Description

Technical Field

[0001] This invention relates to the field of smart street light technology, specifically a multifunctional adjustable smart street light for urban roads. Background Technology

[0002] Smart streetlights will be based on road lighting poles, integrating public security, traffic signals, communications, and traffic signs into one, achieving multi-pole integration, reducing roadside poles, and freeing up public space resources. At the same time, as an important carrier for smart city construction, smart streetlights will serve as a port for the Internet of Things, playing a greater "integrated" role. As the most densely and evenly distributed information infrastructure in the city, streetlight poles are considered to be a superior carrier for outdoor coverage of 5G base stations. Driven by the construction of smart cities and 5G base stations, they will gradually transform from a single lighting function into a new type of public infrastructure.

[0003] Chinese invention patent 2021106068544 discloses a smart street light in the field of smart city technology, including a main pole, a rotating ring, a cylindrical multimedia display screen, and a rotating lighting lamp. A fixed base is provided at the bottom of the main pole. A control box, multiple types of charging piles, a multimedia frame, and the rotating ring are sequentially arranged on the outer wall of the main pole above the fixed base. The cylindrical multimedia display screen is mounted on the multimedia frame. An environmental monitoring sensor box is provided at the top of the main pole. Although this device meets the user's needs to a certain extent, it still has certain shortcomings during use. Specific problems are as follows:

[0004] The streetlight has a single function and is inconvenient to adjust. When people need to inspect the streetlight, they need to use climbing tools to do so, which poses a safety hazard. In addition, the illumination angle is fixed and cannot be adjusted when a certain area needs to be illuminated at night. Moreover, the streetlight is often exposed to the elements, which can easily cause fogging and corrosion on the surface due to weather conditions, affecting its service life.

[0005] At the same time, since the light intensity produced by the existing street light devices is fixed, adjusting the height of the street light will simultaneously change the illumination range of the street light on the ground, thereby correspondingly changing the light intensity of the street light on the road surface and reducing the safety of pedestrians or vehicles.

[0006] When the angle of a street light is adjusted, the tilt angle of the street light and the reflector changes simultaneously, causing the light to shine obliquely onto the ground. This not only reduces the brightness of the street light on the road surface, but also causes the oblique light to shine directly on pedestrians or vehicles, potentially leading to safety accidents.

[0007] Finally, the existing devices all lack shock absorption and buffering devices for the reflector. Therefore, when encountering strong winds or earthquakes, the reflector will shake, which will not only cause the light on the surrounding road surface to sway, reducing the safety of pedestrians or vehicles, but also cause the device to tip over when the shaking amplitude is too large, thereby damaging the street light. Furthermore, the tipped device will threaten the safety of pedestrians or vehicles in a large surrounding area. Summary of the Invention

Implementation

[0033] 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. Example

[0034] Please see Figure 1-5This is the first embodiment of the present invention. This embodiment provides a multifunctional adjustable smart street light for urban roads, including a base 1. A controller is provided on one side of the base 1. The controller electrically controls various electrical components. Anchor screws 8 are threaded around the inner surface of the base 1. A height adjustment mechanism 9 is provided at the top center of the base 1. A connecting plate 2 is slidably connected to the top of the height adjustment mechanism 9. Therefore, when the height adjustment mechanism 9 is activated, it can drive the connecting plate 2 to move up and down.

[0035] The height adjustment mechanism 9 includes a transmission box 901, a drive motor 902, a driving bevel gear 903, a driven bevel gear 904, a threaded sleeve 905, a fixing plate 906, a side groove 907, a support rod 908, a through hole 909, a limit block 910, and a threaded rod 911. The transmission box 901 is fixedly installed on the top of the base 1, the drive motor 902 is fixedly installed on the bottom side of the transmission box 901, the driving bevel gear 903 is fixedly connected to the output end of the drive motor 902, the threaded rod 911 is movably connected to the bottom of the inner cavity of the transmission box 901 through a bearing, and the driven bevel gear 904 is fixedly connected to the bottom of the outer surface of the threaded rod 911. The driven bevel gear 904 and the driving bevel gear 903 are driven by tooth meshing. When the drive motor 902 starts, it drives the driving bevel gear 903 to rotate. The rotation of the driving bevel gear 903 drives the threaded rod 911 to rotate through tooth meshing with the driven bevel gear 904.

