A self-cleaning device for led street lamps

Abstract

The invention discloses a self-cleaning device for LED street lamps, which comprises a lamp post and a lamp holder fixedly installed on the top of the lamp holder through a connecting frame. There is a first ring gear, and the lampshade is fixedly connected to the lower end of the first ring gear. In the present invention, by arranging a wiping mechanism, a deceleration belt, a sealing plate, a sliding plug, a gear and a first ring gear, when a car passes the road next to the street lamp, the deceleration belt and the sealing plate can be pressed down, thereby pumping the air into the device cavity. Air, push the sliding plug to move up, thereby driving the threaded rod to rotate, so that the gear meshes with the first ring gear to rotate, the first ring gear drives the lampshade to rotate, and the arc-shaped scraper scrapes off the dust on the surface of the lampshade to keep the surface of the lampshade clean. And when the sliding plug moves up, the air in the device cavity will be squeezed into the water collection cavity, thereby squeezing the water into the cavity, and the arc-shaped scraping strip absorbs the water, so that the cleaning effect is better when wiping the lampshade.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a self-cleaning device for LED street lamps. Background technique [0002] Road lighting is closely related to people's production and life. With the acceleration of urbanization in our country, LED street lights have gradually entered people's field of vision because of their directional light emission, low power consumption, good driving characteristics, fast response, high shock resistance, and long service life. Long, green and environmental protection and other advantages, LED street lights will become the best choice for road lighting energy-saving renovation. [0003] However, because LED street lights have been in the road environment for a long time, the traffic on the road constantly raises dust on the road, so there is a lot of dust in the environment, and LED street lights are usually composed of light poles, lamp holders and lampshades. After a period of use, the air wi...

Problems solved by technology

[0003] However, because LED street lights have been in the road environment for a long time, the traffic on the road constantly raises dust on the road, so there is a lot of dust in the environment, and LED street lights are usually composed of light poles, lamp holders and lampshades. After a period of use, the air will The dust floating in the air will adhere to the surface of the transparent cover at the lower end of the lampshade. As the dust continues to accumulate, the lighting performance of the LED street lamp will become worse and worse. It is necessary to wipe and clean the surface of the transparent cover to improve its lighting performance. Since street lamps are usually relatively high, it is obviously unreasonable to use manual climbing and wiping to clean them. Therefore, it is necessary to design a self-cleaning device that can automatically wipe and clean the transparent cover of LED street lamps.
