Description

Technical Field

[0001] This utility model relates to the field of oil and gas pipeline inspection technology, and in particular to a penetration testing device for oil and gas pipelines. Background Technology

[0002] Chinese patent document CN222297701U discloses an oil and gas pipeline leak detector, which includes a detector body. A telescopic rod is located at the top of the detector body, and a probe is mounted on the top of the telescopic rod. Sleeves are located on both sides of the detector body. A sleeve is fitted around each of the two sleeves. A spring connected to a sleeve is located on the outer side of each sleeve, while a protective chamber is located on the inner side of each sleeve, which is close to the other. Through the cooperation of the sleeves, rods, springs, protective chambers, slots, L-shaped rods, and sleeves, the detector is protected externally. This reduces damage to the probe or scratches to the display screen in case of a fall, effectively ensuring the probe's lifespan and the accuracy of subsequent detections, and guaranteeing clear viewing on the display screen.

[0003] However, the probes in the aforementioned detectors cannot be adjusted relative to the user, which limits the detector's detection range. The back of oil and gas pipelines is difficult to detect, requiring the user to frequently change positions or adjust to an uncomfortable grip, which is time-consuming, labor-intensive, and inefficient. Therefore, we propose a penetration testing device for oil and gas pipelines. Utility Model Content

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a penetration testing device for oil and gas pipelines, including a handle 1, a positioning mechanism 9, a testing mechanism 8, and a locking mechanism 7. One end of the handle 1 has a movable rod 2 that can extend and retract. One end of the movable rod 2 is fixedly installed with a connector 3. A rotating part 4 is rotatably installed between the front and rear inner walls of the connector 3. A connecting column 5 is fixedly installed on the outer surface of the rotating part 4. A U-shaped plate 6 is fixedly installed at the bottom of the connecting column 5. The positioning mechanism 9 is set on the handle 1 and is used to adjust the extension length of the movable rod 2. The testing mechanism 8 is set on the U-shaped plate 6 and is used to test oil and gas pipelines. At least two sets of lighting lamps 12 are fixedly installed on the top inner side of the U-shaped plate 6. Two sets of anti-slip sleeves 14 are fixedly sleeved on the outer surface of the handle 1.

[0026] The snap-fit ​​mechanism 7 is located on the top of the connector 3. The snap-fit ​​mechanism 7 includes a snap-fit ​​plate 72. The snap-fit ​​plate 72 is located directly above the connector 3. At least two sets of snap-fit ​​grooves 10 are opened on the outer surface of the rotating part 4. The snap-fit ​​plate 72 is snapped into the corresponding snap-fit ​​groove 10. The top of the snap-fit ​​plate 72 is provided with a finger groove.

[0027] The snap-fit ​​mechanism 7 also includes a housing 71. The housing 71 is fixedly installed on the top of the connector 3. The snap-fit ​​plate 72 is movably extended and retracted on the housing 71. A spring assembly is fixedly installed between the snap-fit ​​plate 72 and the inner wall of the housing 71.

[0028] The testing mechanism 8 includes a testing instrument body 81, connecting pipes 82, and probes 83. The testing instrument body 81 is fixedly installed on the top inner side of the U-shaped plate 6. A set of probes 83 is fixedly installed on the inner walls of both sides of the U-shaped plate 6. A set of connecting pipes 82 is fixedly installed on the outer surfaces of both sides of the testing instrument body 81. One end of each set of connecting pipes 82 is fixedly connected to and communicates with the corresponding probe 83, and the other end of each set of connecting pipes 82 communicates with the testing end of the testing instrument body 81. A buzzer alarm 13 is fixedly installed on the top of the connector 3 and is electrically connected to the testing instrument body 81. Then, through the cooperation of the snap-fit ​​mechanism 7 and the detection mechanism 8, the angle of the probe 83 relative to the user can be adjusted with the rotating part 4, so as to adapt to the user's inconvenient holding posture. Moreover, with two sets of probes 83, it can detect the four sides of the oil and gas pipeline at one time. This solves the problem that the overall angle of some existing detectors relative to the user cannot be adjusted, which leads to the limited detection direction of the detector, the difficulty in detecting the back of the oil and gas pipeline, and the need for the user to frequently change positions or adjust to an uncomfortable holding posture, which is time-consuming, labor-intensive and has low detection efficiency. This improves the practicality of the device.

[0029] The positioning mechanism 9 includes a positioning rod 91, a handle 92, and a return spring 93. The positioning rod 91 is movably inserted through the handle 1. At least two sets of positioning holes 11 are opened on the outer surface of the movable rod 2. One end of the positioning rod 91 is inserted into the corresponding positioning hole 11, and the other end of the positioning rod 91 is fixedly installed with the handle 92. The return spring 93 is sleeved on the positioning rod 91. One end of the return spring 93 is fixedly connected to the outer surface of the handle 1, and the other end of the return spring 93 is fixedly connected to the handle 92. Through the positioning mechanism 9, the length of the movable rod 2 extending from the handle 1 can be adjusted, and the distance between the detection position and the user can be adjusted, which improves the flexibility of the device. At the same time, with the help of the lighting lamp 12, it is convenient for the user to use the device at night, ensuring the effectiveness of the device and facilitating its promotion and use.

[0030] Working principle: When adjusting the angle of probe 83, move the snap-fit ​​plate 72 to retract it into the housing 71 so that it no longer locks the snap-fit ​​groove 10. At this time, rotate the connecting piece 3 on the rotating piece 4 to release the snap-fit ​​plate 72. The spring assembly in the housing 71 will cause the snap-fit ​​plate 72 to reset and lock into the corresponding snap-fit ​​groove 10. When adjusting the extension length of the movable rod 2, pull the handle 92 to drive the positioning rod 91 to disengage from the positioning hole 11. At this time, slide the movable rod 2 relative to the grip 1 and release the handle 92. The reset spring 93 will cause the positioning rod 91 to reset and lock into the corresponding positioning hole 11. During testing, the user holds the grip 1 so that the two sets of probes 83 are located on both sides of the oil and gas pipeline for testing.
