Technical Field

[0001] This utility model relates to the field of voiceprint detection, and more specifically, to a voiceprint detection device for switch cabinets. Background Technology

[0002] In the field of acoustic signature detection for switchgear, existing detection devices often suffer from limited acquisition range and insufficient adjustment precision: most devices are fixedly installed, making it impossible to flexibly adjust the detection direction and height, and thus difficult to cover acoustic signature characteristics of different areas within the switchgear; some adjustable devices rely on manual operation, resulting in low precision in steering and position control, which can easily lead to omissions or deviations in acoustic signature acquisition; at the same time, acoustic signal acquisition is easily affected by stray sound waves in the environment, reducing detection accuracy; in addition, some devices lack a position feedback mechanism, making it impossible to accurately record the acquisition point and affecting the traceability of the detection data. These problems restrict the comprehensiveness and reliability of acoustic signature detection, and there is an urgent need for a structural design that is flexibly adjustable, accurately positioned, and can enhance the acoustic signal acquisition effect. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a switch cabinet acoustic signature detection device, including a base plate for mounting and fixing with the switch cabinet. A vertically extending guide is provided above the base plate, and a detection component that moves along the extension direction of the guide is connected to the guide. A first servo motor is connected to the bottom end of the guide. The first servo motor drives the guide to rotate, causing the detection component to move back and forth along the direction of the guide. A horizontal steering component is provided at the bottom end of the first servo motor. The horizontal steering component is mounted on the base plate. The rotation of the horizontal steering component causes the first servo motor, the guide, and the detection component to rotate horizontally, adjusting the direction of the detection component inside the switch cabinet.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0017] like Figure 1-3 The switch cabinet acoustic signature detection device shown includes a base plate 1 for mounting and fixing with the switch cabinet. A vertically extending guide 2 is provided above the base plate 1. A detection component 3 that moves along the extension direction of the guide 2 is connected to the guide 2. A first servo motor 4 is connected to the bottom end of the guide 2. The first servo motor 4 drives the guide 2 to rotate, causing the detection component 3 to move back and forth along the direction of the guide 2. A horizontal steering component 5 is provided at the bottom end of the first servo motor 4. The horizontal steering component 5 is mounted on the base plate 1. The rotation of the horizontal steering component 5 causes the first servo motor 4, the guide 2 and the detection component 3 to rotate horizontally, adjusting the direction of the detection component 3 inside the switch cabinet.

[0018] Based on the above, the base plate 1 is fixed to the inner wall of the switch cabinet, providing a stable installation foundation for the entire device; the guide 2 serves as the moving track for the detection component 3, providing it with a vertical movement path; the first servo motor 4 drives the guide 2 to rotate, converting the rotational motion into linear reciprocating motion of the detection component 3 along the extension direction of the guide 2, thereby realizing the vertical position adjustment of the detection component 3; the horizontal steering component 5 rotates itself, driving the first servo motor 4, the guide 2, and the detection component 3 to rotate horizontally as a whole, thereby flexibly adjusting the horizontal orientation of the detection component 3 within the switch cabinet so that it can be aligned with different areas;

[0019] Furthermore, the base plate 1 provides stable fixation, and combined with the movement adjustment of the guide 2 and the direction adjustment of the horizontal steering component 5, the detection component 3 can cover more areas inside the switch cabinet, adapting to the voiceprint collection needs of different locations.

[0020] The horizontal steering component 5 includes a bearing ring 51 fixedly mounted on the base plate 1 and a connecting post 52 inserted into the bearing ring 51. A connecting plate 53 is mounted on the top of the connecting post 52, and the first servo motor 4 is fixed on the surface of the connecting plate 53.

[0021] Based on the above, the bearing ring 51 is fixed on the base plate 1 to provide rotational support for the connecting column 52. The connecting column 52 can rotate flexibly along the inner ring of the bearing ring 51. The connecting plate 53 is installed on the top of the connecting column 52 as a carrier to support the first servo motor 4. When the connecting column 52 rotates, the connecting plate 53 synchronously drives the first servo motor 4, the guide 2 and the detection component 3 to rotate, thereby realizing the horizontal steering adjustment.

[0022] The fit between the bearing ring 51 and the connecting column 52 reduces frictional resistance during rotation, ensuring smooth steering; the connecting plate 53 enhances the installation stability of the first servo motor 4, preventing wobbling during rotation.

[0023] A connecting tooth 54 is installed at the edge of the connecting plate 53, and a second servo motor 55 is installed on the base plate 1. A gear 56 that meshes with the connecting tooth 54 is installed at the end of the output shaft of the second servo motor 55.

[0024] Based on the above, when the second servo motor 55 is working, its output shaft drives the gear 56 to rotate. The gear 56 meshes with the connecting teeth 54 on the edge of the connecting disk 53, transmitting the rotational motion of the gear 56 to the connecting disk 53, thereby driving the connecting column 52 to rotate along the bearing ring 51, ultimately realizing the horizontal steering of the first servo motor 4, the guide 2, and the detection component 3; through the precise control of the second servo motor 55, the steering angle can be precisely adjusted.

