Description

Technical Field

[0001] The utility model relates to the field of pipeline anti-corrosion layer detection, in particular to an anti-corrosion layer electric spark detection device. Background Art

[0002] The use of pipelines is extremely common. According to the needs of the conveying medium, some steel pipes need to be treated with internal and external anti-corrosion before being put into use. High-quality anti-corrosion layers are crucial to extending the service life of pipelines and achieving safe operation. Pipeline internal patching is the key and difficulty in the application technology of pipeline anti-corrosion layers. Due to improper internal anti-corrosion patching, the coating at the weld is destroyed prematurely, and pipeline corrosion and perforation accidents will often occur. my country has relatively mature technology and special instruments and equipment for the detection of anti-corrosion layers.

[0003] However, the existing pipeline anti-corrosion layer detection device still has the following problems during specific use: due to the different diameters of pipelines, the existing pipeline anti-corrosion layer detection mechanism cannot adapt to the changes in pipeline diameters and cannot perform detection on different pipeline diameters. The traditional point-and-needle detection device can only detect a single area alone, and the detection volume is too large. Utility Model Content

[0004] In order to solve the technical problems that the existing pipeline anti-corrosion layer detection mechanism cannot adapt to the change of pipeline diameter and cannot detect different pipeline diameters, the traditional point needle type detection device can only detect a single area alone and the detection amount is too large, the utility model provides an anti-corrosion layer electric spark detection device.

[0005] The utility model is implemented by the following technical scheme: an anti-corrosion layer electric spark detection device, characterized in that it includes a detection device body, the detection device body includes a movable sleeve, one end of the movable sleeve is connected to a movable rod, the outer side of the movable rod is provided with a handle, the movable rod passes through the movable sleeve, the top of the movable rod is connected to a pulling rod, the top of the pulling rod is connected to a reset spring column, a connecting seat is installed on the outer side of the top of the pulling rod, and the top of the reset spring column is connected to a movable disk;

[0006] The outer side of the movable disk is movably connected to a movable shaft seat, the outer side of the movable shaft seat is movably connected to a deflection axis, the outer side of the deflection axis is connected to a connecting rod, one end of the connecting rod is connected to the deflection axis, and the other end is connected to the movable axis, the outer side of the movable axis is connected to a detection bracket, one end of the detection bracket is connected to the movable axis, and the other end is connected to the adjustment axis, the adjustment axis is connected to the outer side of the connecting seat, the top end of the detection bracket is connected to a support rod, the top end of the support rod is sleeved with an electric spark detection rod, and the inner side of the electric spark detection rod is clamped with a detection pipe.

[0007] When in use, the staff holds the movable sleeve with his hand and then pulls the handle, which drives the movable rod to be pulled outward synchronously, and the movable rod then drives the pulling rod connected to its top to move synchronously, and the pulling rod then pulls the reset spring column connected to it, and the reset spring column is compressed, and the reset spring column then pulls the movable disk connected to its top, and the movable disk then moves toward the direction of the connecting seat, and the movable shaft seat connected to the outside of the movable disk moves synchronously, and the movable shaft seat drives the deflection axis and the connecting rod to deflect, so that the connecting rod deflects an angle and pulls the movable axis connected to its top to move, and the movable axis then synchronously pulls the connected detection bracket to move, and the detection bracket drives the support rod to shrink synchronously, and the electric spark detection rod connected to the top of the support rod shrinks synchronously, so that the electric spark detection rod contacts the surface of the detection pipe (both longitudinal and transverse detection are possible here, such as Figure 2 as well as Figure 3 status shown).

[0008] As a further improvement of the above solution, three groups of support rods are provided, and three groups of spark detection rods are also provided. The three groups of spark detection rods are connected to the top of the support rods.

[0009] As a further improvement of the above scheme, the spark detection rod is connected to a spark detector with an external wire. The spark detector is an existing product with a product model of British PTES4001. By turning on the spark detector, the staff manually controls the movement of the detection device body, and the spark detection rod moves on the surface of the detection pipeline. When the spark detection rod contacts the part where the anti-corrosion layer of the detection pipeline is missing, sparks will be generated (here is the working principle of the prior art spark detector), so that the missing part of the anti-corrosion layer of the detection pipeline can be determined, and it can adapt to the detection of pipelines of various sizes.

[0010] As a further improvement of the above solution, the movable shaft seat and the connecting rod are connected via a deflection axis, and the deflection axis realizes relative movement between the connecting rod and the movable shaft seat;

[0011] The connecting rod and the detection bracket are connected via a movable axis, and the movable axis realizes relative movement between the connecting rod and the detection bracket.

[0012] As a further improvement of the above solution, the top end of the pull rod is connected to the reset spring column, the bottom end of the pull rod is connected to the movable rod, the pull rod is connected to the inner side of the movable sleeve, and the pull rod moves inside the movable sleeve.

[0013] Compared with the prior art, the beneficial effect of the utility model is that: the utility model works through the point spark detector, the staff manually controls the movement of the detection device body, the spark detection rod moves on the surface of the detection pipeline, and when the spark detection rod contacts the part where the anti-corrosion layer of the detection pipeline is missing, sparks will be generated (here is the working principle of the prior art spark detector), so as to determine the part where the anti-corrosion layer of the detection pipeline is missing, and it can adapt to the detection of pipelines of various sizes.
