Description

Technical Field

[0001] This utility model relates to the field of sound acquisition technology, and in particular to a sound acquisition device that is easy to install. Background Technology

[0002] Sound acquisition devices (with a microphone or pickup at their core) are transducers that convert sound waves into electrical signals. Their core principle is to utilize the vibration of sound waves acting on a diaphragm, and then generate corresponding electrical signals through physical mechanisms such as electromagnetic induction (moving coil type), capacitance change (capacitive type, requiring power supply), or piezoelectric effect. Sound acquisition devices used for monitoring utilize the sound waves or vibrations transmitted by the monitored equipment for non-invasive or minimal-invasive monitoring. Like a "stethoscope," it captures unique acoustic signals generated by fluid flow, equipment operation, and abnormal events (such as leaks, valve malfunctions, pump cavitation, and structural crack propagation) through direct contact (such as tight coupling with piezoelectric sensors) or non-contact methods (such as airborne acoustic sensors). After amplification, filtering, and digital acquisition, these signals undergo in-depth processing through time-domain and frequency-domain analysis and intelligent algorithms (such as pattern recognition) to achieve accurate leak location (often using time-of-flight positioning methods), equipment condition diagnosis, and early fault warning. Its core advantages lie in real-time monitoring, early problem detection, long-distance coverage, and rich diagnostic information, and it is widely used in many industries such as oil and gas, urban water and heating supply, chemical industry, and power.

[0003] Existing sound acquisition equipment connects to a mounting plate and a base. The mounting plate has mounting holes, which can be bolted through to fix the plate to a flat surface or wall, thus securing the sound acquisition equipment. However, when it is necessary to fix the sound acquisition equipment to cylindrical rods or pipes of different thicknesses and shapes, it is necessary to replace it with a non-planar mounting plate of a different shape. The replacement and installation process is time-consuming and inconvenient. Utility Model Content

[0008] Furthermore, a second gripper is rotatably connected to the outer wall of the first gripper, and the inner walls of the first gripper and the second gripper are rotatably connected via a rotating rod. An adjusting bolt is threadedly connected to the inner wall of the first gripper, and the outer wall of the adjusting bolt stud is threadedly connected to the inside of the second gripper.

[0014] 1. In this utility model, when installing the sound acquisition device on a flat surface or wall, the clamping mechanism is disassembled, and then bolts are used to complete the installation through the mounting holes on the first fixing plate. When installing the sound acquisition device on a cylindrical rod or pipe, the adjusting bolt is rotated, and the clamping jaws complete the clamping. For different specifications, the ball pin can also be removed and different specifications of clamping jaws can be replaced. The addition of the clamping mechanism simplifies the installation of the sound acquisition device on cylindrical rods or pipes, making installation simple and convenient.

A first fixing plate 1 is fixedly connected to the lower surface of the base 3. The first fixing plate 1 has four mounting holes 2 at its four corners. When the sound acquisition device is installed on a flat surface or wall, it is installed by bolts passing through the mounting holes 2. A clamping mechanism is provided at the bottom of the first fixing plate 1. The clamping mechanism includes a first gripper 15, which is located at the bottom of the first fixing plate 1. A second ball joint 14 is fixedly connected to the upper surface of the first gripper 15. A second gripper 16 is rotatably connected to the outer wall of the first gripper 15. The first jaw 15 and the second jaw 16 are rotatably connected via a rotating rod 18. The second jaw 16 and the first jaw 15 can open. An adjusting bolt 17 is threaded onto the inner wall of the first jaw 15. The outer wall of the adjusting bolt 17 is threaded onto the inside of the second jaw 16. Rotating the adjusting bolt 17 allows for precise control of the opening or closing of the first jaw 15 and the second jaw 16. When the sound acquisition device is installed on a cylindrical rod or pipe, rotating the adjusting bolt 17 can easily achieve this. The spherical outer wall of the second ball joint 14 is rotatably connected to a right hemispherical pin 9. The jaws can rotate through the second ball joint 14 and the ball pin. The inner wall of the right hemispherical pin 9 is rotatably connected to the first... The ball joint 8 allows the ball pin to rotate. The spherical outer wall of the second ball joint 14 is rotatably connected to the left hemispherical pin 10. The inner surface of the left hemispherical pin 10 has a third fixing hole 12, which is a threaded hole. The right hemispherical pin 9 has a second fixing hole 11, which is a smooth hole. A fixing bolt 13 is rotatably connected to the inner wall of the right hemispherical pin 9. One end of the fixing bolt 13 is threaded into the inner wall of the third fixing hole 12. For cylindrical rods or pipes of different specifications, the ball pin can be disassembled using the fixing bolt 13 to replace different specifications of clamps. The inner wall of the left hemispherical pin 10 is rotatably connected to the first ball joint 8. The spherical outer wall of joint 8 allows the orientation of the sound acquisition device to be adjusted via the first ball joint 8 and the second ball joint 14. A second fixing plate 6 is fixedly connected to the upper surface of the first ball joint 8. The second fixing plate 6 has four first fixing holes 7 inside. The upper surface of the second fixing plate 6 is fixedly connected to the lower surface of the first fixing plate 1 by bolts. When the sound acquisition device is installed on a plane or wall, the first fixing plate 1 and the second fixing plate 6 can be disassembled through the four first fixing holes 7, thereby disassembling the clamping mechanism. The clamping mechanism simplifies the installation of the sound acquisition device on cylindrical rods or pipes, making installation simple and convenient. A storage mechanism is provided above the base 3.

