Light blocking prevention type solar lawn lamp

Abstract

The invention discloses a light blocking prevention type solar lawn lamp. The solar lawn lamp comprises a supporting column, wherein a light facing plate is arranged at the upper end of the supportingcolumn, a solar cell panel is installed at the upper end of the light facing plate, a ventilation groove is formed in the side wall of the light facing plate, a wind wheel is rotatably connected to the inner bottom of the ventilation groove, a scraping plate is slidably connected to the upper end of the light facing plate, the scraping plate is elastically connected to the side wall of a wind wheel rotating shaft through a spring, pull-back plates are fixedly connected to the two opposite side walls of the scraping plate correspondingly, and an annular groove is formed in the upper end of thelight facing plate. By arranging the wind wheel, the spring, the scraping plate and other components, the wind wheel can be pushed to rotate when wind blows, the scraping plate is pushed to the surface of the solar cell panel through centrifugal force, and therefore, grass leaves and other sundries falling on the surface of the solar cell panel are scraped together; and when the wind stops, the spring pulls the scraping plate to move back, the pull-back plates can push grass leaves and other sundries into the annular groove, and therefore, the grass leaves and other sundries can be effectively prevented from shielding the solar cell panel.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a light-blocking solar lawn lamp. Background technique [0002] In order to improve the landscape effect of the park or community, an appropriate amount of lawn lights are often set on the lawn to bring out the landscape of the lawn. At present, solar lawn lights are more commonly used, which use solar panels to absorb light energy during the day and convert it into electrical energy for storage, and make lawn lights glow at night. [0003] Since lawn lights are often not very high and are set in the open outdoors, when the wind blows, grass leaves or other debris on the ground will inevitably be blown to the solar panels above the lamps and block the solar panels. , greatly reducing the absorption efficiency of solar panels to light energy, and the staff cannot clean the lamps in a long-term and timely manner. Accordingly, this application document proposes a light-blocking sola...