[0036] The threaded sleeve 905 is threadedly connected to the outer surface of the threaded rod 911. The fixing plate 906 is fixedly connected to both sides of the threaded sleeve 905. The support rod 908 is fixedly connected to the top of the fixing plate 906. The through hole 909 is opened on both sides of the top of the transmission box 901. The top of the support rod 908 passes through the inner cavity of the through hole 909 and extends to the top of the transmission box 901. By setting the through hole 909, the support rod 908 can be limited to prevent it from shifting. The top of the support rod 908 is fixedly connected to the bottom of the connecting plate 2. Therefore, when the threaded rod 911 rotates, it drives the threaded sleeve 905 to move up and down through the threaded engagement with the threaded sleeve 905. When the threaded sleeve 905 moves up and down, it drives the support rod 908 to move up and down through the fixing plates 906 on both sides. When the support rod 908 moves up and down, it drives the connecting plate 2 at the top to move up and down along the through hole 909, thereby realizing the height adjustment of the connecting plate 2.

[0037] The limiting block 910 is fixedly connected to the top of the threaded rod 911, and the diameter of the limiting block 910 is larger than the diameter of the threaded sleeve 905. By setting the limiting block 910, the threaded sleeve 905 can be limited, preventing the limiting block 910 from falling off. The side groove 907 is opened on both sides of the inner wall of the transmission box 901. The outer side of the fixing plate 906 is slidably connected to the inner cavity of the side groove 907. By setting the side groove 907, the stability of the fixing plate 906 during movement can be improved. The bottom side of the transmission box 901 and the outer side of the drive motor 902 are provided with a protective cover 7, and the protective cover 7 is connected to the inner surface of the transmission box 901 by bolts and threads. By setting the protective cover 7, the drive motor 902 can be protected and prevented from being corroded by rainwater.

[0038] In use, the controller controls the output of the drive motor 902 to drive the active bevel gear 903 to rotate. The active bevel gear 903 drives the driven bevel gear 904 to rotate through tooth meshing. The driven bevel gear 904 drives the threaded rod 911 to rotate. The threaded rod 911 drives the threaded sleeve 905 to rotate upward through thread transmission. The threaded sleeve 905 drives the fixed plate 906 to slide upward along the inner cavity of the side groove 907. The fixed plate 906 drives the connecting plate 2 to move upward through the support rod 908. When maintenance is required, the output of the drive motor 902 drives the active bevel gear 903 to rotate in the opposite direction, causing the connecting plate 2 to fall, thus facilitating maintenance and avoiding safety hazards caused by people climbing.

[0039] The top of the connecting plate 2 is provided with an angle adjustment mechanism 3. The angle adjustment mechanism 3 includes an adjustment box 301, an arc plate 302, a sliding block 303, a sliding groove 304, a gear ring 305, a gear 306, a rotating shaft 307, a connecting rod 308, a limiting groove 309, and a servo motor 310. The bottom of the adjustment box 301 is fixedly connected to the top of the connecting plate 2. The servo motor 310 is fixedly connected to one side of the adjustment box 301. The rotating shaft 307 is fixedly connected to the output end of the servo motor 310. The gear 306 is fixedly connected to the middle of the outer surface of the rotating shaft 307. The inner side of the gear ring 305 meshes with the outer surface of the gear 306. The connecting rod 308 is fixedly connected to the top of the gear ring 305. The controller controls the servo motor 310 to start and drive the rotating shaft 307 to rotate. The rotation of the rotating shaft 307 drives the gear 306 to rotate. The rotation of the gear 306 drives the gear ring 305 to rotate. The rotation of the gear ring 305 drives the connecting rod 308 to rotate.

