Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an urban environmental lighting device. Background Technology

[0002] With the acceleration of urbanization, urban environmental lighting devices, as an important part of urban infrastructure, are constantly being improved in design and function to meet diverse urban lighting needs. Among them, high mast lights, also known as road high mast lights or high mast road lights, are lighting facilities installed on both sides or in the center of roads at a relatively high height (usually more than 10 meters).

[0003] Traditional high-mast lights mostly use a motor to drive a rope to raise the light frame equipped with the lights to a suitable position. Usually, the rope tension is used to fix the light frame at a suitable height. Without effective and additional support, if the rope is damaged, the light frame is prone to slipping and causing safety accidents. In addition, the light frame is prone to swaying during the raising and lowering process, which affects the installation or maintenance of the light frame. Therefore, we propose an urban environmental lighting device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as traditional high-mast lights that usually use rope tension to fix the light frame at a suitable height, which lacks effective and additional support, and the light frame is prone to swaying during the lifting and lowering process, affecting the installation or maintenance of the light frame. Therefore, this utility model proposes an urban environmental lighting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An urban environmental lighting device includes a lamp post, which is hollow. A mounting base is fixedly installed at the bottom of the lamp post. An installation opening for easy installation is provided on the lamp post above the mounting base. A sealing door is hinged to the lamp post at the installation opening. A PLC control box is installed inside the sealing door. A lamp holder is slidably fitted on the outer wall of the lamp post. Multiple lighting lamps are fixedly installed on the lamp holder at equal intervals by mounting brackets. A mounting plate is provided at the top of the lamp post. An opening communicating with the interior of the lamp post is provided on the mounting plate. A protective cover for protection is fixedly installed on the top of the mounting plate.

[0007] Two limiting plates are symmetrically fixedly installed on the outer wall of the lamp post. Two grooves are symmetrically opened on both sides of the two limiting plates. Three multi-wheel guide groups are fixedly installed at equal intervals on the top of the mounting plate. Connecting ropes are laid on the three multi-wheel guide groups. A connecting plate is installed inside the lamp post. One end of each of the three connecting ropes is fixedly connected to the lamp holder. The other end of each of the three connecting ropes extends into the inside of the lamp post and is fixedly connected to the top of the connecting plate.

[0008] The multi-wheel guide assembly includes two support plates, which are fixedly mounted on the top of the mounting plate. Two guide wheels are rotatably connected between the two support plates, and the connecting rope is laid on the corresponding guide wheels.

[0009] The device also includes:

[0010] The lifting assembly is located inside the lamp post and is used to drive the connecting plate to rise and fall, thereby driving the lamp holder connected to the connecting plate to rise and fall.

[0011] Two sets of limiting components are set on corresponding limiting plates to limit the position of the lamp holder and prevent it from shaking.

[0012] Two sets of support components are symmetrically arranged on the outer wall of the lamp post to support the lamp holder when it is raised to the required height and to further fix the lamp holder.

[0013] In one possible design, the lifting assembly includes a mounting box fixedly disposed at the mounting opening inside the lamp post. A rope storage wheel is rotatably connected inside the mounting box via a rotating shaft. A lifting rope is wound around the rope storage wheel, one end of which is fixedly connected to the bottom of a connecting disc. A first driven gear is fixedly sleeved on the outer wall of the rotating shaft. A first motor is fixedly disposed on the bottom inner wall of the mounting box. A worm gear is rotatably connected inside the lamp post. The output end of the first motor is fixedly connected to the worm gear. A transmission rod is rotatably connected inside the mounting box between the rope storage wheel and the worm gear. A worm wheel and a first driving gear are fixedly sleeved on the outer wall of the transmission rod. The worm wheel meshes with the worm gear, and the first driving gear meshes with the first driven gear.

[0014] In one possible design, the limiting component includes a limiting block with a groove on one side. The groove is slidably connected to a limiting plate. Two balls are embedded in the inner walls of both sides of the groove. The four balls extend into corresponding grooves and are slidably connected to the inner walls of the grooves. A limiting screw is fixedly connected to the end of the limiting block away from the lamp post. The limiting screw passes through the lamp frame and is slidably connected to the lamp frame. A nut is threaded onto one end of the limiting screw.

[0015] In one possible design, a spring is fitted onto one end of the limiting screw near the nut, with the two ends of the spring respectively abutting against one side of the nut and the lamp holder.

[0016] In one possible design, the support assembly includes a support rod that is rotatably connected to the lamp post via a rotating seat. A slider is slidably fitted on the outer wall of the support rod. A connecting shaft is rotatably connected to the top of the slider. A threaded rod is fixedly connected to the top of the connecting shaft. The threaded rod's top end threadedly passes through the mounting plate and extends above the mounting plate. A drive assembly for driving the threaded rod to rise and fall is fixedly installed on the top of the mounting plate.

