Description

Technical Field

[0001] This disclosure specifically discloses a field of acoustic detection equipment technology, specifically relating to an array-type acoustic probe device for identifying equipment noise sources. Background Technology

[0002] The scientific definition of noise is noise. From a physiological point of view, any sound that interferes with people's rest, study and work, or interferes with the sounds that people want to hear, i.e. unwanted sounds, is collectively called noise. When noise has an adverse effect on people and the surrounding environment, it constitutes noise pollution.

[0003] According to application number 202420756057.3, a multi-directional acoustic probe for noise detection is disclosed, relating to the field of noise detection technology. It includes: an electric turntable; a sliding support structure is mounted on the outside of the electric turntable; a first noise-capturing structure and a second noise-capturing structure are mounted on the upper wall of the sliding support structure; a vibration-collecting structure is mounted on the upper wall of the electric turntable; and a support structure is mounted on the lower wall of the electric turntable. The sliding support structure includes: a sliding rod, a first sliding sleeve, and a second sliding sleeve. The sliding rod is mounted on the outside of the electric turntable, and the first sliding sleeve is movably fitted onto the outside of the sliding rod, with the sliding rod and the first sliding sleeve fixed together by bolts. This invention, through reciprocating detection of noise from multiple angles, can accurately determine the noise direction source, achieving accurate noise direction through a low-cost detection method.

[0004] Existing probe devices cannot be raised or lowered to detect noise from equipment at heights, and their length cannot be adjusted, making it impossible to detect noise inside the equipment or determine the location of equipment damage, thus reducing work efficiency. To address this, we propose an array-type acoustic probe device for identifying equipment noise sources. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a structure whose height and length are both expandable.

[0006] An array-type acoustic probe device for identifying equipment noise sources includes a base plate. A fixed box is fixedly connected to the middle of the upper surface of the base plate. A lifting device is provided on the bottom surface of the inner cavity of the fixed box. The upper part of the lifting device extends through to the upper part of the fixed box. A fixed sleeve is fixedly connected to the upper part of the lifting device. A stepper motor is fixedly connected to the bottom surface of the inner cavity of the fixed sleeve.

The end of the lead screw is movably connected to the top end face of the inner cavity of the fixed box. The moving plate is sleeved on the outer wall of the middle part of the lead screw. Limiting ports are opened on both the left and right sides of the top end face of the fixed box. The upper end face of the moving plate is fixedly connected to the connecting column on both the left and right sides. The end of the connecting column extends through the limiting port to the upper part of the fixed box. A fixed sleeve is fixedly connected to the upper end face of the connecting column.

[0009] According to the technical solution provided in the embodiments of this application, the detection device includes a connecting frame, a vibrating diaphragm, a sound sensor, a telescopic column, and a cylinder. The cylinder is fixedly connected to one end face of the fixed frame near the rotating disk. The extended end of the cylinder is fixedly connected to the telescopic column. The end of the telescopic column passes through both end faces of the fixed frame and is fixedly connected to the connecting frame. The vibrating diaphragm is fixedly connected to the outside of the connecting frame. The sound sensor is fixedly connected to one end face of the connecting frame near the rotating disk.

[0012] In summary, this application discloses an array-type acoustic probe device for identifying equipment noise sources.

[0013] Beneficial effects

[0014] The servo motor is started by using a fixed box and lifting device. The servo motor drives the lead screw to rotate. The lead screw is limited by the limit port and the connecting column. The lead screw drives the moving plate to rise and fall, thereby driving the connecting column to rise and fall. The connecting column drives the probe device to rise to the detection height.

[0015] The system consists of a fixed frame, a detection device, and a display screen. Starting the stepper motor rotates the rotating disk, which in turn rotates the fixed frame. Adjusting the direction of the probe device activates the cylinder, which in turn extends and retracts the telescopic column. The vibrating diaphragm receives the sound. The sound sensor is electrically connected to the display screen, ensuring that the screen can display the sound intensity and also study the sound waveform, facilitating analysis by staff.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] As mentioned in the background section, existing probe devices cannot be raised or lowered to detect noise from equipment at heights, and their length cannot be adjusted, making it impossible to detect internal noise, determine the location of equipment damage, and reduce work efficiency. This disclosure proposes a structure that is both height and length extendable.

[0024] Example 1

[0025] Please see Figure 1An array-type acoustic probe device for identifying equipment noise sources includes a base plate 1. A fixed box 2 is fixedly connected to the middle of the upper surface of the base plate 1. The fixed box 2 is rectangular and hollow. In order to ensure that the upper probe device can be raised and lowered, a lifting device 3 is provided on the bottom surface of the inner cavity of the fixed box 2. The upper part of the lifting device 3 extends through to the upper part of the fixed box 2. A fixed sleeve 6 is fixedly connected to the upper part of the lifting device 3 to effectively ensure the stability of the upper connecting column 31 of the lifting device 3.

