[0030] The outer cross section of the limiting block 32 is the same as the inner cross section of the inner cavity 33 and the cross section is square. The inner bottom of the inner cavity 33 is rotatably connected to the rotating rod 36, and the top of the rotating rod 36 is fixedly installed with the screw 35. A threaded hole 34 is opened between the lifting rod 31 and the interior of the limiting block 32, and the screw 35 is screwed into the threaded hole 34.

[0031] A first bevel gear 37 is fixedly installed on the outer side of the rotating rod 36. An adjusting rod 39 is rotatably connected to the side wall of the bottom column 1.

[0033] In this embodiment, when installing the adjustable illumination angle urban LED street light, the bottom column 1 is first fixedly installed on the pre-cast street light foundation to ensure that the bottom column 1 is installed firmly and vertically. Subsequently, the light pole cylinder 4 is fixedly installed on the top of the bottom column 1, and the top column 5 is fixedly installed on the top of the light pole cylinder 4 to ensure that the connection between the components is tight and stable.

[0035] The lifting block 25 is installed in the inner groove 21 so that it can slide up and down in the inner groove 21. Then, the adjusting rod 23 is hinged to the lifting block 25 through the connecting rod 24. The adjusting rod 23 is fixedly installed on the back of the adjusting block 22 to ensure that the hinge connection between the connecting rod 24, the adjusting rod 23, and the lifting block 25 is reliable and can achieve effective force transmission.

[0036] A support column 6 is fixedly installed on top of the top column 5, and a photovoltaic panel 7 is fixedly installed on top of the support column 6, ensuring that the installation angle of the photovoltaic panel 7 can maximize the absorption of solar energy and improve the utilization rate of solar energy. An equipment box 10 is fixedly installed on the outside of the support column 6, and an energy storage battery module and a controller module are installed inside the equipment box 10. The photovoltaic panel 7 and the energy storage battery module are electrically connected by wires, so that the electrical energy generated by the photovoltaic panel 7 after absorbing solar energy can be stored in the energy storage battery module. At the same time, the energy storage battery module is electrically connected to the LED light 8 through the controller module, and the external wire 11 passes through the inside of the connecting rod 9 and is electrically connected to the LED light 8 to form a complete electrical connection circuit, ensuring that the energy storage battery module can provide a stable power supply to the LED light 8, and the controller module can realize functions such as switching control and brightness adjustment of the LED light 8.

[0037] An internal cavity 33 is formed inside the bottom column 1, and a limiting block 32 is installed inside the internal cavity 33, allowing the limiting block 32 to slide up and down within the internal cavity 33. Since both the outer cross-section of the limiting block 32 and the inner cross-section of the internal cavity 33 are square, rotation of the limiting block 32 during sliding is effectively prevented. A lifting rod 31 is fixedly installed on the top of the limiting block 32, allowing the lifting rod 31 to move through the connection between the bottom column 1 and the lamp post cylinder 4, with its upper end located inside the lamp post cylinder 4. A pull rod 26 is fixedly installed on the top of the lifting rod 31, allowing the top of the pull rod 26 to move through the connection between the lamp post cylinder 4 and the top column 5, and is fixedly installed on the bottom of the lifting block 25, ensuring that the lifting movement of the lifting rod 31 can drive the lifting block 25 to move up and down synchronously via the pull rod 26.

[0038] A rotating rod 36 is rotatably connected to the bottom of the inner cavity 33 via a bearing. A screw 35 is fixedly installed on the top of the rotating rod 36. A threaded hole 34 is opened between the lifting rod 31 and the limiting block 32, and the screw 35 is screwed into the threaded hole 34 to ensure that the rotation of the screw 35 can drive the lifting rod 31 and the limiting block 32 to move up and down. A first bevel gear 37 is fixedly installed on the outside of the rotating rod 36. An adjusting rod 39 is rotatably connected to the side wall of the bottom column 1 via a bearing. A second bevel gear 38 is fixedly installed on the inner end of the adjusting rod 39 so that the second bevel gear 38 meshes with the first bevel gear 37. A crank handle 310 is fixedly installed on the outer end of the adjusting rod 39 so that the operator can control the rotation of the adjusting rod 39 by turning the crank handle 310.

[0039] Finally, a grease with strong adhesion, anti-leakage, wear-resistant and anti-contamination properties is applied to the outside of the screw 35 and the threaded hole 34, as well as the outside of the second bevel gear 38 and the first bevel gear 37, to reduce frictional loss between components, improve the service life of components, and ensure the operational flexibility and reliability of the entire adjustment mechanism.

