An easy-to-maintain LED solar street light

Abstract

This utility model discloses an LED solar street light that is easy to maintain, including a supporting base cylinder with a groove at the top. An outer telescopic cylinder is inserted into the groove. This easy-to-maintain LED solar street light allows for control of the rotation of the rotating cylinder by controlling the engagement and disengagement of the arc-shaped toothed plate connected to the pressure plate and the toothed pressure plate. This allows the outer telescopic cylinder to be slowly rotated and lowered, reducing the height of the solar LED light panel connected to the telescopic vertical cylinder to a suitable maintenance height. This enables maintenance personnel to quickly inspect the solar LED light panel from the ground. Furthermore, by controlling the rotation of the adjusting cylinder, the threaded displacement between the adjusting cylinder and the telescopic vertical cylinder can be adjusted to a shorter joint length, further facilitating maintenance of the solar LED light panel.

Description

Technical Field

[0001] This utility model relates to the field of street light technology, specifically to an LED solar street light that is easy to maintain. Background Technology

[0002] Solar streetlights are independent power supply systems that convert solar energy into electrical energy using solar panels, store it in batteries, and provide illumination via LED light sources. They are primarily used as environmentally friendly lighting devices to replace traditional electric streetlights, providing illumination for passing vehicles. Currently, existing LED solar streetlights are inconvenient to maintain. They require specialized ladders to transport maintenance personnel to the same height as the solar LED panels, or maintenance personnel need to wear climbing equipment to reach a suitable height. Both methods are time-consuming, labor-intensive, inconvenient, and pose certain safety hazards. Therefore, to address these issues, this application proposes an LED solar streetlight that is easy to maintain. Maintenance of the solar LED panels can be performed simply by standing on the roadside, simplifying operation, reducing the workload for maintenance personnel, and significantly improving maintenance efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an LED solar street light that is easy to maintain, thus solving the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an LED solar street light that is easy to maintain, comprising a supporting base tube, a groove on the top of the supporting base tube, openings on both sides of the groove, an outer telescopic tube inserted into the groove on the top of the supporting base tube, a lock box fixedly installed on the front of the supporting base tube, a rotating shaft tube fixedly passing through the bottom end of the outer telescopic tube, the surface of the rotating shaft tube being rotatably connected to the inner wall of the groove of the supporting base tube, the front end of the rotating shaft tube passing through the front of the supporting base tube and extending into the interior of the lock box, a telescopic vertical tube inserted into the top of the rotating shaft tube, a rectangular positioning support column inserted into the bottom of the telescopic vertical tube, the bottom end of the rectangular positioning support column being fixedly connected to the inner wall of the rotating shaft tube, and a solar LED light panel fixedly installed on the top of the telescopic vertical tube.

[0005] Preferably, an adjusting cylinder is rotatably connected to the top edge of the rotating shaft cylinder, a threaded groove is formed on the surface of the telescopic vertical cylinder, the inner ring of the adjusting cylinder is threadedly sleeved on the surface of the telescopic vertical cylinder, an external gear cylinder is fixedly connected to the bottom of the adjusting cylinder, the inner ring of the external gear cylinder is sleeved on the surface of the rotating shaft cylinder, a positioning internal gear cylinder is slidably sleeved on the surface of the rotating shaft cylinder, the bottom of the external gear cylinder extends into the interior of the positioning internal gear cylinder, and the teeth on the surface of the external gear cylinder engage with the tooth grooves of the inner ring of the positioning internal gear cylinder.

[0006] Preferably, a fixed pressure plate is fixedly sleeved on the surface of the rotating shaft cylinder, and two threaded adjusting rods penetrate the surface of the fixed pressure plate. The surface of the threaded adjusting rods is threadedly sleeved with the inner wall of the fixed pressure plate, and the tops of the two threaded adjusting rods are rotatably connected to the lower surface of the positioning inner gear cylinder.

[0007] Preferably, the lock box is internally provided with two connecting rods and two pressure plates. The two ends of the connecting rods are fixedly connected to the front of the support base cylinder. The surfaces of the two connecting rods penetrate the inner walls of the two pressure plates. The surface of the right connecting rod is threaded with two drive threaded caps. The two drive threaded caps are rotatably connected to the surfaces of the two pressure plates respectively. The rotating shaft cylinder is fixedly fitted with a toothed pressure plate on its internal surface. The inner sides of the two pressure plates are fixedly provided with arc-shaped toothed plates. The tooth grooves of the arc-shaped toothed plates mesh with the teeth of the toothed pressure plates.

[0008] Preferably, rectangular limiting protrusions are fixedly provided on both the front and back sides of the outer ring of the rotating shaft cylinder, and the surface of the rectangular limiting protrusions is slidably connected to the inner wall of the positioning inner tooth cylinder.

