Energy-saving subway tunnel advertising board

Abstract

The invention discloses an energy-saving subway tunnel advertising board. The energy-saving subway tunnel advertising board comprises an advertising board, wherein a front side wall of the top of theadvertising board is rotationally connected with a plurality of rotating rods, a plurality of fan blades are fixed at a front end of the rotating rod, a mounting cavity is formed in the top of the advertising board, a rear end of the rotating rod extends into the mounting cavity and is fixedly provided with a plurality of connecting cylinders, a tail end of the connecting cylinder is rotatably connected with a connecting rod through a torsion spring, an impact ball is fixed to a tail end of the connecting rod, a tuning fork is fixed to an inner wall of the rear side of the mounting cavity, a fixing plate is fixed to an inner wall of the front side of the mounting cavity, and an elastic piece is fixed to a tail end of an outer side column loudspeaker of the tuning fork. The energy-saving subway tunnel advertising board is advantaged in that evaporation liquid is rapidly heated through friction heat generation, a folding air bag is inflated through evaporation of the evaporation liquid,so evaporation gas is gradually cooled and the folding air bag is reset in the processes of contact between a conductive block and a conductive sheet in the circuit conduction, subway stopping and driving-out process, the lighting time of the advertising board can be controlled, timely power failure of the advertising board is guaranteed, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of subway tunnel billboards, in particular to an energy-saving subway tunnel billboard. Background technique [0002] Billboards are a tool for publicity, and most of them are publicized by placing advertising cloth inside. At present, billboards can be seen everywhere in public places, such as in subway stations, and on the walls of subway tunnels, billboards are installed. [0003] However, the current billboards in subway stations are often connected to the mains and are always on, consuming a lot of power for 24 hours. After the subway enters the station, it will not stay for too long, often only one minute Left and right, and the interval between entering the next subway is relatively long, and the constant lighting of the billboard during this process will cause unnecessary energy consumption. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in th...
