[0001] This utility model relates to the field of sound field data monitoring, and in particular to a real-time sound field data monitoring device. Background Technology

[0002] A sound field is a region in a medium where sound waves exist. The physical quantities that describe a sound field can be sound pressure, particle vibration velocity, displacement, or medium density, etc., which are generally functions of position and time.

[0003] Real-time sound field data monitoring devices can measure and monitor the data of sound field sources in real time, process the monitored data, analyze the distribution characteristics of the sound field, detect the location and intensity of sound sources, evaluate the quality of the acoustic environment, and provide a basis for acoustic design and optimization.

[0004] Traditional real-time sound field data monitoring devices collect sound field information directly from the data collector and then transmit it to subsequent components for analysis and processing. Over time, dust in the air can enter the device and accumulate, clogging the collector and making it difficult to clean, thus affecting the quality and efficiency of subsequent monitoring. Utility Model Content

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-4 This utility model provides an embodiment of a real-time sound field data monitoring device, comprising a protective shell 1, a first filter 2 fixedly installed on the outer wall of the protective shell 1, a first filter cotton 3 fixedly connected to the rear side of the first filter 2, a second filter 4 fixedly installed on the inner wall of the protective shell 1, a second filter cotton 5 fixedly connected to the rear side of the second filter 4, a collection frame 6 slidably connected to the inner wall of the protective shell 1, a fixing plate 11 fixedly connected to the inner wall of the protective shell 1, a motor 12 fixedly connected to the outer wall of the fixing plate 11, a worm gear 15 fixedly connected to the output end of the motor 12, a second limiting post 23 fixedly connected to the outer wall of the fixing plate 11, and a worm gear 15 rotatably connected to one end of the second limiting post 23. The outer wall of the worm gear 16 is fixedly connected to a first connecting rod 17. One end of the first connecting rod 17 is hinged to a second connecting rod 18. Both ends of the second connecting rod 18 are hinged to a beater rod 19. A heat dissipation assembly is provided on the rear side of the protective shell 1. Multiple limiting plates 13 are fixedly connected to the outer wall of the fixing plate 11. The worm gear 15 is rotatably connected to the inner wall of two of the limiting plates 13. Multiple first limiting posts 14 are fixedly connected to the outer wall of the fixing plate 11. The beater rod 19 is hinged to one end of the first limiting post 14. The collection frame 6 is located directly below the first filter cotton 3 and the second filter cotton 5. The worm gear 15 and the worm wheel 16 are meshed and connected. A handle 8 is fixedly installed on the top of the protective shell 1.

[0027] Specifically, the entire device is protected by a protective shell 1 to enhance stability. Firstly, a first filter element 2 and a first filter cotton 3 form the first dust filter. Secondly, a second filter element 4 and a second filter cotton 5 are installed on the inner wall of the protective shell 1 to form the second dust filter. This dual filtration ensures that dust cannot enter the device and affect component operation. A sliding collection frame 6 located below the two filters allows for convenient dust removal during use. A fixing plate 11 is welded to the inner wall of the protective shell 1, on which a dust-beating component is installed for stability. A motor 12, multiple limiting plates 13, and a first limiting post 14 are fixedly mounted on the outer wall of the fixing plate 11. The inner walls of the two limiting plates 13 are rotatably connected to a worm gear 15 on opposite sides, driven by the output of the motor 12. A second limiting post 23 is also welded to the fixing plate 11, with its other end rotatably connected to a worm wheel 16, ensuring that the worm wheel 16 is positioned directly above the worm gear 15. Above, the two are connected by meshing. When the worm gear 15 rotates, it will drive the worm wheel 16 to rotate continuously. Because the outer wall of the worm wheel 16 is also fixedly connected to one end of the first connecting rod 17, and because the other end of the first connecting rod 17 is hinged to the second connecting rod 18, one end of the first connecting rod 17 will rotate with the worm wheel 16, and the other end will be driven to move around the hinge point, thus continuing to drive the second connecting rod 18 to move through the hinge relationship. Since both ends of the second connecting rod 18 are connected to the beater rods 19 through the hinge relationship, the two beater rods 19 will rotate around the hinge point with the first limiting post 14, and their other ends will be driven to continuously beat the first filter cotton 3 and the second filter cotton 5. Through vibration, the filtered dust on them will be knocked off and fall into the collection frame 6 directly below. This completes the dust filtration and treatment of the entire device, ensuring long-term use of the device and extending its service life. The design of the top handle 8 ensures the portability of the device.

[0028] Reference Figure 5 and Figure 6 The heat dissipation assembly includes a heat dissipation conduit 21, the outer wall of which is fixedly installed on the inner wall of the protective shell 1. One end of the heat dissipation conduit 21 is fixedly connected to a heat sink 20. Multiple fans 22 are fixedly installed on the rear side of the protective shell 1. A screen 7 is fixedly installed on the outer side of the protective shell 1. A data collector 9 and a data display 10 are fixedly installed on the inner wall of the protective shell 1. The heat sink 20 is fixedly installed on the outer wall of the data collector 9 and the data display 10. The screen 7 is electrically connected to the data collector 9 and the data display 10.

[0029] Specifically, the sound field data is received by the data collector 9 through two filters, processed, and then transmitted to the data display 10 via wires. Finally, the required data is displayed on the screen 7 to complete the monitoring. When used for a long time, the heat generated by the data collector 9 and the data display 10 is absorbed by the heat sink 20 and then transferred to the heat pipe 21 for even distribution. The multi-section bending design of the heat pipe 21 increases the heat dissipation area and enhances the heat dissipation effect. The two fans 22 installed on the back of the protective shell 1 ensure the accelerated exhaust and cooling of heat, further enhancing heat dissipation and ensuring the efficiency of the device during long-term operation. At the same time, the impact of the silent fans 22 on the sound field data monitoring can be eliminated by installing them.

[0030] In one predictable implementation, a PLC controller is used to control the motor, enabling it to periodically beat dust. In this periodic scenario, the noise generated is relatively stable and predictable by the beating rod of this device, thus ensuring that it does not interfere with long-term monitoring.

[0031] Working principle: When the real-time sound field data monitoring device is needed, first pull the handle 8 to place it in a suitable position, start the device, and the sound field data passes sequentially through the first filter 2, the first filter cotton 3, the second filter 4, and the second filter cotton 5 to the data collector 9. After being collected and processed by the data collector 9, it is sent to the data display 10 and finally displayed on the screen 7. When used for a long time, dust will accumulate on the two filters and the filter cotton. At this time, start the motor 12. The motor 12 will drive the worm gear 15 connected to its output end to rotate. Then, due to the meshing relationship, the worm gear 15 will drive the worm wheel 16 directly above it to rotate. Then, one end of the first connecting rod 17 fixed to the outer wall of the worm wheel 16 will rotate as well. The other end of 7 will also be moved, which will drive the second connecting rod 18 and the tapping rod 19, which are hinged to the other end of the first connecting rod 17, to move synchronously. Since the tapping rod 19 is fixed on the first limiting post 14, the tapping rods 19 at both ends of the second connecting rod 18 will tap the first filter cotton 3 and the second filter cotton 5 synchronously, knocking the dust absorbed on them down into the collection box 6 directly below, thus completing the cleaning and collection of dust. When the dust is finished, the collection box 6 can be pulled out to empty it. During long-term use, the heat generated by the data collector 9 and the data display 10 will be absorbed by the heat sink 20 attached to its back, and then evenly transferred to the heat pipe 21, and carried out by the fan 22 to prevent overheating from affecting the operating efficiency of the device.

[0032] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