[0009] This invention provides an LED solar street light that is easy to maintain. It has the following advantages: (1) This easy-to-maintain LED solar street light, by rotating the two drive threaded caps inside the lock box, causes the two pressure plates to move outward vertically inside the lock box. That is, the arc-shaped toothed plate connected to the pressure plate and the toothed pressure plate are disengaged, so the rotating cylinder is in a rotatable state. At this time, its outer telescopic cylinder can be slowly rotated and lowered, so that the solar LED light panel connected to the telescopic vertical cylinder is lowered to a suitable maintenance height. This allows maintenance personnel to quickly maintain the solar LED light panel on the ground. At the same time, the position of the positioning inner toothed cylinder in the vertical direction can be adjusted by the threaded adjustment rod, so that it can pass through the outer toothed cylinder and the positioning inner toothed cylinder. The sleeve engages and controls the rotation of the adjusting drum. When the adjusting drum can rotate, the threaded displacement between the adjusting drum and the surface of the telescopic vertical tube, as well as the constraint of the rectangular positioning support column inside the telescopic vertical tube in the direction of rotation, allow the telescopic vertical tube to extend and retract inside the outer telescopic tube. This adjusts the splicing length of the outer telescopic tube and the telescopic vertical tube to a shorter length, preventing the lamp post from being too long after the outer telescopic tube is rotated and laid down, which would seriously affect the normal order of the site during maintenance. This facilitates rapid on-site maintenance, making it more convenient for maintenance personnel to operate the solar LED light panel, reducing the difficulty of their work, and greatly improving maintenance efficiency.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] like Figure 1-9As shown, this utility model provides a technical solution: an LED solar street light that is easy to maintain, including a support base cylinder 1. The top of the support base cylinder 1 has a groove, and openings are provided on both sides of the groove. An outer telescopic cylinder 2 is inserted into the groove at the top of the support base cylinder 1. A lock box 13 is fixedly installed on the front of the support base cylinder 1. The lock box 13 serves to lock the positioning mechanism that controls the rotation of the rotating shaft cylinder 3, preventing unauthorized personnel from knocking down the light pole. The bottom end of the outer telescopic cylinder 2 is fixedly inserted through the rotating shaft cylinder 3. The surface of the rotating shaft cylinder 3 is rotatably connected to the inner wall of the groove in the support base cylinder 1. The front end of the rotating shaft cylinder 3 passes through the front of the support base cylinder 1 and extends into the interior of the lock box 13. A telescopic vertical cylinder 4 is inserted into the top of the rotating shaft cylinder 3, and a rectangular positioning support column 5 is inserted into the bottom of the telescopic vertical cylinder 4. The bottom end of the rectangular positioning support column 5 is fixedly connected to the inner wall of the rotating shaft cylinder 3. The rectangular positioning support column 5 ensures that the telescopic vertical cylinder 4 is more stable when it extends and retracts inside the outer telescopic cylinder 2, and also fixes the rotation direction of the telescopic vertical cylinder 4. A solar LED light panel 12 is fixedly installed on the top of the telescopic vertical cylinder 4. An adjusting rotating cylinder 6 is rotatably connected to the top edge of the rotating shaft cylinder 3. The surface of the telescopic vertical cylinder 4 has a threaded groove. The inner ring of the adjusting rotating cylinder 6 is threaded onto the surface of the telescopic vertical cylinder 4. By adjusting the rotating cylinder 6, the telescopic movement is achieved by adjusting the threaded groove between the rotating cylinder 6 and the surface of the telescopic vertical cylinder 4. The displacement is adjusted to shorten the splicing length of the outer telescopic cylinder 2 and the telescopic vertical cylinder 4, preventing the lamp post from being too long after the outer telescopic cylinder 2 is rotated and lowered, which would seriously affect the normal order of the site during maintenance, so as to facilitate rapid on-site maintenance and make the on-site work smoother. The bottom of the adjusting cylinder 6 is fixedly connected to the outer toothed cylinder 7. The inner ring of the outer toothed cylinder 7 is sleeved on the surface of the rotating shaft cylinder 3. The surface of the rotating shaft cylinder 3 is slidably fitted with the positioning inner toothed cylinder 8. The bottom of the outer toothed cylinder 7 extends into the interior of the positioning inner toothed cylinder 8, and the teeth on the surface of the outer toothed cylinder 7 are engaged with the tooth grooves of the inner ring of the positioning inner toothed cylinder 8. Rectangular limiting protrusions 9 are fixedly provided on the front and back of the outer ring of the rotating shaft cylinder 3. The surface of the rectangular limiting protrusions 9 is slidably connected to the inner wall of the positioning inner toothed cylinder 8. The limiting protrusion 9 ensures that the positioning inner gear cylinder 8 can slide and engage vertically on the surface of the rotating shaft cylinder 3, but cannot rotate in the rotational direction. A fixed pressure plate 10 is fixedly fitted onto the surface of the rotating shaft cylinder 3, and two threaded adjusting rods 11 pass through the surface of the fixed pressure plate 10. The surfaces of the threaded adjusting rods 11 are threadedly engaged with the inner wall of the fixed pressure plate 10, and the tops of the two threaded adjusting rods 11 are rotatably connected to the bottom surface of the positioning inner gear cylinder 8. Through the setting of the fixed pressure plate 10 and the threaded adjusting rods 11, the position of the positioning inner gear cylinder 8 in the vertical direction of the rotating shaft cylinder 3 can be controlled at any time, that is, whether the positioning inner gear cylinder 8 and the outer gear cylinder 7 are engaged, thereby controlling the rotation of the adjusting cylinder 6.The lock box 13 is internally equipped with two connecting rods 14 and two pressure plates 15. The two ends of the connecting rods 14 are bent and fixedly connected to the front of the support base cylinder 1. The surfaces of the two connecting rods 14 penetrate the inner walls of the two pressure plates 15. Two threaded caps 18 are threaded onto the surface of the right connecting rod 14, and these caps 18 are rotatably connected to the surfaces of the two pressure plates 15. A toothed pressure plate 16 is fixedly fitted onto the surface of the rotating shaft cylinder 3 inside the lock box 13. Arc-shaped toothed plates 17 are fixedly installed on the inner sides of the two pressure plates 15, and the tooth grooves of the arc-shaped toothed plates 17 mesh with the teeth of the toothed pressure plates 16. This connection is achieved through the connecting rods 14 and the pressure plates 15. The arrangement of the toothed pressure plate 15, the arc-shaped toothed plate 17, and the threaded cap 18 allows the threaded cap 18 to rotate, causing the two pressure plates 15 to move vertically outward within the lock box 13. This disengages the arc-shaped toothed plate 17 (connected to the pressure plate 15) from the toothed pressure plate 16, enabling the rotating shaft 3 to rotatably. This allows the outer telescopic cylinder 2 to be slowly rotated and lowered, reducing the solar LED light panel 12 connected to the telescopic vertical cylinder 4 to a suitable maintenance height. This allows maintenance personnel to quickly inspect the solar LED light panel 12 from the ground, improving maintenance efficiency.

