Description

Technical Field

[0001] This utility model relates to the field of pipeline corrosion detection technology, specifically an underground pipeline corrosion detection probe. Background Technology

[0002] Corrosion detection of underground pipelines is crucial for ensuring safety, extending service life, and reducing operational risks. Corrosion weakens pipe walls, potentially leading to leaks, ruptures, or even explosions, with potentially severe consequences, especially when transporting oil, gas, or chemicals. Regular inspections can detect corrosion early, preventing accidents and reducing maintenance costs and environmental hazards. Furthermore, corrosion products can clog pipelines, affecting transport efficiency, and inspection data can optimize maintenance plans and extend pipeline lifespan.

[0003] When conducting trenchless inspection of underground pipelines, an A-frame and a handheld detector are used together to inspect the pipeline. The inspector holds the A-frame in one hand and inserts it into the ground, while using the other hand to hold the handheld detector and inspect the ground. During the inspection, the inspector needs to keep holding the handheld detector and moving it, which is quite strenuous. At the same time, during the inspection, debris such as gravel on the ground may hit the sensor at the bottom of the detector probe, which may not only damage the equipment but also affect the accuracy and reliability of the inspection data.

[0004] To address the above issues, a corrosion detection probe for underground pipelines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion detection probe for underground pipelines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A corrosion detection probe for underground pipelines includes a detection probe and a sensor installed at the bottom of the detection probe. The bottom of the detection probe has a movable groove, and a protective frame plate is slidably connected in the movable groove. A positioning component for fixing the sliding of the protective frame plate is provided in the movable groove.

[0008] The positioning component includes guide blocks and positioning plates. Two sets of guide blocks are fixedly connected to both sides of the protective frame plate. The positioning plate is fixedly connected to the side of the guide block away from the protective frame plate. Guide grooves for sliding with the guide blocks are provided on both sides of the inner wall of the moving groove. The positioning plate is connected to one side of the detection probe through a connector.

[0009] Both sides of the protective frame are fixedly connected with locking blocks, and the locking blocks are equipped with casters.

[0010] In one alternative embodiment: the connector includes positioning holes and limit bolts, two sets of positioning holes are formed on one side of the positioning plate, and limit bolts are provided in the positioning holes. A number of limit holes for threaded connection with the limit bolts are provided on one side of the detection probe. The side of the positioning plate near the guide block slides with the outer wall of the detection probe.

[0011] In one alternative: a rotating block is rotatably connected to the opening of the card block, and the movable wheel is mounted on the bottom of the rotating block.

[0012] In one alternative: the bottom of the detection probe has a slot for engaging with the card block.

[0013] In one alternative: a plug hole is provided on one side of the card block, a fixing bolt is provided in the plug hole, and a fixing hole is provided on the rotating block for threaded connection with the fixing bolt.

[0014] In one alternative: a detector is mounted on top of the detection probe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention incorporates a protective frame, a sliding groove, a positioning component, a locking block, and sliding wheels. The positioning component positions the protective frame as it slides within the sliding groove, while the sliding wheels provide rotation, reducing fatigue for operators who hold the detector for extended periods. Adjusting the protective frame upwards facilitates sensor maintenance and replacement, while adjusting it downwards reduces the risk of damage from debris such as gravel on the ground, thus minimizing the impact on the accuracy and reliability of the detection data.

[0017] This utility model features a locking block, a movable wheel, a fixing hole, a plug-in hole, and a fixing bolt. The movable wheel is perpendicular to the ground, and the fixing bolt is inserted into the plug-in hole and the fixing hole on the rotating block for fixation. This supports the detection probe, while the locking block drives the movable wheel to rotate, making it convenient for maintenance personnel to inspect and replace the sensor.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 In this embodiment, an underground pipeline corrosion detection probe includes a detection probe 12 and a sensor 11 installed at the bottom of the detection probe 12. The bottom of the detection probe 12 is provided with a moving groove 14, and a protective frame plate 13 is slidably connected in the moving groove 14. A positioning component for fixing the sliding of the protective frame plate 13 is provided in the moving groove 14.

