Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, specifically to a pole-mounted street light with efficient heat dissipation through airflow. Background Technology

[0002] For example, a high-efficiency heat dissipation street light, as disclosed in patent publication number CN103162202A, includes a light pole, a heat dissipation device directly or indirectly fixed to the light pole, and several LED light sources fixed to the heat dissipation device. The heat dissipation device includes a metal ventilation pipe, with an LED light source mounting area and a heat sink mounting area on the outer periphery of the ventilation pipe. Several heat sinks are fixed in the heat sink mounting area, and the ventilation pipe has several through holes penetrating its wall. An air intake channel is provided inside the light pole, with one end of the air intake channel connected to one end of the ventilation pipe. The air intake channel has several vent holes penetrating the light pole, located below the heat dissipation device. A fan is provided inside the air intake channel, and a temperature control switch for controlling the fan is provided inside the heat dissipation device. This design increases the number of LED light sources installed per unit area on the heat dissipation device without increasing its size, and the cooling effect increases with the increase of heat generated by the LED light sources. It is a reasonable design with low cost, making it an excellent choice for energy-saving retrofitting of road lighting.

[0003] However, during the use of the above-mentioned equipment, due to the design of its internal heat dissipation device, the requirements for heat dissipation and protection of the street light vary significantly depending on the climate characteristics of different seasons. When it is necessary to adjust the wind speed according to the ambient temperature, it is inconvenient to adjust it quickly, which reduces work efficiency. Therefore, in order to address this situation, we propose a more convenient and practical heat dissipation street light to meet the usage requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency heat dissipation street light with through-flow on the pole, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pole-mounted street light with efficient heat dissipation through airflow, comprising a foundation, a heat dissipation mechanism on the top of the foundation, an opening and closing mechanism on the top of the heat dissipation mechanism for adjusting wind speed, the opening and closing mechanism comprising a connecting ring, a rotating ring rotatably connected to the top of the connecting ring, at least four rotating grooves on the top of the rotating ring, rotating columns rotatably connected to the inner walls of the rotating grooves, one end of the rotating column rotatably connected to the connecting ring, a fixed column fixedly connected to one side of the top of the rotating ring, a rotating rod rotatably connected to one end of the fixed column, a connecting column rotatably connected to one end of the rotating rod, an opening and closing assembly on one side of the connecting column, a connecting mechanism on the top of the opening and closing mechanism, and a lighting mechanism on the top of the connecting mechanism.

[0006] Furthermore, the heat dissipation mechanism includes a fixing plate with multiple equidistant mounting holes through the top of the fixing plate. A first support tube is fixedly connected to the center of the top of the fixing plate. The first support tube is connected to a connecting ring. A slot is opened on one side of the first support tube, and a fixing frame is fixedly connected inside the slot. A temperature sensor is installed on one side of the fixing frame.

[0007] Furthermore, fixing blocks are fixedly connected to both sides of the fixing frame, a limit hole is opened through one side of the fixing block, an installation frame is fixedly connected to the inner wall of one side of the fixing frame, and a fan is installed on one side of the installation frame.

[0008] Furthermore, a partition is provided on one side of the fixed frame, and multiple equidistant heat dissipation holes are opened through one side of the partition. Connecting blocks are fixedly connected to both sides of the partition, and a limiting plunger is fixedly connected to one side of the connecting block. The limiting plunger and the limiting hole are compatible with each other.

[0009] Furthermore, the opening and closing assembly includes a fixing ring with a through hole on one side, which is rotatably connected to a connecting post. Multiple equidistant opening and closing plates are rotatably connected to the bottom side of the fixing ring, and the opening and closing plates are connected to the connecting post.

[0010] Furthermore, a plurality of equidistant toothed blocks are fixedly connected to one side of the rotating ring, and a through hole is opened on one side of the top of the connecting ring. A rotating shaft is rotatably connected inside the through hole, and a gear is fixedly connected to one end of the rotating shaft. The teeth of the gear and the toothed blocks mesh with each other. A servo motor is installed at the bottom of the connecting ring, and the output end of the servo motor is connected to the rotating shaft.

[0011] Furthermore, the connecting mechanism includes a sealing cap, which is connected to a connecting ring. A lower connecting pipe is fixedly connected to the top center of the sealing cap. A first threaded groove is opened on the outer wall of the lower connecting pipe, and a second support pipe is threaded to one end of the lower connecting pipe.

[0012] Furthermore, a guide spiral plate is fixedly connected to the inner wall of the second support tube, an upper connecting tube is fixedly connected to one end of the second support tube, a second threaded groove is opened on the outer wall of the upper connecting tube, and a fixed tube is threadedly connected to one end of the upper connecting tube.

