Description

Technical Field

[0001] This utility model relates to the field of noise monitoring instrument fixing technology, and in particular to a noise monitoring instrument fixing device for environmental protection acceptance. Background Technology

[0002] Environmental protection noise monitoring instruments are devices specifically designed to detect and record sound levels. They are widely used in urban environments, industrial areas, and transportation systems to monitor noise pollution. A noise monitoring instrument mainly consists of a microphone (or sound pressure sensor), a signal processor, and a data logger. The microphone captures sound waves, the signal processor analyzes the frequency and intensity of the sound waves, and the data logger stores or displays the measurement results in real time.

[0003] During environmental protection acceptance inspections, when using noise monitoring instruments, inspectors may choose to use handheld noise detectors or place them on the inspection ground. However, handheld noise detectors present several challenges: first, sound attenuates during propagation due to air absorption and reflection, causing fluctuations in noise intensity as the distance or angle between the detector and the noise source changes; second, handheld testing may be affected by human movement and airflow, leading to unstable measurement results; and third, for directional noise sources, the placement and angle of the handheld detector directly impact the measurement results.

[0004] Placing the noise meter on the acceptance surface for testing reduces interference from handheld operation to some extent, but some problems still exist. First, ground reflection and obstruction may cause sound attenuation, affecting the measurement results. Second, ground placement is easily affected by ambient background noise, especially in complex urban environments where vehicles and pedestrians are significant sources of background noise. Third, ground placement may not accurately reflect the noise level at a specific height (such as ear height). Utility Model Content

[0005] The main purpose of this utility model is to provide a fixing device for a noise monitoring instrument used in environmental protection acceptance, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A noise monitoring instrument fixing device for environmental protection acceptance includes a tripod base, tripod legs, telescopic legs, a tripod adjustment platform, a connecting ball, and fasteners. Multiple tripod legs are connected to the lower end of the tripod base, and each tripod leg has a telescopic leg connected to its lower end for adjusting the placement height or handheld length. The connecting ball is mounted on the tripod base via the tripod adjustment platform and is fixed to the tripod adjustment platform by fasteners, facilitating adjustment of the connecting ball's angle.

[0008] The two ends of the connecting ball are respectively equipped with a first angle adjustment platform and a second angle adjustment platform. Both the first angle adjustment platform and the second angle adjustment platform are equipped with quick-release screws. One of the quick-release screws is connected to a detector. The top of the detector is equipped with a sound detection head, which is used to realize the noise detection operation in environmental protection acceptance.

[0009] Another quick-release screw is connected to a clip, and a telescopic clip is connected to the clip. The telescopic clip and the clip hold another detector.

[0010] As an optional solution of this application, both the first angle adjustment platform and the second angle adjustment platform include a connecting rod and a circular platform.

The first angle adjustment platform and the second angle adjustment platform are connected in the screw holes of the connecting ball and are used to adjust the included angle between the first angle adjustment platform and the second angle adjustment platform. The included angle adjustment range is from zero degrees to ninety degrees.

[0012] As an optional solution in this application, the specifications of the two quick-release screws are 1 / 4 inch and 3 / 8 inch, respectively. The tester is adapted to connect with the 1 / 4 inch quick-release screw, and the 3 / 8 inch quick-release screw is threadedly connected with the clip.

The telescopic clip is designed in a "U" shape, and the telescopic clip is inserted into the opening of the clip. A return spring is provided at the connection between the telescopic clip and the clip.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The combination of tripod legs and telescopic legs allows the noise monitoring device to adapt to various complex usage environments and needs. By adjusting the height of the telescopic legs, not only can the device be placed stably, but the handheld length can also be flexibly adjusted, facilitating noise monitoring by acceptance personnel in different situations.
