Description

Technical Field

[0001] This utility model relates to the field of pipeline corrosion detection technology, and in particular to a pipeline corrosion protection layer condition detection device. Background Technology

[0002] In the field of transporting energy gases such as oil and natural gas, pipelines are widely used. Before being put into use, these pipelines undergo internal and external anti-corrosion treatment to extend their service life. After a certain period of use, the anti-corrosion layer on the outer wall of the pipeline is prone to damage and needs to be dealt with in a timely manner to ensure the continuous and safe transport of gases. Currently, for underground metal pipelines, a current or voltage signal can be applied to a certain point on the pipeline, and the receiver can be moved on the ground to test the damage point. For the anti-corrosion layer condition detection of above-ground pipelines, the main method is to set up a ring-shaped pipeline inspection device on the pipeline. The device is manually moved along the pipeline axis segment by segment to detect the anti-corrosion layer. However, since there is a certain distance between the above-ground pipeline and the ground, the efficiency of manually moving the inspection device segment by segment is low, and it is impossible to ensure that the relative position of the inspection device and the pipeline remains stable. This is not only inconvenient to operate but also results in poor detection results, which are prone to missed or false detections. For pipelines of different diameters, different inspection devices need to be replaced, which increases the cost and difficulty of inspection. Utility Model Content

This allows for precise acquisition of the relative position between the detection ring and the pipeline, ensuring the pipeline remains centered within the detection ring and improving detection accuracy.

[0011] Preferably, the lateral telescopic mechanism and the detection ring are detachably connected via an adapter assembly, and the detection ring is located below the lateral telescopic mechanism.

[0031] Example 1

[0032] like Figures 1-2 As shown, a pipeline anti-corrosion coating status detection device includes a detection mechanism, a base 4, and a position adjustment mechanism. The detection mechanism includes a transmitter 1, a detection host 2, and a detection ring 3. The detection ring 3 is communicatively connected to the detection host 2. The base 4 is connected to a walking mechanism 5, and the detection host 2 is mounted on the base 4.

[0033] The detection mechanism is a mechanism for detecting the condition of the anti-corrosion coating of a pipeline through electrical signals. The transmitter 1 is used to be set on one end of the pipeline, and the detection ring 3 is used to be fitted on the pipeline to be detected. The conductive component 33 on the detection ring 3 contacts the outer wall of the pipeline. When the conductive component 33 on the detection ring 3 contacts the pipeline at the damaged part of the anti-corrosion coating, the pipeline, the conductive mechanism, the transmitter 1 and the detection host 2 form a circuit and conduct. An electrical signal fluctuation appears at the detection host 2. By detecting the fluctuating electrical signal, the condition of the anti-corrosion coating of the pipeline can be detected.

[0034] In one or more embodiments, the detection ring 3 may include a first half-ring 31 and a second half-ring 32. The combination of the first half-ring 31 and the second half-ring 32 can facilitate the fitting of the detection ring 3 onto the pipeline.

[0036] In an optional embodiment, the first half-ring 31 and the second half-ring 32 can be hinged on one side and detachably connected on the other side by a locking fastener.

[0037] In an optional embodiment, the conductive component 33 can be a conductive wire. The conductive wire is a long filament structure with multiple conductive wires arranged in a row. The conductive wire can make stable conductive contact with the outer wall of the pipe and can adapt to pipes of different diameters through its own flexible deformation characteristics, so that the detection ring 3 can be adapted to the detection of anti-corrosion layers of pipes of different diameters.

[0038] In an optional embodiment, the conductive wire can be inclined at less than 90° to the axial direction of the detection ring 3, so that the contact area between the conductive wire and the outer wall of the pipe is wider and more stable, and the detection ring 3 maintains a stable contact state with the pipe.

[0039] In an optional embodiment, a guide ring can be provided on the inner ring edge of the detection ring 3. The guide ring can be a ring-shaped structure protruding towards the inside of the detection ring 3. The guide ring can be detachably connected to the detection ring 3. The conductive wires can be distributed inside the guide ring to facilitate the replacement of the conductive component 33. Different conductive components 33 with different structures can be used to detect the pipeline anti-corrosion layer according to the actual situation.

[0040] In one or more embodiments, the detection host 2 is connected to the audible and visual alarm 9, which can promptly alert staff when damage to the anti-corrosion layer is detected.

[0041] In one or more embodiments, at least three distance detectors 34 are arranged at intervals along the circumference of the detection ring 3. The distance detectors 34 can accurately obtain the relative position of the detection ring 3 and the pipeline, so that the pipeline can be kept at the center of the detection ring 3, thereby improving the detection accuracy.

[0042] In an optional embodiment, three distance detectors 34 are evenly spaced along the inner circumference of the detection ring 3 on the center line of the width of the detection ring 3.

[0043] The base 4 is the main support of the device, used to support the position adjustment mechanism and the detection mechanism. The base 4 can be moved as a whole through the walking mechanism 5 set on the base 4.