[0040] A limiting groove 309 is formed at the top of the regulating box 301. The top of the connecting rod 308 passes through the inner cavity of the limiting groove 309 and extends to the top of the regulating box 301. By setting the limiting groove 309, the connecting rod 308 can be limited to prevent it from shifting during movement. The arc plate 302 is fixedly connected to the bottom of the inner cavity of the regulating box 301. The sliding groove 304 is formed at the top of the arc plate 302. The sliding block 303 is fixedly connected to the bottom middle of the gear ring 305, and the sliding block 303 is slidably connected in the inner cavity of the sliding groove 304. By setting the sliding block 303 and the sliding groove 304, the stability of the gear ring 305 during rotation can be improved.

[0041] A protective cover 4 is provided on one side of the regulating box 301 and outside the servo motor 310. The protective cover 4 is connected to the inner surface of the regulating box 301 by bolts and threads. By setting the protective cover 4, the servo motor 310 can be protected and the service life of the servo motor 310 can be improved.

[0042] In use, the controller controls the output of the servo motor 310 to drive the rotating shaft 307 to rotate. The rotating shaft 307 drives the gear 306 to rotate. The gear 306 drives the gear ring 305 to rotate through the meshing of the teeth. The gear ring 305 drives the connecting rod 308 to swing, thereby enabling focused lighting for certain specific areas.

[0043] The top of the angle adjustment mechanism 3 is rotatably connected to the mounting mechanism 5, and the top of the mounting mechanism 5 is provided with an elastic reflector 6.

[0044] The mounting mechanism 5 includes a mounting base 501. The bottom of the mounting base 501 is fixedly connected to the top of the connecting rod 308. When the connecting rod 308 rotates, it synchronously drives the mounting base 501 to rotate. The mounting base 501 has pre-drilled slots 509 on both sides of its interior. The top and bottom of each pre-drilled slot 509 have sliding grooves 510. An electromagnetic sliding plate 505 is slidably connected inside the sliding groove 510. A pull rod 507 is located at the central axis of the electromagnetic sliding plate 505. The electromagnetic sliding plate 505 slides within the pre-drilled slot 509 by being limited by the sliding groove 510, thereby driving the pull rod 507 to slide synchronously within the pre-drilled slot 509. Two sets of slots 511 are symmetrically opened on the top of the mounting base 501. A block 503 is slidably connected inside the slot 511. Each block 503 has a slot 504 on the side near the pull rod 507. The slot 504 matches the pull rod 507, so the pull rod 507 can be inserted into the slot 504 and limit the position of the block 503. The top of the two sets of blocks 503 is hinged to the bottom sides of the elastic reflector 6. The elastic reflector 6 is limited by the position of the block 503 inside the slot 511. The street lamp body 10 is provided at the top center of the mounting base 501. The street lamp body 10 generates light to illuminate the surrounding environment.

[0045] The reserved slots 509 are provided on the left and right sides of the mounting base 501, and the outer side of the pull rod 507 passes through the inner cavity of the reserved slots 509 and extends to the outer side of the mounting base 501. By setting the reserved slots 509, the pull rod 507 can be limited to prevent it from shifting. The reserved slots 509 and the slots 511 are connected to each other through the transverse holes 508. The transverse holes 508 are slidably connected to the outer surface of the pull rod 507. By setting the transverse holes 508, the pull rod 507 can be limited to prevent it from shifting during movement. Multiple sets of connecting springs 506 are evenly arranged on the side of the electromagnetic slide plate 505 near the magnetic ring 502. The other side of the connecting springs 506 is fixedly connected to the side wall of the reserved slots 509. The connecting springs 506 enable the electromagnetic slide plate 505 to slide and reset inside the reserved slots 509.

[0046] In use, first pull the lever 507 outward to drive the electromagnetic slide plate 505 to slide outward along the inner cavity of the slide groove 510. The electromagnetic slide plate 505 squeezes the connecting spring 506 and moves outward. At this time, the connecting spring 506 deforms due to the force. Then, the locking block 503 is locked into the inner cavity of the locking slot 511. After that, release the lever 507. Under the action of its own elastic force, the connecting spring 506 drives the electromagnetic slide plate 505 to move inward. The electromagnetic slide plate 505 drives the lever 507 to insert into the inner cavity of the slot 504 to limit the locking block 503, thus completing the installation of the elastic reflector 6. By setting the elastic reflector 6, the street lamp body 10 can be protected to avoid fogging and corrosion on the surface of the street lamp due to weather conditions, which would affect its service life.

