Description

Technical Field

[0001] This invention relates to the field of industrial acoustics technology, specifically to an acoustic imaging leak detection, monitoring, and early warning device. Background Technology

[0002] Acoustic imaging leak detection, monitoring and early warning device is an intelligent detection device that combines microphone array acquisition, acoustic signal processing and real-time imaging algorithms. The core of the working process of the acoustic imaging leak detection, monitoring and early warning device is a closed-loop process of "sound wave acquisition → signal processing → imaging positioning → monitoring and early warning". In essence, it converts the invisible sound waves generated by the leak into a visual image and monitors the anomaly in real time.

[0003] Patent application CN202410739620.0 discloses a gas leak detection device using infrared imaging, including a mobile frame, a mobile vehicle slidably mounted in the middle of the mobile frame, a monitoring device fixedly connected to the bottom of the mobile vehicle, a detection component fixedly connected to one side of the monitoring device, a controller, a wireless transmission module and a locator installed inside the monitoring device, the controller being connected to a cloud platform through the wireless transmission module and wirelessly connected to a mobile terminal through the cloud platform.

[0004] However, this patent also has the following shortcomings: when gas leaks, it will generate sound waves of a specific frequency, and the microphone array in the device will collect the leaking sound waves. The direction of sound wave propagation can be calculated by beamforming algorithm. However, during the collection process, water vapor and dust in the factory workshop will block the microphone pickup hole and block the visible light camera, resulting in blurred acoustic images. In view of this situation, an acoustic imaging leak detection, monitoring and early warning device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an acoustic imaging leak detection, monitoring and early warning device to solve the problems mentioned in the background art.

A sound tube is fixedly connected to the top of the absorption tank. A covering assembly is provided at the grooves on the surface of the absorption tank. A cleaning mechanism is provided on the surface of the monitor. Suction is generated inside the conveying ring, thereby absorbing external air into the interior through the absorption grooves on the surface of the conveying ring.

[0010] According to the above technical solution, the covering component includes a fixing ring, the two ends of which are slidably connected to the surface slots of the absorption tank via sliders, a covering ring is fixedly connected to the surface of the fixing ring, a discharge pipe is fixedly connected to the inner wall of the covering ring, an adsorption chamber is fixedly connected to the surface of the covering ring, and a conveying pipe is fixedly connected to the bottom of the covering ring. The end of the conveying pipe away from the covering ring is fixedly connected to the inner wall of the absorption tank, and the gas is sprayed outward through multiple discharge pipes inside the covering ring.

[0011] According to the above technical solution, the adsorption chamber is provided with an adsorption groove inside, activated carbon is installed inside the adsorption chamber, the surface of the discharge pipe is provided with a pipe groove, the surface of the conveying ring is provided with an absorption groove, and the inside of the conveying chamber is provided with a conveying groove. When the fixed ring rotates, it adsorbs dust in the air through multiple adsorption pads covering the surface of the ring.

[0012] According to the above technical solution, the cleaning mechanism includes a connecting plate, which is fixedly connected to the surface of the monitor. A spray valve is fixedly connected to the bottom of the connecting plate, and connecting arms are fixedly connected to both sides of the connecting plate.

[0013] According to the above technical solution, the discharge assembly includes a positioning frame, which is fixedly connected to the surface of the connecting plate. An air inlet pipe is fixedly connected to the inner wall of the positioning frame, and the end of the air inlet pipe away from the positioning frame is fixedly connected to the inner wall of the connecting plate. A support frame is fixedly connected to the inner wall of the positioning frame, and one end of the support frame is fixedly connected to the surface of the connecting plate. A connecting pipe is fixedly connected to the left side of the positioning frame, and the end of the connecting pipe away from the positioning frame is fixedly connected to the surface of the conveying ring. A discharge plate is fixedly connected to the top of the positioning frame, and compressed gas is discharged into the internal cavity of the connecting plate through the air inlet pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting a fixing mechanism, pulls the push frame to open one end of the plug cover from the chassis surface. At this time, the bottom covering box is no longer fixed to the chassis surface, allowing one end of the covering box to rotate on the inner wall of the chassis. When multiple movable covering boxes on the inner wall of the chassis come into contact with the detection position, the adsorption pad at the bottom of the compression membrane adsorbs the detection position, thereby fixing the leak detection device at the detection position. By setting this mechanism, the multiple movable covering boxes inside the chassis can more flexibly fix the leak detection device at the inclined detection position.