[0013] Furthermore, the lighting mechanism includes a street lamp body, a through hole on one side of the street lamp body, a ventilation pipe fixedly connected in the through hole, one end of the ventilation pipe and the fixed pipe being threadedly connected, a mounting plate fixedly connected to one side of the street lamp body, a plurality of equidistant reflectors fixedly connected to one side of the mounting plate, an LED light installed on one side of the mounting plate between the reflectors, and a protective light-transmitting cover fixedly connected to one side of the street lamp body.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This pole light features a through-flow, high-efficiency heat dissipation system. Through its heat dissipation and opening / closing mechanisms, when wind speed needs adjustment, a servo motor drives a rotating shaft and gears to rotate. This, in turn, causes a gear block and a rotating ring to rotate on a connecting ring. The rotating ring's rotation is achieved through a rotating groove and a rotating column, which, in turn, coordinates with the fixed column, rotating rod, and connecting column to synchronously open or close the opening / closing plate, thus adjusting the wind speed. This device can precisely control the opening and closing degree of the top ventilation opening, thereby adjusting the amount of airflow for optimal heat dissipation. It is highly practical and suitable for widespread adoption.

[0016] Meanwhile, the heat dissipation mechanism can monitor the internal temperature of the light pole in real time and automatically control the start and stop of the fan accordingly, realizing intelligent management, which not only ensures the heat dissipation effect but also avoids energy waste.

[0023] 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.

[0024] In the use of lighting equipment, heat-dissipating streetlights are required. Before installation, the heat-dissipating streetlights provided by this invention require ensuring the foundation 1 is solid and meets design requirements. Regular cleaning is necessary, especially of the heat dissipation holes 211 of the heat dissipation mechanism 2, the fan 209, and the lampshade of the lighting mechanism 6. Dust and dirt accumulate in these areas, affecting heat dissipation and lighting brightness. Appropriate cleaning tools and methods should be used to avoid scratching the lamp surface. When installing streetlights in windy areas, wind resistance must be considered. The connection between the foundation 1 and the streetlight can be appropriately reinforced to ensure the streetlight is not damaged in strong winds. Simultaneously, the opening and closing mechanism 3 should be adjusted according to wind conditions to prevent strong winds from impacting the interior of the streetlight.

[0025] like Figures 1-5 As shown, the present invention provides a technical solution: a pole-mounted street light with efficient heat dissipation through airflow, comprising a foundation 1, a heat dissipation mechanism 2 on the top of the foundation 1, and an opening and closing mechanism 3 on the top of the heat dissipation mechanism 2 for adjusting wind speed. The opening and closing mechanism 3 includes a connecting ring 301, a rotating ring 302 rotatably connected to the top of the connecting ring 301, at least four rotating grooves 303 on the top of the rotating ring 302, a rotating column 304 rotatably connected to the inner wall of the rotating groove 303, one end of the rotating column 304 rotatably connected to the connecting ring 301, a fixed column 305 fixedly connected to one side of the top of the rotating ring 302, a rotating rod 306 rotatably connected to one end of the fixed column 305, a connecting column 307 rotatably connected to one end of the rotating rod 306, an opening and closing assembly on one side of the connecting column 307, a connecting mechanism 4 on the top of the opening and closing mechanism 3, and a lighting mechanism 6 on the top of the connecting mechanism 4.

[0026] like Figure 2As shown, the heat dissipation mechanism 2 includes a fixing plate 201. Multiple equidistant mounting holes 202 are provided through the top of the fixing plate 201. A first support tube 203 is fixedly connected to the center of the top of the fixing plate 201. The first support tube 203 is connected to a connecting ring 301. A slot is provided on one side of the first support tube 203, and a fixing frame 204 is fixedly connected inside the slot. A temperature sensor 205 is installed on one side of the fixing frame 204. Fixing blocks 206 are fixedly connected to both sides of the fixing frame 204. A limiting hole 207 is provided through one side of the fixing block 206. A mounting frame 208 is fixedly connected to the inner wall of one side of the fixing frame 204. A fan 209 is installed on one side of the mounting frame 208. A partition plate 210 is provided on one side of the fixing frame 204. Multiple equidistant heat dissipation holes 211 are provided through one side of the partition plate 210. Connecting blocks 212 are fixedly connected to both sides of the partition plate 210. A limiting plunger 213 is fixedly connected to one side of the connecting block 212. The limiting plunger 213 and the limiting hole 207 are compatible.

[0027] It should be noted that the limiting plunger 213 is made of rubber. During use, the first support tube 203 is first fixed to the foundation 1 through the fixing plate 201 and the mounting hole 202. Then, the limiting plunger 213 is inserted into the limiting hole 207, thereby inserting the connecting block 212 and the partition 210 into the fixing frame 204. The temperature sensor 205 on one side of the fixing frame 204 monitors the ambient temperature. When a high temperature signal is detected, the fan 209 on the mounting frame 208 starts, generating a strong suction. External cold air is drawn in from the heat dissipation hole 211 on the partition 210 and filtered, then gathers into the pipe of the first support tube 203 and begins to flow upward. The heat dissipation mechanism 2 can monitor the internal temperature of the lamp post in real time and automatically control the start and stop of the fan 209 accordingly, realizing intelligent management, which not only ensures the heat dissipation effect but also avoids energy waste.

