This patent belongs to the technical field of solar street light equipment, and specifically refers to an angle-adjustable solar street light, which effectively solves the problem that when adjusting the lighting angle of solar street lights on the market, workers need to climb to the top to operate, which is risky to work at a high place, and when adjusting the irradiation angle of the solar street light from above, it is impossible to accurately determine whether the best lighting effect is achieved, and two people are required to operate, one to observe and the other to adjust, which wastes manpower and has high safety risks.

[0004] The above patent effectively solves the problem that when adjusting the lighting angle of solar street lights on the market, workers need to climb to the top to operate. Working at heights is risky, and 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.

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 inappropriate 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 a solar street light with adjustable angle, which has the following beneficial effects:

[0015] (1) When the angle of the lamp body or solar panel of the angle-adjustable solar street light needs to be adjusted, the U-shaped rod must be manually pulled to move it out of contact with the protective hole and release the limit on the adjustment rod. The U-shaped rod is set to prevent people from making mistakes, so that the solar panel can always be kept at the best angle, ensuring maximum light energy absorption, improving battery charging efficiency and lighting time of the lamp body. After the limit of the lamp pole is released, the lamp pole is manually rotated to rotate, and 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 on the protective umbrella, and the squeeze ring moves upwards to 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, causing damage to the protective umbrella and the lamp body. The shaking can help to remove the snow and ice in time to prevent 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 perform quantitative lubrication on the rotating part of the hollow lamp frame and the lamp pole. Lubrication reduces the wear between the rotating parts. Lubrication reduces friction, 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. Quantitative lubrication can also accurately control the amount of lubricant used, ensuring that the lubrication point obtains consistent and sufficient lubrication, avoiding the problem of excessive or insufficient lubricant.
