A Bridge Continuous Deformation Detection Device and Bridge Deflection Measurement Method

Abstract

This invention discloses a bridge continuous deformation detection device and bridge deflection measurement method. The bridge continuous deformation detection device comprises a level module, distance measuring module, a dip-angle measurement module, a main control board, a mounting bracket, a stepper motor, a coupling and a rotating base. The distance measuring module and the rotating base constitute a rotating mechanism through the rotating axis, and is connected with the stepper motor through the coupling. The base is fixed on the upper surface of the mounting bracket. The dip-angle measuring module is mounted on the shell of the distance measuring module, which can rotate with it simultaneously. The base of the stepper motor, the main control board, and the level module are mounted on the upper surface of the mounting bracket. The main control board provides power supple and communication interface for the stepper motor, dip-angle measuring module and distancing measuring module. The bridge continuous deformation detection device, easy to operate, precise in detection and reliable in results, is suitable for long-term and continuous measurement of bridge deformation, and can further provide a prospect for on-line monitoring of deflection.
