Advertising board capable of automatically ascending and descending based on wind power

Abstract

The invention provides an advertising board capable of automatically ascending and descending based on wind power, and relates to the technical field of advertising media. According to the advertising board capable of automatically ascending and descending based on the wind power, the top of a base is elastically connected with a machine body shell, the top of the machine body shell is rotationally connected with fan blades, the interior of the machine body shell is rotationally connected with an extrusion mechanism, and the interior of the machine body shell is fixedly connected with a stretching mechanism. According to the invention, fan blades are driven to rotate through wind power, and a screw rod and a gear are used in cooperation, so that the larger wind power is, the longer spring rod extends under action of centrifugal force;by matching an extrusion cover and a stress plate, a first magnetic pole is made to be close to a second magnetic pole, so that the center of a machine body shell is lowered so as to achieve the automatic lifting effect; and through cooperative use of a push rod and a threaded rod, a threaded ring rotates to drive a telescopic rod to extrude a cleaning roller, so that the cleaning roller on the surface of the machine body shell is driven to slide, and the effect of cleaning dust is achieved.

Description

technical field [0001] The invention relates to the technical field of advertising media, in particular to a billboard that can be automatically raised and lowered based on the wind force. Background technique [0002] Advertising media is the communication carrier used to release advertisements to the public. It refers to the material and technical means used to disseminate product or service information. The four traditional advertising media are TV, radio, newspapers and magazines. In the advertising industry, TV media and Radio media is called radio media, and newspapers and magazines are called print media to distinguish them, while billboards are a derivative of print media, which mainly disseminate information through outdoors, but traditional billboards in In the case of strong wind, it will tilt or even fall down, so that normal information dissemination cannot be carried out, and in the outdoor environment for a long time, a lot of dust will fall into the inside of...
