Description

Technical Field

[0001] This utility model relates to the field of street light technology, specifically an environmentally friendly street light for urban roads. Background Technology

[0002] With the continuous acceleration of urbanization and the ongoing expansion of urban road construction, streetlights, as a crucial infrastructure for ensuring nighttime traffic safety and enhancing urban nighttime functionality, are seeing increasing application scope and demand. Currently, most urban streetlights on the market adopt traditional structural designs, typically consisting of a single pole, fixed lighting components, and an external power supply system. Some environmentally friendly streetlights integrate solar panels or small wind power generation devices to achieve energy self-sufficiency, thus meeting the demand for green and environmentally friendly use to a certain extent and providing a basic guarantee for urban road nighttime lighting.

[0003] However, in practical applications, existing urban streetlights still suffer from significant deficiencies in maintenance convenience. Because streetlights need to meet the lighting requirements of a large area of ​​the road, the overall height of the poles is usually quite high. Lighting components, power generation components, and related electrical components are all installed at the top of the pole. When these components malfunction and require repair or regular maintenance, workers must use aerial work platforms (such as aerial work vehicles) to reach the work location. This not only increases equipment rental costs and maintenance time but also poses safety risks associated with working at height. Furthermore, while some streetlights have attempted to optimize the maintenance process by disassembling the pole structure, the lack of stable auxiliary support mechanisms after disassembly makes the process of lowering and resetting the lamp body cumbersome, further reducing maintenance efficiency and failing to meet the actual needs of rapid maintenance and ensuring continuous road lighting in urban streetlights. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an environmentally friendly street light for urban roads. This technical solution solves the significant maintenance inconvenience defects of existing urban road street lights mentioned in the background. Because street lights need to meet the lighting needs of a large area of ​​the road, the overall height of the light pole is usually quite high. The lighting components, power generation components, and related electrical components are all installed at the top of the light pole. When these components malfunction and require repair or regular maintenance, workers need to use aerial work platforms (such as aerial work vehicles) to reach the work location, which not only increases equipment rental costs and maintenance time costs but also poses safety risks associated with working at height. Furthermore, although some street lights attempt to optimize the maintenance process by disassembling the light pole structure, the lack of stable auxiliary support mechanisms after disassembly makes the process of lowering and resetting the light body cumbersome, further reducing maintenance efficiency and failing to meet the actual needs of rapid maintenance and ensuring continuous road lighting in urban roads.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Example 1 Please refer to Figures 1 to 6As shown, an environmentally friendly street light for urban roads includes a first light pole 1, a second light pole 2 at the top of the first light pole 1, a lighting lamp 3 and a power storage mechanism 4 fixedly connected to the front and rear sides of the top end of the second light pole 2, a mounting plate 5 fixedly connected to the top of the second light pole 2, a solar panel 6 fixedly connected to the front top of the mounting plate 5, a small wind turbine 7 fixedly connected to the rear top of the mounting plate 5, a sound sensor 8 on the right side of the second light pole 2, and a light sensor 9 on the top of the lighting lamp 3. Both the sound sensor 8 and the light sensor 9 are electrically connected to the lighting lamp 3. 3. The solar panel 6 and the small wind turbine 7 are both electrically connected to the energy storage mechanism 4. The bottom of the second lamp post 2 is provided with a docking groove 10. The top of the first lamp post 1 is fixedly connected with a docking plate 11 that is compatible with the docking groove 10. The docking plate 11 is located in the docking groove 10, and the top of the docking plate 11 is hinged in the docking groove 10 near the top. A fixing component 12 is provided between the second lamp post 2 and the docking plate 11. A horizontally arranged hanging rod 13 is fixedly connected to the rear side of the bottom end of the second lamp post 2. A retractable traction and lowering mechanism 14 that cooperates with the hanging rod 13 is provided on the rear side of the first lamp post 1.

