[0002] The importance of environmental noise detection lies in its ability to effectively evaluate and improve the quality of the environment in which people live, and protect the public from the physical and mental health effects of noise pollution. By accurately monitoring the source and intensity of noise, we can not only provide a scientific basis for urban planning and environmental management, but also provide effective guidance for noise control in industries, construction, transportation and other fields.

[0003] Traditional environmental noise detection devices mainly include fixed detection devices and rotating detection devices.

[0004] The fixed device achieves all-round detection of ambient noise through multi-point monitoring, which is stable and reliable but has a limited monitoring range. The rotating device expands the monitoring range by rotating the sensor, which is more flexible, but since it cannot rotate continuously, there are blind spots in monitoring and the structure is relatively complex.

[0005] Therefore, there is a need for an environmental noise detection device capable of multi-directional detection to solve the above problems. Utility Model Content

[0008] Preferably, the upper and lower corners of the device housing are fixed by connecting bolts.

[0009] Preferably, the driving motor is a brushless stepping motor.

[0011] Preferably, an adjustment bracket is installed on the upper end of the adjustment base, and the upper end of the adjustment bracket is fixed to the lower end of the sound collector.

[0012] Preferably, an adjusting bolt is provided at the connection between the adjusting base and the adjusting bracket.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the noise sensor in the utility model can flexibly rotate in the sensor bracket through the second bearing. The noise sensor installed inside the sensor bracket through the second bearing is designed to allow the noise sensor to rotate through the stress of the connecting line when the sound collector rotates, and the rotation of the sound collector driven by the driving motor can realize continuous all-round rotation of the noise sensor, thereby eliminating the monitoring blind spot in the traditional rotation detection device.

The device shell 1 serves as the main body of the entire device and provides stable protection for the internal components; the driving motor 21 in the driving component 2 is the power source of the device, which generates power through rotation, thereby driving the entire detection device to rotate; the design of the angle adjustment component 3 allows the sound receiving component 4 to be flexibly adjusted in the horizontal direction, thereby expanding the detection range; the noise sensor 44 flexibly rotates in the sensor bracket 42 through the second bearing 43, and cooperates with the rotation of the sound collector 41 driven by the driving motor 21, thereby realizing the continuous all-round rotation of the noise sensor 44, thereby eliminating the monitoring blind spot in the traditional rotation detection device.

[0022] The upper and lower corners of the device housing 1 are fixed by connecting bolts 11. By using the connecting bolts 11 for fixing, the device housing 1 is more convenient and quick during assembly, and is also convenient for subsequent disassembly and maintenance.

[0023] The drive motor 21 is a brushless stepper motor, which adopts electronic commutation technology and eliminates traditional brushes and collector rings, thereby eliminating friction loss and electrical loss caused by brush wear and mechanical commutator.

[0024] The angle adjustment assembly 3 includes an adjustment base 31 , which is fixed to the upper end of the second synchronous wheel 23 , so that the adjustment base 31 can be driven to rotate when the second synchronous wheel 23 moves.

[0025] An adjusting bracket 32 ​​is installed on the upper end of the adjusting base 31 . The upper end of the adjusting bracket 32 ​​is fixed to the lower end of the sound collector 41 , so that the sound collector 41 can rotate along with the movement of the adjusting base 31 .

[0027] As an embodiment of the utility model: when the environmental noise detection device capable of multi-directional detection is used, the drive motor 21 is first started, the drive motor 21 starts to rotate, and the power is transmitted to the second synchronous wheel 23 through the engagement of the first synchronous wheel 22 and the second synchronous wheel 23. Since the second synchronous wheel 23 is a hollow structure, the lower end of the noise sensor 44 is connected to the control board 46 inside the device shell 1 through the connecting line 45, so the noise sensor 44 can rotate with the rotation of the second synchronous wheel 23; the noise sensor 44 is flexibly rotated in the sensor bracket 42 through the second bearing 43, and this rotation is combined with the rotation of the sound collector 41 to achieve all-round continuous rotation of the noise sensor 44. The noise sensor 44 can detect noise in the environment without dead angles, eliminating the monitoring blind spots in traditional rotation detection devices. The noise signals sensed by the noise sensor 44 will be transmitted to the control board 46 through the connecting line 45. The control board 46 will process and analyze these signals to derive the noise level and distribution in the environment, thereby completing the use of the environmental noise detection device capable of multi-directional detection.
