A detection system based on ultrasonic transducer

Abstract

The invention relates to a detection system based on ultrasonic energy conversion, which includes a channel, a track, a base, an ultrasonic generator, an ultrasonic receiver, a displacement sensor, an acoustic wave analysis device, and a data display screen. The analysis device is equipped with a second wireless transceiver and a central control module. The central control module is used to analyze the sound waves. The detection system is used to detect the initial stage. The base is located at the beginning of the channel. The central control module controls the ultrasonic generator to emit ultrasonic waves. The receiver receives the reflected ultrasonic signal and transmits the received signal to the acoustic wave analysis device through the first wireless transceiver, and the base moves along the track at a constant speed while the ultrasonic generator emits ultrasonic waves. The invention receives the reflected ultrasonic signal in real time through the ultrasonic receiver, and the central control module determines whether the grouting bellows grouting is qualified by analyzing the sound wave intensity, thereby ensuring the quality of the project and providing powerful data support for bridge repair and maintenance.

Description

Technical field [0001] The present invention relates to the field of ultrasound detection, and more particularly to a detection system based on ultrasound energy. Background technique [0002] With the development of bridge technology, there is an increasing bridge construction in engineering technology, and the prestressed bridge steel strand is a key carrying structure of such bridges. The grouting density of the bellows is related to steel. The linear load capacity is played, and the evaluation of bridge corrugation grouting defects is important. There are two main aspects: one is to protect the prestressed ribs; the second is to ensure that the prestressed ribs are working together and control the spacing and width of cracks during overload, while avoiding the stress of the prestressed ribs Overcast. [0003] At present, the quality problems that often appear in the prestressed bellows grouting construction process are: 1, grout is not true; 2, the bellows are not fully full ...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the present invention provides a detection system based on ultrasonic energy conversion, which is used to overcome the problem in the prior art that the signal value loss is large during the quality detection of the grouting bellows, resulting in less repair and maintenance data of the bridge.
