Description

Technical Field

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

[0002] Noise monitoring can help assess the noise pollution in the environment and provide a scientific basis for relevant departments to formulate effective environmental protection and noise control measures. Noise monitoring is achieved through a noise monitor, which consists of a monitoring body and a microphone sensor. The microphone sensor uses the vibration of sound waves to change the diaphragm inside it, and converts the sound signal into an electrical signal output through the principles of electromagnetic induction or capacitance change. The electrical signal is transmitted to the monitoring body, which processes the signal and then displays it on the display.

[0003] When monitoring noise through a noise monitor, only the noise at the same height can be monitored. When the noise source is at a high place, when monitoring it on the ground, due to a certain distance, the noise monitor will not monitor accurately. Therefore, the present application provides an environmental noise monitoring device to meet the needs. Utility Model Content

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, by setting up a winding component and a balloon, the winding component is retracted and released, so that the balloon drives the microphone sensor to float upward, so that the microphone sensor can monitor noise at different heights, making the monitoring more accurate.

[0017] By setting up the rotating component and the measuring component, after the balloon floats upward, when there is wind, the wind will drive the balloon to move, causing the pull rope to tilt. By rotating the circular plate, the rotating cylinder is made parallel to the direction of the wind. After the pull rope is tilted, it drives the rotating cylinder to rotate, and the rotating cylinder drives the pointer to rotate.

The square plate does not need manual adjustment during rotation, and it automatically adjusts according to the wind direction. The adjustment is more convenient. After being parallel to the wind, the inclination angle of the pull rope is more accurate, and the monitoring is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the pull rope 68 is fixedly connected to the bottom of the microphone sensor 4, and the top of the wire 5 is electrically connected to the microphone sensor 4. A ring plate 62 is fixedly sleeved on the surface of the microphone sensor 4, a round rod 63 is fixed on the top of the ring plate 62, a fixed plate 64 is fixed on the top of the round rod 63, and a balloon 65 is fixed on the top of the fixed plate 64. Scale lines are provided on the surface of the pull rope 68, and one end of the wire 5 away from the microphone sensor 4 is electrically connected to the monitoring body 3. The servo motor 672 is connected through a servo controller, and the servo controller controls the forward and reverse rotation and start and stop of the servo motor 672. The scale lines on the surface of the pull rope 68 start from the bottom of the microphone sensor 4.

[0032] like Figure 3 As shown, an inclined rod 9 is fixed at the bottom of the support plate 69, and the bottom of the inclined rod 9 is fixedly connected to the surface of the support rod 2. The inclined rod 9 shares the force on the support plate 69, making the support plate 69 more secure during use.

No manual rotation is required, and the rotation is more convenient. The wind guide plate 8 is a transparent acrylic plate. The transparent material of the wind guide plate 8 can avoid affecting the reading of the protractor 72.

[0037] Working principle: when only the noise at the ground position needs to be monitored, the microphone sensor 4 is started, and after monitoring by the microphone sensor 4, the data is transmitted to the monitoring body 3 through the wire 5 and displayed;

[0038] When the noise source is high and there is no wind, the servo motor 672 is started, the servo motor 672 drives the reel 671 to rotate, the reel 671 unwinds the pull rope 68, and the balloon 65 floats upward, the balloon 65 drives the fixing plate 64 to move upward, the fixing plate 64 drives the round rod 63 to move upward, the round rod 63 drives the ring plate 62 to move upward, and the ring plate 62 drives the microphone sensor 4 to move upward, so that the microphone sensor 4 is closer to the noise source and the detection is more accurate;

When the balloon 65 floats, the balloon 65 is tilted by the wind, the airflow drives the pull rope 68 to tilt, the pull rope 68 drives the rotating cylinder 71 to tilt, and the rotating cylinder 71 drives the pointer 73 to tilt. At this time, the angle of the pointer 73 pointing to the protractor 72 and the distance of the pull rope 68 unwinding can be observed, and the vertical distance between the microphone sensor 4 and the ground can be calculated, making the detection more accurate;

[0040] When the detection is completed, the servo motor 672 is started in reverse, and the servo motor 672 drives the winding drum 671 to rotate in reverse, and the pull rope 68 is wound by the winding drum 671 to move the balloon 65 down.
