Description

Technical Field

[0001] This application belongs to the field of acoustic acquisition technology, specifically relating to an acoustic array device for real-time data processing of fan acoustic signatures. Background Technology

[0002] Acoustic array devices for real-time wind turbine acoustic data processing typically refer to systems composed of multiple vibrating units (such as loudspeakers or microphones) arranged in a certain geometric shape and manner. These units can emit the same or different sound signals. By controlling the phase and amplitude of each unit, the shape and directionality of the sound beam can be adjusted. Multiple acoustic sensors (such as microphones) are used to collect sound signals from the wind turbine blades during operation. These sensors can be arranged in different parts of the wind turbine to collect comprehensive acoustic data.

[0003] Testing revealed that the existing acoustic array device for real-time data processing of wind turbine acoustic patterns has a problem in use. Since the acoustic array is composed of multiple microphones, some microphones may become damaged or have poor performance and need to be replaced during long-term use. However, the acoustic array is a whole, and it is difficult to quickly replace individual microphones, which affects the overall use of the acoustic array. Utility Model Content

[0052] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0053] See also Figure 1-8 As shown, according to an embodiment of this application, an acoustic array device for real-time data processing of wind turbine acoustic signatures is provided, comprising:

[0054] Mounting box 1, with an opening on it;

[0055] The first mounting plate 2 is disposed inside the mounting box 1, and the first mounting plate 2 has mounting holes arranged in an array.

[0056] The second mounting plate 3 is disposed inside the mounting box 1 and located on one side of the first mounting plate 2. A quick-release assembly is provided on the second mounting plate 3 at the location matching the mounting hole. The quick-release assembly includes a first limiting part 4.

[0057] The microphone 5 has a plug plate 6 installed on it. The plug plate 6 passes through the mounting hole and is installed in the first limiting part 4. The first limiting part 4 is used to fix the plug plate 6.

[0058] Specifically, the opening on one side of the mounting box 1 provides a convenient passage for the installation, debugging, and maintenance of internal components. Workers can easily operate the first mounting plate 2, the second mounting plate 3, and the microphone 5 through the opening, such as installing a new microphone 5 or replacing damaged parts. On the other hand, the opening also has a certain heat dissipation function, ensuring air circulation inside the mounting box 1 and preventing heat buildup from the microphone 5 during prolonged operation from affecting its performance.

[0059] The first mounting plate 2 is located inside the mounting box 1, and has mounting holes arranged in an array on it. The array distribution of the mounting holes allows multiple microphones 5 to be evenly distributed on the first mounting plate 2, thereby comprehensively and accurately collecting the sound signature data generated by the fan to achieve the best sound signature collection effect. The second mounting plate 3 is located on one side of the first mounting plate 2, and has quick-release components installed on it at the matching positions of the mounting holes. The first limiting part 4 in the quick-release component can cooperate with the plug plate 6 on the microphone 5 to firmly fix the plug plate 6, thereby fixing the microphone 5 after installation and facilitating the disassembly and replacement of the microphone 5.

[0060] By modularizing multiple microphones 5, the failure of a single microphone 5 will not affect the normal operation of the entire acoustic array. When a microphone 5 malfunctions, staff can quickly remove it using quick-release components and replace it with a new microphone 5 without requiring extensive overhaul of the entire device.

[0061] Among them, receiver 5 is a microphone.

[0062] The microphones 5 can be installed in a circular array or in a rectangular array on the first mounting plate 2, depending on the usage requirements, and there is no limitation here.

[0063] The first limiting part 4 includes:

[0064] The first connecting box 7 is disposed on the second mounting plate 3, and fixing boxes 8 are provided on both sides of the first connecting box 7;

[0065] Push block 9 is disposed in the first connecting box 7. A driving component 10 is disposed in the fixed box 8. The driving component 10 is connected to the push block 9 and is used to drive the push block 9 to move toward or away from the fixed box 8. A plug-in space for the installation of plug-in board 6 is provided between the push blocks 9.

