Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] Please see Figure 1-5As shown, a non-destructive testing device for natural gas pipelines includes a handle 1, a housing 2 fixedly connected to the outside of the handle 1, and rotating shafts 3 symmetrically rotatably connected inside the housing 2. Arc-shaped plates 4 are fixedly connected to the outer sides of the two rotating shafts 3 extending to the outside of the housing 2. A rotating roller 6 is rotatably connected inside the handle 1, and a connecting line 7 is wound around the outside of the rotating roller 6. A detection component is disposed within the handle 1 and the arc-shaped plates 4. A limit component is disposed on the inner side of the arc-shaped plates 4. An adjustment component is disposed inside the housing 2. The detection component includes an infrared gas sensor 5 and an ultrasonic sensor 8. The infrared gas sensor 5 is equidistantly installed on the inner side of the arc-shaped plates 4, and the ultrasonic sensor 8 is installed at one end of the connecting line 7. The limiting component includes a limiting frame 9, which is fixedly connected to the inner side of the arc plate 4 and located on both sides of the infrared gas sensor 5. Rollers 10 are installed at equal intervals on the inner sides of the two limiting frames 9. The adjusting component includes a connecting rod 11, which is fixedly connected to the outer side of the two rotating shafts 3 away from the arc plate 4. A sliding shaft 12 is fixedly connected to one end of the two connecting rods 11. Push rods 13 are slidably connected to both sides of the outer side of the housing 2. A sliding groove 14 is opened in the inner side of the housing 2 at one end. The two sliding shafts 12 are slidably connected to the inner side of the corresponding sliding groove 14. Springs 15 are provided on both sides of the inner side of the housing 2 near the two push rods 13.

[0026] When performing a natural gas pipeline leak detection operation, loosen bolt 18, remove the protective cover 17, press the two push rods 13 inwards, causing the sliding shaft 12 to slide inside the sliding groove 14, simultaneously compressing the springs 15 on both sides, causing the springs 15 to deform. This deforms the springs 15, which in turn causes the rotating shaft 3 and the arc plate 4 to rotate via the connecting rod 11, thus opening the two arc plates 4. Then, bring the two arc plates 4 close to the natural gas pipeline, positioning them on either side of the pipeline. Then, release the two push rods 13; the rebound force of the springs 15 will cause the arc plates 4 to rotate inwards again until the two arc plates... The curved plate 4 surrounds the natural gas pipeline. When the pipeline diameter is large, the two limiting brackets 9 can contact the outer wall of the pipeline and limit the movement of the curved plate 4. Multiple rollers 10 facilitate the movement of the curved plate 4 outside the natural gas pipeline. The two curved plates 4 can be manually moved outside the natural gas pipeline using the handle 1. An infrared gas sensor 5 can then detect leaks in the natural gas pipeline. When a leak is detected, the infrared gas sensor 5 senses it and transmits the data to the control panel 20 for display, allowing staff to observe the leak. After the leak detection is completed, the above operation can be repeated to detach the arc plate 4 from the pipeline. When it is necessary to detect the wall thickness or defects of the natural gas pipeline, open the sealing cover 19 and pull the connecting wire 7 outward. The ultrasonic sensor 8 can then be used to detect the wall thickness or defects of the natural gas pipeline. During the wall thickness or defect detection, the ultrasonic sensor 8 can also transmit the detected data to the control panel 20 for display. After the wall thickness or defect detection is completed, release the connecting wire 7. Under the rebound force of the torsion spring, the connecting wire 7 and the ultrasonic sensor 8 will be reset. Then, close the sealing cover 19 to realize the ultrasonic... Similarly, to protect the ultrasonic sensor 8, the protective cover 17 is reinserted into the mounting cover 16 and the bolts 18 are tightened. The protective cover 17 can protect the arc plate 4 and the infrared gas sensor 5. This effectively prevents the ultrasonic sensor 8 and the infrared gas sensor 5 from being exposed to the outside world and easily damaged by collisions with external objects when the device is not in use. This improves the safety and service life of the device. In addition, the device is small, lightweight, and easy to operate, providing convenience for workers in complex environments such as the field and mountains, and effectively reducing the technical threshold for operators.

