Energy-saving advertising board used on expressway side

Abstract

The invention provides an energy-saving advertising board used on an expressway side. A stand column is rotationally connected with an advertising board body, so that the advertising board body can rotate around the stand column by a certain angle under the wind action; an LED advertisement display screen is connected with a solar cell, the solar cell is connected with a solar cell panel, and the solar cell panel is arranged at the top of the advertising board body. Compared with the prior art, the energy-saving advertising board used on the expressway side effectively solves the problem that an outdoor advertising board is easy to damage under the windward wind action. The situation that the advertising board is damaged under constant windward wind action is effectively avoided, the service life of the advertising board can be effectively prolonged, and the maintenance cost is saved; besides, the problem that electricity is unavailable on the expressway is solved, the LED advertising display screen can be sheltered from wind, rain and sunshine, the service life of the advertising board is prolonged, and the situation that the view of people is affected due to perpendicular incidence of sunshine on the display screen is avoided.

Description

technical field [0001] The invention relates to the technical field of high-speed billboards, in particular to an energy-saving billboard suitable for expressways. Background technique [0002] In modern society, advertising has become a part of people's life, and it appears in front of people in various media and ways, and outdoor advertising is one of them. Outdoor advertisements include advertisements installed on buildings and billboards erected on both sides of roads, such as highways.

Due to the high height of the billboard, it is often affected by the frontal wind force. In the case of a typhoon and other large wind force, the billboard bears a large force. The long-term wind effect will inevitably lead to damage and mainte...
