Description

Technical Field

[0001] The utility model relates to the field of noise detection, in particular to a sensor for detecting noise in urban acoustic environments. Background Art

[0002] Noise monitors are widely used in outdoor environments, especially in construction sites, because the noise generated during construction can easily affect the rest of the surrounding neighbors, so noise monitors are needed to control the noise at the construction site. Construction units do not need to carry out construction in windy weather, but in windy weather, the sound of wind is also a sound and will be recorded by the noise monitor. As a result, when statistical data is compiled later, windy days without construction will also be recorded as a day when noise is generated, resulting in the data being untrue and requiring personnel to re-check. Therefore, in order to solve this problem, a function is needed to automatically close the noise monitor in a windy environment to isolate the wind sound and improve the accuracy of the data in later data statistics.

[0003] After searching, the patent document with publication number CN218822741U provides a noise detection sensor for urban acoustic environment. The utility model discloses an environmental noise monitor for wind interference prevention, including a mounting frame and a noise detector, and the first slide grooves are provided on the left and right sides of the inner wall of the mounting frame. The device drives the connecting shaft to rotate through the cup fan, and the connecting shaft will drive the rotating rod and the counterweight block to rotate at high speed under the state of high-speed rotation, so that the rotating rod will continue to expand outward, thereby pushing the push plate upward, and the noise detector is driven by the first rack, the gear and the second rack to be stored in the interior of the mounting frame. This function can only be realized in an environment with strong wind and continuous wind output is required. The noise detector is completely stored and soundproofed by the power of wind, which can prevent the noise detector from mistaking the wind for noise, which brings inconvenience to the later data calculation. In addition, this method is the utilization of wind energy, does not require manual intervention, and the function is fully automatic, which is suitable for outdoor environments such as construction sites.

[0004] This technical document utilizes wind energy to allow the detector to enter the soundproof box. However, after entering the soundproof box, the detector cannot work and continues to consume electrical energy. The detector also consumes energy when entering and exiting the soundproof box, which increases the cost of use.

[0005] Therefore, it is necessary to invent urban acoustic environment noise detection sensors to solve the above problems. Utility Model Content

An energy-saving mechanism 3 is arranged above the noise sensor 2. The energy-saving mechanism 3 includes a sliding rod 301 fixedly connected to the inner wall of the fixed box 1, and the outer wall of the sliding rod 301 is slidably connected to a moving seat 302. The sliding of the moving seat 302 is achieved by the cooperation of the sliding rod 301 and the moving seat 302. The inner wall of the moving seat 302 is threadedly connected to a threaded rod 303. The rotation of the rod 303 realizes the left and right movement of the moving seat 302. One end of the threaded rod 303 is fixedly connected to the connecting sleeve 304. The end of the threaded rod 303 away from the connecting sleeve 304 is fixedly connected to the two-way reset spring 305. The two-way reset spring 305 is fixedly connected to the inner wall of the fixed box 1. The two-way reset spring 305 is located below the sliding rod 301.