[0018] Those skilled in the art will understand that the device includes a first lamp post 1 and a second lamp post 2. The docking groove 10 at the bottom of the second lamp post 2 is hinged to the docking plate 11 at the top of the first lamp post 1, and the two are fixed by a fixing component 12. The solar panel 6 and the small wind turbine 7 on the mounting plate 5 at the top of the second lamp post 2 convert light energy and wind energy into electrical energy and store it in the energy storage mechanism 4 to power the lighting lamp 3. The photosensitive sensor 9 senses the light intensity and the sound sensor 8 senses the ambient sound. The two together control the opening and closing of the lighting lamp 3. When maintenance is required, the fixing component 12 is released, and the second lamp post 2 is smoothly lowered by the cooperation of the retractable traction and lowering mechanism 14 on the rear side of the first lamp post 1 and the hanging rod 13 at the bottom of the second lamp post 2.

[0019] The device employs a hinged double-lamp pole structure and a retractable traction and lowering mechanism 14, which allows for the maintenance of components such as the top lighting lamp 3 and solar panel 6 without relying on high-altitude work equipment, reducing maintenance costs and the risks of high-altitude operations. The dual-energy power supply design enables energy self-sufficiency, meets environmental protection requirements, and the sensor automatically controls the lighting, improving energy utilization efficiency.

[0020] Example 2 Furthermore, a mounting base plate 15 is fixedly connected to the bottom of the first lamp post 1, and reinforcing ribs 16 are fixedly connected between the four sides of the first lamp post 1 and the mounting base plate 15. Mounting holes 17 are provided at the four corners of the mounting base plate 15.

[0021] Those skilled in the art will understand that the bottom of the first light pole 1 is fixedly connected to the mounting base plate 15, and the mounting holes 17 at the four corners of the mounting base plate 15 are used to fix the entire street light to the ground foundation with bolts; the reinforcing ribs 16 between the four sides of the first light pole 1 and the mounting base plate 15 enhance the connection strength between the first light pole 1 and the mounting base plate 15 through the triangular stabilizing structure, and disperse the pressure of the overall weight of the light pole on the mounting base plate 15.

[0022] The mounting base plate 15 and the mounting hole 17 work together to ensure that the street light is accurately positioned and firmly fixed, preventing the street light from tilting due to unstable installation; the reinforcing rib 16 effectively improves the load-bearing capacity and wind resistance of the bottom of the light pole, extends the overall service life of the street light, and adapts to the complex outdoor environment of urban roads.

[0023] Example 3 Furthermore, the bottom left and right sides of the second lamp post 2 are fixedly connected with auxiliary handles 18 to facilitate the operator's grip when laying down or maintaining the second lamp post 2. The top front side of the first lamp post 1 is provided with a limiting protrusion 19 that matches the bottom of the second lamp post 2. The second lamp post 2 is provided with a weight reduction groove 20.

[0024] Those skilled in the art will understand that the auxiliary grips 18 on the left and right sides of the bottom end of the second lamp post 2 are for the operator to hold when the second lamp post 2 is lowered or reset, so as to facilitate the application of force to control the posture of the lamp post; the limiting protrusion 19 on the front side of the top of the first lamp post 1 contacts the bottom end of the second lamp post 2 when the second lamp post 2 is reset to the vertical state, restricting the excessive rotation of the second lamp post 2 and ensuring its accurate reset; the weight reduction groove 20 on the second lamp post 2 reduces the weight of the second lamp post 2 itself without affecting the structural strength of the lamp post, thereby reducing the traction load of the retractable traction and lowering mechanism 14.

[0025] The auxiliary grip 18 improves the operator's control over the process of lowering and resetting the light pole, reducing the difficulty of operation; the limiting protrusion 19 ensures the resetting accuracy of the light pole and avoids the installation of the subsequent fixing components 12 due to resetting deviation; the weight reduction groove 20 reduces the weight of the light pole, which not only reduces the energy consumption of the traction mechanism, but also facilitates transportation and installation.

