Description

Technical Field

[0001] This utility model relates to the field of sonar detection equipment, and in particular to a pipeline sonar detection probe correction and positioning device. Background Technology

[0002] As a core tool for trenchless endoscopic diagnostics, pipeline sonar inspection technology plays a crucial role in assessing pipeline structural integrity, identifying potential leaks, and preventing geological disasters. Especially in high-risk scenarios such as sewage networks, gas transmission, and integrated utility tunnels, the accurate positioning of sonar probes directly impacts the reliability of the inspection data.

[0003] However, the current mainstream pipeline sonar inspection operation mode relies entirely on operators holding the sonar probe rod deep into the pipeline. Holding the sonar rod for a long time can easily lead to hand fatigue, causing hand tremors and shaking, which can cause the sonar rod to shake and deviate. This can easily cause the sonar beam angle to deviate, making the scanning trajectory form an angle with the real axis, resulting in annular cross-sectional imaging distortion.

[0004] Therefore, in order to solve the problem of easy shaking of handheld sonar rods, a pipeline sonar detection probe correction and positioning device is proposed. Utility Model Content

[0040] It should be noted that the springback section includes: sleeve 6, pressure ring 501 and compression spring 502;

[0041] Specifically, the sleeve 6 is sleeved on the outside of the pressing bolt 5 and located on the side of the insert rod 4. The inner wall of the sleeve 6 is provided with a threaded hole 601 for the pressing bolt 5 to pass through.

By pushing the sonar probe rod 7 to move, the staff can detect the inner wall of the pipeline, avoiding fatigue caused by holding the sonar probe rod 7 for a long time, which would cause the sonar probe rod 7 to shake or deviate.

[0049] In actual use, a locking half-ring 1 is fixed at the end of the pipe. Multiple insert rods 4 on the front of the locking half-ring 1 are connected to the side of the clamping bolts 5. The spring-loaded part limits the rotation of the clamping bolts 5. The movable part at the end of the clamping bolts 5 is used to position the sonar probe rod 7. This avoids the problem of the sonar probe rod 7 shaking and deviating due to fatigue of holding it for a long time when the operator holds the sonar probe rod 7 by hand to inspect the pipeline.
