Description

Technical Field

[0001] The utility model relates to the technical field of noise detection, in particular to an environmentally friendly noise detection device for a construction site. Background Art

[0002] A noise detection device is an instrument used to measure the noise level in an environment. According to different measurement principles and usage scenarios, noise detection devices can be divided into many types. On construction sites, noise pollution has an impact on the health of workers that cannot be ignored. Noise detection can promote the safety management of construction sites. There are often various noise sources on construction sites. These noise sources may distract the attention of workers and increase the probability of accidents on the construction site. Through noise detection, these safety hazards can be discovered in time, and measures can be taken to rectify them, thereby improving the safety of the construction site.

[0003] After searching, a Chinese patent with publication number CN216410397U discloses a construction site noise detection device. There are many noise detection devices on the market, but these noise detection devices are ubiquitous, with a relatively simple structure and no active warning function. In addition, since the shell of the noise detection device is fixed by multiple bolts, it is very inconvenient to inspect and disassemble. Therefore, a technician in this field provides a construction site noise detection device to solve the problems raised in the above background technology. Therefore, a buzzer, a noise sensor and a single-chip microcomputer are set. The noise sensor can convert the sound generated by the construction site into an electrical signal, and then transmit it to the single-chip microcomputer for calculation and processing. When the sound reaches the trigger value preset by the single-chip microcomputer, the buzzer is controlled to work, which solves the problem of a relatively simple structure and a lack of active warning function.

[0004] There are still some shortcomings in the use of the above-mentioned noise detection device. When detecting noise, it is usually necessary to transmit the noise to the noise detector for detection through a sound-absorbing tube. When working on a construction site, there is a lot of dust on the site. During the sound absorption process, the dust is scattered, which can easily cause the sound-absorbing tube to be covered with dust, thereby reducing the accuracy of noise detection and causing a lot of dust and impurities to exist inside the sound-absorbing tube, making it inconvenient to clean the tube, resulting in the inner wall of the tube being corroded by dust, thereby reducing the service life of the tube.