[0017] In one possible design, the drive assembly includes a second driven gear rotatably connected to the top of the mounting plate, a threaded rod threaded through the second driven gear, a second motor fixedly mounted on the top of the mounting plate by a mounting bracket, a second drive gear fixedly fitted at the output end of the second motor, and the second drive gear meshing with the second driven gear.

[0018] In one possible design, the top of the support rod has a corresponding slot for the lamp holder, and the lamp holder is engaged with the slot.

[0019] In this application, firstly, a lamp holder with a light installed is placed on a lamp post. Then, the lamp post is erected and fixed. Then, the first motor in the lifting assembly drives the worm gear to rotate. The worm gear drives the worm wheel and the transmission rod to rotate, thereby driving the first driving gear to mesh with the first driven gear, causing the rope storage wheel to rotate and store or release the lifting rope, thereby driving the connecting plate and the connecting rope fixed thereto to rise and fall, and finally realizing the lifting and adjustment of the lamp holder.

[0020] Among them, the sliding connection between the limiting block and the limiting plate of the limiting component, and the sliding connection between the limiting screw and the lamp holder, realize the stable limiting of the lamp holder during the lifting process and prevent shaking. The setting of the ball reduces sliding friction and improves the flexibility and durability of the limiting component.

[0021] When the lamp holder is raised to the required height, the second motor in the support assembly drives the second drive gear and the second driven gear to mesh, causing the threaded rod to rotate and drive the slider and support rod to rotate along the outer wall of the lamp post to a suitable angle. Then, the lamp holder is secured by the slot at the top of the support rod to achieve further fixation and support.

[0022] The PLC control box is responsible for receiving control signals and driving the operation of each component. At the same time, the protective cover effectively protects the lighting device from the influence of the external environment.

[0023] Beneficial effects: In this utility model, the urban environmental lighting device realizes the lifting and adjustment of the lamp holder through a motor drive and gear transmission mechanism. The structure is simple and the operation is convenient, reducing the difficulty of installation and maintenance.

[0024] In this utility model, the urban environmental lighting device achieves stable positioning of the lamp holder during the lifting and lowering process by sliding the connecting limiting block and the limiting plate in the limiting component through the sliding connection of the limiting block and the limiting plate in the limiting component;

[0025] In this utility model, the urban environmental lighting device provides additional support for the lamp holder located at a high altitude through the setting of the support component, preventing the lamp holder from accidentally slipping down when the rope is damaged.

[0026] In this invention, the lifting and lowering of the lamp holder is achieved through a motor drive and gear transmission mechanism. Its structure is simple and easy to operate, reducing the difficulty of installation and maintenance. The limiting block in the limiting component is slidably connected to the sliding groove of the limiting plate to achieve stable limiting of the lamp holder during the lifting and lowering process and prevent shaking. The setting of the support component provides additional support for the lamp holder located at high altitude and prevents the lamp holder from accidentally slipping when the rope is damaged.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1: Refer to Figure 1-5 A lighting device includes a lamp post 1, which is designed with a hollow structure to facilitate the arrangement of internal components. A mounting base 2 is fixedly mounted at the bottom of the lamp post 1 for securing the device to the ground. Above the mounting base 2, a mounting opening is provided on the lamp post 1 for easy installation, and a sealing door is hinged to this opening to protect the electrical components inside the lamp post 1. A PLC control box 16 is housed inside the sealing door for controlling the operation of the entire lighting device.

[0035] A lamp holder 3 is slidably fitted onto the outer wall of the lamp post 1. Multiple lighting lamps 6 are fixedly mounted on the lamp holder 3 at equal intervals via mounting brackets to provide illumination for the urban environment. A mounting plate 7 is provided at the top of the lamp post 1. The mounting plate 7 has an opening that communicates with the interior of the lamp post 1 for the passage of ropes 9. A protective cover 4 is fixedly installed on the top of the mounting plate 7 to protect the electrical and mechanical components at the top.

[0036] Two limiting plates 5 are symmetrically fixed to the outer wall of the lamp post 1. Each limiting plate 5 has two symmetrical grooves on both sides to engage with the limiting components and restrict the swaying of the lamp holder 3. Three multi-wheel guide groups 8 are fixedly installed at equal intervals on the top of the mounting plate 7. Each multi-wheel guide group 8 includes two support plates, with two guide wheels rotatably connected between them. Connecting ropes 9 are laid on the corresponding guide wheels to achieve stable guidance and support.

