The bulb 105 provides the necessary lighting function, and the lampshade 106 protects the bulb and effectively diffuses the light, improving the lighting effect of the surrounding environment. The design of the snap-on assembly 107 enables the lampshade 106 to be firmly fixed to the bottom end of the mounting plate 104. At the same time, the connection between the lampshade and the bulb also facilitates the removal and replacement of the lampshade, thereby improving the maintenance convenience of the lighting device.

[0030] The lifting mechanism 200 includes a servo motor 201 fixedly mounted at the bottom end of the fixed column 101. The output end of the servo motor 201 is connected to a screw rod 202 through a coupling transmission. The outer surface of the upper end of the screw rod 202 is threadedly connected to a first lifting block 203. The right end of the first lifting block 203 penetrates the inner wall of the fixed column 101 and extends to the outside thereof to be fixedly connected to the lamp pole 102. An auxiliary support assembly 204 is arranged below the first lifting block 203. The lifting mechanism 200 is used to drive the screw rod 202 to rotate through the servo motor 201. The screw rod 202 drives the first lifting block 203 to move up and down, thereby driving the lamp pole 102 to move up and down. Through the design of the lifting mechanism, the lampshade 106 and the light bulb 105 can be lifted and lowered together with the lamp pole, which is convenient for the staff to replace and repair the light bulb.

[0034] A slide groove 103a is provided inside the connecting column 103, and through grooves 103b are symmetrically provided on the left and right sides of the slide groove 103a. The bottom end of the threaded rod 310 penetrates the bottom wall of the lamp pole 102 and extends into the connecting column 103. The slider 311 and the connecting block 312 are both slidably connected in the slide groove 103a, and the opposite ends of the two connecting blocks 312 penetrate the two through grooves 103b and are fixedly connected to the inner wall of the sliding sleeve 107a. The design of the slide groove 103a enables the slider 311 to slide smoothly therein, ensuring the vertical lifting of the lamp pole and the lampshade. Through the cooperation of the connecting block 312 and the sliding sleeve 107a, the stability of the slider and the clamping assembly is ensured, while avoiding interference from other components.

The design of the mounting cavity allows the driving wheel 304, the belt 305 and the driven wheel 306 to maintain smooth movement during movement, ensuring that there is no resistance or jamming during the driving process.

[0036] Bearings 314 are installed on both the left and right sides of the lamp post 102, and the shaft 303 and the rod 307 are rotatably connected to the inner wall of the lamp post 102 through the bearings 314. The design of the bearings 314 ensures that the shaft 303 and the rod 307 can rotate smoothly, reduce friction and extend the service life. Their cooperation ensures that each component can operate smoothly during operation, thereby improving the stability and reliability of the entire device.

[0037] Working principle of this device:

[0038] When the light bulb 105 needs to be removed, the servo motor 201 is started, and the servo motor 201 can drive the screw rod 202 to rotate, and the screw rod 202 can drive the first lifting block 203 and the second lifting block 204a to move vertically downward, and the first lifting block 203 can drive the lamp pole 102 to move downward, and the second lifting block 204a can support the lamp pole 102 to move downward synchronously through the arc support rod 204b, and the lamp pole 102 can drive the unlocking mechanism 300 as a whole and the connecting column 103, the mounting plate 104, the light bulb 105, the lampshade 106, and the clamping assembly 107 to move downward. During the downward movement, when the gear 302 inside the lamp pole 102 is aligned with the support column When the tooth plate 301 on the right side of 101 is engaged, the gear 302 rotates, and the gear 302 can drive the driving wheel 304 to rotate through the rotating shaft 303, and the driving wheel 304 can drive the belt 305 to operate, and the belt 305 can drive the driven wheel 306 on the right side to rotate, and the driven wheel 306 can drive the driving conical teeth 308 to rotate through the rotating rod 307, and the driving conical teeth 308 can drive the driven conical teeth 309 to rotate, and the driven conical teeth 309 can drive the threaded rod 310 to rotate, and the threaded rod 310 can drive the slider 311 to move vertically downward inside the slide groove 103a, and the slider 311 can drive the outer side through the connecting blocks 312 on both sides. The sliding sleeve 107a slides downward along the surface of the connecting column 103, and the sliding sleeve 107a can drive the bottom lampshade to move vertically downward through the lifting frames 107b on both sides. When the lamp pole 102 moves to the bottom of the supporting column 101, the gear 302 also moves to the bottom of the tooth plate 301, and the slider 311 can move to the bottom of the slide groove 103a, and the lifting frame 107b can drive the lampshade 106 to release the protection of the bulb 105. At this time, the staff can directly remove the bulb 105 for replacement or maintenance. After the maintenance and replacement is completed, the servo motor 201 is started again, and the servo motor 201 drives the screw rod 202 to rotate in the opposite direction. The first lifting block 203 and the auxiliary support assembly 204 are driven to move vertically upward, and the first lifting block 203 and the auxiliary support assembly 204 drive the lamp pole 102 and the lighting assembly (including the connecting column 103, the mounting plate 104, the bulb 105, the lampshade 106 and the clamping assembly 107) to move upward as a whole, and the gear 302 meshing with the tooth plate 301 can rotate in the opposite direction, and the threaded rod 311 also rotates in the opposite direction, and the lifting frame 107b can drag the lampshade 106 to move vertically upward. After the gear 302 is separated from the tooth plate 301, the lampshade 106 can completely cover the bulb 105, thereby completing the inspection and installation of the bulb 105.

[0039] Through the close coordination of the above-mentioned components, the urban intelligent lighting device of the present invention can significantly simplify the maintenance operations of traditional lighting devices, especially the replacement of light bulbs and lampshades. The device avoids the risks of high-altitude operations and greatly improves the convenience and safety of maintenance through the lifting and unlocking linkage mechanism. Especially when replacing and repairing light bulbs, workers do not need to climb high and can directly operate the control components at the bottom of the lamp, which greatly improves maintenance efficiency and reduces labor costs. In addition, the design of the entire device takes into account structural stability and the coordination of components to ensure high efficiency and reliability in long-term operation.
