Technical Field

[0001] The utility model relates to the technical field of counting wheel accessories of a pile foundation sonic wave tester, and more specifically to a wired-to-wireless transmission device suitable for a counting wheel of a pile foundation sonic wave tester. Background Art

[0002] The core of the pile ultrasonic detector is ultrasonic technology. It uses a pair of ultrasonic sensors, one of which is used as a transmitter and the other as a receiver. Ultrasonic waves are high-frequency sound waves, and their frequencies are usually beyond the range that the human ear can hear, generally above 20kHz. The ultrasonic waves generated by the transmitter are transmitted through the pile material. When the ultrasonic waves encounter interfaces, cracks, voids and other unevenness in the pile, part of the energy will be reflected back to the sensor. Based on the characteristics of the reflected signal, the internal structure and state of the pile can be analyzed.

[0003] At present, pile foundation sonic wave testers usually use two types of ultrasonic waves, namely long waves and short waves, and the sonic testing wheel equipped with the pile foundation sonic wave tester is transmitted by wired connection. The wired transmission distance is limited by the wire length. Generally, a wire of about 20 meters is required to meet the use needs under most on-site conditions. However, the configured wire length is too long, and when there are many devices that need wired connection, the storage and installation are very inconvenient. For this reason, we designed a wired-to-wireless transmission device suitable for the counting wheel of the pile foundation sonic wave tester to solve the above problems. Utility Model Content