[0037] One end of each of the three connecting ropes 9 is fixedly connected to the lamp holder 3, and the other end extends into the interior of the lamp post 1 and is fixedly connected to the top of the connecting plate 10. In this way, when the connecting plate 10 is raised or lowered, the lamp holder 3 can be raised or lowered by the connecting ropes 9.

[0038] To achieve the raising and lowering of the lamp holder 3, a raising assembly is installed inside the lamp post 1. This raising assembly includes a mounting box, which is fixedly installed at the mounting opening inside the lamp post 1. Inside the mounting box, a rope storage wheel 11 is rotatably connected via a rotating shaft, and a raising rope 17 is wound around the rope storage wheel 11. One end of the raising rope 17 is fixedly connected to the bottom of the connecting disc 10. A first driven gear 12 is fixedly sleeved on the outer wall of the rotating shaft. A first motor 14 is fixedly installed on the bottom inner wall of the mounting box, and the output end of the first motor 14 is fixedly connected to a worm gear 28. Inside the mounting box, a transmission rod is rotatably connected between the rope storage wheel 11 and the worm gear 28. A worm wheel 13 and a first driving gear 15 are fixedly sleeved on the outer wall of the transmission rod. The worm wheel 13 meshes with the worm gear 28, and the first driving gear 15 meshes with the first driven gear 12. When the first motor 14 starts, the worm gear 28, worm wheel 13, transmission rod, first driving gear 15 and first driven gear 12 drive the rope storage wheel 11 to rotate, thereby raising and lowering the lifting rope 17 and realizing the raising and lowering of the connecting plate 10 and the lamp holder 3.

[0039] To prevent the lamp holder 3 from swaying during lifting and lowering, two sets of limiting components are also provided on the corresponding limiting plate 5. Each limiting component includes a limiting block 18, with a sliding groove on one side of the limiting block 18, which is slidably connected to the limiting plate 5. Two ball bearings are embedded in the inner walls of both sides of the sliding groove. These four ball bearings extend into the corresponding grooves and roll in contact with the inner walls of the grooves to reduce friction. A limiting screw 19 is fixedly connected to the end of the limiting block 18 away from the lamp post 1. The limiting screw 19 passes through the lamp holder 3 and is slidably connected to the lamp holder 3. A nut is threaded onto one end of the limiting screw 19 to fix the limiting block 18 and the lamp holder 3 together.

[0040] Secondly, to support and further secure the lamp holder 3 when raised to the required height, two sets of support assemblies are symmetrically arranged on the outer wall of the lamp post 1. Each set of support assemblies includes a support rod 21, which is rotatably connected to the lamp post 1 via a rotating seat. A slider 22 is slidably sleeved on the outer wall of the support rod 21, and a connecting shaft 23 is rotatably connected to the top of the slider 22. A threaded rod 24 is fixedly connected to the top of the connecting shaft 23, and the threaded end of the threaded rod 24 passes through the mounting plate 7 and extends above the mounting plate 7. A drive assembly for driving the threaded rod 24 to rise and fall is fixedly arranged on the top of the mounting plate 7.

[0041] The drive assembly includes a second driven gear 25 and a second motor 26. The second driven gear 25 is rotatably connected to the top of the mounting plate 7, and a threaded rod 24 is threaded through the second driven gear 25. The second motor 26 is fixedly mounted on the top of the mounting plate 7 via a mounting bracket, and a second driving gear 27 is fixedly fitted onto its output end. The second driving gear 27 is meshed with the second driven gear 25. When the second motor 26 is started, it can drive the second driven gear 25 and the threaded rod 24 to rise and fall, thereby driving the slider 22, the connecting shaft 23, and the support rod 21 to rotate and rise and fall, thus supporting and fixing the lamp holder 3.

[0042] This application can be used in the field of urban lighting technology, or in other fields applicable to this application.

[0043] Example 2: Reference Figure 3-5 An improvement based on Embodiment 1: An urban environmental lighting device, applied in the field of urban lighting technology, includes a spring 20 fitted onto the end of the limiting screw 19 near the nut. The two ends of the spring 20 respectively abut against one side of the nut and the lamp holder 3. Thus, when the lamp holder 3 rises or falls, the spring 20 provides a certain buffering effect, protecting the lamp holder 3 and the limiting assembly from damage.

[0044] In addition, in order to support the lamp holder 3 more stably, the present invention also provides a slot corresponding to the lamp holder 3 at the top of the support rod 21. When the lamp holder 3 is raised to the required height, it can be locked in the slot to further improve stability.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 14 and the second motor 26 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
