Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to a multi-angle monitoring acoustic probe. Background Technology

[0002] In urban centralized heating networks, heating wells are critical nodes, and the operational status of their internal pipes and equipment directly affects the stability and efficiency of heating. However, due to long-term exposure to high temperatures, high pressures, media corrosion, and external environmental factors, leaks are prone to occur in and around the heating wells. As a key node in the regional pipeline network, the presence of leaks can be detected by sound monitoring within the well. Leaks not only waste energy and increase operating costs but can also lead to safety accidents, severely impacting urban infrastructure and residents' lives. A search of existing Chinese patent technology, specifically the "Ultrasonic Probe for Pressure Vessel Pipeline" (publication number CN206321606U), reveals that this device involves attaching the wedge of a single-crystal angled probe to the inner wall of the pressure vessel pipeline, ensuring there is no gap between the wedge and the pipeline to prevent air reflection from affecting coupling and thus impacting the detection results. However, the complex environment of the thermal well chamber presents significant noise interference, making it difficult for a single sound acquisition method to comprehensively and accurately obtain sound signals, thereby affecting the accuracy of leak detection. Utility Model Content

[0003] Therefore, it is necessary to provide a multi-angle acoustic probe to address the problem that the complex environment of thermal well chambers has significant noise interference, and that a single sound acquisition method is insufficient to comprehensively and accurately acquire sound signals, thus affecting the accuracy of leak detection.

[0004] A multi-angle monitoring acoustic probe is provided, comprising: a housing, wherein a probe head is fixedly connected to the upper end of the housing; and a control mechanism, wherein the control mechanism is sleeved on the outside of the probe head, and the surface of the control mechanism extends to the lower part of the housing; wherein the control mechanism includes a noise reduction component disposed on the outside of the probe head, an angle component is mounted on the surface of the housing, the upper end of the angle component extends into the interior of the noise reduction component, the lower end of the angle component is connected to the control component, and an electric push rod is fixedly connected to the inner bottom wall of the control component.

[0005] In one embodiment, the control component includes a circular tube fixedly connected to the lower end of the angle component. The inner bottom wall of the circular tube is fixedly connected to the lower end of the electric push rod. A groove is provided on one side of the circular tube. A push frame is slidably connected to the inner wall of the groove. A connecting plate is fixedly connected to the surface of the push frame near the electric push rod. The connecting plate is fixedly connected to the upper end of the electric push rod.

[0006] In one embodiment, the angle assembly includes a connecting sleeve fixedly connected to the housing away from the surface of the probe head. The lower end of the connecting sleeve is fixedly connected to two movable arc plates. The lower ends of the movable arc plates extend to the bottom of the housing. The lower ends of the movable arc plates are fixedly connected to a circular arc plate. The two movable arc plates are symmetrically distributed along the axis of the circular arc plate.

[0007] In one embodiment, the noise reduction component includes a rubber sleeve fixedly connected to the surface of the probe head, the inner wall of the rubber sleeve being fixedly connected to the surface of the connecting sleeve, the surface of the rubber sleeve having multiple annular grooves, the multiple annular grooves being evenly distributed longitudinally along the surface of the rubber sleeve, and a silicone sleeve being fixedly connected to the surface of the rubber sleeve.

[0008] In one embodiment, the inner wall of the circular arc plate is rotatably connected to a connecting bolt, and the surface of the connecting bolt is connected to a fixing arc plate, and the two fixing arc plates are fixedly connected to the surface of the control component.

[0009] In one embodiment, the upper end of the pushing frame is hinged to an arc-shaped connecting rod, and the upper end of the arc-shaped connecting rod is fixedly connected to a circular sleeve.

[0012] Beneficial effects 1. The above-mentioned multi-angle monitoring acoustic probe, through the cooperation of the angle component and the adjustment component, can drive the connecting rod to shift by the arc-shaped connecting rod hinged at the upper end of the push frame against the round sleeve. This causes the connecting rod to drive the movable arc plate to rotate along the connecting bolt and align with a specific direction, effectively reducing the acquisition of interference sound from other directions. By flexibly adjusting the direction and angle of the probe, the pickup effect of the target sound is improved, ensuring the accuracy of leak detection. 2. By using the noise reduction components, a rubber sleeve can be fitted onto the outside of the housing. Multiple annular grooves on the outer surface of the rubber sleeve, together with the silicone sleeve, form multiple central cavities. These central cavities reduce external noise interference to the detector head. Furthermore, the set sound-collecting cones converge the sound in the detection direction, ensuring sound detection in a specific direction and improving the accuracy of leak detection.

The inner bottom wall of the circular tube 331 is fixedly connected to the lower end of the electric push rod 34. A groove 332 is provided on one side of the circular tube 331. A push frame 333 is slidably connected to the inner wall of the groove 332. A connecting plate 337 is fixedly connected to the surface of the push frame 333 near the electric push rod 34.

A circular sleeve 335 is fixedly connected to the upper end of the arc-shaped connecting rod 334. A connecting rod 336 is rotatably connected to the inner wall of the circular sleeve 335. The end of the connecting rod 336 is fixedly connected to the surface of the angle component 32. The angle assembly 32 includes a connecting sleeve 325 fixedly connected to the surface of the housing 1 away from the probe head 2. The lower end of the connecting sleeve 325 is fixedly connected to two movable arc plates 323. The lower end of the movable arc plates 323 extends to the bottom of the housing 1. The lower end of the movable arc plates 323 is fixedly connected to a circular arc plate 324. The two movable arc plates 323 are symmetrically distributed along the axis of the circular arc plate 324. The inner wall of the circular arc plate 324 is rotatably connected to a connecting bolt 322. The surface of the connecting bolt 322 is connected to a fixed arc plate 321. The two fixed arc plates 321 are fixedly connected to the surface of the control assembly 33. In this embodiment, the lower end of the fixed arc plate 321 is fixedly connected to the upper end of the circular tube 331, and the end of the connecting rod 336 is fixedly connected to the inner wall of the movable arc plate 323. The extension end of the driving electric push rod 34 drives the connecting plate 337 to move longitudinally inside the circular tube 331, so that the push frame 333 slides on the inner wall of the slide groove 332.

A sound-receiving cone 314 is fixedly connected to the inner wall of the silicone sleeve 313. The sound-receiving cone 314 is fixedly connected to the upper end of the rubber sleeve 311. In this embodiment, the device uses multiple annular grooves 312 on the outer surface of the rubber sleeve 311 to form multiple central cavities in conjunction with the silicone sleeve 313. The central cavities reduce external noise interference to the detector head 2, and the sound-collecting cone 314 converges the sound in the detection direction to ensure sound detection in a specific direction.

The connecting rod 336 drives the movable arc plate 323 to flip along the connecting bolt 322. The movable arc plate 323 drives the outer shell 1 to adjust the angle by ninety degrees through the connecting sleeve 325.