[0045] In an optional implementation, the detection host 2 can be a horizontally placed box structure that can be stably mounted on the base 4.

[0047] In an optional embodiment, the walking mechanism 5 may include a roller 52 frame, a roller 52, and a drive mechanism 51. The drive mechanism 51 is connected to the roller 52 via a rotating shaft and is used to drive the roller 52 to rotate, thereby moving the base 4. The roller 52 frame is connected to the bottom of the base 4 and is used to mount the roller 52.

[0048] In one or more embodiments, the base 4 can be a box-type structure, and a power source can be installed inside the base 4 to provide power to the device. The power source can be electrically connected to the detection host 2 to provide power for the detection mechanism. The power source can also be electrically connected to the drive mechanism 51 to drive the roller 52 to roll.

[0049] In an optional implementation, the power source can be a battery, the base 4 can be a horizontally placed power box, the walking mechanism 5 is located at the bottom of the power box, and the detection host 2 can be located at the top of the power box.

[0050] The position adjustment mechanism is used to connect the detection ring 3. According to the height of the pipeline, the height of the detection ring 3 and the lateral distance relative to the pipeline are adjusted to achieve the relative position adjustment between the detection ring 3 and the pipeline, so that the pipeline can always be located in the center of the detection ring 3.

[0051] In one or more embodiments, the position adjustment mechanism may include a vertical telescopic mechanism 6 and a horizontal telescopic mechanism 7. The bottom of the vertical telescopic mechanism 6 is connected to the base 4 and the top is connected to the horizontal telescopic mechanism 7. The horizontal telescopic mechanism 7 is connected to the detection ring 3.

[0052] In an optional embodiment, the vertical telescopic mechanism 6 and the horizontal telescopic mechanism 7 can be electric telescopic rods. The vertical telescopic mechanism 6 is used to adjust the height of the detection ring 3, and the horizontal telescopic mechanism 7 is used to adjust the horizontal distance between the detection ring 3 and the base 4. By adjusting in both the vertical and horizontal directions, the detection ring 3 can be aligned with the center of the pipeline.

[0053] In an optional embodiment, the electric telescopic rods of the vertical telescopic mechanism 6 and the horizontal telescopic mechanism 7 can be equipped with driving components, and the height / length can be adjusted by powering the driving components with a power source.

[0054] In an optional embodiment, the lateral telescopic mechanism 7 can be detachably connected to the top of the detection ring 3 via the adapter component 8, so that after the detection ring 3 is set, it can be located below the lateral telescopic mechanism 7, thus avoiding positional interference between the position adjustment mechanism and the pipeline.

[0055] In an optional embodiment, the adapter assembly 8 may include a steering rod 81 and a connector 82. The steering rod 81 is connected to the groove of the lateral telescopic mechanism 7, and the connector 82 is connected to the detection ring 3. The steering rod 81 and the connector 82 are detachably connected.

[0056] In an optional embodiment, the steering rod 81 can be a rod-shaped structure bent at 90°. One end of the steering rod 81 can be coaxial with the lateral electric telescopic rod and connected in a groove. The connector 82 can be a structure set on the first half-ring 31, which can be plugged into the steering rod 81 and connected by bolts, threads or pins.

[0057] In one or more embodiments, the detection host 2 is connected to the controller 10, which allows for easier control of the detection process or its interruption.

[0058] In an optional implementation, the controller 10 can be connected to a power source, a drive mechanism 51, a position adjustment mechanism, and a distance detector 34 to enable on / off control of each component.

[0059] In an alternative implementation, the controller 10 may be a wired or wirelessly connected controller 10.

[0060] This embodiment of a pipeline corrosion protection layer condition detection device uses a traveling mechanism 5 to move a base 4, a detection host 2 on the base 4, and a detection ring 3 along the pipeline axis, avoiding manual handheld detection and making detection more convenient and labor-saving. Simultaneously, a position adjustment mechanism composed of a lateral telescopic mechanism 7 and a vertical telescopic mechanism 6 adjusts the position of the detection ring 3 relative to the pipeline, ensuring a stable relative state between the detection ring 3 and the pipeline during detection. This improves detection accuracy and avoids missed or false detections. In use, the vertical telescopic mechanism 6 and the lateral telescopic mechanism 7 are adjusted according to the pipeline height to ensure the first... Half-ring 31 and second half-ring 32 can be fitted onto the pipeline. The distance between them and the pipeline is detected by distance detector 34. If the distance is too large or too small, the vertical telescopic mechanism 6 and the horizontal telescopic mechanism 7 are adjusted to make the pipeline the center of the detection ring 3. Then, the transmitter 1 is connected to one end of the pipeline to emit an electrical signal, which drives the walking mechanism 5 to move the base 4 along the pipeline axis, thereby moving the detection ring 3 to detect the anti-corrosion layer. When the damaged part of the anti-corrosion layer contacts the conductive wire inside the detection ring 3, an electrical signal is transmitted to the detection host 2. The detection host 2 can obtain the electrical signal fluctuation and trigger the audible and visual alarm 9.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