[0015] 2. This invention, by setting up a conveying mechanism, drives the fixed ring to rotate continuously left and right at the slots on the surface of the absorption tank by activating the internal controller switch of the fixed ring. During the rotation of the fixed ring, multiple adsorption pads covering the surface of the ring adsorb dust in the air, while multiple discharge pipes blow the dust in the factory workshop to the outside through the compressed gas sprayed outward. By setting up this mechanism, when the microphone array collects the special sound waves generated during leakage, the dust around the microphone array is blocked, thereby effectively preventing the dust from clogging the microphone array.

[0016] 3. This invention, by setting up a cleaning mechanism, discharges compressed gas into the internal cavity of the connecting plate through the air inlet pipe, and then sprays the gas outward through the ejection valve at the bottom of the connecting plate. At the same time, the connecting arms on both sides of the connecting plate can spray the compressed gas outward through the ejection chamber on the inner wall. The ejection chamber and ejection valve are set around the monitor camera. The compressed gas sprayed out can blow away the dust around the camera. By setting up this mechanism, the surface of the monitor camera can be precisely cleaned, avoiding dust in the factory workshop from blocking the visible light camera and causing the acoustic image to become blurry.

[0017] 4. By setting up an adsorption component, when the adsorption pad at the bottom of the compressed membrane comes into contact with the detection position, the cleaning ring at the bottom of the adsorption pad can sweep away the dust and moisture at the detection position. This avoids the dust and moisture on the bottom of the adsorption pad affecting the adsorption effect at the detection position when the adhesive adheres to the placement area. By setting up this component, the leak detection device can be fixed while avoiding the influence of moisture and dust in the factory workshop on the adsorption effect of the adsorption pad.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Example 1: See Figures 1-4This invention provides a technical solution: an acoustic imaging leak detection, monitoring, and early warning device, comprising a chassis 1, a support column 2 fixedly connected to the top of the chassis 1, a monitor 3 fixedly connected to the top of the support column 2, an alarm 5 fixedly connected to the right side of the monitor 3, a camera 4 fixedly connected to the surface of the monitor 3, and a fixing mechanism 6 provided on the inner wall of the chassis 1; the operator can hold the support column 2 and capture the characteristic sound waves generated when the pipeline leaks through the microphone array built into the monitor 3, filter background noise through algorithms, retain only the characteristic sound waves generated by the leak, and use beamforming, delay superposition, and other algorithms to convert the sound wave signal into a color acoustic image displayed on the screen of the monitor 3, thereby monitoring the changes in the acoustic image in real time, and automatically triggering the alarm 5 when the leakage intensity exceeds a set threshold.

[0024] The fixing mechanism 6 includes a covering box 601. The two sides of the covering box 601 are rotatably connected to the inner wall of the chassis 1 via rotating shafts. A rotating frame 602 is fixedly connected to the top of the covering box 601. An insertion cover 603 is rotatably connected to the inner wall of the rotating frame 602 via a rotating shaft. A pushing frame 604 is fixedly connected to the top of the insertion cover 603. An adsorption component 605 is provided on the inner wall of the covering box 601. However, sometimes the sound waves of gas leakage inside the pipeline are interfered with by background noise, resulting in a smaller sound wave generated when the gas leaks. Therefore, it is necessary to monitor the pipeline for a long time through an acoustic imaging leak monitoring device. At this time, by pulling the pushing frame 604, one end of the insertion cover 603 is pulled away from the surface of the chassis 1. At this time, the bottom of the covering box 601 is no longer fixed to the surface of the chassis 1, so that one end of the covering box 601 can rotate on the inner wall of the chassis 1.