[0027] Among them, a torsion spring is provided at the rotation connection between the rotating roller 6 and the handle 1. The outer part of the limiting frame 9 is an arc-shaped structure that cooperates with the arc plate 4. The outer part of the housing 2 is fixedly connected to the mounting cover 16. The outer part of the mounting cover 16 is detachably connected to the protective cover 17. The inner part of the mounting cover 16 extends into the inner part of the protective cover 17 and is threaded with bolts 18. A sealing cover 19 is installed on the outer side of the handle 1 near the rotating roller 6. A control panel 20 is installed on the outer side of the handle 1.

[0028] The above technical solution allows for easy operation by staff through the control panel 20, enabling them to intuitively observe the detection results and display the real-time monitoring results of the ultrasonic sensor 8 and the infrared gas sensor 5. This facilitates timely understanding of the pipeline situation and decision-making by management personnel.

[0029] Example 2

[0030] Please see Figure 1 As shown in the first embodiment, as another implementation of this utility model, the bottom sides of the handle 1 are equipped with straps 21, and the outer sides of the two straps 21 are respectively provided with buckles and holes, and the outer side of the handle 1 is provided with anti-slip texture.

[0031] When in operation, the two straps 21, along with the buckles and holes, make it easy to carry and fix the device in a certain position, thus improving its portability, as well as its lightweight, easy-to-carry and operable performance.

[0032] Working principle: When a natural gas pipeline leak is detected, loosen bolt 18, remove the protective cover 17, press the two push rods 13 inward, causing the sliding shaft 12 to slide inside the sliding groove 14, simultaneously compressing the springs 15 on both sides, causing the springs 15 to deform. This, through the connecting rod 11, drives the rotating shaft 3 and the arc plate 4 to rotate, causing the two arc plates 4 to open. Then, bring the two arc plates 4 close to the natural gas pipeline, so that the two arc plates 4 are on both sides of the natural gas pipeline. Then, release the two push rods 13, and under the rebound force of the springs 15, the arc plates 4 will rotate inward again until the two arc plates 4 completely surround the natural gas pipeline. When the diameter of the natural gas pipeline is large, the two limit brackets 9 can be used to... The arc plate 4 is placed in contact with the wall and is limited in position. Multiple rollers 10 facilitate its movement outside the natural gas pipeline. The two arc plates 4 are manually moved outside the pipeline using the handle 1, allowing the infrared gas sensor 5 to detect leaks. When a leak is detected, the infrared gas sensor 5 senses it and transmits the data to the control panel 20 for display by staff. After leak detection, the above operation can be repeated to detach the arc plate 4 from the pipeline. When wall thickness or defect detection is required, the sealing cover 19 is opened, and the connecting wire 7 is pulled outwards, allowing the ultrasonic sensor 8 to detect leaks. For natural gas pipeline wall thickness or defect detection, the ultrasonic sensor 8 transmits the detected data to the control panel 20 for display. After the wall thickness or defect detection is completed, the connecting wire 7 is released, and the torsion spring returns the connecting wire 7 and the ultrasonic sensor 8 to their original positions. Then, closing the sealing cover 19 protects the ultrasonic sensor 8. Similarly, re-inserting the protective cover 17 into the mounting cover 16 and tightening the bolts 18 protects the arc plate 4 and the infrared gas sensor 5. This effectively prevents the ultrasonic sensor 8 and the infrared gas sensor 5 from being exposed to the outside world and easily damaged by collisions when the device is not in use. This device improves safety and lifespan, and its compact size and lightweight design make it easy to operate, providing convenience for workers in complex environments such as the field and mountains. It also effectively reduces the technical barrier for operators. The control panel 20 allows for easy operation and intuitive observation of the detection results. It can also display the real-time monitoring results of the ultrasonic sensor 8 and the infrared gas sensor 5, enabling managers to understand the pipeline situation and make decisions in a timely manner. The two straps 21, along with buckles and holes, make it easy to carry and fix the device in a certain position, improving its portability, lightness, ease of carrying, and operability.
