Energy-saving self-cleaning type advertising board for subway tunnels

Abstract

The invention discloses an energy-saving self-cleaning type advertising board for subway tunnels. The energy-saving self-cleaning type advertising board comprises a board body, wherein the side wall of the board body is rotatably connected with a plurality of impellers through a rotating shaft; one of the impellers is made of magnetic materials; a groove is formed in the upper end of the board body; the inner wall of the groove is in sliding connection with a magnetic plate which attracts the corresponding impeller in a sealing manner; the side wall of the magnetic plate is elastically connected with the inner wall of the groove through a telescopic spring; and spiral coils are arranged on the inner wall of the groove in an embedding manner and are in coupled connection with an illumination mechanism which is arranged on the board body. According to the energy-saving self-cleaning type advertising board disclosed by the invention, through rapid rotation of the impellers, the magnetic plate is slid back and forth on the inner wall of the groove, the spiral coils continuously cut magnetic induction lines so as to produce induction current, so and the illumination mechanism which is arranged on the board body gives out light and illuminates the board body, so that information on the board body is conveniently shown; external power supply is not needed, and energy conservation andenvironmental protection are achieved; and meanwhile, illumination is carried out in accordance with coming of vehicles, and therefore, the service life of the illumination mechanism is prolonged, andthe maintenance cost of the advertising board is reduced.

Description

technical field [0001] The invention relates to the technical field of billboards, in particular to an energy-saving self-cleaning subway tunnel billboard. Background technique [0002] Billboards are a tool to display corporate product information or urban culture. At present, billboards can be seen everywhere in public places. For example, billboards are installed on the walls of subway tunnels in subway stations, so that passengers can clearly see them when vehicles pass by. Display information on billboards. [0003] Due to the dark light in the subway tunnel, it needs to be illuminated and displayed all day when the billboard is displayed. Since the vehicles in the subway pass by at intervals, and when no vehicles pass by the billboard, the advertisement The sign is still illuminated and displayed, which wastes a lot of electric energy, and the service life of the lighting mechanism on the billboard is reduced after a long time of lighting, which increases the maintena...

Problems solved by technology

[0003] Due to the dark light in the subway tunnel, it needs to be illuminated and displayed all day when the billboard is displayed. Since the vehicles in the subway pass by at intervals, and when no vehicles pass by the billboard, the advertisement The sign is still illuminated and displayed, which wastes a lot of electric energy, and the service life of the lighting mechanism on the billboard is reduced after a long time of lighting, which increases the maintenance cost of the billboard, and when the vehicle is running, the ground will be The dust is blown up, making the dust adsorb on the billboard, and after the billboard is displayed for a long time, more dust will accumulate on the surface of the billboard, which will affect the normal display of information on the billboard
