Solar street lamp

Abstract

The invention belongs to the technical field of solar illumination, and particularly discloses a solar street lamp. The solar street lamp comprises a lamp holder and a street lamp pole arranged on thelamp holder, wherein a lamp and a solar cell panel are arranged on the street lamp pole; ring buckles are arranged at the top end of the street lamp pole; the central axes of the ring buckles are perpendicular to the central axis of the street lamp pole; a transverse rotating shaft is rotatably connected in the ring buckles; each end of the rotating shaft is connected with one gear; a rotating rod is fixedly connected to the middle part of the rotating shaft in the vertical direction; the rotating rod is fixedly connected with the solar cell panel; transparent glass chambers are mounted on the two sides of the lower surface of the solar cell panel; air sacs are placed in the glass chambers; the glass chambers are provided with opening channels; openings of the two opening channels face the street lamp pole; the opening channels are connected with racks in a sliding manner; one ends of the racks are connected with the air sacs; the other ends of the racks are free ends; and the free ends of the racks mesh with the gears. Compared with the prior art, the solar street lamp has the advantage that the purpose that the solar cell panel rotates along with sunlight without manpower consumption through a physical process is achieved.

Description

technical field [0001] The invention belongs to the technical field of solar lighting, and specifically discloses a solar street lamp. Background technique [0002] In recent years, solar energy, as a clean, non-polluting renewable energy, has received more and more attention, and its applications have also increased. Among them, solar energy has also been widely used in street lamps, creating a solar energy street light. [0003] Most of the solar panels of existing solar street lamps are fixed on the street light poles with a certain angle towards the south direction, and the solar panels cannot rotate with the sunlight. Because the sun's trajectory changes during the day, the front of the solar panels is not always It is perpendicular to the sun's rays, making the utilization efficiency of solar energy low. Therefore, there is a need for a street lamp whose solar panel can rotate with the sun, so as to increase the utilization efficiency of solar energy. Contents of t...
