Bridge wind barrier device with adjustable height and porosity

Abstract

The invention discloses a bridge wind barrier device with adjustable height and porosity. The bridge wind barrier device comprises a rack, a wind shielding belt, an anemorumbometer, a weighing module,a high-definition snapshot module and a data processing and control module. A roller rotationally connected with the rack is arranged on the rack. The roller used for supporting the wind shielding belt, lifting devices are arranged on the two sides of the rack. The lifting device is used for achieving lifting of the roller, the wind shielding belt winding and unwinding devices are arranged on thetwo sides of the rack, through holes of different sizes are formed in the wind shielding belt, the size of the through holes of the wind shielding belt can be changed, and bidirectional adjustment ofthe size and the height of the through holes of the wind shielding belt can be achieved to adapt to different weathers. And the data processing and control module can receive data such as wind speedand load, send an instruction to the wind barrier module in combination with information of the weighing module, and adjust related parameters of the wind barrier module.

Description

technical field [0001] The invention relates to the technical field of bridge windshields, in particular to a bridge windshield device with adjustable height and porosity. Background technique [0002] In recent years, high-speed cross winds on the bridge deck have caused sideways accidents on the bridge deck, which have seriously affected the safety of vehicles driving on the bridge. At present, the traffic management department mainly adopts management measures such as limiting the speed of vehicles and closing traffic to reduce the cross wind For the impact on vehicles driving on the bridge deck, the two measures are mainly determined by subjective judgment and experience, lacking scientific theoretical basis and data support. Blindly formulating speed limit standards and shutting down traffic measures will not only threaten vehicle safety and bridge traffic efficiency, but also cause huge economic losses and negative social impacts. [0003] In order to ensure the safet...

Problems solved by technology

At present, in actual engineering applications, barricade-type windshields are mainly used, and board-dug hole-type windshields are rarely used. Therefore, it is of great significance to strengthen the application of board-dug round-hole windshields; Compared with the form of porosity, on the one hand, it cannot provide enough windshield effect for bridge deck driving in windy weather, which affects the safety of bridge deck vehicles; on the other hand, in light windy weather, it affects the sight of drivers and affects the urban landscape
