Description

Technical Field

[0001] This utility model relates to the field of pulsed eddy current detection technology, specifically to a mechanism for assisting in the detection of high-altitude pipelines using pulsed eddy current. Background Technology

[0002] Pulsed eddy current technology is a measurement method for online non-destructive testing of pipelines, tanks, towers, and other structures. Compared with other corrosion testing methods, eddy current testing technology has advantages such as fast detection speed, high accuracy, and less susceptibility to external influences. Pulsed eddy current technology can achieve both line and area scanning, improving overall work efficiency, while also exhibiting excellent technical characteristics in measurement accuracy and reproducibility. Pulsed eddy current technology has been widely used in refining, chemical, power plant, and nuclear industries, and its advanced technology ensures comprehensive, uniform, and rapid scanning and positioning of pipelines or containers.

[0003] However, in practical applications, there may be situations where the pipeline is too high or too long, requiring the pre-construction of scaffolding, lifting platforms, or the use of aerial work vehicles, which significantly increases labor costs. Furthermore, the high-altitude environment is affected by factors such as wind, temperature, and sunlight, making manual operation prone to falls due to fatigue or imbalance.

[0004] Therefore, how to provide a mechanism for assisting pulsed eddy current detection of high-altitude pipelines and overcome the shortcomings of existing technologies is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, this utility model provides an auxiliary pulse eddy current detection mechanism for high-altitude pipelines to solve the problems in the prior art, which require the construction of climbing devices for detecting excessively high and long pipelines, resulting in high labor costs and certain dangers in high-altitude detection.

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

[0007] This utility model discloses a mechanism for assisting pulsed eddy current detection of high-altitude pipelines, comprising:

[0008] The outer shell is a hollow structure with an opening on one side, and guide rollers are respectively provided on the two opposite outer side walls of the outer shell;

[0009] The detection module is installed inside the housing;

[0010] Locking components, arranged in pairs, are installed on the outer side wall of the housing, and several housings are connected end to end by the locking components;

[0011] A support telescopic device is movably connected to the outer wall of the housing, and the support telescopic device pushes the housing to move along the pipe.

[0012] Furthermore, the detection module includes:

[0013] The pulsed eddy current probe is installed inside the housing;

[0014] A quick-connect fitting is installed inside the housing and electrically connected to the pulsed eddy current probe. The detection module is connected to an external pulsed eddy current detector via the quick-connect fitting.

[0015] Furthermore, the locking assembly includes a pin, a fastening nut, and a locking pin hole. The locking pin holes are located on two opposite outer side walls of the housing. The pin passes through two adjacent sets of locking pin holes in sequence, and the end of the pin is threadedly connected to a fastening nut.

[0016] Furthermore, the support telescopic device includes a universal joint, a telescopic rod, and a support threaded hole. The support threaded hole is located on the outer side wall of the housing. One end of the universal joint is internally threaded into the support threaded hole, and the other end of the universal joint is connected to the telescopic rod.

[0017] Furthermore, the guide roller is arranged along the axial direction of the pipe.

[0018] Furthermore, three or more of the aforementioned outer shells are interconnected.

[0019] This utility model has the following advantages:

[0020] This invention, by incorporating a detection module, locking assembly, and support telescopic device, can be used in conjunction with an external pulse eddy current detector, allowing inspectors to operate the device from the ground to inspect excessively high and long pipelines. The use of pins and fastening nuts enables quick connection of multiple detection modules, flexibly adapting to high-altitude pipelines of varying diameters, eliminating the cumbersome process of manual segmented inspection, and increasing the operational coverage. The use of universal joints and telescopic rods, along with guide rollers, replaces manual climbing operations, saving on scaffolding erection and lifting platform rental costs, reducing labor costs, and minimizing the possibility of injury from manual climbing.

