Description

Technical Field

[0001] This utility model belongs to the field of noise detection technology, and specifically relates to an adjustable environmental noise detection device. Background Technology

[0002] In existing technologies, noise detection typically relies on personnel holding handheld detection equipment. However, for electrical equipment located at heights, such as power plant boilers, generators, and turbines, this traditional method is not only inefficient but also poses safety hazards. To address this issue, some auxiliary devices have been designed to support the vertical adjustment of noise detectors. However, these devices often only allow for vertical height adjustment and cannot adjust the horizontal position.

[0003] While a patent document discloses a noise detection auxiliary device that solves the above-mentioned technical problems, it has low accuracy and the noise detector can only be adjusted along the length of the base, not along the width of the base, resulting in low convenience.

[0004] Therefore, it is necessary to design an adjustable environmental noise detection device to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model proposes an adjustable environmental noise detection device. The setting of the first telescopic cylinder and the second telescopic cylinder enables the noise detector to be adjusted in both vertical and horizontal directions. This multi-directional adjustment capability not only adapts to noise sources at different heights, but also allows for precise adjustment of the horizontal position of the noise detector as needed, thereby improving the adaptability and detection accuracy of the device.

[0006] The technical solution of this utility model is:

[0007] This utility model proposes an adjustable environmental noise detection device, comprising:

This multi-directional adjustment capability not only adapts to noise sources of different heights, but also allows for precise adjustment of the horizontal position of the noise detector as needed, thereby improving the adaptability and detection accuracy of the equipment.

[0023] (2) By cooperating with the drive motor and the lead screw, the sliding block can move precisely on the slide, which further improves the horizontal adjustment accuracy of the noise detector, enabling the equipment to be finely adjusted according to actual needs, thus ensuring the accuracy of the test results.
