Description

Technical Field

[0001] The utility model relates to the technical field of noise detection devices, in particular to an environmental noise detection device. Background Art

[0002] Noise tester, also called noise detector, is an instrument used for noise detection and testing in public places such as work sites and squares. Noise pollution is one of the most influential environmental pollution. High decibel noise can even cause serious damage to the eardrum and cause deafness.

[0003] At the construction site, it is often necessary to arrange noise testers to detect the noise during construction during the day and at night. In particular, construction sites close to residential areas attach greater importance to noise control. Generally, noise testers at construction sites are installed in the air at a distance from the ground through support poles. When inspecting and servicing them, workers need to use climbing tools such as escalators for maintenance, which may lead to the risk of falling. In addition, existing noise detection devices are mostly fixed to the top of the support poles by multiple sets of bolts. When they need to be disassembled for maintenance, workers use disassembly tools such as wrenches to disassemble the bolts one by one, which is time-consuming and labor-intensive, and the disassembly is not convenient enough. Therefore, an environmental noise detection device is proposed to solve the above-mentioned technical problems. Utility Model Content