[0026] Example 4 Furthermore, a protective cover 21 is provided on the rear side of the first lamp post 1, covering the outside of the retractable traction and lowering mechanism 14. The open end of the protective cover 21 has an outer edge. A sealing gasket 22 made of nitrile rubber is fixedly connected to the side of the outer edge of the protective cover 21 near the first lamp post 1. The sealing gasket 22 achieves a sealed fit with the first lamp post 1 by compression. Screws 23 are threadedly connected to the four corners of the outer edge of the protective cover 21 and the first lamp post 1.

[0027] Those skilled in the art will understand that the protective cover 21 on the rear side of the first lamp post 1 completely covers the retractable traction and lowering mechanism 14, preventing rainwater, dust, debris, etc. from entering the interior of the mechanism; the nitrile rubber sealing gasket 22 on the outer edge of the open end of the protective cover 21 near the first lamp post 1 achieves a sealed fit between the protective cover 21 and the first lamp post 1 through the squeezing action when the screws 23 are fixed, further enhancing the protective effect; the screws 23 at the four corners of the outer edge of the protective cover 21 are used to detachably fix the protective cover 21 to the first lamp post 1, facilitating subsequent maintenance of the traction mechanism.

[0028] The cooperation between the protective cover 21 and the sealing gasket 22 effectively protects the retractable traction and lowering mechanism 14 from the corrosion of harsh outdoor environments, prevents the internal parts of the mechanism from rusting and jamming, and ensures the stability of the traction function; the detachable fixing design takes into account both protection and maintenance convenience, and the internal mechanism can be maintained without damaging the protective cover 21.

[0029] Example 5 Furthermore, the fixing component 12 includes two first through holes 1201 horizontally opened on the docking plate 11 and arranged vertically at intervals. The second lamp post 2 has two second through holes 1202 corresponding to the two first through holes 1201 respectively. A screw 1203 is passed through the second through hole 1202 and the corresponding first through hole 1201. One end of the two screws 1203 is fixedly connected to a connecting plate 1204. The other end of the two screws 1203 is threadedly connected to a slotted nut 1205. A round hole is also opened at the end of the screw 1203 connected to the slotted nut 1205. A cotter pin 1206 that cooperates with the slotted nut 1205 is provided in the round hole.

[0030] Those skilled in the art will understand that the two first through holes 1201 of the fixing component 12 are spaced apart vertically on the docking plate 11, and the two second through holes 1202 on the second lamp post 2 correspond one-to-one with the first through holes 1201; when the second lamp post 2 is reset, the screw 1203 is passed through the corresponding second through hole 1202 and the first through hole 1201, and the connecting plate 1204 ensures that the two screws 1203 are installed synchronously; the slotted nut 1205 is screwed on the other end of the screw 1203 to fix the docking plate 11 and the second lamp post 2, and finally the cotter pin 1206 is inserted into the round hole at the end of the screw 1203 to prevent the slotted nut 1205 from loosening.

[0031] The double fixing design of the upper and lower screws 1203 enhances the connection stability between the docking plate 11 and the second lamp post 2, preventing the lamp post from shaking during use; the slotted nut 1205 and the cotter pin 1206 work together to achieve anti-loosening locking, preventing the nut from loosening due to vibration, and ensuring the structural safety of the lamp post in the vertical state.

[0032] Example 6 Furthermore, the retractable traction and folding mechanism 14 includes two fixed plates 1401 fixedly connected to the rear side of the first lamp post 1 and spaced apart from each other. A guide pulley 1402 is rotatably connected between the two fixed plates 1401. At the same time, a retractable frame 1403 located directly below the guide pulley 1402 is also fixedly connected to the rear side of the first lamp post 1. A traction rope 1404 is wound on the retractable frame 1403. One end of the traction rope 1404 is fixedly connected to the retractable shaft of the retractable frame 1403, and the other end of the traction rope 1404 is fixedly connected to a locking hook 1405 that cooperates with the hanging rod 13. A drive unit 1406 located below the retractable frame 1403 is also provided on the rear side of the first lamp post 1. The drive unit 1406 is used to drive the retractable shaft of the retractable frame 1403 to rotate.