[0066] Specifically, the first connecting box 7 is securely mounted on the second mounting plate 3, providing operating space for the internal push block 9. The fixing boxes 8 on both sides not only fix the drive component 10 but also protect it from external interference and damage. There are two drive components 10, installed in the fixing boxes 8 on both sides respectively. The push block 9 is mounted on the drive component 10, and the drive component 10 can move the push block 9 toward or away from the fixing box 8. During installation, the plug-in plate 6 is inserted between the push blocks 9. The drive component 10 will drive the push block 9 to clamp the inserted plug-in plate 6 from both sides, thereby fixing the installed radio 5. During disassembly, the plug-in plate 6 can be easily pulled out by pulling it outward.

[0067] Among them, the push block 9 has an inclined structure on the end facing the first mounting plate 2, and the plug end of the plug plate 6 has a wedge-shaped structure, which makes it easy to plug the plug plate 6 into the two push blocks 9, and facilitates the installation and removal of the radio 5.

[0068] The drive component 10 can be a small electric actuator, cylinder, or spring mechanism.

[0069] The drive unit 10 includes:

[0070] Support frame 11 is disposed in fixed box 8. Support frame 11 includes a first support surface and a second support surface perpendicularly disposed on the first support surface. Sliding holes are provided on the second support surface.

[0071] Mounting rod 12, which is symmetrically arranged on the first support surface;

[0072] Movable plate 13 is slidably mounted on mounting rod 12, and its top is slidably connected to sliding hole;

[0073] The first elastic element 14 is sleeved on the mounting rod 12 and is located between the first support surface and the movable plate 13.

[0074] Mounting post 15 is positioned between movable plate 13 and push block 9. In the natural state of the first elastic member 14, the distance between push blocks 9 is less than the width of plug plate 6.

[0075] Specifically, the support frame 11 is installed inside the fixed box 8. It includes a first support surface and a second support surface perpendicularly connected thereto. The first support surface and the second support surface are connected to form an L-shaped structure. The mounting rod 12 is vertically installed on the first support surface. A sliding hole is opened on the second support surface. The movable plate 13 is slidably installed on the mounting rod 12, and its top is slidably installed in the sliding hole. When the movable plate 13 slides on the mounting rod 12, the sliding connection between its top and the sliding hole can effectively restrict the movement direction of the movable plate 13, so that it can only move in a straight line along the direction of the sliding hole, thereby ensuring the stability and accuracy of the push block 9 during the movement process.

[0076] The first elastic element 14 is sleeved on the mounting rod 12 and located between the first support surface and the movable plate 13. It is used to realize the automatic reset of the push block 9. In its natural state, the distance between the push blocks 9 on both sides of the first elastic element 14 is less than the width of the plug plate 6. When the microphone 5 needs to be installed, the operator inserts the plug plate 6 between the two push blocks 9. At this time, the push blocks 9 will move into the fixing box 8, so that the first elastic element 14 is compressed and the distance between the push blocks 9 gradually increases until the plug plate 6 is fully inserted. Under the action of the elastic potential energy of the first elastic element 14, the push blocks 9 are pressed against both sides of the plug plate 6, thus achieving a firm fixation of the microphone 5.

[0077] There are two mounting columns 15, which are installed at intervals on the first support surface. The movable plate 13 is slidably installed on the mounting columns 15. By setting two mounting columns 15, the movable plate 13 can be better limited in the horizontal direction, thereby improving the stability of the push block 9 movement.

[0078] The first elastic element 14 is a spring, and the number of springs matches the number of mounting posts 15.

[0079] An indicator light 16 is provided on the first mounting plate 2 and on the side of the microphone 5. A pressure sensor 17 is provided on the side of the first connecting box 7 away from the first mounting plate 2. The indicator light 16 is electrically connected to the pressure sensor 17.