[0025] Reference Figures 3-5The storage mechanism includes a storage cavity 4, inside which a sound acquisition component is installed. The storage cavity 4 can store the sound acquisition component. The lower surface of the storage cavity 4 is rotatably connected to the upper surface of the base 3. Four guide protrusions 23 are fixedly connected to the inner wall of the storage cavity 4. A screw 25 is fixedly connected to the top of the base 3. A rotation hole 24 is opened at the bottom of the storage cavity 4. The bottom of the screw 25 is rotatably connected to the inner surface of the rotation hole 24. The bottom structure of the screw 25 will allow the storage cavity 4 to rotate only on the base 3. The outer walls of the four guide protrusions 23 are slidably connected to the outer wall of the sound acquisition device 19. Under the action of the guide protrusions 23, the sound acquisition device 19 can only move up and down within the storage cavity 4, or rotate with the storage cavity 4. The outer wall of the screw 25 is threadedly connected to the inner wall of the sound acquisition device 19. The outer wall of the screw 25 is also threadedly connected to the pre-set screw hole 22 inside the sound acquisition device 19.

[0026] Reference Figures 1-4 The sound acquisition component includes a sound collector 19, whose outer wall is slidably connected to the inner wall of the storage cavity 4. A screw hole 22 is provided at the bottom of the sound collector 19, and four guide grooves 21 are provided on the outer wall of the sound collector 19. A collection cover 20 is fixedly connected to the upper surface of the sound collector 19. The collection cover 20 collects and transmits sound to the sound collector 19, converting it into an electrical signal for storage. A dust cover 5 is slidably connected to the outer wall of the storage cavity 4. The dust cover 5 can be removed from the storage cavity 4. Rotating the storage cavity 4 causes the sound collector 19 to rotate. Under the action of the screw hole 22 and the screw 25, the sound collector 19 and the collection cover 20 gradually rise or fall with the rotation of the storage cavity 4, storing the sound acquisition component inside the storage cavity 4. Covering it with the dust cover 5 prevents dust from entering the sound acquisition device, improving the cleanliness and service life of the sound acquisition device.

[0027] Working principle: When installing the sound acquisition device on a flat surface or wall, remove the bolts inside the first fixing hole 7 to separate the second fixing plate 6 from the first fixing plate 1, thus disassembling the clamping mechanism. Then, use bolts to complete the installation on the flat surface or wall through the mounting holes 2 on the first fixing plate 1. When installing the sound acquisition device on a cylindrical rod or pipe, rotate the adjusting bolt 17. The first clamp 15 and the second clamp 16, fixed by the rotating rod 18, can open or close. The clamping mechanism is held onto the cylindrical rod or pipe by the first clamp 15 and the second clamp 16. The ball pin 9 has a second fixing hole 11, and the left hemisphere pin 10 has a third fixing hole 12. The fixing bolt 13 fixes the right hemisphere pin 9 and the left hemisphere pin 10 through the second fixing hole 11 and the third fixing hole 12. The first gripper 15 can rotate within the right hemisphere pin 9 and the left hemisphere pin 10 through the second ball joint 14. When it is necessary to install the sound acquisition device on cylindrical rods or pipes of different thicknesses, the fixing bolt 13 can be removed and the gripper of different sizes can be replaced. When the sound acquisition device is in use, the right hemisphere pin 9 and the left hemisphere pin 10 are connected by the first ball joint 8 and the second fixing hole 12. The fixed plate 6 is connected to the first fixed plate 1. The first ball joint 8 and the second ball joint 14 can rotate inside the right hemisphere pin 9 and the left hemisphere pin 10 to adjust the facing direction of the sound acquisition device. Then, the dust cover 5 is removed from the storage cavity 4. The base 3 is fixed to the first fixed plate 1. The base 3 has a screw 25 in the middle. The bottom surface of the storage cavity 4 has a rotating hole 24. The bottom structure of the screw 25 allows the storage cavity 4 to rotate only on the base 3. The inner wall of the storage cavity 4 has four guide protrusions 23. The side of the sound acquisition device 19 has four guide grooves 21. The guide protrusions 23 and guide grooves 21 are used to... When in use, the sound collector 19 can only move up and down within the storage cavity 4, or rotate with the storage cavity 4. Above the sound collector 19 is a collection cover 20, which collects and transmits sound to the sound collector 19, converts it into an electrical signal, and stores it. The sound collector 19 is connected to the screw 25 through the screw hole 22 at the bottom. When the storage cavity 4 is rotated, the sound collector 19 rotates with the storage cavity 4. Under the action of the screw hole 22 and the screw 25, the sound collector 19 and the collection cover 20 gradually rise or fall with the rotation of the storage cavity 4, completing the preparation or storage of the sound collection device.
