Smart city sign capable of reducing wind resistance based on Bernoulli principle

Abstract

The invention relates to the technical field of signs and discloses a Bernoulli principle-based smart city sign capable of reducing wind resistance. The Bernoulli principle-based smart city sign comprises a sign body, wherein support frames are fixedly connected to upper and lower sides of the sign body, cambered plates are hinged to inner side walls of the support frames, and fixing rods are fixedly connected to the bottoms of the cambered plates; a connecting rod is slidably connected to an outer side wall of the fixing rod, and a compression rod is hinged to one end of the connecting rod; pressure intensity of the upper side of the arc-shaped plate is larger than that of the lower side of the arc-shaped plate, the arc-shaped plate inclines towards the windward side, at the moment, the arc-shaped plate upwards guides and shunts a part of wind, according to a wind resistance formula, wind resistance is in direct proportion to the stress area of an object, at the moment, due to the fact that the arc-shaped plate guides out a part of wind, the stress area of the object is reduced, and a purpose of reducing the wind resistance is achieved; and meanwhile, due to the fact that the cambered surface plate has a certain radian, according to the air wall attachment effect, the cambered surface plate can further guide wind, and a purpose of further reducing wind resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of signage, in particular to a signboard for smart cities that reduces wind resistance based on the Bernoulli principle. Background technique [0002] At present, with the development of smart cities, more and more urban construction needs to be applied to smart cities. Among them, signs are an indispensable tool in urban construction. Based on the design concept of smart cities, the current urban traffic foundation Facilities construction put forward higher requirements. Direction signs are infrastructures built on urban roads, scenic spots, schools, hospitals and other places to guide people or provide other signs. [0003] For taller or larger signboards, their wind resistance capability requires certain requirements. In the prior art, the signboards do not have the function of intelligently adjusting the wind resistance. Larger wind resistance will cause the signboard to fall, which will cause danger. ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a signboard for smart cities based on the Bernoulli principle to reduce wind resistance, which can automatically adjust the angle of the arc panel by using the Bernoulli principle, drain the wind force, and reduce the wind resistance caused by the signboard. The wind resistance is improved, the wind resistance performance of the sign is improved and the surface of the sign is automatically cleaned, which solves the problem that the sign does not have the function of intelligently adjusting the wind resistance. When the sign is subject to strong wind, the sign is easy to Due to the large wind resistance, the signboard will fall, which will cause danger. At the same time, for the higher signboard, it will be more troublesome when cleaning.
