Description

Technical Field

[0001] This application relates to the field of leak detection device technology, and in particular to a high-pressure pipeline leak detection device based on acoustic signature. Background Technology

[0002] Leak detection in pressure pipelines is an effective method for detecting leaks and preventing pipe bursts, and it is of great significance for ensuring the safe operation of pipelines and reducing pipeline leakage rates. The pipelines in question include existing pressure pipelines in industries such as water diversion, water supply, and heating. Existing leak detection instruments, such as leak detectors and correlators, use sound sensors to detect leaks by sound emitted from the outer wall of buried pressure pipelines or the road surface above the pipeline. However, background noise from the external environment, especially noise from vehicles on the road, severely affects the accuracy and efficiency of the detection. Furthermore, because buried pipelines are linear, and traditional sensors such as leak detectors and correlators are point-based, the detection efficiency is low, and even if a leak is found in a section of the pipeline, the leak cannot be precisely located. Traditional leak detection methods require a large number of workers to search for leaks along roads late at night, which is not only dangerous and arduous but also highly dependent on the workers' experience, resulting in low accuracy.

[0003] The intelligent detection and location device for leaks in long-distance pipelines disclosed in the authorization announcement number CN110987318B uses a sound receiver to collect the buzzing sound when a leak occurs, and then locates the leak location. However, its clamp size is fixed, and it is very cumbersome to replace different clamps for pipelines with different inner diameters. Utility Model Content

[0004] To achieve the above objectives, this application proposes a high-pressure pipeline leakage detection device based on acoustic signature, comprising an upper ring plate, a lower ring plate, a sound receiver, a control box, and a locking assembly; the upper ring plate, the control box, and the sound receiver are arranged sequentially from bottom to top; the locking assembly is configured to ensure that the upper and lower ring plates are tightly attached to the upper and lower end faces of the pipeline.

[0005] Through the cooperation of the upper and lower ring plates and the locking assembly, the device can fit tightly against the pipe surface, ensuring that the sound receiver can accurately capture the acoustic signature signal generated by the leak. This structural design provides a stable physical basis for subsequent acoustic signature analysis, avoiding signal distortion caused by device loosening. At the same time, the bottom-up layered layout (upper ring plate → control box → sound receiver) optimizes the sound signal transmission path and reduces interference from intermediate links.

[0006] Specifically, the locking assembly includes a pull strap and a screw; the pull strap is wound around the screw, and the screw is configured to adjust the number of turns of the pull strap.

[0007] The above technical solution, with its combination of a pull belt and a screw, allows the device to adapt to pipes of different diameters by adjusting the number of pull belt windings.

[0008] Specifically, the arc range of the upper and lower ring plates is 10 to 15°, and the chord length is 60 ± 5 mm.

[0009] The 10°–15° arc range and 60±5mm chord length allow the ring to better conform to the outer contour of the circular pipe. This design ensures sufficient contact area while avoiding installation difficulties caused by excessive curvature.

[0010] Specifically, the control box has a built-in wireless transmitter that transmits data with the central server.

[0011] Specifically, the control box is a hollow cavity with a gravity ball inside, which is connected to and suspended from the cavity by a wire.

[0012] In the above technical solution, the gravity ball is suspended inside the control box by a connecting wire, which can monitor the tilt status of the device in real time. When the device shifts due to improper installation or pipeline vibration, the change in the position of the gravity ball will trigger an alarm or automatic calibration mechanism to ensure that the sound receiver is always in the optimal detection position.

[0013] Specifically, the front and rear ends of the cavity are equipped with transparent plates, and the transparent plates are removable.

[0014] In the above technical solution, the detachable transparent panel allows operators to directly observe the state of the gravity ball, enabling them to determine its levelness without disassembling the device. Simultaneously, the transparent panel facilitates cleaning of internal dust or replacement of components, reducing maintenance costs.

[0015] Specifically, it also includes: a counterweight box; the counterweight box is located on the lower end face of the lower ring plate.

[0016] In the above technical solution, the counterweight box increases the overall weight of the device, thereby enhancing its adhesion to the pipeline and effectively resisting the vibration or airflow impact of the high-pressure pipeline.

[0017] Specifically, the locking components are symmetrically arranged on both sides of the control box and the lower ring plate.

[0018] In the above technical solution, the symmetrically arranged locking components ensure that the pressure is evenly distributed on both sides of the pipeline, avoiding the device tilting caused by unilateral force.

[0019] Specifically, it also includes a connecting column; the two ends of the connecting column are respectively connected to the upper ring plate and the control box.

[0020] Specifically, it also includes a locking plate; the locking plate is located on the outside of the screw and is configured to fix the pull strap. The locking plate prevents the pull strap from loosening after adjustment by mechanical locking.

[0021] Compared with the prior art, the advantages of this application are:

[0022] (1) This solution can flexibly adapt to high-pressure pipelines of different diameters through adjustable locking components (pull strap + screw + locking plate) and symmetrical design. During installation, the number of turns of the pull strap can be adjusted by the screw, and the locking plate can be used to prevent loosening. This solves the problem of traditional devices being "one device per pipe" or easily loosening after installation, and greatly improves the applicability of the device.

[0023] (2) The counterweight box and the lower ring plate work together to lower the center of gravity and enhance the vibration resistance of the device;

[0024] (3) The gravity ball suspension design monitors the installation posture in real time, and the transparent plate facilitates intuitive calibration, avoiding signal deviation caused by offset. Attached Figure Description

[0036] In the above technical solution, the gravity ball 2 is suspended inside the control box 4 by a connecting wire, which can monitor the tilt status of the device in real time. When the device shifts due to improper installation or pipeline vibration, the change in position of the gravity ball 2 will trigger an alarm or automatic calibration mechanism to ensure that the sound receiver 1 is always in the optimal detection position.

Simultaneously, the transparent plate facilitates cleaning of internal dust or replacement of components, reducing maintenance costs.

[0039] Specifically, it also includes: a counterweight box 8; the counterweight box 8 is located on the lower end face of the lower ring plate 6.

[0040] In the above technical solution, the counterweight box 8 increases the overall weight of the device, thereby enhancing its adhesion to the pipeline and effectively resisting the vibration or airflow impact of the high-pressure pipeline.

[0041] Specifically, the locking components 3 are symmetrically arranged on both sides of the control box 4 and the lower ring plate 6.

[0042] In the above technical solution, the symmetrically arranged locking components 3 ensure that the pressure is evenly distributed on both sides of the pipeline, avoiding the tilting of the device caused by unilateral force.
