[0002] The automatic noise detection device for gas meters is a device used to automatically monitor and detect the noise generated during the operation of gas meters. It integrates high-precision acoustic sensors to capture the sound signals emitted by the gas meter during operation. Through built-in signal processing algorithms and analysis software, it performs real-time analysis and processing of the collected sound data, which can accurately determine the intensity and frequency characteristics of the noise and compare them with preset standard thresholds. This allows for the automatic identification of whether there is abnormal noise in the gas meter, enabling effective monitoring and fault warning of the gas meter's operating status, ensuring the normal operation of the gas meter and the safety of users' gas usage.

[0003] A search revealed Chinese Patent Publication No. CN215178134U, which discloses an automatic noise detection device, relating to the field of noise detection technology.

An automatic setting device 6 is provided at the right end of the second data line 25. A lifting mechanism 2 is installed at the bottom of the mounting platform 1. The lifting mechanism 2 is used to lift the mounting platform 1. Fixed circular plates 21 are fixedly connected to both the left and right ends of the automatic pulse transmitter 12. A handle 20 is rotatably connected to the top of the fixed circular plate 21. A protective cover 19 is installed on the outside of the handle 20. The installation of the handle 20 facilitates the movement of the automatic pulse transmitter 12. A touch screen 13 is provided at the left front end of the automatic pulse transmitter 12. Multiple knobs 14 are equidistantly installed at the right front end of the automatic pulse transmitter 12. The installation of the touch screen 13 facilitates the display of data.

[0040] Specifically, after setting the detection parameters via the touchscreen 13, the PLC will automatically construct the detection sequence. During the execution phase, the motor 22 drives the first connecting plate 16 to rotate at a preset speed. It pauses for 0.5 seconds every five degrees of rotation to collect data. The automatic pulse transmitter 12 transmits a sweep frequency signal according to the set parameters. The noise signal received by the reflector probe 17 is converted and stored. During the data processing phase, the spectrum curve is displayed in real time, and abnormal frequency bands are automatically marked. After the detection is completed, a report will be generated. All these curves can be displayed on the touchscreen 13. Through the above process, the accuracy of the data can be improved.

[0041] Reference Figure 1 , Figure 3 and Figure 5The lifting mechanism 2 includes two first sliding boxes 201, which are fixedly connected to the front and rear ends of the bottom of the installation platform 1, respectively. A fixed rod 202 is fixedly connected inside each first sliding box 201. Sliding square plates 203 are slidably connected to the left and right ends of the fixed rod 202. Connecting rods 204 are rotatably connected to the bottom of each sliding square plate 203. A rotating cylinder 205 is rotatably connected to the middle of the connecting rod 204. A second sliding box 208 is provided at the bottom of the connecting rod 204. A bidirectional threaded rod 206 is rotatably connected inside the second sliding box 208. The left and right ends of the bidirectional threaded rod 206 are threaded. The movable square plate 207 is connected to the bidirectional threaded rod 206, which allows the movable square plate 207 to move towards each other. The top of the movable square plate 207 is rotatably connected to the bottom of the connecting rod 204. The right end of the bidirectional threaded rod 206 is fixedly connected to the rotating round rod 3. The right end of the rotating round rod 3 passes through the right end of the second slide box 208 and is fixedly connected to the turntable 4. The installation of the turntable 4 facilitates the rotation of the rotating round rod 3. The four corners of the bottom of the installation platform 1 are fixedly connected to the telescopic column 11. The top of the installation platform 1 is provided with a rubber pad 5. The installation of the telescopic column 11 makes the device more stable.

[0042] Specifically, when the height of the installation platform 1 needs to be adjusted, first rotate the turntable 4, causing the rotating rod 3 to rotate accordingly, which in turn causes the bidirectional threaded rod 206 to rotate. Since the bidirectional threaded rod 206 is located inside the second slide box 208, its rotation will drive the movable square plate 207 connected by the outer thread to move towards each other inside the second slide box 208. When the movable square plate 207 moves, the connecting rod 204 rotatably connected to its top will rotate accordingly. The two connecting rods 204 are connected by the rotating cylinder 205, which causes the two sliding square plates 203 to slide outside the fixed rod 202. Through the above process, the lifting and lowering of the installation platform 1 is realized, which facilitates the testing of this device.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The right end of the mounting platform 1 is fixedly connected to a slot plate 10, and a notice board 9 is installed inside the slot plate 10. The top, front and rear ends of the automatic setting device 6 are threaded with screws 24, and a connecting bent plate 23 is installed in the middle of the screws 24. The front side of the automatic setting device 6 is fixedly connected to an installation ring 8, and a display screen 7 is installed inside the installation ring 8.

[0044] Specifically, the installation of the card slot plate 10 facilitates the replacement of the notice board 9, the installation of the notice board 9 facilitates the reminder to the staff, the installation of the connecting bend plate 23 facilitates the movement of the automatic setting device 6, and the installation of the display screen 7 facilitates the observation of data.

[0045] Working principle: The detection parameters are set through the touch screen 13, and the PLC automatically generates the detection sequence. During the execution phase, the motor 22 drives the first connecting plate 16 to rotate at the set speed. It pauses for 0.5 seconds every five degrees of rotation to collect data. The automatic pulse transmitter 12 transmits a sweep frequency signal according to the preset parameters. The noise signal received by the reflector probe 17 is converted and stored. During data processing, the spectrum curve is displayed in real time, and abnormal frequency bands are automatically marked. A report is generated after the detection is completed. All of the above curves can be displayed on the touch screen 13.

[0046] When the height of the installation platform 1 needs to be adjusted, the turntable 4 is rotated, causing the rotating rod 3 to rotate, which in turn causes the bidirectional threaded rod 206 to rotate. Since the bidirectional threaded rod 206 is located inside the second slide box 208, its rotation will drive the movable square plate 207 connected by the outer thread to move towards each other inside the second slide box 208. When the movable square plate 207 moves, the connecting rod 204 rotatably connected to its top will rotate accordingly. The two connecting rods 204 are connected by the rotating cylinder 205, which causes the two sliding square plates 203 to slide outside the fixed rod 202. Through the above process, the lifting and lowering of the installation platform 1 is realized, which facilitates the testing of this device.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
