment. When the brightness of the surrounding environment is higher than the set value of the photosensitive sensor 17, the microcontroller control system of the street light determines that it is daytime, the light source 3 is not turned on, the motor does not operate, and the side cover 203 is folded and stored inside the shielding sleeve 16. At this time, the locking ring 23 is located above the locking block 25 and abuts against the locking block 25, and the top of the support ring 13 abuts against the bottom of the shielding sleeve 16.

[0048] As the sun sets, (reference) Figure 3 , Figure 6 and Figure 7 When the photosensitive sensor 17 detects that the ambient brightness is lower than the set value, the microcontroller control system of the street light determines that it is already dark. Subsequently, the light source 3 is powered on and illuminates, and the electromagnet 27 is also powered on to generate magnetic force. The electromagnet 27 attracts the locking block 25 into the locking groove 24, and the locking block 25 no longer obstructs the downward movement of the locking ring 23, compressing the locking spring 34. Then, the micro motor 12 controls the first connecting rod 10 to rotate downward. When the first connecting rod 10 rotates downward, it pushes the second connecting rod 11 to move downward. The second connecting rod 11 then pushes the bottom cover 202 and the supporting ring 13 to move downward. As the bottom cover 202 and the supporting ring 13 move downward, the side cover 203 is pulled out from inside the shielding sleeve 16 and is continuously unfolded. When the first connecting rod 10 and the second connecting rod 11 rotate downward and are both in a vertical state, the bottom cover 202 moves to its limit position. At this point, the side cover 203 is fully extended, the micro motor 12 stops rotating, the electromagnet 27 is de-energized, and the locking block 25 extends out of the locking groove 24 again under the elastic force of the locking spring 34. Since the side cover 203 is fully extended, the light emitted from the light source 3 from inside the side cover 203 can shine in all directions, giving the streetlight a wider illumination range, rather than just a cone-shaped downward beam from the bottom cover 202.

[0049] When the side cover 203 is deployed, refer to Figures 2 to 6 In windy weather, the wind will blow the detection wind plate 22 on the first connecting rod 10. After being blown by the wind, the detection wind plate 22 will squeeze one of the pressure sensors 21 on the left and right sides. The detection value of the pressure sensor 21 can be set, such as 2N. When one of the pressure sensors 21 detects a pressure greater than the set value, it will send a signal to the micro motor 12. The micro motor 12 will drive the first connecting rod 10 and the second connecting rod 11 to reset upwards and pull the bottom cover 202 to reset upwards, and fold the side cover 203 back into the shielding sleeve 16. When the locking ring 23 moves upwards and passes the locking block 25, the locking ring 23 squeezes the guide ramp 26 on the locking block 25, squeezing the locking block 25 towards the inside of the locking ring 23. In this way, it can pass over the locking block 25 and reach above the locking block 25.

[0050] If the photosensor 17 still determines that it is nighttime, the light source 3 will remain powered on and lit. The pressure sensor 21 will continue to detect the pressure. If the pressure continues to exceed the set value, the streetlight can maintain the state where the side cover 203 is folded inside the shielding sleeve 16 for illumination. At this time, the light shines downwards in a cone-shaped area through the bottom cover 202. Although the illumination range is reduced, it effectively prevents the side cover 203 from being damaged by strong winds.

[0051] When the pressure sensor 21 detects that the pressure is less than the set value, the above steps are repeated to unfold the side cover 203 for illumination until the wind returns or the photosensitive sensor 17 determines that the environment is in daylight. Then the micro motor 12 drives the first link 10 and the second link 11 to retract the side cover 203 into the shielding sleeve 16.

[0052] In addition, refer to Figure 6 and Figure 8 When the streetlights are in use, during the daytime, if the ambient temperature is higher than the phase transition temperature of the deformable spring 32, the side cover 203 is folded and stored inside the shielding sleeve 16. The deformable spring 32 deforms from a bent spring shape to a vertical state. When the deformable spring 32 returns to a vertical state, the cleaning block 33 moves upward along with the deformed spring 32 and continuously pushes the folded side cover 203. The folded side cover 203 vibrates after being pushed, shaking off the dew, rainwater, or dust that adhered to it at night.

[0053] At night, refer to Figure 6 and Figure 8 As the side cover 203 unfolds, the temperature gradually decreases at night. When the ambient temperature is lower than the phase change temperature of the deformation spring 32, the deformation spring 32 re-deforms into a bent state and pulls the cleaning block 33 downward. Since the side cover 203 is fully unfolded at this time, the cleaning block 33 is completely in contact with the outer wall of the side cover 203. When the cleaning block 33 moves downward, it scrapes the outer wall of the side cover 203, automatically cleaning the side cover 203 again, effectively reducing the dust adhering to the side cover 203.

[0054] At the same time, refer to Figure 7 When dew or rainwater adheres to the side cover 203 at night, the moisture evaporates between the side cover 203 and the shielding sleeve 16 after the sun comes out and the temperature rises during the day. The evaporated water vapor can be discharged through the vent 30 at the top of the side cover 203. Rainwater or dew that forms water droplets can also be discharged through the drainage groove 31 at the bottom of the side cover 203.

[0055] In addition, refer to Figure 3 and Figure 8 The lighting cavity 9 is also equipped with a humidity sensor 28. The humidity sensor 28 is responsible for detecting the humidity inside the lighting cavity 9, and then detecting whether the side cover 203 is aging and cracked. If the value detected by the humidity sensor 28 is higher than the set value, the warning light 29 will be turned on to make it easier for maintenance personnel to notice the street light damage.

[0056] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
