Description

Technical Field

[0001] The utility model relates to the field of ultrasonic detection, in particular to a concave-convex surface ultrasonic reflection detection device based on an underground continuous wall. Background Art

[0002] The operating principle of an ultrasonic sensor is based on the characteristics of ultrasound, such as high frequency, short wavelength, minimal diffraction, and good directionality. In the sensor, the ultrasonic transmitter converts electrical energy into mechanical oscillations, generating ultrasonic waves. When the ultrasonic waves encounter the object or medium being measured, they are reflected or refracted, and then the receiver receives the echo. The receiver then converts the mechanical vibrations of the echo into an electrical signal, which is processed and output by electronic equipment. Based on the relationship between propagation time and distance, the distance between the object or medium being measured and the sensor can be calculated by measuring the round-trip time of the ultrasonic wave. This method is commonly known as the time difference method or transit time method. Furthermore, additional information can be obtained by measuring parameters such as the amplitude and phase of the ultrasonic wave.

[0003] However, the ultrasonic reflection detection device currently in use is an integral structure. When in use, due to the external temperature or the position difference between the transmitter and the receiver, there are some errors in the detection device during measurement that cannot be eliminated, making it extremely inconvenient to use.

[0004] Simple improvement method: In view of this, the existing problems are studied and improved, and an ultrasonic reflection detection device for concave and convex surfaces based on underground continuous walls is provided. It has a reasonable structural design and reduces the error of the results caused by temperature difference through the circulation of coolant. At the same time, the transmitter and receiver are reset in the motor and cylinder to reduce the errors caused by detection blind spots and different positions. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content
