Description

Technical Field

[0001] This utility model belongs to the field of solar street light technology, and specifically relates to a solar street light with an adjustable illumination angle. Background Technology

[0002] Solar streetlights are devices that utilize solar energy for lighting. They mainly consist of solar panels, batteries, solar controllers, light sources, poles, and lamp housings. They convert received solar energy into electrical energy to power the streetlights. However, the areas where solar streetlights are installed are not uniform. These areas may vary in width, elevation, or be obstructed by vegetation. Commonly used solar streetlights with fixed fixtures cannot adapt to these variations, resulting in an inability to adjust the lamp angle. This limits the illuminated area and may lead to dark areas, making it impossible to adjust the illumination angle adaptably to different road sections. While some existing solar streetlights can adjust the illumination angle, most use exposed mechanical structures such as worm gears and screw systems, which are susceptible to rain corrosion, causing the mechanism to jam and resulting in poor performance.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0027] Please see Figures 1-5 As the first embodiment of this utility model:

[0028] An adjustable illumination angle solar street light includes: a street light frame assembly 100, which includes a lamp post 101, a lifting rack 106 and a solar panel 108.

[0029] A lifting rack 106 for assisting the lifting and moving of the street lamp base assembly 200 is fixedly installed at the upper rear end of the lamp post 101. A top plate 107 is fixedly connected above the lamp post 101. A solar panel 108 for converting solar energy into electrical energy is fixedly connected above the top plate 107. The street lamp base assembly 200 is installed at the upper outer side of the lamp post 101.

[0030] The street light base assembly 200 includes a collar 201, an extension plate 204, a rotating groove 205, an angle adjusting wheel 208, an angle adjusting belt 211, and a lifting gear. The extension plate 204 is fixedly connected to the right side of the collar 201. The right end of the upper surface of the extension plate 204 vertically penetrates to form the rotating groove 205, and the left end of the upper surface of the extension plate 204 vertically penetrates to form a through groove. An angle adjusting wheel 208 for adjusting the angle of the street light body 213 is provided inside the through groove, and an angle adjusting belt 211 is provided outside the angle adjusting wheel 208.

[0031] The inner rear end of the collar 201 is fixedly connected to a lifting gear via a lifting motor. The lifting gear meshes with the lifting rack 106. A set of rotating shafts is fixedly connected to both the front and rear sides of the angle adjustment wheel 208. An angle adjustment motor is fixedly connected to the front of the front rotating shaft. The lifting gear is driven by the lifting motor to rotate along the lifting rack 106, thereby driving the street light base assembly 200 to lift and adjust the auxiliary light illumination angle.

[0032] The angle adjusting wheel 208 is a toothed pulley, and the angle adjusting belt 211 is a synchronous toothed belt. The angle adjusting wheel 208 and the angle adjusting belt 211 mesh with each other. An angle adjusting shaft 206 is rotatably connected to the inner side of the rotating groove 205. A set of connecting rods 207 are fixedly connected to both the upper and lower ends of the angle adjusting shaft 206.

A connecting frame is fixedly connected to the right side of the angle adjusting shaft 206. The street light body 213 is fixedly connected to the right side of the connecting frame. The angle adjusting motor drives the angle adjusting wheel 208 to rotate, which in turn pulls the angle adjusting belt 211 to rotate in the forward direction. Through the interlocking of the hooks 212, the angle adjusting shaft 206 rotates in both directions, thus completing the angle adjustment of the street light body 213.

[0034] A lifting seat 102 is fixedly connected to the upper rear end of the lamp post 101. A set of guide grooves 103 are opened on both the left and right ends of the lower surface of the lifting seat 102. A guide slider 202 is fixedly connected to the inner rear end of the collar 201.

[0036] Specifically, during use, the solar street light adjusts the angle by driving the angle adjustment wheel 208 to rotate according to the actual installation area. This, in turn, pulls the angle adjustment belt 211 to rotate in the forward direction. Through the engagement of the hook 212, the angle adjustment shaft 206 rotates in both directions, thus adjusting the angle of the street light body 213. Furthermore, according to the actual required illumination angle, the lifting motor drives the lifting gear to rotate along the lifting rack 106, thereby raising and lowering the street light base assembly 200 to assist in adjusting the illumination angle. During the raising and lowering movement of the street light base assembly 200, the guide slider 202 slides along the guide groove 103, assisting in the raising and lowering movement of the street light base assembly 200, thereby achieving the effect of adjusting the illumination angle.

[0037] Please see Figures 1-5 As a second embodiment of this utility model:

A sealing ring 210 is fixedly connected to the inside of the through hole and the angle adjustment belt 211 passes through it. The outside of the lifting seat 102 is covered by the bellows cover 203 and moves up and down with the collar 201. The outer end of the angle adjustment wheel 208 is covered by the cover 209. The sealing ring 210 guides the angle adjustment belt 211 through it.

[0041] Based on the first embodiment described above, further, the outer side of the lifting seat 102 is covered by the bellows cover 203 and moves up and down with the collar 201, and the outer end of the angle adjustment wheel 208 is covered by the cover 209. The sealing ring 210 guides the angle adjustment belt 211, so that the lifting and rotation related components are covered and not in direct contact with the external environment, thereby improving the service life of the components.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
