A large-screen billboard for a high-rise building

Abstract

The invention provides a large-screen billboard for a high-rise building. The surface of the base is fixedly connected with a support plate, and the surface of the support plate is fixedly connected with an advertisement frame through electric welding. The inner ring plate is welded, the surface of the support plate is welded with a connecting rod, the surface of the connecting rod is fixedly connected with the outer ring plate, and an annular slideway is arranged between the inner ring plate and the outer ring plate, and the inner wall of the outer ring plate and the inner ring plate Wheel grooves are provided on the surface of the utility model, which relates to the field of billboards. The billboard completely relies on wind power to generate static electricity, and the dust accumulation and removal near the billboard can be reduced under the action of static electricity. Convenience, manual cleaning has great potential safety hazards and high cost, and mechanical cleaning not only consumes a lot of energy, but also cannot be cleaned immediately.

Description

technical field [0001] The invention relates to the technical field of billboards, in particular to a large-screen billboard for high-rise buildings.
