However, these underground spaces often face complex environments characterized by dampness, confinement, and high electromagnetic interference, making it difficult to detect potential equipment malfunctions through manual inspections. In recent years, acoustic signature detection technology has been widely applied to tunnel and utility tunnel inspections. Typically, acoustic signature detectors are mounted on inspection robots, which then move the detectors within the tunnel.

[0003] Currently, the connection structures used to fix the voiceprint detector to the inspection robot are all fixed connections, making it difficult to adjust the angle of the voiceprint detector according to actual needs. Utility Model Content

[0036] like Figures 1-8 As shown, an embodiment of this utility model provides an angle adjustment structure, including:

[0037] Fastener 1;

[0038] Shaft 2;

[0039] The rotating component 3 has a cylindrical through hole 31 at one end corresponding to the rotating shaft 2. The inner wall of the cylindrical through hole 31 has a notch 32. The rotating shaft 2 is rotatably disposed in the cylindrical through hole 31, and the part of it located in the notch 32 is connected to the fixing component 1.

[0040] The connector 4 has one end detachably connected to the end of the rotating shaft 2 located in the cylindrical through hole 31. The rotating member 3 has multiple connecting parts. When the rotating member 3 rotates relative to the fixed member 1, any of the connecting parts can rotate to be detachably connected to the other end of the connector 4.

[0041] In this embodiment, the rotating shaft 2 is rotatably disposed in the cylindrical through hole 31 of the rotating member 3, realizing the rotation between the rotating member 3 and the fixed member 1. A notch 32 is provided on the inner wall of the cylindrical through hole 31. The connecting member 4 is connected to the portion of the rotating shaft 2 located in the notch 32. The rotating member 3 rotates relative to the fixed member 1 towards both sides until it abuts against the inner wall of the notch 32. At this point, the rotating member 3 has reached its limit position. In this embodiment, the structure of the rotating member 3 and the notch 32 on the cylindrical through hole 31 limits the rotation trajectory of the rotating member 3. After the connecting member 4 is connected to the rotating shaft 2, when the rotating member 3 rotates relative to the fixed member 1, the rotating member 3 also rotates relative to the connecting member 4. At this time, any connecting part can rotate to the connecting member 4 and detachably connect to the other end of the connecting member 4, thereby realizing the detachable connection between the rotating member 3 and the connecting member 4, that is, realizing the angular positioning between the rotating member 3 and the fixed member 1. When different connecting parts on the connector 4 are connected to the rotating part 3, the angles between the fixing part 1 and the rotating part 3 are also different, thereby realizing the adjustment of the connection angle between the rotating part 3 and the fixing part 1.

[0042] Preferably, in another embodiment of the present invention, the end of the rotating member 3 connected to the connecting member 4 and the end of the rotating shaft 2 located in the cylindrical through hole 31 are flush with each other.

[0043] In this embodiment, such as Figure 3 As shown, the rotating part 3 and the rotating shaft 2 are flush, and when the connecting part 4 is connected to both, it fits against both, thereby improving the stability of the connection between the connecting part 4 and the rotating part 3 and the rotating shaft 2.

[0044] Preferably, in another embodiment of this utility model, the rotating shaft 2 has at least two first positioning holes 21 arranged circumferentially on one end of the cylindrical through hole 31. One end of the connecting member 4 has a first through hole 41 corresponding to the number of the first positioning holes 21. The first positioning holes 21 are connected to the corresponding first through holes 41, and a first shaft pin is inserted to connect and fix the connecting member 4 to the rotating shaft 2. The rotating member 3 has a plurality of second positioning holes 33 evenly distributed circumferentially on the cylindrical through hole 31. The other end of the connecting member 4 has a second through hole 42. When the rotating member 3 rotates around the rotating shaft 2, the second through hole 42 can rotate to communicate with any of the second positioning holes 33, and a second shaft pin is inserted to connect and fix the connecting member 4 to the rotating member 3. When the rotating member 3 rotates around the rotating shaft 2, and the second through hole 42 communicates with the two second positioning holes 33 located at the edge, the connecting member 4 abuts against the inner wall of the notch 32.

[0045] In this embodiment, such as Figure 3 As shown, the connector 4 and the rotating shaft 2 are connected by a first axle pin (not shown in the attached figure). The connection position between the connector 4 and the rotating shaft 2 is fixed. When the different second positioning holes 33 are rotated to communicate with the second through hole 42, the second pin is inserted to fix the connector 4 and the rotating part 3. Thus, the angle between the rotating part 3 and the fixed part 1 can be adjusted as needed to select the corresponding second positioning hole 33. The second positioning hole 33 constitutes the connecting part of the rotating part 3.

[0046] Preferably, in another embodiment of the present invention, the rotating member 3 is provided with a plurality of grooves 34 evenly distributed along the circumference of the cylindrical through hole 31, and the other end of the connecting member 4 is provided with a plurality of protrusions 43 corresponding to the grooves 34.

[0047] In this embodiment, such as Figure 3 As shown, multiple grooves 34 are evenly distributed along the circumference of the cylindrical through hole 31 on the rotating component 3, such as... Figure 8As shown, multiple protrusions 43 are evenly distributed along the circumference of the shaft 2 at the other end of the connector 4. Since the shaft 2 and the cylindrical through hole 31 are coaxial, multiple grooves 34 and multiple protrusions 43 can be arranged on the same circumference. Moreover, the distance between two adjacent protrusions 43 is equal to the distance between two adjacent grooves 34, so that no matter which connection part of the connector 4 is connected to the rotating part 3, at least one protrusion 43 can be embedded in a groove 34, thereby stabilizing the connection between the connector 4 and the rotating part 3.

[0048] Preferably, as another embodiment of this utility model, such as Figure 2 , Figure 5 and Figure 6 As shown, the fixing component 1 has a first channel 11, the rotating shaft 2 has a second channel 22, and the rotating component 3 has a third channel 35. The second channel 22 is connected to the first channel 11 and the third channel 35 respectively, forming a wiring channel.

[0049] In this embodiment, by setting up a wiring channel, when the voiceprint detector 6 is fixed on the inspection robot by the angle adjustment structure of this embodiment, the connection harness between the inspection robot and the voiceprint detector 6 is set in the wiring channel, and the connection harness is protected by the wiring channel.

[0050] Preferably, in another embodiment of the present invention, the other end of the rotating member 3 is provided with a flange 36.

[0051] In this embodiment, the other end of the rotating component 3 is provided with a flange 36. For example... Figure 8 As shown, when the voiceprint detector 6 is fixed on the inspection robot by the angle adjustment structure of this embodiment, the rotating part 3 is connected to the voiceprint detector 6 through the flange 36.

[0052] Preferably, as another embodiment of the present invention, it further includes:

[0053] Mounting block 5 is disposed on the fixing member 1. The mounting block 5 is hollow inside and communicates with the first channel 11.

[0054] like Figure 9 As shown, an embodiment of the present invention also provides a voiceprint detection device, including a voiceprint detector 6 and an angle adjustment structure as described in any of the above claims, wherein the rotating member 3 is connected to the voiceprint detector 6.

[0055] In this embodiment, when the voiceprint detector 6 is fixed to the inspection robot using the angle adjustment structure, the fixing member 1 is fixed to the inspection robot, and the rotating member 3 is connected to the voiceprint detector 6. The angle of the voiceprint detector 6 is adjusted by adjusting the angle between the rotating member 3 and the fixing member 1. The connecting harness between the inspection robot and the voiceprint detector 6 is located in the wiring channel.
