Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of probe fixtures, and particularly relates to a protective base for a magnetic probe fixture. Technical Background
[0002] During the process of transporting media, oil and gas pipelines are extremely vulnerable to the impact and corrosion of the media. Therefore, technologies for real-time detection of pipeline walls have emerged. Ultrasonic thickness measurement probes are generally installed at pipeline elbows where the impact and corrosion are the greatest.
[0003] Since magnetic probes are extremely easy to directly adsorb on iron, it is easy to damage the probe in the middle of the magnet. Content of the Utility Model
[0004] In view of the deficiencies in the background technology, the utility model provides a protective base for a magnetic probe fixture, which can protect the probe from directly adsorbing on iron and thus causing damage to the probe.
[0005] To solve the above problems, the utility model provides a protective base for a magnetic probe fixture, including a base. A connecting cylinder is provided on one side of the base. A groove body is provided on the opposite side of the base where the connecting cylinder is located. The groove body is communicated with the inside of the connecting cylinder. An installation groove is further provided on the side of the base where the groove body is located. A protective cylinder is slidably connected in the installation groove. A positioning mechanism for restricting the protective cylinder is provided on the base.
[0006] Through the above scheme, the installation groove is located on the outer circle of the groove body. The protective cylinder protects the probe to prevent the probe from directly colliding with the pipeline.
[0007] Further, a limiting groove is provided in the installation groove. A limiting eaves is provided at one end of the protective cylinder located in the installation groove. The limiting eaves is slidably connected in the limiting groove. A plurality of uniformly arranged first springs are fixedly installed on the upper side of the limiting eaves. The movable ends of the first springs abut against the bottom of the limiting groove.
[0008] Through the above further scheme, the first spring can push against the limiting eaves to prevent the limiting eaves from shaking. The elastic force of the first spring is small, and the suction force of the strong magnet is greater than the elastic force of the first spring.
[0009] Further, a card hole is provided on the base. One end of the card hole is communicated with the limiting groove, and the other end penetrates through the base to the outside. The positioning mechanism is slidably connected in the card hole.
[0010] Through the above further scheme, the protective cylinder is restricted by the positioning mechanism.
[0011] Further, the clamping mechanism includes a clamping rod and a second spring. The clamping rod is slidably connected in the clamping hole. A moving groove is provided in the clamping hole. A limiting ring is provided on the clamping rod. A second spring is provided on the limiting ring. The limiting ring is slidably connected in the moving groove. The movable end of the second spring abuts against the end of the moving groove. A clamping groove is provided at one end of the outer side of the base of the clamping hole. A limiting ear is provided on the clamping rod. The limiting ear is slidably connected in the clamping groove.
[0012] Through the above further solution, the second spring can position the end of the clamping rod in the limiting groove to restrict the protective cylinder. The end of the clamping rod outside the base can be used to stretch the clamping rod, slide the limiting ear out of the clamping groove, and rotate the clamping rod so that the limiting ear is stuck outside the base. Furthermore, the end of the clamping rod located in the limiting groove can be moved outwards to prevent the end of the clamping rod from blocking the movement of the protective cylinder.
[0013] Further, an annular magnet is provided in the groove body. A probe, a gasket, and a spring are sequentially placed in the connecting cylinder from bottom to top. A top cover is connected to the opening of the connecting cylinder.
[0014] Through the above further solution, one end of the spring abuts against the top cover, and the other end abuts against the gasket, so that the gasket is always in contact with one end of the probe. Under the extrusion of the gasket, the other end of the probe passes through the annular magnet and is in close contact with the pipeline.
[0015] Further, one side of the gasket is in contact with one end of the probe. The other end of the probe is located in the annular magnet. The surface of the gasket in contact with the probe is smooth.
[0016] Through the above further solution, the gasket can be in close contact with the probe.
[0017] Further, at least one sliding groove is provided on the inner wall of the connecting cylinder. A convex platform slidably connected to the sliding groove is provided on the side of the gasket. The number of convex platforms is the same as the number of sliding grooves.
[0018] Through the above further solution, the cooperation between the sliding groove and the convex platform can prevent the gasket from rotating and affecting the fit between the gasket and the probe.
[0019] Further, a thread is provided on the outside of the connecting cylinder. A thread is provided in the top cover. The top cover is threadedly connected to the connecting cylinder.
[0020] Through the above further solution, the threaded connection facilitates the disassembly and installation of the top cover.
[0021] Further, a notch penetrating the inside and outside of the connecting cylinder is provided on the connecting cylinder.
[0022] Through the above further solution, the data cable on the probe can be pulled out from the notch.
[0023] The beneficial effects of the present utility model are as follows: The probe is protected by the protective cylinder to prevent the probe from directly colliding with the pipeline. The protective cylinder is restricted by the clamping mechanism, which further enhances the protection intensity of the protective cylinder for the probe. BRIEF DESCRIPTION OF THE DRAWINGS
