Wind-driven propaganda device for garden green belt

Abstract

The invention relates to the technical field of green belt propaganda devices, in particular to a wind-driven propaganda device for a garden green belt. The device comprises a supporting mechanism, a lifting mechanism, a driving mechanism, a propaganda mechanism, a beating mechanism and a warning mechanism; the top of the supporting mechanism is slidably connected with the lifting mechanism, the lifting mechanism can adjust the length of the whole structure according to the height of plants on the green belt, propaganda is prevented from being shielded, and operation is easy; the top of the lifting mechanism is fixedly connected with a driving mechanism, the driving mechanism is meshed with the propaganda mechanism, when the driving mechanism is driven by wind power, the driving mechanism rotates the propaganda mechanism for fixing the slogans, pedestrians can conveniently observe the propaganda slogans on the two sides, and unnecessary troubles caused by the fact that information is not seen are avoided; and a beating drum is mounted at one end of the driving mechanism, and the beating mechanism is driven to rotate when the driving mechanism is driven to rotate by wind power, so that the warning mechanism is driven to shake when the beating mechanism rotates, and pedestrians are reminded to observe propaganda words.

Description

technical field [0001] The invention relates to the technical field of green belt publicity devices, in particular to a wind-driven publicity device for landscaping green belts. Background technique [0002] Separation of traffic by the green belt, with safety features. The green belt can beautify the city and eliminate the driver's visual fatigue. The planting of the arbor green belt can also change the spatial scale of the road, so that the road space has a good aspect ratio. In addition, it also has the effect of purifying the environment, can hold dust, reduce noise, absorb harmful gases, and release oxygen; the width of the green belt should be appropriate for the width of the road. There are buildings on both sides of the road, and the width of the green belt should not exceed 3 meters. 4 meters above the sidewalk. It is also possible to design a sidewalk with a width of more than 4 meters and plant a row of street trees to achieve basic greening and shade. There are...

Problems solved by technology

[0003] The current publicity devices on the landscaping belts are directly inserted into the soil. If there are slogans or advertisements on both sides of the fixed plate that fixes the propaganda slogan, the fixed plate is difficult to rotate, which makes it difficult for pedestrians to observe the two sides on the side of the road. Advertisements in different directions lead to insufficient information publicity, and as time goes by, the height of the green plants on the green belt becomes higher, and it is difficult to adjust the fixed pole of the advertising slogan, and the green plants will cover the propaganda slogan, making the propaganda device unusable; Even the moving slogans failed to make a sound to remind pedestrians, and it was difficult for pedestrians to observe the slogans