[0014] In use, first open the lock box 13, then rotate the two drive threaded caps 18 inside, causing them to drive the two pressure plates 15 to move outward vertically inside the lock box 13. This disengages the arc-shaped toothed plate 17 connected to the pressure plate 15 from the toothed pressure plate 16. At this time, the rotating shaft cylinder 3 is in a rotatable state. After slowly rotating and lowering its outer telescopic cylinder 2 to a horizontal position, maintenance personnel can stand on the ground to inspect the solar LED light panel 12. When it is necessary to adjust the length of the light pole according to the site environment, the two drive threaded caps 18 can be rotated in the opposite direction to reset the two arc-shaped toothed plates 17 to re-engage with the toothed pressure plate 16. The rotation state of the rotating cylinder 3 is fixed, and then the two threaded adjusting rods 11 are rotated to drive the positioning inner gear cylinder 8 to move downward, so that the positioning inner gear cylinder 8 and the outer gear cylinder 7 are disengaged. Then the adjusting cylinder 6 can be rotated for adjustment. By adjusting the threaded telescopic displacement of the rotating cylinder 6 and the surface of the telescopic cylinder 4, the splicing length of the outer telescopic cylinder 2 and the telescopic cylinder 4 is adjusted to a shorter length to prevent the lamp post length after the outer telescopic cylinder 2 is rotated and laid down from being too long and seriously affecting the normal order of the site during maintenance, so as to facilitate rapid on-site maintenance. At the same time, the contents not described in detail in this manual are all existing technologies known to those skilled in the art.

[0015] In summary, this easy-to-maintain LED solar street light, by rotating the two threaded caps 18 inside the lock box 13, causes the two pressure plates 15 to move outward vertically within the lock box 13. This disengages the arc-shaped toothed plate 17 connected to the pressure plate 15 from the toothed pressure plate 16, thus allowing the rotating shaft cylinder 3 to rotatably. At this point, its outer telescopic cylinder 2 can be slowly rotated and lowered, reducing the solar LED light panel 12 connected to the telescopic vertical cylinder 4 to a suitable maintenance height. This allows maintenance personnel to quickly inspect the solar LED light panel 12 from the ground. Simultaneously, the threaded adjusting rod 11 allows for adjustable positioning of the inner toothed cylinder 8 in the vertical direction, enabling it to pass through the outer toothed cylinder 7 and... The positioning inner gear cylinder 8 engages with the sleeve, controlling the rotation of the adjusting cylinder 6. When the adjusting cylinder 6 can rotate, the screw-on displacement between the adjusting cylinder 6 and the surface of the telescopic cylinder 4, as well as the rectangular positioning support column 5 inside the telescopic cylinder 4, constrain the rotation direction, allowing the telescopic cylinder 4 to extend and retract inside the outer telescopic cylinder 2. This adjusts the splicing length of the outer telescopic cylinder 2 and the telescopic cylinder 4 to a shorter length, preventing the lamp post from being too long after the outer telescopic cylinder 2 is rotated and laid down, which would seriously affect the normal order of the site during maintenance. This facilitates quick on-site maintenance, making it more convenient for maintenance personnel to operate the solar LED light panel 12, reducing the difficulty of their work, and greatly improving maintenance efficiency.