[0025] The meshing transmission between gear 56 and connecting teeth 54, combined with the precise drive of the servo motor, enables the detection component 3 to rotate precisely in the horizontal direction, ensuring the accuracy of the voiceprint acquisition angle.

[0026] The guide member 2 includes a support rod 21 vertically mounted on the surface of the connecting plate 53 and a positioning plate 22 fixed to the top of the support rod 21. The positioning plate 22 is parallel to the surface of the connecting plate 53. A first bearing 23 is embedded in the positioning plate 22. The output shaft of the first servo motor 4 extends to the top of the positioning plate 22 through the first bearing 23. The output shaft of the first servo motor 4 above the positioning plate 22 is connected to an upwardly extending guide rod 24. A parallel limiting rod 25 is provided on one side of the guide rod 24. The end of the limiting rod 25 is fixed to the surface of the positioning plate 22.

[0027] Based on the above, the support rod 21 vertically connects the connecting plate 53 and the positioning plate 22 to form a stable frame structure, providing an installation base for the guide rod 24 and the limiting rod 25; the first bearing 23 is embedded in the positioning plate 22 to reduce the friction between the output shaft of the first servo motor 4 and the positioning plate 22 when the output shaft rotates, ensuring smooth rotation of the output shaft; the output shaft of the first servo motor 4 drives the guide rod 24 to rotate synchronously, and the guide rod 24 provides a vertical moving track for the detection component 3; the limiting rod 25 is parallel to the guide rod 24 and is used to limit the rotation of the detection component 3, ensuring that it moves only in the vertical direction;

[0028] Furthermore, the frame structure is stable, which improves the load-bearing capacity of the guide component 2; the first bearing 23 reduces component wear and extends service life; the limit rod 25 ensures the stability of the movement direction of the detection component 3 and avoids deviation.

[0029] The detection component 3 includes a first sleeve 31 sleeved outside the guide rod 24 and a manifold 32 installed on the outer wall of the first sleeve 31. The manifold 32 is horn-shaped and has an acoustic sensor 33 installed inside.

[0030] Based on the above, the acoustic sensor 33 adopts a high-sensitivity microphone structure, with its sensing surface facing the inside of the horn of the junction box 32. It can directly capture the acoustic signals inside the switch cabinet gathered by the junction box 32, such as conductor vibration sound, component movement sound, abnormal discharge sound, etc. The acoustic sensor 33 is connected to the external signal transmission interface through a wire, which is hidden inside the first sleeve 31. It converts the collected sound signal into an electrical signal and outputs it to the outside. The horn-shaped structure of the junction box 32 reduces the interference of stray sound waves in the surrounding environment through physical sound focusing, so that the acoustic sensor 33 can capture the acoustic features of the target area more accurately. In addition, the sensor shell is made of insulating material to avoid electrical interference with the junction box 32 or internal components of the switch cabinet.

[0031] Furthermore, the sound-focusing effect of the manifold 32 improves the sensitivity and accuracy of acoustic signature acquisition and reduces the influence of irrelevant noise; the acoustic sensor 33 moves with the detection component 3 and can acquire acoustic signature signals at different heights.

[0032] A second sleeve 34 is provided on one side of the first sleeve 31 and is sleeved outside the limiting rod 25. The inner wall of the first sleeve 31 and the outer wall of the guide rod 24 are provided with mutually matching threads. A detachable nut 35 is installed at the end of the guide rod 24 away from the positioning plate 22.

[0033] Based on the above, when the guide rod 24 rotates, its outer wall thread interacts with the inner wall thread of the first sleeve 31, converting the rotational motion of the guide rod 24 into the axial movement of the first sleeve 31; the second sleeve 34 is fitted on the limiting rod 25 and moves synchronously with the first sleeve 31, restricting the rotation of the first sleeve 31 with the guide rod 24 and ensuring that it moves smoothly only in the vertical direction; the nut 35 is installed at the end of the guide rod 24 to prevent the first sleeve 31 from detaching from the guide rod 24 when it moves, thus ensuring structural safety.

[0034] The threaded drive enables high precision in adjusting the vertical position of the detection component 3, and with the guidance of the limit rod 25, the movement is smooth and without shaking; the nut 35 enhances the safety of the device and prevents components from falling off.

[0035] A plug plate 36 is connected between the first sleeve 31 and the second sleeve 34, and a distance sensor 37 facing the positioning plate 22 is installed on the plug plate 36.

[0036] Based on the above, the insert plate 36 is fixedly connected to the first sleeve 31 and the second sleeve 34, and moves synchronously with the detection component 3; the distance sensor 37 faces the positioning plate 22, detects the distance between the insert plate 36 and the positioning plate 22 in real time, and then accurately feeds back the current vertical position of the detection component 3, providing a position reference for the control of the first servo motor 4, and ensuring that the detection component 3 can accurately stop at the preset height.

[0037] The distance sensor 37 enables real-time monitoring and feedback of the position of the detection component 3, improving the accuracy of position adjustment and ensuring the controllability and consistency of the voiceprint acquisition position.