[0080] Specifically, indicator lights 16 are mounted on the first mounting plate 2 and located on one side of the microphone 5. Each microphone 5 has one indicator light 16, allowing staff to clearly observe the equipment during operation without interfering with its normal operation. The indicator lights 16 visually demonstrate the installation and operating status of the microphone 5. A pressure sensor 17 is located on the side of the first connecting box 7 away from the first mounting plate 2. When the connector plate 6 of the microphone 5 is inserted into the first limiting part 4, i.e., between the push blocks 9 inside the first connecting box 7, and is properly installed, the connector plate 6 applies pressure to the push blocks 9. Since the indicator lights 16 and pressure sensor 17 are electrically connected, when the pressure sensor 17 detects that the pressure has reached the set pressure range due to the insertion of the connector plate 6, it immediately transmits the corresponding electrical signal to the indicator lights 16. At this time, the indicator lights 16 will display a specific state based on the received signal. For example, when the pressure sensor 17 detects the set pressure value, indicating that the microphone 5 has been correctly installed and secured, the indicator lights 16 will turn off, visually conveying the information of successful installation to the staff. This greatly improves the convenience of the installation process. Staff no longer need to go through complex inspection steps to confirm whether the microphone 5 is installed correctly; they can quickly determine this simply by observing the status of indicator light 16. Conversely, if the microphone 5 is not installed or is improperly installed, such as when the connector 6 is not inserted or not fully inserted, causing the pressure sensor 17 to fail to detect a pressure value, indicator light 16 will illuminate red or flash, reminding staff that there is a problem with the installation of the microphone 5 and that it needs to be readjusted. This real-time feedback mechanism also plays an important role in the daily maintenance of the device. During device operation, if a microphone 5 becomes loose due to vibration, external force, or other reasons, the pressure change detected by pressure sensor 17 will trigger a change in the status of indicator light 16 again, promptly informing staff that the corresponding microphone 5 needs to be tightened or inspected, preventing the accuracy of voiceprint data acquisition from being affected by a loose microphone 5.

[0081] The quick-release assembly also includes a second limiting part 18, which includes:

[0082] The second connecting box 19 is disposed on the second mounting plate 3 and located on one side of the first connecting box 7. A limit groove is provided on the second connecting box 19.

[0083] Magnetic suction component 20 is disposed within the limiting groove;

[0084] Positioning block 21 is set on plug plate 6. After plug plate 6 is installed in first connection box 7, positioning block 21 is magnetically connected to magnetic suction component 20 through limiting groove.

[0085] Specifically, the second connecting box 19 is mounted on the second mounting plate 3 and located on one side of the first connecting box 7. The limiting groove on the second connecting box 19 not only provides precise guidance for the insertion of the positioning block 21, but also limits the movement range of the positioning block 21 to a certain extent, ensuring that the positioning block 21 and the magnetic suction component 20 can be accurately aligned. The magnetic suction component 20 is set in the limiting groove. The suction component usually uses high-performance permanent magnet materials, such as neodymium iron boron magnets, which have strong magnetism and stability. This strong magnetism can quickly generate a strong magnetic attraction force with the positioning block 21 after the positioning block 21 is inserted into the limiting groove, firmly attracting the positioning block 21 into the limiting groove. The cooperation between the magnetic suction component 20 and the positioning block 21 ensures that the microphone 5 will not easily loosen under external vibration, impact, etc., and also allows for quick disassembly by applying a certain external force to overcome the magnetic attraction force when the microphone 5 needs to be disassembled.

[0086] The positioning block 21 is generally made of a metal material with good magnetic permeability, such as iron or nickel alloy, to enhance the magnetic attraction between it and the magnetic attractor 20. During installation, even if there is a certain deviation in the initial alignment between the positioning block 21 and the limiting groove, the magnetic force of the magnetic attractor 20 will guide the positioning block 21 to automatically adjust its position until it is accurately attracted to the magnetic attractor 20, ensuring the accuracy and reliability of the installation.

[0087] It also includes an information processing unit 22, which is mounted on the first mounting plate 2 and is electrically connected to the microphone 5, the pressure sensor 17 and the indicator light 16.

