[0030] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Please refer to Figure 1-Figure 8The embodiment of the utility model provides an environmental noise monitoring device, including a pair of support rods 1, and a display 2 is installed between the pair of support rods 1. At the same time, the environmental noise monitoring device integrates data collection, transmission, publishing and display. Through high integration, flexible solutions and modular deployment, it can fully meet the use requirements of different occasions. Among them, the display 2 is an LED screen, and the LED screen display has an over-standard color change alarm display function. The integrated LED screen displays data. The screen adopts a P3.75 two-color unit board display. Daily data is displayed in green. When the equipment detects that the data exceeds the standard, the screen data area is driven to turn red.

[0032] This device is interconnected with on-site instruments through the Internet of Things technology to complete the real-time collection of environmental noise data, statistically analyze the collected data, and calculate the noise value. It is a simple outdoor noise automatic monitoring system, which consists of a large data display screen, noise sensor, data collection and statistical analysis software, GPRS wireless transmission module, server cloud platform software, WeChat client and other parts. The noise meter has a large measurement range, strong functions and good stability, and can realize remote video monitoring, remote broadcasting and other functions, thereby realizing online monitoring of social life noise.

[0033] In order to collect and monitor noise, a top plate 3 is provided on the upper side of the display 2. A through hole is opened at a portion of the top plate 3 close to one side. A hollow plate 4 is installed in the through hole. A noise collector 5 is installed at the center of the hollow plate 4. The noise collector 5 can be a microphone, a noise sensor or other device for collecting noise.

[0034] Taking into account that dust will accumulate on the noise collector 5 after long-term use, which will affect the quality of collected noise, a dust-proof component is provided on the hollow plate 4, and the dust-proof component includes an inner dust cover 14 located on the outside of the noise collector 5, the inner dust cover 14 is fixedly connected to the hollow plate 4, and at the same time, an outer dust cover 15 is sleeved on the outer side of the inner dust cover 14, and the lower side of the outer dust cover 15 is rotatably connected to the hollow plate 4, so that a double dust-proof effect is achieved by the inner dust cover 14 and the outer dust cover 15, thereby improving the dust-proof efficiency.

[0035] Furthermore, a brush 17 is installed on the inner side of the outer dust cover 15, and the brush 17 is in contact with the outer side of the inner dust cover 14. Therefore, when the outer dust cover 15 rotates, the brush 17 cleans the inner dust cover 14 to reduce dust on the inner dust cover 14 and improve the dustproof effect of the inner dust cover 14.

[0036] It is worth mentioning that a socket 6 is symmetrically opened at the bottom of the top plate 3, and a collection box 21 is inserted into the socket 6. The collection box 21 is located on the lower side of the inner dust cover 14. When the inner dust cover 14 is cleaned, dust will enter the collection box 21 through the hollow part of the hollow plate 4 and be stored.

[0037] At the same time, in order to achieve automatic cleaning, a gear ring 16 is provided at the lower end of the outer side of the outer dust cover 15, and a driving wheel 18 is rotatably provided on the top plate 3. The driving wheel 18 is driven by a micro motor, and the driving wheel 18 is engaged with the gear ring 16 to make the gear ring 16 automatically rotate with the outer dust cover 15.

[0038] Furthermore, considering that wind noise can easily affect noise monitoring when it is windy, a windproof component is installed on the top plate 3 outside the dustproof component, and the windproof component wraps the noise collector 5 to provide windproof.

[0039] The wind assembly includes a pair of L-shaped rods 7 fixed on the top plate 3, the upper ends of the L-shaped rods 7 are connected to the upper ends of the connecting rods 8, the connecting rods 8 are in a "U" shape, and the two sides of the connecting rods 8 are respectively connected to the sealing plate 9 and the annular ring 10. The sealing plate 9 is located inside the annular ring 10, and an annular gap is formed therebetween. At the same time, the sealing plate 9 is fitted with the upper side of the outer dust cover 15. The size of the sealing plate 9 is adapted to the size of the outer dust cover 15, so the upper sides of the outer dust cover 15 and the inner dust cover 14 can be sealed.

[0040] A wind shield 19 is slidably arranged in the annular gap formed by the sealing plate 9 and the annular ring 10. The size of the wind shield 19 is larger than that of the outer dust cover 15. Normally, the wind shield 19 is located at the upper end of the outer dust cover 15 and does not wrap the outer dust cover 15 to prevent it from reducing the quality of noise monitoring. When the wind speed sensor 13 installed on one side of the L-shaped rod 7 detects the wind force, it transmits the signal to the controller. The controller controls the motor driving the screw rod 12 to rotate the screw rod 12 on the top plate 3. At the same time, the screw rod 12 is on the inner side of the L-shaped rod 7. The extension plate threadedly connected to the screw rod 12 descends with the wind shield 19 to wrap the outer dust cover 15 and the noise collector 5, thereby reducing the influence of wind noise on noise collection.

[0041] When the extension plate moves, it is slidably connected with the connecting rod 8, so that the wind shield 19 moves horizontally.

[0042] In addition, a brush 20 is provided on the inner side of the wind shield 19, and the brush 20 is in contact with the outer side of the outer dust cover 15. At the same time, a notch 11 is provided on the sealing plate 9. Therefore, when the outer dust cover 15 rotates, the brush 20 cleans the outer dust cover 15 to reduce the dust on the outer dust cover 15. The notch 11 is provided so that the wind shield 19 can move up and down with the brush 20.

[0043] In summary, an environmental noise monitoring device according to an embodiment of the utility model has the following working principle: by providing a fixed inner dust cover 14 and a rotatable outer dust cover 15 on the outer side of the noise collector 5, the noise collector 5 is protected from dust. When the wind speed sensor 13 detects wind, the controller controls the motor to drive the screw 12 to rotate, so that the windproof cover 19 moves downward to seal the outer dust cover 15. At this time, if the driving wheel 18 and the gear ring 16 are meshed, the outer dust cover 15 rotates. At this time, the brush 17 cleans the inner dust cover 14, and the brush 2 20 cleans the outer dust cover 15.

[0044] When the outer dust cover rotates, the first brush cleans the inner dust cover, and the second brush cleans the outer dust cover, thereby improving the dustproof effects of the two.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