[0032] Please refer to Figures 1-7 The present invention discloses a mechanism for assisting in the detection of high-altitude pipelines using pulsed eddy currents. This invention consists of five parts, as follows: Figure 1 , Figure 2As shown, the device includes a housing 1, guide rollers 5, a detection module 4, locking components 2, and a support telescopic device 3. The housing 1 is a hollow structure with an opening on one side. Guide rollers 5 are respectively provided on the two opposite outer walls of the housing 1. The detection module 4 is installed inside the housing 1. The locking components 2 are arranged in pairs and installed on the outer walls of the housing 1. Several housings 1 are connected end to end through the locking components 2. The support telescopic device 3 is movably connected to the outer walls of the housing 1 and pushes the housings 1 to move along the pipeline. In this embodiment, preferably, three or more housings 1 are connected together. The number of housings 1 is three or more, and at least three housings 1 are required to encircle the pipeline end to end. The housings 1 can be freely assembled. The appropriate number of housings 1 is selected according to the diameter of the pipeline to be detected until the pipeline is completely surrounded. The diameter of the pipeline to be detected is greater than 50mm. At the same time, the number of probes required to work can be selected as needed. The guide rollers 5 are arranged along the axial direction of the pipeline. In use, the appropriate amount of the outer shell 1 is fixed by the locking component 2, and most of the guide rollers 5 are in contact with the pipe. The outer shell 1 is pushed along the pipe by the support telescopic device 3, and the detection module 4 inside the outer shell 1 can then detect the pipe.

[0033] Based on the previous embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the detection module 4 includes a pulsed eddy current probe 41 and a quick connector 42. The pulsed eddy current probe 41 is installed inside the housing 1, and the quick connector 42 is installed inside the housing 1 and electrically connected to the pulsed eddy current probe 41. The detection module 4 is connected to an external pulsed eddy current detector through the quick connector 42. The detection end of the pulsed eddy current probe 41 detects the pipe through the opening of the housing 1. The quick connector 42 is a common electrical interface in the art. The detection data of the pulsed eddy current probe 41 is transmitted through the quick connector 42. The detection module 4 can be connected to the external pulsed eddy current detector through the quick connector 42 using a wired or wireless connection.

[0034] Based on the previous embodiment, such as Figure 5 , Figure 6 , Figure 7 As shown, the locking assembly 2 includes a pin 21, a fastening nut 22, and locking pin holes 23. The locking pin holes 23 are located on two opposite outer side walls of the housing 1. The pin 21 passes through two adjacent sets of locking pin holes 23 in sequence, and the end of the pin 21 is threadedly connected to the fastening nut 22. The locking assembly 2 is used for connection and fixation between housings 1. The specific location of the locking pin holes 23 is shown in the figure. Figure 5As shown, the locking pin holes 23 on both sides of the same outer shell 1 are staggered. The pin body 21 passes through the locking pin holes 23 of two adjacent outer shells 1 at the same time. The lower end of the pin body 21 is threaded, and the fastening nut 22 is threaded to the lower end of the pin body 21, so that the two outer shells 1 form a movable connection.

[0035] Based on the previous embodiment, such as Figure 1 , Figure 2 As shown, the support telescopic device 3 includes a universal joint 31, a telescopic rod 32, and a support threaded hole 33. The support threaded hole 33 is located on the outer wall of the outer casing 1. One end of the universal joint 31 is internally threaded into the support threaded hole 33, and the other end of the universal joint 31 is connected to the telescopic rod 32. The support threaded hole 33 is located on the outside of the outer casing 1 and is used to connect the external support telescopic device 3. The support telescopic device 3 consists of the universal joint 31 and the telescopic rod 32. The universal joint 31 is used to connect the support threaded hole 33 of the outer casing 1 and the telescopic rod 32, and can adjust the angle according to the required direction and other requirements during operation. The telescopic rod 32 is used to support the outer casing 1 and has a telescopic function. For high-altitude pipelines, it can push the outer casing 1 along the pipeline as it extends and retracts, thereby realizing the inspection of high-altitude pipelines. The maximum extension height of the telescopic rod 32 can reach 20 meters. For the use of the support telescopic device 3, it is manually operated. Using manual driving force, the device is extended or retracted, thereby driving the movement of the outer casing 1, thus realizing the inspection of high-altitude pipelines.

[0036] The usage process of this utility model embodiment is as follows:

[0037] Secure the appropriate amount of outer casing 1 with locking assembly 2, and ensure that most of the guide rollers 5 are in contact with the pipe; fix the universal joint 31 of the support telescopic device 3 with the support threaded hole 33 on the outer casing 1 to ensure a stable connection; select the number of detection modules 4 to be used according to the detection requirements, and connect the external pulse eddy current detector through quick connector 42; start the pulse eddy current detector to work, and manually operate the support telescopic device 3 to drive the device to extend or retract, thereby driving the movement of the outer casing 1, thus enabling the detection of pipelines at height.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