[0088] Specifically, the information processing unit 22 is mounted on the first mounting plate 2. Its electrical connection with the microphone 5 enables the voiceprint data to be transmitted quickly and stably to the information processing unit 22. After the microphone 5 converts the collected wind turbine voiceprint signal into an electrical signal, it transmits it to the information processing unit 22 through a dedicated data transmission line. The information processing unit 22 is equipped with an advanced digital signal processing chip and complex algorithm programs, which can efficiently analyze these raw voiceprint data. It can accurately extract and compare the frequency, amplitude, phase, and other features of the voiceprint, and quickly determine the operating status of the wind turbine by comparing it with a pre-stored database of normal wind turbine operation voiceprints. For example, when the wind turbine experiences abnormal conditions such as blade wear or bearing failure, its voiceprint characteristics will change significantly. The information processing unit 22 can keenly detect these changes and issue early warning signals in a timely manner.

[0089] The information processing unit 22 is electrically connected to the pressure sensor 17. The pressure sensor 17 monitors the pressure of the first limit part 4 on the plug plate 6 in real time and converts the pressure data into an electrical signal, which is then transmitted to the information processing unit 22. Based on this pressure data, the information processing unit 22 can monitor the installation status of the microphone 5 in real time. If the pressure data exceeds the normal range, it may mean that the microphone 5 is loose or improperly installed, and the information processing unit 22 will take corresponding measures immediately. On the one hand, it can send a command to the indicator light 16 to change the display status of the indicator light 16 to remind the staff; on the other hand, the information processing unit 22 can also record these abnormal data and generate a detailed equipment maintenance log, providing a strong basis for subsequent equipment inspection and maintenance.

[0090] It also includes a protective component, which is disposed on the opening of the mounting box 1. The protective component includes:

[0091] Filter screen 23 is hinged to the opening of the mounting box 1;

[0092] The snap-fit ​​part 24 is disposed between the filter screen 23 and the mounting box 1.

[0093] Specifically, the bottom of the filter 23 is hinged to the opening of the mounting box 1, facilitating its flexible opening and closing. The filter 23 is typically made of corrosion-resistant, high-strength metal or special synthetic materials. It effectively blocks external dust and debris from entering the mounting box 1, preventing damage to components such as the microphone 5 and information processing unit 22, thus ensuring normal operation. Simultaneously, it guarantees sufficient ventilation, allowing heat to dissipate from the mounting box 1 and maintaining a suitable operating temperature for the internal components. For example, in industrial production environments, the air often contains a large amount of dust particles. If this dust enters the device, it may accumulate on the microphone surface of the microphone 5, affecting the sensitivity of sound acquisition and even causing poor heat dissipation in the information processing unit 22, leading to malfunctions. The filter 23 effectively traps this dust, ensuring stable operation of the device. When maintenance, repair, or installation of a new microphone 5 is required for the internal components of the mounting box 1, operators can easily open the filter 23 via the hinge, facilitating operation without disrupting normal workflow.

[0094] The snap-fit ​​part 24 is disposed between the filter screen 23 and the mounting box 1. The snap-fit ​​part 24 can be a snap-fit ​​type, a magnetic type, or a bolt fastening type. The snap-fit ​​part 24 ensures that the filter screen 23 can fit tightly against the opening of the mounting box 1 when closed, effectively preventing foreign objects from entering, while allowing for convenient and quick operation when it needs to be opened.

[0095] The snap-fit ​​part 24 includes:

[0096] Support plate 25 is disposed on the top of mounting box 1, and the first end of support plate 25 is rotatably connected to mounting box 1;

[0097] The second elastic element 26 is disposed between the second ends of the support plate 25, and a snap-fit ​​block 27 is provided on the side of the support plate 25 away from the second elastic element 26.

[0098] The support frame 28 is disposed on the filter screen 23. In the natural state of the second elastic member 26, the snap-fit ​​block 27 is located inside the support frame 28.

