Smart street lights are an important source of information collection for the Internet of Things, and they are an important component and entrance to smart cities. Ordinary street lights can be classified into high pole street lights, garden street lights, lawn street lights, etc. according to their functions, while smart street lights can integrate smart functions for the street lights under the above categories, such as smart garden street lights, so that smart street lights can be spread all over the city.
[0003] The Chinese patent announcement number is CN214948749U, and the announcement date is November 30, 2021. The name of the invention is a smart street lamp for garden landscaping. The application discloses that the street lamp includes a base, a circular lampshade 301 is arranged on the base, a light-emitting lamp tube is arranged inside the circular lampshade 301, and a ceiling is arranged on the top of the circular lampshade 301, and a solar panel is fixedly installed on the top of the ceiling.
[0004] In the above-mentioned related technologies, solar panels are fixedly connected to the top of the roof and can be used to collect sunlight to power street lamps. However, the angle of sunlight absorption by fixed solar photovoltaic panels remains unchanged. In fact, the position of the sun is constantly changing in different seasons and even at different times of the day. Fixed solar photovoltaic panels are not effective in absorbing sunlight, which may affect the effect of converting solar energy into electrical energy. Utility Model Content
[0005] In order to improve the problem that fixed solar photovoltaic panels are not effective in absorbing sunlight, the present application provides a city street lamp.
[0006] This application provides a city street lamp, which adopts the following technical solution:
[0007] A city street lamp comprises a rod body, wherein the rod body comprises a base, a lighting mechanism arranged on the base, a ceiling arranged on the lighting mechanism and a solar panel arranged on the ceiling in sequence along the length direction thereof, and further comprises an adjustment mechanism for adjusting the angle of the solar panel, wherein the adjustment mechanism comprises a support rod and an adjustment rod respectively hinged to the back of the solar panel, wherein the hinge axes of the support rod and the adjustment rod are parallel to each other, and the end of the support rod away from the solar panel is fixed to the top of the ceiling; the adjustment mechanism further comprises a connecting piece arranged on the ceiling and a driving part for moving the connecting piece back and forth, wherein the moving direction of the connecting piece is not parallel to the plane where the solar panel is located, and the end of the adjustment rod away from the solar panel is hinged to the connecting piece.
[0008] By adopting the above technical solution, when the driving part drives the connecting part to move back and forth, it can drive the adjusting rod to rotate, thereby driving the solar panel to rotate in a circle with the hinge point of the supporting rod as the main body, thereby realizing the angle adjustment of the solar panel; so that the solar panel can adjust the angle of the solar panel according to seasonal requirements and the position of the sun at different times of the day, so that the solar panel faces the sun to absorb more solar energy and then convert it into electrical energy, thereby improving the problem of fixed solar panels absorbing sunlight poorly.

[0014] By adopting the above technical solution, when the motor rotates, it can drive the outer rod to rotate, thereby driving the inner rod to have a tendency to rotate. At the same time, the inner rod is limited by the fixed plate. Under the dual action, the inner rod is driven to move back and forth along the center line of the length direction of the rod body, thereby driving the connecting rod to move back and forth along the center line of the length direction of the rod body, thereby realizing the adjustment of the connecting part by the driving part.
