Description

Technical Field

[0001] This utility model relates to the field of noise detection technology, specifically to a portable highway traffic noise monitoring device. Background Technology

[0002] A noise meter is an instrument used for noise detection and testing in workplaces, public places such as squares, and other public areas. Noise pollution is one of the most significant forms of environmental pollution; high-decibel noise can even cause serious damage to the eardrums, leading to hearing loss. Noise meters provide the decibel level of noise levels, allowing for appropriate measures to control and reduce it. The unit of measurement for sound volume is decibels. Professional noise meters feature highly sensitive sensors, high accuracy, and a wide range of applications, making them suitable for noise measurement in various environments. They are also compact and portable.

[0003] A search revealed application number CN202011425051.0, entitled "A Portable Noise Detector." This application addresses the problem that existing portable noise detectors, when used in humid environments, suffer from poor ventilation, allowing moisture to easily enter the detector and causing internal dampness, thus affecting its lifespan. The application addresses this issue by using a sliding groove, slider, rack, gear, cam, movable rod, piston, and inner housing. When the slider slides within the groove, the rack also slides relative to the outer housing. Simultaneously, the rack drives the gear to rotate, which in turn drives the cam to rotate. The cam periodically compresses the movable rod, which in turn periodically compresses the inner housing. During the process of gas flow, outside air enters the outer shell through the outer hole, and the gas inside the outer shell can also be discharged through the inner hole, preventing the circuit of the outer shell from getting damp and protecting the device. Moreover, the handle can slide through the interaction of the sliding groove and the sliding strip, thereby adjusting the total length between the handle and the outer shell for easy carrying. However, this application requires repeated manual adjustment by the staff when extending and retracting, which is quite troublesome. At the same time, the airflow formed during the gas flow will also generate additional noise, affecting the accuracy of monitoring. When it rains, the impact of rainwater on the outer shell will also generate noise, affecting the monitoring results. Further improvements can be made.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0018] Compared with the prior art, the present invention provides a portable highway traffic noise monitoring device, which has the following advantages:

[0019] (1) This utility model adopts a foot-operated air pump and a deflation valve. The staff can fix the device to one side of the highway guardrail through the slot. Then, they can step on the foot-operated air pump to inject gas into the vertical cylinder. The gas pushes the piston to move upward, which in turn pushes the top box to move upward, completing the rapid deployment and installation. The highway noise enters the top box after being collected by the horn. The decibel meter detects the noise. When retracting, simply open the deflation valve to release the gas inside the vertical cylinder, and the device can be quickly retracted. After retracting, the height of the device is reduced, making it easy to carry. Compared with the traditional height adjustment structure, the height adjustment of this device is more convenient, and it is also very quick and convenient to retract, improving the ease of use.

[0020] (2) This utility model uses a desiccant and sound-absorbing cotton. The desiccant is located inside the top box. The moisture in the air is absorbed by the desiccant, which helps to keep the inside of the top box dry and will not generate additional noise, thus improving the accuracy of noise monitoring. At the same time, the roof serves as a rain shield to prevent rainwater from affecting the monitoring. The sound-absorbing cotton on the top surface of the roof can act as a rainwater buffer to prevent rainwater from hitting the roof and generating additional noise that affects the monitoring results, thus improving the accuracy of monitoring.
