Description

Technical Field

[0001] This utility model relates to the field of positioning instrument technology, and in particular to a precise positioning instrument for pipeline leaks. Background Technology

[0002] Pipelines are tubular structures used to transport fluids. They consist of pipes, fittings, valves, and other accessories. They can be classified according to material, purpose, and pressure rating. They are characterized by strong sealing, high transport efficiency, and long-distance transmission capability. They are widely used in energy, chemical, construction, and municipal sectors and are an important component of modern industrial and urban infrastructure. Their design and installation must comply with relevant standards to ensure safe and stable operation.

[0003] Pipeline leak location locators are professional detection devices used to quickly and accurately determine the location of various pipeline leaks. They are widely used in municipal, industrial, and construction fields, integrating multiple advanced technologies. For example, acoustic wave sensing-based devices can capture the unique sound or vibration signals generated by pipeline leaks, filtering environmental noise interference through digital signal processing technology to enhance leak characteristics. Focused current scanning devices locate leaks by measuring the leakage current passing through the leak point as a focused electrode array probe moves within the pipeline in real time. Some also combine multi-sensor fusion, such as compatible video and sonar detection, along with listening and positioning modules, to achieve accurate judgment of leaks and other internal pipeline defects. They possess high sensitivity and can detect minute leaks. With small leaks and strong anti-interference capabilities, it can adapt to various scenarios such as hard surfaces and grass. The error range is usually small, and some can reach centimeter-level accuracy, which greatly improves pipeline maintenance efficiency and reduces resource waste and safety hazards. In use, traditional metal probes are mostly rigid structures. When there are curvature changes on the pipeline surface or when it is covered with anti-corrosion or insulation layers, the probe cannot fit completely, resulting in signal transmission loss. In the existing technology, for complex pipelines, ground acoustic wave detection and pipeline crawler detection can be combined to cross-verify the leak location by synchronizing positioning data. However, when the detector is placed on the pipeline, the non-rigid contact will become a transmission channel for external vibrations, and noise signals will mix into the detection data, affecting the accuracy of the data.

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a pipe leak location instrument, including a housing 1 and a detector 2. A connecting mechanism 3 is provided on the outside of the detector 2 for installing and connecting the detector 2. A partition mechanism 4 is provided inside the housing 1 for partitioning the space inside the housing 1. The connecting mechanism 3 includes a fixing block 301, which is located at the rear right side of the detector 2. A rotating rod 302 is rotatably connected to the front side of the fixing block 301. A turntable 303 is fixedly connected to the front side of the rotating rod 302. A connecting rope 304 is provided on the outside of the rotating rod 302. A magnet block 305 is fixedly connected to the other end of the connecting rope 304. A magnet block 306 is installed on the left side of the detector 2. A sliding groove 11 is provided inside the housing 1, which is located on the outside of the turntable 303. A locking rod 12 is slidably connected inside the sliding groove 11. The rear end of the locking rod 12 is locked to the front left end of the fixing block 301. The locking rod 12 can play a locking role.

[0032] Specifically, during the installation of detector 2, the operator rotates turntable 303, which causes the connected rotating rod 302 to rotate accordingly, further causing the connecting rope 304 to wind and unwind. The other end of the connecting rope 304 is connected to magnet block 305, and detector 2 is also equipped with magnet block 306. When magnet block 305 and magnet block 306 approach each other, the attraction of the magnetic force makes the two fit tightly together. Through this magnetic force, detector 2 is firmly fixed to the outer wall of the pipe, ensuring stable contact between the sensor and the pipe during the detection process.

[0033] Reference Figure 2 , Figure 3 and Figure 5The partition mechanism 4 includes a knob 401. A threaded rod 402 is fixedly connected to the left side of the knob 401. Rotating the knob 401 causes the threaded rod 402 to rotate. A movable plate 403 is provided on the outer side of the threaded rod 402. A rotating rod 404 is provided in the middle of the movable plate 403. A connecting plate 405 is rotatably connected to both the left and right sides of the rotating rod 404. A rotating shaft 406 is rotatably connected to the outer side of the connecting plate 405. A connecting plate 407 is rotatably connected to the outer side of the rotating shaft 406. Limiting rods 5 are fixedly connected to the front and rear sides of the interior of the housing 1. The outer side of the limiting rod 5 is slidably connected to the outer side of the movable plate 403 to play a limiting role.

[0034] Specifically, rotating the knob 401 drives the threaded rod 402 to rotate, which in turn causes the outer movable plate 403 to move along the axial direction of the threaded rod 402. The movement of the movable plate 403 pushes the central rotating rod 404 to move synchronously. The connecting plates 405 on the left and right sides of the rotating rod 404 drive the connecting plates 407 to rotate and unfold through the rotating shaft 406. As the knob 401 continues to rotate, the connecting plates 407 gradually form a partition, dividing the internal space of the box 1 into multiple independent areas. By controlling the rotation direction and angle of the knob 401, the degree of unfolding of the partition structure can be adjusted, thereby effectively dividing the internal space of the box 1. Inside the box 1, there are limiting rods 5 fixedly connected to the front and rear sides. The outer side of the limiting rod 5 is slidably connected to the outer side of the movable plate 403 to achieve the limiting function.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Hinges 6 are fixedly connected to the left and right rear ends of the box body 1. A cover plate 7 is fixedly connected to the outside of the hinge 6. A buckle 8 is fixedly connected to the middle of the front side of the cover plate 7. A retaining ring 9 is fixedly connected to the upper middle of the front side of the box body 1. The buckle 8 can engage with the retaining ring 9. Corner guards 13 are provided at the four corners of the bottom of the box body 1. Screws 10 are threadedly connected to the outside of the corner guards 13. The corner guards 13 are fixed by the screws 10.

[0036] Specifically, hinges 6 are provided on both the left and right sides of the rear side of the box body 1. A cover plate 7 is fixedly installed on the outside of the hinge 6. A buckle 8 is provided in the middle of the front side of the cover plate 7. A retaining ring 9 is provided in the upper middle of the front side of the box body 1. The buckle 8 and the retaining ring 9 can be engaged. Corner guards 13 are provided at the four corners of the bottom of the box body 1. The outer side of the corner guards 13 is connected to the screws 10 by threads, and the corner guards 13 are fixed by the screws 10.

[0037] Working principle: During the installation of detector 2, the operator rotates the turntable 303, which will cause the rotating rod 302 fixed thereto to rotate as well. This will cause the connecting rope 304 to wind and unwind. The other end of the connecting rope 304 is connected to magnet block 305. Magnet block 306 is also installed on detector 2. When magnet block 305 and magnet block 306 approach each other, the magnetic attraction makes them stick together. The detector 2 is rigidly fixed to the outer wall of the pipe by magnetic force, ensuring that the sensor maintains stable contact with the pipe during the detection process.

[0038] Rotating the knob 401 drives the threaded rod 402 to rotate, which in turn drives the outer movable plate 403 to move axially along the threaded rod 402. The movable plate 403 pushes the central rotating rod 404 to move synchronously. The connecting plate 405 on the left and right sides of the rotating rod 404 drives the connecting plate 407 to rotate and unfold through the rotating shaft 406. As the knob 401 continues to rotate, the connecting plate 407 gradually forms a partition, dividing the internal space of the box 1 into multiple independent areas. By controlling the rotation direction and angle of the knob 401, the degree of unfolding of the partition structure can be adjusted to achieve the partitioning of the internal space of the box 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