[0047] When the height of the street light body 10 needs to be adjusted, the controller controls the output of the drive motor 902 to drive the active bevel gear 903 to rotate. The active bevel gear 903 drives the driven bevel gear 904 to rotate through tooth meshing. The driven bevel gear 904 drives the threaded rod 911 to rotate. The threaded rod 911 drives the threaded sleeve 905 to rotate upward through thread transmission. The threaded sleeve 905 drives the fixing plate 906 to slide upward along the inner cavity of the side groove 907. The fixing plate 906 drives the connecting plate 2 to move upward through the support rod 908. The connecting plate 2 causes the height of the street light body 10 to change, making the street light body 10 rise. When the street light body 10 needs to be inspected, the output of the drive motor 902 drives the active bevel gear 903 to rotate in the opposite direction, making the street light body 10 lower, which is convenient for people to inspect and avoids people climbing and causing safety hazards.

[0048] When it is necessary to adjust the angle of the street lamp body 10, the output end of the servo motor 310 drives the rotating shaft 307 to rotate. The rotating shaft 307 drives the gear 306 to rotate. The gear 306 drives the gear ring 305 to rotate through the meshing of the teeth. The gear ring 305 drives the connecting rod 308 to swing. The connecting rod 308 causes the angle of the street lamp body 10 to change, which can adjust the illumination angle of the street lamp body 10 and thus provide focused lighting for certain specific areas.

[0049] This device enables the adjustment function of smart streetlights. It can not only adjust the height of the streetlight body 10, but also adjust its rotation angle, thereby increasing the lighting range and improving the lighting accuracy. It is also easy to install and disassemble, simple and efficient to operate, and has a good limiting and fixing effect. Example

[0050] Please see Figure 6 As can be seen from the first embodiment, when the height adjustment mechanism 9 adjusts the height of the street lamp body 10, since the light intensity generated by the street lamp body 10 is constant, the range of light illuminating the road surface after reflection by the elastic reflector 6 increases with the increase of the height of the street lamp body 10, and the brightness of the road surface decreases accordingly; while when the angle adjustment mechanism 3 causes the angle of the street lamp body 10 to change, the street lamp body 10 and the elastic reflector 6 tilt accordingly, and under the reflection of the elastic reflector 6, the light generated by the street lamp body 10 is simultaneously tilted and illuminates the road surface, which not only reduces the brightness of the road surface, but also causes the tilted light to directly shine on pedestrians or vehicles, thus causing unnecessary safety accidents; and when When severe natural environments such as strong winds or earthquakes occur, the aforementioned device lacks a shock-absorbing and buffering structure for the elastic reflector 6. This not only causes the reflected light from the elastic reflector 6 to sway, reducing the illumination quality of the road surface, but also easily causes the street lamp body 10 to tip over and be damaged, potentially injuring pedestrians or vehicles in the vicinity. To solve the above problems, this multifunctional adjustable smart street lamp for urban roads also includes: a brightness sensor is provided on one side of the top of the base 1. The brightness sensor is used to detect the brightness value of the street lamp body 10 reaching the end of the base 1 after being reflected by the elastic reflector 6. When the brightness sensor detects that the brightness of the base 1 is the preset brightness value, it indicates that the street lamp body 10 is in normal working condition and meets the required light intensity for the surrounding environment.

[0051] The elastic reflector 6 has an arc-shaped structure. The bottom of the elastic reflector 6 is coated with a reflective layer. The bottom area of ​​the elastic reflector 6 is larger than the top area of ​​the mounting base 501. Therefore, the light generated when the street lamp body 10 is turned on will be reflected to the area around the base 1 under the reflection of the reflective layer at the bottom of the elastic reflector 6, thereby illuminating the ground.