[0026] Please see Figure 1 To facilitate the upper probe device to perform detection in different directions, a stepper motor 7 is fixedly connected to the bottom end face of the inner cavity of the fixed sleeve 6, and the motor shaft of the stepper motor 7 extends through to the upper end face of the fixed sleeve 6 and is fixedly connected to a rotating disk 8. The rotating disk 8 is easy to connect, and a fixed frame 10 is fixedly connected to both the left and right sides of the outer wall of the rotating disk 8. To facilitate the detection of the inside of the equipment, a detection device 9 is set inside the fixed frame 10, and the end of the detection device 9 extends through to both sides of the left and right fixed frames 10.

[0027] Please see Figure 3 To detect noise sources from devices at different heights, a lifting device 3 is constructed using a connecting column 31, a limiting port 32, a lead screw 33, a moving plate 34, and a servo motor 35. A servo motor 35 is fixedly connected to the bottom end face of the inner cavity of the fixed box 2. A lead screw 33 is fixedly connected to the motor shaft of the servo motor 35, and the end of the lead screw 33 is movably connected to the top end face of the inner cavity of the fixed box 2. A moving plate 34 is sleeved on the outer wall of the middle part of the lead screw 33. To allow the connecting column 31 to penetrate and lift through the top end face of the fixed box 2, limiting ports 32 are provided on both the left and right sides of the top end face of the fixed box 2. Connecting columns 31 are fixedly connected to both the left and right sides of the upper end face of the moving plate 34, and the ends of the connecting columns 31 extend through the limiting ports 32 to the upper part of the fixed box 2. The limiting ports 32 match the connecting columns 31, and the limiting ports 32 have a limiting function, ensuring that the rotation of the lead screw 33 will not cause the moving plate 34 to rotate.

[0028] Please see Figure 2 In order to dissipate heat from the servo motor 35, heat dissipation vents 4 are provided on the lower part of the left and right end faces of the fixed box 2. In order to prevent dust from entering the interior of the fixed box 2, dustproof mesh is fixedly connected to the heat dissipation vents 4 to prevent dust from entering the interior of the fixed box 2 and causing the heat of the servo motor 35 to be unable to dissipate.

[0029] Please see Figure 2In order to detect the source of noise generated by internal parts of the equipment, an elongation detection device is required. The detection device 9 is composed of a connecting frame 91, a vibrating diaphragm 92, a sound sensor 93, a telescopic column 94, and a cylinder 95. The cylinder 95 is fixedly connected to the inner cavity of the fixed frame 10 near the end face of the rotating disk 8. The telescopic column 94 is fixedly connected to the extended end of the cylinder 95. The end of the telescopic column 94 passes through both ends of the fixed frame 10 and is fixedly connected to the connecting frame 91. The vibrating diaphragm 92 is fixedly connected to the outside of the connecting frame 91. In order to clearly receive noise, a sound sensor 93 is fixedly connected to the end face of the connecting frame 91 near the rotating disk 8.

[0030] Please see Figure 2 In order to receive distant sounds and expand the receiving range, the diaphragm 92 is horn-shaped. A display screen 5 is fixedly connected to the center of the front end of the fixed box 2. The display screen 5 is electrically connected to the sound sensor 93 to ensure that the display screen 5 can display the sound intensity and also study the sound waveform, which is convenient for staff to analyze.

[0031] Example 2

[0032] Please see Figure 1 To ensure the equipment is in normal working condition, connection holes 11 are evenly provided on the left and right sides of the upper end face of the base plate 1. Expansion bolts are installed through the connection holes 11 to effectively fix the stability of the fixing box 2.

[0033] Working Principle: During use, expansion bolts are used to extend through the connecting hole 11 to the ground, ensuring the probe device is stably installed around the equipment. When the equipment needs to be tested, an external power supply can be connected according to the location of the noise generated by the equipment to start the servo motor 35. The servo motor 35 drives the lead screw 33 to rotate, and the limit port 32 and the connecting column 31 cooperate to limit the movement. The lead screw 33 drives the moving plate 34 to rise and fall, thereby driving the connecting column 31 to rise and fall. The connecting column 31 drives the probe device to the detection height. When it is necessary to detect the internal noise source of the equipment, the stepper motor 7 is started to rotate, driving the rotating disk 8 to rotate. The rotating disk 8 drives the fixed frame 10 to rotate, adjusting the direction of the probe device. The cylinder 95 is started, driving the telescopic column 94 to extend and retract. The vibrating diaphragm 92 receives the sound. The sound sensor 93 is electrically connected to the display screen, ensuring that the display screen 5 can display the sound intensity and also study the sound waveform, which is convenient for the staff to analyze.
