| titleOfInvention | Ultrasonic transducer for concrete structure detection/monitoring |
| abstract | The invention discloses an ultrasonic transducer for concrete structure detection/monitoring, which comprises a piezoelectric element and a packaging layer, wherein the piezoelectric element is in a circular tube shape; the internal and external surfaces of the piezoelectric element are respectively provided with an electrode, the internal surface is provided with the positive electrode, and the external surface is provided with the negative electrode; the positive and negative electrodes are respectively welded with a wire; the external surface and internal surface of the piezoelectric element are respectively coated with the packaging layer; the top end and bottom end of the piezoelectric element are also respectively coated with the packaging layer; the packaged piezoelectric element has a hollow structure inside; and the packaging layer is a cement-polymer mixture. The transducer is simple to prepare and convenient for distribution, has the characteristics of simple structure, high power capacity, large acoustic radiation area, high radiation efficiency, low frequency, uniform radial radiation, high sensitivity and the like, is very suitable for detecting/monitoring some large-size concrete structures, some foundation piles and the like, and has wide application prospects in concrete detection/monitoring. |