[0033] Those skilled in the art will understand that the two fixed plates 1401 of the retractable traction and lowering mechanism 14 are fixed to the rear side of the first lamp post 1, and the guide pulley 1402 between the two guides the traction rope 1404; the retractable frame 1403 is fixed directly below the guide pulley 1402, and one end of the traction rope 1404 wound on it is fixed to the retractable shaft of the retractable frame 1403, and the other end of the locking hook 1405 is connected to and locked to the hanging rod 13 of the second lamp post 2; the drive unit 1406 drives the retractable shaft of the retractable frame 1403 to rotate, thereby realizing the retracting and lowering of the traction rope 1404, and thus driving the second lamp post 2 to be lowered or reset around the hinge point.

[0034] The guide pulley 1402 ensures the stability of the force direction during the winding and unwinding of the traction rope 1404, preventing the traction rope 1404 from deviating or wearing out; the locking hook 1405 and the hanging rod 13 lock together to prevent the hook from falling off during the traction process, ensuring the safety of the light pole when it is lowered and reset; the winding and unwinding frame 1403 and the drive unit 1406 work together to realize the automated winding and unwinding of the traction rope 1404, reducing the labor intensity of the operators.

[0035] Example 7 Furthermore, the drive unit 1406 includes a first gear 14061 fixedly connected to one end of the take-up and put-down shaft of the take-up and put-down rack 1403. A fixed frame 14062 located below the take-up and put-down rack 1403 is fixedly connected to the rear side of the first lamp post 1. A horizontally arranged rotating shaft 14063 is rotatably connected to the fixed frame 14062. A second gear 14064 meshing with the first gear 14061 is fixedly connected to one end of the rotating shaft 14063. A worm gear 14065 is fixedly connected to the other end of the rotating shaft 14063. A drive motor 14066 is fixedly connected to the rear side of the first lamp post 1. The drive motor 14066 is electrically connected to the energy storage mechanism 4. A worm 14067 meshing with the worm gear 14065 is fixedly connected to the output end of the drive motor 14066. The worm gear 14067 and worm gear 14065 transmission mechanism has a self-locking function, which can prevent the take-up and put-down shaft of the take-up and put-down rack 1403 from reversing when there is no driving force.

[0036] As will be understood by those skilled in the art, the first gear 14061 of the drive unit 1406 is fixed to one end of the take-up and take-down shaft of the take-up and take-down rack 1403 and meshes with the second gear 14064 on the rotating shaft 14063; the rotating shaft 14063 is rotatably connected to the rear side of the first lamp post 1 through the fixing frame 14062, and the worm gear 14065 at its other end meshes with the worm 14067 at the output end of the drive motor 14066; the drive motor 14066 is powered by the energy storage mechanism 4, and after starting, it drives the worm gear 14065 to rotate through the worm 14067, and then drives the take-up and take-down shaft of the take-up and take-down rack 1403 to rotate through the transmission of the rotating shaft 14063, the second gear 14064, and the first gear 14061; the transmission mechanism of the worm 14067 and the worm gear 14065 has a self-locking function, which can prevent the take-up and take-down shaft from reversing when there is no driving force.

[0037] The multi-stage transmission design of gears and worm gears 14067 and worm wheel 14065 achieves speed reduction and torque increase, ensuring that the drive motor 14066 can stably drive the take-up and take-down frame 1403 to take up and take down the traction rope 1404, adapting to the weight requirements of the second light pole 2; the self-locking function of the worm gear 14067 and worm wheel 14065 transmission prevents the take-up and take-down shaft from reversing due to accidental power failure or motor failure during the light pole lowering process, avoiding the light pole from suddenly falling and improving operational safety.