[0028] like Figure 3 As shown, the opening and closing assembly includes a fixed ring 308, with a through hole on one side of the fixed ring 308, which is rotatably connected to a connecting post 307. Multiple equidistant opening and closing plates 309 are rotatably connected to the bottom side of the fixed ring 308, and the opening and closing plates 309 are connected to the connecting post 307. Multiple equidistant toothed blocks 310 are fixedly connected to one side of the rotating ring 302. A through hole is opened on the top side of the connecting ring 301, and a rotating shaft 311 is rotatably connected inside the through hole. A gear 312 is fixedly connected to one end of the rotating shaft 311, and the gear 312 meshes with the teeth of the toothed blocks 310. A servo motor 313 is installed at the bottom of the connecting ring 301, and the output end of the servo motor 313 is connected to the rotating shaft 311.

[0029] It should be noted that during use, when the wind speed needs to be adjusted, the servo motor 313 drives the rotating shaft 311 and gear 312 to rotate, thereby driving the toothed block 310 and the rotating ring 302 to rotate on the connecting ring 301. In this process, the rotation of the rotating ring 302 is achieved through the cooperation of the rotating groove 303 and the rotating column 304, thereby enabling the synchronous opening or closing movement of the opening and closing plate 309 through the cooperation of the fixed column 305, the rotating rod 306 and the connecting column 307, thus adjusting the wind speed. The opening and closing mechanism 3 can effectively prevent moisture, dust and other pollutants from entering the lamp post and protect the internal electronic components.

[0030] like Figure 4 As shown, the connecting mechanism 4 includes a sealing cover 401, which is connected to a connecting ring 301. A lower connecting pipe 402 is fixedly connected to the top center of the sealing cover 401. A first threaded groove 403 is provided on the outer wall of the lower connecting pipe 402. A second support pipe 404 is threadedly connected to one end of the lower connecting pipe 402. A guide spiral plate 405 is fixedly connected to the inner wall of the second support pipe 404. An upper connecting pipe 406 is fixedly connected to one end of the second support pipe 404. A second threaded groove 407 is provided on the outer wall of the upper connecting pipe 406. A fixed pipe 5 is threadedly connected to one end of the upper connecting pipe 406.

[0031] It should be noted that during use, the second support pipe 404 and the sealing cover 401 are first connected through the lower connecting pipe 402 and the first threaded groove 403. Then, the second support pipe 404 and the fixed pipe 5 are connected through the upper connecting pipe 406 and the second threaded groove 407. Finally, the air flow rate is accelerated under the action of the guide spiral plate 405. The connecting mechanism 4 makes the installation and disassembly of each component very convenient, which facilitates the assembly, maintenance and replacement of parts of the street light.

[0032] like Figure 5 As shown, the lighting mechanism 6 includes a street lamp body 601. A through hole is opened on one side of the street lamp body 601, and a ventilation pipe 602 is fixedly connected in the through hole. One end of the ventilation pipe 602 is threadedly connected to the fixed pipe 5. A mounting plate 603 is fixedly connected to one side of the street lamp body 601. Multiple equidistant reflectors 604 are fixedly connected to one side of the mounting plate 603. LED lights 605 are installed on one side of the mounting plate 603 between the reflectors 604. A protective light-transmitting cover 606 is fixedly connected to one side of the street lamp body 601.

[0033] It is important to note that during use, firstly, the ventilation pipe 602 on one side of the street light body 601 is connected to the fixing pipe 5 to introduce cool air from inside the light pole into the LED light 605 for cooling and heat dissipation. The reflector 604 reflects and focuses the light from the LED light 605, enhancing the lighting effect and making the light more uniform and bright. Finally, the protective light-transmitting cover 606 protects the LED light 605 and the reflector 604. The heat generated by the street light body 601 can also be discharged to the outside of the light pole through the ventilation pipe 602, forming a good heat dissipation cycle, ensuring that the LED light 605 works in a suitable temperature environment and extending the service life of the LED light 605.

[0034] During use, the temperature sensor 205 first monitors the internal ambient temperature of the lamp post in real time. When the temperature exceeds the preset threshold, the temperature sensor 205 sends a signal, the servo motor 313 starts, drives the gear 312 to rotate, and drives the rotating ring 302 and its opening and closing components to move, opening the opening and closing plate 309 to form a top ventilation opening. At the same time, the fan 209 starts, forcibly sucking in the cool air at the bottom of the lamp post. Driven by the fan 209, the airflow flows upward through the through pipe formed by the second support pipe 404. The guide spiral plate 405 in the pipe makes the air rotate and rise, enhancing the heat exchange efficiency with the inner wall of the lamp post. Finally, this cooling airflow reaches the top and takes away a large amount of heat generated by the LED lamp 605, and is discharged through the opened top ventilation opening. This device can precisely control the opening and closing degree of the top ventilation opening, thereby adjusting the amount of heat dissipation airflow and optimizing the heat dissipation efficiency.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
