A vortex vibration converter protection device based on wind field monitoring

Abstract

The invention relates to a vortex vibration converter protection device based on wind field monitoring, which includes several typhoon field monitoring devices installed on the inside of the bridge, several windproof deformation baffles installed on the outside of the bridge, the wind field monitoring device and the windproof deformation baffle All are connected to the computer data terminal of the administrator, and the wind field monitoring device is connected to the cloud database; the wind field monitoring device includes an anemometer, a wind direction detector, a horizontal measurement sensor, a first signal transmission device and a first support frame; The windproof deformation baffle includes telescopic deformation steel plate A, telescopic deformation steel plate B, intelligent rotating shaft, second signal transmission device and second support frame; through the present invention, a large number of casualties caused by vortex vibration can be effectively avoided, and at the same time, the vortex The analysis and study of vibration provides a lot of useful data.

Description

technical field [0001] The invention relates to a vortex vibration converter protection device based on wind field monitoring, and belongs to the technical field of natural disaster emergency management. Background technique [0002] On May 5, 2020, the Humen Bridge experienced obvious vertical bending vibration. According to expert analysis, vortex vibration occurred. Although this incident did not cause a major impact on the structural safety of the Humen Bridge, and there were no casualties, but Referring to the incident of the collapse of the Tacoma Bridge due to vortex vibrations, and experts have yet to find out the specific reasons for the vortex vibration phenomenon, this shows that the vortex vibration phenomenon is still a natural disaster with great hidden dangers, and there is no accurate prediction of the vortex vibration phenomenon. In the face of vortex vibration that does not know when it will occur, we need a bridge protection device that can adjust and prev...