[0099] Specifically, the support plate 25 is installed on the top of the mounting box 1, with its first end rotatably connected to the mounting box 1. When it is necessary to open the filter screen 23, the operator can rotate the support plate 25 to change its position, thereby releasing the restriction on the filter screen 23. The second elastic element 26 is disposed between the second ends of the support plate 25, and it is usually a spring with good elasticity and toughness. In its natural state, the second elastic element 26 applies a certain force to the support plate 25, keeping the support plate 25 in a specific position and state. This elastic force not only ensures a tight fit between the locking block 27 and the support frame 28, but also buffers external impact forces to a certain extent, reducing damage to the locking part 24 caused by vibration or collision.

[0100] The snap-fit ​​block 27 is located on the side of the support plate 25 away from the second elastic element 26, and its shape and size precisely match the support frame 28. When the filter screen 23 is closed, under the action of the second elastic element 26, the snap-fit ​​block 27 will accurately embed into the support frame 28, forming a firm snap-fit ​​effect. This ensures that the filter screen 23 will not easily open during normal use, and also allows the snap-fit ​​block 27 to be disengaged from the support frame 28 through a reasonable operation when it is necessary to open the filter screen 23.

[0101] In use, when it is necessary to open the filter screen 23, the operator only needs to apply an appropriate external force to the support plate 25 to overcome the elastic force of the second elastic element 26, causing the support plate 25 to rotate around its rotational connection point with the mounting box 1, thereby driving the locking block 27 to disengage from the support frame 28. At this time, the filter screen 23 can be easily opened through its hinged joint with the mounting box 1, facilitating maintenance and repair of the device's interior. After maintenance is completed, the filter screen 23 is closed, and the second elastic element 26 returns to its natural state, pushing the locking block 27 back into the support frame 28, thus securing the filter screen 23.

[0102] It also includes a support box 29, and the mounting box 1 is set inside the support box 29.

[0103] Support box 29 includes:

[0104] A base plate 30, on which fixed legs 31 are symmetrically arranged;

[0105] Box 32, box 32 is set on base plate 30, fixed leg 31 is located inside box 32, and mounting box 1 is rotatably set on fixed leg 31;

[0106] The driver 33 has its first end mounted on the base plate 30 and its second end mounted on the mounting box 1.

[0107] Specifically, the housing 32, mounted on the base plate 30, not only provides a relatively enclosed installation space for the mounting box 1 but also offers some protection. The housing 32 prevents accidental collisions with external objects, avoiding damage to internal components such as the microphone 5 and information processing unit 22. Simultaneously, the housing 32 also helps to block dust and moisture from corroding the mounting box 1, extending its lifespan. The base plate 30 has symmetrically arranged fixing legs 31, evenly distributed across it. The mounting box 1 rotates and is mounted on these legs, allowing operators to adjust the orientation of the acoustic array device according to actual needs for better reception of acoustic signals emitted by the fan. For example, in complex industrial plant environments, the location and layout of the fan may be complex; rotating the mounting box 1 allows the microphone 5 to be more precisely aligned with the fan, improving the accuracy and efficiency of acoustic data acquisition.

[0108] The first end of the driver 33 is mounted on the base plate 30, and the second end is mounted on the mounting box 1. The driver 33 can be an electric actuator, a hydraulic drive, or other devices with power output. When the angle of the mounting box 1 needs to be adjusted, the operator only needs to start the driver 33, which will output the corresponding power according to the set program or the operator's instructions. Taking the electric actuator as an example, when it receives a control signal, the motor inside the electric actuator drives the screw to rotate, causing the actuator to extend or retract, thereby driving the mounting box 1 to rotate around the fixed leg 31. By precisely controlling the power output of the driver 33, the rotation angle of the mounting box 1 can be accurately adjusted to meet the orientation requirements of the acoustic array device in different working scenarios. This automated adjustment method not only improves the convenience of operation, but also allows for quick and accurate angle adjustment when frequent adjustments to the device orientation are required, greatly improving work efficiency.