[0026] The positioning assembly includes guide blocks 15 and positioning plates 16. Two sets of guide blocks 15 are fixedly connected to both sides of the protective frame plate 13. The positioning plates 16 are fixedly connected to the side of the guide blocks 15 away from the protective frame plate 13. Guide grooves 17 for sliding with the guide blocks 15 are provided on both sides of the inner wall of the moving groove 14. The positioning plates 16 are connected to one side of the detection probe 12 through connectors. Pulling the positioning plates 16 causes the guide blocks 15 to slide downward in the guide grooves 17, thereby driving the protective frame plate 13 to slide downward in the moving groove 14. After sliding to a position where the gravel on the detection ground will not affect the sensor 11, the connectors fix the positioning plates 16, which can protect the sensor 11 and reduce the damage to the sensor 11 caused by the gravel on the detection ground.

[0027] Both sides of the protective frame plate 13 are fixedly connected with locking blocks 22, and the locking blocks 22 are provided with moving wheels 24.

[0028] The connector includes positioning holes 19 and limiting bolts 20. Two sets of positioning holes 19 are formed on one side of the positioning plate 16. Limiting bolts 20 are provided in the positioning holes 19. Several sets of limiting holes 18 are provided on one side of the detection probe 12 for threaded connection with the limiting bolts 20. The side of the positioning plate 16 near the guide block 15 slides against the outer wall of the detection probe 12. The limiting bolts 20 are disassembled using external tools to disengage them from the positioning holes 19 and the limiting holes 18. The positioning plate 16 is pulled, and after it moves to a suitable position, the limiting bolts 20 are inserted into the positioning holes 19 and the corresponding limiting holes 18 for fixation. This makes it easy to fix the positioning plate 16.

[0029] A rotating block 23 is rotatably connected to the opening of the card block 22. The movable wheel 24 is installed at the bottom of the rotating block 23. By setting the movable wheel 24, the movable wheel 24 rolls, reducing the fatigue of the testing personnel holding the detector 28 for a long time and improving work efficiency.

[0030] The bottom of the detection probe 12 is provided with a slot 21 for engaging the locking block 22. By setting the slot 21, the locking block 22 can be engaged in the slot 21, which reduces the impact on maintenance personnel when they are repairing or replacing the sensor 11 and facilitates operation.

[0031] The locking block 22 has a plug hole 26 on one side, and a fixing bolt 27 is provided in the plug hole 26. The rotating block 23 has a fixing hole 25 for threaded connection with the fixing bolt 27. The rotating block 23 drives the moving wheel 24 to rotate in the locking block 22. The moving wheel 24 is in vertical contact with the ground. The fixing bolt 27 is inserted into the plug hole 26 and the fixing hole 25 on the rotating block 23 for fixation. This can fix the rotating block 23, thereby making the moving wheel 24 roll more stably.

[0032] The detection probe 12 is equipped with a detector 28 on its top. By holding the detector 28 and moving the detection probe 12 close to the ground, the signal strength is monitored in real time. Near the damage point, the signal strength will change abruptly, and the detection probe 12 can accurately locate the center of the defect. The sensor 11, detector 28 and detection probe 12 are all prior art, and will not be described in detail in this application.

[0033] The working principle of this utility model is as follows: First, use external tools to disassemble the limit bolt 20, disengaging it from the positioning hole 19 and the limit hole 18. Pull the positioning plate 16, causing the guide block 15 to slide downwards in the guide groove 17, thereby driving the protective frame plate 13 to slide downwards in the moving groove 14. After sliding to a position where the detected ground debris will not affect the sensor 11, insert the limit bolt 20 into the positioning hole 19 and the corresponding limit hole 18 for fixation. Rotate the rotating block 23, causing it to drive the moving wheel 24 to rotate within the locking block 22, thus allowing the rotating block 23 to rotate. The sensor 11 is fixed by inserting the locking block 22 into the opening and the moving wheel 24 making vertical contact with the ground. The fixing bolt 27 is inserted into the insertion hole 26 and the fixing hole 25 on the rotating block 23 for fixation. This allows the testing personnel to easily move the detector 28 by hand. The moving wheel 24 rolls, reducing the fatigue of the testing personnel holding the detector 28 for a long time. At the same time, adjusting the protective frame plate 13 upwards makes it easier for the testing personnel to inspect and replace the sensor 11. Adjusting the protective frame plate 13 downwards reduces the damage to the sensor 11 caused by gravel and other debris on the testing ground, thereby affecting the accuracy and reliability of the testing data.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
