Bridge vibration detection device

Abstract

The invention discloses a bridge vibration detection device. The bridge vibration detection device comprises a battery, a vibration transducer, a resistor, a first capacitor, a second capacitor, a first audion, a second audion, a control chip and a voltmeter. Compared with the prior art, the bridge vibration detection device is composed of only a few electronic components, the size of a finished product is small, and the finished product is convenient to carry; when detection is carried out, only the bridge vibration detection device needs to be placed on a bridge to judge the changes of a pointer, and namely, the vibration condition of the bridge can be judged; and the judging and using are convenient, and the bridge vibration detection device has the popularization and application value.

Description

technical field [0001] The invention relates to a bridge safety detection auxiliary device, in particular to a bridge vibration detection device. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, ban...

AI Technical Summary

Problems solved by technology

In the existing technology, the security inspection of bridges generally only checks cracks, etc., but when the bridge is long, the vibration is relatively large, and it is necessary to judge whether the vibration intensity of the bridge is too strong, so as to judge the bearing capacity of the bridge. Strength is not convenient enough, therefore, there is room for improvement
