Device for automatically protecting billboard by utilizing natural wind power

Abstract

The invention relates to the technical field of billboards, and discloses a device for automatically protecting a billboard by utilizing natural wind power, a combining piece is movably connected to the left side in a metal fitting, and an extension rod is movably connected to the bottom end of a flat plate. According to the device for automatically protecting a billboard by utilizing natural windpower, when wind blows outdoors and the wind speed is larger than the weight of a turntable, the device runs when the wind speed is larger than the wind power action of the turntable, the turntable acts on a linkage rod to rotate which is an intermittent motion and rotates by 120 degrees each time, the user has enough remaining time, under the matching action of a rotating shaft, a bevel gear anda vertical rod, and when the device rotates, the effect of three-side sequential rotation is formed, so that the advertising component has the effect of three-side rotation display, the device can check information on the advertising component more visually and more clearly through all-dimensional rotation, and the purposes of all-dimensional propaganda, energy saving and cost reduction are achieved.
