[0002] Angle-adjustable solar street lights usually consist of solar panels, lamp body, lamp frame, battery and controller.

[0003] Patent announcement number CN220750033U relates to an angle-adjustable solar street light, comprising a base, a support rod, a mounting base, an angle adjustment structure, and a solar power generation structure. The support rod is mounted on the base, the mounting base is mounted on the support rod, the angle adjustment structure is mounted on the mounting base, and the solar power generation structure is mounted on the mounting base. The angle adjustment structure comprises a first fixing base, a support frame, a rotating base, a rotating base, a first LED lamp, a second fixing base, a telescopic adjustment column, a rotating adjustment rod, a support column, and a second LED lamp. This patent belongs to the technical field of solar street light equipment, specifically referring to an angle-adjustable solar street light. It effectively solves the problem of solar street lights currently on the market, which requires workers to climb to the top to operate when adjusting the lighting angle. Working at height is risky, and when adjusting the solar street light's illumination angle from above, it is impossible to accurately determine whether the optimal lighting effect has been achieved. Two people are required to operate, one to observe and the other to adjust, wasting labor and posing high safety risks.

[0004] The above patent effectively solves the problem that when adjusting the lighting angle of solar street lights on the current market, workers need to climb to the top to operate, which is risky to work at height. Moreover, when adjusting the illumination angle of the solar street lights from above, it is impossible to accurately determine whether the best lighting effect is achieved. Two people are required to operate, one to observe and the other to adjust, which wastes manpower and has high safety risks. However, it is difficult to prevent the angle of the solar street lights from being accidentally adjusted due to accidental touch by personnel during maintenance. If the angle of the solar panel is not appropriate due to accidental touch by personnel, the solar panel will reduce the absorption of light energy, affect the charging of the battery, and shorten the lighting time.

[0014] The present invention provides an angle-adjustable solar street light, which has the following beneficial effects:

[0015] (1) For this angle-adjustable solar street light, when the angle of the lamp body or solar panel needs to be adjusted, the user must first manually pull the U-shaped rod to move it out of contact with the protective hole and release the limit on the adjustment rod. By setting the U-shaped rod to prevent people from making mistakes, the solar panel can always be kept at the best angle, ensuring maximum light energy absorption, improving battery charging efficiency and the lighting time of the lamp body. After the limit of the lamp pole is released, the lamp pole is manually rotated to rotate. The rotation of the lamp pole drives the support plate and the lamp body to rotate. The rotation of the support plate drives the solar panel to rotate to adjust the angle of the solar panel. The adjustable solar panel can adjust the angle so that the solar panel always faces the sun at the best angle, avoids the shadows of buildings or trees, reduces the impact of shading on power generation, and thus improves the efficiency of capturing light energy.

[0016] (2) The angle-adjustable solar street light moves upwards through the squeeze ring squeezed by the protective umbrella. The squeeze ring's upward movement will shake off the debris or snow accumulated on the top of the protective umbrella. The design of the protective umbrella can enhance the stability of the overall structure of the solar street light and reduce the damage to the lamp pole caused by wind. In cold weather conditions, the snow or ice on the protective umbrella will increase the weight and pressure, which will cause damage to the protective umbrella and the lamp body. The shaking will help to clear the snow and ice in time and prevent the damage to the lamp pole structure. At the same time, the vibration of the support rod drives the squeeze ring to vibrate, and the vibration of the squeeze ring drives the protective umbrella to resonate together. The resonance of the protective umbrella can loosen the snow and ice on the top of the protective umbrella and further shake off the debris or snow on the top of the protective umbrella.

[0017] (3) The angle-adjustable solar street light releases the seal of the liquid inlet pipe by deforming the rubber block. After the seal of the liquid inlet pipe is released, the lubricating oil at the bottom of the load-bearing frame enters the hollow lamp frame through the liquid inlet pipe to quantitatively lubricate the rotating part of the hollow lamp frame and the lamp pole. Lubrication reduces the wear between the rotating parts. The friction is reduced by lubrication, making the rotation of the hollow lamp frame and the lamp pole smoother and avoiding jamming, thereby improving the efficiency and accuracy of angle adjustment. In addition, quantitative lubrication can accurately control the amount of lubricant used, ensuring that the lubrication part is uniformly and fully lubricated, avoiding the problem of excessive or insufficient lubricant.

The linkage plate 15 is fixedly mounted on the side of the adjustment rod 11 away from the lamp pole 3. By setting the U-shaped rod 13 to prevent personnel from misadjusting, the solar panel 6 can always be maintained at the optimal angle, ensuring maximum light energy absorption, improving battery charging efficiency and lighting time of the lamp body 4.

[0028] A spring No. 1 is provided between the adjustment frame 10 and the adjustment rod 11 , which can drive the adjustment rod 11 to reset. The adjustment rod 11 contacts the inner wall of the adjustment hole 9 , and the solar panel 6 is electrically connected to the lamp body 4 .

[0029] A second spring is provided between the adjustment frame 10 and the U-shaped rod 13 , which can drive the U-shaped rod 13 to reset. The U-shaped rod 13 contacts the inner wall of the protection hole 12 , and the support block 7 contacts the bottom of the protection umbrella 8 .

The No. 2 spring is squeezed by the U-shaped rod 13 to produce deformation and accumulate force. At the same time, the U-shaped rod 13 moves in the direction away from the adjusting rod 11 to break away from the contact with the protective hole 12 and release the limit on the adjusting rod 11. After the limit of the adjusting rod 11 is released, manually pull the linkage plate 15 to move in the direction away from the lamp pole 3. The linkage plate 15 moves in the direction away from the lamp pole 3 to drive the adjusting rod 11 to move in the direction away from the lamp pole 3. The adjusting rod 11 moves in the direction away from the lamp pole 3 to squeeze the No. 1 spring. The No. 1 spring is squeezed by the adjusting rod 11 to produce deformation and accumulate force. At the same time, the adjusting rod 11 moves away from the lamp pole 3 The adjustment rod 11 is moved in the direction to disengage from the contact with the adjustment hole 9 and release the limit on the lamp pole 3. After the limit of the lamp pole 3 is released, the lamp pole 3 is manually rotated to rotate. The rotation of the lamp pole 3 drives the support plate 5 and the lamp body 4 to rotate. The rotation of the support plate 5 drives the solar panel 6 to rotate to adjust the angle of the solar panel 6. After the angle of the solar panel 6 is adjusted to a suitable position, the linkage plate 15 is released so that the adjustment rod 11 moves in the direction close to the lamp pole 3 under the elastic force of the No. 1 spring. The adjustment rod 11 moves in the direction close to the lamp pole 3 and contacts the inner wall of the adjustment hole 9 and limits the lamp pole 3. At the same time, the adjustment rod 11 moves in the direction close to the lamp pole 3 so that the U-shaped rod 13 moves in the direction close to the adjusting rod 11 under the elastic force of the No. 2 spring. The U-shaped rod 13 moves in the direction close to the adjusting rod 11 and contacts the protective hole 12 and restores the limit protection for the adjusting rod 11.
