Fully automatic intelligent control bridge wind barrier

Abstract

The invention is a fully automatic and intelligently controlled bridge wind barrier, comprising a plurality of automatically controlled wind barrier units arranged in a straight line along the direction of the bridge on both sides of the bridge. Each wind barrier unit includes a wind barrier structure system, a transmission system and a control system. The wind barrier structure system includes a plurality of wind barrier bars that can rotate around the rotation axis. The transmission system of the wind barrier includes a transmission gear, a transmission chain, a transmission main shaft and a transmission motor; the transmission motor drives the bars of the wind barrier to rotate around the rotation axis. The wind barrier control system has a wind speed sensor and a central microprocessor; the wind speed sensor is installed on the outside of the bridge wind barrier, and the real-time wind speed and direction data of the bridge monitored by the wind speed sensor are transmitted to the central microprocessor, and the central microprocessor issues instructions to make the wind barrier The bar is rotated to the specified angle to automatically adjust the ventilation rate of the wind barrier. The invention can not only ensure the safety of driving in sidewind of the bridge, but also improve the wind resistance performance of the bridge structure, and can meet the requirements of passengers' driving vision to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a fully automatic and intelligently controlled bridge wind barrier for bridges that can fully automatically and intelligently adjust the rotation angle of wind barrier bars and improve the operational safety of bridge deck vehicles. Background technique [0002] With the development of the economy, bridge spans are getting bigger and bigger, and there are more and more cross-sea and island-connecting projects. However, the characteristics of long lines of cross-sea bridges, high wind speeds on the bridge deck, and heavy traffic tasks make driving safety problems caused by wind more prominent. , the special natural wind environment where cross-sea bridges often have extremely adverse effects on the driving safety of super-long-span bridges. If the wind environment at the bridge site is bad, it will inevitably affect the driving safety of the bridge, thereby affecting the economic ...

Problems solved by technology

[0004] The current wind barriers ensure the wind-shielding effect of the wind barrier by reducing the ventilation rate and increasing the height of the wind barrier. According to the working principle of the wind barrier, it can be known that the wind barrier has a higher wind-shielding efficiency when the ventilation rate is small, but Its aerodynamic resistance to the bridge will increase, which in turn affects the wind resistance safety of the bridge structure; at the same time, due to the low ventilation rate, the driving vision on the bridge deck will also be reduced accordingly, especially for cross-sea bridges, passengers cannot appreciate it when the weather is clear On the contrary, when the ventilation rate of the wind barrier is high, although the view is wide, the corresponding wind reduction effect cannot be achieved, which will affect driving safety

[0005] In order to realize the three-in-one function of bridge structure wind resistance safety, vehicle driving safety, and passenger vision effect, traditional wind barriers are difficult to meet the requirements. Therefore, research on a new type of fully automatic and intelligently controlled bridge wind barrier has become an urgent technical problem to be solved.
