Description
Technical Field
[0001] The utility model relates to the technical field of detection devices, in particular to a bridge deck crack detection device. Background Art
[0002] Ultrasonic detection of bridge deck cracks is a non-destructive detection method that uses ultrasound as a medium to obtain internal information of an object. In bridge deck crack detection, the ultrasonic method is mainly used to determine the crack depth. The transmitting probe and the receiving probe are arranged near the crack on the same surface of the concrete. Information inside the crack is obtained through the propagation and reflection of ultrasound. When ultrasound propagates in concrete, it will produce reflection and refraction when it encounters cracks. By analyzing these reflected and refracted waves, the depth, direction and other parameters of the crack can be inferred. By comparing parameters such as the ultrasonic signal strength and propagation time at different locations, the specific location and depth of the crack can be determined.
[0003] However, in actual operation, since there is usually a lot of dust on the bridge surface, dust as a medium may change the propagation characteristics of ultrasound and lead to inaccurate detection results. Specifically, dust may absorb part of the ultrasonic energy and reduce the signal strength, thereby making the detected signal blurred or difficult to identify. In addition, dust may also produce a scattering effect, causing the ultrasonic wave to deflect or diffuse during the propagation process, further affecting the accuracy of the detection results, and thus affecting the ultrasonic detection structure. The manual method of cleaning the dust in advance is labor-intensive and requires special cleaning work, which is time-consuming and labor-intensive, and is not conducive to practical applications.