[0052] A magnetic ring 502 is provided on one inner wall of the slide 510. The magnetic ring 502 and the electromagnetic slide plate 505 have the same magnetism on their opposite ends. Therefore, when the controller controls the electromagnetic slide plate 505 to be energized, the electromagnetic slide plate 505 becomes magnetic. With the help of the magnetic repulsion between the electromagnetic slide plate 505 and the magnetic ring 502, the electromagnetic slide plate 505 is pulled to move the connecting spring 506 away from the magnetic ring 502. When the electromagnetic slide plate 505 moves, it simultaneously drives the pull rod 507 to move. Then, the pull rod 507 drives the locking block 503 to move laterally inside the slot 511 through the insertion and cooperation with the slot 504. When the slot 504 moves, it causes the elastic reflector 6 at the top to undergo elastic compression deformation. The two sides of the elastic reflector 6 move closer to the middle, so the opening angle of the two sides of the elastic reflector 6 decreases. The area of ​​the street lamp body 10 illuminated on the road surface after being reflected by the elastic reflector 6 is reduced.

[0053] In particular, since the top of the locking block 503 is hinged to the bottom of the elastic reflector 6, when the locking block 503 moves laterally within the slot 511, the hinged connection may prevent the two sides of the elastic reflector 6 from moving towards the center. To solve this problem, a stop block 513 is provided at the top of the slot 504 near the pull rod 507, and a groove 514 is provided at the top of the pull rod 507 near the locking block 503. A pneumatic push rod 515 is provided at the bottom of the groove 514. When the pull rod 507 is inserted into the slot 504, the controller activates the pneumatic push rod 515 inside the groove 514. The top of the push rod 515 moves upward and engages with one side of the stop block 513. At the same time, the end of the pull rod 507 presses against the inner wall of the slot 504. When the pull rod 507 drives the locking block 503 to move laterally inside the slot 511, the locking and limiting action of the stop block 513 and the pneumatic push rod 515 drives the locking block 503 to move laterally in a vertical state. The peripheral side of the locking block 503 is always parallel to the side wall of the slot 511. The locking block 503 will not tilt inside the slot 511, thereby realizing the adjustment of the opening angle of the elastic reflector 6 on both sides driven by the locking block 503.

[0054] Multiple sets of return springs 512 are evenly arranged on the side of the locking block 503 away from the pull rod 507. The other side of the return spring 512 is in sliding elastic contact with the inner wall of the slot 511. The return springs 512 improve the returnability and stability of the locking block 503 in the slot 511. The multiple sets of return springs 512 work together to improve the horizontality of the locking block 503 in the slot 511. They also help the stop block 513 and the pneumatic push rod 515 to ensure that the peripheral side of the locking block 503 is always parallel to the inner wall of the slot 511. At the same time, the return springs 512 can also absorb the kinetic energy of the locking block 503 in the lateral direction, thereby effectively improving the shock absorption and buffering effect of the locking block 503 in the lateral direction.

[0055] A bottom spring 516 is provided on the bottom side of the pull rod 507 near the locking block 503. The bottom spring 516 is in elastic contact with the inner bottom of the slot 504. When the pneumatic push rod 515 is pneumatically activated and moves upward, the top output end of the pneumatic push rod 515 will synchronously drive the locking block 503 to squeeze the bottom spring 516 and move upward. When the top output end of the pneumatic push rod 515 is activated in the opposite direction and moves downward, the locking block 503 will be driven downward under the elastic force of the bottom spring 516. At the same time, the bottom spring 516 can also absorb the kinetic energy of the vertical vibration of the locking block 503, effectively improving the shock absorption and buffering effect of the locking block 503 in the vertical direction.

[0056] A distance sensor is provided at the bottom of the connecting plate 2. The distance sensor is used to detect the distance between the connecting plate 2 and the ground, thereby indirectly obtaining the height change value of the street lamp body 10. An angle sensor is provided at the end of the connecting rod 308. The angle sensor is used to detect the rotation angle value of the connecting rod 308, thereby indirectly obtaining the rotation angle value of the street lamp body 10.