[0025] The adsorption assembly 605 includes a compression membrane 6051, which is fixedly connected to both sides of the inner wall of the covering box 601. An adsorption pad 6052 is fixedly connected to the bottom of the inner wall of the compression membrane 6051, and a cleaning ring 6053 is fixedly connected to the bottom of the adsorption pad 6052. A conveying mechanism 7 is provided on the top of the monitor 3. When multiple movable covering boxes 601 on the inner wall of the chassis 1 come into contact with the detection position, the adsorption pad 6052 at the bottom of the compression membrane 6051 adsorbs the detection position, thereby fixing the leak detection device at the detection position. Through the multiple movable covering boxes 601 inside the chassis 1, the leak detection device can be fixed more flexibly at the inclined detection position.

[0026] When using a leak detection device to monitor internal pipelines in a factory for an extended period of time, it is important to note that there is a large amount of water vapor and dust inside the pipelines. This can affect the adsorption effect of the adsorption device at the bottom of the leak detection device, so an adsorption component 605 needs to be installed.

[0027] The surface of the chassis 1 is provided with a plug hole, and the inner wall of the plug cover 603 is fixed with a plug post. The cleaning ring 6053 has compressibility. When the adsorption pad 6052 at the bottom of the compression film 6051 comes into contact with the detection position, the cleaning ring 6053 at the bottom of the adsorption pad 6052 can sweep away the dust and moisture at the detection position, thereby preventing the dust and moisture at the bottom of the adsorption pad 6052 from affecting the adsorption effect of the adsorption pad 6052 at the detection position when the adhesive at the bottom of the adsorption pad 6052 adsorbs the placement area.

[0028] The cleaning ring 6053 has a cleaning groove on its surface, and the adsorption pad 6052 has an adsorption groove at its bottom. After cleaning the dust and moisture at the detection position, the support column 2 is held to push the compression membrane 6051, which causes the surface of the compression membrane 6051 to be stressed and push the cleaning ring 6053. This causes one end of the cleaning ring 6053 to be stressed and contracted inward, thereby adsorbing and fixing the adsorption pad 6052 to the detection position. While fixing it with the leak detection device, this also prevents moisture and dust in the factory workshop from affecting the adsorption effect of the adsorption pad 6052.

[0029] Example 2: Based on Example 1, please refer to the following... Figures 5-6 The present invention provides a technical solution: the conveying mechanism 7 includes an absorption tank 701, which is fixedly connected to the top of the monitor 3. A conveying cavity 702 is fixedly connected to the surface of the absorption tank 701, which is also fixedly connected to the top of the monitor 3. An absorber 703 is fixedly connected to the end of the conveying cavity 702 away from the absorption tank 701, which is fixedly connected to the surface of the monitor 3. A conveying ring 704 is fixedly connected to the bottom of the absorber 703, which is also fixedly connected to the surface of the monitor 3. A microphone 705 is fixedly connected to the top of the absorber 701, and a cover assembly 706 is provided at the groove on the surface of the absorber 701. A cleaning mechanism 8 is provided on the surface of the monitor 3. When the leak detection device is fixed, the microphone array inside the absorber 701 can collect the special sound waves generated when the pipeline leaks through the absorption groove on the surface of the microphone 705. During the collection process, by turning on the switch of the absorber 703, a suction force is generated inside the conveying ring 704, thereby drawing external air into the interior through the absorption groove on the surface of the conveying ring 704.

[0030] The covering assembly 706 includes a fixing ring 7061, the two ends of which are slidably connected to the surface slots of the absorption tank 701 via sliders. A covering ring 7062 is fixedly connected to the surface of the fixing ring 7061, a discharge pipe 7064 is fixedly connected to the inner wall of the covering ring 7062, an adsorption chamber 7063 is fixedly connected to the surface of the covering ring 7062, and a delivery pipe 7065 is fixedly connected to the bottom of the covering ring 7062. The end of the delivery pipe 7065 away from the covering ring 7062 is connected to the inner wall of the absorption tank 701. The gas is compressed by the absorber 703 and discharged at high speed into the absorber tank 701 through the conveying chamber 702. The compressed gas is uniformly fed into the internal cavity of the covering ring 7062 through the conveying groove at the bottom of the absorber tank 701 via the conveying pipe 7065. The gas is then sprayed outward through multiple discharge pipes 7064 inside the covering ring 7062. At this time, by activating the internal controller switch of the fixed ring 7061, the fixed ring 7061 is driven to rotate continuously left and right at the slot on the surface of the absorber tank 701.

