Description

Technical Field

[0001] This utility model relates to the field of noise monitoring technology, specifically to an outdoor noise monitoring device. Background Technology

[0002] Currently, environmental noise has become the fourth largest source of pollution after exhaust gas, wastewater, and solid waste. In some enterprises, areas with frequent high noise pollution, construction sites, near railways and airports, roads with high traffic volume, and around a large number of high-rise buildings in cities, there is serious noise pollution, which has a great impact on people's production and life.

[0003] Chinese Patent CN209858061U discloses a construction site noise monitoring system based on a microcontroller, including a frame, a filter, and a monitor. The frame includes a sleeve and a cover. The sleeve is arranged vertically, and multiple downward-sloping ventilation holes are opened on the sleeve wall. The monitor is installed inside the sleeve, and the filter is placed between the sleeve and the monitor. The cover is detachably installed on the sleeve. The sleeve and cover reduce construction dust falling onto the monitor. Since there are ventilation holes on the sleeve, it does not affect the monitor's detection of construction site noise, and the heat generated by the monitor during operation can be dissipated to the outside through the ventilation holes in a timely manner. The downward-sloping ventilation holes can prevent rainwater from entering the sleeve and damaging the monitor when the device is used outdoors. In addition, some dust may still fall onto the monitor through the ventilation holes, so a filter is also provided to filter out this dust, thereby extending the service life of the monitor.

[0004] However, the above technical solution has the following shortcomings: the scraper can only scrape off the dust attached to the inner wall of the filter screen, but cannot clean the dust attached to the outer surface of the filter screen. If it is not effectively cleaned for a long time, it will easily cause the ventilation holes to be blocked, affecting the detection accuracy of the monitor. Utility Model Content