[0057] The width of the pneumatic push rod 515 matches the distance between the stop block 513 and the inner wall of the slot 504. Therefore, when the pneumatic push rod 515 is activated, it is locked in place with the stop block 513. The height of the slot 504 is greater than the height of the pull rod 507. When the pneumatic push rod 515 is activated, it drives the locking block 503 to move up and down by pressing against the top of the slot 504. The width of the slot 511 is greater than the width of the locking block 503. Therefore, the pull rod 507 is activated and drives the locking block 503 to move laterally inside the slot 511.

[0058] In use, the base 1 is fixed to the ground, and the outer end of the pull rod 507 is pulled to both sides. The pull rod 507 squeezes the connecting spring 506 and moves to both sides. At the same time, the locking block 503 is inserted into the slot 511. Under the elastic force of the return spring 512, the locking block 503 moves closer to the end of the pull rod 507 and contacts the inner wall of the slot 511. At this time, the distance between the two locking blocks 503 facing each other is the largest, and the opening angle of the elastic reflector 6 is the largest. Then, the pull rod 507 is released. Under the elastic force of the connecting spring 506, the pull rod 507 moves closer to the end of the locking block 503. At the same time, since the controller controls the pneumatic push rod 515 not to start at this time, the pneumatic push rod 515 is located inside the groove 514. The end of the pull rod 507 is inserted into the slot 504 to limit the position of the locking block 503, and the stop block 513 does not obstruct the insertion of the pull rod 507 into the slot 504.

[0059] The controller starts the street lamp body 10. The light generated by the street lamp body 10 shines upward into the elastic reflector 6 and is reflected onto the road surface by the reflective layer at the bottom of the elastic reflector 6. The brightness sensor at the top of the base 1 detects that the brightness value has reached the preset brightness value. If the brightness value detected by the brightness sensor is less than the preset brightness value, it means that the street lamp body 10 has been damaged. In this case, simply reverse the above process to disengage the card block 503 from the card slot 511 and replace the street lamp body 10.

[0060] After the installation and fixing of the elastic reflector 6 is completed, the controller controls the pneumatic push rod 515 to start extending and lock into the stop block 513. At the same time, the pneumatic push rod 515 presses against the inner top of the slot 504 and drives the locking block 503 to press the bottom spring 516 upward a certain distance, and the bottom of the locking block 503 disengages from the inner bottom of the slot 511.

[0061] When the controller activates the height adjustment mechanism 9 and moves the top connecting plate 2 upward, the distance value detected by the distance sensor increases. The connecting plate 2, through the angle adjustment mechanism 3 and the installation mechanism 5, simultaneously moves the top streetlight body 10 and the elastic reflector 6 upward. The area of ​​light from the streetlight body 10 reaching the ground after reflection by the elastic reflector 6 increases. Since the light intensity from the streetlight body 10 is constant, increasing the illuminated area reduces the ground brightness, decreasing the brightness value detected by the brightness sensor. This obstructs the normal movement of pedestrians or vehicles. Therefore, the controller activates the electromagnetic sliding plate 505, applies current, and generates magnetism. The electromagnetic sliding plate 505, through magnetic repulsion with the magnetic ring 502, moves the connecting spring 506 away from the magnetic ring 502. Simultaneously, the electromagnetic sliding plate 505 moves the pull rod 507 away from the magnetic ring 502. As the two ends move, the depth of the pull rod 507 inserted into the slot 504 increases. Under the limiting and locking action of the pneumatic push rod 515 and the stop block 513, the pull rod 507 drives the card block 503 to squeeze the reset spring 512 and move synchronously away from the magnetic ring 502. The distance between the facing end faces of the two sets of card blocks 503 decreases. Since the peripheral side of the card block 503 and the side wall of the slot 511 are always parallel to each other, the card block 503 drives the two sides of the top elastic reflector 6 to move inward. The opening angle of the two sides of the elastic reflector 6 decreases. With the light-gathering effect of the elastic reflector 6, the area of ​​the light generated by the street lamp body 10 illuminated on the base 1 by the reflection of the elastic reflector 6 decreases, and the corresponding light intensity increases. The brightness value detected by the brightness sensor increases again to the preset brightness value, thereby satisfying the illumination degree of the street lamp body 10 on the ground at different heights. The adjustability is stronger and the adaptability is better.

