Description

Technical Field

[0001] The utility model relates to a probe rack, in particular to an adjustable multi-channel water immersion probe rack. Background Art

[0002] Immersion ultrasonic testing is widely used in the field of ultrasonic flaw detection of pipelines and other components. It uses several ultrasonic probes on a probe rack to detect flaws in pipelines.

[0003] When performing water immersion flaw detection on pipelines, a fixed probe holder with the probe fixed to a probe holder or an adjustable probe holder with adjustable probe angle can be used. Due to the different diameters of pipelines, fixed probe holders are generally used for large-scale flaw detection of a single type of pipeline. In actual applications, operators need to adjust the angle of the probe according to the pipeline diameter to achieve flaw detection of that type of pipeline.

[0004] Chinese patent publication number "CN221007437U" discloses an adjustable liquid immersion probe holder that utilizes several magnetic assemblies on a first curved block and a second curved block to mount the probe. While the probe angle is adjustable, the following issues remain. Specifically, the adjustable liquid immersion probe holder has a complex overall structure, and the connection reliability of the magnetic assemblies is low, making the probes susceptible to displacement or even detachment during use. Furthermore, the magnetic assemblies are connected to slots on the second fixed block via a movable shaft, allowing them to move and rotate. However, their angles are difficult to fix, and due to the weight of the probes, they are prone to movement and rotation during use, making them impractical. Furthermore, the magnetic assemblies are mounted on two curved blocks, the first and second curved blocks. Since the shapes of the first and second curved blocks are fixed, while the probe angles can be adjusted, the fixed diameter of the curved blocks limits their applicability. Furthermore, since the probes are located inside the curved blocks, they can only inspect the exterior of pipelines, not the interior, further reducing their applicability. Therefore, a new probe holder needs to be designed to solve the above problems. Summary of the Invention

[0005] In order to solve the above technical problems, the utility model provides an adjustable multi-channel immersion probe holder which has a simple structure, is easy to adjust the probe and has a wide range of applications.

[0007] The advantage of this adjustable multi-channel immersion probe holder is that it is equipped with an adjustable probe assembly on its frame. The adjustable probe assembly includes two fixed plates fixedly connected to the frame, with a number of probe connectors positioned between the fixed plates. The adjustable probes are fixedly mounted on these connectors. Adjacent probe connectors, as well as probe connectors and adjacent fixed plates, are connected by a damping shaft.

[0008] Furthermore, in the adjustable multi-channel immersion probe rack of the present invention, there are two adjustable probe groups, which are respectively arranged on the left and right sides of the rack.

[0011] The setting of the mounting block realizes the installation and positioning of the fixed probe. The operator can adjust the position and posture of the mounting block according to the predetermined angle of the fixed probe so that the fixed probe can reach the predetermined angle.

[0012] Furthermore, the utility model provides an adjustable multi-channel immersion probe holder, wherein the probe connecting seat includes a probe mounting plate, connecting plates located at the left and right ends of the probe mounting plate and fixed to the probe mounting plate, the surface of the probe mounting plate is provided with a through-hole for mounting an adjustable probe, and the adjustable probe is fixed to the probe mounting plate by a bolt, one end of which passes through the through-hole on the surface of the probe mounting plate.