[0040] Routine maintenance

[0041] Regular cleaning: Regularly clean the surface of the photovoltaic panel 7 to remove dust, dirt, leaves, and other debris, ensuring that the photovoltaic panel 7 can properly receive solar energy and improve power generation efficiency. At the same time, regularly clean the lampshade of the LED light 8 to remove dust and stains from the surface of the lampshade, ensuring the lighting effect of the LED light 8.

[0042] Lubrication inspection and replenishment: Regularly check the grease condition on the outside of the screw 35 and threaded hole 34, as well as the outside of the second bevel gear 38 and the first bevel gear 37. If grease loss, drying or severe contamination is found, the old grease should be cleaned in time and a new grease with strong adhesion, anti-loss, wear resistance and anti-contamination should be applied to ensure the normal operation of each transmission component.

[0043] Component fastening inspection: Regularly check the tightness of the connections between components, such as whether the bolts and nuts at the connection points between the bottom column 1 and the lamp post cylinder 4, the lamp post cylinder 4 and the top column 5, the adjusting block 22 and the connecting rod 9, and the LED light 8 and the connecting rod 9 are loose. If any looseness is found, tighten them in time to prevent the components from falling off and to ensure the structural stability and safety of the street light.

[0044] Electrical System Inspection: Regularly inspect the energy storage battery module, controller module, and all wiring connections inside equipment box 10. Check if the energy storage battery module has sufficient power, if the controller module is working properly, and if the wiring connections are secure and free from damage or aging. If any problems are found, repair or replace them promptly to ensure the normal operation of the electrical system and guarantee a stable power supply to LED lights 8.

[0045] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0046] Working Principle: When the operator arrives at the LED streetlight requiring adjustment, confirms the surrounding environment is safe and free of obstacles, and prepares to adjust the illumination angle. The operator holds the crank handle 310 and rotates it in the desired direction. To tilt the LED light 8 upwards, the crank handle 310 is rotated clockwise; to tilt it downwards, it is rotated counter-clockwise. The rotation of the crank handle 310 causes the adjusting rod 39 to rotate synchronously. Because the second bevel gear 38, fixedly mounted on the inner end of the adjusting rod 39, meshes with the first bevel gear 37, fixedly mounted on the outer side of the rod 36, the rotation of the adjusting rod 39 drives the rotating rod 36 to rotate through the meshing transmission of the bevel gears. The rotation of the rotating rod 36 drives the screw 35, which is fixedly installed on its top, to rotate synchronously. The screw 35 is screwed into the threaded hole 34 inside the lifting rod 31 and the limiting block 32. Since the outer cross-section of the limiting block 32 and the inner cross-section of the inner cavity 33 are both square, the limiting block 32 cannot rotate. Therefore, the rotation of the screw 35 is converted into the up-and-down movement of the lifting rod 31 and the limiting block 32 along the inner cavity 33. When the crank handle 310 is turned clockwise, the screw 35 rotates clockwise, driving the lifting rod 31 and the limiting block 32 to move upward; when the crank handle 310 is turned counterclockwise, the screw 35 rotates counterclockwise, driving the lifting rod 31 and the limiting block 32 to move downward. The up-and-down movement of the lifting rod 31 drives the lifting block 25 to slide synchronously up and down in the inner groove 21 through the pull rod 26 fixedly installed on its top. When the lifting block 25 slides upward, the hinged connecting rod 24 pulls the adjusting rod 23, causing the adjusting rod 23 to drive the adjusting block 22 to rotate upward around its rotational connection point with the internal groove 21. When the lifting block 25 slides downward, the hinged connecting rod 24 pushes the adjusting rod 23, causing the adjusting rod 23 to drive the adjusting block 22 to rotate downward around its rotational connection point with the internal groove 21. The rotation of the adjusting block 22 causes the connecting rod 9 fixedly mounted on its front and the LED light 8 to rotate synchronously, thereby adjusting the illumination angle of the LED light 8. While rotating the crank handle 310, the operator observes the illumination range and angle of the LED light 8. When the desired illumination angle is reached, the operator stops rotating the crank handle 310. Because the thread lead angle between the screw 35 and the threaded hole 34 is less than the equivalent friction angle, the screw 35 and the threaded hole 34 have a self-locking function, which prevents the lifting rod 31 from sliding on its own after the crank handle 310 is stopped, thus ensuring that the LED light 8 can be stably maintained at the adjusted illumination angle position, completing the entire illumination angle adjustment operation.