[0062] When the angle adjustment mechanism 3 is activated and causes the angle of the top mounting mechanism 5 to change, the angle sensor detects a deflection to one side and an increase in the angle value. Simultaneously, the mounting mechanism 5 increases the tilt angle of the top street lamp body 10 and the elastic reflector 6. Since the settings of each component of the angle adjustment mechanism 3 are constant, when the angle sensor detects that the connecting rod 308 has rotated a certain angle, the mounting mechanism 5 causes the top street lamp body 10 and the elastic reflector 6 to tilt to one side by a certain angle. Under the arc-shaped structure, the height of the street lamp body 10 and the elastic reflector 6 decreases synchronously. As can be seen from the above, in order to increase the reflection intensity of light from the elastic reflector 6 onto the street lamp body 10, the controller... The reduced current of the electromagnetic sliding plate 505 decreases the magnetic repulsion force between the electromagnetic sliding plate 505 and the magnetic ring 502. Under the elastic force of the connecting spring 506, the electromagnetic sliding plate 505 moves synchronously with the pull rod 507 closer to the magnetic ring 502. The pressure of the pull rod 507 on the inner wall of the slot 504 decreases. Under the elastic force of the return spring 512, the locking block 503 moves closer to the magnetic ring 502. The gap between the two sets of locking blocks 503 increases, and the locking blocks 503 move the two sides of the top elastic reflector 6 away from each other. The opening angle of the elastic reflector 6 increases, thus increasing the illumination range of the street light body 10 reflected onto the road surface, thereby ensuring that the illumination intensity still meets the requirements.

[0063] Meanwhile, since the elastic reflector 6 tilts as the installation mechanism 5 rotates, the light intensity generated by the elastic reflector 6 is tilted, which will not only affect pedestrians and vehicles passing by, but also has poor wind resistance and is easily overturned by the wind.

[0064] At this time, the controller controls the lower pneumatic push rod 515 to extend. The top output end of the pneumatic push rod 515, through pressing contact with the inner top of the slot 511, drives the locking block 503 to press the bottom spring 516 upward, while the upper pneumatic push rod 515 shortens. The pressing force of the top output end of the pneumatic push rod 515 on the inner top of the slot 511 decreases. Under the elastic force of the bottom spring 516, the locking block 503 moves downward. With the movement of the two sets of locking blocks 503 inside the slot 511, and through the hinge action with the bottom of the elastic reflector 6, the elastic reflector 6 is driven to rotate in the opposite direction, thereby making the elastic reflector 6 return to a horizontal state. The elastic reflector 6 can still wrap and reflect the top of the mounting base 501 in all directions. The light generated by the street lamp body 10 reaches the ground again to illuminate it under the reflection of the elastic reflector 6. With the help of the angle adjustment mechanism 3, the illumination position of the street lamp body 10 on the ground changes, thereby effectively improving the illumination range and meeting the usage needs under different conditions.

[0065] In particular, after the elastic reflector 6 changes from an inclined state to a horizontal state under the action of the two sets of locking blocks 503 at the bottom, the elastic reflector 6 will undergo elastic deformation under the hinge action. In particular, the opening angle of the two sides of the elastic reflector 6 will change. As a result, the brightness of the light reflected by the elastic reflector 6 after illuminating the ground after reflecting the light generated by the street lamp body 10 changes, and the brightness value detected by the brightness sensor changes. When the brightness value detected by the brightness sensor decreases, the controller controls the current of the electromagnetic sliding plate 505 to continue to increase. According to the above process, the opening angle of the elastic reflector 6 decreases, thereby increasing the brightness of the light reflected by the elastic reflector 6 after illuminating the ground after reflecting the light generated by the street lamp body 10, so as to meet the actual lighting needs.