[0031] Dust inside the factory workshop can clog the microphone array inside the leak detection device, which will affect the acquisition effect of the special sound waves generated when the pipeline leaks. Therefore, it is necessary to install a cover component 706.

[0032] The adsorption chamber 7063 has an adsorption groove inside, and activated carbon is installed inside the adsorption chamber 7063. The surface of the discharge pipe 7064 has a pipe groove, the surface of the conveying ring 704 has an absorption groove, and the inside of the conveying chamber 702 has a conveying groove. When the fixed ring 7061 rotates, the dust in the air is adsorbed by multiple adsorption pads 6052 covering the surface of the ring 7062. At the same time, the dust in the factory workshop is blown to the outside by the compressed gas sprayed through multiple discharge pipes 7064. By setting this mechanism, when the microphone array collects the special sound waves generated during leakage, the dust around the microphone array is blocked, thereby effectively preventing the dust from clogging the microphone array.

[0033] Example 3: Based on Example 2, please refer to the following... Figures 7-8The present invention provides a technical solution: the cleaning mechanism 8 includes a connecting plate 801, which is fixedly connected to the surface of the monitor 3. A spray valve 802 is fixedly connected to the bottom of the connecting plate 801. Connecting arms 804 are fixedly connected to both sides of the connecting plate 801. A spray chamber 805 is fixedly connected to the inner wall of the connecting arm 804. A snap-fit ​​bracket 803 is fixedly connected to the surface of the connecting plate 801. The snap-fit ​​bracket 803 is fixedly connected to the surface of the monitor 3. A discharge component 806 is provided on the surface of the monitor 3. When the absorber 703 compresses and transports the gas through the conveying ring 704, the absorber on the surface of the positioning frame 8061 is first activated to generate suction. Then, the gas inside the conveying ring 704 is absorbed into the positioning frame 8061 through the connecting pipe 8065. The compressed gas is discharged into the cavity inside the connecting plate 801 through the air inlet pipe 8063. The gas is sprayed outward through the spray valve 802 at the bottom of the connecting plate 801.

[0034] The discharge assembly 806 includes a positioning frame 8061, which is fixedly connected to the surface of a connecting plate 801. An air inlet pipe 8063 is fixedly connected to the inner wall of the positioning frame 8061. One end of the air inlet pipe 8063, away from the positioning frame 8061, is fixedly connected to the inner wall of the connecting plate 801. A support frame 8062 is fixedly connected to the inner wall of the positioning frame 8061. One end of the support frame 8062 is fixedly connected to the surface of the connecting plate 801. A connecting pipe 8065 is fixedly connected to the left side of the positioning frame 8061. The connecting pipe 8065 is located away from the positioning frame 8061. One end is fixedly connected to the surface of the conveying ring 704, and the top of the positioning frame 8061 is fixedly connected to the discharge plate 8064. At the same time, the connecting arms 804 on both sides of the connecting plate 801 can spray compressed gas outward through the spray chamber 805 on the inner wall. The spray chamber 805 and the spray valve 802 are set around the camera 4 of the monitor 3. The compressed gas sprayed out can blow away the dust around the camera 4. By accurately cleaning the surface of the camera 4 of the monitor 3, the dust inside the factory workshop can be prevented from blocking the visible light camera 4, resulting in blurred acoustic images.

[0035] Dust inside the factory workshop can obscure the visible light camera 4, causing the acoustic image to become blurry. The current technology only involves manually wiping the camera 4, which is inefficient. Therefore, a cooling component 806 is needed.