[0038] In this embodiment, the energy storage mechanism 4, solar panel 6, small wind turbine 7, acoustic sensor 8, photosensitive sensor 9, and drive motor 14066 used in this application are all existing technologies, and the connections between the components are also existing technologies. Therefore, their connection relationships and principles will not be described in detail here.

[0039] The working principle and usage procedure of this device are as follows: During the installation phase, the entire street light is first fixed to the ground foundation using bolts through the mounting holes 17 at the four corners of the mounting base plate 15 at the bottom of the first light pole 1. The reinforcing ribs 16 between the first light pole 1 and the mounting base plate 15 enhance the bottom connection strength. After installation, the second light pole 2 is hinged to the docking plate 11 at the top of the first light pole 1 through the bottom docking groove 10. The two screws 1203 in the fixing assembly 12 are respectively passed through the second through hole 1202 of the second light pole 2 and the first through hole 1201 of the docking plate 11. One end of the screw 1203 is positioned by the connecting plate 1204, and the other end is screwed with a slotted nut 1205 and locked by inserting a cotter pin 1206, thus completing the second light pole installation. 2. Fixing; During daily use, the solar panel 6 on the top mounting plate 5 of the second lamp post 2 converts light energy into electrical energy, and the small wind turbine 7 converts wind energy into electrical energy, both stored in the energy storage mechanism 4. When the photosensitive sensor 9 detects insufficient ambient light and the sound-sensitive sensor 8 detects ambient sound, both together control the lighting lamp 3 to turn on, providing lighting for the road. When it is necessary to repair the lighting lamp 3, solar panel 6, small wind turbine 7, etc., first remove the screws 23 on the outer edge of the protective cover 21 on the rear side of the first lamp post 1, open the protective cover 21, and pull out the locking hook 1405 at one end of the traction rope 1404 on the retracting frame 1403 in the retractable traction and lowering mechanism 14, and pass it around the guide pulley 1402. Then connect and lock it to the hanging rod 13 on the rear side of the bottom end of the second lamp post 2; then remove the cotter pin 1206 at the end of the screw 1203 in the fixing assembly 12, unscrew the slotted nut 1205, and release the fixing between the second lamp post 2 and the docking plate 11; start the drive motor 14066 in the drive unit 1406. The drive motor 14066 is powered by the energy storage mechanism 4. The worm gear 14067 at its output end drives the worm wheel 14065 to rotate. The worm wheel 14065 drives the second gear 14064 to rotate through the rotating shaft 14063. The second gear 14064 meshes with the first gear 14061, thereby driving the take-up and release shaft of the take-up and release frame 1403 to rotate and release the traction rope 1404. The operator holds the second The auxiliary handles 18 on the left and right sides at the bottom of the lamp post 2, in conjunction with the release speed of the traction rope 1404, slowly lower the second lamp post 2 to a low position around the hinge point of the docking plate 11 and the docking groove 10. At this time, the self-locking function of the worm gear 14067 and the worm wheel 14065 prevents the take-up and release shaft from reversing, ensuring that the second lamp post 2 is stably stopped in the low position, and the operator can carry out maintenance work. After the maintenance is completed, the drive motor 14066 is started again to drive the take-up and release shaft of the take-up and release frame 1403 to reverse and retract the traction rope 1404, pulling the second lamp post 2 to reset around the hinge point. When the bottom of the second lamp post 2 contacts the limiting protrusion 19 on the front side of the top of the first lamp post 1, the lamp post is reset to the vertical position, and the drive motor 14066 is stopped.Then, the screw 1203 of the fixing component 12 is passed through the corresponding through hole again, the slotted nut 1205 is screwed on, and the cotter pin 1206 is inserted to lock it. The locking hook 1405 is then separated from the hanging rod 13, the traction rope 1404 is retrieved onto the retraction frame 1403, the protective cover 21 is covered, and it is secured with screws 23. The sealing gasket 22 inside the protective cover 21 provides a seal, completing the entire maintenance process, and the street light is back in normal use.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