[0066] In particular, during actual use, because the elastic reflector 6 is always in a horizontal state, and due to its own arc-shaped design, the elastic reflector 6 can buffer external wind forces, preventing the wind from overturning it. When ground vibrations occur or the wind is too strong, the angle adjustment mechanism 3, height adjustment mechanism 9, and mounting mechanism 5 may shake. When the mounting base 501 shakes laterally, multiple sets of return springs 512 absorb the kinetic energy of the vibration, thus preventing the lateral vibration from being absorbed. The force cannot be transmitted to the locking block 503. When the mounting base 501 vibrates vertically, the mounting base 501 transmits the vibration to the locking block 503 through the pull rod 507. However, the bottom spring 516 at the bottom of the locking block 503 absorbs the kinetic energy of the vibration, so that the vertical vibration force cannot be transmitted to the elastic reflector 6. This ensures the stability of the elastic reflector 6 at the top of the locking block 503, prevents the elastic reflector 6 from shaking and causing the reflected light on the ground to shake, thereby reducing the lighting comfort for pedestrians or vehicles.

[0067] When the ground shakes excessively, the distance and angle values ​​detected by the distance and angle sensors continuously change and exceed the preset values, indicating that the smart street light is at risk of tipping over. The controller then activates the height adjustment mechanism 9 in reverse, causing the top connecting plate 2 to descend to its lowest value. The angle adjustment mechanism 3 also activates in reverse, causing the installation mechanism 5 to remain vertical, thus minimizing damage to the street light body 10 should the device tip over. Simultaneously, the controller maximizes the current supplied to the electromagnetic sliding plate 505. The electromagnetic sliding plate 505, through the magnetic repulsion with the magnetic ring 502, stretches the connecting spring 506 and moves it away from the magnetic ring 502 to its maximum value. Simultaneously, the electromagnetic sliding plate 505 moves the pull rod 507 away from the magnetic ring 502 to its maximum value, maximizing the pressure between the end of the pull rod 507 and the slot 504. The pull rod 507 then causes the locking block 503 to compress the reset spring 512, moving it away from the magnetic ring 502 to its maximum value. At its maximum value, the distance between the two sets of locking blocks 503 facing each other is the smallest, the distance between the two sides of the top elastic reflector 6 moving towards the center is the largest, and the opening angle of the two sides of the elastic reflector 6 is the smallest. At the same time, the controller controls the pneumatic push rod 515 to start in the reverse direction and reach the initial height. The top output end of the pneumatic push rod 515 is engaged with the stop block 513. At the same time, under the elastic force of the bottom spring 516, the locking block 503 is moved downward to the maximum value and contacts the inner bottom of the slot 511. The locking block 503 simultaneously moves the elastic reflector 6 downward. Then, the two sides of the inner bottom of the elastic reflector 6 are pressed against the two top sides of the mounting base 501, which improves the protective performance of the elastic reflector 6 for the internal street lamp body 10. Even if the device tilts, the elastic structure of the elastic reflector 6 can provide elastic buffering and shock absorption for the internal mounting base 501 and street lamp body 10, avoiding damage to the internal street lamp body 10 and other structures after the device tilts.

[0068] After the shaking of the device is stopped, the height and tilt angle of the street lamp body 10 are adjusted again according to the above process, and the opening angle and level of the elastic reflector 6 are adjusted accordingly to achieve the best reflection effect of the elastic reflector 6 on the street lamp body 10.

[0069] This device boasts high detection accuracy and strong adjustability. It adaptively adjusts the opening angle and levelness of the elastic reflector 6 based on the height and tilt angle of the street lamp body 10. It is simple to operate, highly adaptable, and has superior functionality. The structures work together seamlessly, making it versatile. Furthermore, it can dampen and buffer external vibrations, ensuring strong stability. In extreme cases, it can also wrap and protect the street lamp body 10, reducing economic losses and meeting the actual lighting needs of pedestrians and vehicles.
